Three of the five review findings land here; the other two are recorded
as named deferrals in the framing on the dired branch.
Finding 1: the command comment cited "acc4", a name from a draft scheme
that no test carries. It now names the real test, and the comment splits
the shadowing consequence into the two cases that actually exist -- a new
bare name that matches an entry (shadowed) versus one that matches
nothing (creates normally) -- each pointing at its test.
Finding 2: the everyday new-file flow had no test. Typing a bare name
that is not a subsequence of any entry is the path users hit first, and
the only route combining free text with a relative join; every existing
new-file test used a name containing a separator.
find_file_bare_new_name_creates_in_the_root covers it, asserting the
parent is the prompt's root so the join itself is pinned.
Finding 3: the failure arm was never exercised, and as the review noted,
deleting the pcall would have passed the whole suite. Accepting a
directory candidate reaches display_file, whose load fails because
File::open on a directory succeeds and the read returns EISDIR;
find_file_accepting_a_directory_reports_instead_of_raising pins that this
surfaces as the command's status message, leaves the active buffer alone,
and closes the prompt. Verified by manual revert: with the pcall replaced
by a direct call, that test and only that test fails. scripts/bite could
not isolate it, since the guard and its test have no separating commit.
Finding 4 is documented at the command rather than left implicit:
accepting on empty input opens the first-sorted candidate, because
fuzzy_score returns Some(0) for an empty needle and filter_and_sort
breaks the tie lexicographically, so dotfiles lead and a directory can
lead. M-x and switch-buffer share the mechanism, so it is inherited
rather than introduced, and it is listed in the framing beside the
accept-semantics change that would close it.
Dired arc Stage 0 (docs/dired-framing.md section 10, Q#DR11). Until now
pmacs had no discoverable way to open a file by path: no find-file
command and no C-x C-f binding, so a file entered a session only from
the CLI, an LSP jump, a project-search visit, or C-x C-r, whose prompt
does pass free text through but completes only over the recent list.
The command prompts with completion rooted at the active buffer's
directory, or the process cwd when the buffer has no backing path, and
opens the result through pmacs.window.display_file. A path that does not
exist yet creates a buffer bound to it with the "[new file]" status,
which is Emacs parity and comes from resolve_target_buffer rather than
anything added here. Nothing is written to disk until the user saves.
Two substrate facts shape the design and are documented at the command
rather than left to be rediscovered.
Completion is flat: the files source lists one directory and yields bare
basenames, and a custom function source could not do better, because
sources are called with no arguments and run synchronously outside any
coroutine, so a callback can neither see the input to re-root on nor
await a directory listing. Hierarchical completion is a named Rust
change in the framing.
A selected candidate shadows typed text: recompute_candidates selects
index 0 whenever the candidate list is non-empty, and
resolve_accepted_value returns the candidate over the typed contents. So
typed text reaches the accept handler exactly when the input filters
every candidate away, which for basename candidates under a subsequence
filter means when it contains a separator. That makes the deeper-path
case work verbatim and leaves one hole: a new bare name that is a
subsequence of an existing entry opens the existing file. The acceptance
pins that as a decision rather than an accident; closing it needs a Rust
change to accept semantics that Stage 0 deliberately does not make.
A leading tilde is expanded before the path reaches the core, because
get_or_load_buffer normalizes the path it stores but loads from the raw
one -- so an unexpanded tilde path deduplicates against an already-open
buffer yet fails to load a file that is not open yet.
The prompt field starts empty and names its root in the prompt string
instead: any prefill would contain a separator and silently disable
completion.
Acceptance is dispatch-driven throughout -- a real C-x C-f, real typing,
a real RET -- so a dead binding cannot pass vacuously and the Lua
lifecycle accept(), which bypasses the path interactive input takes, is
not used.
Review finding: acc12's server-list assertion could not fail for the
regression class it was written to catch. The shared `editor()` helper
runs `pmacs.lsp.config = {}` before any buffer opens, so
`#pmacs.lsp.list() == 0` holds for every language regardless of what
Stage 1 ships -- a Stage-3 front-run that added
`pmacs.lsp.config.lean4` in a builtin runtime file would have slipped
straight past it. The same vacuous-assertion shape as #155 R2.
acc12 now asserts the actual claim against a PRISTINE `EditorState`,
before any config wipe: no builtin runtime file defines
`pmacs.lsp.config.lean4`. A non-vacuity check pins that the same lookup
finds `pmacs.lsp.config.rust`, so this cannot pass merely because the
table is empty or absent.
Bite-verified: adding `pmacs.lsp.config.lean4 = ... { command = "lake",
args = { "serve" } }` to `builtin/runtime/lsp.lua` fails the test; the
stub was reverted.
The process-list half is kept and its comment now says why it survives
the wipe: a direct probe spawn from a future `lean.lua` shows up there
whatever `pmacs.lsp.config` contains.
Also fixes a stale column in a `highlight.rs` comment -- the Lua table
brace in `local t = {}` is at col 10, which is what the code already
used.
Gates rerun: fmt and strict workspace clippy clean; 1,826 default +

Completes Arc 8 Stage 1: the Lua-side tables that turn a recognized
grammar into a usable mode, plus the acceptance suite for all twelve
framing criteria.
comment.lua -- `lean4 = "--"` (Q#LN5). Line comments only; Lean's block
comment `/- -/` and docstring `/-- -/` belong to the comment arc's own
named deferral and this lane does not front-run it.
pair.lua -- `⟨⟩`, `⦃⦄`, `⟮⟯` alongside the ASCII brackets (Q#LN6). The
anonymous constructor is among the most-typed constructs in Lean;
omitting it would make the pair set feel broken. The other two ride along
because the Stage 4 input method can produce them, and a bracket the pair
set does not understand is worse than one it does. All three sit outside
the nine built-in pair chars, so per Q#AP1 their undo is
cross-peer-degraded -- the documented, pre-existing limitation of
user-extended pairs. No `''`: Lean uses the prime as an identifier suffix
(`h'`, `foo'`), the same reason Rust excludes it.
syntax.lua -- the `lean` -> `lean4` modeline alias (Q#LN2), so an Emacs
`-*- mode: lean -*-` or a Vim `ft=lean` line is not stranded by the entry
being named `lean4`.
syntax.rs -- the `lean` -> `lean4` injection alias (Q#LN17), so both
```lean and ```lean4 fences highlight. The Lean 3 spelling is mapped
forward deliberately: a ```lean fence is overwhelmingly Lean 4 in
practice.
highlight.rs -- `warning` moves from bold red to bold BRIGHT red. Writing
the test found the collision: `number` is plain `fg(1)`, so `sorry` and
the literal `42` beside it were the same colour, differing only in the
bold flag. `sorry` means "admitted, not proved" and is the one token in a
proof file a reader must never skim past, so it now gets the loudest
entry in the table and the test asserts the full style rather than the
colour.
Twelve criteria, seventeen tests. Notes on the ones that could have been
vacuous:
* acc4 uses a `.txt` fixture, not `.lean` -- on a `.lean` path the
extension alone yields `lean4` and the assertion would pass with the
alias table empty. acc4b removes the alias and pins that the raw name
survives, so acc4 cannot silently stop testing anything.
* acc11 goes through the real `_parse_now` injection path and asserts a
`lean4` CHILD LAYER appears. `pmacs.parse.injection_aliases` is a
documented write-only proxy, so an alias-table read would have proven
nothing about the parser; acc11b pins that a misspelled fence still
resolves to nothing.
* acc12 asserts through the process supervisor and the server list that
opening a Lean buffer spawns nothing. This is not decorative: the
machine this arc was scouted on has elan installed with no default
toolchain, where `lake --version` itself fails, and Stage 1 must be
unaffected by that.
Gates: fmt and strict workspace clippy clean; 1,826 default + 2,003 CRDT
library tests; lean4 Stage 1 9, comment toggle 14, auto-pair 45,
injection 4; M4 121; required GPU 152; isolated-config workspace sweep
3,150 across 90 suites; `git diff --check` clean.

PR #155 review round 2, self-review of the round-2 commit.
The round-2 change labelled "minor" — resolving both arms of
pmacs.window.buffer() through the acting frontend for uniformity — made
the NO-ARGUMENT arm fallible. `acting_frontend` follows the interactive
origin, which can name a frontend that has no registered view: a bare
`dispatch_key` from an unattached peer does exactly that. `selected_window`
then raises "acting frontend has no layout" instead of answering.
Nothing surfaced that error, because the runtime callers do not pcall it.
killring, syntax, autosave, pair, indent and comment all read
pmacs.window.buffer() on ordinary edits, so the raise silently dropped
the operation: kill_ring_acceptance went 30/30 to 25/5, with
frontend_detached_drops_per_frontend_state reporting only "B has kill
state". main is 30/30, and reverting this one file restored it.
The no-arg arm is back on ambient active_buffer_id() and now documents
why that is deliberate rather than an oversight: dispatch sets
active_frontend to the acting frontend before running a command, so the
two agree on every real path, while only the ambient resolver has the
fallback that makes it total. The explicit-window arm keeps its Q#BP11
layout validation, which is what the arc actually needed.
acc19c pins it through the real path — a buffer.after-edit subscriber
reading pmacs.window.buffer() during a viewless peer's dispatch_key —
rather than by calling the binding directly. Bite-verified:
scripts/bite bbe4152 src/lua_bindings/mod.rs --test
bottom_panel_stage1_acceptance -- acc19c goes red with the exact
"acting frontend has no layout" traceback.
The ledger also records two gating facts found on the way: the workspace
sweep must run with an isolated XDG_CONFIG_HOME, because the real user
init.lua installs a local package and the losing race leaks a status
message into painted-frame comparisons; and a latent pre-existing main
bug in the buffer CRDT undo path, which is not this branch's and whose
proptest seed is deliberately not committed here.

The round-2 peer press landed in the peer's CONTENT area, so it never
reached `arm_window_drag` — the exact path Finding 5 names — and the
case bit nothing. It now presses the peer's own mode-line row, where a
single global drag slot is overwritten (and, since that lone window owns
no boundary, cleared outright).

PR #155 review round 2.
Finding 1 (must fix): Q#BP7 item 1 — "growth reaching the live tail
re-arms follow (top -> None), only when no selection is active" — was
never implemented. `at_bottom` is the instantaneous geometric readout
`scroll_offset == 0`, which a still-anchored view satisfies whenever it
happens to be tall enough to reach the tail, so the round-1 assertion
could not see the gap: the next rows the child printed pushed the
anchored view back into history.
`rearm_follow_on_growth` now clears `top` when a viewport-size
declaration makes the view cover the tail and no selection is frozen,
and every size-declaring path (`snapshot_for_view`, `record_view_size`,
`view_status_for_size`) routes through one `declare_view_size` helper so
grid and semantic declarations cannot disagree. `scroll_view` and
`begin_selection` deliberately stay out: they write `top` themselves,
and `scroll_view` already owns the scroll-driven arm.
New acc32b is the pin the review asked for: scroll into history, grow
past the tail, then release a SECOND burst of child output through a
filesystem gate and assert the view moved with it.
Finding 2: the PTY fixtures emitted LF-only output, which staircases
rightward until every row clips to blanks past the viewport width — so
the round-1 anchor assertions compared "" with "" and could not fail.
Both fixtures now emit CRLF, and each anchor comparison is guarded by
`assert!(!top_before.is_empty())`.
Finding 3: acc33's contrast case asserted nothing, and the behavior it
claimed was false as coded. With the re-arm in place it is true and now
asserted: clearing the selection at the same geometry re-arms follow and
leaves the frozen anchor.
Finding 4: `start_run` gated the panel branch on `display == "panel" or
already_in_panel(..)`, so an explicit `display = "current"` lost to the
inference — and that value is the documented user-facing opt-out from
the Stage 3 default flip. Now gated on OMISSION. acc19b gains the
explicit-"current" case.
Finding 5: `window_drag` is a `HashMap<FrontendId, WindowDragState>`, so
a peer's mode-line press can no longer steal or clear another
frontend's in-flight gesture, and concurrent drags are legal. Cleared on
detach. acc30c gains the mode-line-press case.
Minor: `pmacs.window.buffer()` resolves both arms through the acting
frontend using the shared `lookup_window` / `selected_window` validators
rather than re-implementing them beside an ambient `active_buffer_id()`.

`TerminalViewStatus.scroll_offset` is the retained rows between the
VIEWPORT and the live tail, so it necessarily tracks viewport height: an
assertion that it survives a panel height change unchanged is either
vacuous or wrong, and it went red once under a loaded sweep for exactly
that reason. Q#BP7's invariant is that the ANCHOR is frozen, so acc32
and acc33 now compare the first visible row's text across the change,
and additionally pin the follow behavior that distinguishes them: a
shrink never re-arms follow, growth reaching the tail does, and growth
with a frozen selection does not.
Both also wait for the child's last line before sampling, so neither
races further output.
Also records the round in docs/active-work.md.

PR #155 review round 1.
Finding 1 (must fix): `try_split_active` had no production caller —
`pmacs.window.split_horizontal` / `split_vertical`, and therefore
`C-x 2` / `C-x 3`, still went through plain `split_active`. Splitting a
focused panel made the root wrapper's final child a split rather than
`Leaf(side)`, which both `Layout::compute`'s fixed pass and
`document_subtree` key on: the panel band reverted to 1:1 weight
division and an ordinary window ended up living inside it. Both bindings
now route through the guard, and acc26 asserts through the real Lua
path — a direct core call passes with the guard unwired, which is how it
survived the first round.
Finding 2: the armed-drag early return now checks the arming frontend,
so one frontend's in-flight gesture cannot cancel or swallow another's
mouse events. New acc30c.
Finding 3: `paint_mode_line_graphemes`'s doc block was left heading
`paint_divider_segment`; moved back.
Finding 4: a recompile carries no `display`, so it took the raw switch
and duplicated a panel-placed `*compilation*` into the document window.
`start_run` now detects that the buffer already owns the panel slot.
`pmacs.window.buffer` gained an optional window argument so an adopter
can ask without selecting the panel first. New acc19b.
Stage-2 hazard pins the review asked for, both in `src/daemon.rs`:
a fresh attach while LOCAL is focused in a panel inherits LOCAL's
document buffer, and an initial-target bootstrap whose `after-load`
hook creates and selects a panel still reasserts into a document window.
Minor: dropped listview's dead `p.side`; documented `focus_window`'s
caller-validates contract; `jump_back` restores through `focus_window`
so the "every focus change" contract holds; `params` / `resize` default
to the acting frontend's selected window rather than the ambient one;
widened the flexible-division math to u64 intermediates.

Both earlier attempts in this branch were wrong, and the diagnostic they
added is what proved it: the macOS failure reported a stable
`rendered prefix: 6/15 ("VTERM_")` BEFORE and AFTER the CRLF change, with an
identical cursor, across two completely different child layouts. Identical
truncation under different layouts cannot be a layout problem.
The real mechanism is pinned by the repository's own unit test,
`cell::tests::diff_split_by_unchanged_cell_is_two_spans`: `cell::diff` splits
a run at any cell where `prev == next` and never transmits that cell. So when
a character of the marker already happens to sit at its destination, the host
receives the marker with that byte MISSING, not merely escaped around. The
constant 6 is the distance to the first such hole.
That makes escape-stripped matching unsound in kind rather than merely
insufficient: no matching strategy recovers a byte that was never sent. It is
removed, and `wait_for_output` is strict again. What remains asserted through
host bytes are protocol escapes pmacs writes directly — the OSC 52 clipboard
reply, the alternate-screen and bracketed-paste resets — which are not painted
cells and which the differ never touches.
Readiness now gates on a file the child publishes, the pattern the reliable
sibling test in this file already uses. That the child's output reaches the
SCREEN stays asserted in-process over `snapshot_text`, at the layer that can
actually see it; this test keeps what it uniquely owns, the host lifecycle.
`strip_ansi` and `longest_rendered_prefix` are kept as failure diagnostics
only, and now carry a case pinning the dropped-cell shape so the wrong remedy
is not reached for again. The new readiness wait reports startup breadcrumbs
on timeout; the plain helper reports only the missing path, which is the least
useful thing to know at exactly that moment.
Both the readiness gate and its timeout diagnostic were falsified by pointing
the child at a path the test does not watch.
Test-only; no runtime code.

- `listview.open`, `compile.run`, and `pmacs.terminal.open` all take the
same strict `display = "current" | "panel"`, validated before any
buffer, session, process, or wrapper exists. Omission keeps today's
behavior; Stage 3 flips the default.
- `listview.quit` / `compile.quit` delegate to `window.quit` only when
the buffer really is in a side window, so the presentation is deleted
or restored instead of leaving a source buffer stranded in the slot.
- LSP `visit_location`, LSP go-to-definition, and compile `visit_error`
route through `display_file`, so a visit from a panel lands in the
document target and fires its hook with that window active.
- `window.quit`'s Delete arm focuses the revalidated remembered origin.
- Capability fallback discards an accompanying `height` rather than
rejecting the call.
- `window.min-height` clamps a below-floor value on read instead of
refusing the write.
- `tests/bottom_panel_stage1_acceptance.rs`: 42 tests over the framing's
Stage 1 criteria, including the two production `Layout::compute`
callers, the recursive minima, hide/reappear, the final-focus matrix,
quit chains at the depth cap, per-frontend jump origins, the divider,
and a real-PTY pin of Bet B1.

The diagnostic added in the previous commit answered the question on its
first macOS run:
rendered prefix: 6/15 bytes ("VTERM_") — child text rendered only partially
So the child wrote and the host received part of the marker, but stripping
escapes did not rejoin the rest: other repainted cells sit between the two
pieces, not just cursor moves.
Six characters is exactly what fits before the right margin of this
session's 40-column child. The probe writes bare `\n`, and the supervisor's
PTY trampoline runs `stty raw`, which clears OPOST — so a lone `\n` moves
down without returning to column 1 and every line staircases five columns
right. After twenty lines the marker starts in the right margin, wraps
mid-word, and reaches the host as two pieces that no contiguous match can
join.
That also explains the intermittency: the wrap column depends on whether
pmacs has already resized the PTY from the requested 40 columns to the
window width, which races the child's first writes.
Write explicit carriage returns so every line returns to column 1 and the
markers start there. The fixture was wrong about its own line discipline;
the emulator was behaving correctly throughout.
The escape-stripped matching and the rendered-prefix diagnostic from the
previous commit are kept: they are what produced this answer, and they keep
the next such failure legible.

Stage 1 substrate for the bottom-panel arc (docs/bottom-panel-framing.md).
- `WindowParams` (side / fixed_rows / dedicated + implementation-owned
quit action and remembered document origin), `Side`, `QuitAction` with
a bounded replacement history, and the `MIN_WINDOW_OUTER_ROWS` floor.
- `Layout::compute(area, fixed)` allocates fixed rows before dividing the
remainder by weight; both production callers feed the same shared map,
including the peer-presence overlay pass that derives its own rect.
- `subtree_min_rows` / `interactive_min_rows`: the recursive minima, and
`boundary_below` for the shared drag / keyboard resize boundary rule.
- `FrontendView` gains `panel_capable`, `frame_geometry`, and the derived
`panel_hidden`, each spelled explicitly at every construction site.
- `EditorCore`: `primary_document_window`, the non-side target rule,
`display_buffer` + placement policy, `quit_window`, side-window removal
on `kill_buffer`, per-frontend jump entries with origin windows, and the
shared resolve/load-without-switch seam the initial-target bootstrap now
uses too.
- `EditorState`: the panel reconciliation transaction, geometry
declaration, the side-window `dispatch_idle_for` gate, divider paint,
and divider drag.
- `pmacs.window.display / display_file / quit / panel / params /
set_params / resize / display_target`, plus `builtin/runtime/window.lua`
with `window.panel-height`, `window.min-height`, and the resize commands.

The macOS `VTERM_ALT_READY` flake finally reported itself through #151's
breadcrumbs, identically in two runs: pmacs still running, `init.lua`
reached, `terminal.open` ok, and a settled screen whose tail is nothing but
`\x1b[22;42H` repeated 133 times.
That cursor is the evidence. A blank terminal parks at 1;1. Column 42 is
where the cursor lands after writing a 15-byte marker that ends at column
41 — so the child DID write and the emulator DID receive it. What failed
was the assertion: `wait_for_output` required the needle to appear as
contiguous bytes, but the TUI differ paints only changed cells and skips
ones that already match, so a run held contiguously on one screen row can
still reach the host as `PREF<cursor-move>IX`.
Match over escape-stripped bytes when the needle is plain text. This cannot
mask the failure that matters: text the child never wrote is absent from
the stripped stream too, so a genuinely silent child still fails. Needles
carrying their own escape (the OSC 52 clipboard reply) keep the strict path,
since stripping would consume the bytes under test.
The failure arm now also reports how much of the needle rendered, so the
next occurrence distinguishes "nothing reached the host" — a PTY/spawn
fault — from a partial render, instead of leaving a tail of pure escapes
that cannot tell them apart.
Both helpers are pinned directly, including that stripping rejoins a split
run without inventing absent text. `strip_ansi`'s first draft mishandled
`ESC ( B`, whose intermediate byte makes it three bytes rather than two;
its test caught that.

18 of the last 60 CI runs failed (30%), including repeatedly on `main`.
Every failure is macOS-only and hits BOTH Lua flavors, so it is the
runner, not LuaJIT. Sampling 7 showed only two tests.
**m8_9 outline budget** — `outline_5_level_100_entry_renders_within_100ms`
is a wall-clock budget observed at 147ms and 149ms against 100ms on
GitHub's shared macOS runners, while Linux lands comfortably under. The
measurement and its printout now always run; only the ASSERTION is gated
on `!cfg!(target_os = "macos")`, exactly as
`composition_overhead_under_ten_percent` already is in `src/editor.rs`
for the same reason. A real regression still surfaces on Linux, on the
perf gates, and in the number printed to the log.
**vterm PTY smoke** — deliberately NOT a timeout bump. Instrumenting
locally showed the failing wait completes in 40ms against a 10s budget
(250x headroom), while the genuinely tight wait in the same test (2.86s
against 5s) never fails. Four hypotheses were eliminated with evidence:
- python3 cold start: the sibling test at :494 spawns the same
/usr/bin/python3 with a TIGHTER 5s budget and passes in the very
runs where the smoke fails ("3 passed; 1 failed");
- config resolution: XDG_CONFIG_HOME is read straight from the env
(src/config.rs:49), no platform branch;
- a stalled idle loop: the run loop polls on a 60Hz frame timeout and
ticks the supervisor every frame (src/editor.rs:2522), so child
output drains without input;
- a too-small budget: see the 250x headroom above.
The real defect this commit fixes is that NONE of those could be
distinguished from the CI log, which carried only "host output never
contained VTERM_ALT_READY" plus a tail of escape bytes. init.lua now
writes breadcrumbs (reached / terminal.open ok-or-error) and the timeout
reports whether pmacs is still alive plus each breadcrumb, so the next
occurrence names its own cause:
startup: pmacs still running; init.lua reached="1"; terminal.open="ok"
Verified non-vacuous: forcing the needle to never appear produces the
line above, which also proves io.open works in pmacs's Lua — otherwise
the breadcrumbs would silently read MISSING and mislead.

Integrate folding Stage 2 and its landed-state documentation with the
protocol-v20 GPU initial-target branch. Preserve per-session fold projection
selection in the target bootstrap transaction and retain v19 compatibility
coverage after the later protocol bump.
Shut down bootstrap sockets on every dispatcher-side failure and reject
frontend events whose session state was never installed. This prevents a
lingering failed client from reaching absent render/size state.
Track target-side CRDT upgrades independently from load/create status so a
deduplicated hidden buffer is published to every existing grid replica. Add
real-daemon regressions for both failure containment and replica publication.
PR #149 review round 5, finding 1 — correct, and both round-4 bugs did
survive through the intercept path.
Round 4 moved the widening off the point and onto `edit_start_of(&op)`,
but ran it in `run_buffer_edit` BEFORE `run_managed_edit`. A managed
buffer intercept may legally rewrite `pos` / `start` / `end`
(`LuaInterceptView::intercept_edit`), so the requested op is not where
the edit lands:
- requested outside -> intercept relocates inside: the edit stayed
hidden;
- requested inside -> intercept relocates outside: an unrelated fold
opened.
The seam still covers BOTH paths — hooking only `run_managed_edit` would
let an interactive `bypass_intercept` edit escape, which is why the
framing put it on the common entry — but each path now keys on its own
effective site:
- `run_bypass_edit` applies its op verbatim, so `run_buffer_edit`
hooks it there;
- `run_managed_edit` hooks after the intercept chain settles and
before the apply, on the op the chain returned. A chain that raises
applies nothing, so it unfolds nothing.
The registry borrow is released at that point, and the helper reads only
`SharedCore` + the fold registry, so no borrow conflicts with phase 3.
Three new tests, all through real `M-x` with a real
`pmacs.buffer.add_intercept`: relocate-into-a-fold must unfold,
relocate-out-of-a-fold must not, and a rejected chain must not. Each
asserts the buffer text first, so the test fails loudly if the intercept
stops relocating rather than silently passing.

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

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

Implements docs/folding-stage2-framing.md rev 4. The daemon grid
renderer now consults the fold store: hidden lines are omitted, rows
below shift up, and every consumer that assumed
`display_row = source_line - view_top` routes through one shared
projection. No wire schema change and no protocol bump (Bet B6) — the
collapse is entirely daemon-side; the GPU path is Stage 3.
The spine (Q#FD12) is `src/fold_view.rs`: a `VisibleLineMap` derived
from `FoldRegistry::folds` plus a window's line offsets and never
stored. Its unit is a merged **hidden component** — overlapping OR
adjacent hidden intervals unioned, each keeping the one visible
`head_line` and that line's exact `head_position`. Adjacent intervals
merge because the later fold's head is itself hidden, which is what
makes nesting, shared heads, and crossing overlap all resolve to a
head that can actually render (round-3 F2).
Instances are short-lived and built **per rendered window** and **per
command/event operation**, never once per frame: `paint_frame` renders
several windows that may show different buffers, so a singleton would
leak one pane's folds into another (round-2 F2). The render instance
rides on a lifetime-bearing `Viewport<'a>` as `Option<&'a
VisibleLineMap>` — a shared ref is `Copy`, so `Viewport` stays `Copy`
(Bet B7).
Rendering:
- `TextView::render` walks visible lines; the head line gets a
trailing content-area ellipsis (Q#FD13).
- The gutter walks visible lines too: Absolute keeps the raw `line+1`,
Relative/Hybrid measure VISIBLE distance anchored on the cursor's
visible head (Q#FD14). The fold glyph takes the col-0 sign cell only
when a gutter exists — line numbers default to Off, so with no gutter
the ellipsis is the sole marker (Q#FD20, round-1 F3). A diagnostic
clamped onto the head wins that cell by paint order.
- A diagnostic on a hidden line clamps its SIGN to the outermost
visible head (most-severe merge); the squiggle needs a real row, so
only the sign clamps (Q#FD15).
- Caret, local selection endpoints, and peer cursors project via
`visible_position_of` — the head row AND the head's end-of-content
column, never an arbitrary column (round-2 F3). Peer presence derives
the RECIPIENT window's map.
- Style/search/completion overlays route through
`Viewport::row_offset_of`; the mode-line indicator reckons in
visible-line space.
Command/event time is scoped per frontend (Q#FD21): a
`fold_projection` flag on `FrontendView`, set at attach from the
negotiated `semantic_render` bit (grid ⇒ true, semantic ⇒ false until
Stage 3, LOCAL ⇒ true) and never inferred from a `FrontendId` (Bet
B8). Without it, shared `EditorCore` motion would make a simultaneous
unfolded GPU session's cursor skip lines it still displays. The map's
two axes stay separate (round-3 F1): the acting frontend supplies the
policy, the operation's TARGET window supplies the buffer — a wheel
event names a pane without activating it.
Motion (Q#FD17, ruled: include), paging, wheel, the click inverse, and
the auto-scroll clamp all step by visible lines under that gate;
motion from a hidden logical cursor normalizes to the visible head
first. `view_top` stays a source-line index (Bet B5), set only via
`clamp_view_top` so it never rests hidden.
Unfold widening (Q#FD19): the pre-edit unfold moves to the top of
`apply_active_edit` — one funnel that subsumes the six primitives'
calls and covers yank + query-replace, both of which place point at
the edit site first. Interactive Lua mutators hook the common
`run_buffer_edit`, above the managed/bypass split, gated on
`InteractiveCommandOrigin` AND the edit targeting that frontend's
active-window buffer. The remote/optimistic-CRDT path stays excluded
(Stage 3); undo/redo unfold stays deferred.
Acceptance: `tests/folding_stage2_acceptance.rs`, 35 tests asserting
on the real `paint_frame` cell grid, covering framing items 1–14
including crossing folds, a nested deeply-hidden cursor, a split of
two different buffers with an inactive-pane wheel, and simultaneous
grid+semantic motion.

Add protocol-v20 semantic bootstrap and readiness result framing so
`pmacs --gpu FILE` opens the requested path before the GPU window becomes
ready. Keep target identity scoped to the authenticated frontend, preserve
legacy/no-target attach behavior, and publish fresh buffers coherently to
existing replicas.
Carry Unix path bytes and launcher cwd through the root broker, resolve paths
lexically in the daemon, reuse or create buffers without ambient-view state,
and preserve the managed daemon lifecycle from #141. Add focused parser,
wire, lifecycle, hook, isolation, and real-connector acceptance coverage.
Round 2 correctly found the Finding-2/3 fixes were unpinned (reverting
them left the suite green). Both are now bite-verified:
- **Kill-path purge (Finding 2).** Replaced the direct
`forget_buffer(id)` unit test with
`killing_a_buffer_through_the_real_path_purges_its_fold_store`, which
drives `pmacs.buffer.remove` — the production route through
`after_buffer_removed` — and asserts the store is gone via the dead id
(BufferIds never recycle). Mirrors config_registry's real-kill-path
test. Bite-verified: reverting the `after_buffer_removed` fold branch
turns it red.
- **close-all point move (Finding 3).** Added
`close_all_command_moves_point_to_enclosing_head`, which invokes the
`fold.close-all` command with the point inside the second of two
top-level fns and asserts the cursor landed on that fn's head-line
content end (and both folds exist). Bite-verified: reverting close_all's
`maybe_move_point` loop turns it red.
- Ledger: `docs/active-work.md` folding lane now records PR #142 OPEN +
the two landed review rounds (was "opens once the gate suite is green").
Correction to the round-1 gate report: the acceptance suite is **21**
tests (round 1 was 20, not 24 — a tally slip), green under default and
`--features crdt`. Full gate suite otherwise green (fmt, clippy
--workspace --all-targets, git diff --check).

- **Finding 1 (bug):** a delete starting exactly at a fold's `end`
removed the `\n` that `end` names — the last hidden line's terminator —
but the strictly-after arm (`os >= e`) kept the fold, leaving a mid-line
end. `translate`'s after-arm is now `os > e || (os == e && old_len == 0)`
so a pure insert at `e` still stays outside while a delete at `e` falls
to the drop arm, symmetric with the head side. New unit test
`delete_starting_at_tail_boundary_drops_fold` (bite-verified).
- **Finding 2:** `pmacs.buffer.kill` didn't clean the fold registry.
Added `FoldRegistry::forget_buffer(id)` (id-keyed; the view died with the
buffer) and wired it into `after_buffer_removed`, mirroring the
keymap/config cleanup; the registry is now stashed as Lua app-data.
`forget(&mut Buffer)` is clarified as the revert/reload reset.
- **Finding 3:** `fold.close-all` now moves the invoking point to the head
when it closes a fold around it (Q#FD3); the data-API `fold` exemption
(programmatic, no invoking point) is named in the module doc.
- Nits: dropped the dead `!(both empty)` conjunct in `fold_state_msg`;
replaced the trivial fresh-registry assert; added coverage for the
stale-tree refuse via a fold command, the read-only-buffer rejection
(Q#FD11), and unfold normalizing an arbitrary range.
Gates green: fmt, clippy --workspace --all-targets, --lib (1786),
--features crdt (1962), folding_acceptance (24), m4 (skip basedpyright),

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

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

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.
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.

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.
Gates: fmt, clippy -D warnings, --lib (1683), --lib --features crdt
(1857), the new config_registry_acceptance (13) plus auto_pair (45),
editops (72), autosave (29) and m9_6 (25), m4 --skip basedpyright
(114), PMACS_REQUIRE_GPU=1 pmacs-gpu (109), the lua54 backend build,
and the full workspace sweep (2795 tests, exit 0). git diff --check
clean.
