An animation over a container aims its rows at template ids. Played on another container, those ids are not there, so every row below the root was skipped without a word. "Enemy - Hit" built over the Slime flashed the slime's Sprite but never the skeleton's. - When the template id is not found below the object, the runtime takes the names on the way to the row's target in the root and walks the same names below the object, level by level. - The id still comes first, so the root's own instances bind as before. - A name missing at some level, or taken twice, skips the row, as a gone target always did. - The rule is the pure function targetNamePath in animation.ts. The AnimationSystem only walks the children. Tests: - animation.test.ts: 84 tests, all green (+2). One plays over a second container built alike, renamed and with the name twice. The other names a row two containers deep. - Counter-check: with the name fallback off, the new runtime test fails (1 of 84). - Project cbbf160bb7e8 (revision 14407), Demo scene: "Enemy - Hit" and "Enemy - Die" change Flash and scale on the skeleton's Sprite. Without the fallback the skeleton stays unchanged. - The gate did not run before this commit. CI covers it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
