 - 2026-07-04T12:20 — Audit-agent on the Explore recon (audit-agent discipline). Two load-bearing corrections against substrate: (1) agent's "graduate_to_canonical MISSING verify_conversion" is STALE — Wave 0 (f9cbb8e) wired both gates (lines 36-37); agent inherited pre-Wave-0 status from the compliance doc (records-drift-both-directions flag). (2) agent stopped one step short on seam 1: the ~1% FP estimate is derived from the matcher's OWN `author_disagrees` signal (self-agreement), which fires ONLY when the canonical surname is ABSENT — structurally blind to same-author-wrong-work (Bachelard Reverie→Espace, 60%) and whole/part (Proust whole→vol-III, 62%; Levi work→complete-works), both sitting UNFLAGGED in the 321 confirmed. This is the exact structural error of the "74% anchorless" premise. Verified by reading match_sources.py source, not the report.
 
 ## Open horizons
+- 2026-07-04T23:00 — **Fable-5 planning session init** (the wrap's planned handoff; ~7-min pause). Sole deliverable: `studium-engine/docs/stage-1-rebuild-plan-2026-07-05.md` from the scope-charter (`stage-1-replan-scope-charter-2026-07-05.md`), then report-and-stop. Literal question held: does the prior stage-1 plan conflict with the v0.3 charter (navigate-don't-retrieve + two-tier verifier), and is the verifier-organ buildable now on Instrument B? Flag to hold: trust-prior-pass-frame (recurred 3× today) — read both docs at the scope of the claim before ruling conflict-vs-slots-cleanly. Multilingual-validation gate must not be skipped.
 - 2026-07-04T12:05 — Corpus stress-test (thread confirmed at wake). First artifact = pre-registration doc (thresholds before data). Dependency order: source-matching reliability FIRST (independent, not self-agreement) → order-sensitivity (inject known-bad) → disambiguation edges. Small-batch before full 2,041. NOT single-perspective.
 - Literal question held open: does the ~1% source-match false-positive hold under INDEPENDENT test, or is it optimistic like the "74% anchorless" premise was?

 ## Authorization moves
 - 2026-07-04T12:30 — Pre-registration doc drafted (`docs/corpus-stress-test-pre-registration-2026-07-04.md`), status DRAFT. Per its own §4, execution awaits steward/jurist confirmation of thresholds (pre-registration is void if revisable after seeing data). Surfacing to steward for threshold confirmation + jurist-first decision. Seam-1 grading to PROPOSAL/ESCALATE = normative (gate-change) → the loop is load-bearing here.
 
+- 2026-07-04T23:55 — **Steward ruled all five §8 points inline ("agreed on all points" on the executor's leans):** (1) compose-reading CONFIRMED (+ code-enforced motion boundary); (2) fence posture CONFIRMED + tightening (tier labels mandatory from V1's first output); (3) order RULED V0+N0-first-together, then verifier-leads-with-interleave; (4) fingerprint core RULED technique-shared/code-separate (rule of three; notary = the future third consumer); (5) V0 RULED jurist-routed — the one named exception to engine D-1. Rulings recorded INTO the plan §8 (artifacts-are-the-handoff), committed + pushed `d968241`.

 ## Sub-agent dialogues
 - 2026-07-04T12:45 — Jurist gate on the pre-registration = GATE-WITH-METHOD-CHANGE. Sharpening not rejection; every point landed. The Q2 statistics catch (point-estimate grading lets a 5%-bad corpus read clean ~40% of the time) I should have caught myself — verified P(0or1|.05,40)=0.399 before encoding the CP-upper-bound fix. Four revisions applied, doc LOCKED v1. Jurist also caught a quiet scope-narrowing I'd made (Loeb "no risk" vs "different risk") → Seam 1-bis. Good instance of the loop catching what one pass missed.

 - 2026-07-04T21:00 — Chamber wrapped (6 commits pushed). Pivoted to STUDIUM-ENGINE deep research (steward's choice, "after the substrate"). 6-front fan-out + built-on the 2026-06-27 prior sweep (107 agents) + the charter (v0.2). Produced: charter-update v0.3 proposal + research evidence base (`studium-engine/docs/…-2026-07-04.md`, uncommitted). Key syntheses: two-tier grounding (quoted=byte-existence-GUARANTEE via boundedness / synthesized=measured); verification-easier-than-generate does NOT transfer to a single LLM judge → deterministic-or-ensemble verifier; debate-is-theater→ground-voices-in-retrieved-passages+preserve-tension; measured-confidence (semantic-entropy); evidence-only human display; the edition-aware gate the jurist demanded is NOW provided by v2 work-identity; genealogy = composition-not-invention (4-layer stack, MPIWG-Sphaera nearest kin, semantic-conflation the risk). **THE OBLIQUE FIND (steward's Q): the whole AI-citation market checks metadata-existence NOT verbatim-fidelity-at-anchor → the corpus's unique capability = DEFERRAL ("searched vs deferred-to"); notary/callable-primitive/content-credentials-for-text.** STEWARD PUSHED to re-run the stalled retrieval agent through the v2 lens → REAL SURPRISE: "navigate-don't-retrieve" (2604.14572) — the engine's CTS/DTS tree IS the authored navigation structure a 2026 frontier result must distill; retrieval = navigate-the-tree not embedding-top-k = the literal §II inversion. My "confident it's covered" was a rationalization of the stall; steward's instinct was right. Both surprises integrated into the charter update.
 
+- 2026-07-04T23:45 — **Fable session deliverable produced: `studium-engine/docs/stage-1-rebuild-plan-2026-07-05.md`** (uncommitted; report-and-stop per scope charter). Literal question ANSWERED: no genuine prior-plan↔v0.3 conflict — built Steps 0–7 stand; the unbuilt tail resequences (verifier organ first, retrieval reshaped tree-primary, dialogue behind both). Three apparent conflicts each resolved by composition: (a) defense-#9 construction vs post-hoc verifier = compose (construction primary, verifier covers synthesis + defense-in-depth); (b) embedding-demotion vs steward's depth-with-breadth = two-motions reading (grounding-retrieval navigates / discovery keeps breadth, verifier-gated) — FLAGGED for steward confirmation, touches his own 06-13 ruling; (c) fence vs empty-verified-tier = dev-on-slice-with-tier-labels, fence activates with ledger column — FLAGGED. Verifier IS buildable now (Instrument B = technique-seed, honestly not drop-in: document-containment ≠ span-existence); only canonical-anchor granularity + classical-language validation wait for Loeb Region 4. Trust-prior-pass-frame held: built-state verified against repo (grep `_balance_by_work`, manifest count 21), not the June record; navigate-paper's +19% explicitly NOT claimed before N3 measures it on our corpus. Charter path slip noted (chamber-library/PENDING.md → ~/PENDING.md).
