+## 2026-09-03 — 5+3 COUNCIL on the canon entries that shipped unreviewed (#1154)
+
+- **Why convened:** three EPIPHANIES entries + two source-doc blocks sat on an OPEN PR that neither review bot had seen (Codex reviewed only `a1c9488e`; CodeRabbit at its org spend cap). EPIPHANIES is append-only, so this was the last moment the text was amendable rather than permanent-with-regrade — the card's "a spec whose wrong resolution silently corrupts downstream sessions (canon entries)". CI status, merge mechanics and the spend decision were explicitly EXCLUDED from the object.
+- **The 5 (Phase 1, one parallel spawn, read-only):** `prior-art-savant` (Opus — the multi-source lens, ~25.8k lines of EPIPHANIES plus knowledge docs), `iron-rule-savant`, `runtime-archaeologist` (code truth), `cascade-impact-savant`, `creative-explorer-savant` (Sonnet). Panel emphasis declared in the spec: lens 2 pointed at the P0 falsifiability rule and board hygiene rather than the four substrate iron rules, because the object changes no substrate, layout or public type.
+- **The 3 (Phase 3, on draft v2 ONLY, never the raw fan-out):** `overclaim-auditor`, `dilution-collapse-sentinel`, `firewall-warden`.
+- **Verdicts (stricter wins):** Spec PASS · Entry A FIX(P1) · Entry B FIX(P1) · Entry C FIX(P2) · Item D FIX(P2) · Item E FIX(P1) · Board-hygiene FIX(P2) · Gates FIX(P2). **No BLOCK(P0)** — Phase 4 was fix, not re-spec. Firewall: no PII, no secret, no model identifier in added FILE text, ADR-022 not engaged.
+- **v1 → v2:** spec v1's position was "ratify all five as written, zero edits". Five savants falsified it; v2 carried 27 ledger entries. Largest: entry B's "only in a PR body" is FALSE (the same sentence is on the board at `EPIPHANIES.md:355`); entry C is a new INSTANCE of a pattern `preflight-drift-patterns.md` Axis 1 already rules, not a new rule; the corrected census block still was not falsifiable; and **the spec's own F3 citation was stale** (`:555-568` → `:640`) — an append-only board renumbers under every prepend, which is the exact defect entry C is about, committed in the spec written to catch it.
+- **v2 → v3 (what the 3 changed):** entry A's confidence split in two (mechanism High, coverage-table Medium — an absence proves no review COMMENT, not no coverage) and the n=1 mitigation separated from the still-inferred gap; entry A's defect-hedge ADDED alongside the new absence-hedge rather than replaced (the sentinel caught that L5's new evidence made the old hedge necessary, not redundant); entry C narrowed on **provenance** (a value this run computed vs one the author transcribed) rather than on subject matter, which preserved the credibility mechanism the regrade had just named as its only novel part; entry B's evidence sentence corrected — I had widened a savant's `crates/`-scoped grep (0 hits) into "repo-wide" (17 hits), i.e. shipped a false verification inside an amendment about false verifications; item D's deferral restated as "correct but admittedly incomplete"; item E's fix made mandatory after the sentinel showed the alternative horn was already satisfied by shipped text and therefore a no-op.
+- **Two spec-design errors of my own, recorded:** (1) F3's stale citation, above. (2) I gave `git show`-shaped questions to two seats that turned out to have no Bash (the code-truth savant and the firewall warden), so both returned GAP for a mechanical reason rather than an evidentiary one; the orchestrator ran those checks. A future council must match question shape to seat capability.
+- **Gates:** planner lib 411/0, contract `witness_fabric` 46/0, probe exits 0 with `C1 PASS · C2 RESTATED · C3 PASS`, clippy + fmt clean, supersession index regenerated LAST. The new census assertion is disable-verified: removing the delegation in `insight.rs` panics the probe with "found 0"; restored, green.
+- **Escalated, not resolved:** the commit-trailer / model-identifier conflict (see LATEST_STATE). Reviewers were barred from re-litigating it.
+
+## 2026-09-03 — D-DCR-4 consolidation: orchestrator-only, no worker spawned
+
+- **Why:** the census (PROBE-ENTROPY-SURFACE-CENSUS-1) licensed exactly one routing and named its one hazard, so the remaining work was a ~15-line edit plus two falsifiers. Tiering judgment: briefing a Sonnet worker on a spec this precise costs more than executing it — the grindwork/accumulation split says delegate when the brief is cheaper than the work, and here it was not.
+- **Orchestrator:** routed `confidence_entropy` to `thought_atoms::normalized_entropy` preserving the empty-arena guard; wrote the two-sided test pair; ran the disable (delete the early return ⇒ 13 passed / 1 failed on exactly the named test, restored ⇒ 14/14).
+- **Mid-turn:** fast-forwarded onto #1152 (another session's `rubicon-loco-rung-fabric`) and audited the overlap — board-ledger contention only, zero code overlap on `thought_atoms`/`witness_fabric`/`insight.rs`; the one real synergy (their §130 entropy-fragmentation row) is recorded in the epiphany rather than merged into either arc.
+- **Gates:** `cargo test -p lance-graph-planner --lib` 411 passed / 0 failed; clippy `--all-targets` clean; fmt clean (the initial edit needed a reformat, caught by `--check`).
+- **Board:** EPIPHANIES `E-A-RULED-HOME-NEEDS-A-FIRST-CONSUMER-OR-IT-IS-A-VACANCY-1`, LATEST_STATE delta, STATUS_BOARD D-DCR-4, plan W4 gate; supersession index regenerated last.

 ## 2026-09-03 — PROBE-ENTROPY-SURFACE-CENSUS-1: one Sonnet transcription worker, orchestrator-measured
 
 - **Why:** D-DCR-4's gate ("entropy-surface CONSOLIDATION decision recorded first"). Tiering: Opus on the main thread for the census, the fixture design, the three pre-registered claims, the C2 restatement after falsification and both disable-runs; one Sonnet worker for the transcription grindwork (six forms copied verbatim out of unimportable crates, with `file:line` citations), edit-only, no cargo.
