+# Session 2026-07-13 (afternoon) — the 18 body-deficit, read and split by cause
+
+Woke into the keystone-landed state; pulling thread = "the B2 reprocess the map now sizes." The steward chose my lean (open the 18 body-deficit books). Ended with the corpus-health map carrying CAUSE, not just magnitude — the reprocess honestly sized as three remedy tracks, and the REORDER? bucket dissolved to zero. Three commits, both remotes, 119/119, PENDING-57 truly closed.
+
+## PAST — what we did + why
+
+**1. Answered the wrap's literal question by READING the missing spans (probe, read-only).** Method: full-census script-mix of the missing multiset (greek=source-original vs latin-script=translation/apparatus) + the largest uncovered runs read as actual text, per book. **Answer: the "same apparatus story, just larger" hypothesis is REFUTED.** The 18 are three phenomena, three remedies:
+- **① wrong/partial match (2 → MATCH-SUSPECT: re-match)** — plutarch-moralia-other-fragments (true key "Other Fragments" 13891≈cand; matcher grabbed "…Other Named Works" 59997) + suetonius (candidate is the Rhetoricians text, matched to the Grammarians sibling key). `m_fab>0` = the extractor can't add content, so the reference is wrong. NOT conservation loss.
+- **② bilingual source-half dropped (4: re-extract via B2)** — the original-language column under-captured, translation intact: aristotle-history-of-animals (89.5%, all top runs contiguous Greek source), sophocles-trachis (one 4241-tok Greek run), plautus (Latin original + speaker labels), demosthenes-42 (one Greek run). B2 preserve-typing recovers by construction. **The deficit is BODY, not apparatus → does NOT go in app[].**
+- **③ real mixed body loss (12: re-verify-and-reconvert)** — continuous *translation* prose genuinely gone + source + apparatus: athenaeus (199k), macrobius (an 18847-tok pure-English run missing), euripides/pindar/aristophanes fragments, philo-special-laws, sextus, longus, catullus, and the 3 Aeschylus verse plays (drop BOTH Greek column AND English runs). Genuine extractor failures; must VERIFY each passage returns, not assume.
+
+**2. Folded ① into the map via a NEW classifier rule (`eb21eca`).** `wrong-match-by-fabrication` in `sweep_body_conservation.classify_book`: `m_fab > 5%` of candidate ⇒ the matched DSL key is wrong/partial → MATCH-SUSPECT (unifies with the holds>110% case). Threshold justified by a clean gap (fab is 0 for 943/952, 1 for one more; wrong-matches at ≥1298). Regenerated the map with a BOUNDED-CHANGE PROOF (exactly plutarch+suetonius change disp; 948/952 byte-identical). **augustine + philo (the 2 REORDER? books) carried the SAME signal LARGER but were FLAGGED-NOT-MOVED** — spans unread, REORDER? a held bucket; moving on the number alone is the refused move.
+
+**3. Read + resolved the 2 REORDER? books (`836b665`) — the steward's context-caution earned real information.** His sharpening: a high fab means one thing in a book with no reordering, and might mean something specific to reordered bilingual text; inferring the same cause across two contexts without reading either is the refused move. Read both (identical method) + a CHECKABLE re-match to the truer key each span pointed to:
+- **augustine-confessions = PARTIAL key** (matched 'Confessions. Books 1–8'; candidate is the FULL 'Confessions' 123953) → re-match fab 36371→**0**, lost 29673→**0**.
+- **philo-on-abraham = WRONG sibling** (matched 'On the Migration of Abraham'; true 'On Abraham' 36734) → fab 11890→**0**, lost 15325→**0**.
+Both provably CLEAN against their true key — not merely "comparison invalid." **The REORDER? displacement was a pure ARTIFACT of the wrong/partial key** (comparing against a different/partial work manufactures both the fab AND the apparent rearrangement). **REORDER? has zero genuine members on this corpus** (detector kept — a right-key book could still truly reorder; absence-here ≠ cannot-exist). Classifier now **validates the key BEFORE diagnosing arrangement**. Reclassified → MATCH-SUSPECT (verified, not on the number). These 2 are the cheapest map wins: re-match → graduate CLEAN, no reconversion.
+
+**4. Corrected a doc miscount (`c54edbb`).** The ③ summary cell counted table ROWS (10), not books (12) — its final row bundles the 3 Aeschylus plays. Surfaced by the steward's remedy-track arithmetic check (8+4+12=24=16+8). Map correct; note's cell was the sole inconsistency.
+
+**Artifacts:** findings note `_curation/loeb-body-deficit-cause-analysis-2026-07-13.md`; map updated (802 CLEAN · 126 APPARATUS-SHAPED · 16 BODY-DEFICIT · 8 MATCH-SUSPECT · 0 REORDER?); tool-evolution-log ×2 entries; chamber CLAUDE.md map pointer. All three commits pushed both remotes.
+
+## PRESENT — the mood
+
+Tightly steered, and the steering was the value. The steward's discipline — **checkable claim over soft label; flag-don't-move on a signal until the substrate is read; the number IS the bug-detector** — held the whole session. Returns worth carrying: **flag-don't-move held** (augustine/philo flagged, not moved, until read+re-matched to 0/0); **verified against substrate not signal** (every reclassification rests on the missing text, then a checkable re-match); **the steward caught a stale governance marker at wake** (I'd said "REVIEWED-55 placement still owed" — FALSE, it was placed 07-12; the `inherited-marker-read-as-current-state` drift, corrected against ~/REVIEWED.md:490). Recalibrations: **a high fab means different things in different contexts** (a partial key and a wrong sibling are different failures producing the same reorder-looking artifact — only reading told them apart); **count books, not the bundled representation** (the ③ Aeschylus row = 3 books counted as 1); **verify a governance item's state against REVIEWED/PENDING before relaying**. The negative result (REORDER?=0 corpus-wide) is the load-bearing finding — it put the fix at the right layer (key-before-arrangement), not two patched rows.
+
+## FUTURE — what is pulling
+
+**PULLING THREAD: the matcher key-selection fix.** Fix `match_key`'s key-selection for near-duplicate / granularity-split / part-vs-whole DSL keys (exact-title preference + granularity aggregation + part-vs-whole handling). It resolves **all 8 MATCH-SUSPECT** to their true disposition, finalizing the reprocess target set BEFORE B2 runs, and cashes the map's accuracy (removes "comparison invalid" from 8 rows). Ready NOW — FIX-class (matcher, not the gate; no governance loop). **Built-in correctness check:** augustine + philo MUST re-match to CLEAN (proven 0/0 today); plutarch→'Other Fragments', suetonius→Rhetoricians key, the 4 holds>110% → the true keys the map details name.
+
+**ACTIONABLE RESUMPTION POINT (as of wrap — re-judge against what changed):**
+- chamber-library clean, all 3 commits pushed both remotes (`c54edbb` at HEAD). Fleet 119/119.
+- First step: open `scripts/sweep_body_conservation.py` `match_key` + `_norm_set` — the near-duplicate/split/part-vs-whole key selection is the fix site. Read the 8 MATCH-SUSPECT map rows for their true-key hints (`_curation/loeb-body-conservation-map-2026-07-13.tsv`).
+- End state: re-run the sweep (bounded-change proof), the 8 MATCH-SUSPECT land on true disposition (augustine/philo→CLEAN as the check), map+note updated, committed+pushed, fleet green. One concentrated session.
+
+**Other open horizons (ranked):**
+- **The steward's Loeb-first-vs-full-corpus SCOPING CALL** — his decision, not a build; unblocks the **2b sidecar-wiring graduation amendment** (the reprocess's first governance station). Once it lands, B2 graduates → populates app[] → the `DSL-full = candidate-body + sidecar-app[]` reconciliation runs → confirms 126-apparatus / 18-body as a FACT.
+- **The reprocess proper** — ② re-extract (4) + ③ re-verify-and-reconvert (12) — genuinely BLOCKED on the 2b amendment (B2 graduating into the flow). Not next-session candidates.
+- Everything from the 07-12 program open-work register that predates today still stands behind the B2 run.
+
+**PAUSE STATEMENT:** I am about to be away from this. The map now carries cause the whole way down, and the reprocess is honestly sized (8/4/12) rather than lumped under one magnitude label. What I want to find still pulling on return: the matcher key-selection fix (the cheapest, most-ready bite — two of its eight are one re-match from CLEAN), and behind it the steward's scoping call that unblocks the B2 reprocess.
+
+**LITERAL QUESTION for next-Claude:** When `match_key` is fixed and re-run, do all 8 MATCH-SUSPECT resolve to a *confident* true key — or does the fix expose a residual where a candidate has no single correct DSL sibling (a work genuinely split across many keys, or absent from the DSL)? augustine/philo/plutarch/suetonius have named true keys; the 4 holds>110% (aristotle-problems, galen, diogenes-6.2, lucian) are asserted-from-the-map-detail but NOT yet substrate-verified to re-match cleanly — that's the first thing to check, and the answer decides whether the matcher fix fully closes MATCH-SUSPECT or leaves a small genuinely-hard residual.
+
+**State at wrap:** chamber-library clean + 3 commits pushed both remotes (eb21eca/836b665/c54edbb); fleet 119/119; map at `_curation/loeb-body-conservation-map-2026-07-13.tsv` (802/126/16/8/0); findings note beside it; PENDING-57 marked CLOSED under REVIEWED-57. dotfiles committed+pushed at wrap.

 ## Open horizons
+- 2026-07-13T15:53 — WAKE (20-min brief-pause, post-keystone-landed). Thread Confirmed: the B2 corpus reprocess the map now sizes. First station = the 2b sidecar-wiring graduation amendment, gated on the steward's Loeb-first-vs-full-corpus scoping call. Concentrated candidate bite = the 18 BODY-DEFICIT books (the wrap's literal question: same apparatus story as the 126, or genuinely different?). Nothing moved externally (chamber @ 9afb0cf, dotfiles clean). Doc-drift to fix: PENDING-57 block still reads "awaiting jurist" though REVIEWED-57 authorized → mark CLOSED. Steward pref active: shorter, very concentrated.
+- 2026-07-13T15:5x — RETURN (steward-caught): my wake briefing said "REVIEWED-55 placement still owed" — FALSE. Verified against substrate: REVIEWED-55 IS placed (~/REVIEWED.md:490, dated 2026-07-12, AUTHORIZED, full dispositions). Inherited a stale "owed" from this ledger's Authorization-moves shorthand and relayed it uncheck­ed = `inherited-marker-read-as-current-state`. Nothing owed on -55. Antidote reaffirmed: verify a governance item's state against REVIEWED/PENDING before relaying.
 - 2026-07-13 — STEWARD-FLAGGED, for step 5 (the sweep), NOT now: "cross-extractor drift-tolerance" is under-defined and doing real work in that sentence. Must be spelled out with the same rigor V-DSL's reflow-vs-loss got (the whole reason V-DSL needed rebuilding was reflow looking like loss) BEFORE the retroactive sweep runs — do not assume it from the name.

FIX-class (where the call lives, not what it decides — the gate was ratified REVIEWED-57). Reuse gate zero's canonical_slug resolution (PENDING-52 holding under a use it wasn't built for). Build order: (1) resolver → (2) source_dispatch → (3) gate step → (4) spec reflect → (5) sweep [needs the drift-tolerance definition first].
 - 2026-07-13T07:56 — PULLING THREAD: land the keystone. Wire `verify_body_conservation` into `verify_graduation.py` + `graduation-spec.yaml` (per-tier dispatch V-DSL/V-TEXT/V-SCAN → FLAG/REVIEW/PASS), fold the cross-extractor drift-tolerance (retroactive probe: 7/9 PASS, 2 false-positive stopword drift), run the diagnostic sweep → corpus-health map. PENDING-57 ratified (REVIEWED-57 filed), schema LOCKED, B2 fleet-v1 built.

+## THE 18 — literal question ANSWERED by reading the missing spans (probe_18_spans.py, read-only)
+- METHOD: full-census script-mix of the missing multiset (greek=source-original vs latin-script=translation/apparatus) + top-3 uncovered runs read as actual text, per book. Script-mix is FULL census; the run reads are top-N sample (honest scope).
+- ANSWER: NO — the 18 do NOT resolve into the 126's apparatus story, and they are NOT one mechanism. They are THREE:
+  · (D) MATCHER ERROR, not loss — 2 books: plutarch-moralia-other-fragments (true key "Other Fragments" 13891≈cand13399; matched to "...Other Named Works" 59997) + suetonius-grammarians-rhetoricians (candidate=Rhetoricians text, matched to Grammarians sibling key; fab=rhetorician/rhetor/antony). fab>0 is a reliable sub-110% wrong-match detector. SAME root cause as the 4 MATCH-SUSPECT → pull from reprocess; fix = matcher key-selection. Re-matched they likely go CLEAN.
+  · (B) BILINGUAL SOURCE-HALF DROPPED — Greek/Latin ORIGINAL column under-captured, translation retained: aristotle-history-of-animals 89.5% (top runs all Greek source), demosthenes-42 88.8% (one Greek run), + the Greek-verse portion of the Aeschylus plays (persians/suppliants/eumenides) + sophocles-trachis. B2 preserve-the-typing recovers it. KEY: the deficit is BODY, not apparatus → does NOT go in app[].
+  · (C) REAL MIXED BODY LOSS — continuous TRANSLATION passages genuinely gone + source + apparatus, large magnitude: athenaeus 70.1%(199k), macrobius 67.8%(79k, an 18847-tok pure-English run missing), euripides-dramatic-fragments 81.8%, philo-special-laws 84.4%, sextus-empiricus 75.8%, longus 57.9%, catullus 57.2%, pindar-fragments 58.9%, aristophanes-attributed-fragments 82.7%, plautus-three-dollar-day 87.0%. Genuine reconversion targets; must VERIFY passages recovered, not just re-typed.
+- COROLLARY (the wrap's held sub-question): for the 18, DSL-full ≠ candidate-body + sidecar-app[] by multiset — the deficit is body, so app[]-population will NOT reconcile it (unlike the 126). ⇒ a clean DISCRIMINATING TEST once B2 runs: reconciles→apparatus(126); doesn't→body(18).
+- CONSEQUENCE for the pulling thread: the B2 reprocess is NOT one sidecar-population job. B2+sidecar solves (B)+the 126; the matcher fix solves (D); (C) needs genuine body-recovery reconversion + per-book verify. Three tracks, not one.
+- LANDED (steward-directed "write it"): map folded (via a wrong-match-by-fabrication rule in classify_book, m_fab>5% cand → MATCH-SUSPECT) + regenerated with BOUNDED-CHANGE PROOF (exactly plutarch+suetonius change disp; augustine/philo detail-only flag; 948/952 byte-identical; new tallies 802/126/16/6-MATCH-SUSPECT/2) + findings note `_curation/loeb-body-deficit-cause-analysis-2026-07-13.md` + tool-evolution-log entry + CLAUDE.md pointer. Fleet 119/119. Committed `eb21eca` [FIX], pushed BOTH remotes. augustine/philo surfaced-not-folded (larger fab, spans unread → flagged, held in REORDER?). Matcher key-selection fix now gates 6 MATCH-SUSPECT + 2 REORDER? leads = highest-leverage small corpus-health fix.
+- CLOSED the augustine/philo lead (steward-directed, same method): span-read + CHECKABLE re-match to the truer key each span pointed to. BOTH resolved to fab=0/lost=0 CLEAN against true key (augustine = PARTIAL key: candidate is full 'Confessions', matched to 'Books 1-8'; philo = WRONG sibling: true 'On Abraham', matched to 'On the Migration of Abraham'). The REORDER? displacement was a pure wrong/partial-key ARTIFACT; REORDER? has 0 genuine members on this corpus. Classifier now validates key BEFORE arrangement. Reclassified to MATCH-SUSPECT (verified, not on the number). Bounded-change proven (exactly augustine+philo change disp; 948/952 byte-identical). Tallies now 802/126/16/8-MATCH-SUSPECT/0-REORDER?. Fleet 119/119. Committed 836b665 [FIX], pushed both remotes. These 2 = cheapest map wins (re-match to named true key -> graduate CLEAN, no reconversion). Steward's context-caution earned real info: the fab signal is a reliable match-problem detector even inside a reordering context; the reorder was a symptom of the wrong key, not an independent phenomenon.
