- N-batches: validation report note on the transient DuckDB spill directory during N13
- N8: rule-based baseline (snapshot rules.py) vs LLM on a stratified seeded sample of 60,000 ledger sections; rules-on-full vs rules-on-focused recall-loss bound
- N5: focus-window coverage of every ledger section (shown fraction, last offset, gate hits shown, plateau, short MD&As)
- N12: environment lock of the master node venv (uv pip freeze, 88 packages), .python-version 3.12.15, environment.md
- N1: ledger reconciliation (gate pass / true call count, backfilled block, outage, collisions, logs, throughput)
- WP44: landmark selection v2 (read-only DuckDB, dedup, venue and abstract filters)
- WP44: semantic scripts read-only (DuckDB lock)
- WP44: corpus v2 metadata (7.11 M core works), configurable DuckDB memory
- memory: release Arrow buffers between symbols, smaller DuckDB limit, faster stale requeue
