A missing hash is unambiguously a malformed RPC payload; failing fast gives callers a precise diagnosis and removes the is-not-null plumbing further down the handler. - Source-gen the SSZ-REST error JSON via a registered SszErrorResponse record. Drops the anonymous-type allocation + reflection serializer on every error response. - Drop dst.Clear() in EncodeNewPayloadWithWitnessResponse (every byte in [0, totalLen) is overwritten by the encoder) and fold the now-dead Content-Type check in NewPayloadWithWitnessSszHandler (SszMiddleware validates application/json upstream before dispatch). - Switch fully-qualified BinaryPrimitives calls to a using import. - Re-order Proxy_storage_slot_writes_and_reads_are_recorded and Proxy_GetCode_records_bytecode_in_Witness_Codes tests to call BuildWitness before Disarm, matching the production order inside WitnessCaptureSession.Drain.

Each thrown exception left a TCS in the _pending dictionary indefinitely — a slow leak under any condition that can blow up the inner handler. Wrap the call in try/catch that disarms before re-throwing. Defensive: reorder WitnessCapturingWorldStateProxy.Disarm to flip the armed flag before nulling the tracking dictionaries. The current usage is single-threaded so this only matters under a hypothetical concurrent recorder, but the cost is zero and the intent reads cleaner.

The BranchProcessor only sees one optional witness dependency (the proxy via the existing decorator cast) instead of two (separate registry param + proxy cast). WitnessCapturingMainProcessingModule no longer takes a bool flag; it takes ISpecProvider via DI and decides internally whether to install the decorator based on the final spec's IsEip7928Enabled.

The type check in BuildRoutes filters by the concrete handler type so the same instance isn't dispatched twice. SszMiddlewareConfigurer registers the handler under both the concrete type and the ISszEndpointHandler interface, sharing one singleton. - Collapse multi-line `if (_logger.IsX)` blocks to one-liners consistent with the rest of the codebase. - Remove the SSZ Union[None, T] explainer comment in SszWireTypes; the SszCodec function names already document where the hand-rolled codec lives. - Add a one-line note on NewPayloadWithWitnessSszHandler explaining why this is the only endpoint that mixes JSON request + SSZ response (execution-apis#773).

Per-block arm/drain now lives in ProcessOne, leaving BranchProcessor witness-agnostic (reverted to its master shape). - Fold IWitnessCaptureRegistry into WitnessCapturingWorldStateProxy. The proxy now owns the cross-thread rendezvous (ConcurrentDictionary) alongside the IWorldState decoration; one class, one DI registration. - Capture parent state root at session construction (via proxy.InnerStateRoot) so Drain no longer needs a BlockHeader threaded from BranchProcessor. - TryArm bails out when the proxy is already armed, so a doubly-decorated IBlockProcessor (e.g. via test infra) doesn't NRE on nested arming. - WitnessProxyResolver: small holder that surfaces the inner-scope proxy to root-scope NewPayloadWithWitnessHandler (Autofac rejects null factory returns, so the nullable proxy needs a stable carrier). Tests: 60/60 witness, 1094/1094 merge plugin, 150/150 pyspec recreate.

It replaces the trie-read-interception approach, which forced execution off the flat-DB fast path (the flat snapshot layer and TrieNodeCache hand back decoded TrieNodes without materializing RLP). The walk mirrors `PatriciaTree.BulkSet` (partial-sort by nibble, bucketize into 16, recurse) and reuses its sort helpers. A recursion returns true when its whole subtree is deleted, which drives the lone-child collapse: when deletions reduce a branch to a single remaining child, the surviving sibling is reported even though it was never on a touched path — the node a plain read-path visitor misses. An optional top-level 16-way parallel mode fans the root subtrees out (children pre-resolved single-threaded so the root is never mutated concurrently); the sink must then be thread-safe. Output goes to a small `IWitnessNodeSink`. Tests assert, across fuzz seeds, BulkSet-derived shapes, and targeted collapse/extension/absent/mixed cases: - the generated node set (sequential and parallel) equals the ground truth obtained by replaying the reads and deletes through a read-capturing store; - the witness alone serves every read and recomputes the post-state root with no missing node. A benchmark compares the new generator against the old capture-during-mutation path; the new path is ~0.3-0.7x of the old time, with the biggest win on delete-heavy workloads. Scope: standalone class + tests + benchmark; not yet wired into the witness pipeline.

Intercepting every trie read forced execution onto the slow trie path and defeated the flat DB. - The env factory no longer wraps execution in WitnessCapturingTrieStore, so execution runs on the plain read path. - WitnessGeneratingWorldState.GetWitness walks the pre-state state trie once for the touched accounts, then each touched account's pre-state storage trie for its touched slots, collecting the witness nodes (including the deletion-collapse siblings the generator reasons about). Read vs Delete is read off the committed post-state: an account that no longer exists, or a slot now zero, was removed. - Removes the now-dead WitnessCapturingTrieStore and MultiAccountProofCollector. The generator runs with parallelism off (the collecting sink is a plain dictionary).
