#![allow(dead_code)]
// One-way rules sync (Supabase → disk).
//
// Table is canonical:
//   - On startup, the on-disk global rules.md is uploaded once if the
//     table is empty for scope='global' (bootstrap, so existing content
//     isn't lost).
//   - Every poll interval, fetch all rows; if a row is newer than what
//     we last wrote, mirror it to disk.
//
// Per-project rules were removed in v0.12 — `scope` is always 'global'.
// Stale `project:*` rows are ignored (cleaned up by migration 0008).
