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().
Bites: r2f1 (both shapes), r2f2, r2f3 fail against pre-fix
compile.lua; r2f4 fails against pre-fix ansi.rs. Gates: fmt, clippy

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.run with a streaming *compilation* buffer and error-regex

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),

Finding 1: codepoint recognition is now full UTF-8 scalar validation
(shared second-byte constraint table: overlongs, surrogates, and
beyond-U+10FFFF all fail), and transpose validates the scalar AT the
cursor trailing-bytes-included — a valid lead with non-continuation
trailing bytes fails closed, as does a length-consistent overlong or
out-of-range span behind the cursor. Zap's single-codepoint check
uses the same validator as defense-in-depth (minibuffer contents
arrive as Rust-side UTF-8; the buffer-facing checks are the
load-bearing ones).
Finding 2: capitalize is per-word across the span — Emacs
capitalize-region parity, verified against Emacs 30.2 ("hello WORLD"
-> "Hello World", "9abc a9bc" -> "9abc A9bc"); the one remaining
deviation is named and pinned: `_` is a word constituent in this
pack's ASCII class, so "foo_bar" -> "Foo_bar" versus Emacs's
"Foo_Bar".
Finding 3: an unexpected error caught by the trim-on-save outer
pcall is no longer discarded — it reports on the status line AND the
*errors* buffer via pmacs.error (the autosave sweep convention),
both pcall'd, still never vetoing the save.
All three fixes bite-verified: the five new/updated acceptance cases
fail against the pre-fix editops.lua (72 total now). Framing at

Coverage pins only, no code changes.
Finding 1 (low): the predicate's raw-byte posture is now pinned from
the buffer side — `(` typed immediately before a lone 0xFF inserts no
closer. Verified non-vacuous: reverting char_at to nil-on-malformed
makes the test fail (nil reads as end-of-buffer and pairs before the
junk).
Finding 2 (low): the top-level container guard is pinned alongside
the per-entry cases — `pmacs.pair.sets = 42` pairs nothing and leaves
*errors* clean.

Finding 1 (medium): pair entries validate full UTF-8 well-formedness
(Unicode Table 3-7), not just lead-byte length — continuation-byte
shape on every trailing byte, overlong encodings (C0/C1, E0 80-9F,
F0 80-8F), UTF-16 surrogates (ED A0-BF), and beyond-U+10FFFF (F5+,
F4 90+) all disqualify, so "(\xC2x" can no longer inject invalid
bytes as a closer. char_at shares the validator and returns the raw
byte for malformed buffer content: the predicate treats junk as
word-like (no pairing before it), never as EOL. Bite:
malformed_utf8_pair_entries_are_rejected (four ill-formed shapes).
Finding 2 (low): relevance and reporting resolve against the SOURCE
buffer the record names, not whatever buffer a context-switching
command left active. New pmacs.lsp.buffer_language(buf) is the
parameterized primitive (active_buffer_language delegates), backed by
a new buf:path() query on buffer handles. Bites: rust→python `'` now
stays silent; python→rust `'` now reports "source context changed".
Finding 3 (low): non-table set containers degrade
language→default→empty instead of throwing from the after-edit
callback on every keystroke. Bites: a string default pairs nothing
with a clean *errors* buffer; a junk language entry falls back to the
default set.

Finding 1 (medium): the typed-edit record now pins the edited
buffer's revision after the completing edit; typed_edit_finish
re-reads it at dispatch end and drops the record if the command
edited again — a redefined buffer.self-insert that replaces the typed
char (cursor unmoved) no longer leaves a stale-but-clean record, so
`(`-then-replace-with-`[` yields `[`, not `[)`. Bite:
post_insert_mutation_by_the_command_kills_the_record.
Finding 2 (medium): pair-set relevance is established before the
clean/context gates, so a transformed or relocated character outside
the active set stays silent instead of drawing an auto-pair report.
Bite: transformed_non_pair_char_stays_silent.
Finding 3 (medium): split_pair parses EXACTLY two codepoints and
rejects trailing bytes — a "()x" (or "«»x") entry is skipped
entirely, never honored as `(` → `)x`; valid multibyte pairs ("«»")
pair and skip at byte-correct cursors. Bites:
malformed_pair_entries_are_skipped_not_partially_honored,
multibyte_pair_entries_pair_and_skip.
Finding 4 (low): the record-capture seam is gated behind the opt-in
pmacs.pair._capture_records test facility, off by default — no
consumed record is retained in production, restoring the Q#AP9
ephemerality the seam had defeated. Seam-reading tests opt in;
record_capture_is_off_by_default pins the default.
Finding 5 (low): the equal-revision source-context-switch twin is
covered — the fan-out is skipped by the active-buffer revision
compare, pairing fails closed silently, and no report is possible;
the framing scopes the context-change report as best-effort until the
buffer-aware edit epoch lands.
Framing synced to revision 4 (Q#AP2 entry rule, Q#AP3 relevance-first
+ best-effort report scope, Q#AP9 revision postcondition + capture
facility + the dispatch-path intercept borrow note, acceptance list).

Finding 1: the empty-anchor optimistic residual was never GPU-only
(the TUI mirror tracks no selection state; its gate checks cursor
freshness/EOL only). The fix moves daemon-side: handle_remote_crdt_op
clears a selection whose anchor equals the pre-edit cursor (= empty)
before applying the source cursor update; nonempty selections stand.
Covers both frontends. The TUI gate's missing type-over check
(nonempty selection at EOL) is a named deferral.
Finding 2: Q#AI8 invalidation is one helper
(search_invalidate_for_edit) invoked from all four edit paths --
apply_active_edit, notify_buffer_edit, and now undo/redo, which
received precise Edits but invalidated nothing. rebuild_views_for is
named as a lower-frequency bypass (deferral).
Finding 3: acceptance matrix trued up -- added active-search
fail-closed + retype recovery, delete translation on both paths,
undo/redo staleness + origin tests; modal contexts narrowed to what
this suite pins (query-replace/menu/completion ride their own
suites).
Finding 4: indent extraction is a forward-chunked scan stopping at
the first non-whitespace byte -- Enter at the end of a giant
minified line no longer materializes the line. Functional pin at
64 KiB.
Both medium fixes are bite-verified (tests fail with the fix
disabled).

RET now runs edit.newline-and-indent (builtin/runtime/indent.lua):
one insert/replace of "\n" plus the current line's leading whitespace,
copied verbatim and clipped at the split point (Q#AI3). Region RET
stays a single Replace (CUA type-over, one undo step, one CRDT op);
the selection clears after every successful edit (Q#AI4). Fix-up is
snapshot-guarded against context-switching intercepts and repairs the
cursor by right-gravity translation through the effective edit
(Q#AI5). buffer.newline remains the plain-newline escape hatch.
GPU (Q#AI1/Q#AI6): plain Enter is no longer optimistic-eligible --
its classifier arm's premise (byte-identical to a self-insert) died
with the new binding. Enter round-trips like the TUI, which also
makes global and buffer-local RET rebindings (buffer-list visit)
reachable from the GPU frontend.
Substrate fixes that RET would otherwise ship on top of:
- Q#AI8 search staleness: notify_buffer_edit now marks matches stale
and right-gravity-translates the live session origin, matching
apply_active_edit; SearchStore::step and search_match_summary fail
closed while stale (a live search un-sticks on the next pattern
keystroke, since set() clears staleness).
- Q#AI9 empty selections: insert_char reports success and the
no-region arm of insert_char_over_region clears a lingering anchor
only on Ok -- ordinary typing no longer type-overs its own previous
keystroke after S-Left at BOF, and a rejected insert mutates no
state.
Acceptance: tests/auto_indent_acceptance.rs (20 dispatch-driven
cases), tests/auto_indent_crdt_acceptance.rs (pending optimistic
input then round-tripped Enter converges on the source replica),
flipped GPU classifier test, and lib tests for the store, core, and

Addresses the PR #100 review round 4.
- MEDIUM stale skip-cache entry after a slot transfer. adopt() set
owner[hash] = new buffer but left the previous owner's `written` entry
pointing at the same hash, breaking the invariant
`written[id] => owner[hash] == id`. Repro: A and B are duplicate buffers
on one path; A owns the slot; B adopts (recover-file); B is killed
without saving, which frees the slot and deletes the file. A is still
dirty, but its stale written[A] = (hash, revA) makes the next sweep call
it "unchanged since its last copy" --- silently unprotected until its
next edit. adopt() now drops any other buffer's written entry for that
hash. Verified the new test fails without the fix (sweep writes 0).
- MEDIUM autosave write failures were swallowed. write_private can fail
(ENOSPC, a permission change, a clobbered state dir), but the tick and
before-quit paths did `pcall(sweep)` and dropped the error. For a
data-protection feature that is the worst failure mode: the user keeps
working, believing edits are captured, while nothing is written. Both
paths now go through a reporting wrapper --- status line "autosave
FAILED: ... --- your work is NOT being protected" on every failing sweep,
each distinct fault logged once via pmacs.error. The quit path reports
too (a failure there means the quit is about to discard work that was
never written anywhere) and still never vetoes.

Addresses the PR #100 review round 3.
pmacs.buffer.from_file does not dedup, so two buffers can visit one path.
Ownership was tracked as a path-wide `owned: HashSet<path_hash>`, which
made the duplicate case silently corrupting: both dirty buffers queued a
write to autosave/<same hash>, the later write won on disk, and BOTH were
recorded in `written` --- so the loser skipped future sweeps while its
contents were unrecoverable. The path-wide set also let either buffer's
save/kill retire the other's recovery.
A recovery file must stay keyed by path (a later session knows only
paths, never old BufferIds), so two divergent buffers cannot both be
protected under one key. Ownership is now `owner: path_hash -> BufferId`:
- the first modified buffer to reach a free slot claims it, including
within a single pass (the write loop updates `owner`, so the gather
loop tracks slots queued this pass --- otherwise two duplicates both
queue a write);
- any other buffer on that path is counted `conflicted` and reported
("autosave paused for N buffer(s): another buffer is visiting the same
file"), never silently mis-protected. It records no `written` entry, so
it re-attempts each sweep instead of believing itself saved;
- `discard_buffer` (save/kill) retires ONLY slots this buffer owns, which
now enforces both invariants at once: an unowned slot is unclaimed
crash data (Q#AS12), and a slot owned by another buffer is that
buffer's recovery;
- saving or killing the owner releases the slot; the duplicate claims it
on the next sweep;
- `recover-file` adopting into a buffer makes that buffer the owner --- the
file's contents are now its contents, and the previous owner truthfully
becomes conflicted.
sweep() now returns (written, blocked, conflicted). Its gather phase is
extracted into `gather()` (clippy too-many-lines).
This is honest rather than clever: pmacs cannot protect two divergent
buffers over one file, and now says so instead of pretending.
Tests (autosave_acceptance now 27):
duplicate_buffers_on_one_path_conflict_instead_of_corrupting (owner's
copy on disk; the dup never wins the slot by editing),
a_duplicate_buffers_save_does_not_retire_the_owners_recovery,

Addresses the PR #100 review round 2. Q#AS12's ownership rule guarded the
sweep but not the RELEASE paths, so three doors were still open.
The rule is now total: exactly two things may release an unclaimed
recovery file --- recover-file (which adopts it) and discard-recovery
(explicit user intent). Not a sweep, not a save, not a kill.
- HIGH: buffer.after-save called _discard_buffer unconditionally, which
removed the live buffer's current-path key without checking ownership.
Repro: session 1 autosaves and crashes; session 2 opens the file, does
not recover, then saves --- the crash artifact was deleted. Same door
was open on kill. discard_buffer now removes ONLY keys this session
owns. The unclaimed copy survives (reported Stale, so never
auto-offered, but still recoverable/discardable). The on-disk file holds
the new work; the crash copy holds work never written anywhere, so
deleting it was the same data loss by a different door.
- MEDIUM/LOW: _adopt only recorded the path in `owned`, not an
association with the buffer. A removal callback fires after the buffer
has left the registry, so discard_buffer had no path to read and no
`written` entry to fall back on --- recover-then-kill leaked the copy
and it was offered again. adopt now takes the BUFFER and records a
`written` entry at the revision whose contents the file holds. That is
correct twice over: the skip cache declines to rewrite an identical
copy, and a kill can find and retire it.
- LOW: _discard(path) removed the file and unowned the hash but left
matching `written` entries, so a still-dirty buffer hit the unchanged
(path_hash, revision) fast path and went unprotected until its next
edit. discard_path now clears those entries; the next sweep re-protects
immediately.

Addresses the PR #100 review.
- HIGH data loss: sweep could overwrite an existing crash recovery before
the user ran recover-file. Reopen a file after a crash, edit it, and the
next autosave wrote the current buffer over the recovery key --- losing
exactly what autosave exists to protect. New ownership rule (Q#AS12): a
per-session `owned` set records which path hashes THIS session wrote or
adopted. A recovery file at a key we do not own is unclaimed crash data;
the sweep refuses to write that buffer, counts it `blocked`, and says so
("autosave paused for N file(s) with unclaimed recovery"). recover-file
ADOPTS the copy once its contents are in the buffer; discard-recovery
removes it. Either resumes normal autosave. sweep() now returns
(written, blocked).
- MEDIUM cleanup missed paths autosave can write. Kill/save cleanup now
goes through `discard_buffer(BufferId)`, which removes BOTH the buffer's
current-path key and the key its last sweep actually wrote (they differ
after a rename --- an LSP WorkspaceEdit changes the path while the
BufferId stays; a path-captured callback deleted the wrong key). And a
sweep-time GC deletes the recovery of any buffer that left the registry,
which is the backstop for argv `[new file]` buffers: they fire no
after-load, so no removal callback is ever registered for them.
- LOW/MEDIUM recover-file pinned only on the active path. Two buffers can
visit one path (pmacs.buffer.from_file does not dedup), so focus drift
could recover into the wrong buffer. It now captures and compares the
origin buffer handle as well as the path.
- LOW write_private left a pre-existing lax autosave/ directory alone. The
birth-mode only applies to dirs that call creates, so a 0755 autosave/
from an older run still leaked recovery-file names, sizes, and mtimes
despite 0600 contents. It is now tightened to 0700 --- but never `base`
itself, which is shared with history/recentf/desktop and may predate us.
New `state::exists` (an existence check, no read) backs the ownership
gate.

Addresses the PR #99 review:
- HIGH daemon local-only was not reliable: run_daemon sets DaemonMode
only after EditorState::new() has run init.lua, so desktop_mode(true)
in init saw is_daemon()==false and the raw bindings were ungated. Now
save_session/restore_session early-return in Rust when the DaemonMode
marker is present — set right after the daemon's new(), so it holds for
every save/restore that can run after startup (before-quit hook, manual
commands, direct binding calls).
- MEDIUM desktop_mode(false) could not unarm startup restore: arm_restore
is now a boolean (arm_restore(on)) that sets/removes the marker, and
desktop_mode(on) calls arm_restore(on). enable-then-disable no longer
restores.
- MEDIUM/LOW same-file multi-pane missed per-window overlays: restore now
fires buffer.after-load once PER LEAF (per window), not once per buffer.
Syntax attaches its overlay to the active window, so each pane gets its
own; LSP attach_buffer is idempotent, so the same file in two panes
attaches LSP once but syntax to both.
- MEDIUM hidden restored buffers: documented as registry-only in v1 (they
are live/openable/in recentf, but do not fire after-load, so they
attach syntax on first visit via after-switch and LSP when next shown).
Full initial attach for hidden buffers is deferred. Noted in the
framing + a code comment.
- LOW trailing whitespace in docs/desktop-save-framing.md.

Review High (merge blocker): query-replace searched the origin buffer's
bytes but applied edits and moved the cursor through apply_active_edit /
search_place_cursor, which target whatever is ACTIVE. Focus can drift
mid-session — a click into another split, a key from another frontend,
both changing the active buffer outside the shadow — so a match found in
the origin buffer could be applied to an unrelated one. Buffer
corruption.
Fix: query_replace_on_origin() verifies the active buffer still equals
the session's origin buffer before every edit; on mismatch it ABORTS
without editing (clears the highlight, drops the session, status
'query-replace aborted: active buffer changed'), so an origin match can
never land in a foreign buffer. Guards replace/skip/all/replace-and-quit.
The dispatcher's after-edit revision compare now targets the ORIGIN
buffer (query_replace_origin_buffer + buffer_revision) not the active
one, so a drift-abort — which edits nothing — never spuriously fires
the hook. The forward-search clamp uses the origin bytes' length, not
active_buffer_len.
Also (review Low/med): query_replace_active() added to the
completion-popup modal-close guard, so a popup opened via the direct
Lua start (ed.query_replace_start) can't linger rendered-but-unreachable
while QR swallows keys.
Tests: core drift-abort (both buffers untouched) + end-to-end
focus-drift regression; ! fires after-edit exactly once for the batch;
RET/Esc/C-g quit paths (keep replacements); DEL skips. Acceptance
header corrected to match actual coverage.

Three PR #96 review findings (documentation accuracy):
- Q#P7 coordinates section claimed panels inherit a byte==UTF-16 wire
assumption with position-encoding hardening deferred. False as-built:
the transport layer negotiates general.positionEncoding and converts
every Position at the request/response boundary (PositionEncoding +
char_to_byte/byte_to_char, src/lsp.rs), so location rows reach Lua as
byte offsets. Reworded to record what landed; the true residual is
the codepoint-vs-byte cursor walk in move_active_cursor_to (shared
with go_to_definition, not introduced by panels).
- Intro described pre-arc behavior in present tense (references throw
rows away, code actions apply acts[1] blind, ...). Marked as the
pre-arc baseline with a status banner + inline as-built pointers.
- Drifted hard-coded line refs (editor_core.rs:2052-2071,
lsp.lua:658-662, lsp.lua:1187-1213) replaced with symbol names.
Also fixed the move_active_cursor_to comment in lsp.lua itself — it
was the same 'v0.2 hardening' false trail the doc's stale ref pointed
at, now naming the real residual (codepoint-walk, not wire encoding).

Q#P1-P7: panels are buffers (a shared listview runtime module
generalizing the *buffer-list* idiom — zero protocol change, both
frontends render them for free); switch-in-place presentation with q
restore (the GPU cannot show splits); read-only via intercept with its
limits recorded; the Q#P6 round-trip buffer seam so semantic frontends
never optimistic-apply into panels (RET visits instead of inserting a
newline); references list, outline, minibuffer code-action picker,
hover-doc panel; byte==UTF-16 caveat inherited, not multiplied.

Five findings from the manual validation pass, all in-branch:
1. LSP-only words never queried the server: the auto-open path fired
request_completion only when the sync providers already produced
rows. An empty sweep now leaves a pending session and the request
always fires; isIncomplete responses re-request on further typing.
Corollary: attachment_for_request now flushes-if-attached but NEVER
attaches -- the first cut wrapped attached_for_active, which spawns
servers on demand, i.e. per-keystroke spawn attempts in unattached
buffers (wedged the parallel m4 suite; serial ran 3x slower).
Attachment stays buffer-open policy.
2. Cross-buffer LSP leak: the built-in provider's no-uri fallback was
the legacy global store drain, so scratch/unattached buffers could
show another file's cached completions. Strict now: no uri, no rows.
3. Pending prefixes own the keyboard: Action::Pending (C-x ...)
dismisses the popup and the popup shadow is guarded on an empty
dispatcher prefix, so the sequence's continuation and its C-g abort
reach the dispatcher instead of the popup.
4. Window-scoped sessions: CompletionPopupState.window_id (stamped by
completion_popup_open; Lua never sees it). Only the owning window's
overlay paints -- same-buffer splits each carry a persistent
overlay -- and a focus change invalidates the session.
5. Flaky worker test: the /proc thread-count probe and the idempotence
check both build EditorStates and could run concurrently, polluting
the baseline; merged into one test (non-Linux keeps a portable
idempotence variant).
Regression tests for 1-4; framing doc gains the as-built notes.

Fix the control plane for the line-number gutter: M-x
window.toggle-line-numbers now works from EITHER frontend, each affecting
its own window.
Root cause (scores framing bet Q#UX1 false): rendering a gutter is
frontend-local, but the TOGGLE is a daemon command, so the mode has to
reach the GUI over the wire. My earlier GPU control (a --line-numbers flag)
left M-x-in-the-GUI a no-op and the two frontends' settings disconnected.
- Protocol: new additive `InstanceMessage::LineNumbers { buffer_id,
enabled }`; PROTOCOL_VERSION 12 → 13, SUPPORTED grows to [6..13].
Daemon-gated < 13 (a v12 peer keeps its gutter off), like every prior
additive bump — no encoding break.
- Producer: SemanticRenderState::line_numbers_msg reads the frontend's
active window mode (via active_window_for(frontend_id)) and emits on
change; cached-compare suppression seeded to the frontend's `off`
default, so a plain window adds zero traffic and existing frames are
unchanged.
- Daemon: gate LineNumbers >= 13 in the write loop.
- TUI: drops LineNumbers silently (reads its window directly).
- GPU: consumes LineNumbers → drives local `line_numbers`; the
--line-numbers flag retired.
Now the daemon Window.line_numbers is the single source of truth; both
frontends render locally from it.
Tests: line_numbers_msg emit-on-toggle/suppress-when-unchanged; protocol
version pins updated to 13. Validated: fmt + clippy --all-targets clean
both flavors; 1440 lib + 12 protocol + 53 pmacs-gpu tests pass.

Review follow-up on the F-016 split. install_diag / install_project_index
/ install_mcp were `pub fn` reachable at crate::lua_bindings::install_* be-
fore the split, but moving them into private child modules dropped those
paths without a re-export — shrinking the public API, which the split is
supposed to preserve. (They take crate-internal handle types so no external
caller can invoke them, and none does, so nothing actually broke — but the
paths should still resolve.)
Re-export all three alongside the factories/handles already re-exported,
restoring the paths for the two already-merged tranches (diag, index) too.
Deliberately narrowing these to pub(crate) is left as a separate change.

Third tranche of the F-016 split. Extract the pmacs.mcp surface (MCP client
bindings) from src/lua_bindings/mod.rs into src/lua_bindings/mcp.rs,
verbatim.
Corrected model (see framing): a helper-hoist is NOT a prerequisite for
most domains. The contamination that stopped parse/theme bites only when a
shared helper is *defined inside* the range being extracted. A domain that
merely *uses* a cross-section helper reaches it via `super::`
(parent-private access). So mcp extracts cleanly: all its items are
self-contained, and it reaches the JSON converters (still in the lsp
section) via super::json_to_lua / lua_to_json, and SharedProcessSupervisor
via super::. The JSON-helper hoist is deferred to the tranche that
extracts lsp itself (where they're defined).
mod.rs declares `mod mcp;` and re-exports make_mcp_manager (external caller
editor.rs) and McpServerIdLua — the latter to preserve its public-API path
crate::lua_bindings::McpServerIdLua (moving it into a private module had
dropped it from the crate surface; the split must not shrink the public
API).
Pure code motion, no behavior change. mod.rs: 14603 → 14020 lines.

Second tranche of the F-016 split. Extract the pmacs.index surface (the
project symbol-index bindings) from src/lua_bindings/mod.rs into
src/lua_bindings/index.rs, moved verbatim.
index is the one genuinely clean remaining leaf: its private helpers
(symbol_kind_from_lua, lua_symbol_from_table, search_hit_to_lua) are used
only within its own range, and it has zero shared-core coupling — it
depends only on crate::project_index, mlua, and std, reaching one stranded
helper (lua_to_json, still in the lsp section) via `super::`.
mod.rs declares `mod index;` and re-exports `SharedProjectIndexer` +
`make_project_indexer` via `pub use`, so the crate::lua_bindings::… paths
in editor.rs and completion_framework.rs (and an in-file completion-
framework use) stay valid — no external file changes.
Pure code motion, no behavior change. mod.rs: 14986 → 14603 lines.
While vetting the next leaves I found the recon under-counted the
misplaced shared helpers: parse/theme, window, and minibuffer trail off
into shared style/color, caller_source, and command/menu helpers, so a
dedicated helper-hoist tranche must precede them (framing tranche plan
updated). This tranche stops at index rather than force a contaminated
extraction.

First tranche of the F-016 split of the 15k-line src/lua_bindings.rs.
Deliberately minimal — it validates the mechanics before bulk moves.
- Convert src/lua_bindings.rs → src/lua_bindings/mod.rs (the
`pub mod lua_bindings;` in lib.rs resolves to mod.rs unchanged).
- Extract the pmacs.diag surface (diagnostic_to_lua + install_diag) into
src/lua_bindings/diag.rs, moved verbatim. mod.rs declares `mod diag;`
and its one internal call site is now `diag::install_diag(...)`.
Pure code motion: no logic, signature, or behavior change. diag.rs reaches
shared-core items (BufferIdLua, SharedCore) via `super::` — a child module
can see its ancestors' private items, so no visibility widening was
needed; install_diag's only caller is mod.rs itself, so no re-export
either. The Lua-visible pmacs.diag.* API is byte-for-byte unchanged.

`--all-features` can't build pmacs — luajit and lua54 select mlua's
mutually-exclusive Lua backends. Document the model so generic tooling
(CI, cargo hack, distro packaging) doesn't trip over it:
- README §Build: a feature-matrix table (luajit default / lua54 fallback /
orthogonal crdt), the supported build lines, and an explicit "don't use
--all-features".
- src/lib.rs crate docs: a "Lua flavor features" section stating the
exactly-one-flavor rule.
- Cargo.toml [features]: expanded comment on the mutual exclusivity.
CI already iterates the flavors explicitly (never --all-features), so no
CI change was needed.
The audit's suggested crate-local compile_error! for the wrong-flavor case
was investigated and rejected as unreachable: the flavor check lives in
the mlua-sys *build script*, which cargo compiles before the pmacs crate,
so a mis-set flavor (both or neither) fails there first and pmacs's own
compile_error! never evaluates — confirmed empirically for both cases. A
dependent crate can't preempt a dependency's build failure, so the docs
are the honest mitigation and they name mlua-sys as the actual error
surface.

Review follow-up on F-005. The basename-collision check only ran in
ResolverState::into_plan, which covers fresh resolves and UpdateOne — but
UpdatePolicy::Frozen returns Lockfile::to_resolve_plan(...) directly,
building a ResolvePlan without the check. A pre-existing or hand-edited
lockfile containing two distinct packages that share an install basename
(e.g. owner/magit and other/magit) would produce one plan and install both
to <root>/<basename>, silently colliding.
Make find_basename_collision (and its message helper) pub(crate) and apply
it in Lockfile::to_resolve_plan too — up front, before any fetch, so a
colliding lockfile fails fast via a new LockfileError::BasenameCollision
(surfaced through the Frozen path as ResolveError::Lockfile). Both
plan-construction sites now reject; to_resolve_plan is pub and has direct
callers, so guarding the method (not just the resolve_with_policy branch)
covers them all.
New unit test builds a two-entry colliding lockfile and asserts
to_resolve_plan rejects it before touching the fetcher.
Validated: fmt clean; clippy --all-targets clean under both Lua flavors;
1437 lib tests pass (incl. the new frozen-path test).
