description: "Genera proposals automaticas para registry.db.proposals a partir de telemetria de call_monitor.operations.db. Aplica 4 reglas MVP: copy_detected, orphan, bug, wrapper_skip. IDs deterministas (sha1 truncado) garantizan idempotencia. Cierra la fase MEJORAR del bucle reactivo. Issue 0085h."

notes: |
  Reglas MVP implementadas:

  | Regla | Threshold | Proposal |
  |---|---|---|
  | copy_detected | match en copied_code | improve_function (target = registry_id matched) |
  | orphan | calls_90d=0 AND writes_count=0 AND no upstream consumer | deprecate_function |
  | bug | error_rate>0.1 AND calls_total>3 | improve_function |
  | wrapper_skip | violations.function_id COUNT > 3 | improve_function |

  Reglas pendientes (sin data aun):
  - perf_regression: requiere p95 (no almacenado todavia).
  - test_flaky: requiere test_runs poblado.
  - e2e_blast_radius: requiere e2e_runs_fn poblado.
  - pattern_inline: requiere patterns clustering (0085f).

  Idempotencia: cada proposal tiene `id = auto_{rule}_{sha1-10}` deterministico
  sobre (rule_id, target_id, extra). PersistProposalDrafts usa INSERT OR IGNORE
  para no sobreescribir proposals ya revisadas (approved/rejected).

  created_by='reactive_loop' para distinguir de proposals manuales.

  Filtrado orphan: cruza con `uses_functions` JSON arrays de functions/apps/
  analysis. Si alguien declara la funcion como dependencia, no se marca orfana
  aunque tenga calls_90d=0 (uso intencional, no instrumentado por telemetria).
