`!messages.is_empty()` could be satisfied by any unrelated semantic
message, so the row asserted an ordering against a frame it never
confirmed was there. It now requires the unwritten messages to contain
InstanceMessage::PanelFrame(PanelFramePayload::Absent) --- the successor
frame whose own transition raised the release.
The assertion bites: suppressing that payload while keeping the
cancellation fails the row, where the emptiness check would not have
noticed.

Closes the gap recorded through tasks 18 and 19. The third drain sits
inside the daemon's per-frontend frame loop, which no unit row could
enter, so it was written down as owed rather than assumed covered by its
neighbours.
The seam is now `project_semantic_frame`, extracted from that loop. It
returns its messages UNWRITTEN, and that is what makes the ordering
assertable: a caller holding them has by construction not sent the
successor frame, so a release already delivered at that moment provably
precedes it rather than merely arriving alongside it.
The row arms a gesture on a reporting terminal, takes the panel away so
publish_absent_panel cancels from inside projection, calls the seam, and
asserts the child already has the release while the successor frame is
still in the caller's hands.
It bites its own drain and no other: removing the drain from the seam
fails Q5 while Q1-Q4 stay green on the effect and detach drains.
Grid sessions no longer reach the drain at all --- they hold no panel and
no gesture --- which is tighter than the previous per-fid call.
Also folds in the reported prose typo, and records the gate's
precondition: a foreign C++/java build has been at load 114+ through
this work, and the three wall-clock rows that redded under it were green
in isolation every time. Running the gate into that would manufacture
another U6/U9/U10 rotating-red incident.

Answers review of c37c066.
ABSENT WAS MISSING. The approved G5b table has five transitions, not
four, so the matrix was 16 quadrants where it should be 20. Added, and
it earns its place twice: as the fifth row, and as a CONTROL on SS5b's
own cancellation --- removing that cancel now fails the Absent quadrants
while the four this lane added still pass.
The quadrant count is asserted in the row. A loop that quietly stops
covering a combination passes exactly as loudly as one that covers them
all, which is the same read-success-from-absence shape as a test filter
that matches nothing.
G5m ASSUMED its composites. Both scenarios asserted one release without
ever checking the mapping moved, so either would pass as a
single-cause transition wearing a composite's name. It now peeks the
generation before and asserts it advanced after --- peeked, because
reading through the authoritative accessor would advance the key and
manufacture the very second cause the row is meant to observe. The
assertion bites: a same-size geometry change does NOT move the mapping,
and substituting one fails the fixture.
The doubled P12 rustdoc line is back and removed again. I wrote the note
about this exact seam after the first occurrence and then spliced
through it a second time. The crate-wide sweep is now a real check
rather than a grep I improvised: every `///` line containing a second
`///` that is not a URL.
Machine note: a foreign C++ build was running at load 114 during the
final verification, and three wall-clock rows redded under it ---
m6_2_pty_streaming_respects_byte_ceiling,
composition_overhead_under_ten_percent and
full_buffer_summary_flatten_scales_on_large_grammar_file --- each green
in isolation. The gate still wants a quiet machine.

Answers review of e2b080f. The transition detection was sound; the rows
proving it were not.
G5b(a)-(c) and G5m stopped at has_pending_release() or a cancellation
count. Both pass while delivery or recorded-domain routing is broken,
and the mutation that parks a release and never delivers it proves it:
it now fails all three rows and previously failed none. Every quadrant
drains explicitly and asserts the effect --- exact release bytes for a
reporting terminal, the cleared empty selection for a document, and an
empty slot afterwards.
The matrix is now the table the framing asks for: four transitions x two
families x two targets, sixteen quadrants. All four earlier rows used
the legacy terminal fixture, so the mapped legs and every document leg
were simply absent.
G5m takes both composites the framing names --- changed-size geometry,
which moves the epoch AND the mapping generation, and a buffer
replacement that also moves the mapping --- rather than the one
wrong-shaped combination it had.
One quadrant asserts less and says so: for window replacement on a
document the window the gesture belonged to is gone, so the completion
has nothing left to clear and the ending is the whole effect. Written
into the row, because a silently absent assertion is how a quadrant
stops testing anything.
Two fixture facts the failures taught: the document legs press at row 0
because foreign_edit replaces buffer contents without refreshing the
window's cached line index, so only the first display row resolves to a
byte and a press that anchors nothing does not arm; and cargo check
--lib does not compile #[cfg(test)] code, which is why a missing test
helper passed a check and failed the build.
Corrects two records. The ledger had the mutation labels reversed ---
dropping the BUFFER comparison misses the buffer transition, not the
window one. And semantic_render still told readers these transitions
were left armed on this branch, which was true of SS5b and false here
since the matrix landed.

Task 19. SS5b wired Absent and left the other four transitions armed,
inert while nothing consumed the latch and defects the moment
cancellation gained an effect.
Three are visible in the producer, where the declaration is built: the
side WINDOW replaced, its BUFFER replaced, and the GEOMETRY epoch moved.
The last needed a retained geometry_epoch on PanelPresentation, because
nothing else the producer holds moves with a same-size geometry change
--- not the panel epoch, not the identity, and on a legacy peer not a
mapping key either --- so the transition was invisible and a live gesture
survived a grid it no longer belonged to. DETACH cancels in the
dispatcher, before any teardown, because it is the transition with no
later opportunity of any kind.
The release follows the RECORDED domain, so a buffer replacement pays
the child the gesture was pressed on rather than whatever occupies the
panel now.
G5b(a)-(d), G5m and G5j, each reading the child's byte stream or the
document's selection rather than the latch. The mutations discriminate
exactly: dropping the window half of the identity check fails only the
buffer leg, dropping the buffer half fails only the window leg, dropping
the geometry check fails only that leg, and dropping detach's cancel
fails only detach.
G5m survives all four, and correctly --- two coincident causes take the
same latch, so one release, and removing either cause still leaves one.
G5j's two legs differ and the row proves it: an empty selection is
cleared without moving point, while a real dragged region survives
anchor-and-cursor exact. Clearing every selection fails the second leg,
which is the mutation that matters --- ending a gesture is not a reason
to discard what the user selected.
Machine note: a foreign java build was running at 213% CPU during this
work, and the wall-clock budget row composition_overhead_under_ten_percent
redded twice under it, green in isolation both times. Functional rows
are unaffected; the gate should wait for a quiet machine.

The Q6 rewrite spliced its replacement text ending with P12's heading
while the slice it replaced began with the same line, concatenating both
copies onto one line. Neither cargo fmt nor clippy reflows doc comments,
so nothing downstream noticed.
Swept the rest of the crate for the same shape; the only other hit is a
`file:///` URI inside a legitimate doc line.

Answers review of ab8ddae. The entry drain could not close this: it
looks for an OWED release, and a gesture that is still LIVE owes nothing
yet. Arming was what cancelled it, and arming runs after the replacement
press has already reached the target --- so a second press with the first
never released put `old press, new press, old release` on the wire. Two
presses outstanding, then a release arriving for the wrong one.
The Down arm now ends the live gesture and drains it before applying the
replacement, so the child sees `old press, old release, new press`.
The invariant moved to where it is relied on. arm_accepted_gesture now
asserts that neither a live gesture nor an owed release remains, at the
point of ARMING rather than inside cancellation --- arming is what the
ordering protects, and checking during cancellation cannot see the case
where nothing has been cancelled yet. The defensive cancel stays for
release builds, because parking late is recoverable and overwriting is
not.
Q6 was rewritten, because the old one never sent a second press while
the first was live and so could not observe any of this; its final
assertion also ran after a further cancellation. It now expects the
exact bytes `release(1,2), press(2,4)` in that order.
Both layers are witnessed separately. Reverting the ordering trips the
new debug assertion at the point of arming; reverting it AND compiling
that assertion out --- which is what a release build does --- fails the
byte-order assertion instead, with the child receiving only the new
press.

Task 18. Cancellation now PARKS the record instead of returning it into
a context that drops it: two of the three cancellation sites --- the
mapping-generation advance and publish_absent_panel --- run inside frame
production, where no target effect can happen, so the gesture ended with
the child still holding its button.
A SLOT, not a queue. The latch holds at most one gesture per frontend,
so at most one release can be owed, and the bound is structural rather
than a cap someone chose. Overwriting a still-parked release is a
debug_assert rather than a silent loss --- a backstop, since the ordering
is what actually prevents it.
Three drains, each against a specific way the release would otherwise
arrive too late or not at all: before any subsequent panel-pointer
effect, before detach teardown (the next statement in that arm drops the
state holding the record), and at the projection seam between
render_frame returning and its messages being written.
Q1, Q2, Q3, Q4 and Q6, each biting its named mutation with the run
counts checked. The mutations discriminate: dropping the park fails all
three delivery rows; removing the effect-drain spares Q4, which has its
own; removing the detach drain hits Q4 alone. Q3 asserts ORDER rather
than arrival, and the mutation that keeps the drain but moves it after
the press effect fails exactly that assertion, with the child's stream
coming back press-then-release.
Q5 IS OWED, AND RECORDED AS SUCH. The projection-seam drain needs a row
that drives the real per-frontend frame loop; these rows call
render_frame directly and never enter it. The seam still matters --- a
cancellation with no following panel event and no detach would let the
successor frame overtake the release its own new mapping required --- so
it is written down as unwitnessed rather than treated as covered by its
neighbours.
Two fixture facts worth keeping: the Q rows cancel through Absence
rather than a mapping advance, because a terminal panel's key tracks its
screen and anchor, not its buffer, so a foreign edit does not move it;
and the helper re-shows AND re-declares the panel, because a panel left
Absent fails the inbound ladder and the row would then be observing the
ladder rather than the slot.

Answers review of 557ea6d. Capturing the outcome and asserting it LAST
makes the focus assertion reachable: removing the buffer check accepts
the press, an accepted press activates the panel before it replays, and
the row now fails on focus --- WindowId(3) against WindowId(2).
I had recorded this as a limit of the type boundary, claiming no
mutation could reach the effect assertions because the daemon applies
only on Accepted and the disposition gives Refused no target. That was
wrong. The obstacle was that the row asserted the refusal BEFORE
dispatch and aborted there. Ordering, not architecture.
The classification is still checked, at the end, so the row cannot go
vacuous if it ever stops testing a refusal.
Controller and byte assertions stay documented as defence in depth, and
now for an accurate reason: the mutation that reaches them routes
through a document buffer, which touches neither.
Also replaces failure text that still described an out-of-range anchor,
which this fixture stopped using when its refusal lever became a foreign
buffer.

Answers review of 9028e1b.
P2 recorded `active_frontend`, which is which FRONTEND is current, not
which window has focus. Focus is `views[&fid].active` and `focus_window`
moves it, so the row would have watched a panel steal focus without
noticing. It now records the focused window, and asserts up front that
the panel does not already hold it --- otherwise "focus did not move to
the panel" asserts nothing.
P2's refusal lever also changed, because the old one could not exercise
what the row claims. An out-of-grid cell with the row bound removed
becomes `on_chrome`, so the press classifies Consumed and still reaches
no target: the row bit on its own precondition while focus was never
touched. A foreign buffer at an in-content cell is the refusal whose
mis-gating actually yields Accepted.
And the row now says what is falsifiable about it. Removing the buffer
check makes the press Accepted and P2 fails --- but on the precondition,
which fires first, so the focus, controller and byte assertions cannot
fail under that mutation and no other mutation reaches them: the daemon
applies only on Accepted, and the disposition enum gives Refused no
target to apply. They are defence in depth against a future refactor,
labelled as such rather than presented as coverage.
The ledger claimed every row reads a target effect and never the latch
alone. That was false. P9 and P10 read the LATCH, and correctly so ---
the defect they fence is a record existing for a gesture that never
began, so the record is the artifact, and an effect assertion would not
distinguish their mutations. The line now separates effect rows from
arming-gate rows and names P2's third case.

Answers review of 2ea39aa. Two of my claims were wrong and the code
disproved them.
WIDE PANELS HAD DEAD POINTER INPUT. A panel deliberately does not
inherit the terminal's per-axis PTY caps (Bet B5'), and the renderer
clamps through terminal_projection_size so a band wider than
MAX_TERMINAL_COLS paints correctly. Pointer routing passed the RAW panel
width, and view_status_for_size refuses anything over the cap --- so on
exactly those panels every click inside the visible terminal resolved to
None while the band looked perfectly normal. Routing and the recorded
viewport now go through the same clamp, with P12 as a POSITIVE control
at MAX_TERMINAL_COLS + 128.
P10 IS REACHABLE, and my note saying otherwise was wrong. I claimed
anchor_at resolves every in-grid cell of a live view, "measured, not
assumed". I had measured ROWS and generalised to cells. anchor_at
refuses coord.col >= row.cells.len(), and the fixture's band is 80
columns over a 20-column child, so columns 20..79 are painted padding
inside accepted content. The row exists now and the begin_selection gate
is witnessed rather than excused.
THE DISPOSITION IS AN ENUM. As {outcome, Option<target>} the invalid
pair --- refused, yet carrying a target --- stayed representable inside
editor.rs, so my "the type makes it impossible" was also wrong. Refused
now holds no target at all. ResolvedPanelTarget is public as a type and
opaque as a value: every field stays private, so the daemon hands the
disposition back rather than reading a derivation out of it.
P2 also now asserts what it observes: the classification is Refused, and
focus and terminal-controller ownership are preserved. A misclassified
press focuses the panel and claims the controller BEFORE its
out-of-range anchor fails, so byte and latch assertions alone stayed
green through exactly that bug.
MY MUTATION HARNESS WAS READING SUCCESS FROM SILENCE. `cargo test --lib
"r4_p\|g5k_"` is a literal substring filter, not a regex: it matched
nothing and ran ZERO tests, and I read the absence of failures as
"the mutation did not bite". One whole round proved nothing. The harness
now prints the run count and says so loudly when it is zero. Re-run
properly, all three fixes bite their named rows.
Also updates the ledger's witness list, which omitted P2, P9, P11, the
recorded viewport and the exact-byte strengthening.

Answers review of 48057d7. The G5k routing fix held; the record still
leaned on ambient state in three places.
TerminalLocal now records the accepted content VIEWPORT. Replay fetched
the current panel_grid_size and returned when it was None --- which is
exactly what a hidden or absent panel produces, so a cancellation could
not finish the drag it was cancelling, and a size-changing cancellation
would have finished against the successor's geometry.
A press that anchors NOTHING no longer arms. The document path returned
Some(Document) unconditionally even when panel_cell_byte found no byte,
and the terminal path returned Local while discarding begin_selection's
answer. Both now report what actually began.
The child rows assert EXACT BYTES rather than a count: a wrong event or
encoding passed the old length checks. The literals are written out
rather than built with the encoder's own formula, which would only
assert that the encoder agrees with itself. G5k(b) pins the ruling that
the SGR framing comes from the record while the modifier bits still
report live state, so its release carries code 4 rather than 0.
New rows: P2's effect half (a refused press reaches no target), P9 (a
document press that anchors nothing does not arm), P11 (a recorded local
completion still runs with the panel HIDDEN, which is what the recorded
viewport is for).
THREE ROWS IN THIS ROUND WERE VACUOUS BEFORE THE MUTATIONS CAUGHT THEM,
and the fixtures now assert their way past each cause. The panel grid in
this fixture is FOUR rows, so content is rows 0..=2: my first P9 and P10
cells were out of grid and refused before reaching the path they claimed
to test, and P9's earlier cell clamped to byte 0 instead of failing to
anchor. Both rows now assert the disposition is Accepted before
asserting anything about the effect.
P10 IS DELIBERATELY ABSENT AND RECORDED AS UNWITNESSED. The
begin_selection gate has no reachable false branch through the daemon:
classify has already established the buffer is the side window's live
terminal, and anchor_at resolves every in-grid cell of a live view ---
measured on the fixture, not assumed. The gate is kept as insurance and
the gap is written where the row would have been, rather than covered by
something that would pass whether or not the gate existed.
P2's effect half is likewise not falsifiable by any mutation I could
construct, because a Refused disposition carries no resolution, so no
path can apply it. That is a stronger guarantee than a test, and it is
stated rather than dressed up as coverage.
Also corrects the last false ledger tense.

Answers review of 39b6fa7. The three-state disposition was sound; the
record and effect half downstream of it were not.
apply_panel_pointer returned a bare bool, so the record carried neither
the resolved target nor the reporting contract, and the daemon drove
accepted Drag/Up back through the mode-sensitive adapter. That adapter
re-reads Shift, the scrollback position and the child's mouse modes on
every event --- which is G5k's named mutation verbatim. A press reported
to the child followed by a release re-evaluated after the child turned
reporting off leaves that child holding a button down; the reverse
transition sends a child an Up for a Down it never saw. The recorded
completion had the same defect and additionally re-derived the current
side window, returning when it had changed --- precisely the transitions
task 19 must terminate, so the completion they need was the one thing
that refused to run.
The press now resolves a PanelGestureDomain --- Document{window},
TerminalChild{window, buffer, modes} or TerminalLocal{window, buffer}
--- and the record carries it. Tails and completions route through
replay_panel_gesture_in_domain, which gates on nothing: not Shift, not
the scroll position, not the child's current modes, not the panel's
current identity. apply_terminal_gesture reports which way it routed so
the domain is measured where the branch is taken. Arming now requires an
effect: a press the target refused records nothing.
G5k(a)-(d) plus P3's reporting leg, P4 and P5. Every row reads a TARGET
EFFECT --- the child's byte stream in order, the terminal drag state, or
the document selection --- never the latch. Each bites its own mutation,
and G5k's four legs all fail under the framing's own named mutation
applied verbatim.
Two seams exist because nothing else exposes what the child received: an
opt-in child-input tap, off by default, and a drag-state read.
Also corrects the recovery ledger, which still said implementation was
paused and the bool collision unfixed.
Records for the ci-red registry rather than hiding it: during this work
composition_overhead_under_ten_percent and pty_mode_child_sees_a_tty
redded together in one --lib run at load 21 and each passed in isolation
immediately after --- U9's signature, and neither path is touched here.

Replaces the panel dispatcher's `bool` with a three-state
PanelPointerOutcome decided BEFORE any target effect, and moves the
gesture lifecycle into one table in the daemon.
The old shape could not express the rule it needed. It validated,
classified and mutated in one pass, so an Up or Drag with no accepted
Down had already reached the child or the selection by the time the
daemon consulted the latch. classify_panel_pointer now returns the
disposition and carries the resolution it was decided from;
apply_panel_pointer acts on that same resolution, so the editor stays
the only authority and the daemon never re-derives chrome, target kind
or content bounds.
The table: a chrome press begins nothing; a left tail with no live
record is inert; an Accepted release performs the ordinary in-content
completion and takes the record; a Consumed release did not reach
content, so it terminates from the record at the gesture's last valid
content cell. Never both --- that is P5.
apply_terminal_gesture now returns whether the gesture REACHED THE
CHILD, so the latch is armed from the effect result rather than from a
prediction about the modes. complete_panel_gesture routes both terminal
domains back through that same shared path, which is what keeps "what a
release does" from having a second implementation.
Four witnesses, each reading a TARGET EFFECT and not the latch, and
each biting its own mutation: P1 chrome press (classify chrome as
Accepted), P3 chrome release on a terminal (drop the recorded
completion), P7 orphan release (remove the Up live-gate), P8 orphan
drag (remove the Drag live-gate).
Two of those rows were vacuous when first written and are recorded here
because the mutations are what caught them. P8 dragged over an EMPTY
panel buffer, so panel_cell_byte returned None and point could not move
whether the gate was there or not. P3 was written against a document
panel --- but R-c lets document chrome Up fall through to content, so it
classifies Accepted and never reaches the Consumed path it claimed to
test; it now uses a terminal panel, on the legacy arm, because reading
the live mapping generation ADVANCES the key and SS5b wired a key
advance to cancel the live gesture, so the mapped fixture destroyed the
gesture it was trying to complete.
Adds view_is_dragging_for_test, the observable that separates a
delivered completion from a latch that merely emptied.
Also re-homes a doc paragraph that described peer_uses_mapped_panel_family
while sitting above update_accepted_gesture; deleting the latter's doc
with the function made the misplacement visible.

The merge commit b758c2e DOES NOT COMPILE, and its message says
"Workspace compiles clean, all targets, no warnings". That claim is
WITHDRAWN. It was true of the tree I checked and false of the tree I
committed.
What happened: I staged the conflict resolution, ran cargo check, hit
`cannot find value mods in this scope` at the mapped arm, edited
src/daemon.rs to bind it, re-ran cargo check clean --- and then
committed without re-staging that file. The verification and the commit
were of different trees. This is the same defect class as gating one
step of an edit-then-commit chain and leaving the next ungated: a
commit that does not depend on the edit it claims.
The fix itself is unchanged from what was verified. SS5b left `mods` in
`..` on PanelPointerMapped; the mapped family carries the same
modifiers, so leaving it there gives a v25 session the inverted Shift
behaviour that parent 48 R-a fixed for v24.
Verified at THIS commit, after staging: cargo check --workspace
--all-targets, no errors and no warnings.
Not amended away. b758c2e stays in history with its false claim
standing and this withdrawal attached, because erasing a bad record is
worse than carrying a corrected one.

Merged rather than rebased, by decision: the lane's 12 commits include
10 framing revisions that all touch the same 800-1000 line doc regions,
so a rebase meant twelve rounds of large-block conflict resolution ---
the operation that produced a committed diff3 marker on the last lane.
One pass instead, with all 12 commits preserved.
Resolutions:
- src/daemon.rs --- took main's structure whole, both inbound arms with
the latch gated on the dispatcher's answer, and threaded replay's
`mods` through both call sites. `mods` is newly BOUND in the mapped
arm, which SS5b left in `..`; the mapped family carries the same
modifiers, so leaving it would have given a v25 session the inverted
Shift behaviour that parent 48 R-a fixed for v24.
- pmacs-gpu/src/main.rs --- additive throughout: both new struct fields
(`gesture_last_content_cell`, `last_pointer_generation`), both resets
at each site, and both test blocks.
- src/editor.rs --- auto-merged; the merged dispatcher keeps SS5b's
`#[must_use]`, its four rejection paths and its `-> bool`, plus
replay's `&mut self`, `mods`, chrome/mode-line handling and terminal
gesture application.
- docs/active-work.md --- the active replay lane above main's corrected
#239/#240/#242 headers.
- docs/bottom-panel-framing.md --- 5a then 5b. The paragraph arguing
the v25->v26 bump should be "recorded as required rather than made"
is marked superseded: SS5b made it and merged as #242.
Workspace compiles clean, all targets, no warnings.
THE MERGE SURFACES A SEMANTIC COLLISION THE FRAMING MUST RULE ON, and
it is not resolved here. The two branches give the dispatcher's bool
different meanings: for SS5b `true` means the gesture was ACCEPTED, and
it drives the accepted-gesture latch; for replay `true` means the event
was CONSUMED HERE, including chrome swallows. So a press on the band's
mode line now returns true and ARMS the latch --- a gesture that never
began in content, which is the defect class SS5b's review round four
found and fixed. Recorded, not patched, because which rows own the
answer is a framing question and the next revision owes it.

Both inbound panel-pointer arms discarded the bool from
dispatch_semantic_panel_pointer and called update_accepted_gesture
unconditionally. The ladder authenticates the SENDER; only the
dispatcher re-derives the TARGET, so an event can clear every rung and
still be refused --- for an out-of-grid coordinate, an absent side
window, or a buffer that is no longer the one in the side window.
A rejected Down therefore ARMED the latch, so a later authority loss
counted a cancellation for a gesture that never began, and once replay
attaches effects it would deliver a release to a child that was never
pressed. A rejected Up CONSUMED a real armed gesture, so the authority
loss that should have ended it found nothing armed and that child holds
the button down for good. A rejected Down on top of a live gesture was
worse again: arm_accepted_gesture ends what it overwrites, so it also
counted a spurious cancellation.
Both arms now gate on the return. The dispatcher is #[must_use], so the
class cannot recur silently --- clippy runs with -D warnings, making a
future discarded answer a build failure rather than a review finding.
Four rows, g5_substrate_a_refused_{press_never_arms,
release_never_consumes}_on_the_{legacy,mapped}_arm. Each drives the
refusal from a coordinate one past the last grid row and ends in a
positive control differing only in that coordinate; without the control
a row would pass just as well if an unrelated rung had dropped the
event. Mapped rows read the generation through the validator's own
accessor so a mapping-rung refusal cannot masquerade as a dispatcher
refusal. Three mutations, each biting its named rows: ungating the
legacy arm fails exactly the two legacy rows, ungating the mapped arm
exactly the two mapped rows, and relaxing the dispatcher's >= to > fails
all four.
Also removes a committed diff3 ancestor marker this file carried since
8c9afde --- the only one in the branch's 32 commits, and invisible to a
clean-worktree `git diff --check`.
Also withdraws the claim that the local CRDT sweep could not go green.
The full 16-stage gate is green, sweep-crdt included. The two m4_24
failures came from running that sweep outside scripts/gate, where it
inherited TMPDIR=/tmp; /tmp/.git exists on this machine and project
detection walks upward, so both base-resolution rows resolved against
the wrong root. That is the exact hazard #240's isolation exists for.

Found by reading the arming path back after the G5 checkpoint, not by a
failing row. `arm_accepted_gesture` overwrote an already-armed latch, so
a dropped `Up` --- one lost to an outbox that closed under a stall ---
was followed by the next press silently discarding the first gesture's
record, without counting it as a cancellation.
Inert on this base, where records are only counted. Once
`panel-pointer-replay` attaches a child release to each record, the
discarded one leaves a button held down with nothing left to release
it, and the arming code that decides this is this slice's.
Mutation: restore the plain overwrite -> the new row alone.
Also records three CI-red observations from the slice-completion gate,
which is the first entry on this lane with a MEASURED confound instead
of the standing uncontrolled one. Three wall-clock-deadline rows red in
one run --- criterion_1 by 0.12%, a PTY lifecycle race, and a 5s child
-exit deadline --- all green in isolation, the last in 0.15s against
its 5s deadline. `uptime` during the run went 14.02 -> 28.35, from an
unrelated turso test suite on the same machine with one binary at 693%
CPU. Not a controlled experiment, but the same evidence U9's synthetic
-load control was meant to produce, and it points at load.
Two process traps are recorded with them, because both were made here.
The Bash tool caps a command at ten minutes and SIGTERMs it, which the
gate reports as `FAILED (exit 143)` on whatever stage was running and
which reads exactly like a real failure. And `pkill -f <pattern>` kills
the invoking shell when the pattern appears in its own command line, so
the intended target survives while the operator believes it died --- and
here `pkill -f "cargo test"` would have destroyed an unrelated
project's build. Identify by PID.
Verified: `cargo fmt --check`; `cargo clippy --workspace --all-targets
-- -D warnings`; the four §5b G5 rows. The full protocol gate follows on
a quieter machine; the run described above is not evidence for this tree
and is recorded as an observation only.

Three rows that share a shape: each is a gate this slice owns whose
downstream EFFECT belongs to the rebased replay lane.
G10b --- ordering, and a carve-out. `panel_mapping_is_current` now takes
the event kind. Zero is refused FIRST, then coordinate-free wheels skip
the freshness comparison. The order is the row: run the carve-out first
and a sender emitting zeroed wheels faces no check at all, which is an
inbound opt-out through the exempt path. The exemption exists because a
tick changes `view_top` and so advances the key --- the next tick already
queued behind it echoes the previous generation, and without the
carve-out the panel scrolls once per frame and appears dead. It returns
before the read, so a wheel does not advance the key either; advancing
would make a wheel invalidate the press after it.
The framing's carve-out-to-the-carve-out, re-imposing the check for
CHILD-REPORTED terminal wheels where SGR carries row and column, is
replay's. Whether a wheel is forwarded is decided by the reporting mode,
and no panel pointer coordinate is consumed on this base at all.
G11a --- exhaustion fails CLOSED. `saturating_add` froze the key at the
ceiling while the mapping kept moving underneath it: the stale-gesture
hole the key exists to close, with the check still appearing to pass.
Now `checked_add`, and overflow publishes `Absent`, clears input
authority, and latches for the session.
G13a/G13b --- `PanelPointerMapped` fell through `coalesce_kind` to
`None`, so pixel-rate mapped motion was lossless and filled the bounded
outbox. Two tags of its own; tail-replacement takes the whole event, so
coordinate and generation advance together and a collapsed run can never
pair a new coordinate with a stale one. Press, release and every wheel
kind stay lossless.
Mutation results, including two that changed the design:
- exemption before the nonzero check -> G10b(zero) alone
- no wheel exemption -> G10b(exemption) alone
- saturating instead of checked add -> G11a alone
- no exhaustion latch -> G11a, but only AFTER the row was extended.
The first version of G11a did not bite: the latch had no proven
job, because the overflow path already returns before storing the
ceiling snapshot, so the next read re-takes the changed arm anyway.
Measured, the two are ALTERNATIVES --- either alone keeps the band
down; only removing both resurrects it. The latch is kept as the
primary because it has a job the ordering does not: `peek` now
honours it, so the peek and the authoritative read agree that an
exhausted session has no key rather than reporting the ceiling.
The source comment says this, rather than the "second half" claim
it made before the measurement.
- mapped variants untagged / one tag for all kinds / sharing the
legacy tags -> the mapped coalescing row alone, three times
Witness-shape note: the two G10b rows call the predicate directly, and
say why. A wheel has no dispatcher-visible effect on this base --- a
document panel focuses on `Down` only --- so asserting focus for a wheel
would prove nothing. Each row carries a press leg, which does have an
effect, to show the predicate is wired into the production arm.
Verified: `cargo fmt --check`; `cargo clippy --workspace --all-targets
-- -D warnings`; `cargo test --lib` (1959); `cargo test -p pmacs-gpu
--bins` (275); both `bottom_panel_stage2b_*` suites (39); `git diff
--check`. `composition_overhead_under_ten_percent` red once during this
work and green in isolation --- a second occurrence of a signature the
lane ledger already carries, now recorded there.

G5a is the one G5 row this slice owns: the mapping key advancing must
raise cancellation at the advance, not reactively when a later event is
refused. Reactive cancellation loses a race --- if the successor frame
reaches the frontend before the physical `Up`, the producer clears its
latch and the cancelling event never arrives.
Cancelling requires something to cancel, so the accepted-gesture latch
lands with it: `AcceptedPanelGesture` (button, coord, buffer, and
whether the press reached a child) in a per-frontend slot on
`SemanticRenderState`, armed from the daemon's accepted inbound arms
after every gate has passed.
Writing that code decides three things the framing's deferred rows later
assert about, so they are pinned here under SUBSTRATE names rather than
under G5c/G5d/G5g/G5p. Those IDs stay on `panel-pointer-replay` per
SS5b's split table --- each asserts something about a synthetic release
or a real drag continuation that does not exist on this base, and
claiming an ID in two branches is the merge hazard `active-work.md`
already records surviving a clean merge once.
Two consequences are recorded rather than fixed:
- Cancellations are COUNTED, not queued. The record queue is what
replay drains to deliver each release; landing it here would grow
one entry per cancelled drag with nothing ever draining it. A
saturating count is bounded and still separates a consume from a
cancellation.
- The other G5b transitions --- panel epoch, buffer replacement,
same-size geometry, detach --- leave the latch armed on this base.
Each strands a live gesture whose release can never be accepted.
That is inert while nothing consumes the latch, and becomes a defect
exactly when replay supplies effects, in the branch that owns the
row. `Absent` is wired anyway, because `publish_absent_panel`
clears input authority two lines later; leaving it out would be an
inconsistency inside one function rather than a clean deferral.
Five mutations, each biting only its named row:
- drop the advance trigger (reactive cancellation) -> G5a alone
- arm on every accepted pointer event -> the arming substrate alone
- an ordinary `Up` no longer consumes -> the arming substrate alone
- a consume counts as a cancellation -> the arming substrate alone
- one global latch via a shared slot -> the ownership substrate alone
Also repairs a fourth rustdoc split on this branch. Inserting
`AcceptedPanelGesture` at what read as a blank gap adopted
`SemanticRenderState`'s doc comment AND its
`#[allow(clippy::struct_excessive_bools)]`, silently un-suppressing a
lint on the struct that needed it. Same mechanism all four times; the
ledger now records the check as "look UP from the insertion point".
Verified: `cargo fmt --check`; `cargo clippy --workspace --all-targets
-- -D warnings`; `cargo test --lib` (1956 passed); the two
`bottom_panel_stage2b_*` acceptance suites (39 passed); `git diff
--check`. The full eleven-stage `--protocol` gate is reserved for slice
completion per the standing procedure.

The G6/G7/G8 matrix, plus the probe correction and the corrections
review found in my first attempt at these rows. This is the coherent
checkpoint: full eleven-stage `--protocol` gate, green.
**THREE OF THESE ROWS PASSED WITHOUT PROVING THEIR CLAIM**, and each
failed differently:
G8b/G8d had no atomicity. G8b installed a LEGACY frame and then
switched the session to Mapped, so `mapping_generation` was `None`
throughout --- asserting it stayed `None` after the refusal asserted
nothing. Each direction now uses an independent state, accepts a
CORRECT-FAMILY baseline so there is real authority to preserve, and
primes both pointer latches. Two new mutations pin it: clearing
authority before refusing fails G8b, discarding the retained frame
fails G8d. The family-gate mutation touched neither.
G8e covered one direction. An authority check that only holds one way
is one a peer walks around by choosing which identity to forge, so a
mapped session now also fails to borrow a legacy identity --- and
BOTH claimed identities have real registered sessions, or a
payload-keyed lookup fails for want of a session rather than for want
of authority. That was why G8e's own named mutation did not bite on
the first attempt.
G6b measured ambient state. It pre-focused the panel and then asserted
against `active_window_id()`, which tracks `active_frontend` too ---
satisfiable by a frontend switch that never routed anything. Every
routing and refusal row asserts `views[fid].active` now, with the
document precondition stated rather than assumed.
**And the probe measured the payload rather than the band, twice over.**
Its identity tuple was `(panel_epoch, geometry_epoch, size)`, which
ordinary content, focus, cursor and generation updates all leave
unchanged --- so accepted frames went uncounted, including the
identical-frame/higher-generation case this slice requires, and a
fixture waiting for two frames would wait forever. It snapshots the
complete accepted authority now, `(presented frame, mapping_generation)`,
and keeps the raw payload kind ONLY to tell a real `Absent` from a
refusal: inferring absence from `presented() == None` turned a rejection
into "the daemon says there is no band", a different fact entirely.
Nine rows, ten mutations, each biting its own:
G6a legacy outbound G7a mapped outbound, live generation
G6b legacy inbound routing G7b mapped inbound routing
G8a bare from v25 refused G8c mapped from v24 refused
G8b legacy at v25 refused, atomically
G8d mapped at v24 refused, atomically
G8e both forgery directions
plus: an Unsupported session accepts NEITHER family
G6c/G7c remain replay-lane effects.
**The gate earned its keep**: it caught a real regression I would have
shipped. `one_daemon_serves_a_v21_panel_session_and_a_shipped_v20_client`
counter-offers `PROTOCOL_VERSION`, now 25, so it is a MAPPED session
whose helper drained for legacy `Present` and timed out. Third suite
whose helpers assumed one family --- daemon acceptance, the GPU probe,
now GPU acceptance --- each written when only one family existed and
each quietly deciding what "a panel arrived" means.
Four `--protocol` runs were needed. Three failed on unrelated
signatures: the composition budget twice, in different steps, and
`setsid_escapee_is_not_reaped_and_teardown_reclaims_readers` once, a
new signature. All are recorded in the lane ledger rather than
`ci-red-signatures.md`, which ends at U9 here while the unmerged replay
branch already holds a U10.
Gates: all eleven green under `env -u TMPDIR` with `--protocol`,
log 20260815T185708Z, verified by exit status.

Three review corrections ahead of the witness rows.
**THE LEGACY CONTROLS NEGOTIATED TWO DIFFERENT VERSIONS AT ONCE.** I
moved their `SessionRegistry` to v24 and left their retained
`SemanticRenderState` on `PROTOCOL_VERSION`, so the producer shipped
`PresentMapped` to a session the daemon believed was v24. The rows
passed, which is the problem: a control that negotiates two versions
proves nothing about either. Five producers across the four rows now
take `LEGACY_PANEL_VERSION`, the same constant the registry does.
**The boundary is a LITERAL 24, not `PANEL_MAPPING_MIN_VERSION - 1`.**
G6/G14 make the family boundary absolute; arithmetic against a moving
constant would drag these rows forward on the next bump and they would
silently begin testing v25 as "legacy".
**And I split a rustdoc from its function again.** Inserting
`peer_uses_mapped_panel_family` above `peer_may_send_panel_events` left
the latter's doc block stranded, so my function inherited two
incompatible descriptions and the documented one had none. Same mistake
as `screen_size` two commits ago --- inserting an item at what looks
like a blank line between declarations, when the line above is the next
function's documentation. Each block sits directly above its own
function now.
Verified by EXIT STATUS, not by reading filtered output: `cargo test
--lib` 0 (1945 passed), clippy 0, focused suite 0 (37 passed). The
`composition_overhead_under_ten_percent` flake appeared once mid-run
and passed isolated; it is the known wall-clock budget signature, not
this diff.

The receiving half of bilateral gating, plus the constructor fix review
found. The eight G6/G7/G8 witness rows and the GPU side are next; the
full eleven-stage `--protocol` gate runs once they discriminate.
**THE FAMILY IS DECIDED FIRST, FROM THE AUTHENTICATED SESSION.**
`peer_uses_mapped_panel_family` reads `session_state(source)`, never the
payload's `frontend_id` --- that field is untrusted on every inbound
variant, and looking negotiation up by it would let a peer claim
another session's family. The order is stated at both arms: family,
then the existing epoch ladder, then the mapping generation, then
dispatch. It cannot depend on the variant's contents, because it
decides which variant is admissible at all.
Both wrong-family cases are REFUSALS, not fallbacks. A `>= v25` session
sending the bare `PanelPointer` is dropped rather than handled under
legacy semantics --- handling it would leave the mapping hole reachable
by choosing a discriminant, which is the entire bypass. A `<= v24`
session sending `PanelPointerMapped` is dropped too, even though a peer
compiled from this crate can encode the discriminant: negotiation is a
gate, not a sender convention.
`panel_mapping_is_current` is the ladder's finest rung. `buffer_id`
catches an A->B replacement, `panel_epoch` a close/reopen,
`geometry_epoch` a declaration race, and this catches the text under
the cell changing --- a foreign edit, a fold, a reload, none of which
moves an epoch. Zero is refused outright, and the check reads through
the same accessor projection stamps with, so the two cannot drift.
**And `new()` contradicted its own contract.** It documents a
current-build peer and enables every other current capability, but I
initialised `peer_knows_mapped_panel` to `false` --- so an implicitly
current peer was sent the LEGACY family. Set true, with the doc
extended to say the assumption covers later capabilities too.
**Four daemon rows broke, and that is G8a firing.** They drive
`FrontendEvent::PanelPointer` through sessions negotiated at
`PROTOCOL_VERSION`, which is now 25 --- so the bare variant is refused,
correctly. They negotiate `LEGACY_PANEL_VERSION` now, which both fixes
them and makes them explicit legacy positive controls rather than rows
that happened to pass.
Note for the eventual rebase: this branch is based on main, where
`dispatch_semantic_panel_pointer` still takes four arguments. Threading
`mods` is R-a, owned by `panel-pointer-replay`; the mapped arm
destructures `mods` into `..` here and will pass it through when the
lanes meet.
Verified: focused suite 37/37, `cargo test --lib` 1945 green, clippy
clean.
**Amended.** The first version of this message claimed the lib suite
green when it was not: I piped `cargo test` through `tail`, so the
pipeline exited 0 and my `&&` chain committed on a failure I had not
read. The four rows above are what it was reporting.

The producer half of bilateral gating. Inbound routing, the four
refusal quadrants and the positive routing controls are the next
commit; the full eleven-stage `--protocol` gate runs at that
checkpoint, once all of them discriminate.
`SemanticRenderState` gains `peer_knows_mapped_panel`, set in
`for_peer` beside the six existing capability bools --- the pattern
this codebase already uses to bake a negotiated version into the
producer. A `>= v25` peer receives `PresentMapped`; every older peer
receives legacy `Present`, unchanged.
**THE ORDERING IS LOAD-BEARING AND IS WRITTEN DOWN AT THE SITE.**
Projection first, THEN capture-and-advance the mapping key, THEN
construct the payload. A terminal projection registers the view whose
scroll anchor the key reads, so capturing earlier stamps a frame with a
key derived from an anchor that does not yet exist.
One case is deliberately not a fallback: if a `>= v25` peer has no
presentable mapping to stamp, the producer publishes `Absent` rather
than dropping to legacy `Present`. Falling back would hand a peer the
family it did not negotiate --- the bypass the gate exists to close,
arriving from the daemon's own side.
**Thirty existing rows broke, and that is the gate working.** The
fixture negotiates `PROTOCOL_VERSION`, so every panel test suddenly
received the mapped family where it matched `Present` literally. Those
rows are about the PROJECTION, not the wrapper, so the fixture helpers
are family-agnostic now and which family carries a frame is pinned by
the G6/G7/G8 rows rather than incidentally by thirty others.
Verified: focused suite 37/37, `cargo test --lib` 1945 green, clippy
clean.

Three of the four terminal gaps. The fourth is recorded as owed rather
than faked; see below.
**THE STABLE CLASSIFICATION WAS INCOMPLETE.** Cursor motion still
advanced the mapping revision: `restore_cursor`, `horizontal_tab`,
`move_vertical`, `move_horizontal`, `set_col` and `set_row` all called
`changed()`. Moving the caret denotes nothing new, and a child that
merely repositions its cursor would have cancelled a drag. All six take
the display-only path now.
Worse, **rewriting the same glyph under another style advanced it**,
which is precisely the control SS5b requires to hold. `write_character`
now compares the glyph before writing --- sampled BEFORE
`clear_wide_at`, which blanks a cell that is part of a wide pair and
would otherwise make every rewrite look like a change. That ordering
was found by instrumenting the failing row, not by reading the code.
**THE SNAPSHOT CARRIED DOCUMENT-ONLY STATE FOR TERMINALS.**
`view_top`, `view_left`, wrap, content columns, fold policy and folds
describe a document projection and take no part in a terminal's, where
the child's screen decides the mapping. They live inside the `Document`
arm now; only common geometry --- buffer identity, rows, columns ---
stays outside.
**AND THE REVISION WAS NOT PUBLICATION-CONSISTENT.**
`view_mapping_identity` read the LIVE screen revision while
`projection_ref` returns the last PUBLISHED cells, so buffered output
under synchronized-output would stamp displayed cells with authority
they were never painted under --- a frontend echoing a generation
matching nothing it can see. `ScreenProjection` carries
`mapping_revision` now and the published value is what is read.
**The witnesses were separated across the seam**, which review named
exactly: `screen.rs` proved the counter, the daemon proved enum
selection, and a `view_mapping_identity` returning a constant would
have left both green. A daemon-level row now drives real events through
a panel terminal and asserts the daemon's generation moves on a new
glyph and holds across a style-only rewrite and across cursor motion.
**OWED, NOT DONE: the scroll-anchor row.** The anchor is in the key,
but three attempts failed to drive a scroll from this fixture ---
`scroll_lines` wants a viewport the projection registers on its own
schedule, and `scroll_view` with an explicit size reports no movement
after forty line feeds. Recorded in the ledger rather than faked or
quietly dropped: without it, a constant ANCHOR alongside a live
revision still passes every terminal row that exists.
The two test hooks are `#[doc(hidden)] pub`, not `#[cfg(test)]`,
because the rows needing them are integration tests and those link the
library without `cfg(test)`.
Verified: focused suite 37/37, `cargo test --lib` 1945 green, clippy
clean.

All four closure gaps in one correction. Three of them are defects in
what I committed as G1-G4; the fourth overturns a claim I made about
what could not be witnessed.
**THE KEY IS NOW EXACT, NOT PROBABILISTIC.** It was a `DefaultHasher`
digest, so authoritative equality rested on the absence of collisions
--- and a collision silently ACCEPTS a stale gesture, which is precisely
the failure the key exists to prevent. It is a `PanelMappingSnapshot`
struct compared structurally now. The emitted `mapping_generation`
stays a `u64` on the wire; only the daemon's own comparison changed.
**THE TERMINAL DOMAIN WAS ABSENT, AND THE BUFFER REVISION WAS WRONG.**
The key hashed the panel buffer's content revision for every target
kind. For a terminal that is doubly wrong: SS5b says the buffer revision
does not decide the mapping, and what does --- the screen --- was not
consulted at all. `PanelMappingContent` now splits by kind, and
terminals carry the screen's mapping revision plus the view's scroll
anchor.
That revision had to be built. `Screen::generation` cannot serve:
it advances from 39 sites including style, title, bell, tab stops and
cursor motion, none of which changes what a coordinate denotes.
`Screen` now carries `mapping_revision`, and the classification FAILS
SAFE --- `changed()` bumps both by default, and only the eleven
explicitly display-only arms call `display_only_changed()`. Anything
unclassified is treated as content, because over-cancelling a gesture
is a nuisance while under-cancelling one lets a stale coordinate reach
a child.
**"NO PRODUCTION PATH REACHES A TRANSPOSITION" WAS WRONG.** I recorded
the rows/cols product mutation as unwitnessable and kept the separate
hashing on principle. Resize plus redeclare reaches it: 4x80 -> 8x40
holds the area at 320 while swapping the dimensions, and
`last_content_cols` is not refreshed until the next render, so the two
grid fields are isolated. The row exists and the product mutation now
fails.
**G3 WAS INCOMPLETE.** It covered idle and cursor only. Focus is added
at the daemon level --- the tempting error is folding the whole frame,
which carries a `focused` flag, into the key. Styling is pinned
structurally instead: the snapshot has no style field, so there is
nothing a recolour could touch. The terminal controls live in
`screen.rs`, at the level the classification lives, with a positive
half so a revision that never advanced at all cannot pass them.
**AND MUTATION TESTING FOUND ANOTHER UNWITNESSED BRANCH.** Routing
terminal panels through the DOCUMENT arm left all thirty-five rows
green --- the `is_terminal` branch had no daemon-level witness at all.
A row now pins that the snapshot picks its domain by target kind, and
that mutation fails.
Mutations: display-only events bumping the mapping revision (the
screen-level control fails); terminal panels keyed on the buffer
revision (the domain row fails); rows*cols as an area (the
transposition row fails); plus G1-G4's original five, still biting.
Verified: focused suite 36/36, `cargo test --lib` green, clippy clean.
Full `--protocol` gate reserved for the checkpoint after bilateral
gating, per the standing procedure.

The key itself, its domain, and the witnesses for both. No gating and no
replay yet.
**DERIVED FROM A FINGERPRINT, NOT BUMPED AT MUTATION SITES.**
`panel_mapping_fingerprint` hashes what actually decides which byte a
cell means --- buffer identity, grid rows and columns, `view_top`,
`view_left`, wrap mode, content columns, fold POLICY and fold CONTENT,
and the buffer's content revision --- and the generation advances
whenever that changes. This makes the changing/stable split
STRUCTURAL: an input that is hashed moves the key by construction, and
one that is not cannot. Bumping by hand at each mutation site would
have made "advances after any mapping mutation" a promise about
someone remembering.
Folds are hashed at their SOURCE, the registry's ranges, rather than
through the derived `VisibleLineMap`, whose only public summary is
`is_identity()` --- too coarse, since a fold edit that leaves the map
non-identity still changes which source line a row shows.
**ONE SEAM, READ BY BOTH SIDES.** `panel_mapping_generation` advances
if the fingerprint changed and returns the current value; projection
will stamp with it and inbound validation will compare against it, so
"what the frontend was shown" and "what the daemon checks" cannot
drift. Computed ON DEMAND, deliberately: a mutation not yet painted has
still changed the inverse, and a gesture arriving in that gap must be
refused. Deriving from the last emitted frame recreates the hole.
**Nondecreasing, and never cleared.** `Absent` yields no key to stamp
--- which is not a key of zero --- but the high-water mark survives, so
a frame delayed across a hide cannot roll authority backward. First
establishment takes 1; zero is the wire's invalid value.
**MUTATION TESTING FOUND MY WITNESSES UNDER-SPECIFIED, TWICE.**
With only the content-edit row present, dropping `view_left` from the
key stayed GREEN, and so did collapsing the grid to `rows * cols`. That
is exactly what the closure predicted --- "a key that ignores
`view_left` passes every row that only scrolls vertically" --- and it
is why G2 is enumerated per input rather than asserted in aggregate.
Six legs now, one per input, each touching only its own.
Mutations that bite: omit the content revision (3 rows), omit
`view_left`, omit wrap, omit fold policy, and include the CURSOR --- a
stable input, caught by G3.
**One mutation does NOT bite, and the row says so rather than
pretending.** Collapsing rows and columns to a product stays green,
because `last_content_cols` co-varies with a column change and the row
count co-varies with a resize: the key moves by another input either
way. Only a transposition (2x6 -> 6x2, identical product) would isolate
it, and no production path reaches one --- rows come from the band's
height, columns from the frame declaration, and nothing swaps them. The
key hashes them separately anyway; hashing a product because no test
can currently tell the difference would be choosing the weaker
construction for the suite's convenience.
G4b --- that an in-flight drag survives a selection repaint through
real replay --- stays owed by the rebased replay lane, which is the only
branch where replay exists.
Verified: focused suite 34/34, `cargo test --lib` green, clippy clean.
Per the standing procedure the eleven-stage `--protocol` gate is
reserved for the next coherent checkpoint.

SS5b's first implementation commit: the two appended variants, the
version constants, and the pins that hold them in place. No gating, no
key, no replay --- those are the next commits, and the variants are
REFUSED everywhere until their gate lands.
**APPENDED AT THE TRUE END, confirmed by the discriminants.**
`PanelPointer` is 15, `TextInput` 16, `PanelPointerMapped` **17**;
`Present` 0, `Absent` 1, `PresentMapped` **2**. "Beside `Present`" would
have been adjacent insertion, which shifts every discriminant below and
silently re-interprets an older peer's bytes. `mapping_generation` is a
`u64`, last within each variant, documented invalid at zero --- the
value a default-constructed sender produces, so accepting it would let
a peer opt out of the check by sending nothing.
**THE COMPILER NAMED EVERY SEAM.** Four non-exhaustive matches:
`semantic_render`'s declaration accessor now sees through both
families, and the three routing sites REFUSE the mapped variant rather
than unwrapping it to legacy meaning. Refusal is the correct default at
an intermediate commit, not a placeholder --- until the frontend can
prove it negotiated v25 it IS a `<= v24` peer for gating purposes, and
painting first would ship a window in which the band is hit-tested with
no mapping identity at all.
**Five mutations, each biting its own rows:**
insert `PanelPointerMapped` before `TextInput`
-> the TextInput pin and the mapped pin. `PanelPointer`'s v23 pin
correctly SURVIVES: its discriminant did not move, which is the
"only the pin whose discriminant moved fails" behaviour G0a
specifies
insert `PresentMapped` before `Absent`
-> the Absent pin and the mapped-frame pin
swap `geometry_epoch` / `panel_epoch`
-> the exact-bytes assertion, while the round-trip stays green.
That is the blind spot G0b exists for, and it is why every
adjacent same-typed field carries a distinct value
bump the wire version without extending the supported set
-> both new tripwires and 1a's v6 ladder
move `ADVERTISED_PROTOCOL_VERSION` to 25
-> the baseline pin
**Version fallout, enumerated rather than discovered one gate at a
time.** Four acceptance-suite tripwires (`bottom_panel_stage2b_gpu`,
`discovery_stage2` x2, `vterm_stage3`, `statusline_segments`) each say
"a wire bump must be a conscious edit here" and each worked. Rather
than fix them one run at a time I grepped the tree for version
assertions and updated all four in one pass.
Review folded five further corrections, two of which fix reasoning of
mine that was wrong:
- I claimed reversing `frame` and `mapping_generation` "fails to
compile" because they are different types. **False for NAMED
variant fields** --- the initializer uses names, so reordering the
declarations compiles and shifts postcard's positional bytes
silently. The pin is the only thing catching that.
- Ladder loops now track `PROTOCOL_VERSION` while TRIPWIRES stay
literal. I had flattened both to `25`. A tripwire is literal so a
bump is a conscious edit; a ladder must move, or the next bump
silently stops testing the top rung. G14b is unaffected ---
`PANEL_MAPPING_MIN_VERSION` stays literal, because there the
arithmetic is exactly the hazard.
- `assert!(24 < MIN)` was a compile-time tautology holding for every
value above 24. Replaced with the literal equality plus
`assert_ne!` against `TEXT_INPUT_MIN_VERSION`: the mapped family
must not share v24's gate, or it is admitted on sessions that
negotiated only `TextInput`.
- Statusline support loop reaches `PROTOCOL_VERSION`; public protocol
history records v25.
**CI-red observations are in the LANE LEDGER, not the registry**, and
that is deliberate: `ci-red-signatures.md` here ends at U9 while the
unmerged replay branch already added a U10, so a row from this branch
would duplicate an id or invent one blind --- which this file's own
history records going wrong, two branches' entries merging "without a
conflict, producing duplicate ids across four sites". R7 twice and the
composition budget once, fragments verified, owed to the registry by
whichever branch merges second.

First implementation commit for parent acceptance 48. The daemon-side
replay and every producer-side rule land here; the daemon-side witness
matrices (A1-A5, B1-B6, and Q#BP-R2's document->terminal row) are the
next commit and are NOT claimed yet.
**MODIFIERS NOW CROSS THE SEAM (R-a).** The daemon destructured `mods`
into `..` and the dispatcher had no parameter for them, which inverted
two behaviours rather than degrading them: `apply_terminal_gesture`
gates child reporting on `!shift`, so Shift is the user's "select
locally instead of talking to the child" override, and the document
path reads Shift to extend the selection.
**THE REPLAY IS THE SHARED PATHS, NOT NEW ONES.** A terminal panel goes
through `apply_terminal_gesture` --- "the one terminal pointer path,
shared by both frontend kinds" --- with the side window's
`TerminalViewKey` and a viewport of `rows - 1`, never the full grid: the
frame would make the mode line a child cell and put every clamp a row
out. A document panel scrolls through the window-scoped `scroll_window`
and replays selection through new window-TARGETED writers.
Those writers exist because the selection API is active-window scoped.
`Drag` and `Up` do not activate, and another frontend can interleave
between a `Down` and its tail, so a replay reading `active_window_mut()`
would act on whatever happened to be active then. `panel_cell_byte`
converts against the SIDE window's own `view_top` and fold map without
`activate_and_position`'s `set_active_window_id`. The one place the
ambient helper is used is the double-click word selection, two
statements after the `Down` activated that window synchronously, and it
says so.
**Q#BP-R2 IS ORDERED, NOT MERELY PLACED.** A terminal panel's chrome
wheel is consumed before `focus_window`, before `active_frontend`,
before any controller claim and before the shared path --- `activates`
is `!Move` for a terminal, so a check any lower would leave the wheel
changing FOCUS while scrolling nothing.
Producer half, all target-blind because `PanelFrame` carries no
target-kind field:
- a press on the band's MODE LINE neither sends nor arms. Arming
would let a drag into content emit a `Drag` with no accepted
`Down`, which no receiver-side rule can undo.
- `gesture_last_content_cell`, a TERMINATION FALLBACK distinct from
the dedupe baseline. `last_pointer_cell` is cleared on press
precisely so the first drag after a press reaches the daemon
(asserted at `main.rs:19841`); storing the press cell there would
suppress it. The new field is written on arm and on each accepted
content motion, cleared on release and on either identity change,
and `panel_motion_is_new` never consults it.
- a crossing `Drag` is normalized and then deduped; `Up` is always
sent, always at a content coordinate.
- the gesture latch now dies on a change of EITHER identity --- panel
or geometry --- and survives a same-identity repaint.
Six mutations, each biting its own row:
M-P1 arm on a chrome press -> the producer arming row
M-P2 release reads the dedupe field -> the chrome and no-motion rows
M-D1 no reset on panel epoch -> the identity row
M-D2 no reset on geometry epoch -> the identity row
M-D3 reset clears `pointer_held` only -> the identity row
M-D4 reset on every frame -> the identity row's negative leg
M-P2 caught a defect in my own witness before it caught the code: the
no-intervening-motion row called `panel_motion_is_new` BEFORE asserting
the release, which populated the very field the mutation reads, so a
conflated implementation passed. The probe now runs after the
assertion, and the row is named for a scenario it actually performs.
One existing test moved with the contract rather than against it:
`a_held_button_makes_panel_motion_a_drag_and_a_release_lands_outside`
poked `panel_motion_is_new` and expected the release to follow it. It
now drives both fields as the production motion path does; its
assertion, and the dedupe guarantee it protects, are unchanged.

The comment claimed every v6-v23 daemon decodes the variants before
`PanelPointer` on every session. False on both counts: `PanelPointer`
arrived at v21 and is gated, so a wedge before it shifts its
discriminant and breaks v21-v23 PANEL traffic --- not v6-v20, and not
every session.
The pin itself is unchanged and still fires (15 -> 16). What was wrong
was the justification, and an inflated one is not harmless: it sends the
next reader hunting a larger blast radius than exists, and it teaches
the wrong rule about which populations an insertion actually reaches.

**A1 is an exhaustive loop over all 35 function keys, not spot checks.**
The defect it closes was `_ => return None` swallowing F13 upward, and a
test covering F1-F12 would have passed against exactly that. Each row
also asserts `should_forward_key`, because translating without
forwarding leaves a key mapped and inert --- which reads as a daemon
keymap gap rather than a frontend one.
**A2 asserts both halves**: `BackTab`, and `Shift` still set. A
`BackTab` that lost its modifier is indistinguishable from one the user
did not shift. **A3** likewise pairs the mapping with forwarding.
**A4 establishes idle rather than asserting it.** A fresh `State` starts
with `dispatch_idle` false --- the daemon has not spoken yet --- so the
first version of the row asserted the precondition and failed. Had it
been written the other way round it would have tested the INTERCEPTING
case under an idle name, which is the state where Escape never quit
anyway: the row would have passed while proving nothing about the
behaviour A4 changes. It now sets idle, confirms nothing intercepts, and
asserts both halves: the Escape reaches the daemon AND no exit occurs.
**The frozen-byte pin sits on `PanelPointer`, not on `TextInput`, and
the placement is the point.** `TextInput` is appended, so its own
round-trip is byte-identical whether or not a variant was inserted
beneath it; only the PREVIOUS final variant's bytes move. Every v6-v23
daemon decodes the variants below `PanelPointer` on every session, so an
insertion anywhere earlier is a silent wire break for all of them.
MY FIRST MUTATION OF THAT PIN WAS WRONG AND THE PIN WAS RIGHT. I
inserted the wedge variant before `TextInput` --- which is to say AFTER
`PanelPointer`, exactly where an append belongs --- and the pin passed,
correctly, because nothing shifted. Re-run with the wedge BEFORE
`PanelPointer`, it fails with the discriminant visibly moving 15 -> 16.
Worth recording because a mutation that targets the wrong side of the
boundary reports the pin as vacuous when it is sound.

**The P1 was real and my previous fix only did half of it.** Arming and
completing a `TypedEditRecord` are separate steps: `typed_edit_complete`
is called from `insert_char` / `insert_char_over_region` and NOWHERE
else, so routing the single-scalar branch through the generic
`insert_text_input` left the arm holding `None`. `this_command` rotated
correctly and `buffer.after-edit` saw no record --- auto-pairing stayed
broken while the command side looked right, which is the failure mode
that hides longest.
The single-scalar branch now goes through `insert_char_over_region(ch)`,
which handles the no-region case itself by delegating to `insert_char`.
`insert_text_input` is documented as the MULTI-scalar path only, with
the trap named at the definition rather than left for the next caller
to rediscover.
**The witness consumes the record rather than inspecting
`this_command`**, per the review. `single_scalar_text_input_produces_a_consumable_typed_edit_record`
takes it through the same `pmacs.pair._last_record` seam `pair.lua`
uses, and `single_scalar_text_input_auto_pairs_like_a_keypress` states
the same fact in the terms a user would notice: typing `(` must produce
`()`. **Mutation M-1a-1 reverts the fix and both rows fail**; the four
others stay green, so they are discriminating rather than duplicated.
**A ceiling tripwire proved less than it claimed.** The discovery
acceptance looped `6..=23` and then rejected `PROTOCOL_VERSION + 1`, so
a supported set that ENDED at 23 would have passed while
`PROTOCOL_VERSION` was 24 --- the accepted half said nothing about the
version the constant names. It runs to `PROTOCOL_VERSION` now.
**The public protocol history stopped at v23 while both constants
already included 24.** The rustdoc above `PROTOCOL_VERSION` and
`SUPPORTED_PROTOCOL_VERSIONS` now carries the v24 bump, and states the
thing that makes it unlike its predecessors: **it is the first
FRONTEND->INSTANCE extension needing a gate in BOTH directions**,
because the producer withholding is not enough when a peer compiled from
this same crate can encode the variant whatever it negotiated.
Three typed-edit doc sites said the arm is set by "the dispatch fallback
only" or named two producers; there are three now, and the single-scalar
`TextInput` path is one. `typed_edit_arm`'s own doc gains the warning
that arming is only half.
Also 1a's suite: A6 (one commit, one edit, one undo unit), A7 (a prompt
accumulates scalars in order), and A9's boundary row --- a payload
exactly at the cap lands intact, the complement of the rejection that is
enforced where a test can reach it.

**A7 AND A8 WERE UNREACHABLE FROM THE REAL PRODUCER.** The intercept
branch sends a truncated `Key` and returns, and TextInput classification
sat below it --- but a modal prompt or a focused terminal is exactly
what makes `daemon_intercepts_keys` true, so the two contracts about
prompts and terminals were reachable only when neither was present. The
selection moves ABOVE the intercept return, where the producer sends the
same `TextInput` in every state and the daemon applies the modal
precedence, which is where it belongs: the frontend cannot see which
shadow is up.
Ordering against the branches below is safe by construction rather than
by luck --- `text_input_payload` returns `None` whenever a command
modifier is held, so Ctrl-V and command chords can never be shadowed.
**A pure `text_input_payload` test cannot catch this**, which is the
lesson worth keeping: the classifier was right the whole time and the
call site was wrong. The witness has to drive `intercept = true` and a
terminal.
**SINGLE-SCALAR PROVENANCE WAS PROMISED IN A COMMENT AND NOT
IMPLEMENTED.** §5 rules that a single-scalar commit is indistinguishable
from a keypress; the code only broke the chain for multi-scalar and
called a generic insert, so `this_command` went stale and no
`TypedEditRecord` was produced. Auto-pairing (Q#AP9) and every other
typed-edit consumer would have silently stopped recognizing GUI input
--- surfacing as "auto-pair stopped working in the GUI", far from its
cause. Now runs the real machinery: `rotate_command("buffer.self-insert")`
-> `typed_edit_arm(ch)` -> the one edit -> `typed_edit_finish` ->
`typed_edit_set_armed` -> `buffer.after-edit` -> clear, which is the
tail `dispatch_key` already runs.
**THE PRODUCER GATE WAS ONLY HALF THE WIRE CONTRACT.** The daemon
accepted `TextInput` from every installed session, so a peer negotiated
at v6-v23 --- compiled from this same crate, and postcard will happily
write the discriminant --- could mutate a buffer through a variant its
own session never declared. Now gated on the AUTHENTICATED session's
negotiated version.
**A4's structural half is implemented, not just its behaviour.**
`apply_keyboard` returns `()`, so `LifecycleRoute::Exit` is the sole
`EventOutcome::Exit` producer and the obsolete keyboard-exit channel is
gone rather than merely unused. The type survives, as ruled: one
producer is not one variant.
Also: `dispatch_text_input`'s rustdoc claimed a boolean return that its
signature does not have.
VERSION FALLOUT, SORTED RATHER THAN RENUMBERED.
Six deliberate tripwires took the conscious edit they exist to force
(protocol.rs, bottom-panel, discovery x2, statusline, and the vterm one
that was missing from my inventory). Two carried the version in their
NAME, so the name moved with the number rather than being left to lie.
Two ceiling assertions --- `!is_supported_protocol_version(24)` ---
now probe `PROTOCOL_VERSION + 1`, so they keep meaning "the set ends at
the current wire" instead of needing a hand-edit every bump.
`m4_6_handshake_accepts_v6_peer` was GENUINELY DEFECTIVE and is the one
real find: its name and the M4.6 contract say **v6 is the floor**, but
its body asserted `is_supported_protocol_version(PROTOCOL_VERSION)` ---
"the current wire accepts itself", a different and far weaker claim that
would have kept passing after v6 was dropped from the supported set,
which is the only regression it exists to catch. Anchored on literal 6.
The M10 pair needed no edit: they already use `PROTOCOL_VERSION`, and
they failed in the first sweep only because it predated the
`SUPPORTED_PROTOCOL_VERSIONS` fix.
`ADVERTISED_PROTOCOL_VERSION == 20` did not fire, as it must not.

The mechanism, without its witnesses yet; tests follow in the next
commits.
**A1-A3 were mapping gaps, and forwarding was half the fix.**
`translate_key` gained F1-F35, Shift+Tab -> `BackTab`, and
`ContextMenu` -> `Menu`. All three already existed in the protocol
`Key` enum and the TUI already sent them, so this closes a divergence
rather than inventing a convention. **`should_forward_key` had to learn
them too** --- translated but unforwarded, they would have mapped
correctly and still done nothing, which reads as a daemon keymap gap
rather than a frontend one. They forward with ANY modifier, like motion
keys: they are command keys that never insert text, so the
chord-withholding rule has nothing to protect them from.
F-keys are an exhaustive match, not arithmetic off `F1`: winit's
`NamedKey` is `#[non_exhaustive]` and its ordering is not a contract, so
an offset would corrupt silently the day a variant is inserted.
**A4 --- every Escape now reaches the daemon and none exits.** The
`intercept || completion_open` test went with the quit branch: it never
decided what to SEND (both arms sent the same `Escape`), only whether to
send at all, and with one behaviour left there is nothing to choose.
Both flags remain live for the OS-paste, round-trip and
completion-accept paths.
**The v24 wire variant is APPENDED and the reason is postcard.** It
encodes a variant by positional index, so widening any variant above
would re-interpret every older peer's bytes. `TextInput` carries an
untrusted `frontend_id` like its neighbours --- the daemon uses the
authenticated source --- plus the text.
**It is not `Paste`, and the difference is behavioural.** A terminal
receives it as RAW UTF-8, never bracketed (A8): a shell that sees
`ESC[200~` treats input as pasted and changes how it handles newlines
and completion. The clipboard slot is untouched, because nothing was
copied. And the document path is ONE edit (A6) --- one undo unit, one
`buffer.after-edit`, one eligible CRDT op --- which is the entire reason
the variant exists, since a two-scalar grapheme sent as two keypresses
is two undo units that a remote edit can interleave.
**A5's precedence is a pure function** (`text_input_payload`) so the
eight rules are testable without a window. A keypress stays `Key` unless
a rule moves it, and only printable MULTI-scalar moves; the version gate
WITHHOLDS rather than degrades, so a `< 24` daemon keeps exactly the
behaviour it has, truncation included.
**A7's ordering falls out of routing through the existing shadow
handlers** one scalar at a time, rather than reaching into prompt state:
history, completion and acceptance stay in one place.
THE 1-PRE EFFECT HARNESS CAUGHT A REAL DEFECT IN THIS COMMIT. Bumping
`PROTOCOL_VERSION` to 24 while leaving `SUPPORTED_PROTOCOL_VERSIONS` at
`..=23` made the handshake reject its own version. All NINE effect rows
failed while the thirteen routing rows passed --- the M21 signature,
meaning `EffectHarness::new` could not attach at all. A pure-routing
harness would have stayed green.

Review round three on PR #235, plus the diagnosis of its first CI run:
all five test legs failed on one test, deterministically, while
sixteen local cores stayed green.
The mid-walk cancellation bound could not bite the per-entry poll
alone. The cancel lands two files into a 41-file directory --- root
contributes three dir entries --- so with the per-entry poll deleted
the directory finishes and the per-DIRECTORY poll catches at seen ==
44, under the old bound of 60. The bound is now 40 against an expected
exactly-35 (3 + one 32-entry poll stride), and the entry-poll-only
bite goes red at 44. Verified both ways.
The retirement helper observed a REQUEST, not settlement: it returned
as soon as an active row showed cancel_requested, which a worker that
ignored the token and completed successfully would satisfy. It now
waits for a completed row with status == "cancelled", making the
lane's "settles cancelled" claim true at the witness, not just at the
Rust layer.
The CI red: d3_pump(1600) between the mid-walk join and the late.bbb
write assumed the held walk would complete within 1.6 s. On a 3-thread
CI pool, 8 sleeps of 1200 ms drain in ~3.6 s of waves, so the file
landed before the held walk even STARTED and folded into the joiner's
baseline --- exactly the fold the test exists to assert for mid.bbb,
applied to the wrong file. Deterministic on every 2-4-core runner,
invisible on 16 cores. The drain is now an observable condition ---
at least one post-join walk completed and none active --- with the
saturation sleeps at 800 ms, and the three saturation tests plus the
whole eighteen-test family re-run green under taskset -c 0-3, the CI
pool shape reproduced locally.
A fixed-duration pump against pool-dependent timing is a core-count
assumption in disguise; the lane records it as such.
Superseded round-one text in the lane (the fallback "unreachability"
claim round two disproved) is corrected in place.
One gate run also hit the live attach-retry BrokenPipe row --- fourth
occurrence, all three required fragments verified against the durable
sweep log, recorded in docs/ci-red-signatures.md. This lane touches no
pmacs-gpu code, no wire, and no protocol; the same sweep passed twice
earlier the same day on materially the same tree. The retirement bar
(mechanism, not rate) is unchanged.

Implements docs/lsp-file-watch-d3-framing.md revision 4, approved
2026-08-11 with the four rulings adopted as proposed: the honest bar
(absent at idle, one attributable job per concurrently due group), no
exclusions by default, server root_uri -> cwd -> attachment fallback,
and constants rather than config keys.
pmacs.fs.walk_tree: the whole recursive tree as ONE cancellable job
(JobKind::FsWalkTree, reply reuses ReplyKind::ReadDir --- identical
payload shape, so the Lua boundary needs no second conversion). Names
are base-relative; symlinks recorded, never traversed; an unreadable
subdirectory skips its subtree (scan_tree's pcall behaviour); only the
root failing to open fails the walk; the cancel token is polled once
per directory. Eight Rust unit tests, including flat-directory entry
parity with read_dir_blocking and the two review-round cancellation
cases (empty-tree pre-cancel; mid-walk via the cfg(test) entry hook).
The watcher itself is rewritten as the framed group scheduler. No
sleeps anywhere: one process.after-tick subscription (installed once
and guarded --- pmacs.hook.remove does not exist) drives every
(server, base) group's deadline off monotonic_ms, autosave's Q#AS2
idiom. The old design held one pool thread per sleeping watcher and
allocated 1 sleep + D read_dir jobs per watcher per tick --- 1,326
per tick for rust-analyzer's six watchers on this 220-directory
checkout. At idle there is now NO running job, which is also the
strongest witness in the suite: activity_summary settles to None, and
that assertion is unwritable under the old design.
The scheduler is the framing's state machine, all three review rounds
included: single-flight per group with generation-checked completions;
deadlines advanced from completion; the round-3 three-arm completion
partition (success / stale-or-retired / live non-success, with the
failure latch and quiet cancellation); joins wake the group, queue
exactly one follow-up mid-walk, and never reset the backoff curve;
per-watcher baselines --- the first snapshot whose WALK STARTED after
the join; membership captured at scan start; per-member cancellation
recheck at emit through the preserved _after_scan_for_tests seam;
backoff 250ms x2 to a 4s cap, reset by any emitted change; retirement
cancels the in-flight walk cooperatively.
Verification: eighteen acceptance tests. The six #234 tests are
byte-unchanged and green. Ten witnesses cover the framing's plan (the
review rounds added the fallback-determinism and root-boundary pair,
making twelve):
idle absence (and never a sleep purpose), one walk job per scan on a
twelve-directory fixture, join-wakes plus the registration epoch,
queued baseline for a mid-walk join (driven by saturating the worker
pool so the walk genuinely queues), single-flight under a withheld
completion pump, retirement and rebaseline through the fake's
unregister/re-register triggers, live cancel via pmacs._async._cancel
on the queued job, live failure with the once-per-error latch and the
preserved-snapshot recovery (DELETED for the pre-failure file is only
derivable from the retained snapshot), backoff shape from seam
timestamps, and the configured-root base.
Every witness was mutation-tested. Two findings from the bites:
- Retirement is DOUBLE-ENFORCED (unregister path and post-scan sweep)
and biting either copy alone is masked by the other; only biting
both goes red. Kept deliberately: the sweep covers seam-cancelled
members, the unregister path covers idle groups whose next deadline
is seconds away.
- The first idle probe was VACUOUS: it read pmacs.async instead of
pmacs._async, errored, and the unwrap_or_default made every sample
read as "absent". The probe now expects rather than defaults, so a
broken probe is a red test, not a green lie.
One environmental fact, recorded in the lane: an empty stray /tmp/.git
(since removed) made project detection root every markerless tempdir
fixture at /tmp, which under Q#D3-3 the watcher then faithfully
watched. A markerless-fixture red that looks like a watcher bug may be
an ancestor marker.
A pre-commit review round found four blockers, all fixed here:
- walk_tree checked cancellation only inside its entry loops, which an
EMPTY tree never enters --- a pre-cancelled queued walk returned an
empty SUCCESS, which the success arm would commit and diff into a
deletion storm. Cancellation is now checked before opening and
before returning, cancellation outranks a missing-root error, and a
unit test pins both.
- The neither-root-nor-cwd attachment fallback was still pairs-order
nondeterministic --- the exact accident D3 set out to remove, behind
a comment claiming otherwise. It now takes the lexicographically
smallest attachment directory. Verified at the spawn sites: every
server spawned with an attached file gets cwd = root, so the arm is
defensive and unreachable through production spawning --- which is
also why it carries no through-the-server witness.
- A base at the filesystem root joined as //path (and file:////path in
URIs). Both join sites now go through join_under, the root-aware
idiom dired's handler already uses, and the dir-of capture for a
root-level file ("" from the match) normalizes to "/".
- The walk-count and scan-times probes defaulted on error, so two
broken probes could compare equal and pass the retirement witness.
Every probe now expects --- a broken probe is a red test, the same
correction the vacuous idle probe forced.
A second pre-commit round found three more, all fixed here:
- Mid-walk cancellation was UNWITNESSED: both Rust cancel tests
pre-cancelled and the acceptance test cancelled a queued walk, so
deleting the internal polls left every test green. A cfg(test)
entry hook now flips the token at an exact entry boundary and the
witness asserts the walk stopped NEAR it (bound on entries
processed), which is what discriminates the polls from the
entry/exit checks. The retirement witness now holds a walk in
flight across the unregister and asserts the job settles cancelled.
- The "unreachable fallback" claim was WRONG: pmacs.lsp.spawn may
omit both cwd and root_uri, and ensure_server adopts such a live
server for markerless files (root_uri and key_uri both nil). The
lexicographic-minimum fallback now has a through-the-server
witness: five sibling directories, the minimum opened last ---
five, because with two the build's hash order coincided with the
lexicographic answer and the first-pairs bite survived.
- The root-boundary joins gained a witness through exported
production functions (the _deliver_status pattern): the matcher and
URI builder driven at base "/", where reverting either join_under
call makes the anchored glob refuse //hit and the URI grow a fourth
slash. No fixture can walk / for real.
Verification totals after both rounds: eight walk_tree unit tests,
eighteen acceptance tests (six byte-unchanged, twelve witnesses), all
mutation-verified.
No wire change, no PROTOCOL_VERSION bump; walk_tree is an fs binding.

Review of the #233 implementation found two correctness defects. Both
are cases where the FIRST fix for #233 was itself wrong, which is worth
naming: this lane repaired absolute globs and, in the same change, broke
a case that had worked since May.
P1 --- `resolve_watcher` returned "absolute" for EVERY string, so the
form was carried but derived from the union arm rather than from the
pattern. A bare `*.txt` is a valid relative pattern (LSP 3.17 defines
`Pattern` relative to a base path; VS Code treats string watchers as
applying across workspace folders), and classifying it absolute matched
it against `<base>/foo.txt`, which `^[^/]*%.txt$` can never match. A
leading `/` is what makes a pattern absolute. The `filewatchflat` test
could not catch this: it sends the RelativePattern OBJECT form, so it
constrains the object arm, never the string arm the regression lived in
--- the framing's own F1 finding, repeating inside the lane that named
it.
P2 --- `scan_tree` awaits `read_dir` once per directory, so the watcher
coroutine sits suspended for most of a tick with `_sleep` already
cleared. A cancel arriving there sets `cancelled` and has no sleep to
interrupt, and the resumed scan ran on to `did_change_watched_files`:
one stale batch under the superseded pattern, which is a wrong-pattern
notification the server acts on. Cancellation and liveness are rechecked
after the scan.
Both tests are mutation-checked and each bite fails only its own defect.
Reverting P1 fails the bare-string test alone --- the absolute test
still passes, so the two readings are independent. Deleting P2's recheck
reproduces the defect verbatim: `.received = "1 file:///…/foo.txt"`,
a batch from a watcher that was already cancelled.
P2's witness needs a seam. The race is a cancel landing during one of
the scan's suspensions, which no arrangement of real timing produces on
demand --- the same situation, and the same device, as `git.lua`'s
`_deliver_status`. `pmacs.lsp._after_scan_for_tests` is nil in
production and is handed the SCAN RESULT deliberately: a test that
cancels on any other scan passes with the recheck deleted, because the
loop would break at the post-sleep check and emit nothing anyway.
Gates: 9/9 green.

Implements D1 and D2 from docs/lsp-file-watcher-framing.md (revision 1,
approved 2026-08-10). The user ruled that the walking survives this
lane; D3 gets its own framing.
D1. resolve_watcher now returns (base, pattern, form) and the watch
record carries the form. Per LSP, a plain-string glob matches the
file's ABSOLUTE path while a RelativePattern's pattern is relative to
its base --- and resolve_watcher discarded the distinction, so every
downstream consumer matched relatively. Real servers send absolute
globs: rust-analyzer was never told about any file change (all six of
its globs absolute), and gopls saw go.mod but never a .go edit. The
match subject is chosen in start_file_watcher --- form "absolute"
matches base .. "/" .. rel, form "relative" matches rel unchanged.
scan_tree still walks in relative terms; only the string handed to the
matcher changes.
D2. register_file_watchers now cancels the outgoing record list before
file_watchers[skey][reg.id] = recs drops the only reference to it. The
cancel loop is factored into cancel_watch_records, shared with
unregister_file_watchers, so the two paths cannot diverge.
rust-analyzer registers the same id twice with no unregister between
--- previously 12 concurrent pollers, 6 permanently uncancellable.
Verification, per the framing's plan. Three new fake-LSP modes and
tests beside m4_24, each mutation-tested against the defect it names:
- filewatchabs registers a plain-string absolute glob whose relative
reading matches nothing. Red before D1 (reverting the match subject
fails exactly this test), green after.
- filewatchflat registers a RelativePattern without a leading **/
(*.txt at the base) --- F2's guard. Matching every form absolutely
fails exactly this test, so the obvious wrong fix cannot land green.
It also pins that a base-level pattern does not match into
subdirectories.
- filewatchrereg registers the same id twice (rust-analyzer's shape).
The witness is observable polling, not table shape: f.old exists on
disk before either .new event lands, so a leaked watcher at the same
250ms cadence reports it before the second positive. Reverting D2
fails exactly this test, the leaked .old event visible in .received.
m4_24 stayed green under all three mutations --- the framing's F1
finding (the existing test is insensitive to D1 in both directions),
confirmed rather than assumed. It is kept unchanged.
The framing doc records the approval and the answered ruling; the
active-work lane moves to IMPLEMENTED with the verification results.

Merged rather than rebased, for the reason #231 was: nineteen commits
replayed against a ledger four lanes had rewritten is nineteen chances
to lose a lane entry, and the reviewed commits keep their SHAs. One
file conflicted.
The conflict was diff3-style with an EMPTY base --- both sides added
lanes at the same offset --- so it resolved by keeping both, this
branch's #227 lane ahead of main's. Worth noting because an empty base
section is exactly what produced the stray `|||||||` markers found
committed in this file earlier today: the base half of a diff3 conflict
reads as content if it is resolved by hand in a hurry.
This unblocks the lane. `pmacs.window.capture_destination` now exists
on the branch (`src/lua_bindings/window_panel.rs:638`), which is what
#227's review found missing and what #231 was split out to provide.

Merged rather than rebased. Eighteen commits replayed against a ledger
that three other lanes had rewritten meant eighteen conflict
resolutions in `docs/active-work.md`, each one a chance to lose a lane
entry; merging resolves it once, against the state that actually ships,
and leaves the reviewed commits' SHAs intact. Only one file conflicted.
`docs/ci-red-signatures.md` auto-merged **without a conflict** — the
same silent path that produced duplicate U4/U5 ids when #232 rebased.
Verified by hand afterwards: ids U1-U8 are disjoint. They are out of
numeric order (U6/U7 sit ahead of U4/U5) and are left that way rather
than moved, since the note at the U6 row explains the history and
relocating sixty lines inside a merge commit hides real changes.
Three leftover conflict markers were sitting in `docs/active-work.md`
on `main`, committed by an earlier lane's resolution. `git diff --check`
flags them — but only for a working-tree diff, which is why the gate's
`diff-check` step never saw them and they survived several merges.
Removed here.
The U4 row is corrected on evidence this lane produced:
- **Flavour was wrong as a matching key.** The row was filed from
#229's `lua54` red and put the flavour in the key; #231 reddened the
identical selector with the identical three fragments twice on
`luajit`. Matching as filed would have missed both.
- **A fourth sighting was a deliberate bite, not an occurrence** — the
defect reintroduced on purpose during the test's own development. It
is recorded for what it proves instead: the genuine defect and these
CI reds are signature-indistinguishable, same message class and same
full-timeout duration.
- **The control experiment is written down with its own bounds** — five
green base observations against 0/2, 4.8% under an equal-rate model,
and the two facts that bound it: attempt 5 reddened a different
selector, and the branch side was never resampled.

`required_purpose`'s invalid-UTF-8 refusal told the caller that their
process purpose "is displayed to the user in *workers* and in the
modeline". Neither is a process surface. Stage 1 deliberately keeps
processes out of `*workers*` — which lists async JOBS — and out of the
statusline activity indicator; a process's purpose is exposed through
`pmacs.process.list` and nowhere else, and joining the two planes is
Stage 2's work (framing §3, Q#W-4).
The refusal is correct and stays: a purpose that cannot be displayed
anywhere should still be refused, and nothing spawns either way. What
was wrong is the reason given to the user, which pointed them at two
places their process will never appear. A diagnostic that misdescribes
the system is worse than a terse one, because it sends the reader
looking in the wrong place.
The job-side twin diverges rather than converging. `_push_dispatch_name`
refuses a non-UTF-8 handler name for the same reason, and there
`*workers*` and the modeline are the RIGHT answer — the name is composed
into every job's purpose and a job renders in both. It said only "as
part of every job's purpose", which names no surface at all, so it now
names the two it reaches. The two messages must not collapse into one
sentence: whichever wording won would be wrong on the other side.
Verification. `the_two_utf8_refusals_each_name_the_surface_their_own_text_reaches`
asserts both directions, positive AND negative — the process message
contains `pmacs.process.list` and NOT `*workers*`/`modeline`, the job
message contains both of those and NOT `pmacs.process.list`. The
negative halves are the anti-collapse guard; without them a later
"unify the wording" edit reintroduces exactly one wrong sentence and
passes every other test in the file. The existing row-table assertion in
`spawning_without_a_real_purpose_is_refused_and_starts_nothing` now runs
as far as the surface name too, so the same edit breaks two tests.
Three mutation checks, each red on its own claim: restoring the old
process wording fails both content assertions; collapsing the job
message onto the process wording fails only the new test (which is the
point — the old job test asserted the prefix alone and could not see
it); restoring the job message's original vague wording fails it too.
The doc comments were fixed with the literals. `required_purpose`'s
rustdoc now states which surface its message names and why it names
neither of the other two, and the `_push_dispatch_name` comment states
the converse. A corrected string whose doc comment still argues the
other way is one refactor from reverting itself.

Review round 2, findings P2a and P2b, plus P3's stale recovery
summaries. Three defects, and the fix is deliberately different in each
place because the constraint is.
## P2a — invalid UTF-8 bypassed the `purpose` diagnostic
`required_purpose` read the field with `value.to_str()?`. Lua strings
are BYTE strings, so `purpose = string.char(255)` is a value a caller
can write, and `?` surfaced mlua's generic conversion error BEFORE this
lane's own diagnostic was ever constructed: the caller was told neither
the field nor the rule.
**This is the third time this project has hit the class** — an unowned
Lua string converted with `?` ahead of the owned message; the
destination-capture lane corrected the same shape two rounds ago. It
refused before spawning and nothing leaked, so the defect was the
message, not the outcome. The conversion failure is now mapped onto
this function's own message, and the new acceptance row asserts on
message CONTENT so retyping the read as a bare `?` breaks the test
rather than silently degrading the error.
Auditing the rest of the lane's diff for the same class turned up
exactly one more: `_push_dispatch_name` took `name: String`, so a
registered handler name that was not valid UTF-8 failed at first
dispatch with mlua's generic message. It now takes `mlua::String` and
maps that failure onto an owned diagnostic naming the argument and the
rule. Those are the only two Lua-string reads this lane added; every
other binding it adds takes `()`.
## P2b — no safe display-text boundary. Two halves, two different fixes
### Handler names are refused at the source
`pmacs.workers.register` type-checked its name and nothing more, which
was defensible while the name died inside `dispatch`. It no longer dies
there: the ambient carries it into every job the handler allocates and
composes it into `purpose`, which `*workers*` and the modeline both
render. So it now gets `purpose`'s meaningful-value standard —
non-empty, not whitespace-only — plus control characters, which have no
legitimate place in a registered identifier.
### Purposes are ESCAPED at presentation, not rejected at the registry
A purpose may legitimately contain a newline: a filesystem path can, and
`pmacs-magit`'s spawn purpose is a whole argv. **This is the shape of
the `#228` decision, and it is consistent with it** — the one-line
constraint belongs to the surface that has it, not to the registry that
does not. There, `Command.description` stays free-form and the two
single-row consumers clip with `description_first_line`. Here the
equivalent is escaping rather than clipping, because a purpose's later
words are load-bearing: an argv's second word says which file, and a
clip would drop it silently.
`purpose_for_one_row` states the property it exists for: **a row must
not be able to forge another row.** It escapes `\n`, `\r`, `\t` and the
rest of the Unicode `Cc` class (which covers ESC, so a purpose cannot
open a terminal escape sequence either), borrows unchanged when there is
nothing to escape — making byte-identity structural rather than
asserted — and deliberately does NOT escape backslashes: no number of
them produces a second row, and doubling them would cost byte-identity
for ordinary text.
Two surfaces call it: the `*workers*` rows, and `ActivitySummary`, which
exists for one consumer that has exactly one row.
`pmacs.workers.snapshot()` is this lane's `describe-command` and stays
raw, which is what makes this a rendering decision rather than data
loss — asserted, not assumed.
## P3 — two stale recovery summaries
`docs/worker-identity-framing.md` still said "Implementation may
proceed"; it is implemented. `docs/active-work.md` still said Stage 1
takes the "first two" of owner/purpose/parent — `owner` was REMOVED in
revision 2, so it takes one of the three, and the claim the whole
`owner` argument overturned was still standing in the volatile state of
record. Both fixed section-locally.
## Verification
`tests/worker_identity_acceptance.rs`, 18 -> 24 tests:
* invalid-UTF-8 purpose refused by THIS lane's message, asserted on
content, alongside the absent / empty / whitespace / wrong-type /
metatable rows;
* a whitespace-only handler name and a control-character one are each
refused AT `register`, asserted on the error and on the handler not
being installed (dispatch reports `unknown handler`);
* a non-UTF-8 handler name is refused before the handler runs, with the
dispatch-name stack left empty;
* a purpose containing a newline renders as ONE row in `*workers*` and
as one line in the modeline — through the real rendering path, the
latter through a painted frame as well as the evaluator;
* **a purpose crafted to look like a row boundary does not produce a
second row** — asserted by counting rows, with the escaped text
asserted present so a renderer that dropped the purpose entirely could
not pass;
* a purpose with no control characters is byte-identical on both
surfaces, fixtured with a literal backslash, a literal `\v`, quotes
and a non-ASCII character.
Mutation-checked, seven guards, each failing its own test and no other:
the purpose UTF-8 diagnostic; the `_push_dispatch_name` one; the
register whitespace guard; the register control-character guard; the
`*workers*` call site; the `ActivitySummary` call site; and
`purpose_for_one_row` itself neutered to the identity, which fails both
surfaces' tests and nothing else.

Review round 1 on worker identity Stage 1. The lane shipped `purpose` as
a required field on `ProcessSpec` but made it OPTIONAL at the
`pmacs.process.spawn` Lua surface, defaulting to `label`.
**That preserved compatibility and delivered nothing.** `COHERENCE.md`
§9's complaint about `ProcessSpec` is precisely that `label` is
"caller-supplied, unvalidated convention" — so a purpose defaulting to
the label hands every existing caller back the exact convention this lane
exists to replace. The approved framing said required; this makes it
required where callers actually are.
The two fields answer different questions and neither substitutes for the
other. `label` IDENTIFIES — `lsp:rust-analyzer`, a terminal's buffer
name — so two processes running the same binary can be told apart.
`purpose` DESCRIBES: it answers "what is happening", which is what §3's
promise of visible asynchronous work is about, and which a label chosen
for uniqueness routinely does not answer.
**The refusal covers five shapes, not one.** Absent; empty;
whitespace-only; wrong type; and metatable-provided. The middle two
matter because they satisfy the type and defeat the point exactly as
copying the label across would — R42 already rejects whitespace-only
`description`s in the config registry for the same reason, and a required
field that accepts `""` is not required in any sense a reader benefits
from. The read is RAW, matching the posture `stdin` and `group` already
document in the same function: a spec table is plain data, so `__index`
cannot smuggle a purpose in.
Every refusal also asserts **the process list is unchanged**. A
validation that rejects after spawning has already done the thing it was
rejecting.
**This is a BREAKING CHANGE to a public Lua API, taken deliberately and
now rather than later.** Weighed and reported rather than decided
silently: §10 grades extension trust "missing (one class)" and P7 package
lifecycle has not started, so the third-party population calling this
binding is ~zero and the cost of the change only rises from here. Checked
for a reason that would be wrong and found none — `pmacs.process.spawn`
has no API-reference documentation and no stability promise anywhere in
`docs/`; the guide's only mentions are an audit-rule classification and a
pointer to the bundled REPL, and its semver language governs *packages'*
own versioning, not pmacs's Lua surface. `lua_to_spec` has exactly one
caller, so the blast radius is this one binding.
Eleven executable call sites updated, each with a real description rather
than the label copied across — copying it would satisfy the type and
defeat the point as surely as the default did:
builtin/packages/repl/init.lua "interactive <interpreter> session"
builtin/runtime/compile.lua "compiling: <cmdline>"
builtin/runtime/lean.lua "checking the Lean toolchain version…"
tests/fixtures/pmacs-magit/status.lua the full argv, not just the
subcommand the label carries — "git
log" and "git log --oneline -20" are
one label and different work
tests/compile_mode_acceptance.rs (4), tests/m4_acceptance.rs (1),
tests/worker_identity_acceptance.rs (2)
`lean.lua`'s site is the clearest case for the field: its comment said
the label was where "a user wondering why their editor touched `lake`
finds an owner" — one string doing identity AND explanation, which is the
conflation being undone. The label stays a key; the purpose is now the
sentence.
Two references are deliberately NOT updated: `src/audit/mod.rs` and
`tests/m7_9_acceptance.rs` contain `pmacs.process.spawn("ls")` as **audit
fixture source text**. It is lexed by the audit engine, never executed,
and editing it would change what those rule tests scan.
`required_purpose` is extracted rather than inlined because inlining it
pushed `lua_to_spec` past the 100-line clippy bound — the validation has
its own rules and its own rationale, so it gets its own function instead
of an `#[allow]`.

`COHERENCE.md` §9 grades the worker model "mechanism without identity",
and §0 names step 11 (background-work ownership) as one of the two
remaining thin ends of the golden journey. The mechanism half is solid —
cancellation, supersession, streaming, frame-aware draining, `*workers*`.
The identity half was absent: `PendingJob` carried no description of what
it was doing, `pmacs.workers.dispatch` discarded the registered handler
name three layers above anything that takes one, and §9's "no progress
indicator exists anywhere" was checkable and true.
Framing: `docs/worker-identity-framing.md` (revision 4, approved).
What lands:
**A required `purpose`, on the job and on the process.** Non-optional,
with no `Default`, so the compiler — not a test — is what proves every
dispatcher supplied one. `allocate` / `allocate_with_resource` collapse
into ONE private `JobSpec`-taking funnel (Q#W-1): the two-function split
existed only because one prior lane needed one extra parameter, and a
second lane doing the same produces `allocate_with_resource_and_identity`.
`register_external` gains a `purpose` parameter rather than deriving one,
because its `JobKind` is `McpRequest`/`LspRequest` for every method — a
category, not a description.
**A dispatch-name ambient (Q#W-2), read at that same single funnel.** The
capture point is Rust, not the Lua wrapper layer, because a handler
reaching straight for `pmacs._async._dispatch_*` bypasses the wrappers
entirely — and those are precisely the callers attribution exists for.
Seven rules; the ones that decide whether it is honest:
- **Rule 1 — the extent is NON-YIELDABLE, and that is ENFORCED.** Both
supported yield APIs refuse inside it, modelled on the `commit_to`
refusal already in `async.lua`. The guards reject BEFORE parking and
reject UNCONDITIONALLY: one placed after `_is_complete` would fire only
when a yield really occurred, passing under test and failing
intermittently in production.
- **A raw `coroutine.yield` is NOT covered, and nothing here claims it
is.** R46 is a convention, and the scheduler inspects the yielded value
only after `coroutine.resume` returns — by which point the coroutine has
already suspended — so no refusal sited in a yield helper is ever
consulted. The residual is recorded in the framing §2 and in the
suite's module docs rather than papered over with a test that would
imply coverage this design lacks.
- **Rule 5 — unwind-safe.** A raising handler still pops. A version that
did not would let one failure poison every later dispatch in the session
with a stale name: the feature would stop failing loudly and start lying
silently. The bracketing also has to preserve the tail call it replaced:
`dispatch` was `return handler(args, opts)` and propagated EVERY return
value, so the pop/rethrow runs behind a varargs boundary rather than a
`local ok, result = pcall(...)` that would silently truncate a
multi-value handler. Varargs rather than `table.pack`, because that is
Lua 5.2 surface and LuaJIT is this project's default backend.
- **Rule 6 — compose, do not replace.** `"<name>: <purpose>"`, because
letting the dispatcher's purpose win loses the third party again and
letting the name win discards the only description of the actual work.
**A statusline activity indicator** — the fourth `pmacs.statusline.register`
adopter, after `mode`, `terminal` and `lsp`. A count plus the OLDEST
in-flight job's purpose ("busiest" is not a defined quantity; jobs carry
no cost estimate), and **absent entirely** when idle rather than a
zero-width segment that costs modeline width forever to say nothing is
happening. Gated by one setting, `ui.activity-indicator` (boolean, default
true, Q#W-6) — a permanently-visible modeline element is a preference
someone genuinely holds on day one. No setting for purpose capture
itself: that is substrate.
**NO WIRE CHANGE.** The indicator rides the existing `StatuslineSegments`
vector, so a fourth provider adds an element, not a variant.
`PROTOCOL_VERSION` and `ADVERTISED_PROTOCOL_VERSION` are untouched — which
is the property that lets this run beside the two lanes holding the bump
slot.
**Q#W-7 — a pre-existing defect, repaired here, and NOT one anybody has
observed.** `Handle:await()` refuses inside `pmacs.window.commit_to`
precisely so a coroutine cannot park with the frontend scope pushed
(Journey Stage 1a, Q#JR14b). But `pmacs.async.yield_to_next_tick()` also
yields, is public, and carried no such refusal — so that invariant had a
second entrance, and a coroutine could produce exactly the misrouting the
`await` guard exists to prevent. It gains both refusals here: the same
supported yield helper, the same invariant, the same edit family, so
splitting it would have preserved a known hole without reducing
integration risk.
**Reachability by a real caller is UNPROVEN.** This was found by reading
the guard family while scouting rule 1, not by reproducing a fault. No
production caller is known to yield through that door inside a commit,
and the test pins the guard rather than reproducing a user-visible bug.
Nobody should later cite this commit as evidence the bug was observed in
the wild. Its witness is a PAIR, like rule 1's: the refusal fires **and**
the commit scope is restored afterwards — a guard that raises while
leaving the scope pushed converts a silent fault into a loud one and
fixes neither.
`journey_acceptance` carries the established `commit_to` pins —
forged-destination refusal, scope-and-restore on normal return and on
raise, the await refusal, delivery to the requesting frontend. It passes
**untouched**, which is what says this closed a gap in Journey Stage 1a's
semantics rather than altering them.
What is deliberately NOT here, and why it is worth saying:
- **No `owner`, in any spelling** — not `origin`, not `subsystem` (§3).
Populated from static per-subsystem constants it would be an origin,
not an owner, and would confidently misattribute third-party work to a
builtin at exactly the point §9 wants attribution. A field that asserts
a falsehood is worse than an absent one. The slot stays empty until P3
can fill it with a real package signal.
- **No `parent`** (Q#W-5). An unpopulated field renders as `None`
everywhere and reads as "this job has no parent" rather than "this
system does not track parents". Stage 3 builds the lifetime model and
the field together.
Consequences worth recording:
- `ProcessSpec::new` takes a third argument. The 40-odd call sites are
almost all tests; the three production ones (LSP, MCP, terminal) supply
real descriptions. `pmacs.process.spawn`'s Lua surface keeps `purpose`
OPTIONAL, falling back to the label — requiring it there would break
every existing caller for no coverage the compiler is not already
providing, and a caller's own label is not a fabrication.
- `pmacs.process.list` gains a `purpose` KEY on each row and enumerates
exactly the same processes (Q#W-4). Terminal PTYs stay hidden: three
acceptance suites use `#pmacs.process.list()` as a leak baseline, and
widening the accessor would inflate all three. Stage 2's unified view
owns that decision.
- `statusline_segments_acceptance`'s builtin-provider inventory grows to
`["activity", "mode", "terminal", "lsp"]`. That assertion exists to
grow when a builtin provider is added.

Revision 8 refuses, inside a "panel" commit_to, the mutations that
would make its relaxed preflight wrong. A nested commit_to REPLACED
the enclosing contract with its own and restored it afterwards, so
the outer restriction went out of force for the whole inner body:
commit_to(outer, function() -- "panel", relaxed preflight
commit_to(inner, function() -- "document", MASKS the outer
set_params(panel(), { dedicated = true }) -- ...and succeeds
end)
display(result, { side = "bottom" }) -- ...which now FALLS BACK
end, "panel")
Every step is legal on its own, and the outer commit then overwrote
a newer document buffer --- the P1a failure the lane exists to
remove, reached through one extra call.
What this invalidated, precisely: NOT the enumeration of dedication
write sites. Every site in it is real and still guarded. What was
wrong was the claim that the guard was in force for the whole outer
body. So the enumeration is inherited and qualified, not redone.
Contracts now COMPOSE rather than replace. The core holds a stack;
ScopedFrontendGuard pushes on entry and truncates back to its own
depth on every exit path; panel_commit_dedication_refusal consults
every contract in force rather than the innermost. The strictest
active restriction wins. Matching stays per frontend --- a nested
commit for a different frontend may dedicate its own side slot,
which cannot change where this frontend's side request lands.
Nesting itself is NOT forbidden, which was the other candidate fix.
It closes the hole by prohibiting a construction no rule objects to:
commit_to is public Lua API for saying where a continuation's result
belongs, and a body committing to a second destination (a diff
beside a status panel) is where #227's adoption is heading. Only the
restriction needed preserving. Detecting the dedication when the
outer commit resumed was not available either --- that is a late
refusal, which is what revision 7 was rejected for.
Two pins, and they are a pair rather than one test written twice:
* a_nested_commit_cannot_mask_an_outer_panel_restriction drives the
same four write-site rows through a nested, entirely valid
"document" commit, and asserts the attempt is refused, the slot is
still undedicated, and the outer commit's destination is intact.
* an_ordinary_nested_commit_still_runs_and_restores_the_outer_restriction
pins that nesting without dedication is accepted, that the
enclosing restriction is back in force once the nested commit
returns, and that outside every commit dedication is ordinary
again.
Mutation-checked: restoring the guard to the innermost contract
(.last(), exactly revision 8's swapped slot) fails only the first of
those. The other 13 pins, journey_acceptance (31), dired_acceptance
(47) and cargo test --lib (1920) all stay green. The ordinary-nesting
pin deliberately survives it --- it exists to fail the other
candidate fix.
Also sweeps the comments left by revision 7, which revision 8
superseded: no fallback_commit_refusal symbol remains, but six doc
sites still described placement-boundary enforcement as the
guarantee (ViewDestination, CommitProfile::Panel, CommitContract,
capture_view_destination, commit_destination_refusal,
panel_placement_can_fall_back), plus two comment blocks in the
commit_to binding and one stale mutation note in the acceptance
suite. Net rustdoc warnings down three.
Framing to revision 9; the active-work lane entry updated in place.

Revision 8 of `docs/destination-capture-framing.md`, replacing the
revision-7 design at `ca72461`, plus the invalid-UTF-8 profile hole.
The framing now carries §3's enumeration, performed.
THE BLOCKER, unchanged. The `"panel"` commit profile skips preflight
checks 2-4 on the claim that a panel result never touches a document
window. Panel placement FALLS BACK into an ordinary document window
when the frontend is not `panel_capable` or its one side slot is
dedicated elsewhere, and installs the result there --- so a `"panel"`
commit could replace a NEWER document with every stale-intent guard
skipped.
TWO REJECTED SHAPES, kept in the framing as the record of why not
those. Revision 6 predicted the fallback at preflight and argued the
body could not change it; false, because refusing `await` stops another
COROUTINE interleaving, not the body's own synchronous statements.
Revision 7 (`ca72461`) moved enforcement to the placement boundary;
that breaks the invariant `commit_to` exists for --- `docs/agent-handoff.md`
requires it to preflight BEFORE the callback, because a body creates
buffers, handles and paint long before it asks to display anything, so
"validating at display time is four mutations too late". A refusal
arriving after all of that is a partial commit with an error return.
REVISION 8 DOES NEITHER. The preflight stays exactly where it was, and
the mutations that would invalidate it are REFUSED AT THE ATTEMPT ---
the same shape as `Handle:await` being refused inside a commit scope,
for the identical reason: something that would invalidate the scope's
guarantee is rejected outright rather than predicted around or caught
late. With them refused, the fallback never comes into existence.
THE ENUMERATION, PERFORMED --- this is the load-bearing part, and it is
closed for a structural reason rather than because inspection ran out
of ideas. Full working in the framing §3.
`resolve_placement` reaches `Ordinary` from a side request through
exactly two branches, so only two pieces of state are levers at all:
`panel_capable`, and the one side window's `dedicated`.
`panel_capable` is UNREACHABLE from a body: written only where a
`FrontendView` is constructed, and nothing in `src/lua_bindings/`
constructs, registers or unregisters one --- `register_frontend_view`
has callers only in `daemon.rs` and core unit tests.
`dedicated` has eight writes. Five are reachable: `apply_placement`'s
`Side` created, replacing and non-replacing arms, and `set_params`. Two
`Ordinary` arms are harmless --- every `Ordinary` target is filtered
`!is_side`, and one only ever clears the flag. One is a unit test.
Closing the side window is NOT a route, checked rather than assumed:
with no side leaf `side_window_for` returns `None` and placement
CREATES a fresh panel instead of falling back. `panel_hidden` is not
consulted by placement, and `params.side` is unreachable.
`quit_window`'s `QuitAction::Restore { dedicated: true }` is
UNREACHABLE, and this was the surprise --- it looked like a route with
no `dedicated` argument at the call site at all. `Restore` is stored
only on a REPLACING side placement, and a dedicated slot can never be
the target of one: a side request with a different buffer falls through
to `Ordinary`, and an exact-target request is refused by
`window_accepts_buffer`. Guarded anyway, labelled defensive, because
its unreachability is emergent from two rules in another function.
GUARDS SITED WHERE THE PROPERTY CONVERGES. All three `Side` arms are
reached through `apply_placement`, which has EXACTLY ONE caller --- so
one guard in `display_buffer` covers every request-driven dedication,
including spellings that do not exist yet. `set_params` is a genuinely
separate write and is guarded separately; dedication does NOT converge
before the field itself, and that is stated rather than papered over.
`Window::params.dedicated` is a public field, so the compiler does not
enforce the funnel --- the acceptance rows are what would catch a new
direct writer.
WHAT IS DELIBERATELY NOT REFUSED. The document profile is untouched:
constraining its body would newly refuse dired's own documented panel
path, a preservation-suite stop signal. Dedicating a DOCUMENT window is
still allowed, since it cannot change which of panel-or-document a side
request resolves to. And falling back is still allowed --- a frontend
that cannot render a panel degrades gracefully exactly as today,
because this refuses the mutation that MANUFACTURES a fallback, never
the fallback itself.
THE SECOND HOLE. `commit_profile` did `name.to_str()?`, but Lua strings
are BYTE strings, so `string.char(255)` hit mlua's generic UTF-8 error
before `BAD_COMMIT_PROFILE` was constructed --- the same reachability
class as the `Option<String>` defect revision 5 fixed, one layer down.
Bytes now, with the row asserting on message content.
TESTS: 12 pins. The inside-the-body test is ONE ROW PER REACHABLE WRITE
SITE, not per call spelling, because one spelling reaches three
different writes: `set_params`, and `display{side, dedicated}` in each
of the created, replacing and non-replacing arms. Each asserts the
three things revision 8 requires --- the dedication call is refused, the
slot is still undedicated afterwards, and nothing partial was installed
(no `*result*` buffer, panel unchanged, document unchanged).
Mutation-checked per guard: deleting the `display_buffer` guard fails
all three display rows, verified INDIVIDUALLY by rotating each to the
front so the first failure cannot mask the rest; deleting the
`set_params` guard fails only that row.
THREE FRAMING CORRECTIONS ride along, all of them cases of the document
teaching something it later argues against. Section 3 stated the
disproved premise unconditionally --- "the panel case would inherit a
check about a window it never touches" --- a hundred lines before
correcting it, so a reader met the wrong claim first; it is now
qualified at the point of the claim, and section 2 carried the same
unconditional form one section earlier ("it lands in the bottom panel")
and now says it REQUESTS one. The handoff citation was written "section
748" twice when it is LINE 748, and this document's authority is that
its citations can be followed. And the "not asserted exhaustive" hedge
on the route list is retired: the enumeration is closed structurally,
because `resolve_placement` reaches `Ordinary` from a side request
through exactly two branches.
`journey_acceptance` (47) and `dired_acceptance` (31) pass UNCHANGED.

Revision 7 of `docs/destination-capture-framing.md`, closing the
correctness blocker review found in `0efc8c0` and the smaller
reachability hole beside it.
THE BLOCKER. The `"panel"` commit profile skipped preflight checks 2-4
on the claim that a panel result never touches a document window. That
claim is false: panel placement FALLS BACK to an ordinary document
window when the frontend is not `panel_capable` or its one side slot is
dedicated elsewhere -- `apply_placement` says so in its own comment --
and then installs the result there. So a `"panel"` commit could replace
a NEWER document with every stale-intent guard skipped: capture A, the
user opens B, the continuation lands, B is gone. That is the exact
failure `commit_to` exists to prevent, reached through the profile
meant to be the safe one.
WHY NOT A PREFLIGHT PREDICTION. Revision 6 proposed predicting the
fallback at preflight, arguing nothing could change in between because
the body cannot `await`. Refusing `await` prevents another COROUTINE
interleaving; it places no restriction on the body itself, which is
arbitrary Lua running synchronously and can invalidate the snapshot in
two statements -- take the panel, set it `dedicated`, then request a
side display. No preflight predicate closes that, however phrased: the
measurement is taken before the thing it measures is decided.
WHAT THIS DOES INSTEAD. `EditorCore::display_buffer` refuses between
`resolve_placement` and `apply_placement` when a side request resolved
to `PlacementKind::Ordinary` under an active `"panel"` contract whose
destination fails the document preconditions. That is the first moment
the fallback is a fact rather than a guess, and refusing before
`apply_placement` means a refused fallback mutates nothing. The
contract rides on the core, installed and restored by the same
`ScopedFrontendGuard` that scopes the frontend, so a profile can never
outlive the body that declared it; the field is crate-private, so Lua
cannot claim a profile for a placement it did not commit to.
The preflight predicate SURVIVES as an early refusal and not as the
guarantee. `panel_placement_can_fall_back` still gates the relaxation
in `commit_destination_refusal`, so the statically knowable case -- a
frontend that cannot render a panel at all, and will not acquire the
capability mid-body -- refuses before the body allocates a buffer,
registers a handle and paints. That is the same reason `commit_to`
preflights at all. Both layers are pinned, and neither pin subsumes the
other.
The four document checks now live once, in
`EditorCore::document_destination_refusal`: they are evaluated from two
sites, and two hand-written copies is how a backstop ends up weaker
than the thing it backs.
THREE DELIBERATE LIMITS, each a different decision rather than a
stricter version of this one. The document profile is untouched --
re-running its checks at placement would newly refuse dired's own
documented panel path, which is a preservation-suite stop signal. Only
a fallback is guarded, not every `Ordinary` placement -- a `"panel"`
body calling `display_file` is pinned as succeeding. And the refusal is
of the PLACEMENT, not of falling back: a `"panel"` commit with an
intact destination still degrades gracefully into the document window,
because turning graceful degradation into an error would regress every
consumer that works today on a frontend without panel capability.
THE SECOND HOLE. `commit_profile` did `name.to_str()?`, but Lua strings
are BYTE strings, so a `string.char(255)` profile hit mlua's generic
UTF-8 conversion error before `BAD_COMMIT_PROFILE` was ever
constructed -- the same reachability class as the `Option<String>`
defect revision 5 fixed, one layer down. The comparison is on bytes
now, and the invalid-UTF-8 row joins the number/table/boolean rows
asserting on message content.
FOUR DOC SITES repeated the false claim (`ViewDestination`'s own doc
twice, `capture_view_destination`, `ViewDestinationLua`) and are
corrected. Nothing else relied on it: dired, the only Lua `commit_to`
consumer, takes the two-argument document profile and already had all
four checks; `compile.lua`'s `already_in_panel` queries live state; and
the terminal adopter's rollback keys off `created_side`, already false
on a fallback.
Tests: 12 pins, up from 8. Three carry the enforcement split and none
subsumes another -- the pre-established fallback (both causes, the body
must not run), the inside-the-body transition (the body runs, the
result must not land), and the graceful fallback (a valid destination
still lands). Mutation-checked four ways; the pattern of which rows
survive each mutation is in `docs/active-work.md`.
`journey_acceptance` (47) and `dired_acceptance` (31) pass UNCHANGED.

Section-local edit to the lane's own block; several lanes edit this file
concurrently.
Records the two commits, the green gate line (both preservation suites
unchanged), the mutation checks that show a matrix of deliberate
omissions is not passing vacuously, and the two places the framing did
not match the tree:
- the rename was 11 references across 5 files, not 8 across 4 —
`src/daemon.rs` also calls the capture;
- Q#DC-4's "frontend with no document window" is a DEFENSIVE branch.
Q#BP6 asserts a layout always keeps a non-side window, with a
`debug_assert!` in `non_side_target` that fires under `cargo test`, so
a registered frontend in a healthy editor always has a live document
window. The decision stands, but #227 should not expect to meet that
refusal.
Neither changed a decision, and both are recorded rather than quietly
absorbed: the framing says "counted, not estimated", and the next reader
will check.
`ViewDestination`'s own doc comment is corrected in the same commit,
because it repeated the framing's over-claim ("a frontend showing only a
side window") in the one place a reader would trust it, and
`capture_view_destination` now says how reachable its empty pair
actually is. Code, not only ledger, since the ledger is not what someone
reads when they wonder whether that branch can fire.

Journey Stage 1a built `pmacs.window.commit_to` for the continuation
boundary --- "the listing settles a tick or more later, and by then the
ambient frontend, selected window, and active buffer may all name
something else" --- but nothing outside the `path.open-directory`
dispatch could mint a destination to hand it. Every other async Lua
continuation therefore resolved its target from ambient state a tick
after the request, which is PR #227's P1a finding: run `git.status` in
frontend A, let B become active, and A's panel opens in B.
This is the prerequisite lane #227 blocks on
(`docs/destination-capture-framing.md`, revision 5). No adopter here:
git's adoption is #227's work, since a prerequisite that converts its
own first consumer cannot be reviewed separately from it.
Three parts.
**`pmacs.window.capture_destination()`** returns the same
nonconstructible userdata for the current frontend. No arguments, and
that is load-bearing rather than minimal (Q#DC-1): a Lua-supplied
frontend id would reintroduce exactly the fabrication hole the userdata
design closes. Profile-blind for the same kind of reason (Q#DC-4) ---
capture freezes what is true now, and what a commit depends on is
declared later, at the commit.
**`DirectoryDestination` -> `ViewDestination`**, with the Lua userdata
and the capture renamed to match. The captured triple was already
generic; only its name and its capture site were not. The document pair
is now `Option`, set and cleared together, so a frontend with no live
document window still captures rather than returning nothing and
sending the caller back to the ambient state this exists to replace.
**`commit_to(dest, body [, profile])`** (Q#DC-2/Q#DC-5), a closed set of
two. The document profile keeps all four preflight checks. The panel
profile keeps only the first --- the requesting frontend still has a
layout --- because a panel result does not occupy the captured document
window, does not replace its buffer, and does not need it to exist, so
each of the other three would refuse for a reason unrelated to what the
continuation does. Omitting the profile means `"document"`, which is
what makes the preservation promise contractual rather than careful:
every existing two-argument caller keeps all four checks by definition
of the signature.
The profile argument is typed `mlua::Value`, NOT `Option<String>`, so
its error is REACHABLE: with the narrower type mlua rejects a number or
a table during argument conversion, before the closure body runs, and
the message naming the accepted values never appears. That is the same
trap the `dest` argument documents one position to its left. `nil` and
absence are the same answer; anything else is refused by one message
that names both accepted values.
