Adds `arborium-lean` 2.18 and one `BUILTIN_LANGUAGES` entry, closing the
framing's open verification obligation on the crate choice.
Why this crate and not `tree-sitter-lean4` (Q#LN1): the latter depends on
`tree-sitter = "0.25"` directly rather than the shared
`tree-sitter-language` ABI crate, and `^0.25` excludes our 0.26, so it
would fork the graph exactly as the dead `tree-sitter-dockerfile` does.
It also exports only `pub fn language()` while its README advertises a
`LANGUAGE` const that does not exist, and its package `include` omits
`queries/` so it ships no highlights at all. `arborium-lean` uses
`tree-sitter-language 0.1` as its sole runtime dep, ships a pre-generated
ABI-15 parser plus scanner, and exports real query constants.
`cargo tree -d` reports no duplicate `tree-sitter`.
The entry is named `lean4`, not `lean` (Q#LN2): `ensure_server` passes
`LanguageEntry.name` through as the `didOpen` language_id, and the Lean
ecosystem's id is `lean4` -- `lean` is Lean 3, which is end-of-life. It
claims `.lean` only; `.olean` is a compiled binary and `.ilean` is JSON
metadata (Q#LN3).
Four tests. The load-bearing one is `lean4_grammar_loads_and_parses`,
which discharges the half of Q#LN1 that could not be settled by reading:
`arborium-lean` exports `const fn language() -> LanguageFn` rather than
the `LANGUAGE` const every other entry uses, and its README demonstrates
usage against a patched tree-sitter core. Neither is supposed to matter,
but "supposed to" is not evidence. The fixture parses without error, and
-- the part that actually guards a misbuild -- its Unicode operators
produce structure rather than degrading silently: the grammar must see a
`(arrow)` for the arrow, a `(forall)` for the universal quantifier, and a
`(comparison)` for the inequality.
The error-free claim is deliberately scoped to the committed fixture.
Lean's syntax is user-extensible via macros, so a static grammar
mis-parses some legal input by construction; the framing scores that as
bet 3 rather than the doc overselling it.

Register `html` (.html/.htm/.xhtml) and `css` (.css) entries in
BUILTIN_LANGUAGES, backed by the official tree-sitter-html 0.23 and
tree-sitter-css 0.25 grammars over the tree-sitter-language shim (ABI-fine, no
overlay — both export their query constants). The single `extensions` field
wires detection ahead of the LSP filetype map.
HTML's crate-exported INJECTIONS_QUERY lights up <script> -> javascript
(already registered) and <style> -> css (registered here) via the #122
injection engine — the north-star injection consumer.
The only capture reconciliation (Q#WEB4): the two web captures both grammars'
queries use that pmacs did not recognize — ("tag", fg(5)) and
("attribute", fg(3)) — added to highlight.rs's table; @tag.error prefix-walks
to tag, and everything else already maps.
Tests: table guards; load-and-parse smokes (roots document/stylesheet);
highlights-resolve (node-name compat gate, asserts @tag present); extension
resolution; a tag+attribute paint test (the attribute assertion is
load-bearing); and the injection payoff — an HTML buffer with embedded
<style>/<script> paints a CSS property and a JS keyword INSIDE the injected
regions.

Register a `latex` entry in BUILTIN_LANGUAGES (.tex/.latex/.sty/.cls) backed by
codebook-tree-sitter-latex 0.6.1 — the linkable republish of latex-lsp's grammar
over the tree-sitter-language shim (the squatted `tree-sitter-latex` 0.1.0 ships
no scanner.c and cannot link). The single `extensions` field wires the whole
detection chain ahead of the LSP filetype map, so no Lua edit is needed.
The crate exports no query constants, so highlighting is driven by the in-repo
overlay builtin/queries/latex/highlights.scm — the first such overlay,
include_str!'d as LATEX_HIGHLIGHTS (the audit-rules.scm precedent). This commit
reconciles the vendored nvim-treesitter query (previous commit) onto pmacs'
recognized capture set:
* strip @spell/@nospell — meaningless to pmacs, and clobber-risk on a
multi-capture node;
* remove the 8 #eq?/#any-of?/#lua-match? patterns — pmacs evaluates only
`#is? local`, so unevaluated they would over-match every generic command
(as conditional/emphasis) and every line comment (as a magic directive);
* remap fall-through captures: @module->keyword, @label->type,
@markup.heading*->keyword.control, @markup.link*->constant,
@markup.math->string;
* fix node-name drift: this grammar cut uses curly_group_label(_list) for the
label commands where newer latex-lsp unified them onto curly_group_text.
Tests (framing acceptance): table guard; load-and-parse including a verbatim
environment (exercises the external scanner the broken crate lacked);
highlights-resolve (doubles as the grammar/query node-name compatibility gate);
and extension resolution.

Buffer attach events until winit state exists, keep spawned daemon ownership
until the reaper handoff, and detach daemon stderr from the launcher terminal.
Tighten direct GPU CLI guidance and sibling discovery. Strengthen managed
connector unit and process acceptance coverage for transient retries, timeout
reporting, hermetic paths, and deterministic loser reaping.
Integrates canonical `main` @ 2625ec7 after PR #137 (tab-width parity)
merged. The agreed order was #137 first, this lane second: #137 was
approved and FROZEN at 5b23e11, and "frozen" is incompatible with
"rebase onto the resulting main" — landing it second would have broken
its freeze and voided its approval.
Integrated by MERGING main into the branch rather than rebasing, matching
repo precedent (Merge canonical main into vterm-tui, ... into modeline
detection). A rebase would have force-pushed away the review anchors on
the two completed review rounds of #135.
Main had also moved past this lane's base by #133/#134/#136, so the
integration surface was wider than the #135/#137 overlap: src/
semantic_render.rs was a fourth overlapping code file. It auto-merged, as
did pmacs-protocol/src/lib.rs. The single code conflict was the
pmacs_protocol import list in pmacs-gpu/src/main.rs — TAB_STOP_COLUMNS
against the terminal types — resolved as a union.
The feared semantic collision did not occur, and this is verified rather
than assumed: terminal cell geometry still uses the monospace advance and
never TAB_STOP_COLUMNS. pmacs-gpu/src/terminal.rs references neither the
constant nor display_width, and terminal_cell_viewport / terminal_run_rect
/ hit_test_cell derive from mono_advance() and code_line_height() alone.
That separation is correct by construction: a terminal's columns come
from the child, while tab expansion is a document projection concern.
Doc conflicts resolved toward landed state: the tab-width lane moves to
"Closed since the last snapshot", the #135/#137 coordination section is
kept as a resolved worked example, and the Arc 5 lines in the roadmap and
handoff now read "implemented and in review". While resolving, restored a
clause main had dropped from the handoff's injection-follow-ups list
("literals, doc-comment code);"), keeping main's strikethrough-and-SHIPPED
convention for the modeline entry.
Post-integration gates, from a clean tree: cargo fmt --check; strict
workspace clippy; pmacs-protocol 17; cargo test --lib 1,768; --features
crdt 1,944 (3 ignored each); vterm Stage 1 9/10, Stage 2 4/4, Stage 3
5/7, statusline 7/8, tab-width 2/2 (default/CRDT); M4 121 passed (3
ignored, 1 filtered); required GPU 139; workspace sweep 2,946 passed
across 84 suites (19 ignored), one invocation; git diff --check clean.
Share one fixed eight-column tab-stop contract across core and GPU renderers. Consolidate byte-to-display-column accounting, expand GPU code tabs with source provenance, align caret/hit/decoration geometry, and refresh minimap projection on edits.
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.

Add tree-sitter-json (0.24) and tree-sitter-yaml (0.7) to
BUILTIN_LANGUAGES (both ABI-current via tree-sitter-language, verified
compiling under tree-sitter 0.26), each self-contained highlights, no
injections of their own. Extensions json=.json, yaml=.yaml/.yml; root
kinds json `document`, yaml `stream`.
The payoff from the #122 injection engine is free: the markdown block
injection query already sets injection.language "yaml" for `---`
frontmatter (minus_metadata) and "toml" for `+++` (plus_metadata), so
registering yaml lights up YAML frontmatter highlighting with no extra
wiring, and ```json / ```yaml / ```yml fences resolve through the engine
(yml->yaml alias already present). Two acceptance tests pin this synergy.
LSP (builtin/runtime/lsp.lua): pmacs.lsp.config.json uses the maintained
extracted-bundle binary `vscode-json-language-server --stdio` (NOT the
stale standalone vscode-json-languageserver); MIT, no telemetry, remote
$schema fetch left enabled (no handledSchemaProtocols). pmacs.lsp.config
.yaml uses `yaml-language-server --stdio` with Red Hat telemetry
disabled by default. Both ship the exact workspace/configuration sections
each server pulls (json+http; yaml+http+redhat.telemetry) present-not-null
so the servers get defaults rather than erroring — the CMake #117 lesson.
Sections derived from server source/docs (neither binary installed on
this build machine to observe live; verify where present). Filetype
fallback entries added. JSON is the standing prerequisite for the Jupyter
.ipynb arc; handoff §6 updated.
Nine acceptance tests (grammar ABI, highlights compile, detection,
grammar<->LSP-key alignment, the two frontmatter/fence synergy proofs,
and the pinned LSP-config sections).

assemble() replaces FontSystem::new() + post-hoc load_font_data
with an explicit fontdb::Database built in today's order -- system
fonts first, the bundled JetBrains Mono second (its fontdb::ID
retained) -- then the parameterized same-family collision filter
(sanitize_font_database removes every NON-monospace face
advertising the default family; the bundled face survives by
construction), cosmic-text's generic-family defaults, and only
then FontSystem::new_with_locale_and_db (sys-locale with the
"en-US" fallback, the same resolution cosmic-text's own
constructor performs; new pmacs-gpu dependency) -- so the internal
monospace-ID set is computed over the final database, bundle
included. FontDefaults { default_family, bundled_id } lands on
State as the total-fallback anchor for the resolution work in the
next commit; query_normal_face is the shared normal-style query
(the same fontdb::Query the base Attrs imply). Debug assertions
pin both anchors present and monospaced at assembly. All 69 GPU
tests pass unchanged -- assembly preserves today's pixels.

These five languages already had LSP configs (basedpyright, gopls,
tsserver, taplo, zls) but shipped no tree-sitter grammar, so they
rendered with no lexical color. Fill the gap — 8 BUILTIN_LANGUAGES
entries across 6 crates:
- python (`tree-sitter-python`, root `module`), go (`tree-sitter-go`),
toml (`tree-sitter-toml-ng`), zig (`tree-sitter-zig`, +`.zon`) — each a
single self-contained highlights query.
- JavaScript/TypeScript family: `tree-sitter-javascript` parses both
`.js` and `.jsx`; `tree-sitter-typescript` ships two grammars
(LANGUAGE_TYPESCRIPT, LANGUAGE_TSX). The four entries — javascript,
javascriptreact, typescript, typescriptreact — mirror the LSP filetype
map so tsserver enables the JSX parser. Highlights inherit: the TS
query is a ~5-capture delta over JavaScript and JSX is a further
delta, so the entries compose base-first (js → jsx → ts), the same
pattern as `cuda` over C/C++ (typescript resolves ~22 capture classes,
typescriptreact ~24).
Each grammar's name equals its existing `pmacs.lsp.config.<name>` key,
so grammar detection (which wins over the filetype map) resolves the id
the server keys off — the file now gets BOTH highlighting and the right
server. No lsp.lua change needed. All crates ride `tree-sitter-language
0.1` with tree-sitter dev-only — no second core in the graph.
Bite-verified acceptance:
- gap_grammars_load_and_parse — each grammar's ABI accepted by the 0.26
core; a snippet parses without error at its root (covers both TS
grammars, incl. JSX).
- typescript_highlights_compose_the_javascript_base — the compiled
typescript/typescriptreact queries resolve >= 15 captures, not just the
~5-capture TS delta (the JS base is really composed in).
- builtin_languages_include_gap_grammars /
gap_grammar_extensions_resolve — entry presence + extension detection
across all 8 ids.
- m4_gap_grammars_align_with_lsp_configs — through the loaded runtime,
each path's grammar id matches an existing LSP config. Bite-verified
against pre-feature src/syntax.rs.
Ripple: two #116 shebang tests used python as their "has-LSP-but-no-
grammar" example, which this PR invalidates. Updated both — the .py +
`#!/bin/sh` precedence test now asserts a python grammar tree (not "no
tree"), and the grammarless-language-is-silent gate test switches to
`ruby` (genuinely grammarless) via a test-local shebang mapping.

Files identified by their whole basename — Dockerfile, Makefile,
CMakeLists.txt, rc dotfiles — had no detection path (extension-, then
shebang-keyed). Add a filename layer and the three grammars behind it.
- **Grammars** (BUILTIN_LANGUAGES): dockerfile via `tree-sitter-containerfile`
(the ABI-current grammar; the old `tree-sitter-dockerfile` pins
`tree-sitter ^0.20` and would fork the graph — containerfile rides
`tree-sitter-language 0.1`, tree-sitter dev-only, like the others),
make via `tree-sitter-make`, cmake via `tree-sitter-cmake`. All ship
self-contained highlights (single fragment). Extensions:
`.dockerfile`/`.containerfile`, `.mk`/`.make`, `.cmake`.
- **Filename layer**: `pmacs.parse.language_from_filename(name)` backed by
an extensible `pmacs.parse.filenames` map, wired into the precedence
chain in both syntax.lua (grammar) and lsp.lua (LSP): grammar-ext →
filetype map → filename → shebang. A recognized extension still wins;
the basename map only fires when the extension misses. Seeds the three
filenames plus shell rc dotfiles (`.bashrc`/`.zshrc`/`PKGBUILD`/… →
bash) — highlighting them against the grammar shipped in #115.
- **LSP**: `config.dockerfile` (docker-langserver --stdio) and
`config.cmake` (cmake-language-server). Make has no server, so no
`config.make` — grammar highlight only. Extension filetype fallbacks
added for id stability.
Bite-verified acceptance:
- filename_grammars_load_and_parse — each grammar's ABI is accepted by
the tree-sitter 0.26 core and parses a representative snippet without
error (dockerfile/cmake root at source_file, make at makefile).
- builtin_languages_include_dockerfile_make_cmake /
language_for_path_resolves_dockerfile_make_cmake_extensions — entry
presence and extension detection.
- m4_filename_map_resolves_special_files — the basename map (incl. path
form and dotfiles→bash), config.dockerfile/cmake commands, and no
config.make. Bite-verified against pre-feature syntax.lua.
- m4_filename_extensionless_dockerfile_highlights — an extensionless
`Dockerfile` resolves to dockerfile for LSP and gets a dockerfile parse
tree; reachable only via the filename map. Bite-verified.

Shell scripts already had LSP (bash-language-server + shellcheck/shfmt,
wired in builtin/runtime/lsp.lua), but no tree-sitter grammar, so their
text rendered without lexical color. Fill in the missing half.
- Bundle tree-sitter-bash (0.25) as a BUILTIN_LANGUAGES entry. Unlike
cuda, bash's highlights.scm is self-contained (no `; inherits:`
delta), so a single fragment suffices. The crate exports
LANGUAGE/HIGHLIGHT_QUERY over tree-sitter-language 0.1 — shared ABI
crate, no second tree-sitter in the graph.
- Extension set is wider than the `.sh`/`.bash` the LSP filetype map
covered: `.zsh`/`.ksh`/`.ash` are close-enough dialects and `.bats`
is bash. The grammar's language name is `bash`, matching the
`pmacs.lsp.config.bash` key, so opening any of these also auto-attaches
bash-language-server (shellcheck declines zsh, so `.zsh` diagnostics
may be sparse; highlighting is unaffected). lsp.lua's filetype map is
extended to the same set as the belt-and-suspenders fallback.
- Extensionless shebang scripts (`#!/bin/sh`) and rc dotfiles
(`.bashrc`) are intentionally NOT covered: detection is extension-keyed
and shebang/filename sniffing is a separate, deferred feature.
Bite-verified acceptance:
- bash_grammar_loads_and_parses_script — the 0.25 grammar's ABI is
accepted by the 0.26 core (set_language succeeds at runtime) and a
representative script (shebang, set, parameter expansion, function,
if) parses without error, rooting at `program`.
- builtin_languages_include_bash / language_for_path_resolves_bash_
extensions — entry presence and detection across the wider set.
- bash_highlights_compile_with_captures — the self-contained query
compiles against the grammar with real capture classes.
- m4_12_default_bundle_wires_bash — through the loaded runtime,
config.bash targets bash-language-server and both grammar detection
and the filetype fallback resolve the new extensions to `bash`.

Opening a .cu/.cuh file previously resolved to no language, so no
server attached and there was no highlighting. Wire CUDA end to end,
mirroring the existing C/C++ path:
- Bundle tree-sitter-cuda (0.21) as a new BUILTIN_LANGUAGES entry
claiming .cu/.cuh, with its own HIGHLIGHTS_QUERY. A dedicated grammar
rather than reusing cpp: the C++ grammar errors on the
<<<grid, block>>> kernel-launch syntax. The crate rides
tree-sitter-language 0.1 (its tree-sitter dep is dev-only), so it
shares the ABI crate with the other grammars — no second tree-sitter
in the graph.
- pmacs.lsp.config.cuda targets clangd (the same binary that serves
C/C++; language_id "cuda" so clangd enters its CUDA parse mode), and
.cu/.cuh filetype fallbacks map to "cuda" to keep the LSP id stable
if the grammar is ever dropped. LspStyleView layers clangd's CUDA
semantic tokens on top, exactly as for C/C++.
Bite-verified acceptance:
- cuda_grammar_loads_and_parses_kernel_launch — proves the 0.21
grammar's ABI is accepted by the 0.26 core (set_language succeeds at
runtime, which the compile step cannot confirm) and that the entry
wired the CUDA grammar, not a cpp fallback: the <<<...>>> launch
parses without error, whereas the cpp grammar reports an error on the
same source (verified out of band).
- builtin_languages_include_cuda / language_for_path_resolves_cuda_
extensions — entry presence and .cu/.cuh detection.
- m4_12_default_bundle_wires_cuda — config.cuda targets clangd and the
filetype + grammar detection resolve to "cuda" through the loaded
runtime.

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.

The regex sibling of find_all, on regex::bytes::Regex over the whole
buffer. Returns Option<Vec<ByteRange>>: Some for a valid pattern
(possibly empty), None when it fails to compile — so the caller can
tell an invalid pattern (show [invalid]) from a valid zero-match
search.
Smart-case mirrors the literal path: case-insensitive via a (?i)
prefix unless the pattern carries an uppercase letter. Multi-line is
free — the regex runs over the whole byte slice, so an explicit \n (or
(?s).) spans lines while `.` keeps its default. Zero-width matches
(a*, ^, $) are filtered. The regex crate (already transitive in the
lockfile) is promoted to a direct dependency; its linear-time engine
makes a pathological pattern slow at worst, never catastrophic.
Tests: pattern match, smart-case both ways, \n-spanning + dotall +
default-no-cross, invalid→None vs valid-zero→Some(empty), zero-width
filter.

pmacs-gpu now has two run modes:
- no args: hello-world (session-2 behavior preserved)
- --attach <socket>: connect to a pmacs daemon, negotiate
semantic_render + crdt_replica, import BufferSnapshot into a local
loro replica, render the rope text. Live CrdtOp updates apply as
they arrive.
Architecture:
- pmacs-gpu/src/attach.rs (new): UnixStream connect + Hello /
AttachRequest handshake on the main thread; spawns a reader thread
that pumps decoded InstanceMessage frames through the winit
EventLoopProxy as AppEvent::Attach(AttachEvent::Message). Clean EOF
or transport errors surface as AttachEvent::Disconnected. Reader
thread holds the read half of the stream; AttachClient retains the
write half (unused yet — session 4 wires FrontendEvents back).
- pmacs-gpu/src/main.rs: ApplicationHandler<AppEvent> with a
user_event handler that dispatches Message variants. BufferSnapshot
builds a fresh LoroDoc, imports the snapshot bytes, extracts text
via doc.get_text('body').to_string(), and re-shapes the glyphon
buffer. CrdtOp passes the op bytes through doc.import (loro
accepts both shapes), re-extracts text, re-shapes. Other
InstanceMessage variants are intentionally ignored at session 3.
- Font size dropped from 48pt to 16pt now that we may render full
files (the hello-world 48pt was fine for one line, awful for code).
- Initial text is '(connecting...)' in attach mode, 'hello, pmacs' in
hello-world; attach failure falls back to '(attach failed; see
stderr)' so the window still opens.
One small finding logged in attach.rs's connect() doc: AttachRequest's
initial_size field is a CellSize (rows × cols), nominally
TUI-shaped. Sent as a placeholder (24×80) — a structural answer
('what does initial size mean for a pixel frontend?') belongs in its
own protocol thread, not session 3. Classified under rule (iii) as
deferred.
Container id for the loro text container ('body') hardcoded to match
pmacs::crdt::CrdtState — second finding worth pre-recording: the
container name is a wire-adjacent convention that isn't carried on
the wire itself. Both ends have to agree out-of-band. Not blocking
for session 3 but a structural smell for the producer arc. Logged
as deferred (rule iii structural; the answer is probably 'thread the
container id through BufferSnapshot' but it's not session-3 scope).
Gates: cargo fmt, cargo clippy --all-targets -D warnings (whole
workspace) clean; lib 1303 + pmacs-protocol 11 = 1314 unchanged;
m4_acceptance 83; m11_5_semantic_acceptance --features crdt 2.
Manual validation pending — agent environment is headless. User
walks through: start a pmacs daemon, run pmacs-gpu --attach <socket>,
confirm the window renders the daemon's file contents.

Adds the pmacs-gpu binary crate to the workspace. wgpu 29.0 + winit
0.30 + glyphon 0.11 (cosmic-text 0.18 via re-export) + pollster +
env_logger; pmacs-protocol in the dep graph but not consumed yet
(session 3 wires the attach loop).
The binary opens an 800x200 window titled 'pmacs-gpu hello-world',
sets up wgpu against its surface, configures glyphon with the bundled
JetBrains Mono Regular, and renders 'hello, pmacs' once per redraw.
Close button or Escape exits. Resize re-configures the surface and
glyphon viewport. Surface acquisition matches wgpu 29's
CurrentSurfaceTexture enum (success/suboptimal render through; lost/
outdated re-configure; timeout/occluded skip the frame).
Bundled assets: pmacs-gpu/fonts/JetBrainsMono-Regular.ttf (268 KB)
and pmacs-gpu/fonts/OFL.txt. Font shipped as required by the SIL
Open Font License 1.1.
One finding surfaced during the move and absorbed under rule (iii)
of the framing pass (small / no structural change): the design doc
recorded JetBrains Mono as Apache 2.0; the actual license has been
OFL since the family's open-source release. Doc corrected in
docs/pmacs-gpu-design.md.
Gates: cargo fmt + cargo clippy --all-targets -D warnings clean for
the whole workspace; cargo test --lib still 1314 (pmacs main crate
untouched); m4_acceptance 83; m11_5_semantic_acceptance --features
crdt 2.
Visual confirmation pending — agent environment is headless, so
'window opens, text renders' is user-side validation.

Workspace skeleton: root Cargo.toml becomes a workspace with members
[".", "pmacs-protocol"]; [workspace.dependencies] pins serde,
postcard, thiserror so both crates use byte-identical versions (the
wire format depends on it). pmacs main package keeps its existing
shape (no file moves); it just gains pmacs-protocol as a path
dependency.
Identity types moved: BufferId (from buffer.rs), FrontendId + ByteRange
(from protocol.rs), Position type alias (from rope.rs). All four are
self-contained — no custom-type dependencies — so the first stage of
the move can land atomically without dragging cell/message types along.
src/buffer.rs / src/protocol.rs / src/rope.rs each gain a 'pub use
pmacs_protocol::...' re-export for the moved names, so existing
internal imports (crate::buffer::BufferId, crate::rope::Position, etc.)
continue to resolve unchanged. New consumers (pmacs-gpu, debug tools)
will depend on pmacs-protocol directly.
One visibility change: BufferId::from_raw was pub(crate); promoted to
pub with a doc note that it's not stable API for external consumers.
The (crate) restriction was advisory only — external deserialization
already worked via the derived Deserialize, so making it pub doesn't
widen the actual surface, just makes it honest.
Lib gate: 1314 passed, no regressions.

Drops the policy-A exclusivity that left grammar-backed languages
without LSP semantic refinement. Adds tree-sitter-c (.c/.h) and
tree-sitter-cpp (.cpp/.cc/.cxx/.hpp/...) to the bundle so the grid
TUI gets lexical highlighting (keywords / strings / operators) on
first open. The Lua attach in builtin/runtime/lsp.lua now pushes
LspStyleView whenever an LSP server is up, regardless of grammar
presence; with both views attached the cell-painter pipeline runs
SyntaxHighlightView first (lexical) then LspStyleView (semantic)
and their styles compose through crate::overlay::merge_styles. The
result is the VSCode / Zed "TextMate + LSP semantic tokens" model
on a terminal grid: keywords colored by tree-sitter, identifiers
refined by clangd's semantic tokens.
`.h` is ambiguous C / C++; the `c` BUILTIN_LANGUAGES entry claims it
to match the LSP filetype map's default. Users who want `.h` parsed
as C++ can override via Lua (extension → language map).
Note the tree-sitter-c / -cpp crates expose `HIGHLIGHT_QUERY`
(singular), matching tree-sitter-md's `HIGHLIGHT_QUERY_BLOCK`
convention; tree-sitter-rust / -lua use `HIGHLIGHTS_QUERY` (plural).
Same bundled highlights.scm either way.
Regression guard: builtin_languages_include_c_and_cpp asserts the
language entries exist and claim their canonical extensions. The
LspStyleView module doc rewritten to reflect dual-authority
composition; the existing headline test's comment updated (the
test fixture still attaches only LspStyleView directly, so its
asserted cells reflect the LSP authority alone — Lua-level
attach_buffer is what exercises composition end-to-end).

Roadmap steps #3–#6 (post-CI-green doc/version work; no source
change — the CI-validated tree at ed78465 is unchanged).
- CHANGELOG: authored the [1.0.0] --- 2026-05-18 body. M7–M10 arc
(third-party packages / fs API + dired-magit-outline / MCP /
multi-frontend CRDT collaboration) over the 0.1.0 M1–M6 preview;
the pulled-forward v0.2-prerequisite public APIs; SSH stderr
Changed + Broken-pipe Fixed carried from Unreleased; Known
limitations (per-frontend undo not persisted across reattach,
Finding 4; macOS m6_5 REPL ctrl-c/exit-marker timing); project
posture (forbid(unsafe_code), 1.95.0 pin, cross-flavor CI).
- Version: 0.1.0 -> 1.0.0 (Cargo.toml + Cargo.lock). Production
version reporting already flows from CARGO_PKG_VERSION; verified
`pmacs --version` -> `pmacs 1.0.0`, version-sensitive tests pass.
- README: Status -> v1.0.0 stable, contributions open; build line
-> the rust-toolchain.toml-pinned 1.95.0.
- MSRV: rust-version 1.85 -> 1.95 to match the validated toolchain
pin (was an unverified floor; pmacs is a pinned-toolchain app, so
MSRV reflects the pinned/validated compiler).
Quiescent audit (#6): doc/version-only delta from CI-green ed78465;
build/version-tests/fmt verified clean on pinned 1.95.0; prose
reviewed accurate. SP-9 (macOS m6_5) logged in the gitignored
V0.2-PREREQUISITES.md.
Not in scope here / remaining: the recorded two-laptop manual
acceptance run (#7, operator) and the v1.0.0 tag (#8, operator).

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.

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
