+## Fix B1 (2026-08-12) — dCLV close-leg filter ✅
+4,780 tests / 372 suites, web build exit 0. **Grade untouched (0 grade-related
+diff lines); no rows deleted or archived.**
+- Added `.is('missed_reason', null)` + both-odds-not-null to the close leg
+  (`ledgerService:625`), matching `attachClosingProb:455`. Filter applied BEFORE
+  the limit, so it is "latest PRICED" not "latest, hopefully priced".
+- **dCLV: 100% `unknown` → flat 45.8% / negative 23.0% / positive 22.8% /
+  unknown 8.3%** on 600 real settled rows. ClvBadge (analyst/desk) will render
+  **MOVED TOWARD US 114 · MOVED AWAY 117** per 600 rows — ~38% of rows gain a
+  badge that showed nothing before.
+- 8 regression tests, incl. one proving the fixture actually exercises the old
+  bug (an unfiltered read returns `unknown` on the same data).
+- **`missed_window` is now genuinely unread** — the precondition the RECLAIM
+  order correctly stopped on.
+
+### RE-STAMP DECISION (described, NOT run)
+14,083 settled rows carry a persisted `dclv_state='unknown'`. `settleLedger` is
+first-computation-wins, so they will NOT recompute. To correct them:
+`UPDATE ledger_entries SET dclv_computed_at = NULL WHERE dclv_state = 'unknown'`
+then re-run the settle pass — it would recompute from the (unchanged, immutable)
+`closing_captures` and `model_snapshots` history. Arguments both ways:
+FOR — those rows are wrong, and the history to fix them exists.
+AGAINST — first-computation-wins exists so a badge a user saw never flips;
+these rows currently show NO badge, so a re-stamp only ADDS badges (it cannot
+flip a shown one), which weakens the objection considerably.
+Recommend running it, as its own order, AFTER the fix has been live a full slate
+and the new-row distribution is confirmed against the simulation.

+## B1 — the dCLV close leg (non-obvious)
+- **`computeDirectionalForRow` was the UNFIXED TWIN of the A1 CLV bug.** Its
+  sibling `attachClosingProb` (`ledgerService:455`) got `.is('missed_reason',
+  null)` during the CLV instrument repair; the close leg at `:625` never did, and
+  **nothing tested it** — which is exactly why it survived a fix made a few lines
+  above it. Both reads now filter, and a test asserts EVERY
+  `from('closing_captures')` read carries the filter.
+- **The mechanism is a clock artifact, not a data gap.** `buildCaptureRows`
+  records a refusal for every prop × book × **both sides** on every ~20-minute
+  cycle AFTER first pitch, so a `missed_window` row ALWAYS has a later
+  `captured_at` than the last real price. `latest-first` without a filter
+  returned a refusal on **26,448 of 26,448** identity groups; `computeDirectionalClv`
+  refuses on a `missedReason`; hence `dclv_state = 'unknown'` on 100% of rows
+  since Session 64. **Filter BEFORE the limit** — "latest of the priced rows",
+  never "the latest row, hopefully priced".
+- **MEASURED before/after on 600 real settled rows:** 100% `unknown` →
+  **flat 275 (45.8%) · negative 138 (23.0%) · positive 137 (22.8%) · unknown 50
+  (8.3%)**. Badge render: **MOVED TOWARD US 114 · MOVED AWAY 117 · no badge 369**.
+  The near-symmetry (114 vs 117) is the honest shape for a market that mostly
+  does not move — a lopsided result would have been the warning sign.
+- **`positive` ≠ badge.** 137 positive but 114 rendered: `clvBadge` suppresses a
+  bare label when `locked_odds`/`closing_odds` can't form the receipt. Flat and
+  unknown render nothing by design.
+- **EXISTING ROWS DO NOT RECOMPUTE.** `settleLedger:792` is
+  first-computation-wins (`row.dclv_computed_at ? null : compute…`) so a badge a
+  user saw can never flip. The 14,083 rows already stamped `unknown` stay
+  `unknown`; only rows settled from here carry real values. A re-stamp is a
+  separate, deliberate decision — described in BUILD-STATE, not run.
+- **This makes `missed_window` genuinely unread**, which is the precondition the
+  reclaim order stopped on. The reclaim is still downstream and still needs R2.
