📝 Walkthrough

Walkthrough

The review and contribution guidance now uses README.md instead of PRD.md for project scope, supported backends, capability limits, and contribution references.

Changes

Scope guidance

Layer / File(s)	Summary
README scope references .dap/review/engineering.md, CONTRIBUTING.md	Review guidance and contribution instructions now reference README capabilities, supported backends, specification compliance, and out-of-scope content.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: ⚪ Minimal · up to 01e10

This documentation-only change redirects contributors to maintained project guidance and removes a missing PRD.md dependency; it introduces no actionable merge-blocking risk beyond normal checks and review.

Poem

A rabbit reads the README bright

Scope and limits now shine with light
PRD paths hop away
Clear guidance leads the way
Contributions grow right

Code Review — head 01e1094

Reviewed PR #126 at head 01e1094, one commit and two changed documentation/directive files against base 6702fb2. Read the base review directives, the base README and CONTRIBUTING guidance, the full changed files, and the relevant repository references. Verified the replacement links resolve to tracked README/CONTRIBUTING targets and that the updated scope wording matches the README's capability matrix and Out of scope section. No concrete findings. Runtime dimensions (transactions, idempotency, tenancy, event flow, migrations, lifecycle, input handling, backend parity, and runtime correctness) were not implicated by this documentation-only change and were not pursued. The tracked base has no PRD.md (it is ignored), so the old PRD references could not be independently inspected; no runtime tests or other code execution were run.

Verdict

CLEAN — this round found nothing.

[dap-code-review-by-crunchloop]

No open findings on 01e1094.

Approved by DAP code review. The DAP Code Review check run remains the verdict of record; this approval is a projection of it for branch protection, and is dismissed if a finding reopens or a later head is not clean.
