It also supports per-target cardinality, dependent targets, strict trailing-input validation, and heterogeneous exile choices. Parser and integration tests cover these behaviors.

- Around line 4996-4997: Add a CR 608.2c annotation to
parse_contextual_bare_card_aggregate at the Mill/DealDamage rebinding arm,
alongside the existing CR 109.5 and CR 115.10 annotation, matching the citation
used by TrackedSetAggregate.
In `@crates/engine/src/parser/oracle_effect/mod.rs`:
- Around line 27663-27682: Update classify_latest_bare_card_publisher_in_ability
to classify def.effect and combine it with the recursive sub-ability result
before comparing against alternate. Preserve a shared producer only when both
branches classify identically, return TerminalUnsupported for a producer on only
one branch or differing producers, and return None when both branches have no
producer; use an exhaustive match instead of a wildcard.
In `@crates/engine/src/parser/oracle_nom/quantity.rs`:
- Around line 1641-1655: The parse_contextual_bare_card_aggregate_ref function
currently requires the entire remaining input to be the aggregate reference, so
trailing clause text prevents valid typed aggregates from parsing. Isolate the
aggregate quantity at the current clause boundary and consume its delimiter
before continuing, preserving terminal parsing and enabling both
parse_life_equal_quantity and damage-to/equal-to paths; add tests for terminal
and continuation pipeline cases.

Request changes — the current head has two parser-correctness gaps that can misbind or reject valid those cards aggregate chains.
🔴 Blocker
-
crates/engine/src/parser/oracle_effect/mod.rs:27663classifies onlysub_abilityfor the conditional's if branch before comparing it withelse_ability; it does not includedef.effect. A branch whose own effect isMill,Discard, orDiscardCardcan therefore be compared asNoneagainst a chain-set-compatible else branch and becomeTerminalUnsupported. The reverse clause scan then prevents a prior legitimate card-set publisher from binding a laterthose cardsaggregate. Fold the if branch's own publisher classification into the recursive sub-result before the branch comparison, preserveNonewhen both branches have no publisher, and use an exhaustive match for the remaining cases. CodeRabbit's current-head finding identifies the same path. -
crates/engine/src/parser/oracle_effect/lower.rs:7925andcrates/engine/src/parser/oracle_effect/imperative.rs:785accept the contextual aggregate only whenrest.trim().is_empty(). These consumers receive clause continuation text, so a valid aggregate followed by, then ...is rejected rather than returning its typed quantity and letting the chain parser continue. Bound the aggregate at the clause delimiter and add both terminal and continuation pipeline coverage for the life-equal and damage-equal paths. CodeRabbit's current-head finding identifies the same gap.
✅ Clean
The three Draw target-context changes were independently checked on this head and match their existing target-context plumbing; they are not part of this request.
Recommendation: fix both aggregate-chain paths and add discriminating terminal/continuation tests, then request re-review on the new head.

Approved on current head 746dc6c7f396d7e9ca066c543ccb30c7a2e861fe: the typed ChainSet source is selected at effect-chain assembly, the prior conditional-publisher and continuation cases are covered, and the Palantír/Gearhulk scenario tests drive the decline path through resolution with exact aggregate totals.
2 participants
Summary
Adds generic typed support for aggregate quantities over the immediately preceding milled/discarded card set, completing Palantír of Orthanc and Combustible Gearhulk without card-name dispatch. It also preserves the chosen opponent through optional-decline branches while keeping explicit each-player scopes intact.

9c4871154a29a6f8aceefc18856225afb362dc4b.Scope Expansion
None. The change stays within generic ChainSet aggregate parsing and typed scoped-recipient rewriting; it adds no card-name logic, protocol changes, or TriggeringBatch fallback.
Validation Failures
None.
CI Failures
None known. Fresh upstream CI will validate the exact pushed head.
