fix: correcciones a PR#50 — validación schemas, credenciales, zero-variance, renombrado MASSIVE completo

[Adlgr87]

Correcciones a los bugs reportados por cubic-dev-ai en PR #50

Esta PR aplica todas las correcciones a los issues reportados por el revisor automático cubic-dev-ai, más el renombrado completo BeyondSight → MASSIVE que quedó incompleto.

🔧 Correcciones de código (5 bugs P2)

Archivo	Problema	Solución
schemas.py	strategic_weight sin validación de rango	Field(0.3, ge=0.0, le=1.0)
schemas.py	Intervention.time_start <= time_end acepta reversed	@model_validator que enforce temporal ordering
schemas.py	model_name tipo str sin restricciones	Literal[...] type con 13 nombres válidos
llm_credentials.py	os.environ mutation para credenciales	Dict en-memoria _provider_keys como store primario
state_compression.py	Zero-variance matrices → rank suboptimal	Check total_energy < 1e-12 short-circuit con rank=0

🔧 Naming canónico MASSIVE (constant pools)

Se invierte la relación de naming en empirical_config.py:

• MASSIVE_EMPIRICAL_MASTER y MASSIVE_RUNTIME_PARAMS son ahora las variables canónicas
• BEYONDSIGHT_* queda como alias backward-compatible
• Todos los consumers (empirical_calibration.py, simulator.py, forecast/engine.py, app.py, tests/) importan MASSIVE_*

🔧 Renombrado BeyondSight → MASSIVE (docs y config)

• .github/agents/my-agent.agent.md — nombre, descripción y homoglifos cirílicos corregidos
• CONTRIBUTING.md, README_ES.md, configs/multilayer.yaml, mkdocs.yml
• docs/validation/README.md + todas las plantillas + PVU_MASSIVE_EN/ES.md

📦 Archivos nuevos (PVU renombrados)

• docs/validation/PVU_MASSIVE_EN.md — copia del PVU con todo el contenido BeyondSight → MASSIVE
• docs/validation/PVU_MASSIVE_ES.md — mismo

📝 Nota sobre docs/architecture/

Los 16 documentos arquitectónicos mencionados en PR #50 (docs/architecture/) y los issues sobre massive/core/micro/ no existen en el branch actual. Quedan pendientes para cuando se complete la fusión del paquete massive/core/.

Validación

• pytest tests/test_empirical_calibration.py ✅
• pytest tests/test_empirical_integration.py ✅
• Todos los imports MASSIVE_* resueltos correctamente
• Backward compatibility: BEYONDSIGHT_* aún funciona como alias

Summary by cubic

Fixes schema and stability issues from PR #50, and makes MASSIVE naming canonical across code and docs. Credentials handling is safer and SVD handles zero-variance correctly; PVU docs added and tests updated.

• Bug Fixes

  • schemas.py: enforce strategic_weight in [0,1], validate time_start <= time_end, and restrict model_name to a fixed Literal set.
  • llm_credentials.py: store API keys in-memory (no os.environ mutation); optional env mirror for subprocesses.
  • state_compression.py: short-circuit zero-variance matrices with rank=0 to avoid unstable decompositions.

• Refactors

  • Canonicalize MASSIVE naming: MASSIVE_EMPIRICAL_MASTER and MASSIVE_RUNTIME_PARAMS are primary; BEYONDSIGHT_* kept as aliases. Updated imports in empirical_calibration.py, empirical_config.py, and tests.
  • Rename PVU docs to MASSIVE and update navigation/templates (mkdocs.yml, docs/validation/*, .github/agents/my-agent.agent.md, configs/multilayer.yaml, CONTRIBUTING.md).
  • Tests updated for MASSIVE constants; no breaking changes for existing env keys or config consumers.

^{Written for commit 9c1176f. Summary will update on new commits.}
