# Poller Upgrade Plan

**Status:** Not yet implemented.

## Goal
Remove the poller's direct dependency on `SQLiteClusterStore._conn()` and replace it with a public store method.

## Current Problem
- `news_mcp/jobs/poller.py:173` clears legacy `feed_state` rows with `with store._conn() as conn:`.
- That couples the refresh loop to a private SQLite implementation detail.
- Test doubles need to expose `_conn()`.

## Proposed Refactor
1. Add a public `clear_legacy_feed_state()` method to `SQLiteClusterStore`.
2. Move the `DELETE FROM feed_state WHERE feed_key LIKE 'newsfeeds:%'` logic into that method.
3. Update `poller.py` to call the public method.
4. Adjust tests accordingly.

## Rules
- Keep the change narrow.
- Do not alter feed-hash or clustering behavior in the same patch.
- Preserve current legacy-row cleanup behavior exactly.
