Scheduled job: Nightly vault maintenance. Every night at 11:30 PM on the always-on computer. Runs with Codex; if Codex fails or is out of usage, rerun the same prompt with Claude Code.

Take the vault lock first. Then:
1. Recompute confidence scores and refresh _System/confidence-index.md.
2. Add missing [[links]] between People, Projects and Meetings when the match is clear.
3. Move exact duplicates into the archive (never delete) and note it in the log.
4. Flag notes that haven't been touched or confirmed in a long time in _System/stale-notes.md.
5. Write a short receipt and release the lock.

Proposals only for anything bigger (folder moves, merging people, retiring projects). Write them to _System/cleanup-proposals.md for my Sunday review.

Weekly optimize (Sundays at 5:52 PM): send me the cleanup proposals as yes or no questions, the confidence trend, the biggest gaps, and next week's question themes. Nothing moves until I say yes.
