Auto-fix removed extraneous f-string prefixes, unused imports
(re, sys, textwrap, defaultdict), an unused local (qids), and
converted datetime.now(timezone.utc) to datetime.now(UTC) (UP017).
Manual fixes split colon/semicolon one-liners onto separate lines
(E701/E702), renamed unused loop vars (cid, chain_id) with leading
underscores (B007), replaced bare except with except Exception (E722),
and renamed loop var L to level to satisfy N806.
Loads the published corpus (via vault_cli.policy — single source of truth)
and chains.json, buckets by (track, topic), and emits chain-coverage.json
with two cuts:
- uncovered_buckets: ≥3 questions, 0 chains
- under_covered_buckets: ≥6 questions, ≤1 chain
Plus per-track summary + top-10 uncovered for quick read.
Output is gitignored — regeneratable, fed to Phase 1.4's --buckets-from.
Phase 1.1 of CHAIN_ROADMAP.md. See progress log for the run results
(211 uncovered buckets, edge/mobile/tinyml chain density 0.6-0.8 vs
cloud's 2.95, biggest miss is cloud:roofline-analysis at 144q/0 chains).
