+# TASK-257 - Fix current match null history link crash
+
+## Goal
+
+Correct the JavaScript crash in the current match page when the optional historical link node is absent from the HTML.
+
+## Context
+
+Production showed this error on `/partida-actual.html?server=comunidad-hispana-01`:
+
+`Uncaught TypeError: can't access property "href", nodes.history is null`
+
+The crash happened before the page initialized the main current-match, kill-feed and player-stat requests, leaving the UI stuck in loading states.
+
+## Steps
+
+1. Inspect current-match HTML and JavaScript.
+2. Confirm where `nodes.history` is defined and whether the matching HTML node exists.
+3. Review similar `nodes.*` accesses for optional link or dynamically inserted nodes.
+4. Make optional link initialization null-safe without global try/catch.
+5. Validate syntax, static access patterns and current-match public endpoints.
+
+## Files to Read First
+
+- `ai/architecture-index.md`
+- `ai/repo-context.md`
+- `ai/orchestrator/frontend-senior.md`
+- `frontend/partida-actual.html`
+- `frontend/assets/js/partida-actual.js`
+
+## Expected Files to Modify
+
+- `frontend/assets/js/partida-actual.js`
+- `ai/tasks/done/TASK-257-fix-current-match-null-history-link-crash.md`
+
+## Constraints
+
+- Do not touch backend, scheduler, RCON, server config or port `27001`.
+- Do not touch TeamKills behavior.
+- Do not reactivate Elo/MMR.
+- Do not reintroduce Comunidad Hispana #03.
+- Do not touch physical assets, maps, weapons, clans or brands.
+- Do not touch `ai/system-metrics.md`.
+- Do not include `tmp/`, `TASK-204` or unrelated previous changes.
+- Do not commit or push.
+
+## Validation
+
+- `node --check frontend/assets/js/partida-actual.js` passed.
+- Static search confirmed there are no direct `nodes.history.href`, `nodes.scoreboard.href` or `nodes.scoreboard.hidden` patterns left outside null-safe helpers.
+- DOM simulation with `current-match-history` absent completed without TypeError and reached controlled current-match, kill-feed and player-stat states.
+- Chrome headless validation of `/partida-actual.html?server=comunidad-hispana-01` from a local static frontend server reported `uncaughtExceptionCount: 0` and `typeErrorCount: 0`. With no local backend running, the page reached controlled empty/error states instead of blocking in loading text.
+- Public audit command executed:
+  `python .\scripts\audit_public_requests.py --base-url https://comunidadhll.devzamode.es --timeout 30 --output tmp\task257_full_audit_after.json`
+- Audit summary: `CRITICAL: 0`.
+- Required current-match endpoints returned `OK 200`:
+  `current-match-comunidad-hispana-01`,
+  `current-match-comunidad-hispana-02`,
+  `current-match-kills-comunidad-hispana-01`,
+  `current-match-kills-comunidad-hispana-02`,
+  `current-match-players-comunidad-hispana-01`,
+  `current-match-players-comunidad-hispana-02`.
+
+## Outcome
+
+`nodes.history` pointed to `#current-match-history`, but `frontend/partida-actual.html` no longer contains that element. The node was removed from the current page markup in `d6f1739 Adjust countdown and page navigation`; only the top navigation historical link remains.
+
+The fix makes optional link handling null-safe through dedicated helpers. If the history or scoreboard nodes exist, their attributes are updated. If they do not exist, initialization continues and the main data loaders still run.
+
+Dynamic feed and player-stat containers are also guarded before rendering so missing optional/dynamic nodes do not cascade into TypeError failures.
+
+No backend, endpoint, scheduler, RCON, server configuration, assets, maps, weapons, clans, brands, TeamKills, Elo/MMR, Comunidad Hispana #03 or `ai/system-metrics.md` changes were made by this task.
