+# Excititor Mirror Connector Charter
+
+## Mission
+Ingest StellaOps VEX mirror bundles into Excititor, converting them into immutable VEX observations without applying consensus or suppression. The connector must honour the Aggregation-Only Contract, maintain provenance, and support offline replay and incremental updates.
+
+## Scope
+- Code in `StellaOps.Excititor.Connectors.StellaOpsMirror`.
+- Bundle validation (signatures, manifests, Merkle roots) and cursor management.
+- Integration with Excititor storage and Surface/VEX Lens consumers.
+- Test fixtures demonstrating deterministic ingest across bundle versions.
+
+## Required Reading
+- `docs/modules/excititor/architecture.md`
+- `docs/modules/concelier/guides/aggregation-only-contract.md`
+- `docs/modules/excititor/mirrors.md` (if available; otherwise coordinate with Docs to add details)
+- `docs/modules/airgap/guides/airgap-mode.md`
+- `docs/modules/concelier/operations/mirror.md` (shared mirror concepts)
+
+## Working Agreement
+1. **Status updates**: set tasks to `DOING`/`DONE` in both sprint file `/docs/implplan/SPRINT_*.md` and local `TASKS.md` when work starts/finishes.
+2. **Provenance preservation**: record bundle IDs, digests, and time anchors in stored observations; avoid derived fields.
+3. **Deterministic replay**: ensure repeated imports of the same bundle produce identical documents; handle supersedes and delta bundles gracefully.
+4. **Offline readiness**: no external network calls; provide clear errors for invalid or stale bundles.
+5. **Testing**: maintain mirror fixtures covering full/delta bundles, supersedes chains, and failure cases.
+6. **Documentation**: coordinate updates to mirror connector docs and release notes when behaviour or configuration changes.

+| EXCITITOR-CONN-STELLA-07-001 | DONE (2025-10-21) | Excititor Connectors – Stella | EXCITITOR-EXPORT-01-007 | **DONE (2025-10-21)** – Implemented `StellaOpsMirrorConnector` with `MirrorManifestClient` + `MirrorSignatureVerifier`, digest validation, signature enforcement, raw document + DTO persistence, and resume cursor updates. Added fixture-backed tests covering happy path and tampered manifest rejection. | Fetch job downloads mirror manifest, verifies DSSE/signature, stores raw documents + provenance; unit tests cover happy path and tampered manifest failure. |
