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

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.

 - **pattern**: the --help chantier (implement [[BDR-001]] as a global CLAUDE.md instruction "on --help → render help + stop") was KILLED by its behavioral RED. Before writing a line, measured the control (6 reps, `/web-validate` + `/harden`, no instruction): **6/6 already rendered rich help AND stopped without dispatching** — the supposedly-absent behavior was fully present. Residual value = format consistency across 6 divergent shapes → not worth ~5 lines in a compressed CLAUDE.md on a solo repo. A phantom-value addition avoided.
 - **why it matters**: [[LRN-075]] (test the UNGUIDED control) paying off one chantier later — measuring the RED before building is what caught it. For UNIVERSAL conventions the model already honors (--help, common flags, standard shapes), a "teach it to do X" instruction buys nothing but tokens; the only thing left to buy is consistency, which must clear its own ROI bar.
 - **future application**: before adding any global instruction to ELICIT a behavior, run the behavioral control first — does the model already do it unaided? If yes, the only remaining value is standardization; price it honestly vs the cost (esp. a compressed CLAUDE.md). Often: don't add it.

+## LRN-083 — Subagents are an INVALID instrument for measuring MAIN-LOOP spontaneous routing
+- **Date**: 2026-06-30
+- **pattern**: to measure whether the MAIN loop self-invokes a skill on implicit intent, dispatched subagents are non-discriminating — SUBAGENT-STOP tells them to SKIP the L1 routing mandate, and a delegated-execute framing suppresses meta-routing → they hand-do the task regardless of how strong/weak the main-loop prose is. Result pins to the no-route FLOOR (artifact, not signal). Complement of [[LRN-028]] (there subagents OVER-saw installed skills, invalidating a no-skill baseline; here they UNDER-route, invalidating a routing-measurement) — both = subagent ≠ main-loop condition.
+- **why it matters**: a 0/N subagent RED reads as "under-triggers → build the chantier" but is the [[LRN-028]] trap — the instrument can't tell strong prose from weak. Concluding from it = a pass/fail for the WRONG reason ([[LRN-074]]/[[LRN-077]]).
+- **context**: 2026-06-30 auto-skill-dispatch RED. 6 subagents on toy implicit-intent tasks → 0/6 routed → RETIRED as non-discriminating, NOT reported as a number. Reframed; measured instead in REAL fresh main-loop sessions.
+- **future application**: measure main-loop spontaneous routing/discernment in FRESH main-loop sessions (full L0–L4, no SUBAGENT-STOP, real user-turn). Observable instrument = the HUMAN typing the prompts + watching live — cron/schedule-spawned fresh sessions are the right CONDITION but UNOBSERVABLE to the orchestrator (they notify the owner, not the dispatcher), so they can't be the measurement vehicle. Never substitute a subagent for a fresh session in a routing RED. See [[LRN-028]], [[LRN-075]], [[LRN-080]].
