Both heads that carry code are 14/14 green — `2d9c678` (the fixes and
the framing) and `668fc72` (this block). The tip row is explicit rather
than missing: a checkpoint table can never record the head that adds
the checkpoint, and #215's lane used the same convention. The branch
tip stays authoritative over any row.

Fills in what could only be filled in after the fact: PR #216, the
opening head's CI run, and the four-way sweep table. Both branch totals
are exactly +4 on their baseline — the four witnesses, and nothing else
moved.
**A shared `CARGO_TARGET_DIR` makes a local sweep unattributable, and it
bit this lane.** The branch `crdt` sweep first reported seven failures
in three suites while the baseline `crdt` sweep was clean. All three
spawn the REAL `pmacs` binary out of the target directory, and the
failure text named its own cause — "daemon does not advertise required
capabilities … start the daemon built with the `crdt` feature". A
concurrent `cargo test --workspace` in a DIFFERENT WORKTREE, at default
(non-`crdt`) features and the same `CARGO_TARGET_DIR`, had overwritten
`target/debug/pmacs` mid-sweep. Confirmed with `pgrep` while it was
happening, and discriminated by re-running the same three suites from
the same tree with a dedicated target directory: 41/41 green, then the
whole configuration swept again there. Recorded in the handoff's
standing hazards, beside the feature-blindness rule it rhymes with: a
feature-flavored binary is a shared mutable file, not an artifact
private to your invocation.
The clean re-sweep left ONE failure, and it is recorded rather than
rerun away: `lsp_dispatch_seams_acceptance acc33_...`. It is a new
incident by the registry's rules, and it is not attributable to this
branch on a STRUCTURAL argument rather than on its green rerun — the
only Rust change lives in `#[cfg(test)] mod tests`, which compiles into
the lib test target alone, so an integration-test binary linking the
non-`cfg(test)` lib is exactly what `main` builds. CI's `Test (crdt)`
job passed at the same head and runs that suite. The 15/15 repetition
set is the weakest of the five points, not the argument. No registry
row is opened: the registry judges red CI runs and keys on linked CI
occurrences.

Revision 4 of `docs/macos-ci-signal-integrity-framing.md` records
implementation findings, not a new design round: §4's acceptance is
unchanged and was approved at revision 3. Two of the four findings
correct this document.
- **§1.3 named the right window and the wrong assertion.**
`leader=exited(signal SIGUSR1)` is rendered only on a FAILED `kill`,
and the USR1 cannot be the call that failed — it is the call that did
the killing. The failing call is the SIGTERM that follows, so
`.expect("TERM delivers")` is what blew up, not the `Running` state
check; `ProcessState` never carries that value and nothing ticks
between the two calls. The row's fragment and mechanism were both
right. Why a group-directed TERM found no group is NOT established
here, and the fix does not depend on it.
- **§1.5 scoped the fix one function too narrowly.**
`wait_for_published_file` gates the real-TUI smoke on the identical
predicate. §1.5's note about the bottom-panel helper is about a
different file and correctly refuses creep there; it does not reach
this one.
- The fixture also had an unnamed second dependency: these signals are
group-directed, so a forked `sleep` is an untrapped group member, and
survival depended on bash and dash suppressing the fork for the last
command of a `-c` script.
- R2's witness could not reproduce the row on Linux, so it widens the
pre-trap window deliberately and proves survival by exit disposition
rather than by an absence observed within a window.
`docs/ci-red-signatures.md` gains the sentence R3 needs most: **R2's
retirement does not touch it and must not be read as touching it.** The
hardening changed a fixture and no product code; the same
group-directed `kill` runs. Because the fixture changes the shape of the
signalled group, a change in how often R3 appears would be evidence
about FREQUENCY, not about cause — and its retirement is still a
diagnosis by the process-signal / reap-ledger lanes.

Stage 2 of `docs/macos-ci-signal-integrity-framing.md` revision 3
(acceptance 6–9). Two test races, both the same shape: the thing waited
for was weaker than the thing asserted, so the wait could return inside
the window the assertion needs closed.
R4 — `wait_for_file` returned as soon as `fs::read` succeeded, which
succeeds on a ZERO-BYTE FILE. The probe publishes with
`open(path,'wb').write(b'1')` and `open()` creates the file before
`write()` fills it, so the helper handed `[]` to a caller asserting
`== b"1"`. It now takes the expected bytes and waits while the file
holds a STRICT PREFIX of them — the states a write in flight can be
observed in — returning anything else immediately so the caller's
`assert_eq!` stays the discriminating assertion rather than becoming a
timeout inside a helper that does not know what was expected.
All four callers pass their expectation. `wait_for_published_file`, one
function away in the same suite, gated the real-TUI smoke's
`assert_eq!(…, b"1")` on the identical predicate and is fixed with it:
leaving it would have let R4 recur under a different selector, which the
registry would then have had to judge a new incident.
R2 — the USR1 fixture waited on `ProcessEventKind::Started`, emitted at
SPAWN, not when `/bin/sh` has parsed `trap '' USR1`. SIGUSR1's default
disposition is terminate, so a signal inside that window kills the
child. The child now publishes a marker AFTER the trap and the test
waits for that marker's CONTENT (the same zero-byte trap applies to a
shell's `>` redirection). `exec` replaces the forked `sleep`, so the
group holds exactly one process and the ignored disposition survives by
POSIX rather than by the shell's fork-suppression optimization — an
unstated dependency the old fixture had, since these signals are
group-directed and a forked `sleep` is an untrapped group member.
Four witnesses, each verified by REVERTING the fix and observing the
failure rather than by reasoning about it:
- `wait_for_file_does_not_return_a_zero_byte_readiness_file` fails
`left: []`, `right: [49]` — R4's two required fragments, verbatim;
- `wait_for_file_does_not_return_a_partial_write` fails on the torn read
a length check alone would admit;
- `wait_for_file_returns_divergent_content_rather_than_timing_out` fails
against an over-strict helper that waits for an exact match;
- `usr1_readiness_waits_for_the_trap_not_for_the_spawn` fails
`left: Some("SIGUSR1")`, `right: Some("SIGTERM")` with the readiness
wait removed. Its fixture sleeps before `trap` so the pre-trap window
is deliberate rather than load-dependent, and it proves survival by
the child's EXIT DISPOSITION rather than by an absence observed within
a window.
R1 is NOT touched — referred to the async-runtime lane (Q#MCI3), because
widening its budget would make it pass and measure nothing more. R3 is
NOT touched and remains UNRESOLVED, owned by the process-signal /
reap-ledger lanes.
`docs/ci-red-signatures.md` moves R2 and R4 to a "Retired rows" section
with their dispositions and adds the rule the file needed and lacked: a
red matching a retired row is a RECURRENCE that puts the retirement in
question, never a known flake. `docs/active-work.md` carries this lane
from its first commit rather than after review asks for it.
Repetition sets, not single runs: the two `--lib` process tests 15/15,
the whole `vterm_stage2_acceptance` suite 15/15 at default parallelism.

Three corrections.
"NO OCCURRENCE WAS EVER OBSERVED" OVERSTATED WHAT THE AUDIT CAN SAY.
Someone may well have seen one of these fail and simply not recorded it;
what is established is the absence of a RECORD. The framing now says
"linked or captured" and states the distinction explicitly, because an
audit that claims to know what nobody saw is making the same kind of
unfounded assertion this lane exists to remove — one level up.
A missing closing quotation mark in acceptance 3.
THE LANE CHECKPOINTED THE REVIEWED HEAD, WHICH GOES STALE ON THE NEXT
PUSH — the exact mechanism by which #171 became invisible while it
drifted 153 commits. Recording one head is a snapshot; what a resume
ledger needs is the sequence. It is now a table of head -> CI run ->
result, newest last, with the rule stated: the branch tip is
authoritative over any row, verified by `git rev-parse`, because the
table is written by hand and the tip is not.
Verified: fmt, diff-check.

Five corrections, one blocking.
BLOCKING — the contract, not the implementation, was what needed
changing. Revision 2's acceptance 3 offered a binary: carry an incumbent
in with a signature and evidence, or remove it as never substantiated.
Stage 1 shipped a THIRD state because both incumbents are neither. The
framing is now revision 3 and names all three states, because a
governing criterion that says "two" while the branch does five is the
framing describing something that does not exist.
"MECHANISM NAMED" OVERSTATED THE EVIDENCE, and the phrase is retired.
The a33 audit proves an assertion string exists; the m6_8 audit proves a
test is timing-based. NEITHER ESTABLISHES A FAILURE MECHANISM — no
occurrence was ever observed, so nothing is known about how, or whether,
either fails. They are now AUDIT NOTES A1/A2 rather than registry rows,
with `R`-numbers reserved for signatures carrying linked evidence. The
distinction is not row-versus-weaker-row: a row says "this was seen,
here is the evidence", a note says "someone recorded a belief and no
occurrence backs it". Both remain unmatchable, so a red in either test
is a new incident.
R2's SIGNATURE WAS WEAKENED AND IS RESTORED. Splitting
`leader=exited(signal SIGUSR1)` into `leader=exited(` plus `SIGUSR1`
would match a child that exited by some OTHER disposition while SIGUSR1
appeared elsewhere in the output — precisely the name-style
over-matching this registry exists to refuse, reintroduced one level
down as fragment-style over-matching. It is one exact fragment again,
and the row says why.
THE HANDOFF STILL ISSUED LIVE IMPERATIVES. Its historical block opened
with "rerun isolated before treating a sweep failure as a regression"
and closed with "rerun the test alone before investigating", so the
supersession note I added sat between two instructions it contradicted.
Both are rewritten as record: the block now reports what that lane
OBSERVED, and the retired instruction is marked retired with its reason
— an isolated green reproduces nothing about a load-sensitive failure.
#215 HAD NO LANE, in the file that requires one for every open PR and
records why: #171 drifted 153 commits while invisible there. That is the
same defect, caught in review rather than 153 commits later. The lane
now carries branch, base, PR, reviewed head, what Stage 1 ships, the
verification, what Stage 2 owes, and the recovery worktree command. Both
snapshot headers are bumped.
Also narrowed a claim the PR body overstated: the registry is NOT
macOS-only. All four EVIDENCED rows are macOS, which is a property of
these occurrences; A1's job is `GPU Render (headless)`, which runs on
Ubuntu, and A2's job was never recorded. A future row from any job
belongs in the same table.
Verified: fmt, diff-check, clippy, --lib 1896, --lib --features crdt
2081.

Stage 1 of the macOS CI signal-integrity lane. `docs/ci-red-signatures.md`
is now the single authority for judging a red CI run.
NOT NAMED "FLAKES", DELIBERATELY. One of its rows is a possible product
defect, and a filename calling it a flake would confer immunity the
evidence does not support.
A ROW MATCHES ON SIGNATURE, NEVER ON TEST NAME. All three of selector,
job/flavor and every required fragment must hold. Fragments are
normalized rather than pasted: PIDs, elapsed times and rendered
OS-error suffixes vary between runs, so a verbatim key would match
nothing, and where a fragment lists alternatives (ESRCH / "No such
process") those are one condition rendered differently by platform. A
failure in a listed test WITHOUT that row's fragments is a new incident.
The process test is why that rule exists: it produced TWO signatures
with different mechanisms and different causal status, and only one is a
test bug. Four incidents, three tests, four signatures — the registry
counts signatures.
THE RERUN RULE IS REPLACED, NOT SOFTENED. A green rerun establishes
INTERMITTENCE ONLY — never environmental cause, harmlessness, or
retirement. The same signature again is a second occurrence and stays
blocking pending investigation or a merge-base control. A different
signature is a new incident.
RETIREMENT IS CAUSAL. A test race retires by hardening that removes the
mechanism plus a discriminating witness; a measurement-design row by its
owning lane replacing or justifying the measurement; an unresolved row
by diagnosis and disposition. Main-branch greens accumulate as
occurrence evidence and retire nothing.
THE AUDIT FOUND A THIRD CATEGORY the framing's acceptance 3 did not
anticipate. It said each incumbent is either carried in with a signature
and evidence, or removed as never substantiated. Both incumbents are in
between: the tests are real and the mechanisms plausible — a33's "blue
pixels" is a genuine assertion string at pmacs-gpu/src/main.rs:17973,
and m6_8 exists and is timing-based — but NEITHER HAS A LINKED
OCCURRENCE. Deleting them would discard a real observation; carrying
them as peers of the evidenced rows would grant exactly the reputation
this lane exists to deny.
They are recorded as "mechanism named, no occurrence recorded", with it
stated that nothing there confers known-flaky status and that a red
matching one is a FIRST recorded occurrence to be investigated. R6 goes
further: with no signature ever captured it CANNOT BE MATCHED AT ALL, so
a red in that test is a new incident by default. That is the correct
outcome for an entry that never carried evidence.
LIVE POLICY IS CENTRALIZED; HISTORICAL EVIDENCE IS NOT MOVED. The
handoff's hazards rule becomes a pointer. Its landed-lesson block at
§5 keeps its own evidence and gains a note that the registry's rerun
rule supersedes "rerun isolated". active-work.md's two mentions are
verification records for the reap-ledger and bottom-panel lanes and are
left alone; only the CI-weakness block's triage half points at the
registry, because the job-cost question there is genuinely separate.
Verified: fmt, diff-check, clippy with and without crdt, --lib 1896,
--lib --features crdt 2081, pmacs-protocol 19, m4 149, required GPU 221.
All three tests the registry names pass locally on Linux, which is
consistent with every row being macOS-only and is not evidence about
any of them.
Docs only. Stage 2 (hardening) is a separate PR.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Define signatures as normalized selector/job/output matches, preserve
historical evidence while centralizing live triage policy, and replace
green-run retirement with causal disposition.
Also fix the rerun-rule contradiction and move the questions out of the
inline-math namespace.
Four red CI incidents across #213 and #214 were each judged "not caused
by this PR", and #214's case is airtight: it is docs-only and its tree is
byte-identical to a green main. THAT PROVES THE PRs DID NOT CAUSE THEM.
It does not prove they are harmless environmental noise, and three of the
four have a specific, findable mechanism. This lane separates those two
claims, which the current process conflates.
FOUR INCIDENTS, THREE TESTS, FOUR SIGNATURES. The registry counts
signatures, not test names, because the process test alone produced two
with different mechanisms and different causal status — collapsing them
under one name is how a possible product defect acquires a flake's
immunity.
1. supersede_cancels_in_flight_job_within_50ms —
"supersede did not cancel within 50ms". MEASUREMENT DESIGN. Its
premise is a 15ms sleep asserted-by-comment to mean "the worker
picked the job up"; on a loaded runner it may not have, in which
case the test measures the QUEUED path while claiming the running
one. And the 50ms clock starts before the second dispatch and is
consumed by the test's own tick+sleep pump, so the measured
interval is dominated by when THE TEST got scheduled. Widening the
number would make it pass and measure nothing more.
2. a_successful_signal_disposition — "leader=exited(signal SIGUSR1)".
TEST RACE. Readiness is ProcessEventKind::Started, emitted at
SPAWN, not when /bin/sh has installed `trap '' USR1`. USR1's
default disposition is terminate, so a signal in that window kills
the child. The fixture's own comment states the requirement it does
not enforce.
3. a_successful_signal_disposition — "EPERM,
measured_group=unobservable(ESRCH), leader=live". NOT a test race:
the group-target behaviour #176 and #200 circled and the
reap-ledger lane parked disposition changes pending. Recorded
UNRESOLVED, POSSIBLE PRODUCT DEFECT, with a diagnosis — never a
green rerun — as its retirement condition.
4. terminal_escape_gates — "left: [], right: [49]". TEST RACE.
`wait_for_file` returns as soon as `fs::read` succeeds, which
succeeds on a ZERO-BYTE file; the probe's `open()` creates the file
before `write()` fills it. The predicate is "readable", the
assertion is "contains 1" — the same shape as signature 2, fixable
at the helper so every caller inherits it.
THE EXISTING PROSE IS DUPLICATED AND KEYED BY NAME. Flake claims live in
at least six places, disagree in detail, carry no signatures or evidence
links, and the handoff's list names three tests — two of which are not
among these four incidents, while three of the four are absent from it.
A list that is both stale and incomplete is worse than none: it confers
"known flaky" on whatever happens to be named and withholds it from
everything else. Acceptance 3 therefore AUDITS the existing three: each
is carried in with a signature and evidence, or removed with a note. No
entry survives on reputation.
The rerun rule is REPLACED rather than softened: one rerun reproducing
the SAME signature is evidence of intermittence only; a DIFFERENT
signature, or the same one twice consecutively, requires investigation
or a merge-base control before the red is attributed to the environment.
Quarantine, if hardening fails, is a separate STILL-BLOCKING CI step —
never #[ignore], continue-on-error, or silent retry-to-green. A
quarantine that stops failing the build is a deletion with extra steps.
Framing only. Sequencing is registry first, hardening second, per
review.

Rule 4 removes a lane when its ARC is done AND its durable facts are in
docs/agent-handoff.md. Both hold: #213 merged, and §1 carries the five
facts Stage 3 produced. The lane goes; the distribution and CI-CRDT
lanes stay, rewritten, because each keeps named follow-ons.
The canonical base and the RECOVERY FLOOR both advance to f186253. The
floor moving with the base is this file's own rule, and the reason is
worth restating: a check that accepts an older commit than the declared
base passes on a tree the rest of the file does not describe. The three
places that named cfc1710 — the base line, the prose, and the `git log`
verification step — now name f186253 together, because a floor that
advances in one place and not the others is worse than one that does not
advance at all.
TWO CI WEAKNESSES STAGE 3 EXPOSED, recorded in the crdt lane that owns
that job rather than lost with the lane being retired:
* CI does not pass --no-fail-fast, so a multi-suite break reports as a
single-suite one. #213's first crdt failure showed ONE suite where a
local --no-fail-fast sweep of the same tree showed THIRTEEN. The
Stage 3 census hit the identical trap and recorded it; CI has it
too.
* The crdt job pairs the heaviest build — lavapipe, full workspace
with crdt, the largest test count — with real-PTY smokes on
5-second deadlines. #213 saw two different such suites fail on two
runs of the same commit; one was a real regression, the other was
load. That ambiguity is the actual problem: a job where noise and
signal look alike trains people to rerun rather than read.
Neither is a defect and neither is fixed here. They are decisions about
what the crdt job should cost, and they belong to whoever picks that
lane up.
Two ops lessons move to the handoff §5, both learned the expensive way
on #213:
* A LOCAL SWEEP IS BLIND TO WHICHEVER FEATURE CONFIGURATION IT DOES
NOT BUILD. Stage 3's census and every verification sweep ran
`--features luajit` without `crdt`, so compile_mode_crdt_acceptance
reached CI broken. Sweep both configurations before calling a corpus
green.
* "MY CHANGE MADE THIS FRAGILE" IS A DIFFERENT FINDING FROM "THIS WAS
ALWAYS FLAKY", and only one of them is yours to fix. Two CI runs on
one commit failed different PTY/GPU suites — the load-sensitivity
signature, on suites the flake list already names. The tell that it
was neither: the failures kept landing on GPU TERMINAL tests, and
terminal placement was what the PR changed. Ask which tests and why
those, before reaching for a rerun.
Docs only.

Stage 3 review round 2. `vterm_stage3_acceptance`'s three terminal
fixtures opened with no `display`, so the flip placed them in a 12-row
panel — and this suite measures RENDERED FRAMES and CHILD PTY GEOMETRY.
It was measuring the geometry the flip had changed underneath it.
I nearly recorded this as a flake, and the reasoning that stopped me is
worth keeping. Two CI runs on the same commit failed DIFFERENT suites:
the first `vterm_stage2`'s real-TUI smoke, the rerun `vterm_stage3`'s
a37 plus two GPU terminal tests. Different failures across runs is the
load-sensitivity signature, both suites are on the documented flake
surface, and the ledger says a red a37 is "ambiguous by construction".
Every indicator pointed at noise.
But the tests it kept landing on were GPU TERMINAL tests, and terminal
placement is exactly what this PR changed. Checking rather than
concluding: all three `terminal.open` fixtures omitted `display`. So the
flip did reach them. It did not BREAK them — they pass locally, and they
passed in one CI run each — it made them MARGINAL, by shrinking the
window whose rendered output they assert against. Marginal under
lavapipe on the heaviest job in the workflow reads exactly like a flake
until you ask which tests, and why those.
The distinction that matters: "my change made this fragile" is a
different finding from "this was always flaky", and only one of them is
mine to fix.
These take the explicit opt-out for the same reason `vterm_stage2`'s
smoke already did — their subject is rendering, geometry and input
round-trip over a full document window, not placement, which the panel
suites cover. The reason is stated at each fixture rather than once at
the top, because each asserts a different property of the geometry.
Verified: vterm_stage3 9/9 with a37 taking 4.33s rather than the 0.17s
that means it never ran; vterm_stage2 6/6; and the full crdt sweep at
3718 passed / 0 failed against a measured 3715/0 baseline, the +3 being
this PR's new pins.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
P1 — compile_mode_crdt_acceptance was never revised. Its three
`compile.run` fixtures still omitted `display`, so the flip placed
output in the panel with `select = false`, the source buffer stayed
active, and `adopt_next_buffer` timed out waiting for a snapshot that
only arrives via the ACTIVE-BUFFER-FOLLOW path. Its subject is CRDT
convergence of a generated buffer, not placement, so it takes the
explicit opt-out — and the reason is recorded at `adopt_next_buffer`,
the helper that actually depends on it, rather than at each call site.
WHY MY OWN VERIFICATION MISSED IT, which matters more than the fix: the
Stage 3 census and every sweep I ran used `--features luajit` WITHOUT
`crdt`, so no crdt-gated suite was ever exercised. The census was
therefore blind to an entire configuration by construction, in exactly
the way #209 exists to prevent. The CI crdt job — added by that lane —
is what caught this, three days after it landed.
Baselined rather than assumed. A worktree at the branch base 21de0b2
sweeps 3715 passed / 0 failed under `luajit,crdt` with
PMACS_REQUIRE_GPU=1; the branch with this fix sweeps 3715 / 0. Identical.
An earlier branch sweep, taken before this fix, reported SEVENTY
failures across THIRTEEN suites. Twelve of those suites — m5_5,
gpu_invocation, gpu_initial_target, m10_11, vterm_stage3 and the rest —
are daemon, socket or GPU suites, and all of them recovered by fixing
three compile tests. The likeliest reading is that the failing
compile-crdt runs leaked daemon or PTY processes that poisoned every
subsequent socket-based suite; what is ESTABLISHED is narrower and
still useful: baseline green, branch green with the fix, and the
collateral confined to process-spawning suites. Count failures, not
causes — the same lesson this stage already learned once, at a
different layer.
Also of note: CI reported only 3 failures because `cargo test` halts
after a failing binary. The workflow does not pass `--no-fail-fast`, so
CI under-reports a multi-suite break exactly as my first census did.
P2 — builtin/runtime/compile.lua's recompile comment still said `_last`
stores only cmdline/cwd. This PR deliberately stores `display` too, so
an explicit opt-out survives replay. Corrected, with the
`display_omitted` arm's remaining purpose stated rather than implied.
P2 — the framing's §7 step 2 still called the resolver extraction
"provably behaviour-preserving", contradicting §1.6b's own record of the
intentional non-string normalization. It is DEFAULT-PRESERVING WITH ONE
INTENTIONAL NORMALIZATION, and now says so where a reader following the
branch plan will hit it.
Verified: fmt, diff-check, compile_mode_crdt 3/3, compile_mode 73/73,
and the full crdt sweep at 3715/0 against a measured baseline of 3715/0.

Branch-plan step 6. The lane, the handoff, COHERENCE, and the framing all
still described Stage 3 as ahead.
COHERENCE §14's scorecard row and §20's Priority 5 both said the adopter
default flip was what remained on the panel. It is done, so the panel
half of P5 is closed and the TREE PRIMITIVE becomes the arc's successor —
§14 grades Tree ✗, and DAP's variables view is its next would-be
inventor. That sequencing is now stated where the next framing doc will
read it rather than living in a conversation.
The lane is RETAINED, not removed, because the PR has not landed; rule 4
removes it once Stage 3 merges and its facts are in the handoff. Both
conditions are half-met, and recording that honestly is cheaper than
discovering later which half.
Five durable facts move to the handoff §1, each of which cost a review
round or a defect to learn:
* A VISIT FROM A PANEL MUST NEVER USE THE RAW SWITCH.
`pmacs.window.switch_buffer` replaces the buffer in the ACTIVE
window, so from a panel it clobbers the panel itself. Q#BP11c is the
contract: after RET, `M-,` must FOCUS the still-present panel rather
than clone its buffer into the document — and an assertion on the
active buffer NAME alone cannot distinguish those two outcomes.
* AN OPT-OUT THAT DOES NOT SURVIVE REPLAY IS NOT AN OPT-OUT. Anything
that replays a stored invocation must store the escape hatch with
it, or the escape hatch is a one-shot that silently reverts.
* Compile's chords are PANEL-LOCAL, deliberately, and `M-x
compile.kill` still reaches the slot from anywhere. A global chord is
a command-surface decision framed separately.
* Two `q` mechanisms coexist by design — presentation history chains in
the side slot; `p.prev` prevents raw-switch and capability-fallback
loops. Neither supersedes the other.
* A CAPABILITY FALLBACK MUST STRIP THE QUIT ACTION TOO, not just the
side parameters. A quit action stranded on a document window makes a
later `q` try to restore a presentation that never happened.
The framing reaches revision 4 with the three defects the flip exposed
(§1.7a–c) and the census lesson (§1.6d): it counted FAILURES, not
CAUSES, and the two differed by an order of magnitude — thirteen listview
failures were one missing frame-geometry declaration. Read a census as
"how many assertions move", never "how many decisions are required".
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Stage 3 step 5, criterion 5 — the one the framing named as most likely to
be quietly wrong.
`acc14` already proves capability fallback for an EXPLICIT `request.side`
at the core level, and it is not this case. Stage 3 resolves the default
into a PANEL REQUEST inside the adopter, so a pre-panel semantic frontend
now has to degrade a request the caller never wrote. Nothing in
`listview.open { name, rows }` says "panel", yet the request reaching the
core does — which is exactly why this is invisible from the adopter's
side and needs its own pin rather than an inference from acc14.
Asserts the three things that must survive the degradation: no side
window, no side parameters on the document window, and NO QUIT ACTION
left behind. That last one is the subtle half — a quit action stranded on
a document window would make a later `q` try to restore a presentation
that never happened.
Bite-verified rather than assumed: flipping the fixture's frontend to
`panel_capable = true` fails it on "a pre-panel frontend gets no side
window from the omitted default", so the test is measuring the
capability and not merely the absence of a panel it never asked for.

Stage 3 steps 3 and 4. Omitting `display` now resolves to the PANEL for
listview, compile and terminal; dired keeps `"current"`, passed
explicitly to the shared resolver. Per-adopter `select` per Q#BP12:
listview true, compile false (passive output must not steal document
focus), terminal true.
The census predicted 37 failures across 5 suites and the flip produced
exactly that — same suites, same per-suite counts. The measurement was a
prediction, not an estimate, which is what the inverted step order was
for. Final sweep: 3449 passed / 0 failed against a 3447 baseline, the
+2 being new pins.
THE CENSUS COUNTED FAILURES, NOT CAUSES. Thirteen listview failures had
ONE root cause: a panel is derived-hidden while frame geometry is
unknown, and listview_acceptance never declared any — it never needed to
while listview defaulted to the current window. One helper took it from
13 to 2. The same applied to m4 and vterm_stage2. Geometry is
authoritative state and a grid frontend's real frame size IS its
declaration; the panel suites have always said so.
THREE DEFECTS THE FLIP EXPOSED, each fixed rather than tested around:
1. The OUTLINE panel's `on_visit` used `pmacs.window.switch_buffer` —
the RAW switch, which replaces the buffer in the ACTIVE window. That
was harmless while the outline opened into a document window. Once
the panel became the default the active window WAS the outline panel,
so RET clobbered the panel with the source and left nothing for `M-,`
to return to. The references panel was migrated to `display_file`
when the arc landed; the outline was missed because nothing exercised
it from a panel until now. Q#BP11c names this exact corruption, and
both the outline and compile tests now assert `M-,` FOCUSES the
panel rather than cloning its buffer into the document — an
assertion the previous one could not distinguish.
2. `pmacs.compile._last` stored only `{cmdline, cwd}`, so a recompile
reached `start_run` with no `display` and took the new default. A
user who ran `compile.run{display="current"}` would be moved into a
panel the moment they pressed `g`. An opt-out that reverts on the
next recompile is not an opt-out; `display` is stored and replayed,
with nil kept as nil so an omitted value still resolves to the
default rather than freezing at the first run's resolution.
3. `opts.display` on a nil `opts` — my own regression, introduced by
fix 2 and caught by `journey_acceptance`, which is exactly what that
ratchet is for.
COMPILE'S CHORDS ARE NOW PANEL-LOCAL, and that is a contract rather than
an accidental reachability loss. Every compile chord is bound
`scope = "buffer"`, so with `select = false` none dispatch from the
document — `C-c C-k` included. `acc34` pins it, and pins that
`M-x compile.kill` still reaches the running slot from anywhere via its
`or compile_slot()` fallback. A global chord is a command-surface
decision and belongs in its own framing.
TEST CLASSIFICATION WAS PER TEST, NOT PER SUITE. Two neighbouring
compile tests land on opposite sides: acc15 (RET-visits-error,
jump-back) asserts the NEW default, while acc16 (n/p within compile
output) genuinely needs the buffer selected and says so. compile's
suite-wide helper opts out because ITS subject is compile-BUFFER
behaviour; the placement-subject tests use a second helper that takes
the default. Every opt-out states why. Nothing was mass-added to make a
suite green.
s1_12's two concerns are split as directed: it keeps its Q#GB18
name-keyed-identity bite with explicit `display = "current"`, isolating
the buffer-level `p.prev` skip rule, while a new `s3_1` pins the
side-window presentation chain — C → B → A → delete, ending at the
document with the wrapper collapsed. The mechanisms are complementary:
presentation history chains in the side slot; `p.prev` prevents
raw-switch and capability-fallback loops.
Verified: fmt, diff-check, clippy with and without crdt, --lib 1896,
--lib --features crdt 2081, pmacs-protocol 19, m4 149, required GPU 221,
and the full serialized sweep at 3449/0.

Review finding P1: Stage 3 was neither portable nor accurately
recoverable. `bottom-panel-stage3` had no upstream and no
`githubsucks/` ref, while docs/active-work.md still described Stage 3 as
"not started" — so a reader on another machine would have found a lane
claiming nothing existed, and no way to fetch the two commits that did.
That is precisely the failure this ledger records as its own rule:
"When a PR is opened, give it a lane", learned when #171 drifted 153
commits while invisible here. A branch without a PR is the same hazard
with less warning.
The lane now carries branch, base, the two completed steps with their
hashes, what remains, the verification at this head, and a recovery
command.
Review finding P2: the framing retained state the census superseded. It
still said "Nothing has been implemented or measured" and that the
blast-radius measurement "has not been taken", directly contradicting
§1.6b two screens below. Both bullets are rewritten to point at the
measurement rather than deny it, and the dired question is marked
DECIDED rather than left open.
Also records, in both documents, the thing step 2's original commit
message overstated: it is DEFAULT-PRESERVING WITH ONE INTENTIONAL
NORMALIZATION, not "behaviour-preserving". Every adopter kept its
default and the suite is byte-identical to baseline, but terminal's
invalid-input behaviour moved on purpose — and the sweep could not have
caught it, because every existing assertion passes an unknown STRING,
which takes the same path under both designs.

Stage 3 step 2 (Q#S3-1). DEFAULT-PRESERVING WITH ONE INTENTIONAL
NORMALIZATION — not "behaviour-preserving", which would be too broad a
claim. Every adopter keeps its current default, and the full serialized
suite is 3447 passed / 0 failed with ZERO suites differing from the
pre-change baseline. But invalid-input behaviour DID move, deliberately,
and that is pinned rather than asserted in prose.
Before this, FOUR adopters validated the same three-value vocabulary in
four places: Rust for the terminal, and hand-written Lua copies in
listview.lua, compile.lua and dired.lua, each carrying its own copy of
the error string. `parse_adopter_placement` read like the shared parser
its doc comment implied but had exactly one caller. Four copies of one
rule is how the next adopter gets it subtly wrong, and the next adopter
is DAP.
`resolve_adopter_display(operation, raw, default)` now owns exactly
three things: the vocabulary, the error text, and the default policy.
Reachable from Lua as the internal seam `pmacs.window._resolve_display`.
THE DEFAULT IS A PARAMETER, NOT A CONSTANT, and that is load-bearing
rather than stylistic. listview/compile/terminal will resolve omission
to the panel in step 3; DIRED MUST NOT, because
`pmacs.path.set_directory_handler` calls it with `{ dest = dest }` and
no `display` key at all — a flipped default would open `pmacs .` in a
bottom panel. Passing the default in makes dired's exemption visible at
its call site instead of hidden in a divergent copy.
TERMINAL'S `window` MUTUAL-EXCLUSION STAYS IN ITS OWN WRAPPER. Only the
terminal accepts a `window` id and only it must reject `window` combined
with `display = "panel"`. A helper pretending the four parsers were
identical would be its own defect.
THE NORMALIZATION, DECIDED AND PINNED. Terminal read
`get::<Option<String>>("display")?`, so a non-string value raised mlua's
TYPE error before reaching any custom message, while the Lua copies
stringified it into their own. Nothing pinned either behaviour — every
existing assertion passes an unknown STRING, which takes the same path
under both designs and therefore could not have caught a regression
here. The custom error wins because it names the legal vocabulary; the
value is rendered by TYPE ALONE (`unknown display (integer)`) so the
message cannot imply a string was passed.
Pinned at the terminal entry point in acc19 — the one adopter whose
behaviour changed — asserting the shared error AND that nothing is
created. The type SPELLING is deliberately not pinned: Lua 5.4 says
`integer` where LuaJIT has no integer subtype, so asserting either
literal would pass on one CI flavor and fail on the other. Verified
46/46 under both.
COMPILE NEEDED AN EXPLICIT OMISSION CAPTURE, and finding that out is
what this step is for. The resolver collapses omission into its default,
but compile's recompile gate distinguishes them: it fires on OMISSION
only, never on an explicit `display = "current"`, which is the
documented opt-out and must reach the raw switch even when the previous
run was panel-placed. Resolving first and testing `== "current"`
afterwards would have silently merged the two and broken the opt-out
with every test still green. `display_omitted` is captured before the
resolver call and the gate keys on it.

Branch-plan step 1, whose whole point is that it precedes the flip. The
throwaway edit is NOT in this commit; only the measurement survives it.
A CENSUS THAT STOPS AT THE FIRST FAILING BINARY IS NOT A CENSUS. The
first sweep reported 2 failures in 1 suite and looked comfortingly
small — `cargo test` halts after a failing test binary, so everything
alphabetically past bottom_panel_stage1_acceptance never ran. With
--no-fail-fast the real figure is 37 failures across 5 suites. Any
re-measurement must pass that flag or under-report by an order of
magnitude, which is the same silent-success shape this arc keeps
finding.
M4_ACCEPTANCE WAS PREDICTED BY NOBODY — not the parent framing, not
Q#BP12's adopter table, not revision 1. Its two failures are the LSP
hover and outline panels, which are LISTVIEW CONSUMERS, so flipping
listview's default reaches the LSP suite transitively. Q#BP12's four
rows are the DIRECT population; the real one is everything built on
listview. That is the intended behaviour, but the map has to say so or
the next listview-based feature inherits a default nobody documented.
THE PROPORTIONS INVERT THE OBVIOUS READING. compile_mode has the most
failures (17) and the least placement content — process-lifecycle and
styling tests that merely use compile and now find its output
elsewhere. listview_acceptance has fewer (13) but loses THREE QUARTERS
of its suite, and its failures are placement in substance.
Classification decided per test, not per suite, because two
neighbouring compile tests land on opposite sides: acc15
(RET-visits-error, jump-back) is placement — Q#BP12 explicitly requires
panel → RET source → M-, back to the still-present panel with the
document window intact — while acc16 (n/p walk within compile output)
genuinely needs the compilation buffer selected and takes an explicit
display = "current". A sweep classifying per suite would have got both
wrong.
Both M4 failures are placement-subject: outline_panel_opens_visits_and_
restores is almost a direct realization of criterion 58 (open → visit →
jump-back → quit), and hover_doc_panel keeps the omitted default while
asserting the new placement plus its existing content and quit
guarantees. Neither takes display = "current".
Tree verified clean after revert: the three default-resolution branches
are unchanged on disk.

Arc 7's last step. Stages 1, 2A, 2B-1, 2B-2 and 2B-3 are all on main;
the panel is complete on both frontends and every mechanism this stage
needs exists. What remains is the decision the arc deferred on purpose:
omitting `display` should mean the panel, not the selected window.
Revision 2, approved with amendments. The scout found the parent
framing's plan sound and two of its details drifted.
THE FLIP IS THREE SITES IN TWO LANGUAGES, and a fourth validator that
must not move. `parse_adopter_placement` reads like the shared parser
its doc comment implies but has EXACTLY ONE CALLER, the terminal;
listview and compile each re-implement the same three-value validation
in Lua, including their own copy of the error message. Changing only
the Rust parser would leave both Lua adopters resolving omission to the
current window — a half-flip that looks done and behaves inconsistently
per adopter.
DIRED IS A FOURTH COPY OF THE VALIDATOR AND MUST KEEP `"current"`.
Review caught this; revision 1 had it as a leaning. The mechanism is
specific rather than stylistic: `pmacs.path.set_directory_handler`
passes `{ dest = dest }` with NO `display` key, so `pmacs .` resolves
by omission. Flipping dired's default would open the golden journey's
first directory listing in a bottom panel. The distinction that makes
this principled rather than an exception: listview, compile and terminal
produce output the user CONSULTS; dired produces a document the user
WORKS IN. The panel default is right for the first kind and wrong for
the second.
UNIFY NARROWLY, NOT WHOLESALE. A shared
`resolve_adopter_display(operation, raw, default)` owns the vocabulary,
the error text and the default policy, with dired passing
`default = "current"` so its exemption is a parameter rather than a
divergent copy. Terminal's `window` mutual-exclusion stays in its Rust
wrapper — the parsers are not identical and a helper pretending
otherwise would be its own defect.
One normalization is named rather than absorbed: terminal reads
`get::<Option<String>>("display")?`, so a non-string value raises mlua's
TYPE error before the custom "unknown display" message, while the Lua
callers `tostring()` it into their own. Different observable behaviour
for the same bad input; unifying the error text without deciding this
would silently change one of them.
`select` IS A CORRECTNESS REQUIREMENT, and Q#BP12's citation drifted.
`seat_cursor` is at listview.lua:130, not :64 — :64 is now a name-variant
constant. The constraint holds and is worse than "focus preference":
`seat_cursor` drives `pmacs.editor.move_down()`, which acts on the ACTIVE
window, so an unselected listview panel seats the cursor in the user's
document. That is why the table's `select` differs per adopter —
listview true, compile false, terminal true — and why a uniform value
would look right and break compile's passive output.
TESTS ARE MEASURED BEFORE THE FLIP, NOT AFTER. Two Stage 1 acceptance
tests assert the old default deliberately: acc19 (:1223) opens a
listview with no `display` specifically to seed a DOCUMENT window "so
side-affine placement cannot be vacuous" — the flip breaks its
anti-vacuity guarantee, not merely its assertion — and acc19b (:1308) is
built around a recompile reaching `start_run` with no `display`. The
sweep rule is stated: a test whose SUBJECT is placement asserts the new
default; a test whose subject is compile or terminal behaviour opts out
only when its setup genuinely requires the document window. Mass-adding
`display = "current"` to make suites green would convert a behavioural
change into an invisible one.
Acceptance gains a NEGATIVE criterion (9): omitted `display` still means
document placement for direct dired AND for `pmacs .`. That is the
criterion that catches a well-intentioned "make all four consistent"
change.
Framing only. No code, no flip, no test changes.

Two parts, one intent: record the release, and fix the user-facing
surfaces it falsified.
ABSORPTION. v1.1.0 shipped and nothing recorded it. docs/active-work.md
had no distribution lane, the handoff anchor still named c5f7501, and
COHERENCE.md — a REQUIRED framing input — still asserted "zero release
machinery exists" and graded journey step 1 as source-build-only. Both
are now false, and a framing doc written against them would have been
written against a lie.
* §0 scorecard: step 1 Partial -> Works; §17 Missing -> Partial; the
journey row moves off "steps 1, 11 and 12 remain the thin end" to
name 11 and 12 only.
* §17 ground truth rewritten: what Stage 1 shipped, and the nine
things it explicitly did not.
* §20 Priority 8: "State: zero" -> Stage 1 shipped, with the blocker
it named ("every other priority's value is invisible until this one
exists") recorded as LIFTED. Its next increment is a DECISION about
channels/update/signing, not a queued plan — worth stating so nobody
treats Stage 2 as pre-approved.
* A distribution lane in active-work.md, rewritten-not-removed because
the arc is not done.
Five durable facts move to the handoff §1, each of which cost something
to learn:
* a release build can produce FIVE binaries and three must never ship;
layer-2 exclusion is load-bearing, demonstrated when target/release
still held all three after building only two;
* `env!("CARGO_PKG_VERSION")` expands in the crate being COMPILED, and
three correct tests could not fail while two crates shared a number;
* pin release runners, and assert the glibc floor from the binary
rather than trusting the pin;
* a tag pushed before its workflow reaches the default branch does
nothing, SILENTLY;
* verify from the downloaded artifact, with a negative control — the
1,576 `loro` strings mean nothing without the control build's zero.
STALENESS, found by reading the surfaces a new downloader hits first.
`pmacs --help` claimed the TUI was "currently the only frontend;
reserved for the M4 GUI rollout, where `pmacs` will default to the GUI".
That is not merely dated — it is false in a release that SHIPS the GPU
frontend as a second binary. Rewritten to say what -nw actually does
(name the default explicitly for scripts and wrappers), and --gpu now
states its two real preconditions: a `crdt` build, and pmacs-gpu either
beside the binary or on PATH. Both are things a downloader can get
wrong and neither was documented where they would look.
Also in main.rs: the TLS attach line said "activation in v0.2" and four
doc comments dated themselves "v0.1" or "M4+" while describing behaviour
that is still current. The behaviour claims were accurate; only the
version labels lied, so the labels are gone rather than the sentences
rewritten. One comment gained a correction it needed regardless —
FrontendChoice is IN-PROCESS dispatch and the GPU frontend is not a
value of it, which the old text implied it eventually would be.
README status block: v1.0.0 -> v1.1.0, protocol v20 -> v21, and it
pointed at docs/roadmap-2026-07.md for "current direction" — a file that
opens by calling itself a historical snapshot and redirecting to the
handoff. It now points at COHERENCE.md and the handoff, and mentions the
arcs that landed since it was last touched.
Verified: fmt, diff-check, clippy with and without crdt, --lib 1896,
--lib --features crdt 2081, pmacs-protocol 19, m4 149, required GPU 221,

Operational note for §7's step 5, recorded before it can bite rather
than after.
For `on: push: tags`, GitHub resolves the workflow file AS IT EXISTS AT
THE TAGGED COMMIT, and it registers a repository's workflows from the
DEFAULT BRANCH. Verified while #211 was in review: `gh workflow list`
reports only CI, because release.yml lives on the branch and not yet on
main.
So tagging any commit that predates the merge produces no run, no error,
and no release. That failure mode is worse than a red one: a silent
no-op is indistinguishable from "the run has not started yet", which is
exactly what someone watching for an RC would assume. Cut the RC from
the merge SHA and confirm a run actually appeared before drawing any
conclusion from its absence.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
.github/workflows/ had exactly one workflow and it was test-only: no
release job, no artifact upload, no tags-to-binaries path. Installing
pmacs meant `git clone` plus knowing the feature-flag matrix.
COHERENCE.md §17 grades this "missing — zero release machinery exists";
this moves it to Partial and completes journey step 1.
Scope is one stage: binaries when a `v*` tag is pushed, attached to a
GitHub Release. Channels, rollback, update-in-place, signing, RHEL 9 and
Intel macOS are out of scope and named in the framing's §5.
WHAT SHIPS: pmacs and pmacs-gpu, both at 1.1.0, CRDT-enabled, co-located
in one archive, with SHA256SUMS. pmacs-protocol stays at 1.0.0 — it is
the wire crate and versions on its own schedule.
THE VERSION BUMP EXPOSED A REAL DEFECT, and it is the reason this PR
touches src/ at all. `InstanceIdentity::for_running_process` is defined
in pmacs-protocol and expanded `env!("CARGO_PKG_VERSION")` THERE. `env!`
expands in the crate being compiled, so the field documented as "Pmacs
version string" carried the PROTOCOL crate's version. That identity
reaches Lua as `pmacs.instance.identity()` and goes on the wire in
`Hello`, so a 1.1.0 release would have told every attached frontend it
was 1.0.0.
Nothing could have caught it earlier. Three tests assert
`id.pmacs_version == env!("CARGO_PKG_VERSION")` evaluated in the pmacs
crate — the correct assertion — but while both crates read 1.0.0 they
compared the same number reached by two different paths and COULD NOT
FAIL. Deciding to hold pmacs-protocol at 1.0.0 while moving pmacs is
what made them discriminating; all three failed on the bump. The version
is now a parameter so `env!` expands in the caller's crate. A test can
be correct and still prove nothing when the two things it compares are
equal for a reason unrelated to the code under test.
TWO LAYERS OF BINARY EXCLUSION, and layer 2 is load-bearing —
demonstrated, not argued. Cargo auto-discovers src/bin/*.rs, so a
release build can produce five binaries and three must never ship
(pmacs-audit is a contributor tool; pmacs_fake_lsp and pmacs_fake_mcp
are test fixtures). Layer 1 names explicit --bin targets. Layer 2 stages
an explicit asset list, and building this branch produced exactly the
case it guards: after building ONLY --bin pmacs and -p pmacs-gpu,
target/release still held all three forbidden binaries, left by an
earlier `cargo test --release`. Swatinem/rust-cache restores that kind
of directory in CI. An implementation trusting layer 1 and archiving the
directory would have published a fake language server in the first
release.
The three archive assertions are bite-verified: a smuggled
pmacs_fake_lsp, a missing pmacs-gpu, and a cleared executable bit are
each caught, with the honest archive passing.
THE GLIBC FLOOR IS ASSERTED, NOT TRUSTED. Pinning ubuntu-22.04 sets the
floor at 2.35 (Ubuntu 22.04, Debian 12 — NOT RHEL 9 at 2.34, which needs
a container or cross-build and is parked). But a pinned runner proves
nothing about the artifact, and the failure surfaces as a bare
`GLIBC_2.39 not found` on a user's machine with no clue which commit
caused it. The build reads versioned-symbol requirements out of the
binary and fails above the floor, so switching to ubuntu-latest fails in
CI instead of shipping. Bite-verified both directions on a glibc 2.44
host. Both runners are pinned; macos-latest would drift the minimum
supported macOS with no commit to point at.
Preflight runs before any build: the tag must match the root crate
version (stripping a prerelease suffix, so v1.1.0-rc.1 and v1.1.0 both
match 1.1.0), and the tagged commit must be an ancestor of main. Both
catch mistakes that are cheap now and expensive once a public URL
exists. The suite is not re-run — CI already tested the commit — but
nothing otherwise enforced that a tag points at a tested one.
Verified: fmt, diff-check, clippy with and without crdt, --lib 1896,
--lib --features crdt 2081, pmacs-protocol 19, m4 149, required GPU 221,
and the full serialized crdt sweep at 3,715 passed / 0 failed / 30
ignored — identical to the pre-change baseline, so the protocol
signature change broke nothing. Archive staging, contents, executable
bits and both --version outputs were exercised against a real release
build locally.
No release is cut by this PR. Per the framing's §7 the RC is tagged
after merge, from the merge SHA.

.github/workflows/ contains exactly one workflow and it is test-only.
There is no release job, no artifact upload, no tags-to-binaries path.
Installing pmacs means `git clone` plus knowing the feature-flag matrix.
COHERENCE.md §17 grades this "missing — zero release machinery exists",
and §20 puts it at Priority 8 with the note that every other priority's
value is invisible until it exists.
Scope is deliberately ONE STAGE: binaries when a tag is pushed,
attached to a GitHub Release. Channels, rollback, update-in-place,
signing and first-launch tool detection are out of scope and named in
§5. A baseline, not the arc.
Revision 2, approved with amendments. Two of them corrected revision 1:
THE GLIBC ARITHMETIC. Revision 1 implied that moving off ubuntu-latest
buys reach "several distro generations" including RHEL 9. It does not.
RHEL 9 ships glibc 2.34, which is BELOW the 2.35 floor a pinned
ubuntu-22.04 build sets, so RHEL 9 is excluded by that choice rather
than covered by it. The floor is now stated explicitly with its table,
so a RHEL 9 user reads "not supported yet" instead of discovering a
loader error; supporting it needs a lower-glibc container or
cross-build and is parked.
WHY CO-LOCATION IS REQUIRED. Revision 1 said separating `pmacs` from
`pmacs-gpu` makes `--gpu` "silently fail". Verified against
src/main.rs:304: `gpu_binary` prefers a co-located binary when that path
is_file(), falls back to a bare-name PATH lookup, and on failure names
both — "sibling … is absent and PATH lookup for pmacs-gpu failed". So
the requirement is that a release archive be SELF-CONTAINED for a user
who unpacks it somewhere off PATH, not that failure is quiet.
The load-bearing finding: a release build can produce FIVE binaries and
three must never ship. Cargo auto-discovers src/bin/*.rs, so alongside
pmacs and pmacs-audit it also builds pmacs_fake_lsp and pmacs_fake_mcp —
test fixtures. Exclusion is therefore two-layered, because neither layer
suffices alone: explicit --bin targets so the unwanted binaries are not
produced, AND an explicit staged asset list so the archive's contents
are a decision rather than a directory's residue. Layer 1 alone still
archives whatever a cached target/release holds from an earlier step;
layer 2 alone relies on a list nobody re-checks when a new src/bin/*.rs
appears.
Two facts checked rather than assumed while framing:
`pmacs-gpu --version` already exists (pmacs-gpu/src/main.rs:667) and
prints "pmacs-gpu <ver> (protocol v21)", so asserting both binaries
report 1.1.0 is directly implementable after the bump. And `run_gpu`
refuses a non-CRDT build outright — "pmacs: --gpu requires pmacs built
with --features crdt" — which is a direct citation for shipping CRDT
rather than the inference from capability defaults revision 1 used.
Framing only. No workflow, no version bump, no release.

Two jobs: absorb the CI CRDT coverage lane now that #209 has merged, and
clear documentation drift that predates it and was found while reading
in on a new machine.
ABSORPTION. docs/active-work.md's lane is REWRITTEN, not removed —
rule 4 removes a lane when its ARC is done, and three named follow-ons
remain. It shrinks from 10,441 to 3,037 characters because rule 3 puts
durable architecture in the handoff and leaves only volatile state here.
The follow-ons, each with its reason:
* the macOS crdt leg, deferred pending first-run evidence that NOW
EXISTS and is favourable — the non-crdt macOS legs pass at 3,474,
thirteen fewer than ubuntu's 3,487 purely from cfg-compilation of
the Linux-gated process tests, and no crdt-specific failure appeared
anywhere;
* the --lib --features crdt flake, which did NOT reproduce in #209's
runs — but every run was --test-threads=1 and the trigger was seen
under PARALLEL load, so that is consistent with the drain_until
hypothesis rather than evidence against it. Its own PR: a
product-defect hypothesis, where all of #209 was configuration;
* the crdt_replica serde default, a third default mechanism that
disagrees with the Default impl in non-CRDT builds, untestable
without a self-describing format this crate does not depend on.
Five durable facts move to the handoff §1, each of which contradicted
something previously recorded: gpu-render runs a DIFFERENT PACKAGE than
the suites the old fix-shape wanted moved there; PMACS_REQUIRE_GPU is
absent from two of the four GPU suites; m10_10_perf is a CI-default
tripwire rather than a bench; --keep-going is what makes a clippy run an
inventory instead of a lower bound; and a feature can matter to a crate
a per-test census scores as unaffected.
DRIFT, all of it predating this lane and all found while reading in:
* COHERENCE.md §20's Priority 1 still read "runs to step 5; thin from
step 6" and called Stage 1b-3 "in flight", while §0's scorecard said
step 10 and 1b-3 had landed. §20 is a REQUIRED FRAMING INPUT per
CLAUDE.md, so a stale priority annotation there does not just sit
wrong — it misdirects the next framing doc written against it. Its
arc-cuts list carried the same two errors.
* docs/agent-handoff.md §1 described Discovery Stage 1 and Journey
1b-3 as "IMPLEMENTED, PR open" while §1a, twenty lines above,
correctly recorded both as merged. A file that contradicts itself is
worse than one that is merely behind.
* docs/side-quest-backlog.md, compiled 2026-07-14, listed #123 as an
open PR (merged 2026-07-21), #137 as "in review" (merged), and
HTML/CSS as an unshipped grammar (#146 shipped it AND its injection
consumers). It is the cross-cutting index, so a stale entry sends
someone to build something that already exists. Its north-star
section now says plainly that every original item has shipped and
that the file no longer sets direction — COHERENCE.md §20 and the
handoff §1a do, and both postdate it.
* docs/json-yaml-framing.md's status line advertised "PR #123 open and
awaiting review" for six weeks after that PR merged. Corrected in
the status line only; the revision-4 body is the as-reviewed text
and is left unedited.
No code, no workflow, no protocol change.

Acceptance 8 in its strongest form. The ledger predicted the post-round-2
job totals from the census — 3,766 for Test (crdt) and 3,487 for
Test (ubuntu/luajit) — and run 30706324644 @ 71a1ebd reported exactly
those. Predicting the count before the run and matching it says more
than reconciling one afterwards: a vacuous leg would have landed near
the non-crdt job's figure.
Also records two readings that would otherwise be misread:
The macOS legs report 3,474, thirteen fewer than ubuntu's 3,487. That is
cfg-compilation, not lost coverage — the Linux-gated process tests
(setsid, the `bash -m` job-control corroboration) are not built there
rather than skipped.
And the head_sha trap bit again. Round 1's run (30705916037 @ 6519bc3)
was CANCELLED, not green: round 2's push superseded it, which is the
concurrency group working exactly as its comment in ci.yml describes. A
`gh pr checks` summary polled around that moment reported the PREVIOUS
run's results — with entirely plausible timings — and round 1 was
briefly reported as passing on that basis. This ledger already carried
the lesson from #178 ("verified by head_sha, not by the check summary").
It recurs because the wrong answer looks exactly like the right one, so
it is now recorded against this lane too.

Review finding (P2), and it is this lane's own defect class one level
down. Round 1 added a `-p pmacs-protocol --features crdt` step so that
crate compiles both ways. That step EXECUTED
`InstanceCapabilities::default` in both configurations and asserted
NOTHING about it: the crate's only use of that value is a transport
round-trip, and a round-trip is invariant to the values. An all-false
default — or one whose three fields disagreed with each other — encodes,
decodes, and passes identically in both builds.
Running code is not testing it. That is the same sentence this whole
lane is about, and round 1 committed the smaller version of it while
fixing the larger one.
Three tests now pin the defaults, and the split is the point:
* under `crdt`: multi_frontend, crdt_replica and semantic_render all
default true. Advertising false on a CRDT build would strand every
frontend in single-frontend mode.
* without `crdt`: all three default false. Advertising true would be
wire-protocol false advertising — those code paths are
conditionally compiled out.
* FrontendCapabilities::default is all-false in BOTH builds, and this
test is DELIBERATELY NOT feature-gated.
That third one pins an asymmetry nothing else did.
FrontendCapabilities derives Default and is feature-INVARIANT, while
InstanceCapabilities is feature-DEPENDENT. It is load-bearing rather
than an oversight: an instance advertises what it can do, a frontend
OPTS IN through the negotiation handshake, and a v1 frontend has no
local CRDT state regardless of how the crate it links was compiled.
Making the frontend side track the feature would have frontends
claiming support they do not have. A future edit that "makes them
consistent" now fails a test that says why not to.
All three fields are asserted separately rather than by comparing whole
structs, because they track one `cfg!` and a change flipping only some
of them is exactly the regression worth catching.
Bite-verified rather than assumed: mutating `multi_frontend` to a
literal false gives `FAILED. 18 passed; 1 failed` with the expected
assertion message; restoring returns 19/19. Both configurations now
report 19 tests, up from 17, with the correct cfg-gated test running in
each.
Left untested and recorded instead: `InstanceCapabilities::crdt_replica`
carries `#[serde(default = "default_true")]`, a THIRD default mechanism
that is unconditional and therefore disagrees with the `Default` impl in
a non-CRDT build. Exercising it needs a self-describing format and this
crate's only serde dependency is postcard, which is not one. Adding
serde_json as a dev-dependency to test a divergence this lane did not
introduce is scope creep.
Also corrects a note that round 1 made stale: the ledger's "do not
subtract the two jobs' totals" figures (3,485 and 3,747) were measured
BEFORE round 1 added the protocol step, and round 2 adds two tests to
that crate. Expected totals are now 3,487 and 3,766. The root-package
census is untouched at 3,467 / 3,746 — the new tests live in a sibling
crate, which is precisely the region scripts/feature-census cannot see.
Verified: fmt, diff-check, clippy on pmacs-protocol in both feature
configurations, and workspace clippy --features crdt --keep-going.

Review finding (P2): docs/active-work.md and docs/agent-handoff.md both
still said "PR not yet open". This file's own rule is that an open PR
gets a lane recording its state — "When a PR is opened, give it a lane",
written after #171 drifted 153 commits while invisible here. Both now
carry PR #209, its six commits, and the first CI run.
That run is worth recording rather than merely citing, because it
discharges the one risk the framing could not close locally. ALL 14
CHECKS GREEN, including both new jobs (Test (crdt) 12m20s, M10 Perf
Gates (crdt) 5m40s) and the macOS/luajit leg that is the documented
flake surface. This was the first time in the project's history that
any of these tests executed in CI.
ACCEPTANCE 8 HOLDS AGAINST THE REAL RUN. Test (crdt) reported 3,717
passed / 0 failed / 30 ignored: the 3,746 all-targets census (with
basedpyright NOT skipped, as it is locally) plus one doc test, less the
30 ignored. The job demonstrably compiled and ran the crdt corpus rather
than reporting green over nothing — which was the whole point of writing
that criterion while the local sweep was already green.
A trap for the next reader is recorded with it: DO NOT SUBTRACT THE TWO
JOBS' TOTALS. Test (ubuntu/luajit) reports 3,485 and Test (crdt) 3,747,
a difference of 262 rather than 279, because the jobs run different
SETS — the non-crdt job adds pmacs-protocol's 17 tests. The dark count
is the all-targets comparison, 3,746 - 3,467. The wrong number looks
entirely plausible.
Chasing that discrepancy found a real gap, and one this lane's own tool
could never have surfaced: PMACS-PROTOCOL HAS ITS OWN `crdt` FEATURE.
It gates no tests, so a per-test census reports 17 either way and scores
the crate as unaffected — but it changes `cfg!(feature = "crdt")`
EXPRESSIONS inside InstanceCapabilities::default and
FrontendCapabilities::default, so those same 17 tests exercise different
runtime values under it. CI had only ever run the non-crdt ones. Closed
with an explicit `-p pmacs-protocol --all-targets --features crdt` step,
verified 17/17.
The blind spot is structural, not an omission, so it is documented at
the tool rather than fixed in it: scripts/feature-census censuses the
workspace DEFAULT MEMBER, because that is what a bare
`cargo test --all-targets` builds. Sibling crates are invisible to it no
matter what configs are passed. The durable lesson: A FEATURE CAN MATTER
TO A CRATE A PER-TEST CENSUS SCORES AS UNAFFECTED. Check siblings by
hand.
Verified: ci.yml parses at 10 jobs, script syntax clean, fmt,
diff-check, and the new protocol step green locally.

Framing revision 3, plus the ledger and handoff updates the lane owes.
docs/active-work.md's "NEEDS A LANE" block is replaced rather than
annotated: the lane now has a branch, a framing, an implementation and
verification, so the old text's premise ("no branch, no framing yet")
was the part that needed removing. Its stale figures go with it — the
273-dark reading at 74301d1 and the seven-item clippy list, both
superseded and both explicitly labelled do-not-quote in the new block.
The corrections this lane produced, all now recorded where the next
reader will hit them:
* m10_10_perf is a CI-DEFAULT REGRESSION TRIPWIRE, not a bench. Its
bounds are deliberately generous "to catch catastrophic regressions,
not to verify a tight perf claim", so #[ignore]ing it to give it a
perf job would have reduced coverage inside a coverage lane. The
framing had this backwards through revision 1 and says so.
* gpu-render runs `cargo test -p pmacs-gpu` — a DIFFERENT PACKAGE from
the root-package GPU suites. The long-recorded fix-shape of "move
the GPU-requiring crdt suites onto gpu-render, it already has
lavapipe" does not work as written.
* PMACS_REQUIRE_GPU is not uniform: absent from
gpu_invocation_acceptance and gpu_initial_target_acceptance
entirely, so it cannot serve as blanket proof the GPU suites ran.
* The dark-test classification found THREE dispositions, not two:
benches awaiting a job, deliberately-manual operator tests, and
known-defect markers. Collapsing the second into the first gives a
CI job to tests whose #[ignore] reason says not to.
* §1.1's own target-column claim was wrong, and scripts/feature-census
caught it. Eleven targets run with zero tests under CI's flags;
eight of those gain tests under crdt and three are helper binaries
with no tests in either. The framing had merged two true statements.
Acceptance 9 is revised rather than quietly met at a lower bar. The
planned deliberately-broken-test bite is replaced by the --covers
coverage assertion plus the CI count reconciliation, and the doc states
what that trades: stronger on the claim specific to this lane (the old
job STRUCTURALLY cannot see these tests), and no longer proving that a
failing crdt test turns the job red — which is generic cargo and Actions
behavior, not anything this lane changes.
The handoff gains a census hazard beside the existing sweep note,
because every trap in it was hit while writing the script and one of
them survived two framing revisions: libtest prints `name: test` with no
space before the colon, a zero-test target prints only its Running line,
and both configurations need an --ignored pass or pre-existing ignores
get attributed to the feature.
The ledger also records what is NOT established, which is the lane's
whole remaining risk: the sweep is green SERIALIZED ON A DEVELOPER
MACHINE, and the failures this lane expects are hosted-runner timing and
concurrency. That green removes the "tests are wrong" explanation and
leaves the expected one untested. It must not be quoted as evidence the
CI leg will be green.

docs/active-work.md says the dark-test figure "moves with every merge
and must be re-measured, not quoted." That instruction has never had a
tool, so every re-measurement was a hand-rolled `--list` pipeline
written from scratch.
Hand-rolling it is not safe. Writing this lane's census by hand, the
first attempt filtered libtest's list with `/ : test$/` — but the output
is `name: test` with NO space before the colon, so it matched nothing,
reported zero targets, and looked like a clean run. A census that
silently reports nothing is the same failure class as the dark tests
themselves: no signal, presented as a result.
scripts/feature-census diffs `cargo test --list` between two feature
configurations and reports what the second has that the first cannot
see. Its header records each parsing trap, because every one of them was
hit while writing it:
* `name: test` has no space before the colon.
* `--list` also emits `: benchmark` lines.
* cargo's `Running` lines have two shapes — `unittests src/lib.rs` and
`tests/foo.rs` — so a fixed field index handles one and mangles the
other.
* a target with zero tests prints its `Running` line and nothing else,
so counting only test lines DROPS it from the diff — losing exactly
the finding worth surfacing.
* `--list` includes #[ignore]d tests, which are dark in the same sense
but are NOT recovered by adding a feature to an ordinary test job.
That last one needed a second correction after the script was running.
Counting only B's ignored set attributed pre-existing ignores to the
feature: `rope::tests::perf_smoke_*` are ignored under both configs and
are not "dark and ignored." Both sides now get an ignored pass and the
figure is the difference, which is what turns a flat "279 dark" into
"268 recovered by a plain leg, 11 needing --ignored."
The script also corrected a claim in this lane's own framing doc. The
framing said eight test binaries contain zero tests under CI's flags,
derived from a target-count difference (93 vs 101). The truth is that
ELEVEN targets run with zero tests under those flags; eight of them gain
tests under crdt and three are helper binaries with no tests in either
configuration. Two different true statements, and the framing had
merged them.
Fail-closed on a build failure (exit 3) rather than reporting a census.
A configuration that does not compile yields no test list, which is
indistinguishable by counting from "this configuration has no tests" and
would render as a spectacular and entirely false "every test is dark."
That is not a small error; it is a number that would get quoted.
All five documented exit codes are exercised rather than asserted: 0 on
a clean census and a holding --covers claim, 1 when the claim fails
(both for a test present under both configs and for a misspelled name),
2 on usage, 3 on a configuration that fails to build.

Nothing in this workflow ever enabled the `crdt` feature, so every
`#[cfg(feature = "crdt")]` test was NOT COMPILED — not skipped, not
filtered, not reported. Measured at 4223dd3: 3,467 tests under the
`test` job's flags versus 3,746 with `crdt`. 279 tests had never
executed in CI, and 186 of them are in the library, whose
`cargo test --lib --features crdt` invocation CLAUDE.md lists as a
REQUIRED pre-PR gate. CI had never run a required gate.
Eight test binaries also contained zero tests under the old flags. They
built, ran, and reported `ok` with nothing in them.
This job recovers 275 of the 279. The other four are excluded on
purpose, each for a stated reason rather than left as residue: three are
m10_11_acceptance's PTY-doubled tests, marked "operator-invoked before
tagging, not CI-default", and one is the #157 CRDT undo repro, an
#[ignore]d marker for a known open defect whose arming belongs to that
defect's lane. Seven of the 275 arrive via m10-perf-gates in the
previous commit; this job carries the remaining 268.
ONE JOB, NOT TWO. The shape recorded in docs/active-work.md put the
GPU-requiring suites onto `gpu-render` "which already has lavapipe and
PMACS_REQUIRE_GPU". That job runs `cargo test -p pmacs-gpu` — a
DIFFERENT PACKAGE from the four root-package suites that would move
there, so co-locating them would mean adding a whole new invocation
rather than extending an existing one. Splitting also requires
enumerating which suites are GPU-requiring, and a suite added later
would silently land in the job that needs no GPU and skip there forever.
Running the whole corpus in one place with a working adapter cannot
develop that hole.
PMACS_REQUIRE_GPU is set because these suites do not fail without an
adapter — a37 and its siblings eprintln a skip and return `ok`, measured
at 9/9 in 0.17s versus ~4s for a real run. The build is --workspace
rather than root-only because those suites locate the `pmacs-gpu` binary
beside `pmacs`, and its absence is the documented cause of twelve
gpu_invocation_acceptance failures on a crdt sweep.
The external-tool install block from the `test` job is deliberately not
duplicated. It gates m4_acceptance, m6_5_repl_acceptance and
m6_8_multi_repl_acceptance, and none of those has a single dark test —
measured, not assumed. Installing clangd/zsh/fish/lua/rust-analyzer/
gopls/npm servers again would cost minutes to change nothing. The only
tool-gated code in the dark set is src/process.rs, whose two variables
need no install and are set.
Clippy for the crdt targets runs HERE rather than in the `clippy` job.
Clearing those lints once is not enough: the `clippy` job matrixes over
Lua flavor and never enables `crdt`, so without this step the targets
drift straight back out of compliance and the next job to compile them
is red on arrival — the exact state this lane found. One job now owns
"crdt compiles, lints, and passes."
Verified locally at the exact commands this job runs: clippy green,
doc tests green, and the full serialized sweep with PMACS_REQUIRE_GPU=1
at 3,715 passed / 0 failed / 30 ignored in 366s — identical to the
pre-change sweep, so the lint commit changed no behavior. The 35-minute
ceiling is justified in the job comment against that measurement plus
lavapipe and cold-cache headroom.
This job has NOT yet been proven non-vacuous. That is the next commit:
break a crdt-gated test, confirm this job goes red, revert. A leg added
to a corpus that is already green locally cannot otherwise be
distinguished from a leg that compiles nothing.

`m10_2_perf` and `m10_11_perf` were dark for TWO independent reasons,
and only one of them is this lane's headline subject:
1. They are `crdt`-gated, and nothing in the workflow enabled the
feature, so they were never compiled.
2. Even setting `crdt` aside, no job named them. Grepping ci.yml for
`--test` yielded exactly four suites: acceptance, m4_acceptance,
m5_perf_acceptance, m6_perf_acceptance. Their `#[ignore]` is
deliberate; their absence from every workflow was not.
Fixing both here is a deliberate scope call, taken with the second cause
named rather than absorbed: leaving it would ship a lane headlined "the
dark tests now run" with 7 still dark, and the remedy is one job block,
not a second investigation.
The two suites are NOT the same kind of thing, and the job says so
because a future reader will otherwise assume "perf gates" means
"budgets":
* m10_11_perf asserts one budget — cross-frontend propagation p99
under 50ms. Measured 1.47ms locally, a ~34x margin, so a red here
is a regression rather than runner noise.
* m10_2_perf asserts NOTHING. Six benches that print throughput
numbers, the baselines M10.2's 391x unicode finding and v0.2+
optimization work compare against.
Including a suite that cannot fail a budget needs its own
justification, so the workflow states it: `run_workload` drives 30
seconds of randomized mixed edits against both the v0.1 and CRDT buffer
paths, and nothing else in the corpus exercises a sustained randomized
CRDT workload. Its value here is soak and panic detection, not gating.
The comment explicitly warns against "fixing" it later by adding
throughput assertions, which is how perf jobs become flaky on shared
runners.
Per framing Q#CC3 and §1.3a, `tests/m10_10_perf.rs` is deliberately NOT
touched: it is a CI-default regression tripwire with generous bounds,
not a bench, and adding `#[ignore]` to give it a job would have shipped
a coverage reduction inside a coverage lane. It is recovered by the
plain crdt leg in the next commit instead.
Observed execution, local release build 2026-08-01: m10_2_perf 79s
(6 passed), m10_11_perf 5s (1 passed). The 25-minute ceiling matches
m5-perf-gates and is set by the cold-cache release build, not the ~85s
of tests — the reasoning the file already applies to its other perf
jobs.
Verified: ci.yml parses, 9 jobs, every one carrying timeout-minutes.
Both suites pass locally under the exact commands the job runs.

`cargo clippy --workspace --all-targets --features crdt -- -D warnings`
has never passed on main. The standing gate list runs clippy without
`crdt`, so these lints have never been enforced, and any CI job that
compiles the crdt targets would be red on arrival. This is framing §7
step 1: nothing else in the lane is testable until it lands.
Eight findings across four files, none behavioral:
src/daemon.rs useless_conversion (u64)
src/daemon.rs missing doc backticks
src/daemon.rs too_many_lines (112/100)
tests/auto_indent_crdt_acceptance.rs missing doc backticks
tests/bottom_panel_stage2b_gpu_acceptance too_many_lines (104/100)
tests/vterm_stage3_acceptance.rs too_many_lines (122/100)
tests/vterm_stage3_acceptance.rs too_many_lines (132/100)
tests/vterm_stage3_acceptance.rs redundant `continue`
--keep-going is what made this an inventory rather than a lower bound.
docs/active-work.md recorded seven findings at 74301d1 and correctly
warned they were "a lower bound, not an inventory" because clippy
abandons remaining targets once one fails. With --keep-going the set is
complete, and it differs from the ledger's in both directions: the
`unneeded mut` at src/daemon.rs:4965 is gone (fixed incidentally by
later work), a finding in bottom_panel_stage2b_gpu_acceptance.rs is new,
and every src/daemon.rs line number had moved. A stale lint inventory is
worse than none — it invites fixing lines that no longer exist.
The four too_many_lines findings are silenced with a reason rather than
refactored. Refactoring a test body to satisfy a lint that has never run
would be a behavioral change riding a CI-configuration lane, and the
codebase already has ~20 `#[allow(clippy::too_many_lines)]` sites, the
best of them carrying `reason =`. Each reason states why the scenario is
one test: the GPU acceptances exist specifically to prove a real
daemon, a real PTY and real wgpu fit together, which splitting would
hide.
The redundant `continue` needed care. Replacing it with `Err(_) => {}`
traded the lint for `single_match` — the match then destructured one
pattern. Rewritten as an edition-2024 let-chain, which drops both
without changing semantics: an unreadable message still falls through
to the next loop iteration.
Verified: clippy green with and without `crdt` (the second confirming
no regression to the enforced gate), fmt, diff-check, --lib --features
crdt 2081 passed, and the three touched suites green — vterm_stage3 at
9/9 in 4.34s rather than 0.17s, so a37 really ran rather than reporting
ok on a missing binary.

`.github/workflows/ci.yml` never enables the `crdt` feature anywhere, so
every `#[cfg(feature = "crdt")]` test is not compiled in CI — not
skipped, not filtered, not reported. 279 tests have never executed in
CI, and 186 of them are in the library, whose `cargo test --lib
--features crdt` invocation CLAUDE.md lists as a required pre-PR gate.
CI has never once run a required gate.
Named in docs/active-work.md as "NEEDS A LANE" since it was found while
gating #166, with no branch and no owner until now.
Revision 2, approved. What the scout established beyond the ledger:
- The census moved and was re-measured at 4223dd3: 279 dark, not the
ledger's 273. Plus a fact the old census did not carry — eight test
binaries contain zero tests under CI flags, so they build, run, and
report ok with nothing in them.
- "279 dark" overstates the fix. Eleven are #[ignore]d, so a plain crdt
leg recovers 268. All 279 are now assigned a disposition: 268 by the
leg, 7 by a new m10-perf-gates job, 3 deliberately manual, 1 an
ignored known-defect marker. The lane recovers 275 of 279 and the
other four are excluded for stated reasons rather than left as
residue.
- The classification docs/active-work.md called "the lane's first task"
is finished, and it found three dispositions rather than two:
benches awaiting a job, deliberately-manual operator tests, and
known-defect markers.
- The ledger's clippy inventory was stale in both directions. It warned
its own list was "a lower bound, not an inventory" because clippy
aborts on first failure; --keep-going is what converts it. The
complete set is eight findings across four files, none behavioral.
- A hole in the proposed fix shape: the gpu-render job runs
`cargo test -p pmacs-gpu`, a different package from the four root-package
suites the fix wants to move there. And PMACS_REQUIRE_GPU is absent
from two of those four, so it cannot serve as blanket proof they ran.
- The full serialized crdt sweep is green: 3,715 passed, 0 failed, 30
ignored, reconciling exactly to the 3,746 census. That green result
shaped the acceptance criteria more than a red one would have — a
green pre-measurement is the condition under which a vacuous CI job
ships unnoticed, so the criteria gained a count reconciliation and a
deliberately-broken-test bite.
Revision 1 -> 2 also corrects revision 1's classification of
m10_10_perf, which was wrong in a way that would have made the lane
worse: the suite is a deliberate CI-default regression tripwire with
generous bounds, not a bench, so adding #[ignore] would have shipped a
coverage reduction inside a coverage lane.
Framing only. No workflow change, no source change, no branch plan
executed.

Nine PRs landed since the handoff's anchor (#199-#207) and it named
only four of them, so a fresh machine would not have learned that
ambient-root isolation exists, that the journey arc's 1b split
completed, or that the reap-ledger diagnostic landed. The ledger's
canonical base and recovery floor were five merges stale, and three
lanes described merged work as in flight.
Taken now because ZERO PRs are open. The ledger's own rule is never to
open a standalone refresh PR — because with several PRs open a lane
written on `main` re-conflicts at every merge — and this is the one
window where that cost is nil.
The handoff gains §1a, "Outstanding work — the whole board", which is
the point of the pass rather than a by-product: every arc against §20's
priority order with its next step, every open lane, every deferred item
attributed to the framing that parked it, and the standing hazards
someone running gates on a new machine needs — the three known flakes
by name, the basedpyright skip, the crdt sweep's build prerequisite,
and why a green a37 means nothing alone.
Two arcs completed, so per rule 4 their lanes are removed and their
facts are in the handoff: Journey Stage 1 and test ambient-root
isolation. Discovery and reap-ledger merged a stage each, so their
lanes are rewritten to the remaining plan rather than deleted — the
discovery lane now enumerates Stage 2 in dependency order and carries
the two Stage-1 facts a Stage-2 author would otherwise rediscover.
Base and floor advance together to `cfc1710`, per the file's own rule
that a floor accepting an older commit than the declared base passes on
a tree the document does not describe.
The recovery path was EXERCISED rather than asserted: from an empty
directory, clone, alias, fetch, floor check, and a lane worktree all
ran clean. The two-argument `git worktree add` still fails for a
remote-only branch, which is why every lane spells out the `-b` form.

CI caught this on all four test legs. The forwarder body called
`pmacs.command.invoke_interactive`, which raises when the alias is
reached through `pmacs.command.invoke` — and
`tests/config_registry_acceptance.rs` does exactly that, three times.
The acceptance pin passed throughout because it drives the M-x path,
which is the path the framing spent three review rounds getting right.
Being right about one entry point is not the same as covering the
command, and a rename touches every caller of the old name regardless
of how it is reached.
Plain `invoke` is also the correct semantics rather than merely the
working one: the interactive-command boundary is rotated once, by
whatever entry point the user actually used, for the name they actually
typed. Rotating again on the inner call would record a second boundary
for a command the user never invoked.
Adds `d8c`, which invokes both forwarders programmatically. Bitten by
restoring `invoke_interactive`: the new pin fails alongside the three
config-registry tests that found it.

The isolation lane (#206) landed with an adoption ratchet, and it
caught this branch's brand-new suite on the first run after the merge:
these suites construct an editor through the ambient entry points,
so they read the developer's real init.lua and write into their real
data root: ["discovery_acceptance.rs (1 site(s))"]
That is the ratchet working as designed against code written by someone
who was not looking at the isolation lane while writing it — which is
the case it exists for.
`discovery_acceptance` is therefore MIGRATED, not allowlisted: it
includes `common/iso.rs` and constructs through
`EditorState::new_with_roots(&iso::roots())`. Allowlisting would have
put a fresh ambient site into the census the same day the census was
built.

Review round 2 on #207, two findings, both accepted.
Three places said workers have no discovery surface. They do:
`editor.list-workers` opens `*workers*` via M-x, which §2's own step-11
row has recorded all along — so the document contradicted itself. Two
of the three were mine, including the bullet I wrote last round while
correcting a different stale claim in the same section; grepping for
the phrase found only the two pre-existing sites because my own copy
was split across a line break.
Corrected to say what is actually missing, which is not the same thing
for the two subjects: PACKAGES have no comparable surface at all, while
workers have one and lack §9's ownership model and activity indicator.
Collapsing those into "no discovery surface" would send a reader at the
wrong work.
Separately, §4's extension-surface list called completion/minibuffer
sources "a fixed Rust vocabulary". `parse_completion_source` accepts a
Lua function as `CompletionSource::Custom` — the mechanism this very PR
uses to give `help.describe-setting` completion with no Rust. The claim
now names it, since a reader who believed the old text would conclude a
custom source needs binding work it does not.

§7 said the classification comes first and alone, "its answer belongs in
review before any mechanical edit rides on it." The classification came
back at 342 sites across 66 of 97 files, and the whole-corpus migration
rode this PR anyway. That was a decision, not an oversight, and revision
5 records it as one so a later reader does not have to reconstruct it
from the diff.
The reasoning, in short: splitting would either leave 65 suites still
writing the developer's real data root while the seam sat unused, or ship
acceptance 12's ratchet with a ~65-file allowlist — and a ratchet
exempting most of the corpus records rather than ratchets. §7's ORDERING
is honoured (the census is the first commit); its implied SCOPING is not.
Revision 5 also records what review round 1 established about the shape
acceptance 12 needs: "a narrow, named allowlist" is not sufficient by
itself, because narrowness constrains which files are exempt and says
nothing about how far each exemption stretches. Exemptions carry counts.
`docs/active-work.md` picks up the same two facts and the PR number.

Review round 1: `isolated_construction_is_init_complete` asserted its
paired half — that the *ambient* constructor is unchanged — with an
ambient `EditorState::new()` in an ordinary parent test. That reads the
developer's real `init.lua` and materializes packages into their real
data root: the exposure this suite exists to remove, committed by the
suite itself.
The claim is worth keeping, so it moves rather than dies. It now lives in
the re-exec'd positive control, which runs only as a child under a
hostile-by-construction environment. That is the one place an ambient
constructor is safe, and so it is where every ambient claim this suite
makes belongs.
**The ratchet did not catch this, and that is the more important half.**
`ambient_isolation_acceptance.rs` was on the allowlist for its positive
control, and a bare file-level exemption licenses the named file to grow
new ambient sites forever — which is exactly what happened. So every
exemption now carries its **exact permitted site count**, and a file with
more sites than it was reviewed with fails even while allowlisted. A
count that drops fails too, so the allowlist stays a census rather than
drifting into a ceiling nobody rechecks.
The count immediately earned itself: it rejected the number written from
memory for `journey_acceptance` (47) and reported the real one (26 — 19
`new()` + 7 `open(`, after the scanner drops two assertion-message
mentions and the assembled `concat!` needle).
Verified in both directions: restoring the removed ambient site fails the
ratchet with `2 site(s), allowlist says 1`; and with the ambient half
gone, both init-complete pins still fail under the `if roots.is_ambient()`
mutation, so neither has become a test that passes for the wrong reason.
