+## Evidence
+
+- Desktop and WASM/Main expose one deterministic performance receipt covering geometry 100K/1M/10M, 4K/8K textures, long media and simulation-cache byte limits.
+- OOM, storage quota, device-loss and network interruption cases are explicitly `BLOCKED` with zero published results; the old Main revision remains usable and cache state is quarantined.
+- Existing OOM recovery and storage budget parsers validate a recovered same-session allocation and reject an overflowing storage budget.
+- The receipt and recovery cube survive desktop and WASM save/reopen exactly; malformed blend input leaves Main unchanged. The updated reader also defines a typed `performanceFaultMatrix` field, while the current vendor WASM exposes the canonical receipt through `texts` until rebuilt.
