+# TASK-253 - Polish player profile KPM, links and labels
+
+## Summary
+
+This task improves the public player profile in `stats.html` without changing the validated historical match-detail KPM model.
+
+Changes included:
+
+- real weekly/monthly profile KPM when safe
+- no visible raw player ID in the personal profile card or profile heading
+- translated `current-week` / `current-month` labels
+- external profile buttons aligned with `historico-partida`
+
+Teamkills were not changed here. TASK-251 remains the reference audit for that problem.
+
+## Files Read First
+
+- `frontend/stats.html`
+- `frontend/assets/js/stats.js`
+- `frontend/assets/js/historico-partida.js`
+- `backend/app/payloads.py`
+- `backend/app/rcon_historical_player_stats.py`
+- `docs/HISTORICAL_MATCH_KILLS_PER_MINUTE_ANALYSIS.md`
+
+## Real KPM Decision
+
+The player profile does not use match duration and does not reuse `kills_per_match`.
+
+It now exposes real KPM only when the selected weekly or monthly window can aggregate player facts with:
+
+- `active_time_source = connection_intervals`
+- `active_time_source = connection_intervals_carryover`
+- `player_active_seconds >= HLL_KPM_MIN_ACTIVE_SECONDS`
+
+Formula:
+
+```text
+sum(eligible_kills) / (sum(eligible_player_active_seconds) / 60)
+```
+
+If the profile window has:
+
+- no active time -> `kpm_status = missing_active_time`
+- only fallback spans without reliable connection intervals -> `kpm_status = missing_connection_intervals`
+- real connection rows but below threshold -> `kpm_status = insufficient_active_time`
+
+Only `kpm_status = ready` is rendered in the frontend.
+
+## Backend Notes
+
+`build_stats_player_profile_payload(...)` now exposes:
+
+- `platform`
+- `steam_id_64`
+- `epic_id`
+- `external_profile_links`
+- `player_active_seconds`
+- `player_active_minutes`
+- `kpm`
+- `kpm_status`
+- `active_time_source`
+- `active_time_coverage`
+
+If `player_period_stats` is unavailable for the requested weekly/monthly profile, the endpoint now falls back to runtime aggregation for that single player and window instead of returning an empty read-model-only payload.
+
+This keeps the route useful without touching scheduler or snapshot policies.
+
+## Frontend Notes
+
+Profile polish in `stats.js`:
+
+- removed visible `ID:` from the identity card
+- removed raw player ID from the visible profile heading/state
+- translated:
+  - `current-week` -> `Semana actual`
+  - `current-month` -> `Mes actual`
+  - fallback labels for previous windows
+- added external profile buttons using the same destinations as `historico-partida`
+- keeps defensive image `onerror`
+- renders KPM only when `kpm_status == ready`
+
+Profile buttons by platform:
+
+- Steam:
+  - Steam
+  - Hellor
+  - HLL Records
+  - Helo
+- Epic:
+  - Hellor
+  - HLL Records
+
+## Teamkills Note
+
+No teamkills fix was implemented here.
+
+Reference:
+
+- `TASK-251-investigate-teamkills-ranking-zeroes.md`
+
+Observed state remains:
+
+- `rcon_match_player_stats.teamkills` stays at zero in the audited dataset
+- same-team kill events were not present in the audited AdminLog dataset
+- lifetime profile snapshots can show TK counters, but they are not a valid direct source for annual ranking without redesign/backfill
+
+## Validation
+
+Executed:
+
+- `node --check frontend/assets/js/stats.js`
+- `python -m compileall backend/app`
+- `cd backend; python -m unittest tests.test_current_match_payload`
+- `cd backend; python -m unittest tests.test_historical_snapshot_refresh`
+- `cd backend; python -m unittest tests.test_stats_player_profile_payload`
+
+Static checks:
+
+- no visible `ID:` remains in the personal profile card
+- `current-week` / `current-month` no longer remain as visible UI labels
+- external profile buttons do not print raw IDs on screen
+- KPM is rendered only for `kpm_status == ready`
+
+## Notes
+
+- No scheduler changes.
+- No RCON or server configuration changes.
+- No asset changes were required.

 - rows that only expose `event_span_fallback`
 
+## Personal Player Profile
+
+The public player profile in `stats.html` can now expose real KPM for the selected weekly or monthly window when the profile endpoint can aggregate:
+
+- `SUM(player_active_seconds)`
+- only over rows with:
+  - `active_time_source = connection_intervals`
+  - `active_time_source = connection_intervals_carryover`
+  - `player_active_seconds >= HLL_KPM_MIN_ACTIVE_SECONDS`
+
+Weekly and monthly profile KPM use:
+
+```text
+sum(eligible_kills) / (sum(eligible_player_active_seconds) / 60)
+```
+
+This is intentionally narrower than the window total:
+
+- profile `kills` still show all kills in the selected window
+- profile `KPM` only becomes `ready` when the active-time subset is reliable enough
+
+The profile payload now exposes:
+
+- `player_active_seconds`
+- `player_active_minutes`
+- `kpm`
+- `kpm_status`
+- `active_time_source`
+- `active_time_coverage`
+
+If the profile read model is empty, the endpoint can safely fall back to runtime aggregation over `rcon_match_player_stats` for that single player and time window. This avoids inventing KPM while keeping the page usable before the read model is refreshed.
+
 ## Kills Per Match Labels
 
 Several public tables were showing `kills_per_match` under the visible label `KPM`.
