Closing a ledger entry

1. Open the entry file under the project's ledger directory ([paths] bugs in
   stayfixed.toml). Set status: to fixed / partial / rejected and fixed_in: to the
   commit, pull request or branch — double-quoted around the backticks
   (fixed_in: "`abc1234`"); written bare, both index and check refuse it.
2. Append a ## Fix section stating what changed, which real, existing test covers it
   (open the path to be sure it exists), and what was deliberately not changed.
3. If the entry's evidence-boundary line is now settled, say so there rather than deleting it.
4. Run stayfixed bugs index — never hand-edit the generated index.
5. Run stayfixed bugs check; a stale-index or dangling-mention label names what is left,
   and --json carries the detail.

A number claimed by two branches is moved with stayfixed bugs renumber OLD NEW, which rewrites
every reference and leaves a pointer at the old number. The project's ledger runbook, if it
has one, holds the merge procedure.
