079842f818 media: no best-effort defaults in the audio path
Review round two.

A restored timeline refuses a declared stream with no recorded sample
position instead of resuming it at zero, which would have restarted the
episode's audio clock silently.

A declared stream that produces no chunk for a transition now fails the
step. The contract does not say a chunk must exist; this slice requires
one, because a silently missing chunk cannot be told from a lost one.
Boundary 0 is exempt: no interval precedes it.

The fresh-epoch discontinuity refusal is dropped rather than written into
the amendment. Only the restore direction is stated, and sections 6 and 7
both have a fresh timeline publishing a discontinuity after a recovery or
a reset, so refusing the flag at an origin contradicted them. The dated
amendment now says the requirement is one-directional.

A snapshot with an unreadable chunk, or one whose handle is not attached,
is now unreadable as a whole rather than quietly carrying less audio than
was published. ViewPipeline::is_bootstrap_repeat is removed.

New tests: a missing chunk fails the step, restored timelines need every
declared stream's position, and a 7 Hz world's seven chunks sum to exactly
one second of 48 kHz samples. The bus-conformance reconnect row also cites
the test that actually replaces an incarnation.

8ef5dc321d macros: the Pewter run bounds the walks that complete without moving
Section 12.2's rule as a number on the cartridge: the longest chain of `GO ...` macros that
completed at a net of zero tiles. One is ordinary -- a walk that arrives by turning, a walk cut
short by a battle, a walk that finds its goal underfoot -- and a chain of them is the loop the
v0.4.5 after arm spent brain minutes 1.0 to 8.5 in. Three is the bound.

611fe9e108 macros: an errand arrives inside the building, and a building already entered has none
Two rules for section 13's errands, both from row 54's `GO HEAL`: 204 starts at a mean net of 0.0
tiles and a mean reach of 0.0, cycling with `GO ROUTE` and `GO FRONTIER` over five tiles for seven
and a half brain minutes.

An errand's aim at a door carries no press -- the warp fires when it is stepped on -- so an aim on
the tile the fly is already standing on settles for `SETTLE_FRAMES` and reports `done` with the
world exactly as it was. A completed errand walk writes the reached ledger, which `goals_toward`
does not filter, so the same button was dealt on the next hold and the same nothing happened again.
`exit_goals` has excluded a settled goal underfoot since row 13; this is the one walk that did not
have the rule.

And the errand ledger is session state, so a restore re-armed every errand in the town and walked
the fly back to a counter it had already used. `map_visited` is the adapter's lifetime answer to
the same question and it does survive, so both are asked and either pays the errand.

895fb52cda macros: the tile a step is landing on is ground the run has covered
The other half of the same measurement. `wXCoord` and `wYCoord` are the tile the step began on
until the frame it ends, so the stood ledger recorded ground the fly had already left and the tile
under it stayed unstood: `path::frontier` kept offering it, `GO FRONTIER` was dealt aiming one tile
away, and `Arrival::Step` reported `done` the instant the step it did not make landed. A macro that
completes without changing anything, which is section 12.2's trap.

A step that has begun always finishes -- the cartridge owns the animation and no press stops it --
and the screen has already centred on the tile, so it is ground this run has covered. It clears the
map's frontier mark on the same rule the coordinates do: only ground never stood on before.

31f35c6f2f macros: the whole-map grid is read from the tile the screen is centred on
Measured on the cartridge from the rung-10 checkpoint: `wXCoord` and `wYCoord` change at the *end*
of a sixteen-frame step while the background scrolls throughout it, so for fifteen frames of every
sixteen the screen buffer is centred one tile ahead of the coordinates. The cross-check compared
the decode of the fly's own tile with the screen's reading of the tile ahead and refused. Pewter
City decoded on 118 of 120 standing frames and on none of the moving ones, so every walk the fly
actually took was re-planned over the ten-by-nine window, which is the oscillation of row 23.

Nothing in the pinned symbol table says "a step is in progress" and a new address cannot be pinned
without the disassembly `gen_symbols.py` reads, so the anchor is measured rather than named: the
screen is centred on the fly's tile or on one of its four neighbours, and the one it is centred on
is the one whose whole neighbourhood agrees with the decode. A decode with a wrong stride, a wrong
quadrant or a half-loaded map agrees with none of the five, and neither does the mid-warp tear the
per-serve check was added for, so both refusals stand.

`state::step_destination` names the tile the step is landing on, for the ledger the next commit
writes. The town fixture gains two landmarks beside the fly, because a neighbourhood that is the
same tile id in every direction cannot tell one anchor from another.

ed1d321b02 probes: a mid-step survey, and the errands on the pad dump
`FLY_PROBE_CATCH=step` holds one direction from a checkpoint and prints, per frame, the
coordinates, the grid's verdict, the tiles the cross-check disagreed on and every candidate for
"a step is in progress". It is what row 54 turns on: whether the coordinates change at the start
of a step or at its end.

The pad dump gains section 13's two errands -- which building each names, whether the ledgers have
paid it, and what the walk would aim at -- because an aim with no press settles where it stands.

903629db00 docs: what MEDIA-01 enforces in state-media-v1 section 2
Two readings of the section that are now checked rather than assumed: the
bootstrap window is exactly the boundaries where max(0, boundary - delay)
is zero and its repeated O[0] is the same artifact, and a chunk that
continues the previous one exactly cannot claim a discontinuity, which is
what keeps the restore rule checkable instead of advisory.

7b7ebcdf28 session: parallel processes, a launcher and the fault behaviour
SESSION-02: one agent process per fly and one environment process under
the coordinator over the Unix-socket transport, compared against the
in-process composition and a dedicated-thread variant. The mode is the
only thing that changes; the composition, the coordinator, the workers
and the router are the same code in all three.

The launcher is the configured supervisor. It owns a total thread budget
with one allocation per participant, refused as BUSY before anything
starts when the total cannot cover it; the configured client, service,
worker and port identities, proved in Worker.Hello before the
coordinator pins a registration; Worker.Status health on the
supervisor's own monotonic clock at the ipc-v1 section 6 budgets; and
reaping, where Worker.Shutdown is the request and the operating system
is the guarantee.

The worker executable is a subcommand of this crate's one binary, which
is what implementation.md section 2 allows in place of a separate
worker crate.

The coordinator's fault behaviour: every failure names the participant
it is attributed to, every domain call has a caller-side deadline so a
dead participant is a diagnosed outcome rather than a hang, and failing
fences the epoch -- the boundary stops, the handles drop, and no further
transition or publication is allowed. Agent.Initialize now carries the
launcher's allocation, and an agent refuses one asking for more.

tests/processes.rs proves every acceptance bullet once per execution
mode, and the two section 4 rows SESSION-01 could not reach in one
process: a router restart during a world advance, and an old worker's
reply after a restart. measure compares the three modes at one, two and
four agents; its table is in the crate README, and it is not a capacity
claim.

8afeaf6c92 bus: wait for the teardown the disconnect test asserts
caller_disconnect_cleanup_works_before_and_after_consumption failed 37 times
in 240 runs under load: the reply raced the router's own teardown. op_reply
reports routed:false only once disconnect has marked the call detached, and
the router runs that when its connection task reads EOF, while Client::close
waits for this client's reader only. The reply could therefore reach a
connection that was still closing and be routed. Nothing escaped -- teardown
releases those roots -- but the flag was read one step early.

The test now settles on the caller's connection being gone before asserting
the section 6 sentence, which is the poll the rest of the file already uses.
360 runs after the fix, 0 failures.

bus-conformance.md records the mechanism, the counts and the two other
intermittent failures seen in the same sweep, which are left to the bus slice.

40c6a88949 media: native observation schemas and the presentation handoff
Puts MEDIA-01 on top of the bus ArtifactRef rather than beside it.

fly-session-types gains the two validators a descriptor and a reference
cannot carry on their own: AudioTimeline, which holds one stream chunk
sequence for one epoch (no overlap, no backwards, the first chunk after a
restore marks the discontinuity), and check_imported_asset, which checks
that a transient artifact carries an installed asset content without ever
converting one identity into the other.

fly-session gains a media module: a ViewPipeline that renders one native
frame per boundary and serves the frame the declared observationDelaySteps
requires (so bootstrap repeats O[0] exactly while the pipeline fills), an
AudioSource with an exact rational sample budget and a deterministic
integer-phase waveform, the Phase C acceptance checks, a latest-subscription
Spectator with finite credits, a SensorLog recording what each agent read,
and an AssetRegistry for installed persistent content.

The counter arena now emits a real 32x24 RGBA8 pattern per boundary and one
audio chunk per transition; the coordinator forwards the one owned view
handle to every agent Commit and publishes the same handle, with the audio
handles, for presentation.

36 new tests: 12 shape rules against the contract crate and 24 session-level
acceptance tests over both transports.

57de8126d5 fix(session-types): check the rational addition, and hold the schema set to the readers list
Two fixes from the independent review of f043cd7.

RationalNs::checked_add cross-multiplied into u128 and then added without a check. Each
product fits, but their sum does not: two reduced fractions near the U64 maximum add to about
2^129, which panics in debug and wraps in release, after which the reduction returns a
confidently wrong rational. Every multiplication and the addition now go through a checked
path, as ipc-v1 section 2 requires, with a fixture row and a test that reaches the overflow
rather than the "does not fit U64" reduction limit.

The schema-set test checked fourteen hardcoded type names, so a new payload type could have
shipped outside contractDigest. It now iterates the readers own list, all fifty of them.

Also amends ipc-v1 section 5, dated: Worker.Acknowledge carries req-<U64> request ids, not
arbitrary Ids, because the serial watermark rule in that same section cannot reject reuse
after acknowledgment unless the acknowledged id carries its serial.

4edc4c9bcf tests: ROM-gated, the fly gets out of the museum and into the gym
From the live rung-10 checkpoint with the stub rotation: map 0x34 to map 0x36 on frame 2423, on
15 macros, against never in five and a half live hours. TALK is on the pad inside the gym -- the
fly standing in front of one of the people rung 11's place names -- and it presses it 15 times
there. BACK on a dialog or unknown frame is 0 against the 189 the hunt measured on Pewter City
alone, no frame deals a pad on an unknown with nothing drawn on it, and GO FRONTIER starts 0
times on the museum's two floors.

The unit test beside it is the other half of "the objective reaches the leader": on the gym's
own map the rung's place resolves to the person standing in it, the walk aims at the four tiles
around them, the door is not a candidate while they are there, and talking to them empties the
list. It also pins what the ROM run showed: the town's errands come first for every map in the
area, the gym included, so both have to be paid before the objective is the leader.

0d098ee408 session: both transports for every integration test, and the mid-step pause written into step-v1
Review found two Memory-only tests behind a README claim that every integration test runs
twice. Both are now generated by both_transports!: the one-agent composition, and the
old-epoch refusal, which is one of the three tests the old-worker-replies row cites. The
README says which single test walks both transports inside itself instead, because it
compares their traces against each other.

step-v1 section 2 gains the mid-step pause line and a dated amendment saying why it is not
a new edge: a pause requested during a transition is the ordinary
Committing(k) -> Ready(k+1) edge followed by Ready(k+1) -> Paused(k+1), because section 6
requires the transition to finish first, so the only boundary such a pause can land on is
the one the transition just committed.

e0285016aa ratchet: getting nearer the objective is progress the coverage figure cannot carry
Two Stuck rollbacks fired on rung 10 inside half an hour, both on a fly that was walking, and
both were the ratchet working to contract: the stall window is reset by exploration -- one tile
the run has never stood on -- and a fly crossing a town it has already covered to reach the
rung's own door earns none of it. Entering a map for the first time already counts, because a
new map is ground nobody has stood on; re-entering one does not, which is what the museum was.

So the window gains a second signal, passed in by the caller and meaningless to the ratchet
itself, exactly as coverage is: the Pokemon loop answers with "nearer the objective, in map
hops, than this run has ever been", over the same map graph GO OBJECTIVE walks. It can fire at
most once per step of the road, it spends no budget, it captures nothing and it skips no
trigger. Nothing in the macro layer reads it back and no button is bound on it.

The checkpointed ratchet state is untouched: the signal is a level on one sample, not a counter.

26f957e084 macros: a frontier no walk can reach is a fact about the map, not a window
GO FRONTIER was 1,235 of the rung-10 run's macro starts in 47 minutes, over two museum floors
and a town whose ground the fly had already covered. The tiles it aimed at were real and
unreachable: 98 walkable tiles on the museum's ground floor, 62 of them reachable from the door,
39 never stood on and almost all of those behind the admission desk. A walk that can reach none
of its goals refuses no route and writes every goal to the blocked ledger -- which is a ten
brain minute window, so all of it came back and the refusal happened again, once per hold.

A window is right for a target somebody is standing in front of and wrong for ground the map has
fenced off. So the refusal is remembered per map instead, with no window, and it is cleared by
the one event that can change the answer: the fly standing somewhere on that map it had not
stood on before -- a door opened, a script carried it through, somebody moved out of a doorway.
Re-entering the map clears nothing, which is the loop the window made.

84ed0410bf macros: an UNKNOWN frame with nothing drawn on it deals no buttons
BACK was 678 macro starts in 47 minutes on rung 10, 189 of them on Pewter City with no text box
on screen at all. BACK is on no overworld and no dialog pad, so every one of them was dealt by
Scene::Unknown -- which holds two states under one name. One is a screen this crate cannot name,
the Pokedex or the trainer card or OPTION, where A and B are what leave it. The other is a frame
of the overworld where the cartridge is driving -- a warp in flight, a scripted push-back, the
museum guide walking the fly through the door -- which the detector calls Unknown because the
buttons are not reaching the player.

On the second, NEXT and BACK are an A and a B pressed into somebody else's script: they change
nothing and they complete where the fly stands, which is section 12.2's trap with no box to
advance. So Unknown's pad is dealt on whether a box is drawn, and a scripted overworld frame is
an empty pad the fly waits out -- the cartridge gives the buttons back by itself.

a389734201 geography: the Pewter museum is two rows on the map graph
Rung 10 spent five and a half hours in Pewter City with the objective two doors away, and the
fly kept ending up inside the museum, where GO OBJECTIVE, GO SHOP and GO HEAL were all off the
pad: a map with no row in the graph has no neighbours, so next_hop answers nothing and area_of
answers nothing. Named as a residual by the previous review and worked here.

Both ids come from the cartridge's own warp table, surveyed from the rung-10 checkpoint rather
than counted: Pewter City names 0x34 at (14, 7) and at (19, 5), which are the museum's two
doors, and 0x34 names 0x35 at (7, 7), which is the staircase. The upper floor has no area, for
the same reason a bedroom has none -- no front door of its own -- and the road out of it is the
staircase, which is what the fly needs there.

99a6a08bad probes: say which tile the map decode and the screen disagree about
The rung-10 review needed to tell "the whole-map grid is wrong on this map" from "this frame
was mid-step", and the refusal label cannot: both read "screen disagrees". So the decode is
split from its own cross-check, the disagreement is readable tile by tile, and the map survey
stands still for a while and counts how many of those frames decode.

On Pewter City, measured from the rung-10 checkpoint: standing still it decodes on 118 of 120
frames, and the frame the survey caught disagrees on three tiles by exactly one tile row in the
direction the fly was walking. The map is fine; the reading is refused while the fly is moving.

c3bda90b82 test(flybus): prove the two section 9 rows a review found cited but unproven
An independent review of 4f44894 accepted the audit with two required evidence
changes, neither of which needed a code change.

"Classification is not a topic-name heuristic" cited a lane-order test that
never varies a topic name. The row is now conforms-by-construction, naming the
four scheduler functions that read only the queue an item sits in, and
a_topic_named_like_a_notice_is_still_classified_as_topic_data publishes on
topics called call.failed, route.removed and subscription.closed and asserts
each arrives as a topic.message delivery with its payload intact.

"A latest subscriber never causes BACKPRESSURE" cited a bounded-mode test and
the ignored measurement. a_latest_subscriber_never_refuses_a_publication floods
one unconsumed latest slot with 100 publications of 60 KB, six times the
per-client bounded byte pool, and asserts none is refused, 98 coalesce, the
queue stays at one and the credit never comes back. That row also underwrites
the byte-budget deviation and the first contradiction.

Both tests run over both transports.

The coordinator resolved both contradictions in the spec rather than the code,
so bus-v1 carries them as dated amendments with one line of reason each: the
section 9 table row becomes "Per-client ordinary bounded queued envelope bytes"
with a new "Latest subscription slots | subscriptions x 64 KiB" row, and the
section 2 sketch drops the budget argument and shows the deadline at the caller.
With the amended wording the byte-budget row conforms, so the report's counts
are 178 / 9 / 1 fixed / 7, and the crate README's differences 4 and 8 say they
no longer differ.

52ad46ecb0 refactor(session): build the session slice on the shared fly-session-types crate
CONTRACT-01 landed its crate, so the local stand-in module goes away and the domain
scalars, method payloads, their validation, the canonical digests and the trace format
all come from the contract. `src/types.rs` is a facade over that crate plus the few
things a coordinator needs that are not part of the type contract: a session-side
DomainError, the synthetic composition's schema and event-id derivations, and the
coordinator-local ControllerIntent, PortBinding and AgentOutcome that never cross the
bus.

Consequences worth naming:

- Payloads are read and written through DomainType::from_json / to_json instead of
  serde derives, so a misspelled required field fails where the contract says it
  should. serde, sha2 and ryu-js leave this crate's dependencies with them.
- The step-v1 section 8 trace is the contract's TransitionTrace, with behaviour and
  operational metadata already separated; the dispatch-order comparison now runs over
  the contract's own behaviour encoding.
- Two things the migration found. IN_PROGRESS is raised strictly before any mutation,
  so its certainty is "none", not "unknown"; the local module had it wrong.
  WorldObservation::validate_against checks the views a result carries but does not
  require every declared view to be present, so requiring them is made explicit in the
  coordinator's phase C check, where step-v1 puts it.
- The lost-Advance-result injection now waits for the worker to report the operation
  before abandoning the call, so the case it injects really is a loss after dispatch
  rather than a cancellation before it.

Gates: cargo test -p fly-session (61 tests, both transports), cargo clippy
--all-targets clean, and the runnable example produces the same behaviour trace over
both transports.

4f44894ede docs(design): a bus-v1 conformance report, and the amendments it asks for
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.

cf757af510 test(flybus): assert the example's output, and split the frame measurement up
The guide's first deliverable is one small program with a counter RPC, a pub/sub
observer and a frame artifact held past its message object. examples/demo.rs was
already that; its body moves into run(), which returns the lines it prints, so
tests/example_demo.rs can assert all seven of them. The counter now uses the
spec's own example.counter / Counter.Increment / {"amount": 1} and pins the
registration it discovered, and the example prints the router's root count while
the frame is held and after the last handle goes, so the lifetime it
demonstrates is visible rather than implied. cargo run -p flybus --example demo
prints the same lines.

tests/perf.rs reports what BUS-03 and bus-v1 section 11.7 actually ask for.
Allocate, the producer's copy into staging, the router's seal copy, publish
admission, the RPC round trip and a consumer's readback are six separate
percentile lines instead of one. The router gets its own two-thread runtime
whose threads carry a distinct name, and per-thread CPU is sampled from /proc by
that name, so router CPU is separable from the clients' in the same process.
Store bytes, outstanding roots and queue lengths are reported live as well as
peak.

One named test per implementation-guide bullet that the existing suites did not
already cover: a lost result that leaks no roots while the endpoint's own cache
still replays it, a retransmission of one domain body under a fresh call id, no
failover onto a replacement registration, a status RPC answered while another
handler is delayed, and a disconnect that reclaims logical ownership without
touching a file the consumer still has open. Each runs over both transports.

BUS-01 also asks for equivalent behaviour traces from the two transports, so
tests/common/mod.rs gains a Trace recorder whose record() panics on any
router-issued id: a trace can hold methods, payload fields, counts, sequences,
credits, cancel states and error codes, and nothing operational. One RPC
scenario and one pub/sub-with-artifacts scenario produce 29 events, identical in
memory and over a Unix socket. FLYBUS_TRACE=1 prints them.

The sixteen bullets the older suites already prove are cited in the conformance
report rather than duplicated here.

7708bf12cd fix(flybus): stop connection teardown being starved by the frame it waits for
The write gate was one mutex the writer held across every synchronous transport
poll, and close_conn took that same mutex before reclaiming a connection's
owners. Under a transport that accepts a byte per poll the writer re-acquired it
hundreds of times while teardown queued behind it, so teardown could be starved
for a whole frame and the delivery completed just before its owner was
reclaimed. bus-v1 section 9 puts release and route-health control out of reach of
telemetry starvation; tests/sol_rereview_regressions.rs's poll-gate regression
failed 6 release runs out of 6 alone, and about one debug run in five.

The gate now separates "teardown has begun" from "a poll is in progress": a
mutex plus a condvar. begin_close sets closing once without waiting, then waits
for the poll already in progress and records whether it left a frame half
written. The writer brackets each poll with enter_poll (refused once closing)
and leave_poll(bytes) instead of holding a lock across it, so teardown's window
is one poll rather than a frame, and no byte follows it. close_conn no longer
holds the gate across reclamation. Every item is pub(crate): no public
signature changed.

The regression test no longer synchronises with a sleep. The shutdown thread
announces itself on a channel, and what follows is structural: teardown cannot
pass the gate until the held poll returns, which only release() allows. Its
delivery is 50 KB now, which a writer resuming a byte per poll cannot finish
inside the window, so the test observes the ordering instead of a coin toss and
asserts the two legal shapes of the stream: cut short with nothing appended, or
never begun with exactly the closing notices following.

c567727351 feat(session-types): the TypeScript half of the contracts, over the same fixtures
packages/session-types mirrors the Rust crate: canonical JSON (RFC 8785), strict parsing,
canonical digests, readers with a validate step for every payload of ipc-v1, workers-v1,
state-media-v1 and publishing-v1, the trace comparator, seed derivation and the FLYSESS1
envelope. It loads the crate fixtures/ directory rather than keeping a copy.

43 tests with node test runner, as in packages/feed. Both languages assert the same recorded
canonical bytes and digests, so agreement is checked rather than assumed; the envelope test
goes further and requires the bytes this package writes to equal the fixture the Rust crate
wrote.

Also narrows the canonical number rule to a value-based one (finite, and within the exact
integer range when integral), because JSON.parse cannot tell 1e21 from the same digits
written out, and two implementations that disagree about one number agree about no digest.

5defb6766d feat(session): fly-session, the SESSION-01 synthetic sequential transaction over flybus
The lockstep coordinator, its phase machine and a synthetic composition, as a new
workspace member. Every worker method is a Flybus RPC to an incarnation-pinned
service; the domain request ids and result caches of ipc-v1 section 5 sit in front of
every mutation.

- coordinator: the step-v1 section 3 transaction in order -- prepare every agent
  concurrently, run one executor per agent in sorted agent-id order, assemble all port
  controls in descriptor order, send exactly one Environment.Advance, evaluate the task
  once, commit every agent concurrently, and move the committed boundary only when all
  of them succeeded. Sequential, concurrent and reversed dispatch are selectable and
  must agree.
- phase: the section 2 machine as an explicit edge table, Paused and Failed included,
  with a committed-boundary predicate that gates pauses, captures and publication.
- clock: checked rational accumulation. A 60 Hz world with a 1 ms model tick runs
  16, 17, 17 ticks and comes back to a remainder of exactly zero.
- dedup: operation keys, the cached reply with its own artifact holds, CONFLICT,
  IN_PROGRESS, RESULT_EXPIRED, STALE_STEP, the lifecycle bound and Worker.Acknowledge.
- worker: the dispatch shell. Admission order and the result cache live here; the
  endpoint mutex is the worker's simulation lock, so one mutation runs at a time while
  Worker.Status answers from a separate cell.
- agent, environment, task: a fake model with an explicit seed and a mutation counter
  the tests read, a fixed readout stub, a counter arena that seals one immutable frame
  per boundary, a deterministic task and the identity executor.
- fly_session_types: the CONTRACT-01 domain types as a local stand-in, reconciled with
  the shared crate in a following commit.

Tests run twice, over the in-memory transport and over a Unix socket, through the same
router: the SESSION-01 acceptance bullets and every section 4 failure-injection row
that applies to this slice.

1652afad11 test(session-types): the CONTRACT-01 fixtures, cross-checks and their Rust tests
fixtures/ is the shared contract corpus: accepted payloads with their canonical JSON and
digest, refused payloads with the rule each breaks, raw byte sequences that must not even
parse, recipes for the payloads too large to store, the U64 and double boundaries, rational
arithmetic vectors, the identity matrix, descriptor cross-checks, operation keys and bodies,
trace comparison variants, the schema set and its digest, seed vectors and one FLYSESS1
envelope. packages/session-types loads the same files.

Tests: 45 across nine files. Round trips preserve every field and reproduce the recorded
canonical bytes; duplicate keys, invalid UTF-8, NaN, trailing data, oversize typed values and
oversize envelopes fail; U64 and double boundaries reject on the right side; the four
identities never accept one another spellings; the accumulator produces 16, 17, 17 and a zero
remainder; the trace comparator ignores wall time, request ids, callIds and delivery ids and
notices every behaviour change; the contract digest survives reformatting and moves when a
field, bound, enum member or type changes.

Also: a crate README, and the update_fixtures example that regenerates the derived files.

d2b916602e feat(session-types): the fly-session-types crate: domain scalars, closed enums, method payloads, canonical JSON and digests
The CONTRACT-01 type definitions, committed early so the session slice can build on
them while the fixtures and cross-language tests are still being written.

- scalar: Scope, RationalNs (reduced, positive denominator, 0/1 zero, checked
  arithmetic and the step-v1 accumulator), SchemaRef, TypedValue with its 32-KiB
  canonical-JSON cap, and the four identities that must not be confused (bus callId,
  domain requestId, artifact identity, delivery/hold owner token) as distinct types.
  Id, U64 and Digest call into flybus::wire instead of forking the encodings.
- canonical: RFC 8785 canonical JSON, SHA-256 digests, the operation key and the
  canonical body rules of ipc-v1 section 5, with bus identities refused in a body.
- rpc, workers, media, publishing: the payloads of ipc-v1, workers-v1, state-media-v1
  and publishing-v1, each with a validate step for the documented ranges, uniqueness,
  ordering and bounds.
- schema: the canonical schema set, whose digest is contractDigest, declared as data
  so source formatting cannot change it.
- trace: the step-v1 section 8 record, behaviour separated from operational metadata.
- seed, checkpoint: the seed derivation and FLYSESS1 envelope layout.

The first run of the new ROM test failed on YES 134, and every one past

the fly playing the game, not the ring. Row 41 is about the presses spent

0bf4b965fb macros: tests for the nurse's box
Unit: HEAL is off a full party's pad, including the rung-10 party's own
numbers, which is the assertion that the loop was never the heal's; TALK
is off a rested nurse's pad and on a hurt one's, and an ordinary
villager is unaffected; her prompt deals one answer and a plain box still
deals three; a readable prompt that is not hers deals both answers and no
NEXT; an answer whose prompt reopens is excluded and one that settled the
box is not; a completed heal and a declined prompt both retire her.

ROM-gated from the live checkpoint (FLY_CENTER_CHECKPOINT): the fly
leaves map 0x3a on a bounded number of macros, YES starts stay under
five, NEXT is on no pad while a prompt is readable, and TALK is on no pad
at a rested nurse. The run also counts dialog and prompt frames, which is
what makes the forty-six-to-one ratio visible.

70a2433e25 macros: the nurse is talked to once, and a reopened box excludes its answer
TALK's precondition reaches over a counter because the cartridge does;
its talked-ledger entry was read one tile ahead. So TALK was bound at the
counter and recorded nothing, 107 times, and the nurse was never retired.
The entry now comes from the same reading the precondition makes.

A completed HEAL writes her into the talked ledger: the macro has had the
conversation with its own presses, and the reached window would otherwise
expire in ten brain minutes and offer the ring again. A declined prompt
writes it too -- 12.4 inverted for one person, because the pad only ever
offers NO at her prompt when the party is already full.

And the general rule: a YES or NO whose prompt is up again on the same
map and tile within one hold did nothing, so that answer joins the
blocked ledger for its window.

ce7644e2e8 macros: a choice's pad is its answers, and TALK is not a nurse's errand
On a box that is a readable YES/NO prompt, NEXT is YES under another
name -- an A press at a two-option menu confirms the option the cursor is
on -- so it is off that pad and the pad is the box's two answers. That is
12.10's pair rule in a dialog.

At the nurse's own prompt only the answer that changes something is
bound: YES with a hurt or statused party, NO with a full one, read from
the same byte HEAL's precondition has read since section 13.

And TALK is off the pad at a nurse the party has no use for. Her
conversation is a service whose need the cartridge publishes, and a ring
of text that ends where it began is section 12.2's trap. Nobody else is
narrowed.

An answer the reopened-prompt ledger excludes leaves the pad, and the
exclusion never empties one: a box nothing can answer cannot be left.

86f0e7018d macros: read the nurse's YES/NO box, and survey her conversation
Row 41 is the Pokemon Center nurse: 2,142 YES starts on one tile of map
0x3a with a party at 70/70. The survey that names it is a new probe mode
(FLY_PROBE_CATCH=nurse) that leaves the box with B and then pulses A,
printing every state the conversation passes through with the two-option
menu's own geometry beside it. It is a ring of forty-six presses and the
box is a choice on exactly one of them.

So the reading: wFontLoaded plus the border DisplayTwoOptionMenu draws,
plus the cursor it parks inside it. Both halves are needed -- the cursor
bytes survive the box closing, so all forty-six frames carry the
geometry. It claims that box and not "a choice is open" in general.

TargetKey gains Answer { at, yes } for the reopened-prompt exclusion.

dedcf3ad8e macros: say what the cursor rule found, not the first reading of it
The doc comment on Cursor::want credited THROW BALL's 63 blocked starts to the
bag drawing slowly, which is true of the frames and not the cause. What the rule
did was make the step report which list it had been left looking at, and the
answer was never the bag - it was the party list, because battle_entry's ITEM and
PKMN were the other way round. The rule stands on its own: a step that reads the
list it has already answered takes its length and its direction from entries it
is not walking.

c06d3206e2 docs: section 12.11, and rows 44 to 47 of the trap audit
The rung-10 loop whole: which building the fly was in, why every candidate list
on that map emptied, the byte dump that named the battle menu's swapped entries,
the ROM-gated before and after, and the two arms of the trap hunt being identical
because a restore clears the ledgers the loop was built out of.

Section 13.1's tables follow: MENU off both overworld rows and off the narrow
counter row, the move list's conditional BACK, the start menu reachable only by
the raw START button, and two new rows in the pad-empty audit - the room whose
one door the ledger rests, and the map with no way out at all, which is the one
empty pad left and is asserted rather than covered.

0163c66f6a tests: ROM-gated runs for the building pad and for the bag and party lists
A new test from the rung-10 Pewter checkpoint: the fly is on map 0x35, the
museum's upper floor, the objective is the gym where the badge is, and over
thirty-three brain minutes MENU is on no overworld pad, no overworld pad is
empty, MENU and BACK never alternate, and the fly leaves the building on frame
182. On v0.4.3 the same test fails at the first of those: MENU is on the pad of
maps 2, 52, 53, 54, 55, 57 and 58 with 147 starts.

The harness records where a macro reported blocked, which is what identified the
battle menu's swapped entries, and the forest test now asserts THROW BALL never
blocks: 15 starts and 0 blocked from the rung-9 checkpoint, against 6 of 6.

Its bound on a battle's macros goes from 400 to 700 against a re-measured worst
of 450, because a fly whose SWITCH and ITEM reach their own lists fights longer
than one that can only attack. Every battle still ends: 3 of 3.

57d9bdff5a macros: Red's battle menu is two columns, so ITEM is under FIGHT and PKMN beside it
THROW BALL was 63 starts and 63 blocked on v0.4.3 and SWITCH 15 of them, and the
reason is neither macro's own script. The screen reads FIGHT PKMN over ITEM RUN
and the game's index does not: wCurrentMenuItem is the row inside the column the
cursor is in, and selection adds two for the right column, so the order is
FIGHT, ITEM, PKMN, RUN. battle_entry had PKMN 1 and ITEM 2 -- the row-major
reading of the picture -- so every macro that meant to open the bag opened the
party list and every macro that meant to open the party list opened the bag.

Surveyed on the cartridge from the rung-9 checkpoint: a THROW BALL aiming at 2
walked the cursor to wTopMenuItemX 15 / wCurrentMenuItem 0, pressed A, and the
party list opened -- wTopMenuItemY 1, wTopMenuItemX 0, wListMenuID $02 -- with
the game writing wCurrentMenuItem 2 on the frame after the press.

The fake had the same mistake in its own geometry, so it could not have caught
it: its two-by-two moved row-major. It is column-major now, like the cartridge.
