POST /ut/game/fifa17/item/resource/<rid> {"apply":[{"id":N}]} now performs a
durable atomic contract application instead of falling through to Python.
THE RULE. grant = fcc_contractcards[card][tier(TARGET.rating)], then
min(99, contract + grant). The column is keyed on the TARGET's tier, NOT the
card's own -- all 36 cells of EA's shipped table match the published FIFA 17
matrix, and staging discriminates the two readings outright: a bronze-RARE
card on a rating-89 player granted 3 (the gold column), where the card-level
reading predicts 15.
No client binary reads fcc_contractcards -- a string scan of every .exe/.dll
in the install finds it referenced nowhere, and CardsDLL reads only 14 fcc_
tables (fcc_discardcoins among them, which is why quick-sell prices locally).
Consumable effects are server-authoritative, so EA's shipped table is the only
non-invented source and the client renders whatever we persist and re-serve.
The host computes the grant, Core owns the mutation -- the same split
quick-sell already uses (host prices via discard_value, Core performs
sell_item), and what migration 0027 means by "Core defines NO per-category
formula".
FAILS CLOSED, never 200-and-do-nothing: manager contracts 409 because staff
ratings are unimported so the target tier is unknowable; every other family
409 as unproven; batch 400; unresolvable operand 404. Core's deterministic
refusals pass through with their own status instead of collapsing to 503,
which would tell the client to retry a request that can never succeed.
`contract: 7` stops being a hardcode in shape_item/shape_staff_item and
becomes the fallback for an instance Core tracks no contract for. `fitness: 99`
is the same class of hardcode and is deliberately untouched.
CLEAN CUTOVER: Route::ConsumableApplyProbe, its handler, apply_probe_enabled,
the OPENFUT_FIFA17_APPLY_PROBE gate and both probe scripts are deleted. A
handler no classifier can reach is this repo's recurring defect class, and the
new economy arm preempts the probe. fifa17-migration-rehearse.py also drove
the probe (spelled "apply probe", so an apply-probe grep missed it) and would
have eaten a card off the rehearsal profile; retargeted to a non-mutating
assertion.
Not implemented, on purpose: the stored-manager bonus (real mechanic, rule
appears in no shipped table -- guessing it would corrupt the proven part) and
contract decrement per match (nothing spends contracts yet).
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)".
