Levi Neuwirth dc26c84b7c feat(protocol): v15 CompletionPopup message + producer + daemon gate (Q#C5)
InstanceMessage::CompletionPopup {buffer_id, anchor: Option<u64>,
prefix_len, rows: Vec<CompletionPopupRow{label, kind, detail}>,
selected, total} -- the first byte-anchored popup on the wire: the
frontend maps byte -> glyph rect locally (the caret precedent), so the
instance never learns a pixel. Rows are display-only; accept resolves
daemon-side via dispatch_completion_key, so insert text never ships.
PROTOCOL_VERSION 14 -> 15, SUPPORTED extended; postcard round-trip
(open + closed shapes) and version-pin/ladder tests updated.

Producer: semantic_render::completion_popup_msg, the family pattern
(per-buffer cached-compare, active-buffer only, first-sight-closed
stays silent) with one new rule -- the session is WINDOW-stamped and
this state is per-frontend, so only the frontend whose own window
owns the session sees it open: a popup opened by TUI typing never
renders in an attached GPU and vice versa. Windowed rows share the
TUI overlay's POPUP_MAX_ROWS. Daemon-gated >= 15 (a v14 peer still
completes via the key round-trip, it just gets no GPU dropdown).

GPU consumption follows in this branch.

feat(completion): in-buffer completion popup — Arc 1a phase 1 (core + TUI)
2026-07-07 17:01:47 -04:00
Levi Neuwirth 61a31b3ad4 fix(completion): address TUI-validation findings (LSP query gaps, scoping, prefix keys, window scope)
Five findings from the manual validation pass, all in-branch:

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

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

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

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

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

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

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

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

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

Levi Neuwirth c01cfd1e93 test(completion): popup acceptance suite; fix pmacs.completion table clobber
Seven end-to-end tests through dispatch_key: dabbrev auto-open + TAB
accept, C-n/RET second-candidate accept, Esc dismiss with fall-through
typing (and no same-edit reopen), Home-breaks-anchor validation close,
yank-shaped edits never auto-open (Q#C9), C-M-i below the threshold,
and ctx.uri scoping through the Lua provider surface.

The suite immediately caught a real wiring bug: install_completion
(M4.7, runs at make_lsp_manager time) built pmacs.completion with a
fresh lua.create_table(), clobbering the popup bindings installed at
editor-attach time --- popup_visible was nil at runtime and the driver
hook errored silently into *errors* on every edit. It now merges into
the existing table, the same idiom as install_completion_framework,
so installer order no longer matters.

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

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

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

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

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

Levi Neuwirth 1670233057 fix(gpu): gutter click classification + fit guard; test v14 wire round-trip
Three correctness findings from the sub-arc 3 review:

1. (F1) GPU gutter clicks weren't classified before text hit-testing — the
   hit path just subtracted `text_left()` and called `buffer.hit()`, so a
   click in the gutter band fed glyphon a negative x (undefined) and gave
   future gutter markers no stable seam. Extracted `gutter_aware_rel_x`: a
   click left of the text origin clamps to `0.0` (the line start), mirroring
   the TUI's saturate-to-column-0 affordance. The hit path now branches on
   it — the seam a future marker would hook.

2. (F2) The GPU had no fit guard when the gutter consumed the text width.
   The TUI drops the gutter for a too-narrow window; the GPU always grew
   `text_left()` and `text_bounds_right()` floored against `TEXT_LEFT`, so a
   narrow window or very large file could produce `left >= right` (blank /
   undefined render). `gutter_width_px` now drops the gutter when it would
   leave less than `MIN_TEXT_WIDTH_PX` of text past `TEXT_LEFT`.

3. (F3) The v14 `LineNumbers { mode }` shape had no direct postcard
   round-trip (only the version pin + daemon gate). Added one covering all
   four `LineNumberMode` variants, so a future enum reorder can't silently
   shift the wire.

Tests: `gutter_aware_rel_x` clamps the band (and passes through with the
gutter off); a 60px window drops the gutter while an 800px one keeps it;
all four modes round-trip. fmt + clippy --all-targets clean both flavors +
gpu; 1447 lib + 12 protocol + 57 pmacs-gpu tests pass.

Levi Neuwirth 40ebdd8d7e feat(gpu): relative + hybrid line numbers over protocol v14 (sub-arc 3, GPU half)
Carry the line-number mode to the GPU so it renders relative/hybrid, not
just on/off. The v13 wire carried `LineNumbers { enabled: bool }`
(off/absolute only); v14 carries the full mode.

- Protocol: `LineNumberMode {Off, Absolute, Relative, Hybrid}` moves into
  pmacs-protocol (with `number_for`/`is_on`) so the wire, daemon, and both
  frontends share ONE enum and ONE number rule (Q#UX7); `pmacs` re-exports
  it as `crate:🪟:LineNumberMode`. `LineNumbers.enabled: bool` →
  `mode: LineNumberMode`. PROTOCOL_VERSION 13 → 14, SUPPORTED → [6..14],
  daemon-gated `< 14` (a v13 peer gets no LineNumbers, like the v10
  SearchPrompt bump).
- Producer (`line_numbers_msg`): ships the window's mode (cached-suppress
  on the mode now, seeded to Off).
- GPU: `line_numbers` field becomes the mode; `refresh_gutter_buffer`
  computes each number via `mode.number_for(line, cursor_line)` against the
  GPU's own cursor line (`cursor_line()` off `current_line_starts`). The
  buffer rebuilds every render, so relative numbers track the cursor for
  free. Gutter width unchanged (sized by line count → stable).

Tests: GPU headless render proves relative ≠ absolute with the cursor on
line 2; producer test asserts the mode ships; protocol version pins → 14.
fmt + clippy --all-targets clean both flavors + gpu; 1446 lib + 12 protocol
+ 55 pmacs-gpu tests pass. Needs a GPU eyeball.

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

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

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

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

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

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

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

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

Levi Neuwirth d941bf176b feat(gpu): diagnostic gutter signs riding the line-number gutter (sub-arc 2)
GPU half of sub-arc 2. When the gutter is on, each line carrying a
diagnostic gets a thin severity-colored bar at the gutter's left edge —
the GPU analogue of the TUI's leading-column E/W/I/H sign glyph. No
protocol change: the per-line severity comes from `current_decorations`,
already frontend-side.

- collect_gutter_sign_rects: per visible line (layout_runs), find the
  most-severe diagnostic decoration overlapping that line's byte range and
  push a `GUTTER_SIGN_W`-wide full-line-height quad at `GUTTER_SIGN_X`,
  colored via decoration_kind_to_underline_color. Most-severe wins
  (diagnostic_severity_rank; min rank). Gated on line_numbers, mirroring
  the TUI (signs ride the line-number gutter).
- The bars ride the existing background quad batch
  (decoration_background_vertex_bytes), so no new pipeline.

Headless render test asserts a diagnostic adds ink with the gutter on.
fmt + clippy --all-targets clean; 54 pmacs-gpu tests pass (render tests on
the local adapter). Needs a GPU eyeball before the sub-arc 2 PR.

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

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

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

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

fix(core): scope window close to the active frontend (multi-frontend daemon crash)
2026-07-06 19:17:41 -04:00
Levi Neuwirth 0ed7d7644a fix(core): scope window close to the active frontend (multi-frontend crash)
`close_active` and `close_others` operated on the global `self.windows`
set, which holds *every* attached frontend's windows. With more than one
frontend attached (e.g. a headless `--daemon` plus a pmacs-gpu — two
windows total), closing from one frontend reached across into another's:

- `close_others` did `self.windows.retain(|id| *id == keep)`, deleting the
  OTHER frontend's window. Its `view.active` was then dangling and the next
  per-tick `active_window()` panicked ("active window present in
  core.windows", editor_core.rs:324) — a daemon crash.
- `close_active`'s "only one left" guard checked the global count
  (`self.windows.len() <= 1`), so it also proceeded across frontends and
  could empty a frontend's layout, panicking on the successor pick.

Both now scope to the active frontend's layout: `close_active` gates on
`active_layout().iter_ids().len()`, and `close_others` prunes only the
active layout's own window ids from `self.windows`.

Regression tests: closing from a second frontend must not remove another
frontend's window, and close-active refuses a frontend's last window even
when other frontends have their own. fmt + clippy clean both flavors; 1442
lib tests pass.

Levi Neuwirth 3370ae32ac fix(gpu): resize the gutter buffer so line numbers don't stop at ~10
The GPU window opens at 800x200 and the gutter buffer was sized to that
height once at construction. On resize the code buffer is re-sized but the
gutter buffer wasn't, so `shape_until_scroll` only shaped the ~10 lines
that fit the stale 200px height — line numbers stopped at 10 in a
full-height window (the code + every other buffer scaled fine).

Add `gutter_buffer.set_size(width, height)` to the resize handler,
alongside the code/status buffers. The headless path already sizes it
correctly at construction (its window size is final), so its render test
is unaffected.

Levi Neuwirth 1ea2d5f17f feat(gutter): daemon-owned line-number mode over protocol v13 (unified toggle)
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.

Levi Neuwirth f7583e7994 feat(gpu): line-number gutter (UX arc sub-arc 1, GPU half)
Mirror the TUI line-number gutter in the pmacs-gpu frontend — the GPU half
of sub-arc 1. Frontend-local, no protocol change (Q#UX1); off by default,
enabled with `--line-numbers`.

The gutter is a reserved left strip mirroring the minimap's reserved right
column. All horizontal text geometry hangs off `TEXT_LEFT`; the gutter adds
`gutter_width_px()` to it via `text_left()`, applied at every byte→pixel x
site (main TextArea, caret, washes/squiggles) and subtracted at the one
pixel→byte site (mouse hit-test). The main text clip-left moves off 0.

- gutter_width_px = digits(line_count) * mono_advance + gap (px), advance
  read from the shaped code buffer.
- A dedicated gutter_text_renderer + gutter_buffer draw right-aligned dim
  numbers, reshaped per scroll (refresh_gutter_buffer), same font size +
  line height as the code so rows align one-for-one.
- --line-numbers flag filtered out before the mode parser (position-
  independent), threaded App → State.

Headless render test asserts enabling the gutter changes the frame (ink +
shift). fmt + clippy clean; 53 pmacs-gpu tests pass (render tests on the
local adapter). Needs a human eyeball before the PR.

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

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

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

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

Levi Neuwirth 296cf34ae9 refactor(lua): re-export install_* wiring fns to preserve the public API
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.

Levi Neuwirth e8e56bdbf1 refactor(lua): extract pmacs.mcp into its own module (F-016, tranche 2)
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.

Validated: fmt clean; clippy --lib clean under both Lua flavors; full lib
suite 1437 passed / 0 failed under both luajit and lua54.

Levi Neuwirth df35e03ecf refactor(lua): extract pmacs.index into its own module (F-016, tranche 1)
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.

Levi Neuwirth d002b7da71 refactor(lua): split lua_bindings.rs into a module dir; extract pmacs.diag (F-016, tranche 0)
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.

mod.rs: 15202 → 14986 lines. Framing + tranche plan:
docs/lua-bindings-split-framing.md.

Validated: fmt clean; clippy --lib clean under both Lua flavors; full lib
suite 1437 passed / 0 failed under luajit AND lua54 (the tests drive
pmacs.diag.* through the Lua VM — same outcomes, code relocated).

Levi Neuwirth 3b630bfee4 docs(features): document the Lua feature matrix; drop unreachable compile_error idea (F-002)
`--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.

Validated: fmt clean; clippy clean under both Lua flavors; both flavors
build.

Levi Neuwirth 8472c4d87b fix(packages): F-005 must also guard the frozen/lockfile plan path
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).

Levi Neuwirth 1694908e9c fix(packages): basename-collision reject, SHA-256 cache key, timeout thread join, commit→revision, dead-code (F-005/F-009–F-012)
Package-manager hardening sweep from the repo audit — one Medium + four
Lows, all in src/packages/ (F-011 also renames across lua_bindings + tests).

F-005 (Medium) — install dirs are named by package basename and require
routes by basename, so two distinct packages `owner/magit` and
`other/magit` collapse to one dir with most-recent-install silently
winning. Reject a resolve plan that contains distinct names sharing a
basename: new ResolveError::BasenameCollision + find_basename_collision()
in into_plan (the one place holding every name at once). The loader's
*intended* cross-scope override (project- vs user-scope, most-recent-first)
is untouched — its test still passes. Namespace-preserving layout and
cross-resolve install-time detection are named-deferred.

F-009 (Low) — the fetch bare-mirror cache dir was keyed by 64-bit FNV-1a
of the (attacker-adjacent) repo URL — trivially collidable. Swap to
SHA-256 (sha2, already a dep for lockfile hashing). normalize_url still
folds equivalent URLs to one entry; only the digest changes (re-clones
once, it's a cache).

F-010 (Low) — on a git subprocess timeout, run_with_timeout returned
before joining the stdout/stderr drain threads (joined only on the normal
path), leaving detached readers. Restructure to break the wait loop with a
Result, reap the child on every path, and join both threads at one point
before propagating.

F-011 (Low) — ResolvedPackage.commit was documented "Full 40-character
commit hash" but commit_for_tag() puts a tag string there (the resolver
works against commit-ishes by design, deferring SHA resolution to the
installer/lockfile). Rename the field to `revision` + honest doc.
Compiler-driven rename hit exactly the ResolvedPackage sites; the
Lua-visible "commit" record key is unchanged.

F-012 (Low) — the topo sort built an indegree map, argued in comments it
was backwards, and rebuilt it. Delete the dead first block + the
meandering narration.

Levi Neuwirth 45b02d1597 fix(gpu): F-008 fail-fast must actually tear down the session, not just flag it
Review follow-up on the F-008 bounded outbox. Closing the outbox on a
lossless overflow set a `closed` flag but did not disconnect: the reader
stayed blocked on its still-open socket clone, so no `Disconnected` fired,
the daemon was never signaled, and the optimistic CRDT edit whose
`send_crdt_op` failed was applied locally, logged, and forgotten. That is
silent divergence — the GPU keeps showing text the daemon never received,
the exact stalled-daemon case F-008 exists to handle.

Keep a `shutdown_handle` socket clone and `shutdown(Both)` whenever the
outbox closes — the overflow path in `send_event`, and the writer's own
write-failure path. Clones share the socket's file description, so the
shutdown wakes the reader (blocked in `read_message`) with EOF: it fires
the existing `Disconnected` flow, which renders `(daemon disconnected)`,
and the daemon sees the half-close. The fail-fast is now a real teardown
→ the user gets a visible disconnect (and a fresh snapshot on re-attach)
instead of a silently diverged buffer.

New socketpair test asserts a send against a closed outbox drives the peer
to EOF. Auto-reconnect/resync remains deferred (named in the framing).

Validated: fmt clean; clippy -p pmacs-gpu --all-targets clean; 52
pmacs-gpu tests pass (incl. the new shutdown test + both headless renders

Levi Neuwirth be6943c49d fix(gpu): attach robustness — clear non-CRDT error, bounded queue, clamped dropdown (F-003/F-008/F-007)
GPU attach-path robustness batch from the repo audit. All three live in
pmacs-gpu; no protocol or daemon change.

F-003 — a daemon built without `--features crdt` advertises
`crdt_replica`/`semantic_render` as false in its `Hello`; negotiation then
"succeeds" but no BufferSnapshot ever arrives and the window hangs on
`(connecting...)`. The daemon already tells us its capabilities in Hello,
so check them client-side right after the handshake and fail with an
actionable in-window line ("daemon lacks CRDT support — restart it built
with --features crdt") instead of hanging. New CapabilityMismatch error +
missing_capabilities() + window_status(). No AttachResponse/daemon change.

F-008 — the outbound FrontendEvent queue was an unbounded mpsc, so a
stalled daemon grew memory without bound and replayed stale
viewport/pointer traffic on recovery. Replace it with a bounded,
coalescing Outbox (Mutex + Condvar): a Viewport or Pointer{Drag} whose
kind matches the queue tail replaces it (collapsing scroll/drag floods to
O(1) without reordering across a click or key), everything else is
appended lossless, and a lossless append past OUTBOX_MAX fails fast
(closes the outbox → clean disconnect/resync) rather than silently drop a
CrdtOp and desync the optimistic replica.

F-007 — the completion dropdown grew upward by n*row_height with no clamp,
so a short window rendered rows above y=0 with the selection off-screen.
Add mb_dropdown_window(n, selected, band_top) → (first, count): clamp the
count to rows that fit (hide when not even one fits, so top_y is never
negative) and scroll to keep the selection visible. glyphon's existing
TextBounds clip the scrolled-out rows; the buffer is still shaped once, so
no per-resize re-shape. The whole-fits path is (0, n) — byte-identical to
before.

Levi Neuwirth 623bd884af fix(gpu): F-004 AltGr strip → Ctrl+Alt only; run pmacs-protocol tests in CI
Two follow-ups on this session's audit work, both on freshly-merged code.

F-004 hardening (regression fix). The AltGr text-input strip
(`is_layout_text`) gated on *any* command modifier, so it fired on
Alt-alone. On macOS the Option key is reported as Alt and emits printable
text for most letters (Option+x → "≈"), so every GUI Meta binding (M-x,
M-f, M-b, …) was stripped to a self-insert. Tighten the gate to the true
AltGr signature — both Ctrl and Alt (the LCtrl+RAlt the OS synthesizes on
Windows) — so Alt-alone forwards as a Meta chord again while Windows AltGr
still inserts. Strict narrowing of when we strip: no-op on Linux/Windows,
unblocks macOS Option-as-Meta. Test flips the Alt-alone € assertion and
adds the macOS Option+x case.

CI coverage (F-001 residue). `workspace_default_members` is only the root
`pmacs` package, so `cargo test` skipped pmacs-protocol — the shared wire
format the daemon, TUI, and GPU all depend on. Add
`cargo test -p pmacs-protocol --all-targets` to the test job (its ~12
encode/decode + transport-framing tests). All three first-party crates now
run in CI (root pmacs, pmacs-gpu via the render job, now pmacs-protocol).

Validated: fmt clean; clippy -p pmacs-gpu --all-targets clean; pmacs-gpu
tests 42 pass (render tests on the local adapter, PMACS_REQUIRE_GPU=1);
pmacs-protocol 12 pass.

The first run showed lavapipe installed and visible to vulkaninfo
(DRIVER_ID_MESA_LLVMPIPE), but the render tests still found no wgpu
adapter and — correctly — hard-failed under PMACS_REQUIRE_GPU. Cause:
VK_ICD_FILENAMES pinned an ICD path that doesn't match the runner, which
overrides the loader's default discovery and hides every ICD. Drop it and
rely on default discovery (which vulkaninfo uses); also `ls` the icd.d
dir for future debugging.

Levi Neuwirth a5f1372b3e pmacs GPU: headless render harness + lavapipe CI gate (F-014)
Audit F-014. pmacs-gpu had 40 tests but none exercised the wgpu
composition path — layout/render regressions passed silently, a human
eyeball the only gate. This adds the first tests that actually render a
frame, headless, and read the pixels back.

Enabling refactor (least-invasive; not the Renderer-sub-struct split):
- `State.window`/`.surface` become `Option`; a shared `assemble(...)`
  builds the window-agnostic half, called by both the windowed `new`
  and a `#[cfg(test)] new_headless(w, h, text)` (compatible_surface:
  None, returns None when no adapter). `request_redraw` is now an
  Option-guarded helper across its 15 sites; `resize` guards
  `surface.configure`.
- `render()` splits into a surface-acquire wrapper + window-agnostic
  `render_to_view(&TextureView)`; `#[cfg(test)] render_offscreen()`
  renders through the same path into a RENDER_ATTACHMENT|COPY_SRC
  texture and reads it back (256-byte row alignment).

Two smoke tests through the real composition path: a full frame is
non-uniform (something composited); setting text changes the frame vs an
empty buffer. They skip when no adapter is present, except under
`PMACS_REQUIRE_GPU` (CI) where a missing adapter is a hard failure.

CI: a "GPU Render (headless)" job installs mesa-vulkan-drivers
(lavapipe) and runs `cargo test -p pmacs-gpu` — also the first time
pmacs-gpu's tests run in CI at all (the workspace test job covers only
the root package).
