+## 2026-10-07 — lance-graph #1391 MERGED; D-PEARL-PROD-0 shipped
+
+- #1391 (`53212db`): Pearl's ladder in production (`lance_graph_planner::pearl::{reason, revise, hydrate}`; `revise(&Measured, Reading)` writes back only to the measured edge). Supersedes the "on branch, unmerged" line in the section below.
+- Contract delta, now on main: `certification` (`CertificationModel` / `ModelBuilder` generic over `PopulationMask`) and `dismech_evidence::{DISMECH_CONCEPT_ID, citation_quorum, CitationQuorum}` (listed under the section below).
+- Planner: `chain_replay`, `chain_counterfactual` (renamed from `dismech_*`, deprecated aliases kept) and `chain_admission` (palette resolved by the classid's concept half).
+- Open: no runtime producer of sealed evidence; demotion policy; what counts as a distinct source; the W2b field map.

 ## 2026-10-07 — lance-graph #1387 and #1390 MERGED; D-PEARL-PROD-0 on branch
 
 - #1387 (`e6612dc`): D-PUZZLE-0 step 3, crossword mask propagation (four arms, cui-bono ablation). #1390 (`6368d8c`): D-PEARL-IO-0 probe, the CE64 upper-half diagram and its comparison page, README picture. No contract change in either.

+## 2026-10-07 — lance-graph PR #1393 (merged `69e661a`, branch `codex/ce64-semantic-upper-half-probe`, head `6c98015`, 6 commits) — D-CE64-SEM-0: a probe-local semantic reading of the CE64 upper half
+
+- **Added:** test-only readings in `pearl_ladder_probe.rs`: bits 46..49 as a signed reaction activation, 50..52 as novelty (`ceil(log2)` of the surviving `EpistemicState5` population; `None` when no state survives), 53..58 as a belief-update breadcrumb. Tests ported onto `planner::pearl` after #1391.
+- **Locked (test-pinned):** 4 example tests: breadcrumb advances only on an Epi5 change, opposite activation signs from one operator, novelty widths 5/2/2/0 plus the contradiction case, direction does not select the operator.
+- **Deferred / open (review findings, PR comment):** each reading reuses bits that already mean something in code: 46..49 is the inference type (activation ±6 aliases Intervention/Counterfactual), 50..52 is plasticity (`network.rs` filters on it), 53..58 is the witness handle (#1371). The tests sit in a `with-planner` example, which CI does not run.
+- **Confidence:** the readings are a candidate only; no layout or accessor changed.

+## 2026-10-07 — lance-graph PR #1391 (merged `53212db`, branch `claude/epistemicstate5-ce64-bits-3oe0dq`, head `9289c46`, 6 commits) — D-PEARL-PROD-0: Pearl's ladder in production, generic over population width, admission keyed by classid
+
+- **Added:** `contract::certification` (`CertificationModel`, `ModelBuilder`, `PopulationMask`: generic over `u64` / `[u64; N]`); `planner::pearl` (`reason`, `revise(&Measured, Reading)`, `hydrate`); `planner::chain_replay`, `chain_counterfactual` (renamed from `dismech_*`, deprecated aliases kept) and `chain_admission` (palette resolved by the classid's concept half); `contract::dismech_evidence::{DISMECH_CONCEPT_ID, citation_quorum}`.
+- **Locked (test-pinned):** the 14 Pearl falsifiers now run in CI in the planner suite; width-equivalence and past-the-first-word tests; classid routing; citation dedup / abstention / two-sided; review fixes (measurement bound to its edge, ungrounded SO, hydrate checks its own path, `Inert` reachable). Each with a disable run.
+- **Deferred / open:** no runtime producer of sealed evidence; demotion policy; what counts as a distinct source; the W2b field map.
+- **Confidence:** high for the rules as pinned; the counterfactual fixture is one measured chain and never reaches `Inert`.
