Review round 1. The sizing amendment's worst case is one socket client with
all four subscriptions (15 snapshots, about 1.8 MB, 472,061 bytes measured
because fan-out shares artifacts), not seven stuck subscribers. The lifecycle
amendment gains deploy-time validation, the flyedge cpuset and the absolute
bus dir; a known-limits list records what review round 1 left as notes: feed
counters off the container, store quota per router, rollback while in bus
mode, and the old fixtures.
The two pending decisions, taken for the feed with EDGE-01 and dated:
sizing from the measured 122,367-byte snapshot (the frame is 92,160 bytes,
not the 1.2 MB the list assumed) with the worst case of seven stuck latest
subscribers at about 3 MB inside a 32 MiB tmpfs store; and the lifecycle,
flysim owning the router under /run/fly/bus and starting first, the edge
After= and Requires= it and reconnecting by itself across a crash. Plus the
design as built, the tour's pointer, the example config and the flybus
README's no-longer-true line.
B1: a slot save due at a boundary completes before any State.Capture or FLYSIM01 export there;
the ported milestone archive holds the post-capture ratchet and slot where legacy holds the
pre-capture ones, declared in legacy-gameboy-v1 sections 4 and 16 and step-v1 sections 3 and 6.
N1 the exact restore transient (blocked window from 0 ms, restored winner reported blocked on the
first decode); N2 the decoder-config form; N3 worker status and lost-reply resolution for the
extension methods; N4 boundary actions and captures in the step-v1 section 8 trace; N5 a warm-up
override is another profile; N6 sugar refused until the first commit after a restore.
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).
The survey whole, both arms of the trap hunt, the ROM run, and the residuals --
including the two this row does not work: neither arm reaches rung 11 from this
checkpoint, and the watchdog's check 10 cannot see a loop of exactly four
distinct macros.
Three conflicts, all of them two reviews appending in the same place, all
resolved by keeping both sides: `macros.md` (row 50 keeps section 12.18, row 55
becomes 12.19), `macros-traps.md` (both trap rows, both residual pairs, both arm
sections) and `scene_probe.rs` (both survey modes, `accept` and `shop`). Every
source file auto-merged.
The two rows compose on the cartridge: from the mart checkpoint the fly leaves
the counter, walks the town, and no `MOVE n` blocks any more, so the longest
chain of one macro blocked on an unchanged frame is 1 in any scene.
`macros.md` section 12.18 is the review; `macros-wram.md` section 7.1 corrects
the address table, where `wListMenuID` was said to be cleared by every text
display and an item's position in the stock was said to be its cursor index;
`macros-traps.md` carries row 55, its two arms and its ROM run, and two new
residuals -- `wListScrollOffset` is not a pinned address, and a mart that has
never drawn a buy list reads `Unknown` rather than `Shop`.
take_events kept returning Option<EventBatchView> and defaulting through the
question-mark operator, so a batch missing a field read as end of stream and the
ConsumerEvents enum added in the previous round described nothing. It returns
Batch or Unreadable now, and a test publishes a batch with no droppedBefore,
asserts it is reported as unreadable naming the field, and asserts the next real
batch still reads.
The checkpoint-envelope-v1 amendment cites the rule that lets a required
manifest field land with envelopeVersion still 1 while no production file
exists.
The index an agent attested to at Agent.Initialize joins its compatibility
identity and its checkpoint manifest row, so a replacement fly that built
another graph -- the same dataset, the same neuron count, another index --
cannot install a checkpoint taken under the first one. It was accepted before,
because agent_compatibility digested a dataset digest recomputed from a free
function rather than what the worker attested to, and the restored composition
was then published under its predecessor's indexDigest.
The refusal names what the worker is, not just that two digests differ. Dated
amendment to checkpoint-envelope-v1's agents row; no wire type and no schema
text change, so the contract digest is unchanged.
A group restore re-establishes a committed boundary this epoch did not run a
transition into, so its snapshot carries no decision and no controls for any
agent, and a fresh epoch is a new compositionDigest, so the descriptor takes the
next revision rather than republishing revision 1 with different contents.
CommittedSnapshot's rule becomes: null at boundary 0 and at an installed
boundary, always together, and for every agent or none -- a snapshot where one
fly acted and another did not would be two boundaries in one value. Dated
amendment to publishing-v1 section 3, with the schema set, the fixtures and the
TypeScript package moved together and the digest regenerated.
An undeclared stimulus kind is refused before the model is touched, proved by an
injection through Agent.Commit rather than by a unit call, so the declaration a
descriptor publishes is the thing the worker enforces.
The publishing-v1 section 2 amendment now says in its own words that
Session.GetDescriptor and Session.GetSnapshot are internal and provisional names,
which the later public v2 step may rename or supersede.
Review follow-up on the checkpoint store.
A dropped reply channel and an expired caller budget were both reported as
ReplyLost. They are different facts -- the first means the write is over and its
outcome did not reach here, the second means the save is still going -- so they are
now separate outcomes, and the durable wait has its own budget rather than borrowing
the one that bounds a call to a participant. Both still leave durable metadata where
it was, and for both the resolution asks the store about the same checkpoint.
The writer's two bounds refuse at different moments and the comment claimed
otherwise: the outstanding-capture bound is taken before a capture is requested, and
the byte budget cannot be, because a capture's size is not known until it exists. The
byte check, the decision and the change to the byte total are now one critical
section, the peak is sampled after a superseded job's bytes are gone, and the writer's
own bookkeeping is over a type that holds only the outcomes a writer can produce.
The manifest's coordinator.eventWatermarks is {lastSourceStep, issued}; the fixture
illustrated {lastEventId, lastOrdinal}, and the illustration is what changed, because
an event id is derived from the epoch and cannot be compared across the restore that
gives the session a new one.
checkpoint-envelope-v1 section 3 also now says, under the same dated amendment, that
a required-manifest-field change must bump envelopeVersion once production files
exist: contractDigest is taken over the schema set and does not cover this manifest,
so the envelope version is the only thing that can carry such a change.
macros.md gains 12.18 and macros-wram.md a section 10 for the accessor and the
survey that found it: press at every battle frame with a rollback pulse, and
ask every byte of WRAM and HRAM which of them separates a honoured press from
a refused one.
The half of row 50 that was wrong is where the fix is. The move list was not
drawn: MoveSelectionMenu's cursor bytes are never cleared and SelectMenuItem
decrements wCurrentMenuItem back into the one-based range on its way out, so a
turn's whole text and animation read as an open list with a placeable cursor.
The battle bag is the same trap on wListMenuID and is named rather than fixed,
because the figure that tells its list from the frame after it closes has not
been surveyed yet.
bus-conformance.md still listed the example_demo root count and
session_over_one_router as not fixed here. Both are fixed on main now, so
the rows say what each test does instead: the example waits for the
producer's hold release before reading the counts, with its printed
output unchanged, and the integration renderer is held until the
publisher's twentieth receipt has returned, so its coalescing is forced
and the assertions are order, freshness, acceptance under a stalled
spectator and the replacement accounting, with the before and after
counts.
The delivery check in that test compared (step, sequence) against
(step, step), whose first element can never fail. It compares sequence
against step.
STATE-01 over the FLYSESS1 envelope CONTRACT-01 specified.
fly-session gains a `state` module: the durable store with its generations, its
rotation and the commit order of checkpoint-envelope-v1 section 5, where the store
manifest rename is the durable commit point; a compatibility block whose comparison
names the identity that differs rather than one opaque digest; and a bounded writer
that owns its payload handles until the bytes are committed or the job fails.
The writer's queue slot is taken before the first State.Capture, so a saturated
writer refuses a capture rather than queueing it without bound, and the refusal is a
BUSY the stepping session survives. Capture and durability are two events: a capture
completes when an immutable capture exists, and only the store manifest rename moves
the durable mark. A lost save reply is an outcome, and the resolution asks the store
about the same checkpoint instead of saving again.
Both worker roles implement State.Capture, State.StageRestore and
State.ActivateRestore, with once-only restore tokens bound to checkpoint, scope,
payload and incarnation. A restore selects a complete compatible generation, imports
every payload as a fresh artifact, stages the group, validates the coordinator's own
ledgers, and only then activates; a failure anywhere leaves the fence closed and
records every participant that staged as one that must be replaced. The fence lifts
at Failed -> Restoring(k) -> Paused(k) and nowhere else.
The task and the action executor gain the capture/validate_restore/install_restore
interfaces workers-v1 section 4 lists, and the ledger can re-derive the event
identities it issued under another epoch, which is what lets a resumed run's
behaviour trace be compared with an uninterrupted one.
media: check_required_audio now takes the observation's provenance instead of
exempting boundary 0. A chunk is the audio of an interval, and the observation
ActivateRestore installs covers none.
checkpoint-envelope-v1 section 3 gains a dated amendment adding `environment` to the
manifest, the holder of the world's own payload, which the table named for every
other participant; `helperState`, which that table already listed, joins the
required-field set in Rust and TypeScript. The fixture was regenerated by the
existing example; the schema set and contractDigest are unchanged.
state-media-v1 section 5 gains a dated amendment for three readings this slice
enforces: the State RPCs' compatibilityDigest is the participant's, not the
manifest's composition-level block; a restored observation carries no audio chunk;
and a participant that staged into an abandoned install must be replaced.
publishing-v1 over the same bus: a declared delivery policy per topic, named
publication outcomes, the bounded event batch, application-owned state and cues,
a read-only descriptor query service and a fake multi-agent consumer.
The session publishes the contract types rather than an ad-hoc payload, so a
descriptor says what the workers attested to and a snapshot is checked against it
before it is published and again when it is read: every frame comes from the
boundary its declared delay implies, every handle is the artifact its reference
names, and an observer's refusal takes no world step and fences no epoch.
AgentInitializeResult gains graph (datasetDigest, indexDigest, neuronCount,
rateRoles, supportedStimuli), without which no AgentDescriptor field in
publishing-v1 section 3 had a source. Dated amendments to workers-v1 section 2,
publishing-v1 section 2 and state-media-v1 section 3.
The operator's decision of 2026-09-22: pay the fly for keeping a wild Pokemon,
bump the adapter properly, and restart the live run from an early checkpoint
rather than from scratch.
The rule. `catch` is the catalog's ninth kind, appended so the key order
`counts` serializes in does not move. 0.30 for a species this run had never
owned, 0.10 for a repeat, three payouts per species for the lifetime of the
ledger; the `species` rule is untouched, so a first catch of a new species pays
0.80 across two kinds. The catch is read from `wCapturedMonSpecies` ($d11c),
whose comment in ram/wram.asm is "0 if no mon was captured": ItemUseBall zeroes
it before every throw and writes wEnemyMonSpecies into it only on the branch
that keeps the Pokemon, and UseBagItem's `.returnAfterCapturingMon` zeroes it
again and sets wBattleResult to 2 -- a value written on exactly two paths in
the game, that one and a link battle whose opponent ran. Both are required, so
a byte read out of a half-initialised battle cannot pay. Not wPartyCount: a
catch with a full party raises wBoxCount instead, and wPartyCount also rises
for a gift, a trade and a PC withdrawal.
"Never owned this run" is the `species` payout inside the same battle, because
nothing else can set a Pokedex bit during one. It is not read off the captured
species byte: that is the cartridge's internal index while the owned bitset is
by Pokedex number, and nothing in WRAM converts between them.
The address was resolved by tools/resolve_wram.py, not written by hand. The
tool needed NUM_TMS and NUM_HMS, which the decomp defines through its `const`
enumeration, so it now counts them from the file's own add_tm/add_hm
definitions and cross-checks NUM_TMS against the literal the same file
declares.
The feed's kinds are closed, so `catch` publishes on `wildwin` and nothing in
packages/feed or apps/stage changed. Deliberately not `pokedex`: the `species`
rule already pays for the bit the same catch sets. The stage's ticker copy is
keyed on the feed kind, so a catch row reads "wild win" -- stated in
docs/rewards-learning.md rather than left to be discovered.
v5 -> v6. STATE_VERSION stays 4: the rule adds one counter, `catchCounts`, and
changes nothing else, so a v5 state restores with it empty. That migration is
opt-in and needs all three of: the adapter segment being the only difference
between the two compatibility strings, the running adapter listing the
checkpoint's adapter in `migrates_from()`, and the deploy naming it in
FLY_ACCEPT_ADAPTERS. flysim applies the rule at restore and 05-deploy's gate
applies the same rule before it flips the symlink, writing the variable into
fly.env so the two cannot disagree.
The restart. infra/bin/fly-reset-to-milestone <N> archives both stores to a
dated directory, rewrites milestone-<N>.checkpoint with the ratchet's attempts
and recoveries at zero, installs it as the newest generation of both stores,
clears the milestone archives above N and the event log, and prints what it
did. It refuses while flysim is running and refuses a rung the run never
reached. The envelope work is in flysim::reset (`flysim
--reset-to-milestone N`); the shell script is the operator's wrapper.
Tests: catalog values and order; a synthetic WRAM trace of a catch (new,
repeat, cap, already-owned species, trainer/Safari/old-man/missed-ball
negatives, rollback replay); a v5 state restoring with the counter at zero; a
v5 checkpoint fixture accepted with the opt-in and refused without it; the
reset tool against copies of a state dir in temp directories; and a ROM-gated
catch from a rung-9 forest checkpoint, driven by the shipping THROW BALL macro.
The compatibility string differs from main's in exactly one segment, checked by
splitting both on `/`: pokered-unique8-v5 -> pokered-unique8-v6.
macros.md gains section 12.17; macros-wram.md section 9 gains the frame-by-frame trace of a step,
the three readings that come out of it and the one byte that tracks a step exactly and is recorded
unused; macros-traps.md closes rows 54 and 54b, strikes the two residuals they worked, and prints
both checkpoints' before and after whole -- including the arm where the ethos check's "fewer
flagged windows, more distinct tiles" does not hold, and why.
session_over_one_router asserted that a latest subscriber must drop
snapshots. bus-v1 section 7 says a latest subscription replaces an
undelivered value; it lets a consumer miss values, it does not oblige it
to. Under contention the publisher was slow enough that the renderer kept
up, saw all twenty snapshots and the test failed on conforming behaviour:
16 of 40 runs beside four busy loops, and 9 of 20 whole-crate runs.
The renderer is now held until the publisher's completion is observed
rather than until a timer expires, so the coalescing is forced instead of
raced for: the subscription keeps the one delivery in flight and one
replaceable queued value, and the renderer receives snapshots 1 and 20 of
20. The assertions are the guarantees that hold -- what arrives is in
publication order, the last value is the latest published, the stalled
spectator never refuses a publication or drops out of the fan-out, and
every snapshot the renderer missed is counted as a replacement to the
publisher at admission and to the renderer on delivery, so nothing is
lost silently.
Three more tests in the crate asserted the same kind of race:
- latest_replay_is_ordered_ahead_of_a_racing_publish demanded the
non-coalesced outcome of a race section 7 allows either way ("bounded
mode preserves that order, while latest mode may coalesce it"). It now
puts one racing publication to a bounded and a latest subscription at
once: bounded must deliver the replay and then the publication, and the
latest branch is chosen by that publication's own replaced count.
- collection_waits_for_every_retained_owner, and the two disconnect
cleanup tests beside it, read the store directory for the unlink that
follows the registry update outside the router lock. They use
settle_files, like every other unlink check in the suite.
- The demo example printed a root count taken before the producer's own
release had reached the router, so the line the guide quotes was a
race. It waits for the release, the same way it already waits for
collection; the printed output is unchanged.
Nothing under flybus/src is touched: no routing defect was found. The
conformance rows for the credit/queue split, the replaced count, the
replay ordering and the latest spectator that cannot refuse a publication
now cite what each rewritten test actually varies.
Dated 2026-09-22: where the file lives, what is dropped on load, what an
unreadable one does, that it is not in the checkpoint envelope or the
compatibility string, that FLY_RESET_STATE=1 clears it, and that the bridge
resends nothing on reconnect.
Keep-both everywhere the two slices met. lib.rs takes both module sets.
AgentConfig keeps worker_threads and the sensor log; EnvironmentConfig
keeps worker_threads, the render delay and the render counter.
coordinator.rs keeps the two-stage resolution and its blame() beside the
media split of the Advance reply's attachments, and its imports take both.
harness.rs is main's launcher-based file with this slice's media
instrumentation re-applied on top.
The media instrumentation is shared memory, so it now follows the
launcher's own rule for the progress counter: sensor_log and renders
return None for a participant with a process of its own rather than a
misleading zero. The launcher carries the sensor log and the render
counter to a participant in this process and the render delay and the four
media faults on the command line to one in another process, where the
child builds its own log and counter.
The media path itself is mode-agnostic and is now tested as such: one
image per boundary, forwarded to every agent and published once, asserted
over the bus in all three execution modes, with the shared-memory
assertions made only where those participants live.
Review fixes for SESSION-02.
An expired caller deadline was becoming a failed epoch without the
ipc-v1 section 6 resolution. That procedure existed and was correct and
had exactly one caller, a test injection, so the deadline this slice
introduced bypassed it and a merely slow participant lost its epoch.
Deadlines is now the two-stage shape section 6 describes -- a probe,
then a bounded resolve budget and attempt count -- call_owned returns a
typed CallOutcome so an expiry is distinguishable from a refusal, and
Prepare, Commit, Advance and the lifecycle calls all query the same
request id against the same incarnation before the epoch can fail. This
is also step-v1 section 7's Advance row, which was imperative about it.
The coordinator peak-RSS column was measuring the measuring process.
VmHWM never falls and every row shared one process, so the column was
cumulative and the mode ranking reversed when the rows were reordered.
Each row now runs in a measure-row child of its own. The corrected
numbers say the opposite of what the first report claimed: the
coordinator's own peak is roughly flat across the modes and lowest in
process mode, and the cost of the split is the children.
workers-v1 section 2 bounded Agent.Initialize's workerThreads by
"within launcher allocation" and named no wire for it. Dated amendment:
HelloResult.limits gains workerThreads, the worker reports what its
launcher gave it, and the launcher refuses one that disagrees. The
schema set, the shared fixtures and the TypeScript package move
together; contractDigest changes, which ipc-v1 section 4 provides for.
Also: the stale-epoch row now reaches the stale-epoch path against a
live agent process and asserts exact codes on both halves; the
router-restart row asserts the handle drop it claimed; frames are
counted from the behaviour trace instead of calculated; the README says
which suites run over which transports; bootstrap is fence-guarded; the
shutdown reason is an Id rather than a silent fallback; and
agent_mutations returns None rather than zero where the counter lives
in another process.
