recover always exits 0, even when recovery attempt fails.
This weakens the “scriptable/cron-friendly” behavior because callers cannot detect a failed recovery attempt. Also, extra args are currently silently ignored.

Review NotesNice minimal change — exposing existing recovery logic as a first-class command is the right approach. A few things to address before merge: Rebase requiredThis branch is 77 commits behind main. Notably, PR #2398 (
No architectural overhaul needed — just a rebase. Blockers
Suggestions
Tests pass ✅ against the PR code. Overall this is a clean, well-scoped change — just needs the rebase and the two fixes above. |

Thanks for the thorough review! Will rebase onto latest main and address both blockers (indent regression + temp dir cleanup in tests). I'll also add proper typing to the test file and implement the exit code propagation — that's a great suggestion for the scripting/cron use case. |
