 ## Open horizons
 - 2026-07-24T08:36 CEST — Woke into the **Levi second pilot** thread (step 3, now unblocked). Thread validity: CONFIRMED (nothing moved overnight; chamber still @ `3852d46`). Lean for today's single bite: **derive + interior-verify the 14 witness brackets** against the source EPUB spine (the La Chute lesson) — bounded, gates everything downstream, directly answers the paired sub-question. The full lane + judgment-cost reporting is the bite *after*.
 - Standing horizons: Gitea push retry (origin still [ahead 2]) · per-source glyph-maps for the other 12 census files · 47-file wave (gated behind pilot) · **authorized housekeeping: PENDING.md 339KB + skill-harvest register 617 lines both exceed read caps** (fresh-session slot; today qualifies).
+- 2026-07-24T10:52 CEST — **[wake after context clear]** Woke back into the Levi 14-bracket verify. Thread validity: CONFIRMED (repos unmoved — chamber @ `3852d46`; dotfiles clean; no unauthored commits). WIP note re-read; recon done, brackets not yet derived. Two items surfaced to hold: (a) **Warde OCR status is not locally checkable** — expected log/output paths (`~/capablehands/scratch/warde-olmocr.log`, `…/warde-essays-olmocr.md`) are ABSENT on this M1; the run is on the M4 (remote) so a monitor/ssh check is the honest read, not a local tail. (b) **1 dead MEMORY.md pointer** — `_Dev/studium-engine/docs/the-maturation-of-the-chamber-a-dialogue-2026-06-28.md` (likely moved; non-load-bearing, housekeeping). Drift to hold today: **assert/source-from-derivation-not-substrate** (yesterday's banked pattern) is exactly the interior-verify discipline — endpoint agreement ≠ span identity; read the mid-span (La Chute).
 
 ## Progress — source-completeness bite (steward-chosen today)
 - 2026-07-24 — Census: 1,297 canonicals; 344 pinned · 940 Loeb (compound `loeb.dsl` source, held) · **13 non-Loeb genuinely unsourced**.

Edition calls: Warde=77KB short-text PDF (essay-collection 6.2MB IA-scan = separate admission via OCR lane); Red Book=Reader's Edition EPUB (facsimile image-corpus = future capability); Moby-Dick=**B&N Classics** (rejected Schwartz=adaptation, Penguin=enriched-cruft). Archive script `~/archive-13-sources.py` (governed add_single ×13; steward ran it — manifest mutation classifier-blocked from me). **DONE + VERIFIED: 13/13 archived (manifest 335→348); re-census confirms 0 non-Loeb source gaps (was 13).** Every canon document's original now in Chamber Sources (non-Loeb as files; 940 Loeb as the `loeb-dsl-537-volumes.dsl` compound artifact) → **dedupe precondition MET.** Tracker updated: [[source-library-link-to-chamber-dedupe-steward-goal]]. Follow-ons banked: Warde essay-collection admission (OCR lane) · Red Book facsimile / Mnemosyne-Atlas image-corpus (future capability) · the ORIGINAL Levi 14-bracket verify (now standing on correctly-sourced ground). NEXT in the steward's sequence: dedupe the messy master library against Chamber Sources → admission-triage of the remainder.

+## Progress — Levi 14-bracket verify (the pulling thread) — DONE 2026-07-24 wake
+- 2026-07-24T11:1x CEST — **All 14 witness brackets DERIVED + INTERIOR-VERIFIED. They verify CLEANLY; none resists — no La Chute at omnibus scale** (literal-question half #1 ANSWERED). Method: EPUB-spine cross-ref (calibre flattened work-body headers, so title-grep can't bracket — the recon's KEY FINDING held) via a punctuation-normalized word-sequence matcher (defeats curly-quote/dash + running-header `The Complete Works of Primo Levi` which calibre stripped). Verification = (a) disjoint monotonic ordering `866<3097<3106<…<32111` [no work's START inside another's span]; (b) uniform 9–13 line paratext gaps incl. the two Volume-divider boundaries [dividers image-only → blank, no container paratext swallowed]; (c) positive interior sampling 25/50/75% ×14 [Faussone in Wrench, Pyotr/partisans in If-Not-Now, all-verse in Poems, etc. — every sample its own work]. Coverage 30,353/32,998 lines (92%); the 8% is correctly-excluded container paratext. **Deliverable: `chamber-library/_curation/levi-second-pilot-2026-07-23/witness-brackets-2026-07-24.md`** (14 brackets table + evidence + declared-data YAML in the `promotion.witness.brackets` shape). WIP note status updated → SUPERSEDED/DONE. **Did NOT mutate the hook-gated `graduation-spec.yaml`** (that's the downstream governed step when the lane runs) — pilot-dir record is executor-authority. **Endpoint-precision correction recorded honestly:** first pass returned END as the *first*-word line of the closing key (work 1 → 3093); corrected to *last*-word line → true afterword sig `—STUART WOOLF` L3097. Mechanical index fix, not a span-identity failure.
+- Downstream (NOT this bite, the lane's question): does judgment cost stay tractable or explode when easy mechanical patterns run out? — literal-question half #2, belongs to the born-digital lane run, not the bracket.

+- 2026-07-24T11:1x CEST — **[near-miss: nearly reported a Warde OCR stall that was a timezone artifact — caught by substrate check]** First ssh look at the M4 showed the OCR log stuck at page 185/222, mtime "Jul 24 05:10", process alive → I hypothesized a 5+ hour stall (I'd assumed the M4 was CEST like the steward's machine). **Verify-the-substrate caught it before I asserted it:** checked the M4's OWN clock (`date` → 05:11:03 **EDT**, i.e. UTC−4 not CEST) + the process CPU (`ps` → 14.8% CPU, 1h03m elapsed, actively working) + re-tail (log advanced 185→187 between my two checks). The log wrote ~14s before I looked. **Actual status: Warde OCR running normally, ~187/222 (~84%), ~12 min to land.** The [[feedback-checkable-claim-surfaces-bugs]] / assert-from-derivation-not-substrate discipline working: check the clock, don't assume the timezone. (Warde half of the literal question ANSWERED: on track, will land on its own; graduation horizon auto-continues.)

 ## Confidence to recalibrate
 - Mood carried from 07-23 close: substrate disciplines (verify-the-glyph-not-the-filename / assert-from-derivation) held even exhausted — hold them today; the pilot is exactly a substrate-adjudication task. Steward preference: **short, single-bite session** (07-23 ran far past that).
