Summary

Preserves the existing typed HasAdventure filter when Oracle text uses a relative clause such as “that has an Adventure.” This fixes Garenbrig Squire’s trigger class and the shared target/spell-filter seam for the affected cards.

Claimed parse impact

Garenbrig Squire; Edgewall Innkeeper; Wandermare; Edgewall Inn.

Scope Expansion

None.

Validation Failures

The environment repeatedly terminated the phase-engine rustc process with SIGTERM and no compiler diagnostics during bootstrap, targeted integration test, card-data regeneration, and semantic-audit attempts. The source-level Gate A check and formatting/diff checks passed; full runtime/card-data validation is left to CI.

CI Failures

None — CI was not run locally; PR CI is pending.

Selected candidate and priority

Selected card: Garenbrig Squire.
Root-cause class: category 1, “Relative-clause / filter restriction on target dropped.”
Hermit of the Natterknolls was rejected after fresh live coverage showed its timing clause already parsed correctly. Garenbrig Squire remained a fresh misparse in the higher-priority misparse tier and shared an existing typed Adventure-filter seam; it therefore outranked open-issue and coverage-gap candidates.

Summary by CodeRabbit

  • New Features

    • Added support for “that has an adventure” and “that have an adventure” qualifiers when parsing card text.
    • Improved phrase matching to reject partial terms such as “adventures,” resulting in more accurate interpretation of card text.
    • Other relative-clause parsing behavior remains unchanged.
  • Tests

    • Added coverage for both supported grammatical forms and invalid longer variants.

📝 Walkthrough

Walkthrough

The parser recognizes “that has an adventure” and “that have an adventure” clauses. Valid clauses map to FilterProp::HasAdventure. Partial matches such as “adventures” are rejected.

Changes

Adventure clause support

Layer / File(s) Summary
Adventure relative-clause parsing and validation
crates/engine/src/parser/oracle_target.rs, crates/engine/src/parser/oracle_trigger.rs
The parsers recognize singular and plural Adventure clauses, require full consumption and a word boundary after “adventure”, and return a typed HasAdventure filter. Tests cover valid forms and reject “adventures”.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 775de

This is a localized parser fix that preserves typed Adventure filtering for affected card text and adds targeted coverage; no actionable merge-blocking risk remains at the current head after normal CI checks.

Changes requested — current head 9c2dee1342f77395e016f14a9e32f4d4978894c0.

Please rebase this branch onto current main and preserve the intervening mainline work. The merge base is 308f4f27164d408dcd68c7423565d9d65f878f33, while the PR base 7514e8f758ee59f25f7652f9bafd5da1af230f9a is two commits ahead. As a result, the PR diff currently reverts unrelated changes, including crates/engine/src/game/effects/mod.rs's deferred RevealedHasCardType result-object condition and deletes crates/engine/tests/integration/archdruids_charm_search_destination.rs.

The old 7d066870 CI failure was the integration fixture's mutable-borrow error; 9c2dee changes that fixture, but its required CI is still pending and no current-head <!-- coverage-parse-diff --> exists for this parser change. Rebase, let current CI and parse-diff complete, then request re-review.

Changes requested — current head 13b4a9cc077532d7d03ee593e957d117eb63af45.

parse_post_spell_modifier now delegates every complete that … spell qualifier to the shared relative-clause parser (crates/engine/src/parser/oracle_trigger.rs:17079-17090), rather than accepting only the Adventure wording. The available parse-diff (currently bound to ancestor 19474c8736a24098ec0dcada1eabbe38054c5557, so not valid current-head evidence) reports 33 cards changed: beyond the three Adventure triggers, it changes fourteen that targets … SpellCast filters and several other trigger/ability/static filters.

Either narrow this PR to the named Adventure qualifier, or explicitly retain the general dispatch and provide representative production-path regression coverage for the newly accepted non-Adventure modifier classes, with a regenerated <!-- coverage-parse-diff --> bound to this exact head. The present unit test and Garenbrig Squire scenario cover only HasAdventure (oracle_target.rs:7035-7055; garenbrig_squire_adventure_trigger.rs:17-54), so they do not discriminate the other changed card classes.

The remaining CI job is pending; that is not this request's blocker.

Changes requested - current head 5335900e5456d268a22dd1a11bf6e01c46b8618a.

parse_post_spell_modifier still sends every complete that ... spell suffix through the shared relative-clause parser at crates/engine/src/parser/oracle_trigger.rs:17079-17090; it is not limited to the Adventure wording in this PR. The SHA-bound parse receipt reports 33 changed cards / 16 signatures: beyond the three Adventure triggers, it changes 14 that targets ... SpellCast filters, targets only ... filters (including Leyline and Zada), and non-SpellCast target filters. The new tests cover only HasAdventure (crates/engine/src/parser/oracle_target.rs:7035-7055, crates/engine/tests/integration/garenbrig_squire_adventure_trigger.rs:17-54), so they do not establish that broader behavior.

The broad rewrite is also currently red: required shard 4 fails trigger_leyline_of_resonance_targets_only_single_creature_you_control at crates/engine/src/parser/oracle_trigger_tests.rs:18509 and trigger_zada_targets_only_self at :18412, each receiving a new And filter where the established test expects the prior Or structure.

Please either narrow this PR to the that has/have an Adventure qualifier and its three-card scope, or explicitly keep the general parser change with updated affected assertions plus representative production-path regressions for every newly accepted qualifier class. Re-run current CI and retain a SHA-bound parse receipt after that scope decision.

7721-7743: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Correct boundary-guarded Adventure clause; add unit test coverage.

The word-boundary check correctly rejects "adventures" and "adventurer" while accepting "an adventure" for both "has "/"have " leads. The CR 715.2a citation is accurate: it matches the Comprehensive Rules text for "has an Adventure."

No unit test in this file's mod tests exercises HasAdventure (singular, plural, or the rejected "adventures" case). Add a targeted unit test for this arm, covering the affirmative/plural forms and the invalid longer spelling, at the parser-primitive level rather than relying only on card-level integration tests.

As per path instructions: "Test the shared parser primitive across affirmative/plural variants and invalid longer spellings, rather than testing only named cards."

Required: commit the scoped parser contract and restore CI

At 03ba6cd27012e02894e360b02d19aeea6bd0e36b, the previous broad that ... dispatch is resolved: parse_post_spell_modifier now recognizes only that has/have an adventure (crates/engine/src/parser/oracle_trigger.rs:17076-17096), and the current SHA-bound parse receipt is correspondingly limited to nine related Adventure effects.

The current implementation still has a required failure. Shard 4 fails parser::oracle_ir::snapshot_tests::edgewall_innkeeper: crates/engine/src/parser/oracle_ir/snapshots/engine__parser__oracle_ir__snapshot_tests__edgewall_innkeeper_ir.snap:31-38 still expects a creature-only filter, while the new parser correctly adds HasAdventure. Update the IR/lowered snapshot contract for this intentional behavior and get current CI green.

Also add focused parser-primitive coverage beside the existing parse_that_clause_suffix tests in crates/engine/src/parser/oracle_target.rs for singular and plural forms and the adventures word-boundary rejection. The integration/card effects do not discriminate that shared clause boundary.

Changes requested — current head 775dea90fe46fae3ecc621973916f693212e2743.

🔴 Blocker

crates/engine/src/parser/oracle_trigger.rs:17246-17259 now emits FilterProp::HasAdventure for spell-cast qualifiers, but the SpellCast evaluation path (crates/engine/src/game/triggers.rs:12607-12615crates/engine/src/game/filter.rs:4913-4917) evaluates that property against a snapshot and returns false. As a result, the newly parsed filters prevent the intended triggers for Garenbrig Squire, Edgewall Innkeeper, and Wandermare from ever firing. CR 715.2a was verified for this Adventure characteristic.

Please extend the runtime spell-record/cast-event authority so the predicate is evaluated from the cast spell’s relevant Adventure characteristics, then add a real cast-trigger regression for the positive Adventure case and a non-Adventure negative case. The parser-unit coverage is useful but cannot establish the runtime trigger behavior.

Recommendation: request changes; this needs the runtime authority and discriminating cast-pipeline tests, not a maintainer fixup.

Maintainer port in progress

Current head 410cf02d0d7a65594da44324b65dca94a8f01ced is a clean maintainer merge of current main, preserving the reviewed Adventure qualifier and its cast-record regression coverage. The prior implementation blocker is resolved; fresh required CI and the SHA-bound parse-diff receipt are now pending for this new head. I will complete approval and queue handling after those current-head artifacts settle.
