The mechanical half, riding on the census in the previous commit.
* 342 in-process construction sites in 65 files now take
`new_with_roots` / `open_with_roots` with `iso::roots()`. The isolated
base is a pure function of `CARGO_TARGET_TMPDIR` — no counter, no
`OnceLock` — so two copies of the module in one binary agree instead of
racing, and the tree lives somewhere `cargo clean` owns rather than
leaking into `/tmp` once per run. It is shared deliberately:
materialization is content-gated and idempotent, so a per-test
directory would repeat it ~330 times per run for a byte-identical
result.
* `journey_acceptance` keeps the ambient `EditorState::open`, because
proving the production entry point has a caller is the whole of what
that ratchet is for. Rev 2's "isolated by the environment its binary is
launched with" was not a mechanism — cargo launches each test binary
with the caller's environment, and a binary cannot re-point its own
roots before its tests run. Each test is now a thin parent that
re-execs this binary for its own name with controlled roots, and the
child runs the body against production's call. Two pins guard it: the
child asserts all four roots resolve inside the controlled base, and
the suite asserts against its own source that it has not quietly taken
the seam. The parent also asserts the child ran `1 passed` — a stale
`--exact` filter would otherwise hollow the whole thing out silently.
* The shared spawners take all five storage variables.
`spawn_daemon_process_with_env` set `HOME` and `XDG_CONFIG_HOME` only;
`HOME` is a FALLBACK, so it isolates a root only while the matching
`XDG_*` is unset — the harness's apparent adequacy was a property of
one developer's environment. The PTY spawner backfills whichever of the
five its caller did not pin. The 10 direct `Command::new` daemon and
attach spawns get the same treatment.
Three suites had `mod common;` behind `#[cfg(feature = "crdt")]`;
`common::iso` is needed in every build, so those are ungated. Files that
already pull in `common` reach `iso` through a `use` rather than a second
`#[path]` declaration — loading one file as two modules is
`clippy::duplicate_mod`.

Make the statusline and Vterm Stage 3 acceptance suites track the
bottom-panel v21 bump, including the real daemon and headless GPU probe.
Record the full gate result and the unrelated stale directory-target
assertion reproduced on canonical main.
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.

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.
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.
Vterm Stage 3 — the final vterm stage. A semantic frontend can now host a
terminal: the daemon ships complete validated cell grids, and pmacs-gpu
renders them with fixed-cell geometry, its own input path, and no document
projection at all.
Protocol v19 appends three variants after their enums' final v18 members:
InstanceMessage::TerminalFrame (daemon-gated), and FrontendEvent::
TerminalResize / TerminalPointer (frontend-gated). It is the first bump to
gate in both directions, so criterion 28 pins each filter independently and
byte pins on StatuslineSegments and MenuPointer guard the placements.
pmacs-protocol gains src/terminal.rs: the shared row/column/visible-cell/
grapheme/metadata bounds, TerminalProcessState, TerminalSelectionSpan, and
TerminalFrame::validate — the ONE structural policy the daemon runs before
emission and the frontend runs after decode. src/terminal/* re-exports them
so no duplicate type exists, and unicode-width becomes a workspace dependency
so the screen and the validator measure glyph columns with one table. A new
8 MiB aggregate glyph bound keeps the largest legal frame (measured:
13,437,863 bytes) under the unchanged 16 MiB transport cap rather than
widening every connection's allocation ceiling.
The semantic producer suppresses the whole document family for a terminal
buffer while keeping the status band, theme, font, statusline, menu, and
minibuffer, and compares the complete ordered payload rather than
screen_generation — scroll, selection, and process state all change without
advancing it.
Two things the framing did not spell out, both found by the real-daemon
acceptance:
The Viewport gate keys on the authenticated source's ACTIVE buffer, not the
buffer the message names. Viewport also aligns the window to what it
declares, so a stale document viewport in flight when a command opened a
terminal dragged the frontend straight back off it: the window oscillated,
every terminal declaration was refused, and no frame ever arrived, with
nothing logged anywhere.
The producer clears terminal mode on every exit path. The daemon uses that
flag to suppress CursorByte and the presence sweep, so an early return that
left it set kept both suppressed after the frontend returned to a document.
pmacs-gpu/src/terminal.rs is a pure cell-space paint planner, unit-testable
without a GPU. The renderer builds one shaped buffer per text run, so a wide
or cluster glyph's advance can never choose the next column's origin.
Criterion 37 needed a seam rather than a fixture: pmacs-gpu depends only on
pmacs-protocol, so attach::connect's reader sink was generalized and a
--headless-probe mode added. The acceptance drives a real daemon, a real
/bin/sh child, the real attach client, and real composited pixels in one
path — which is how both defects above were found.
Gates: fmt; strict workspace clippy; 1,757 default + 1,933 CRDT library
tests; vterm Stage 1 9/10, Stage 2 4/4, Stage 3 4/5 acceptance
(default/CRDT); statusline 7/8; M4 120; required GPU 127; workspace sweep
2,919 across 83 suites; diff check clean.
Resolve post-main integration drift in authenticated routing, terminal view projection, Lua installation, and inherited acceptance callers. Preserve the terminal statusline provider alongside the landed Themes provider and record the final Stage 2 gate evidence.
