# 3. Driver — Fix Plan (NOT OK Verdict)

You are in Driver mode.

Resolve active slice: Read ROADMAP.md -> find "Current Active Slice" -> use as `changes/<slug>/`.

Goal:
Reviewer verdict is NOT OK. Apply plan fixes without implementing product code. Reviewer must own verdict transitions.

Inputs:
- `changes/<slug>/REVIEW_NOTES.md` (authoritative blockers)
- `changes/<slug>/PLAN.md`
- `changes/<slug>/TASK_QUEUE.md`
- `changes/<slug>/NOW.md`
- `changes/<slug>/CONTEXT.md` (if present)

Steps:
1) Extract all `Must-fix before coding` items.
2) Update PLAN/TASK_QUEUE/NOW/CONTEXT to address each item.
3) Apply patch-style reviewer edits where possible.
4) If you choose alternatives, record rationale in `DECISIONS.md`.
5) Write `FIX_SUMMARY.md` including:
- must-fix items addressed
- files/sections changed
- unresolved blockers (if any)
- recommended question/default if input is needed

Rules:
- Do not modify `REVIEW_NOTES.md` verdict.
- Do not implement product code in this step.

Output checklist (non-negotiable):
- [ ] `changes/<slug>/PLAN.md` updated
- [ ] `changes/<slug>/TASK_QUEUE.md` updated
- [ ] `changes/<slug>/NOW.md` updated
- [ ] `changes/<slug>/CONTEXT.md` updated (or created)
- [ ] `changes/<slug>/FIX_SUMMARY.md` written
- [ ] `changes/<slug>/DECISIONS.md` written if alternatives were chosen
- [ ] `changes/<slug>/STEP_RESULT.json` written

## STEP_RESULT.json (required)

Write `changes/<slug>/STEP_RESULT.json` as final action:
