1. THE CENTRAL RULE LACKED ITS TIME QUALIFIER. It said any red matching
a retired row is a recurrence — under which this PR's own R2 finding
reopens R2. Now: a match POSTDATING the retirement challenges the
disposition; a match predating it corroborates. That is not a
technicality. An occurrence scan reaches backwards by construction, so
most matches it finds are the earlier kind, and the old wording would
reopen every retired row the first time anyone scanned.
2. R5 AND R6 SAT UNDER "RETIRED ROWS" while declaring themselves live
and undiagnosed. I inserted them before R2's heading, which put them in
the wrong section — presentation contradicting classification in a file
whose whole job is classification. Moved under Live rows.
3. RECOVERY ANCHORS STILL DECLARED 12f2970, so the check accepted a
checkout lacking #216 and #217 while the same file described both as
complete. Advanced to db1bbe9, with the ancestry verified rather than
assumed.
4. THE HANDOFF'S DURABLE TREE FACTS STILL SAID IDS ARE OPAQUE AND
COMPARED BY EQUALITY — the contract ef99b64 deliberately narrowed. A §5
lesson explaining a correction does not fix a summary that still states
the uncorrected fact; the summary is what a new agent reads first.
Corrected there and in the header, which also still called Stage 2 in
flight and anchored main at f186253.
AND ONE FINDING FROM RE-EXERCISING THE RECOVERY PATH RATHER THAN
SWAPPING ITS SHA. This file claimed `git worktree add <path>
githubsucks/<branch>` fails with "fatal: invalid reference". It does
not fail. On git 2.55.0 it SUCCEEDS and leaves a detached HEAD — no
branch, no upstream.
Still use -b, but the reason is the opposite of the one recorded: the
hazard is not an error that stops you, it is that nothing stops you.
Work committed there sits on no branch and is not pushed by a bare
`git push` — the "uncommitted work does not travel" hazard wearing the
shape of committed work. A documented error message that never appears
is worse than no documentation, because the reader waits for a signal
that is not coming.
Verified: fmt, diff-check, --lib, listview 26/26. Recovery path re-run
from an empty directory at the new base; all four steps clean.

The ledger requires a lane for every open PR. #171 drifted 153 commits
while invisible here and #215 had no lane until review caught it, so
the block goes in with the lane's own commits rather than after someone
asks for it.

RULE 4 REMOVES A LANE AFTER MERGE, and two were overdue: the tree
primitive (#217) and macOS CI signal integrity (#215, #216).
The macOS arc could not simply be deleted. It owned R1 and R3, and a
lane removed while it still owns undone work does not close that work,
it hides it. R1 goes to a new async-runtime block; R3 goes to the
reap-ledger lane, which already parks every disposition change pending
exactly its question. Re-homing first is why this did not happen at
merge.
AN OCCURRENCE SCAN (last 25 main runs: 23 green, 2 red) found both reds
unrecorded, and I misattributed both on the first pass — by theme
rather than by required fragment, which is the exact error the registry
exists to prevent.
- Run 30710662474 is NOT R3. Same test, same EPERM, same
measured_group=unobservable(ESRCH...) — but R3 requires `leader=live`
and this reads `leader=exited(signal SIGUSR1)`, R2's exact fragment.
It is a second R2 occurrence, four days BEFORE R2's retirement, so it
corroborates the row rather than falsifying its disposition. It also
adds something: macOS luajit where R2's evidence was lua54, so the
mechanism was never flavor-specific. Filing it as R3 would have
attached a live possible product defect to an occurrence of a fixed
test race.
- Run 30555667095 is NOT R1. Different test, different module,
different assertion; they share only "supersede under a deadline on
macOS". Sharing a subject is not sharing a signature. Filed as R5,
undiagnosed.
R6 is the acc28 readiness timeout from #217's CI. Its scope is the
AUDIT, not the call site: three independently written readiness helpers
now exist and they disagree, with bottom_panel_stage1's carrying only
the zero-byte half of #216's hardening. R4's disposition predicted this
recurrence under a new selector. Patching acc28 alone repeats the
mistake this arc already made once, when the empty-file predicate was
fixed in one helper and left in its neighbour.
The registry carries a rate for the first time — a floor, not a
measurement: main only, 25 runs, readable reds only.
Four durable lessons to the handoff, two from the tree review: an
optional field the shape depends on is not optional, and a contract two
mechanisms must honour is only as strong as the weaker one.
Verified: fmt, diff-check, --lib, listview 26/26. Docs-only.

#216 landed while this branch was open. Both conflicts are in the
ledger and the handoff, and both sides had independently written up the
same shared-CARGO_TARGET_DIR hazard.
THE TWO WRITE-UPS ARE NOT ABOUT THE SAME OCCURRENCE, and merging them
carelessly would have been a real error. Stage 2's is established: seven
failures against a clean baseline, failure text naming its own cause,
pgrep confirmation, and a dedicated-target-dir re-run at 41/41. This
lane's is the one whose signatures were destroyed before being read —
it has no captured text to match against Stage 2's, and it keeps two
non-causal hypotheses. A mechanism established in one occurrence is not
evidence about a different occurrence that was never characterized, so
the merged bullet says so explicitly rather than letting proximity
imply it.
The ledger records #216 merged and stops saying Stage 2 is in flight.
It does NOT retire the arc, though rule 4 now would: R1 belongs to the
async-runtime lane and R3 is an unresolved possible product defect for
the process-signal lane, and neither has a block yet. Re-homing them is
an absorption pass — not something to fold into a feature PR.

It said "Unpushed while held" while githubsucks/tree-primitive-framing
sat at the same tip as HEAD. Held means no PR is open; it does not mean
the work is stranded locally, and the handoff's portability rule cares
about the latter.
The commit list also claimed to be exhaustive and then excluded the
commit that updated it — a list of that shape is wrong the moment it is
written. It is now the substantive arc, with `git log` named as the
place to get the complete one, and the remote ref rather than a pinned
SHA named as the authoritative tip: any edit to this lane advances past
whatever SHA the lane records, including this one.

FOUR REVIEW FINDINGS, and the first two were right about the tests.
1. THE SELECTION ACCEPTANCE WAS VACUOUS. `tr_1` toggles the selected
root, which sits on line 1 before and after collapsing — so it passes
unchanged under the line-based re-seating that id-keyed re-seating was
built to replace. It proves collapse hides descendants; it proves
nothing about selection. `tr_4` adds the case that discriminates: an
`on_refresh` inserts a row ABOVE the selected node, so the node moves,
and the assertion is that selection follows the NODE. Bitten by
restoring `seat_cursor(p, saved)`: `tr_4` fails with left " kid2",
right "sibling", while old `tr_1` passes — which is the finding,
reproduced.
The substantive assertion is deliberately ordered first. It was second
at one point, behind the fixture check that the node moved, and a
regression then reported as "the insert must move the selected node" —
reading like a broken fixture rather than a broken re-seat.
2. FLAT PANELS WERE NOT BEHAVIOUR-IDENTICAL. `bind_local_keymap` binds
TAB on every listview, so a depthless panel that previously fell
through to the global binding — and to Q#P3's read-only intercept —
began answering "listview: no node here". `listview.toggle` now
delegates to `buffer.tab` when no row carries an id, restoring the
prior path exactly; leaf feedback is kept for panels that really are
trees. `tr_3` asserts the absence of both tree messages rather than
merely that the panel still renders.
3 and 4 are documentation. The lane now lists 38e94dc, and no longer
says the PR is held "pending review of the documentation" that the same
commit supplied — it is held pending the decision to open it. §20 said
to BUILD the tree primitive while §14 already carried ◐; it now says
what actually remains, which is adoption: dired's `i` is the next
constraint source, DAP's variables view is why this was worth building
before them.
ONE RED, CLASSIFIED RATHER THAN RERUN AWAY. The crdt lib gate failed
`composition_overhead_under_ten_percent` at 30.7%. It is an incumbent
handoff hazard, and the branch cannot reach it — the diff versus main
touches no src/, no crate, no manifest. Alone it ran 5/5 green at
-0.6% to +0.2%; the next full run was green. Recorded in the handoff as
a MEASUREMENT, not a cause: five isolated greens establish that the
ratio is nowhere near the threshold when alone, not that contention is
what pushed it over. Not a registry row either — that file judges red
CI runs, and this was local.
Verified: fmt, clippy, diff-check, --lib 1896/0, --lib --features crdt
2081/0, listview 22/22, m4 150/0.

Three updates, one of which was a broken cross-reference of my own
making.
THE DAEMON-LEAK ENTRY POINTED AT A LANE THAT DID NOT EXIST. It said the
unclassified failure was "recorded in the tree lane below"; this branch
had no tree lane. A pointer to nothing is worse than no pointer — it
reads as though the record exists and sends the next reader looking. The
tree lane is added, and since it now sits ABOVE that entry the direction
is corrected too, with a second pointer to the framing §6a where the
occurrence is recorded in full.
The lane carries branch, base, framing revision, every commit, the gate
table with both sweeps and their exact reconciliations, the bite
verification for both behavioural claims, the held-PR state and the
recovery command. It also names what is NOT in scope, because the four
unadopted §14 consumers and dired's `i` will otherwise read as omissions
from this stage rather than as later ones.
COHERENCE.md §14: Tree moves ✗ -> ◐, implemented with ONE consumer. Not
✓, and the row says why: the LSP outline is the only adopter, dired's
`i` remains the deferral in its §13, and the other four named consumers
have not adopted. The organising fact goes in the section rather than
only in the framing — folding is LOCAL PROJECTION STATE, NOT A REFRESH
PROTOCOL, which is why a consumer with no `on_refresh` can fold at all.
The §0 scorecard row moves with the body; a grade table disagreeing with
its own section is the defect this document keeps correcting in others.
The framing's status moves from "approved" to implemented-and-gated,
held for PR review, and four durable facts go to the handoff §1: folding
as projection state; identity being consumer-supplied and compared by
equality, with `line:col` chosen because the `::` parent chain collides
on overloads; `has_children` having to read the full row array rather
than the rendered subset, since a collapsed node's children are absent
from it by construction and the bug would look like fold working and
unfold silently not; and that a bite which passes validates the pair
rather than the test.
The daemon leak stays a separate reap-ledger candidate. It is not tree
scope, it predates this work, and folding it in would make a lane
responsible for a leak it did not cause.

ACCEPTANCE 5, and it needed a real test rather than a weakened claim.
`listview_acceptance` says in its own header that the references panel
"needs a live LSP and is validated manually / via the m4 harness", so it
does not exercise `*references*` at all; the m4 hover test asserts
content PRESENCE, not exact output. Neither would notice a flat consumer
silently gaining an indent column — the regression a tree extension can
introduce. So the coverage is written against the real entry points
through the fake language server.
`*references*` is pinned EXACTLY: the row is the location string and
nothing else. `*lsp*` formats its own two-space indentation, so
"starts with a space" is not a violation there; what must hold is that
the primitive reproduces the consumer's text verbatim, matched as a
WHOLE LINE — a substring would still be found inside a further-indented
copy of itself. Volatile parts (pid, elapsed) are deliberately excluded,
the same normalization reasoning the CI registry uses.
THE FIRST BITE PASSED, AND THAT WAS THE FINDING. Injecting
`string.rep(" ", row.depth or 0)` did not fail the test — flat rows
carry no depth, so it added nothing. I had simulated a regression the
flat path is immune to and would have recorded the test as verified.
The regression this criterion actually guards is an UNCONDITIONAL
column, a fold gutter on every row; with that injected the test fails on
"the flat references row renders verbatim". A bite that passes validates
the pair, not the test — and injecting the wrong defect teaches nothing
while feeling like assurance.
A VERIFICATION RECORD, including one unclassified occurrence. The first
local crdt sweep of this branch reported 7 failures and its SIGNATURES
WERE DESTROYED before being read, piped through an aggregation that
emitted only totals. That is the failure the CI registry exists to
prevent, committed one lane after writing it, and it is why the cause
cannot now be established rather than merely being unknown.
It is recorded in this lane's own framing and deliberately NOT as a
registry row: that registry keys on a normalized signature, and an
occurrence with none would be granted a recognisability it cannot
support — the same reasoning that made the unevidenced incumbents audit
notes rather than rows.
Four re-runs are tabulated with what each supports. Two were not
isolated, including one where my own guard printed "aborting" and did
not abort. TWO GENUINELY ISOLATED RUNS ARE BOTH CLEAN, which supports
repeatability under isolation and establishes nothing about the cause.
Two mechanisms are recorded as NON-CAUSAL hypotheses, because both were
present and neither can now be tested: a shared CARGO_TARGET_DIR (whose
reciprocal case another lane observed independently, with `pgrep`
evidence and failing text that named its own cause), and ~40 resident
leaked daemons. Having two plausible mechanisms and no way to
discriminate IS the result; naming either would repeat the reasoning
this project has rejected — concluding something about an occurrence
from something that was not about that occurrence.
Both mechanisms are recorded as standing hazards in the handoff, and the
daemon leak gets its own candidate lane: 42 orphans, oldest four days,
reparented to systemd with deleted sockets, from
`gpu_invocation_acceptance`'s one-command tests, leaking 3-4 per sweep
as measured rather than estimated. It predates this work and belongs to
the reap-ledger family — a process outliving its supervisor with nothing
watching it — but the existing ledger arms only for `spec.group` and so
does not cover it.
Verified: fmt, diff-check, luajit sweep 3453/0 and crdt 3722/0, each
exactly +4 on its baseline.

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.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.

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.

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.

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.

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".

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.

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,
and `pmacs --help` rendered and read.

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.

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.

§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.

Per §25 the audited claim this stage falsifies is updated on the
landing PR. §5's scorecard row and ground truth both said the
registration metadata was best-in-class with almost no way for a user
to reach it; eleven `help.*` commands now reach it.
The row names what is still missing rather than implying the concern is
closed: packages and workers have no discovery surface, `Command` still
has no title/category/aliases/flags, M-x rows are still bare name
strings, the predicate is still never evaluated, settings value
provenance is still absent, and there is still no help prefix key. The
original audit grade is kept inline for reference.
`docs/keybindings.md` gains the family table and records that the
commands are reachable by name and bound to nothing — the help-prefix
decision belongs to a later stage, for the reason #205 recorded.

`docs/active-work.md`: the lane moves from FRAMING OPEN to
IMPLEMENTATION OPEN, with the implementation branch and worktree and a
recovery command that names them. The framing-only worktree is spent —
its doc is on `main` (#201).
`docs/agent-handoff.md` §3: a local full-suite run needs all FIVE
storage variables controlled, not four. `PMACS_STATE_HOME` outranks
`XDG_STATE_HOME`, so naming only the XDG four leaves a
higher-precedence state override live; and a run isolating only
`XDG_CONFIG_HOME` stops the `init.lua` reads while still writing through
the real data root — every local gate run in this repo before today had
that hole. `HOME` is deliberately excluded: it is the fallback the XDG
roots already cover once set, and it separately drives `~`-expansion,
which `find_file_acceptance` pins on purpose.

Correct the M-x prompt census: six of the eleven canonical commands
need a second prompt, including describe-command. Make the apropos
substring negative discriminate against fuzzy matching with a concrete
non-contiguous fixture and a no-substring precondition. Update the help
index mutation to the twelfth canonical command, and carry all three
corrections into the active-work ledger.
No review findings at 1cc9d96; these are the two product choices the
framing deliberately left open.
Q#D2 resolves to `help.*` canonical with two forwarders. The family is
eleven commands under one prefix, so typing `help` at M-x surfaces all
of it — which is the discoverability win this arc exists for.
`editor.describe-command` and `editor.describe-setting` stay registered
as forwarders, so nothing in muscle memory or in
`docs/keybindings.md` breaks. Two forwarders are duplication of exactly
the kind §5 complains about; they are accepted as the bounded price of
not breaking documented names, and they carry a deprecation path. What
is not accepted is the split family revision 3 shipped.
Q#D3 resolves to substring. `fuzzy_score` is subsequence-based and
descriptions are long sentences, so a short query's letters almost
always appear in order — fuzzy would match nearly every command and
destroy the precision that makes apropos worth having. Acceptance 4 now
pins the decision rather than the intent: a subsequence that is not a
substring must find nothing.
Counts and pins follow the decision: the family is eleven throughout,
the `_show_help` counting stub expects eleven (the two renamed commands
are in it precisely because they were the pre-existing direct callers),
and the preservation pin now drives the forwarders through the real M-x
path — dropping them after the rename is the failure a user with muscle
memory would hit first.

Two factual corrections, both accepted and both verified in the code.
The custom completion source does not control display order. Revision 3
justified sorting the pool by claiming `Custom` candidates appear in
return order; `recompute_candidates` hands the pool straight to
`filter_and_sort`, which ranks by fuzzy score descending and breaks
ties lexically, so the source's order never reaches the user.
The sort is kept, for a reason that is actually true: `filter_and_sort`
applies `.take(CANDIDATE_LIMIT)` to the FILTERED iterator before
sorting, so when more settings match than the limit, pool order decides
which survive truncation. Registration order would make that vary with
an unrelated config edit; sorting makes it reproducible.
Read-only would not mitigate the foreign-`*help*` collision either.
Revision 3 implied it would. A buffer the user created and named
`*help*` carries no intercept of ours, so an intercept on the buffers
we create protects nothing — the renderer still matches on the name and
clears theirs. The missing guarantee is ownership identity: a private
table of buffers this module created, so found-by-name is not adoption.
`listview` carries it as `panels` and dired as its handle table; this
mechanism carries neither. Naming the wrong missing guarantee would
send a later fix at the wrong layer, which is why the correction is
worth its own paragraph rather than a word swap.

Two blocking, two major. All four accepted.
The ledger lane still said revision 1 and still carried the two claims
revision 2 refuted. The cause is worth recording: revision 2's ledger
edit was an assert-then-write block whose later assertion failed, so
nothing before it was written either — while the commit message
reported the whole change as done. This is the second time in this
project that shape has silently dropped edits. The lane is rewritten
from scratch and the result verified by re-reading the file rather than
inferred from an exit code.
`names_from` does not exist. Revision 2's completion source called a
helper nobody has written, over `pmacs.config.list()`'s descriptor
tables where `CompletionSource::Custom` consumes a sequence of strings.
Opening the prompt would have raised on an undefined global. The mapper
is now specified, and sorted — `Custom` presents candidates in the
order returned, and registration order is neither stable nor useful.
`*help*` has no read-only intercept. Revision 2 claimed one while
`show_help_text` writes with plain delete/insert, and #205 had already
recorded that this mechanism has not adopted the generated-buffer write
invariant. §3.4 now names the policies that really are shared —
reuse-by-name, wholesale replacement, the `q` binding, and the
foreign-buffer hazard — and notes that the last is precisely what a
read-only intercept would have mitigated and does not.
The naming was underspecified. With no `help.describe-command` in the
table, calling the existing `editor.describe-*` commands
"aliases-by-retention" was wrong on both halves: nothing forwards to
them and there was nothing for them to alias. They are now explicit
exceptions, the resulting split surface is named as a wart, and Q#D2 is
sharpened to the two ways out — forward the two under `help.*`, or keep
the family `editor.*` throughout.

Two blocking, two major. All four accepted and verified in the code
before the doc changed.
Completion does not close the free-text hole, and revision 1 said it
did. `resolve_accepted_value` returns the literal typed text whenever
no candidate is selected, so a non-matching typo still reaches
`on_accept` and the existing error path; separately, a fuzzy near-miss
can silently describe a DIFFERENT setting, which is a new failure mode
revision 1 did not name. Completion is reframed as assistance, the
acceptance pins both outcomes, and closed-set acceptance semantics are
named as Rust work rather than smuggled in as a side effect of adding
a source.
`invoke_interactive` is not the M-x path — the exact error #205
corrected one PR earlier. It rotates the interactive-command boundary
and calls the body; it opens no palette. The acceptance now states the
real path once and drives it: dispatch M-x, type the name, assert the
selected candidate BEFORE RET (accept does `session.take()`), accept,
and — for the five commands that take an argument — drive the second
prompt too. A pin that stops after the first RET has tested the
palette, not the command.
The `_show_help` seam is an output sink, not a migration seam.
`src/help.rs` has semantic renderers for command/key/buffer/mode/hook/
view and none for settings, lists or apropos, and the seam takes
already-flattened text, so a later migration still has to change each
command's subject-specific logic. The claim is narrowed to what is true
— one owner for Lua `*help*` writes — and paired with a per-subject
renderer function so the future Rust work is enumerated rather than
discovered.
Ground truth corrected: the missing-command list was eight and omitted
`list-settings` while §3.1 said nine; the site count said ten where
nine additions make eleven; `pmacs.keymap.lookup` does not return
`description` (it passes `cmd = None`); and the predicate sites cited
were `MenuItem` fields, not `Command.predicate`. The predicate
conclusion survives on the correct evidence — `src/help.rs:76` and one
assertion past `#[cfg(test)]`.

`COHERENCE.md` §20 Priority 4, which §5 grades "substrate without
surface — the sharpest instance of §1.1" and calls the best
payoff-per-effort in the document. Nine describe/list commands over
introspection that already exists, picking up the family root `M-x
help` that #205 landed and documented for exactly this.
The stage adds no Rust. `pmacs.describe.*`, `pmacs.keymap.list()`,
`pmacs.command.list()` and `pmacs.config.list()` already return
everything the commands render, and `parse_completion_source` accepts a
Lua function as a `CompletionSource::Custom` — so `describe-setting`'s
free-text prompt, which today turns a typo into a status-line error
while `describe-command` has had completion all along, closes with no
new Rust either.
The consequential decision is a single rendering seam. `src/help.rs`'s
cross-referenced renderer is orphaned and the reachable Lua
`show_help_text` renders less, so nine new commands calling it directly
would turn a two-site migration into a ten-site one. Everything routes
through `pmacs.editor._show_help`, and an acceptance pin replaces that
seam with a counting stub — funnelling asserted, not merely intended.
Records that `Command.predicate` is stored and exposed but evaluated
nowhere, and deliberately does not start evaluating it: that makes
commands stop being invocable, which needs its own decision about what
"unavailable" means at each call site. A preservation pin registers a
raising predicate and asserts the command still runs, so a later stage
has to change that pin knowingly.
Adds no keybindings at all — the help-prefix question is taken once,
for the whole family, by the stage that can weigh it against the
constraint #205 recorded.

Review round 2 on #205, one finding, accepted. #204 is this PR's base,
so three places still describing it as open were simply false.
- `COHERENCE.md` §2's step-6 row: "(PR open) ends the silence" ->
"(#204) ended the silence", and the "flips only on merge" clause is
replaced by the reason the row is still Partial at all — a server
that starts and then crashes is unsurfaced, which that landing did
not touch.
- `docs/agent-handoff.md`: the 1b-2 bullet says LANDED (#204), with the
same substituted reason.
- `docs/active-work.md`: 1b-2's per-stage block is removed rather than
relabelled, per rule 4 — it has merged and its durable facts are in
the handoff, which is the precondition for removal.
That last one exposed a structural problem the merge had created: 1b-2's
old lane body had come in *underneath* the unified journey header, so
the file carried two journey sections and the first one's text
described the second's predecessor. There is now one arc lane with
1b-3 nested under it as the only open stage.
Also corrects the reap-ledger lane header, which still read
"IMPLEMENTED, PR OPEN" after #202 merged. Same class of staleness,
noticed while editing the same file.

Review round 1 on #205, two findings, both accepted.
The greeting was written straight into the registry without calling
`notify_buffer_edit`. The window's `TextView` had been indexed while
`*scratch*` was empty, and newlines are zero-width to a painter working
from a stale line index — so the first TUI frame collapsed the whole
three-line greeting onto row 0. Every buffer-text assertion passed
because the buffer content was correct; only the rendering was wrong.
The edit is now captured, the registry borrow released, and the core
notified.
The pin that would have caught it paints a real frame and asserts the
second line occupies its own row AND that row 0 does not contain it —
both directions, because a one-direction check passes when everything
collapses upward. Bitten by dropping the notify call: row 1 comes back
empty with row 0 holding the lot, and it is the only pin that fails.
Second: the project docs still described the arc as it was two PRs ago.
`COHERENCE.md` §20 called 1b-2 in flight and the welcome buffer
unstarted; its arc list said 1b-3 remained; and the ledger's journey
lane header still read "1b-2 PR OPEN" while the 1b-3 block carried a
mangled "Framing only; no code" line left by an earlier edit. All now
describe the PR-head state per §25.

The journey suite conflicted additively — step 4 from this lane, step 6
from #204 — and both are kept: 44 pins now cover steps 2, 3, 4, 5, 6
and 9.
Per §25 the audited claims this stage falsifies are updated on the
landing PR rather than deferred: the scorecard's row 18 and §18's
ground truth both read "Missing" / "missing entirely", and a welcome
buffer plus a reachable cheat sheet makes both false. They move to
Partial. §2's step-4 row stays Partial, because `C-h` still deletes a
word and there is no tutorial.
§18's ground truth now records WHY `C-h` stays as it is, so the
help-prefix question reaches the discovery arc as a stated trade rather
than an oversight: non-kitty terminals cannot disambiguate
Ctrl+Backspace from Ctrl+H, so rebinding it would break Ctrl+Backspace
on every legacy terminal.

Two findings, both accepted.
The pinned API was crate-private while the pin was external.
`tests/journey_acceptance.rs` is a separate integration crate and
cannot call a `pub(crate)` function or match a `pub(crate)` enum, so
revision 3's acceptance 1 could not have compiled. `prepare_startup`
and `Startup` are now `pub`, which is consistent rather than expedient:
`run`, `EditorState::new`, `EditorState::open`, `install_state_dirs`
and `restore_desktop_if_armed` are already public, so the startup
sequence is public surface and this was the piece missing from it. The
alternative — keep it private and move the pin into `src/editor.rs`'s
unit tests — was rejected because §19 wants the journey row in the
journey suite.
The isolation that pin needs is now stated rather than left implicit.
`prepare_startup` deliberately calls `install_state_dirs`, which
resolves `PMACS_STATE_HOME` and XDG roots that tests cannot override
(`set_var` is unsafe and forbidden), so the pin inherits the standing
five-variable ambient-root requirement, asserts buffer content only,
and must assert that desktop restore was unarmed — a developer whose
real `init.lua` calls `desktop_mode(true)` would otherwise get a
restored scratch buffer and a silently different result.
The M-x acceptance still left its key assertion as an "or", and half of
it was impossible: `Minibuffer::accept` does `session.take()` and
resolves against the selected candidate, so after RET neither the
session nor the typed contents survive to be asserted. The framing now
specifies one observable, available before RET:
`pmacs.minibuffer.selected()` must equal exactly "help", then accept.
If the completion source selected something else the pin fails there,
naming what was actually selected, instead of passing on a help buffer
some other command produced.

Two acceptance holes and one doc correction, all accepted.
The real startup wiring was still unpinned, and revision 2 knew it: it
named the gap and then accepted it as residual, which is worse than
missing it. Deleting the sole `run()` call to `finalize_local_launch`
would have left every proposed pin green while shipping no welcome —
pin 1 called the seam by hand and pin 10 only proved constructors were
blank. That is the shape of a guard with no production caller passing
every direct-call test.
The fix is extraction, not disclaimer. Everything in `run()` from
`install_panic_hook` through the end of the attach-dispatch match is
terminal-free; `Frontend::new()` is where takeover begins. That prefix
becomes `prepare_startup`, which `run()` delegates to and which the
welcome pin now drives. Deleting the finalize call inside it turns the
pin red. What stays outside a test is `Frontend::new()` and the event
loop, which is where terminal takeover genuinely lives.
Acceptance 4 was not the M-x path. `pmacs.command.invoke` is the
programmatic API; M-x is `editor.execute-command`, which opens a
minibuffer with the `commands` completion source and calls
`invoke_interactive` only on accept. The pin now dispatches the chord,
enters the name, and accepts — and names the hazard that makes that
non-trivial: a selected candidate shadows typed text, so the pin has to
assert which command ran rather than trusting that some help buffer
appeared. dired refused a completion source on its own prompt for
exactly this reason.
Also corrects the #204 references: revision 2's history said it had
landed while the framing footer and ledger still called it open.

Claude-Session: https://claude.ai/code/session_01Lv428Fth9LRtffwJSsqH7T
Four findings, all accepted and verified in the tree first. The three
open questions are answered and folded into the design: three lines,
name `C-c c` and `C-c t` verified from structured entries, and the
command is `help`.
The startup seam was wrong, and every acceptance criterion rested on
it. `EditorState::new()` is not the no-argument entry point:
`EditorState::open` calls it before resolving the target, the daemon
constructs one too, user config runs inside it, and desktop restore
happens much later inside `run()`'s `RunLocal` arm. Greeting from
`new()` would greet a daemon, greet before a file argument replaced the
buffer, and precede anything config or a restored session put in
`*scratch*`. The stage now adds a launch-finalization seam called right
after `restore_desktop_if_armed`, using the `had_file` signal already
threaded to that point. Its untestable part — that `run()` calls it —
is stated rather than papered over, and bracketed by pins proving the
seam works and that no constructor greets on its own.
The step-2 pin amendment is withdrawn. Revision 1 analysed a
status-line welcome and then chose `*scratch*` but kept the amendment,
which was an internal contradiction. The status stays empty so the pin
stays true, and "no error text" has no defined predicate over an
unstructured status string — replacing an exact check with a fuzzy one
would weaken the ratchet to buy nothing.
The claim that this stage carried no §25 obligation was false. The
scorecard's row 18 and §18's ground truth both read Missing, and a
landed welcome plus reachable cheat sheet falsifies both: they move to
Partial on merge while §2's step-4 row stays Partial. A stage can be
too small to flip its journey step and still falsify a "missing
entirely" grade.
Acceptance 2 could not have been implemented as written. Scraping key
sequences out of prose is ambiguous — `M-x help` mixes a chord with a
command name, and `C-c c` is two chords whose boundary the text does
not mark. One structured entry list now both renders the text and
drives the `pmacs.keymap.lookup` checks, and `M-x help` is exercised
through the real palette path.

The last of the 1b split. Journey step 4 and `COHERENCE.md` §18: a
fresh `pmacs` greets the user with an empty buffer, an empty status
line, and no indication that `M-x` exists — the sole discovery
affordance in the product is knowing to press it.
Three findings shape the design:
- The existing step-2 ratchet pin collides with any welcome. It asserts
`status.is_empty()` while its own message says "reports no error" —
the same predicate only while nothing writes a non-error status at
startup. The framing corrects the assertion to its message's claim
and names that as the one existing assertion the stage changes,
rather than burying it in a diff.
- `C-h` is not free. It is bound to word-delete because non-kitty
terminals cannot disambiguate Ctrl+Backspace from Ctrl+H — both
produce byte 0x08 — so rebinding it to a help prefix would break
Ctrl+Backspace on every legacy terminal. §2's step-4 row calls it an
oversight; it is a deliberate trade with a stated rationale. The
help-prefix decision is deferred to the discovery arc with the
constraint recorded so it is inherited rather than rediscovered.
- A `*help*` buffer mechanism already exists over `src/help.rs`, so the
welcome can point at something real. Its two gaps are recorded rather
than inherited silently: it writes with delete/insert instead of
`set_generated_contents`, and it is found by name.
The welcome deliberately does NOT use `set_generated_contents`: that
lifts read-only, discards history and marks the buffer generated, all
wrong for the buffer step 5 requires the user to type into immediately.
Step 4 stays Partial — the row names a welcome, a cheat sheet and
`C-h`, and this closes the first plus a minimal second — so this is the
first 1b stage with no landed-evidence obligation on merge.

Stage 1b-1 landed as #203, so the four places it deliberately left
saying "in flight" are flipped here rather than in a standalone docs
PR: this branch already touches all three files, and a separate PR
would re-conflict on every merge.
- `COHERENCE.md` §2's step-9 row: Partial -> **Works**.
- §2's keybinding-inversion paragraph: all three examples answered. The
quote itself is deliberately unchanged — it names a bias, and three
fixes do not retire a bias.
- §20 Priority 1 and the arc list: 1b-1 landed, 1b-2 in flight, 1b-3
remaining.
- `docs/agent-handoff.md` §1: IMPLEMENTED -> LANDED.
Conflicts were additive on both sides and are resolved keeping both:
the journey suite carries step 9 and step 6 (34 pins), and §24 keeps
both drift entries — the `ProjectKind::Cargo` naming error and §1.2's
wrong frequency note.
The two journey lanes are unified into one arc lane rather than one
being deleted. Rule 4 removes a lane when its ARC is done, and the
journey arc is not: 1b-2 is in flight and 1b-3 is unframed. Stage 1a
and 1b-1 are summarized there with their facts in the handoff, which is
rule 4's precondition satisfied rather than deferred.

Implements `docs/journey-stage1b2-lsp-guidance-framing.md` (approved at
revision 4, after three review rounds). Lua, tests and docs; no Rust
change and no protocol change.
`COHERENCE.md` §1.2's canonical silence: a preconfigured server that is
not installed failed with no status message, no record and no modeline
marker, while tree-sitter highlighting kept working and masked it. Now
the status line names the command, the language and the errno; the
modeline reads `LSP:!` instead of nothing; and `M-x lsp.status` renders
a durable `*lsp*` panel.
Half of this was already built. `status_buffer_text()` and
`last_error()` have existed since M4.8, exposed to Lua and tested, with
no production caller and no buffer to render into — several doc
comments already referred to "the `*lsp*` buffer" as though it existed.
The reporting shape was likewise already adopted twice inside
`lsp.lua`; the canonical case was silent because nobody had converted
it.
Three tables with three lifetimes, because one cannot do the job:
`reported` is never cleared and includes the command, so repointing at
another missing executable reports again; `failures` is cleared by a
successful spawn so the panel goes quiet on recovery; and a
buffer-keyed projection feeds the modeline, because that provider runs
for every window on every paint and deriving an affinity key inside it
would invoke root resolvers during painting.
The memo is on the report, not the failure: the spawn is still
attempted on every file open, so installing the binary mid-session
recovers with nothing to invalidate.
Adds `tests/lsp_spawn_guidance_acceptance.rs` (16 pins) and a step-6
row to the journey ratchet.

Claude-Session: https://claude.ai/code/session_01Lv428Fth9LRtffwJSsqH7T
One blocking lifecycle gap, accepted. The registry's dispatch order was
read before specifying the fix rather than assumed.
`failed_attachments` is keyed by `tostring(buf)` and revision 3 never
said who deletes an entry, so killing a failed buffer leaked its
projection for the session — and that also made revision 3's sweep
bound ("at most the number of open buffers") false, since the table
could exceed the number of buffers that exist.
Nothing existing would have cleaned it incidentally. The LSP resource
reconciliation finds its work through `attachments_under`, which
iterates `attachments`, and a failed buffer has no attachment by
construction — that is the whole reason the projection exists. The gap
needed its own registration.
Revision 4 specifies:
- `pmacs.buffer.on_removed` registered once per projection, never per
failed attempt, since `attach_buffer` is reachable more than once for
the same buffer and per-attempt registration would stack callbacks —
the same unbounded-registrar shape with the leak moved rather than
fixed.
- The handle released on the success sweep, where the buffer is still
alive, but not from inside the removal callback: dispatch does
`callbacks.take(id)` and then iterates a local vector, so the entry is
already gone.
- Rename and delete CLEAR the projection rather than re-keying it.
The projection asserts "this buffer's server failed for affinity K",
and after a rename that is no longer known to hold — the new path may
be in a different project or none. Re-keying would assert a failure at
a location where none was observed, which is the error shape this arc
has been correcting throughout.
- The sweep bound now follows from the cleanup instead of sitting beside
it as an independent claim.
Adds acceptance 14-16 for kill, rename and delete, each asserting the
chosen behaviour rather than merely the absence of the forbidden one.

Two blocking, two cleanups. All four accepted, and both blockers
verified by running Lua rather than by reading it.
Recovery was inconsistent across buffers sharing an affinity. Revision
2 cleared `failures[K]` on a successful spawn but cleared only the
succeeding buffer's projection, so: buffer A fails, buffer B succeeds
for the same key, `M-x lsp.status` reports nothing wrong, and A's
modeline still reads `LSP:!`. Revision 2's claim that the two tables
are "written and cleared at the same moment" was false for exactly the
cross-buffer case, which is the normal case for a project with more
than one file. Each projection now carries its affinity key and a
success sweeps every projection holding it. The new pin asserts on A,
not B — a version checking B passes on the broken implementation.
The markerless key had no Lua representation. `key_uri` is deliberately
nil and `t[nil] = v` raises "table index is nil" — confirmed under both
LuaJIT and Lua 5.4 — so the central markerless criterion was literally
unimplementable as written, and leaving it to implementation would have
produced two ad-hoc encodings for the two tables. The framing now
prescribes one key function used by both, with a `u`/`n` discriminator
that cannot collide with any URI and a NUL separator (Lua strings are
8-bit clean, checked).
Acceptance 10 could not have observed what it claimed: making the
command resolvable changes no state by itself, since `failures` is
cleared by a successful spawn. The pin now reattaches before pressing
`g`, and says why that step is load-bearing.
Also corrects the ledger heading, which still said revision 1.

Review round 1 on #203, two blocking findings, both accepted.
The compile-directory assertions used the suite's lexical `canon()`,
but `pmacs.project.detect` canonicalizes before walking
(`canonicalize_or_passthrough`, `src/project.rs:509-511`), so the
compile cwd is filesystem-canonical. On macOS `/var` is a symlink to
`/private/var` and the two spellings disagree — both macOS legs failed
while Ubuntu, where `/tmp` is not a symlink, stayed green.
Fixed with a `detected_root()` expectation, and pinned by a fixture
that launches through an explicit **symlink** so lexical and canonical
paths disagree on every platform. That matters more than the fix: the
original bite ran only on Linux, where nothing could make the two
differ, so no amount of local mutation testing would have caught this.
The new pin is the only one that goes red when the lexical expectation
is restored.
Second: `COHERENCE.md` §2's step-9 row was flipped to **Works** and the
handoff said Stage 1b-1 was **LANDED**, while this PR is open. §25 is
explicit that grades change only with landed evidence, never
aspirationally. Both now describe the real state — the row stays
Partial and names #203 as the open PR that closes it, §20 and the arc
list say "in flight", and the handoff says IMPLEMENTED with the PR
number.
The flip is not dropped, it is owned: the active-work lane records the
four places to change on merge, because an unowned doc flip is exactly
how this ledger's drift starts.

Two blocking, three major, one minor. All six accepted and verified in
the code before the doc changed.
The affinity key was misstated. `ensure_server` sets `key_uri` only
when the root came from config or a marker walk, so a markerless file
keys on nil and loose files across unrelated directories deliberately
share one server per language. Revision 1's "(root, language)" would
have split what the runtime shares and re-reported one failure once per
directory. The memo now uses the real key and the stage changes no
reuse behaviour.
Dedupe and current-failure state were conflated into one record, and
revision 1 said nothing about recovery. One record cannot do both jobs:
keep it and `*lsp*` shows a failure the user has already fixed; clear
it and the message returns on the next file open. They are now two
records with different lifetimes, the reported identity includes the
command so repointing config at a different missing executable reports
again, and recovery is pinned in both surfaces.
The modeline provider is a pure per-buffer projection by design — it
runs for every window on every paint. Revision 1's "read the failure
table" would have made it derive an affinity key, invoking user root
resolvers and project detection inside painting. The failure is now
projected per buffer at attach time and the segment stays one map
lookup, with a preservation pin that counts resolver invocations.
"Adopt listview's idiom" is replaced by requiring `pmacs.listview.open`
and naming what it guarantees, including `on_refresh` — without which
`listview.refresh` early-returns and `g` is a bound key that silently
does nothing.
The acceptance had no journey ratchet row despite the stage making step
6 real; `tests/journey_acceptance.rs` states that steps 6-12 join as
later stages make them real, and 1b-1 added step 9 the same way. The
end-to-end row is now acceptance 1 and the M4 pins stay beneath it.
Also refreshes the ledger's canonical-base anchor and recovery floor
from `7586905` to `fbcf235`.

`COHERENCE.md` §1.2's canonical silence, and journey step 6: a
preconfigured-but-missing language server fails with no status message,
no record, and no modeline marker, while tree-sitter highlighting keeps
working and masks it.
Three findings shape the design, all verified in the tree:
- The reporting pattern is already adopted twice inside `lsp.lua`
itself — root-resolver failures and subscriber failures both report
through `pmacs.editor.set_status` with the `pmacs.error` arm riding
along. The canonical spawn failure at `:658-674` was simply never
converted, so this stage finishes an adoption rather than starting
one.
- Half the stage is already built and unwired.
`LspManager::status_buffer_text()` renders "the `*lsp*` status
buffer", `last_error(sid)` exists, and both are exposed to Lua and
tested — with no production caller, no `*lsp*` buffer and no command.
Several doc comments already refer to that buffer as though it
exists.
- COHERENCE's frequency note is wrong, and the correction decides the
hardest question. It records the failure as firing once per project
root; `LspManager::spawn` returns early *before* both
`status_tracker.ensure` and `clients.insert`, so a failed spawn
leaves no record, the affinity loop cannot see it, and the real rate
is once per file open. Hence the rule the stage adopts: memoize the
report, not the failure — the spawn is still retried, so installing
the binary mid-session recovers with nothing to invalidate.
Records one limitation rather than hiding it: `status_buffer_text`
renders from `self.clients`, which a failed spawn never enters, so the
durable surface cannot yet show the failure natively. The record stays
in Lua for this stage.
Also logs four stale `COHERENCE.md` §1.2 citations for correction when
the stage lands.

Implements `docs/journey-stage1b1-compile-defaults-framing.md`
(approved at revision 2). Lua, tests and docs; no Rust change and no
protocol change.
`C-c c` now runs `compile.run`, and the first prompt is prefilled from
the detected project kind through `pmacs.compile.defaults` — seeded
`rust = "cargo build"` and extensible from `init.lua`. `_last` still
wins, so a session that has compiled keeps its own command.
The prompt CAPTURES its directory rather than re-resolving it. Sharing
one resolver between the prompt and the run is necessary and not
sufficient: `pmacs.minibuffer.read` is asynchronous and nothing freezes
the active window while a prompt is open, so two calls to the same
resolver at two different moments are still two different answers — the
user could be offered `cargo build` for A and handed a run in B by
clicking away mid-prompt. This is Journey Stage 1a's `commit_to`
discipline on a smaller seam.
`pmacs.compile.defaults` is public and assignable, so the lookup is
guarded: a throwing `__index`, a non-string entry and a non-table
replacement all degrade to the pre-stage empty prompt and never
prevent compiling.
Only `rust` ships seeded. Rust has one answer; npm/yarn/pnpm,
make/cmake, and `go build` versus `go test` do not, and a wrong prefill
costs more than an empty one.
Adds eight step-9 rows to the journey ratchet and five module pins to
the compile suite. Corrects `COHERENCE.md`, which named a
`ProjectKind::Cargo` that does not exist — the variant is `Rust`, line
77 is its doc comment, and Lua only ever sees the tag string "rust".

Review round 1, one finding, accepted.
"A failed escalation is never retried by anything" was false.
`shutdown()`'s force-kill loop iterates the reap ledger with **no**
`!entry.killed` guard, so it does re-kill an entry the escalation arm
gave up on. The accurate claim is that no later *tick* retries it —
`tick_reap_ledger`'s escalation is guarded by `!entry.killed` and never
fires again for that group.
The overclaim collapsed two failure modes that this lane exists to keep
distinct: a failed escalation leaks the group until editor exit, where
one more attempt is made, while a failed `shutdown()` force-kill leaks
it past exit with nothing left to try. Narrowed in the framing, the
handoff, the active-work ledger and the test commentary.
The corrected claim was asserted in three documents and pinned by
nothing, so it gets a pin: a failed escalation marks the entry, the
survivor stays alive across ticks, and `shutdown()` — with no fault
planned, so its force-kill really lands — still reaps it. Bitten by
adding the missing `!entry.killed` guard to that loop: the new pin
fails and the other five stay green.

Not a new design round. Every bet resolved, and one acceptance turned
out to be satisfiable vacuously.
Acceptance 2's in-drain clause said "the live descendant's named late
output absent" without saying how the descendant stays live. It does
not, by default: `poll_one` TERMs the whole group on leader exit. The
first fixture's marker was therefore absent on both paths, and the pin
would have stayed green with the collapse fixed.
Bets 1 and 2 hold — every site took a directed outcome without
restructuring, and every consequence is reachable, so the lane does not
shrink. Bet 3 resolves the shutdown coupling as real and measured. Bet
4 is falsified exactly as its own clause anticipated: `ProcessEvent` is
keyed by `ProcessId` while the ledger is keyed by pgid and is
deliberately independent of managed records, every production consumer
polls per known id, and `take_all_events` has no production consumer at
all. Q#RL3 is answered accordingly and reporting is parked as its own
lane.
Also records the four sites and the two reusable lessons in
`docs/agent-handoff.md` — that a seam for a background loop has to be
directed, and that an absence assertion is only as good as its
fixture's ability to produce the thing.

Two blocking, two major. All four accepted and verified in the code
before the doc changed.
Sharing one cwd resolver between the prompt and the run does not
prevent drift. `pmacs.minibuffer.read` is asynchronous, nothing freezes
the active window while a prompt is open, and `run` re-resolved at
accept time — so the prompt could offer `cargo build` for A and execute
in B. Two calls to the same resolver at two different moments are still
two different answers. The interactive command now captures
`context()` and passes its `cwd` through to `run`. This is Journey
Stage 1a's `commit_to` discipline on a smaller seam: capture at request
time, never re-derive from whatever is ambient when the async work
lands.
No pin crossed the accept boundary. N1-N5 compared values the prompt
and the resolver had already agreed on, so a wrong directory inside
`on_accept` — exactly the defect above — passed every one of them. Two
pins now accept: N3 switches windows between prompt and RET and reads
the directory back two ways, and N4 accepts `cargo build` unedited in a
real Cargo fixture and asserts a clean exit.
N3's old falsifier was not discriminating: `project_root_of_active()`
already returns the innermost root, so re-detecting from it yields the
same kind and the pin would have stayed green. The mixed-fixture pin is
now N5 with a falsifier it actually catches, and says what it does not.
And §6.1 contradicted §3.1 — a Cargo workspace subdirectory holds no
`Cargo.toml` and correctly receives `cargo build`. The predicate is a
detected project, not a file in that one directory.

`COHERENCE.md` §20 Priority 1 names Journey Stage 1b as the golden
journey's remainder and it had no branch, no framing, and no lane —
the only §20 priority with nothing in flight. This frames the first
third of it: journey step 9, build or test the project.
Scope is a global `C-c c` for `compile.run` plus a first prompt
prefilled from the detected project kind instead of empty. Lua, tests
and docs; no Rust change, no protocol change. LSP spawn guidance and
the welcome buffer are separate stages (§7).
Three ground-truth findings the framing rests on:
- `ProjectKind::Cargo` does not exist. COHERENCE names it twice; the
variant is `ProjectKind::Rust` and line 77 is its doc comment. Lua
matches the tag string `pmacs.project.detect` already returns, so
the stage needs no new Rust primitive.
- The compile cwd is resolved inside `run`, after the prompt closes,
so a suggestion built in the command's `fn` would obey a different
rule than the run. The stage extracts one resolution and has both
consume it.
- The last-resort cwd is `std::env::current_dir()` at call time, which
in tests is the pmacs repo root — itself a Cargo project. Negative
pins are built so that fallback is never reached.
Records one limitation rather than fixing it: after `pmacs <dir>` the
active buffer is dired's and pathless, so the cwd falls through to the
process cwd. That needs COHERENCE §8's execution-location model, not a
reach into dired's private handle table.
Adds the journey lane to the active-work ledger.

Refine the framing's in-drain test seam: a one-shot probe error cannot
survive the 50 ms quiescence interval, so the test-only override lasts
for one drain context and remains per-supervisor. Name the in-drain
SIGKILL as a non-observable local fact rather than adding an untestable
seam, and synchronize the revision-three ledger record.
The revision-2 commit shipped the framing alone. Its ledger edit was
generated by a script that aborted on a line-wrap mismatch before
writing, so `b881bd4` left the lane entry describing revision 1 — three
silent failures instead of four, no in-drain twin, no site-directed
seam, and the withdrawn "Bet 1 ships alone" staging.
Synchronized now: four sites including `final_drain_runtime` and its
distinct reader-cancellation consequence; journey step 9 rather than 8;
the `any_running()` precondition on the shutdown coupling; and the
first PR scoped as seam plus tests.
The failure mode is worth naming, because a partial write is exactly the
shape that leaves a document confidently wrong: the commit succeeded and
reported one file changed, which is easy to read as success when two
were intended.
Unparked from PR #200's §5, which retired the premise justifying the
ledger's leniency and deliberately changed no disposition.
Scouting found three silent failures where #200 named two. A probe error
of any errno drops the entry and cancels escalation; a failed escalating
SIGKILL is recorded as a success and never retried; and `shutdown()`
discards its own force-kill result identically — on the path written
specifically to stop a leak at editor exit.
Two facts shape the lane. `shutdown()`'s final loop terminates when the
ledger empties, which happens through the same silent drop, so the probe
error that hides a leak can also end the cleanup loop early — the probe
cannot be made strict in isolation. And all three paths are untestable
today: `tick_reap_ledger` and `shutdown()` call nix directly and consult
no injection seam, unlike `signal()`'s `forced_kill_errno`, so every one
of the five existing ledger tests exercises only the success path.
Diagnosis first; no disposition change is proposed. Stage A of the signal
lane had three tolerance rules rejected across three revisions, each for
concluding something about one entity from something about another, on
this same data structure.
The framing states plainly that none of the three has been observed:
#200 saw an explicit SIGTERM fail in `signal()`, not a ledger call.
Framing only. No code.
`docs/active-work.md` auto-merged without conflict — this branch's lane
entry sits above the folding lane, clear of the six blocks #199 removed.
Verified rather than assumed: all lane headers checked afterwards.
The merge surfaced a stale statement on `main`. The process-signal lane
still read "PR #200 open, four review rounds closed, held for review",
which stopped being true when #200 merged as `a2a92bb`. Its arc is
complete — Stage A #176 and Stage B #200 both landed, and the items its
§5 parked become their own lanes — so under the rule #199 established
(a lane retires when its ARC is done, not when a PR merges) it is
removed and recorded under "Closed since the last snapshot".
Doing that here rather than deferring it: this PR already edits the
file, and leaving a known-false statement on `main` to keep a PR
single-purpose is the wrong trade. The alternative was letting it stand
until the reap-ledger lane, which is scoped next and inherits from the
very §5 list being retired.
Review round 4: three blocking, one major. All accepted.
**`measured_group` was sampled after the failure.** It ran inside
`signal_failure_report`, after the `kill` and after `observe_leader`,
while the framing and the function's own doc both said before. A
concurrent group change would have made the diagnostic report
post-failure state as evidence about the attempted target. It is now
sampled in `signal` before the kill and passed into the report, so the
field describes the target that was attempted rather than the state the
failure left behind.
**The Linux corroboration did not exercise the production lookup.** Its
helper read `portable_pty::process_group_leader` — the accessor this
lane stopped using on the signal path — so `pty_foreground_group` could
have fallen back on every call with every test still green. Forcing it
to always fall back demonstrates the hole exactly: the corroboration
fails, and the injected pin PASSES, because the injected tests supply
the group themselves and structurally cannot detect a broken lookup.
The helper now calls the production lookup, and the corroboration forces
only the kill so the report is built from a real terminal read. The
residual limitation is recorded rather than left to the green: on macOS
`pty_foreground_group` has no end-to-end coverage, because the platform
cannot produce the precondition.
**The framing did not update its own acceptance contract.** Revision 5
recorded Bet 1's falsification in the revision history and in the bet,
and left the normative criterion demanding the real-shell rewrite — the
"implementation quietly diverges from the contract" shape this project
already recorded as a lesson on #191/#188. Acceptance 1 now describes
the injected pin, 1a adds the corroboration and its macOS limitation,
and 4 states the sampling order. The ledger is synchronized: revision 6,
four commits, 4,471 tests, bash armed on Linux only.
**`TargetSource`'s doc had the wrong classification.** Two of the four
variants target the leader pid, not one, and the pid-versus-group split
does not line up with PTY-versus-pipe — which is why the fallback needed
its own variant rather than reusing `LeaderPid`.
Gates: 11 gates, 4,471 tests, zero failures.
One blocking and two major findings, all accepted.
- The isolated gate still inherited `PMACS_STATE_HOME`, which wins over
`XDG_STATE_HOME` in `user_state_dir` (`src/state.rs:47-68`), so
controlling the four XDG storage variables did not isolate state on a
machine that exports it. The contract now names the exact five
variables rather than counting roots.
- Q#TI5 still called self-spawn the durable regression guard after
revision 3 had accepted that it proves behaviour, not continued
adoption. It now names both guards and their different jobs: self-spawn
is the behavioural proof, the checked source inventory is the adoption
proof.
- The active-work lane still said revision 2 and still prescribed an
isolated `XDG_CONFIG_HOME` alone; both are synchronized, and the stale
config-only gating note elsewhere in the ledger is corrected to say it
isolates the observed symptom rather than the gate.
Framing only. No code.
`docs/active-work.md`'s snapshot header was the only conflict; main's
absorption version supersedes this branch's. `docs/agent-handoff.md`
auto-merged, and both sides were verified present afterwards rather than
assumed: the absorption's `4cd4a7b` anchor and its new landed-lane
entries, and this branch's macOS occurrence with its run link.
This lane's ledger entry is updated from "revision 4 awaiting review" to
its actual state — implemented, gated, PR open — since the framing was
approved and both implementation commits have landed on the branch.
The full gate suite is re-run on the merged tree rather than inherited
from the pre-merge head. The absorption is docs-only, so a clean merge
is very likely correct — which is exactly when inheriting a green would
be most tempting and least justified.
Three blocking and two major findings, all accepted. Two were verified
by running the thing rather than reading it.
- **Journey isolation had no executable mechanism.** Cargo launches each
integration-test binary with the caller's environment, and a binary
cannot re-point its own roots before its tests run — the `set_var`
prohibition applies to itself. Revision 2's "isolated by its launched
environment" therefore assumed the external wrapper this lane exists
to delete. Now named and pinned: each journey test re-execs
`current_exe()` with `--exact`, a marker, and controlled roots; the
child runs the real body against the ambient `EditorState::open`, so
the production-entry-point ratchet is untouched while the roots are
contained. The same helper serves the hostile-environment check.
- **One self-spawning test is not a ratchet.** It proves the seam works
and cannot notice a raw `EditorState::new()` added to another binary
later. A checked source inventory, falsifiable by adding an ambient
constructor, is now acceptance 12.
- **The root list and the gates disagreed with the audit.** The scope is
now explicit — bootstrap STORAGE roots only (config, data, state,
cache). `HOME`'s non-storage semantics are excluded by decision, not
omission: `expand_tilde` resolves user-entered `~` and
`find_file_acceptance` pins it deliberately, so redirecting `HOME`
would retarget a user-facing feature. `XDG_RUNTIME_DIR` addresses
sockets, not stored data.
- **The gate instruction itself was insufficient**, and this is the
finding with immediate consequences: isolating only `XDG_CONFIG_HOME`
stops the reads and leaves the write path open. Every local gate run
in this repository today had that hole.
- **The count was one high and the ledger overstated it further.** 65
files call the constructor; 66 mention it. The 66th, `m5_6_acceptance`,
mentions it only to say it deliberately does not use it — making it
the third place in the suite documenting the `cfg(test)` gap. The
ledger's "all 96 test files load the real config" was false.
- **The recovery command did not work**, verified by running it:
`git worktree add <path> <remote-only-branch>` fails with `fatal:
invalid reference` after a bare fetch. Replaced with the explicit
tracking-branch form.
Framing only. No code.
Four blocking and two major findings, all accepted, all verified in the
code before acceptance. The lane's scope changes: it is about ambient
roots, not about init.lua.
- The read-only assumption was already false. `EditorState::new`
materializes bundled packages unconditionally and before config
loading, into `XDG_DATA_HOME` or `$HOME/.local/share`, and
`materialize_all` creates directories. Confirmed on the development
machine: `~/.local/share/pmacs/builtin-packages/` exists with v0.1.0
and v1.0.0. This upgrades the lane from "local gates lie" to "tests
write into real user data".
- The population count was wrong and its stated method did not match the
command that produced it: 18 from a grep for `Editor::new`, which does
not match the real constructor `EditorState::new`. 66 of 96 files
construct an editor directly.
- File-level classification cannot work: 5 files are both in-process and
spawned. Classification moves to construction sites.
- The seam must cover `EditorState::open`, which calls `Self::new()`
directly, while `journey_acceptance` requires that exact public entry
point to avoid a dead-production-path test. Resolved by isolating
journey through its launched environment rather than a different call.
- Isolated construction must still return `is_init_complete() == true`.
Config loading and `set_init_complete()` share one block, and
`m8_2_acceptance.rs:75` documents its dependence on integration-test
construction being init-complete — the `cfg(test)` gap is load-bearing
in that one respect.
- Revision 1 both proposed and parked a hostile-config CI leg. Resolved
in favour of a test-binary self-spawn, which travels with the test
rather than the workflow file, and which now also asserts the hostile
root is unmodified afterwards.
- The lane is recorded in `docs/active-work.md`, which revision 1 omitted
despite the volatile-work protocol requiring it.
Also documents six ambient roots where the shared daemon harness sets
two, and why setting HOME only isolates a root whose XDG variable is
unset — the harness's apparent adequacy is a property of one developer's
environment.
Framing only. No code.
Eight PRs merged on 2026-07-29/30 (#188, #190, #191, #194, #195, #196,
#197, #198) and `docs/active-work.md` had drifted to 1,854 lines, most of
it describing work already on `main`. Rule 4 permits removal once a
lane's facts reach `docs/agent-handoff.md`; this does both halves in one
commit so the precondition is satisfied rather than deferred.
Handoff §1: the head-of-`main` anchor moves from `6c9e765` to `4cd4a7b`
and its date from 2026-07-28 to 2026-07-30. New entries for the three
implementation PRs that had no record — #190's pre-filesystem delete
refusal, #191's Stage 1 adoption of the generated-buffer contract, and
#196's dired Stage 2a — plus #188 recorded as landed rather than
proposed.
Ledger: six merged lanes removed (781 lines). Two lanes are NOT removed
and are rewritten to their remaining plan instead, because their arcs are
unfinished: generated-buffer immutability (Stage 1 merged, Stage 2 not
started) and bottom-panel (Stage 2 complete, Stage 3 ahead). The
bottom-panel block said so in its own text — "this lane is not removed at
2B-3's merge" — so a removal keyed on "the PR merged" would have
discarded live planning. The header now states the rule as ARC-done
rather than PR-merged.
Two method notes are recorded in the ledger because they nearly cost
real work:
- A census by PR number is a proxy, not a measurement. Counting `#NNN`
in the handoff reported that five of these lanes had no record at all.
Counting by content found most already documented, with the real gap
being the implementation PRs while their framings were recorded. The
absorption written from the first count would have duplicated existing
entries.
- #194 and #195 keep their lessons in §3 and §5 rather than §1, which is
why a number search finds them once each. Sufficient under rule 3:
durable knowledge needs a home, not a required section.
Docs only. No code, no protocol change.
Integrate canonical main, restore PTY errno capture through the safe
filedescriptor duplication bridge, narrow the macOS occurrence to what
it actually measured, and make the job-control fixture foreground and
discriminating.
Record the portable framing lane and exact recovery commands in the
active-work ledger.
`docs/active-work.md` was the only conflicting file, in the same shape
as #191's: `main` inserted the generated-buffer Stage 1 lane immediately
above the bottom-panel header this branch had rewritten. The resolution
keeps both.
Each side's newer text wins where that side owns the fact: `main` carries
the corrected #188 status (MERGED/APPROVED, replacing "OPEN, PROPOSED —
do not implement"), and this branch carries the bottom-panel lane's 2B-3
state and the newer snapshot date, replacing main's "2B-2 MERGED; 2B-3 IS
NEXT" and its 2B-2 boundary paragraphs.
Verified: no conflict markers; every line absent from either parent is a
deliberate supersession by the other, enumerated and checked one by one
rather than counted; all three lane headers present exactly once.
`docs/active-work.md` was the only conflicting file. #196 added the dired
Stage 2a lane at the position this branch had used to relabel the #188
framing lane header; the resolution keeps both, changing neither side's
wording.
`src/editor_core.rs` auto-merged. Both lanes touch it, so a clean
textual merge is not evidence of a clean semantic one — the gate suite
is re-run in full on the merged tree rather than inherited from the
pre-merge head.
Resolution verified for line loss in both directions: the resolved file
differs from `main` only by this branch's own authored edits, and
differs from this branch only by additions taken from `main`.
Review round 2, three findings.
setsid is util-linux, not coreutils, and the standard `cargo test --lib`
gate must not hard-fail on a tool the README does not declare -- a
minimal or BusyBox container would fail without ever testing pmacs. The
hard assert becomes skip-unless-armed via PMACS_REQUIRE_SETSID, which is
the pattern the silent-skip lane already established, so the test cannot
quietly report `ok` having never run where the tool is guaranteed. CI
arms it on Linux; README declares it. Both arms verified against a PATH
with setsid genuinely removed: unarmed skips with its message, armed
FAILS with the diagnostic.
The durable causal account was wrong, and this corrects it in the
framing, the handoff and the ledger. basedpyright's console script runs
bundled node through `subprocess.run` and WAITS
(nodejs_wheel/executable.py:50, verified in the installed 1.39.6). It
does not exit at spawn. What orphans node is pmacs: `shutdown()` SIGTERMs
the recorded pid -- the Python wrapper -- which dies without forwarding
the signal, leaving node at PPid 1 holding the pipes. The refutation was
already in hand: the initialize handshake succeeds, which a wrapper that
exited at spawn could not have done, and the PPid 1 observation was taken
after shutdown had killed it.
The fix is unaffected -- the deadlock and its bite are unchanged -- but
the parked follow-up changes target: not "tolerate servers that
self-orphan" but "stop orphaning them", i.e. signal the process group
rather than a wrapper pid that swallows the signal. Framing section 5 P2
restated.
Also corrects a stale CI-ordering claim: the handoff said pyright must
stay unarmed until the timeout lane lands, but #195 is this PR's base and
gave every job a timeout-minutes. The one live reason is that CI does not
install basedpyright at all. The ci.yml comment asserting the job has no
timeout-minutes was stale for the same reason and is rewritten.

The four findings were one shape — a failure that left state wrong and
told nobody — so the lane records them as one lesson rather than four
bugs: every one was a `pcall` or a discarded return value, and each
looked like defensive coding.
Also records the round-1 pin that passed with its own bug restored
(acceptance 53's attribution assertion was satisfied by the deleted
path's basename appearing elsewhere in the same message), the refreshed
gate numbers, and that `main` was re-measured after the round and had
not moved.

Handoff section 1 gains the 2B-3 bullet and the protocol anchor moves to
v21 with the rule that matters stated once: advertise the baseline,
negotiate up from the frontend's AttachRequest, and reserve moving the
advertised version for a change that cannot be expressed additively at
all. 2B-1's forward-looking constraint is marked discharged rather than
deleted, because its acceptance still passes unchanged and that is the
evidence.
COHERENCE section 14 grades the bottom/side panel primitive as complete on
BOTH frontends rather than 'Stage 2 pending its own framing', section 20
P5 follows it, and the section-19 protocol bullet records that the v21
family is live in production without an incompatible handshake change.
The active-work lane is rewritten to the shipped slice, including the
rejected activation alternatives and why the server-first shape forces
each one out, and the one-way compatibility window it leaves open.
The 2B-2 acceptance suite's header said production keeps panel_capable
false for every semantic session. That is no longer true, and its
assertions did not change — which is the point, so the header now says so
rather than being quietly left stale.

Rides this branch rather than a standalone ledger PR: with several PRs
open, a lane written on `main` for work that lands elsewhere
re-conflicts on every merge.
Records the measured merge-base as pasted output, what 2b and 2c still
owe so the split boundary is auditable, the two re-pinned m4 rows, the
one framing claim found wrong, the two bites that were vacuous as
specified and why, the gate numbers, and the §16 ownership warning
against starting Journey Stage 1b while this is open.

One conflict, `docs/active-work.md`, with three strands rather than the
usual one: main gained #190's lane, this branch carries its own Stage 1
lane and a relabel of the #188 framing lane, and main had removed the
documentation lane while this branch still had it.
Resolved by construction. Main's file taken whole; this branch's Stage
1 lane reinserted at its own position ahead of the bottom-panel lane;
this branch's relabelled framing lane ("MERGED AS PR #188") kept in
place of main's stale "OPEN, PROPOSED" version; main's removal of the
documentation lane preserved.
Verified against both parents rather than by inspection: the Stage 1
block is byte-identical to this branch's, the documentation lane is
gone, no conflict markers survive, and the update-protocol rule 6 seam
check finds no double blanks.
Note for whoever absorbs next: main now carries three lanes describing
merged PRs (#190, #188, #194). This merge keeps this branch's more
accurate labelling of the #188 one but does not remove any of them ---
rule 4 permits removal only once durable facts reach
`docs/agent-handoff.md`, and none of those three PRs touched it.
Pure insertion: main's ledger taken whole with this lane's 3a block
placed before the parked lane. Verified against both parents --- zero
lines removed relative to main, the lane-3a block byte-identical to
this branch's, no conflict markers, and the update-protocol rule 6 seam
check clean.
Deliberately NOT absorbed here, because absorption is not mechanical
and this PR is approved on its current content. `main` now carries
THREE lanes describing merged PRs: the resource-op delete guard
(#190), the generated-buffer immutability framing (#188), and this
arc's own silent-skip arming (#194). Rule 4 forbids relabelling any of
them and permits removal only once their durable facts reach
`docs/agent-handoff.md` --- and none of the three PRs touched that
file, so all three absorptions are genuinely owed rather than
overlooked.
Two belong to other arcs. The third (#194) belongs to this one, and
its durable fact is not yet written down anywhere: that
`PMACS_REQUIRE_*` arms an otherwise-vacuous skip, and that
basedpyright stays unarmed until the reader-join hang and the CI
timeouts both land. That wants a handoff bullet, which is content
rather than a merge resolution.
P3 --- required status checks are name-coupled to job names, and a
required context that no longer exists does NOT fail. It leaves every
PR pinned on "Expected --- waiting for status" forever, which is `main`
becoming unmergeable by policy rather than by a red run. Three of this
lane's own deferrals will do exactly that: the macOS matrix trim
removes two contexts outright, and nextest or the serial/parallel split
rename or add jobs.
The rule is now in the ledger entry --- any job rename, removal, or
matrix change updates the branch-protection required-checks list in the
same motion --- and it is recorded HERE deliberately, because this is
the single entry that both enabled protection and named the lanes that
will invalidate it. Arming the warning anywhere else would separate the
trap from the thing that sets it.
P4 --- the rewritten top comment said "everything else keeps 25 against
a sub-4-minute observed max" and dropped the clause noting that
`m6-perf-gates` keeps its own tighter 15. Restored. Worth the fixup in
a change whose entire subject was comments matching reality.
Beyond the PR, and taken here rather than deferred: `TEST_IMPROVEMENT.md`
on `main` still said "no branch protection on `main` (verified via API:
404, so every job is advisory)" and listed §5.1 as open. Both went
stale during this session, and THIS lane is what made them stale, so it
carries the correction rather than leaving it for whoever touches the
file next. Struck through in both places rather than rewritten: the 404
was a true reading at audit time, and the document is the arc's scoping
record, so what changed is more useful than a clean-looking present
tense. Note also that protection shipped wider than §5.1 proposed ---
all 12 contexts required, not the cheap-jobs-only starter --- which the
correction states.
Verified: YAML parses; the seam check from update-protocol rule 6 finds
no double blanks; `git diff --check` clean.
P1 --- the ceiling was justified against the wrong number. Revision 1
cited "~14.6 min, ample headroom", which was one reading quoted as a
property, and this ledger's own rule applies to it: a census is a
reading, not a constant. Re-measured over two windows --- 17 min max
over 25 runs, 15.8 over 12, both macOS/luajit, every other job under
4 --- so a flat 25 was about 1.5x the observed tail, not "ample".
Two facts shape the fix. `timeout-minutes` counts EXECUTION, not queue,
so the 33-minute wall-clock run in that window executed its longest job
in 17 and no run in observed history would have been killed by either
value. And the real exposure is the case no window contains: a cold
cache. A stable-toolchain bump invalidates Swatinem's key on every leg
at once, and a cold macOS debug build plus suite is the plausible way a
HEALTHY run overruns --- presenting as four legs timing out
simultaneously the day after a Rust release.
So the test job takes 35 (~2x its observed max) and the rest keep 25
(~6x theirs), and the diagnosis is written into the workflow BEFORE the
event: simultaneous four-leg timeouts after a toolchain release are a
cold cache, not a hang; a single leg timing out beside passing siblings
is the hang case these ceilings exist to catch. 35 still beats the
360-minute default by an order of magnitude, so the basedpyright
arming this gate unblocks is unaffected.
P2 --- §5.1 was missing from both lists, and review was right that the
omission matters. But its premise had gone stale, which is worth
recording rather than quietly working around: branch protection is ON.
It was enabled earlier in this session, and I re-verified against the
API rather than trusting either the review or my own memory of doing
it:
{"enforce_admins":false,"force_push":false,
"required_checks":12,"strict":false}
Recorded in the ledger as DONE with the settings and the reasoning for
each --- `strict` off so a PR need not rebase every time `main` moves,
`enforce_admins` off so the user keeps an override. This also settles
the concurrency comment, which justifies exempting `main` pushes by
appeal to "the branch-protection record": that record exists, so the
justification is real rather than aspirational, and no softening is
needed.
P3 --- the double blank line before the parked lane, third PR running.
Fixed, and added to the ledger's own update protocol as step 6, since
fixing the instance three times has not stopped it: a block ending in a
blank line inserted above a heading already preceded by one leaves the
seam, and it survives review by sitting beneath the level anyone reads
at. The rule now names the check.
Verified: YAML parses; ceilings are 25 except test at 35 and
m6-perf-gates at its tighter 15; the seam check finds no double blanks
anywhere in the ledger; `git diff --check` clean. Workflow and ledger
only.
Keep both active-work lanes while taking the silent-skip arming and
generated-buffer framing changes from current main. The resource-op lane
retains its round-2 fixes and updates its recorded merge-base.
Record the path-normalization and partial-first-operation fixes, their
acceptance criteria and bite pre-images, and the green round-2 gate
results in the active-work ledger.
Lane 3a of the testing arc --- the three cheap, deterministic items of
`TEST_IMPROVEMENT.md` §5-6. The larger ones (nextest, the
serial/parallel split, a parallel canary leg, the nightly cron, the
macOS matrix trim) are deliberately NOT here: each changes what CI
certifies or how it runs, and each deserves its own decision rather
than riding in on a timeout patch.
`timeout-minutes` on every job (§5.2). Measured before changing rather
than assumed: SEVEN of eight jobs had none and inherited GitHub's
360-minute default; only `m6-perf-gates` had one, at 15. So a single
hung test burnt six hours --- times four on the test matrix --- and
reported nothing useful at the end of it. Set to 25 against a measured
~14.6 min critical path (macOS/luajit), which leaves ample headroom for
a slow runner while catching a hang in under half an hour.
This is the gate that has to exist before `PMACS_REQUIRE_PYRIGHT` can
ever be set. Lane 2 left basedpyright unarmed *because* this did not
exist; the two decisions are the same decision, half a lane apart.
`concurrency` with `cancel-in-progress` (§6.1), scoped to pull
requests. This project rebases heavily --- the ledger re-conflicts on
nearly every merge --- so branches take several pushes while earlier
runs are still going, and macOS minutes are both the expensive ones and
the critical path. Pushes to `main` are deliberately exempt:
`github.event.pull_request.number` is empty there, so the fallback keys
those runs by SHA and none can cancel another. Cancelling a `main` run
would leave the branch-protection record ambiguous about a commit that
has already landed, which is the one place the saving is not worth
having.
`-p pmacs-protocol` clippy (§5.7). The root-package clippy never
covered it --- the workspace default member is only `pmacs` --- so a
warning introduced through a protocol-only change would reach `main`
unseen. Verified passing locally BEFORE proposing it, so it cannot turn
CI red on arrival.
The timeout rationale is stated once above the job list rather than
copied onto each job: the first draft duplicated a seven-line comment
across seven jobs, which is the same degraded-copy shape this arc keeps
removing elsewhere.
Verified: YAML parses; all eight jobs carry a timeout (seven at 25,
m6-perf-gates keeping its tighter 15); `cargo fmt --all --check`,
`clippy -p pmacs-protocol` and `clippy -p pmacs-gpu` all exit 0;
`git diff --check` clean. The diff touches `ci.yml` and the ledger and
nothing else, so no code gate is affected.
One conflict, in `docs/active-work.md`, with an extra strand: main
gained #188's lane while this branch had removed the documentation
lane, so the two sides disagreed about a region neither had edited
against the other.
Resolved by construction rather than by editing markers --- main's file
taken whole, the documentation lane removed, this lane's block
inserted before the parked lane. Verified against both parents: exactly
26 lines removed relative to main, which is the documentation lane and
nothing else, and the lane-2 block byte-identical to this branch's.
Records, without fixing, that #188's own lane now reads "OPEN,
PROPOSED" on a merged PR. Rule 4 forbids relabelling and allows removal
only once the facts reach `docs/agent-handoff.md`, which #188 did not
touch. That absorption belongs to the immutability arc's next PR, not
to a testing lane reaching across into it.
Bring the approved generated-buffer immutability framing onto the Stage
1 branch and update both active-work lanes to the landed #188 state.
Main @ 27b1185 changes documentation only relative to the prior base.
Record the revision-7 selection and acceptance reconciliation, the
exact code checkpoint, the non-vacuous fan-out bite, and the final gate
results. Keep PR 188's proposed status and merge ordering explicit.
P1 --- the workflow contradicted this lane's own claim. `components:
rust-analyzer` rode the shared `dtolnay/rust-toolchain` step, which
matrixes over ubuntu AND macos, so the binary would have been present
on both. PRESENCE, not PMACS_REQUIRE_LSP, is what decides whether a
gated test body runs --- the unset variables on macOS only meant
absence would be tolerated there, not that the tests stay skipped. Two
rust-analyzer tests would therefore have executed on macOS for the
first time ever, on the legs that are simultaneously the CI critical
path and the documented flake surface, one of them doing real indexing,
none of it covered by the Linux-only local runs behind this lane. Moved
into the Linux-gated step so the text and the workflow agree.
P2 --- the ledger promised a base and pasted nothing. Worse than the
review knew: a script was run to substitute it, reported success,
matched no text, and the result was never re-read. The claim shipped on
the strength of a tool's exit status. The entry now carries the pasted
base and a recovery command, and records the lesson in the terms this
ledger keeps relearning --- asserting a measurement is not making one,
and a tool reporting success is not the measurement either.
P3 --- tool versions pinned (gopls v0.16.2,
vscode-langservers-extracted 4.10.0, yaml-language-server 1.15.0), so
CI no longer drifts with upstream publishes and a break has a commit
here to bisect against. `tests/support/` now states why it exists
beside `tests/common/`: the latter re-exports daemon and PTY
machinery, and pulling that into three binaries that spawn neither to
reach a six-line environment check is the wrong trade. Recorded as a
cost, with the rule that a third such directory means consolidating
rather than continuing.
Also recorded, because §1.2 is NOT fully closed by this lane: the
guards arm the ENTRY skip only, and m4_acceptance's mid-test
"workspace likely still indexing; skipping" survives --- so even armed,
that test's one assertion can still vanish under load, which is exactly
when a regression would show. Mid-test skips want their own pass. And
the follow-up this lane creates: removing the documentation lane
removes the only pointer to githubsucks/handoff-2026-07-20, so that
branch needs deleting after merge or nothing will ever mention it
again.
P4 --- the consolidated lua skip message names PMACS_TEST_LUAJIT again;
the `or_else(locate_shell("luajit"))` path still honours it and the
escape hatch had become undiscoverable. Double blank line before the
parked lane collapsed.
One gate note worth carrying rather than burying. A `PMACS_REQUIRE_GPU=1
cargo test -p pmacs-gpu` run failed once during this round, naming the
`--bin pmacs-gpu` target, and my gate chain still printed a clean
summary because `cmd | tail -2` in an `&&` chain returns TAIL's exit
status, not cargo's. Four subsequent runs pass 202/202 and the failure
has not reproduced, so it is recorded as observed-and-unreproduced
rather than explained. The masking is the durable part: a gate summary
assembled through a pipe can report success over a failure.
Gates re-run after the fix: fmt; clippy -D warnings; --lib 1863; --lib
--features crdt 2048; m4_acceptance 121; m6_5 11; m6_8 8; required GPU
202 (x4); git diff --check clean.
Absorb #193 without rewriting the reviewed revision 6 or revision 7
commits. Resolve docs/active-work.md by retaining PR #188's proposed
lane and accepting main's removal of the landed bite lane.
Record that the intervening base change touches no product source, so
revision 7's source readings remain current.
Lane 2 of the testing arc (`TEST_IMPROVEMENT.md` §1.2, §5.4).
The shape being fixed reports GREEN when the tool is missing:
let Ok(_) = which_binary("gopls") else {
eprintln!("gopls not on PATH; skipping");
return;
};
CI installed none of these tools, so a block of real-language-server
and multi-shell tests had never once executed their bodies while
reporting success on every run. A suite that cannot distinguish
"passed" from "never ran" is worse than a missing suite, because it
reads as coverage in exactly the place someone would go looking for it.
The fix is this project's own pattern rather than a new one:
PMACS_REQUIRE_GPU already turns a missing adapter into a hard failure
for the headless render job. This adds PMACS_REQUIRE_LSP,
PMACS_REQUIRE_SHELLS and PMACS_REQUIRE_LUA, and the CI step that
installs the tools they promise. Per-tool variables rather than one
blanket flag, so a tool that must stay unarmed keeps that decision
visible at the call site instead of buried in a workflow file.
basedpyright is deliberately NOT installed and NOT armed. Its test has
no timeout and hangs forever; the root cause is the non-interruptible
reader-thread join in `RuntimeHandles::drop`, already a named deferral
in `src/process.rs`, and the `test` job has no `timeout-minutes`.
Arming it today would trade a vacuous green for a six-hour hang across
four legs. PMACS_REQUIRE_PYRIGHT exists and is never set, so the flip
is one line after the hang fix and the CI timeouts land.
A trap found while writing the workflow rather than after: the natural
Actions idiom
PMACS_REQUIRE_LSP: ${{ runner.os == 'Linux' && '1' || '' }}
sets the variable to the EMPTY STRING on every other platform, and
`var_os(..).is_some()` is true for `Some("")`. That would have armed
the guard on precisely the runners with none of the tools installed
and failed every one of them. The helper treats empty as unset, which
makes the common spelling safe instead of subtly wrong.
The helper is SHARED via `#[path = "support/mod.rs"]` rather than
copied into three test binaries. `m6_8_multi_repl_acceptance.rs`
carried a comment saying cross-test-binary sharing "would need a
fixture crate"; it does not, and a correct helper in one file beside a
degraded copy in another is this suite's most repeated defect.
Verified by execution in all three states, using a tool genuinely
absent from this machine (vscode-json-language-server): unset skips
green; armed fails hard, naming the CI step that should have installed
it; empty string skips green. On `main` the armed state cannot fail at
all, because no guard exists.
And the question none of this could answer until now --- whether the
tests pass when they actually run --- is answered: armed locally, 11
m6_5 and 8 m6_8 REPL tests are green, and all six real-LSP tests
(clangd x2, gopls x2, rust-analyzer x2) pass individually. The coverage
was real the whole time. It just never ran.
Linux only for now, deliberately: macOS needs the brew equivalents and
roughly doubles install cost on the slowest matrix leg. The variables
stay unset there, so those tests skip cleanly as before.
Also removes the documentation lane from the ledger. Its disposition
was left undecided pending confirmation that its branch carried
nothing unique; measured, `githubsucks/handoff-2026-07-20` is 1 ahead
and 365 behind, and its whole unique diff is four doc files at 42
insertions against 88 deletions --- merging it would REVERT current
documentation. The section asked whoever confirmed that to remove it.
Gates: fmt; clippy -D warnings; --lib 1863; --lib --features crdt
2048; m4_acceptance 121 (unarmed, per CLAUDE.md); m6_5 11; m6_8 8;
PMACS_REQUIRE_GPU=1 -p pmacs-gpu 202; git diff --check clean.
The entry pasted `4 0`, measured immediately before the commit that
wrote it; at the pushed head the same command said `5 0`. An
ahead-count is self-referential in the file that carries it, so the
entry now pastes only the merge-base — which is stable — and says to
run the count on demand. Behind-count stays the thing that matters,
and the merge-base tells you whether it can still be zero.
Close review round 6 by moving CRDT quarantine to common divergence
detection, guarding every snapshot and later owner-write route, and
making the acceptance pre-image classifications honest.
Advance the active-work lane to the actual integration checkpoint and
replace the obsolete delete-to-insert recovery rule.
The count in the previous commit was measured against `64883eb` and
was stale the moment that merge landed. Re-measured and pasted as
command output. `main` moved twice during this round; the entry now
says so, and says why a stale base matters under branch protection.
Resolution is a deletion, not a rewrite: `main` REMOVED the
`scripts/bite` lane entry when #192 landed, so this side drops it too
rather than resurrecting a merged lane. This lane keeps its own entry;
its pasted position measurement is re-taken in the next commit,
because the merge itself moves it.
The previous commit pasted `git rev-parse`/`git log`/`merge-base` output
showing `main` at `64883eb` and "main IS integrated". #193 merged between
writing that and pushing it, so the pasted output was false in the tree
that carried it --- and "main is integrated" is exactly the kind of claim
this review round was about: the tree asserting something the record does
not support.
Re-measured and re-integrated, and the bullet now says the thing the
first attempt got wrong. Pasting command output is necessary and NOT
sufficient: a base measured before the last push is a claim about a tree
nobody has, so it has to be re-measured at push time and treated as
expired on sight. `main` moved three times inside this one lane
(#187 -> #192 -> #193).
