Post-merge housekeeping owed from #142, kept as its own docs PR (no
runtime code).
- agent-handoff.md §1: bump main to c49a8c7, add the folding Stage 1
substrate bullet (store/View, structural source, C-c @ surface,
command-path unfold, FoldState production; no protocol bump), refresh
the "Last updated" line and the roadmap Arc 6 entry, and note Stage 2
is in framing on folding-tui (the visible-line-map reframe).
- active-work.md: retire the Stage 1 folding lane (PR #142 was OPEN),
add a "Closed since the last snapshot" entry for #142, open the
Stage 2 (grid/daemon collapse) framing lane on folding-tui, and
refresh the canonical base snapshot to c49a8c7.

PR #149 review round 5, finding 1 — correct, and both round-4 bugs did
survive through the intercept path.
Round 4 moved the widening off the point and onto `edit_start_of(&op)`,
but ran it in `run_buffer_edit` BEFORE `run_managed_edit`. A managed
buffer intercept may legally rewrite `pos` / `start` / `end`
(`LuaInterceptView::intercept_edit`), so the requested op is not where
the edit lands:
- requested outside -> intercept relocates inside: the edit stayed
hidden;
- requested inside -> intercept relocates outside: an unrelated fold
opened.
The seam still covers BOTH paths — hooking only `run_managed_edit` would
let an interactive `bypass_intercept` edit escape, which is why the
framing put it on the common entry — but each path now keys on its own
effective site:
- `run_bypass_edit` applies its op verbatim, so `run_buffer_edit`
hooks it there;
- `run_managed_edit` hooks after the intercept chain settles and
before the apply, on the op the chain returned. A chain that raises
applies nothing, so it unfolds nothing.
The registry borrow is released at that point, and the helper reads only
`SharedCore` + the fold registry, so no borrow conflicts with phase 3.
Three new tests, all through real `M-x` with a real
`pmacs.buffer.add_intercept`: relocate-into-a-fold must unfold,
relocate-out-of-a-fold must not, and a rejected chain must not. Each
asserts the buffer text first, so the test fails loudly if the intercept
stops relocating rather than silently passing.
Suite 45 -> 48.

Keep foreign BufferSnapshot publications out of existing semantic GPU
sessions while retaining grid-replica coherence. Treat dead peer writes as
peer-local failures, restore active-frontend cleanup, deterministic probe
readiness, GPU logging, shared tilde expansion, and accurate docs.
Add focused publication and cleanup coverage and record the two-window
Wayland/Vulkan smoke plus the complete post-review gate results.
All four findings were correct.
F1 (major) — the Lua widening keyed on the POINT, not the edit site.
Q#FD19 condition (iii) is `edit.range.start`; `run_buffer_edit` discarded
`op` and opened whatever fold contained `window.cursor`. Two wrong
behaviors followed: a command inserting elsewhere opened an unrelated
fold at the point, and — worse — a command editing INTO a fold from an
outside point left its edit hidden. `run_buffer_edit` now reads
`edit_start_of(&op)` before `op` is consumed and passes it down. The
`apply_active_edit` funnel stays point-keyed, which is correct and
deliberate: the six primitives, yank, and query-replace all place point
at the edit site first, and only the Lua path can diverge — now said so
in the doc comment.
The acceptance test encoded the wrong behavior (inserted at byte 0,
expected the cursor's fold to open). Replaced by two tests that pin both
directions, plus the framing's named **comment-toggle** case driven
through the real `M-;` on a file-backed Rust buffer rather than a
synthetic mutator.
F2 (major) — hidden-cursor motion normalized only the row. `move_up` /
`move_down` clamped `coord.row` but derived `goal` from the hidden
line's raw column, and returned early at a buffer boundary without
normalizing at all, so `Up` inside a fold headed on line 0 left the
logical cursor hidden. Added `normalize_cursor_to_visible`, which
projects the whole POSITION through `visible_position` as a real
mutation before any step is computed (and drops the sticky goal column,
since the jump is discontinuous). Paging shares it — the same latent
bug. The old test used equal-width lines and asserted only the line, so
it could not tell the two apart; the new fixture is deliberately ragged
and asserts the resulting BYTE in both directions, plus the boundary
case.
F3 (moderate) — `set_view_top` bypassed the fold clamp. Q#FD12/Q#FD18
say `view_top` is always set through `clamp_view_top`, naming the
`set_view_top` contract specifically. Rendering repaired it at the next
frame, but until then `view_top()` handed out a hidden line and
command/event reckoning could start from a non-visible origin. The
clamp now lives in the setter — the contract's home, what `saveplace`
and `pmacs.editor.set_view_top` call. New test reads `view_top()`
directly after the setter, before any paint.
F4 (moderate) — the suite claimed items 1–14 but omitted approved
clauses. Added: peer SELECTION endpoint projection with hidden interiors
dropped; the crossing-fold repeat for the peer cursor AND a peer
selection endpoint; a style/syntax span straddling a fold (alignment on
the shifted row); the completion popup anchored below a fold; and peer
presence in the split-buffer case using the RECIPIENT window's map.
Suite: 35 -> 45 tests. Eight new bite cases, each falsifying exactly the
line that implements its claim.

`main` moved from c49a8c7 (folding Stage 1, #142) to 47581f4 (web
grammars, #146) while Stage 2 was in framing and implementation. The
text merge is clean, but it is NOT semantically clean: #146 added three
new `Viewport { .. }` literals to `src/highlight.rs`'s unit tests, and
Stage 2 gives `Viewport` a `folds` field. Merged alone, `cargo test
--lib` fails to compile — so the carry-over is resolved here rather
than left for CI to discover.
Merged (not rebased) so the four framing revisions the review rounds
cite by SHA (59410c0, e221f13, 8160d66, 4222ffa) stay reachable.
Full gate suite re-run on the merged tree.

`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.

Bite-verification found the Q#FD19 active-window-buffer requirement's
test vacuous: `other` held no fold, so removing the guard changed
nothing — `unfold_containing` on a store-less buffer is a no-op either
way. The guard's real job is to stop the invoking frontend's POINT from
naming a place in a buffer it is not looking at, so the fixture now
gives `other` a fold whose range contains the active window's cursor
byte. Reverting the guard now opens it (0 != 1).
Verified: with `if window.buffer_id != id { return; }` replaced by a
no-op, the test fails on a clean assertion.

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.

Update the framing, durable handoff, and active-work ledger after integrating
current canonical main and completing the required gates and real GPU smoke.
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.
Route command-time visible-line maps through each operation's target
window, while retaining the acting frontend as the projection-policy
owner. Model nested and crossing folds as merged hidden components so
row and byte clamps always resolve to one actually visible head.
Also key projection on the negotiated render selection and correct the
unmerged status of the separate Stage 1 housekeeping PR.
Round 2's three findings + two nits, all verified against c49a8c7:
- F1 (major): fold-aware motion must be frontend-projection scoped. Shared
EditorCore::move_up/down/page_* would make a simultaneous unfolded GPU
session skip source lines it still displays (a grid + a semantic session
can attach to one buffer, daemon.rs:876). Add a per-FrontendView
`fold_projection_active` flag (editor_core.rs:240, set at attach / cleared
at detach); gate ALL command-time visible-line reckoning (motion, paging,
wheel, click, auto-scroll) on it. Render-time clamps are already
grid-path-only. New Q#FD21 + simultaneous TUI+semantic acceptance.
- F2 (major): render maps must be per WINDOW, not per frame — paint_frame
and the presence pass iterate windows with distinct buffer_ids
(editor.rs:2922, overlay_paint.rs:124). Specify one map per rendered
nonterminal window (keyed on window buffer_id + TextView); peer presence
uses the recipient window's map. New split-of-different-buffers acceptance.
- F3 (moderate): hidden positions need COLUMN projection, not only row
clamping. Add `visible_position_of(pos)` -> outermost fold's range.start
(end of visible head line, Stage 1's point-move target) for local/peer
carets and selection endpoints; hidden interiors still drop. New
hidden-cursor-column-differs acceptance.
- Nits: fix the Viewport<'a> typo; state build cost honestly as O(folds)
with a byte->line lookup per fold (B4).
PR #147 (the #142 housekeeping) confirmed clean by the reviewer, no findings.

Review found that adding ("attribute", fg(3)) for HTML/CSS also colours the
@attribute capture three already-bundled grammars emit — rust (attribute_item),
lua (<const>), yaml (directives) — which were previously unpainted. Verified on
a Rust buffer: #[derive(Debug)] now paints uniformly yellow (fg 3), an
improvement over unpainted and the distinct-attribute convention most editors
follow.
Name this retro-paint as intended in the framing (Q#WEB4, rev 4) and pin it with
rust_attribute_repaints_via_shared_attribute_capture so it is a chosen effect,
not incidental. @tag is unaffected (HTML/CSS only).

Round 1's five findings + two rulings, all verified against c49a8c7:
- F1 (major): nested folds. `head_of`(innermost) could clamp onto a
still-hidden inner head. Replace with `visible_head_of` (outermost
visible head); `view_top` clamps BACKWARD to the head, not forward
past the fold; relative numbers anchor on the clamped visible cursor.
- F2 (major): the consumer census was incomplete. Add the full §2.2
table — local selection (editor.rs:3241), peer presence
(overlay_paint.rs:159, after paint_frame), mode-line indicator
(editor.rs:3803), style/search/completion overlays — and make TUI
peer-presence fold behavior explicit scope.
- F3 (major): line numbers default Off => gutter_w==0 => no sign cell.
Make the fold glyph conditional: off => ellipsis only; on => sign
cell with diagnostic priority. Dedicated column (unconditional) named
as a deferred layout change.
- F4 (major): a frame-pinned map can't serve command-time motion, and
Viewport is Copy. Reframe as one derivation primitive with per-phase
short-lived instances (render via Option<&VisibleLineMap> on a
lifetime-bearing Viewport, preserving Copy; after-frame direct;
command-time fresh); home usable from EditorCore.
- F5 (moderate): key the Lua-path widening on InteractiveCommandOrigin
(editor.rs:53), hook the common run_buffer_edit (not only
run_managed_edit) so bypass_intercept edits don't escape, require the
target to be the invoking frontend's active-window buffer, and
explicitly DEFER undo/redo unfold.
Rulings: Q#FD17 include (normalize a hidden cursor to the visible head
before stepping); #142 housekeeping stays a separate docs PR.
Acceptance expanded to pin nested-fold/shared-cursor, local selection,
peer presence, an ordinary overlay across a fold, completion anchoring,
the scroll indicator, and both gutter-off/gutter-on fold-marker cases.

Reframe Arc 6 folding Stage 2 in detail off canonical main @ c49a8c7
(Stage 1 / #142 merged), per the parent framing's §8/§14. Continues the
Q#FD scheme from Q#FD12.
Stage 2 makes the daemon grid renderer fold-aware: collapse hidden lines,
head-line ellipsis + gutter fold glyph, fold-aware line numbers
(visible-line relative distance), diagnostic-sign clamp-to-head, caret
clamp, visible-line viewport/scroll accounting, and the interactive-Lua
unfold widening (yank/query-replace/comment). No wire schema or protocol
change — FoldState production (Stage 1) is untouched; the GPU path is
Stage 3.
Scout findings that shaped the framing:
- The TUI has NO non-identity source-line->display-row map today; the
identity `view_top + row` is baked into ~7 sites. Folding is the first
such map, so Stage 2's spine is one shared per-frame visible-line map
(Q#FD12) that the render loop and every view_top-arithmetic site
consult; collapse lives in TextView::render, not the diff shell.
- Correcting the parent's premise: yank + query-replace are
apply_active_edit callers (local), not Lua-mutator callers; only
comment-toggle/yank-pop take the Lua path (shared with the
remote/optimistic-CRDT apply that stays deferred to Stage 3). The
widening hooks the local funnels only (Q#FD19).
One open scope fork flagged for the user: Q#FD17 (fold-aware vertical
line-motion vs render-time caret clamp only).

non-structural framing findings. Keep implementation gated on explicit user
approval.
Pin launcher-owned tilde expansion, require same-buffer dedup hooks, fail
closed when hooks kill the target, and document stderr feedback during the
pre-window bootstrap wait. Record the observed protocol-version echo and
non-Unicode argv panic.
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.

portable Revision 1 framing checkpoint, scope, recovery command, and approval
boundary.
Round 2 correctly found the Finding-2/3 fixes were unpinned (reverting
them left the suite green). Both are now bite-verified:
- **Kill-path purge (Finding 2).** Replaced the direct
`forget_buffer(id)` unit test with
`killing_a_buffer_through_the_real_path_purges_its_fold_store`, which
drives `pmacs.buffer.remove` — the production route through
`after_buffer_removed` — and asserts the store is gone via the dead id
(BufferIds never recycle). Mirrors config_registry's real-kill-path
test. Bite-verified: reverting the `after_buffer_removed` fold branch
turns it red.
- **close-all point move (Finding 3).** Added
`close_all_command_moves_point_to_enclosing_head`, which invokes the
`fold.close-all` command with the point inside the second of two
top-level fns and asserts the cursor landed on that fn's head-line
content end (and both folds exist). Bite-verified: reverting close_all's
`maybe_move_point` loop turns it red.
- Ledger: `docs/active-work.md` folding lane now records PR #142 OPEN +
the two landed review rounds (was "opens once the gate suite is green").
Correction to the round-1 gate report: the acceptance suite is **21**
tests (round 1 was 20, not 24 — a tally slip), green under default and
`--features crdt`. Full gate suite otherwise green (fmt, clippy
--workspace --all-targets, git diff --check).

- **Finding 1 (bug):** a delete starting exactly at a fold's `end`
removed the `\n` that `end` names — the last hidden line's terminator —
but the strictly-after arm (`os >= e`) kept the fold, leaving a mid-line
end. `translate`'s after-arm is now `os > e || (os == e && old_len == 0)`
so a pure insert at `e` still stays outside while a delete at `e` falls
to the drop arm, symmetric with the head side. New unit test
`delete_starting_at_tail_boundary_drops_fold` (bite-verified).
- **Finding 2:** `pmacs.buffer.kill` didn't clean the fold registry.
Added `FoldRegistry::forget_buffer(id)` (id-keyed; the view died with the
buffer) and wired it into `after_buffer_removed`, mirroring the
keymap/config cleanup; the registry is now stashed as Lua app-data.
`forget(&mut Buffer)` is clarified as the revert/reload reset.
- **Finding 3:** `fold.close-all` now moves the invoking point to the head
when it closes a fold around it (Q#FD3); the data-API `fold` exemption
(programmatic, no invoking point) is named in the module doc.
- Nits: dropped the dead `!(both empty)` conjunct in `fold_state_msg`;
replaced the trivial fresh-registry assert; added coverage for the
stale-tree refuse via a fold command, the read-only-buffer rejection
(Q#FD11), and unfold normalizing an arbitrary range.

The shipped latex_highlights_resolve covered only the compile / capture-name
gate; the approved framing's acceptance 3 also requires parsing a document and
asserting painted output (the grid_paints_injected_child_keyword template).
tree-sitter compiles a pattern that uses a valid field on the wrong node and
then silently never matches, which the compile gate cannot catch — a real risk
given this grammar cut's structural drift from what the nvim query targets.
latex_grid_paints_section_and_command parses `\section{Intro}` + `\foo{bar}` and
asserts the \foo command_name paints @function (non-default) and the section
title text paints @keyword.control (bold), proving the reconciled query actually
matches, not merely compiles.

Advance the framing to Revision 6 and record the strengthened non-CRDT,
Ctrl-C, strict-operand, probe-throttling, and PID-cleanup contracts. Update the
durable and volatile checkpoints to implementation commit 154cb9f.
Throttle the managed probe after its event channel closes, reject option-like
path operands, and document the connector test seam. Strengthen non-CRDT and
Ctrl-C acceptance so socket side effects and a pre-signal surviving frontend
are exercised, while avoiding cleanup signals to already-reaped daemon PIDs.
The fold engine behind `docs/folding-framing.md` (approved rev 5): a
per-buffer fold store, a structural tree-sitter fold source, the
state-aware Lua command + data-API surface with the Emacs hideshow
`C-c @` bindings, the dispatch-layer pre-edit unfold, and `FoldState`
production. No rendering — Stages 2 (grid) and 3 (GPU) consume the store.
- `src/fold.rs`: `FoldStore` (a buffer-attached `View` that translates
ranges on every edit and drops any whose head/tail the edit crosses,
provenance-blind — Q#FD6), the structural source (nearest block-like
node >= 2 source lines -> introducer<->body -> **derived head line**,
the line immediately above the first hidden line, so wrapped signatures
and `where` clauses stay visible per R3-1 -> **closer-aware tail**, a
closing-delimiter line stays visible per R2-5), injection-layer walk,
`(start, end]` containment, and the state-aware ops (close innermost
open / open outermost closed / org-TAB cycle). Stale/absent tree
refuses (Q#FD10).
- `src/lua_bindings/fold.rs`: `pmacs.fold.*` — explicit-buffer data API
(`fold`/`unfold`/`folds`/`toggle`) + interactive helpers, validation
(Q#FD11: document buffer, UTF-8 boundaries, >= 1 hidden line — Q#FD9
falls out of the last clause), point-moves-to-head (Q#FD3).
- `builtin/runtime/fold.lua`: `fold.toggle/close/open/close-all/open-all`
commands + the `C-c @` prefix set (Q#FD4).
- `src/editor_core.rs`: the six point-anchored edit primitives run the
pre-edit unfold keyed on the authenticated source's point (Q#FD5,
command path); `EditorCore` owns the shared `FoldRegistry`.
- `src/semantic_render.rs`: the `FoldState` producer —
authoritative-empty, diff-suppressed, baseline resets on
`BufferSnapshot` (Q#FD8); the "never emitted" pin split so
`BlockAdornments` stays unproduced.
- `tests/folding_acceptance.rs` (16) over real Rust/Python/markdown
grammars + `fold_state_producer_transitions` + 15 engine unit tests.

Advance the active and durable checkpoints to 69825d0 and clarify that every
spawned managed daemon enters the named reaper before connection or handshake
work can fail.
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.

Transfer every successfully spawned daemon child to the named reaper before
any connection or handshake step can fail. Read early exit status from shared
reaper facts, eliminating fallible child-handle paths that could return without
reaping.
Advance the framing to Revision 5 and record the reviewed lifecycle, CLI, and
acceptance contracts. Update the durable and volatile handoffs with checkpoint
82355ca and the completed verification matrix.
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.

Committed byte-for-byte before any reconciliation so the follow-up commit's
diff shows exactly which captures/predicates were curated onto pmacs' recognized
set. This is the first in-repo grammar-query overlay (per framing Q#LX2); the
audit-rules.scm include_str! path is the precedent.

Carve the frontend-agnostic, conflict-free substrate out of the parent
inline-math arc: Stage 1 bundles a LaTeX/TeX grammar for .tex/.latex/.sty/.cls
highlighting; the math parser (Tier 2) and GPU render (Tier 4) are deferred to
the inline-math arc. Framing approved through three review rounds; provenance
diff of the chosen grammar crate against upstream latex-lsp is discharged
(grammar.js/scanner.c byte-identical).

Update the durable handoff and volatile active-work ledger for open PR #141, including the implementation checkpoint, accepted architecture, verification record, visible Wayland/Vulkan smoke, and cross-machine recovery commands.
Add the root --gpu broker, strict GPU entry points, daemon connect-or-start orchestration, process-group isolation, bounded retry, named child reaping, and a deterministic headless lifecycle probe. Cover the complete launch matrix with real subprocess acceptance, make root Cargo runs unambiguous, and document the coherent build and one-command workflow.
