- Around line 6023-6026: Bind each GameEvent::SpellCast to its specific cast
record or recorded mana value instead of looking up the newest matching
spell_object_id via rev().find(...). Update event creation and resolution to use
that bound value, ensuring an earlier X=4 cast still resolves with 4 after a
later cast with a different X; add a regression covering this ordering and
preserve look-back effects’ use of the relevant earlier action.
In `@crates/engine/tests/integration/thor_god_of_thunder.rs`:
- Around line 50-59: Update the test setup around forth to use a production
counterspell or zone-change action that routes through the replacement-aware
ProposedEvent::ZoneChange pipeline, leaving Thor’s trigger pending before
resolution; remove the direct zones::move_to_zone call and manual stack retain,
while preserving the intended pre-resolution state.

Changes requested — the cast-time mana value must be bound to the triggering cast, and the regression must exercise the legal event pipeline.
🔴 Blocker
-
crates/engine/src/game/quantity.rs:6023-6028reverses the player's cast-history records and selects the newest entry with the samespell_object_id. That is not necessarily theGameEvent::SpellCastthat created the pending Thor trigger: casting the same object again with another X before the earlier trigger resolves makes the earlier trigger use the later X. Carry a stable cast-record identity or the recorded mana value on the triggering event, then resolve from that event-bound value. Add an ordering regression with two casts at different X values and the earlier trigger resolving after the later cast has been removed. -
crates/engine/tests/integration/thor_god_of_thunder.rs:50-59callszones::move_to_zoneand removes a stack entry directly. Those mutations bypass the replacement-aware zone-change and stack-resolution paths, so the test can pass for a state legal engine actions cannot produce. Replace them with a real legal counter/zone-change path that leaves Thor's trigger pending and verifies the same off-stack behavior.
Recommendation: request changes with an event-bound cast-value record and a production-pipeline regression, then re-request review on the new head.

Approved. Current-head review is clean; required CI is green and the current parse-diff reports no card-parse changes.

Summary
Fixes Thor, God of Thunder so its second ability uses a triggering spell's cast-time mana value, including announced X. The review follow-up binds that value to the

Claimed parse impact
None. The Oracle parser and card-data AST are unchanged; this is a runtime event/protocol and test-pipeline fix.
Scope Expansion
None. The review follow-up expands the serialized
SpellCastevent with an optional cast-time snapshot, updates legacy constructors/client typing, adds response-driving methods to the test harness, and replaces the direct-mutation regression with legal apply-pipeline tests.Validation Failures
None. A fresh review initially restated a blocker contradicted by the current test; an independent cross-check verified
thor_binds_same_object_recasts_to_their_own_cast_valuescovers the requested Counterspell/Flashback ordering.CI Failures
None.
