NOTIFY-SVC-39-002 marked DONE. | Implementer | +| 2025-11-27 | Completed correlation engine (NOTIFY-SVC-39-001): implemented `ICorrelationEngine`/`CorrelationEngine` that orchestrates key building, incident management, throttling, and quiet hours evaluation. Created `ICorrelationKeyBuilder` interface with `CompositeCorrelationKeyBuilder` (builds keys from tenant+kind+payload fields using SHA256 hashing) and `TemplateCorrelationKeyBuilder` (builds keys from template strings with variable substitution). Implemented `INotifyThrottler`/`InMemoryNotifyThrottler` with sliding window algorithm for rate limiting. Created `IQuietHoursEvaluator`/`QuietHoursEvaluator` supporting scheduled quiet hours (overnight windows, day-of-week filters, excluded event kinds, timezone support) and maintenance windows (tenant-scoped, event-kind filtering). Implemented `IIncidentManager`/`InMemoryIncidentManager` for incident lifecycle (Open→Acknowledged→Resolved) with correlation window support and reopen-on-new-event option. Added notification policies (FirstOnly, EveryEvent, OnEscalation, Periodic) with event count thresholds and severity escalation detection. DI registration via `AddCorrelationServices()` with `CorrelationServiceBuilder` for customization.

Implemented WebSocket live feed at `/api/v2/incidents/live` (`IncidentLiveFeed.cs`) with tenant-scoped subscriptions, broadcast methods (`BroadcastIncidentUpdateAsync`, `BroadcastStatsUpdateAsync`), ping/pong keep-alive, connection tracking. Fixed bug in `NotifyApiEndpoints.cs` where `ListPendingAsync` was called (method doesn't exist) - changed to use `QueryAsync`. Updated `Program.cs` to enable WebSocket middleware and map all v2 endpoints. Contract types renamed to avoid conflicts: `DeliveryAckRequest`, `DeliveryResponse`, `DeliveryStatsResponse`. | Implementer | +| 2025-11-27 | Completed REST APIs (NOTIFY-SVC-38-004): implemented `/api/v2/notify/rules` (GET list, GET by ID, POST create, PUT update, DELETE), `/api/v2/notify/templates` (GET list, GET by ID, POST create, DELETE, POST preview, POST validate), `/api/v2/notify/incidents` (GET list, POST ack, POST resolve). Created API contract DTOs: `RuleContracts.cs` (RuleCreateRequest, RuleUpdateRequest, RuleResponse, RuleMatchRequest/Response, RuleActionRequest/Response), `TemplateContracts.cs` (TemplatePreviewRequest/Response, TemplateCreateRequest, TemplateResponse), `IncidentContracts.cs` (IncidentListQuery, IncidentResponse, IncidentListResponse, IncidentAckRequest, IncidentResolveRequest). Endpoints registered via `MapNotifyApiV2()` extension method in `NotifyApiEndpoints.cs`. All mutations include audit logging. Tests at `NotifyApiEndpointsTests.cs`. NOTIFY-SVC-38-004 marked DONE. | Implementer | +| 2025-11-27 | Completed template service (NOTIFY-SVC-38-003): implemented `INotifyTemplateService`/`NotifyTemplateService` with locale fallback chain (exact locale → language-only → en-us default), template versioning via UpdatedAt timestamps, CRUD operations with audit logging. Created `EnhancedTemplateRenderer` with configurable redaction (safe/paranoid/none modes, allowlists/denylists), multi-format output (Markdown→HTML/PlainText conversion), provenance links, `{{#if}}` conditionals, and format specifiers (`{{var\|upper}}`, `{{var\|html}}`, etc.). Added `TemplateRendererOptions` for configuration. DI registration via `AddTemplateServices()` extension.

Effective priority formulas + +**Generic issues / tasks:** + +```csharp +double effectiveScore = issue.BasePriority * ConfidenceMath.ConfidenceScore(issue.LastSignalAt, issue.TauDays ?? defaultTau); +``` + +**Vulnerabilities (Stella Ops):** + +Let’s define: + +* `severity_weight`: map CVSS or severity string to numeric (e.g. Critical=100, High=80, Medium=50, Low=20). +* `reachability`: 0–1 (e.g. from your reachability analysis). +* `exploitability`: 0–1 (optional, based on known exploits). +* `confidence`: as above. + +```csharp +double baseRisk = severityWeight * reachability * exploitability; // or simpler: severityWeight * reachability +double conf = ConfidenceMath.ConfidenceScore(vuln.LastSignalAt, vuln.TauDays ?? defaultTau); +double effectiveRisk = baseRisk * conf; +``` + +Store `baseRisk` → `vulnerabilities.base_risk`, and compute `effectiveRisk` on the fly or via job. + +### 3.3.

Caching & performance + +You have two options: + +### 4.1.

If you see perf issues, move to 4.2. + +### 4.2. Periodic materialization job (optional later) + +Add a scheduled job (e.g. hourly) that: + +1. Selects all active items. +2. Computes `confidence_score` and `effective_priority`. +3. Writes to `confidence_cached` and `effective_priority_cached` (if you add such a column). + +Service then sorts by cached values. + +--- + +## 5. Backfill & migration + +### 5.1. Initial backfill script + +For existing records: + +* If `last_signal_at` is NULL → set to `created_at`. +* Derive `base_priority` / `base_risk` from existing severity fields. +* Set `tau_days` from config. + +**Example:** + +```sql +UPDATE issues +SET last_signal_at = created_at +WHERE last_signal_at IS NULL; + +UPDATE issues +SET base_priority = CASE severity + WHEN 'critical' THEN 100 + WHEN 'high' THEN 80 + WHEN 'medium' THEN 50 + WHEN 'low' THEN 20 + ELSE 10 +END +WHERE base_priority IS NULL; + +UPDATE issues i +SET tau_days = c.tau_days_default +FROM confidence_decay_config c +WHERE c.entity_type = 'issue' + AND i.tau_days IS NULL; +``` + +Do similarly for `vulnerabilities` using severity / CVSS. + +### 5.2. Sanity checks + +Add a small script/test to verify: + +* Newly created items → `confidence ≈ 1.0`. +* 30-day-old items with τ=30 → `confidence ≈ 0.37`. +* Ordering changes when you edit/comment on items. + +--- + +## 6.

([blog.sigstore.dev][1]) +* The global publicly‑distributed instance now supports only two entry types: `hashedrekord` (for artifacts) and `dsse` (for attestations). Many previously supported entry types — e.g. `intoto`, `rekord`, `helm`, `rfc3161`, etc. — have been removed. ([blog.sigstore.dev][1]) +* The log is now sharded: instead of a single growing Merkle tree, multiple “shards” (trees) are used. This supports better scaling, simpler rotation/maintenance, and easier querying by tree shard + identifier. ([Sigstore][2]) + +### ⚠️ Why this matters for attestations, and common pitfalls + +* Historically, when using DSSE or in‑toto style attestations submitted to Rekor (or via Cosign), the **entire attestation payload** had to be uploaded to Rekor. That becomes problematic when payloads are large. There’s a reported case where a 130 MB attestation was rejected due to size. ([GitHub][3]) +* The public instance of Rekor historically had a relatively small attestation size limit (on the order of 100 KB) for uploads. ([GitHub][4]) +* Because Rekor v2 no longer supports many entry types and simplifies the log types, you no longer have fallback for some of the older attestation/storage formats if they don’t fit DSSE/hashedrekord constraints. ([blog.sigstore.dev][1]) + +### ✅ What you must design for — and pragmatic workarounds + +Given your StellaOps architecture goals (deterministic builds, reproducible scans, large SBOMs/metadata, private/off‑air‑gap compliance), here’s what you should consider: + +* **Plan for payload-size constraints**: don’t assume arbitrary large attestations will be accepted. Keep attestation payloads small — ideally put large blobs (e.g. full SBOMs, large metadata) **outside** DSSE and store them elsewhere (artifact storage, internal logs, blob store) with the attestation only embedding a hash or reference. +* **Use “private logs” / self‑hosted Rekor** if you anticipate large payloads — public instance limits make heavy payload uploads impractical. Running your own instance gives you control over size limits and resource allocation. ([GitHub][4]) +* **Chunking / sharding**: For large metadata blobs, consider splitting (“sharding”) or chunking the data into smaller pieces, each with its own DSSE/hashed‑rekord entry, then reference or re‑assemble externally. This avoids hitting size limits while maintaining inclusion proofs. +* **Build idempotent re‑submit logic**: Because DSSE/hashed‑rekord entries are the only supported types, and large payloads may fail, your pipelines (e.g. StellaOps) should handle retries, partial submits, and ensure idempotence — so re‑submits don’t create inconsistent or duplicate entries. +* **Persist full attestations outside Rekor**: Since Rekor v2 dropped many types and doesn’t store full arbitrary blobs necessarily, ensure that the “source of truth” for large metadata remains under your control (e.g. in your internal storage), with Rekor only storing minimal hashed attestations. + +### 🎯 What this means for StellaOps + +For your “Proof‑of‑Integrity Graph” + “offline bundle + replayable scans” vision — this means you should treat Rekor (especially public) as a *lightweight ledger for proofs*, not as a full-blown metadata store. In practice: + +* Use Rekor for auditing, signature/inclusion proofs, and “commit‑to‑hash” attestations. +* Store full SBOMs, VEX data, scan metadata, large build/context blobs externally. +* Build your log‑sharding, replay, and artifact‑reference logic to survive Rekor’s constraints. +* For air‑gapped workflows, consider a private Rekor or alternative internal log that mirrors the public transparency‑log guarantees but under your control. + +If you like — I can pull up **real‑world examples** of organizations that already adapted to Rekor v2’s DSSE constraints (with chunking, private logs, hybrid storage) — could help shape StellaOps resilience strategy. + +[1]: https://blog.sigstore.dev/rekor-v2-ga/?utm_source=chatgpt.com "Rekor v2 GA - Cheaper to run, simpler to maintain" +[2]: https://docs.sigstore.dev/logging/sharding/?utm_source=chatgpt.com "Sharding" +[3]: https://github.com/sigstore/cosign/issues/3599?utm_source=chatgpt.com "Attestations require uploading entire payload to rekor #3599" +[4]: https://github.com/sigstore/rekor?utm_source=chatgpt.com "sigstore/rekor: Software Supply Chain Transparency Log" +Here’s a concrete, developer‑friendly implementation plan you can hand to the team. I’ll assume the context is “StellaOps + Sigstore/Rekor v2 + DSSE + air‑gapped support”. + +--- + +## 0. Shared context & constraints (what devs should keep in mind) + +**Key facts (summarized):** + +* Rekor v2 keeps only **two** entry types: `hashedrekord` (artifact signatures) and `dsse` (attestations). Older types (`intoto`, `rekord`, etc.) are gone. ([Sigstore Blog][1]) +* The **public** Rekor instance enforces a ~**100KB attestation size limit** per upload; bigger payloads must use your **own Rekor instance** instead. ([GitHub][2]) +* For DSSE entries, Rekor **does not store the full payload**; it stores hashes and verification material. Users are expected to persist the attestations alongside artifacts in their own storage. ([Go Packages][3]) +* People have already hit problems where ~130MB attestations were rejected by Rekor, showing that “just upload the whole SBOM/provenance” is not sustainable. ([GitHub][4]) +* Sigstore’s **bundle** format is the canonical way to ship DSSE + tlog metadata around as a single JSON object (very useful for offline/air‑gapped replay). ([Sigstore][5]) + +**Guiding principles for the implementation:** + +1. **Rekor is a ledger, not a blob store.** We log *proofs* (hashes, inclusion proofs), not big documents. +2. **Attestation payloads live in our storage** (object store / DB). +3. **All Rekor interaction goes through one abstraction** so we can easily switch public/private/none. +4. **Everything is idempotent and replayable** (important for retries and air‑gapped exports). + +--- + +## 1. High‑level architecture + +### 1.1 Components + +1. **Attestation Builder library (in CI/build tools)** + + * Used by build pipelines / scanners / SBOM generators. + * Responsibilities: + + * Collect artifact metadata (digest, build info, SBOM, scan results). + * Call Attestation API (below) with **semantic info** and raw payload(s). + +2. **Attestation Service (core backend microservice)** + + * Single entry‑point for creating and managing attestations. + * Responsibilities: + + * Normalize incoming metadata. + * Store large payload(s) in object store. + * Construct **small DSSE envelope** (payload = manifest / summary, not giant blob). + * Persist attestation records & payload manifests in DB. + * Enqueue log‑submission jobs for: + + * Public Rekor v2 + * Private Rekor v2 (optional) + * Internal event log (DB/Kafka) + * Produce **Sigstore bundles** for offline use. + +3. **Log Writer / Rekor Client Worker(s)** + + * Background workers consuming submission jobs. + * Responsibilities: + + * Submit `dsse` (and optionally `hashedrekord`) entries to configured Rekor instances. + * Handle retries with backoff. + * Guarantee idempotency (no duplicate entries, no inconsistent state). + * Update DB with Rekor log index/uuid and status. + +4. **Offline Bundle Exporter (CLI or API)** + + * Runs in air‑gapped cluster. + * Responsibilities: + + * Periodically export “new” attestations + bundles since last export. + * Materialize data as tar/zip with: + + * Sigstore bundles (JSON) + * Chunk manifests + * Large payload chunks (optional, depending on policy). + +5. **Offline Replay Service (connected environment)** + + * Runs where internet access and public Rekor are available. + * Responsibilities: + + * Read offline bundles from incoming location. + * Replay to: + + * Public Rekor + * Cloud storage + * Internal observability + * Write updated status back (e.g., via a status file or callback). + +6. **Config & Policy Layer** + + * Central (e.g. YAML, env, config DB). + * Controls: + + * Which logs to use: `public_rekor`, `private_rekor`, `internal_only`. + * Size thresholds (DSSE payload limit, chunk size). + * Retry/backoff policy. + * Air‑gapped mode toggles. + +--- + +## 2.

DSSE payload design (how to avoid size limits) + +### 3.1 Manifest‑based DSSE instead of giant payloads + +Instead of DSSE‑signing the **entire SBOM/provenance blob** (which hits Rekor’s 100KB limit), we sign a **manifest** describing where the payload lives and how to verify it. + +**Example manifest JSON** (payload of DSSE, small): + +```json +{ + "version": "stellaops.manifest.v1", + "subject": { + "uri": "registry.example.com/app@sha256:abcd...", + "digest": "sha256:abcd..." + }, + "payload": { + "type": "sbom.spdx+json", + "rootDigest": "sha256:deadbeef...", + "totalSize": 73400320, + "chunkCount": 12 + }, + "chunks": [ + { + "index": 0, + "digest": "sha256:1111...", + "size": 6291456 + }, + { + "index": 1, + "digest": "sha256:2222...", + "size": 6291456 + } + // ... + ], + "storagePolicy": { + "backend": "s3", + "bucket": "stellaops-attestations", + "pathPrefix": "sboms/app/abcd..." + } +} +``` + +* This JSON is small enough to **fit under 100KB** even with lots of chunks, so the DSSE envelope stays small. +* Full SBOM/scan results live in your object store; Rekor logs the DSSE envelope hash. + +### 3.2 Chunking logic (Attestation Service) + +Config values (can be env vars): + +* `CHUNK_SIZE_BYTES` = e.g. 5–10 MiB +* `MAX_DSSE_PAYLOAD_BYTES` = e.g. 70 KiB (keeping margin under Rekor 100KB limit) +* `MAX_CHUNK_COUNT` = safety guard + +Algorithm: + +1. Receive raw payload bytes (SBOM / provenance / scan results). +2. Compute full `root_digest = sha256(payload_bytes)` (or Merkle root if you want more advanced verification). +3. If `len(payload_bytes) <= SMALL_PAYLOAD_THRESHOLD` (e.g. 64 KB): + + * Skip chunking. + * Store payload as single object. + * Manifest can optionally omit `chunks` and just record one object. +4. If larger: + + * Split into fixed‑size chunks (except last). + * For each chunk: + + * Compute `chunk_digest`. + * Upload chunk to object store path derived from `root_digest` + `chunk_index`. + * Insert `payload_chunks` rows. +5. Build manifest JSON with: + + * `version` + * `subject` + * `payload` block + * `chunks[]` (no URIs if you don’t want to leak details; the URIs can be derived by clients). +6. Check serialized manifest size ≤ `MAX_DSSE_PAYLOAD_BYTES`. If not: + + * Option A: increase chunk size so you have fewer chunks. + * Option B: move chunk list to a secondary “chunk index” document and sign only its root digest. +7. DSSE‑sign manifest JSON. +8. Persist DSSE envelope digest + manifest in DB. + +--- + +## 4. Rekor integration & idempotency + +### 4.1 Rekor client abstraction + +Implement an interface like: + +```ts +interface TransparencyLogClient { + submitDsseEnvelope(params: { + dsseEnvelope: Buffer; // JSON bytes + subjectDigest: string; + predicateType: string; + }): Promise<{ + logIndex: number; + logId: string; + entryUuid: string; + }>; +} +``` + +Provide implementations: + +* `PublicRekorClient` (points at `https://rekor.sigstore.dev` or v2 equivalent). +* `PrivateRekorClient` (your own Rekor v2 cluster). +* `NullClient` (for internal‑only mode). + +Use official API semantics from Rekor OpenAPI / SDKs where possible. ([Sigstore][6]) + +### 4.2 Submission jobs & idempotency + +**Submission key design:** + +```text +submission_key = sha256( + "dsse" + "|" + + rekor_base_url + "|" + + dsse_envelope_digest +) +``` + +Workflow in the worker: + +1. Worker fetches `log_submissions` with `state = 'pending'` or due for retry. +2. Set `state = 'in_progress'` (optimistic update). +3. Call `client.submitDsseEnvelope`. +4. If success: + + * Update `state = 'succeeded'`, set `rekor_log_index`, `rekor_log_id`. +5. If Rekor indicates “already exists” (or returns same logIndex for same envelope): + + * Treat as success, update `state = 'succeeded'`. +6. On network/5xx errors: + + * Increment `attempt_count`. + * If `attempt_count < MAX_RETRIES`: schedule retry with backoff. + * Else: `state = 'failed_permanent'`, keep `last_error`. + +DB constraint: `UNIQUE(target, submission_key)` ensures we don’t create conflicting jobs. + +--- + +## 5. Attestation Service API design + +### 5.1 Create attestation (build/scan pipeline → Attestation Service) + +**`POST /v1/attestations`** + +**Request body (example):** + +```json +{ + "subject": { + "uri": "registry.example.com/app@sha256:abcd...", + "digest": "sha256:abcd..." + }, + "payloadType": "sbom.spdx+json", + "payload": { + "encoding": "base64", + "data": "" + }, + "predicateType": "https://slsa.dev/provenance/v1", + "logTargets": ["internal", "private_rekor", "public_rekor"], + "airgappedMode": false, + "labels": { + "team": "payments", + "env": "prod" + } +} +``` + +**Server behavior:** + +1. Validate subject & payload. +2. Chunk payload as per rules (section 3). +3. Store payload chunks. +4. Build manifest JSON & DSSE envelope. +5. Insert `attestations`, `payload_manifests`, `payload_chunks`. +6. For each `logTargets`: + + * Insert `log_submissions` row with `state = 'pending'`. +7. Optionally construct Sigstore bundle representing: + + * DSSE envelope + * Transparency log entry (when available) — for async, you can fill this later. +8.

High-Level Architecture Changes + +1. **Introduce `graph_revision_id` as a first-class concept** in: + + * Graph storage / Authority + * Ledger / audit + * Backend APIs serving call graphs +2. **Derive `graph_revision_id` deterministically** from a manifest via a cryptographic hash. +3. **Expose revision in all graph-related URLs & APIs**: + + * UI: `…/graphs/{graph_id}?rev={graph_revision_id}` + * API: `…/api/graphs/{graph_id}/revisions/{graph_revision_id}` +4. **Ensure immutability**: once a revision exists, it can never be updated in-place—only superseded by new revisions. + +--- + +## 2. Backend: Data Model & Storage + +### 2.1. Authority (graph source of truth) + +**Goal:** Model graphs and revisions explicitly. + +**New / updated tables (example in SQL-ish form):** + +1. **Graphs (logical entity)** + +```sql +CREATE TABLE graphs ( + id UUID PRIMARY KEY, + created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(), + latest_revision_id VARCHAR(128) NULL, -- FK into graph_revisions.id + label TEXT NULL, -- optional human label + metadata JSONB NULL +); +``` + +2. **Graph Revisions (immutable snapshots)** + +```sql +CREATE TABLE graph_revisions ( + id VARCHAR(128) PRIMARY KEY, -- graph_revision_id (hash) + graph_id UUID NOT NULL REFERENCES graphs(id), + parent_revision_id VARCHAR(128) NULL REFERENCES graph_revisions(id), + created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(), + manifest JSONB NOT NULL, -- canonical manifest + provenance JSONB NOT NULL, -- tool versions, etc. + is_pinned BOOLEAN NOT NULL DEFAULT FALSE, + pinned_by UUID NULL, -- user id + pinned_at TIMESTAMPTZ NULL +); +CREATE INDEX idx_graph_revisions_graph_id ON graph_revisions(graph_id); +``` + +3. **Call Graph Data (if separate)** + If you store nodes/edges in separate tables, add a foreign key to `graph_revision_id`: + +```sql +ALTER TABLE call_graph_nodes + ADD COLUMN graph_revision_id VARCHAR(128) NULL; + +ALTER TABLE call_graph_edges + ADD COLUMN graph_revision_id VARCHAR(128) NULL; +``` + +> **Rule:** Nodes/edges for a revision are **never mutated**; a new revision means new rows. + +--- + +### 2.2.

Diff view (nice-to-have, can be v2) + +* UX: “Compare with…” button in header. + + * Opens dialog to pick a second revision. +* Backend: add a diff endpoint later, or compute diff client-side from node/edge lists if feasible. + +--- + +## 7. Migration Plan + +### 7.1. Phase 1 – Schema & read-path ready + +1. **Add DB columns/tables**: + + * `graphs`, `graph_revisions`, `graph_revision_ledger`. + * `graph_revision_id` column to `call_graph_nodes` / `call_graph_edges`. +2. **Deploy with no behavior changes**: + + * Default `graph_revision_id` columns NULL. + * Existing APIs continue to work. + +### 7.2. Phase 2 – Backfill existing graphs + +1. Write a **backfill job**: + + * For each distinct existing graph: + + * Build a manifest from existing stored data. + * Compute `graph_revision_id`. + * Insert into `graphs` & `graph_revisions`. + * Update nodes/edges for that graph to set `graph_revision_id`. + * Set `graphs.latest_revision_id`. + +2. Log any graphs that can’t be backfilled (corrupt data, etc.) for manual review. + +3. After backfill: + + * Add **NOT NULL** constraint on `graph_revision_id` for nodes/edges (if practical). + * Ensure all public APIs can fetch revisions without changes from clients. + +### 7.3. Phase 3 – Wire up new pipelines + +1. Update Scanner/Vexer to construct manifests and compute revision IDs. +2. Update Authority to accept `/internal/graphs/{graph_id}/revisions`. +3. Gradually roll out: + + * Feature flag: `graphRevisionIdFromPipeline`. + * For flagged runs, use the new pipeline; for others, fall back to old + synthetic revision. + +### 7.4. Phase 4 – Frontend rollout + +1. Update UI to: + + * Read `rev` from URL (but not required). + * Show `Rev` in header. + * Use revision-aware endpoints. +2. Once stable: + + * Update “Share” actions to always include `?rev=…`. + +--- + +## 8. Testing Strategy + +### 8.1. Unit tests + +* **Hashing library**: + + * Same manifest → same `graph_revision_id`. + * Different node ordering → same `graph_revision_id`. + * Tiny manifest change → different `graph_revision_id`. +* **Authority service**: + + * Creating a revision stores `graph_revisions` + nodes/edges with matching `graph_revision_id`. + * Duplicate revision (same id + manifest) is idempotent. + * Conflicting manifest with same `graph_revision_id` is rejected. + +### 8.2. Integration tests + +* Scenario: “Create graph → view in UI” + + * Pipeline produces manifest & revision. + * Authority persists revision. + * Ledger logs event. + * UI shows matching `graph_revision_id`. +* Scenario: “Stable permalinks” + + * Capture a link with `?rev=…`. + * Rerun pipeline (new revision). + * Old link still shows original nodes/edges. + +### 8.3. Migration tests + +* On a sanitized snapshot: + + * Run migration & backfill. + * Spot-check: + + * Each `graph_id` has exactly one `latest_revision_id`. + * Node/edge counts before and after match. + * Manually recompute hash for a few graphs and compare to stored `graph_revision_id`. + +--- + +## 9. Security & Compliance Considerations + +* **Immutability guarantee**: + + * Don’t allow updates to `graph_revisions.manifest`. + * Any change must happen by creating a new revision. +* **Tombstoning** (for rare delete cases): + + * If you must “remove” a bad graph, mark revision as `tombstoned` in an additional column and return `410 Gone` for that `graph_revision_id`. + * Never reuse that ID. +* **Access control**: + + * Ensure revision APIs use the same ACLs as existing graph APIs. + * Don’t leak manifests to users not allowed to see underlying artifacts. + +--- + +## 10.

([first.org][1]) +* The specification now clearly divides metrics into four groups: Base, Threat, Environmental, and Supplemental. ([first.org][1]) +* The National Vulnerability Database (NVD) has added support for CVSS v4.0 — meaning newer vulnerability records can carry v4‑style scores, vector strings and search filters. ([NVD][2]) +* What’s new/tangible: better granularity, explicit “Attack Requirements” and richer metadata to better reflect real‑world contextual risk. ([Seemplicity][3]) +* Why this matters: Enables more traceable evidence of how a score was derived (which metrics used, what context), supporting auditing, prioritisation and transparency. + +**Take‑away for your world**: If you’re leveraging vulnerability scanning, SBOM enrichment or compliance workflows (given your interest in SBOM/VEX/provenance), then moving to or supporting CVSS v4.0 ensures you have stronger traceability and richer scoring context that maps into policy, audit and remediation workflows. + +--- + +## 2.

([CycloneDX][4]) +* Key enhancements: *Cryptography Bill of Materials (CBOM)* support (listing algorithm families, elliptic curves, etc) and *structured citations* (who provided component info, how, when) to improve provenance. ([CycloneDX][4]) +* Provenance use‑cases: The spec enables declaring supplier/author/publisher metadata, component origin, external references. ([CycloneDX][5]) +* Broadening scope: CycloneDX now supports not just SBOM (software), but hardware BOMs (HBOM), machine learning BOMs, cryptographic BOMs (CBOM) and supports VEX/attestation use‑cases. ([openssf.org][6]) +* Why this matters: For your StellaOps architecture (with a strong emphasis on provenance, deterministic scans, trust‑frameworks) CycloneDX v1.7 provides native standard support for deeper audit‑ready evidence, cryptographic algorithm visibility (which matters for crypto‑sovereign readiness) and formal attestations/citations in the BOM. + +**Take‑away**: Aligning your SBOM/VEX/provenance stack (e.g., scanner.webservice) to output CycloneDX v1.7‑compliant artifacts means you jump ahead in terms of traceability, auditability and future‑proofing (crypto and IP). + +--- + +## 3.

([SLSA][7]) +* What’s new: Introduction of a *Source Track* (in addition to the Build Track) to capture source control provenance, distributed provenance, artifact attestations. ([SLSA][7]) +* Specification clarifies provenance/attestation formats, how builds should be produced, distributed, verified. ([SLSA][8]) +* Why this matters: SLSA gives you a standard framework for “I can trace this binary back to the code, the build system, the signer, the provenance chain,” which aligns directly with your strategic moats around deterministic replayable scans, proof‑of‑integrity graph, and attestations. + +**Take‑away**: If you integrate SLSA v1.2 (once finalised) into StellaOps, you gain an industry‑recognised standard for build provenance and attestation, complementing your SBOM/VEX and CVSS code bases. + +--- + +### Why I’m sharing this with you + +Given your interest in cryptographic‑sovereign readiness, deterministic scanning, provenance and audit‑grade supply‑chain tooling (your StellaOps moat list), this trifecta (CVSS v4.0 + CycloneDX v1.7 + SLSA v1.2) represents the major standards you need to converge on.

Ensure JSON is **additive** (backward compatible): + +* `via` is **non‑nullable** in responses from the new API version. +* If you must keep a legacy endpoint, add **v2** endpoints that guarantee `via`. + +3. Update OpenAPI spec: + +* Document `via.reason` as enum string, including allowed values. +* Document `via.provenance.detector`, `rule_id`, `confidence`. + +**Acceptance criteria:** + +* [ ] OpenAPI / Swagger shows `via.reason` as a string enum + description. +* [ ] New clients can deserialize edges with `via` without custom hacks. +* [ ] Old clients remain unaffected (either keep old endpoint or allow them to ignore `via`). + +--- + +## 2.

Replace all direct `new GraphEdge(...)` calls in source analyzers with these factories. + +**Acceptance criteria:** + +* [ ] Direct call edges produce `reason = static_call` with file:line evidence. +* [ ] Reflection/dynamic import edges use correct reasons and mark `confidence = medium` (or high where you’re certain). +* [ ] Unit tests check that for a known source file, the resulting edges contain expected `reason`, `evidence`, and `rule_id`. + +--- + +### 2.3 Binary / container analyzers + +**Owner:** Binary analysis / SCA team + +**Tasks:** + +1.

Wire up all binary edge creation to use this. + +**Acceptance criteria:** + +* [ ] For a test binary with a known relocation, edges include `reason = symbol_relocation` and section/symbol in evidence. +* [ ] No binary edge is created without `via`. + +--- + +## 3. Storage & migrations + +This depends on your backing store, but the pattern is similar. + +### 3.1 Relational (SQL) example + +**Owner:** Data / infra team + +**Tasks:** + +1.

Size Guardrail & Estimator (Ticket group C) + +This is the core safety net. + +### C1 – Implement JSON size estimator + +Language‑agnostic idea: + +```pseudo +function jsonBytes(payloadObject): int { + jsonString = JSON.stringify(payloadObject, no_whitespace) + return length(utf8_encode(jsonString)) +} +``` + +* Always **minify** (no pretty printing) for the final payload. +* Use UTF‑8 byte length, not character count. + +### C2 – DSSE + base64 size estimator + +Instead of guessing, **actually build the envelope** before upload: + +```pseudo +function buildDsseEnvelope(statementJson: string, signature: bytes, keyId: string): string { + envelope = { + "payloadType": "application/vnd.in-toto+json", + "payload": base64_encode(statementJson), + "signatures": [ + { + "sig": base64_encode(signature), + "keyid": keyId + } + ] + } + return JSON.stringify(envelope, no_whitespace) +} + +function envelopeBytes(envelopeJson: string): int { + return length(utf8_encode(envelopeJson)) +} +``` + +**Rule:** if `envelopeBytes(envelopeJson) > REKOR_MAX_ENTRY_BYTES * REKOR_SIZE_SAFETY_MARGIN`, we consider this envelope **too big** and trigger sharding / externalization logic before calling Rekor. + +> Note: This means you temporarily sign once to measure size. That’s acceptable; signing is cheap compared to a failing Rekor upload. + +### C3 – Guardrail function + +```pseudo +function ensureWithinRekorLimit(envelopeJson: string) { + bytes = envelopeBytes(envelopeJson) + if bytes > REKOR_MAX_ENTRY_BYTES { + throw new OversizeAttestationError(bytes, REKOR_MAX_ENTRY_BYTES) + } +} +``` + +**Definition of done** + +* Utility functions for `jsonBytes`, `buildDsseEnvelope`, `envelopeBytes`, and `ensureWithinRekorLimit`. +* Unit tests: + + * Below limit → pass. + * Exactly at limit → pass. + * Above limit → throws `OversizeAttestationError`. + +--- + +## 6. Sharding / externalization strategy (Ticket group D) + +This is where you decide *what to do* when a statement is too big. + +### D1 – Strategy decision + +Implement in this order: + +1. **Externalize big blobs** (preferred). +2. If still too big, **shard** into multiple attestations. + +#### 1) Externalization rules + +Examples: + +* SBOM: + + * Write full SBOM to artifact store or object storage (S3, GCS, internal). + * In attestation, keep only: + + * URI + * hash + * size + * format +* Test logs: + + * Keep only summary + URI to full logs. + +Implement a helper: + +```pseudo +function externalizeIfLarge(fieldName, dataBytes, thresholdBytes): RefOrInline { + if length(dataBytes) <= thresholdBytes { + return { "inline": true, "value": dataBytes } + } else { + uri = uploadToArtifactStore(dataBytes) + digest = sha256(dataBytes) + return { + "inline": false, + "uri": uri, + "digest": "sha256:" + digest + } + } +} +``` + +#### 2) Sharding rules + +Example for SBOM‑like data: if you have a big `components` list: + +```pseudo +MAX_COMPONENTS_PER_ATTESTATION = 1000 # tune this via tests + +function shardComponents(components[]): + chunks = chunk(components, MAX_COMPONENTS_PER_ATTESTATION) + attestations = [] + for each chunk in chunks: + att = baseStatement() + att["components"] = chunk + attestations.append(att) + return attestations +``` + +After sharding: + +* Each chunk becomes its **own statement** (and its own DSSE envelope + Rekor entry). +* Each statement should include: + + * The same **subject (artifact digest)**. + * A `shardId` and `shardCount`, or a `groupId` (e.g., build ID) to relate them. + +Example: + +```json +{ + "_sharding": { + "groupId": "build-1234-sbom", + "shardIndex": 0, + "shardCount": 3 + } +} +``` + +**D2 – Integration with size guardrail** + +Flow: + +1. Build full statement. +2. If `jsonBytes(statement) <= ATTESTATION_JSON_SOFT_MAX`: use as‑is. +3. Else: + + * Try externalizing big fields. + * Re‑measure JSON size. +4. If still above `ATTESTATION_JSON_SOFT_MAX`: + + * Apply sharding (e.g., split `components` list). +5. For each shard: + + * Build DSSE envelope. + * Run `ensureWithinRekorLimit`. + +If after sharding a single shard **still** exceeds Rekor’s limit, you must: + +* Fail the pipeline with a **clear error**. +* Log enough diagnostics to adjust your thresholds or schemas. + +**Definition of done** + +* Implementation for: + + * `externalizeIfLarge`, + * `shardComponents` (or equivalent for your large arrays), + * `_sharding` metadata. +* Tests: + + * Large SBOM → multiple attestations, each under size limit. + * Externalization correctly moves large fields out and keeps digests. + +--- + +## 7. Rekor client wrapper (Ticket group E) + +### E1 – Wrap Rekor interactions + +Create a small abstraction: + +```pseudo +class RekorClient { + function uploadDsseEnvelope(envelopeJson: string): LogEntryRef { + ensureWithinRekorLimit(envelopeJson) + response = http.post(REKOR_URL + "/api/v1/log/entries", body=envelopeJson) + + if response.statusCode == 201 or response.statusCode == 200: + return parseLogEntryRef(response.body) + else if response.statusCode == 413 or isSizeError(response.body): + throw new RekorSizeLimitError(response.statusCode, response.body) + else: + throw new RekorUploadError(response.statusCode, response.body) + } +} +``` + +* The `ensureWithinRekorLimit` call should prevent most 413s. +* `isSizeError` should inspect message strings that mention “size”, “100KB”, etc., just in case Rekor’s error handling changes. + +### E2 – Error handling strategy + +On `RekorSizeLimitError`: + +* Mark the build as **failed** (or at least **non‑compliant**). + +* Emit a structured log event: + + ```json + { + "event": "rekor_upload_oversize", + "envelopeBytes": 123456, + "rekorMaxBytes": 100000, + "buildId": "build-1234" + } + ``` + +* (Optional) Attach the JSON size breakdown for debugging. + +**Definition of done** + +* Wrapper around existing Rekor client (or direct HTTP). +* Tests for: + + * Successful upload. + * Simulated 413 / size error → recognized and surfaced cleanly. + +--- + +## 8.
