Looks good to me too! 👍 But why there are so many unrelated commits in the branch? For example: |

github is usually getting confused when changing the target branch, but the diff is clean and the merge commit should be clean as well |

#10917) Implements persistent storage for the experimental collator protocol's reputation database. Changes: - Adds `PersistentDb` wrapper that persists the in-memory reputation DB to disk - Periodic persistence every 10 minutes (30s in test mode) - Immediate persistence on slashes and parachain deregistration - Loads existing state on startup with lookback for missed blocks Implementation: `PersistentDb` wraps the existing `Db` and adds persistence on top: - All reputation logic (scoring, decay, LRU) stays in `Db` - Persistence layer handles disk I/O and serialization - Per-para data stored in parachains_db Tests: - `basic_persistence.rs`: Validates persistence across restarts and startup lookback - `pruning.rs`: Validates automatic cleanup on parachain deregistration --------- Signed-off-by: Alexandru Cihodaru <alexandru.cihodaru@parity.io> Co-authored-by: alindima <alin@parity.io> Co-authored-by: Tsvetomir Dimitrov <tsvetomir@parity.io> Co-authored-by: Serban Iorga <serban@parity.io> Co-authored-by: Serban Iorga <serban300@gmail.com> Co-authored-by: cmd[bot] <41898282+github-actions[bot]@users.noreply.github.com> (cherry picked from commit 744acf5)
