Correct the CR 400.7 attribution.

Exercise the failure path through production events.
steal_then_bury directly assigns base_controller and controller, so it does not exercise the control-change path. move_to_zone is a production helper, but these rows do not process its emitted GameEvent::ZoneChanged through the replacement-aware ProposedEvent::ZoneChange pipeline. The availability-only assertions can therefore pass without testing replacement or control-change behavior. Execute the corresponding cast and land-play actions, and assert that they complete.

Changes requested — exercise the graveyard-permission fix through the casting pipeline and correct the CR attribution.
🟠 Runtime coverage gap
crates/engine/src/game/casting.rs:3571-3574 changes the normal graveyard cast authority, and :13397-13399 plus :13480-13490 use that authority for Bestow. The new rows at crates/engine/tests/integration/graveyard_permission_owner_zone.rs:167-173 and :213-218 only enumerate available actions; they do not submit a normal GameAction::CastSpell, nor do they drive Bestow's cast/choice route. A reversion or incorrect owner/LKI lookup in those downstream paths can therefore pass this suite.
Please add owner-vs-controller/LKI-divergent regressions that execute both a normal GameAction::CastSpell and a Bestow cast/choice from the graveyard, asserting the action completes and the permission is rejected for a non-owner.
🟠 CR attribution
The comments at graveyard_permission_owner_zone.rs:34-35 and :109-110 attribute turns.rs's LKI-cache clearing to CR 400.7. The verified rule establishes that a zone-changing object becomes a new object; it does not prescribe this engine's cache lifetime. Please remove that cache-clearing attribution (while retaining a narrowly accurate zone-identity reference if useful).
The branch is also BEHIND and three required Rust test shards remain in progress. The available SHA-bound artifact reports zero parse changes, but the required <!-- coverage-parse-diff --> sticky is not present. Those are evidence gates to recheck after a corrected head; the missing runtime coverage and inaccurate CR attribution are the merge blockers.
Recommendation: request changes; do not enqueue until the production cast paths and CR comment are corrected.

Assert the specific bestow-rider rejection.
result.is_err() accepts every cast failure. An unrelated cast validation (such as missing targets for the Aura host) can satisfy this assertion.
The reach guard castable.contains(&bestowed) proves the permission matched during enumeration. It does not prove that the has_graveyard_cast_permission_without_keyword_constraint check at crates/engine/src/game/casting.rs:13481–13491 caused the refusal.
The rider-only rejection produces EngineError::InvalidAction("No legal bestow cast from graveyard".to_string()) — a specific, stable error message. Assert this error variant or message to prove the input reached the keyword-constraint consumer and the refusal came from that path, not from a preceding check.
Repository conventions require: "For every negative assertion, require a paired positive reach-guard proving the input actually reached the code under test." The existing reach guard proves the permission matched. Add an assertion that proves the CastSpell action failed with the rider-specific error message.

Changes requested — the Bestow regression still does not cover the changed matcher.
Runtime regression coverage
crates/engine/src/game/casting.rs:5296-5312 only evaluates
matches_target_filter_for_zone after proving that the permission filter has
no Bestow keyword constraint. The new test instead installs
FilterProp::HasKeywordKind { Bestow } at
crates/engine/tests/integration/graveyard_permission_owner_zone.rs:520-529.
That makes the first condition at casting.rs:5299 false, so the changed
owner/LKI matcher at :5303 is short-circuited and is not witnessed by this
fixture. Its spell_objects_available_to_cast reach guard (:537-546) covers
the separate enumeration consumer, while result.is_err() (:548-563) can
pass for an unrelated cast failure. CodeRabbit's current-head review identifies
the same broad-error issue.
Please add a production Bestow fixture with an unconstrained graveyard
permission and an assertion that distinguishes the actual keyword-constraint
consumer from a controller/LKI reversion. If the existing plain-permission
Bestow path prevents a completing cast, make the expected downstream outcome
specific enough to prove this matcher was evaluated, or address that blocking
path rather than treating the rider-only refusal as coverage for it.
Current-head evidence gate
The only <!-- coverage-parse-diff --> receipt is bound to
9e89833c6838172ba02572ed0fac87dd0a3de95a, not this head
1e4565e36b90607cc3da4a904f5a72b0dfa1f7e1; publish and reconcile a
current-SHA receipt, even if it again reports no parse changes. Required Rust
lint/tests/card-data checks are also still in progress.
The shared matcher is the appropriate seam, and the earlier CR 400.7
attribution has been corrected; the remaining blocker is discriminating
current-head evidence. Do not enqueue until the regression and evidence gates
are complete.
A card that died under an OPPONENT'S control was silently refused by its own
owner's graveyard permission. MEASURED, with a printed Ramunap-Excavator-shaped
source and the land's owner querying:
land owner=P0 live_controller=P0 lki_controller=Some(P1)
before: graveyard_lands_playable_by_permission(state, P0) -> []
after: -> [(land, source)]
So Muldrotha, Karador, Lurrus and Ramunap Excavator all declined a card their
controller owns, whenever an opponent happened to control it when it died.
THE RULE IS UNAMBIGUOUS. CR 109.4: "Only objects on the stack or on the
battlefield have a controller. Objects that are neither on the stack nor on the
battlefield aren't controlled by any player." None of its six exceptions covers
a card in a graveyard. CR 108.4a then says anything asking for such a card's
controller must "use its owner instead", and CR 109.5 says the same of the word
itself -- "you"/"your" refer to "its owner (if it has no controller)".
WHAT ACTUALLY DIVERGED -- not the live `controller` field. `zones.rs`'s
`reset_for_battlefield_exit` forces `base_controller = Some(owner)` and the
destination-keyed reset then writes the owner back (citing these same rules), so
a graveyard card's live controller is already correct. The divergence is the LKI
CACHE: `filter::effective_controller` reads `state.lki_cache[id].controller` for
any object off the battlefield/stack under `ControllerLookup::LiveOrLki`, and the
LKI snapshot is taken BEFORE that reset -- so it holds the THIEF.
`matches_target_filter_in_owner_zone` passes `LiveOnly`, which is what cures it.
Exposure was one step, not permanent: `turns.rs` clears the LKI cache on step
transition (CR 400.7). The failure direction is MIS-EXCLUSION only -- the owner's
own card is refused, never another player's admitted -- so nothing depended on
the old behaviour.
THE FIX. Route all four graveyard-permission consumers in `game::casting`
through `filter::matches_target_filter_for_zone`, the documented single authority
for the zone-ownership substitution (`filter::is_owner_scoped_zone` is already
`Hand | Library | Graveyard`):
graveyard_object_castable_by_permission_sources (cast enumeration)
graveyard_permission_source (elected cast authority)
has_graveyard_cast_permission_without_keyword_constraint
graveyard_lands_playable_by_permission (land play)
ALL FOUR TOGETHER, deliberately. Enumeration and election are separate consumers;
converting a subset would let the list of offers disagree with what a cast is
actually allowed to do -- a worse failure than today's uniform one.
EXILE IS DELIBERATELY NOT CONVERTED. `is_owner_scoped_zone` excludes it, and its
doc names the class that depends on the exclusion: "creatures they controlled
that were exiled this way" is keyed on who controlled the object when it left,
so the at-exile LKI controller is load-bearing there. In particular
`exile_land_playable_by_static_permission` keeps `matches_target_filter`.
TESTS. `graveyard_permission_owner_zone.rs` -- three rows, all built on a
PRINTED permission rather than any one card's parsed text, because the defect is
class-wide.
a_land_that_died_under_an_opponents_control_is_still_its_owners_to_play
a_spell_that_died_under_an_opponents_control_is_still_its_owners_to_cast
the_owner_substitution_does_not_widen_to_another_players_card
The land and cast halves are separate rows because they are served by DIFFERENT
consumers, so one row cannot cover both. The third pins that the fix substitutes
the owner axis rather than dropping it.
Every row goes through the production zone-change path (`zones::move_to_zone`)
rather than hand-setting fields, and asserts the fixture really is in the
divergent state (live controller == owner, LKI == thief) BEFORE asserting
anything about permissions -- without that staging guard the rows would pass
vacuously the moment a step boundary cleared the LKI cache.
Mutation-verified: reverting the four call sites turns all three red, each
reporting the exact `got []` it guards.
Verified: 21230 lib tests pass, 0 failed; 6936 integration pass; clippy
--all-targets -D warnings clean; fmt clean. One integration failure,
`flamewar_mtmte_export::production_export_has_canonical_pack_tactics_conditions_for_all_eight_cards`,

this change reverted ("Battle Cry Goblin must export a canonical trigger
condition"). Not touched here.

…wner axis Addresses @matthewevans' second review on phase-rs#8860. The previous bestow row could not witness the changed matcher, exactly as reported. `has_graveyard_cast_permission_without_keyword_constraint` short-circuits on its FIRST conjunct, `!filter_has_keyword_kind_constraint(source.filter, kind)`, so installing `FilterProp::HasKeywordKind { Bestow }` made that conjunct false and the owner/LKI matcher on the third conjunct was never reached. The row also leaned on a bare `result.is_err()`, which CodeRabbit correctly flagged as satisfiable by an unrelated failure. Replaced with two rows: `the_bestow_keyword_constraint_consumer_resolves_against_the_owner` installs an UNCONSTRAINED permission (the plain Muldrotha shape), so the first conjunct passes and execution reaches the matcher, then asserts the consumer's own verdict POSITIVELY for a card whose LKI controller is the thief -- plus a paired negative proving the owner axis is substituted, not dropped. Reaching the consumer from an integration test needs a `#[doc(hidden)]` accessor, since it is `fn`-private and production-reachable only from the bestow lane. `bestow_cast_from_graveyard_is_blocked_by_the_aura_form_type_seam` pins the blocking path rather than leaving it as an unexplained gap. ROOT CAUSE of that blocker, measured rather than assumed: `handle_bestow_cost_choice_with_payment_mode` calls `apply_bestow_aura_form` -- which strips the Creature core type per CR 702.103b -- BEFORE calling `prepare_spell_cast_with_variant_override`. That re-derives the graveyard permission, whose filter is `creature cards`, against a card that is no longer a creature, so the cast is refused with "Card is not in a castable zone". CR 702.103b places the form change "as a spell cast bestowed is put onto the stack", i.e. at CR 601.2a and AFTER the permission has authorized the cast, so re-deriving the permission from post-change types is the defect. Independent of this PR: the diff touches neither `apply_bestow_aura_form` nor any type filter, and the refusal reproduces with no control change at all. The row asserts that specific message, so if the seam is fixed the row fails loudly and the consumer row can be promoted to full cast-path coverage. Mutation-verified: reverting the four call sites turns all seven owner-scoping rows red, including the new consumer row, while the blocker row correctly stays green.

Changes requested — the Bestow regression still bypasses the production consumer.
🟡 Runtime coverage gap
crates/engine/src/game/casting.rs:13413-13511 has a reachable production route for the fourth matcher: a graveyard card is first admitted by graveyard_permission_source (:13413-13415), and when no creature is a legal Bestow target, :13426-13434 skips the Aura-form route and :13496-13511 queries has_graveyard_cast_permission_without_keyword_constraint before falling through to the normal graveyard cast.
The new fixture instead creates a legal host at crates/engine/tests/integration/graveyard_permission_owner_zone.rs:458-461 and directly calls the new #[doc(hidden)] pub accessor at crates/engine/src/game/casting.rs:5296-5305. That proves the helper's boolean, but it does not prove that the production cast path reaches the helper; reverting only the changed owner-zone matcher can leave this direct-call test green while the no-target fallback rejects the owner's stolen-then-buried card. The exported test-only API is unnecessary once the behavior is exercised through the action pipeline.
Please replace this direct accessor test with a stolen-then-buried Bestow creature under an unconstrained creature-cast permission, no legal creature target, and sufficient normal mana. Submit GameAction::CastSpell and assert the normal cast completes; retain the owner-negative. This exercises the changed consumer without entering the separately documented Aura-form failure path.
The normal cast/land rows and the correction to the earlier cache-lifetime CR attribution are clean. The current parse-diff sticky receipt is still not visible for this SHA, and required Rust test shards are pending; recheck those after the discriminating regression lands.
Recommendation: request changes; do not enqueue until the production fallback is covered and current-head evidence is complete.
Split out of #8812 review, where both reviewers flagged it. Pre-existing bug; independent of that PR.

game::castingthroughfilter::matches_target_filter_for_zone, the documented single authority for the substitution (filter::is_owner_scoped_zoneis alreadyHand | Library | Graveyard):graveyard_object_castable_by_permission_sourcesgraveyard_permission_sourcehas_graveyard_cast_permission_without_keyword_constraintgraveyard_lands_playable_by_permissionAll four together, deliberately. Enumeration and election are separate consumers; converting a subset would let the list of offers disagree with what a cast is actually allowed to do — a worse failure than today's uniform one.
Exile is deliberately NOT converted.
is_owner_scoped_zoneexcludes it, and its doc names the class that depends on the exclusion: "creatures they controlled that were exiled this way" is keyed on who controlled the object when it left, so the at-exile LKI controller is load-bearing there.exile_land_playable_by_static_permissionkeepsmatches_target_filter.Tests
graveyard_permission_owner_zone.rs— three rows, all built on a printed permission rather than any one card's parsed text, because the defect is class-wide:a_land_that_died_under_an_opponents_control_is_still_its_owners_to_playa_spell_that_died_under_an_opponents_control_is_still_its_owners_to_castthe_owner_substitution_does_not_widen_to_another_players_cardThe land and cast halves are separate rows because they are served by different consumers, so one row cannot cover both. The third pins that the fix substitutes the owner axis rather than dropping it.
Every row goes through the production zone-change path (
zones::move_to_zone) rather than hand-setting fields, and asserts the fixture really is in the divergent state (live controller == owner, LKI == thief) before asserting anything about permissions — without that staging guard the rows would pass vacuously the moment a step boundary cleared the LKI cache.Mutation-verified: reverting the four call sites turns all three red, each reporting the exact
