+# TASK-110 - Restore historical RCON-first fallback policy
+
+## Goal
+
+Correct repository defaults and documentation so historical ingestion is RCON-first, with public-scoreboard used only as a fallback when RCON fails.
+
+Keep the simplified deployment posture intact:
+
+- Live data source: `rcon`
+- Historical data source: `rcon`
+- Historical fallback: `public-scoreboard` when RCON fails
+- Elo/MMR: paused and decoupled from backend startup
+- Comunidad Hispana #03: removed from default targets
+- Comunidad Hispana #01 and #02: active in default RCON targets
+
+## Context
+
+HLL Vietnam recently simplified deployment and removed Comunidad Hispana #03 from default operational targets. The intended historical data policy has now been clarified: historical ingestion must not be disabled, and public-scoreboard must not be the normal primary historical source.
+
+The desired policy is RCON-first historical ingestion with public-scoreboard fallback when RCON fails. Documentation and defaults that currently imply "historical source is public-scoreboard" need to be corrected to "historical source is RCON-first with public-scoreboard fallback."
+
+This task is implementation-ready for branch:
+
+- `fix/historical-rcon-first-fallback-policy`
+
+## Steps
+
+1. Work on branch `fix/historical-rcon-first-fallback-policy`.
+2. Inspect the listed files before changing anything.
+3. Restore the historical default policy to RCON-first where appropriate:
+   - `HLL_BACKEND_HISTORICAL_DATA_SOURCE=rcon`
+4. Keep public-scoreboard documented and configured only as fallback, not as the normal primary historical source.
+5. Ensure `docker-compose.yml` defaults and backend example env files do not include Comunidad Hispana #03.
+6. Ensure Comunidad Hispana #01 and #02 remain in default RCON targets.
+7. Keep advanced historical workers under the advanced profile if they are already configured that way.
+8. Keep Elo/MMR paused and decoupled from backend startup.
+9. Do not delete code, migrations, persisted data, or historical ingestion modules.
+10. Update documentation and decisions to correct the historical source wording.
+11. Do not add real credentials, secrets, passwords, or local `.env` values.
+12. Run the required validation before committing.
+13. Move this task file to `ai/tasks/done/` only after validation is complete and the outcome is documented.
+14. Stage only intended files, commit, and push the branch to origin.

+- this task file moved from `ai/tasks/pending/` to `ai/tasks/done/`
+
+If additional files become necessary, explain why in the task outcome and commit message.
+
+## Expected Files Not to Modify
+
+- `frontend/**`
+- database migrations
+- persisted data
+- Elo/MMR algorithm implementation files
+- unrelated backend modules
+- local `.env`
+
+## Constraints
+
+- Do not reintroduce Comunidad Hispana #03.
+- Do not reactivate Elo/MMR.
+- Do not delete historical ingestion code.
+- Do not delete database migrations or persisted data.
+- Do not modify frontend behavior.
+- Do not add real secrets, passwords, tokens, or credentials.
+- Keep advanced historical workers under the advanced profile if already configured.
+- Keep the default Compose services limited to `backend` and `frontend`.
+- Keep the change focused on defaults, source policy, and documentation wording.
+- Do not modify unrelated files.
+- Do not leave completed work only in local; commit and push after validation.
+
+## Validation
+
+Before completing the task, run and document:
+
+- `git status`
+- `powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1`
+- `docker compose config --services`
+- `docker compose config`
+
+Also confirm and document:
+
+- default services are still only `backend` and `frontend`
+- default historical source resolves to `rcon`
+- `HLL_BACKEND_RCON_TARGETS` default includes only `comunidad-hispana-01` and `comunidad-hispana-02`
+- `comunidad-hispana-03` is not present in default RCON targets
+- documentation says public-scoreboard is fallback, not primary, for historical mode
+- no frontend files changed
+- no database migrations or persisted data changed
+- `backend/runtime/` is not created or committed
+- `git diff --name-only` matches the expected scope
+
+If integration tests are relevant and `scripts/run-integration-tests.ps1` exists, use it. If a configured test cannot be run, document the exact reason in the outcome.
+
+## Commit And Push Requirements
+
+- Run all validation before committing.
+- Run `git status`.
+- Stage only intended files.
+- Commit with a clear message, for example: `fix: restore historical rcon-first fallback policy`.
+- Push the branch to origin.
+- Do not leave completed work only in local.
+
+## Outcome
+
+Completed for branch `fix/historical-rcon-first-fallback-policy`.
+
+Validation performed:
+
+- `git status --short --branch`
+- `powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1`
+  - Passed.
+  - The script reported no product integration tests are configured for this platform-only scope.
+  - Backend startup import check passed.
+- `docker compose config --services`
+  - Passed and returned only `backend` and `frontend` for the default profile.
+- `docker compose config`
+  - Passed.
+  - The local machine had Compose environment overrides, so default policy was confirmed again with an empty env file to avoid local values.
+- `docker compose --env-file <empty-temp-file> config --services`
+  - Returned only `backend` and `frontend`.
+- `docker compose --env-file <empty-temp-file> config --format json`
+  - Confirmed `HLL_BACKEND_HISTORICAL_DATA_SOURCE=rcon`.
+  - Confirmed default `HLL_BACKEND_RCON_TARGETS` includes only `comunidad-hispana-01` and `comunidad-hispana-02`.
+  - Confirmed `comunidad-hispana-03` is not present in default RCON targets.
+- `python -c "from backend.app.config import DEFAULT_HISTORICAL_DATA_SOURCE; print(DEFAULT_HISTORICAL_DATA_SOURCE)"`
+  - Returned `rcon`.
+- `git diff --name-only`
+  - Matched the expected backend/defaults/docs scope plus `backend/app/historical_runner.py`.
+- `Test-Path backend/runtime`
+  - Returned `False`.
+
+Final source policy:
+
+- Historical ingestion defaults to RCON-first.
+- `public-scoreboard` is fallback only for historical operations where RCON fails, lacks coverage or lacks parity for the requested competitive operation.
+- Live data remains `rcon`.
+- Elo/MMR remains paused and decoupled from backend startup.
+- Comunidad Hispana #03 remains absent from default targets.
+- Comunidad Hispana #01 and #02 remain active in default RCON targets.
+
+Changed files:
+
+- `docker-compose.yml`
+- `backend/.env.example`
+- `backend/app/config.py`
+- `backend/app/historical_runner.py`
+- `README.md`
+- `backend/README.md`
+- `docs/decisions.md`
+- `ai/repo-context.md`
+- `ai/architecture-index.md`
+- this task file moved from `ai/tasks/pending/` to `ai/tasks/done/`
+
+Notable decision:
+
+- `backend/app/historical_runner.py` was updated because its default advanced historical scope still included `comunidad-hispana-03`. Leaving that default in code would contradict the task's default-target policy and the updated documentation, even though the worker remains under the advanced Compose profile.
+
+Scope confirmations:
+
+- No frontend files changed.
+- No database migrations or persisted data changed.
+- No real credentials were added; repository defaults continue to use placeholder RCON passwords.
+- `backend/runtime/` was not created or committed.
+- No follow-up task is needed for this scope.
+- The branch was pushed to origin after validation and commit.
+
+## Change Budget
+
+- Prefer fewer than 5 modified files when feasible.
+- Prefer changes under 200 lines when feasible.
+- Split follow-up work into a new task if the scope grows beyond defaults, documentation, and source-policy correction.
