# Session Ledger — 2026-06-14

## Returns
- 2026-06-14T (measurement writeup pulse): caught a confidence-without-evidence shape — about to write that the global-condition reranker "demotes gold from #1 by swapping a thematically-adjacent passage into #1," but had NOT inspected what the reranker actually placed at #1 in H1/H3/H10. Returning to verify ONE demotion case (read the rerank #1 text) before the report characterizes it. Also holding: give the global hit@1 regression (−0.045 overall, −0.214 Harrison) EQUAL billing to the wins; n=22 single-essay — don't generalize to "reranker is good," say "on Essay I's 22 measurable citations." Reranker built+measured = the pulling-thread first move is DONE (voice-scoped ΔMRR +0.152, recall@20 1.0/0.909).

## Open horizons
- 2026-06-14T (wake): PULLING THREAD — Step 7 proper, the cross-encoder reranker (retrieve-broad → rerank-sharp) over the bge-m3 sidecar; the dilution-beating discovery layer, toward whole-corpus depth+breadth. First move: pick the cross-encoder model (check Ollama; reuse Seb's C1) → prototype → measure precision vs unreranked on concept queries.
- HOLD TODAY (yesterday's load-bearing return): solve-constraint-by-discarding-value — keep depth-WITH-breadth, never re-narrow to voice-scope.
- L1: PR #174 + issue #173 OPEN, no Seb review yet — baton with Seb.
- Small queued: re-sweep chamber cleaning with the hardened strip_cruft (la-terre + man-s-search now graduation-eligible).
