# Session Ledger — 2026-07-02

## Returns
- 2026-07-02T10:10 — Jonas p248 hold RESOLVED by impact-read, not OCR. Steward sourced a 2nd copy (edition-uncertain). Verified edition identical (anchors A/p247-end + B/p249-note-9 match verbatim). Then read across the gap in the ORIGINAL: p248 held ONLY the "Notes" section-divider title — all note content (Ch1–6 + Appendix) already present & continuous; only ONE illegibility placeholder in the whole raw. No content was ever missing. Inverse of yesterday's contamination lesson: flag was correct, impact never assessed. Caught my own grep false-negative (italic asterisk → 0 for "Immanuel Kant, Groundwork") before trusting it. Findings staged at `_scratch/jonas-p248-recovery/`. Fix = trivial curatorial micro-call (steward): `# Notes` heading vs silent drop of placeholder, then re-run gate + graduate.

## Authorization moves
- 2026-07-02T10:35 — Steward authorized establishing a canonical provenance-source archive OUTSIDE the repo. Created `iCloud Drive / Chamber Sources/` (flat + MANIFEST.md). Moved 4 confirmed originals (Jonas ×2 scans, Vico epub, Heidegger pdf), hashes byte-verified pre/post move, editions verified (Vico=Marsh/Grafton; Heidegger=Hofstadter/Harper). Reversible. Graduations untouched.

## Open horizons
- 2026-07-02T09:34 — Making sources batch (~12 pending, mostly EPUBs) still the pulling thread. Batch graduation needs steward per-source curatorial calls → can't run while steward walks. Prep-that-needs-no-authorization can: EPUB-vs-scan census + finish in-flight candidates (Derrida/Empedocles/Catafalque) to gate-ready.
- 2026-07-02T09:34 — Untracked in chamber-library since clean d9be3e4 wrap: `converted_texts/…/environmental/nature-of-order-vol-1-phenomenon-of-life-alexander.md` + new `_scratch/`. Surfaced, not acted on. The Alexander "Form B unfinished" leftover class.
- 2026-07-02T09:34 — Paper debt: REVIEWED-44/45/46 unplaced (steward deferring to later today per entry).

## Sub-agent dialogues

## Open horizons (end-of-session state)
- **Chamber Sources archive BUILT**: 322 verified source copies (3.3 GB, iCloud, Keep-Downloaded) + 14 Braid/L2 in `pending-graduation/`. Covers ~all of the ~332 non-Loeb canonical corpus (1284 canonical total, 952 = Loeb). manifest.json + INDEX.md; scripts `match_sources.py`+`archive_sources.py` (+ad-hoc census bash — NOT yet scripted).
- **GRADUATION QUEUE = ~12 pending Making sources + 14 Braid/L2** (Nussbaum, Fingarette, Halbertal, Didi-Huberman, Wilson, Smith, Warburg, Neusner, Matilal + multilingual: al-Suyuti/Hadith[Arabic], Kumarila[Sanskrit], Liji/Xunzi[Chinese]). Multilingual subset gated on steward language read + [[feedback-character-as-image-hazard]]. Liji needs both vols; Slokavartika only djvu-txt.
- **TOOL-HARDENING before commit+runbook (steward-agreed, NOT done):** (1 must) script the census completely — Apple Books+Containers, unzipped .epub dirs, .zip archives, diacritic-fold, app-store excludes → `build_inventory.py`; (2) build author-agreement INTO matcher (scoring signal + auto suspects stage; surface ALL candidate editions); (3) Loeb-exclusion; (4) archiver prefer-pristine + handle .zip + auto-verify. Tools UNCOMMITTED in working tree.
- **CLEANUP (later, governed):** remove scattered loose source copies now consolidated in Chamber Sources — EXCEPT Apple Books (steward's travel reading library). Byte-verify each original vs archived copy before removal (recomputed-sha256 gate, like the Tier-A dedupe).
- **Iliad:** Fagles located (Apple Books); no canonical the-iliad — graduate one later (like the-odyssey/Wilson). ON THE LIST.
- **MLA Handbook:** genuinely MIA (not on machine; not Chicago). Stays open.

## Confidence to recalibrate
- 2026-07-02T11:30 — Whole-machine source census + matcher. Phase 1: 9,640 ebooks/PDFs, 38.9GB (inventory TSV saved); ~3,000 book-like after excluding Scores/Pro/admin. Built `scripts/match_sources.py` (internal-metadata + diacritic-fold). v1 = PASS-BUT-FALSELY: 43/59 got candidates but only ~16 solid, ~11 right-author-wrong-work, ~4 false-pos (some high-conf), + false-unmatched (Mencius present, dropped by ≥2-token floor). Logged to tool-evolution-log; v2 fixes scoped. NOTHING committed/moved (steward: "build and run before committing anything"). Held for steward steer on v2 + edition-strictness policy.
- Recalibration inherited from 2026-07-01 ledger: CITE the governed doc; don't re-derive it in a prompt. The rail exists because I re-derived runbook instructions instead of pointing agents at it.

## Bypasses

## Evening session (wake ~21:22)
- 2026-07-02T21:22 — Woke into the evening session (~4h after 17:05 wrap). Thread confirmed unchanged: graduate the queue, file each source into Chamber Sources as a step of graduation. Chamber clean @ `7553f59`; nothing moved. Holding drift-pattern *assume-absent-from-filename-grep*. First move if we proceed: one fast EPUB Making source end-to-end through the rail + archive-as-graduation-step proven once.

### Diagnosis (the evening's real finding) — footnote-apparatus is the batch's binding constraint
- 2026-07-02T~22:30 — Set out to graduate the 7 clean-EPUB Making works (Sebald deferred → Crawford; then steward chose **Sennett reconvert first**). Reconnaissance across all of them surfaced a SYSTEMIC gap, not per-book bad luck:
  - The graduation tooling's footnote converter (`clean_epub_residue.py --mode footnotes`) covers exactly **3 anchor families**: A=Calibre `nfK`/`anfK`, B=`_r?fn-N`, C=`^([..](#.._chNfnN))`. The actual corpus EPUBs use **≥2 more, uncovered**: Crawford = `filepos` page-anchors (286 markers); **Sennett = `{section}fn{N}` / `{section}fn{N}a`** (e.g. `prologuefn1`/`prologuefn1a`, `ch001fn1`; 536 notes, per-chapter numbered).
  - **PASS-BUT-FALSELY trap avoided:** `clean_pandoc_html_residue.py`'s `INTERNAL_LINK` unwrap SILENTLY DESTROYS any surviving footnote-link it doesn't recognize (word-guard excludes fn labels, so loss is uncaught). Its abort-guard only fires on the 3 known families → for Sennett/Crawford it previewed "CLEAN" while planning to unwrap → would have reproduced the exact lost-linkage defect. Caught by previewing, not applying.
  - **Sennett corrected picture:** source EPUB notes are WELL-FORMED (visible `<sup>` in-text markers + verbatim per-chapter-grouped definitions, fully paired by anchor stem). The old canonical's lost linkage was a *calibre* artifact. Reconversion CAN recover it — but ONLY with anchor-aware footnote handling; naive pandoc+existing-cleaners destroys the markers. The 460 `[N](#.._page_N)` "markers" the census first flagged are the INDEX's page-links (drop with Index trim) — a red herring.
  - Census regexes gave two FALSE family IDs tonight (Crawford mis-read, Sennett `chNfnN=536` false-positive). Recalibration: verify the exact anchor STRING in-file before trusting a family-count grep. (drift: assert-from-grep-hit-without-reading.)
- **Durable fix identified:** a GENERALIZED anchor-stem footnote converter — pair `[vis](#..._STEM)` ref ↔ `[vis](#..._STEMa)`/`[vis](#..._STEM)` def by the globally-unique STEM (the principle Family-A already uses), emit `[^STEM]`. Do-once; covers A/B/C + Sennett + Crawford + likely the rest. This is the batch's real unblock. Surfaced to steward for a spend-the-evening call vs. a lighter faithful pass.
- Nothing written to canonical. Sennett canonical file UNTOUCHED. All work in scratch/ (regenerable).

### Family-D footnote handler BUILT + tested (the durable win)
- 2026-07-02T~23:00 — Steward chose "build the generalized converter." Added **Family D (stem-suffix)** to `clean_epub_residue.py`: ref `[¹](#…_{stem})` ↔ def `[N.](#…_{stem}a)`, keyed by the globally-unique stem (embeds section+number, per-chapter-safe). Tested: **Sennett 294↔294, 0 orphans**; regression-tested **Winnicott (B)** and **Virilio (C)** — caught + fixed a real regression (INLINE_STEM captured C's `r`-prefixed def targets `rchXfnY` as phantom D-refs; fix = also subtract the `r`-prefixed C stem-set in verify_pairing). Conversion is order-safe (D runs after A/B/C consume their anchors); only the verify guard needed the exclusion. Uncommitted; needs tool-evolution-log entry + PENDING (extends PENDING-44's rail).
- Filepos-positional family (Crawford, 286 markers) explicitly OUT of scope — different pairing model (ref/def don't share a stem), documented as still-owed in the tool docstring.

### Symmetria check — Sennett heading approach (return)
### CORPUS-QUALITY CENSUS (steward asked: is poor-quality-graduated widespread?) — 2026-07-03 ~00:40
- Ran both gates across all **332 non-Loeb canonical .md** (+ 952 Loeb DSL excluded). THREE axes:
  - **Convention/metadata (verify_graduation):** 8 PASS / **324 FAIL**. ~Universal — but almost all failures are frontmatter/title-block (212 missing req fields, 204 no title-block, 109 NO frontmatter at all, 83 canonical≠true). Only 3 fail a text-content check. Mostly = graduated BEFORE the spec+gate existed (2026-07-01). Mechanical class; not alarming per se.
  - **Text health (verify_conversion):** 222 PASS / **110 FAIL**. ~1/3 have real cruft/OCR/encoding issues — CONCENTRATED in the big OCR'd works: music_performance biographies + Oxford History (Taruskin), the typography/style-guide masters (Bringhurst, Hochuli, Teall, Graves), history tomes (Europe-Davies). This is the genuine quality concern.
  - **Apparatus integrity: UNMONITORED by either gate.** Only 77/332 have a notes/biblio heading — but Sennett PROVES "has a notes section" ≠ "apparatus intact" (its notes existed but markers were stranded/unlinked; 0 refs). Neither gate checks ref↔def pairing or stranded-apparatus. Scale unknown because nothing measures it. Old-schema signature: 26 files `language:` + 11 `conversion_method:` (Sennett-class).
- **Verdict: YES widespread, but 3 distinct problems, not one.** Metadata (mechanical, ~universal), text-health (~1/3, OCR'd works), apparatus (unmonitored, ≥1 broken). The known_gap "audit the ~12 already-canonical" UNDERCOUNTS — it's ~110 text-health + an unknown apparatus tail.
- **Steward directive/instinct: "add apparatus to our audit tools."** AGREED — the unmonitored axis. Proposed apparatus check (verify_graduation extension OR new verify_apparatus): (a) footnote defs `[^x]:` present but unpaired ref `[^x]` → orphan; (b) a Notes/endnotes SECTION present with 0 `[^]` machinery → STRANDED (the calibre-loss signature); (c) ref↔def pairing integrity. Reuse `clean_epub_residue --verify` pairing logic. → NEXT tool-build (not at 1am; deserves its own focused pass). Likely warrants a governed corpus-audit PLAN (the ~110 + apparatus tail).

- 2026-07-02T~23:15 — CHECK on "finish Sennett preserving source heading levels vs full spec-normalization." Named the flag: "preserve levels" is partly convenient (avoids restructuring 129 messy source headings — split `### CHAPTER ONE`+`## Title`, mixed L1–L4 — late at night) AND partly genuinely faithful. Resolution: heading-normalization-vs-faithful-preservation is a CURATORIAL CALL (steward rules those); surface it, don't decide unilaterally. Core defect (lost notes / old frontmatter / `****`) IS fixed by the mechanical pass. Plan: finish approach-INDEPENDENT work (trims + frontmatter + title-block + gate), present near-final to steward WITH the heading question, commit only on their word (avoids do-once rework). Must NOT overclaim "gold bar" — state precisely what was/wasn't normalized.
