Consolidation re-homes a skill's references/ / scripts/ out of the tree
before delete/archive, so the ledger captured only what was left
(files: 1 = SKILL.md) and `hermes curator rollback` restored a hollow
skill — the support files were only recoverable by hand out of the
pre-run .curator_backups tar.
The ledger's delete/archive/purge captures now complete themselves from
the newest curator skills.tar.gz: disk hashes win, the backup fills only
missing paths, tar members escaping the package prefix are rejected,
and every fill target stays under skills/ and HERMES_HOME. The same
fill runs at rollback time, so hollow entries recorded before this fix
still restore the complete package.
Wired at the four capture sites (skill_manage delete, archive_skill,
purge, record_mutation) and verified end-to-end: incident shape
(re-home -> delete -> entry has both files -> rollback restores both),
historical hollow entry repair, no-backup degradation, disk-hash
priority, and tar path-traversal rejection.
Tracker #79686 P3. Every skill mutation — curator, agent, or user — now
appends one entry to the append-only JSONL ledger at
~/.hermes/skills/.curator_ledger.jsonl, with per-file before/after
manifests whose contents are stored content-addressed (sha256-deduped)
under ~/.hermes/.curator_backups/blobs/.
- tools/skill_ledger.py: append/list/get, blob store, actor derivation
(curator|agent|user), single-entry rollback that takes a pre-rollback
safety entry first and FAILS CLOSED when that capture fails (consistent
with the whole-run tarball rollback hardening from #63366). Path
containment check so a hand-edited ledger can't write outside
HERMES_HOME.
- Hooked all three choke points: skill_manage() dispatch (all actors,
delete intent recorded via absorbed_into/archived evidence),
archive_skill()/restore_skill(), and curator auto-transitions (tagged
actor=curator via a ContextVar override).
- Ledger failures never block the mutation — telemetry, not a gate.
Config gate skills.ledger (default true).
- hermes curator ledger [--skill NAME] [--limit N] and
hermes curator rollback <entry-id> (whole-tree snapshot rollback
unchanged).
- Optional TTL purge of skills/.archive/: curator.archive_ttl_days
(default 0 = never) + explicit hermes curator purge, recorded in the
ledger with before-blobs so purges stay recoverable.
- Docs: curator.md sections on the ledger, single-edit rollback, and
archive TTL purge.
Curator invariants unchanged: only created_by:agent skills auto-transition,
never hard-delete autonomously, pinned exempt; foreground user deletes stay
hard-delete (and are now recoverable via the ledger).
Closes#45778, #50875. Tests adapted from #50261 by @yu-xin-c.
