dx-archive

Retire a finished container. One id in, one folder moved, one stamp written. No registry — the archive is just where done work lives.

Guard. If the id resolves to nothing, or the folder can't move cleanly, do nothing and say why. Never half-move.

Resolve

The argument is one id. Find its home:

• context/changes/<id>/ → it's a change.
• context/efforts/<id>/ → it's an effort.
• Neither, or both → fail loud: print what you looked for and stop. (Already under context/archive/? Say it's already archived.)

Effort gate — children first

An effort is done only when every child change is already archived. Before moving an effort, read its roadmap.md, and for each linked child change check for archived_at (derive it — scan the child's change.md, don't trust a checkbox). If any child is still open, list them and ask before continuing. The user may override.

Review gate — unresolved findings

For a change, check reviews/impl-review.md. If it has any finding with Resolution: PENDING, warn — "N unresolved impl-review finding(s) — /dx-review-triage impl to address them first" — and ask whether to archive anyway. The user may override.

Move and stamp

1. Destination: context/archive/<today>-<id>/ where <today> is date +%F. If it already exists, fail loud and stop.
2. Stamp the moved container's change.md (or effort.md): set status: archived and archived_at: to today's date (date +%F, same format as created/updated — no other field in the schema carries a finer timestamp); bump updated:. Leave every other field alone. For the exact schema, invoke dx-references with topic change-md (a change) or effort-md (an effort).
3. Move the whole folder: prefer git mv so history follows; fall back to mv (warn) if git is unavailable. Confirm the source is gone and the destination exists — if not, print a diagnostic and stop.

Done when

The folder lives at context/archive/<today>-<id>/, its identity file reads status: archived with archived_at set, and nothing remains under the old path. Print:

✓ Archived <id> → context/archive/<today>-<id>/

If it was an effort, add one line noting how many child changes it closed. Then suggest a next step (/dx-new <idea> to start fresh) and stop. Do not chain.
