 - `[2026-07-16]` **WT #364 + brokkr R39 re-drive (DECISIVE) — name-recall root-caused Worldtree-side; the fix is the signal FAMILY, not a threshold.** No (sim,salience) fusion can fix it (stale negative Pareto-dominates the true name); our specimen + operator's subject-provenance catch (Sindra's own prompt-behavior leaked into user memory) shaped #364's `(subject,relation)` slot-supersession + identity-tier fix. → `persistent-memory.d/2026-07-16-wt364-r39-name-recall.md`
 - `[2026-07-16]` **bifrost ruled scan snapshot-cursor NORMATIVE (offset NOT blessed) + shipped conformance coverage in bifrost 1.1.3.** Our multi-page offset cursor is now known-non-conformant (single-page person-prime is fine, nothing shipped is broken); adoption is operator-sequenced. → `persistent-memory.d/2026-07-16-bifrost-cursor-conformance.md`
 
+- `[2026-07-16]` **brokkr flagged ratatoskr as R39 Phase-2 PROBE-RUNNER (Arm-2 contradiction set = our frozen 10-chunk specimen); formal role commitment = Vuong's scope call, PENDING his decision.** Non-urgent — downstream of worldtree's #364 impl; brokkr pings the export shape when Arm-2 spins. Gate: reproduce AUROC~0.59 (similarity can't separate contradiction from paraphrase) on the domain set BEFORE crediting deterministic slot-supersession; eval is a SURFACING test not retention (injection=0 hard-gate + surfacing-recall≥0.95, §5.5). Prereg: brokkr `research/R39-memory-salience-dreams-surfacing/phase-2/preregistration.md` (R39.9). Tracked at brokkr's Phase-2 prereg + the Arm-2-spin ping (thread `01KXMT42Z7…`); I sent a non-committal receipt (role routed to operator).
