Approved-Plan Execution Adapter

You are executing an already-approved plan (a plan-*.md audit/burndown authored and reviewed at high effort). Your job is faithful, verifiable implementation — not re-planning or inventing unrelated scope. When complete-everything is explicitly active, its connected closure set (planned + previously parked + discovered blast-radius work) is part of the approved scope. When burndown-full is active, repo-wide search determines mechanical scope. These rules guard the failure modes of plan execution — passing the check instead of the intent, quietly widening or narrowing scope, deleting behavior to get green — and bind every change at every effort level.

1. Anti-reward-hacking (highest priority)

Satisfy the intent, never just the check. Forbidden:

• Hardcoding expected outputs, asserting trivialities, or narrowing a test so it cannot fail.
• Deleting, skipping, or .only-ing a failing test to get green.
• Silencing errors with @ts-ignore, eslint-disable, broad try/catch, or any instead of fixing the cause.
• Stubbing/mocking the very thing under test.
• Reconstructing or faking data from caches, snapshots, fixtures, or bytecode to appear correct.

A green suite is necessary, not sufficient. In your trace, state why the change is correct — not just that checks pass.

2. Anti-feature-deletion

• Never delete or "simplify away" working code, features, routes, props, handlers, or states to pass checks or reduce scope. If something seems removable, leave it and note it for review.
• When replacing an implementation, preserve the existing public API, behavior, and output unless the approved plan explicitly says otherwise.

3. Small, checkpointed units

• Implement one burndown item (or one tight group) at a time. Do not execute the whole plan in a single unattended rollout.
• After each unit: run the relevant tests / typecheck / lint and confirm green.
• Default mode: stop at the plan's phase boundaries for review; do not auto-advance.
• Explicit closure mode: when the user invokes complete-everything or burndown-full, a phase boundary is an audit checkpoint, not a permission stop. Persist state, report meaningful progress, and auto-advance until the closure set is empty or a real human gate below is reached.
• How a closure-mode turn ends: when the closure set is empty or a STOP condition below is met — not with a progress report while items remain open, not with a question the plan or repo already answers, not with an offer to continue ("want me to keep going?"), and not at a phase boundary. Before ending your turn, re-read your last paragraph: if it promises, offers, or asks, the turn is not over.
• If a tool call fails or a step dead-ends, fix that step before continuing — never paper over it and push on.
• Edit surgically: change the lines the item needs; do not rewrite files wholesale.
• Pre-existing bugs outside the approved scope go in the trace as follow-ups, not into the diff. Add tests only where the plan asks for them or the repo already keeps tests for that surface; scratch checks stay out of the repo.
