+# TASK-152 - Current match live kill feed
+
+## Goal
+
+Expose recent current-match kill events and render them as a live visual feed
+on `partida-actual.html`.
+
+## Background
+
+The current-match page will exist at
+`partida-actual.html?server=<server_slug>`. The backend already stores/parses
+RCON AdminLog data and materializes kill/player stats for historical matches.
+
+Existing materialization logic uses AdminLog kill payload fields such as:
+
+- `killer_id`
+- `killer_name`
+- `killer_team`
+- `victim_id`
+- `victim_name`
+- `victim_team`
+- `weapon`
+
+We now want a live/current-match kill feed similar to a FPS kill feed: killer,
+weapon, victim, teamkill distinction, timestamp.
+
+## Constraints / DO NOT BREAK
+
+- Do not query RCON directly from the frontend.
+- Do not expose raw AdminLog lines.
+- Do not expose admin-only/sensitive fields.
+- Do not break existing historical materialization.
+- Do not break existing match detail player stats.
+- Do not depend on server #03.
+- Do not fabricate kill events.
+- Do not duplicate kill rows on repeated polling.
+- Keep polling safe.
+
+## Allowed Changes
+
+- backend endpoint for current match kill feed
+- backend read-model/helper for current/open match event window
+- frontend current-match JS/CSS
+- tests for event normalization/filtering where practical
+
+## Implementation Requirements
+
+1. Add a backend endpoint for recent current-match kill events by server.
+2. Supported servers:
+   - `comunidad-hispana-01`
+   - `comunidad-hispana-02`
+3. Unknown server values must return a safe 400/404 style response and must
+   not query arbitrary targets.
+4. The endpoint should return normalized event rows:
+   - `event_id`
+   - `event_timestamp` or `server_time`
+   - `killer_name`
+   - `killer_team`
+   - `victim_name`
+   - `victim_team`
+   - `weapon`
+   - `is_teamkill`
+   - confidence/source if needed
+5. The endpoint should only return events belonging to the current/open match
+   if that can be determined.
+6. If the current/open match window cannot be determined reliably, return a
+   safe recent window and include a clear confidence marker, for example:
+   - scope: `"recent-admin-log-window"`
+   - confidence: `"partial"`
+7. Do not return raw AdminLog text.
+8. Add frontend rendering for a kill feed:
+   - newest events visible at top or bottom consistently
+   - killer name
+   - weapon label/icon placeholder
+   - victim name
+   - timestamp
+   - teamkill visual distinction
+9. Prevent duplicate rendering:
+   - track `event_id` values already rendered
+   - update existing rows only if needed
+10. Poll every 15-30 seconds.
+11. Add an empty state:
+    - "Todavía no se han detectado bajas en esta partida."
+12. Add an error/stale state:
+    - "No se pudo actualizar el feed de combate."
+13. Do not show fake/sample kill events in production UI.
+
+## Files to Read First
+
+- `AGENTS.md`
+- `ai/architecture-index.md`
+- `ai/repo-context.md`
+- `ai/orchestrator/backend-senior.md`
+- current-match page files created by TASK-151
+- AdminLog materialization/read-model files that already normalize kill data
+
+## Expected Files to Modify
+
+- backend current-match kill feed endpoint/read-model files
+- current-match frontend JS/CSS files
+- focused tests for event normalization/filtering where practical
+
+## Validation
+
+- `python -m compileall backend/app`
+- Run backend tests related to AdminLog/materialization/current-match feed.
+- Run `node --check` on current-match frontend JS.
+- Review `git diff --name-only` and confirm the changed files match this task.
+
+## Manual Verification
+
+1. Open `partida-actual.html?server=comunidad-hispana-01`.
+2. Open `partida-actual.html?server=comunidad-hispana-02`.
+3. Verify kill feed renders only normalized events.
+4. Verify repeated polling does not duplicate rows.
+5. Verify teamkills are visually distinguishable.
+6. Verify raw AdminLog lines are never displayed.
+
+## Commit Message
+
+`feat: add current match live kill feed`
+
+## Expected Outcome
+
+The current-match page can show a safe, normalized, non-duplicated live kill
+feed based on RCON/AdminLog data.
+
+## Outcome
+
+Document the feed scope and confidence behavior, event normalization choices,
+polling validation, and any follow-up task instead of expanding scope.
+
+## Change Budget
+
+- Prefer fewer than 5 modified files.
+- Prefer changes under 200 lines when feasible.
+- Split the work into follow-up tasks if the scope grows.
