fifa17-migration-invariants.py Pre/post invariants across every domain the
migration authorization names: coins, ownership (+kind histogram, distinct
definitions, chemistry styles, loans, position overrides), squads,
managers, staff, consumables, club items, transfer state (market_listings),
packs, SBC, match history, plus integrity_check and foreign_key_check.
Table names are the REAL schema, not guessed: transfer state lives in
market_listings (29 rows in production), the FIFA17 opaque squad blob in
game_entity_ext.
fifa17-migration-rehearse.py Serves a migrated COPY with the candidate Rust
stack on isolated ports and validates the wire surface: club discardValue
is table-derived, squad projects, consumable categories populate, and the
apply probe is OFF (502 upstream-unavailable rather than a diagnostic ack).
Both are read-only against production: the rehearsal operates on a copy under
/home/alex/openfut-migration/, and nothing under openfut-promotion/state is
opened.
Evidence from the 2026-08-22 rehearsal is written up in the Vault runbook
"FIFA17 Rust Production Migration (rehearsed)".
