The contributor's code (render/spine.js syncFormPose, the render/units.js wiring and FORMS entry, the headless
test/render/forms.test.js block), applied from PR #365, so they are the author of this commit. Maintainer side: the
hard-coded Spine id became a STEALTH_FORMS table (form while the stealth bit is off), comments and docs/ASSETS.md
reworded. Not ported: the PR's sim targeting rewrite (content/enemies/invisible.js), its enemies_bosses tests, its
roster.json and the Chrome suite (forms.browser.test.js, not run here).
Seen (#296, FrogThai): a blocked 骨刺 kept the snake. The sim already sends UF.STEALTH only while its 隐匿 is effective
(not blocked, not revealed — targeting.js enemyStealthed); the view now keys the FORMS 'revealed' clip set (Idle_B /
Move_B / Die_B / Attack_B, all in the skeleton) off that bit in UnitView.sync — before a DIE of the same snapshot — and
re-poses at once: a running attack continues in the other attack clip at the same point relative to its strike frame
(Attack_A hit 0.533 s, Attack_B 0.733 s; a pending wind-up still strikes on time), a stun / idle restarts on the new set
without a crossfade, and a frozen skeleton is posed with update(0); a model loaded later is posed the same way.
Golden: unchanged (render only).
