### Slice A2b detached finite object animation implemented (2026-07-20)
The `obj+0x2d0` consumer resolves `0x242(handle,flags)` as a finite-animation detachment control. Bit 0
makes that object's one-shot color/scale/rotation/translation/source-rectangle group ignore `0x243`'s
global force-complete request and prevents it from holding native blocking-presentation dirty state, while
leaving redraw dirty so it continues animating asynchronously. Native clears bit 0 after the finite group
finishes. SC0000's two CG loaders pass zero; 302 of 303 corpus calls do the same. The only value-one use is
an animated battle object in `BTL.BIN`.
`GfxState` now retains and clones the control word, excludes detached channels from blocking waits without
excluding them from visual recomposition, protects them from `0x243`, and clears bit 0 on natural completion.
The `0x243` model is correspondingly completed: it commits every unprotected finite channel as well as
resetting the separate global animation clock. Focused regressions cover get-or-create/clone behavior and
the protected-versus-ordinary completion split.
The canonical opcode source is refined and regenerated. EngineCtx adds the animation-service flags at
`0x51b80` and refines the two dirty-field roles; the expanded 76-field structure is reapplied to `/v2`.
The `0x242` handler/worker, `0x243`, and the shared channel consumer are named/commented and saved. SC0000
is now **122/129 distinct opcodes handled (94.6%)** and **16,039/16,257 instructions handled or safe-noop
(98.7%)**. Its remaining seven gaps total 218 instructions, 206 of them the deferred shared-profile write.
**Next:** investigate the four adjacent one-call unknowns `0x19b`, `0x19c`, `0x1ca`, and `0xae` together
before choosing an implementation. Their low frequency makes a shared native-service relationship more
important than any one opcode's count; persistence-bound `0x1a2`, `0x1ad`, and `0x1cb` remain deferred.
Validation: all 211 engine tests pass; opcode and EngineCtx tests/lints, vm0 RECOVER, the zero-warning
Godot build, threaded self-test, and `git diff --check` are clean.
