Request changes — the Make Your Move / Exorcise correction is valid, but the shared P/T distributor is invoked before the search grammar has finalized each leg's syntactic type scope.
🟡 Medium
parse_search_filter_disjunction normalizes independently parsed segments and immediately calls distribute_properties_to_or at crates/engine/src/parser/oracle_effect/search.rs:1075-1104. The P/T gate in crates/engine/src/parser/oracle_target.rs:4779-4781 decides whether to distribute from the receiver's current type_filters, while the generic card fallback at search.rs:1528-1557 can construct a typed leg with no concrete type. That leaves a path where a trailing P/T predicate is assessed against unfinished scope rather than the completed disjunction. This is a correctness gap beyond the two changed cards; the current regression test covers explicit artifact/enchantment/creature and Vehicle legs but not the generic/Any shape.
Evidence: CR 208.3 says, “A noncreature permanent has no power or toughness,” so a P/T constraint must be attached only after the grammar can establish which leg is creature-scoped. The checked-in rules text is at docs/MagicCompRules.txt:1519.
Please make the search path scope-aware before P/T distribution, preserving the existing semantics of standalone article-led/generic legs rather than unconditionally routing it through the target-parser finalizer (whose core-type backfill can narrow those shapes). Add an end-to-end search-parser regression with a generic/Any branch that proves both (1) the intended creature-scoped leg retains the P/T predicate and (2) unrelated/generic legs do not acquire an incorrect type restriction or P/T predicate. Keep the existing explicit-type coverage as the positive control.
Recommendation: request changes for a scope-aware repair plus the generic-branch regression; do not enqueue this head.
…ble type Review follow-up on phase-rs#7472. The CR 208.3 gate this PR added answers "is a power/toughness restriction VACUOUS on this leg?", which is only half the binding question. A leg that names no card type at all is not vacuous, so it was accepted — and a restriction printed on a sibling `creature` noun silently narrowed a disjunct whose own text never mentioned creatures. Measured on the pre-fix head, through the real search grammar: a green card or a creature card with power 4 or greater -> [Card] leg wrongly inherits power >= 4 a permanent card or a creature card with power 4 or greater -> [Permanent] leg wrongly inherits it a card named Llanowar Elves or a creature card with power 4 or greater -> the name-only leg (no type filters) wrongly inherits it CR 208.1: a postnominal modifier binds to the noun it follows. None of those legs is that noun. `prop_distributes_to_leg` now consults a three-valued verdict, `leg_admits_creature_pt`: 1. CR 205.2b - the leg guarantees creature ("artifact creature") -> accept 2. CR 208.3 - the leg pins a noncreature card type -> reject 3. the leg names no card type scope at all -> reject Case 3 is decided by a new exhaustive sibling of the two predicates this PR already added, `type_filter_names_a_card_type_scope`. `Permanent`, `Card` and `Any` are "whatever its type" quantifiers naming no card type (CR 205.2a enumerates the card types; CR 110.1, CR 108.2); every other variant names a card type or a subtype pool (CR 205.3), so `Subtype("Goblin")` and `Non(_)` keep distributing and the CR 205.3m creature-subtype class is unaffected. The gate now FAILS CLOSED. A leg still naming no type - because a backfill has not run, or could not resolve it - is left unrestricted rather than wrongly restricted. Ordering is therefore load-bearing for precision, not for safety: `finalize_or_disjunction` still backfills first so resolvable `[Any]` legs are decided on their real type, but `oracle_effect::search`, which composes its own `Or` from independently parsed segments and runs no backfill, is now merely coarser rather than wrong. That is why the search grammar is deliberately NOT routed through `finalize_or_disjunction`: `distribute_core_type_to_or` rewrites only an exactly-`[Any]` leg, so it is a no-op on every leaking shape above, while it CAN project one segment's core type onto a standalone article-led segment that never named it. `pt_hosting_leg_props` / `strip_misplaced_pt_props_from_or_legs` stay keyed on `leg_pins_noncreature_core_type` and NOT on the new gate; the "exact complement" doc is corrected to say why. That sweep relocates a restriction off a leg where it is vacuous, while the gate refuses to place one where it does not belong. A type-open leg is ineligible under the gate but is not vacuous, so widening the sweep to it would delete a live predicate from the leg that syntactically parsed it - exactly what the PR's invariant 5 forbids. Tests: * `search_disjunction_leaves_type_open_legs_unbound_by_pt_suffix` - end to end through `parse_search_filter`, five rows covering `[Card]`, `[Permanent]`, no-type-filters, and a type-open leg sitting between a pinned leg and the creature leg. Each row asserts the creature leg RETAINS the predicate, the type-open leg does not acquire it, and the type-open leg's `type_filters` still equal exactly what its own text named (so a future backfill that narrows it fails here instead of passing silently). A CR 202.3 mana-value row is the discriminator against a blanket "never distribute to a generic leg". * `leg_admits_creature_pt_rejects_type_open_legs_but_keeps_creature_scopes` and `distribute_skips_pt_on_a_type_open_leg_but_still_distributes_cmc` - the same claims at the building-block level, with `Subtype("Goblin")` and CR 205.2b accept controls that a naive "reject unless provably creature" gate fails.

Addressed — the gap was real, and it is wider than the @matthewevans was right on both counts: there was a path where the P/T predicate was assessed against unfinished scope, and routing through What the search grammar actually producesInstrumented
Two things fall out of that:
The fix
Case 3 is decided by a new exhaustive sibling, The gate now fails closed, which is the part that answers the review directly. A leg that still names no type — because a backfill has not run, or could not resolve — is left unrestricted rather than wrongly restricted. Ordering is therefore load-bearing for precision, not for safety: Deliberate asymmetry (worth flagging)
Tests
The existing explicit-type coverage is retained unchanged as the positive control, as requested. |

Request changes — the P/T distribution gate still lets an exclusion-only leg inherit a predicate that grammatically belongs to the creature leg.
🔴 Blocker
[HIGH] Non(Artifact) is treated as creature-admitting even though it also matches noncreature permanents. Evidence: crates/engine/src/parser/oracle_target.rs:4826-4838 first rejects only creature-guaranteeing or definitely-noncreature legs, then accepts any type_filter_names_a_card_type_scope; that helper includes TypeFilter::Non(_) at :4772-4784. distribute_properties_to_or consequently pushes every trailing P/T property to that receiver at :5071-5080. The parse of target nonartifact or creature with power 4 or greater therefore restricts the standalone nonartifact leg too, excluding a nonartifact noncreature (for example, an enchantment) because CR 208.3 says: “A noncreature permanent has no power or toughness.” The postnominal P/T predicate belongs to the creature disjunct; an exclusion alone is not a creature anchor.
Suggested fix: make the shared admission predicate require a positively creature-anchored receiver (while retaining the explicit creature and creature-subtype cases), instead of treating any scoped exclusion as eligible. Add parser and production-pipeline coverage where a nonartifact noncreature remains targetable while a small creature is rejected.
✅ Clean
The current search-specific repair correctly rejects type-open legs, so this finding is limited to the remaining exclusion-only shape; it does not require routing that grammar through the target finalizer.
Recommendation: request changes for the creature-anchored admission rule and the runtime discriminator; do not enqueue this head.

… P/T suffix Review follow-up on phase-rs#7472. The previous gate asked whether a leg was SCOPED at all, which let an exclusion-only leg through. CR 205.4b: `Non(Artifact)` narrows a leg to nonartifacts, but every noncreature nonartifact permanent still satisfies it, and CR 208.3 gives those no power - so distributing the creature leg's restriction there deletes the whole first disjunct. Measured on the pre-fix head via parse_target: target nonartifact or creature with power 4 or greater -> [Any, Non(Artifact)] wrongly inherits power >= 4 target nonartifact permanent or creature with power 4 or greater -> [Permanent, Non(Artifact)] wrongly inherits it target nonland permanent or creature with power 4 or greater -> [Permanent, Non(Land)] wrongly inherits it target non-Human or creature with power 4 or greater -> [Any, Non(Subtype(Human))] wrongly inherits it target noncreature or creature with power 4 or greater -> [Any, Non(Creature)] correctly gated already `type_filter_names_a_card_type_scope` is REPLACED by `type_filter_anchors_creature`, which asks the CR 208.1 question directly: does this leg name a noun that could be a creature? Only `Creature` (CR 205.2a) and a creature-capable subtype pool (CR 205.3m, delegated to `is_noncreature_core_type_pin` so the subtype split keeps one authority) anchor. This is a replacement rather than a fourth sibling predicate: an unanchored leg covers the type-open shapes too, so the previous rule is subsumed. Two shapes beyond the reported one are fixed by the same rule, for the same reason they would otherwise have been left behind: * `Kindred` alone no longer anchors - CR 308.1, each kindred card has ANOTHER card type, so the word names no creature. * `AnyOf` anchors only when EVERY alternative does - CR 301.7a leaves an uncrewed Vehicle with no power, so AnyOf[Creature, Subtype(Vehicle)] must not receive the restriction. Tests: * `exclusion_only_leg_admits_a_powerless_enchantment_but_still_excludes_artifacts` drives the real cast pipeline: a powerless enchantment becomes a legal target (it was illegal pre-fix), with an artifact as the reach-guard proving the filter still discriminates. The reviewer-suggested "small creature is rejected" pairing is deliberately NOT asserted - a 2/2 creature IS a nonartifact permanent, so once the exclusion leg is correctly unrestricted the small creature is legal THROUGH that leg (CR 115.1a); asserting otherwise would encode a bug. Reasoning recorded in the test doc. * `leg_admits_creature_pt_rejects_unanchored_legs_but_keeps_creature_scopes` covers the exclusion-only, Kindred and AnyOf-Vehicle reject rows, and keeps Subtype(Goblin) / CR 205.2b artifact-creature / creature-plus-negation as accept controls so the gate cannot collapse into rejecting everything.

Confirmed and fixed in The finding, measured
Exactly as described: an exclusion narrows a leg without naming a creature, and every noncreature nonartifact permanent still satisfies it. The fix
This is a replacement rather than a fourth sibling predicate: an unanchored leg covers the type-open shapes too, so last round's rule is subsumed. Two shapes beyond the reported one fall to the same rule, and I fixed them in the same commit because they were holes for the identical reason — patching only
On the requested discriminator — I did not write it, deliberately
The first half is now asserted end to end. The second half is not assertable for this shape, and asserting it would encode a bug. A 2/2 creature is a nonartifact permanent, so once the exclusion leg is correctly unrestricted, the small creature is legal through that leg (CR 115.1a). That is the printed meaning of "target nonartifact permanent or creature with power 4 or greater" — the first disjunct carries no power restriction at all. A test demanding its rejection would only pass while the exclusion leg still wrongly carried the predicate, i.e. it would pin the very defect this fixes.
then casts and asserts the enchantment reaches the graveyard. The reasoning for the substitution is recorded in the test's doc comment. If you would rather have a different reach-guard, say which and I will swap it.

Summary
Fixes a parse-fidelity defect on Make Your Move.
Issue: "power 4 or greater" is applied to all three Or-filters; per the card it restricts only "creature" (any artifact/enchantment is a legal target regardless of power — CR 208.3: noncreature permanents have no power).
