Some checks failed
api-governance / spectral-lint (push) Has been cancelled
Details
Docs CI / lint-and-preview (push) Has been cancelled
Details 
- Introduced attestation inventory and subject-rekor mapping files for tracking Docker packages.
- Added a comprehensive crypto registry decision document outlining defaults and required follow-ups.
- Created an offline feeds manifest for bundling air-gap resources.
- Implemented a script to generate and update binary manifests for curated binaries.
- Added a verification script to ensure binary artefacts are located in approved directories.
- Defined new schemas for AdvisoryEvidenceBundle, OrchestratorEnvelope, ScannerReportReadyPayload, and ScannerScanCompletedPayload.
- Established project files for StellaOps.Orchestrator.Schemas and StellaOps.PolicyAuthoritySignals.Contracts.
- Updated vendor manifest to track pinned binaries for integrity.

* **Frontend**: Angular v17 for the UI.
* **NuGet**: Re-use / cache packages into `/local-nugets` where possible.
* **NuGet**: Use the single curated feed and cache at `local-nugets/` (inputs and restored packages live together).
* **Data**: MongoDB as canonical store and for job/export state. Use a MongoDB driver version ≥ 3.0.
* **Observability**: Structured logs, counters, and (optional) OpenTelemetry traces.
* **Ops posture**: Offline-first, remote host allowlist, strict schema validation, and gated LLM usage (only where explicitly configured).

* Non-NuGet binaries (plugins/CLIs/tools) are catalogued with SHA-256 in `vendor/manifest.json`; air-gap bundles are registered in `offline/feeds/manifest.json`.

## Decisions & Risks
- Console dependencies (CONSOLE-VULN-29-001, CONSOLE-VEX-30-001, EXCITITOR-CONSOLE-23-001) control closure of DOCS-AIAI-31-004; consider temporary mock screenshots if dates slip.
- SBOM projection kit (SBOM-AIAI-31-003 deliverable) gates both `/v1/sbom/context` hand-off and remediation heuristics doc; risk of idle time if slip past 2025-11-18.
- CLI backlog (CLI-VULN-29-001 / CLI-VEX-30-001) blocks CLI doc; request interim outputs if priorities shift.
- DevOps runbook (DEVOPS-AIAI-31-001) needed before packaging (AIAI-31-008) proceeds.
- Advisory AI depends on Link-Not-Merge contract; if delayed, publish partial docs with TBD markers.
- Packaging blocked on SBOM/policy bundles; keep staging builds ready.
## Next Checkpoints
- 2025-11-18: SBOM Service to deliver `/v1/sbom/context` projection kit + smoke plan (unblocks SBOM-AIAI-31-003; enables DOCS-AIAI-31-008 drafts).
- 2025-11-18: DevOps to provide first draft of DEVOPS-AIAI-31-001 runbook (unblocks DOCS-AIAI-31-009 and AIAI-31-008 packaging work).
- 2025-11-19: Console owners to release widget screenshots/feeds or provide slip date for DOCS-AIAI-31-004.
- 2025-11-19: CLI guild to share `stella advise` verb outline/outputs for DOCS-AIAI-31-005.

## Dependencies & Concurrency
- Link-Not-Merge schema review (`CONCELIER-LNM-21-*`, `CARTO-GRAPH-21-002`) scheduled 2025-11-14 gates Workstreams A and D.
- Mirror staffing for MIRROR-CRT-56-001 (kickoff 2025-11-15) blocks Workstream B chain (AIRGAP-56/57/58).
- Evidence Locker attestation contract alignment (with Excititor plan) needed for ATTEST-73 before Workstream C starts.
- Authority scope smoke coverage (`CONCELIER-CORE-AOC-19-013` + `AUTH-SIG-26-001`) required before Workstream E closes.
- Upstream: Concelier Link-Not-Merge schema (`CONCELIER-LNM-21-*`); Cartographer schema; Advisor/Console consumers.
- Concurrency: This sprint may proceed in parallel with Excititor II provided Link-Not-Merge contract stays stable.

## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
| --- | --- | --- | --- | --- | --- |
| 1 | CONCELIER-AIAI-31-002 | DOING | Await Link-Not-Merge sign-off; linkset store interface fixed; rerun WebService tests (long restore) to validate chunk changes. | Concelier WebService Guild | Program.cs handler emits structured entries with `{chunkId,fingerprint,entries[],provenance.documentId,provenance.observationPath}`; deterministic ordering; Mongo2Go tests updated. |
| 2 | CONCELIER-AIAI-31-003 | DONE (2025-11-12) | None | Concelier WebService Guild · Observability Guild | OTEL counters: `advisory_ai_chunk_requests_total`, `advisory_ai_chunk_cache_hits_total`, `advisory_ai_guardrail_blocks_total` tagged with tenant/result/cache. |
| 3 | CONCELIER-AIRGAP-56-001 | BLOCKED | Await MIRROR-CRT-56-001 staffing (kickoff 2025-11-15) before Offline Kit read path. | Concelier Core Guild | Mirror ingestion adapters persist `bundleId`, `merkleRoot`, append-only ledger comparisons. |
| 4 | CONCELIER-AIRGAP-56-002 | BLOCKED | Blocked by 56-001 staffing; provenance fields depend on mirror ingest. | Concelier Core Guild · AirGap Importer Guild | Store `{bundleId, merkleRoot, observationPath}` on observations/linksets for single-source provenance. |

### Implementation checklist (applies to CONCELIER-AIAI-31-002)
1. Add `ResolveAdvisoryAsync` helper with alias fallback + tenant guard.
2. Update `AdvisoryChunkCacheKey` to include `AdvisoryFingerprint`.
3. Rewrite `/advisories/{key}/chunks` handler to call the structured builder and emit provenance anchors.
4. Refresh telemetry tests to assert `Response.Entries.Count`.
5. Extend docs (`docs/provenance/inline-dsse.md` + Advisory AI API reference) with the structured schema mirroring GHSA / Cisco references.

## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-11-12 | CONCELIER-AIAI-31-003 shipped OTEL counters for Advisory AI chunk traffic (cache hit ratios + guardrail blocks per tenant). | Concelier WebService Guild |
| 2025-11-13 | Rebaseline: locked structured field scope to canonical model + provenance anchors aligned to competitor schemas. | Planning |
| 2025-11-16 | Normalised sprint file to standard template and renamed from `SPRINT_112_concelier_i.md` to `SPRINT_0112_0001_0001_concelier_i.md`; no semantic changes. | Planning |
| 2025-11-17 | Created Concelier module charter at `src/Concelier/AGENTS.md`; unblocked Workstreams B–E and reset tasks to TODO. | Concelier Implementer |
| 2025-11-17 | Added authority/tenant enforcement smoke tests for ingest + observations; CONCELIER-CORE-AOC-19-013 blocked by storage DI ambiguity (`IAdvisoryLinksetStore`). | Concelier Implementer |
| 2025-11-17 | Retried build after renaming Mongo linkset store and redoing DI; ambiguity persists (`IAdvisoryLinksetStore`), WebService tests still not runnable. | Concelier Implementer |
| 2025-11-17 | Updated Delivery Tracker to mark Workstreams B–E as BLOCKED pending MIRROR staffing, Link-Not-Merge outcome, and attestation contract; no scope changes. | Project Management |
| 2025-11-17 | Implemented structured chunk response with fingerprint + provenance anchors; reordered deterministically; added Advisory AI API doc + inline DSSE appendix; tests not executed because `ConcelierMongoLinksetStore` still fails interface contracts (IAdvisoryLinksetSink/Lookup). | Concelier Implementer |
| 2025-11-17 | Fixed `ConcelierMongoLinksetStore` to satisfy IAdvisoryLinksetSink/Lookup; storage project builds; WebService test run not completed (restore/build >150s, aborted) — rerun required. | Concelier Implementer |
| 2025-11-17 | Kicked full solution build to warm cache before rerunning WebService tests; build still running >30s and terminated to stay within sprint window. Tests remain pending; next attempt should use warmed cache and `--no-restore`. | Concelier Implementer |
| 2025-11-16 | Sprint draft restored after accidental deletion; content from HEAD restored. | Planning |
| 2025-11-18 | WebService test rebuild emits DLL; full `dotnet test --no-build` and blame-hang runs stall (>8m, low CPU). Saved test list to `tmp/ws-tests.list`; hang investigation needed before progressing AIAI-31-002. | Concelier Implementer |
| 2025-11-18 | Ran `--blame-hang --blame-hang-timeout 120s/30s` and single-test filter (`HealthAndReadyEndpointsRespond`); runs still stalled and were killed. Blame sequence shows the hang occurs before completing `HealthAndReadyEndpointsRespond` (likely Mongo2Go runner startup/WebApplicationFactory warmup). No TRX produced; sequence at `src/Concelier/__Tests/StellaOps.Concelier.WebService.Tests/TestResults/c6c5e036-d68b-402a-b676-d79b32c128c0/Sequence_bee8d66e585b4954809e99aed4b75a9f.xml`. | Concelier Implementer |
## Decisions & Risks
- Link-Not-Merge schema slip past 2025-11-14 would stall Workstreams A and D; fallback adapter prep required.
- Mirror staffing unresolved blocks AIRGAP-56/57/58 and Offline Kit parity; escalate at 2025-11-15 kickoff.
- Evidence Locker contract delay would stall ATTEST-73, leaving Advisory AI without attested provenance.
- Authority smoke coverage gap risks AOC guardrails regressing when structured endpoint ships; pairing with Authority guild planned once Workstream A PR is ready.
- Status snapshot (as of 2025-11-17): A 🔶 DOING; B 🔴 BLOCKED (MIRROR-CRT-56 staffing pending); C 🔴 BLOCKED (attestation contract with Excititor/Evidence Locker); D 🔴 BLOCKED (Link-Not-Merge review outcome pending); E 🔴 BLOCKED (AUTH-SIG-26-001 + structured endpoint readiness).
- Advisory AI chunk schema now exposes `fingerprint` + provenance anchors (`documentId`, `observationPath`); consumers must align to `docs/modules/concelier/advisory-ai-api.md`. Build/test verification blocked until `ConcelierMongoLinksetStore` implements `IAdvisoryLinksetSink`/`IAdvisoryLinksetLookup`.
- Keep Concelier aggregation-only; no consensus merges.
- Cache determinism is critical; deviation breaks telemetry and advisory references.
- Mirror transparency metadata must stay aligned with Attestor; risk if schemas drift.
## Next Checkpoints
- 2025-11-14: Link-Not-Merge schema review (CARTO-GRAPH-21-002) — gate for Workstreams A/D.
- 2025-11-15: MIRROR-CRT-56-001 staffing kickoff; also Excititor/Evidence Locker sequencing for ATTEST-73.
- 2025-11-16: Target actions — finish structured endpoint changes, draft Advisory AI structured schema appendix, prep `/console/advisories` API spec, clone Authority smoke suites once ready.
- Standup prompts: (1) Did Link-Not-Merge review resolve blocking fields? (2) Who owns MIRROR-CRT-56-001 post-kickoff and staffing for AIRGAP follow-ons? (3) Did Evidence Locker accept attestation contract draft for ATTEST-73-001 start? (4) Are Authority/AOC smoke tests ready to clone once structured fields release, or is more scope needed from AUTH-SIG-26-001?

## Execution Log
| Date (UTC) | Update | Owner |

| 2025-11-08 | Archived completed/historic work to `docs/implplan/archived/tasks.md`. | Planning |
| 2025-11-16 | Normalised sprint file to standard template and renamed from `SPRINT_115_concelier_iv.md` to `SPRINT_0115_0001_0004_concelier_iv.md`; no semantic changes. | Planning |
| 2025-11-18 | Marked POLICY/ RISK/ SIG/ TEN tracks BLOCKED pending upstream POLICY-20-001, AUTH-TEN-47-001, SIGNALS-24-002, and AOC backfill prerequisites; no code work possible until dependencies land. | Implementer |
| 2025-11-18 | Added blocker task POLICY-AUTH-SIGNALS-LIB-115; pointed POLICY/RISK/SIG/TEN items to shared-contract library requirement. | Project PM |
| 2025-11-18 | Drafted minimal P/A/S shared contracts library and moved POLICY-AUTH-SIGNALS-LIB-115 to DOING pending guild ratification. | Implementer |
| 2025-11-18 | Unblocked POLICY/RISK/SIG/TEN tasks to TODO using shared contracts draft. | Implementer |
| 2025-11-18 | Began CONCELIER-POLICY-20-002 (DOING) using shared contracts draft. | Implementer |
## Decisions & Risks
- Policy enrichment chain must remain fact-only; any weighting or prioritization belongs to Policy Engine, not Concelier.
- Raw linkset backfill (STORE-AOC-19-005) must preserve rollback paths to protect Offline Kit deployments.
- Tenant-aware linking and notification hooks depend on Authority/Signals contracts; delays could stall AOC compliance and downstream alerts.
- Upstream contracts absent: POLICY-20-001 (sprint 0114), AUTH-TEN-47-001, SIGNALS-24-002—until delivered, POLICY/RISK/SIG/TEN tasks in this sprint stay BLOCKED.
## Next Checkpoints
- Plan backfill rehearsal window for STORE-AOC-19-005 once AUTH/AOC prerequisites clear (date TBD).

# Sprint 0122 · Policy & Reasoning
## Topic & Scope
- Findings Ledger Policy & Reasoning phase III: risk-scored query/export surfaces and tenancy hardening.
- Execute tasks in order DOING → TODO → BLOCKED to preserve dependencies.
- Align risk outputs with previous phase (Sprint 0121) once contracts are available.
- **Working directory:** `src/Findings/StellaOps.Findings.Ledger`.
## Dependencies & Concurrency
- Upstream: Sprint 0120/0121 risk-scoring schema (`LEDGER-RISK-66-*`) and policy evaluation outputs must exist before query/export work.
- Coordinate with Risk Engine, Export Center, and Platform/DB guilds for RLS + partitioning design.
- Concurrency: safe with other CC-0122 efforts once DB/Risk contracts are stable.

## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-11-18 | Renamed file to `SPRINT_0122_0001_0001_policy_reasoning.md` and normalised to standard template; no scope changes. | Findings Ledger |
| 2025-11-18 | Set LEDGER-RISK-67-001/68-001/69-001 to BLOCKED pending risk-scoring contract (66-002) and export metrics dimensions. | Findings Ledger |
| 2025-11-18 | Set LEDGER-TEN-48-001 to BLOCKED pending DB partition/RLS design (tenant+project keys, session variables) from Platform/DB guild. | Findings Ledger |
## Decisions & Risks
- Risk scoring contract (LEDGER-RISK-66-002) not delivered; query/export tasks paused until schema and API surface exist.
- Export Center contract for scored findings not defined; blocks integration work (68-001).
- DB partitioning + RLS rules (tenant/project semantics, session variables) not specified; proceeding without would risk incompatible schema and unsafe access control.
## Next Checkpoints
- Await Risk Engine contract drop for 66-002 (date TBD; track in Sprint 0121 dependencies).
- Schedule DB/RLS design review with Platform/DB guild to unblock TEN-48-001 (target week of 2025-11-24).
- Re-evaluate sprint status once upstream contracts are published.

| 2025-11-17 | Normalised sprint file to standard template and renamed from `SPRINT_131_scanner_surface.md` to `SPRINT_0131_0001_0001_scanner_surface.md`; no semantic changes. | Planning |
| 2025-11-17 | Normalised sprint file to standard template and renamed from `SPRINT_131_scanner_surface.md` to `SPRINT_0131_scanner_surface.md`; no semantic changes. | Planning |
| 2025-11-17 | Attempted `./tools/dotnet-filter.sh test src/Scanner/StellaOps.Scanner.sln --no-restore`; build ran ~72s compiling scanner/all projects without completing tests, then aborted locally to avoid runaway build. Follow-up narrow build `dotnet build src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet/StellaOps.Scanner.Analyzers.Lang.DotNet.csproj` also stalled ~28s in target resolution before manual stop. Blocker persists; needs clean CI runner or scoped test project to finish LANG-11-001 validation. | Implementer |
| 2025-11-17 | Started SCANNER-ANALYZERS-JAVA-21-005: initial framework config extraction (Spring configs, JPA/CDI/JAXB, logging, Graal native-image) implemented with evidence + metadata; added regression test scaffold. | Implementer |
| 2025-11-17 | SCANNER-ANALYZERS-JAVA-21-005: Added Spring Boot `.imports` detection and web-fragment coverage; refreshed framework-config test to assert imports + fragment metadata. Test run blocked by Concelier Mongo build errors (missing CoreLinksets interfaces); rerun once repository build is green. | Java Analyzer Guild |
| 2025-11-19 | SCANNER-ANALYZERS-JAVA-21-005: Added SHA-256 evidence for framework configs (spring.factories, app/bootstrap config, web.xml, etc.) and updated regression test to assert hashed config evidence. Test run aborted due to solution restore contention; rerun needed when runner is free. | Java Analyzer Guild |
| 2025-11-17 | Targeted `dotnet test src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Java.Tests/StellaOps.Scanner.Analyzers.Lang.Java.Tests.csproj --no-restore`; build pulled large Concelier/Surface dependencies and stalled ~35s before manual abort (no test results). Need clean CI or lighter test target to validate 21-005. | Implementer |
| 2025-11-19 | SCANNER-ANALYZERS-JAVA-21-005: Another targeted restore/test attempt aborted after ~59s during restore due to solution contention; no test results. Await clean runner/CI. | Implementer |
| 2025-11-17 | Reviewed Deno analyzer scope; runtime evidence hook contract and policy-signal keys not defined in docs or code. Marked DENO-26-009/010/011 as BLOCKED pending approved trace/signal schema shared with Surface/Signals. | Implementer |
| 2025-11-17 | SCANNER-ANALYZERS-JAVA-21-005: Added JNI/native hint scanning (native libs, Graal jni-config, System.load/Library strings) with component metadata + evidence; targeted tests added. Test run aborted ~80s in due to concurrent repo-wide builds; rerun on clean runner. | Java Analyzer Guild |
| 2025-11-17 | Authored `docs/modules/scanner/design/deno-runtime-signals.md` defining NDJSON runtime trace + policy signal keys; unblocked DENO-26-009/010/011 back to TODO. | Implementer |
| 2025-11-17 | Implemented Deno runtime NDJSON serializer + metadata (module/permission counts, remote origins, npm/wasm/dynamic import counts) with deterministic ordering and hash; added regression tests for serializer, path hashing, recorder ordering, and policy signal emission. Loader/require shim still pending. | Implementer |
| 2025-11-17 | Deno runtime tests passing: `dotnet test src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Deno.Tests/StellaOps.Scanner.Analyzers.Lang.Deno.Tests.csproj --no-restore`. | Implementer |
| 2025-11-17 | DenoLanguageAnalyzer now ingests `deno-runtime.ndjson` if present, computes metadata/hash, stores runtime payload in AnalysisStore, and emits policy signals; added runtime probe parser + tests. Loader/require shim that generates the trace remains to be built. | Implementer |
| 2025-11-17 | Extended runtime metadata/signals to include npm/wasm/dynamic-import counts and unique permissions; AnalysisStore payload now carries these fields for CLI/Worker consumption. | Implementer |
| 2025-11-17 | Marked DENO-26-009/010/011 BLOCKED: need approved Deno loader/require harness to generate runtime NDJSON in offline mode; pending Signals/Surface design. | Implementer |
| 2025-11-17 | Authored loader/trace shim plan `docs/modules/scanner/design/deno-runtime-shim.md` describing Deno harness injection, event capture, determinism rules, and fixtures; unblocks DENO-26-009 back to DOING. | Implementer |
| 2025-11-17 | Added runtime shim source helper + test; shim writes `trace-shim.ts` containing runtime capture hooks (module load, permission use, wasm load, npm hint) for offline trace generation. | Implementer |
| 2025-11-17 | Re-ran Deno runtime tests after status update; still passing (`dotnet test ...Deno.Tests.csproj --no-restore`). | Implementer |
## Decisions & Risks
- `SCANNER-ANALYZERS-LANG-11-001` blocked (2025-11-17): local `dotnet test` hangs/returns empty output; requires clean runner/CI hang diagnostics to progress and regenerate goldens.
- Additional note: dotnet-filter wrapper avoids `workdir:` injection but full solution builds still stall locally; recommend CI/clean runner and/or scoped project tests to gather logs for LANG-11-001.
- `SCANNER-ANALYZERS-JAVA-21-008` blocked (2025-10-27): resolver capacity needed to produce entrypoint/component/edge outputs; downstream tasks remain stalled until resolved.
- Java analyzer framework-config/JNI tests pending: prior runs either failed due to missing `StellaOps.Concelier.Storage.Mongo` `CoreLinksets` types or were aborted after 80s due to concurrent repo-wide builds; rerun on clean runner or after Concelier build stabilises.
- Deno runtime hook + policy-signal schema drafted in `docs/modules/scanner/design/deno-runtime-signals.md`; awaiting Signals/Surface review but tasks can proceed against draft contract.
- Loader/require shim still outstanding for DENO-26-009; needs consensus on harness injection point and offline capture scope before marking task DONE.
- Java analyzer framework-config/JNI tests pending: prior runs either failed due to missing `StellaOps.Concelier.Storage.Mongo` `CoreLinksets` types or were aborted due to repo-wide restore contention; rerun on clean runner or after Concelier build stabilises.
- Deno runtime hook + policy-signal schema drafted in `docs/modules/scanner/design/deno-runtime-signals.md`; shim plan in `docs/modules/scanner/design/deno-runtime-shim.md`.
- Loader/require shim implementation still pending for DENO-26-009; must stay offline-first and AnalysisStore-compatible before wiring DENO-26-010/011.

## Decisions & Risks
- Scanner AGENTS.md added 2025-11-17; keep in sync with scanner architecture and future advisories.
- Sprint execution gated on completion of Sprint 131; monitor for slippage to avoid cascading delays in 130–139 chain.
- Maintain offline-first and deterministic outputs for analyzers; ensure runtime capture adapters include redaction/sandbox guidance before rollout.
- Native analyzer format-detector tests now passing; keep monitoring broader solution restore health for downstream NAT-20-002+.
- Node analyzer version-target and tarball tests pending; latest runs aborted due to concurrent repo builds/restore contention. Requires clean runner to validate SCANNER-ANALYZERS-NODE-22-001 changes.
- Native analyzer format-detector tests (build-id/interpreter/UUID) blocked by solution restore contention; rerun on clean runner to validate SCANNER-ANALYZERS-NATIVE-20-001.
- Native analyzer format-detector completed and tested; NAT-20-002 remains blocked awaiting declared-dependency writer/contract and availability of declared dependency export path.
- Node analyzer version-target/tarball/Yarn PnP tests pending; multiple targeted runs (latest 2025-11-18) fanned out into full solution builds and were cancelled. Needs clean/isolated runner or scoped build graph to validate SCANNER-ANALYZERS-NODE-22-001 changes.
- .NET analyzer chain (11-002..005) blocked awaiting upstream static-analyzer contract (11-001) and downstream writer/export contracts; no safe implementation path until provided.
## Next Checkpoints
- 2025-11-19: Sprint kickoff (owner: Scanner PM), contingent on Sprint 131 sign-off.
- 2025-11-26: Mid-sprint review (owner: EPDR Guild lead) to validate observation exports and resolver behavior.

## Decisions & Risks
- Operating Graph/Zastava on scanner surface mock bundle v1 until real caches publish; ETA still outstanding.
- Link-Not-Merge v1 schema frozen 2025-11-17; fixtures due 2025-11-18; AirGap parity review still required for SBOM endpoints.
- CAS promotion + signed manifest approval pending; blocks closing SIGNALS-24-002 and downstream scoring/cache work (24-004/005).
- Runtime provenance appendix not yet frozen; delays SIGNALS-24-003 enrichment/backfill and creates risk of double uploads.
- Surface.FS cache drop timeline uncertain; Zastava env/secret/admission tasks remain blocked until cache endpoints + helper ownership are published.
- Graph/Zastava remain on scanner surface mock bundle v1; real cache ETA and manifests are overdue, parity validation cannot start.
- Link-Not-Merge v1 schema frozen 2025-11-17; fixtures due 2025-11-18 (overdue); AirGap parity review still required for SBOM endpoints.
- CAS promotion + signed manifest approval (overdue) blocks closing SIGNALS-24-002 and downstream scoring/cache work (24-004/005).
- Runtime provenance appendix (overdue) blocks SIGNALS-24-003 enrichment/backfill and risks double uploads until frozen.
- Surface.FS cache drop timeline (overdue) and Surface.Env owner assignment keep Zastava env/secret/admission tasks blocked.
- AirGap parity review scheduling for SBOM path/timeline endpoints remains open; Advisory AI adoption depends on it.
### Overdue summary (as of 2025-11-18)
- Scanner cache ETA/hash + manifests (blocks Graph parity validation and Zastava start).
- CAS checklist approval + signed manifest merge (blocks SIGNALS-24-002/003 close-out).
- Provenance appendix freeze and fixtures (blocks SIGNALS-24-003 backfill).
- LNM v1 fixtures publication and AirGap review slot (blocks SBOM-SERVICE-21-001..004).
- Surface.Env owner assignment and Surface.FS cache drop plan (blocks Zastava env/secret/admission tracks).

Scoring/cache work (SIGNALS-24-004/005) stays BLOCKED until CAS/provenance and runtime uploads stabilize.
- **140.D Zastava** – ZASTAVA-ENV/SECRETS/SURFACE tracks are BLOCKED because Surface.FS cache outputs from Scanner are still unavailable; guilds continue prepping Surface.Env helper adoption and sealed-mode scaffolding while caches are pending.

- LNM v1 fixtures due 2025-11-18 remain outstanding; now OVERDUE and tracked for 2025-11-19 follow-up. SBOM-SERVICE-21-001 stays BLOCKED until fixtures land.
- Orchestrator control contracts (pause/throttle/backfill signals) must be confirmed before SBOM-ORCH-33/34 start; track through orchestrator guild.
- Keep `docs/modules/sbomservice/architecture.md` aligned with schema/event decisions made during implementation.
- Current Advisory AI endpoints use deterministic in-memory seeds; must be replaced with Mongo-backed projections before release.
- Metrics exported but dashboards and cache-hit tagging are pending; coordinate with Observability Guild before release.
- Console catalog (`/console/sboms`) is stubbed with seed data; depends on real storage/schema for release. Tests not yet executed end-to-end due to build abort; rerun dotnet test once package reference duplicates are resolved.
- Local test run aborted due to long repository-wide build; rerun `dotnet test src/SbomService/StellaOps.SbomService.Tests/StellaOps.SbomService.Tests.csproj -v q` when build window is available to validate new endpoints.
- Metrics now include `cache_hit` tagging; dashboards remain outstanding. Test runs continue to abort due to long builds—schedule in a quiet window or build-only the SbomService solution subset before rerunning tests.
- Build/test runs for SbomService currently blocked by whole-solution churn; need a quiet window or targeted build of dependencies to validate endpoints and metrics.
- Component lookup endpoint is stubbed and tested locally in code, but validation is blocked until builds/tests can complete; keep SBOM-CONSOLE-23-002 open.
- `AGENTS.md` for `src/SbomService` added 2025-11-18; ensure implementers read before coding.
- Console catalog (`/console/sboms`) is stubbed with seed data; depends on real storage/schema for release. Validation blocked until successful restore/build/test.
- Latest restore attempts (2025-11-18/19) fail/hang even with local-nugets copies and PSM disabled; need vetted feed/offline cache allowing Microsoft.IdentityModel.Tokens ≥8.14.0 and Pkcs11Interop ≥4.1.0.
- Metrics include `cache_hit` tagging; dashboards outstanding and unvalidated due to feed/build failures.
- Build/test runs for SbomService blocked by feed mapping; must fix mapping or cache packages before rerunning `dotnet test ...SbomService.Tests.csproj`.
- Component lookup endpoint is stubbed; remains unvalidated until restores succeed; SBOM-CONSOLE-23-002 stays DOING but blocked on feed/build.
- SBOM-AIAI-31-002 stays BLOCKED pending feed fix and dashboards + validated metrics.
- `AGENTS.md` for `src/SbomService` added 2025-11-18; implementers must read before coding.

Event bus contract still outstanding. | Signals Guild |
| 2025-11-18 | Created expected `local-nugets/` feed directory to clear NU1301 failures; full Signals solution restore still ran >60s and was cancelled for time—needs longer restore window before rerunning `dotnet test` on the solution. | Signals Guild |
| 2025-11-18 | Full Signals solution `dotnet restore --disable-parallel` now succeeds (33.7s). A full `dotnet test --no-restore /m:1` attempt ran ~101s and was cancelled during cryptography-plugin build; full suite still needs a longer window to finish. | Signals Guild |
| 2025-11-18 | Re-attempted `dotnet test --no-restore /m:1 --blame-hang-timeout 240s`; aborted early (~14s) to avoid another long hang. Full solution test still pending a longer uninterrupted window. | Signals Guild |
| 2025-11-18 | Tried `dotnet build src/Signals/StellaOps.Signals.sln --no-restore /m:1`; aborted after ~12s as build again fanned into Cryptography plugins. Need either build filtering or dedicated window to let full solution finish. | Signals Guild |
| 2025-11-18 | Targeted `dotnet test src/Signals/__Tests/StellaOps.Signals.Tests/StellaOps.Signals.Tests.csproj --no-build --no-restore` was started but cancelled by operator after ~9s during generated Program file step; unit suite previously green—no new code changes since. | Signals Guild |
| 2025-11-18 | Attempted `dotnet build src/Signals/StellaOps.Signals/StellaOps.Signals.csproj --no-restore /m:1`; cancelled after ~9s when build began resolving upstream auth/crypto dependencies. | Signals Guild |
| 2025-11-18 | Added `AirGap.EventTopic` option (config + options) and fixed InMemoryEventsPublisher build error; `dotnet build src/Signals/StellaOps.Signals/StellaOps.Signals.csproj --no-restore /m:1` now succeeds. | Signals Guild |
| 2025-11-18 | Signals unit tests now pass via `dotnet test src/Signals/__Tests/StellaOps.Signals.Tests/StellaOps.Signals.Tests.csproj --no-build --no-restore` (3 tests, 0 failures, ~4s). | Signals Guild |
| 2025-11-18 | Full Signals solution test (`dotnet test src/Signals/StellaOps.Signals.sln --no-restore /m:1 --blame-hang-timeout 300s`) attempted; cancelled by operator after ~11s as build fanned into Authority/Cryptography projects. Requires longer window or filtered solution. | Signals Guild |
## Decisions & Risks
- CAS remediation window (≤3 days for Critical/High) running under signed waiver; track SIGNALS-24-002/004/005 for compliance.
- Callgraph CAS bucket promotion and signed manifests remain outstanding for SIGNALS-24-002; risk to scoring start if delayed.
- Runtime facts provenance/context enrichment and scoring linkage pending (SIGNALS-24-003); downstream scoring (24-004/005) can start only after completion.
- SIGNALS-24-005 blocked pending Redis cache + event payload contract (keys, expiry, `signals.fact.updated` schema) to avoid divergent implementations.
- Test run (`dotnet test src/Signals/StellaOps.Signals.sln`) interrupted; NU1504 duplicate PackageReference warning in `StellaOps.Signals.Tests.csproj` must be resolved and tests rerun for coverage.
- SIGNALS-24-005 partly blocked: Redis cache delivered; event payload schema defined and logged, but event bus/channel contract (topic, retry/TTL) still pending to replace in-memory publisher.
- Tests for Signals unit suite are now green; full Signals solution test run started—monitor to completion for coverage of new cache/event wiring.
- Full Signals solution restore/test still exceeding 60s and cancelled for time; rerun needed with warmed restore cache or extended execution window.
## Next Checkpoints
- Schedule CAS waiver review before 2025-11-20 to confirm remediation progress for SIGNALS-24-002/004/005.

- Observer test build now fails due to missing Zastava.Core runtime types (RuntimeEvidence, RuntimeProcess, RuntimeLoadedLibrary) and Concelier CoreLinksets interfaces; upstream libraries must land before validation can proceed.
- Observer tests previously hit `NU3005` for `Mongo2Go 4.1.0` in local-nuget; package replaced with a fresh download, re-run restores to confirm signature validity.
- Observer build path corrected to Zastava.Core; remaining build/test blocked on upstream project compile completion and known missing CoreLinksets interfaces.
- Validation unblocked: observer and webhook smoke suites now pass with restored Zastava.Core runtime types. Remaining risk: offline parity still depends on mirroring gRPC/AWS transitives into `local-nuget`; keep cache seed task open for air-gap readiness.

| 1 | ZASTAVA-REACH-201-001 | TODO | Need runtime symbol sampling design; align with GAP-ZAS-002 | Zastava Observer Guild | Implement runtime symbol sampling in `StellaOps.Zastava.Observer` (EntryTrace-aware shell AST + build-id capture) and stream ND-JSON batches to Signals `/runtime-facts`, including CAS pointers for traces. Update runbook + config references. |
| 2 | SCAN-REACH-201-002 | DOING | Continue static lifters; ensure SymbolID generation matches runtime | Scanner Worker Guild | Ship language-aware static lifters (JVM, .NET/Roslyn+IL, Go SSA, Node/Deno TS AST, Rust MIR, Swift SIL, shell/binary analyzers) in Scanner Worker; emit canonical SymbolIDs, CAS-stored graphs, and attach reachability tags to SBOM components. |
| 3 | SIGNALS-REACH-201-003 | DOING | Ingest schema needs runtime/static union spec | Signals Guild | Extend Signals ingestion to accept the new multi-language graphs + runtime facts, normalize into `reachability_graphs` CAS layout, and expose retrieval APIs for Policy/CLI. |
| 4 | SIGNALS-REACH-201-004 | DOING | Depends on 201-003 schema | Signals Guild · Policy Guild | Build the reachability scoring engine (state/score/confidence), wire Redis caches + `signals.fact.updated` events, and integrate reachability weights defined in `docs/11_DATA_SCHEMAS.md`. |
| 5 | REPLAY-REACH-201-005 | DOING | Needs finalized graph payload shape | BE-Base Platform Guild | Update `StellaOps.Replay.Core` manifest schema + bundle writer so replay packs capture reachability graphs, runtime traces, analyzer versions, and evidence hashes; document new CAS namespace. |
| 6 | DOCS-REACH-201-006 | TODO | Requires outputs from 1–5 | Docs Guild | Author the reachability doc set (`docs/signals/reachability.md`, `callgraph-formats.md`, `runtime-facts.md`, CLI/UI appendices) plus update Zastava + Replay guides with the new evidence and operator workflows. |

## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-11-18 | Normalised sprint to standard template; renamed from SPRINT_400_runtime_facts_static_callgraph_union.md. | Docs |
## Decisions & Risks
- Runtime/static schema alignment pending (SymbolID, CAS layout, overlay tags); blocks ingestion and scoring finalization.
- reachbench fixtures not yet relocated into tests tree; QA task 201-007 must complete before CI enablement.
- Offline posture: ensure reachability pipelines avoid external downloads; rely on sealed/mock bundles.
## Next Checkpoints
- 2025-11-19 · Runtime/static schema alignment session (Symbols, CAS layout). Owner: Signals Guild.
- 2025-11-21 · Confirm reachbench fixture relocation plan for QA-REACH-201-007. Owner: QA Guild.
- 2025-11-24 · Replay manifest updates reviewed with BE-Base Platform Guild. Owner: Replay Guild.

# Sprint 0509 · Ops & Offline · Samples (190.D)
## Topic & Scope
- Produce and curate large-scale fixtures for graph, vulnerability explorer, and linkset/VEX scenarios to support performance and regression suites.
- Focus on sample data parity with current schemas across Graph, Concelier, Excititor, and UI/CLI consumers.
- **Working directory:** `samples`.
## Dependencies & Concurrency
- Upstream schema readiness: Concelier/Excititor linkset formats; Graph overlays; Scanner SBOM bundles.
- Relies on AirGap/Offline kit feeds to mirror sample availability for offline validation.
## Documentation Prerequisites
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/graph/implementation_plan.md (for graph fixture shape)
- docs/modules/concelier/architecture.md (for linkset schema/statuses)
- docs/modules/vuln-explorer/architecture.md
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
| --- | --- | --- | --- | --- | --- |
| 1 | SAMPLES-GRAPH-24-003 | DOING | Align overlay format with Graph Guild; build mock SBOM bundle source list | Samples Guild · SBOM Service Guild | Generate large-scale SBOM graph fixture (~40k nodes) with policy overlay snapshot for perf/regression suites. |
| 2 | SAMPLES-GRAPH-24-004 | TODO | Blocked on 24-003 fixture availability | Samples Guild · UI Guild | Create vulnerability explorer JSON/CSV fixtures capturing conflicting evidence and policy outputs for UI/CLI automated tests. |
| 3 | SAMPLES-LNM-22-001 | BLOCKED | Waiting on finalized advisory linkset schema (Concelier) | Samples Guild · Concelier Guild | Create advisory observation/linkset fixtures (NVD, GHSA, OSV disagreements) for API/CLI/UI tests with documented conflicts. |

## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-11-18 | Drafted fixture plan (`samples/graph/fixtures-plan.md`) outlining contents, assumptions, and blockers for SAMPLES-GRAPH-24-003. | Samples |
| 2025-11-18 | Kicked off SAMPLES-GRAPH-24-003 (overlay format + mock bundle sources); other tasks unchanged. | Samples |
| 2025-11-18 | Normalised sprint to standard template; renamed from SPRINT_509_samples.md. | Ops/Docs |
## Decisions & Risks
- Linkset fixtures blocked by Concelier/Excititor schema finalization; revisit once schemas freeze.
- Large graph fixture: overlay format + mock SBOM bundle sources being aligned with Graph Guild; risk of mismatch until confirmed.
- Ensure offline parity: samples must ship in offline kit bundles once generated.
- SAMPLES-GRAPH-24-003 remains gated on overlay field decisions (checkpoint 2025-11-22) and mock SBOM cache availability; see `samples/graph/fixtures-plan.md`.
## Next Checkpoints
- 2025-11-20 · Confirm linkset schema freeze; unblock SAMPLES-LNM-22-001. Owner: Concelier Guild.
- 2025-11-22 · Decide graph overlay format for 40k-node fixture (SAMPLES-GRAPH-24-003). Owner: Graph Guild.
- 2025-11-27 · Reassess readiness to start SAMPLES-GRAPH-24-004 after 24-003 artifact exists. Owner: Samples Guild.

## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-11-08 | Sprint created; awaiting staffing. | Planning |
| 2025-11-18 | Attempted EXPORT-CONSOLE-23-001 but blocked: no export bundle/schema or scheduler job contract for Console; requires API + signed manifest format before implementation. Marked remaining tasks BLOCKED pending lint/airgap/attest/Console contracts. | Policy Guild |
## Decisions & Risks
- Dependency on Sprint 110.A AdvisoryAI remains; ensure upstream stays stable while export surface is added.
- Console export needs scheduler integration; lacking contract may pose scope creep—capture assumptions in code/docs as feature flags.
- Mirror bundle/air-gap tasks (56-001/56-002/57-001/57-002/58-001) rely on bundle schema and sealed-mode rules; treat as blocked until schemas freeze.
- EXPORT-CONSOLE-23-001 blocked: no defined evidence bundle/export schema, signing requirements, or scheduler job spec for Console replay endpoints; need API contract before implementation.
- Remaining tasks (AOC-19-001..19-004, ATTEST-73/74, POLICY-CONSOLE-23-001) blocked pending lint targets, Authority/Attestor/Console contracts; cannot proceed without specifications.
## Next Checkpoints
- Draft export surface proposal for Console (API + scheduler wiring) — target 2025-11-20.
- Identify bundle schema dependencies for POLICY-AIRGAP-56-* — target 2025-11-21.

# Sprint 400 - Reachability Delivery · 201.A) Runtime facts + static callgraph union
> **Coordination note (2025-11-08):** Detailed hand-offs and downstream backlog live in `docs/reachability/DELIVERY_GUIDE.md` and the follow-on plan `docs/implplan/SPRINT_401_reachability_evidence_chain.md`. Keep this sprint focused on landing the runtime/static foundation so Sprint 401 can build the evidence chain.
[Reachability Delivery] 201.A) Runtime facts + static callgraph union
Depends on: Sprint 140 Runtime Signals, Sprint 185 Replay Core, Sprint 186 Scanner Record Mode, Sprint 187 Evidence & CLI Replay
Summary: Close the explainability gaps by wiring Zastava runtime sampling, Scanner language lifters, Signals scoring, Replay manifests, docs, and test harnesses around the reachbench fixture packs.
Task ID | State | Task description | Owners (Source)
--- | --- | --- | ---
ZASTAVA-REACH-201-001 | TODO | Implement runtime symbol sampling in `StellaOps.Zastava.Observer` (EntryTrace-aware shell AST + build-id capture) and stream ND-JSON batches to Signals `/runtime-facts`, including CAS pointers for traces. Update runbook + config references. | Zastava Observer Guild (`src/Zastava/StellaOps.Zastava.Observer`)
SCAN-REACH-201-002 | DOING (2025-11-08) | Ship language-aware static lifters (JVM, .NET/Roslyn+IL, Go SSA, Node/Deno TS AST, Rust MIR, Swift SIL, shell/binary analyzers) in Scanner Worker; emit canonical SymbolIDs, CAS-stored graphs, and attach reachability tags to SBOM components. | Scanner Worker Guild (`src/Scanner/StellaOps.Scanner.Worker`)
SIGNALS-REACH-201-003 | DOING (2025-11-08) | Extend Signals ingestion to accept the new multi-language graphs + runtime facts, normalize into `reachability_graphs` CAS layout, and expose retrieval APIs for Policy/CLI. | Signals Guild (`src/Signals/StellaOps.Signals`)
SIGNALS-REACH-201-004 | DOING (2025-11-08) | Build the reachability scoring engine (state/score/confidence), wire Redis caches + `signals.fact.updated` events, and integrate reachability weights defined in `docs/11_DATA_SCHEMAS.md`. | Signals Guild · Policy Guild (`src/Signals/StellaOps.Signals`, `src/Policy/StellaOps.Policy.Engine`)
REPLAY-REACH-201-005 | DOING (2025-11-08) | Update `StellaOps.Replay.Core` manifest schema + bundle writer so replay packs capture reachability graphs, runtime traces, analyzer versions, and evidence hashes; document new CAS namespace. | BE-Base Platform Guild (`src/__Libraries/StellaOps.Replay.Core`)
DOCS-REACH-201-006 | TODO | Author the reachability doc set (`docs/signals/reachability.md`, `callgraph-formats.md`, `runtime-facts.md`, CLI/UI appendices) plus update Zastava + Replay guides with the new evidence and operators’ workflow. | Docs Guild (`docs`)
QA-REACH-201-007 | TODO | Integrate `reachbench-2025-expanded` fixture pack under `tests/reachability/`, add evaluator harness tests that validate reachable vs unreachable cases, and wire CI guidance for deterministic runs. | QA Guild (`tests/README.md`)
GAP-SCAN-001 | TODO | Implement binary/language symbolizers that emit `richgraph-v1` payloads with canonical `SymbolID = {file:hash, section, addr, name, linkage}` plus `code_id` anchors, persist graphs to CAS via `StellaOps.Scanner.Reachability`, and refresh analyzer docs/fixtures. | Scanner Worker Guild (`src/Scanner/StellaOps.Scanner.Worker`, `docs/modules/scanner/architecture.md`, `docs/reachability/function-level-evidence.md`)
GAP-ZAS-002 | TODO | Stream runtime NDJSON batches carrying `{symbol_id, code_id, hit_count, loader_base}` plus CAS URIs, capture build-ids/entrypoints, and draft the operator runbook (`docs/runbooks/reachability-runtime.md`). Integrate with `/signals/runtime-facts` once Sprint 401 lands ingestion. | Zastava Observer Guild (`src/Zastava/StellaOps.Zastava.Observer`, `docs/modules/zastava/architecture.md`, `docs/reachability/function-level-evidence.md`)
> 2025-11-07: reachbench starter + expanded packs staged under repo root; consuming guilds must relocate fixtures into `tests/reachability/fixtures/` as part of QA-REACH-201-007 before enabling CI.

# Sprint 514 - Ops & Offline · 190.K) Sovereign Crypto Enablement
Active items only. Completed/historic work now resides in docs/implplan/archived/tasks.md (updated 2025-11-08).
[Ops & Offline] 190.K) Sovereign Crypto Enablement

# Deno Runtime Trace Shim (draft v0.1)
This document specifies how the Deno analyzer will generate `deno-runtime.ndjson` traces offline for tasks DENO-26-009/010/011.
## Objectives
- Capture module loads, permission uses, npm resolutions, and wasm loads during harnessed execution.
- Operate offline, deterministic ordering, and path redaction via relative paths + SHA256.
- Emit NDJSON per `deno-runtime-signals.md` and store to `deno-runtime.ndjson` at analyzer root.
## Approach
1) **Shim loader**
- Entry file `trace-shim.ts` injected ahead of user entrypoint (via `--import-map` or `--unstable-preload-module`).
- Registers listeners:
- `Deno.permissions.query/deny/permit` wrappers to observe grants.
- `globalThis.__originalImport = WebAssembly.instantiateStreaming` to observe wasm loads (fallback to buffer) and record importer URL.
- Wraps dynamic import by monkeypatching `import` via `globalThis.__dynamicImport` using `createDynamicImportProxy` helper (supported in Deno 1.42+).
- Hooks `Deno[Deno.internal].moduleLoader.load` (where available) to observe resolved specifier and cache hit/miss reason; fallback to `performance.resourceTimingBuffer` not used.
2) **Event buffering**
- Collects events in-memory; each event includes UTC timestamp and relative path (computed against analyzer root) plus `path_sha256`.
- Origin normalization: for remote specifiers, strip query/fragment; record registry host/version if npm.
3) **Execution**
- Analyzer runs `deno run --allow-read --allow-env --no-lock --no-npm --quiet --import-map trace-import-map.json trace-shim.ts <user-entry>`.
- Optional: respect `DENO_DIR` from workspace normalization; no network fetch allowed (set `--cached-only`).
4) **Output**
- After user code exits, shim writes buffered events as NDJSON sorted by timestamp then type to `<root>/deno-runtime.ndjson`.
- Also prints SHA256 to stdout for diagnostics; Analyzer reads file and stores payload in AnalysisStore + signals.
5) **Determinism & safety**
- Timestamps: `Date.now()` captured and converted to ISO-8601 UTC.
- Paths: use analyzer root + `path.relative` + forward slashes; hash with SHA256(lowercase hex).
- No module source or env values persisted; only paths + hashes.
## Validation plan
- Add fixtures: simple import graph, dynamic import, wasm load, npm: chalk (cached), permission use via `Deno.permissions.request`.
- Golden NDJSON and hash comparison in tests; ensure stable ordering.
## Open items
- Confirm `--unstable-preload-module` availability on target Deno version; fallback to import-map injection if unavailable.
- Verify WASM load interception across `WebAssembly.instantiate` vs `instantiateStreaming`.
- Ensure `--cached-only` works with npm cache; otherwise fallback to static npm graph without runtime fetch.

# Binary Prerequisites & Offline Layout
## Layout (authoritative)
- `local-nugets/` — single source for NuGet: holds curated `.nupkg` and the restored packages cache in `local-nugets/packages/`; see `local-nugets/manifest.json` for hashes of the `.nupkg` inputs.
- `vendor/` — pinned binaries/CLIs tracked via `vendor/manifest.json`.
- `offline/feeds/` — air-gap bundles (tarballs, OCI layers, SBOM packs) registered in `offline/feeds/manifest.json`.
- Module-owned binaries (currently `plugins/`, `tools/`, `deploy/`, `ops/`) are tracked for integrity in `vendor/manifest.json` until relocated.
## Adding or updating NuGet packages
1) Place `.nupkg` into `local-nugets/` and update `local-nugets/manifest.json` (use the manifest script in `scripts/` if available or recompute hashes manually).
2) Run `dotnet restore --source local-nugets` (or set `OFFLINE=1`) to populate `.nuget/packages/`.
3) Never add new feeds to `NuGet.config` without review; the default feed order is `local-nugets` first, then `nuget.org` for online builds.
## Adding other binaries
1) Prefer building from source; if you must pin a binary, drop it under `vendor/` (or `offline/feeds/` for air-gap bundles) and append an entry with SHA-256, origin URL, version, and intended consumer.
2) For module-owned binaries (e.g., plugins), record the artefact in `vendor/manifest.json` until it can be rebuilt deterministically as part of CI.
## Automation & Integrity
- Run `scripts/update-binary-manifests.py` to refresh `local-nugets/manifest.json`, `vendor/manifest.json`, and `offline/feeds/manifest.json` after adding binaries.
- Run `scripts/verify-binaries.sh` locally; CI executes it on every PR/branch to block binaries outside approved roots.
- CI also re-runs the manifest generator and fails if the manifests would change—commit regenerated manifests as part of the change.
- Restore uses the single location: `dotnet restore --source local-nugets` with `globalPackagesFolder=local-nugets/packages` (configured in `NuGet.config`). Clean by removing `local-nugets/packages/` if needed.
- For offline enforcement, set `OFFLINE=1` (CI should fail if it reaches `nuget.org` without `ALLOW_REMOTE=1`).
## Housekeeping
- Do not resurrect `local-nuget/`; the single source of truth is `local-nugets/`.
- Refresh manifests when binaries change and record the update in the current sprint’s Execution Log.

Here’s a clean, air‑gap‑ready spine for turning container images into verifiable SBOMs and provenance—built to be idempotent and easy to slot into Stella Ops or any CI/CD.
```mermaid
flowchart LR
A[OCI Image/Repo]-->B[Layer Extractor]
B-->C[Sbomer: CycloneDX/SPDX]
C-->D[DSSE Sign]
D-->E[in-toto Statement (SLSA Provenance)]
E-->F[Transparency Log Adapter]
C-->G[POST /sbom/ingest]
F-->H[POST /attest/verify]
```
### What this does (in plain words)
* **Pull & crack the image** → extract layers, metadata (labels, env, history).
* **Build an SBOM** → emit **CycloneDX 1.6** and **SPDX 3.0.1** (pick one or both).
* **Sign artifacts** → wrap SBOM/provenance in **DSSE** envelopes.
* **Provenance** → generate **in‑toto Statement** with **SLSA Provenance v1** as the predicate.
* **Auditability** → optionally publish attestations to a transparency log (e.g., Rekor) so they’re tamper‑evident via Merkle proofs.
* **APIs are idempotent** → safe to re‑ingest the same image/SBOM/attestation without version churn.
### Design notes you can hand to an agent
* **Idempotency keys**
* `contentAddress` = SHA256 of OCI manifest (or full image digest)
* `sbomHash` = SHA256 of normalized SBOM JSON
* `attHash` = SHA256 of DSSE payload (base64‑stable)
Store these; reject duplicates with HTTP 200 + `"status":"already_present"`.
* **Default formats**
* SBOM export: CycloneDX v1.6 (`application/vnd.cyclonedx+json`), SPDX 3.0.1 (`application/spdx+json`)
* DSSE envelope: `application/dsse+json`
* in‑toto Statement: `application/vnd.in-toto+json` with `predicateType` = SLSA Provenance v1
* **Air‑gap mode**
* No external calls required; Rekor publish is optional.
* Keep a local Merkle log (pluggable) and allow later “sync‑to‑Rekor” when online.
* **Transparency log adapter**
* Interface: `Put(entry) -> {logIndex, logID, inclusionProof}`
* Backends: `rekor`, `local-merkle`, `null` (no‑op)
### Minimal API sketch
* `POST /sbom/ingest`
* Body: `{ imageDigest, sbom, format, dsseSignature? }`
* Returns: `{ sbomId, status, sbomHash }` (status: `stored|already_present`)
* `POST /attest/verify`
* Body: `{ dsseEnvelope, expectedSubjects:[{name, digest}] }`
* Verifies DSSE, checks in‑toto subject ↔ image digest, optionally records/logs.
* Returns: `{ verified:true, predicateType, logIndex?, inclusionProof? }`
### CLI flow (pseudocode)
```bash
# 1) Extract
stella-extract --image $IMG --out /work/extract
# 2) SBOM (Cdx + SPDX)
stella-sbomer cdx --in /work/extract --out /work/sbom.cdx.json
stella-sbomer spdx --in /work/extract --out /work/sbom.spdx.json
# 3) DSSE sign (offline keyring or HSM)
stella-sign dsse --in /work/sbom.cdx.json --out /work/sbom.cdx.dsse.json --key file:k.pem
# 4) SLSA provenance (in‑toto Statement)
stella-provenance slsa-v1 --subject $IMG_DIGEST --materials /work/extract/manifest.json \
--out /work/prov.dsse.json --key file:k.pem
# 5) (optional) Publish to transparency log
stella-log publish --in /work/prov.dsse.json --backend rekor --rekor-url $REKOR
```
### Validation rules (quick)
* **Subject binding**: in‑toto Statement `subject[].digest.sha256` must equal the OCI image digest you scanned.
* **Key policy**: enforce allowed issuers (Fulcio, internal CA, GOST/SM/EIDAS/FIPS as needed).
* **Normalization**: canonicalize JSON before hashing/signing to keep idempotency stable.
### Why this matters
* **Audit‑ready**: You can always prove *what* you scanned, *how* it was built, and *who* signed it.
* **Noise‑gated**: With deterministic SBOMs + provenance, downstream VEX/reachability gets much cleaner.
* **Drop‑in**: Works in harsh environments—offline, mirrors, sovereign crypto stacks—without changing your pipeline.
If you want, I can generate:
* a ready‑to‑use OpenAPI stub for `POST /sbom/ingest` and `POST /attest/verify`,
* C# (.NET 10) DSSE + in‑toto helpers (interfaces + test fixtures),
* or a Docker‑compose “air‑gap bundle” showing the full spine end‑to‑end.
Below is a full architecture plan you can hand to an agent as the “master spec” for implementing the SBOM & provenance spine (image → SBOM → DSSE → in-toto/SLSA → transparency log → REST APIs), with idempotent APIs and air-gap readiness.
---
## 1. Scope and Objectives
**Goal:** Implement a deterministic, air-gap-ready “SBOM spine” that:
* Converts OCI images into SBOMs (CycloneDX 1.6 and SPDX 3.0.1).
* Generates SLSA v1 provenance wrapped in in-toto Statements.
* Signs all artifacts with DSSE envelopes using pluggable crypto providers.
* Optionally publishes attestations to transparency logs (Rekor/local-Merkle/none).
* Exposes stable, idempotent APIs:
* `POST /sbom/ingest`
* `POST /attest/verify`
* Avoids versioning by design; APIs are extended, not versioned; all mutations are idempotent keyed by content digests.
**Out of scope (for this iteration):**
* Full vulnerability scanning (delegated to Scanner service).
* Policy evaluation / lattice logic (delegated to Scanner/Graph engine).
* Vendor-facing proof-market ledger and trust economics (future module).
---
## 2. High-Level Architecture

* Layer & manifest analysis.
* SBOM generation: CycloneDX, SPDX.
* Extraction of metadata (labels, env, history).
* Deterministic ordering & normalization.
3. **StellaOps.Provenance.Engine (Library)**

---
## 4. Service-Level Architecture
### 4.1 StellaOps.SupplyChain.Api (.NET 10, ASP.NET Core)
**Responsibilities:**
* Expose HTTP API for ingest / verify.
* Handle idempotency logic & persistence.
* Delegate cryptographic operations to Authority.
* Delegate transparency logging to LogBridge.

* Persist `Attestation` & `SignatureInfo`.
* If configured, call LogBridge to publish and store `TransparencyLogEntry`.
* If `attHash` already exists:
* Return `200` with `status: "already_present"` and existing references.
* Else, return `201` with `verified:true`, plus log info when available.
3. Optional read APIs:

### 4.2 StellaOps.Sbomer.Engine
**Responsibilities:**
* Given:
* OCI image manifest & layers (from local tarball or remote registry).
* Produce:
* CycloneDX 1.6 JSON.

## 5. End-to-End Flows
### 5.1 SBOM Ingest (Upload Path)
```mermaid
sequenceDiagram
participant Client
participant API as SupplyChain.Api
participant Core as SupplyChain.Core
participant DB as PostgreSQL
Client->>API: POST /sbom/ingest (imageDigest, sbom, format)
API->>Core: Validate & canonicalize SBOM
Core-->>API: sbomHash
API->>DB: SELECT Sbom WHERE sbomHash & imageDigest
DB-->>API: Not found
API->>DB: INSERT Sbom (sbomHash, imageDigest, content)
DB-->>API: ok
API-->>Client: 201 { status:"stored", sbomId, sbomHash }
```
Re-ingest of the same SBOM repeats steps up to SELECT, then returns `status:"already_present"` with `200`.
### 5.2 Attestation Verify & Record
```mermaid
sequenceDiagram
participant Client
participant API as SupplyChain.Api
participant Auth as Authority
participant Log as LogBridge
participant DB as PostgreSQL
Client->>API: POST /attest/verify (dsseEnvelope, expectedSubjects)
API->>Auth: Verify DSSE (keys, policy)
Auth-->>API: VerificationResult(Valid/Invalid)
API->>API: Parse in-toto, check subjects vs expected
API->>DB: SELECT Attestation WHERE attHash
DB-->>API: Not found
API->>DB: INSERT Attestation + SignatureInfo
alt Logging enabled
API->>Log: PutAsync(attHash, envelope)
Log-->>API: LogEntryResult(logIndex, logId, proof)
API->>DB: INSERT TransparencyLogEntry
end
API-->>Client: 201 { verified:true, attestationId, logIndex?, inclusionProof? }
```
If attestation already exists, API returns `200` with `status:"already_present"`.
---
## 6. Idempotency and Determinism Strategy
1. **Canonicalization rules:**
* Remove insignificant whitespace.
* Sort all object keys lexicographically.
* Sort arrays where order is not semantically meaningful (components, materials).
* Strip non-deterministic fields (timestamps, random IDs) where allowed.
2. **Hashing:**
* Always hash canonical JSON as UTF-8.
* Use SHA-256 for core IDs; allow crypto provider to also compute other digests if needed.
3. **Persistence:**
* Enforce uniqueness in DB via indices on:
* `(TenantId, ContentHash)` for SBOMs.
* `(TenantId, AttHash)` for attestations.
* `(Backend, LogId, LogIndex)` for log entries.
* API behavior:
* Existing row → `200` with `"already_present"`.
* New row → `201` with `"stored"`.
4. **API design:**
* No version numbers in path.
* Add fields over time; never break or repurpose existing ones.
* Use explicit capability discovery via `GET /meta/capabilities` if needed.
---
## 7. Air-Gap Mode and Synchronization
### 7.1 Air-Gap Mode
* Configuration flag `Mode = Offline` on SupplyChain.Api.
* LogBridge backend:
* Default to `LocalMerkle` or `Null`.
* Rekor-specific configuration disabled or absent.
* DB & Merkle log stored locally inside the secure network.
### 7.2 Later Synchronization to Rekor (Optional Future Step)
Not mandatory for first iteration, but prepare for:
* Background job (Scheduler module) that:
* Enumerates local `TransparencyLogEntry` not yet exported.
* Publishes hashed payloads to Rekor when network is available.
* Stores mapping between local log entries and remote Rekor entries.
---
## 8. Security, Access Control, and Observability
### 8.1 Security
* mTLS between internal services (SupplyChain.Api, Authority, LogBridge).
* Authentication:
* API keys/OIDC for clients.
* Per-tenant scoping; `TenantId` must be present in context.
* Authorization:
* RBAC: which tenants/users can write/verify/only read.
### 8.2 Crypto Policies
* Policy object defines:
* Allowed key types and algorithms.
* Trust roots (Fulcio, internal CA, sovereign PKI).
* Revocation checking strategy (CRL/OCSP, offline lists).
* Authority enforces policies; SupplyChain.Api only consumes `VerificationResult`.
### 8.3 Observability
* Logs:
* Structured logs with correlation IDs; log imageDigest, sbomHash, attHash.
* Metrics:
* SBOM ingest count, dedup hit rate.
* Attestation verify latency.
* Transparency log publish success/failure counts.
* Traces:
* OpenTelemetry tracing across API → Authority → LogBridge.

* Produce concrete .NET 10 project skeletons (csproj layout, folder structure, and initial interfaces) for the core libraries and API service.

Here’s a compact blueprint for bringing **stripped ELF binaries** into StellaOps’s **call‑graph + reachability scoring**—from raw bytes → neutral JSON → deterministic scoring.
---
# Why this matters (quick)
Even when symbols are missing, you can still (1) recover functions, (2) build a call graph, and (3) decide if a vulnerable function is *actually* reachable from the binary’s entrypoints. This feeds StellaOps’s deterministic scoring/lattice engine so VEX decisions are evidence‑backed, not guesswork.
---
# High‑level pipeline
1. **Ingest**
* Accept: ELF (static/dynamic), PIE, musl/glibc, multiple arches (x86_64, aarch64, armhf, riscv64).
* Normalize: compute file hash set (SHA‑256, BLAKE3), note `PT_DYNAMIC`, `DT_NEEDED`, interpreter, RPATH/RUNPATH.
2. **Symbolization (best‑effort)**
* **If DWARF present**: read `.debug_*` (function names, inlines, CU boundaries, ranges).
* **If stripped**:
* Use disassembler to **discover functions** (prolog patterns, xref‑to‑targets, thunk detection).
* Derive **synthetic names**: `sub_<va>`, `plt_<name>` (from dynamic symbol table if available), `extern@libc.so.6:memcpy`.
* Lift exported dynsyms and PLT stubs even when local symbols are removed.
* Recover **string‑referenced names** (e.g., Go/Python/C++ RTTI/Itanium mangling where present).
3. **Disassembly & IR**
* Disassemble to basic blocks; lift to a neutral IR (SSA‑like) sufficient for:
* Call edges (direct `call`/`bl`).
* **Indirect calls** via GOT/IAT, vtables, function pointers (approximate with points‑to sets).
* Tailcalls, thunks, PLT interposition.
4. **Call‑graph build**
* Start from **entrypoints**:
* ELF entry (`_start`), constructors (`.init_array`), exported API (public symbols), `main` (if recoverable).
* Optional: **entry‑trace** (cmd‑line + env + loader path) from container image to seed realistic roots.
* Build **CG** with:
* Direct edges: precise.
* Indirect edges: conservative, with **evidence tags** (GOT target set, vtable class set, signature match).
* Record **inter‑module edges** to shared libs (soname + version) with relocation evidence.
5. **Reachability scoring (deterministic)**
* Input: list of vulnerable functions/paths (from CSAF/CVE KB) normalized to **function‑level identifiers** (soname!symbol or hash‑based if unnamed).
* Compute **reachability** from roots → target:
* `REACHABLE_CONFIRMED` (path with only precise edges),
* `REACHABLE_POSSIBLE` (path contains conservative edges),
* `NOT_REACHABLE_FOUNDATION` (no path in current graph),
* Add **confidence** derived from edge evidence + relocation proof.
* Emit **proof trails** (the exact path: nodes, edges, evidence).
6. **Neutral JSON intermediate (NJIF)**
* Stored in cache; signed for deterministic replay.
* Consumed by StellaOps.Policy/Lattice to merge with VEX.

# Practical extractors (headless/CLI)
* **DWARF**: `llvm-dwarfdump`/`eu-readelf` for quick CU/function ranges; fall back to the disassembler.
* **Disassembly/CFG/CG** (choose one or more; wrap with a stable adapter):
* **Ghidra Headless API**: recover functions, basic blocks, references, PLT/GOT, vtables; export via a custom headless script to NJIF.
* **radare2 / rizin**: `aaa`, `agCd`, `aflj`, `agj` to export functions/graphs as JSON.
* **Binary Ninja headless** (if license permits) for cleaner IL and indirect‑call modeling.
* **angr** for path‑sensitive refinement on tricky indirect calls (optional, gated by budget).
**Adapter principle:** All tools output a **small, consistent NJIF** so the scoring engine and lattice logic never depend on any single RE tool.
---
# Indirect call modeling (concise rules)
* **PLT/GOT**: edge from caller → `soname!symbol` with evidence: `plt`, `reloc@GOT`.
* **Function pointers**: if a store to a pointer is found and targets a known function set `{f1…fk}`, add edges with `kind: "indirect"`, `evidence: ["xref-store", "sig-compatible"]`.
* **Virtual calls / vtables**: class‑method set from RTTI/vtable scans; mark edges `evidence: ["vtable-match"]`.
* **Tailcalls**: treat as edges, not fallthrough.
Each conservative step lowers **confidence**, but keeps determinism: the rules and their hashes are in the scan manifest.
---
# Deterministic scoring (plug into Stella’s lattice)
* **Inputs**: NJIF, CVE→function mapping (`soname!symbol` or function hash), policy knobs.
* **States**: `{NOT_OBSERVED < POSSIBLE < REACHABLE_CONFIRMED}` with **monotone** merge (never oscillates).
* **Confidence**: product of edge evidences (configurable weights): `direct=1.0, plt=0.98, vtable=0.85, funcptr=0.7`.
* **Output**: OpenVEX/CSAF annotations + human proof path; signed with DSSE to preserve replayability.
---
# Minimal Ghidra headless skeleton (exporter idea)
```bash
analyzeHeadless /work/gh_proj MyProj -import app -scriptPath scripts \
-postScript ExportNjif.java /out/app.njif.json
```
```java
// ExportNjif.java (outline)
public class ExportNjif extends GhidraScript {
public void run() throws Exception {
var fns = getFunctions(true);
// collect functions, blocks, calls, externs/PLT
// map non‑named functions to sub_<addr>
// detect PLT thunks → dynsym names
// write NJIF JSON deterministically (sorted keys, stable ordering)
}
}
```
---
# Integration points in StellaOps
* **Scanner.Analyzers.Binary.Elf**
* `ElfNormalizer` → hashes, dynamic deps.
* `Symbolizer` → DWARF reader + HeuristicDisasm (via tool adapter).
* `CgBuilder` → NJIF builder/merger (multi‑module).
* `ReachabilityEngine` → path search + confidence math.
* `Emitter` → NJIF cache + VEX/CSAF notes.
* **Scheduler**: memoize by `(hashes, toolchain_version, ruleset_hash)` to ensure replayable results.
* **Authority**: sign NJIF + scoring outputs; store manifests (feeds, rule weights, tool versions).
---
# Test fixtures (suggested)
* Tiny ELF zoo: statically linked, PIE, stripped/non‑stripped, C++ with vtables, musl vs glibc.
* Known CVE libs (e.g., `libssl`, `zlib`) with versioned symbols to validate soname!symbol mapping.
* Synthetic binaries with function‑pointer tables to validate conservative edges.
---
If you want, I can generate:
* A ready‑to‑run **Ghidra headless exporter** (Java) that writes NJIF exactly like above.
* A small **.NET parser** that ingests NJIF and emits StellaOps reachability + OpenVEX notes.
Below is a full architecture plan for implementing **stripped-ELF binary reachability** (call graph + NJIF + deterministic scoring, with a hook for patch-oracles) inside **StellaOps**.
I will assume .NET 10, existing microservice split (Scanner.WebService, Scanner.Worker, Concelier, Excitior, Authority, Scheduler, Sbomer, Signals), and your standing rule: **all lattice logic runs in Scanner.WebService**.
---
## 1. Scope, Objectives, Non-Goals
### 1.1 Objectives
1. **Recover function-level call graphs from ELF binaries**, including **stripped** ones:
* Support ET_EXEC / ET_DYN / PIE, static & dynamic linking.
* Support at least **x86_64, aarch64** in v1, later armhf, riscv64.
2. **Produce a neutral, deterministic JSON representation (NJIF)**:
* Tool-agnostic: can be generated from Ghidra, radare2/rizin, Binary Ninja, angr, etc.
* Stable identifiers and schema so downstream services don’t depend on a specific RE engine.
3. **Compute function-level reachability for vulnerabilities**:
* Given CVE → `soname!symbol` (and later function-hash) mappings from Concelier,
* Decide `REACHABLE_CONFIRMED` / `REACHABLE_POSSIBLE` / `NOT_REACHABLE_FOUNDATION` with evidence and confidence.
4. **Integrate with StellaOps lattice and VEX outputs**:
* Lattice logic runs in **Scanner.WebService**.
* Results flow into Excitior (VEX) and Sbomer (SBOM annotations), preserving provenance.
5. **Enable deterministic replay**:
* Every analysis run is tied to a **Scan Manifest**: tool versions, ruleset hashes, policy hashes, container image digests.
### 1.2 Non-Goals (v1)
* No dynamic runtime probes (EventPipe/JFR) in this phase.
* No full decompilation; we only need enough IR for calls/edges.
* No aggressive path-sensitive analysis (symbolic execution) in v1; that can be a v2 enhancement.
---
## 2. High-Level System Architecture
### 2.1 Components
* **Scanner.WebService (existing)**
* REST/gRPC API for scans.
* Orchestrates analysis jobs via Scheduler.
* Hosts **Lattice & Reachability Engine** for all artifact types.
* Reads NJIF results, merges with Concelier function mappings and policies.
* **Scanner.Worker (existing, extended)**
* Executes **Binary Analyzer Pipelines**.
* Invokes RE tools (Ghidra, rizin, etc.) in dedicated containers.
* Produces NJIF and persists it.
* **Binary Tools Containers (new)**
* `stellaops-tools-ghidra:<tag>`
* `stellaops-tools-rizin:<tag>`
* Optionally `stellaops-tools-angr` for advanced passes.
* Pinned versions, no network access (for determinism & air-gap).
* **Storage & Metadata**
* **DB (PostgreSQL)**: scan records, NJIF metadata, reachability summaries.
* **Object store** (MinIO/S3/Filesystem): NJIF JSON blobs, tool logs.
* **Authority**: DSSE signatures for Scan Manifest, NJIF, and reachability outputs.
* **Concelier**
* Provides **CVE → component → function symbol/hashes** resolution.
* Exposes “Link-Not-Merge” graph of advisory, component, and function nodes.
* **Excitior (VEX)**
* Consumes Scanner.WebService reachability states.
* Emits OpenVEX/CSAF with properly justified statuses.
* **UnknownsRegistry (future)**
* Receives unresolvable call edges / ambiguous functions from the analyzer,
* Feeds them into “adaptive security” workflows.
### 2.2 End-to-End Flow (Binary / Image Scan)
1. Client requests scan (binary or container image) via **Scanner.WebService**.
2. WebService:
* Extracts binaries from OCI layers (if scanning image),
* Registers **Scan Manifest**,
* Submits a job to Scheduler (queue: `binary-elfflow`).
3. Scanner.Worker dequeues the job:
* Detects ELF binaries,
* Runs **Binary Analyzer Pipeline** for each unique binary hash.
4. Worker uses tools containers:
* Ghidra/rizin → CFG, function discovery, call graph,
* Converts to **NJIF**.
5. Worker persists NJIF + metadata; marks analysis complete.
6. Scanner.WebService picks up NJIF:
* Fetches advisory function mappings from Concelier,
* Runs **Reachability & Lattice scoring**,
* Updates scan results and triggers Excitior / Sbomer.
All steps are deterministic given:
* Input artifact,
* Tool container digests,
* Ruleset/policy versions.
---
## 3. Binary Analyzer Subsystem (Scanner.Worker)
Introduce a dedicated module:
* `StellaOps.Scanner.Analyzers.Binary.Elf`
### 3.1 Internal Layers
1. **ElfDetector**
* Inspects files in a scan:
* Magic `0x7f 'E' 'L' 'F'`,
* Confirms architecture via ELF header.
* Produces `BinaryArtifact` records with:
* `hashes` (SHA-256, BLAKE3),
* `path` in container,
* `arch`, `endianness`.
2. **ElfNormalizer**
* Uses a lightweight library (e.g., ElfSharp) to extract:
* `ElfType` (ET_EXEC, ET_DYN),
* interpreter (`PT_INTERP`),
* `DT_NEEDED` list,
* RPATH/RUNPATH,
* presence/absence of DWARF sections.
* Emits a normalized `ElfMetadata` DTO.
3. **Symbolization Layer**
* Sub-components:
* `DwarfSymbolReader`: if DWARF present, read CU, function ranges, names, inlines.
* `DynsymReader`: parse `.dynsym`, `.plt`, exported symbols.
* `HeuristicFunctionFinder`:
* For stripped binaries:
* Use disassembler xrefs, prolog patterns, return instructions, call-targets.
* Recognize PLT thunks → `soname!symbol`.
* Consolidates into `FunctionSymbol` entities:
* `id` (e.g., `main`, `sub_401000`, `libc.so.6!memcpy`),
* `addr`, `size`, `is_external`, `from` (`dwarf`, `dynsym`, `heuristic`).
4. **Disassembly & IR Layer**
* Abstraction: `IDisassemblyAdapter`:
* `Task<DisasmResult> AnalyzeAsync(BinaryArtifact, ElfMetadata, ScanManifest)`
* Implementations:
* `GhidraDisassemblyAdapter`:
* Invokes headless Ghidra in container,
* Receives machine-readable JSON (script-produced),
* Extracts functions, basic blocks, calls, GOT/PLT info, vtables.
* `RizinDisassemblyAdapter` (backup/fallback).
* Produces:
* `BasicBlock` objects,
* `Instruction` metadata where needed for calls,
* `CallSite` records (direct, PLT, indirect).
5. **Call-Graph Builder**
* Consumes `FunctionSymbol` + `CallSite` sets.
* Identifies **roots**:
* `_start`, `.init_array` entries,
* `main` (if present),
* Exported API functions for shared libs.
* Creates `CallGraph`:
* Nodes: functions (`FunctionNode`),
* Edges: `CallEdge` with:
* `kind`: `direct`, `plt`, `indirect-funcptr`, `indirect-vtable`, `tailcall`,
* `evidence`: tags like `["reloc@GOT", "sig-match", "vtable-class"]`.
6. **Evidence & Confidence Annotator**
* For each edge, computes a **local confidence**:
* `direct`: 1.0
* `plt`: 0.98
* `indirect-funcptr`: 0.7
* `indirect-vtable`: 0.85
* For each path later, Scanner.WebService composes these.
7. **NJIF Serializer**
* Transforms domain objects into **NJIF JSON**:
* Sorted keys, stable ordering for determinism.
* Writes:
* `artifact`, `elf`, `symbols`, `cfg`, `cg`, and partial `reachability: []` (filled by WebService).
* Stores in object store, returns location + hash to DB.
8. **Unknowns Reporting**
* Any unresolved:
* Indirect call with empty target set,
* Function region not mapped to symbol,
* Logged as `UnknownEvidence` records and optionally published to **UnknownsRegistry** stream.
---
## 4. NJIF Data Model (Neutral JSON Intermediate Format)
Define a stable schema with a top-level `njif_schema_version` field.
### 4.1 Top-Level Shape
```json
{
"njif_schema_version": "1.0.0",
"artifact": { ... },
"symbols": { ... },
"cfg": [ ... ],
"cg": { ... },
"reachability": [ ... ],
"provenance": { ... }
}
```
### 4.2 Key Sections
1. `artifact`
* `path`, `hashes`, `arch`, `elf.type`, `interpreter`, `needed`, `rpath`, `runpath`.
2. `symbols`
* `exported`: external/dynamic symbols, especially PLT:
* `id`, `kind`, `plt`, `lib`.
* `functions`:
* `id` (synthetic or real name),
* `addr`, `size`, `from` (source of naming info),
* `name_hint` (optional).
3. `cfg`
* Per-function basic block CFG plus call sites:
* Blocks with `succ`, `calls` entries.
* Sufficient for future static checks, not full IR.
4. `cg`
* `nodes`: function nodes with evidence tags.
* `edges`: call edges with:
* `from`, `to`, `kind`, `evidence`.
* `roots`: entrypoints for reachability algorithms.
5. `reachability`
* Initially empty from Worker.
* Populated in Scanner.WebService as:
```json
{
"target": "libssl.so.3!SSL_free",
"status": "REACHABLE_CONFIRMED",
"path": ["_start", "main", "libssl.so.3!SSL_free"],
"confidence": 0.93,
"evidence": ["plt", "dynsym", "reloc"]
}
```
6. `provenance`
* `toolchain`:
* `disasm`: `"ghidra_headless:10.4"`, etc.
* `scan_manifest_hash`,
* `timestamp_utc`.
### 4.3 Persisting NJIF
* Object store (versioned path):
* `njif/{sha256}/njif-v1.json`
* DB table `binary_njif`:
* `binary_hash`, `njif_hash`, `schema_version`, `toolchain_digest`, `scan_manifest_id`.
---
## 5. Reachability & Lattice Integration (Scanner.WebService)
### 5.1 Inputs
* **NJIF** for each binary (possibly multiple binaries per container).
* Concelier’s **CVE → (component, function)** resolution:
* `component_id` → `soname!symbol` sets, and where available, function hashes.
* Scanner’s existing **lattice policies**:
* States: e.g. `NOT_OBSERVED < POSSIBLE < REACHABLE_CONFIRMED`.
* Merge rules are monotone.
### 5.2 Reachability Engine
New service module:
* `StellaOps.Scanner.Domain.Reachability`
* `INjifRepository` (reads NJIF JSON),
* `IFunctionMappingResolver` (Concelier adapter),
* `IReachabilityCalculator`.
Algorithm per target function:
1. Resolve vulnerable function(s):
* From Concelier: `soname!symbol` and/or `func_hash`.
* Map to NJIF `symbols.exported` or `symbols.functions`.
2. For each binary:
* Use `cg.roots` as entry set.
* BFS/DFS along edges until:
* Reaching target node(s),
* Or graph fully explored.
3. For each successful path:
* Collect edges’ `confidence` weights, compute path confidence:
* e.g., product of edge confidences or a log/additive scheme.
4. Aggregate result:
* If ≥ 1 path with only `direct/plt` edges:
* `status = REACHABLE_CONFIRMED`.
* Else if only paths with indirect edges:
* `status = REACHABLE_POSSIBLE`.
* Else:
* `status = NOT_REACHABLE_FOUNDATION`.
5. Emit `reachability` entry back into NJIF (or as separate DB table) and into scan result graph.
### 5.3 Lattice & VEX
* Lattice computation is done per `(CVE, component, binary)` triple:
* Input: reachability status + other signals.
* Resulting state is:
* Exposed to **Excitior** as a set of **evidence-annotated VEX facts**.
* Excitior translates:
* `NOT_REACHABLE_FOUNDATION` → likely `not_affected` with justification “code_not_reachable”.
* `REACHABLE_CONFIRMED` → `affected` or “present_and_exploitable” (depending on overall policy).
---
## 6. Patch-Oracle Extension (Advanced, but Architected Now)
While not strictly required for v1, we should reserve architecture hooks.
### 6.1 Concept
* Given:
* A **vulnerable** library build (or binary),
* A **patched** build.
* Run analyzers on both; produce NJIF for each.
* Compare call graphs & function bodies (e.g., hash of normalized bytes):
* Identify **changed functions** and potentially changed code regions.
* Concelier links those function IDs to specific CVEs (via vendor patch metadata).
* These become authoritative “patched function sets” (the **patch oracle**).
### 6.2 Integration Points
Add a module:
* `StellaOps.Scanner.Analysis.PatchOracle`
* Input: pair of artifact hashes (old, new) + NJIF.
* Output: list of `FunctionPatchRecord`:
* `function_id`, `binary_hash_old`, `binary_hash_new`, `change_kind` (`added`, `modified`, `deleted`).
Concelier:
* Ingests `FunctionPatchRecord` via internal API and updates advisory graph:
* CVE → function set derived from real patch.
* Reachability Engine:
* Uses patch-derived function sets instead of or in addition to symbol mapping from vendor docs.
---
## 7. Persistence, Determinism, Caching
### 7.1 Scan Manifest
For every scan job, create:
* `scan_manifest`:
* Input artifact hashes,
* List of binaries,
* Tool container digests (Ghidra, rizin, etc.),
* Ruleset/policy/lattice hashes,
* Time, user, and config flags.
Authority signs this manifest with DSSE.
### 7.2 Binary Analysis Cache
Key: `(binary_hash, arch, toolchain_digest, njif_schema_version)`.
* If present:
* Skip re-running Ghidra/rizin; reuse NJIF.
* If absent:
* Run analysis, then cache NJIF.
This provides deterministic replay and prevents re-analysis across scans and across customers (if allowed by tenancy model).
---
## 8. APIs & Integration Contracts
### 8.1 Scanner.WebService External API (REST)
1. `POST /api/scans/images`
* Existing; extended to flag: `includeBinaryReachability: true`.
2. `POST /api/scans/binaries`
* Upload a standalone ELF; returns `scan_id`.
3. `GET /api/scans/{scanId}/reachability`
* Returns list of `(cve_id, component, binary_path, function_id, status, confidence, path)`.
No path versioning; idempotent and additive (new fields appear, old ones remain valid).
### 8.2 Internal APIs
* **Worker ↔ Object Store**:
* `PUT /binary-njif/{sha256}/njif-v1.json`.
* **WebService ↔ Worker (via Scheduler)**:
* Job payload includes:
* `scan_manifest_id`,
* `binary_hashes`,
* `analysis_profile` (`default`, `deep`).
* **WebService ↔ Concelier**:
* `POST /internal/functions/resolve`:
* Input: `(cve_id, component_ids[])`,
* Output: `soname!symbol[]`, optional `func_hash[]`.
* **WebService ↔ Excitior**:
* Existing VEX ingestion extended with **reachability evidence** fields.
---
## 9. Observability, Security, Resource Model
### 9.1 Observability
* **Metrics**:
* Analysis duration per binary,
* NJIF size,
* Cache hit ratio,
* Reachability evaluation time per CVE.
* **Logs**:
* Ghidra/rizin container logs stored alongside NJIF,
* Unknowns logs for unresolved call targets.
* **Tracing**:
* Each scan/analysis annotated with `scan_manifest_id` to allow end-to-end trace.
### 9.2 Security
* Tools containers:
* No outbound network.
* Limited to read-only artifact mount + write-only result mount.
* Binary content:
* Treated as confidential; stored encrypted at rest if your global policy requires it.
* DSSE:
* Authority signs:
* Scan Manifest,
* NJIF blob hash,
* Reachability summary.
* Enables “Proof-of-Integrity Graph” linkage later.
### 9.3 Resource Model
* ELF analysis can be heavy; design for:
* Separate **worker queue** and autoscaling group for binary analysis.
* Configurable max concurrency and per-job CPU/memory limits.
* Deep analysis (indirect calls, vtables) can be toggled via `analysis_profile`.
---
## 10. Implementation Roadmap
A pragmatic, staged plan:
### Phase 0 – Foundations (1–2 sprints)
* Create `StellaOps.Scanner.Analyzers.Binary.Elf` project.
* Implement:
* `ElfDetector`, `ElfNormalizer`.
* DB tables: `binary_artifacts`, `binary_njif`.
* Integrate with Scheduler and Worker pipeline.
### Phase 1 – Non-stripped ELF + NJIF v1 (2–3 sprints)
* Implement **DWARF + dynsym symbolization**.
* Implement **GhidraDisassemblyAdapter** for x86_64.
* Build **CallGraphBuilder** (direct + PLT calls).
* Implement NJIF serializer v1; store in object store.
* Basic reachability engine in WebService:
* Only direct and PLT edges,
* Only for DWARF-named functions.
* Integrate with Concelier function mapping via `soname!symbol`.
### Phase 2 – Stripped ELF Support (2–3 sprints)
* Implement `HeuristicFunctionFinder` for function discovery in stripped binaries.
* Extend Ghidra script to mark PLT/GOT, vtables, function pointers.
* Call graph: add:
* `indirect-funcptr`, `indirect-vtable`, `tailcall` edges.
* Evidence tagging and local confidence scoring.
* Extend reachability engine to:
* Distinguish `REACHABLE_CONFIRMED` vs `REACHABLE_POSSIBLE`.
### Phase 3 – Multi-Arch & Performance (2–3 sprints)
* Add support for **aarch64** (Ghidra language, appropriate calling conventions).
* Optimize:
* Binary analysis cache,
* Tool container lifecycle,
* Concurrent analysis.
* Add Unknowns reporting and hookup to UnknownsRegistry (if already implemented).
### Phase 4 – Patch-Oracle Pilot (2–3 sprints)
* Implement PatchOracle module:
* Compare old/new NJIFs,
* Detect changed functions.
* Integrate with Concelier’s advisory graph.
* Start validating against curated CVE/patch datasets.
### Phase 5 – Hardening & Documentation
* Golden fixtures:
* Small ELF zoo (stripped/non-stripped, PIE, static, C++, vtables).
* Known vulnerable libs (e.g., OpenSSL, zlib) to confirm correct function mapping.
* Add CLI/demo in `StellaOps.Scanner.Cli`:
* `stellaops scan-binary --file app --show-reachability`.
* Customer-facing and internal docs:
* NJIF schema,
* API usage,
* Limitations and interpretation guidelines.
---
If you want, next step I can do is take this plan and:
* Break it into **epics / tickets** (SCAN-BINARY-xxx) with clear DoD per phase, or
* Draft the **Ghidra headless Java script** and the **.NET NJIF model classes** so your agents can plug them straight into the Scanner repo.

Vlad, here’s a concrete, **pure‑C#** blueprint to build a multi‑format binary analyzer (Mach‑O, ELF, PE) that produces **call graphs + reachability**, with **no external tools**. Where needed, I point to permissively‑licensed code you can **port** (copy) from other ecosystems.

## 0) Targets & non‑negotiables
* **Formats:** Mach‑O (inc. LC_DYLD_INFO / LC_DYLD_CHAINED_FIXUPS), ELF (SysV gABI), PE/COFF
* **Architectures:** x86‑64 (and x86), AArch64 (ARM64)
* **Outputs:** JSON with **purls** per module + function‑level call graph & reachability
* **No tool reuse:** Only pure C# libraries or code **ported** from permissive sources
---
## 1) Parsing the containers (pure C#)
**Pick one C# reader per format, keeping licenses permissive:**
* **ELF & Mach‑O:** `ELFSharp` (pure managed C#; ELF + Mach‑O reading). MIT/X11 license. ([GitHub][1])
* **ELF & PE (+ DWARF v4):** `LibObjectFile` (C#, BSD‑2). Good ELF relocations (i386, x86_64, ARM, AArch64), PE directories, DWARF sections. Use it as your **common object model** for ELF+PE, then add a Mach‑O adapter. ([GitHub][2])
* **PE (optional alternative):** `PeNet` (pure C#, broad PE directories, imp/exp, TLS, certs). MIT. Useful if you want a second implementation for cross‑checks. ([GitHub][3])
> Why two libs? `LibObjectFile` gives you DWARF and clean models for ELF/PE; `ELFSharp` covers Mach‑O today (and ELF as a fallback). You control the code paths.
**Spec references you’ll implement against** (for correctness of your readers & link‑time semantics):
* **ELF (gABI, AMD64 supplement):** dynamic section, PLT/GOT, `R_X86_64_JUMP_SLOT` semantics (eager vs lazy). ([refspecs.linuxbase.org][4])
* **PE/COFF:** imports/exports/IAT, delay‑load, TLS. ([Microsoft Learn][5])
* **Mach‑O:** file layout, load commands (`LC_SYMTAB`, `LC_DYSYMTAB`, `LC_FUNCTION_STARTS`, `LC_DYLD_INFO(_ONLY)`), and the modern `LC_DYLD_CHAINED_FIXUPS`. ([leopard-adc.pepas.com][6])
---
## 2) Mach‑O: what you must **port** (byte‑for‑byte compatible)
Apple moved from traditional dyld bind opcodes to **chained fixups** on macOS 12/iOS 15+; you need both:
* **Dyld bind opcodes** (`LC_DYLD_INFO(_ONLY)`): parse the BIND/LAZY_BIND streams (tuples of `<seg,off,type,ordinal,symbol,addend>`). Port minimal logic from **LLVM** or **LIEF** (both Apache‑2.0‑compatible) into C#. ([LIEF][7])
* **Chained fixups** (`LC_DYLD_CHAINED_FIXUPS`): port `dyld_chained_fixups_header` structs & chain walking from LLVM’s `MachO.h` or Apple’s dyld headers. This restores imports/rebases without running dyld. ([LLVM][8])
* **Function discovery hint:** read `LC_FUNCTION_STARTS` (ULEB128 deltas) to seed function boundaries—very helpful on stripped binaries. ([Stack Overflow][9])
* **Stubs mapping:** resolve `__TEXT,__stubs` ↔ `__DATA,__la_symbol_ptr` via the **indirect symbol table**; conceptually identical to ELF’s PLT/GOT. ([MaskRay][10])
> If you prefer an in‑C# base for Mach‑O manipulation, **Melanzana.MachO** exists (MIT) and has been used by .NET folks for Mach‑O/Code Signing/obj writing; you can mine its approach for load‑command modeling. ([GitHub][11])
---
## 3) Disassembly (pure C#, multi‑arch)
* **x86/x64:** `iced` (C# decoder/disassembler/encoder; MIT; fast & complete). ([GitHub][12])
* **AArch64/ARM64:** two options that keep you pure‑C#:
* **Disarm** (pure C# ARM64 disassembler; MIT). Good starting point to decode & get branch/call kinds. ([GitHub][13])
* **Port from Ryujinx ARMeilleure** (ARMv8 decoder/JIT in C#, MIT). You can lift only the **decoder** pieces you need. ([Gitee][14])
* **x86 fallback:** `SharpDisasm` (udis86 port in C#; BSD‑2). Older than iced; keep as a reference. ([GitHub][15])
---
## 4) Call graph recovery (static)
**4.1 Function seeds**
* From symbols (`.dynsym`/`LC_SYMTAB`/PE exports)
* From **LC_FUNCTION_STARTS** (Mach‑O) for stripped code ([Stack Overflow][9])
* From entrypoints (`_start`/`main` or PE AddressOfEntryPoint)
* From exception/unwind tables & DWARF (when present)—`LibObjectFile` already models DWARF v4. ([GitHub][2])
**4.2 CFG & interprocedural calls**
* **Decode** with iced/Disarm from each seed; form **basic blocks** by following control‑flow until terminators (ret/jmp/call).
* **Direct calls:** immediate targets become edges (PC‑relative fixups where needed).
* **Imported calls:**
* **ELF:** calls to PLT stubs → resolve via `.rela.plt` & `R_*_JUMP_SLOT` to symbol names (link‑time target). ([cs61.seas.harvard.edu][16])
* **PE:** calls through the **IAT** → resolve via `IMAGE_IMPORT_DESCRIPTOR` / thunk tables. ([Microsoft Learn][5])
* **Mach‑O:** calls to `__stubs` use **indirect symbol table** + `__la_symbol_ptr` (or chained fixups) → map to dylib/symbol. ([reinterpretcast.com][17])
* **Indirect calls within the binary:** heuristics only (function pointer tables, vtables, small constant pools). Keep them labeled **“indirect‑unresolved”** unless a heuristic yields a concrete target.
**4.3 Cross‑binary graph**
* Build module‑level edges by simulating the platform’s loader:
* **ELF:** honor `DT_NEEDED`, `DT_RPATH/RUNPATH`, versioning (`.gnu.version*`) to pick the definer of an imported symbol. gABI rules apply. ([refspecs.linuxbase.org][4])
* **PE:** pick DLL from the import descriptors. ([Microsoft Learn][5])
* **Mach‑O:** `LC_LOAD_DYLIB` + dyld binding / chained fixups determine the provider image. ([LIEF][7])
---
## 5) Reachability analysis
Represent the **call graph** using a .NET graph lib (or a simple adjacency set). I suggest:
* **QuikGraph** (successor of QuickGraph; MIT) for algorithms (DFS/BFS, SCCs). Use it to compute reachability from chosen roots (entrypoint(s), exported APIs, or “sinks”). ([GitHub][18])
You can visualize with **MSAGL** (MIT) when you need layouts, but your core output is JSON. ([GitHub][19])
---
## 6) Symbol demangling (nice‑to‑have, pure C#)
* **Itanium (ELF/Mach‑O):** Either port LLVM’s Itanium demangler or use a C# lib like **CxxDemangler** (a C# rewrite of `cpp_demangle`). ([LLVM][20])
* **MSVC (PE):** Port LLVM’s `MicrosoftDemangle.cpp` (Apache‑2.0 with LLVM exception) to C#. ([LLVM][21])
---
## 7) JSON output (with purls)
Use a stable schema (example) to feed SBOM/vuln matching downstream:
```json
{
"modules": [
{
"purl": "pkg:deb/ubuntu/openssl@1.1.1w-0ubuntu1?arch=amd64",
"format": "ELF",
"arch": "x86_64",
"path": "/usr/lib/x86_64-linux-gnu/libssl.so.1.1",
"exports": ["SSL_read", "SSL_write"],
"imports": ["BIO_new", "EVP_CipherInit_ex"],
"functions": [{"name":"SSL_do_handshake","va":"0x401020","size":512,"demangled": "..."}]
}
],
"graph": {
"nodes": [
{"id":"bin:main@0x401000","module": "pkg:generic/myapp@1.0.0"},
{"id":"lib:SSL_read","module":"pkg:deb/ubuntu/openssl@1.1.1w-0ubuntu1?arch=amd64"}
],
"edges": [
{"src":"bin:main@0x401000","dst":"lib:SSL_read","kind":"import_call","evidence":"ELF.R_X86_64_JUMP_SLOT"}
]
},
"reachability": {
"roots": ["bin:_start","bin:main@0x401000"],
"reachable": ["lib:SSL_read", "lib:SSL_write"],
"unresolved_indirect_calls": [
{"site":"0x402ABC","reason":"register-indirect"}
]
}
}
```
---
## 8) Minimal C# module layout (sketch)
```
Stella.Analysis.Core/
BinaryModule.cs // common model (sections, symbols, relocs, imports/exports)
Loader/
PeLoader.cs // wrap LibObjectFile (or PeNet) to BinaryModule
ElfLoader.cs // wrap LibObjectFile to BinaryModule
MachOLoader.cs // wrap ELFSharp + your ported Dyld/ChainedFixups
Disasm/
X86Disassembler.cs // iced bridge: bytes -> instructions
Arm64Disassembler.cs // Disarm (or ARMeilleure port) bridge
Graph/
CallGraphBuilder.cs // builds CFG per function + inter-procedural edges
Reachability.cs // BFS/DFS over QuikGraph
Demangle/
ItaniumDemangler.cs // port or wrap CxxDemangler
MicrosoftDemangler.cs // port from LLVM
Export/
JsonWriter.cs // writes schema above
```
---
## 9) Implementation notes (where issues usually bite)
* **Mach‑O moderns:** Implement both dyld opcode **and** chained fixups; many macOS 12+/iOS15+ binaries only have chained fixups. ([emergetools.com][22])
* **Stubs vs real targets (Mach‑O):** map `__stubs` → `__la_symbol_ptr` via **indirect symbols** to the true imported symbol (or its post‑fixup target). ([reinterpretcast.com][17])
* **ELF PLT/GOT:** treat `.plt` entries as **call trampolines**; ultimate edge should point to the symbol (library) that satisfies `DT_NEEDED` + version. ([refspecs.linuxbase.org][4])
* **PE delay‑load:** don’t forget `IMAGE_DELAYLOAD_DESCRIPTOR` for delayed IATs. ([Microsoft Learn][5])
* **Function discovery:** use `LC_FUNCTION_STARTS` when symbols are stripped; it’s a cheap way to seed analysis. ([Stack Overflow][9])
* **Name clarity:** demangle Itanium/MSVC so downstream vuln rules can match consistently. ([LLVM][20])
---
## 10) What to **copy/port** verbatim (safe licenses)
* **Dyld bind & exports trie logic:** from **LLVM** or **LIEF** Mach‑O (Apache‑2.0). Great for getting the exact opcode semantics right. ([LIEF][7])
* **Chained fixups structs/walkers:** from **LLVM MachO.h** or Apple dyld headers (permissive headers). ([LLVM][8])
* **Itanium/MS demanglers:** LLVM demangler sources are standalone; easy to translate to C#. ([LLVM][23])
* **ARM64 decoder:** if Disarm gaps hurt, lift just the **decoder** pieces from **Ryujinx ARMeilleure** (MIT). ([Gitee][14])
*(Avoid GPL’d parsers like binutils/BFD; they will contaminate your codebase’s licensing.)*
---
## 11) End‑to‑end pipeline (per container image)
1. **Enumerate binaries** in the container FS.
2. **Parse** each with the appropriate loader → `BinaryModule` (+ imports/exports/symbols/relocs).
3. **Simulate linking** per platform to resolve imported functions to provider libraries. ([refspecs.linuxbase.org][4])
4. **Disassemble** functions (iced/Disarm) → CFGs → **call edges** (direct, PLT/IAT/stub, indirect).
5. **Assemble call graph** across modules; normalize names via demangling.
6. **Reachability**: given roots (entry or user‑specified) compute reachable set; emit JSON with **purls** (from your SBOM/package resolver).
7. **(Optional)** dump GraphViz / MSAGL views for debugging. ([GitHub][19])
---
## 12) Quick heuristics for vulnerability triage
* **Sink maps**: flag edges to high‑risk APIs (`strcpy`, `gets`, legacy SSL ciphers) even without CVE versioning.
* **DWARF line info** (when present): attach file:line to nodes for developer action. `LibObjectFile` gives you DWARF v4 reads. ([GitHub][2])
---
## 13) Test corpora
* **ELF:** glibc/openssl/libpng from distro repos; validate `R_*_JUMP_SLOT` handling and PLT edges. ([cs61.seas.harvard.edu][16])
* **PE:** system DLLs (Kernel32, Advapi32) and a small MSVC console app; validate IAT & delay‑load. ([Microsoft Learn][5])
* **Mach‑O:** Xcode‑built binaries across macOS 11 & 12+ to cover both dyld opcode and chained fixups paths; verify `LC_FUNCTION_STARTS` improves discovery. ([Stack Overflow][9])
---
## 14) Deliverables you can start coding now
* **MachOLoader.cs**
* Parse headers + load commands (ELFSharp).
* Implement `DyldInfoParser` (port from LLVM/LIEF) and `ChainedFixupsParser` (port structs & walkers). ([LIEF][7])
* **X86Disassembler.cs / Arm64Disassembler.cs** (iced / Disarm bridges). ([GitHub][12])
* **CallGraphBuilder.cs** (recursive descent + linear sweep fallback; PLT/IAT/stub resolution).
* **Reachability.cs** (QuikGraph BFS/DFS). ([GitHub][18])
* **JsonWriter.cs** (schema above with purls).
---

Good, this is exactly the point where you want to nail the internal model, otherwise everything on top (VEX, policy, reporting) will be shaky.
Below is a detailed, implementation-ready plan for a **reachability graph with purl-aware edges**, covering ELF, PE, and Mach-O, in C#.
I’ll structure it as:
1. Overall graph design (3 layers: function, module, purl)
2. Core C# data model
3. Pipeline steps (end-to-end)
4. Format-specific edge construction (ELF / PE / Mach-O)
5. Reachability queries (from entrypoints to vulnerable purls / functions)
6. JSON output layout and integration with SBOM
---
## 1. Overall graph design
You want three tightly linked graph layers:
1. **Function-level call graph (FLG)**
* Nodes: individual **functions** inside binaries
* Edges: calls from function A → function B (intra- or inter-module)
2. **Module-level graph (MLG)**
* Nodes: **binaries** (ELF/PE/Mach-O files)
* Edges: “module A calls module B at least once” (aggregated from FLG)
3. **Purl-level graph (PLG)**
* Nodes: **purls** (packages or generic artifacts)
* Edges: “purl P1 depends-at-runtime on purl P2” (aggregated from module edges)
The **reachability algorithm** runs primarily on the **function graph**, but:
* You can project reachability results to **module** and **purl** nodes.
* You can also run coarse-grained analysis directly on **purl graph** when needed (“Is any code in purl X reachable from the container entrypoint?”).
---
## 2. Core C# data model
### 2.1 Identifiers and enums
```csharp
public enum BinaryFormat { Elf, Pe, MachO }
public readonly record struct ModuleId(string Path, BinaryFormat Format);
public readonly record struct Purl(string Value);
public enum EdgeKind
{
IntraModuleDirect, // call foo -> bar in same module
ImportCall, // call via plt/iat/stub to imported function
SyntheticRoot, // root (entrypoint) edge
IndirectUnresolved // optional: we saw an indirect call we couldn't resolve
}
```
### 2.2 Function node
```csharp
public sealed class FunctionNode
{
public int Id { get; init; } // internal numeric id
public ModuleId Module { get; init; }
public Purl Purl { get; init; } // resolved from Module -> Purl
public ulong Address { get; init; } // VA or RVA
public string Name { get; init; } // mangled
public string? DemangledName { get; init; } // optional
public bool IsExported { get; init; }
public bool IsImportedStub { get; init; } // e.g. PLT stub, Mach-O stub, PE thunks
public bool IsRoot { get; set; } // _start/main/entrypoint etc.
}
```
### 2.3 Edges
```csharp
public sealed class CallEdge
{
public int FromId { get; init; } // FunctionNode.Id
public int ToId { get; init; } // FunctionNode.Id
public EdgeKind Kind { get; init; }
public string Evidence { get; init; } // e.g. "ELF.R_X86_64_JUMP_SLOT", "PE.IAT", "MachO.indirectSym"
}
```
### 2.4 Graph container
```csharp
public sealed class CallGraph
{
public IReadOnlyDictionary<int, FunctionNode> Nodes { get; init; }
public IReadOnlyDictionary<int, List<CallEdge>> OutEdges { get; init; }
public IReadOnlyDictionary<int, List<CallEdge>> InEdges { get; init; }
// Convenience: mappings
public IReadOnlyDictionary<ModuleId, List<int>> FunctionsByModule { get; init; }
public IReadOnlyDictionary<Purl, List<int>> FunctionsByPurl { get; init; }
}
```
### 2.5 Purl-level graph view
You don’t store a separate physical graph; you **derive** it on demand:
```csharp
public sealed class PurlEdge
{
public Purl From { get; init; }
public Purl To { get; init; }
public List<(int FromFnId, int ToFnId)> SupportingCalls { get; init; }
}
public sealed class PurlGraphView
{
public IReadOnlyDictionary<Purl, HashSet<Purl>> Adjacent { get; init; }
public IReadOnlyList<PurlEdge> Edges { get; init; }
}
```
---
## 3. Pipeline steps (end-to-end)
### Step 0 – Inputs
* Set of binaries (files) extracted from container image.
* SBOM or other metadata that can map a file path (or hash) → **purl**.
### Step 1 – Parse binaries → `BinaryModule` objects
You define a common in-memory model:
```csharp
public sealed class BinaryModule
{
public ModuleId Id { get; init; }
public Purl Purl { get; init; }
public BinaryFormat Format { get; init; }
// Raw sections / segments
public IReadOnlyList<SectionInfo> Sections { get; init; }
// Symbols
public IReadOnlyList<SymbolInfo> Symbols { get; init; } // imports + exports + locals
// Relocations / fixups
public IReadOnlyList<RelocationInfo> Relocations { get; init; }
// Import/export tables (PE)/dylib commands (Mach-O)/DT_NEEDED (ELF)
public ImportInfo[] Imports { get; init; }
public ExportInfo[] Exports { get; init; }
}
```
Implement format-specific loaders:
* `ElfLoader : IBinaryLoader`
* `PeLoader : IBinaryLoader`
* `MachOLoader : IBinaryLoader`
Each loader uses your chosen C# parsers or ported code and fills `BinaryModule`.
### Step 2 – Disassembly → basic blocks & candidate functions
For each `BinaryModule`:
1. Use appropriate decoder (iced for x86/x64; Disarm/ported ARMeilleure for AArch64).
2. Seed function starts:
* Exported functions
* Entry points (`_start`, `main`, AddressOfEntryPoint)
* Mach-O `LC_FUNCTION_STARTS` if available
3. Walk instructions to build basic blocks:
* Stop blocks at conditional/unconditional branches, calls, rets.
* Record for each call site:
* Address of caller function
* Operand type (immediate, memory with import table address, etc.)
Disassembler outputs a list of `FunctionNode` skeletons (no cross-module link yet) and a list of **raw call sites**:
```csharp
public sealed class RawCallSite
{
public int CallerFunctionId { get; init; }
public ulong InstructionAddress { get; init; }
public ulong? DirectTargetAddress { get; init; } // e.g. CALL 0x401000
public ulong? MemoryTargetAddress { get; init; } // e.g. CALL [0x404000]
public bool IsIndirect { get; init; } // register-based etc.
}
```
### Step 3 – Build function nodes
Using disassembly + symbol tables:
* For each discovered function:
* Determine: address, name (if sym available), export/import flags.
* Map `ModuleId` → `Purl` using `IPurlResolver`.
* Populate `FunctionNode` instances and index them by `Id`.
### Step 4 – Construct intra-module edges
For each `RawCallSite`:
* If `DirectTargetAddress` falls inside a known function’s address range in the **same module**, add **IntraModuleDirect** edge.
This gives you “normal” calls like `foo()` calling `bar()` in the same .so/.dll/.
### Step 5 – Construct inter-module edges (import calls)
This is where ELF/PE/Mach-O differ; details in section 4 below.
But the abstract logic is:
1. For each call site with `MemoryTargetAddress` (IAT slot / GOT entry / la_symbol_ptr / PLT):
2. From the module’s import, relocation or fixup tables, determine:
* Which **imported symbol** it corresponds to (name, ordinal, etc.).
* Which **imported module / dylib / DLL** provides that symbol.
3. Find (or create) a `FunctionNode` representing that imported symbol in the **provider module**.
4. Add an **ImportCall** edge from caller function to the provider `FunctionNode`.
This is the key to turning low-level dynamic linking into **purl-aware cross-module edges**, because each `FunctionNode` is already stamped with a `Purl`.
### Step 6 – Build adjacency structures
Once you have all `FunctionNode`s and `CallEdge`s:
* Build `OutEdges` and `InEdges` dictionaries keyed by `FunctionNode.Id`.
* Build `FunctionsByModule` / `FunctionsByPurl`.
---
## 4. Format-specific edge construction
This is the “how” for step 5, per binary format.
### 4.1 ELF
Goal: map call sites that go via PLT/GOT to an imported function in a `DT_NEEDED` library.
Algorithm:
1. Parse:
* `.dynsym`, `.dynstr` – dynamic symbol table
* `.rela.plt` / `.rel.plt` – relocation entries for PLT
* `.got.plt` / `.got` – PLT’s GOT
* `DT_NEEDED` entries – list of linked shared objects and their sonames
2. For each relocation of type `R_*_JUMP_SLOT`:
* It applies to an entry in the PLT GOT; that GOT entry is what CALL instructions read from.
* Relocation gives you:
* Offset in GOT (`r_offset`)
* Symbol index (`r_info` → symbol) → dynamic symbol (`ElfSymbol`)
* Symbol name, type (FUNC), binding, etc.
3. Link GOT entries to call sites:
* For each `RawCallSite` with `MemoryTargetAddress`, check if that address falls inside `.got.plt` (or `.got`). If it does:
* Find relocation whose `r_offset` equals that GOT entry offset.
* That tells you which **symbol** is being called.
4. Determine provider module:
* From the symbol’s `st_name` and `DT_NEEDED` list, decide which shared object is expected to define it (an approximation is: first DT_NEEDED that provides that name).
* Map DT_NEEDED → `ModuleId` (you’ll have loaded these modules separately, or you can create “placeholder modules” if they’re not in the container image).
5. Create edges:
* Create/find `FunctionNode` for the **imported symbol** in provider module.
* Add `CallEdge` from caller function to imported function, `EdgeKind = ImportCall`, `Evidence = "ELF.R_X86_64_JUMP_SLOT"` (or arch-specific).
This yields edges like:
* `myapp:main` → `libssl.so.1.1:SSL_read`
* `libfoo.so:foo` → `libc.so.6:malloc`
### 4.2 PE
Goal: map call sites that go via the Import Address Table (IAT) to imported functions in DLLs.
Algorithm:
1. Parse:
* `IMAGE_IMPORT_DESCRIPTOR[]` – each for a DLL name.
* Original thunk table (INT) – names/ordinals of imported symbols.
* IAT – where the loader writes function addresses at runtime.
2. For each import entry:
* Determine:
* DLL name (`Name`)
* Function name or ordinal (from INT)
* IAT slot address (RVA)
3. Link IAT slots to call sites:
* For each `RawCallSite` with `MemoryTargetAddress`:
* Check if this address equals the VA of an IAT slot.
* If yes, the call site is effectively calling that imported function.
4. Determine provider module:
* The DLL name gives you a target module (e.g. `KERNEL32.dll` → `ModuleId`).
* Ensure that DLL is represented as a `BinaryModule` or a “placeholder” if not present in image.
5. Create edges:
* Create/find `FunctionNode` for imported function in provider module.
* Add `CallEdge` with `EdgeKind = ImportCall` and `Evidence = "PE.IAT"` (or `"PE.DelayLoad"` if using delay load descriptors).
Example:
* `myservice.exe:Start` → `SSPICLI.dll:AcquireCredentialsHandleW`
### 4.3 Mach-O
Goal: map stub calls via `__TEXT,__stubs` / `__DATA,__la_symbol_ptr` (and / or chained fixups) to symbols in dependent dylibs.
Algorithm (for classic dyld opcodes, not chained fixups, then extend):
1. Parse:
* Load commands:
* `LC_SYMTAB`, `LC_DYSYMTAB`
* `LC_LOAD_DYLIB` (to know dependent dylibs)
* `LC_FUNCTION_STARTS` (for seeding functions)
* `LC_DYLD_INFO` (rebase/bind/lazy bind)
* `__TEXT,__stubs` – stub code
* `__DATA,__la_symbol_ptr` (or `__DATA_CONST,__la_symbol_ptr`) – lazy pointer table
* **Indirect symbol table** – maps slot indices to symbol table indices
2. Stub → la_symbol_ptr mapping:
* Stubs are small functions (usually a few instructions) that indirect through the corresponding `la_symbol_ptr` entry.
* For each stub function:
* Determine which la_symbol_ptr entry it uses (based on stub index and linking metadata).
* From the indirect symbol table, find which dynamic symbol that la_symbol_ptr entry corresponds to.
* This gives you symbol name and the index in `LC_LOAD_DYLIB` (dylib ordinal).
3. Link stub call sites:
* In disassembly, treat calls to these stub functions as **import calls**.
* For each call instruction `CALL stub_function`:
* `RawCallSite.DirectTargetAddress` lies inside `__TEXT,__stubs`.
* Resolve stub → la_symbol_ptr → symbol → dylib.
4. Determine provider module:
* From dylib ordinal and load commands, get the path / install name of dylib (`libssl.1.1.dylib`, etc.).
* Map that to a `ModuleId` in your module set.
5. Create edges:
* Create/find imported `FunctionNode` in provider module.
* Add `CallEdge` from caller to that function with `EdgeKind = ImportCall`, `Evidence = "MachO.IndirectSymbol"`.
For **chained fixups** (`LC_DYLD_CHAINED_FIXUPS`), you’ll compute a similar mapping but walking chain entries instead of traditional lazy/weak binds. The key is still:
* Map a stub or function to a **fixup** entry.
* From fixup, determine the symbol and dylib.
* Then connect call-site → imported function.
---
## 5. Reachability queries
Once the graph is built, reachability is “just graph algorithms” + mapping back to purls.
### 5.1 Roots
Decide what are your **root functions**:
* Binary entrypoints:
* ELF: `_start`, `main`, constructors (`.init_array`)
* PE: AddressOfEntryPoint, registered service entrypoints
* Mach-O: `_main`, constructors
* Optionally, any exported API function that a container orchestrator or plugin system will call.
Mark them as `FunctionNode.IsRoot = true` and create synthetic edges from a special root node if you want:
```csharp
var syntheticRoot = new FunctionNode
{
Id = 0,
Name = "<root>",
IsRoot = true,
// Module, Purl can be special markers
};
foreach (var fn in allFunctions.Where(f => f.IsRoot))
{
edges.Add(new CallEdge
{
FromId = syntheticRoot.Id,
ToId = fn.Id,
Kind = EdgeKind.SyntheticRoot,
Evidence = "Root"
});
}
```
### 5.2 Reachability algorithm (function-level)
Use BFS/DFS from the root node(s):
```csharp
public sealed class ReachabilityResult
{
public HashSet<int> ReachableFunctions { get; } = new();
}
public ReachabilityResult ComputeReachableFunctions(CallGraph graph, IEnumerable<int> rootIds)
{
var visited = new HashSet<int>();
var stack = new Stack<int>();
foreach (var root in rootIds)
{
if (visited.Add(root))
stack.Push(root);
}
while (stack.Count > 0)
{
var current = stack.Pop();
if (!graph.OutEdges.TryGetValue(current, out var edges))
continue;
foreach (var edge in edges)
{
if (visited.Add(edge.ToId))
stack.Push(edge.ToId);
}
}
return new ReachabilityResult { ReachableFunctions = visited };
}
```
### 5.3 Project reachability to modules and purls
Given `ReachableFunctions`:
```csharp
public sealed class ReachabilityProjection
{
public HashSet<ModuleId> ReachableModules { get; } = new();
public HashSet<Purl> ReachablePurls { get; } = new();
}
public ReachabilityProjection ProjectToModulesAndPurls(CallGraph graph, ReachabilityResult result)
{
var projection = new ReachabilityProjection();
foreach (var fnId in result.ReachableFunctions)
{
if (!graph.Nodes.TryGetValue(fnId, out var fn))
continue;
projection.ReachableModules.Add(fn.Module);
projection.ReachablePurls.Add(fn.Purl);
}
return projection;
}
```
Now you can answer questions like:
* “Is any code from purl `pkg:deb/openssl@1.1.1w-1` reachable from the container entrypoint?”
* “Which purls are reachable at all?”
### 5.4 Vulnerability reachability
Assume you’ve mapped each vulnerability to:
* `Purl` (where it lives)
* `AffectedFunctionNames` (symbols; optionally demangled)
You can implement:
```csharp
public sealed class VulnerabilitySink
{
public string VulnerabilityId { get; init; } // CVE-...
public Purl Purl { get; init; }
public string FunctionName { get; init; } // symbol name or demangled
}
```
Resolution algorithm:
1. For each `VulnerabilitySink`, find all `FunctionNode` with:
* `node.Purl == sink.Purl` and
* `node.Name` or `node.DemangledName` matches `sink.FunctionName`.
2. For each such node, check `ReachableFunctions.Contains(node.Id)`.
3. Build a `Finding` object:
```csharp
public sealed class VulnerabilityFinding
{
public string VulnerabilityId { get; init; }
public Purl Purl { get; init; }
public bool IsReachable { get; init; }
public List<int> SinkFunctionIds { get; init; } = new();
}
```
Plus, if you want **path evidence**, you run a shortest-path search (BFS predecessor map) from root to sink and store the sequence of `FunctionNode.Id`s.
---
## 6. Purl edges (derived graph)
For reporting and analytics, it’s useful to produce a **purl-level dependency graph**.
Given `CallGraph`:
```csharp
public PurlGraphView BuildPurlGraph(CallGraph graph)
{
var edgesByPair = new Dictionary<(Purl From, Purl To), PurlEdge>();
foreach (var kv in graph.OutEdges)
{
var fromFn = graph.Nodes[kv.Key];
foreach (var edge in kv.Value)
{
var toFn = graph.Nodes[edge.ToId];
if (fromFn.Purl.Equals(toFn.Purl))
continue; // intra-purl, skip if you only care about inter-purl
var key = (fromFn.Purl, toFn.Purl);
if (!edgesByPair.TryGetValue(key, out var pe))
{
pe = new PurlEdge
{
From = fromFn.Purl,
To = toFn.Purl,
SupportingCalls = new List<(int, int)>()
};
edgesByPair[key] = pe;
}
pe.SupportingCalls.Add((fromFn.Id, toFn.Id));
}
}
var adj = new Dictionary<Purl, HashSet<Purl>>();
foreach (var kv in edgesByPair)
{
var (from, to) = kv.Key;
if (!adj.TryGetValue(from, out var list))
{
list = new HashSet<Purl>();
adj[from] = list;
}
list.Add(to);
}
return new PurlGraphView
{
Adjacent = adj,
Edges = edgesByPair.Values.ToList()
};
}
```
This gives you:
* A coarse view of runtime dependencies between purls (“Purl A calls into Purl B”).
* Enough context to emit purl-level VEX or to reason about trust at package granularity.
---
## 7. JSON output and SBOM integration
### 7.1 JSON shape (high level)
You can emit a composite document:
```json
{
"image": "registry.example.com/app@sha256:...",
"modules": [
{
"moduleId": { "path": "/usr/lib/libssl.so.1.1", "format": "Elf" },
"purl": "pkg:deb/ubuntu/openssl@1.1.1w-0ubuntu1",
"arch": "x86_64"
}
],
"functions": [
{
"id": 42,
"name": "SSL_do_handshake",
"demangledName": null,
"module": { "path": "/usr/lib/libssl.so.1.1", "format": "Elf" },
"purl": "pkg:deb/ubuntu/openssl@1.1.1w-0ubuntu1",
"address": "0x401020",
"exported": true
}
],
"edges": [
{
"from": 10,
"to": 42,
"kind": "ImportCall",
"evidence": "ELF.R_X86_64_JUMP_SLOT"
}
],
"reachability": {
"roots": [1],
"reachableFunctions": [1,10,42]
},
"purlGraph": {
"edges": [
{
"from": "pkg:generic/myapp@1.0.0",
"to": "pkg:deb/ubuntu/openssl@1.1.1w-0ubuntu1",
"supportingCalls": [[10,42]]
}
]
},
"vulnerabilities": [
{
"id": "CVE-2024-XXXX",
"purl": "pkg:deb/ubuntu/openssl@1.1.1w-0ubuntu1",
"sinkFunctions": [42],
"reachable": true,
"paths": [
[1, 10, 42]
]
}
]
}
```
### 7.2 Purl resolution
Implement an `IPurlResolver` interface:
```csharp
public interface IPurlResolver
{
Purl ResolveForModule(string filePath, byte[] contentHash);
}
```
Possible implementations:
* `SbomPurlResolver` – given a CycloneDX/SPDX SBOM for the image, match by path or checksum.
* `LinuxPackagePurlResolver` – read `/var/lib/dpkg/status` / rpm DB in the filesystem.
* `GenericPurlResolver` – fallback: `pkg:generic/<hash>`.
You call the resolver in your loaders so that **every `BinaryModule` has a purl** and thus every `FunctionNode` has a purl.
---
## 8. Concrete implementation tasks for your team
1. **Data model & interfaces**
* Implement `ModuleId`, `FunctionNode`, `CallEdge`, `CallGraph`.
* Define `RawCallSite`, `BinaryModule`, and `IPurlResolver`.
2. **Loaders**
* `ElfLoader`: fill symbols, dynamic relocations (PLT), DT_NEEDED, etc.
* `PeLoader`: import descriptors, IAT, delay-load.
* `MachOLoader`: load commands, stubs, la_symbol_ptr, indirect symbols / chained fixups.
3. **Disassembly**
* `X86Disassembler` (iced) and `Arm64Disassembler` (Disarm or port).
* Function detection and `RawCallSite` extraction.
4. **CallGraphBuilder**
* Build intra-module edges from direct calls.
* Build inter-module edges using the format-specific rules above.
* Construct final `CallGraph` with adjacency maps and purl mappings.
5. **Reachability**
* Implement BFS/DFS from root functions.
* Projection to modules + purls.
* Vulnerability sink resolution & path reconstruction.
6. **Export**
* JSON serializer for the schema above.
* Optional: purl-level summary / VEX generator.
---
If you want, next step I can do a **more concrete design for `CallGraphBuilder`** (including per-format helper classes with method signatures) or a **C# skeleton** for the `ElfImportResolver`, `PeImportResolver`, and `MachOStubResolver` that plug directly into this plan.

Here’s a crisp idea that could give Stella Ops a real moat: **binary‑level reachability**—linking CVEs directly to the exact functions and offsets inside compiled artifacts (ELF/PE/Mach‑O), not just to packages.
---
### Why this matters (quick background)
* **Package‑level flags are noisy.** Most scanners say “vuln in `libX v1.2`,” but that library might be present and never executed.
* **Language‑level call graphs help** (when you have source or rich metadata), but containers often ship only **stripped binaries**.
* **Binary reachability** answers: *Is the vulnerable function actually in this image? Is its code path reachable from the entrypoints we observed or can construct?*
---
### The missing layer: Symbolization
Build a **symbolization layer** that normalizes debug and symbol info across platforms:
* **Inputs**: DWARF (ELF/Mach‑O), PDB (PE/Windows), symtabs, exported symbols, `.eh_frame`, and (when stripped) heuristic signatures (e.g., function byte‑hashes, CFG fingerprints).
* **Outputs**: a source‑agnostic map: `{binary → sections → functions → (addresses, ranges, hashes, demangled names, inlined frames)}`.
* **Normalization**: Put everything into a common schema (e.g., `Stella.Symbolix.v1`) so higher layers don’t care if it came from DWARF or PDB.
---
### End‑to‑end reachability (binary‑first, source‑agnostic)
1. **Acquire & parse**
* Detect format (ELF/PE/Mach‑O), parse headers, sections, symbol tables.
* If debug info present: parse DWARF/PDB; else fall back to disassembly + function boundary recovery.
2. **Function catalog**
* Assign stable IDs per function: `(imageHash, textSectionHash, startVA, size, fnHashXX)`.
* Record x‑refs (calls/jumps), imports/exports, PLT/IAT edges.
3. **Entrypoint discovery**
* Docker entry, process launch args, service scripts; infer likely mains (Go `main.main`, .NET hostfxr path, JVM launcher, etc.).
4. **Call‑graph build (binary CFG)**
* Build inter/intra‑procedural graph (direct + resolved indirect via IAT/PLT). Keep “unknown‑target” edges for conservative safety.
5. **CVE→function linking**
* Maintain a **signature bank** per CVE advisory: vulnerable function names, file paths, and—crucially—**byte‑sequence or basic‑block fingerprints** for patched vs vulnerable versions (works even when stripped).
6. **Reachability analysis**
* Is the vulnerable function present? Is there a path from any entrypoint to it (under conservative assumptions)? Tag as `Present+Reachable`, `Present+Uncertain`, or `Absent`.
7. **Runtime confirmation (optional, when users allow)**
* Lightweight probes (eBPF on Linux, ETW on Windows, perf/JFR/EventPipe) capture function hits; cross‑check with the static result to upgrade confidence.
---
### Minimal component plan (drop into Stella Ops)
* **Scanner.Symbolizer**
Parsers: ELF/DWARF (libdw or pure‑managed reader), PE/PDB (Dia/LLVM PDB), Mach‑O/DSYM.
Output: `Symbolix.v1` blobs stored in OCI layer cache.
* **Scanner.CFG**
Lifts functions to a normalized IR (capstone/iced‑x86 for decode) → builds CFG & call graph.
* **Advisory.FingerprintBank**
Ingests CSAF/OpenVEX plus curated fingerprints (fn names, block hashes, patch diff markers). Versioned, signed, air‑gap‑syncable.
* **Reachability.Engine**
Joins (`Symbolix` + `CFG` + `FingerprintBank`) → emits `ReachabilityEvidence` with lattice states for VEX.
* **VEXer.Adapter**
Emits **OpenVEX** statements with `status: affected/not_affected` and `justification: function_not_present | function_not_reachable | mitigated_at_runtime`, attaching Evidence URIs.
* **Console UX**
“Why not affected?” panel showing entrypoint→…→function path (or absence), with byte‑hash proof.
---
### Data model sketch (concise)
* `ImageFunction { id, name?, startVA, size, fnHash, sectionHash, demangled?, provenance:{DWARF|PDB|Heuristic} }`
* `Edge { srcFnId, dstFnId, kind:{direct|plt|iat|indirect?} }`
* `CveSignature { cveId, fnName?, libHints[], blockFingerprints[], versionRanges }`
* `Evidence { cveId, imageId, functionMatches[], reachable: bool?, confidence:[low|med|high], method:[static|runtime|hybrid] }`
---
### Practical phases (8–10 weeks of focused work)
1. **P0**: ELF/DWARF symbolizer + basic function catalog; link a handful of CVEs via name‑only; emit OpenVEX `function_not_present`.
2. **P1**: CFG builder (direct calls) + PLT/IAT resolution; simple reachability; first fingerprints for top 50 CVEs in glibc, openssl, curl, zlib.
3. **P2**: Stripped‑binary heuristics (block hashing) + Go/Rust name demangling; Windows PDB ingestion for PE.
4. **P3**: Runtime probes (opt‑in) + confidence upgrade logic; Console path explorer; evidence signing (DSSE).
---
### KPIs to prove the moat
* **Noise cut**: % reduction in “affected” flags after reachability (target 40–70% on typical containers).
* **Precision**: Ground‑truth validation vs PoC images (TP/FP/FN on presence & reachability).
* **Coverage**: % images where we can make a determination without source (goal: >80%).
* **Latency**: Added scan time per image (<15s typical with caches).
---
### Risks & how to handle them
* **Stripped binaries** → mitigate with block‑hash fingerprints & library‑version heuristics.
* **Obfuscated/packed code** → mark `Uncertain`; allow user‑supplied hints; prefer runtime confirmation.
* **Advisory inconsistency** → keep our own curated CVE→function fingerprint bank; sign & version it.
* **Platform spread** → start Linux/ELF, then Windows/PDB, then Mach‑O.
---
### Why competitors struggle
Most tools stop at packages because binary CFG + fingerprint curation is hard and expensive. Shipping a **source‑agnostic reachability engine** tied to signed evidence in VEX would set Stella Ops apart—especially in offline/air‑gapped and sovereign contexts you already target.
If you want, I can draft:
* the `Symbolix.v1` protobuf,
* a tiny PoC (ELF→functions→match CVE with a block fingerprint),
* and the OpenVEX emission snippet your VEXer can produce.
Below is a detailed architecture plan for implementing reachability and call-graph analysis in Stella Ops, covering JavaScript, Python, PHP, and binaries, and integrating with your existing Scanner / Concelier / VEXer stack.
I will assume:
* .NET 10 for core services.
* Scanner is the place where all “trust algebra / lattice” runs (per your standing rule).
* Concelier and VEXer remain “preserve/prune” layers and do not run lattice logic.
* Output must be JSON-centric with PURLs and OpenVEX.
---
## 1. Scope & Objectives
### 1.1 Primary goals
1. From an OCI image, build:
* A **library-level usage graph** (which libraries are used by which entrypoints).
* A **function-level call graph** for JS / Python / PHP / binaries.
2. Map CVEs (from Concelier) to:
* Concrete **components** (PURLs) in the SBOM.
* Concrete **functions / entrypoints / code regions** inside those components.
3. Perform **reachability analysis** to classify each vulnerability as:
* `present + reachable`
* `present + not_reachable`
* `function_not_present` (no vulnerable symbol)
* `uncertain` (dynamic features, unresolved calls)
4. Emit:
* **Structured JSON** with PURLs and call-graph nodes/edges (“reachability evidence”).
* **OpenVEX** documents with appropriate `status`/`justification`.
### 1.2 Non-goals (for now)
* Full dynamic analysis of the running container (eBPF, ptrace, etc.) – leave as Phase 3+ optional add-on.
* Perfect call graph precision for dynamic languages (aim for safe, conservative approximations).
* Automatic “fix recommendations” (handled by other Stella Ops agents later).
---
## 2. High-Level Architecture

## 3. Data Model & JSON Contracts
### 3.1 Core IR types (Scanner.Reachability)
Define in a central assembly, e.g. `StellaOps.Scanner.Reachability`:
```csharp
public record ComponentRef(
string Purl,
string? BomRef,
string? Name,
string? Version);
public enum SymbolKind { Function, Method, Constructor, Lambda, Import, Export }
public record SymbolId(
string Language, // "js", "python", "php", "binary"
string ComponentPurl, // SBOM component PURL or "" for app code
string LogicalName, // e.g., "server.js:handleLogin"
string? FilePath,
int? Line);
public record CallGraphNode(
string Id, // stable id, e.g., hash(SymbolId)
SymbolId Symbol,
SymbolKind Kind,
bool IsEntrypoint);
public enum CallEdgeKind { Direct, Indirect, Dynamic, External, Ffi }
public record CallGraphEdge(
string FromNodeId,
string ToNodeId,
CallEdgeKind Kind);
public record CallGraph(
string GraphId,
IReadOnlyList<CallGraphNode> Nodes,
IReadOnlyList<CallGraphEdge> Edges);
```
### 3.2 Vulnerability mapping
```csharp
public record VulnerabilitySignature(
string Source, // "csaf", "nvd", "vendor"
string Id, // "CVE-2023-12345"
IReadOnlyList<string> Purls,
IReadOnlyList<string> TargetSymbolPatterns, // glob-like or regex
IReadOnlyList<string>? FilePathPatterns,
IReadOnlyList<string>? BlockFingerprints // for binaries, optional
);
```
### 3.3 Reachability evidence
```csharp
public enum ReachabilityStatus
{
PresentReachable,
PresentNotReachable,
FunctionNotPresent,
Unknown
}
public record ReachabilityEvidence
(
string ImageRef,
string VulnId, // CVE or advisory id
ComponentRef Component,
ReachabilityStatus Status,
double Confidence, // 0..1
string Method, // "static-callgraph", "binary-fingerprint", etc.
IReadOnlyList<string> EntrypointNodeIds,
IReadOnlyList<IReadOnlyList<string>>? ExamplePaths // optional list of node-paths
);
```
### 3.4 JSON structure (external)
Minimal external JSON (what you store / expose):
```json
{
"image": "registry.example.com/app:1.2.3",
"components": [
{
"purl": "pkg:npm/express@4.18.0",
"bomRef": "component-1"
}
],
"callGraphs": [
{
"graphId": "js-main",
"language": "js",
"nodes": [ /* CallGraphNode */ ],
"edges": [ /* CallGraphEdge */ ]
}
],
"reachability": [
{
"vulnId": "CVE-2023-12345",
"componentPurl": "pkg:npm/express@4.18.0",
"status": "PresentReachable",
"confidence": 0.92,
"entrypoints": [ "node:..." ],
"paths": [
["node:entry", "node:routeHandler", "node:vulnFn"]
]
}
]
}
```
---
## 4. Scanner-Side Architecture
### 4.1 Project layout (suggested)
```text
src/
Scanner/
StellaOps.Scanner.WebService/
StellaOps.Scanner.Worker/
StellaOps.Scanner.Core/ # shared scan domain
StellaOps.Scanner.Reachability/
StellaOps.Scanner.Symbolization/
StellaOps.Scanner.Cfg/
StellaOps.Scanner.Analyzers.JavaScript/
StellaOps.Scanner.Analyzers.Python/
StellaOps.Scanner.Analyzers.Php/
StellaOps.Scanner.Analyzers.Binary/
```
### 4.2 API surface (Scanner.WebService)
* `POST /api/scan/image`
* Request: `{ "imageRef": "...", "profile": { "reachability": true, ... } }`
* Returns: scan id.
* `GET /api/scan/{id}/reachability`
* Returns: `ReachabilityEvidence[]`, plus call graph summary (optional).
* `GET /api/scan/{id}/vex`
* Returns: OpenVEX with statuses based on reachability lattice.
### 4.3 Worker orchestration
`StellaOps.Scanner.Worker`:
1. Receives scan job with `imageRef`.
2. Extracts filesystem (layered rootfs) under `/mnt/scans/{scanId}/rootfs`.
3. Invokes SBOM generator (CycloneDX/SPDX).
4. Invokes Concelier via offline feeds to get:
* Component vulnerabilities (CVE list per PURL).
* Vulnerability signatures (fingerprints).
5. Builds a `ReachabilityPlan`:
```csharp
public record ReachabilityPlan(
IReadOnlyList<ComponentRef> Components,
IReadOnlyList<VulnerabilitySignature> Vulns,
IReadOnlyList<AnalyzerTarget> AnalyzerTargets // files/dirs grouped by language
);
```
6. For each language target, dispatch analyzer:
* JavaScript: `IReachabilityAnalyzer` implementation for JS.
* Python: likewise.
* PHP: likewise.
* Binary: symbolizer + CFG.
7. Collects call graphs from each analyzer and merges them into a single IR (or separate per-language graphs with shared IDs).
8. Sends merged graphs + vuln list to **Reachability Engine** (Scanner.Reachability).
---
## 5. Language Analyzers (JS / Python / PHP)
All analyzers implement a common interface:
```csharp
public interface IReachabilityAnalyzer
{
string Language { get; } // "js", "python", "php"
Task<CallGraph> AnalyzeAsync(AnalyzerContext context, CancellationToken ct);
}
public record AnalyzerContext(
string RootFsPath,
IReadOnlyList<ComponentRef> Components,
IReadOnlyList<VulnerabilitySignature> Vulnerabilities,
IReadOnlyDictionary<string, string> Env, // container env, entrypoint, etc.
string? EntrypointCommand // container CMD/ENTRYPOINT
);
```
### 5.1 JavaScript (Node.js focus)
**Inputs:**
* `/app` tree inside container (or discovered via SBOM).
* `package.json` files.
* Container entrypoint (e.g., `["node", "server.js"]`).
**Core steps:**
1. Identify **app root**:
* Heuristics: directory containing `package.json` that owns the entry script.
2. Parse:
* All `.js`, `.mjs`, `.cjs` in app and `node_modules` for vulnerable PURLs.
* Use a parsing frontend (e.g., Tree-sitter via .NET binding, or Node+AST-as-JSON).
3. Build module graph:
* `require`, `import`, `export`.
4. Function-level graph:
* For each function/method, create `CallGraphNode`.
* For each `callExpression`, create `CallGraphEdge` (try to resolve callee).
5. Entrypoints:
* Main script in CMD/ENTRYPOINT.
* HTTP route handlers (for express/koa) detected by patterns (e.g., `app.get("/...")`).
6. Map vulnerable symbols:
* From `VulnerabilitySignature.TargetSymbolPatterns` (e.g., `express/lib/router/layer.js:handle_request`).
* Identify nodes whose `SymbolId` matches patterns.
**Output:**
* `CallGraph` for JS with:
* `IsEntrypoint = true` for main and detected handlers.
* Node attributes include file path, line, component PURL.
### 5.2 Python
**Inputs:**
* Site-packages paths from SBOM.
* Entrypoint script (CMD/ENTRYPOINT).
* Framework heuristics (Django, Flask) from environment variables or common entrypoints.
**Core steps:**
1. Discover Python interpreter chain: not needed for pure static, but useful for heuristics.
2. Parse `.py` files of:
* App code.
* Vulnerable packages (per PURL).
3. Build module import graph (`import`, `from x import y`).
4. Function-level graph:
* Nodes for functions, methods, class constructors.
* Edges for call expressions; conservative for dynamic calls.
5. Entrypoints:
* Main script.
* WSGI callable (e.g., `application` in `wsgi.py`).
* Django URLconf -> view functions.
6. Map vulnerable symbols using `TargetSymbolPatterns` like `django.middleware.security.SecurityMiddleware.__call__`.
### 5.3 PHP
**Inputs:**
* Web root (from container image or conventional paths `/var/www/html`, `/app/public`, etc.).
* Composer metadata (`composer.json`, `vendor/`).
* Web server config if present (optional).
**Core steps:**
1. Discover front controllers (e.g., `index.php`, `public/index.php`).
2. Parse PHP files (again, via Tree-sitter or any suitable parser).
3. Resolve include/require chains to build file-level inclusion graph.
4. Build function/method graph:
* Functions, methods, class constructors.
* Calls with best-effort resolution for namespaced functions.
5. Entrypoints:
* Front controllers and router entrypoints (e.g., Symfony, Laravel detection).
6. Map vulnerable symbols (e.g., functions in certain vendor packages, particular methods).
---
## 6. Binary Analyzer & Symbolizer
Project: `StellaOps.Scanner.Analyzers.Binary` + `Symbolization` + `Cfg`.
### 6.1 Inputs
* All binaries and shared libraries in:
* `/usr/lib`, `/lib`, `/app/bin`, etc.
* SBOM link: each binary mapped to its component PURL when possible.
* Vulnerability signatures for native libs: function names, symbol names, fingerprints.
### 6.2 Symbolization
Module: `StellaOps.Scanner.Symbolization`
* Detect format: ELF, PE, Mach-O.
* For ELF/Mach-O:
* Parse symbol tables (`.symtab`, `.dynsym`).
* Parse DWARF (if present) to map functions to source files/lines.
* For PE:
* Parse PDB (if present) or export table.
* For stripped binaries:
* Run function boundary recovery (linear sweep + heuristic).
* Compute block/fn-level hashes for fingerprinting.
Output:
```csharp
public record ImageFunction(
string ImageId, // e.g., SHA256 of file
ulong StartVa,
uint Size,
string? SymbolName, // demangled if possible
string FnHash, // stable hash of bytes / CFG
string? SourceFile,
int? SourceLine);
```
### 6.3 CFG + Call graph
Module: `StellaOps.Scanner.Cfg`
* Disassemble `.text` using Capstone/Iced.x86.
* Build basic blocks and CFG.
* Identify:
* Direct calls (resolved).
* PLT/IAT indirections to shared libraries.
* Build `CallGraph` for binary functions:
* Entrypoints: `main`, exported functions, Go `main.main`, etc.
* Map application functions to library functions via PLT/IAT edges.
### 6.4 Linking vulnerabilities
* For each vulnerability affecting a native library (e.g., OpenSSL):
* Map to candidate binaries via SBOM + PURL.
* Within library image, find `ImageFunction`s matching:
* `SymbolName` patterns.
* `FnHash` / `BlockFingerprints` (for precise detection).
* Determine reachability:
* Starting from application entrypoints, traverse call graph to see if calls to vulnerable library function occur.
---
## 7. Reachability Engine & Lattice (Scanner.WebService)
Project: `StellaOps.Scanner.Reachability`
### 7.1 Inputs to engine
* Combined `CallGraph[]` (per language + binary).
* Vulnerability list (CVE, GHSA, etc.) with affected PURLs.
* Vulnerability signatures.
* Entrypoint hints:
* Container CMD/ENTRYPOINT.
* Detected HTTP handlers, WSGI/PSGI entrypoints, etc.
### 7.2 Algorithm steps
1. **Entrypoint expansion**
* Identify all `CallGraphNode` with `IsEntrypoint=true`.
* Add language-specific “framework entrypoints” (e.g., Express route dispatch, Django URL dispatch) when detected.
2. **Graph traversal**
* For each entrypoint node:
* BFS/DFS through edges.
* Maintain `reachable` bit on each node.
* For dynamic edges:
* Conservative: if target cannot be resolved, mark affected path as partially unknown and downgrade confidence.
3. **Vuln symbol resolution**
* For each vulnerability:
* For each vulnerable component PURL found in SBOM:
* Find candidate nodes whose `SymbolId` matches `TargetSymbolPatterns` / binary fingerprints.
* If none found:
* `FunctionNotPresent` (if component version range indicates vulnerable but we cannot find symbol – low confidence).
* If found:
* Check `reachable` bit:
* If reachable by at least one entrypoint, `PresentReachable`.
* Else, `PresentNotReachable`.
4. **Confidence computation**
* Start from:
* `1.0` for direct match with explicit function name & static call.
* Lower for:
* Heuristic framework entrypoints.
* Dynamic calls.
* Fingerprint-only matches on stripped binaries.
* Example rule-of-thumb:
* direct static path only: 0.95–1.0.
* dynamic edges but symbol found: 0.7–0.9.
* symbol not found but version says vulnerable: 0.4–0.6.
5. **Lattice merge**
* Represent each CVE+component pair as a lattice element with states: `{affected, not_affected, unknown}`.
* Reachability engine produces a **local state**:
* `PresentReachable` → candidate `affected`.
* `PresentNotReachable` or `FunctionNotPresent` → candidate `not_affected`.
* `Unknown` → `unknown`.
* Merge with:
* Upstream vendor VEX (from Concelier).
* Policy overrides (e.g., “treat certain CVEs as affected unless vendor says otherwise”).
* Final state computed here (Scanner.WebService), not in Concelier or VEXer.
6. **Evidence output**
* For each vulnerability:
* Emit `ReachabilityEvidence` with:
* Status.
* Confidence.
* Method.
* Example entrypoint paths (for UX and audit).
* Persist this evidence alongside regular scan results.
---
## 8. Integration with SBOM & VEX
### 8.1 SBOM annotation
* Extend SBOM documents (CycloneDX / SPDX) with extra properties:
* CycloneDX:
* `component.properties`:
* `stellaops:reachability:status` = `present_reachable|present_not_reachable|function_not_present|unknown`
* `stellaops:reachability:confidence` = `0.0-1.0`
* SPDX:
* `Annotation` or `ExternalRef` with similar metadata.
### 8.2 OpenVEX generation
Module: `StellaOps.Vexer.Adapter.Reachability`
* For each `(vuln, component)` pair:
* Map to VEX statement:
* If `PresentReachable`:
* `status: affected`
* `justification: component_not_fixed` or similar.
* If `PresentNotReachable`:
* `status: not_affected`
* `justification: function_not_reachable`
* If `FunctionNotPresent`:
* `status: not_affected`
* `justification: component_not_present` or `function_not_present`
* If `Unknown`:
* `status: under_investigation` (configurable).
* Attach evidence via:
* `analysis` / `details` fields (link to internal evidence JSON or audit link).
* VEXer does not recalculate reachability; it uses the already computed decision + evidence.
---
## 9. Executable Containers & Offline Operation
### 9.1 Executable containers
* Analyzers run inside a dedicated Scanner worker container that has:
* .NET 10 runtime.
* Language runtimes if needed for parsing (Node, Python, PHP), or Tree-sitter-based parsing.
* Target image filesystem is mounted read-only under `/mnt/rootfs`.
* No network access (offline/air-gap).
* This satisfies “we will use executable containers” while keeping separation between:
* Target image (mount only).
* Analyzer container (StellaOps code).
### 9.2 Offline signature bundles
* Concelier periodically exports:
* Vulnerability database (CSAF/NVD).
* Vulnerability Signature Bank.
* Bundles are:
* DSSE-signed.
* Versioned (e.g., `signatures-2025-11-01.tar.zst`).
* Scanner uses:
* The bundle digest as part of the **Scan Manifest** for deterministic replay.
---
## 10. Determinism & Caching
### 10.1 Layer-level caching
* Key: `layerDigest + analyzerVersion + signatureBundleVersion`.
* Cache artifacts:
* CallGraph(s) per layer (for JS/Python/PHP code present in that layer).
* Symbolization results per binary file hash.
* For images sharing layers:
* Merge cached graphs instead of re-analyzing.
### 10.2 Deterministic scan manifest
For each scan, produce:
```json
{
"imageRef": "registry/app:1.2.3",
"imageDigest": "sha256:...",
"scannerVersion": "1.4.0",
"analyzerVersions": {
"js": "1.0.0",
"python": "1.0.0",
"php": "1.0.0",
"binary": "1.0.0"
},
"signatureBundleDigest": "sha256:...",
"callGraphDigest": "sha256:...", // canonical JSON hash
"reachabilityEvidenceDigest": "sha256:..."
}
```
This manifest can be signed (Authority module) and used for audits and replay.
---
## 11. Implementation Roadmap (Phased)
### Phase 0 – Infrastructure & Binary presence
**Duration:** 1 sprint
* Set up `Scanner.Reachability` core types and interfaces.
* Implement:
* Basic Symbolizer for ELF + DWARF.
* Binary function catalog without CFG.
* Link a small set of CVEs to binary function presence via `SymbolName`.
* Expose minimal evidence:
* `PresentReachable`/`FunctionNotPresent` based only on presence (no call graph).
* Integrate with VEXer to emit `function_not_present` justifications.
**Success criteria:**
* For selected demo images with known vulnerable/ patched OpenSSL, scanner can:
* Distinguish images where vulnerable function is present vs. absent.
* Emit OpenVEX with correct `not_affected` when patched.
---
### Phase 1 – JS/Python/PHP call graphs & basic reachability
**Duration:** 1–2 sprints
* Implement:
* `Scanner.Analyzers.JavaScript` with module + function call graph.
* `Scanner.Analyzers.Python` and `Scanner.Analyzers.Php` with basic graphs.
* Entrypoint detection:
* JS: main script from CMD, basic HTTP handlers.
* Python: main script + Django/Flask heuristics.
* PHP: front controllers.
* Implement core reachability algorithm (BFS/DFS).
* Implement simple `VulnerabilitySignature` that uses function names and file paths.
* Hook lattice engine in Scanner.WebService and integrate with:
* Concelier vulnerability feeds.
* VEXer.
**Success criteria:**
* For demo apps (Node, Django, Laravel):
* Identify vulnerable functions and mark them reachable/unreachable.
* Demonstrate noise reduction (some CVEs flagged as `not_affected`).
---
### Phase 2 – Binary CFG & Fingerprinting, Improved Confidence
**Duration:** 1–2 sprints
* Extend Symbolizer & CFG for:
* Stripped binaries (function hashing).
* Shared libraries (PLT/IAT resolution).
* Implement `VulnerabilitySignature.BlockFingerprints` to distinguish patched vs vulnerable binary functions.
* Refine confidence scoring:
* Use fingerprint match quality.
* Consider presence/absence of debug info.
* Expand coverage:
* glibc, curl, zlib, OpenSSL, libxml2, etc.
**Success criteria:**
* For curated images:
* Confirm ability to differentiate patched vs vulnerable versions even when binaries are stripped.
* Reachability reflects true call paths across app→lib boundaries.
---
### Phase 3 – Runtime hooks (optional), UX, and Hardening
**Duration:** 2+ sprints
* Add opt-in runtime confirmation:
* eBPF probes for function hits (Linux).
* Map runtime addresses back to `ImageFunction` via symbolization.
* Enhance console UX:
* Path explorer UI: show entrypoint → … → vulnerable function path.
* Evidence view with hash-based proofs.
* Hardening:
* Performance optimization for large images (parallel analysis, caching).
* Conservative fallbacks for dynamic language features.
**Success criteria:**
* For selected environments where runtime is allowed:
* Static reachability is confirmed by runtime traces in majority of cases.
* No significant performance regression on typical images.
---
## 12. How this satisfies your initial bullets
From your initial requirements:
1. **JavaScript, Python, PHP, binary**
→ Dedicated analyzers per language + binary symbolization/CFG, unified in `Scanner.Reachability`.
2. **Executable containers**
→ Analyzers run inside Scanner’s worker container, mounting the target image rootfs; no network access.
3. **Libraries usage call graph**
→ Call graphs map from entrypoints → app code → library functions; SBOM + PURLs tie functions to libraries.
4. **Reachability analysis**
→ BFS/DFS from entrypoints over per-language and binary graphs, with lattice-based merging in `Scanner.WebService`.
5. **JSON + PURLs**
→ All evidence is JSON with PURL-tagged components; SBOM is annotated, and VEX statements reference those PURLs.
---
If you like, next step can be: I draft concrete C# interface definitions (including some initial Tree-sitter integration stubs for JS/Python/PHP) and a skeleton of the `ReachabilityPlan` and `ReachabilityEngine` classes that you can drop into the monorepo.

Here’s a crisp idea you can drop straight into Stella Ops: treat “unknowns” as first‑class data, not noise.
---
# Unknowns Registry — turning uncertainty into signals
**Why:** Scanners and VEX feeds miss things (ambiguous package IDs, unverifiable hashes, orphaned layers, missing SBOM edges, runtime-only artifacts). Today these get logged and forgotten. If we **structure** them, downstream agents can reason about risk and shrink blast radius proactively.
**What it is:** A small service + schema that records every uncertainty with enough context for later inference.
## Core model (v0)
```json
{
"unknown_id": "unk:sha256:…",
"observed_at": "2025-11-18T12:00:00Z",
"provenance": {
"source": "Scanner.Analyzer.DotNet|Sbomer|Signals|Vexer",
"host": "runner-42",
"scan_id": "scan:…"
},
"scope": {
"artifact": { "type": "oci.image", "ref": "registry/app@sha256:…" },
"subpath": "/app/bin/Contoso.dll",
"phase": "build|scan|runtime"
},
"unknown_type": "identity_gap|version_conflict|hash_mismatch|missing_edge|runtime_shadow|policy_undecidable",
"evidence": {
"raw": "nuget id 'Serilog' but assembly name 'Serilog.Core'",
"signals": ["sym:Serilog.Core.Logger", "procopen:/app/agent"]
},
"transitive": {
"depth": 2,
"parents": ["pkg:nuget/Serilog@?"],
"children": []
},
"confidence": { "p": 0.42, "method": "bayes-merge|rule" },
"exposure_hints": {
"surface": ["logging pipeline", "startup path"],
"runtime_hits": 3
},
"status": "open|triaged|suppressed|resolved",
"labels": ["reachability:possible", "sbom:incomplete"]
}
```
## Categorize by three axes
* **Provenance** (where it came from): Scanner vs Sbomer vs Vexer vs Signals.
* **Scope** (what it touches): image/layer/file/symbol/runtime‑proc/policy.
* **Transitive depth** (how far from an entry point): 0 = direct, 1..N via deps.
## How agents use it
* **Cartographer**: includes unknown edges in the graph with special weight; lets Policy/Lattice down‑rank vulnerable nodes near high‑impact unknowns.
* **Remedy Assistant (Zastava)**: proposes micro‑probes (“add EventPipe/JFR tap for X symbol”) or build‑time assertions (“pin Serilog>=3.1, regenerate SBOM”).
* **Scheduler**: prioritizes scans where unknown density × asset criticality is highest.
## Minimal API (idempotent, additive)
* `POST /unknowns/ingest` — upsert by `unknown_id` (hash of type+scope+evidence).
* `GET /unknowns?artifact=…&status=open` — list for a target.
* `POST /unknowns/:id/triage` — set status/labels, attach rationale.
* `GET /metrics` — density by artifact/namespace/unknown_type.
*All additive; no versioning required. Repeat calls with the same payload are no‑ops.*
## Scoring hook (into your lattice)
* Add a **“Unknowns Pressure”** term:
`risk = base ⊕ (α * density_depth≤1) ⊕ (β * runtime_shadow) ⊕ (γ * policy_undecidable)`
* Gate “green” only if `density_depth≤1 == 0` **or** compensating controls active.
## Storage & plumbing
* **Store:** append‑only KV (Badger/Rocks) + Graph overlay (SQLite/Neo4j—your call).
* **Emit:** DSSE‑signed “Unknowns Attestation” per scan for replayable audits.
* **UI:** heatmap per artifact (unknowns by type × depth), drill‑down to evidence.
## First 2‑day slice
1. Define `unknown_type` enum + hashable `unknown_id`.
2. Wire Scanner/Sbomer/Vexer to emit unknowns (start with: identity_gap, missing_edge).
3. Persist + expose `/metrics` (density, by depth and type).
4. In Policy Studio, add the Unknowns Pressure term with default α/β/γ.
If you want, I’ll draft the exact protobuf/JSON schema and drop a .NET 10 record types + EF model, plus a tiny CLI to query and a Grafana panel JSON.
I will treat “it” as the whole vision behind **Pushing Binary Reachability Toward True Determinism** inside Stella Ops: function-/symbol-level reachability for binaries and higher-level languages, wired into Scanner, Cartographer, Signals, and VEX.
Below is an implementation-oriented architecture plan you can hand directly to agents.
---
## 1. Scope, goals, and non-negotiable invariants
### 1.1. Scope
Deliver a deterministic reachability pipeline for containers that:
1. Builds **call graphs** and **symbol usage maps** for:
* Native binaries (ELF, PE, Mach-O) — primary for this branch.
* Scripted/VM languages later: JS, Python, PHP (as part of the same architecture).
2. Maps symbols and functions to:
* Packages (purls).
* Vulnerabilities (CVE → symbol/function list via Concelier/VEX data).
3. Computes **deterministic reachability states** for each `(vulnerability, artifact)` pair.
4. Emits:
* Machine-readable JSON (with `purl`s).
* Graph overlays for Cartographer.
* Inputs for the lattice/trust engine and VEXer/Excitor.
### 1.2. Invariants
* **Deterministic replay**: Given the same:
* Image digest(s),
* Analyzer versions,
* Config + policy,
* Runtime trace inputs (if any),
the same reachability outputs must be produced, bit-for-bit.
* **Idempotent, additive APIs**:
* No versioning of endpoints, only additive/optional fields.
* Same request = same response, no side effects besides storing/caching.
* **Lattice logic runs in `Scanner.WebService`**:
* All “reachable/unreachable/unknown” and confidence merging lives in Scanner, not Concelier/Excitors.
* **Preserve prune source**:
* Concelier and Excitors preserve provenance and do not “massage” reachability; they only consume it.
* **Offline, air-gap friendly**:
* No mandatory external calls; dependency on local analyzers and local advisory/VEX cache.
---
## 2. High-level pipeline
From container image to reachability output:
1. **Image enumeration**
`Scanner.WebService` receives an image ref or tarball and spawns an analysis run.
2. **Binary discovery & classification**
Binary analyzers detect ELF/PE/Mach-O + main interpreters (python, node, php) and scripts.
3. **Symbolization & call graph building**
* For each binary/module, we produce:
* Symbol table (exported + imported).
* Call graph edges (function-level where possible).
* For dynamic languages, we later plug in appropriate analyzers.
4. **Symbol→package mapping**
* Match symbols to packages and `purl`s using:
* Known vendor symbol maps (from Concelier / Feedser).
* Heuristics, path patterns, build IDs.
5. **Vulnerability→symbol mapping**
* From Concelier/VEX/CSAF: map each CVE to the set of symbols/functions it affects.
6. **Reachability solving**
* For each `(CVE, artifact)`:
* Determine presence and reachability of affected symbols from known entrypoints.
* Merge static call graph and runtime signals (if available) via deterministic lattice.
7. **Output & storage**
* Reachability JSON with purls and confidence.
* Graph overlay into Cartographer.
* Signals/events for downstream scoring.
* DSSE-signed reachability attestation for replay/audit.
---
## 3. Component architecture
### 3.1. New and extended services
1. **`StellaOps.Scanner.WebService` (extended)**
* Orchestration of reachability analyses.
* Lattice/merging engine.
* Idempotent reachability APIs.
2. **`StellaOps.Scanner.Analyzers.Binary.*` (new)**
* `…Binary.Discovery`: file type detection, ELF/PE/Mach-O parsing.
* `…Binary.Symbolizer`: resolves symbols, imports/exports, relocations.
* `…Binary.CallGraph.Native`: builds call graphs where possible (via disassembly/CFG).
* `…Binary.CallGraph.DynamicStubs`: heuristics for indirect calls, PLT/GOT, vtables.
3. **`StellaOps.Scanner.Analyzers.Script.*` (future extension)**
* `…Lang.JavaScript.CallGraph`
* `…Lang.Python.CallGraph`
* `…Lang.Php.CallGraph`
* These emit the same generic call-graph IR.
4. **`StellaOps.Reachability.Engine` (within Scanner.WebService)**
* Normalizes all call graphs into a common IR.
* Merges static and dynamic evidence.
* Computes reachability states and scores.
5. **`StellaOps.Cartographer.ReachabilityOverlay` (new overlay module)**
* Stores per-artifact call graphs and reachability tags.
* Provides graph queries for UI and policy tools.
6. **`StellaOps.Signals` (extended)**
* Ingests runtime call traces (e.g., from EventPipe/JFR/ebpf in other branches).
* Feeds function-hit events into the Reachability Engine.
7. **Unknowns Registry integration (optional but recommended)**
* Stores unresolved symbol/package mappings and incomplete edges as `unknowns`.
* Used to adjust risk scores (“Unknowns Pressure”) when binary analysis is incomplete.
---
## 4. Detailed design by layer
### 4.1. Static analysis layer (binaries)
#### 4.1.1. Binary discovery
Module: `StellaOps.Scanner.Analyzers.Binary.Discovery`
* Inputs:
* Per-image file list (from existing Scanner).
* Byte slices of candidate binaries.
* Logic:
* Detect ELF/PE/Mach-O via magic bytes, not extensions.
* Classify as:
* Main executable
* Shared library
* Plugin/module
* Output:
* `binary_manifest.json` per image:
```json
{
"image_ref": "registry/app@sha256:…",
"binaries": [
{
"id": "bin:elf:/usr/local/bin/app",
"path": "/usr/local/bin/app",
"format": "elf",
"arch": "x86_64",
"role": "executable"
}
]
}
```
#### 4.1.2. Symbolization
Module: `StellaOps.Scanner.Analyzers.Binary.Symbolizer`
* Uses:
* ELF/PE/Mach-O parsers (internal or third-party), no external calls.
* Output per binary:
```json
{
"binary_id": "bin:elf:/usr/local/bin/app",
"build_id": "buildid:abcd…",
"exports": ["pkg1::ClassA::method1", "..."],
"imports": ["openssl::EVP_EncryptInit_ex", "..."],
"sections": { "text": { "va": "0x...", "size": 12345 } }
}
```
* Writes unresolved symbol sets to Unknowns Registry when:
* Imports cannot be tied to known packages or symbols.
#### 4.1.3. Call graph construction
Module: `StellaOps.Scanner.Analyzers.Binary.CallGraph.Native`
* Core tasks:
* Build control-flow graphs (CFG) for each function via:
* Disassembly.
* Basic block detection.
* Identify direct calls (`call func`) and indirect calls (function pointers, vtables).
* IR model:
```json
{
"binary_id": "bin:elf:/usr/local/bin/app",
"functions": [
{ "fid": "func:app::main", "va": "0x401000", "size": 128 },
{ "fid": "func:libssl::EVP_EncryptInit_ex", "external": true }
],
"edges": [
{ "caller": "func:app::main", "callee": "func:app::init_config", "type": "direct" },
{ "caller": "func:app::main", "callee": "func:libssl::EVP_EncryptInit_ex", "type": "import" }
]
}
```
* Edge confidence:
* `type: direct|import|indirect|heuristic`
* Used later by the lattice.
#### 4.1.4. Entry point inference
* Sources:
* ELF `PT_INTERP`, PE `AddressOfEntryPoint`.
* Application-level hints (known frameworks, service main methods).
* Container metadata (CMD, ENTRYPOINT).
* Output:
```json
{
"binary_id": "bin:elf:/usr/local/bin/app",
"entrypoints": ["func:app::main"]
}
```
> Note: For JS/Python/PHP, equivalent analyzers will later define module entrypoints (`index.js`, `wsgi_app`, `public/index.php`).
---
### 4.2. Symbol-to-package and CVE-to-symbol mapping
#### 4.2.1. Symbol→package mapping
Module: `StellaOps.Reachability.Mapping.SymbolToPurl`
* Inputs:
* Binary symbolization outputs.
* Local mapping DB in Concelier (vendor symbol maps, debug info, name patterns).
* File path + container context (`/usr/lib/...`, `/site-packages/...`).
* Output:
```json
{
"symbol": "libssl::EVP_EncryptInit_ex",
"purl": "pkg:apk/alpine/openssl@3.1.5-r2",
"confidence": 0.93,
"method": "vendor_map+path_heuristic"
}
```
* Unresolved / ambiguous symbols:
* Stored as `unknowns` of type `identity_gap`.
#### 4.2.2. CVE→symbol mapping
Responsibility: Concelier + its advisory ingestion.
* For each vulnerability:
```json
{
"cve_id": "CVE-2025-12345",
"purl": "pkg:apk/alpine/openssl@3.1.5-r2",
"affected_symbols": [
"libssl::EVP_EncryptInit_ex",
"libssl::EVP_EncryptUpdate"
],
"source": "vendor_vex",
"confidence": 1.0
}
```
* Reachability Engine consumes this mapping read-only.
---
### 4.3. Reachability Engine
Module: `StellaOps.Reachability.Engine` (in Scanner.WebService)
#### 4.3.1. Core data model
Per `(artifact, cve, purl)`:
```json
{
"artifact": { "type": "oci.image", "ref": "registry/app@sha256:…" },
"cve_id": "CVE-2025-12345",
"purl": "pkg:apk/alpine/openssl@3.1.5-r2",
"symbols": [
{
"symbol": "libssl::EVP_EncryptInit_ex",
"static_presence": "present|absent|unknown",
"static_reachability": "reachable|unreachable|unknown",
"runtime_hits": 3,
"runtime_reachability": "observed|not_observed|unknown"
}
],
"reachability_state": "confirmed_reachable|statically_reachable|present_not_reachable|not_present|unknown",
"confidence": {
"p": 0.87,
"evidence": ["static_callgraph", "runtime_trace", "symbol_map"],
"unknowns_pressure": 0.12
}
}
```
#### 4.3.2. Lattice / state machine
Define a deterministic lattice over states:
* `NOT_PRESENT`
* `PRESENT_NOT_REACHABLE`
* `STATICALLY_REACHABLE`
* `RUNTIME_OBSERVED`
And “unknown” flags overlayed when evidence is missing.
Merging rules (simplified):
* If `NOT_PRESENT` and no conflicting evidence → `NOT_PRESENT`.
* If at least one affected symbol is on a static path from any entrypoint → `STATICALLY_REACHABLE`.
* If symbol observed at runtime → `RUNTIME_OBSERVED` (top state).
* If symbol present in binary but not on any static path → `PRESENT_NOT_REACHABLE`, unless unknown edges exist near it (then downgrade with lower confidence).
* Unknowns Registry entries near affected symbols increase `unknowns_pressure` and may push from `NOT_PRESENT` to `UNKNOWN`.
Implementation: pure functional merge functions inside Scanner.WebService:
```csharp
ReachabilityState Merge(ReachabilityState a, ReachabilityState b);
ReachabilityState FromEvidence(StaticEvidence s, RuntimeEvidence r, UnknownsPressure u);
```
#### 4.3.3. Deterministic inputs
To guarantee replay:
* Build **Reachability Plan Manifest** per run:
```json
{
"plan_id": "reach:sha256:…",
"scanner_version": "1.4.0",
"analyzers": {
"binary_discovery": "1.0.0",
"binary_symbolizer": "1.1.0",
"binary_callgraph": "1.2.0"
},
"inputs": {
"image_digest": "sha256:…",
"runtime_trace_files": ["signals:run:2025-11-18T12:00:00Z"],
"config": {
"assume_indirect_calls": "conservative",
"max_call_depth": 10
}
}
}
```
* DSSE-sign the plan + result.
---
### 4.4. Storage and graph overlay
#### 4.4.1. Reachability store
Backend: re-use existing Scanner/Cartographer storage stack (e.g., Postgres or SQLite + blob store).
Tables/collections:
* `reachability_runs`
* `plan_id`, `image_ref`, `created_at`, `scanner_version`.
* `reachability_results`
* `plan_id`, `cve_id`, `purl`, `state`, `confidence_p`, `unknowns_pressure`, `payload_json`.
* Indexes on `(image_ref, cve_id)`, `(image_ref, purl)`.
#### 4.4.2. Cartographer overlay
Edges:
* `IMAGE` → `BINARY` → `FUNCTION` → `PACKAGE` → `CVE`
* Extra property on `IMAGE -[AFFECTED_BY]-> CVE`:
* `reachability_state`
* `reachability_plan_id`
Enables queries:
* “Show me all CVEs with `STATICALLY_REACHABLE` in this namespace.”
* “Show me binaries with high density of reachable crypto CVEs.”
---
### 4.5. APIs (idempotent, additive)
#### 4.5.1. Trigger reachability
`POST /reachability/runs`
Request:
```json
{
"artifact": { "type": "oci.image", "ref": "registry/app@sha256:…" },
"config": {
"include_languages": ["binary"],
"max_call_depth": 10,
"assume_indirect_calls": "conservative"
}
}
```
Response:
```json
{ "plan_id": "reach:sha256:…" }
```
* Idempotent key: `(image_ref, config_hash)`. Subsequent calls return same `plan_id`.
#### 4.5.2. Fetch results
`GET /reachability/runs/:plan_id`
```json
{
"plan": { /* reachability plan manifest */ },
"results": [
{
"cve_id": "CVE-2025-12345",
"purl": "pkg:apk/alpine/openssl@3.1.5-r2",
"reachability_state": "static_reachable",
"confidence": { "p": 0.84, "unknowns_pressure": 0.1 }
}
]
}
```
#### 4.5.3. Per-CVE view for VEXer/Excitor
`GET /reachability/by-cve?artifact=…&cve_id=…`
* Returns filtered result for downstream VEX creation.
All APIs are **read-only** except for the side effect of storing/caching runs.
---
## 5. Interaction with other Stella Ops modules
### 5.1. Concelier
* Provides:
* CVE→purl→symbol mapping.
* Vendor VEX statements indicating affected functions.
* Consumes:
* Nothing from reachability directly; Scanner/WebService passes reachability summary to VEXer/Excitor which merges with vendor statements.
### 5.2. VEXer / Excitor
* Input:
* For each `(artifact, cve)`:
* Reachability state.
* Confidence.
* Logic:
* Translate states to VEX statements:
* `NOT_PRESENT` → `not_affected`
* `PRESENT_NOT_REACHABLE` → `not_affected` (with justification “code not reachable according to analysis”)
* `STATICALLY_REACHABLE` → `affected`
* `RUNTIME_OBSERVED` → `affected` (higher severity)
* Attach determinism proof:
* Plan ID + DSSE of reachability run.
### 5.3. Signals
* Provides:
* Function hit events: `(binary_id, function_id, timestamp)` aggregated per image.
* Reachability Engine:
* Marks `runtime_hits` and state `RUNTIME_OBSERVED` for symbols with hits.
* Unknowns:
* If runtime sees hits in functions with no static edges to entrypoints (or unmapped symbols), these produce Unknowns and increase `unknowns_pressure`.
### 5.4. Unknowns Registry
* From reachability pipeline, create Unknowns when:
* Symbol→package mapping is ambiguous.
* CVE→symbol mapping exists, but symbol cannot be found in binaries.
* Call graph has indirect calls that cannot be resolved.
* The “Unknowns Pressure” term is fed into:
* Reachability confidence.
* Global risk scoring (Trust Algebra Studio).
---
## 6. Implementation phases and engineering plan
### Phase 0 – Scaffolding & manifests (1 sprint)
* Create:
* `StellaOps.Reachability.Engine` skeleton.
* Reachability Plan Manifest schema.
* Reachability Run + Result persistence.
* Add `/reachability/runs` and `/reachability/runs/:plan_id` endpoints, returning mock data.
* Wire DSSE attestation generation for reachability results (even if payload is empty).
### Phase 1 – Binary discovery + symbolization (1–2 sprints)
* Implement `Binary.Discovery` and `Binary.Symbolizer`.
* Feed symbol tables into Reachability Engine as “presence-only evidence”:
* States: `NOT_PRESENT` vs `PRESENT_NOT_REACHABLE` vs `UNKNOWN`.
* Integrate with Concelier’s CVE→purl mapping (no symbol-level yet):
* For CVEs affecting a package present in the image, mark as `PRESENT_NOT_REACHABLE`.
* Emit Unknowns for unresolved binary roles and ambiguous package mapping.
Deliverable: package-level reachability with deterministic manifests.
### Phase 2 – Binary call graphs & entrypoints (2–3 sprints)
* Implement `Binary.CallGraph.Native`:
* CFG + direct call edges.
* Implement entrypoint inference from binary + container ENTRYPOINT/CMD.
* Add static reachability algorithm:
* DFS/BFS from entrypoints through call graph.
* Mark affected symbols as reachable if found on paths.
* Extend Concelier to ingest symbol-aware vulnerability metadata (for pilots; can be partial).
Deliverable: function-level static reachability for native binaries where symbol maps exist.
### Phase 3 – Runtime integration (2 sprints, may be in parallel workstream)
* Integrate Signals runtime evidence:
* Define schema for function hit events.
* Add ingestion path into Reachability Engine.
* Update lattice:
* Promote symbols to `RUNTIME_OBSERVED` when hits exist.
* Extend DSSE attestation to reference runtime evidence URIs (hashes of trace inputs).
Deliverable: static + runtime-confirmed reachability.
### Phase 4 – Unknowns & pressure (1 sprint)
* Wire Unknowns Registry:
* Emit unknowns from Symbolizer and CallGraph (identity gaps, missing edges).
* Compute `unknowns_pressure` per `(artifact, cve)` as density of unknowns near affected symbols.
* Adjust confidence calculation in Reachability Engine.
* Expose unknowns metrics in API and Cartographer.
Deliverable: explicit modelling of uncertainty, feeding into trust/lattice.
### Phase 5 – Language extensions (JS/Python/PHP) (ongoing)
* Implement per-language call-graph analyzers creating the same IR as binary.
* Extend symbol→purl mapping for these ecosystems (npm, PyPI, Packagist).
* Update reachability solver to include multi-language edges (e.g., Python calling into native modules).
---
## 7. Minimal contracts for agents
To hand off to agents, you can codify:
1. **IR schemas**
* Call graph IR.
* Reachability Result JSON.
* Reachability Plan Manifest.
2. **API contracts**
* `POST /reachability/runs`
* `GET /reachability/runs/:plan_id`
* `GET /reachability/by-cve`
3. **Module boundaries**
* `Scanner.Analyzers.Binary.*` produce IR only; NO network calls.
* `Reachability.Engine` is the only place where lattice logic lives.
* `Concelier` is read-only for reachability; no custom logic there.
4. **Determinism practices**
* All algorithmic randomness is banned; where unavoidable, seed with values derived from plan_id.
* All external inputs must be listed in the Plan Manifest.
If you like, next step I can draft:
* Concrete C# record types for the IRs.
* A small pseudo-code implementation of the lattice functions and static reachability DFS.
* A proposed directory layout under `src/StellaOps.Scanner` and `src/StellaOps.Cartographer`.

Here’s a simple, cheap way to sanity‑check your vuln function recovery without fancy ground truth: **build “patch oracles.”**
---
### What it is (in plain words)
Take a known CVE and compile two **tiny** binaries from the same source:
* **Vulnerable** commit/revision
* **Fixed** commit/revision
Then diff the discovered functions + call edges between the two. If your analyzer can’t see the symbol (or guard) the patch adds/removes/tightens, your recall is suspect.
---
### Why it works
Patches for real CVEs usually:
* add/remove a **function** (e.g., `validate_len`)
* change a **call site** (new guard before `memcpy`)
* tweak **control flow** (early return on bounds check)
Those are precisely the things your function recovery / call‑graph pass should surface—even on stripped ELFs. If they don’t move in your graph, you’ve got blind spots.
---
### Minimal workflow (5 steps)
1. **Pick a CVE** with a clean, public fix (e.g., OpenSSL/zlib/busybox).
2. **Isolate the patch** (git range or cherry‑pick) and craft a *tiny harness* that calls the affected code path.
3. **Build both** with the same toolchain/flags; produce **stripped** ELFs (`-s`) to mimic production.
4. **Run your discovery** on both:
* function list, demangled where possible
* call edges (A→B), basic blocks (optional)
5. **Diff the graphs**: look for the new guard function, removed unsafe call, or altered edge count.
---
### A tiny “oracle spec” (drop-in YAML for your test runner)
```yaml
cve: CVE-YYYY-XXXX
target: libfoo 1.2.3
build:
cc: clang
cflags: [-O2, -fno-omit-frame-pointer]
ldflags: []
strip: true
evidence:
expect_functions_added: [validate_len]
expect_functions_removed: [unsafe_copy] # optional
expect_call_added:
- caller: foo_parse
callee: validate_len
expect_call_removed:
- caller: foo_parse
callee: memcpy
tolerances:
allow_unresolved_symbols: 0
allow_extra_funcs: 2
```
---
### Quick harness pattern (C)
```c
// before: foo_parse -> memcpy(buf, src, len);
// after : foo_parse -> validate_len(len) -> memcpy(...)
extern int foo_parse(const char*);
int main(int argc, char** argv) {
const char* in = argc > 1 ? argv[1] : "AAAA";
return foo_parse(in);
}
```
---
### What to flag as a failure
* Expected **function not discovered** (e.g., `validate_len` missing).
* Expected **edge not present** (`foo_parse → validate_len` absent).
* **No CFG change** where patch clearly adds a guard/early return.
---
### Where this plugs into Stella Ops
* Put these oracles under `Scanner/tests/patch-oracles/*` per language.
* Run them in CI for **.NET/JVM/C/C++/Go/Rust** analyzers.
* Use them to gate any changes to symbolization, demangling, or call‑graph building.
* Record per‑analyzer **recall deltas** when you tweak heuristics or switch disassemblers.
---
If you want, I can scaffold the first three oracles (e.g., zlib overflow fix, OpenSSL length check, BusyBox `ash` patch) with ready‑to‑run Makefiles and expected graph diffs.
Understood — let us turn the “patch oracle” idea into something you can actually drop into the Stella Ops repo and CI.
I will walk through:
1. How to structure this inside the monorepo
2. How to build one oracle end-to-end (C/C++ example)
3. How to do the same for .NET/JVM
4. How to automate running and asserting them
5. Practical rules and pitfalls so these stay stable and useful
---
## 1. Where this lives in Stella Ops
A simple, language-agnostic layout that will scale:
```text
src/
StellaOps.Scanner/
... # your scanner code
StellaOps.Scanner.Tests/ # existing tests (if any)
PatchOracles/
c/
CVE-YYYY-XXXX-<short-name>/
src/
build.sh
oracle.yml
README.md
cpp/
...
dotnet/
CVE-YYYY-XXXX-<short-name>/
src/
build.ps1
oracle.yml
README.md
jvm/
...
go/
...
rust/
...
tools/
scanner-oracle-runner/ # tiny runner (C# console or bash)
```
Key principles:
* Each CVE/test case is **self-contained** (its own folder with sources, build script, oracle.yml).
* Build scripts produce **two binaries/artifacts**: `vuln` and `fixed`.
* `oracle.yml` describes: how to build, what to scan, and what differences to expect in Scanner’s call graph/function list.
---
## 2. How to build a single patch oracle (C/C++)
Think of a patch oracle as: “Given these two binaries, Scanner must see specific changes in functions and call edges.”
### 2.1. Step-by-step workflow
For one C/C++ CVE:
1. **Pick & freeze the patch**
* Choose a small, clean CVE in a library with easily buildable code (zlib, OpenSSL, BusyBox, etc.).
* Identify commit `A` (vulnerable) and commit `B` (fixed).
* Extract only the minimal sources needed to build the affected function + a harness into `src/`.
2. **Create a minimal harness**
Example: patch adds `validate_len` and guards a `memcpy` in `foo_parse`.
```c
// src/main.c
#include <stdio.h>
int foo_parse(const char* in); // from the library code under test
int main(int argc, char** argv) {
const char* in = (argc > 1) ? argv[1] : "AAAA";
return foo_parse(in);
}
```
Under `src/`, you keep two sets of sources:
```text
src/
vuln/
foo.c # vulnerable version
api.h
main.c
fixed/
foo.c # fixed version (adds validate_len, changes calls)
api.h
main.c
```
3. **Provide a deterministic build script**
Example `build.sh`:
```bash
#!/usr/bin/env bash
set -euo pipefail
CC="${CC:-clang}"
CFLAGS="${CFLAGS:- -O2 -fno-omit-frame-pointer -g0}"
LDFLAGS="${LDFLAGS:- }"
build_one() {
local name="$1" # vuln or fixed
mkdir -p build
${CC} ${CFLAGS} src/${name}/*.c ${LDFLAGS} -o build/${name}
# Strip symbols to simulate production
strip build/${name}
}
build_one "vuln"
build_one "fixed"
```
Guidelines:
* Fix the toolchain: either run this inside a Docker image (e.g., `debian:bookworm` with specific `clang` version) or at least document required versions in `README.md`.
* Always build both artifacts with **identical flags**; the only difference should be the code change.
* Use `strip` to ensure Scanner doesn’t accidentally rely on debug symbols.
4. **Define the oracle (what must change)**
You define expectations based on the patch:
* Functions added/removed/renamed.
* New call edges (e.g., `foo_parse -> validate_len`).
* Removed call edges (e.g., `foo_parse -> memcpy`).
* Optionally: new basic blocks, conditional branches, or early returns.
A practical `oracle.yml` for this case:
```yaml
cve: CVE-YYYY-XXXX
name: zlib_len_guard_example
language: c
toolchain:
cc: clang
cflags: "-O2 -fno-omit-frame-pointer -g0"
ldflags: ""
build:
script: "./build.sh"
artifacts:
vulnerable: "build/vuln"
fixed: "build/fixed"
scan:
scanner_cli: "dotnet run --project ../../StellaOps.Scanner.Cli"
# If you have a Dockerized scanner, you could do:
# scanner_cli: "docker run --rm -v $PWD:/work stellaops/scanner:dev"
args:
- "--format=json"
- "--analyzers=native"
timeout_seconds: 120
expectations:
functions:
must_exist_in_fixed:
- name: "validate_len"
must_not_exist_in_vuln:
- name: "validate_len"
calls:
must_add:
- caller: "foo_parse"
callee: "validate_len"
must_remove:
- caller: "foo_parse"
callee: "memcpy"
tolerances:
allow_unresolved_symbols: 0
allow_extra_functions: 5
allow_missing_calls: 0
```
5. **Connect Scanner output to the oracle**
Assume your Scanner CLI produces something like:
```json
{
"binary": "build/fixed",
"functions": [
{ "name": "foo_parse", "address": "0x401000" },
{ "name": "validate_len", "address": "0x401080" },
...
],
"calls": [
{ "caller": "foo_parse", "callee": "validate_len" },
{ "caller": "validate_len", "callee": "memcpy" }
]
}
```
Your oracle-runner will:
* Run scanner on `vuln` → `vuln.json`
* Run scanner on `fixed` → `fixed.json`
* Compare each expectation in `oracle.yml` against `vuln.json` and `fixed.json`
Pseudo-logic for a function expectation:
```csharp
bool HasFunction(JsonElement doc, string name) =>
doc.GetProperty("functions")
.EnumerateArray()
.Any(f => f.GetProperty("name").GetString() == name);
bool HasCall(JsonElement doc, string caller, string callee) =>
doc.GetProperty("calls")
.EnumerateArray()
.Any(c =>
c.GetProperty("caller").GetString() == caller &&
c.GetProperty("callee").GetString() == callee);
```
The runner will produce a small report, per oracle:
```text
[PASS] CVE-YYYY-XXXX zlib_len_guard_example
+ validate_len appears only in fixed → OK
+ foo_parse → validate_len call added → OK
+ foo_parse → memcpy call removed → OK
```
If anything fails, it prints the mismatches and exits with non-zero code so CI fails.
---
## 3. Implementing the oracle runner (practical variant)
You can implement this either as:
* A standalone C# console (`StellaOps.Scanner.PatchOracleRunner`), or
* A set of xUnit tests that read `oracle.yml` and run dynamically.
### 3.1. Console runner skeleton (C#)
High-level structure:
```text
src/tools/scanner-oracle-runner/
Program.cs
Oracles/
(symlink or reference to src/StellaOps.Scanner.Tests/PatchOracles)
```
Core responsibilities:
1. Discover all `oracle.yml` files under `PatchOracles/`.
2. For each:
* Run the `build` script.
* Run the scanner on both artifacts.
* Evaluate expectations.
3. Aggregate results and exit with appropriate status.
Pseudo-code outline:
```csharp
static int Main(string[] args)
{
var root = args.Length > 0 ? args[0] : "src/StellaOps.Scanner.Tests/PatchOracles";
var oracleFiles = Directory.GetFiles(root, "oracle.yml", SearchOption.AllDirectories);
var failures = new List<string>();
foreach (var oracleFile in oracleFiles)
{
var result = RunOracle(oracleFile);
if (!result.Success)
{
failures.Add($"{result.Name}: {result.FailureReason}");
}
}
if (failures.Any())
{
Console.Error.WriteLine("Patch oracle failures:");
foreach (var f in failures) Console.Error.WriteLine(" - " + f);
return 1;
}
Console.WriteLine("All patch oracles passed.");
return 0;
}
```
`RunOracle` does:
* Deserialize YAML (e.g., via `YamlDotNet`).
* `Process.Start` for `build.script`.
* `Process.Start` for `scanner_cli` twice (vuln/fixed).
* Read/parse JSON outputs.
* Run checks `functions.must_*` and `calls.must_*`.
This is straightforward plumbing code; once built, adding a new patch oracle is just adding a folder + `oracle.yml`.
---
## 4. Managed (.NET / JVM) patch oracles
Exact same concept, slightly different mechanics.
### 4.1. .NET example
Directory:
```text
PatchOracles/
dotnet/
CVE-2021-XXXXX-systemtextjson/
src/
vuln/
Example.sln
Api/...
fixed/
Example.sln
Api/...
build.ps1
oracle.yml
```
`build.ps1` (PowerShell, simplified):
```powershell
param(
[string]$Configuration = "Release"
)
$ErrorActionPreference = "Stop"
function Build-One([string]$name) {
Push-Location "src/$name"
dotnet clean
dotnet publish -c $Configuration -p:DebugType=None -p:DebugSymbols=false -o ../../build/$name
Pop-Location
}
New-Item -ItemType Directory -Force -Path "build" | Out-Null
Build-One "vuln"
Build-One "fixed"
```
`oracle.yml`:
```yaml
cve: CVE-2021-XXXXX
name: systemtextjson_escape_fix
language: dotnet
build:
script: "pwsh ./build.ps1"
artifacts:
vulnerable: "build/vuln/Api.dll"
fixed: "build/fixed/Api.dll"
scan:
scanner_cli: "dotnet run --project ../../StellaOps.Scanner.Cli"
args:
- "--format=json"
- "--analyzers=dotnet"
timeout_seconds: 120
expectations:
methods:
must_exist_in_fixed:
- "Api.JsonHelper::EscapeString"
must_not_exist_in_vuln:
- "Api.JsonHelper::EscapeString"
calls:
must_add:
- caller: "Api.Controller::Handle"
callee: "Api.JsonHelper::EscapeString"
tolerances:
allow_missing_calls: 0
allow_extra_methods: 10
```
Scanner’s .NET analyzer should produce method identifiers in a stable format (e.g., `Namespace.Type::Method(Signature)`), which you then use in the oracle.
### 4.2. JVM example
Similar structure, but artifacts are JARs:
```yaml
build:
script: "./gradlew :app:assemble"
artifacts:
vulnerable: "app-vuln.jar"
fixed: "app-fixed.jar"
scan:
scanner_cli: "dotnet run --project ../../StellaOps.Scanner.Cli"
args:
- "--format=json"
- "--analyzers=jvm"
```
Expectations then refer to methods like `com.example.JsonHelper.escapeString:(Ljava/lang/String;)Ljava/lang/String;`.
---
## 5. Wiring into CI
You can integrate this in your existing pipeline (GitLab Runner / Gitea / etc.) as a separate job.
Example CI job skeleton (GitLab-like YAML for illustration):
```yaml
patch-oracle-tests:
stage: test
image: mcr.microsoft.com/dotnet/sdk:10.0
script:
- dotnet build src/StellaOps.Scanner/StellaOps.Scanner.csproj -c Release
- dotnet build src/tools/scanner-oracle-runner/scanner-oracle-runner.csproj -c Release
- dotnet run --project src/tools/scanner-oracle-runner/scanner-oracle-runner.csproj -- \
src/StellaOps.Scanner.Tests/PatchOracles
artifacts:
when: on_failure
paths:
- src/StellaOps.Scanner.Tests/PatchOracles/**/build
- oracle-results.log
```
You can also:
* Tag the job (e.g., `oracle` or `reachability`) so you can run it nightly or on changes to Scanner analyzers.
* Pin Docker images with the exact C/C++/Java toolchains used by patch oracles so results are deterministic.
---
## 6. Practical guidelines and pitfalls
Here are concrete rules of thumb for making this robust:
### 6.1. Choosing good CVE oracles
Prefer cases where:
* The patch clearly adds/removes a **function** or **method**, or introduces a separate helper such as `validate_len`, `check_bounds`, etc.
* The patch adds/removes a **call** that is easy to see even under optimization (e.g., non-inline, non-template).
* The project is easy to build and not heavily reliant on obscure toolchains.
For each supported language in Scanner, target:
* 3–5 small C or C++ oracles.
* 3–5 .NET or JVM oracles.
* 1–3 for Go and Rust once those analyzers exist.
You do not need many; you want **sharp, surgical tests**, not coverage.
### 6.2. Handle inlining and optimization
Compilers may inline small functions; this can break naive “must have call edge” expectations.
Mitigations:
* Choose functions that are “large enough” or mark them `__attribute__((noinline))` (GCC/Clang) in your test harness code if necessary.
* Alternatively, relax expectations using `should_add` vs `must_add` for some edges:
```yaml
calls:
must_add: []
should_add:
- caller: "foo_parse"
callee: "validate_len"
```
In the runner, `should_add` failures can mark the oracle as “degraded” but not fatal, while `must_*` failures break the build.
### 6.3. Keep oracles stable over time
To avoid flakiness:
* **Vendor sources** into the repo (or at least snapshot the patch) so upstream changes do not affect builds.
* Pin toolchain versions in Docker images for CI.
* Capture and pin scanner configuration: analyzers enabled, rules, version. If you support “deterministic scan manifests” later, these oracles are perfect consumers of that.
### 6.4. What to assert beyond functions/calls
When your Scanner gets more advanced, you can extend `oracle.yml`:
```yaml
cfg:
must_increase_blocks:
- function: "foo_parse"
must_add_branch_on:
- function: "foo_parse"
operand_pattern: "len <= MAX_LEN"
```
Initially, I would keep it to:
* Function presence/absence
* Call edges presence/absence
and add CFG assertions only when your analyzers and JSON model for CFG stabilize.
### 6.5. How to use failures
When a patch oracle fails, it is a **signal** that either:
* A change in Scanner or a new optimization pattern created a blind spot, or
* The oracle is too strict (e.g., relying on a call that got inlined).
You then:
1. Inspect the disassembly / Scanner JSON for `vuln` and `fixed`.
2. Decide if Scanner is wrong (fix analyzer) or oracle is too rigid (relax to `should_*`).
3. Commit both the code change and updated oracle (if needed) in the same merge request.
---
## 7. Minimal checklist for adding a new patch oracle
For your future self and your agents, here is a compressed checklist:
1. Select CVE + patch; copy minimal affected sources into `src/…/<lang>/<CVE>/src/{vuln,fixed}`.
2. Add a tiny harness that calls the patched code path.
3. Write `build.sh` / `build.ps1` to produce `build/vuln` and `build/fixed` artifacts, stripped/Release.
4. Run manual `scanner` on both artifacts once; inspect JSON to find real symbol names and call edges.
5. Create `oracle.yml` with:
* `build.script` and `artifacts.*` paths
* `scan.scanner_cli` + args
* `expectations.functions.*` and `expectations.calls.*`
6. Run `scanner-oracle-runner` locally; fix any mismatches or over-strict expectations.
7. Commit and ensure CI job `patch-oracle-tests` runs and must pass on MR.
If you wish, next step we can design the actual JSON schema that Scanner should emit for function/call graphs and write a first C# implementation of `scanner-oracle-runner` aligned with that schema.

C-->G[POST /sbom/ingest]
F-->H[POST /attest/verify]
```
### What this does (in plain words)
* **Pull & crack the image** → extract layers, metadata (labels, env, history).
* **Build an SBOM** → emit **CycloneDX 1.6** and **SPDX 3.0.1** (pick one or both).
* **Sign artifacts** → wrap SBOM/provenance in **DSSE** envelopes.
* **Provenance** → generate **in‑toto Statement** with **SLSA Provenance v1** as the predicate.
* **Auditability** → optionally publish attestations to a transparency log (e.g., Rekor) so they’re tamper‑evident via Merkle proofs.
* **APIs are idempotent** → safe to re‑ingest the same image/SBOM/attestation without version churn.
### Design notes you can hand to an agent
* **Idempotency keys**
* `contentAddress` = SHA256 of OCI manifest (or full image digest)
* `sbomHash` = SHA256 of normalized SBOM JSON
* `attHash` = SHA256 of DSSE payload (base64‑stable)
Store these; reject duplicates with HTTP 200 + `"status":"already_present"`.
* **Default formats**
* SBOM export: CycloneDX v1.6 (`application/vnd.cyclonedx+json`), SPDX 3.0.1 (`application/spdx+json`)
* DSSE envelope: `application/dsse+json`
* in‑toto Statement: `application/vnd.in-toto+json` with `predicateType` = SLSA Provenance v1
* **Air‑gap mode**
* No external calls required; Rekor publish is optional.
* Keep a local Merkle log (pluggable) and allow later “sync‑to‑Rekor” when online.
* **Transparency log adapter**
* Interface: `Put(entry) -> {logIndex, logID, inclusionProof}`
* Backends: `rekor`, `local-merkle`, `null` (no‑op)
### Minimal API sketch
* `POST /sbom/ingest`
* Body: `{ imageDigest, sbom, format, dsseSignature? }`
* Returns: `{ sbomId, status, sbomHash }` (status: `stored|already_present`)
* `POST /attest/verify`
* Body: `{ dsseEnvelope, expectedSubjects:[{name, digest}] }`
* Verifies DSSE, checks in‑toto subject ↔ image digest, optionally records/logs.
* Returns: `{ verified:true, predicateType, logIndex?, inclusionProof? }`
### CLI flow (pseudocode)
```bash
# 1) Extract
stella-extract --image $IMG --out /work/extract
# 2) SBOM (Cdx + SPDX)
stella-sbomer cdx --in /work/extract --out /work/sbom.cdx.json
stella-sbomer spdx --in /work/extract --out /work/sbom.spdx.json
# 3) DSSE sign (offline keyring or HSM)
stella-sign dsse --in /work/sbom.cdx.json --out /work/sbom.cdx.dsse.json --key file:k.pem
# 4) SLSA provenance (in‑toto Statement)
stella-provenance slsa-v1 --subject $IMG_DIGEST --materials /work/extract/manifest.json \
--out /work/prov.dsse.json --key file:k.pem
# 5) (optional) Publish to transparency log
stella-log publish --in /work/prov.dsse.json --backend rekor --rekor-url $REKOR
```
### Validation rules (quick)
* **Subject binding**: in‑toto Statement `subject[].digest.sha256` must equal the OCI image digest you scanned.
* **Key policy**: enforce allowed issuers (Fulcio, internal CA, GOST/SM/EIDAS/FIPS as needed).
* **Normalization**: canonicalize JSON before hashing/signing to keep idempotency stable.
### Why this matters
* **Audit‑ready**: You can always prove *what* you scanned, *how* it was built, and *who* signed it.
* **Noise‑gated**: With deterministic SBOMs + provenance, downstream VEX/reachability gets much cleaner.
* **Drop‑in**: Works in harsh environments—offline, mirrors, sovereign crypto stacks—without changing your pipeline.
If you want, I can generate:
* a ready‑to‑use OpenAPI stub for `POST /sbom/ingest` and `POST /attest/verify`,
* C# (.NET 10) DSSE + in‑toto helpers (interfaces + test fixtures),
* or a Docker‑compose “air‑gap bundle” showing the full spine end‑to‑end.
Below is a full architecture plan you can hand to an agent as the “master spec” for implementing the SBOM & provenance spine (image → SBOM → DSSE → in-toto/SLSA → transparency log → REST APIs), with idempotent APIs and air-gap readiness.
---
## 1. Scope and Objectives
**Goal:** Implement a deterministic, air-gap-ready “SBOM spine” that:
* Converts OCI images into SBOMs (CycloneDX 1.6 and SPDX 3.0.1).
* Generates SLSA v1 provenance wrapped in in-toto Statements.
* Signs all artifacts with DSSE envelopes using pluggable crypto providers.
* Optionally publishes attestations to transparency logs (Rekor/local-Merkle/none).
* Exposes stable, idempotent APIs:
* `POST /sbom/ingest`
* `POST /attest/verify`
* Avoids versioning by design; APIs are extended, not versioned; all mutations are idempotent keyed by content digests.
**Out of scope (for this iteration):**
* Full vulnerability scanning (delegated to Scanner service).
* Policy evaluation / lattice logic (delegated to Scanner/Graph engine).
* Vendor-facing proof-market ledger and trust economics (future module).
---
## 2. High-Level Architecture

* Extraction of metadata (labels, env, history).
* Deterministic ordering & normalization.
3. **StellaOps.Provenance.Engine (Library)**
* Build provenance & in-toto:

## 5. End-to-End Flows
### 5.1 SBOM Ingest (Upload Path)
```mermaid
sequenceDiagram
participant Client
participant API as SupplyChain.Api
participant Core as SupplyChain.Core
participant DB as PostgreSQL
Client->>API: POST /sbom/ingest (imageDigest, sbom, format)
API->>Core: Validate & canonicalize SBOM
Core-->>API: sbomHash
API->>DB: SELECT Sbom WHERE sbomHash & imageDigest
DB-->>API: Not found
API->>DB: INSERT Sbom (sbomHash, imageDigest, content)
DB-->>API: ok
API-->>Client: 201 { status:"stored", sbomId, sbomHash }
```
Re-ingest of the same SBOM repeats steps up to SELECT, then returns `status:"already_present"` with `200`.
### 5.2 Attestation Verify & Record
```mermaid
sequenceDiagram
participant Client
participant API as SupplyChain.Api
participant Auth as Authority
participant Log as LogBridge
participant DB as PostgreSQL
Client->>API: POST /attest/verify (dsseEnvelope, expectedSubjects)
API->>Auth: Verify DSSE (keys, policy)
Auth-->>API: VerificationResult(Valid/Invalid)
API->>API: Parse in-toto, check subjects vs expected
API->>DB: SELECT Attestation WHERE attHash
DB-->>API: Not found
API->>DB: INSERT Attestation + SignatureInfo
alt Logging enabled
API->>Log: PutAsync(attHash, envelope)
Log-->>API: LogEntryResult(logIndex, logId, proof)
API->>DB: INSERT TransparencyLogEntry
end
API-->>Client: 201 { verified:true, attestationId, logIndex?, inclusionProof? }
```
If attestation already exists, API returns `200` with `status:"already_present"`.
---
## 6. Idempotency and Determinism Strategy
1. **Canonicalization rules:**
* Remove insignificant whitespace.
* Sort all object keys lexicographically.
* Sort arrays where order is not semantically meaningful (components, materials).
* Strip non-deterministic fields (timestamps, random IDs) where allowed.
2. **Hashing:**
* Always hash canonical JSON as UTF-8.
* Use SHA-256 for core IDs; allow crypto provider to also compute other digests if needed.
3. **Persistence:**
* Enforce uniqueness in DB via indices on:
* `(TenantId, ContentHash)` for SBOMs.
* `(TenantId, AttHash)` for attestations.
* `(Backend, LogId, LogIndex)` for log entries.
* API behavior:
* Existing row → `200` with `"already_present"`.
* New row → `201` with `"stored"`.
4. **API design:**
* No version numbers in path.
* Add fields over time; never break or repurpose existing ones.
* Use explicit capability discovery via `GET /meta/capabilities` if needed.
---
## 7. Air-Gap Mode and Synchronization
### 7.1 Air-Gap Mode
* Configuration flag `Mode = Offline` on SupplyChain.Api.
* LogBridge backend:
* Default to `LocalMerkle` or `Null`.
* Rekor-specific configuration disabled or absent.
* DB & Merkle log stored locally inside the secure network.
### 7.2 Later Synchronization to Rekor (Optional Future Step)
Not mandatory for first iteration, but prepare for:
* Background job (Scheduler module) that:
* Enumerates local `TransparencyLogEntry` not yet exported.
* Publishes hashed payloads to Rekor when network is available.
* Stores mapping between local log entries and remote Rekor entries.
---
## 8. Security, Access Control, and Observability
### 8.1 Security
* mTLS between internal services (SupplyChain.Api, Authority, LogBridge).
* Authentication:
* API keys/OIDC for clients.
* Per-tenant scoping; `TenantId` must be present in context.
* Authorization:
* RBAC: which tenants/users can write/verify/only read.
### 8.2 Crypto Policies
* Policy object defines:
* Allowed key types and algorithms.
* Trust roots (Fulcio, internal CA, sovereign PKI).
* Revocation checking strategy (CRL/OCSP, offline lists).
* Authority enforces policies; SupplyChain.Api only consumes `VerificationResult`.
### 8.3 Observability
* Logs:
* Structured logs with correlation IDs; log imageDigest, sbomHash, attHash.
* Metrics:
* SBOM ingest count, dedup hit rate.
* Attestation verify latency.
* Transparency log publish success/failure counts.
* Traces:
* OpenTelemetry tracing across API → Authority → LogBridge.

# Crypto Registry Decision · 2025-11-18
## Outcome
- Agree to ship `ICryptoProviderRegistry` with the following defaults:
- PreferredProviders (global default): `default`, `ru.openssl.gost`, `ru.pkcs11`.
- ActiveProfile for RU/sovereign deployments: `ru-offline` with preferred order `ru.cryptopro.csp`, `ru.openssl.gost`, `ru.pkcs11`.
- For non-RU deployments, ActiveProfile remains `default`.
- Registry contract to be published via shared library (`StellaOps.Cryptography` stack) and referenced by EvidenceLocker/ExportCenter/TimelineIndexer and downstream services.
- Deterministic config binding: keep profile names and provider IDs lowercase ASCII; enforce ISO-8601 UTC timestamps for any audit material generated by registry actions.
## Rationale
- Aligns with 2025-11-07 crypto routing audit (`docs/security/crypto-routing-audit-2025-11-07.md`) to ensure sovereign-ready providers are selectable without code changes.
- Keeps default provider chain intact for non-sovereign deployments while enabling RU-specific stacks where mandated.
## Required follow-ups
- Publish NuGet/package update exposing the approved registry contract and provider IDs.
- Update module hosts (EvidenceLocker, ExportCenter, TimelineIndexer, CLI) to bind `StellaOps:Crypto:Registry` using the defaults above.
- Add CI smoke to assert registry resolves the chosen ActiveProfile on Linux and Windows.
- Mirror decision into sprint docs for affected modules (160/161).

AngleSharp is a .NET library that gives you the ability to parse angle bracket based hyper-texts like HTML, SVG, and MathML. XML without validation is also supported by the library. An important aspect of AngleSharp is that CSS can also be parsed. The included parser is built upon the official W3C specification. This produces a perfectly portable HTML5 DOM representation of the given source code and ensures compatibility with results in evergreen browsers. Also standard DOM features such as `querySelector` or `querySelectorAll` work for tree traversal.
:zap::zap: **Migrating from AngleSharp 0.9 to AngleSharp 0.10 or later** (incl. 1.0)? Look at our [migration documentation](docs/tutorials/05-Migration.md). :zap::zap:
## Key Features
- **Portable** (using .NET Standard 2.0)
- **Standards conform** (works exactly as evergreen browsers)
- **Great performance** (outperforms similar parsers in most scenarios)
- **Extensible** (extend with your own services)
- **Useful abstractions** (type helpers, jQuery like construction)
- **Fully functional DOM** (all the lists, iterators, and events you know)
- **Form submission** (easily log in everywhere)
- **Navigation** (a `BrowsingContext` is like a browser tab - control it from .NET!).
- **LINQ enhanced** (use LINQ with DOM elements, naturally without wrappers)
The advantage over similar libraries like *HtmlAgilityPack* is that the exposed DOM is using the official W3C specified API, i.e., that even things like `querySelectorAll` are available in AngleSharp. Also the parser uses the HTML 5.1 specification, which defines error handling and element correction. The AngleSharp library focuses on standards compliance, interactivity, and extensibility. It is therefore giving web developers working with C# all possibilities as they know from using the DOM in any modern browser.
The performance of AngleSharp is quite close to the performance of browsers. Even very large pages can be processed within milliseconds. AngleSharp tries to minimize memory allocations and reuses elements internally to avoid unnecessary object creation.
## Simple Demo
The simple example will use the website of Wikipedia for data retrieval.
```cs
var config = Configuration.Default.WithDefaultLoader();
var address = "https://en.wikipedia.org/wiki/List_of_The_Big_Bang_Theory_episodes";
var context = BrowsingContext.New(config);
var document = await context.OpenAsync(address);
var cellSelector = "tr.vevent td:nth-child(3)";
var cells = document.QuerySelectorAll(cellSelector);
var titles = cells.Select(m => m.TextContent);
```
Or the same with explicit types:
```cs
IConfiguration config = Configuration.Default.WithDefaultLoader();
string address = "https://en.wikipedia.org/wiki/List_of_The_Big_Bang_Theory_episodes";
IBrowsingContext context = BrowsingContext.New(config);
IDocument document = await context.OpenAsync(address);
string cellSelector = "tr.vevent td:nth-child(3)";
IHtmlCollection<IElement> cells = document.QuerySelectorAll(cellSelector);
IEnumerable<string> titles = cells.Select(m => m.TextContent);
```
In the example we see:
* How to setup the configuration for supporting document loading
* Asynchronously get the document in a new context using the configuration
* Performing a query to get all cells with the content of interest
* The whole DOM supports LINQ queries
Every collection in AngleSharp supports LINQ statements. AngleSharp also provides many useful extension methods for element collections that cannot be found in the official DOM.
## Supported Platforms
AngleSharp has been created as a .NET Standard 2.0 compatible library. This includes, but is not limited to:
- .NET Core (2.0 and later)
- .NET Framework (4.6.1 and later)
- Xamarin.Android (7.0 and 8.0)
- Xamarin.iOS (10.0 and 10.14)
- Xamarin.Mac (3.0 and 3.8)
- Mono (4.6 and 5.4)
- UWP (10.0 and 10.0.16299)
- Unity (2018.1)
## Documentation
The documentation of AngleSharp is located [in the docs folder](docs/README.md). More examples, best-practices, and general information can be found there. The documentation also contains a list of [frequently asked questions](docs/tutorials/06-Questions.md).
More information is also available by following some of the hyper references mentioned in the Wiki. In-depth articles will be published on the CodeProject, with links being placed in the Wiki at GitHub.
## Use-Cases
- Parsing HTML (incl. fragments)
- Parsing CSS (incl. selectors, declarations, ...)
- Constructing HTML (e.g., view-engine)
- Minifying CSS, HTML, ...
- Querying document elements
- Crawling information
- Gathering statistics
- Web automation
- Tools with HTML / CSS / ... support
- Connection to page analytics
- HTML / DOM unit tests
- Automated JavaScript interaction
- Testing other concepts, e.g., script engines
- ...
## Vision
The project aims to bring a solid implementation of the W3C DOM for HTML, SVG, MathML, and CSS to the CLR - all written in C#. The idea is that you can basically do everything with the DOM in C# that you can do in JavaScript (plus, of course, more).
Most parts of the DOM are included, even though some may still miss their (fully specified / correct) implementation. The goal for v1.0 is to have *all practically relevant* parts implemented according to the official W3C specification (with useful extensions by the WHATWG).
The API is close to the DOM4 specification, however, the naming has been adjusted to apply with .NET conventions. Nevertheless, to make AngleSharp really useful for, e.g., a JavaScript engine, attributes have been placed on the corresponding interfaces (and methods, properties, ...) to indicate the status of the field in the official specification. This allows automatic generation of DOM objects with the official API.
This is a long-term project which will eventually result in a state of the art parser for the most important angle bracket based hyper-texts.
Our hope is to build a community around web parsing and libraries from this project. So far we had great contributions, but that goal was not fully achieved. Want to help? Get in touch with us!
## Participating in the Project
If you know some feature that AngleSharp is currently missing, and you are willing to implement the feature, then your contribution is more than welcome! Also if you have a really cool idea - do not be shy, we'd like to hear it.
If you have an idea how to improve the API (or what is missing) then posts / messages are also welcome. For instance there have been ongoing discussions about some styles that have been used by AngleSharp (e.g., `HTMLDocument` or `HtmlDocument`) in the past. In the end AngleSharp stopped using `HTMLDocument` (at least visible outside of the library). Now AngleSharp uses names like `IDocument`, `IHtmlElement` and so on. This change would not have been possible without such fruitful discussions.
The project is always searching for additional contributors. Even if you do not have any code to contribute, but rather an idea for improvement, a bug report or a mistake in the documentation. These are the contributions that keep this project active.
Live discussions can take place in our [Gitter chat](https://gitter.im/AngleSharp/AngleSharp), which supports using GitHub accounts.
More information is found in the [contribution guidelines](.github/CONTRIBUTING.md). All contributors can be found [in the CONTRIBUTORS](CONTRIBUTORS.md) file.
This project has also adopted the code of conduct defined by the Contributor Covenant to clarify expected behavior in our community.
For more information see the [.NET Foundation Code of Conduct](https://dotnetfoundation.org/code-of-conduct).
## Funding / Support
If you use AngleSharp frequently, but you do not have the time to support the project by active participation you may still be interested to ensure that the AngleSharp projects keeps the lights on.
Therefore we created a backing model via [Bountysource](https://salt.bountysource.com/teams/anglesharp). Any donation is welcome and much appreciated. We will mostly spend the money on dedicated development time to improve AngleSharp where it needs to be improved, plus invest in the web utility eco-system in .NET (e.g., in JavaScript engines, other parsers, or a renderer for AngleSharp to mention some outstanding projects).
> Visit [Bountysource](https://salt.bountysource.com/teams/anglesharp) for more details.
## Development
AngleSharp is written in the most recent version of C# and thus requires Roslyn as a compiler. Using an IDE like Visual Studio 2019+ is recommended on Windows. Alternatively, VSCode (with OmniSharp or another suitable Language Server Protocol implementation) should be the tool of choice on other platforms.
The code tries to be as clean as possible. Notably the following rules are used:
- Use braces for any conditional / loop body
- Use the `-Async` suffixed methods when available
- Use VIP ("Var If Possible") style (in C++ called AAA: Almost Always Auto) to place types on the right
More important, however, is the proper usage of tests. Any new feature should come with a set of tests to cover the functionality and prevent regression.
## Changelog
A very detailed [changelog](CHANGELOG.md) exists. If you are just interested in major releases then have a look at [the GitHub releases](https://github.com/AngleSharp/AngleSharp/releases).
