## Current State Summary

OBPI-0.11.0-03 is complete through the heavy-lane attestation boundary. The
brief is marked `Completed`, the parent ADR checklist now shows OBPI-01 through
OBPI-03 checked, and a completed `obpi_receipt_emitted` event was appended to
`.gzkit/ledger.jsonl` through `uv run gz obpi emit-receipt`. Post-attestation
runtime verification passed: `uv run gz obpi reconcile
OBPI-0.11.0-03-obpi-completion-recorder-and-anchor-receipts --json` now reports
`passed = true` and `runtime_state = attested_completed`, and `uv run gz adr
status ADR-0.11.0-airlineops-obpi-completion-pipeline-parity --json` now
reports `obpi_summary.completed = 3`.

## Important Context

This tranche hardened receipt semantics rather than adding a new workflow.
Completed receipts now preserve `scope_audit`, `git_sync_state`,
`recorder_source`, and `recorder_warnings`, and the hook path snapshots changed
files before the recorder writes `.gzkit/ledger.jsonl` so the receipt does not
self-contaminate its own scope evidence. Manual `gz obpi emit-receipt --event
completed` now enriches the same structured context as the hook path. Best-effort
anchor capture remains non-blocking: degraded git/anchor capture records
warnings instead of rolling back completion.

## Decisions Made

- **Decision:** Keep the completed-receipt anchor at the existing top-level
  `anchor` field.
  **Rationale:** The current ledger/runtime contract already consumes top-level
  anchors; moving it into `evidence` here would create unnecessary drift ahead
  of OBPI-04.
  **Alternatives rejected:** Relocating anchor state into a new nested evidence
  envelope.

- **Decision:** Snapshot `scope_audit` before the recorder appends
  `artifact_edited` / `obpi_receipt_emitted`.
  **Rationale:** Capturing changed files after the ledger write incorrectly
  pulled `.gzkit/ledger.jsonl` into the OBPI transaction scope.
  **Alternatives rejected:** Filtering `.gzkit/ledger.jsonl` after the fact.

- **Decision:** Treat degraded anchor capture and post-completion receipt-write
  failures as explicit warnings, not blockers.
  **Rationale:** AirlineOps parity requires completion decisions to remain
  intact once the fail-closed validator has already allowed the transition.
  **Alternatives rejected:** Reverting brief completion state on recorder
  failure.

## Immediate Next Steps

1. Implement OBPI-0.11.0-04 through `gz-obpi-pipeline`, consuming the new
   `scope_audit`, `git_sync_state`, and anchor evidence for drift detection.
2. Ensure `gz obpi reconcile` and focused ADR status explain per-OBPI drift
   using the structured completion receipts from OBPI-03.
3. After OBPI-04 lands, continue with OBPI-05 and OBPI-06 to finish the parent
   ADR closeout package.

## Pending Work / Open Loops

ADR-0.11.0 remains incomplete with three OBPIs still open: OBPI-04, OBPI-05,
and OBPI-06. The parent ADR remains `Pending` / `pre_closeout` and
`closeout_ready = false` until those OBPIs gain both brief completion and
ledger proof. No dedicated `gz-obpi-audit` or `gz-obpi-sync` CLI surface was
used in this repo; the sync stage was completed through the supported brief
update, `gz obpi emit-receipt`, and ADR checklist reconciliation path.

## Verification Checklist

- [x] `uv run gz validate --documents` passes
- [x] `uv run gz lint` passes
- [x] `uv run gz typecheck` passes
- [x] `uv run gz test` passes
- [x] `uv run mkdocs build --strict` passes
- [x] `uv run -m behave features/` passes
- [x] `uv run gz obpi reconcile OBPI-0.11.0-03-obpi-completion-recorder-and-anchor-receipts --json` reports `passed = true`
- [x] `uv run gz adr status ADR-0.11.0-airlineops-obpi-completion-pipeline-parity --json` reports `obpi_summary.completed = 3`
