TASK-171 - Validate Stats section with backend real data

Goal

Validate the Stats section end-to-end against local backend and data sources without introducing new features.

Context

The previous tasks already implemented player search, player profile, annual ranking endpoint, and the Stats frontend page.

Maintain the current product identity: Spanish-speaking HLL Vietnam community, military/Vietnam/tactical/sober visual direction and controlled repository evolution.

Steps

1. Confirm git status before starting validation and verify pre-existing local frontend files.
2. Read required files first (AGENTS + docs + frontend/backend files for Stats).
3. Validate backend endpoints when available:
   • GET /health
   • GET /api/stats/players/search?q=
   • GET /api/stats/players/{player_id}
   • GET /api/stats/rankings/annual?year=&server_id=all&metric=kills&limit=20
4. Serve or open frontend/stats.html and validate UI states.
5. Run required checks:
   • node --check frontend/assets/js/stats.js
   • powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1 (if applicable)
6. Record validation results and keep any changes within minimal scope.
7. If a small Stats-specific bug is found, patch it.

Files to Read First

• AGENTS.md
• ai/repo-context.md
• ai/architecture-index.md
• docs/stats-section-functional-plan.md
• frontend/stats.html
• frontend/assets/js/stats.js
• backend/app/routes.py
• backend/app/rcon_historical_player_stats.py
• backend/app/rcon_historical_leaderboards.py
• backend/app/rcon_annual_rankings.py

Expected Files to Modify

• ai/tasks/done/TASK-171-validate-stats-section-with-backend-data.md
• (Optional) frontend/assets/js/stats.js or frontend/stats.html only for minimal Stats-specific bug fixes.

Constraints

• No new features.
• No visual redesign.
• Do not touch frontend/assets/js/partida-actual.js.
• Do not touch frontend/assets/img/clans/bxb.png.
• Do not reactivate Elo/MMR.
• Do not reintroduce Comunidad Hispana #03.
• Do not modify historical workers.
• Do not modify DB unless a migration follow-up is explicitly required.

Validation

Before completing, ensure:

• backend endpoints were tested where possible.
• frontend runtime states were checked.
• node --check frontend/assets/js/stats.js.
• scripts/run-integration-tests.ps1 executed when available.
• git diff --name-only checked if modifications were made.

Outcome

Status: completed

Files read

• AGENTS.md
• ai/repo-context.md
• ai/architecture-index.md
• docs/stats-section-functional-plan.md
• frontend/stats.html
• frontend/assets/js/stats.js
• backend/app/routes.py
• backend/app/rcon_historical_player_stats.py
• backend/app/rcon_historical_leaderboards.py
• backend/app/rcon_annual_rankings.py

Endpoints probados

• GET /health -> 200
• GET /api/stats/players/search?q=rambo -> 200 (items empty)
• GET /api/stats/players/76561198350628987?timeframe=weekly -> 200
• GET /api/stats/rankings/annual?year=2026&server_id=all&metric=kills&limit=20 -> 200, snapshot_status="ready"
• GET /api/stats/rankings/annual?year=1990&server_id=all&metric=kills&limit=3 -> 200, ready and empty
• GET /api/stats/rankings/annual?year=2040&server_id=all&metric=kills&limit=20 -> 200, snapshot_status="missing", items=[]
• GET /api/stats/rankings/annual?year=2026&metric=deaths&limit=20 -> 400 (Invalid metric parameter)

Respuestas y estado visual

• Health and payload endpoints responded correctly.
• Search can return empty set with local dataset.
• Player profile endpoint returns weekly/monthly ranking payloads and allows runtime rendering.
• Annual ranking endpoint returns ready/empty and missing states as expected.
• frontend/stats.html and frontend/assets/js/stats.js were served with HTTP 200.
• node --check frontend/assets/js/stats.js passed.
• Browser interactive runtime error checks could not be executed in this environment.

Validaciones ejecutadas

• node --check frontend/assets/js/stats.js
• powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1
• local backend started and queried via endpoints
• local static server started and stats.html / stats.js fetched successfully

Validaciones pendientes / limitaciones

• No se dispuso de DB con jugadores de prueba para validar search con resultados positivos y render completo en UI.
• No se hizo comprobacion interactiva de "backend no disponible" en navegador real.

Archivos modificados

• ai/tasks/in-progress/TASK-171-validate-stats-section-with-backend-data.md

Siguiente task recomendada

• Añadir smoke test de UI con navegador/headless para validar estados runtime de stats.js y errores de backend en integración local.
