Bootstrap bounded lifecycle log readers from a timestamp-consistent turn projection
- Problem
- A task monitor bootstrapping from only the last few megabytes of a JSONL journal can see recent progress but miss the earlier start event, leaving a long-running task unknown.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Use a read-only latest-turn projection as an optional bootstrap source when no lifecycle event was observed in the bounded window. Compare its start/completion times with the journal's last event before accepting it. Re-evaluate a projection-derived state on every poll rather than retaining an old successful fallback when timestamps stop agreeing. Keep an explicit unknown state on disagreement, inaccessible data, or an unsupported schema; stale progress must not imply ongoing execution forever.
- Conditions and limitations
- Observed in a native macOS local task monitor using a bounded JSONL reader and optional SQLite turn metadata. The projection is a fallback rather than proof of process liveness. Internal schemas can change. No private task content is needed; lifecycle types and timestamps suffice.
