Execute the latest approved plan	builder	github-copilot/gpt-5.4

Execute the latest approved plan for: $ARGUMENTS

1. Read the latest matching plans/<slug> note with Status: approved.
2. Create or update executions/<slug> with the structured sections defined in AGENTS.md (Plan, Execution State, Lane Claims, Last Verified State, Verification Ledger). Set Status: in_progress before changing code.
3. Before parallel fan-out, populate Lane Claims with owner, status, claimed files/areas, dependencies, and exit conditions. Overlapping claimed files/areas or sequential verification dependencies forbid parallel fan-out.
4. Delegate implementation to coder, verification to tester, review to reviewer, and docs or memory updates to librarian where appropriate.
5. Builder owns commit creation during /build: create automatic commits at meaningful completed implementation checkpoints.
6. Reuse existing git safety rules and avoid destructive git behavior; do not add push automation.
7. If no new changes exist at a checkpoint, skip commit creation rather than creating empty or duplicate commits.
8. Record verification evidence in the Verification Ledger using the compact shape (Goal, Mode, Command/Check, Result, Key Evidence, Artifacts, Residual Risk). Default to smoke for intermediate checkpoints; require full before final completion or setting status to done.
9. Follow the plan exactly. If the plan is contradictory, missing a dependency, or fails verification twice, stop, capture evidence, set the execution note to blocked, and send the work back to planner.
10. Before creating the final completion commit, clean up temporary artifacts generated during the build (e.g., scratch files, screenshots, logs, transient reports, caches). Intended committed deliverables are not cleanup targets.
11. Finish by creating a final completion commit when changes remain, then update Last Verified State and set the execution note to Status: done or Status: blocked and summarize what changed.

Automatic commits are required during /build as defined above.
