# Evidence

Branch: `DBR-001`

## Observed Before Implementation

- `docs/doc-branches/` contained no existing `DBR-*` instance on commit
  `a872051`.
- `AGENTS.md` required a single writer for `.prd_plugin/state/*` and
  `.prd_plugin/ids/registry.json`.
- `mcp/server.cjs` placed its coordination lock under the checkout-local
  `.prd_plugin/local/` directory.
- `ARCH-RISK-004` described concurrent agent/subagent writers but mitigated the
  risk only with the same-process/worktree lock plus the single-writer rule.

## Focused Proof

`EV-059` records the first promotion proof:

- `node --test tests/node/server.test.cjs`: 44/44 passed, including two isolated
  worktree copies, distinct promotion IDs, idempotent retry, assigned-owner
  enforcement, additive merge, and conflicting summary rejection.
- `python -m unittest tests.test_state_consistency_check tests.test_prd_graph -v`:
  28/28 passed, including branch/canonical consistency and graph provenance.
- `python -m unittest tests.test_config_toggles -v`: 20/20 passed, including
  branch-policy defaults across every config template.

## Repository-wide Proof

`EV-060` records the implementation review and pre-release proof:

- `python scripts/local_workflow_check.py`: completed, including all 691 tests,
  structured-file validation, gap audit, release hygiene, doctor, state
  consistency, skill installation dry-run, request report, and message check.
- State consistency, self-audit, staleness, wiki drift, ingest-manual drift,
  fork drift, gap audit, and release hygiene produced no change-specific
  findings.
- Narrative `DBR-*` manifests now participate in the traceability graph; the
  new document branch has no dangling graph identity.
- `npm pack --dry-run --json`: `prd-plugin@0.9.2`, 438 entries, 757,904 bytes,
  and zero `__pycache__`/`.pyc` artifacts.
- `HLT-008` is resolved and `DEC-004` records the settled worker/lead boundary.

At the `EV-060` checkpoint, remote merge, tag-triggered publication, and npm
registry visibility remained under `TRK-082`; the proof below completes them.

## Release Proof

`EV-061` closes the publication requirement:

- `main` and annotated tag `v0.9.2` point at released commit `feffaac`.
- GitHub Actions **Publish to npm** run
  `https://github.com/markusuk1/prd-plugin/actions/runs/29242622943`
  completed successfully for `v0.9.2`.
- `npm view prd-plugin@0.9.2 version dist.shasum time.0.9.2 --json`
  returned version `0.9.2` and shasum
  `b8832dc5dde97ed4b071e252d2ac82e72248e35e`.

The branch is promoted with no unresolved change-specific limitation.
