Archive a completed change. cospec archive validates it, merges its spec deltas into the living specs, verifies the move actually happened, and fans blocker check-offs out to sibling changes — as one coupled step.

1. Select the change

If the user named one, use it. Otherwise run cospec list --json and pick, or ask.

2. Archive

cospec archive <slug>

Relay the summary it prints verbatim: what was archived, which spec deltas were applied (+a ~m -r →n) or skipped, which sibling changes had blocker boxes checked, and which changes are now unblocked.

3. On failure

If it exits non-zero, relay the error output verbatim. Do NOT hand-mv the change directory into openspec/changes/archive/, and do NOT re-run with a flag you do not understand:

• "archived nothing (exited 0 but aborted)" means the spec deltas did not apply — fix the delta errors it printed, or, if this change genuinely should not touch specs, re-run cospec archive <slug> --skip-specs.
• Incomplete tasks block the archive. Finish them, or re-run with --force-incomplete only after the user confirms the remaining tasks are intentionally abandoned.

Never bypass validation. If a change is reported as now unblocked, offer to /cospec:apply it next.
