The wave-8 N-1 deferred item — re-read the three unconditional-growth
paths against the implemented engines and land the decision of record:
all three accepted for v1, per engine, with no engine-side hygiene.
- deployment.md: new 'Growth postures (consciously accepted)' section —
per-engine table (dead letters sweep-on-call, SQLite-only notify
at-attach cap, durable-log stream posture; mem process-lifetime-
bounded by design) + the rationale and the deployment-matrix
fold-in positioning.
- engine-sqlite.md: 'Notifications-table hygiene' — attach is the only
prune site (D-16, oldest-first 10k); idle-but-listening processes
never prune; the cadence caveat deployers should size for.
- tasks/release-n1-growth-posture.md: completed; Notes/Summary filled.
