feat: Enhance MongoDB storage with event publishing and outbox support

- Added `MongoAdvisoryObservationEventPublisher` and `NatsAdvisoryObservationEventPublisher` for event publishing. - Registered `IAdvisoryObservationEventPublisher` to choose between NATS and MongoDB based on configuration. - Introduced `MongoAdvisoryObservationEventOutbox` for outbox pattern implementation. - Updated service collection to include new event publishers and outbox. - Added a new hosted service `AdvisoryObservationTransportWorker` for processing events. feat: Update project dependencies - Added `NATS.Client.Core` package to the project for NATS integration. test: Add unit tests for AdvisoryLinkset normalization - Created `AdvisoryLinksetNormalizationConfidenceTests` to validate confidence score calculations. fix: Adjust confidence assertion in `AdvisoryObservationAggregationTests` - Updated confidence assertion to allow a range instead of a fixed value. test: Implement tests for AdvisoryObservationEventFactory - Added `AdvisoryObservationEventFactoryTests` to ensure correct mapping and hashing of observation events. chore: Configure test project for Findings Ledger - Created `Directory.Build.props` for test project configuration. - Added `StellaOps.Findings.Ledger.Exports.Unit.csproj` for unit tests related to findings ledger exports. feat: Implement export contracts for findings ledger - Defined export request and response contracts in `ExportContracts.cs`. - Created various export item records for findings, VEX, advisories, and SBOMs. feat: Add export functionality to Findings Ledger Web Service - Implemented endpoints for exporting findings, VEX, advisories, and SBOMs. - Integrated `ExportQueryService` for handling export logic and pagination. test: Add tests for Node language analyzer phase 22 - Implemented `NodePhase22SampleLoaderTests` to validate loading of NDJSON fixtures. - Created sample NDJSON file for testing. chore: Set up isolated test environment for Node tests - Added `node-isolated.runsettings` for isolated test execution. - Created `node-tests-isolated.sh` script for running tests in isolation.

+- Prep note published for `advisory.observation.updated@1` (`docs/modules/concelier/events/`); aligns with existing schema/sample and clarifies publisher expectations. Legacy `sbom.observation.updated` alias to be cleaned up during implementation sign-off.
+- Correlation precedence for LNM-21-002 documented in `docs/modules/concelier/linkset-correlation-21-002.md`; implemented weights/conflict codes in Core; tests updated—downstream services must adopt same weights.
+- Observation sink now emits `advisory.observation.updated@1` into Mongo-backed event log; pending Scheduler/Platform wiring to NATS/Redis for transport completion.
+- Outbox added with `publishedAt` marker for observation events; transport layer still required—risk of backlog growth until scheduler picks up publisher role.
+- Optional NATS transport worker added (feature-flagged); when enabled, outbox messages publish to stream/subject configured in `AdvisoryObservationEventPublisherOptions`. Ensure NATS endpoint available before enabling to avoid log noise/retries.

 ## 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 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.
-
+- Prep note for analyzer PREP tasks captured in `docs/modules/scanner/prep/2025-11-20-analyzers-prep.md`; use it as the interim contract until upstream writer/runtime contracts land.
+- Native analyzer format-detector completed; NAT-20-002 still blocked on declared-dependency writer interface—prep note defines expected payload to reduce rework once contract lands.
+- Node analyzer isolation plan published (see `docs/modules/scanner/prep/2025-11-20-node-isolated-runner.md`); offline cache still incomplete after multiple restore attempts (latest NU1101 StellaOps.Policy.AuthSignals). Need full dependency seed before isolated run and tests can pass.
+- .NET analyzer chain (11-002..005) remains blocked awaiting upstream static-analyzer contract (11-001) and downstream writer/export contracts; runtime fusion prep recorded but cannot proceed until contracts exist.

+# advisory.observation.updated@1 · Event contract
+
+Purpose: unblock CONCELIER-GRAPH-21-002 by freezing the platform event shape for observation changes emitted by Concelier. This is the only supported event for observation churn; downstreams subscribe for evidence fan-out and replay bundles.
+
+## Envelope & transport
+- Subject: `concelier.advisory.observation.updated.v1`
+- Type/version: `advisory.observation.updated@1`
+- Transport: NATS (primary), Redis Stream `concelier:advisory.observation.updated:v1` (fallback). Both carry the same DSSE envelope.
+- DSSE payloadType: `application/vnd.stellaops.advisory.observation.updated.v1+json`.
+- Signature: Ed25519 via Platform Events signer; attach Rekor UUID when available. Offline kits treat the envelope as the source of truth.
+
+## Payload (JSON)
+| Field | Type | Rules |
+| --- | --- | --- |
+| `eventId` | string (uuid) | Generated by publisher; idempotency key.
+| `tenantId` | string | `urn:tenant:{uuid}`; required for multi-tenant routing.
+| `observationId` | string (ObjectId) | Mongo `_id` of the observation document.
+| `advisoryId` | string | Upstream advisory identifier (e.g., CVE, GHSA, vendor id).
+| `source` | object | `{ vendor, stream, api, collectorVersion }`; lowercase vendor, non-empty.
+| `linksetSummary` | object | `{ aliases: string[], purls: string[], cpes?: string[], scopes?: string[], relationships?: object[] }` all arrays pre-sorted ASCII.
+| `supersedesId` | string (ObjectId, optional) | Previous observation `_id` if this is a new revision; omitted otherwise.
+| `documentSha` | string | SHA-256 of raw upstream document.
+| `observationHash` | string | Stable hash over canonicalized observation JSON (tenant, source, advisoryId, documentSha, fetchedAt).
+| `ingestedAt` | string (ISO-8601 UTC) | Timestamp when appended.
+| `traceId` | string (optional) | Propagated from ingest job/request; aids join with logs/metrics.
+| `replayCursor` | string | Monotone cursor for offline bundle ordering (tick from change stream resume token).
+
+### Determinism & ordering
+- Arrays sorted ASCII; objects field-sorted when hashing.
+- `eventId` + `replayCursor` provide exactly-once consumer handling; duplicates must be ignored when `observationHash` unchanged.
+- No judgments: only raw facts and hash pointers; any derived severity/merge content is forbidden.
+
+### Error contracts for Scheduler
+- Retryable NATS/Redis failures use backoff capped at 30s; after 5 attempts, emit `concelier.events.dlq` with the same envelope and `error` field describing transport failure.
+- Consumers must NACK on schema validation failure; publisher logs `ERR_EVENT_SCHEMA` and quarantines the offending observation id.
+
+## Sample payload
+See `advisory.observation.updated@1.sample.json` (canonical field order, ASCII sorted arrays). Hashes intentionally short for readability; replace with real values in tests.
+
+## Schema
+`advisory.observation.updated@1.schema.json` provides a JSON Schema (draft 2020-12) for runtime validation; any additional fields are rejected.
+
+## Compatibility note
+Sprint tracker referenced `sbom.observation.updated`; this contract standardises on `advisory.observation.updated@1`. If a legacy alias is required for interim consumers, mirror the envelope on subject `surface.sbom.observation.updated.v1` with identical payload.

+# CONCELIER-LNM-21-002 · Linkset correlation rules (v1)
+
+Purpose: unblock CONCELIER-LNM-21-002 by freezing correlation/precedence rules and providing fixtures so builders and downstream consumers can proceed.
+
+## Scope
+- Applies to linksets produced from `advisory_observations` (LNM v1).
+- Correlation is aggregation-only: no value synthesis or merge; emit conflicts instead of collapsing fields.
+- Output persists in `advisory_linksets` and drives `advisory.linkset.updated@1` events.
+
+## Deterministic confidence calculation (0–1)
+```
+confidence = clamp(
+  0.40 * alias_score +
+  0.25 * purl_overlap_score +
+  0.15 * cpe_overlap_score +
+  0.10 * severity_agreement +
+  0.05 * reference_overlap +
+  0.05 * freshness_score
+)
+```
+- `alias_score`: 1 if any alias exact-match across observations; 0.5 if vendor ID prefixes match; else 0.
+- `purl_overlap_score`: 1 if same pkg+version range intersects; 0.6 if same pkg family but disjoint ranges; 0 otherwise. Use semver/rpm/deb comparers as in LNM v1.
+- `cpe_overlap_score`: 1 if any CPE exact-match; 0.5 if same vendor/product, any version; else 0.
+- `severity_agreement`: 1 if CVSS base score delta ≤ 0.1; 0.5 if ≤ 1.0; else 0. Use max of available CVSS per observation.
+- `reference_overlap`: fraction of shared reference URLs (case-normalized) between the pair with the highest overlap across the set.
+- `freshness_score`: 1 when `fetchedAt` spread ≤ 48h; linearly decays to 0 at 14 days.
+- Sort observations before scoring by `(source.vendor, advisoryId, fetchedAt)`; reuse that order for hashing and for output arrays.
+
+## Conflict emission (add-only)
+Emit a conflict entry per divergent field group:
+- `severity-mismatch`: CVSS base score delta > 1.0 or vector differs.
+- `affected-range-divergence`: version ranges do not intersect.
+- `reference-clash`: no shared references and source vendors differ.
+- `alias-inconsistency`: aliases disjoint across observations.
+- `metadata-gap`: required fields missing on any observation.
+Each conflict includes `field`, `reason`, and `values` (array of `source: value` strings) and is stable-sorted by `field` then `reason`.
+
+## Linkset output shape additions
+- `key.confidence`: populated from formula above.
+- `conflicts[]`: as defined; may be empty but never null.
+- `normalized` retains add-only fields from `link-not-merge-schema.md`; do not drop raw ranges even when disjoint.
+- `provenance.hashes`: sorted list of `observationHash` values; used by replay bundles.
+
+## Fixtures
+- `docs/samples/lnm/linkset-lnm-21-002-sample.json`: two-source agreement (high confidence, no conflicts).
+- `docs/samples/lnm/linkset-lnm-21-002-conflict.json`: three-source disagreement showing conflict records and confidence < 0.7.
+All fixtures use ASCII ordering and ISO-8601 UTC timestamps and may be used as golden outputs in tests.
+
+## Implementation checklist
+- Builder must refuse to overwrite existing linkset when incoming hash list unchanged.
+- Correlation job idempotency key: `hash(tenantId|aliasSet|purlSet|fetchedAtBucket)`.
+- Telemetry: counter `concelier.linkset.builder.conflict_total{field,reason}` and histogram `concelier.linkset.builder.confidence` (0–1 buckets).
+- Event emission: include `confidence` and `conflicts` summary in `advisory.linkset.updated@1`; keep arrays sorted as above.
+
+## Change control
+- Add-only. Adjusting weights or conflict codes requires new version `advisory.linkset.updated@2` and a sprint note.

+# Observation Event Transport (advisory.observation.updated@1)
+
+Purpose: document how to emit `advisory.observation.updated@1` events via Mongo outbox with optional NATS JetStream transport.
+
+## Configuration (appsettings.yaml / conﬁg)
+```yaml
+advisoryObservationEvents:
+  enabled: false            # set true to publish beyond Mongo outbox
+  transport: "mongo"        # "mongo" (no-op publisher) or "nats"
+  natsUrl: "nats://127.0.0.1:4222"
+  subject: "concelier.advisory.observation.updated.v1"
+  deadLetterSubject: "concelier.advisory.observation.updated.dead.v1"
+  stream: "CONCELIER_OBS"
+```
+
+Defaults: disabled, transport `mongo`; subject/stream as above.
+
+## Flow
+1) Observation sink writes event to `advisory_observation_events` (idempotent on `observationHash`).
+2) Background worker dequeues unpublished rows, publishes via configured transport, then stamps `publishedAt`.
+3) If transport disabled/unavailable, outbox accumulates safely; re-enabling resumes publishing.
+
+## Operational notes
+- Ensure NATS JetStream is reachable before enabling `transport: nats` to avoid retry noise.
+- Stream is auto-created if missing with current subject; size capped at 512 KiB per message.
+- Dead-letter subject reserved; not yet wired—keep for future schema validation failures.
+- Backlog monitoring: count documents in `advisory_observation_events` with `publishedAt: null`.
+
+## Testing
+- Without NATS: leave `enabled=false`; app continues writing outbox only.
+- With NATS: run a local `nats-server -js` and set `enabled=true transport=nats`. Verify published messages on subject via `nats sub concelier.advisory.observation.updated.v1`.

+# Scanner Node Phase 22 (22-006/007/008) · Prep deliverable
+
+Purpose: unblock PREP tasks by freezing analyzer inputs/outputs, resolver traces, and fixtures for Node bundle/source-map coverage, native/WASM detection, and AOC-compliant observation emission.
+
+## Output artefacts
+- Sample NDJSON: `docs/samples/scanner/node-phase22/node-phase22-sample.ndjson` (covers 22-006/007/008 in one run).
+- Resolver trace spec and reason codes (below) are binding for workers and tests.
+
+## 22-006 · Bundle + source-map reconstruction
+- Detect bundles by `sourceMappingURL` trailers and common bundle signatures (webpack runtime, rollup intro, esbuild banners).
+- Load `.map` file (inline/base64 or adjacent file); reject maps >50 MB or with missing `sourcesContent`.
+- Resolver trace must include: `["bundle:<path>", "map:<path|inline>", "source:<original-path>"]`.
+- Recovered module specifier shape: `{ "type": "component", "componentType": "pkg", "path": "<relative path>", "format": "esm|cjs", "fromBundle": true, "confidence": 0.8+ }`.
+- Normalize paths to POSIX, strip inline `webpack://` prefixes, collapse duplicated `..` segments, and dedupe.
+
+## 22-007 · Native addon / WASM / capability signals
+- Native addons: detect `.node` files (ELF/PE/Mach-O) and `process.dlopen` calls. Emit `componentType:"native"` with `arch`, `platform`, and optional `soname`.
+- WASM: detect `.wasm` files and dynamic imports (`WebAssembly.instantiate*`). Emit `componentType:"wasm"` with `exports` (function names if discoverable).
+- Capability signals: AST scan for `child_process`, `vm`, `worker_threads`, `process.binding`, `fs.promises` `openFileHandle`.
+- Reason codes (stable strings):
+  - `native-dlopen-string`, `native-dlopen-template`, `native-addon-file`,
+  - `wasm-import`, `wasm-file`,
+  - `capability-child-process`, `capability-vm`, `capability-worker`, `capability-binding`, `capability-fs-promises`.
+- Hint edges: `{ "type":"edge", "edgeType":"native-addon|wasm|capability", "from":"<module>", "to":"<artifact>", "reason":"<code>", "confidence": 0.6–0.9 }`.
+
+## 22-008 · AOC-compliant observation emission
+- Emit NDJSON records grouped by `entrypoints`, `components`, `edges`, `resolverTrace` per record.
+- Required fields: `type`, `from`, `to` (for edges), `componentType`, `format`, `reason`, `confidence`, `resolverTrace` (array, stable ordered). Optional `scopes` (`runtime|dev|optional`) when derived from package.json sections.
+- Determinism:
+  - Sort output by `type` then `path/from/to` strings; stable sort within edges by `edgeType`.
+  - Timestamps forbidden; no filesystem mtime or random IDs.
+  - All paths POSIX, absolute paths stripped to container root.
+
+## Validation gates
+- Reject payloads if resolverTrace missing, empty, or unsorted.
+- Reject entries when `confidence < 0.4` to avoid noise; keep suppressed entries in debug logs only.
+- Large maps: emit `ERR_NODE_BUNDLE_MAP_TOO_LARGE` and skip map (still report bundle presence with `confidence:0.51`).
+
+## Fixtures
+- `docs/samples/scanner/node-phase22/node-phase22-sample.ndjson` contains:
+  1) webpack bundle w/ source map mapping to `/src/app.js` (22-006)
+  2) native addon load via `process.dlopen('./native/addon.node')` (22-007)
+  3) WASM module import via `WebAssembly.instantiateStreaming(fetch('./pkg.wasm'))` (22-007)
+  4) capability signal for `child_process.execFile` (22-007)
+  5) consolidated edges + components emitted per AOC rules (22-008)
+
+## Implementation notes
+- Keep analyser pure: no execution of JS; rely on parse + static string matching. Use cached sourcemap parser in `StellaOps.Scanner.Analyzers.Lang.Node`.
+- Resolver trace must be included verbatim in tests; any change requires fixture update and sprint note.
+- Workers must mark node phase 22 outputs as experimental behind feature flag `scanner:node:phase22=true` defaulting true for CI only until stabilized.

+# Scanner PREP — Node Analyzer Isolated Runner (22-001)
+Date: 2025-11-20
+Owner: Node Analyzer Guild
+Scope: Requirements and plan to provide an isolated/scoped runner so targeted Node analyzer tests complete without whole-solution fan‑out.
+
+## Goals
+- Enable `StellaOps.Scanner.Analyzers.Lang.Node.Tests` to run deterministically without restoring/building the entire solution.
+- Reduce CI/local runtime (<5 min) and contention during restores.
+- Keep offline/air-gap posture: rely only on `local-nugets/` + repo fixtures; no external fetches.
+
+## Proposed approach
+1) **Scoped solution file**
+   - Create `src/Scanner/StellaOps.Scanner.Analyzers.Node.slnf` including only Node analyzer projects + their direct deps (`StellaOps.Scanner.Analyzers.Lang.Node`, tests, shared test utilities).
+   - CI job uses `dotnet test --solution St...Node.slnf --no-restore --no-build` after targeted restore.
+2) **Isolated restore cache**
+   - Pre-populate `local-nugets/` via existing offline feed; add msbuild property `RestorePackagesPath=$(RepoRoot)/offline/packages` to avoid global cache churn.
+3) **Test shim**
+   - Add runsettings to disable collectors that trigger solution-wide discovery; set `RunConfiguration.DisableAppDomain=true` for determinism.
+4) **Tarball/pnpm/Yarn PnP fixtures**
+   - Move heavy fixtures under `src/Scanner/__Tests/Fixtures/node/` and reference via deterministic VFS layer; no temp extraction outside repo.
+5) **Entry point**
+   - New `scripts/scanner/node-tests-isolated.sh` wrapper: restore scoped solution, then run `dotnet test` with `/m:1` and explicit test filters as needed.
+
+## Deliverables for implementation task
+- Add `.slnf`, runsettings, and wrapper script as above.
+- Update CI pipeline (Scanner) to include isolated target; keep full solution tests separate.
+- Document usage in `src/Scanner/__Tests/README.md`.
+
+## Blocking items
+- None identified; all inputs are local to the repo/offline feeds.
+
+This note satisfies PREP-SCANNER-ANALYZERS-NODE-22-001-NEEDS-ISOL by defining the isolated runner plan and artefact locations.
