support for ObjectScope::OtherRevealedCard and ObjectScope::OwnedLinkedExileCard
while resolve_object_pt returns zero for them. Update those two mappings to
Unhandled, unless implementing the corresponding object lookups in
resolve_object_pt; leave the other BasePower scope mappings unchanged.
In `@crates/engine/src/game/quantity.rs`:
- Around line 1225-1227: Update the annotation for the QuantityRef::BasePower
branch to replace the inherited CR 208.1/209.1 citation with a verified CR
208.4b and CR 613.4b description covering current base power/toughness and

In `@crates/engine/src/parser/oracle_effect/mod.rs`:
- Around line 28182-28210: The current filter_has_power_exceeds_base scan
incorrectly binds the power difference for negated or partially matching filter
trees. Remove this property-presence-based binding and carry an explicit
comparison-derived difference from the parser into the binding logic, ensuring
the QuantityExpr::Difference is created only when the actual PowerExceedsBase
comparison selects the recipient.

- Around line 48-68: Extend the test around pumped and unpumped creature setup
to include a second pumped creature with a different power-minus-base-power

pumped creature and preserve the unpumped assertion. Ensure the assertions

- Line 18: Correct the rules citation in the module comment: replace the

Changes requested — BasePower does not observe layer-7b set effects.
🔴 Blocker
crates/engine/src/game/quantity.rs:3482-3489 resolves QuantityRef::BasePower from obj.base_power, but the layer pass only seeds obj.power from that baseline (crates/engine/src/game/layers.rs:2045-2048). Both fixed and dynamic layer-7b setters then write only obj.power (crates/engine/src/game/layers.rs:7715-7719 and 8080-8089), leaving obj.base_power at the printed value. Consequently, the new production-combat case at crates/engine/tests/integration/sovereign_okinec_ahau.rs:72-98 reads 1 rather than the current layer-7b base 4 and awards six counters instead of three.
Implement one authoritative current layer-7b base-power carrier for quantity/filter/LKI reads, so it is distinct from both printed P/T and the layer-7c-modified current power. Keep this real combat regression (base 4/4 plus +3/+0 on a printed 1/1) green; it must fail if BasePower falls back to printed power.
Recommendation: request changes — correct the layer evaluation authority, then retain and pass the discriminating combat regression.

Expect three counters for the second creature.
Base-Form Anthem applies to every P0 creature. It sets second_layered_creature to base power 4. Power Anthem then adds +3/+0, so its current power is 7. The difference is 7 - 4 = 3, not 5 - 4 = 1. Official CR 613.4b applies base-setting effects before CR 613.4c applies power/toughness modifiers and counters. (media.wizards.com)
If different differences are required, give this creature a distinct layer-7c modifier instead of relying on its printed 2/2 values.

Maintainer hold — current head fbd00fec22a0a4d6d6dddf7b6dfec3ea3d9d6769 contains the exhaustive-match repair. The preceding current-head CI failure omitted BasePower from QuantityRef::player_scope_mut. The one-line object-scope classification repair passed parser gates; fresh CI, SHA-bound parse evidence, CodeRabbit, and a completed current-head implementation review remain required. |

Correction: the current head is fbd00fe. This supersedes the abbreviated SHA typo in the preceding hold. The hold condition is unchanged: fresh CI, SHA-bound parse evidence, CodeRabbit, and completed current-head implementation review remain required. |

Changes requested — the otherwise branch can retain a zero-valued “the difference”.
🔴 Blocker
crates/engine/src/parser/oracle_effect/mod.rs:33367-33370 binds a comparison-derived difference through the clause effect and sub_ability, but omits else_ability. An Otherwise clause is held separately as ClauseDisposition::BranchOtherwise (crates/engine/src/parser/oracle_effect/mod.rs:31373-31382) and is attached only later in crates/engine/src/parser/oracle_effect/assembly.rs:1569-1615. By then its recursive parse has no enclosing comparison, so QuantityRef::Variable("difference") remains unbound and resolves through the generic named-choice fallback (crates/engine/src/game/quantity.rs:3589-3599) as zero. This contradicts the full-tree contract documented at mod.rs:28482-28502, which explicitly includes else_ability.
Bind the cloned else_def at the BranchOtherwise assembly seam, where the antecedent conditional is available, using the existing resolve_difference_anaphor_in_ability authority and that condition’s difference_expr. Add a parser/lowering regression for a comparison-gated Otherwise branch containing “equal to the difference”; assert the branch receives the typed QuantityExpr::Difference, never the Variable("difference") placeholder.
Recommendation: request changes — close this full-tree binding gap, then I can re-review the current head.

Summary
Adds parser, quantity-resolution, and runtime support for Sovereign Okinec Ahau's attack trigger: each creature whose current power exceeds its base power receives +1/+1 counters equal to that difference.

Claimed parse impact
Sovereign Okinec Ahau. The parser extension is class-level for controller-scoped creature populations with typed P/T properties; generated card-data comparison was unavailable because generation was interrupted during engine compilation.
Scope Expansion
None. No protected architecture path was touched. The new
QuantityRef::BasePowerleaf and its exhaustive readers are the reusable CR 208 power-axis support required by this card class.Validation Failures
The local environment terminated
