+# TASK-144 - Home region cleanup and RCON freshness diagnostics
+
+## Goal
+
+Hide placeholder region values on the home page server cards and improve RCON historical freshness diagnostics so stale recent matches are explainable from worker/runner logs.
+
+## Context
+
+The home page currently renders `Region pendiente` when a server region is missing. Recent RCON materialized matches can also appear stale without clear logs showing whether AdminLog events were seen, inserted, duplicated or materialized.
+
+## Steps
+
+1. Inspect home server-card rendering and RCON runner/worker/ingestion/materialization paths.
+2. Hide placeholder/missing region quick facts while preserving map data.
+3. Determine whether historical-runner refreshes RCON AdminLog materialization or whether rcon-historical-worker owns it.
+4. Add minimal logging/summary output for AdminLog ingestion/materialization and latest materialized match freshness.
+5. Validate frontend syntax, backend compile, pipeline scripts, Compose services, logs, manual commands and rendered pages.

+
+## Outcome
+
+Implemented. Home server cards now omit the Region quick fact when the region is missing or a placeholder such as `Region pendiente`, while preserving the Mapa quick fact. RCON capture now runs AdminLog materialization after AdminLog ingestion and emits freshness diagnostics in the worker result, including event counters, materialized match counters and latest materialized/AdminLog match-end timestamps per configured server.
+
+Findings:
+
+- `historical-runner` already calls the RCON capture path when historical data source is RCON, but the capture path previously ingested AdminLog entries without materializing them into recent matches.
+- `rcon-historical-worker` owns the 10-minute capture loop and now materializes after ingestion, so recent matches can advance without requiring a manual materialization command.
+- The live diagnostics show new recent data after the previously stale `17:38` item. Recent matches now include `comunidad-hispana-01:1779299747:1779305147:carentanwarfare` closed at `2026-05-20T19:26:46.519Z` and `comunidad-hispana-02:1779296626:1779301626:carentanwarfare` closed at `2026-05-20T18:41:59.219Z`.

+Notes:

+- The RCON pipeline script reports existing SQLite `ResourceWarning` messages from its test harness, but the unittest suites return `OK` and the script reports validation passed.
+- The integration script exits successfully, but the local runtime DB emits an existing `database disk image is malformed` traceback after the pass message. Runtime DB files were not modified for commit.
+- Browser plugin runtime tools were not exposed by tool discovery in this session, so rendered validation used local Chrome/Selenium fallback.

+# TASK-POSTGRES-RCON-PHASE-1 - Migrate RCON historical persistence phase 1
+
+## Goal
+
+Move the lock-prone RCON historical pipeline to PostgreSQL in Docker while
+keeping local SQLite fallback and fixing the requested match-detail and server
+card frontend regressions.
+
+## Context
+
+AdminLog ingestion and materialization currently share SQLite files with
+multiple services and materialization can fail with `database is locked`.
+PostgreSQL must become authoritative for RCON capture, AdminLog events,
+materialized matches, player stats and the detail/recent read model in the
+advanced Docker flow. Scoreboard historical persistence may remain on SQLite in
+this phase when it is used only as fallback or correlation source.
+
+## Steps
+
+1. Inspect the storage, read-model and frontend files named in the request.
+2. Add a deterministic PostgreSQL schema and route the phase-1 RCON storage
+   domains through it when `HLL_BACKEND_DATABASE_URL` is set.
+3. Wire Compose diagnostics and required frontend fixes without expanding Elo,
+   backend scope outside RCON persistence, or Comunidad Hispana #03 targets.
+4. Validate the requested commands, document what remains SQLite-backed, and
+   complete the task record.

+- `docs/decisions.md`

+
+## Constraints
+
+- PostgreSQL is the Docker default for migrated RCON domains.
+- SQLite remains only fallback or source material for domains not migrated in
+  this phase.
+- Do not add SQLite lock workarounds as the main solution.
+- Keep external scoreboard URLs on the trusted scoreboard allowlist.
+- Do not modify unrelated files or add runtime database artifacts.
+
+## Validation

+- `python -m app.storage_diagnostics`

+- `powershell -ExecutionPolicy Bypass -File scripts/run-rcon-data-pipeline-tests.ps1`
+- `powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1`
+- Requested Docker Compose and endpoint checks when local Docker/RCON
+  credentials permit them.
+
+## Outcome
+
+Implemented phase-1 PostgreSQL delegation for RCON capture samples/windows,
+AdminLog events/profile snapshots, materialized RCON matches/player stats, and
+safe scoreboard candidate caching. Docker Compose now configures PostgreSQL as
+the RCON storage backend for `backend`, `historical-runner` and
+`rcon-historical-worker`; local code paths with explicit SQLite paths or no
+database URL retain SQLite fallback behavior.
+
+Frontend changes remove hover-driven player panel expansion in the internal
+match detail table, keep the scoreboard link on the internal detail action area
+only, and suppress pending-style region placeholders on server cards.
+
+Validation completed:
+
+- `python -m compileall backend/app`
+- `python -m app.storage_diagnostics` from `backend/`
+- `node --check frontend/assets/js/main.js`
+- `node --check frontend/assets/js/historico.js`
+- `node --check frontend/assets/js/historico-recent-live.js`
+- `node --check frontend/assets/js/historico-partida.js`
+- `powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1`
+- `docker compose --profile advanced config --quiet`
+- local fallback HTTP smoke for `/health`,
+  `/api/historical/recent-matches`, and the requested known match detail URL
+- direct known-match detail payload check confirmed safe URL
+  `https://scoreboard.comunidadhll.es:5443/games/1562094`
+
+`scripts/run-rcon-data-pipeline-tests.ps1` completed parser/storage and
+unittest work, then exited nonzero when its optional Docker smoke step could
+not reach the Docker Desktop Linux engine. The requested `docker compose
+--profile advanced up ...` and `docker compose --profile advanced ps` checks
+failed for the same local engine-unavailable reason, so container diagnostics,
+container RCON commands and Docker-backed HTTP probes remain to rerun when
+Docker is available. The Browser plugin is listed but its required JavaScript
+control tool was not exposed in this session, so rendered interaction QA remains
+manual or follow-up Browser verification.
+
+Phase boundary documented in `docs/decisions.md` and diagnostics: live server
+snapshot cache, public-scoreboard `historical_*` data/rankings, historical
+snapshot files, player-event ledger and paused Elo/MMR storage remain SQLite or
+file-backed in this phase.
+
+## Change Budget
+
+This phase intentionally exceeds the default change budget because PostgreSQL
+wiring crosses schema initialization, Compose runtime, RCON storage domains,
+diagnostics, docs, and the requested frontend regressions. Keep the migration
+surface limited to the RCON path and leave remaining SQLite domains documented.

+## Decision 017: PostgreSQL phase 1 for RCON historical persistence
+
+La primera migracion de persistencia a PostgreSQL cubre el camino que sufria
+contencion SQLite entre `backend`, `historical-runner` y
+`rcon-historical-worker`:
+
+- captura prospectiva RCON, muestras y ventanas competitivas
+- eventos AdminLog deduplicados y snapshots de perfil derivados
+- partidas RCON materializadas y estadisticas por jugador
+- candidatos confiables de URL de scoreboard que puedan poblarse para
+  correlacion de detalle
+
+Docker Compose configura `HLL_BACKEND_DATABASE_URL` y usa PostgreSQL como
+backend autoritativo para esas tablas. La ejecucion local sin esa variable sigue
+usando SQLite como fallback temporal para preservar comandos y tests locales.
+
+Quedan SQLite-backed en esta fase porque no forman parte del lock-prone writer
+path migrado y siguen cubriendo fallback publico o caches locales:
+
+- snapshots live y cache de `/api/servers`
+- tablas `historical_*` de scoreboard publico, rankings y correlacion legacy
+- snapshots historicos precalculados, ledger player-event y Elo/MMR pausado
+
+La correlacion de URL publica en detalle usa primero candidatos PostgreSQL
+confiables cuando existan y puede seguir leyendo filas `historical_*`
+persistidas en SQLite durante la transicion. El diagnostico operativo se expone
+con `python -m app.storage_diagnostics`.
