feat(panel): flip the adopter default — Arc 7's last step
Stage 3 steps 3 and 4. Omitting `display` now resolves to the PANEL for
listview, compile and terminal; dired keeps `"current"`, passed
explicitly to the shared resolver. Per-adopter `select` per Q#BP12:
listview true, compile false (passive output must not steal document
focus), terminal true.

The census predicted 37 failures across 5 suites and the flip produced
exactly that — same suites, same per-suite counts. The measurement was a
prediction, not an estimate, which is what the inverted step order was
for. Final sweep: 3449 passed / 0 failed against a 3447 baseline, the
+2 being new pins.

THE CENSUS COUNTED FAILURES, NOT CAUSES. Thirteen listview failures had
ONE root cause: a panel is derived-hidden while frame geometry is
unknown, and listview_acceptance never declared any — it never needed to
while listview defaulted to the current window. One helper took it from
13 to 2. The same applied to m4 and vterm_stage2. Geometry is
authoritative state and a grid frontend's real frame size IS its
declaration; the panel suites have always said so.

THREE DEFECTS THE FLIP EXPOSED, each fixed rather than tested around:

1. The OUTLINE panel's `on_visit` used `pmacs.window.switch_buffer` —
   the RAW switch, which replaces the buffer in the ACTIVE window. That
   was harmless while the outline opened into a document window. Once
   the panel became the default the active window WAS the outline panel,
   so RET clobbered the panel with the source and left nothing for `M-,`
   to return to. The references panel was migrated to `display_file`
   when the arc landed; the outline was missed because nothing exercised
   it from a panel until now. Q#BP11c names this exact corruption, and
   both the outline and compile tests now assert `M-,` FOCUSES the
   panel rather than cloning its buffer into the document — an
   assertion the previous one could not distinguish.

2. `pmacs.compile._last` stored only `{cmdline, cwd}`, so a recompile
   reached `start_run` with no `display` and took the new default. A
   user who ran `compile.run{display="current"}` would be moved into a
   panel the moment they pressed `g`. An opt-out that reverts on the
   next recompile is not an opt-out; `display` is stored and replayed,
   with nil kept as nil so an omitted value still resolves to the
   default rather than freezing at the first run's resolution.

3. `opts.display` on a nil `opts` — my own regression, introduced by
   fix 2 and caught by `journey_acceptance`, which is exactly what that
   ratchet is for.

COMPILE'S CHORDS ARE NOW PANEL-LOCAL, and that is a contract rather than
an accidental reachability loss. Every compile chord is bound
`scope = "buffer"`, so with `select = false` none dispatch from the
document — `C-c C-k` included. `acc34` pins it, and pins that
`M-x compile.kill` still reaches the running slot from anywhere via its
`or compile_slot()` fallback. A global chord is a command-surface
decision and belongs in its own framing.

TEST CLASSIFICATION WAS PER TEST, NOT PER SUITE. Two neighbouring
compile tests land on opposite sides: acc15 (RET-visits-error,
jump-back) asserts the NEW default, while acc16 (n/p within compile
output) genuinely needs the buffer selected and says so. compile's
suite-wide helper opts out because ITS subject is compile-BUFFER
behaviour; the placement-subject tests use a second helper that takes
the default. Every opt-out states why. Nothing was mass-added to make a
suite green.

s1_12's two concerns are split as directed: it keeps its Q#GB18
name-keyed-identity bite with explicit `display = "current"`, isolating
the buffer-level `p.prev` skip rule, while a new `s3_1` pins the
side-window presentation chain — C → B → A → delete, ending at the
document with the wrapper collapsed. The mechanisms are complementary:
presentation history chains in the side slot; `p.prev` prevents
raw-switch and capability-fallback loops.

Verified: fmt, diff-check, clippy with and without crdt, --lib 1896,
--lib --features crdt 2081, pmacs-protocol 19, m4 149, required GPU 221,
and the full serialized sweep at 3449/0.

Levi Neuwirth fb14dc9ec3 test(isolation): migrate the corpus off the ambient roots
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`.

Levi Neuwirth 5d92348054 fix(editor-core): normalize rewritten selections
Adopt Q#GB6's clamp-or-clear rule in both window-coordinate
normalization paths. Preserve shortened selections, clear only those
collapsed by a moved endpoint, and pin both outcomes through the real
generated-write and view-rebuild callers.

Make listview refresh rely on the generated-write notification before
reseating, so Stage 1 criterion 7's fan-out mutation bites both
adopters. Align criteria 5, 11, and 12 with framing revision 7.

Levi Neuwirth 4da4830f80 fix(editor-core): drop a selection anchor a rewrite invalidated
Review finding 1 on PR #191. `notify_buffer_edit` clamped `cursor` and
`view_top` but not `win.selection.anchor`, and `rebuild_views_for` had
the same gap. Clamping the cursor is not enough to make the region safe:
`Window::region` orders `(anchor, cursor)`, so a stale anchor above a
clamped cursor is still the region's high end and `region_bytes` slices
the rope with it. Reproduced before the fix as
`assertion failed: end <= self.len()` at `src/rope.rs:145`, reached from
`EditorCore::clipboard_copy` after a generated rewrite.

The anchor is DROPPED, not clamped. A window must always have a cursor,
so clamping one is the only available answer; a window need not have a
selection, and a clamped anchor asserts a region boundary the user never
placed --- after a wholesale rewrite the surviving offsets address
unrelated bytes. This is not a new rule: `window.quit`'s restore already
answers the same question the same way with
`selection.filter(|sel| sel.anchor <= len)` (`src/editor_core.rs:3259`).
One rule, now three call sites.

Both exits are pinned separately, because fixing one and trusting the
other is how the gap arose: `acc16h` drives `notify_buffer_edit` through
a generated write, `acc16i` drives `rebuild_views_for` through
`pmacs.help.show_command`, which is the `*help*` renderer's real path.
Deleting either call site fails only its own test. The pin also
discriminates DROP from CLAMP, because that is the decision a revised
Q#GB6 could overturn.

The wording is marked PROVISIONAL in both the implementation and the
pins. The rule belongs to Q#GB6, and PR #188's approved revision 5 does
not mention the anchor; a revision request carrying this defect is with
that lane. If the landed revision says clamp or translate, this changes
to match rather than standing as a third description.

Also in this commit, review findings 2 and 3 --- the tree asserting what
the record does not support:

- Criterion 5's restatement is withdrawn in BOTH suites. The tests now
  quote the approved criterion, are renamed `*_provisional_*`, and say
  they do not satisfy it; the evidence (`ensure_writable` precedes the
  intercept chain, with the measured `ReadOnly` message) is recorded as
  what was sent to #188, not as a replacement contract. The framing's
  own bite is unchanged and still fails them.
- Criterion 7's "for each adopter" is restored: the listview half now
  exists as its own test. Its inability to carry the framing's mutation
  bite --- `window.switch_buffer` rebuilds the `TextView`, verified by
  applying the mutation and watching this half stay green while the
  dired half fails --- is recorded in the test and filed with #188,
  not resolved here.
- Criteria 11 and 12 are relabelled from `main` bites to mutation bites.
  Both fail on `main` only at their disambiguation premise and never
  reach the assertions they exist for, so a revert is not evidence for
  what they assert.

How a restated contract passed the previous gate run, since the next
lane can use this: nothing in the gate suite reads a framing document,
so a test that quietly narrows its criterion is indistinguishable from
one that satisfies it --- both are green, and `scripts/bite` only proves
an assertion bites some pre-image, never that the assertion is the one
that was approved. The gate can catch a test that does not bite; it
cannot catch a test that bites the wrong contract, so that check has to
happen where the criterion is read.

Levi Neuwirth e1b859fd4f feat(generated-buffers): dired and listview adopt the authorized write
Stage 1 of generated-buffer immutability
(docs/generated-buffer-immutability-framing.md, revision 5). Closes the
two families the bug is reachable on WITHOUT `M-x`: `compile.lua` and the
search panel rebind all seven undo chords to a no-op, but `dired.lua` and
`listview.lua` rebind nothing, so a bare `C-/` emptied a listing and a
panel. The cheap half is also the exposed half.

An intercept is not read-only. `Buffer::undo` reaches the rope through
`ensure_writable` and never consults the intercept chain, so the
erroring-intercept-plus-`bypass_intercept`-over-a-writable-rope idiom
guarded the edit path and left the history path open. Rebinding chords
does not close it: `M-x buffer.undo` is dispatchable on every buffer in
the tree.

- `dired.lua`'s `paint` and `listview.lua`'s `render` write through
  `pmacs.buffer.set_generated_contents` — lift the lock, whole-buffer
  replace skipping intercepts, discard history, re-assert the lock, fan
  the `Edit` out. Zero `bypass_intercept` writes remain in either file.
- Both keep their named erroring intercept and `set_round_trip_input`.
  The layering at `terminal.lua:351-366` is unchanged: the rope lock
  protects the daemon copy, round-trip input protects a semantic
  frontend's own mirror, and neither substitutes for the other.
- Q#GB13 — `listview.ensure_panel` stops adopting a same-named foreign
  buffer. Ownership is the `panels` table; a collision disambiguates
  `<2>`..`<99>` and raises at the limit, matching `dired.lua:476-504`.
  This is a prerequisite of the lock, not a follow-up: the arc removes
  the `M-x buffer.undo` that was the only recovery from a clobber.
- Q#GB18 — `panels` becomes a compacting list keyed by identity. It was
  written under the requested name and read back under the actual name,
  which a disambiguated panel breaks: `RET`, `g` and `q` fail closed and
  silently, and `listview.open`'s capture guard fails OPEN, capturing a
  panel as its own `q` target — the chained-panel loop its comment says
  it prevents. Ships in the same commit as the disambiguation by the
  framing's ordering constraint.
- Q#GB6 — `EditorCore::notify_buffer_edit` clamps each window coordinate
  against its own post-edit bound, unconditionally. `cursor` is a byte
  position bounded by `Buffer::len`; `view_top` is a line index bounded
  by `TextView::line_count`, and a replace can grow in bytes while
  collapsing lines, so "the buffer shrank" is not a usable trigger. This
  fixes a shipped defect that reaches terminal copy mode.
- Q#GB16(a) — locking these families disables fold CREATION on them,
  because `document_bytes` is spelled `is_read_only()`. Accepted and
  stated rather than shipped silently; the status string now names the
  read-only lock instead of claiming "not a document buffer".

Acceptance: 10 new criteria in `listview_acceptance` (16 total), 6 in
`dired_acceptance` (31 total), 2 in `terminal_copy_mode_acceptance`.
Every criterion's falsifying mutation was run: 5 bite by revert against
`githubsucks/main`, 9 by a named one-line mutation.

Two framing corrections, both recorded in the tests rather than worked
around silently:

- Stage 1 criterion 5 is unreachable as written. `Buffer::apply_edit`
  (`src/buffer.rs:773`) and `begin_edit` (`:725`) call `ensure_writable`
  as their FIRST statement while the intercept chain runs later inside
  `apply_edit_inner` (`:1072`), so once this arc's lock is installed an
  ordinary edit can never reach the intercept. Restated at the one point
  where the two are distinguishable — the lock lifted — which is the
  state the intercept genuinely still covers.
- Criterion 7 cannot bite at the listview adopter. `listview.refresh`
  and `listview.open` both follow `render` with `window.switch_buffer`,
  which rebuilds the `TextView` from scratch and masks a dropped
  fan-out. `dired.revert` does not, so the dired half carries the bite;
  it fails under the mutation with the reported
  `assertion failed: end <= self.len()`.

Levi Neuwirth b25b47334d feat(panels): listview module, Q#P6 round-trip seam, references panel
Arc 1b phase 1 (framing: docs/lsp-panels-framing.md).

Q#P6 (the one Rust change): EditorCore.round_trip_buffers +
pmacs.buffer.set_round_trip_input(buf, on); dispatch_idle() reports
false while a marked buffer is active, so semantic frontends'
optimistic-apply stays off -- RET reaches a panel's buffer-local visit
binding instead of locally inserting a newline, and typing dispatches
into the edit path where the read-only intercept rejects it (a CRDT
import would bypass the intercept chain entirely). Pruned on kill.

Q#P1/P2/P3: builtin/runtime/listview.lua generalizes the *buffer-list*
idiom -- pmacs.listview.open{name, header, rows, on_visit, on_refresh}
owns ensure-buffer (recreates if user-killed), wholesale render with
bypass_intercept, line->item map, buffer-local RET/SPC/n/p/g/q keymap,
previous-buffer capture + q restore (never another panel; scratch
fallback), cursor re-seat after render, the read-only intercept, and
the Q#P6 mark. Panels are buffers: both frontends render them with
zero protocol change.

Q#P4: lsp.find-references (M-?) opens *references* -- one row per
location, paths shortened against the project root, RET visits via the
shared SP-4 template (jump ring, find_or_open, cursor walk; extracted
as visit_location for the phase-2 outline to reuse).

Acceptance: tests/listview_acceptance.rs -- open/seat/visit, header
non-visitable, q restore, read-only rejection, dispatch_idle gate,
refresh re-render + re-seat.
