 - [Be (laundromat)](project-be-laundromat.md) — canonical workstream tracker established 2026-06-08 (Seb-relay of locked decisions). Be = Skemantix startup (Seb+David) funding CapableMind's funding-ladder; **bridge, not venture**. Decisions LOCKED: entity/exit (CapableMind decoupled, grant-funded), pricing (Living $12.99/mo · Archive $69.99/yr · Memorial $49.99/yr · Renovate ~$199 · $8.99 floor), CF Self-Serve Agency + versioned-template-package infra. **a11y gate MERGED (Pat 100/100/100).** Pre-revenue: the WTP gate = renovate Pat → charge her. **Discipline: stop adding spec until the gate clears → nothing for executor on be until then.** Repo @ `f43a0fd`.

Built `embed_spike.py` (bge-m3): **cross-lingual PROVEN** (`gift↔le-don 0.823`). **THE DILUTION CORRECTION (heart of the day):** steward's MemPalace Class-B memory → my first verdict over-corrected to voice-scope-only → steward's **depth-WITH-breadth** correction ("the library one enters into discourse with"; the slice = thin PoC) → corrected verdict: whole-corpus semantic IS the goal; dilution = engineering (clean corpus + **retrieve-broad/rerank-sharp cross-encoder = Seb's C1 pattern** + thresholded connection-finding + measured-at-scale); **vector = discovery breadth, FTS = citation floor.** **Audit:** 46-agent spec-code audit → **foundation SOUND** (87 matches, invariants held under adversarial tampering; 20 minor survivors · `a978ab6`). **Chamber:** cleaning-triage workflow (223 dirty → 25 cleanable/127 reconvert/71 hold) → **23 graduated** to canonical_texts (now 199/218 · `9fea743`). All pushed. **PULLING THREAD: Step 7 proper — the cross-encoder RERANKER (retrieve-broad/rerank-sharp over the bge-m3 sidecar) as the dilution-beating discovery layer, toward whole-corpus depth+breadth.** Studium `main @ a978ab6`; L1 baton shared (Seb to review #174).

Then **Studium Steps 3 (chunker) + 4 (store+FTS5+coverage ledger)** — both verified against substrate: **Weber-non-leak**, **deterministic rebuild ID-equality** (Class-A non-fatal, criterion #1), byte-faithful, **paratext non-indexable**, every line classified→**silence warrantable**. **10 commits / 3 repos, all pushed.** **PULLING THREAD: brief L1 detour FIRST — Seb's reply landed in CapableMind-AI (`cc25995` reply + `e2e94ab` cover note, now in local main) — THEN return to Studium Step 5 (retrieval primitives: honest-empty + coverage warrant).** Studium `main @ b3274c4` clean+pushed; Steps 0–4 done.
