Close: Block D

Arguments: $ARGUMENTS. The first is the issue number; epic means this closes an epic.

1. Script part

Run node .claude/scripts/close.cjs <n>. It deletes nothing it can't prove is safe:

• the PR must be MERGED
• the working tree must be clean
• the local branch tip must equal the merged PR's head

Exit codes:

• 3 (aborted): report its message and both SHAs to the owner, and stop. Don't delete anything by hand.
• 2 (error): report it and stop.
• 0: go on. Its report lists what it deleted and the memory files that mention the issue.

2. Model part

• Condense each memory file the report lists: keep the outcome, the deferred follow-ups and the lasting lessons; drop the step-by-step. Don't delete a memory that other work still needs. Make the edits; don't ask first (D4).
• On epic: run one knowledge audit. Brief the red-team to check the ADRs and docs the epic touched against the code's current behaviour. Its findings come to the owner like any others.

3. Report

One short message:

• what the script deleted and kept
• the memory files you changed, each with one line on what you condensed
• the audit result, on epic

The issue comments (plan and handoff) stay as the record.
