Levi Neuwirth 90fc7a913e fix(window): wire the side-window split guard and scope the divider drag
PR #155 review round 1.

Finding 1 (must fix): `try_split_active` had no production caller —
`pmacs.window.split_horizontal` / `split_vertical`, and therefore
`C-x 2` / `C-x 3`, still went through plain `split_active`. Splitting a
focused panel made the root wrapper's final child a split rather than
`Leaf(side)`, which both `Layout::compute`'s fixed pass and
`document_subtree` key on: the panel band reverted to 1:1 weight
division and an ordinary window ended up living inside it. Both bindings
now route through the guard, and acc26 asserts through the real Lua
path — a direct core call passes with the guard unwired, which is how it
survived the first round.

Finding 2: the armed-drag early return now checks the arming frontend,
so one frontend's in-flight gesture cannot cancel or swallow another's
mouse events. New acc30c.

Finding 3: `paint_mode_line_graphemes`'s doc block was left heading
`paint_divider_segment`; moved back.

Finding 4: a recompile carries no `display`, so it took the raw switch
and duplicated a panel-placed `*compilation*` into the document window.
`start_run` now detects that the buffer already owns the panel slot.
`pmacs.window.buffer` gained an optional window argument so an adopter
can ask without selecting the panel first. New acc19b.

Stage-2 hazard pins the review asked for, both in `src/daemon.rs`:
a fresh attach while LOCAL is focused in a panel inherits LOCAL's
document buffer, and an initial-target bootstrap whose `after-load`
hook creates and selects a panel still reasserts into a document window.

Minor: dropped listview's dead `p.side`; documented `focus_window`'s
caller-validates contract; `jump_back` restores through `focus_window`
so the "every focus change" contract holds; `params` / `resize` default
to the acting frontend's selected window rather than the ambient one;
widened the flexible-division math to u64 intermediates.

Levi Neuwirth 683c9b86aa feat(window): adopter placement opt-in and the Stage 1 acceptance suite
- `listview.open`, `compile.run`, and `pmacs.terminal.open` all take the
  same strict `display = "current" | "panel"`, validated before any
  buffer, session, process, or wrapper exists. Omission keeps today's
  behavior; Stage 3 flips the default.
- `listview.quit` / `compile.quit` delegate to `window.quit` only when
  the buffer really is in a side window, so the presentation is deleted
  or restored instead of leaving a source buffer stranded in the slot.
- LSP `visit_location`, LSP go-to-definition, and compile `visit_error`
  route through `display_file`, so a visit from a panel lands in the
  document target and fires its hook with that window active.
- `window.quit`'s Delete arm focuses the revalidated remembered origin.
- Capability fallback discards an accompanying `height` rather than
  rejecting the call.
- `window.min-height` clamps a below-floor value on read instead of
  refusing the write.
- `tests/bottom_panel_stage1_acceptance.rs`: 42 tests over the framing's
  Stage 1 criteria, including the two production `Layout::compute`
  callers, the recursive minima, hide/reappear, the final-focus matrix,
  quit chains at the depth cap, per-frontend jump origins, the divider,
  and a real-PTY pin of Bet B1.

Levi Neuwirth 6c8a76e235 feat(window): window parameters, fixed extents, and the display policy
Stage 1 substrate for the bottom-panel arc (docs/bottom-panel-framing.md).

- `WindowParams` (side / fixed_rows / dedicated + implementation-owned
  quit action and remembered document origin), `Side`, `QuitAction` with
  a bounded replacement history, and the `MIN_WINDOW_OUTER_ROWS` floor.
- `Layout::compute(area, fixed)` allocates fixed rows before dividing the
  remainder by weight; both production callers feed the same shared map,
  including the peer-presence overlay pass that derives its own rect.
- `subtree_min_rows` / `interactive_min_rows`: the recursive minima, and
  `boundary_below` for the shared drag / keyboard resize boundary rule.
- `FrontendView` gains `panel_capable`, `frame_geometry`, and the derived
  `panel_hidden`, each spelled explicitly at every construction site.
- `EditorCore`: `primary_document_window`, the non-side target rule,
  `display_buffer` + placement policy, `quit_window`, side-window removal
  on `kill_buffer`, per-frontend jump entries with origin windows, and the
  shared resolve/load-without-switch seam the initial-target bootstrap now
  uses too.
- `EditorState`: the panel reconciliation transaction, geometry
  declaration, the side-window `dispatch_idle_for` gate, divider paint,
  and divider drag.
- `pmacs.window.display / display_file / quit / panel / params /
  set_params / resize / display_target`, plus `builtin/runtime/window.lua`
  with `window.panel-height`, `window.min-height`, and the resize commands.

Levi Neuwirth be8c67c30c fix(daemon): contain failed target sessions
Shut down bootstrap sockets on every dispatcher-side failure and reject
frontend events whose session state was never installed. This prevents a
lingering failed client from reaching absent render/size state.

Track target-side CRDT upgrades independently from load/create status so a
deduplicated hidden buffer is published to every existing grid replica. Add
real-daemon regressions for both failure containment and replica publication.

Levi Neuwirth e6ace5c320 fix(fold): choose the projection in the crdt-gated daemon fixtures
`cargo test --lib --features crdt` compiles two `#[cfg(feature =
"crdt")]` daemon tests that call `build_fresh_frontend_view`. Both model
a semantic session, so they pass `false` — the Q#FD21 value a
`semantic_render` attach gets until Stage 3. Bet B8 in the framing is
exactly this: the projection is chosen explicitly at every construction
site, never inferred, so a new call site cannot silently default.

Levi Neuwirth 313b1ff77a feat(fold): Stage 2 — grid (daemon-rendered) collapse
Implements docs/folding-stage2-framing.md rev 4. The daemon grid
renderer now consults the fold store: hidden lines are omitted, rows
below shift up, and every consumer that assumed
`display_row = source_line - view_top` routes through one shared
projection. No wire schema change and no protocol bump (Bet B6) — the
collapse is entirely daemon-side; the GPU path is Stage 3.

The spine (Q#FD12) is `src/fold_view.rs`: a `VisibleLineMap` derived
from `FoldRegistry::folds` plus a window's line offsets and never
stored. Its unit is a merged **hidden component** — overlapping OR
adjacent hidden intervals unioned, each keeping the one visible
`head_line` and that line's exact `head_position`. Adjacent intervals
merge because the later fold's head is itself hidden, which is what
makes nesting, shared heads, and crossing overlap all resolve to a
head that can actually render (round-3 F2).

Instances are short-lived and built **per rendered window** and **per
command/event operation**, never once per frame: `paint_frame` renders
several windows that may show different buffers, so a singleton would
leak one pane's folds into another (round-2 F2). The render instance
rides on a lifetime-bearing `Viewport<'a>` as `Option<&'a
VisibleLineMap>` — a shared ref is `Copy`, so `Viewport` stays `Copy`
(Bet B7).

Rendering:
- `TextView::render` walks visible lines; the head line gets a
  trailing content-area ellipsis (Q#FD13).
- The gutter walks visible lines too: Absolute keeps the raw `line+1`,
  Relative/Hybrid measure VISIBLE distance anchored on the cursor's
  visible head (Q#FD14). The fold glyph takes the col-0 sign cell only
  when a gutter exists — line numbers default to Off, so with no gutter
  the ellipsis is the sole marker (Q#FD20, round-1 F3). A diagnostic
  clamped onto the head wins that cell by paint order.
- A diagnostic on a hidden line clamps its SIGN to the outermost
  visible head (most-severe merge); the squiggle needs a real row, so
  only the sign clamps (Q#FD15).
- Caret, local selection endpoints, and peer cursors project via
  `visible_position_of` — the head row AND the head's end-of-content
  column, never an arbitrary column (round-2 F3). Peer presence derives
  the RECIPIENT window's map.
- Style/search/completion overlays route through
  `Viewport::row_offset_of`; the mode-line indicator reckons in
  visible-line space.

Command/event time is scoped per frontend (Q#FD21): a
`fold_projection` flag on `FrontendView`, set at attach from the
negotiated `semantic_render` bit (grid ⇒ true, semantic ⇒ false until
Stage 3, LOCAL ⇒ true) and never inferred from a `FrontendId` (Bet
B8). Without it, shared `EditorCore` motion would make a simultaneous
unfolded GPU session's cursor skip lines it still displays. The map's
two axes stay separate (round-3 F1): the acting frontend supplies the
policy, the operation's TARGET window supplies the buffer — a wheel
event names a pane without activating it.

Motion (Q#FD17, ruled: include), paging, wheel, the click inverse, and
the auto-scroll clamp all step by visible lines under that gate;
motion from a hidden logical cursor normalizes to the visible head
first. `view_top` stays a source-line index (Bet B5), set only via
`clamp_view_top` so it never rests hidden.

Unfold widening (Q#FD19): the pre-edit unfold moves to the top of
`apply_active_edit` — one funnel that subsumes the six primitives'
calls and covers yank + query-replace, both of which place point at
the edit site first. Interactive Lua mutators hook the common
`run_buffer_edit`, above the managed/bypass split, gated on
`InteractiveCommandOrigin` AND the edit targeting that frontend's
active-window buffer. The remote/optimistic-CRDT path stays excluded
(Stage 3); undo/redo unfold stays deferred.

Acceptance: `tests/folding_stage2_acceptance.rs`, 35 tests asserting
on the real `paint_frame` cell grid, covering framing items 1–14
including crossing folds, a nested deeply-hidden cursor, a split of
two different buffers with an inactive-pane wheel, and simultaneous
grid+semantic motion.

Levi Neuwirth 2dd30ec730 Implement session-scoped GPU initial targets
Add protocol-v20 semantic bootstrap and readiness result framing so
`pmacs --gpu FILE` opens the requested path before the GPU window becomes
ready. Keep target identity scoped to the authenticated frontend, preserve
legacy/no-target attach behavior, and publish fresh buffers coherently to
existing replicas.

Carry Unix path bytes and launcher cwd through the root broker, resolve paths
lexically in the daemon, reuse or create buffers without ambient-view state,
and preserve the managed daemon lifecycle from #141. Add focused parser,
wire, lifecycle, hook, isolation, and real-connector acceptance coverage.

Levi Neuwirth 9ff6a62623 fix(vterm): address stage 3 review round 2
One real defect, three cleanups, and a named deferral.

A daemon disconnect in terminal mode hid the disconnect notice. The
Disconnected arm set the placeholder text but never left terminal mode,
where the document code layer is not prepared at all and the terminal glyph
layer keeps painting its last frame — so the user was left looking at a
frozen, live-looking terminal that silently ignored input. GPU auto-reconnect
is a named deferral, so that state persisted until relaunch. State::
on_daemon_disconnected now leaves terminal mode, forces a repaint even when
the notice text is byte-identical, and requests a redraw.

The fix and its test share a file, so scripts/bite's file granularity cannot
bite it; the equivalent was done by hand. Neutralizing only the
exit_terminal_mode() call makes the test fail on the "must leave terminal
mode" assertion; restoring it makes it pass.

sync_semantic_terminal_layout no longer clones the whole visible cell grid to
read one size. It ran every dispatcher tick for any semantic frontend with a
declared terminal; TerminalManager::screen_size reads the value from the
borrowed projection instead.

Inbound terminal events now require a negotiated v19 session. The outbound
TerminalFrame was gated twice while TerminalResize/TerminalPointer relied on
the frontend's send gate alone. A pre-v19 peer cannot construct those
variants, so this only refuses a hand-rolled client — and the a32 forgery
tests already prove such an event reaches nothing but the sender's own
authenticated active view — but the asymmetry was not deliberate.

A terminal-mode press that misses the grid no longer arms a drag, so a later
in-grid motion cannot send a Drag with no preceding Down. Daemon-side impact
was nil; the state is now honest. A release still always ends the drag.

The roadmap and handoff Arc 5 lines still said Stage 3 was framed and
awaiting approval, contradicting this PR's own ledger. Both corrected.

Named deferral: terminal wheel gestures discard scroll magnitude. One winit
wheel event becomes one gesture regardless of the lines it accumulated, while
the document path scrolls by lines. Closing it means either N gestures
(chattier) or a magnitude field on the pointer event — a protocol change.
Neither belongs in this stage.

Levi Neuwirth 50fd9a08e4 fix(vterm): address stage 3 review round 1
Five findings, all addressed. One was a real defect; one prediction did not
reproduce and is documented as such rather than papered over.

Hover no longer claims durable terminal control (finding 2, the real one).
apply_terminal_gesture claimed the controller before dispatching, including
for Move, which does nothing. A semantic frontend reports motion at pixel
rate, so sweeping the mouse across a passive split's terminal took durable
control, and the next layout sync resized the shared PTY to that background
view's geometry — precisely the theft the controller rule exists to prevent.
Bare motion no longer claims; every deliberate gesture still does.
scripts/bite HEAD src/editor.rs on the new test is a clean behavioral bite.

The terminal-mode presence-sweep skip is removed (finding 1), but the
predicted failure did NOT reproduce. The review reasoned that skipping the
sweep freezes last_broadcast at the abandoned document position. It does
not: the buffer-follow clears the terminal declaration when it ships the
snapshot, so terminal_active is false on the tick a window first shows a
terminal, and the declaration cannot arrive until a later tick — the
frontend learns the buffer id from that very snapshot. One truthful sweep
always lands first. The real-daemon two-frontend test written to catch the
freeze passes against the pre-fix tree; the bite is vacuous and the test is
labelled a regression guard, not fix evidence. The skip goes anyway: it was
load-bearing on tick ordering and bought nothing, and removing it makes
"presence follows the frontend" structural.

Terminal motion is deduplicated by cell (finding 3). Sub-cell motion
resolved to the same coordinate and still crossed the wire, where every
event is a daemon-side gesture. Press and release re-arm the memo so the
first drag after a press still reports. Its unit test cannot bite — the
seam did not exist pre-fix — and says so.

Declarations record only once sent (finding 4).
terminal_declaration_if_changed is now a pure query;
note_terminal_declaration_sent records. A failed write is retried instead of
suppressed as already-declared. The existing a35 test caught the contract
change and now pins both halves.

Unchanged frames skip revalidation (finding 5). The complete-payload
comparison runs before validate; only validated frames are ever stored, so a
frame equal to the baseline has already passed. The chrome tail is factored
into terminal_chrome so both exits emit it identically.

Levi Neuwirth bdf2b6e4b4 feat(vterm): protocol v19 terminal frames and a native GPU terminal
Vterm Stage 3 — the final vterm stage. A semantic frontend can now host a
terminal: the daemon ships complete validated cell grids, and pmacs-gpu
renders them with fixed-cell geometry, its own input path, and no document
projection at all.

Protocol v19 appends three variants after their enums' final v18 members:
InstanceMessage::TerminalFrame (daemon-gated), and FrontendEvent::
TerminalResize / TerminalPointer (frontend-gated). It is the first bump to
gate in both directions, so criterion 28 pins each filter independently and
byte pins on StatuslineSegments and MenuPointer guard the placements.

pmacs-protocol gains src/terminal.rs: the shared row/column/visible-cell/
grapheme/metadata bounds, TerminalProcessState, TerminalSelectionSpan, and
TerminalFrame::validate — the ONE structural policy the daemon runs before
emission and the frontend runs after decode. src/terminal/* re-exports them
so no duplicate type exists, and unicode-width becomes a workspace dependency
so the screen and the validator measure glyph columns with one table. A new
8 MiB aggregate glyph bound keeps the largest legal frame (measured:
13,437,863 bytes) under the unchanged 16 MiB transport cap rather than
widening every connection's allocation ceiling.

The semantic producer suppresses the whole document family for a terminal
buffer while keeping the status band, theme, font, statusline, menu, and
minibuffer, and compares the complete ordered payload rather than
screen_generation — scroll, selection, and process state all change without
advancing it.

Two things the framing did not spell out, both found by the real-daemon
acceptance:

The Viewport gate keys on the authenticated source's ACTIVE buffer, not the
buffer the message names. Viewport also aligns the window to what it
declares, so a stale document viewport in flight when a command opened a
terminal dragged the frontend straight back off it: the window oscillated,
every terminal declaration was refused, and no frame ever arrived, with
nothing logged anywhere.

The producer clears terminal mode on every exit path. The daemon uses that
flag to suppress CursorByte and the presence sweep, so an early return that
left it set kept both suppressed after the frontend returned to a document.

pmacs-gpu/src/terminal.rs is a pure cell-space paint planner, unit-testable
without a GPU. The renderer builds one shaped buffer per text run, so a wide
or cluster glyph's advance can never choose the next column's origin.

Criterion 37 needed a seam rather than a fixture: pmacs-gpu depends only on
pmacs-protocol, so attach::connect's reader sink was generalized and a
--headless-probe mode added. The acceptance drives a real daemon, a real
/bin/sh child, the real attach client, and real composited pixels in one
path — which is how both defects above were found.

Levi Neuwirth 661b4968d9 feat(font): FontFacts wire + daemon half (v17, FontPref, producer)
Protocol v16->17: InstanceMessage::FontFacts { family,
size_centi_px } appended after ThemeFacts (integer hundredths of a
logical pixel -- the enum derives Eq, f32 cannot; range 600..=7200
documented on the wire). Pins updated: version 17, ladder accepts
6..=17 rejects 18, FontFacts round-trip (populated + all-None), and
a ThemeFacts byte pin ([23, 0]) guarding the appended placement.

Daemon half: FontPref { family, size_centi_px, epoch } behind a
shared handle on EditorState, installed with the new pmacs.gpu Lua
module BEFORE load_user_config so init.lua set_font lands in the
state the first attachment reads. set_font is strict plain data
(raw_get, unknown raw keys rejected by name, metatables never
consulted, parse/validate/quantize fully before locking -- range-
check the ORIGINAL value so 5.999 errors, then nearest-hundredth
round); pmacs.gpu.font() returns a fresh quantized table.

Producer: font_facts_msg (the theme_facts_msg discipline --
Option-seeded epoch + payload baselines, advance on computation,
one authoritative send per attachment incl (None, None),
bufferless so on_buffer_snapshot_sent never touches it); for_peer
gains peer_knows_font_facts (>= 17); daemon write-loop skip arm;
TUI silent-drop arm + regression test; first-frame count test now
expects 6 messages. GPU application follows in the next commit.

Levi Neuwirth d91ff1a9e2 fix(themes): PR #120 round 2 -- snapshot/baseline reset contract
Finding 1: a BufferSnapshot wipes the frontend's buffer-scoped
render state (spans, decorations, adornments, minimap summary,
completion popup), but the producer's per-buffer emission baselines
survived the switch -- on an unchanged A -> B -> A round trip,
last_summary[A]'s key still matched and the daemon emitted nothing,
so the frontend never regained A's themed minimap (or A's
StatusFacts: the band kept B's name) until an edit, republish, or
theme mutation happened to move the key.

The fix is the general contract, not a minimap special case:
SemanticRenderState::on_buffer_snapshot_sent(buffer_id) kills every
buffer-scoped baseline for that buffer (spans + style gate,
decorations, adornments, summary, status, search/menu prompts,
completion popup), called wherever the daemon writes a snapshot --
the active-buffer-follow path and the F29 upgrade broadcast; the
attach bootstrap constructs its session state fresh. Deliberately
surviving: the bufferless ThemeFacts pair, the global minibuffer
baseline, the per-frontend gutter mode, the revision-keyed diag
line cache, and other buffers' baselines.

Evidence: a producer round-trip acceptance test (themed summary and
StatusFacts return at the SAME generation; identical payload), a
real-daemon wire test driving A -> B -> A via dispatched keys
(runtime bite: times out against pre-fix daemon.rs), a Rust unit
pinning the reset's scope, and a GPU test where the re-shipped
summary restores the first visit's pixels exactly (frontend half --
no GPU code change, coverage only). The semantic_render.rs bite is
compile-fail (the hook is absent pre-fix), disclosed as weaker.
The protocol doc's composition section now states the snapshot
reset contract on both sides of the wire.

Finding 2: the acceptance-suite manifest header now lists the true
item split (1-19, 24-26, 28-29 here; 20-23, 27, 30 in the GPU
suite). Framing revision 6 folds the round; acceptance items 28-30.

Levi Neuwirth 3083458cb0 fix(themes): PR #120 round 1 -- minimap cache, __index holes, v15 face leak
Finding 1: accepting a FileStyleSummary drops the GPU minimap vertex
cache -- theme recolors and diagnostic republishes arrive at an
unchanged generation, and the cache keys only on (generation, dims,
scroll), so stale strokes survived until an edit/resize/scroll. The
daemon payload-suppresses identical summaries, so the invalidation
is precise. GPU test drives two same-generation summaries;
hand-bitten by reverting the single invalidation line (script-bite
is vacuous here: fix and test share main.rs).

Finding 2: lua_to_style propagates every Table::get error -- the
lookups run __index, so a raising metatable previously parsed as an
all-default style and the merge SUCCEEDED, committing valid siblings
against the Q#TH6 all-or-nothing contract. Boolean fields keep Lua
truthiness by design (mlua bool), so only raising lookups fail the
transaction. Acceptance reproduces the reviewer's trap shape;
runtime bite vs pre-fix mod.rs.

Finding 3: SemanticRenderState::for_peer records the negotiated
version; below v16 no ThemeFacts is produced and no ui.diag.* face
folds into the FileStyleSummary marks -- the summary is an ungated
pre-v16 channel, and a v15 peer must not get face-derived minimap
colors while its other severity surfaces stay unthemed. The summary
cache key zeroes its face-epoch component for such peers. Acceptance
drives v15/v16 producers side by side; compile-fail bite disclosed
(the test needs for_peer, absent pre-fix).

Finding 4: framing revision 5 weakens the canonical-severity claim
to what is true -- the daemon-RESOLVED color is canonical, while the
GPU's built-in squiggle/sign/counter defaults are historical bright
RGBs that differ from the minimap's converted Indexed marks, a
pre-existing divergence kept because unset faces must render
byte-identically to before.

Levi Neuwirth 7975eeda87 feat(themes): named UI faces + ThemeFacts channel (protocol v16)
Arc 4 stage 1 (docs/theme-faces-framing.md, revision 4). Faces are
theme entries under the reserved ui/ui.* namespace -- zero new Lua
API. Theme::face() resolves with the dotted-prefix walk but never
falls back to default_style; each face applies owns-surface within
its stage-1 component mask, identical on both frontends.

Substrate: two monotonic theme mutation counters (syntax/face) with
transactional set/merge/clear/default (parse before locking, commit
all-or-nothing, bump from the prior value); the StyleGate and the
minimap summary key on the counters -- fixing the pre-existing bug
where a mid-session pmacs.theme.set never re-shipped StyleSpans --
with the summary gaining payload-equality suppression that still
advances its key on computation.

Wire: InstanceMessage::ThemeFacts appended after CompletionPopup
(postcard discriminants are ordinal; a byte pin guards placement),
PROTOCOL_VERSION 15 -> 16, daemon-gated >= 16, one authoritative
table per attachment (None-seeded baselines), TUI silent-drop arm.

Grid: paint_frame resolves ui.modeline / ui.statusline /
ui.minibuffer(.candidate) / ui.gutter / ui.selection faces;
SearchView and DiagnosticView take the theme handle through the real
attachment paths (EditorCore injection, install_diag threading); the
canonical severity color resolves ui.diag.* with the Default ->
built-in policy that keeps the minimap presence encoding sound.

GPU: exact-name face table applied per draw with the Q#TH5 Default
mapping (plain text / window bg, reverse swap), local/peer wash
split, candidate-dropdown glyph site, and the status-band
shaping-cache invalidation without which a diag-face recolor with
constant counts kept stale counter colors.

Tests: 18-test acceptance suite (grid, wire, daemon gate, atomicity,
monotonicity, late join), 7 GPU headless tests incl. decoded vertex
colors, units for the face walk / transactional commits / producer
caches; protocol pins for v16 + the CompletionPopup byte pin.
Bites vs 3cbb9de (scripts/bite): semantic_render.rs (8 runtime test
failures), editor.rs (5 runtime), daemon.rs (v15 gate, runtime);
lua_bindings/mod.rs, pmacs-gpu/main.rs, search.rs, diag.rs, and
highlight.rs bite as compile failures (weaker evidence, disclosed).

Levi Neuwirth b0bbc86792 fix(edit): PR #110 round 1 — revision postcondition, relevance gate, strict pair parsing
Finding 1 (medium): the typed-edit record now pins the edited
buffer's revision after the completing edit; typed_edit_finish
re-reads it at dispatch end and drops the record if the command
edited again — a redefined buffer.self-insert that replaces the typed
char (cursor unmoved) no longer leaves a stale-but-clean record, so
`(`-then-replace-with-`[` yields `[`, not `[)`. Bite:
post_insert_mutation_by_the_command_kills_the_record.

Finding 2 (medium): pair-set relevance is established before the
clean/context gates, so a transformed or relocated character outside
the active set stays silent instead of drawing an auto-pair report.
Bite: transformed_non_pair_char_stays_silent.

Finding 3 (medium): split_pair parses EXACTLY two codepoints and
rejects trailing bytes — a "()x" (or "«»x") entry is skipped
entirely, never honored as `(` → `)x`; valid multibyte pairs ("«»")
pair and skip at byte-correct cursors. Bites:
malformed_pair_entries_are_skipped_not_partially_honored,
multibyte_pair_entries_pair_and_skip.

Finding 4 (low): the record-capture seam is gated behind the opt-in
pmacs.pair._capture_records test facility, off by default — no
consumed record is retained in production, restoring the Q#AP9
ephemerality the seam had defeated. Seam-reading tests opt in;
record_capture_is_off_by_default pins the default.

Finding 5 (low): the equal-revision source-context-switch twin is
covered — the fan-out is skipped by the active-buffer revision
compare, pairing fails closed silently, and no report is possible;
the framing scopes the context-change report as best-effort until the
buffer-aware edit epoch lands.

Framing synced to revision 4 (Q#AP2 entry rule, Q#AP3 relevance-first
+ best-effort report scope, Q#AP9 revision postcondition + capture
facility + the dispatch-path intercept borrow note, acceptance list).

Levi Neuwirth 223e26420b feat(edit): auto-pairing (Arc 2)
Typing an opener inserts the closer with the cursor between; typing a
closer over its twin steps over it. Q#AP1: the nine built-in pair
chars leave both optimistic classifiers (shared charset in
pmacs-protocol) and round-trip through dispatch, so the opener and the
hook's closer are adjacent daemon-peer undo units, dispatch CUA
type-over applies, and skip never paints a transient duplicate.

Q#AP9: exact one-shot typed-edit provenance. EditorCore's
apply_active_edit now returns the effective Edit; the dispatch
fallback arms a per-frontend record (codepoint + requested vs
effective ranges + post-cursor + clean verdict) that insert primitives
complete and the daemon's optimistic CRDT arm builds directly. The
record is takeable exactly once via pmacs.editor.take_typed_edit()
during the one after-edit fan-out, then cleared — paste, programmatic
edits, manual hook runs, nested re-runs, rejected edits, and stale
this_command all observe nil, and transformed / relocated /
context-switched source self-inserts fail closed with a status.

pair.lua (loaded BEFORE lsp.lua — ordering contract in editor.rs):
per-language pmacs.pair.sets with a conservative default (no ' or `),
EOL/whitespace/closer insertion predicate, reactive skip-over-close,
rejected/transformed intercept outcomes with context-guarded
translate-and-clamp cursor repair.

Acceptance: 32 dispatch-driven cases (predicate, skip, per-language
sets, non-typed provenance incl. production-shaped paste, type-over,
undo/redo grain, intercept outcomes on both the source and reaction
edits, context-switch probe, record lifecycle, frontend isolation) +
first-didChange ordering against the fake LSP's sighelp mode via a
new PMACS_FAKE_LSP_CHANGE_SINK replay file. Six two-replica CRDT
cases pin dispatch-route convergence with cursor-between, undo/redo
walking the pair on both replicas, both mixed-history undo models as
named substrate limits, and the optimistic custom-char route
(closer-broadcast-before-opener convergence, degraded cross-peer
undo). TestDaemon gains spawn_with_config for init.lua-extended pair
sets.

Framing: docs/auto-pairing-framing.md (revision 3).

Levi Neuwirth 180343e6e3 fix(edit): PR #109 round 1 — shared search invalidation, daemon anchor clear, bounded indent scan
Finding 1: the empty-anchor optimistic residual was never GPU-only
(the TUI mirror tracks no selection state; its gate checks cursor
freshness/EOL only). The fix moves daemon-side: handle_remote_crdt_op
clears a selection whose anchor equals the pre-edit cursor (= empty)
before applying the source cursor update; nonempty selections stand.
Covers both frontends. The TUI gate's missing type-over check
(nonempty selection at EOL) is a named deferral.

Finding 2: Q#AI8 invalidation is one helper
(search_invalidate_for_edit) invoked from all four edit paths --
apply_active_edit, notify_buffer_edit, and now undo/redo, which
received precise Edits but invalidated nothing. rebuild_views_for is
named as a lower-frequency bypass (deferral).

Finding 3: acceptance matrix trued up -- added active-search
fail-closed + retype recovery, delete translation on both paths,
undo/redo staleness + origin tests; modal contexts narrowed to what
this suite pins (query-replace/menu/completion ride their own
suites).

Finding 4: indent extraction is a forward-chunked scan stopping at
the first non-whitespace byte -- Enter at the end of a giant
minified line no longer materializes the line. Functional pin at
64 KiB.

Both medium fixes are bite-verified (tests fail with the fix
disabled).

Levi Neuwirth 625128c139 fix(lsp): range-only providers, completion-accept boundary, exact codepoint classify
Addresses the round-4 findings against the stack (PR #104 portion).

- HIGH range-only semantic-token servers: LSP defines
  semanticTokensProvider.full and .range as optional, INDEPENDENT
  capabilities, but the old any-provider gate sent /full regardless — a
  range-only server rejects it and the swallowed error means no styling,
  ever. Both the auto-pull and the manual command now gate each request
  kind on its own capability: /full (delta under full.delta) when
  negotiated; a range-only provider gets a WHOLE-DOCUMENT /range request.
  New `rangeonly` fake mode (advertises range without full, rejects
  /full) + test proving tokens arrive via the range path.

- MEDIUM completion acceptance left this_command stale: the popup accept
  applies its edit and fires after-edit outside command dispatch, so
  this_command could still read "buffer.self-insert" from the typing that
  raised the popup — a candidate ending in "(" would spuriously
  auto-trigger signature help. Accept now stamps its own boundary
  ("completion.accept"); asserted in the popup acceptance suite.

- MEDIUM GPU shape inference tightened: the 1-4-byte predicate accepted
  a 2-byte "a(" insert (two ASCII codepoints). The classifier now decodes
  the inserted bytes from the post-edit rope and requires the leading
  byte's UTF-8 sequence length to equal inserted_len — exactly one
  codepoint. The daemon unit test now drives an "a(" op and asserts it
  breaks the chain instead of classifying as typing. Exact wire
  provenance on the CRDT op remains the named deferred general fix.

Gates: fmt + workspace clippy clean; lib 1500; crdt 1672; m4 98;

Levi Neuwirth 5c2a27aaf9 fix(lsp): negotiate delta before requesting; input-origin signature trigger
Addresses the four post-merge findings against PR #102 (merged as
2d157d8). Stacked on the kill-ring branch (PR #103): the trigger
redesign rides its command-boundary substrate.

- BLOCKING delta without the capability: pull_semantic_tokens_quiet (and
  the pre-existing manual pmacs.lsp.semantic_tokens(), same bug) used
  any stored resultId to request /full/delta while only checking that a
  provider exists. A resultId does not imply delta support --- servers
  may return one from /full regardless --- and a conforming full-only
  server rejects the delta request; the pull path swallows the error, so
  styling stayed silently stale after the first edit. Both sites now
  require semanticTokensProvider.full.delta == true. The fake's default
  mode truthfully advertises { "full": { "delta": true } } (it
  implements delta); a new `fullonly` mode advertises "full": true,
  REJECTS /full/delta, and bumps its resultId per /full response so the
  test can observe WHICH pull refreshed the store. Verified the test
  bites: with the capability check reverted, the post-edit rid stays
  rid-1 (stale) and the test fails.

- HIGH false-positive trigger + cross-frontend misclassification: the
  cursor-delta heuristic ("same buffer, cursor +1") fired on any
  one-byte edit --- including a one-byte paste of "(" once PR #103 made
  paste fire buffer.after-edit --- and its singleton last_typed was
  shared across frontends. Replaced with the input-origin signal from
  the #103 substrate: inside after-edit,
  pmacs.editor.this_command() == "buffer.self-insert" names an edit
  produced by typing, per frontend, with nothing inferred from cursor
  deltas. New ed.this_command() binding; handle_remote_crdt_op now
  classifies a single-codepoint optimistic insert as buffer.self-insert
  (rotation, not just break --- kill-chain semantics identical since
  self-insert is not a kill, and GPU typing now carries the same origin
  signal as TUI typing). Paste/pointer/undo/unbound leave this_command
  as something else and can never trigger.

- MEDIUM first-trigger-ignored: the origin signal needs no prior-edit
  snapshot, so the very first "(" typed in a buffer triggers. The test
  that had encoded the warm-up keystroke as "correct" now types a single
  "(" as the first character.

- MEDIUM non-ASCII trigger characters: char_before read one byte and
  rejected multi-byte strings; LSP trigger characters are strings. Now
  codepoint-aware (read up to 4 bytes back, take the suffix from the
  last non-continuation byte). The sighelp fake declares a two-byte
  trigger ("«") and a test types it.

Tests (m4_acceptance 94 -> 97 after +4/-1 rework):
arc1c_full_only_server_repulls_via_full_not_delta (bites --- verified),
arc1d_signature_help_auto_triggers_on_trigger_char (now first-char),
arc1d_signature_help_triggers_on_non_ascii_trigger_char,
arc1d_signature_help_ignores_non_typed_edits (movement-stamped
programmatic "(" insert + manual after-edit must not trigger --- the
case cursor-delta inference cannot distinguish). Daemon unit test
updated for the insert classification (break-then-classify: `this` =
buffer.self-insert, `last` = None, chain still dead).

Note: completion.lua still uses the Q#C9 cursor-delta heuristic and
inherits its weaknesses; migrating it to this_command is a named
follow-up, out of scope here.

Levi Neuwirth 04314ce132 feat(edit): kill ring + yank-pop on a per-frontend command-boundary substrate
Arc 2 (docs/kill-ring-framing.md, rev 3 — three review rounds). Kills
accumulate in a ring; consecutive kills append; C-y yanks the head; M-y
right after a yank cycles older entries; C-k (kill-line) exists at last.
The ring is daemon-global (Emacs-daemon model); chains and yank sessions
are per-frontend.

The substrate (Q#KR2): EditorCore.command_history maps FrontendId ->
{this, last} command. Every input path updates it --- the rev-1 design
treated dispatch_key as the only input path and review falsified that
twice:

  keybound command            dispatch_key Run arm          rotate
  typed char (round-trip)     self-insert fallback          rotate
  unbound key                 dispatch_key unbound arm      break
  GPU optimistic edit         handle_remote_crdt_op         break
  pointer gesture             dispatch_mouse + dispatch_pointer  break
  inbound OS paste            unified paste route           break
  menu item                   menu_invoke_active            rotate
  M-x accept                  pmacs.command.invoke_interactive   rotate

invoke_interactive gives Emacs's execute-extended-command semantics
(M-x kill-line then C-k appends; C-k then M-x kill-line does not); the
public pmacs.command.invoke stamps nothing. Wheel scroll deliberately
does NOT break (mwheel-scroll vs mouse-set-point, as in Emacs).

Three shipped bugs fixed en route (Q#KR10):
- Semantic-path Paste was dropped ("no grid-less effect yet"), and the
  GPU always negotiates semantic render --- GPU Ctrl-V was a no-op. Paste
  is now a dispatcher-level arm serving both attachment kinds.
- That arm keys off the dispatcher's AUTHENTICATED source; the old grid
  arm trusted the client-supplied payload frontend_id, letting a forged
  id paste into another frontend's active window (unit-tested).
- Paste, M-x-invoked commands, and menu-invoked commands never fired
  buffer.after-edit (each runs outside dispatch_key's revision check),
  so LSP/syntax/autosave missed those edits. A shared
  with_after_edit_check helper now wraps all three sites; scope is
  honest --- active-buffer compare, sound for these paths, not a general
  any-buffer guarantee (buffer-aware edit epoch deferred).

The ring (killring.lua, Q#KR4-7): entries carry stable monotonic ids.
Append requires last_command in the kill family AND this frontend's
last_kill_id == the head's id --- A-kill/B-kill/A-kill pushes fresh
instead of corrupting B's entry. Yank sessions store {buffer, start,
stop, entry_id, text}: M-y validates last_command + live session + same
buffer + slice(start,stop) == text (out-of-bounds reads as changed ---
pcall'd; an early test caught the guard throwing on an upstream
deletion instead of refusing), rotates by locating the entry_id's
CURRENT position (positions shift under other frontends' pushes; ids
don't), verifies the applied replace (intercepts may alter it; accepted
post-hoc semantics), then goto_byte. Failed kills clear last_kill_id;
failed/refused yanks create no session, so a second invalid M-y cannot
ride the first's name-stamp.

OS clipboard: ring head mirrors to the ACTING frontend's OS clipboard
only (pending_clipboard's existing shape; frontends may be different
machines). External content joins the ring at yank time via the
clipboard_get slot check (an OS copy reaches the daemon only when
pasted). New core seams: clipboard_set(bytes) / clipboard_get.

Lifecycle (Q#KR11): SessionDetached prunes command_history and fires the
new frontend.detached hook (raw id); killring.lua drops that frontend's
tables.

pmacs.killring.max([n]) validated (non-finite rejected --- math.huge
would defeat the cap; shrink trims immediately), default 60.

Deferred, named: word kills (M-d/M-BS/C-BS/C-h/C-DEL discard bytes ---
needs bytes-returning deleters), C-SPC/set-mark, clipboard watching,
ring browser/persistence, C-u C-y / C-M-w, buffer-aware edit epoch,
Lua-visible intercept probe.

Tests: tests/kill_ring_acceptance.rs (24) --- chain mechanics incl. all
break rows, the M-x three-direction matrix, per-frontend interleaving
(A-kill/B-kill/A-kill; stable-id rotation under B's pushes; eviction
mid-session; upstream-edit invalidation), menu Cut via real right-click
+ menu pointer (feeds ring, fires after-edit once, chains with C-k),
external-paste integration, cap validation + shrink-trim, detach
cleanup. Plus daemon unit tests: forged-id paste lands in the
authenticated source's window and leaves the claimed frontend's chain
untouched; optimistic CRDT op breaks only the source's chain.

Levi Neuwirth 3607df0afe feat(persistence): desktop-save --- buffers + layout + positions (Arc 3 phase 2)
Framing: docs/desktop-save-framing.md (Q#DS1-10). Save the open file
buffers, window layout, and per-window positions on quit; rebuild them
on startup. Emacs desktop.el, opt-in, local-mode only in v1.

All-Rust (Q#DS1) --- the core window enums are not serde and there is
no Lua tree API, so the layout mirror + structural rebuild live in Rust.
Lua adds only the opt-in switch and manual commands.

src/desktop.rs (new):
- Serde mirror (SavedDesktop / SavedBuffer / SavedNode / SavedLeaf /
  SavedOrientation): every open file buffer (visible OR hidden, so a
  switched-away file survives), the layout tree with orientation +
  weights + nesting, per-leaf cursor/view_top, and an active-leaf
  preorder index with a nearest-neighbor fallback (Q#DS10).
- session_key: SHA-256, name.<hex> when a socket name is set else
  cwd.<hex> (charset-safe for the pmacs.state key).
- save_session / restore_session take the &Lua that carries the
  SharedCore / StateDir / LocalInstanceInfo app-data, so they run
  identically from a pmacs.session.* binding and the startup trigger.
- restore ordering (Q#DS3): open all buffers; prune EVERY window of the
  old LOCAL layout (not just scratch); rebuild the tree; then per leaf
  in preorder activate its window and fire buffer.after-load once per
  newly-loaded buffer (hooks read active state), and write the exact
  cursor/view_top AFTER so desktop wins over saveplace (same file in two
  panes keeps distinct positions). A missing file collapses its leaf.

src/editor_core.rs: get_or_load_buffer(path) --- find_by_path else
load fresh, WITHOUT switching the active window; returns (id, newly).

src/lua_bindings: pmacs.session.{save_desktop, restore_desktop,
arm_restore, is_daemon}; DesktopRestoreArmed + DaemonMode markers;
fire_after_load_hook seam.

builtin/runtime/desktop.lua: pmacs.session.desktop_mode(on) wires
before-quit save + arms restore; desktop-save / desktop-restore
commands. No-op under a daemon (Q#DS9).

Startup trigger (Q#DS7): editor::run captures had_file before the match
consumes `file`, and restore_desktop_if_armed runs INSIDE the RunLocal
arm (after attach dispatch) so a hand-off to attach never populates an
EditorState it is about to drop. Daemon marks DaemonMode → desktop
stays local-only.

Tests: src/desktop.rs units (tree collapse, active-leaf fallback,
key/json round-trip) + tests/desktop_acceptance.rs (9): nested weighted
round-trip, hidden-buffer survival, after-load-active probe, same-file
two-pane distinct positions, missing-file collapse + focus fallback, no
orphan windows, name-vs-cwd key scoping, modified warning, startup gate.

Levi Neuwirth d5d75e63ed fix(persistence): symlink confinement, real test-inertness, view_top restore
Addresses the PR #98 review:

- HIGH symlink escape: resolve() did only a lexical starts_with, so a
  base/autosave symlink -> /tmp/out let state.write("autosave/x") write
  outside the state dir. Now every existing component the key adds under
  base is lstat'd and a symlink (live OR broken) is rejected; base itself
  may still be a symlink (dotfile-managed ~/.local/state). Unix symlink
  escape test added (live + broken + plain-subdir-ok).

- MEDIUM integration-test state leak: the state/history dir wiring moved
  out of EditorState::new() into EditorState::install_state_dirs(),
  called only by the real entry points (editor::run, run_daemon). Unit
  AND integration tests construct EditorState directly, so they never
  configure a real dir -> default-on recentf/saveplace write nothing to
  ~/.local/state/pmacs during cargo test. The inertness test now asserts
  a bare new() leaves StateDir unconfigured (direct proof).

- MEDIUM saveplace never recorded view_top: exposed the missing
  pmacs.editor.view_top() getter (set_view_top existed but no getter, so
  the Lua stored 0). saveplace now records+restores the viewport;
  acceptance asserts view_top restores, not just the cursor byte.

- MEDIUM/LOW relative XDG_STATE_HOME / PMACS_STATE_HOME: a relative
  value rooted state at a cwd-relative pmacs/... (same footgun class as
  the empty case). Both are now required absolute; relative values are
  ignored (XDG falls through to HOME). Test added.

- LOW trailing blank line at recentf.lua EOF (git diff --check).

Levi Neuwirth 157358c57e fix(daemon): follow-active-buffer snapshots are semantic-sessions only
Round-2 regression (TUI could not attach): the follow path fired for
every crdt_replica session, and its first-tick send delivered a
GUARANTEED duplicate BufferSnapshot right after the attach sweep. The
grid TUI's BufferMirror is init-once -- the duplicate errored ('buffer
already has a CRDT snapshot applied') on every attach, and every TUI
buffer switch would have produced another. Display-follows-snapshot is
a grid-less-frontend concept: the GPU rebuilds its replica wholesale
on every snapshot and is the only consumer that needs the follow. The
send is now gated on negotiated_capabilities.semantic_render -- TUI
sessions get zero follow-sends, byte-identical wire behavior to main.

Verified: PTY-doubled real-binary attach tests pass with the gate;
the one failing PTY test (m10_11_doubled_pty_fixture_propagates_
keystrokes_from_both_sides, 'AXYB' interleaving) fails identically on

Levi Neuwirth 5c5caa9482 fix(panels): follow active buffer on semantic frontends; re-attach overlays on switch
Two PR #94 validation findings.

1. (High, blocking) GPU stuck after leaving a panel: the GPU only
   swaps its displayed buffer on BufferSnapshot, and the daemon only
   sent one on the first CRDT upgrade (F29's ensure returns None for
   an already-backed buffer). A panel's q / RET switched the daemon's
   active buffer back to the already-known source and sent nothing --
   the GPU kept rendering the panel while input targeted the source: a
   typing-into-a-buffer-you-can't-see hazard. Fix: the per-tick loop
   now FOLLOWS each replica frontend's own active buffer -- when it
   differs from the last snapshot sent to that frontend, ship that
   buffer's snapshot to that frontend only (the F29 broadcast records
   itself so the upgrade tick doesn't double-send). First-tick send
   also repairs the attach-time last-snapshot-wins ambiguity. Snapshot
   export extracted and shared with the F29 broadcast; per-fid state
   cleaned on both detach paths.

2. (High, wider than reported) 'LSP doesn't activate on navigate':
   switch_active_buffer clears the window's overlays, and the runtime
   dedup tables (highlighted_buffers, styled_buffers,
   diag_viewed_buffers) blocked re-attachment -- so EVERY buffer
   switch (plain C-x b included, long-latent) permanently stripped
   syntax color, LSP semantic style, and diagnostic underlines;
   verified: overlay kinds [syntax-highlight, lsp-style, diagnostic]
   -> [] after one away-and-back. Fix: a new additive
   buffer.after-switch hook, fired by the window.switch_buffer binding
   and find_or_open's existing-buffer branch; syntax.lua and lsp.lua
   subscribe and re-push their views (the just-cleared window makes
   that exactly-once per switch; fresh loads keep firing after-load).

Regression: tests/overlay_reattach_acceptance.rs (double round-trip
counts exactly one highlight overlay; panel q restores styling).
The daemon follow path is validated live (daemon + GPU) -- its unit
seam is the shared export helper.

Levi Neuwirth 34188c0528 fix(completion): buffer-scope the GPU popup mirror; clear status on optimistic edits
Two pre-merge review findings on PR #93:

1. (High) The BufferSnapshot arm switched current_buffer_id and
   dropped every other buffer-local mirror but left self.completion
   intact -- and the producer's first-sight-closed silence means no
   close message ever arrives for a viewport that no longer exists,
   so a stale popup rendered against the new buffer's rope and kept
   hijacking Esc/RET/TAB. Fixed three-deep: the snapshot arm clears
   the mirror; CompletionLocal now carries its buffer_id; and the
   shared completion_open_for_current_buffer() predicate gates both
   the key routing and the anchor mapping, so a foreign-buffer popup
   can neither paint nor steal keys even if a stale mirror survives
   by some other path. Regression: completion_popup_is_scoped_to_its_buffer.

2. (Medium) Optimistic typing (the CrdtOp path, the bulk of GPU
   keystrokes) never cleared core.status, so once v15 shipped the
   transient message over StatusFacts, '12 references' stayed wedged
   in the GPU band through ordinary typing -- only a round-tripped
   key's dispatch_key entry clear released it. handle_remote_crdt_op
   now clears the status when an edit applies, mirroring dispatch_key.
   Regression: handle_remote_crdt_op_clears_the_transient_status.

Also checked: the a_closed_outbox_shuts_the_socket_down... hang seen
once during review did not reproduce in 10 isolated runs -- a
pre-existing timing flake in the F-008 shutdown test, untouched here.

Levi Neuwirth 05c6519649 feat(status): ship the transient status message to semantic frontends
Validation finding: LSP command summaries ('12 references', hover
first-lines, error reports -- everything pmacs.editor.set_status
writes) showed in the TUI's bottom bar but never in the GPU band,
regardless of which frontend initiated. The attached TUI gets the
message for free through the rendered cell grid's bottom row; a
semantic frontend only sees the wire, and StatusFacts never carried
the message.

Fix inside the still-unreleased v15: StatusFacts gains
message: Option<String> (encoding change to that variant; its daemon
gate moves 8 -> 15, the v10 SearchPrompt / v14 LineNumbers shape --
an old peer's band goes dark rather than mis-decoding). Producer reads
core.status into the cached-compare facts; the GPU band shows the
message echo-area style (under the minibuffer and search prompts,
over the buffer name), returning to the name when the daemon's next
keypress clears it. Producer + postcard round-trip tests added.

The finer-grained results UI (references list, panels, error surfaces)
is Arc 1b on the roadmap; this closes the parity gap until then.

Levi Neuwirth dc26c84b7c feat(protocol): v15 CompletionPopup message + producer + daemon gate (Q#C5)
InstanceMessage::CompletionPopup {buffer_id, anchor: Option<u64>,
prefix_len, rows: Vec<CompletionPopupRow{label, kind, detail}>,
selected, total} -- the first byte-anchored popup on the wire: the
frontend maps byte -> glyph rect locally (the caret precedent), so the
instance never learns a pixel. Rows are display-only; accept resolves
daemon-side via dispatch_completion_key, so insert text never ships.
PROTOCOL_VERSION 14 -> 15, SUPPORTED extended; postcard round-trip
(open + closed shapes) and version-pin/ladder tests updated.

Producer: semantic_render::completion_popup_msg, the family pattern
(per-buffer cached-compare, active-buffer only, first-sight-closed
stays silent) with one new rule -- the session is WINDOW-stamped and
this state is per-frontend, so only the frontend whose own window
owns the session sees it open: a popup opened by TUI typing never
renders in an attached GPU and vice versa. Windowed rows share the
TUI overlay's POPUP_MAX_ROWS. Daemon-gated >= 15 (a v14 peer still
completes via the key round-trip, it just gets no GPU dropdown).

GPU consumption follows in this branch.

Levi Neuwirth 40ebdd8d7e feat(gpu): relative + hybrid line numbers over protocol v14 (sub-arc 3, GPU half)
Carry the line-number mode to the GPU so it renders relative/hybrid, not
just on/off. The v13 wire carried `LineNumbers { enabled: bool }`
(off/absolute only); v14 carries the full mode.

- Protocol: `LineNumberMode {Off, Absolute, Relative, Hybrid}` moves into
  pmacs-protocol (with `number_for`/`is_on`) so the wire, daemon, and both
  frontends share ONE enum and ONE number rule (Q#UX7); `pmacs` re-exports
  it as `crate:🪟:LineNumberMode`. `LineNumbers.enabled: bool` →
  `mode: LineNumberMode`. PROTOCOL_VERSION 13 → 14, SUPPORTED → [6..14],
  daemon-gated `< 14` (a v13 peer gets no LineNumbers, like the v10
  SearchPrompt bump).
- Producer (`line_numbers_msg`): ships the window's mode (cached-suppress
  on the mode now, seeded to Off).
- GPU: `line_numbers` field becomes the mode; `refresh_gutter_buffer`
  computes each number via `mode.number_for(line, cursor_line)` against the
  GPU's own cursor line (`cursor_line()` off `current_line_starts`). The
  buffer rebuilds every render, so relative numbers track the cursor for
  free. Gutter width unchanged (sized by line count → stable).

Tests: GPU headless render proves relative ≠ absolute with the cursor on
line 2; producer test asserts the mode ships; protocol version pins → 14.
fmt + clippy --all-targets clean both flavors + gpu; 1446 lib + 12 protocol
+ 55 pmacs-gpu tests pass. Needs a GPU eyeball.

Levi Neuwirth 1ea2d5f17f feat(gutter): daemon-owned line-number mode over protocol v13 (unified toggle)
Fix the control plane for the line-number gutter: M-x
window.toggle-line-numbers now works from EITHER frontend, each affecting
its own window.

Root cause (scores framing bet Q#UX1 false): rendering a gutter is
frontend-local, but the TOGGLE is a daemon command, so the mode has to
reach the GUI over the wire. My earlier GPU control (a --line-numbers flag)
left M-x-in-the-GUI a no-op and the two frontends' settings disconnected.

- Protocol: new additive `InstanceMessage::LineNumbers { buffer_id,
  enabled }`; PROTOCOL_VERSION 12 → 13, SUPPORTED grows to [6..13].
  Daemon-gated < 13 (a v12 peer keeps its gutter off), like every prior
  additive bump — no encoding break.
- Producer: SemanticRenderState::line_numbers_msg reads the frontend's
  active window mode (via active_window_for(frontend_id)) and emits on
  change; cached-compare suppression seeded to the frontend's `off`
  default, so a plain window adds zero traffic and existing frames are
  unchanged.
- Daemon: gate LineNumbers >= 13 in the write loop.
- TUI: drops LineNumbers silently (reads its window directly).
- GPU: consumes LineNumbers → drives local `line_numbers`; the
  --line-numbers flag retired.

Now the daemon Window.line_numbers is the single source of truth; both
frontends render locally from it.

Tests: line_numbers_msg emit-on-toggle/suppress-when-unchanged; protocol
version pins updated to 13. Validated: fmt + clippy --all-targets clean
both flavors; 1440 lib + 12 protocol + 53 pmacs-gpu tests pass.

Levi Neuwirth b9bd231e64 pmacs GPU minibuffer: wire v12 + band prompt + candidate dropdown (Q#MB1)
The pmacs-gpu frontend can now render the minibuffer, so M-x, C-x-prefixed
commands, and the LSP rename prompt work in the GUI. Render-only — the
minibuffer logic already lives in the core, which is untouched (its fields
are public, so the producer reads them directly).

Protocol v12 (additive; SUPPORTED = [6..12]):
- `InstanceMessage::MinibufferPrompt { prompt, input, cursor, candidates,
  selected, total }` — bufferless (the minibuffer is one global core
  instance), daemon-gated >= 12. The candidate list ships as a windowed
  slice (<= MB_VISIBLE = 10) around the selection, so a 1000-command M-x
  sends ~10 strings per keystroke, not 1000.

Producer / daemon / TUI:
- `semantic_render::minibuffer_prompt_msg` — cached-compare suppressed
  (a single value, not per-buffer), emitted from the active-buffer
  viewport. daemon gates the variant >= 12. The TUI ignores it (it paints
  the minibuffer via its own bottom row).

GPU:
- The bottom band shows `prompt + input` (ahead of search/status) with a
  band caret at the input cursor (monospace advance off the shaped band
  width); the buffer caret hides while a prompt is open.
- A vertical completion dropdown above the band — best match at top,
  selected row highlighted — via a third `TextRenderer` over bg quads
  (the menu popup pattern, reusing its colors). Only shows when there are
  candidates.
- `is_minibuffer_open_chord` forwards M-x and the C-x prefix (otherwise
  withheld) so the GUI can open a prompt / enter a prefix; the daemon then
  flips `dispatch_idle` false and the intercept gate round-trips the rest.
  (Also collapsed two unnested_or_patterns clippy nits in the chord
  helpers.)

Tests: candidate windowing, the producer (open M-x via Lua -> prompt +
windowed candidates -> cached-compare -> cancel clears), a v12 postcard
round-trip, and the version pin.

Levi Neuwirth 640b998d6b pmacs context menu: protocol v11 + dispatch + TUI/GPU surfaces (Q#CM1/Q#CM5)
The wiring that makes the menu and OS clipboard work end-to-end. The
protocol bump touches every exhaustive match on the wire enums, so the
daemon / frontend / GPU consumers all land together.

Protocol v11 (additive; SUPPORTED = [6..11]):
- `PointerKind::Context` (right-click), `FrontendEvent::MenuPointer`
  (GPU->daemon navigation, index-only), `InstanceMessage::MenuPrompt` +
  `MenuPromptRow` (daemon->GPU rows + highlight, daemon-gated >= 11).

Dispatch + producer:
- `EditorState`: menu interception in `dispatch_key`/`dispatch_mouse`,
  `MenuKey`, `dispatch_menu_key`/`_mouse`, `open_context_menu` (TUI) /
  `open_menu_at_byte` + `dispatch_menu_pointer` (GPU), `build_menu_rows`
  (calls the Lua resolver), `dispatch_idle` now false while a menu is
  open. `dispatch_pointer` gains the `Context` arm.
- daemon: routes `Context` -> open, `MenuPointer` -> navigate; gates
  `MenuPrompt` >= 11; drains the clipboard publish as
  `InstanceSignal::Clipboard`; honors the previously-dropped
  `FrontendEvent::Paste` (so paste works for the first time).
- `semantic_render`: `MenuPrompt` producer with cached-compare.

Frontends:
- TUI (`frontend.rs`): OSC 52 clipboard write; ignores `MenuPrompt`
  (the cell overlay renders the menu).
- GPU (`pmacs-gpu`): `arboard` dep; clipboard write/read + Ctrl-V inbound
  paste; right-click -> `Context`; `MenuLocal` + `MenuPrompt` handler;
  the popup (a second `TextRenderer` over bg quads) at the click pixel;
  hover/click -> `MenuPointer`; key intercept while open.

Also folds a pre-existing clippy `unnested_or_patterns` nit in a search
test (`Color::Indexed(11 | 3)`) that newer CI clippy surfaced.

Levi Neuwirth 6e47fb4725 regex-search: GUI regex prompt + protocol v10 (Q#RX5/RX6)
Carries regex mode to the GUI status band and lets the GUI start a
regex search.

SearchPrompt gains `regex` + `invalid` (protocol v10; SUPPORTED grows
to [6,7,8,9,10]). The fields changed that variant's encoding, so the
daemon's per-session gate moves from >= 9 to >= 10 — a v9 peer
negotiates v9 and is simply sent no SearchPrompt (the decorations
still highlight) rather than mis-decoding the wider shape. The
producer fills both from the active SearchSession.

GUI: `is_search_entry_chord` also forwards C-M-s / C-M-r (Ctrl+Alt) so
a regex search can start; M-r (the toggle) already round-trips via the
intercept path once a search runs. The status band reads
`Regex I-search:` in regex mode and `[invalid]` when the pattern won't
compile. Multi-line regex matches needed no GUI change —
push_glyph_extent_rects already fans a byte range across lines.

Tests: SearchPrompt postcard round-trip extended to regex/invalid
shapes; protocol version pin 9→10 + ladder grows to v10; GUI entry
chord accepts C-s/C-r and C-M-s/C-M-r. (last_search_prompt's 5-tuple
factored into a SearchPromptFacts alias to satisfy type_complexity.)

Levi Neuwirth 5111ae82e7 search: GPU isearch surface (Q#SR5, protocol v9)
Brings incremental search to pmacs-gpu, which has no minibuffer, by
reusing the shared daemon-side search core from the previous commit.

Key routing needs no new mechanism: `dispatch_idle` now also reports
false while a search is running, so the GPU's existing M11.6
optimistic-apply gate round-trips every keystroke to the daemon —
where `dispatch_search_key` extends the query / steps — instead of
self-inserting it. The match highlights were already wired (commit
2's SearchMatch / SearchMatchActive decoration colors), so they
light up live the moment keys round-trip.

The one thing a semantic frontend can't derive locally is the query
text, so a new additive `InstanceMessage::SearchPrompt { buffer_id,
query, active, total }` carries it (protocol v9, SUPPORTED grows to
[6,7,8,9]). The producer emits it cached-compare-suppressed like
StatusFacts — `query: Some` while searching, `None` to clear on
accept/cancel (matches keep highlighting via decorations), and
stays silent on a fresh buffer that never searched. The daemon's
per-session filter keeps the variant off wires negotiated < 9. The
GPU mirrors it into the status band: while searching, the band's
left side shows `I-search: <query> (n/m)` (or `[no match]`) in
place of the buffer name, returning to the name when the search
ends.

Tests: protocol version pin + SearchPrompt postcard round-trip
(active / failing / cleared shapes); producer emit-on-change +
suppress + clear-on-accept + first-sight silence; dispatch_idle
flips false during search (the GPU round-trip contract).

Levi Neuwirth 44430e8377 StatusFacts (protocol v8): name, modified, exact diag counts
The wire-authoritative half of the status band (Q#S1): an additive
InstanceMessage::StatusFacts { buffer_id, name, modified,
diag_errors, diag_warnings }, emitted by the semantic producer on
change (cached-compare). Counts freeze at their last value while
the diag store is stale — positions go wrong mid-edit but counts
merely lag, and flickering to zero per keystroke would be worse.
The daemon's write loop keeps the variant off wires negotiated
< 8, the DispatchIdle gate shape; SUPPORTED grows to [6, 7, 8].

GPU side: the band's left shows name + modified dot, the right
gains severity-colored E:n/W:n ahead of the local L:C/scroll
readout (rich-text spans, change-detected per side).

Levi Neuwirth 9528595c0e session M-1 — Pointer wire + daemon byte-space mouse semantics
Per docs/pmacs-gpu-mouse-framing.md (resolves the deferred Q#B5):
a pixel frontend cannot express the daemon's cell coordinates —
inline adornments shift visual columns invisibly to cell space and
the design contract forbids hit-test round trips — so the frontend
hit-tests locally and ships source-byte gestures.

- protocol v5: FrontendEvent::Pointer { buffer_id, byte, kind, mods }
  with PointerKind { Down, Drag, Up, DoubleDown }. Double-click
  detection is frontend-side (only it knows pixel proximity).
  SUPPORTED_PROTOCOL_VERSIONS gains 5; the send gate runs in the
  frontend (an older instance cannot decode the variant).
- daemon: dispatch_pointer replays the existing mouse gesture
  semantics in byte space against the semantic session's window —
  Down places + anchors, Drag grows, Up collapses an empty click,
  DoubleDown selects the word. Routed by the authenticated source
  (CrdtOp/Viewport trust rule); hit bytes clamp + snap to UTF-8
  boundaries (a hit can race an in-flight edit).
- word_range_at fix (pre-existing CUA bug the new test surfaced):
  double-clicking a word's FIRST character selected the previous
  word too — backward_word from pos sees the non-word char behind
  the hit and crosses over; walk from pos + ch_len instead.

Levi Neuwirth 4cd968bc0c B1 fix — align semantic frontend's window to its displayed buffer
Picks up the "arrow keys do nothing in the GUI" investigation. Root
cause is the multi-buffer mismatch the manual investigation theorized,
now confirmed in code and tested:

- `build_fresh_frontend_view` binds an attaching frontend's window to
  LOCAL's active buffer (a scratch the TUI never switched LOCAL away
  from).
- `send_buffer_snapshots` ships a snapshot per buffer in registry
  order; pmacs-gpu treats each as "switch visible buffer", so its
  `current_buffer_id` (and what it displays) becomes the LAST one — the
  file the TUI opened.
- So the GUI displays the file, but its daemon-side window edits the
  scratch. Arrow keys → `dispatch_key` → move the scratch cursor →
  `CursorByte { buffer_id: scratch }` → pmacs-gpu ignores it (its
  `current_buffer_id` is the file). The caret never tracks.

Fix: the `Viewport` event already declares which buffer the frontend
is displaying. The daemon now calls `align_semantic_window_to_buffer`
on it — re-pointing the semantic frontend's window at the declared
buffer (rebuild the cheap `TextView` line index, reset cursor; a
semantic frontend has no grid overlays to migrate, it renders from the
wire). Input and the `CursorByte` it produces then target the buffer
the user is actually looking at. The guard makes it a no-op when the
buffer is unchanged (so per-edit Viewport re-declarations don't reset
the cursor).

Tests:
- `viewport_aligns_semantic_window_to_displayed_buffer` — window
  starts on scratch, declares the file via align, a key then
  self-inserts into the *file*.
- `semantic_frontend_key_event_reaches_the_core` (from the prior
  commit) still green.

Also adds `PMACS_GPU_DEBUG_INPUT=1`: logs keys sent and each
`CursorByte` with `buf`/`current`/`match` so the displayed-vs-edited
buffer alignment is visible at a glance on retest.

Gates green: fmt; clippy --all-targets --workspace -D warnings
(default + crdt); pmacs lib 1334; crdt daemon tests 7; pmacs-gpu unit
18; m4_acceptance 88; m11_5_semantic_acceptance 2.

Still needs visual confirmation (arrow keys move the caret in a
running pmacs-gpu) before merge.

Levi Neuwirth 98ef140a84 B1 fix — route semantic-frontend Key events into the editor core
Visual validation found "nothing occurs" when typing in pmacs-gpu.
Root cause is daemon-side, not consumer-side: the dispatcher's
catch-all arm only called `apply_event` (→ `dispatch_key`) when the
source frontend had a `RenderState` — i.e. a grid frontend. A semantic
frontend like pmacs-gpu has only a `SemanticRenderState`, so its
`Key`/`Mouse`/etc. events hit the `else` branch and were silently
dropped (the long-standing "M11.5 scope" posture). So pmacs-gpu's keys
never reached the keymap; the cursor never moved.

This contradicts the Phase B framing's "consumer-only" claim: the
Explore fact-check verified `apply_event` → `dispatch_key` (true for
grid frontends) but not that the dispatcher gates that call on
`render_state`, so semantic-frontend keys never reach `apply_event`.
Exactly the gap visual validation exists to catch.

Fix: when the source has no `render_state` but is a registered
semantic session, route its input through a new
`apply_semantic_input_event` — `Key` → `dispatch_key`, `Mouse` →
`dispatch_mouse` — the same core path the TUI uses. No grid state is
needed (the editor core owns the cursor/buffer/commands); the
resulting motion/edit flows back to pmacs-gpu as `CursorByte` /
`CrdtOp`.

Regression test `semantic_frontend_key_event_reaches_the_core`: a
printable `Key` from a semantic frontend self-inserts and advances its
window cursor (0→1). Before the fix the dispatcher dropped it.

Gates green:
- cargo fmt --all -- --check
- cargo clippy --all-targets --workspace -- -D warnings (default + crdt)
- pmacs lib 1334; crdt daemon tests pass
- m4_acceptance 88, m11_5_semantic_acceptance (--features crdt) 2

Still awaiting visual confirmation (caret tracks arrow keys in a
running pmacs-gpu) before merge, per the framing's process rule.

T M11.9 — handle_remote_crdt_op fires buffer.after-edit (closes session-5 root cause) (#49)
Surfaced when PR #48's diag-store stale-flag turned out to have no
observable effect on session-5 validation: the wrong-position-color
artifact persisted even though the stale-flag suppression chain was
in place.

## Root cause (the *actual* one)

The M10.10 optimistic-apply layer routes plain-char keystrokes
(EOL-eligible, no Ctrl-modifier, etc.) as `FrontendEvent::CrdtOp`
rather than `FrontendEvent::Key`. The daemon dispatches CrdtOps via
`handle_remote_crdt_op`, which applies the buffer edit and queues
the op for broadcast — but **does not fire `buffer.after-edit`**.

`buffer.after-edit` was only fired by `dispatch_key` (editor.rs:506)
after a Key-path edit. The CrdtOp path bypassed it entirely.

The downstream LSP hook in `builtin/runtime/lsp.lua:379` calls
`pmacs.lsp.did_change` on every `buffer.after-edit`. With CrdtOp
edits not firing the hook, `did_change_full` (and therefore
`textDocument/didChange`) was never sent to clangd for the bulk of
typing activity. clangd's view of the document silently froze at
whatever state the last Key-path edit (find-file, keystrokes
through the minibuffer, modifier-combinations) had left it in.

Downstream symptoms, all silent:

- **Diagnostics frozen at pre-edit byte positions** — the
  session-5 visible artifact.
- **LSP semantic tokens stale** (for grammar-less languages where
  semantic_render uses LSP not tree-sitter — i.e. C++).
- **Inlay hints stale**.
- **Hover/go-to-definition/rename can return wrong-position
  results** if a CrdtOp edit moved positions since the last Key
  edit.

PR #47 (full=true on generation transition) and PR #48 (diag-store
stale-flag) were correctness fixes on the producer side, but they
depended on `did_change` actually firing to trigger their effects.
With did_change silenced, both were dormant for any CrdtOp edit.

## Fix

In `handle_remote_crdt_op`, when `edit_opt` is `Some` (the import
produced a text delta), after notifying views:

1. Set `active_frontend = source` so the hook's
   `pmacs.window.buffer()` resolves to the right buffer (matches
   the pattern `dispatch_key` uses).
2. Fire `buffer.after-edit` via `editor.lua_host.run_hook(...)`.

This makes the Lua observer chain (LSP `did_change` and any future
consumers) see CrdtOp-path edits identically to Key-path edits.

## Regression test

`daemon::tests::handle_remote_crdt_op_fires_after_edit_hook`
(crdt-gated):

1. Upgrade the active buffer to CRDT-backed
2. Install a Lua `buffer.after-edit` hook that bumps a global
3. Build a peer LoroDoc from the buffer snapshot, edit on the peer,
   export the op
4. Call `handle_remote_crdt_op` with the op
5. Assert the global counter is `1`

Pre-fix, the counter stays at `0`.

T M11.6 — DispatchIdle signal closes optimistic-apply blindness (#45)
The attach-mode optimistic-apply layer (M10.10) classifies any
plain-char keystroke as `Insert(c)` and applies it directly to the
local CRDT mirror, bypassing the daemon's keymap dispatcher. The
documented limitation ("the optimistic layer doesn't track keymap-
prefix state") also covered the minibuffer-active case, which
surfaced during session-5 manual validation: characters typed into a
`C-x C-f` prompt were optimistically inserted into the previously-
active document instead of routed to the minibuffer.

The fix is a daemon→frontend wire signal indicating whether the
daemon's *next* key event would be intercepted (minibuffer or pending
prefix) vs would self-insert. The frontend gates the optimistic-apply
path on this; when not idle, every keystroke round-trips as
`FrontendEvent::Key`.

Protocol changes (pmacs-protocol):

- `PROTOCOL_VERSION` 3 → 4; `SUPPORTED_PROTOCOL_VERSIONS` adds 4.
- New `InstanceMessage::DispatchIdle { idle: bool }`.

Daemon (`src/editor.rs`, `src/daemon.rs`):

- `EditorState::dispatch_idle()` — true iff `dispatcher.pending`
  empty AND `minibuffer.is_active() == false`.
- Per-tick emission: `last_dispatch_idle_sent: HashMap<FrontendId,
  bool>` tracks the last-broadcast value per session; emission fires
  on first frame after attach (absent entry) and on transitions.
- Gated on `crdt_replica` AND `negotiated_protocol_version >= 4` so
  older peers don't hard-error on the unknown variant. Same gating
  shape as the M10.5 CrdtOp and M11.1 SemanticFrame bumps.

Frontend (`src/attach.rs`):

- New `dispatch_idle: bool` (cfg `crdt`); default `false`
  (pessimistic — optimistic apply only activates after the daemon
  explicitly says idle).
- DispatchIdle messages consumed in the drain loop; they don't
  participate in `present_messages` batches.
- Optimistic-apply branch gated on `dispatch_idle`. When false, the
  branch returns false (forces fallthrough to the round-trip
  `forward_event` path).

Tests:

- `editor::tests::dispatch_idle_*` — fresh, prefix-pending, prefix-
  resolved, minibuffer-open/cancelled.
- `protocol::tests::dispatch_idle_round_trips_through_postcard` —
  wire encoding both polarities.
- `protocol::tests::protocol_version_is_four_for_dispatch_idle` +
  `supported_protocol_versions_includes_one_through_four` — pin the
  new version constants.

Gates: cargo fmt + clippy (workspace, with/without `crdt`) clean;
lib 1474 (+5 from 1469 baseline) with crdt; 1312 (+4) without;
m4 83; m11_5 (--features crdt) 2.

Acknowledged remaining gap: plain-char Lua bindings (e.g. binding
`q` to a command) still surface optimistic-apply divergence —
optimistic doesn't know "is this char bound to a non-self-insert
command in the current keymap." Rare in practice; revisit if anyone
hits it. Documented at session-5 finding time.

Levi Neuwirth efa8f6f8ed M11.3: Decorations projection (selection + diagnostics)
SemanticRenderState now also projects InstanceMessage::Decorations
from the instance-side state pmacs actually has.

- Selection: per-window byte-native state via active_window_for(fid)
  (SemanticRenderState now carries the session FrontendId), gated to
  the declared buffer and clipped to the viewport →
  DecorationKind::Selection.
- Diagnostics: the shared DiagnosticStore keyed by file URI. Made
  lsp::path_to_file_uri pub(crate) (byte-identical to the Lua
  file_uri_for) so the projection reproduces the exact store key from
  core.file_path. LSP (line,col) -> byte via a line-start scan
  against the buffer source; severity -> DiagnosticError/Warning/
  Info/Hint. Clipped to the viewport.
- StyleSpans and Decorations suppress unchanged frames independently
  (separate last_* maps): a selection move doesn't force a styling
  re-send and vice versa.
- Deliberately NOT emitted: SearchMatch/SearchMatchActive (no
  instance search-hit store), CurrentLine (frontend derives from
  CursorByte; emitting it would breach the contract boundary).
- InlineAdornments/BlockAdornments/FoldState remain unproduced by
  design — no inlay/blame/lens/fold/diff source exists in pmacs yet.
  Honest stubs (the M11.1 "declared, not yet wired" discipline), not
  empty messages every frame.

Dispatcher updated for SemanticRenderState::new(frontend_id). Lib
(1394 crdt / 1239 non-crdt) + integration green on both feature
flavors; clippy -D warnings clean on both.

Levi Neuwirth 4ba6fd7bb8 M11.2: semantic projection seam (SemanticRenderState)
The first real producer of the semantic-frontend arc. The instance
projects syntax styling to semantic_render sessions without
rasterizing to a cell grid.

- src/semantic_render.rs: SemanticRenderState, sibling of
  instance_render::RenderState. Reads the same EditorState, emits
  InstanceMessage::StyleSpans (tree-sitter spans via the active
  Theme), scoped + clipped to the FrontendEvent::Viewport byte range.
  Emits nothing until a viewport is declared; suppresses
  byte-identical frames (per-span delta encoding deferred to M11.4).
- CrdtState::version_scalar(): oplog version vector summed to a
  monotonic non-decreasing u64 — the StyleSpans.generation anchor.
- daemon dispatcher: semantic_states map parallel to render_states;
  projection selected per session. Semantic sessions get StyleSpans +
  CursorByte + BufferSnapshot + CrdtOp + presence, never CellDelta /
  grid Cursor. FrontendEvent::Viewport consumed (routed by
  authenticated source). SessionEstablished body extracted to
  handle_session_established (clippy 100-line ceiling). Grid-less
  sessions no longer panic the _ => apply_event arm.
- InstanceCapabilities default semantic_render flipped to
  cfg!(feature = "crdt") — the "M11.2 enables semantic" moment,
  analogous to the M10.8 Day-4 flip. M11.1 negotiation test comment
  updated for the flip (frontend-side default still false keeps M10.7
  outcomes unperturbed).

Lib (1392 crdt / 1237 non-crdt) + integration suites green on both
feature flavors; clippy -D warnings clean on both.
