+### 28.28 Pinecone S2 resets its ATK ramp on deployment — `kits/ops/chess_char_3_10-pinecn.js`

+- Cause: the kit selected its ATK step from `SkillRuntime.activations`, which counts all activations in the battle;
+  the first cast after automatic redeployment therefore used a later step.
+- Source: [PRTS 松果](https://prts.wiki/w/松果), S2 备注: the count starts from this deployment. Rank-4/rank-7 steps
+  come from `data/chess.json` skill blackboards. The mode's redeployment/carry-state rules do not preserve this count.
+- A unit-local S2 counter is cleared in her existing deploy hook. Growth within one deployment and the fourth-step
+  cap remain; S1, range, trigger, talent and the global cumulative activation sequence are unchanged. No new
+  [ASSUMED] rule. This touches only Pinecone's kit, not 凛冬's separate deployment lifecycle (issue #315).
+- Regression: `test/content/kits_pinecn.test.js`, normal, elite without module and elite RPR-X; ramp/cap, later
+  paid redeployment, natural enemy knock-out and two copies with independent counters. These are model tests.
