+# UCEPSA — Semántica del resumen de paros Shop Floor v0.3.4.1
+
+## Hallazgo
+
+La validación de v0.3.4 mostró para el workorder 340:
+
+```text
+physical_stop_count = 31
+eligible_stop_count = 28
+eligible_stop_minutes = 55,25
+```
+
+El diagnóstico descomponía esos 55 minutos en:
+
+```text
+CANDIDATE_GROUP       32,88 min
+CANDIDATE_INDIVIDUAL  17,51 min
+EXCLUDED_NOISE         0,11 min
+OPEN_MONITORING        4,81 min
+```
+
+La vista de resumen sumaba todos los minutos observados en la columna
+`eligible_stop_minutes`, aunque el importe económico sí excluía correctamente
+el ruido y el paro abierto.
+
+## Corrección
+
+`eligible_stop_minutes` pasa a incluir únicamente filas con:
+
+```text
+technically_eligible = true
+```
+
+Se añaden columnas separadas:
+
+- `observed_stop_minutes`
+- `telemetry_covered_stop_minutes`
+- `candidate_group_minutes`
+- `candidate_individual_minutes`
+- `excluded_noise_minutes`
+- `open_monitoring_minutes`
+- `blocked_minutes`
+
+No se modifica la vista de candidatos, la cola SHADOW, la cola oficial ni los
+datos raw.
+
+## Resultado esperado para la sesión 340
+
+A la hora de la validación inicial, aproximadamente:
+
+```text
+observed_stop_minutes      55,3
+eligible_stop_minutes      50,4
+candidate_group_minutes    32,9
+candidate_individual       17,5
+excluded_noise              0,1
+open_monitoring             4,8
+shadow_capacity_loss_eur   30,2
+```
+
+El paro abierto puede seguir creciendo hasta que la máquina vuelva a arrancar,
+por lo que los valores exactos pueden variar.
+
+## Despliegue
+
+No es necesario detener servicios.
+
+```bash
+FILE=/srv/mesavault/40-clients/ucepsa/edge-oee-demo/sql/versions/107_fix_shopfloor_stop_summary_semantics_v0341.sql
+
+docker exec -i mv_ucepsa_postgres_hot sh -lc \
+  'psql -v ON_ERROR_STOP=1 -U "$POSTGRES_USER" -d "$POSTGRES_DB"' \

+
+## Validación
+
+```bash

+docker exec -i mv_ucepsa_postgres_hot sh -lc \
+  'psql -v ON_ERROR_STOP=1 -U "$POSTGRES_USER" -d "$POSTGRES_DB"' \
+  < "$VALIDATION"
+```
+
+Valores obligatorios:
+
+```text
+eligible_decomposition_errors = 0
+summary_candidate_mismatches = 0
+open_or_noise_inflation_errors = 0
+official_summary_rows = 0
+official_operator_queue_rows = 0
+```
