chore(memory): BDR-044 + LRN-083 + auto-skill-dispatch won't-build — capitalize

Browse Source 
BDR-044: auto-skill-dispatch chantier retired won't-build — 3rd measured moot
of the session (after --help, darwin re-baseline). Cartography showed L1
(superpowers "1%->MUST invoke") already over-determines routing -> reframed
from "does it route" (yes) to DISCERNMENT; risk inverted under->over. Measured
in real fresh sessions (8 prompts/3 classes): clear->route, ambiguous->ask,
trivial->abstain — model discriminates, no over-routing. Adding L2 prose =
phantom value + degradation risk. LRN-083: subagents are an invalid instrument
for measuring main-loop spontaneous routing (SUBAGENT-STOP + delegated framing
pin to the no-route floor) — retired the 0/6 subagent RED. LRN-080 corroborated
(3-in-a-row). TODO -> won't-build. Claude composed all -> trailers (4th
application of LRN-081).

## BDR-044 — auto-skill-dispatch won't-build: under→over reframe, measured — model already discriminates
- **Date**: 2026-06-30
- **Status**: accepted · won't-build
- **Decision**: do NOT add L2 routing prose to CLAUDE.md for "auto-trigger skills on intent". Chantier retired won't-build — 3rd measured moot of the session (after [[BDR-001]] --help + [[BDR-043]]/[[LRN-082]] darwin re-baseline).
- **Why — the dependent variable inverted**: the initial fear was UNDER-routing (model ignores skills, does the task by hand). Cartography refuted it — routing is a STACK and L1 (superpowers "1% chance → you MUST invoke") already SUR-determines invocation → "does it route?" = "already yes". The real open question became DISCERNMENT (clear→route, ambiguous→ASK, trivial→abstain), and the real hazard inverted to OVER-routing. Measured in REAL fresh main-loop sessions (8 prompts, 3 classes): CLEAR→routes ✓, AMBIGUOUS→asks (refuses to guess, investigates to ask a USEFUL question) ✓, TRIVIAL→abstains ✓. The L1-vs-Workflow-rules textual tension ("1% → MUST invoke" vs "ask one question if needed / pragmatic on trivial") is resolved well in behavior — the model balances. Adding L2 bounding prose = phantom value AND risks DEGRADING an already-good discernment.
- **Alternatives rejected**:
- Add a routing-reinforcement instruction (original intent) → phantom value: L1 already over-determines routing; more mandate worsens the only real risk (over-routing).
- Add an over-routing bound (clear→route / ambiguous→ask / trivial→abstain) at L2 → measurement shows the model ALREADY does this; codifying it risks perturbing it, zero upside.
- Keyword hook on intent verbs → too noisy — the design-hook mis-fired on "design" in "auto-skill-dispatch" 3× this session; intent verbs (corrige/crée) are everywhere.
- **Reference**: cartography L0–L4 + discernment-RED (user-run, fresh sessions). Subagent under-routing RED RETIRED as non-discriminating ([[LRN-083]]). [[LRN-080]] (measure-first), [[LRN-049]] (bound noise). TODO "auto-skill-dispatch" → won't-build.
