The operator decided on 2026-09-23 to port the live fly onto the session framework in full.
New contract legacy-gameboy-v1: the profile gameboy-legacy-fafb-v783-v1, the proof that the
legacy f64 frame clock equals the rational one, the step-by-step placement of step_frame in
lockstep-v1, the readout context (location allowed and declared), the channels decision, the
memory-image inspection and ROM AssetRef, the environment (one no-button setup frame, u8->f32
audio, DC blocker at the edge, gameboy-slots-v1), the pokered-macros-v1 executor as one object
with its task, the legacy-ratchet-rollback-v1 policy, the composition digest carrying decoder
and macro-channel configuration, legacy-transient-reset restore semantics, sugar admission with
a one-commit lag, and FLYSIM01 as format of record until RETIRE-01. PROF-02b is a stub.
Dated amendments, each citing the decision, where earlier text kept the legacy loop outside
lockstep or had no place for it: workers-v1 (telemetry, Initialize, executor, episode request
kind, admission, new section 7 extension methods), step-v1 (rollback edge, Phase B/C, clock,
episode policy, sugar lag), state-media-v1 (audio, memory-image retention, restore semantics,
format of record, section 7 ratchet), README section 4, implementation.md (AGENT-01 and ENV-01
unblocked), the MaleCNS backlog (FOUNDATION-02 split, RUNTIME-01 contract) and analysis (5.2,
5.4), and readout.md (where the location comes from).
Two specifications CONTRACT-01 owes the slices that cannot be built without them.
seed-derivation-v1: the versioned derivation of independent per-agent seeds from a recorded
master seed and stable agent ids, the exact hashed material, the lane rule that keeps a seed
away from zero (the pinned kernel RNG is an xorshift, whose state must not be zero), the
properties a composition may rely on, and the test vectors both languages reproduce.
checkpoint-envelope-v1: the exact byte layout of the new envelope per state-media-v1 section
4, with the header, canonical-JSON manifest, 112-byte payload table entries, eight-byte
aligned payloads and the digest footer; the manifest field set; what a reader enforces and in
what order; and the durable commit sequence of section 6, whose commit point is the store
manifest rename. FLYSIM01 is unchanged, refused at the magic, and stays separately readable.
Both are specifications with fixtures, not the store: generations, rotation, the capture
queue and the restore flow remain STATE-01.
bus-conformance.md audits the flybus crate against bus-v1 sections 2 to 11, one
row per normative sentence: requirement, status, code location, the test that
proves it. 195 rows, 177 conforming, 10 deviating with the sentence that allows
each, 1 must-fix (the teardown starvation, fixed in this branch) and 7 not
implemented with an owner named. It also maps every BUS-01/02/03 acceptance
bullet to its test, reconciles all ten of the crate's own differences from the
draft, records the frame measurement with the reasons it is not a capacity
claim, and lists the two contradictions inside the draft it will not guess at:
the per-client queued byte budget against the latest-mode guarantee, and
section 2's call budget against section 6's client-owned deadline. Neither
changed any code.
bus-v1 gains section 12: dated amendments for the three error codes the
implementation needs and the draft left unnamed (CONFLICT, NO_TOPIC,
ARTIFACT_MISMATCH), one line of reason each, and for the one operation it adds
(rpc.responder.release), which is how bounded call correlation ends when a
handler keeps reply authority after releasing the request delivery. Section 9's
error list is inclusive, and section 4 already provides for a digest change.
The crate README points at the report, carries the new measurement summary in
place of the old numbers, and describes the two new test files; the design index
and the flybus index point at the report too.
