# Session Ledger — 2026-07-05

## Returns

- 2026-07-05T11:53 — Wake. Thread validity gate run before synthesis: CONFIRMED (no overnight movement; repos + dotfiles clean). Verified built-state and git state against the substrate rather than inheriting the June record — carrying last session's twice-held trust-prior-pass-frame reflex.
- 2026-07-05 — **Verify-before-asking:** the jurist's diplomatic-vs-modernized flag — resolved against the actual source files (glyph census: zero long-s/fold-ligatures/soft-hyphens across all gold) rather than assumed or relayed back as a question. Modernized → flag moot at present gold; caveat recorded for future diplomatic gold. Uses reach proactively (CLAUDE.md) instead of adding a round-trip.

## Open horizons

- **Engine (build day, Opus):** V0 + N0 — the two contracts, together (plan §7). V0 = verifier contract + pre-registered thresholds → routes to the jurist (the one named D-1 exception). N0 tree contract must exist before any hand touches the Loeb extractor rebuild (reciprocal obligation, §3.4). N1 can proceed while V0 sits with the jurist.
- **Corpus:** Region 1.1 — the exclusion path, test-first, surfaced for jurist ratification (chamber corpus-work-map-2026-07-05).
- **Held literal question:** normalizer@N "unaltered" — engineering (D-1) or doctrine ("the bound must name the edition")? Will the jurist gate V0 clean, or does "what counts as the same words" surface an unanticipated ruling?
- REVIEWED entries owed for the PENDING-46/47 chamber arc.
- Skill-harvest backlog awaits a steward authorization pass (last full review 2026-06-05): notably `/model-handoff` (proven end-to-end last session) and `studium-engine tool-evolution-log` (home for V4's pattern-finder retro-gate review).
- MemPalace 3.3.6 → 3.5.0 available (layers wake-recency fix #1630; likely wing-filter #1665). Read: hold through build day, run scheduled upgrade at a break.

## Confidence to recalibrate

## Authorization moves

- 2026-07-05 — **PENDING-48 filed** (`~/PENDING.md`): routes Studium V0 (verifier contract) to the jurist as a method-gate — the one named D-1 exception (rebuild-plan §8.5). Two decisions surfaced, leans given not decided: §2 the "unaltered" equivalence relation (the held literal question; lean (B) normalizer@1, flagged possibly-doctrine); §5 the pre-registered V2 thresholds (CP-upper-bound; small-n honesty). **Held at the boundary: no V1 code.**
- 2026-07-05 — V0 drafted (`studium-engine/docs/spec/v0-verifier-contract.md`, DRAFT-awaiting-jurist) + N0 drafted (`docs/spec/n0-navigation-tree-contract.md`, D-1, inhabitable, no jurist gate). Both grounded in code read this session (normalizer@1, sidecar schema, coverage-ledger warrant), not the plan's prose. **Uncommitted — commit+push held for steward's word** (studium is D-1 direct-to-main; not explicitly asked to push).
- Contamination watch honored: did not let V0 silently decide the doctrine question (surfaced with lean, marked jurist's); thresholds presented as pre-registered-pending-gate, not settled; resisted the pull to build V1 past the boundary.
- 2026-07-05 — **Jurist gate CLEARED (both §2, §5), with conditions.** Ruling recorded at source, not just relayed: V0 DRAFT→v1.0 (Ruling section); the **`fidelity_equivalence@1` fork** landed in `cluster-a-data-model.md` §5.1 (doctrine split visible at source, per the ruling's explicit instruction); PENDING-48 closed (REVIEWED entry owed). Standing conditions carried: proportional-expansion rule (§5), display↔threshold coupling (§5), diplomatic-gold caveat (§2). V1 + N1 now unblocked. Then committed+pushed on steward's word (studium `4140fad`, dotfiles `70ad599`).
- 2026-07-05 — **Shift to chamber. Region 1.1 exclusion path BUILT + TESTED (`[agentic + flag]`).** Diagnosed the pin mechanism, traced the archiver consumer (conf=="high" → excluded records ignored, no archiver change), built test-first: attested-absence via `source_verified.result: confirmed-wrong|none-on-disk`; positive-attestation guard preserved. 37/37 tests (7 new), full real-corpus run byte-identical (inert → zero regression). Surfaced for jurist ratification (PENDING-47 sub-entry); **held from real canonicals** until the pattern is ratified. Uncommitted.
- 2026-07-05 — **Exclusion path RATIFIED-WITH-CORRECTIONS; §1 corrections applied (Phase A).** Jurist required two corrections, both right (closed default-by-absence gaps): (1) exclusion → its own honest key `source_excluded:` (not a verdict inside `source_verified:`); (2) `result: verified` explicit+required on pins → migrated the 5 existing pins. Shared guard `_valid_attestation` (defined once). 37/37 green, matcher byte-identical (5 pins still honored). Recorded per the ruling (PENDING-47 updated; FOR-JURIST banner). **Region 1.2 now `[agentic]` with diff-before-commit** — held for steward go + the none-on-disk evidence standard. Uncommitted.
- 2026-07-05 — **Region 1.2 APPLIED + committed.** Steward "yes and yes" → attested the 4 FPs. Verify-against-substrate CORRECTED the map: all 4 are `confirmed-wrong` (concrete wrong candidate on disk), not 3 none-on-disk — incl. reverie's same-author-wrong-work `suspect=False` blind spot. Instrument-B 0/5 evidence each; source-matches.json change provably bounded to the 4 (315 others byte-identical). Diff surfaced → steward "reads right" → committed+pushed the exclusion arc. **Region 1 CLOSED (known cases).** NEW: frontmatter-sweep-at-scale surfaced ([needs-authorization]; scope-first; honesty constraint = no fabricated provenance).
