Advance the active lane to Revision 2 and record closure of all four
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.
Add tree-sitter HTML and CSS grammars for .html/.htm/.xhtml and .css
highlighting, and light up HTML's <script>->javascript / <style>->css
injections (the north-star injection consumer). Both crates export their query
constants over the tree-sitter-language shim (no overlay, ABI-fine). The only
reconciliation is two new capture entries (tag, attribute) in highlight.rs.
Framing approved through three review rounds.

Advance the volatile ledger to the current canonical base and record the
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).

The parent-arc framing was authored on the desktop but never tracked, so
references to it — from the merged latex-grammar lane framing and its Cargo.toml
comment (#144) — dangled on a fresh clone. Commit it as its own docs change and
drop the now-stale "untracked, desktop-only" caveat from the lane framing.
Frames the full four-tier inline-math renderer (detection -> parse -> layout ->
GPU render). Stage 1 (LaTeX grammar) shipped as #144; the math parser (Tier 2),
layout (Tier 3), GPU render (Tier 4), and (math_environment) @math injection are
deferred, tracked in docs/latex-grammar-math-substrate-framing.md.

Advance the durable snapshot to merge 63fbc66, record the green CI rerun, and
remove the completed GPU invocation lane from the volatile active-work ledger.
The Cargo.toml comment and the lane framing both cited docs/inline-math-framing.md,
which is an untracked, desktop-only doc — the path dangles on a fresh clone.
Point the Cargo.toml comment at the committed lane framing instead, and note the
parent's untracked status in the framing header (committing it as its own docs
PR, or listing it in the handoff's machine-local inventory, remains a tracked
follow-up).

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.
Advance the active and durable checkpoints to 69825d0 and clarify that every

work can fail.
Advance the framing to Revision 5 and record the reviewed lifecycle, CLI, and

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.
Q#FD4 settled: the user chose Emacs hideshow parity, so Stage 1 ships the
`C-c @` prefix set (`C-c <letter>` is fully taken by the LSP surface; the
hs-minor-mode prefix collides with nothing). §6/§9 now list the five
bindings; §0 records the rev 4 -> rev 5 approval note; §14 records the
rebase onto canonical `main` @ 96d0bae at implementation start. Bet B1
accepted as framed. active-work.md folding lane flipped to APPROVED /
Stage 1 implementing.

One major, three minors, and a nit from the third review, all fixed:
R3-1 (major, derived head line): rev 3's head-selection ascend was not a
no-op for brace languages — rustfmt wraps long signatures
(fn foo( / a: u32, / ) -> bool {) and puts { on its own line under where
clauses, so block.start_line > parent.start_line, the ascend fired, and
the fold hid the wrapped signature: the R2-5 defect class one level up.
Replaced by a derived head line — the interior comes from the body node
alone (closer-aware tail unchanged) and the head is the line immediately
above the first hidden line (B.start_line - 1 for an introduced
delimiter-less body, B.start_line otherwise). Emacs hideshow / LSP
foldingRange parity: the fold hides the body, nothing else. The
introducer<->body association survives for matching and close-all only.
Acceptance 1 gains wrapped-signature cases in both grammar shapes.
R3-2: "innermost-first" on a shared head line made the outer fold
unreachable via fold.toggle (close inner, reopen inner, forever) and
allowed zero-visible-change presses. Replaced by state-aware ordering:
close acts on the innermost open fold, open on the outermost closed
fold, toggle cycles org-TAB-style (close inward-out, then open all).
Acceptance 9 updated.
R3-3: Stage 1's "command path" is dispatch_key self-insert/delete only;
interactive Lua commands (yank, query-replace, comment-toggle) mutate
through the Lua mutator path and classify programmatic, so their edits
land inside a fold without unfolding. Stated as the intended Stage 1
line; widening the classifier to interactive Lua command contexts is a
named Stage 2 obligation beside Stage 3's CRDT-origin unfold.
R3-4: the data API's normalization of an arbitrary range is now defined
(head = line containing start; hidden = full lines strictly after it
through the line containing end, exclusive of an end at a line start).
Nit: stored-range containment pinned start-exclusive/end-inclusive with
the matching View boundary bias, so typing at the end of a head line
neither unfolds nor lands hidden; acceptance 6 asserts it.
Also: Sec 14 records that canonical main has advanced past the cac4961
base (docs + tab-width #137, no Stage 1 overlap; rebase at
implementation start), and the active-work folding lane is brought
current (head was stale at rev 1).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Five majors + four minors from the second review, all fixed:
R2-1 (head line on indentation grammars): tree-sitter-python's block
starts on the first statement line, so the old heuristic made a body line
the fold head and left def foo(): headless. Added a head-selection ascend
rule (block-like node -> ascend to the introducer parent while
parent.start_line < block.start_line), a no-op for brace languages.
Acceptance 1 now tests both Rust and Python.
R2-2 (Q#FD5 cannot live in the View): View::on_edit(&Buffer,&Edit) and
Edit carry no source frontend and no point-inside signal (only crdt_op),
verified at overlay.rs:248 / rope.rs. The store View now does translate +
drop only; the interactive unfold is a pre-edit step at the dispatch layer
that holds the authenticated frontend and its point.
R2-3 (CRDT typing misclassified): the classifier is the authenticated
source frontend's point, not the transport — a GPU user's CRDT-op insert
inside a fold is interactive. Stage 1 implements the command path;
CRDT-origin unfold is a named Stage 3 obligation.
R2-4 (#120 stale-mirror trap): revert drops the store + emits
BufferSnapshot + resets the baseline, so the empty store is suppressed as
'initial empty' and the GPU keeps stale folds unless its snapshot arm
clears the fold mirror. Pinned as a Stage 3 obligation and in acceptance 7.
R2-5 (line-aligned tail hid non-member text): } else { / }, [deps]) —
now the closing-delimiter line stays visible (closer-aware tail);
delimiter-less nodes still hide through the last body line. Decided, not
bet.
Minors: unfold is plural (nested); shared head lines toggle
innermost-first; Q#FD9's reason corrected to the >=1-hidden-line rule (not
bounds); and the Stage 2/3 sketch now names fold-aware LineNumbers,
visible-line viewport/scroll accounting, and hidden-line sign/presence
clamp-or-drop.
Seven findings from the first review, all fixed:
F1 (architectural): the grid TUI is daemon-rendered and never receives
FoldState (advertises semantic_render:false), so its fold collapse is
instance-side work in the daemon grid renderer reading the store directly
— the vterm Stage 2 shape. FoldState on the wire serves only semantic
(GPU) sessions. Staging reworked: Stage 2 = grid/daemon rendering, Stage
3 = wire-fed GPU.
F2: stored range pinned to the line-aligned hidden interior (head line
visible, closing-delimiter line hidden); one normalized form everywhere,
resolving the R1 5/7 contradiction.
F3: the store's edit-translation is the instance-side buffer-attached View
(BufferStyleSpanTranslator pattern, overlay.rs:235), which sees every real
edit — not the frontend-side translate_byte_range. Split the two resets:
per-session producer baseline vs per-buffer store lifecycle on content
replacement.
F4: stale-tree fold creation refuses with a message when
ParseViewHandle::current() is None or pending_edit_count() > 0.
F5: multi-frontend point + edit-vs-fold pinned — invoking point moves to
the head; interactive-point-inside edits unfold, programmatic/remote edits
translate; the no-cursor-inside invariant is creation-time-only in Stage 1.
F6: Lua data API takes an explicit buffer (no ambient resolution, per
#127) with full range validation, which is also what makes terminals
never fold.
F7: FoldState follows the authoritative-empty discipline; open-all emits
exactly one empty frame; the flipped pin test keeps asserting
BlockAdornments is never emitted.
Minors: source lines not display rows; close-all folds top-level only
(hs-hide-all parity); an injected-layer (markdown fence) acceptance added;
and an explicit note that FoldState needs no protocol bump.
The ledger inherited from #135's merge still listed Vterm Stage 3 as an
open 'never merge without authorization' implementation lane; it is merged
(main @ cac4961), so per the update protocol it moves to Closed and Arc 5's
terminal stage is marked complete. Adds the folding framing lane (branch
folding, off cac4961, framing-only) and points the canonical base at
cac4961 / protocol v19.
Draft framing for the folding arc, committed to the `folding` branch for
review before any implementation. Branch is cut from canonical main @
cac4961 (post Vterm Stage 3 #135).
The load-bearing finding: the bundled tree-sitter grammars ship no fold
query and no folds.scm — they export HIGHLIGHTS/INJECTIONS/LOCALS/TAGS
only. The roadmap's "tree-sitter fold ranges" premise is therefore not
free, so the fold source is a real decision (Q#FD1). The draft recommends
structural node folding (fold the nearest enclosing block-like node
spanning >= 2 rows), which reuses the existing parse trees for every
grammar and injection layer with zero per-language authoring; indentation
folding (grammarless fallback) and curated per-language queries (quality
pass) are deferred.
FoldState already exists in the protocol, declared but unproduced, with a
test pinning that it is never emitted; no frontend consumes it; gutter
markers are frontend-derived like the diagnostic sign bars, so no new wire
type is needed. Staged like vterm: Stage 1 engine (instance-side fold
model + structural source + Lua commands + FoldState production, headless),
Stage 2 TUI collapse+gutter, Stage 3 GPU at parity.
Numbered decisions Q#FD1-9, three falsifiable bets, named deferrals, and a
Stage 1 acceptance list. Awaiting review rounds; bindings (Q#FD4) and the
block-kind heuristic (Bet B1) are the two calls flagged for the user.
Record the approved managed-launch contract, daemon lifecycle and process-group rules, strict GPU CLI behavior, headless acceptance seam, and the complete acceptance matrix before implementation.
Advance canonical state to protocol v19, close the Vterm lane and roadmap arc, preserve the cross-PR integration lesson, mark PR #91 landed, and point machine-local housekeeping at the durable policy.
vterm-stage3-framing (superseded; content carried on vterm-gpu) and
tab-width-parity (merged via #137) were deleted with authorization —
worktree + local ref + githubsucks ref, origin tracking pruned. The
-framing branches for each are kept. Retires the now-dangling
superseded-lane recovery entry.
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.
PR #137 (tab-width-parity) is approved and frozen at 5b23e11. Neither
lane copies from or merges the other; whichever lands second rebases
onto the canonical resulting main and reruns the complete gate suite.
The overlap is pmacs-gpu/src/main.rs, pmacs-protocol/src/lib.rs,
Cargo.lock, and the two ledger docs. The lock and docs are mechanical;
the two source files are not — both PRs edit the GPU renderer's
measurement path and widen the protocol crate's export surface in the
same region, so a conflict-free apply is not evidence of a correct
merge.
One real defect, three cleanups, and a named deferral.
A daemon disconnect in terminal mode hid the disconnect notice. The
Disconnected arm set the placeholder text but never left terminal mode,
where the document code layer is not prepared at all and the terminal glyph
layer keeps painting its last frame — so the user was left looking at a
frozen, live-looking terminal that silently ignored input. GPU auto-reconnect
is a named deferral, so that state persisted until relaunch. State::
on_daemon_disconnected now leaves terminal mode, forces a repaint even when
the notice text is byte-identical, and requests a redraw.
The fix and its test share a file, so scripts/bite's file granularity cannot
bite it; the equivalent was done by hand. Neutralizing only the
exit_terminal_mode() call makes the test fail on the "must leave terminal
mode" assertion; restoring it makes it pass.
sync_semantic_terminal_layout no longer clones the whole visible cell grid to
read one size. It ran every dispatcher tick for any semantic frontend with a
declared terminal; TerminalManager::screen_size reads the value from the
borrowed projection instead.
Inbound terminal events now require a negotiated v19 session. The outbound
TerminalFrame was gated twice while TerminalResize/TerminalPointer relied on
the frontend's send gate alone. A pre-v19 peer cannot construct those
variants, so this only refuses a hand-rolled client — and the a32 forgery
tests already prove such an event reaches nothing but the sender's own
authenticated active view — but the asymmetry was not deliberate.
A terminal-mode press that misses the grid no longer arms a drag, so a later
in-grid motion cannot send a Drag with no preceding Down. Daemon-side impact
was nil; the state is now honest. A release still always ends the drag.
The roadmap and handoff Arc 5 lines still said Stage 3 was framed and
awaiting approval, contradicting this PR's own ledger. Both corrected.
Named deferral: terminal wheel gestures discard scroll magnitude. One winit
wheel event becomes one gesture regardless of the lines it accumulated, while
the document path scrolls by lines. Closing it means either N gestures
(chattier) or a magnitude field on the pointer event — a protocol change.
Neither belongs in this stage.
Gates: fmt; strict workspace clippy; 1,758 default + 1,934 CRDT library
tests; Stage 1 9/10, Stage 2 4/4, Stage 3 5/7, statusline 7/8
(default/CRDT); M4 120; required GPU 129; workspace sweep 2,923 across 83
suites; 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.
Five findings, all addressed. One was a real defect; one prediction did not
reproduce and is documented as such rather than papered over.
Hover no longer claims durable terminal control (finding 2, the real one).
apply_terminal_gesture claimed the controller before dispatching, including
for Move, which does nothing. A semantic frontend reports motion at pixel
rate, so sweeping the mouse across a passive split's terminal took durable
control, and the next layout sync resized the shared PTY to that background
view's geometry — precisely the theft the controller rule exists to prevent.
Bare motion no longer claims; every deliberate gesture still does.
scripts/bite HEAD src/editor.rs on the new test is a clean behavioral bite.
The terminal-mode presence-sweep skip is removed (finding 1), but the
predicted failure did NOT reproduce. The review reasoned that skipping the
sweep freezes last_broadcast at the abandoned document position. It does
not: the buffer-follow clears the terminal declaration when it ships the
snapshot, so terminal_active is false on the tick a window first shows a
terminal, and the declaration cannot arrive until a later tick — the
frontend learns the buffer id from that very snapshot. One truthful sweep
always lands first. The real-daemon two-frontend test written to catch the
freeze passes against the pre-fix tree; the bite is vacuous and the test is
labelled a regression guard, not fix evidence. The skip goes anyway: it was
load-bearing on tick ordering and bought nothing, and removing it makes
"presence follows the frontend" structural.
Terminal motion is deduplicated by cell (finding 3). Sub-cell motion
resolved to the same coordinate and still crossed the wire, where every
event is a daemon-side gesture. Press and release re-arm the memo so the
first drag after a press still reports. Its unit test cannot bite — the
seam did not exist pre-fix — and says so.
Declarations record only once sent (finding 4).
terminal_declaration_if_changed is now a pure query;
note_terminal_declaration_sent records. A failed write is retried instead of
suppressed as already-declared. The existing a35 test caught the contract
change and now pins both halves.
Unchanged frames skip revalidation (finding 5). The complete-payload
comparison runs before validate; only validated frames are ever stored, so a
frame equal to the baseline has already passed. The chrome tail is factored
into terminal_chrome so both exits emit it identically.
Gates: fmt; strict workspace clippy; 1,757 default + 1,933 CRDT library
tests; Stage 1 9/10, Stage 2 4/4, Stage 3 5/7, statusline 7/8
(default/CRDT); M4 120; required GPU 128; workspace sweep 2,921 across 83
suites; diff check clean.
Mark PR #134 as shipped in the durable handoff, framing, and side-quest
backlog. Remove the completed volatile lane and advance the canonical recovery
anchor to the merge commit.
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.
Gates: fmt; strict workspace clippy; 1,757 default + 1,933 CRDT library

Revision 8 of docs/vterm-framing.md was reviewed and approved on the
documentation branch vterm-stage3-framing. Stage 3 is implemented on this
branch, cut from canonical main, rather than stacked on that branch.
The framing locks additive protocol v19 (TerminalFrame, TerminalResize,
TerminalPointer), an 8 MiB aggregate glyph-byte bound under the unchanged
16 MiB transport cap, dual viewport declaration after every semantic
snapshot, authenticated per-view routing, and a fixed-cell native GPU
renderer. Criteria 28-37 are the scope of this branch.

Integrate landed Vterm Stage 2 before the approved modeline merge. Preserve the
active modeline lane in the volatile ledger and record the full integrated gate

Parse bounded Emacs and Vim modelines, normalize common aliases, and give
explicit file metadata precedence over inferred language. Pin one fresh-load
language decision for syntax, LSP, pairing, comments, and initial major mode,

Merges canonical main up to 2e37c04 and records the second of the two
arcs that landed while this lane was open. Vterm Stage 1 (#126) was
already recorded; this adds the config registry and reconciles every
claim the two merges falsified.
Handoff §1: main pointer moved to 2e37c04, and a config-registry entry
covering the parts a future agent cannot re-derive from the code --- the
always-store rule and why the "equal-value set is a no-op" reading
silently voids a buffer-local pin; the two-scope model and the
no-ambient-buffer contract on get(name); explicit-dispose-only listener
lifetime and the absence of any MetaMethod::Gc; the InitCompleteFlag
freeze that kept editor.rs untouched; and the strict-registry /
lenient-wrapper split that preserves trim_on_save("yes") and
interval_ms(1500.7).
Handoff §5 gains two lessons. Tab width is a rendering-parity bug, not
a config gap: five sites across two crates with two different values,
and no tab expansion at all on the GPU main text path, so
editor.tab-width is the obvious-looking first adopter and is not one.
And "a test that never runs passes" --- pmacs.editor.save() is the raw
save while buffer.before-save fires inside the buffer.save COMMAND, and
save() no-ops on an unmodified buffer, which made two review-round tests
vacuous until the buffer was dirtied and the command invoked.
Handoff §6: the three config-registry-blocked deferrals are resolved
(the per-buffer auto-pair toggle shipped as editing.auto-pair), replaced
by the registry's own named deferrals --- persistence, list-settings, a
settings completion source, table-valued settings, the unmigrated scalar
setters, and a scope = "global" flag, since set_local is currently
accepted for autosave.interval-ms where a per-buffer value is
meaningless.
active-work.md: base pointer and recovery assertion moved to 2e37c04;
the Vterm Stage 2 lane is told to cut from current main rather than
643d1e1; a closed-since-last-snapshot section records the merged lane
and the parallel-lane result --- two arcs in sibling worktrees with the
shared files assigned one lane each in advance rebased with zero
conflicts, which is worth repeating and states its precondition.
side-quest-backlog.md: both original north-star items have now shipped,
so the board is re-ranked to locals-query processing, mode-system wiring
(promoted --- every editor resolve still passes &[], making it the
largest remaining scoping gap), and tab-width parity. The config-registry
entry is struck and tab width is split out of it, since listing tab
width as a config consequence is what made it look like a cheap adopter.
Documentation only: the diff against main touches no runtime code.

Review round 1, findings 2-4 plus doc notes. Finding 1 landed in fd80bcb.
Finding 3 --- spec fields meaningless for the declared type are now
rejected. DEFINE_SPEC_FIELDS whitelists all nine keys for every type and
the kind parser only reads its own arm's fields, so
`{ type = "string", choices = {...} }` silently defined a string that
accepts anything (the author meant enum) and `min` on a boolean was
dropped. These are typo-shaped bugs the R50 whitelist structurally
cannot see: the key is spelled correctly, it is on the wrong type.
`check_fields_relevant_to_kind` closes it with a pointed error naming
the misplaced field, and a companion test pins that each field is still
accepted where it belongs, including `min`/`max` on number as well as
integer.
Finding 4 --- the after_buffer_removed purge had no end-to-end test.
Every existing test called ConfigRegistry::remove_buffer directly, so
deleting the three lines wired into mod.rs would have left the whole
suite green. The new acceptance test kills a buffer through
pmacs.buffer.remove (the real remove_buffer_and_fire route) and asserts
the locals are gone; bite-verified by removing the hunk and watching it
fail.
Finding 2 (the half with a natural buffer) --- editing.trim-on-save is
now resolved against the buffer being saved rather than the global
chain. Reading globally meant set_local was accepted, stored, and
reported by describe, then never consulted: a pin the user believes in
that does nothing, which is the shape F1 exists to prevent. Two tests,
one for the override and one for the global fallback the change could
have broken; the override test fails against the old global read.
Both new save tests initially passed VACUOUSLY and were rewritten:
pmacs.editor.save() is the raw save, while buffer.before-save fires
inside the buffer.save COMMAND (default.lua:224), and save() no-ops on
an unmodified buffer --- so the original form asserted on a file that
was never rewritten. They now insert content to dirty the buffer and go
through pmacs.command.invoke("buffer.save").
The other half of finding 2 --- a per-buffer autosave.interval-ms is
semantically meaningless yet still accepted --- is recorded as a named
deferral proposing a define-time `scope = "global"` flag, alongside
deferrals for bound-parse field naming and StartupOnly reset symmetry.
Also recorded: interval_ms(1e30) now raises instead of storing a
nonsense float, an improvement but a real divergence from "the wrapper's
shape stays exactly as it was".

A third registry beside CommandRegistry and HookRegistry, per
docs/config-registry-framing.md. Unblocks the per-buffer auto-pair
toggle, the first of the five backlog items the missing config surface
was gating.
Substrate (src/config_registry.rs):
* ConfigRegistry keyed by name with definition order preserved, R42
mandatory descriptions, R50 typo detection, duplicate rejection,
and SourceLocation provenance -- the command/hook vocabulary.
* Closed scalar kinds: boolean, integer, number, string, enum. Owned
Rust values; Lua tables, functions and userdata are never stored.
Integer exactness is checked by value, never math.type, so the
luajit and lua54 builds agree.
* Two scopes. get(name, buf) resolves buffer-local -> global ->
default; get(name) with no buffer resolves the global chain only
and never consults an ambient buffer. Buffer-locals live in a
registry-owned side table purged at after_buffer_removed, beside
the keymap purge already there.
* An override is ALWAYS stored, even when equal to the value it
shadows; only value_epoch and listener dispatch key on effective
change. Without this a buffer pinned to the current value stores
nothing and a later global set flips it -- the pin silently never
existed. equal_valued_local_override_is_still_stored_and_shields_buffer
fails against the naive reading.
Bindings (src/lua_bindings/config.rs):
* define/get/set/set_local/reset/is_set/describe/list/on_change.
Spec tables are read raw, so neither an unknown key nor a
metatable-provided value can smuggle a field in.
* Listeners commit inside the borrow, snapshot, drop the borrow, and
only then re-enter Lua -- verified by holding the borrow and
watching the test panic with "RefCell already borrowed". A raising
listener is logged without blocking later ones or rolling back, and
a depth bound turns an accidental cycle into a pointed error.
Listeners persist until explicitly disposed; there is no Gc path,
matching the rest of the codebase.
* StartupOnly freezes off the existing InitCompleteFlag at write
time, so this arc adds no editor.rs call at all.
Adopters, each defining its own key so SourceLocation names the owning
module: editing.auto-pair (pair.lua, read per-buffer against the typed
edit's SOURCE buffer), editing.trim-on-save (editops.lua),
autosave.interval-ms (autosave.lua). No public function is removed or
deprecated, and both migration wrappers keep their legacy coercion --
trim_on_save("yes") still enables, interval_ms(1500.7) still floors to
1500 -- coercing before handing the strict registry a conforming value.
M-x describe-setting renders into *help*, modeled on describe-command.
Framing revision 3 records four defects implementation found in the
document itself: acceptance 30 and 31 contradicted each other; the
planned builtin/runtime/config.lua had nothing to hold and would have
broken the source-location contract had it held the one helper it might
have; F5 asked define to police a call it cannot see, moved to
set_local; and list() ordering was underspecified.
No protocol change; SUPPORTED stays [6..18]. No wire surface. Zero
changes to src/editor.rs.

The cross-cutting substrate ranked first on the side-quest north star.
A third registry beside CommandRegistry and HookRegistry, with two
scopes (global and buffer-local), a closed scalar value vocabulary,
post-commit listeners, and no wire surface.
Ground truth established by scout at 7bc0c61, including three findings
that shaped the design:
* Tab width is five constants across two crates with two different
values -- four TAB_WIDTH = 8 in the daemon, 4 in the GPU minimap,
and no tab expansion at all on the GPU main text path. It is a
rendering-parity bug, not a config gap, so it is deferred to
stage 2 rather than made the proving adopter.
* The mode system is unwired: every editor KeymapStack::resolve
passes an empty active-modes slice. A mode scope would ship a knob
that silently never fires.
* load_user_config and set_init_complete both run inside
EditorState::new under one cfg(not(test)) block, so the
StartupOnly freeze point covers the daemon and local entry points
uniformly -- and never runs in --lib test builds.
Revision 2 records review round 1 (F1-F11). The load-bearing fix is
F1: an override is now always stored, with only value_epoch and
listener dispatch keyed on effective-value change. The prior
"equal-value set is a true no-op" reading meant an equal-valued
buffer-local override stored nothing, so a later global set would flip
the very buffer the user had pinned -- silently voiding the per-buffer
toggle this arc exists to deliver.
Also carried by revision 2: listener dispatch semantics pinned across
scopes, GC-collected listeners dropped (no MetaMethod::Gc precedent
exists), migration wrappers keep their legacy coercion, StartupOnly x
set_local rejected at define time, string-list dropped, describe's
`local` field renamed buffer_local (Lua keyword), and the direct-remove
leak corrected to permanent-but-non-aliasing since BufferIds are never
reused.
No implementation. Framing only.

Preserve PR #123's unpushed review fixes on a transfer branch: initial

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).

tests/gpu_font_acceptance.rs (items 2-7; the header manifest routes
item 1 to src/protocol.rs pins, item 8 to the src/frontend.rs TUI
drop unit, items 9-14/16-19 to pmacs-gpu's headless suite, and item
15 to the docs):
- 2: a fresh attachment's first frame carries the REAL (None, None)
default; unchanged ticks are silent; a late joiner receives the
current preference without post-attach mutation
- 3: a mid-session set_font emits exactly one FontFacts on the next
frame; an identical re-set advances the epoch without emitting
- 4 (producer half): on_buffer_snapshot_sent re-ships buffer facts
but never the bufferless FontFacts
- 5: real-daemon probe -- a v17 semantic session receives FontFacts,
a v16 peer never does (crdt feature)
- 6: the strict Lua contract -- 5.999/72.01/0/-16/NaN/inf/non-number
sizes error naming `size`; empty/non-string family errors
naming `family`; unknown keys rejected by name; hostile
__index/__pairs metatables never invoked and never inject
values; quantization pins 15.994->1599 / 15.996->1600 and both
boundaries; set_font {} resets both axes; the getter returns a
fresh quantized plain table; every rejected shape leaves the
preference and the wire untouched
- 7: a load_user_config_at fixture's init.lua set_font lands in the
handle installed before user config, and a pre-attach
preference ships on the first frame
Bites (mutate, observe the acceptance test fail, restore): the
Option-seeded first-frame send, the payload compare, the snapshot
survival of the font baselines, the v17 gate (BOTH halves widened --
producer for_peer alone leaks nothing because the daemon skip arm
still filters; the wire test only fails when belt AND braces are
cut), the unknown-key rejection, the range-check-original ordering,
and the raw_get metatable isolation.
Docs (item 15): docs/semantic-frontend-protocol.md gains the
FontFacts variant entry (v17 gate, authoritative default, no-pixels
preference relay, fail-closed receiver) and folds FontFacts into the
BufferSnapshot reset-contract paragraph (bufferless facts survive;
the frontend's caret-follow scroll residual is the buffer-scoped
part). docs/pmacs-gpu-design.md's "future customization needs no
wire-protocol changes" claim is corrected in place and points at the
framing as design of record; the Lua-override bullet now names the
landed set_font shape. The framing status bumps to implemented.

Post-merge handoff sync for multi-language injections (#122), folded
into the side-quest-backlog PR (rebased onto current main, which now
carries #120 themes stage 1 and #122 injections).
agent-handoff.md:
- §1: main head → 5e73966; add the #122 injection-engine entry (layered
ParseTreeBundle, worker-side layer building off the static grammar
table, settle-time query resolution, the new substrate — injections_query,
the alias snapshot, injection_capped, compute_highlight_spans_for, the
flatten event-sweep, the GPU fold — and the two hard-won findings).
- §6: the "multi-language injections" deferral is retired; replaced with
the real follow-ups (injection.combined, child-tree incrementality,
injectable Lua-registered languages, HTML/CSS/GraphQL/SQL consumer
grammars). Jupyter is now gated on JSON only.

Consolidate the non-themes backlog into docs/side-quest-backlog.md: an
exhaustive, deduplicated index compiled from every framing doc's
"Deferred (named)" section, the handoff §6 list, the roadmap arcs, and a
code-level marker sweep. Organized as side quests (one-shot-ish, led by
the highlighting/detection/LSP/editing families that continue the
#114–#118 stack), raid bosses (vterm, folding, DAP, GPU splits, Jupyter),
cross-cutting substrate blockers, and a prioritization north star.
Themes/faces/color items are excluded (they're the Arc 4 main quest) and
listed once so they're visibly accounted for. Handoff §6 gains a pointer
to it.
Docs only. git diff --check clean.
Two follow-ups + doc cleanup.
[P2] Same-depth sibling precedence was reversed. The wire priority was
(depth, capture_order), omitting the layer ordinal, so two overlapping
spans from different sibling layers tied — and the active-set insert
then applied the later one first, making the earlier sibling win, the
opposite of the grid's layer-by-layer paint. Priority is now
(layer_index, capture_order): layer_index is the depth-ascending
position in bundle.layers, so a deeper layer AND a later same-depth
sibling both override, matching the grid exactly. New
flatten_same_depth_sibling_later_layer_wins pins it.
[P2] Cap surfacing had no end-to-end test. Added
injection_cap_surfaced_once_and_rearms_via_lua, which drives the real
Lua settle path (syntax.lua tick -> _injection_capped -> pmacs.error)
and asserts surfaced-once, suppressed-on-unchanged-reparse, and
re-armed-after-dropping-below-then-exceeding-the-cap.
Docs:
- Q#IJ6 now states the accurate bound O(n log n + Sum active) for the
event sweep, not O(boundaries).
- The full-buffer perf test is renamed/narrowed to guard the FLATTENER
regression; the summary's per-line dominant-style tally is a separate
pre-existing O(lines x spans) loop, not claimed linear.
- Framing #9 now matches the test: it drives spans_from_segments (the
extracted replace_style_spans transform) + source_color_at, not a live
State render.

(1500-line rust) as the perf gate.
[P2] _parse_now used the empty alias map from make_request while
_dispatch snapshotted the registry map, so a `py` fence injected async
but not sync. Snapshot aliases on both paths; pinned by
sync_parse_now_resolves_alias.
[P2] The multi-range inline test used a one-line paragraph, whose block
inline node has no named children (link/emphasis are child-grammar
structures) — one range, so it couldn't falsify multi-range. Replaced
with a multi-line blockquote whose inline node carries a named
block_continuation: content_node_ranges now asserts >1 collected range
and emphasis parses on both lines.
[P2] The layer backstop dropped regions silently; the framing requires
a surfaced warning. run_parse now sets ParseTreeBundle::injection_capped;
syntax.lua's settle tick raises it once per buffer via pmacs.error
(_injection_capped). Added injection_layer_cap_surfaces_and_preserves_root
(drives >4096 fences, asserts the flag + bounded count + intact root).
Cleanup:
- The GPU acceptance test now drives the real StyleSpans full-frame
transform (spans_from_segments, extracted from replace_style_spans)
instead of a hand-rolled sort.
- content_node_ranges excludes NAMED children (documented as a round-1
refinement); framing mechanic #3 / Q#IJ5 updated to match.
- parse_duration doc now says root parse; the markdown entry no longer
describes inline as unhighlighted/future.

Frame the tree-sitter injection-layer engine: after the root parse,
run the grammar's injections.scm, parse each embedded region with the
injected language, and merge every layer's highlight spans. First
consumer is markdown fenced code + inline (zero new grammars).
Eleven numbered decisions (Q#IJ1-IJ11) and thirteen acceptance tests,
approved over three framing rounds. Load-bearing calls: the layer set
lives inside ParseTreeBundle installed atomically (Q#IJ1); a two-stage
worker/settle handoff keeps parsing off the main thread and query
caching in the Rc registry (Q#IJ2); recursion is depth/count/visited
bounded with child-only failure (Q#IJ3); a case-folded alias map
snapshotted into ParseRequest bridges Lua-set aliases to the worker
(Q#IJ4); included ranges are Vec<Range> excluding children and
intersected with the parent (Q#IJ5); the wire producer flattens layers
into disjoint effective spans because the GPU re-sorts by start, and
the GPU first-span consumer is fixed to fold (Q#IJ6).

The round-4 freeze read counted the retained for_uri vector inside
status_facts_msg -- correct, but StatusFacts runs at frame cadence
for every semantic session under the shared store mutex, so a long
stale interval cost O(frames x diagnostics x sessions).
DiagnosticStore now maintains per-URI severity totals alongside
by_uri: set replaces them (an empty publication removes them with
the vector), clear removes them, and mark_stale deliberately
preserves both -- entries exist exactly when by_uri entries do, and
set/clear are the store's only by_uri mutators. status_facts_msg
reads the tuple in O(1), and the all-URI severity_totals sum reuses
the cached tuples.
Store unit (acceptance item 34) pins the invariant: all four totals
replace correctly, survive staleness, and clear with the diagnostic
vector; empty_set_clears_uri asserts the totals drop too. The
rounds 3-4 freeze acceptance passes unchanged -- behavior parity,
so the unit pin is the evidence (no runtime bite exists for a
behavior-preserving refactor). Round-5 implementation
user-authored; this commit folds it with framing revision 9, the
protocol doc's O(1) note, and the acceptance manifest pointer to
the item-34 unit.

A session first rendering during diagnostic staleness emitted zero
counts: round 3's frozen_diag_counts cache was per-session and only
seeded from fresh computations, so a late joiner attaching mid-edit
(or a buffer first visited between didChange and fresh diagnostics)
had no entry and fell back to (0, 0), contradicting the documented
"frozen counts, never zeros" contract.
mark_stale (T M11.8) keeps the last published diagnostic vector --
only the positions are invalid -- so status_facts_msg now counts
the retained for_uri entries even while stale: the retained entries
ARE the frozen value. The per-session cache is deleted; sourcing
the freeze from the store means there is no session state to lose
to a snapshot reset and no history needed at attach, so the round-3
reset-survival property holds by construction and its round-trip
test passes unchanged against the new mechanism.
Acceptance item 33 marks a populated store stale BEFORE the
SemanticRenderState exists and asserts the first frame reports the
preserved counts; runtime bite vs pre-fix semantic_render.rs.
Framing revision 8; the protocol doc's freeze sentence now says
store knowledge, including the late-joiner case.

Finding 1: the round-2 reset contract was asymmetric. The producer
resets search/menu/status baselines on every snapshot send, but the
GPU's BufferSnapshot arm only cleared spans, decorations,
adornments, summary, and the completion popup -- a menu or search
open at switch time survived the snapshot with no close message
ever coming (the new buffer's first CLOSED state is suppressed
daemon-side), leaving a stale popup that also held
daemon_intercepts_keys true and swallowed pointer events
indefinitely. The arm now clears search_prompt, menu, and
status_facts; the minibuffer is deliberately exempt on both sides
(one global core instance, matching the producer's surviving
last_minibuffer baseline). GPU test opens search + menu + status
via the real wire arms, applies a snapshot, and asserts all three
clear, the intercept gate releases, and the popup pixels vanish --
hand-bitten by disabling the three clears (fix and test share
main.rs).
Finding 2: the round-2 reset broke the diagnostic-count freeze.
last_status was both the peer emission baseline and the
stale-store freeze source, so a snapshot between didChange and
fresh diagnostics re-shipped StatusFacts with zeroed counts. The
freeze source now lives apart: frozen_diag_counts advances on every
fresh count, is read when the store is stale, and survives
on_buffer_snapshot_sent -- which keeps killing the emission
baseline to force the re-send. Acceptance renders (1,1), marks the
store stale, applies the reset, and asserts the re-sent StatusFacts
still carries (1,1); runtime bite vs pre-fix semantic_render.rs
fails exactly as predicted (Some((0,0)) vs Some((1,1))).
Framing revision 7; acceptance items 31-32; the protocol doc's
snapshot-reset paragraph now lists the full frontend drop set and
names the count freeze as daemon knowledge, not peer state.

Finding 1: a BufferSnapshot wipes the frontend's buffer-scoped
render state (spans, decorations, adornments, minimap summary,
completion popup), but the producer's per-buffer emission baselines
survived the switch -- on an unchanged A -> B -> A round trip,
last_summary[A]'s key still matched and the daemon emitted nothing,
so the frontend never regained A's themed minimap (or A's
StatusFacts: the band kept B's name) until an edit, republish, or
theme mutation happened to move the key.
The fix is the general contract, not a minimap special case:
SemanticRenderState::on_buffer_snapshot_sent(buffer_id) kills every
buffer-scoped baseline for that buffer (spans + style gate,
decorations, adornments, summary, status, search/menu prompts,
completion popup), called wherever the daemon writes a snapshot --
the active-buffer-follow path and the F29 upgrade broadcast; the
attach bootstrap constructs its session state fresh. Deliberately
surviving: the bufferless ThemeFacts pair, the global minibuffer
baseline, the per-frontend gutter mode, the revision-keyed diag
line cache, and other buffers' baselines.
Evidence: a producer round-trip acceptance test (themed summary and
StatusFacts return at the SAME generation; identical payload), a
real-daemon wire test driving A -> B -> A via dispatched keys
(runtime bite: times out against pre-fix daemon.rs), a Rust unit
pinning the reset's scope, and a GPU test where the re-shipped
summary restores the first visit's pixels exactly (frontend half --
no GPU code change, coverage only). The semantic_render.rs bite is
compile-fail (the hook is absent pre-fix), disclosed as weaker.
The protocol doc's composition section now states the snapshot
reset contract on both sides of the wire.
Finding 2: the acceptance-suite manifest header now lists the true
item split (1-19, 24-26, 28-29 here; 20-23, 27, 30 in the GPU
suite). Framing revision 6 folds the round; acceptance items 28-30.

Finding 1: accepting a FileStyleSummary drops the GPU minimap vertex
cache -- theme recolors and diagnostic republishes arrive at an
unchanged generation, and the cache keys only on (generation, dims,
scroll), so stale strokes survived until an edit/resize/scroll. The
daemon payload-suppresses identical summaries, so the invalidation
is precise. GPU test drives two same-generation summaries;
hand-bitten by reverting the single invalidation line (script-bite
is vacuous here: fix and test share main.rs).
Finding 2: lua_to_style propagates every Table::get error -- the
lookups run __index, so a raising metatable previously parsed as an
all-default style and the merge SUCCEEDED, committing valid siblings
against the Q#TH6 all-or-nothing contract. Boolean fields keep Lua
truthiness by design (mlua bool), so only raising lookups fail the
transaction. Acceptance reproduces the reviewer's trap shape;
runtime bite vs pre-fix mod.rs.
Finding 3: SemanticRenderState::for_peer records the negotiated
version; below v16 no ThemeFacts is produced and no ui.diag.* face
folds into the FileStyleSummary marks -- the summary is an ungated
pre-v16 channel, and a v15 peer must not get face-derived minimap
colors while its other severity surfaces stay unthemed. The summary
cache key zeroes its face-epoch component for such peers. Acceptance
drives v15/v16 producers side by side; compile-fail bite disclosed
(the test needs for_peer, absent pre-fix).
Finding 4: framing revision 5 weakens the canonical-severity claim
to what is true -- the daemon-RESOLVED color is canonical, while the
GPU's built-in squiggle/sign/counter defaults are historical bright
RGBs that differ from the minimap's converted Indexed marks, a
pre-existing divergence kept because unset faces must render
byte-identically to before.

- §1: `main` @ 7d1b6d6; new arc bullet covering the grammars (every
LSP-configured language now has one), the extension → filetype →
filename → shebang detection chain and its user-extensible Lua
surfaces, the dockerfile/cmake LSP configs, and the substrate
(`highlights_query: &[&str]` base-first composition; fail-closed
`#is?`/`#is-not? local` handling in `compute_highlight_spans`).
Condensed the merged compile-mode/editops/auto-pairing blocks to
substrate essentials. Fixed the stale "#114 is the USER'S lane" note:
themes (Arc 4) is the user's active `theme-faces` lane.
- §3: folded the confirmed flakes (m6_1_pty, composition_overhead) into
the rerun-isolated note, plus the single-invocation sweep caveat.
- §6: new deferrals — locals-query processing, multi-language
injections (blocks notebooks / markdown code / HTML-in-JS), modeline
detection, JSON/YAML, byte-accurate cursor; a full Jupyter setup is a
real arc, not a one-shot.
Docs only. #118 is approved, merge pending. git diff --check clean.
Syntax.rs theme-handle line refs re-verified; the new shell grammar
introduces no ui-named capture, so the Q#TH2 reservation holds.

Arc 4 stage 1 (docs/theme-faces-framing.md, revision 4). Faces are
theme entries under the reserved ui/ui.* namespace -- zero new Lua
API. Theme::face() resolves with the dotted-prefix walk but never
falls back to default_style; each face applies owns-surface within
its stage-1 component mask, identical on both frontends.
Substrate: two monotonic theme mutation counters (syntax/face) with
transactional set/merge/clear/default (parse before locking, commit
all-or-nothing, bump from the prior value); the StyleGate and the
minimap summary key on the counters -- fixing the pre-existing bug
where a mid-session pmacs.theme.set never re-shipped StyleSpans --
with the summary gaining payload-equality suppression that still
advances its key on computation.
Wire: InstanceMessage::ThemeFacts appended after CompletionPopup
(postcard discriminants are ordinal; a byte pin guards placement),
PROTOCOL_VERSION 15 -> 16, daemon-gated >= 16, one authoritative
table per attachment (None-seeded baselines), TUI silent-drop arm.
Grid: paint_frame resolves ui.modeline / ui.statusline /
ui.minibuffer(.candidate) / ui.gutter / ui.selection faces;
SearchView and DiagnosticView take the theme handle through the real
attachment paths (EditorCore injection, install_diag threading); the
canonical severity color resolves ui.diag.* with the Default ->
built-in policy that keeps the minimap presence encoding sound.
GPU: exact-name face table applied per draw with the Q#TH5 Default
mapping (plain text / window bg, reverse swap), local/peer wash
split, candidate-dropdown glyph site, and the status-band
shaping-cache invalidation without which a diag-face recolor with
constant counts kept stale counter colors.
Tests: 18-test acceptance suite (grid, wire, daemon gate, atomicity,
monotonicity, late join), 7 GPU headless tests incl. decoded vertex
colors, units for the face walk / transactional commits / producer
caches; protocol pins for v16 + the CompletionPopup byte pin.
Bites vs 3cbb9de (scripts/bite): semantic_render.rs (8 runtime test
failures), editor.rs (5 runtime), daemon.rs (v15 gate, runtime);
lua_bindings/mod.rs, pmacs-gpu/main.rs, search.rs, diag.rs, and
highlight.rs bite as compile failures (weaker evidence, disclosed).

Finding-by-finding (framing revision 13; bites via scripts/bite
against fe04aa4):
1. attach_style_overlay validates the handle. A handle's translator
follows edits to ITS buffer only, so attaching it to another
buffer created a render view showing spans nobody maintains —
rejected now, with the message naming the recorded owner and
pointing at add_style_overlay for the target buffer. A disposed
handle's translator is gone, so re-attachment resurrected
rendering with frozen coordinates — the disposed state is shared
across handle clones (FromLua clones) via Arc<AtomicBool> and
attachment after dispose() fails, pointing at add_style_overlay
for a fresh handle. Bite: r7f1 pins cross-buffer rejection,
same-buffer acceptance, dispose-then-attach rejection, and both
message shapes.
2. dispose() detaches the translator through the always-registered
SharedRegistry; only the window cleanup rides the optional
SharedCore. Pre-fix all cleanup lived inside the SharedCore
branch, so an install-only/headless host got success with the
translator left attached — paying on every edit for the buffer's
lifetime. Registry-only unit asserts the buffer's view count
returns to baseline (and stays there on double dispose); the
acceptance-crate twin r7f2 builds the same install-only host and
bites via the mod.rs swap (the in-crate unit vanishes with it).

Finding-by-finding (framing revision 12; bites via scripts/bite
against a49adc2):
1. Render-view attachment is idempotent and split-complete. Overlays
expose overlay_identity (the span store's allocation address);
Window::ensure_overlay attaches a store-backed render view AT
MOST once per window — pre-fix every switch into the buffer
blindly pushed another copy onto EVERY matching window, so
passive panes accumulated duplicates, each cloning all spans and
rescanning the buffer per frame. A same-buffer split copies
clonable overlays to the new pane via clone_for_split (splits
fire no switch hook and started with an empty overlay list — the
new compilation pane rendered unstyled). Bites: the acceptance
test asserts both panes styled with exactly one attachment
IMMEDIATELY post-split (before any switch could heal the pane
through the attach-to-all path — the first draft asserted only
after bouncing and was vacuous against the split fix), then
re-asserts after three bounce cycles; fails against pre-fix
editor_core.rs (split half) and pre-fix mod.rs (accumulation
half) independently. Units pin ensure-once and split-copy/no-copy.
2. The translator ignores pure no-op edits (buffers deliberately
broadcast empty inserts/deletes for callers that count calls):
pre-fix each interior no-op split the containing span into two
adjacent fragments — unbounded list growth for repeated no-ops at
distinct positions, and a no-op at a UTF-8 continuation byte
minted a mid-codepoint span boundary. Units now cover genuine
EditOp::Insert (the round-5 "insertion" unit only replaced) and
no-ops at five interior positions including the continuation
byte; the Lua twin (r6f2) bites via the overlay.rs swap — as a
compile failure, since that file also carries the round-6
identity machinery (weaker evidence, per the bite script's
caveat; the in-crate unit pins the behavior directly).
3. StyleOverlayHandleLua retains the buffer and translator ViewId
and exposes idempotent dispose(): detaches the buffer-attached
translator (later edits stop paying for it) and removes every
window render view over the store. Documented lifetime contract:
one handle per buffer incarnation (the compile/REPL discipline)
needs no disposal — the buffer's death frees it; repeated
creation on a long-lived buffer must dispose retired handles.
Bite: r6f3 (translate → dispose → edit must NOT move the span,
render views gone, double-dispose safe) fails against pre-fix
mod.rs.

Finding-by-finding (framing revision 11; bites via scripts/bite
against 6793edc):
1. Style-span coordinate translation belongs to the BUFFER. A new
BufferStyleSpanTranslator is attached by
pmacs.buffer.add_style_overlay and sees every edit exactly once —
bypass writes, undo/redo, remote CRDT ops — independent of window
count or visibility; the window-attached BufferStyleOverlay
copies are render-only (on_edit removed). Pre-fix each attached
view translated the shared store: start_run's explicit attach
duplicated the after-switch hook's (switch_buffer fires it
synchronously), so the normal path shifted later spans TWICE per
byte-delta rewrite, splits multiplied further, and a hidden
buffer shifted ZERO times. The redundant attach is removed;
correctness no longer depends on attachment discipline. Bites:
per-cell rendered assertions active (red a, blue bc, CR, red é →
é red, b/c blue) and hidden (run finishes with the buffer in no
window; switch back renders true colors); three direct units pin
exactly-once with extra render views attached.
2. Translation preserves the untouched fragments of a partially
overlapped span: left of the replaced range keeps its styling,
right of it shifts by the length delta, only the rewritten bytes
lose theirs (the writer styles what it writes; inserted bytes
inherit nothing). Pre-fix any overlap dropped the WHOLE span —
red abc, SGR reset, CR, X left bc unstyled; zero translation
painted the default X red instead. Bite: exact (glyph, fg) cells
X=default, b/c=red — any_styled_cell cannot see either failure.
3. The per-CR/BS/erase-line whole-prefix scan is gone:
slot.line_start is tracked — advanced at every \n (append helper
+ the mid-line newline branch), read O(1) by the rewind paths,
reset on run start/resync/raw marker appends. Measured on 2 MB of
output + 3000 CR updates (release): 2.52s pre-fix → 0.67s
post-fix (remainder is fixture-bound; pre-fix cost grows with
buffer size). No correctness bite is possible for a pure perf fix
— the committed test pins the tracked value's behavior across
multi-line appends, batch-boundary CR, repeated CR, erase-line,
and recovery paths, and passes on both implementations by design.

Finding-by-finding (framing revision 10; bites via scripts/bite
against b5bbce8):
1. CR rewrites are COLUMN-counted and newline-segmented, not
byte-counted. Each newline-free segment of a text event consumes
one existing codepoint per incoming codepoint (codepoints
approximate columns; double-width and combining characters count
as one — the documented stance), and LF is not an overwrite
column: a newline arriving mid-line drops the cursor to a fresh
line and the stale remainder survives in place (terminal
semantics). Pre-fix, abcdef\rX\n wrote "X\n" over "ab" — splitting
the line and leaving "cdef" as a ghost line the parser saw again
at EOF — and abc\ré ate two ASCII columns because é is two bytes.
Round-3's UTF-8 invariant holds per-segment: every edit's range
ends sit on codepoint boundaries, so the rope is valid after each
step and byte-native CRDT edits never reject. Bites: single-batch
(shorter rewrite, multibyte-over-ASCII, CRLF), split-feed with the
é split across batches, and a CRDT twin covering the segmented
multi-edit replication.
2. Alternate-screen exits resynchronize the effective style. The
parser now tracks the style the consumer LAST RECEIVED
(emitted_style; outside alt-screen it always equals
current_style). An ordinary ?1049l exit emits the resync SetStyle
whenever suppressed SGR changes drifted the two apart, and
finish() balances against emitted_style rather than
current_style — a suppressed SGR reset inside the alt screen left
the internal style default, so the old comparison saw nothing to
balance while the consumer stayed red. Consumer-mirror units for
both drift directions plus the no-drift no-event case; Lua twin
(r4f2) bites via the ansi.rs swap.

Finding-by-finding (framing revision 9; bites via scripts/bite):
1. The CR/backspace renderer is UTF-8-safe: overwrite ranges consume
WHOLE existing codepoints (range end aligned forward past
continuation bytes) in ONE atomic replace of the complete text
event — never a split of either side — and backspace steps to the
previous codepoint boundary; out_pos stays on boundaries by
induction. Pre-fix, byte-counted splits left malformed bytes on
the plain rope, and under CRDT the byte-native edit rejected the
mid-codepoint range, aborting the pump after events_take had
consumed the batch (terminal event lost, record leaked). Bites:
default acceptance (é\rX, X\ré, é\bX with exact-content, marker,
clean-*errors*, baseline asserts) and a CRDT twin that pre-fix
times out never reaching its exit marker.
2. parser:finish()'s reset is observable: balancing events —
AlternateScreenExit for an unclosed enter, a default SetStyle for
a non-default running style (now also cleared; reset() preserved
it) — let consumers unwind mirrored state from the event stream
alone. New Rust unit applies events to consumer state; Lua twin
(r3f2) bites via the ansi.rs swap.
3. stdin/group spec fields are RAW reads: spec tables are plain
data, metatable-provided fields are deliberately not honored (the
compile.lua rawget posture), and a raising __index can no longer
be silently absorbed as group=false, quietly disabling
process-group isolation. Regression test pins both shapes:
metatable-provided group=true is ignored (pgid != pid), and a
hostile raising metatable spawns cleanly.

Finding-by-finding (framing revision 8; bites via scripts/bite):
1. Rule validation is a stable, total snapshot: validated scalar
fields are copied into per-run plain tables via raw reads
(rawget; metatable-provided fields deliberately not honored), so
post-run mutation of the user's rule objects cannot alter an
in-flight run and a hostile __index is a counted skip, not an
error thrown through the pump mid-batch. The container traversal
is itself pcall-protected; traversal-raise semantics are
Lua-flavor-dependent (5.2+ ipairs consults __index, LuaJIT reads
raw) and the test pins both flavors.
2. Capture indexes must be FINITE (floor(math.huge) == math.huge, so
integrality alone passed it); math.huge is now a counted
malformed entry.
3. Shell-command never touches the rule table: no spurious
compile-rule warnings on M-!, and no rule-container state can
block a run that performs no parsing.
4. AnsiParser::finish() (and parser:finish()) now fully resets the
parser — in-flight CSI/OSC/escape state and alt-screen
suppression included — so a post-finish feed parses a fresh
stream. Three direct unit tests in ansi.rs plus a Lua-driven twin
in the acceptance suite (the twin exists because a scripts/bite
file swap replaces the in-file units along with the fix).
5. Comment corrections: fractional capture indexes read a distinct
absent key (not a neighboring capture); the group-coercion
comment describes truthiness, not false; the AnsiParserLua
rustdoc lists finish().

Finding-by-finding (framing revision 7; every fix bite-verified via
scripts/bite against the pre-fix tree):
1. Stored coordinates must be finite integers, and both cursor walks
are movement-bounded — they clamp at EOF, and the column walk
clamps at the target row's EOL instead of marching onto later
rows. An astronomical %d+ capture can no longer hang the editor.
2. The grep panel gains the same immediate buffer.after-edit
recovery trigger as the compile slots: M-x buffer.undo after a
COMPLETED search is marked synchronously.
3. The rustc arrow rule uses the framing's ([^:]+) spelling — paths
with spaces capture whole.
4. All pattern captures are collected (index 4+ reads the real
capture, not nil-as-column-0); capture indexes must be positive
integers; a rule naming a column its match didn't produce rejects
the match.
5. emit_text_raw is module-local — a user global could shadow the
helper the terminal-event path depends on, and its error consumed
the terminal event before pump cleanup/forget ran.
6. stdin/group spec fields reject wrong Lua types as hard errors;
group is matched as a raw Value because mlua's bool conversion
applies Lua truthiness ("true" would silently coerce).
7. resync also nils the public line_start_byte — total pre-marker
anchor invalidation includes the byte anchor.
8. The inherited cwd resolves through
pmacs.instance.identity().working_directory; the header always
names a real path and relative error files get an explicit base.
9. New AnsiParser::finish() + parser:finish() (additions #5): a
truncated multibyte sequence at process EOF surfaces as U+FFFD
before the exit marker instead of vanishing.
10. The built-in default rules are a private deep copy — in-place
mutations of the public table no longer survive the "using
built-in defaults" degradation.
Eleven new tests (r1f1a/b–r1f10); bites: 9 fail against pre-fix
compile.lua, r1f2 against pre-fix default.lua, r1f6 against pre-fix
lua_bindings/mod.rs — all clean assertion failures. Gates: fmt,
clippy workspace all-targets, lib 1522, crdt lib 1696, compile
acceptance 45, crdt acceptance 1, m4 101, GPU 59, workspace sweep
2493/0, git diff --check.

cargo fmt over the new files; doc-markdown backticks; is_ok_and in
the recompile counter wait; m4_6's M-g n/p pin updated to the Q#CM5
takeover contract (error.next/error.previous with the diag commands
as the dispatchers' fallback — the test's no-attachment status
behavior is unchanged). Handoff §1: main @ 0efb5cd, compile-mode
branch in flight at framing revision 6, themes named as the
standing runner-up.

Revision 6 after five pre-branch review rounds. Scope: M-x-style
compile.run with a streaming *compilation* buffer and error-regex
navigation; grep-mode as an upgrade of project.search; M-! shell
command. Shared machinery: streaming intercept-read-only output
buffer with a revision-guarded external-edit recovery protocol, and
a claim-based error-source dispatcher with diagnostics fallback.
Supervisor additions: stdin="null" and group=true pipe-mode spec
options — the latter a full lifecycle policy (process_group(0)
spawn, group-directed signals, liveness-probed TERM-to-KILL reap
ledger integrated into shutdown, bounded in-drain enforcement,
poll-based cancellable readers). Binding additions: buf:revision(),
jump_back buffer.after-switch parity.

A trap-guarded one-file swap over read-only git show: run the named
tests against an older version of one file and exit 0 iff they FAIL
there (the fix bites); exit 1 flags a vacuous fix. The file is
restored on every exit path including interrupts; the ./ pathspec
prefix makes it work from any directory inside the repo. Never
touches git stash — the stash namespace is repo-global, shared
across worktrees and with humans (a #111-round mishap popped a
PR-#17-era user stash; hence the tool).
Dogfooded three ways against the merged #111 history: the round-1
fix commit bites (exit 0), the same tests against HEAD read as
vacuous (exit 1), and a docs/-relative invocation restores cleanly.
Handoff: section 1 snapshot (editops #111 merged, worktree folded),
section 5 lessons (repo-global stash; worktree-per-lane for
parallel work).
