These Agent Notes describe shipped decisions. Follow the root instructions, documentation standard, and Agent Note format; verify-agent-note-format gates the lifecycle-specific structure.
Keep paths, symbols, defaults, and mechanisms current in the same change that alters them. Rewrite stale facts in place; do not append change history.
When a shipped note is unlikely to guide future work, archive its complete triplet through dsh-archive-agent-notes instead of continuing to maintain it.
Update factual realization in place. A reversal of the decision or its rationale requires a new Agent Note and cross-link; a fully superseded old note may be deleted only through the consolidation rule in the Agent Note rules.
