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.

Final review-impl

Final review-impl PASS head=6abccc55424cdb1d4f5cffa86de542572dfae040

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::BasePower leaf and its exhaustive readers are the reusable CR 208 power-axis support required by this card class.

Validation Failures

The local environment terminated rustc with SIGTERM during the engine compilation used by cargo check, cargo clippy-strict, the focused integration test, cargo coverage, cargo semantic-audit, and ./scripts/gen-card-data.sh; no Rust compiler diagnostics were emitted. CI should rerun the complete required suite.

CI Failures

None observed locally; CI checks were not yet available when this PR was opened.

Adds combat tests for counter assignment based on the power difference and for the unmodified sovereign case.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 126a8

This change adds a trigger that applies counters based on each creature’s current-versus-base power difference. The current implementation may misidentify that difference in some parsed conditions, while the tests do not cover all repeated recipients, so affected creatures could receive incorrect counters or be skipped; required engine validation also remains incomplete. Merge should wait for the bounded correctness and validation gaps to be addressed or explicitly accepted.

5951-5959: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Separate BasePower from live ObjectPt reads.

QuantityRef::BasePower resolves obj.base_power, but feeds() treats every ObjectCounters write as feeding ObjectPt. Counters apply in CR 613.4c and do not change base power under CR 208.4b, so this produces false ordering conflicts and prevents auto-ordering for commuting abilities. Use a distinct base-power read kind or refine the feed matrix, and add a regression test with a base-power reader and counter writer.

Correct the CR annotation for QuantityRef::BasePower.

Line 1225 adds BasePower under CR 208.1 / CR 209.1. CR 209.1 defines planeswalker loyalty. It does not describe toughness or base power. CR 208.4b defines current base power and toughness, and CR 613.4b places references to base power and toughness in layer 7b. (media.wizards.com)

Replace the inherited citation with a description that explains the BasePower classification and its pre-layer-7c semantics.

Proposed annotation
-        // CR 208.1 / CR 209.1.
+        // CR 208.1 / CR 208.4b / CR 613.4b:

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Do not bind the difference from a recursive property-presence scan.

filter_has_power_exceeds_base treats Not { PowerExceedsBase } and any Or branch containing PowerExceedsBase as a match. The function then binds Power - BasePower for recipients that the comparison did not select.

Carry an explicit comparison-derived difference binding from the parser. Do not reconstruct it from an arbitrary TargetFilter tree.

Test more than one eligible creature.

This test has one pumped member. It does not prove that repeat_for rebinds the recipient and quantity operands on a second iteration.

Add a second pumped creature with a different power-base-power difference. Assert the final counter count for both creatures. A regression that resolves only the first member will otherwise pass.

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.

Assert the attacking sovereign result.

Base-Form Anthem and Power Anthem also make sovereign 7/4 with base power 4. The current assertion checks only layered_creature. If the runtime omits the trigger source from the repeated recipients, this test still passes although every qualifying creature must receive counters. Assert that plus_one_counters(&runner, sovereign) equals 3.

As per path instructions: “Test adequacy is the highest-frequency contributor finding — scrutinize it.”

Suggested assertion
     assert_eq!(
         plus_one_counters(&runner, layered_creature),
         3,
         "current power 7 minus layer-7b base power 4 must add three counters, not six from printed power 1"
     );
+    assert_eq!(plus_one_counters(&runner, sovereign), 3);
