- [Session 2026-07-06 evening — Olson GRADUATED; tool-integration audit; A2 pending](session-2026-07-06-evening-olson-graduated-tool-audit-A2-pending.md) — Completed the Olson graduation from the structure checkpoint: extended `insert_chapter_headings` (occurrence + MODE + **title-oracle** extent; first tests, fleet **46→64/64**; steward chose the MODE-column fork), built the ~73-row structure map, **removed a blank-page scan-noise region** (verified blank verso; whole-file `ocr_damage` was blind to it — a localized PASS-BUT-FALSELY), **graduated** → `canonical_texts/…/the-power-to-name-olson.md` (73 headings, both gates PASS, **0 body words dropped**), archived source + `source_verified`, catalogue 1293. Evidence-over-intuition: the naive normalize glue-fix over-blocks 288 lines (verbatim guard blind → PASS-BUT-FALSELY) → glue resolved at insert-time. Then a steward tool-audit **RETRACTED a misdiagnosed log entry** + chose **discipline-over-bloat** for the one real gap (`graduation-spec integrity.localized_scan_noise` + docstring fix); recorded [[feedback-completion-is-a-tripwire]]. (A2 SETTLED + FILED as PENDING-50 in the 2026-07-06 evening#2 session.)

- [Session 2026-07-06 pm — Olson graduation executed; structure-insertion checkpoint](session-2026-07-06-pm-olson-graduation-executed-structure-checkpoint.md) — Executed the Olson *The Power to Name* graduation (REVIEWED-49 A2 primary source) from the staged orientation. **Built + tested a general `normalize_ocr.py --pdftotext` scan mode** (form-feed→page-marker; case-agnostic page-top-recurrence furniture detection; blank-gap reflow) — verbatim guard **PASS** (86,408 tokens), fleet **46/46**, backward-compatible (all gated behind `--pdftotext`); tool-evolution logged. Extracted the clean verbatim body, then a **scan-verified + fail-loud-logged OCR-correction pass** (`≠` restored p.177; `Anzaldúa`/`Cherríe` p.193; `Luiseño`/`Farmer`/`able-bodied`/`I hope`; 6 furniture-residue lines) — candidate clean+faithful. Near-miss caught: most "noise" short-lines are CONTENT (LCSH BT/NT/RT/UF codes). **CHECKPOINTED at structure insertion** — steward chose the **full-structure path**; wrap→clear→wake→resume there. (Structure insertion + graduation COMPLETED in the 2026-07-06 evening session.)
