From 6ab887a024223d6922391a6c882505fb01e49eec Mon Sep 17 00:00:00 2001 From: santisoutoo Date: Fri, 24 Jul 2026 14:37:00 +0200 Subject: [PATCH 1/8] feat(bench): procedure-compliance metric and pure scorer (#85) scoring.py turns a recorded trajectory into a ScoreCard with no Sim, no network, no compiled binding: the vector (coverage, order, end_state, safety, extraneous) is always reported and the derived scalar (safety x tidiness x (0.4 end_state + 0.4 coverage + 0.2 order), order weight redistributed when null) is for rankings only. Safety is a gate, not a trade-off: one dangerous forbidden action floors the scalar to 0. Only command actions score; reads, failed commands and off-surface attempts are reported but never scored. Matching is a deterministic canonical assignment (injective, multiplicity counts) that classifies every effective command as matched_required / optional / forbidden / extraneous, kept in the ScoreCard detail. docs/fase5-metrica.md is the full spec (matching, every component, the edge-case table, the contamination section) and D-026 records the shape decision. Refactor: parse_ground_truth/parse_success extracted from load_scenario so the scorer parses the embedded ground truth through the same path that validated it. Lazy exports keep the scorer binding-free. 21 synthetic tests, one per edge case, plus the import-without-binding guard and the acceptance-case strict ordering (full 1.00 > omitted 0.90 > ext-pwr-only 0.55 > nothing 0.00 -- the real smoke finding). 77 green.

El recall no explica esa omisión; la ejecución bajo observación, sí. +2. **Canarios naturales**: las divergencias documentadas FBW-vs-real (los `source.notes` de cada escenario, la distinción `EcamSource` de D-014) hacen de detector — un agente que ejecute el QRH verbatim donde el modelo diverge delata recall sobre observación; se reporta cualitativamente. +3. **Mitigación futura** (no de esta etapa): el eje de ablación "QRH access vs not" ya previsto en #20, y el reporte por componentes en vez de por pass-rate (el vector ya lo impone).

First scenario to exercise the scorer's mild severity. blue_epump_overheat: pure containment — isolate the pump and accept the loss of blue (inconsequential parked). Both overheat cautions LATCH (they do not retire on pb-off, as on the real aircraft), so success is state-based (pump commanded off + pressures where achievable + engines running), no ecam_clear_of. The green reservoir leak was probed as a sibling and DISCARDED (documented in the yellow scenario's source.notes): its PTU cross-compensation cascades into yellow, leaving no bounded stable state — a fidelity boundary, not a scenario. Scripted procedure + ignore tests for both; 59 green.

Three spots that raised a bare KeyError/ValueError now raise a named ScoringError that says what is malformed: - a successful set_control (is_error=false) whose args lack a 'control' or carry a non-numeric 'value'; - a run whose meta.scenario has no ground_truth (names the run_id). _end_state also tolerates a null final_state/ecam_clear_of list, and a null meta.scenario no longer trips the id lookup. ScoringError is exported for parity with ScenarioError so slice G can skip corrupt files. Corruption stays as loud as read_trajectory: never a silent wrong number. New tests cover each malformed shape plus the previously untested defensible edges (empty procedure, forbidden/optional overlap, ecam-only success_eval, asdict round-trip of the nested CommandClass).

The narrow `import a320_bench.cli_score` check passed and hid it. Both imports are now deferred into the run/serve paths that need them, mirroring the existing lazy-litellm pattern; the score dispatch touches neither. _collect now collapses overlapping arguments (a file passed twice, or a directory plus a file inside it) by resolved path, so a run is never double-counted into the aggregate means. Added type hints to the CLI's public helpers. Tests: a binding-free score-dispatch regression (a320_sim/litellm blocked in sys.modules), path dedupe, good-file + empty-dir -> exit 0, and a truncated/incomplete run serializing as JSON null. 98 green.

El objetivo no es la autopsia sino la **re **Qué pasó**: al plantear la Fase 3 se presentó como trampa técnica que FastMCP ejecutaría los tools **síncronos en un hilo** (`anyio.to_thread`) y que eso chocaría con el `unsendable` del binding (D-010), recomendando escribirlos `async def` para evitarlo. Al leer el SDK, lo cierto es lo contrario: `func_metadata.py` los llama **inline en el hilo del event loop** (`if fn_is_async: return await fn(...)` / `else: return fn(...)`), sin `to_thread` ni executor. La recomendación era innecesaria y la trampa real es la **inversa**: el peligro es que alguien *añada* `to_thread` para no bloquear el event loop. Se detectó antes de escribir código, pero la afirmación ya había ido a una recomendación sobre la que se decidió el siguiente paso. **Causa raíz**: afirmar de memoria el comportamiento interno de una dependencia que no se había leído, y presentarlo con el **mismo nivel de confianza** que los hallazgos sí verificados. El proyecto ya tiene la norma de citar `archivo:línea` del vendor de FBW para cualquier afirmación sobre su lógica (D-005, D-012, D-014 son eso); esa norma no se aplicó a una dependencia externa. **Regla**: antes de escribir en un plan, una decisión o un doc cómo se comporta una dependencia por dentro (threading, defaults, firmas, versiones), **leer su código o su doc de la versión que vamos a fijar y citar `archivo:línea`** — el mismo estándar que se le exige al vendor. Lo no verificado se marca como "a verificar", no se afirma. Aplica igual a la versión: comprobar en PyPI/upstream cuál es la estable antes de asumir una API (la 2.0 de `mcp` ya usa otra). + +### L-006 — Un contrato "sin binding / sin red / sin extra" se verifica por el entry point real, no por el módulo hoja +**Fecha**: 2026-07-24 (Fase 5, slice G, #86; cazado en review, no llegó a `main`) +**Qué pasó**: `a320-bench score` se anunciaba binding-free (el revisor del paper puntúa con `pip install -e bench/` a secas, sin `a320_sim` compilado), pero `cli.py` importaba `from a320_bench.episode import run_episode` a nivel de módulo, y `episode.py` hace `import a320_sim`. El entry point es `a320_bench.cli:main`, así que ejecutar `a320-bench score` arrancaba importando `cli` → `episode` → `a320_sim` y reventaba con `ModuleNotFoundError` antes de despachar nada. El test lo comprobaba importando el módulo hoja (`import a320_bench.cli_score`, que sí es limpio) en vez del entry point, así que el criterio del slice quedó roto sin que ningún test lo viera. +**Causa raíz**: verificar una propiedad de import (sin binding) por el submódulo aislado, no por el punto de entrada que el usuario ejecuta; un import de módulo-top en un dispatcher compartido arrastra las dependencias de ramas que ese comando no usa. +**Regla**: para cualquier propiedad "sin binding / sin red / sin extra opcional", el test la ejerce **por el entry point público** (`cli:main`) con la dependencia **bloqueada en `sys.modules`** (`monkeypatch.setitem(sys.modules, "a320_sim", None)`), no importando el módulo hoja. Los imports que arrastran binding/opcionales van **lazy dentro de la rama que los usa** (el patrón que ya usaba `litellm`), nunca en el módulo-top de un dispatcher compartido.
