fix(engine): scope damage-amount thresholds to the whole damage event - #7476
Merged
Conversation
Innocent Bystander ("Whenever this creature is dealt 3 or more damage")
must fire once when 3+ damage arrives in a single damage event from any
number of sources. The threshold check previously read one event's
amount, so it under-fired on split damage and would over-fire per source
if naively widened.
Adds a DamageAmountScope { PerSource, WholeEvent } axis on
DamageAmountThreshold. The received-damage grammar defaults to
WholeEvent; a "by a single source" tail (Pain Magnification) narrows it
to PerSource. Source-led and subject-led DamageDone triggers stay
PerSource by construction.
CR 120.4 + CR 120.4b: damage is processed in one four-part sequence over
a single damage event, and abilities that trigger when damage is dealt
trigger at that granularity. Innocent Bystander's ruling is explicit that
the damage must arrive "all at once".
NOT YET COMPILED OR TESTED - see the run record for the enumerated
deferred verification obligations.

Addresses impl-review-r1. H1 - rustfmt: restore the oracle_trigger.rs import layout (the reflow put a line at exactly 100 chars, which rustfmt's import tactic rejects under the pinned nightly), put deserialize_damage_amount_compat's signature on one line, and split four assert_eq! first-arg/value pairs. M1 - CR 120.9 carried a claim it does not make at seven sites. CR 120.9 governs what an EFFECT's "the damage dealt" back-reference resolves to, not how a trigger's amount threshold is scoped; the diff said so in three disclaimers while citing 120.9 as authority for the opposite. Re-cited to CR 120.4 / CR 120.4b. One site was a straight substitution error: the base read "CR 603.2: an ability triggers when a game event matches ITS trigger event", which is CR 603.2 verbatim, and only the number had been swapped. M2 - the settlement skip gate keyed on trig_def.batched while its sibling gate and the MatchedTrigger carrier moved to fires_once_per_batch. Aligned. Behavior-neutral: unreachable today because settlement carries only ZoneChanged occurrences, but the two gates must not drift apart. M3 - the carrier comment claimed one consumer; there are eight. Enumerated them with the reason all eight are safe for this axis today. Also folds in a comment correction the executor raised after the checkpoint: damage_received_aggregates_whole_event is the only production read that BRANCHES ON the scope, but is_per_source_damage_scope reads it too via a non-exhaustive matches!, so a third variant would not fail to compile there. STILL NOT COMPILED OR TESTED. (cherry picked from commit 0c7ada1516a4d145c6fd7bcaa7350891a3a6add5)
The previous fix round replaced a wrong CR number (120.9) with a differently wrong one: it cited CR 120.4b as the authority for "the threshold reads that source's share and never aggregates across simultaneous sources". CR 120.4b is the whole-event rule. It says damage is dealt and that abilities which trigger on damage trigger at that point; it draws no distinction between one damaging source and several, and says nothing about how a threshold's aggregation domain is scoped. The tell was internal: the same number was cited as authority for both poles of the axis - "the batch summed" at triggers.rs and "never aggregates" here. One rule cannot license both. The per-source pole follows from trigger-event matching instead. CR 603.2: an ability triggers when a game event matches its trigger event, and the source-led grammar names its source, so the event it matches is one source's damage. CR 603.2c carries the repeated-firing half - an ability "can trigger repeatedly if one event contains multiple occurrences" - which is what makes two qualifying sources in one damage event fire Pain Magnification twice rather than once on the sum. Also widen the batched-firing gate comment in triggers.rs to justify both collections it covers. skips_batched_definitions() matches Segment | Settlement, but the comment reasoned only about settlement. Segments are built solely by append_and_collect_logical_zone_trigger_segment, which filters events to ZoneChanged before collecting, and settlement replays those same filtered occurrences, so no DamageDealt event reaches either and the skip is inert on both paths today. Comment-only; no behavior change. (cherry picked from commit e7b3b9829cb9f8aeec72fd453312f4e266a34e8d)
The previous round re-cited this header to `CR 603.2c + CR 120.4b` and in
doing so deleted `CR 120.4` - which was the number carrying the
proposition the header goes on to assert.
CR 120.4b is a timing rule: damage is dealt, and abilities that trigger
on damage trigger at that point. It says nothing about multiple sources
and does not name a whole-event default. CR 120.4 does: damage is
processed in one four-part sequence over a single damage event, and the
worked example printed under CR 120.4d states a multi-source event as one
bracketed entry ("[10 damage is dealt to the defending player]" for two
unblocked 5/5s).
The artifact's own canonical doc at types/ability.rs:4066 already splits
the work correctly, with "then" marking the handoff: CR 120.4 establishes
the granularity, CR 120.4b then puts damage triggers at it. Four other
sites repeat that split. This header had become the only place asserting
the whole-event proposition without CR 120.4.
The CR 603.2c half is kept - it is the right rule for the two-attackers
row, where one damage event containing two qualifying occurrences fires
the ability twice rather than once on the sum.
Also name the referent in the triggers.rs batched-firing gate comment.
Widening that paragraph to cover both collections left "the two" sitting
after three sentences about Segment and Settlement, when the invariant it
protects is agreement between this gate and the carrier below.
Comment-only; no behavior change.

Preserve the legacy tuple format during rolling deploys. No frontend or tooling consumer reads damage_amount positionally. Persisted GameState includes GameObject.trigger_definitions, so the new object form can reach older engine builds that accept only the tuple form. Emit the tuple for PerSource, or drain older readers before enabling object writes.

…hase-rs#7479) phase-rs#7476 gave `damage_amount` a scope axis and added a compatibility deserializer, so data written before the axis still loads. The migration was one-way: nothing preserved the write side. `PerSource` serialized as `{"comparator":"GE","threshold":6}` where every build predating the axis emits and expects `["GE", 6]`. Eliding the `PerSource` default keeps the object minimal but does not preserve its shape, so two comments claiming pre-axis cards "serialize byte-identically" were false - the assertion 15 lines below one of them pinned the object form. This matters because the shape reaches persistence with no version gate to reject it early. `PersistedSession.state` is a `PersistedGameState` (server-core/src/persist.rs:23) and `GameObject.trigger_definitions` is serialized, so a build carrying the axis writes rows that an older build fails to deserialize - taking the whole session restore with it. The three consumers are the ones already named on `deserialize_damage_amount_compat`: browser IndexedDB saved games, the phase-server session store, and the shared card fixture. `serialize_damage_amount_compat` is the write-side counterpart. PerSource emits the legacy tuple; only WholeEvent emits the object, and no pre-axis reader can represent that pole anyway. Information-lossless, and it makes the byte-identical claim true rather than deleting it. Modeled on the `serialize_multi_target_min` / `deserialize_multi_target_min` pair in the same file, which collapses a Fixed variant to a bare int the same way. Also pins `#[serde(default)]` on `DamageAmountThreshold::scope` with an object row carrying no `scope` key. That shape is reachable, not hypothetical: any build between the axis landing and this serializer wrote exactly it. Reported by CodeRabbit on phase-rs#7476, which merged before the finding could be addressed in that PR. Co-authored-by: matthewevans <matthewevans@users.noreply.github.com>

What
Adds a
DamageAmountScope { PerSource, WholeEvent }axis to damage-amount triggerthresholds, so a received-damage trigger with no source scoping reads the whole
simultaneous damage event rather than one source's share.
This makes Innocent Bystander ("Whenever this creature is dealt 3 or more damage,
create a Clue token") fire once when 3+ damage arrives in a single damage event
from any number of sources. Previously the threshold was checked against one event's
amount, which under-fired on split damage; naively widening it would have over-firedonce per damaging source.
Why the axis, rather than just widening the check
The two poles are both real, and which one applies is grammatical:
"is dealt N or more damage"(received, unscoped)WholeEvent"is dealt N or more damage **by a single source**"PerSource"<source> deals N or more damage"(source-led)PerSourceThe
"…by a single source"tail narrows the aggregation domain from the grammar'sdefault back to one source. Source-led and subject-led
DamageDoneforms stayPerSource— the grammar names its source, so the trigger event it matches is thatsource's damage.
Both poles are constructed explicitly at their parser sites rather than relying on
DamageAmountScope's#[default], so no exit can silently fall back to the wrong pole,and each is pinned by a test.
Rules grounding
simultaneously is one event. CR 120.4d's worked examples state a multi-source event as
a single bracketed entry ("[10 damage is dealt to the defending player]" for two
unblocked 5/5s), which is the whole-event reading.
source-led grammar names its source, so the event it matches is one source's damage.
