const DEAD_TABLE_DROPS: &[&str];Expand description
Tables retained by the old chain only for a downgrade path the flatten
abandons. Dropped from any legacy DB by the adopt step; never created
by the flat schema. db_workflow_* data was already copied into
db_drone_* by the old v10 migration, so dropping loses nothing.
db_identities (the pre-v11 name), db_identity_bundles, and
db_identity_bindings were dropped outright rather than renamed
forward in Phase 4c of SPEC_PRESET_TO_BUNDLE_REFACTOR_2026_07_02.md —
db_agent_identity_links/db_accounts is the sole credential-
resolution path (identity/resolver/inject.rs::resolve_bindings_for_instance),
confirmed via the already-applied m0013/m0014 backfill migrations
(see SPEC_ARMORY_PHASE4_STORAGE_RENAME_COMPLETION_2026_07_12.md §6/§8a).
