Once the orchestrator started seeing fleet + SWARM shard sources via
list_running_deckies (a844148), every event row landing on a fleet decky
broke the FK to topology_deckies — the column now carries opaque ids
("local:omega-decky" for fleet, "host_uuid:decky_name" for shards) that
will never match topology_deckies.uuid.
Symptom on the operator's mothership:
IntegrityError 1452 — orchestrator_events_ibfk_2 FK violated on every
tick once the reconciler populated fleet_deckies.
Index on dst_decky_uuid is preserved (the dashboard reads
"events for this decky" frequently); only the FK is removed. Keeps
data integrity loose by design — events are append-only history that
should outlive the deckies they reference.
Existing MySQL deployments need the FK dropped manually:
ALTER TABLE orchestrator_events
DROP FOREIGN KEY orchestrator_events_ibfk_2,
DROP FOREIGN KEY orchestrator_events_ibfk_1;
SQLite users are unaffected — SQLite doesn't enforce FKs by default.
