Fix Sauron, Dino Devotee — restore modal mode-body subject filtering - #7037
Conversation
…hase-rs#7031) The phase-rs#6811 native-IR modal rework threaded the trigger's ParseContext into mode bodies without the subject filtering the retired pre-IR path applied via derive_modal_subject. A SelfRef/Any trigger subject now leaked into every mode body, corrupting the subject-presence forks: - Sauron, Dino Devotee (the reported regression): the mode-body "It's a green Dinosaur with base power and toughness 5/5" copula clause fails closed — the honest-bind gate correctly refuses to animate the trigger source — and the whole payload drops to Unimplemented{name:"it's"}. At v0.35.2 it parsed to the full GenericEffect modification suite. - Disciple of Perdition (silent misbind, same commit): the mode-body "That player loses 1 life" fails open into LoseLife{TriggeringPlayer} instead of the targeted opponent's ParentTargetController. Restore the rule at the IR seam: mode_anaphor_subject clears a SelfRef/Any subject per mode inside parse_modal_mode_irs — the single production funnel all four modal forms share (bullet/inline triggered, spell, activated) — so mode-internal referents bind mode-body anaphors again (CR 608.2c/608.2k). Non-self subjects pass through unchanged; the chain-level anaphor rewrite layer is untouched and parse-time ParentTarget is a fixed point of its GenericEffect arm, so the already-correct class members (Arbalest Engineers, Ertai Resurrected, Riku of Many Paths) stay byte-identical. Full-pool parse diff: exactly {sauron dino devotee, disciple of perdition}; coverage -1 unsupported / -1 gap; semantic-audit clean. Tests: runtime discriminator + live ForAsLongAs{RecipientHasCounters} duration proof (reverted: (2,2) != (5,5)); no-legal-target CR 700.2b row; Disciple/Blizzard-Specter shape pair pinning the scope-rung precedence; four building-block arms incl. the object_pronoun_ref precedence pins; Arbalest pinned-green composition guard (documented non-discriminating); Grenzo/Riku/pip-boy retained-subject set stays green. The integration-card fixture regen (required for the new tests' keys) absorbed pre-existing staleness (added keys + refreshed stored parses; oracle text untouched) and enlarged the ordering-parity sweep corpus, surfacing arashin sovereign — adjudicated as a documented-conservative over-prompt (unprofiled PutOnTopOrBottom lands in the fail-closed RwProfile catch-all; members' writes are disjoint per CR 603.6c).

disciple_of_perdition_that_player_binds_to_targeted_opponent, resolving mode 2
after the creature dies and targeting an opponent’s graveyard. Assert the
targeted opponent loses exactly 1 life while the other player’s life total

output.

for the object_pronoun_ref pinned-object behavior, or omit the citation if the
rule does not fully support the claim; retain the valid intervening-if reference
separately.

Resolved: the anaphor comment now cites CR 608.2k, which governs a specific untargeted object previously referred to by the trigger condition; CR 603.4 was removed because it only defines the intervening-if timing check. The focused Disciple of Perdition runtime test covers the targeted opponent binding. |

Route the dies event through the production zone-change pipeline.
move_to_zone followed by manual process_triggers bypasses replacement-aware ProposedEvent::ZoneChange processing. A production regression in zone-change event construction or trigger delivery can leave this test green.
Submit the zone change through the standard engine application path. Then drive GameRunner through the resulting WaitingFor states.
As per path instructions, “Zone changes must route through the replacement-aware pipeline (ProposedEvent::ZoneChange)” and tests must drive the production pipeline.

CI Failures
phase-ailib testvelocity_score_projection_deadline_is_live_on_a_traversing_fixturefails on this machine at the PR head and at pristine base562e7b5d2(verified in a clean detached worktree) — a hardware-speed artifact: the test's reach-guard requires an uncapped projection to cost ≥20 ms and an Apple-Silicon dev machine completes the traversal under that threshold, so the arm cannot discriminate locally. Deferring to CI as the owner of this check; the local pre-push hook was bypassed for exactly this pre-existing failure after proving it at base. All engine-crate suites pass locally.Pipeline report
Plan-review loop: 3 rounds to CLEAN (round 1: 4 findings incl. re-scoping a non-discriminating test and reconciling the anaphor-rewrite layer; round 2: 2 audit-completeness findings, design verified; round 3: CLEAN). Implementation: 1 round + 1 scope-widened fix round (the parity ledger row). Implementation review: CLEAN at the committed head, with the reviewer independently re-running the discrimination experiment and adjudicating all 44 fixture parse refreshes.
