The file is INTERLEAVED — a naive split-at-first-`## Archived` was caught-and-avoided last time. Surgical only; wake-canary (every pointer + [[link]] resolves) after the move.
 - 2026-07-06T13:29 (post-clear, /wake-up) — Resumed on the singular pulling thread: **finish the Olson *The Power to Name* graduation right-once** (from the staged GRADUATION-STATE.md) → A2 verify off the clean text (Ch 6) → A2 preamble. Inherited the prior wrap's load-bearing return as the governing tension: **do the 92.5K-word verbatim graduation with fresh attention, not crammed to "get to A2"** — the chamber's thesis is that a rushed-but-plausible text is worse than none. Infra loose end closed while away: chamber github mirror first-push landed (`4c5892e`, task exit 0). To sweep at next wrap: `~/dotfiles` has an uncommitted `M REVIEWED.md` (the REVIEWED-49 placement).

+- 2026-07-06T15:52 (post-clear #2, /wake-up → Symmetria init) — Resumed on the singular thread with fresh context, by steward's deliberate wrap→clear→wake choice: **complete the Olson structure insertion via the full-structure path** → frontmatter → gates → graduate → A2. First move: fix Phase-1 heading-glue in `normalize_ocr.py` (add `not is_runhead_candidate(prev)` guard to the forward-rejoin, guarding `out[-1]`) → re-run → re-apply `.OCR-CORRECTIONS.md` set → occurrence-index extension to `insert_chapter_headings.py` → ~50-row structure TSV (fail-loud dry-run, iterate). Governing tension inherited verbatim: **fresh attention on the ~50 anchors, not crammed; the fail-loud dry-run is the net — don't guess past an ambiguous anchor.** Drift to hold: `census-through-a-pattern` + `trust-prior-pass-frame` (both live in the anchor-TSV). dotfiles clean at wake (prior `M REVIEWED.md` already swept). MemPalace origin/main @ 3.5.0 (recency fix #1630 + HTTP hardening) — HOLD until post-graduation per standing plan.

 ## Confidence to recalibrate
 - 2026-07-06T15:1x — **LCSH-notation catch (near-miss, named).** Almost characterized ~200 short lines as "OCR noise" to strip; the census revealed most are CONTENT — LCSH thesaurus codes (BT/NT/RT/UF = Broader/Narrower/Related/Used-For), list markers, subject-heading examples — in a book ABOUT subject headings. Blind stripping would have destroyed content (PASS-BUT-FALSELY). Cleanup reduced to a small scan-grounded fix set; genuine speckles left verbatim (spec: uncertain→leave).
 - Cleanup DONE + logged (`the-power-to-name-olson.OCR-CORRECTIONS.md`): ≠ restored (scan p.177), Anzaldúa/Cherríe (scan p.193), Luiseño/Farmer/able-bodied/"I hope", 6 furniture lines dropped. All counts fail-loud-asserted.

 - 2026-07-06T14:0x — Steward PROBED the framing (would an olmOCR-class rescan solve the structural/layout problem, then just single out eccentricities?). Answered with substrate evidence: pdftotext preserved the crown jewels (Dewey reformed-spelling block PERFECT; "confuzion" in-context; "Ite/arating" ×25 w/ 2-3 OCR variants) but LOST "≠"→"#" (one heading). Key reframe: eccentricity-verify-against-scan is unavoidable under ANY path (pdftotext already lost one) → rescan doesn't remove that step; and the layout-fix faculty (VLM semantic linearization) IS the fidelity-risk faculty (silent normalization of the exact A2 misspellings) — trades a bounded/detectable casualty list for an unbounded/silent one. **Steward RULED: proceed faithful (pdftotext + guarded furniture-strip).** Fidelity-doctrine-adjacent methods call, steward-decided.
 - REVIEWED-49 received (jurist doctrine pass on PENDING-49), captured in chamber-library/docs/library-science-adoptions-RULING-2026-07-06.md. **NOW PLACED in ~/REVIEWED.md** (verified at wake — full entry present; supersedes the earlier "grep=0 / not yet placed" note). Executor owes verify-don't-assert before drafting A2: (1) engine hot-path read `retrieve.py`; (2) verify Olson vs the primary source *The Power to Name* (2002) — citing the scout's characterization would repeat A4's error.
 
+## Returns (structure-insertion session — post-clear #2)
+- 2026-07-06T16:1x — **Challenged the checkpoint's own framing.** The staged plan said "fix Phase-1 glue + occurrence index." A census (all ~50 heads vs the body) showed it was FOUR sub-problems: glue, occurrence, prose-adjacent heads that `heading_block` strands, and absent heads (6 chapters + Notes as running-head furniture). Surfaced the fuller picture + the one governed-tool fork to the steward (AskUserQuestion) before touching the shared tool; steward chose explicit MODE column. Didn't execute the under-described plan.
+- 2026-07-06T16:3x — **Measured before committing; the intuitive fix was wrong.** The session's literal question assumed fixing the Phase-1 glue in normalize_ocr. Empirically tested the naive guard → it over-blocks **288 lines** (~276 legit prose/quote first-lines, incl. the Dewey reformed-spelling crown jewels), and the verbatim guard PASSES both runs (word-level → blind to a reflow-split = PASS-BUT-FALSELY). Rejected the upstream fix; resolved glue at insert-time instead. Evidence (288-line diff) over intuition.
+- 2026-07-06T16:5x — **Title-oracle over-extension caught in the real dry-run.** `replace_extent`'s shape-based head-extent grabbed a short wrapped PROSE line ("The consistent marginalization…") into the 3rd CONCLUSION — shape can't tell a wrapped head-continuation from a short wrapped prose line. Fixed: the curator's declared TITLE is the extent oracle. Pinned by a regression fixture. (measure-the-render / dry-run-before-apply paid out.)
+- 2026-07-06T17:0x — **LCSH near-miss avoided AGAIN.** A gibberish-run scan flagged 8 runs; inspection showed only 1 was real garbage (a blank-page scan-noise verso, verified by viewing PDF p.74 = blank gray) — the other 7 were CONTENT (LCSH BT/NT/RT/UF codes + a German endnote). census-before-stripping held; the drift the prior session logged did not recur into action.
+- 2026-07-06T17:3x — **git mv silently no-ops on an untracked candidate** — graduate_to_canonical reported success-shaped output but moved nothing the first pass (candidate never committed → not under VC). Verified the file actually landed in canonical_texts rather than trusting the tool's summary. live-state-discipline.

+## Returns (tool-integration audit — steward "are we certain / least that does the most?")
+- 2026-07-06T18:5x — **Steward's "are we certain?" caught a MISDIAGNOSED tool-defect in the log.** I'd logged "git mv silently no-ops on untracked" as a graduate_to_canonical defect. Verified against the code: FALSE — the tool git-adds untracked sources + falls back to rename + fails loud (fixed 2026-06-16). Tried to pin the real cause of the one-off first-apply non-move → **refuted 3 hypotheses empirically** (untracked-git-mv; SIGPIPE buffered; SIGPIPE unbuffered — a prints-then-writes probe through `head -5` completed the write in every mode). Honest verdict: tool correct, mechanism UNKNOWN. Retracted + corrected the log entry. Don't re-log a mechanism as fact without reproducing it.
+- 2026-07-06T19:0x — **Chose discipline over tool-bloat (steward filter applied).** Was about to propose a windowed ocr_damage gate for the localized blank-page garbage. On reflection: it needs a dictionary dependency, cries wolf on codes/tables/verse (my ad-hoc version fired 7 false positives on Olson's LCSH content), and the human triages anyway → single-use bloat. **Fixed the recurring gap WITHOUT bloat:** (1) added `integrity.localized_scan_noise` discipline to graduation-spec.yaml (spot-read boundaries + scan-verify + census-then-inspect; records WHY it's a discipline not a gate, so future-us doesn't re-propose the bloat); (2) corrected the verify_conversion docstring that overclaimed "windows" (it's whole-file — the overclaim briefly fooled me). Both inert-verified (YAML parses, gate PASS, fleet 64/64).
