+## Title
+
+Adopt row-based 7x8 sprite animation semantics with backward-compatible state aliases.
+
+## Severity
+
+P2
+
+## Summary
+
+Standardize `sprite.png` packs so each of the 7 rows maps to semantic animation groups, while
+keeping runtime compatibility with existing state names (`active`, `success`, `error`).
+
+## Scope
+
+- `assets/sprite-packs/{default,ferris,demogorgon}/manifest.json`
+- `crates/sprimo-runtime-core/src/lib.rs`
+- `crates/sprimo-app/src/main.rs`
+- docs:

+- row 2 (`8..15`): `happy`, `love`, alias `active`
+- row 3 (`16..23`): `excited`, `celebrate`, alias `success`

+- row 5 (`32..39`): `working`
+- row 6 (`40..47`): `angry`, `surprised`, `shy`, alias `error`
+- row 7 (`48..55`): `dragging`
+
+One-shot defaults:
+
+- `celebrate` and `success`: one-shot
+- all others: loop
+
+## Implementation Notes
+
+1. Runtime state mapping updated:
+- `Dragging` now maps to `"dragging"` instead of `"idle"` in runtime-core and Bevy frontend.
+2. All bundled sprite-pack manifests now expose row-based names and compatibility aliases.
+3. Added runtime-core unit test to confirm `SetState::Dragging` selects `"dragging"`.
+4. Updated schema/design docs to formalize the row convention.
+
+## Verification
+
+### Commands Run
+
+- [x] `cargo test -p sprimo-runtime-core`
+- [x] `cargo check -p sprimo-tauri`
+- [x] `cargo check -p sprimo-app`
+
+### Result
+
+- Status: `Fix Implemented`
+- Notes: packaged runtime visual verification pending.
