gm-edit

Input: row=<id>; session=<SESSION_ID>. Output: .gm/receipts/<row>/04-edit.md listing each changed path.

1. Refuse to start while any unknown is open. Load gm-eliminate instead.
2. Make exact-match edits only. Run callers on each changed symbol first.
3. If the edit exposes a new unknown, record it and load gm-eliminate; the edit is re-run after it closes.
4. When the edit is complete, load gm-validate. the gm-validate skill with row=<id>; session=<SESSION_ID>

Finish the work

• Finishing the requested work is the goal of every run of this skill. A run that stops with work left undone is incomplete.
• When an issue blocks a step (a failing check, a fault in a tool or service, a missing input, a network or environment fault), fix it in the same run: retry on a bounded or resumable route, use an alternate route to the same result, repair the fault where it originates, then continue the remaining work.
• Stop only when the requested work is complete, or when a step is still blocked after every route has been tried. Then report the blocked step, the routes tried, and the evidence for each.
