# SPRINT_3500_0011_0001 - Build-ID Mapping Index
|
# Sprint 3500.0011.0001 · Build-ID Mapping Index
|
||||||
|
|
||||||
**Priority:** P0 - CRITICAL
|
## Topic & Scope
|
||||||
**Module:** Scanner
|
- Provide an offline-capable index mapping native Build-IDs (ELF GNU build-id, PE CodeView GUID+Age, Mach-O UUID) to PURLs for binary identification in distroless/scratch images.
|
||||||
**Working Directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Native/Index/`
|
- Implement deterministic NDJSON loading + batch lookup, plus DSSE signature verification bound to an index SHA-256 digest.
|
||||||
**Parent Advisory:** `18-Dec-2025 - Building Better Binary Mapping and Call‑Stack Reachability.md`
|
- Working directory: `src/Scanner/StellaOps.Scanner.Analyzers.Native/Index/`.
|
||||||
**Dependencies:** SPRINT_3500_0010_0001 (PE), SPRINT_3500_0010_0002 (Mach-O)
|
- Evidence: tests in `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Native.Tests/Index/OfflineBuildIdIndexTests.cs` and `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Native.Tests/Index/OfflineBuildIdIndexSignatureTests.cs`.
|
||||||
|
|
||||||
---
|
## Dependencies & Concurrency
|
||||||
|
- Depends on: `docs/implplan/SPRINT_3500_0010_0001_pe_full_parser.md` and `docs/implplan/SPRINT_3500_0010_0002_macho_full_parser.md` (full Build-ID extraction coverage).
|
||||||
|
- Safe to execute in parallel with Emit/Worker integration sprints; this sprint is scoped to the index library surface and test coverage.
|
||||||
|
|
||||||
## Objective
|
## Documentation Prerequisites
|
||||||
|
- `docs/modules/scanner/architecture.md`
|
||||||
Implement an offline-capable index that maps Build-IDs (ELF GNU build-id, PE CodeView GUID+Age, Mach-O UUID) to Package URLs (PURLs), enabling binary identification in distroless/scratch images.
|
- Parent advisory: `docs/product-advisories/18-Dec-2025 - Building Better Binary Mapping and Call-Stack Reachability.md`

|
## Decisions & Risks
|
||||||
|
### Decisions
|
||||||
|
- Require `outcome.IsValid` and `outcome.IsTrusted` for Build-ID index DSSE verification; bind the index content by verifying the payload SHA-256 matches the computed index SHA-256.
|
||||||
|
|
||||||
|
### Risks
|
||||||
|
| Risk | Mitigation |
|
||||||
|
| --- | --- |
|
||||||
|
| Hosts must configure ProofSpine DSSE trust to load a signed index when `RequireSignature=true`. | Document required configuration in host runbooks; ensure hosts register `IDsseSigningService` and bind index path/signature settings. |

# SPRINT_3500_0012_0001 - Binary SBOM Component Emission
|
# Sprint 3500.0012.0001 · Binary SBOM Component Emission
|
||||||
|
|
||||||
**Priority:** P0 - CRITICAL
|
## Topic & Scope
|
||||||
**Module:** Scanner
|
- Emit native binaries as CycloneDX/SPDX file-level components with build identifiers.
|
||||||
**Working Directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Emit/Native/`
|
- Resolve PURLs via Build-ID index when available; fall back to deterministic `pkg:generic` with build-id qualifiers.
|
||||||
**Parent Advisory:** `18-Dec-2025 - Building Better Binary Mapping and Call‑Stack Reachability.md`
|
- Working directory: `src/Scanner/__Libraries/StellaOps.Scanner.Emit/Native/`.
|
||||||
**Dependencies:** SPRINT_3500_0011_0001 (Build-ID Index)
|
|
||||||
|
|
||||||
---
|
## Dependencies & Concurrency
|
||||||
|
- Depends on: `docs/implplan/SPRINT_3500_0011_0001_buildid_mapping_index.md` (Build-ID index contract and lookup semantics).
|
||||||
|
- Safe to execute in parallel with other Scanner modules; this sprint is scoped to SBOM emission.
|
||||||
|
|
||||||
## Objective
|
## Documentation Prerequisites
|
||||||
|
- `docs/modules/scanner/architecture.md`
|
||||||
|
- Parent advisory: `18-Dec-2025 - Building Better Binary Mapping and Call‑Stack Reachability.md`
|
||||||
|
|
||||||
Emit native binaries as CycloneDX/SPDX file-level components with build identifiers, linking to the Build-ID index for PURL resolution.

## Decisions & Risks
|

|
### Decisions
|

|
- Use sorted/normalized property emission for deterministic CycloneDX output.

|
### Risks
|

|
| Risk | Mitigation |

|

|
||||||
|
| Build-ID index confidence/metadata drift may affect PURL resolution stability. | Keep confidence and source distro recorded as component properties; ensure deterministic fallback to `pkg:generic` when unresolved. |

## Acceptance Criteria

### Acceptance Criteria

|
- [x] Exclusion patterns respected

||||||
|
- [x] Deterministic synthetic layer digest used for native file components
|
||||||
|
|
||||||
|
## Interlocks
|
||||||
|
- Native component emission must remain compatible with `LayerComponentFragment` merge semantics and CycloneDX composition in `StellaOps.Scanner.Emit`.

|

|
||||||
|
## Decisions & Risks
|
||||||
|
### Decisions
|
||||||
|
- Use a deterministic synthetic layer digest for native analysis output (`sha256( "stellaops:native" )`) to keep SBOM fragments stable and layer-aware.
|
||||||
|
|
||||||
|
### Risks
|
||||||
|
| Risk | Mitigation |
|
||||||
|
| --- | --- |
|
||||||
|
| Native discovery/emission is rooted in filesystem enumeration; deeper binary dependency edges and Build-ID extraction improvements are tracked by native analyzer sprints. | Keep this sprint scoped to dispatcher integration; feed improvements through `StellaOps.Scanner.Analyzers.Native` and Build-ID index integration work. |

# SPRINT_3620_0002_0001 - Path Explanation Service
|
# Sprint 3620.0002.0001 · Path Explanation Service
|
||||||
|
|
||||||
**Priority:** P1 - HIGH
|
## Topic & Scope
|
||||||
**Module:** Scanner
|
- Provide deterministic reconstruction + rendering of reachability paths (entrypoint → sink) with gate annotations for UI/CLI consumption.
|
||||||
**Working Directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/Explanation/`
|
- Owning directory: `src/Scanner/__Libraries/StellaOps.Scanner.Reachability/Explanation/`.
|
||||||
**Parent Advisory:** `18-Dec-2025 - Building Better Binary Mapping and Call‑Stack Reachability.md`
|
- Evidence: unit tests in `src/Scanner/__Tests/StellaOps.Scanner.Reachability.Tests/PathExplanationServiceTests.cs` and CLI wiring for `stella graph explain` (`src/Cli/StellaOps.Cli/Commands/CommandFactory.cs`).
|
||||||
**Dependencies:** Any call graph extractor
|
|
||||||
|
|
||||||
---
|
## Dependencies & Concurrency
|
||||||
|
- Depends on: RichGraph generation + gate tagging (`StellaOps.Scanner.Reachability.Gates`).
|
||||||
|
- Cross-module: `stella graph explain` lives in the CLI module (tracked in `docs/implplan/SPRINT_3620_0003_0001_cli_graph_verify.md`); this sprint’s code scope remains the Scanner reachability explanation library.
|
||||||
|
- No DB/schema work; safe to execute in parallel with other reachability work.
|
||||||
|
|
||||||
## Objective
|
## Documentation Prerequisites
|
||||||
|
- `docs/modules/scanner/architecture.md`
|
||||||
|
- `docs/reachability/hybrid-attestation.md`
|
||||||
|
- Parent advisory: `18-Dec-2025 - Building Better Binary Mapping and Call‑Stack Reachability.md`
|
||||||
|
|
||||||
Provide user-friendly rendering of reachability paths for UI/CLI display, showing how entrypoints reach vulnerable sinks with gate information.

## Acceptance Criteria
|
### Test Evidence
|
||||||
|
- `src/Policy/__Tests/StellaOps.Policy.Engine.Tests/Attestation/PolicyDecisionAttestationServiceTests.cs` (covers signer + optional Rekor paths via mocks)
|
||||||
|
|
||||||
- [ ] `stella.ops/policy-decision@v1` predicate type added to constants
|
### Acceptance Criteria
|
||||||
- [ ] Predicate includes `inputs` with SBOM, VEX, Graph attestation references
|
- [x] `stella.ops/policy-decision@v1` predicate type added to constants
|
||||||
- [ ] Signing follows existing DSSE/in-toto patterns

|
- [x] Signing follows existing DSSE/in-toto patterns
|

|
## Interlocks
|
||||||
|
- Predicate type constant must remain aligned across Signer + Policy Engine.

|
- None scheduled.
