## Dependencies & Concurrency
- Sprint 0338 (monotonicity + quarantine) must be complete.
- `StellaOps.AirGap.Importer` provides verification primitives (DSSE/TUF/Merkle + monotonicity/quarantine hooks).
- CLI command routing uses `System.CommandLine` (keep handlers composable + testable).
- Concurrency: avoid conflicting edits in `src/Cli/StellaOps.Cli/Commands/CommandFactory.cs` while other CLI sprint work is in-flight.
## Documentation Prerequisites
- `docs/modules/cli/architecture.md`
- `docs/modules/platform/architecture-overview.md`
- `docs/product-advisories/14-Dec-2025 - Offline and Air-Gap Technical Reference.md`

## Interlocks
- Changes touch `src/Cli/StellaOps.Cli/Commands/CommandFactory.cs`; avoid concurrent command-group rewires.
- `verify offline` may require additional policy/verification contracts; if missing, mark tasks BLOCKED with concrete dependency and continue.
## Upcoming Checkpoints

- Add man-page style help text for each command
## Decisions & Risks
- 2025-12-15: Normalised sprint file to standard template; started T1 (structure design) and moved the remaining tasks unchanged.
- 2025-12-15: Implemented `offline import/status` + exit codes; added tests/docs; marked T5/T9/T10 BLOCKED due to missing verifier/policy contracts.

| Offline Rekor verification contract missing/incomplete | Cannot meet `--verify-rekor` acceptance criteria. | Define/land offline inclusion proof verification contract/library and wire into CLI. | DevEx/CLI | Blocked |
| `.tar.zst` payload inspection not implemented | Limited local validation (hash/sidecar checks only). | Add deterministic Zstd+tar inspection path (or reuse existing bundle tooling) and cover with tests. | DevEx/CLI | Open |
| `verify offline` policy schema unclear | Risk of implementing an incompatible policy loader/verifier. | Define policy schema + canonicalization/evaluation rules; then implement `verify offline` and `--policy`. | DevEx/CLI | Blocked |

- `T7/T8` blocked: Scanner has no OfflineKit import pipeline consuming DSSE verification yet (owning module + API/service design needed).

**Gaps Addressed:** G11 (Prometheus Metrics), G12 (Structured Logging), G13 (Error Codes), G14 (Audit Schema)
## Dependencies & Concurrency
- Depends on Sprint 0338 (Monotonicity, Quarantine) for importer integration points and event fields.
- Depends on Sprint 0339 (CLI) for exit code mapping.
- Prometheus/OpenTelemetry stack must be available in-host; exporter choice must match existing service patterns.
- Concurrency note: touches AirGap Importer + CLI + Authority storage; avoid cross-module contract changes without recording them in this sprints Decisions & Risks.
---
## Objective
Implement comprehensive observability for offline kit operations: Prometheus metrics per advisory §10, standardized structured logging fields per §10.2, machine-readable error codes per §11.2, and enhanced audit schema per §13.2. This enables operators to monitor, debug, and audit air-gap operations effectively.

| 2025-12-15 | Normalised sprint file to standard template; set `T1` to `DOING` and began implementation. | Agent |
| 2025-12-15 | Implemented Offline Kit metrics + structured logging primitives in AirGap Importer; marked `T7` `BLOCKED` pending an owning host/service for a `/metrics` surface. | Agent |
| 2025-12-15 | Started CLI error/reason code work; expanded sprint working directories for CLI parsing (`Output/`, `Services/`, `Services/Transport/`). | Agent |
| 2025-12-15 | Added Authority Postgres migration + repository/emitter for `authority.offline_kit_audit`; marked `T20` `BLOCKED` pending an owning backend import/activation flow. | Agent |
| 2025-12-15 | Completed `T1`-`T6`, `T8`-`T19`, `T21`-`T24` (metrics/logging/codes/audit, tests, docs, dashboard); left `T7`/`T20` `BLOCKED` pending an owning Offline Kit import host. | Agent |
| 2025-12-15 | Cross-cutting Postgres RLS compatibility: set both `app.tenant_id` and `app.current_tenant` on tenant-scoped connections (shared `StellaOps.Infrastructure.Postgres`). | Agent |
## Decisions & Risks
- **Prometheus exporter choice (Importer):** `T7` is `BLOCKED` because the repo currently has no backend Offline Kit import host (no `src/**` implementation for `POST /api/offline-kit/import`), so there is no clear owning service to expose `/metrics`.
- **Field naming:** Keep metric labels and log fields stable and consistent (`tenant_id`, `status`, `reason_code`) to preserve dashboards and alert rules.
- **Authority schema alignment:** `docs/db/SPECIFICATION.md` must stay aligned with `authority.offline_kit_audit` (table + indexes + RLS posture) to avoid drift.
- **Integration test dependency:** Authority Postgres integration tests use Testcontainers and require Docker in developer/CI environments.
- **Audit wiring:** `T20` is `BLOCKED` until an owning backend Offline Kit import/activation flow exists to call the audit emitter/repository.
## Next Checkpoints
- After `T7`: verify the owning services `/metrics` endpoint exposes Offline Kit metrics + labels and the Grafana dashboard queries work.
- After `T20`: wire the audit emitter into the import/activation flow and verify tenant-scoped audit rows are written.

## Objective
## Topic & Scope
- Implement the 5-step deterministic evidence reconciliation algorithm per advisory §5 so offline environments can construct a consistent, reproducible evidence graph from SBOMs, attestations, and VEX documents.
- Evidence: deterministic artifact indexing + normalization, precedence lattice merge, deterministic `evidence-graph.json` + `evidence-graph.sha256`, optional DSSE signature, and determinism tests/fixtures.
- **Working directory:** `src/AirGap/StellaOps.AirGap.Importer/` (new `Reconciliation/` components).
Implement the 5-step deterministic evidence reconciliation algorithm as specified in advisory §5. This enables offline environments to construct a consistent, reproducible evidence graph from SBOMs, attestations, and VEX documents using lattice-based precedence rules.
## Dependencies & Concurrency
- Depends on Sprint 0338 (`DsseVerifier` and importer verification primitives).
- Depends on Sprint 0339 (CLI `verify offline`) for eventual wiring.
- Depends on Rekor inclusion proof verification contract/library work (see `docs/implplan/SPRINT_3000_0001_0001_rekor_merkle_proof_verification.md`) before `T8` can be implemented.
- Concurrency note: this sprint introduces new reconciliation contracts; avoid cross-module coupling until the graph schema is agreed and documented.

## Decisions & Risks
- **Rekor offline verifier dependency:** `T8` depends on an offline Rekor inclusion proof verifier contract/library (see `docs/implplan/SPRINT_3000_0001_0001_rekor_merkle_proof_verification.md`).
- **SBOM/VEX parsing contracts:** `T5`/`T6`/`T13` require stable parsers and canonicalization rules (SPDX/CycloneDX/OpenVEX) before golden fixtures can be committed without churn.
- **Determinism risk:** normalization and lattice merge must guarantee stable ordering and stable hashes across platforms; budget time for golden-file + cross-platform CI validation.
## Interlocks
- `T8` blocks full offline attestation verification until Rekor inclusion proof verification is implemented and its inputs/outputs are frozen.
- `T23` blocks CLI wiring until Sprint 0339 unblocks `verify offline` (policy schema + evaluation semantics).
## Action Tracker

- Before `T8`: confirm Rekor inclusion proof verification contract and offline mirror format.

When `AirGapped.UsePostgresOnly` is true:
1. Skip Valkey cache, use Postgres-backed cache
2. Use PostgreSQL `NOTIFY/LISTEN` for SSE updates instead of message bus
3. Store snapshots only in `first_signal_snapshots` table
Air-gap-friendly profile (recommended defaults):
1. Use `FirstSignal:Cache:Backend=postgres` and configure `messaging:postgres` for PostgreSQL-only operation.
2. Keep SSE `first_signal` updates via polling (no `NOTIFY/LISTEN` implemented in this sprint).
3. Optionally enable `FirstSignal:SnapshotWriter` to proactively warm snapshots/caches for a single configured tenant.
