Recorded protocol

RECORDED · corpus-ipc wire v1

IPC provenance you can check byte for byte.

These are recorded corpus-ipc wire-v1 envelopes, replayed offline from checked-in files. ZeroMQ, the Axum IPC service, and any live transport stay out of the browser. With JavaScript, the page decodes each envelope through the Rust/WASM adapter crate behind the homepage demo, in its labs build.

Wire v1 fixtures

Stimuli, spikes, and eligibility traces from one replayed tick.

IpcMessage::Stimuli

kinetic-seed9-step7-stimuli

Derived from a deterministic adapter replay, not captured from hardware or a live service. values are the 16 clamped kinetic-signals features the adapter handed to axon-encoder for completed step 7 of the committed contract-5 golden (seed 9). batch_id is assigned (2^53 + 1); timestamp is 0 because replay has no wall clock.

Not decoded yet. The bytes above are the reference; the browser view decodes them through the Rust/WASM adapter when JavaScript and WebAssembly are available.

IpcMessage::Spikes

kinetic-seed9-step7-spikes

Derived from the same replay, not captured from hardware or a live service. Each event is a neuromod LIF spike emitted at completed step 7: channel is the neuron index and time is the step. strength 1.0 marks a binary spike; the adapter does not export spike amplitude.

IpcMessage::EligibilityTraces

kinetic-seed9-step7-eligibility-traces

Derived from the same replay, not captured from hardware or a live service. Rows are neuromod's per-synapse eligibility traces for LIF neuron 0's 16 input channels after completed step 7; last_spike_time is that neuron's neuromod step of its most recent spike.

Fail closed

Every rejection has a stable reason.

Adapter reason codes
Code Meaning
expected-variant-unsupported The declared variant is not Stimuli, Spikes, or EligibilityTraces.
expected-digest-invalid The out-of-band SHA-256 is not 64 lowercase hex characters.
oversize The bytes exceed the pre-parse limit; nothing is hashed or parsed.
digest-mismatch SHA-256 over the exact bytes differs from the out-of-band digest.
malformed-json The bytes are not one syntactically valid JSON document.
envelope-not-object The document is not a JSON object (for example legacy "Ping").
wire-version-missing No wire_version. Legacy unversioned JSON is not accepted here.
wire-version-null wire_version is null.
wire-version-duplicate wire_version appears more than once.
wire-version-invalid wire_version is not a non-negative integer that fits u32.
wire-version-too-old wire_version is below the oldest version corpus-ipc supports.
wire-version-too-new wire_version is newer than corpus-ipc understands.
payload-missing No payload after the version check.
payload-null payload is null.
payload-duplicate payload appears more than once.
unknown-variant The payload names an IpcMessage variant corpus-ipc does not define.
invalid-typed-data The payload does not match the typed corpus-ipc schema.
validation-failed corpus-ipc validation rejected the payload (finite values, limits, lengths, unique ids).
kind-mismatch The decoded variant differs from the declared one.
canonical-encoding-failed corpus-ipc could not re-encode the accepted envelope.
