📝 Walkthrough

Walkthrough

The change adds enters_attacking to Dig effects, parser continuations, choice state, replacement events, and zone delivery. Battlefield-bound cards retain this flag through pauses and replacements before entering combat. A Winota integration test covers tapped-and-attacking entry.

Changes

Dig attacking-entry behavior

Layer / File(s) Summary
State and event contracts
crates/engine/src/types/*, crates/engine/src/parser/oracle_ir/ast.rs, crates/engine/src/game/zone_pipeline.rs
Ability, Dig choice, zone-change, pending-delivery, proposed-event, and parser AST records now include a defaulted enters_attacking field.
Oracle parser propagation
crates/engine/src/parser/oracle_effect/*
Dig destination parsing reads battlefield attacking qualifiers and propagates them through Dig continuations.
Dig resolution and zone delivery
crates/engine/src/game/effects/dig.rs, crates/engine/src/game/engine_resolution_choices.rs, crates/engine/src/game/zone_pipeline.rs, crates/engine/src/game/effects/counters.rs
Dig resolution and deferred zone delivery preserve the flag. Successful battlefield delivery enters the object into combat when the flag is set.
Combat target selection and integrations
crates/engine/src/game/combat.rs, client/src/*, crates/phase-ai/src/*, crates/engine/tests/integration/*
Entry-attack target selection supports zero, one, or multiple legal targets. The client and AI handle the new waiting state. A Winota integration test verifies tapped-and-attacking entry.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🔴 Critical · up to e0d2c

This PR makes cards enter combat attacking, but the current head still loses that state across several entry paths, can stop processing remaining cards after a target prompt, and has unresolved defender and attacker-state handling issues. These defects can create incorrect combat results or incomplete card moves, so the PR is not safe to merge until they are fixed.

4689-4700: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Record the combat-state write for attacking entries.

When enters_attacking is true, Effect::Dig changes combat state in addition to zone membership. This arm currently records only membership and hand/library writes. The ordering profiler already uses StateKind::TurnStructure for combat mutations, so this omission can permit incorrect ordering with effects that read or write combat state. CR 508.4 defines a creature put onto the battlefield attacking as attacking as it enters. (media.wizards.com)

Add a conditional StateKind::TurnStructure write and a regression test that orders an attacking Dig with a combat-state effect.

Proposed fix
         Effect::Dig {
             player: _,
             count,
             filter: _,

             rest_destination: _,

         } => {
             let mut p = ext_write(StateKind::SetMembership);
             p.writes_external.set(StateKind::HandLibrary);
             p.writes_membership_external_census.merge(Census::Any);
             p.writes_membership_external_zones.merge(ZoneSpan::Any);
             p.merge(rw_quantity_expr(count));
+            if *enters_attacking {
+                // CR 508.4: a creature put onto the battlefield attacking is attacking.
+                p.writes_external.set(StateKind::TurnStructure);
+            }
             if let Some(kc) = keep_count_expr {
                 p.merge(rw_quantity_expr(kc));
             }

795-815: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Carry eff_attacking through paused fast paths.

When eff_attacking is true, these calls still pass false to execute_zone_move. The Done branches call enter_attacking, but the NeedsChoice branches return before that call. They also do not store eff_attacking in a PendingChangeZoneIteration.

If a replacement or counter pause occurs, the resumed permanent can enter the battlefield without being added to combat.attackers. Store the flag in the pause carrier and apply it once after resumed delivery, or route these paths through the same terminal handling as process_one_zone_move_with_terminal. Add a regression that combines enters_attacking: true with a replacement choice.

This affects the PR's Winota/Dig attacking-entry objective and CR 508.4 behavior. As per path instructions, crates/engine/** must preserve the replacement-aware zone-move pipeline and verified rules behavior.

crates/engine/src/game/effects/reveal_until.rs (1)

106-120: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

resolve_choose_any_number drops the effect's enters_attacking value.

resolve() destructures enters_attacking from Effect::RevealUntil and forwards it correctly to the direct battlefield-entry branch and to WaitingFor::RevealUntilKeptChoice. The ChooseAnyNumber disposition takes a different path: resolve_choose_any_number has no enters_attacking parameter, and the WaitingFor::DigChoice it builds at line 527 hardcodes enters_attacking: false. A "reveal until ..., put any number of those cards onto the battlefield ... tapped and attacking" instruction reaches this disposition, so this silently disables attacking entry for that shape, unlike every other battlefield-entry branch in this file.

Add an enters_attacking: bool parameter to resolve_choose_any_number, forward it from the call site at the ChooseAnyNumber dispatch, and use it instead of the literal false in the WaitingFor::DigChoice construction.

1012-1059: 🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Fix: enters_attacking is dropped when ChangeZone upgrades to ChangeZoneAll.

The destructure at lines 1014-1023 does not name enters_attacking; the .. on line 1023 silently discards it instead of binding it. The constructed ChangeZoneAll at line 1050 then hardcodes enters_attacking: false instead of forwarding the original value.

Any card whose delayed, tracked-set-driven ChangeZone effect carries enters_attacking: true (a CR 508.4 "enters the battlefield already attacking" instruction) loses that instruction the moment this upgrade runs. This defeats the propagation this PR is adding.

Contrast with crates/engine/src/game/effects/overload.rs, which explicitly names enters_attacking: _ in its analogous upgrade and documents why the drop is intentional there ("hidden-zone exile, combat irrelevant"). This site has no such field or rationale — it is an omission, not a deliberate choice.

🐛 Proposed fix to forward `enters_attacking`
         Effect::ChangeZone {
             destination,
             origin,
             target,
             enters_under,
             enter_tapped,
+            enters_attacking,
             enter_with_counters,

Preserve enters_attacking in the mass-entry branch.

parse_battlefield_entry_qualifiers already returns enters_attacking, but this ChangeZoneAll construction replaces it with false. A clause such as put all ... onto the battlefield tapped and attacking therefore loses its attack instruction. The single-object branch preserves the value at Line 34167.

Use the parsed value and add a regression that reaches ChangeZoneAll with an attacking qualifier.

Proposed fix
-                        enters_attacking: false,
+                        enters_attacking,

As per path instructions, the engine must preserve strict MTG Comprehensive Rules fidelity; the surrounding parser documents this behavior under CR 508.4.

The PR objective explicitly requires attack instructions to propagate through mass entry effects.

Resume all kept battlefield cards after an entry-attack prompt.

When the first kept card raises EntryAttackTargetChoice, this return exits the for &obj_id in &kept loop. The deferred completion still publishes kept.clone(). Later cards can remain in the library while downstream tracked-set consumers treat them as delivered.

Resume the remaining cards through PendingChangeZoneIteration and drain_pending_change_zone_iteration, as the EffectZoneChoice path does. Add an integration test with at least two kept battlefield cards and an entry-attack target prompt.

Based on path instructions: “Check edge cases when relevant: ... multi-target/modal/repeat-for interactions” and tests must drive the production pipeline. The PR objective explicitly includes propagating attack instructions through mass entry effects.

Reuses a meld-specific title for a non-meld entry-attack prompt.

The merged branch for MeldAttackTargetChoice and EntryAttackTargetChoice always renders t("gamePage.meld.chooseAttackTarget"). For the Winota entry-attack flow, the prompt has no relation to melding, so a user sees a meld-labeled title while choosing an attack target for a creature that just entered the battlefield.

Add a shared, mechanic-neutral i18n key (or select the title based on waitingFor.type) so the text matches the actual prompt.

✏️ Proposed fix
-        title={t("gamePage.meld.chooseAttackTarget")}
+        title={t(
+          waitingFor.type === "EntryAttackTargetChoice"
+            ? "gamePage.combat.chooseEntryAttackTarget"

… WaitingFor reach-guard

Two pinned census tests were failing at this lane's tip. Neither was caused by the
rebase; both were already red at the previous tip, and the first unfiltered run of
the engine suite is what surfaced them. Recording that plainly, because four review
rounds of narrow gates had all been green over a red suite.

`the_cr_603_5_prompt_census_is_pinned_so_a_sixth_producer_is_a_counted_event`
measured 39 against a pin of 38, with producers (5) and readers (8) both correct --
so the extra hit was a `#[cfg(test)]` line, 25 to 26. The site is a comment this lane
added in `journal CR 603.5 "may" answers`, which quoted the census needle verbatim
while explaining a producer's identity. That census has no comment filter; its only
exclusion is lines containing `..`. So the sentence counted itself.

The fix drops the opening brace from the quotation rather than moving the pin to 39.
Bumping would have recorded a comment as a census site permanently, which is the one
thing this instrument must never do -- it exists to count code. The test already
assembles its own needle with `format!` so that its source cannot match; prose that
names the construct owes the same care, and the comment now says so. Exactly one such
line exists in the crate and none upstream, so the class is closed, not sampled.

`exactly_two_waiting_for_variants_carry_a_decision_template_and_both_are_redacted`
measured 129 variants against a reach-guard pinned at 128. Upstream phase-rs#7336 ("make dig
entries attack") added `EntryAttackTargetChoice { player, object_id, valid_targets }`,
and the enum reads 129 at every tree involved -- the old upstream base, current
upstream, this lane before the rebase, and after -- so the pin had been stale since
before this work. It is updated with the variant named and with the fact that decides
whether the row's real assertion still holds: that variant carries no
`DecisionTemplate`, so it is not a third carrier. A reach-guard that is bumped without
that check stops guarding anything.

Verified: both tests pass, and `cargo probe-pin check` stays RC 0 -- which is not
incidental here, since the first fix edits a comment inside a census walk root and
`assert_count` counts raw substrings including comments.

…s new variant

Upstream phase-rs#7382 added `WaitingFor::EntryControllerChoice { player,
candidates }` (CR 614.12a), so the variant reach-guard moves 129 -> 130.

Adjudicated on the terms this row already set for phase-rs#7336, not bumped: that
variant's body holds no `DecisionTemplate`, so it is not a third carrier,
and both the carrier vec and the redaction loop below it are unchanged.
Only the reach-guard total moves.

The number is read from this assertion's own failure output rather than
from a hand-written variant counter -- one was tried and returned 49 while
contradicting itself, and a second instrument that disagrees with the syn
parse is worth less than no second instrument.

This drift produced no merge conflict and could not have, so the
reach-guard plus CI were the only things between it and shipping.
