db.Audit() satisfies audit.Storage (all 17 methods) over SQLite: one indexed
row per run (+ a JSON inputs blob), one row per log event. Filter/list/walk
queries are indexed on the columns they filter (skill_id, caller_id,
parent_run_id, started_at); WalkParentChain follows parent_run_id with a
seen-set guard; LastRunBySkills is a grouped MAX.
Test covers run start/finish round-trip (inputs map + token roll-up), log
append + ordered read, parent/child + ancestor-chain walks, caller listing,
TopLevelOnly filter, and the last-run-per-skill map.
contrib/store now backs ALL four store seams — budget + persona + skill + audit
— so a host gets turnkey durable persistence (run history, budgets, agents,
skills) with zero store code. Core go.sum still has 0 sqlite refs.
