+## PENDING-42 — Chamber Library spec ratified (§§I–VI); open voice-layer work
+**Date:** 2026-06-26
+**Tag:** [PROPOSAL] (the open items); the ratification itself was authorized live and is recorded here for the paper loop
+**Summary:** The Chamber Library spec (`chamber-library/docs/chamber-library-specification.md`, born 2026-06-25) was carried through the full steward + jurist loop in conversation and ratified §§I–VI; the spec file is now edited to the ratified text. This entry records what was authorized and holds the remaining open work.
+**Ratified (applied to the spec 2026-06-26):**
+- **§§II–III** — source-agnostic canonical form + the `work + chapter/section + verbatim quote` citation contract, **plus** the jurist's sectionless reduction (a sectionless work cites by `work + verbatim quote`; a missing section field is correct, not a defect).
+- **§V** — the verbatim guarantee, three-tier normalization (Remove / catalogued-normalization / never-alter-words). Resolves the spec's prior internal contradiction: **"verbatim" = faithful to the words under *declared* normalization, NOT byte-identity** (§II already permits transforms). Executor refinement folded: **minimize the catalogue** — prefer preserving source characters; typographic normalization permitted only on concrete need, never prophylactically (tighten-the-verifier, Charter §VII).
+- **§VI architecture** — two sidecars: reading-index (derived, hash-bound) + voice manifest (authored, engine-side, no hash); `voice: <name>` stays in corpus as a routing tag; **the sole corpus-spec invariant: the grounding gate verifies only against canonical text, never a manifest/index.** Grounded in existing practice (4 `reading-indices/*.yaml` already embody the pattern).
+- **§X** — antechamber clause (sub-canonical form not guaranteed; consumers must flag distinctly). §VII gate logic found already conformant (no edit).
+**Rationale:** A corpus the engine cites from confidently must have a specified, consistent form, or the engine reasons over silently-varying ground (Charter §V boundedness=trust; the L1 maxim). The ratification unblocks the held graduation of the first three spec-conformant texts.
+**Open work (awaiting future authorization — NOT done):**
+1. **Voice-manifest schema** — controlled vocab, authorship governance, engine consumption model. **Engine-governance**, not corpus-spec; lives with the studium-engine charter. Orchestration thinking captured at `studium-engine/docs/the-sidecar-typology-and-orchestration-2026-06-26.md`.
+2. **The 84-file voice migration** — move `voice_role`/`semantic_profile` from canonical frontmatter to the manifest. A governed, **dry-run-first** bulk op; not a prerequisite to the principle.
+3. **`voice_tradition`/`voice_period` usage audit** — decide per-field migration target (work's compositional context → §IV provenance; persona flavor → voice manifest). Owed before the migration.
+4. **§IX** coverage/silence representation — still open.
+**Recommendation:** Build the two normalizers (OCR + EPUB → one canonical form) next, apply to Levi / Alexander Book 4 / *La Chute*, commit the first spec-conformant graduation. The open voice-layer items are deferred and do not gate graduation (the graduates need conform only to §§II–V + the citation contract, not the undesigned manifest schema).
+**Files affected:** `chamber-library/docs/chamber-library-specification.md` (ratified text applied); `studium-engine/docs/the-sidecar-typology-and-orchestration-2026-06-26.md` (new, exploration).
+**Awaiting:** Steward to write **REVIEWED-45** to close the loop on paper (the authorization was given live in conversation; like REVIEWED-44 for operations.yaml, the paper record is owed).
