Levi Neuwirth a118f0a3a2 fix(query-replace): pin the session to its origin buffer (wrong-buffer guard)
Review High (merge blocker): query-replace searched the origin buffer's
bytes but applied edits and moved the cursor through apply_active_edit /
search_place_cursor, which target whatever is ACTIVE. Focus can drift
mid-session — a click into another split, a key from another frontend,
both changing the active buffer outside the shadow — so a match found in
the origin buffer could be applied to an unrelated one. Buffer
corruption.

Fix: query_replace_on_origin() verifies the active buffer still equals
the session's origin buffer before every edit; on mismatch it ABORTS
without editing (clears the highlight, drops the session, status
'query-replace aborted: active buffer changed'), so an origin match can
never land in a foreign buffer. Guards replace/skip/all/replace-and-quit.
The dispatcher's after-edit revision compare now targets the ORIGIN
buffer (query_replace_origin_buffer + buffer_revision) not the active
one, so a drift-abort — which edits nothing — never spuriously fires
the hook. The forward-search clamp uses the origin bytes' length, not
active_buffer_len.

Also (review Low/med): query_replace_active() added to the
completion-popup modal-close guard, so a popup opened via the direct
Lua start (ed.query_replace_start) can't linger rendered-but-unreachable
while QR swallows keys.

Tests: core drift-abort (both buffers untouched) + end-to-end
focus-drift regression; ! fires after-edit exactly once for the batch;
RET/Esc/C-g quit paths (keep replacements); DEL skips. Acceptance
header corrected to match actual coverage.

Levi Neuwirth 7e7b3f2dcd feat(edit): query-replace (M-% / C-M-%) — Arc 2
Emacs query-replace, built on isearch with zero protocol change
(framing: docs/query-replace-framing.md).

- search.rs: find_first_from (literal) + find_first_regex_from (cached
  engine, zero-width-skip) + compile_search_regex (shared smart-case
  compile). Q#QR2's forward-scan-past-replacement primitive.
- QueryReplaceSession + core methods (editor_core.rs): begin (invalid
  regex refuses, Q#QR2), replace/skip/all/replace-and-quit/finish;
  matches run forward from next_from on the LIVE buffer, so offset
  shifts and never-re-matching-replacements (a->aa) fall out for free;
  current match highlighted via a single-element search_store set
  (SearchMatchActive, both frontends free) + cursor reveal; quit keeps
  replacements, only nothing-matched restores origin (Q#QR10).
- Dispatcher shadow (editor.rs): QueryReplaceKey (y/SPC, n/DEL, !, .,
  q/RET/Esc/C-g) + dispatch_query_replace_key, the 5th modal shadow;
  added to dispatch_idle disjunction (GPU round-trips keys) and fires
  buffer.after-edit itself (Q#QR1 — a shadow returns before the normal
  post-command check; once per !-batch).
- Lua: ed.query_replace_start/query_replace_active; query-replace /
  query-replace-regexp commands (chained minibuffer.read, separate
  from/to history buckets, empty-from reject / empty-to deletion);
  M-% / C-M-% bindings.
- Per-match prompt via core.status → v15 StatusFacts.message band.

Tests: 7 core unit + 11 dispatch_key acceptance (replace/skip/!/./quit,
nothing-matched restore, empty-to deletion, a->aa non-loop, regex incl
invalid, after-edit fires, dispatch_idle gate, explicit M-% AND C-M-%
binding tests) + 5 search unit.

Levi Neuwirth b25b47334d feat(panels): listview module, Q#P6 round-trip seam, references panel
Arc 1b phase 1 (framing: docs/lsp-panels-framing.md).

Q#P6 (the one Rust change): EditorCore.round_trip_buffers +
pmacs.buffer.set_round_trip_input(buf, on); dispatch_idle() reports
false while a marked buffer is active, so semantic frontends'
optimistic-apply stays off -- RET reaches a panel's buffer-local visit
binding instead of locally inserting a newline, and typing dispatches
into the edit path where the read-only intercept rejects it (a CRDT
import would bypass the intercept chain entirely). Pruned on kill.

Q#P1/P2/P3: builtin/runtime/listview.lua generalizes the *buffer-list*
idiom -- pmacs.listview.open{name, header, rows, on_visit, on_refresh}
owns ensure-buffer (recreates if user-killed), wholesale render with
bypass_intercept, line->item map, buffer-local RET/SPC/n/p/g/q keymap,
previous-buffer capture + q restore (never another panel; scratch
fallback), cursor re-seat after render, the read-only intercept, and
the Q#P6 mark. Panels are buffers: both frontends render them with
zero protocol change.

Q#P4: lsp.find-references (M-?) opens *references* -- one row per
location, paths shortened against the project root, RET visits via the
shared SP-4 template (jump ring, find_or_open, cursor walk; extracted
as visit_location for the phase-2 outline to reuse).

Acceptance: tests/listview_acceptance.rs -- open/seat/visit, header
non-visitable, q restore, read-only rejection, dispatch_idle gate,
refresh re-render + re-seat.

Levi Neuwirth 61a31b3ad4 fix(completion): address TUI-validation findings (LSP query gaps, scoping, prefix keys, window scope)
Five findings from the manual validation pass, all in-branch:

1. LSP-only words never queried the server: the auto-open path fired
   request_completion only when the sync providers already produced
   rows. An empty sweep now leaves a pending session and the request
   always fires; isIncomplete responses re-request on further typing.
   Corollary: attachment_for_request now flushes-if-attached but NEVER
   attaches -- the first cut wrapped attached_for_active, which spawns
   servers on demand, i.e. per-keystroke spawn attempts in unattached
   buffers (wedged the parallel m4 suite; serial ran 3x slower).
   Attachment stays buffer-open policy.

2. Cross-buffer LSP leak: the built-in provider's no-uri fallback was
   the legacy global store drain, so scratch/unattached buffers could
   show another file's cached completions. Strict now: no uri, no rows.

3. Pending prefixes own the keyboard: Action::Pending (C-x ...)
   dismisses the popup and the popup shadow is guarded on an empty
   dispatcher prefix, so the sequence's continuation and its C-g abort
   reach the dispatcher instead of the popup.

4. Window-scoped sessions: CompletionPopupState.window_id (stamped by
   completion_popup_open; Lua never sees it). Only the owning window's
   overlay paints -- same-buffer splits each carry a persistent
   overlay -- and a focus change invalidates the session.

5. Flaky worker test: the /proc thread-count probe and the idempotence
   check both build EditorStates and could run concurrently, polluting
   the baseline; merged into one test (non-Linux keeps a portable
   idempotence variant).

Regression tests for 1-4; framing doc gains the as-built notes.

Levi Neuwirth a1f5b1ffd7 fix(worker): deterministic pool teardown; EditorState::drop signals workers
Every EditorState leaked its entire worker pool (cores-1 threads, each
waking every 100ms): the Rc<AsyncRuntime> is cloned into dozens of Lua
closures, and registries those closures capture store mlua::Function
values -- reference cycles through the Lua VM that keep the Rc from
ever reaching zero, so WorkerPool::Drop never ran. Harmless for one
editor per process; in the m4 acceptance suite (54 editor-building
tests) it accumulated 1000+ live threads (observed: 60 complete
pmacs-worker-0..14 pools at once) plus ~9k spurious wakeups/second.

Fix: WorkerPool::signal_shutdown() -- set the shutdown flag + wake the
parkers from a shared reference; parked workers exit within their
100ms park timeout. Exposed as AsyncRuntime::shutdown_workers(), called
from a new impl Drop for EditorState. Deliberately signal-only, NO
join on the drop path: a worker can be blocked publishing its reply
onto the bus only the main thread drains, and a first cut that joined
in Drop deadlocked the m4 suite at teardown (fake-LSP tests wedged
2h+). WorkerPool::shutdown() (signal + join) remains for owners with
no bus consumer to deadlock against; Drop delegates to it as before.

Measured on the m4 suite: peak live threads 1026 -> 122.
Regression: tests/worker_shutdown_acceptance.rs (thread-count probe is
/proc-based, Linux-gated; the idempotence test runs everywhere).

Levi Neuwirth 53d771a935 feat(completion): Lua driver, popup bindings, LSP scoping + flush seams
Q#C1/C9: builtin/runtime/completion.lua reconstructs typing intent
from state (buffer.after-edit has no payload): a {buffer, cursor}
snapshot recognizes the single-byte-advance typing signature, so
paste/undo/kill/remote edits never auto-open; prefix >= 2 opens off
the synchronous providers, server trigger chars open a pending session
that materializes when the LSP answer lands; refresh-on-typing
re-derives the prefix from the text; a core-closed popup suppresses
reopen off the same edit (the accept case). completion.at-point on
C-M-i covers deliberate invocation; the driver filters collect() to
score >= 0 (collect keeps non-matches, merely sorted last).

Q#C8: CompletionContext gains uri; the built-in LSP provider scopes to
it (legacy global drain only when absent); Lua providers get uri as a
trailing ninth positional arg; context_for can now express char
triggers + uri. pmacs.lsp.attachment_for_request() exposes the
flushing accessor (attached_for_active) so completion requests answer
against current text, not the debounced didChange backlog.

Q#C2 write path: pmacs.completion.popup_show/popup_hide/popup_visible
publish into the core session (kind tags shared with collect() rows,
so driver code passes rows straight through).

Levi Neuwirth 361cc542c7 feat(completion): popup session store, self-positioning view, dispatcher shadow
Q#C2: CompletionPopupState (buffer + byte anchor + prefix + candidates
+ selection) behind SharedCompletionPopup on EditorCore — the
completion twin of SharedMenu. Q#C4: CompletionView reworked from the
dormant M4.7 store-keyed full-viewport painter into a self-positioning
overlay (MenuView model): windows candidates around the selection,
maps the byte anchor to a screen cell via the diag-view walk, places
below the anchor row (flips above when nothing fits), self-suppresses
when closed or on a foreign buffer. Q#C3: dispatch_key gains a PARTIAL
shadow — only TAB/RET/C-n/C-p/Up/Down/Esc/C-g intercept while the
popup is open; everything else falls through so typing keeps
self-inserting, with post-dispatch validation (active buffer, cursor
at/after anchor, word bytes between) closing broken sessions after the
after-edit hook has had its chance to refresh. Q#C7: accept
re-validates at the moment of accept and applies a single Replace
(one undo step; empty-prefix trigger sessions degrade to Insert),
firing buffer.after-edit through the existing revision check.

Framing: docs/in-buffer-completion-framing.md. Lua driver + bindings
follow in this branch.

Levi Neuwirth 9ae381f740 feat(tui): relative + hybrid line-number modes (sub-arc 3, TUI half)
Extend the gutter with the last two of the framed modes (Q#UX4):
- Relative: each line shows its distance from the cursor line (cursor = 0).
- Hybrid: cursor line shows its absolute number, others relative
  (Vim number + relativenumber).

`LineNumberMode` gains `Relative`/`Hybrid` + `number_for(line, cursor_line)`
(the per-line displayed value) and `is_on()`. `paint_line_number_gutter`
now derives each number from the mode and the cursor's buffer line
(`text_view.line_at_offset(cursor)`); the TUI re-renders the whole frame on
cursor motion, so relative numbers track the cursor for free. Gutter width
is sized by `digits(line_count)` for every on-mode, so the text never
jitters as the cursor moves.

Mode selection (chosen over a 4-way cycle): `window.toggle-line-numbers`
stays a binary off/absolute toggle; a new `window.set-line-numbers` opens
the minibuffer with an arrow-navigable completion dropdown
(off|absolute|relative|hybrid) to pick a mode directly. `set_line_numbers`
accepts all four; the getter returns them.

No protocol change here — the GPU half (which needs the mode over the wire,
protocol v14) follows. Test: number_for across all modes. fmt + clippy
clean both flavors; 1446 lib tests pass. Needs a TUI eyeball.

Levi Neuwirth 9d7a48a844 fix(minibuffer): arrow keys navigate the completion dropdown
The Up/Down arrows were hardwired to command *history*
(`from_chord`: `Up => HistoryPrev`, `Down => HistoryNext`), so with a
completion dropdown showing they never moved the highlight — only M-n/M-p
scrolled candidates. Pressing Up/Down (the intuitive way) left the
selection stuck, which read as a stuck highlight bar in the GPU minibuffer.

Now Up/Down resolve contextually in the dispatcher (which, unlike the
static `from_chord`, sees the session): when a dropdown is showing they
navigate candidates (`scroll_candidate ∓1`), otherwise they step through
history. C-p/C-n stay pure history; M-n/M-p stay pure scroll. Daemon-side,
so both frontends benefit.

- new `MinibufferAction::{Prev,Next}CandidateOrHistory` (Up/Down); resolved
  in `dispatch_minibuffer_key` via `Minibuffer::has_candidates`.

Tests: `from_chord` maps the arrows to the new actions; an end-to-end
editor test opens M-x and asserts Down/Up move the completion selection.
fmt + clippy clean both flavors; 1445 lib tests pass.

Levi Neuwirth c1122691ad feat(tui): diagnostic gutter signs riding the line-number gutter (sub-arc 2)
Sub-arc 2 of the UX arc, TUI half. When a window reserves a line-number
gutter, lines with diagnostics get a severity-colored sign glyph (E/W/I/H)
in the gutter's leading column — closing the last deferred Task #23 item.
No protocol/daemon change: the per-line severity is already frontend-side
(the diag store the DiagnosticView already reads).

- `Viewport` gains `gutter_w` so overlays can reach the gutter's leading
  column at `cell_origin.col - gutter_w`; the text area is already shifted
  past it, so viewport-relative painters stay gutter-agnostic.
- The gutter's number pass now runs *before* the overlays (was after), so
  the DiagnosticView can draw its sign into the gutter's blanked leading
  column without the number pass erasing it.
- DiagnosticView: with a gutter, draw the severity sign glyph colored by
  `underline_color()`; without one, keep the legacy column-0 background
  marker (the "fake gutter" that predates a real gutter column). Extracted
  to `paint_line_markers` to keep `render` under the line cap.

The number never reaches column 0 (>=1 leading pad by construction), so
sign and number coexist. Diagnostic signs currently ride the line-number
gutter (visible when line numbers are on); a signs-without-numbers mode is
deferred.

Test: gutter_sign_replaces_the_column_marker_when_a_gutter_is_reserved.
Validated: fmt + clippy --all-targets clean both flavors; 1441 lib + 22
diag tests pass. Needs a TUI eyeball before the GPU half.

Levi Neuwirth fae7ed3fd0 feat(tui): line-number gutter (UX arc sub-arc 1, TUI half)
Introduce a reserved left gutter column with absolute line numbers in the
TUI/grid frontend — the foundational piece of the UX arc (docs/ux-arc-
framing.md). Default OFF (Emacs tradition), so zero layout/coordinate
change until a window opts in.

- window.rs: LineNumberMode { Off, Absolute } + per-window `line_numbers`
  field + `gutter_width()` (digits(line_count) + PAD) + `decimal_digits`.
- editor.rs: the gutter is one viewport shift at the paint site
  (cell_origin.col += gutter_w, cell_size.cols -= gutter_w) — every
  viewport-relative painter (text, syntax, diag underline, search) stays
  gutter-agnostic. The sites that read rect.origin.col directly get a
  manual +gutter_w: cursor placement, local selection, mouse hit-test
  (a gutter click maps to line start, Q#UX6). paint_line_number_gutter
  writes right-aligned dim digits alloc-free.
- overlay_paint.rs: remote-presence cursor/selection shift by gutter_w.
- Lua: pmacs.window.set_line_numbers/line_numbers +
  window.toggle-line-numbers command.

No protocol/daemon change (frontend-local, Q#UX1). Tests: gutter render
(right-aligned digits + past-EOF blanks) + decimal_digits.

Validated: fmt clean; clippy --lib clean both flavors; 1439 lib tests pass
both flavors. Needs a human eyeball (coordinate-math change) before the PR.

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 7723f51f12 regex-search: TUI regex mode + multi-line wash (Q#RX3/RX4/RX5)
Wires regex matching into the search session and the terminal
frontend.

SearchSession gains `regex` and `invalid` flags. search_begin takes a
`regex` argument; recompute dispatches find_all_regex (regex) vs
find_all (literal), recording `invalid` when the pattern won't
compile (an invalid pattern clears the matches and shows [invalid]
rather than a stale count). search_toggle_regex flips the mode and
re-runs the current query.

Input: C-M-s / C-M-r start a regex search (search.forward-regex /
search.backward-regex commands → ed.search_start(forward, regex)).
M-r toggles literal <-> regex mid-search — a new SearchKey decoded in
dispatch_search_key, so it works the same in both frontends (the GUI
already round-trips every key while searching). The TUI prompt reads
"Regex I-search:" in regex mode and "[invalid]" when the pattern
won't compile.

Multi-line: SearchView now washes each row a match spans, mirroring
paint_local_selection's per-row clip (newline excluded so a spanning
match doesn't paint a phantom trailing cell). Single-line matches —
every literal match — touch exactly one row, unchanged. The GPU
already fans multi-line ranges per-line, so it needs no change here.

Tests: regex match / smart-case / invalid-flags-and-recovers /
toggle-reinterprets-query (core); C-M-s starts regex + M-r toggles
mid-search (dispatch); multi-line per-row wash (SearchView render).

Levi Neuwirth 22773737e9 search: attach the TUI match-wash overlay so isearch is visible
Fix for "seems to only search for the first character." The TUI's
`SearchView` overlay was written (commit 2) but never attached to a
window, so the terminal frontend painted no match highlights — the
only feedback was the cursor jumping to the first match, which made
refining the query past the first character look like a no-op even
though the search was working (verified: the query accumulates
correctly through the full run-loop path).

`search_begin` now attaches a `SearchView` to the active window
(deduped by overlay kind, so repeat searches don't stack it). The
view self-suppresses when the store has no matches or is stale, so a
persistent attach is safe — it paints only while a search has live
matches and stops the moment an edit invalidates them.

`SearchView` now keys on the *rendered* buffer (`Buffer::id`) instead
of a fixed id captured at construction, so one attached instance
keeps highlighting correctly even if the window later switches
buffers (the store is per-buffer; a buffer with no entry paints
nothing).

Tests: a render-level test that paints a real frame mid-search and
asserts both the match wash (bright `Indexed(11)` on the active
match) and the full `I-search: foo` prompt land on the grid — the
coverage that was missing, which would have caught the unattached
overlay. Plus a run-loop-fidelity test (renders interleaved with
keystrokes) pinning that the query accumulates rather than sticking
at the first character.

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 58b68f6ac0 search: TUI incremental isearch input (Q#SR5)
Wires the live-typing half of in-buffer search for the terminal
frontend, on a frontend-agnostic core so the GPU (next commit) can
share it.

EditorCore gains a `search: Option<SearchSession>` (query + origin
cursor + direction) and the `search_*` methods that drive it:
begin records the origin, input_char/backspace re-run `find_all`
against the origin buffer and refocus the match nearest the origin
(failing searches anchor the cursor back at the origin), step walks
the store's active match (wrapping, also usable post-accept), and
finish either keeps the cursor + matches (accept) or restores the
origin and clears them (cancel). The matches live in the shared
`search_store`, so the decorations producer and the TUI SearchView
light up live as you type.

Input routing is intercepted in `EditorState::dispatch_key`: while
a search runs, every key flows through `dispatch_search_key`
(SearchKey::from_chord) instead of the global keymap — printable
chars extend the query, C-s/C-r (and Down/Up) step, RET accepts,
C-g/Esc cancel, BS shortens. This is the same dispatch path the
daemon's `FrontendEvent::Key` round-trip uses, so the daemon-side
search already works; the GPU just needs to route keys + show the
prompt (commit 4). The TUI paints an `I-search: <query> (n/m)`
prompt on the bottom row while keeping the terminal cursor in the
buffer at the active match.

C-s / C-r start the search (search.forward / search.backward Lua
commands → ed.search_start). Both keys were free in the default
map (save is C-x C-s, redo is C-x r), so isearch lands without
disturbing the CUA / Emacs editing keys — no cursor.right rebind
needed (the framing doc had flagged C-f for veto; C-s is cleaner
and Emacs-faithful).

Any edit now marks the buffer's matches stale in apply_active_edit
(M11.8), closing the headline "stale-after-edit linger" bet:
accepted highlights vanish the moment the text they described
changes, rather than painting at wrong offsets.

Tests: EditorCore-level (begin/type/step/wrap/focus-from-origin/
cancel/accept/backspace/smart-case/stale-on-edit) and dispatch-
level acceptance (C-s drives the whole loop; Esc restores; query
keys never self-insert).

Levi Neuwirth a358df8cf2 triple-click selects the line (Q#M4, protocol v7)
PointerKind::TripleDown — the cheap additive bump shape returns:
PROTOCOL_VERSION 7, SUPPORTED [6, 7], the new variant kept off
pre-v7 wires by a frontend send-gate that downgrades it to the
plain Down a third click produced before. The GPU's click history
deepens to a chain count (1 → Down, 2 → DoubleDown, 3 →
TripleDown, then restart). Daemon side, select_line_at_cursor
selects the line including its trailing newline, so consecutive
triple-click lines abut.

Levi Neuwirth e8e494e1c1 Shift-click extends the selection (Q#M5)
dispatch_pointer consults the mods it has carried since v5: a Down
with SHIFT keeps the existing anchor (or, with no selection,
anchors at the pre-click cursor) and only moves the cursor — the
universal extend convention. Zero wire change. Frontend-side, a
Shift-click neither advances nor inherits the multi-click chain,
so two Shift-clicks can't become a word select.

Levi Neuwirth 98fb6bb7a4 fix: paint_frame deadlock — diag-store lock held across overlay render
The mode-line counts (a0bd4d7) took the diag-store mutex before the
window loop and held it through overlay rendering. DiagnosticView —
attached as a window overlay the moment a file with an LSP opens —
locks the same mutex in its render, and std's Mutex is not
reentrant: the daemon's main loop deadlocked on the first frame
after C-x C-f, unresponsive even to SIGINT (parked in futex_wait,
confirmed on the live process). No render test attached a
diagnostic overlay, which is how it slipped through.

The lock is now scoped to the per-window summary computation, after
overlays have rendered and released it. Regression test renders the
full paint_frame path with a real DiagnosticView attached.

Levi Neuwirth a0bd4d7f6c mode line: per-buffer diagnostic counts (E:n W:n)
M4.6 follow-up piece 1: the mode line's right segment now shows
error/warning counts for the window's buffer, computed from the
shared diag store at paint time. Counts are suppressed while the
URI's diagnostics are stale (mid-edit, pre-publish) so the readout
never describes text that no longer exists. Info/hint severities
stay off the mode line.

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 bd728c4705 CUA region semantics — shift selection, region-aware delete + type-over
- S-<arrows>/S-<home>/S-<end> (+C-S word/paragraph variants) extend a
  selection; the TUI grid paints it reverse-video; double-click
  selects the word at point.
- Backspace / Delete consume the active region (delete_region first,
  falling back to single-codepoint semantics).
- Typing replaces the region: buffer.self-insert / newline / tab
  delete_region before inserting. pmacs-gpu cooperates by
  round-tripping keys while an own-window selection is active, so
  the region-aware commands run instead of a raw optimistic op.
- tests/cua_region_acceptance.rs drives the real dispatch path:
  select -> BS/DEL/char/Enter, plus the no-region fallbacks.

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 c660d55881 M_B1: LspStyleView — LSP-driven syntax coloring in the TUI
Closes the visible "C++ has no syntax coloring in the grid TUI" gap.
Sibling of SyntaxHighlightView: a View impl that paints LSP semantic
tokens as cell styles, attached for buffers with no bundled
tree-sitter grammar. Same policy A (one styling authority per buffer)
the semantic-frontend producer arc enforces, applied to the grid
renderer the user actually uses today.

Mechanics: every render re-derives the buffer's URI from
buf.file_path() and pulls (encoding, legend) via the existing
LspManager::semantic_style_context plus tokens via for_uri. Per
visible line, tokens are converted from LSP encoding units to byte
ranges via char_to_byte, then to display columns via the existing
byte_range_to_display_cols (UTF-8 + tab aware). Theme::lookup
resolves token type names through the same dotted-prefix mechanism
the tree-sitter capture names use, so "function", "variable",
"type", "keyword" land on the existing theme vocabulary with no new
style names. Default-styled spans skip the per-cell loop, matching
SyntaxHighlightView's short-circuit.

Wiring: pmacs.lsp._attach_style binding pushes the overlay on the
active window (mirrors pmacs.parse._attach_highlight). install_lsp
and make_lsp_manager take SharedSyntaxRegistry so the binding can
hand the LspStyleView the shared ThemeHandle; editor.rs caller
updated. builtin/runtime/lsp.lua's attach_buffer attaches the view
when pmacs.parse.language_for_path returns nil (grammar-less
signal), dedup'd via a styled_buffers set that mirrors syntax.lua's
highlighted_buffers.

Test: lsp_style_view_paints_cells_from_semantic_tokens — seeds an
Initialized fake LSP client (using the cfg(test) helper from the
producer arc) on a /tmp/x.cpp buffer with one token, asserts the
expected cells are styled per the theme face and the cell just past
the token range is unchanged.

Levi Neuwirth f7267cd720 T M4.5 L1: cross-file nav foundations — per-buffer file_path, jump ring, x-file go-to-def
Lays the groundwork for WorkspaceEdit/rename (L2+) by making
navigation cross-file-correct.

- Relocate file_path/file_meta from the EditorCore global onto
  Buffer itself, so each buffer keeps its own filesystem identity
  across cross-file navigation. Accessors + registry/editor/lua/
  semantic_render call sites migrated; zero behavioural change for
  single-file flows.
- uri->path: project_index::uri_to_path made pub; pmacs.lsp.path_for_uri.
- find-or-open: BufferRegistry::find_by_path + pmacs.buffer.find_or_open
  dedups an already-open file instead of spawning a duplicate buffer
  (SP-4 Gap A).
- Bounded jump ring on EditorCore (cap 64, oldest-evict, stale-buffer
  skip): push_jump/jump_back + pmacs.editor.* bindings + lsp.jump-back
  command bound to M-,.
- pmacs.lsp.go_to_definition cross-file branch: decode URI ->
  push_jump -> find_or_open -> reposition, with a failure path that
  unwinds the pushed origin. ensure_server now passes cfg.env through.

Tests: 5 jump-ring unit tests; m4_12_cross_file_go_to_definition_and_
jump_back end-to-end via a new `defenv` fake-LSP mode. All gates green
(lib 1262/0, m4 67/0, m8_1/m8_9/m8_10, m9_1, m11_5 --features crdt 2/0).

Levi Neuwirth 0201943c97 T M4.5 frame-loop reorder: tick_async last (1-frame LSP await latency)
The async bridge settles awaiters inside `tick_lsp`/`tick_mcp` by
posting to the message bus; `tick_async` drains that bus and resumes
the parked coroutine. With `tick_async` running *first* (historical
accretion from M3.3, predating processes/LSP/MCP), every LSP/MCP
`:await()` resumption was deferred a full frame: the response
absorbed in frame N's `tick_lsp` wasn't observed until frame N+1's
`tick_async` (~33ms structural floor @ 60Hz, plus a render frame).

Reordering both production loops (`editor::run` and the daemon loop)
to `processes → lsp → mcp → async` makes settle→resume happen in the
same frame, halving the floor to one frame. The only documented
ordering invariant — `tick_processes → tick_lsp → tick_mcp` for
same-batch supervisor I/O — is preserved; settle (bus post) and
resume (bus drain) are bus-decoupled, so the move cannot regress
correctness in either direction.

Acceptance tests open-code their own per-test tick orders and never
drive `editor::run`, so none covered production ordering. Added
`m4_5_await_resolves_same_frame_as_response_absorbed`, which drives
the exact production order and asserts the awaited request resolves
in the same frame its response is absorbed (absorbed_cycle ==
done_cycle); it fails if anyone reverts to `tick_async`-first.

Gate: fmt clean; clippy --all-targets -D warnings clean; lib
1223/0; m4_acceptance 59/0; m9_1 18/0; m8_1/m8_9/m8_10 green

Levi Neuwirth ad530a5beb T M4.5 async bridge: LSP requests settle async-runtime jobs
Replaces the editor-blocking `poll_until` tick-loop in the LSP UX
with the M9.1 external-settle pattern: each `textDocument/*` request
registers a pending entry via `AsyncRuntime::register_external` and
returns the job id; the JSON-RPC response (or a server-teardown /
cancel / timeout) settles it, resuming a `Handle:await()` coroutine.
No worker thread is occupied for the round-trip.

Hybrid result delivery (operator decision): the response is absorbed
into the typed stores *and* carried through the Handle. The
completion popup and diagnostics gutter keep reading the stores
untouched; request/response command code awaits the value directly.

Core (src/lsp.rs):
- `LspManager` gains `runtime: SharedAsyncRuntime` (threaded through
  `make_lsp_manager` / editor.rs, mirroring `make_mcp_manager`) plus
  a `(server, request_id)` -> PendingExternal awaiter table parallel
  to `pending_routes`.
- `request_*` return the async `JobId` (`= u64`, signature
  unchanged; no caller consumed the old JSON-RPC id).
- `handle_response` settles every non-cancelled awaiter ok/failed
  alongside store absorption; null result still wakes await with nil.
- Awaiters drain-cancelled at all three `pending_routes` purge sites
  (restart generation flip / terminal exit / forget) so a coroutine
  cannot park on a server that went away.
- Per-tick sweep: per-awaiter cancellation (Handle:cancel() or
  supersede via a stable `lsp:{method}:{sid}:{uri}` key), with
  `$/cancelRequest` + `cancelled_rids` on abandonment to drop the
  cancel/response race silently. Mirrors mcp.rs.
- Per-request timeout (default 10s, `pmacs.lsp.set_request_timeout_ms`):
  an alive-but-silent server fails the await instead of hanging.

Lua surface:
- `_request_*_raw` job-id bindings (mirror `pmacs.mcp._send_request_raw`).
- builtin/runtime/lsp.lua: Handle wrappers + the four commands
  rewritten to spawn `pmacs.async` coroutines that `:await()`;
  `poll_until` removed. Server-gone / error surface as structured
  await failures in the modeline.

Tests:
- pmacs_fake_lsp: `error` / `silent` modes for deterministic
  failure-path coverage.
- 5 end-to-end await-path tests (success+store, server-error->failed,
  server-stop->cancelled, timeout->failed, supersede->cancelled).

Gate: fmt clean; clippy --all-targets -D warnings clean; lib
1223/0; m4_acceptance 58/0; m9_1_acceptance 18/0 (MCP unaffected).

Levi Neuwirth c50db222d3 V0.2-prerequisite pull-forward + M10.11 clean audit round
Pulls a set of planned V0.2 prerequisites forward to ship in v1.0,
plus the clean audit-review round over that work.

V0.2-prereq implementations (documented promotions, not M11
surprises; operator raised the v1.0 public-API ceiling to absorb
them — see V0.2-PREREQUISITES.md "v1.0 pull-forward"):

- CC-1: `bypass_intercept` opts on buffer insert/delete/replace —
  skips the Lua intercept chain only; preserves the same-buffer
  re-entry guard, undo/dirty bookkeeping, view notifications, and
  CRDT broadcast queueing.
- CC-2: `pmacs.buffer.on_removed(buf, cb)` + idempotent `:remove()`
  handle; buffer-local keymaps pruned on removal. Fires for both
  `pmacs.buffer.remove` and `.kill` (incl. interactive C-x k);
  callback errors logged to *errors* without failing the removal.
- SP-4: `pmacs.buffer.from_file`.
- SP-5: `pmacs.fs.watch` (polling; `:cancel()`/`:is_cancelled()`).
- SP-7: `pmacs.async.yield_to_next_tick` (worker-free next-tick
  yield); outline-aggregate repaint now uses it instead of
  workers.sleep(0):await(), pinning propagation to one async tick.
- SP-1: `pmacs.editor.move_to_line` (0-based, clamps out-of-range).
- SP-6: `pmacs.outline.query` published by pmacs-outline.
- SP-3: audit rule 15 `reach-around-require-field` (Info).
- CC-3: runtime API-availability documented (docs-only).

Clean audit-review round (M10.11 framing stop-condition pass):

- Finding 1 (fixed): clippy needless_raw_string_hashes blocked
  `clippy -D warnings` on both lanes; raw-string delimiter fixed.
- Finding 2 (fixed): fs_watch acceptance test was racy — the
  `pending == 1` gate could not distinguish the in-flight baseline
  stat from the steady-state poll sleep, so under load the mutation
  raced the baseline (~1/3 fail in the default lane). Rewritten to
  re-emit a distinct change each pump iteration; 6/6 on the
  previously-failing invocation.
- Finding 3 (fixed): documented fs.watch's async-baseline startup
  window and size+mtime-granularity detection limit.
- Finding 4 / SP-8 (logged, non-blocking, out of diff): a
  pre-existing PTY-lifecycle test timing flake under severe CPU
  oversubscription; src/process.rs untouched here.

CC-1's opts-extension-counts question resolved explicitly
(consistent treatment: counted; ceiling raised to fit).

Gate at normal load, both lanes: fmt clean; clippy --all-targets
-D warnings clean; non-crdt lib 1223/0; crdt lib 1377/0;
m8_1/m8_9/m8_10 green.

Not in scope here: v1.0 CHANGELOG body, version bump, the M10.11
Finding-4 (reattach undo) user-facing artifact, and the recorded
two-laptop manual acceptance — tracked as the remaining v1.0 steps.

.gitignore: M*-FRAMING.md added to the internal-only block for
consistency with the M*-AUDIT.md / M*-SHIP-GATE.md siblings.

Levi Neuwirth 45be65b026 M10.10 ship gate
Land the optimistic local-edit-application layer on top of the M10 CRDT
foundation: frontend-side rope replica with local edit application,
daemon-authoritative broadcast, and bidirectional cursor reconciliation.
Keystrokes feel instantaneous because the local replica answers next-render
queries before the daemon round-trip completes, while the daemon remains
the single source of truth for conflict resolution and broadcast to remote
replicas.

Architecture beats:
- BufferMirror (src/buffer_mirror.rs) holds a per-frontend rope replica
  with explicit cursor-staleness tracking. Every event that may move the
  active cursor or swap the active buffer marks the mirror stale; the
  next CursorByte from the daemon clears it.
- CrdtOpOrigin {OptimisticReplica(FrontendId), DaemonKey} routes broadcast.
  OptimisticReplica skips re-application on the originating frontend
  (already applied locally); DaemonKey broadcasts to all replicas including
  source -- covers Lua-driven and generated-buffer edits that bypass the
  optimistic path.
- Generated buffers (*help*, *workers*, *pmacs-instance*, *errors*) funnel
  apply_edit output through queue_daemon_origin_crdt_op so post-attach
  CRDT upgrades don't drop their edits.
- forbid(unsafe_code) preserved throughout; loro 1.12 added as the CRDT
  engine.

Audit posture: M10.10 shipped through six post-audit review rounds with
twenty-eight cumulative findings, most categorized as "incomplete
application of a prior round's mechanism." The audit doc records
grep-driven exhaustiveness as the standing countermeasure.

Levi Neuwirth 587a2a15de M9 ship gate
Land the Model Context Protocol (MCP) integration as a transport binding,
not a built-in feature. Six Lua functions plus userdata methods expose
the substance of three MCP feature areas (resources, tools, prompts), a
notification dispatcher, and a non-trivial AI-assistance example package
that meets the architectural ship gate (spec/pmacs-spec.tex:1572): zero
direct calls into the Rust core, zero special-cased MCP handling outside
the public API, source under 2000 lines of Lua.

The M9.5 -> M9.6 -> M9.7 -> M9.8 layered composition validates the claim
"AI is a transport binding, not a feature" -- pmacs-mcp-ai composes with
pmacs-mcp-prompts.render and inherits notification handling transitively
through M9.7's package, demonstrating that the AI domain is a layer
above MCP, not a thread woven through the core.

Subtask shape:
  M9.1 stdio transport + initialize handshake + restart policy
  M9.2 resources with in-flight + settled cache and per-uri invalidation
  M9.3 tools with isError-vs-JSON-RPC-error semantics + cancellation
  M9.4 prompts with required-argument validation
  M9.5 notification dispatcher (on_notification, off_notification)
  M9.6 tools-as-commands fixture package + 12 audit findings disposed
  M9.7 prompts-as-result-buffers fixture package + tree-sitter-md grammar
  M9.8 AI-assistance fixture package (363+ LoC; 17/17 acceptance tests)
  M9.9 formal package audit -- PASS on all three criteria
  M9.10 release: TRANSITION-M9.md + MCP-for-package-authors guide
