+- task: `WBV2-P5-002`
+- parent: `WBV2-P5-001`

+
+## Evidence
+
+- Blender desktop and WASM/Main expose the same compositor graph and four-strip sequencer timeline with stable frame ranges, media paths, muted audio and cross-transition dependencies.
+- The bounded compositor executes and hits its frame cache; sequencer frame resolution and cross transition are revision-bound, while stale edits are rejected.
+- Image codec probing is READY, audio runtime probing is explicitly BLOCKED when unavailable, and source hash drift cannot become a READY result.
+- Cancellation, quota/budget, restart and resource release are validated across render/compositor/media recovery records. Save/reopen and malformed blend checks preserve project state.
