First Tier-2 battery, plugging into run.Ports.Audit:
- storage.go/writer.go: skillaudit's Storage interface + per-run Writer moved
clean (only utils->fmt); the Writer already matches run.RunRecorder's shape.
- sink.go: Sink adapts a Storage to run.Audit (StartRun -> a run row + a Writer
wrapped as run.RunRecorder, converting run.RunStats on Close). NewSink(nil) is
equivalent to no audit. Compile-time proofs: Sink is run.Audit, recorder is
run.RunRecorder.
- memory.go: NewMemory() — a zero-dependency, queryable in-process Storage
(retains runs + logs; all 17 read/filter/purge/walk methods) so a light host
gets run history with no setup. Mort keeps its GORM Storage; contrib/store
adds durable SQLite at P4.
End-to-end test: wire audit.NewSink(audit.NewMemory()) into the executor, run an
agent, and the run is recorded with terminal status/output and queryable by
caller. CI invariant verified: core imports ZERO from the audit battery (proper
battery direction; battery imports core, never the reverse).
