A notice is an overlay now, which is the one place it is NOT like the
tree-sitter context: it takes no row from the body and moves no text. Each one
is a chip as wide as its own message plus a blank cell either side, anchored
to the pane right edge on the body top rows. The rest of each of those rows is
ordinary body text that still reads and still answers a click -- Notices.left
records where each chip starts, and the hit test refuses only the cells it
covers rather than the whole row.
The width is counted in GRID columns rather than scaled into the tagline face
the chip is drawn in, because the canonical grid is what a terminal client
draws and a chip narrower than its own text there would clip it; the narrower
tagline face simply leaves a little more room inside the chip. The tag layer
takes the geometry the grid pass already chose, so the two cannot disagree and
the GUI skipping the cells a tag layer covers leaves no stub behind.
Pane.body_offset is gone with the reservation it existed for, and bodyTop
takes only a rect. The body layer keeps every row it had, the scrollbar runs
the full body again, and the GUI smooth-scroll extents go back to the pane.

A message, a leader chord and a prompt used to share one row of body text at
the bottom of a pane, wearing the tagline font and nothing else about a
tagline. Now each one is a TagLayer of its own, emitted through the same
renderHeaderLayer the pane and column tags go through, so it gets the tagline
height, the small-font metrics, the band offset and the border for free --
none of which a body-grid row can have by changing its font role. The text is
right aligned. The prompt stays on the canonical grid because it owns a
cursor, and a cursor has to sit on a real cell.
The body starts BELOW the bands rather than under them, the way tree-sitter
context rows already worked. Pane.body_offset is how many rows they took and
Pardes.bodyTop(pane, rect) is the one place that answers "where does the body
begin" -- replacing fifteen copies of `if (tag_bottom) r.y else r.y + BOX_H`
spread across the paint, hit-test, scroll, PDF and image paths, which is what
let the bands and the text under them come adrift. Every notice is painted on
the grid as well, because the grid is what a terminal client draws and a band
it cannot see is a message it never gets; the GUI skips grid cells a tag layer
covers, so nothing is drawn twice.
Three bugs the bands exposed, fixed here:
- a prompt band flush with the right edge put its caret one column past the
pane, which the detached wire refuses -- so every frame was dropped for as
long as the prompt was open. The band now reserves that column.
- a click on a band mapped to Sel row 0, which is the TAG row: clicking
chrome expanded a word out of the tagline and ran it as a builtin.
- a watched file reloading under the editor changed the core without going
through update, so needs_frame was never set and the reload was never
drawn. Pardes.invalidate() is the name for that, and the file and theme
reloads call it.
A session can now drive its own 9P namespace instead of being refused one:
ownMountSuffix answers what a path names inside this editors own tree and
resolve, readLimit and write serve it from memory rather than making the
syscall that never returns. The match is anchored to whole components under
the registrys 9p/pardes/<name>, because a bare /pardes/<name> anywhere in a
string would claim ~/src/pardes/<name>/README -- and, before write learned the
same trick, write the trees bytes over the real file. readFileLimit and
writeFile refuse instead, having no core to answer from.
A toggle setting SETS when given `on` or `off` and only flips when it is bare,
so the report LocationsConfig prints can be fed back as configuration and mean
what it says.
Snapshots: 97/98, from 0/98. The goldens were several commits stale and 17
scripts had stopped running; `config <line>` is a new script command that
appends to the per-script startup config, so a script that clicks body
coordinates pins `Verbose off` instead of counting the rows an announcement
moves. nested-optout is left failing on purpose: two levels of nesting prepend
vaxis F3 codepoints to typed lines, which is a real bug and is written down in
docs/divergences.md with a repro.

Opening a path inside this editor's own 9P tree hung the session outright, and
it is easy to do by accident: a file manager whose $EDITOR is pardes, or a Look
at anything under /mnt/9p/pardes/<me>/. The realpath, the stat and the read all
leave through the mount and come back as 9P requests only this editor's loop
can answer, while that loop is blocked making them. The filesystem then stops
answering anybody, which is what made it look frozen rather than slow.
The answer has to come from the NAME, before any syscall, because the syscall
is the thing that never returns: the listener notes the name it is posted under
and `resolveOs` refuses a path containing `/pardes/<that name>/`, with
`readLimit` refusing it too for anything that gets past resolution. Another
session's mount stays perfectly usable, and `/n/self/...` is the way to reach
your own tree -- the editor serves it from memory without leaving the process.
Reproduced before and after: the 9P write that never returned now returns, the
editor stays responsive, and it spends four CPU ticks doing it.
The transient lines also now look like what they were modelled on. They carried
the context band's bookkeeping -- one list, rows reserved the way sticky
headers reserve them -- but still painted as ordinary body text, so a message
read as a stray line at the bottom of the pane rather than as part of its
chrome. They take the tagline font and the tagline's own colours now, verified
on a running editor: the announcement lands with font_role=tagline.
Two tests the features never had: a builtin announcing itself, reaching the
notice list, being overridden by Msg's own text and silenced by Verbose; and
the own-mount guard, including that a session with no listener refuses nothing.

The registry sweep could delete a live socket, anywhere on the filesystem. A
reviewer reproduced it: a socket that is bound but has not reached listen(2)
answers ECONNREFUSED exactly like a dead one -- that window is every server's
startup -- and the sweep then followed the entry's symlink and unlinked
whatever absolute path it named. It now follows a target only into the
directory our own sockets live in and only to a `pardes-9p-*.sock` name, it
re-probes immediately before deleting rather than trusting a probe that is by
then several syscalls old, and a readlink that exactly filled its buffer is
treated as the truncation it is. The test grew a case for an entry whose
target is not ours: the entry goes, the file does not.
Ctrl-V in raw tty mode was a black hole when the yank register was empty --
neither typed nor forwarded -- so vim's visual block, readline's quoted-insert
and every other program's Ctrl-V simply vanished. With nothing to paste the
chord belongs to the program again.
The lone-ESC flush added earlier was dead code. vaxis already returns Escape
for a one-byte 0x1b (`Parser.parseGround` asserts `input.len == 1`), so the
carried byte it waited for can never exist; a reviewer showed a 3 ms gap and a
60 ms gap behaving identically. Removed rather than left to imply a guarantee
it never provided.
A shell whose editor is gone can start one again. Naming a live but
unreachable session made `pardes <file>` exit 1, which let a stale environment
variable lock someone out of their own editor; it falls through to an ordinary
session, as it did before the variable existed.
Also: the macOS ABI check for `pardes_topbar_pane_border_px` had been replaced
by a duplicate of the line above it; `--startup` now fails on a leak the way
every other measurement in that file does, and stops calling its maximum a p95
below twenty samples; the served README and the skill no longer tell you to
write to `data` with `>`, which truncates the whole body before the write
lands; `docs/v9fs.md` described the allocate-on-walk design that was rejected;
and `test/fs.py` keys nesting off `PARDES_PID`, so its forwarding case stops
passing only when the runner happens to be inside a live pardes.
fs-test now reaches its one documented pre-existing failure instead of dying
early. Suite 778/783 with the two known crashes.

A 9P round trip on a local Unix socket cost 9.7 ms against the SDL shell and
0.758 ms against the terminal one. The server was not slow and the wake was
not broken: instrumenting the path showed every request waking the loop early
(wakes=210, woke_early=212, timed_out=38 over 250 ticks) and being answered on
that same pass. The cost was that `pump` answers 9P at one point in a loop
that then renders and presents unconditionally, so a client's next request
landed while the main thread was blocked on the display, and each round trip
therefore cost a whole frame. The frame rate was governing something that has
nothing to do with drawing.
`Pardes.needs_frame` starts true, is set by every event except a tick with
nothing animating and a filesystem request that only reads, and is cleared
once a frame is presented. `pump` returns before render and present when it is
false and nothing is animating. An idle editor answering reads now draws
nothing at all.
9P read_fid, one RPC: gui 9.7 ms -> 0.056 ms (173x)
tty 0.758 ms -> 0.062 ms (12x)
Verified the shells still paint rather than going quiet: the rendered screen
carries the opened file, a write through 9P redraws within the frame, and
`fs-discovery-test` passes over the real wire. Suite unchanged at 778/783 with
the two pre-existing crashes.
Also from the adversarial review of the previous commits:
`pardes --tty FILE` silently discarded the file, and `--tty MISSING` silently
discarded the error pane. main.zig named the boot layout before the positional
was resolved, and naming one short-circuits `Boot.of`. The choice now happens
after the argument is known, and only when there is no file and no missing
word. macos.zig names the same layout, so the app no longer boots a different
one from the terminal and SDL shells.
`pre_close_last_pane_tail` was transcribed from the NEW default rather than the
old one, so the upgrade path it was added for did not exist: a workspace dumped
before the tagline reorder came back with the old default welded on as a custom
tail. It is now the string it claims to be.
A pane two rows tall lost its message and, worse, its prompt and the cursor
with it. The notice cap keeps the LAST notices now, because the prompt is last
and a prompt you cannot see is one you type into blind.

A pane's message, its pending leader chord and a prompt waiting for input all
wanted the same row above the tagline. The prompt won it, the leader drew over
whatever was there on the right, and renderBodyLayer recomputed "is anything
down there" inline to reserve a single row. Three claimants, one row, and two
places deciding.
Pane.Notices is that decision in one place: a short ordered list of the lines
a pane is showing, rebuilt every frame by collectNotices from the state that
owns each one. The body layer reserves exactly notices.len rows, the way it
already reserves rows for sticky context headers, and the paint pass walks the
list and gives each line a row of its own, stacked upward from the tagline.
Nothing stores a second copy of the truth, so a line that goes away is simply
not added next frame and the rest close the gap. One notice lands on exactly
the row the message always had, and the prompt stays nearest the tagline so it
keeps its cursor.
Last also learned what to do when the jumplist is empty. It used to walk the
jumps and, finding nothing, do nothing at all -- which is the ordinary case
for a pane that opened beside this one and was never focused, such as the text
pane the bare tty layout puts under the shell. It now falls back to
neighbourPane: the next pane down the column, wrapping, and any other live
pane failing that. Alternating with the neighbour is what Last is for.

Pty children are exec'd with their own TERM/COLORTERM/TERM_PROGRAM instead of
inheriting a .app launch's empty environment, and ttyTaken finally answers on
darwin — libproc walks the tty's foreground process group — so Escape reaches
the child and Exec stops believing every pane sits at its prompt. The
occupancy suite runs on both platforms now.
The workspace tag row moves into the native menu bar as a Builtins menu.
-Dworkspace-tag (default off for -Dplatform=macos, on everywhere else) drives
it, and Pardes.topBarHeight replaces the TOPBAR_H constant so the core stops
reserving the row.
The view pins every variable-font axis to the file's own default (Maple Mono
came up Thin otherwise), shapes ligatures, carries per-shape pointer cursors,
and draws the look-hover affordance as refracted glass. Tag rows fill edge to
edge, with the anchor box painted back on top of that fill and its mode glyph
centred on the same square. Theme accents re-saturated across the set.

The 9P tree stops being a command language wearing a filesystem. /new
created a pane as a side effect of a *read*; it is now Tcreate in /pane,
with Tremove to close, which cloud9's engine has always supported and the
editor never declared: tree.zig now says
`features = .{ .create = true, .remove = true }`. Eleven pane ctl verbs
become files that can be read as well as written -- dot, limit, dirty,
mark, scroll, look, exec -- leaving ctl with `get`, the one verb no file
would say better. Root /ctl splits into a read-only /status and the
/look and /exec files whose write IS the click. stat carries real sizes
where it used to answer 0, and qid versions track a pane's revision, so a
client can poll for change without re-reading the body.
Commit a624a56 moved raw-tty keys to an early-return branch that knew only
Ctrl-B and bare Escape, and in the same edit deleted the paste branch below
it. That cost Shift-Escape (the unconditional way out of tty mode) and both
paste chords: Ctrl-V and Ctrl-Shift-V reached the child as keystrokes, so an
agent CLI running in a pane took Ctrl-V for its image-paste binding and
answered "No image found in clipboard". Both are restored, with tests.
Nested detection was not subtly broken but deleted: 60367d8 removed
nested.zig's process-ancestry walk and left "am I inside pardes" derived from
PARDES_FORWARD_LOOK, which read "0" both for --nested and for "the listener
did not come up". PARDES_PID now answers that question on its own, checked
with kill(pid, 0); PARDES_9P and PARDES_PANE answer how to reach it; the flag
is gone. The posted-9P registry also self-heals now -- a session that aborts
cannot unlink its own socket, so posting sweeps entries whose target refuses
a connection, symlinks only and on a definite ECONNREFUSED only.
Elsewhere: tty scrolling is sticky-bottom, following new output only from
the last row, with typing and entering raw mode snapping back to live; the
boot layouts are a Boot enum instead of a chain of ifs, and the bare tty
startup (Boot.tty, which main.zig names) opens an empty text pane under the
shell while tests keep Boot.tty_shell; builtins announce themselves on the
message row under a Verbose setting that is on by default; Config prints
each setting the way you would type it back, so WindowOpacity 70 rather than
"WindowOpacity: 70%"; LocationsConfig opens its window only when called bare;
every tagline puts the word that closes the thing last, and a column now
outlives its panes -- closing the last one leaves an empty pane, and only
Delcol, newly on the column tagline, takes the column away.

src/9p.zig shrinks to an 88-line alias: the engine and the backend contract
(Req, Reply/ReplyWith, Op, Status, Attr, E, error strings) now come from
cloud9.fs. The editor's limits become cloud9.fs.Options values; the ESP32-P4
board backend drops its own copies of the contract types. No behaviour
change; fs-bench still allocates nothing per request. cloud9 re-pinned to
the commit that carries the engine.

The served tree loses the self/ level: /index /ctl /new /log /screen
/listeners /pane/<n>/... /os, with /src only in -Dembed-sources=true builds
(default off, on for esp32p4). ctl speaks the editor's own language with two
lowercase verbs, look TEXT and exec TEXT, plus acme's addr verbs; the new/
factory directory becomes one clone file; cons is gone (exec Msg); name and
sel are files; stats report real lengths, modes and mtimes; /log streams
pane new/del/rename/save events. The tree code lives in src/ninep/
(tree, pane, ctl, addr, pty, events, screen, sources); fs.zig keeps host
access, mounts, resolution and find/grep. Same engine and transports.
README (fs-help.txt) and docs rewritten; tests updated and extended.

The tag's first character moved to TAG_TEXT_INSET when the grip's hit area was
separated from the text by a gap; the assertion kept reading GUTTER, which is
now the gap itself and carries the plain tag background. The test's own point —
that a preview on the tag's first character is paintable at tag column zero,
PREFIX_W being a body concern — is unchanged; only where column zero is moved.

A swipe that was still moving when the fingers lifted stopped dead. The dial
next to it has thrown properly since pardes_rotate_end, and this is that same
curve on the scroll accumulator: velocity sampled between events off the
monotonic clock, weighted toward the newest sample because a flick is decided
by how the hand was moving when it left, and a fling that ramps up from zero
at the floor rather than switching on at it.
A coast stops at the end of a document rather than spinning its remaining
velocity against the edge, which is why spendScroll now reports whether the
pane moved and why paneAt is public. Only a step that delivered a press can
report an edge — the many steps between two rows cross nothing.
Nothing suppresses AppKit's own momentum, and nothing needs to: its momentum
events are ordinary pardes_scroll calls, every one of which cancels the coast
before spending its travel, so on a real trackpad the system takes the gesture
over about a frame after the lift and the tail it ends on is below the floor.
This is the path for devices AppKit does not fling for — and the only one a
script can reach, since NSEvent phases have no public constructor.
momentum.snap asserts both halves, which is why it needs the long scrollback:
a flick with no document left proves nothing. A slow swipe is byte-identical
after the release; a hard one coasts twenty-four rows further on its own, and
a finger back on the pad stops it there.

+Grep, +Search and every language answer render rows like
src/look.zig:718:12-16 fn grepText(path: []const u8, text: []const u8...
— a location, a space, and a piece of some file. The location names the file,
the file names the grammar, and the rest of the row is a fragment of that
language, so a grep over Zig reads as Zig and one Markdown row in the same
buffer does not pretend otherwise. The location itself is left uncoloured: it
is not code, and painting it as code is how a path starts looking like a
keyword.
`look.parsePathLine` decides what counts as a location — the same primitive
n/N already walks these buffers with, so the two agree by construction about
which rows are locations. NOT `lookableLineSpan`, which is n/N's whole
heuristic: it calls `resolve`, and a `realpath` per row per scroll is not
something a render path can afford. A bare filename is refused too; only
`path:line` counts, or a prose line whose first word ended in `.md` would
colour the rest of a sentence.
THE BUFFER IS COLOURED WHOLE, ONCE, WHEN IT IS FILLED. An adversarial pass
measured the obvious per-window implementation and it was untenable: the rows
are independent, so a window pass buys no fidelity, only amortisation, and
pays a burst on every scroll that outran the covered range. Grammars compile
their highlights query on first use — zig 26.9ms, cpp 18.9ms, rust 14.3ms —
so a polyglot grep showing six languages stalled a frame by 66ms, moving a
cost the syntax module had deliberately put on "opening a file" onto a scroll.
It also raised tree-sitter's allocation rate 3.5x (8,785 per refresh against
2,454) into a 16 MiB bump arena that only reclaims LIFO, so ~16 scroll
re-highlights exhausted it — and that arena is shared with real file panes, so
a results pane could evict editing. A grep is capped at 512 rows; colouring it
once makes the covered-range check true forever after and scrolling free.
The rest of that pass, in the same spirit: injections off for a single row
(both build a SECOND parser, per fenced block and per inline node, which is
absurd for one truncated row that almost never contains a fence), one query
cursor for the buffer instead of one per row, a one-entry extension memo so
non-matching rows stop paying a 29-spec scan, and NO highlights at all when
nothing painted — an all-zero run is not the same as none, and it defeated
`recolorSyntax`'s fast path, making every +Help and +Config walk its graphemes
every frame to paint nothing.
One correctness bug from the same pass: a failed `setLanguage` has already
nulled the parser's language, so leaving `held` on the previous grammar made
every later row of it skip the call and silently lose colour.
Documents keep `.source`: a New scratch and a real file are output-shaped but
have one language and an edit per keystroke, and `saves` is the line between
the two.

A message row is cleared by the next keystroke, so anything reported while you
were looking at another pane was gone before you could read it — a save that
failed, a watcher's reload, a builtin's complaint. `setMessage` now records
into a fixed ring first: no allocation and no failure path, because it sits
underneath `reportError`, which is reached from sites that are reporting an
allocation failure. `Messages` (`SPC h m`) reads it back oldest-first.
Three things an adversarial pass found, each of which defeated the feature:
PROGRESS IS NOT A MESSAGE. A language server emits `Indexing 47%` several
times a second, and every tick is a distinct string BY CONSTRUCTION, so no
de-duplication can collapse it: at the client's one-per-150ms throttle it
takes about nineteen seconds to push every real message out of the ring. A log
that one indexing run empties is not a log. That path is `setStatus` now —
the row, and nothing else.
THE CLOCK MADE EVERY HOST MESSAGE UNIQUE. `message.stamp` prefixes `HH:MM:SS`,
so `saved /x.zig` at 14:32:07 and at :09 compared unequal and the ring filled
with rows that look identical and each say (x1) — exactly the case the
de-duplication exists for. It compares `message.body` now, the row without its
clock, and the newest wording wins so the row carries the last time it
happened rather than the first. It also keys on the PANE (one pane's failure
must not be recorded as another's) and compares the truncated form, so two
identical messages over 256 bytes stop being two rows.
AND THE CAPACITY BELONGS IN limits.zig. 128 entries is 32.75 KiB that is
allocated whether or not anybody reads it — 8.5% of the ESP32-P4's whole
384 KiB heap, about the size of its effect ring. The board takes sixteen.
The builtins/leader goldens move because the listing gains a row, and
builtins.snap middle-clicks a SCREEN COORDINATE that Tutor moved out of; both
updated selectively and verified against a fresh run.

`|` was the only one of helix's five. The other four differ in exactly two
things — whether the selection is stdin, and where the output lands — so they
are one action carrying a `PipeBehavior` rather than four code paths:
| stdin is the selection, output REPLACES it (had this)
A-| stdin is the selection, output discarded shell_pipe_to
! no stdin, output inserted BEFORE each selection shell_insert_output
A-! no stdin, output appended AFTER each selection shell_append_output
Each arms the same visible tag-tail prompt with its own marker (`|`, `|-`, `!`,
`!+`) so the prompt says which one you are in — they take the same command line
and do very different things to the buffer.
Two helix rules came with them. A behaviour that sends no stdin runs the
command ONCE and every cursor gets that one answer (helix's `shell_output`
cache): ten cursors and `date` give ten identical stamps rather than ten forks
racing to produce one. And a command that put a trailing newline on a selection
which did not have one has it taken back off — that is what keeps a one-line
`| tr a-z A-Z` from becoming two lines. The existing multi-range test moved
with that rule and now pins it deliberately.
In all three writing behaviours the OUTPUT is what ends up selected, keeping
the original range's direction, so an operator can follow straight on from what
the command just produced.
`$` (`shell_keep_pipe` — drop the selections whose command exited nonzero) is
still missing: it needs a per-selection verdict and the runner's answer is
atomic. Noted in docs/helix-keys.md beside the `$` divergence already there.

Two things made the selection pipe feel like it had never worked. It runs —
test/snapshots/pipe.snap drives the real binary through a pty and filters
`alpha beta` to `ALPHA BETA` — but it had no way to tell you when it did not,
and one of its failure conditions was not a failure at all.
IT NOW SAYS WHY. `runOne` read the command's stderr into memory and freed it
two lines later, unread; every caller answered a failed filter with a bare
`return`; `pipeResponse` had eight more silent exits under that. So `| trr`
(a typo), `| grep nomatch` (exit 1), `| jq .` on bad JSON — all did nothing,
said nothing, and left the text alone with no way to find out why. The runner
carries a `Failure` home instead: which selection, what became of the command,
and its own stderr. The core turns that into an `+Errors` buffer — acme's name
for output that came from the program rather than from a word anybody clicked:
| trr
exit status 127
sh: line 1: trr: command not found
An output buffer rather than the message row because the useful half of a
shell failure is the text the shell wrote, and a 256-byte row would keep the
label and throw away the reason. Focus stays with the file: `openRead` moves
`p.active` to what it opens, which is right for a Grep you asked to read and
wrong for a report you did not — you want to fix the command and press `|`
again. A host with no `pull_pipe` at all (the detached daemon, the browser,
the board) now says that too, instead of answering failure into the void.
`| head -1` NOW WORKS. `writer_context.ok` was part of the success condition,
so a command that stopped reading its stdin failed the filter even though it
had done exactly its job: `head` takes the line it wants and closes the pipe,
the write gets EPIPE, and a selection bigger than the 64 KiB pipe buffer was
enough to trigger it. helix joins its input task and ignores the result for
this reason; the exit status is the whole verdict. Also reported rather than
swallowed: the ten-second timeout, the output ceilings, and a file edited
while the filter ran — one keystroke during a slow command used to discard the
result in a way indistinguishable from the filter doing nothing.

Both acme chords read the PRIMARY range and dropped every other cursor on the
floor — the one thing a multi-cursor editor must not do with a command the user
aimed at all of them. They are also structurally outside the machinery that
would have handled it: the Enter/Tab chord is intercepted before `handleNormal`
so it never becomes an Action with a scope, and `runBuiltin` bails on
`multiOnce` anyway, because a builtin is per-keystroke rather than per-cursor.
So `chordEachSel` takes the `submitPipe` shape instead: `paneRanges` once,
forward in document order, every range's bytes COPIED before the first builtin
runs. The copy is not caution — a `Look` opens panes and an `Exec` can run a
builtin that edits or closes the pane those offsets point into, and a selection
whose text is `Del` is a legal Exec. The loop re-checks the slot and its serial
between iterations, the same guard `replaySels` makes for the same reason. With
one cursor it returns false on the first line and the old path runs untouched.
FOCUS FOLLOWS THE PRIMARY. `lookAt` sets `p.active` for every target it opens,
so `Look` over four selections used to leave you at whichever one happened to
sort last — an accident rather than an answer.
...AND A LOOK WITH NOWHERE TO PUT ITS ANSWER SAYS SO. All four slot checks in
`lookAt` were a bare `orelse return`: with one selection that merely felt like a
dead key, and with several it means "I opened nine of your fourteen and told you
nothing". They report `NoPaneSlots` now, through the channel output_pane.zig
already raises it on and a test already pins. The three openers report their own
failure too, so a file that will not open says whether it was permission, a
pipe, or size — which `look.readFile` only started distinguishing this week.
Known and left: N selections that all resolve to nothing run N searches over
one +Search buffer. Wasteful, converges, and worth its own change.

Every argv refusal in main.zig was `return error.BadArgs` out of `main`, which
std prints as `error: BadArgs` with a return trace under it — the same shape a
real crash has, for the most ordinary thing a person can do. It also said
`BadArgs` and nothing about which argument, at sites that knew exactly:
pardes: no such option: --hepl
pardes: -n takes 1 or 3, not 'abc'
pardes: one file or directory at a time, and 'b' is the second
pardes: --detach and --attach are opposites: one runs the session, the
other joins one
Try 'pardes --help'.
stderr rather than the `+Errors` pane one function down, because argv is read
before a core exists and the person who mistyped a flag is looking at the
prompt they typed it into. `--attach`'s refusal already answered this way; now
all eleven do. `getcwd` failing is no longer reported as an argument problem,
and a `.url` or `@pN` positional says why a LAUNCH cannot act on it rather
than being swept into the same word as a typo.
AND `Look` ON A FIFO NO LONGER FREEZES THE EDITOR. `readFile` opened with a
plain blocking `open`, so a named pipe with no writer waited forever — inside
the keystroke that asked, with no frame, no message row and, in the tty shell,
no Ctrl-C either, because the terminal is in raw mode. It is `O_NONBLOCK` now,
the read loops answer `EAGAIN` rather than waiting, and `lseek` answering
ESPIPE — a pipe, a socket, a terminal — is refused as `NotAFile`, which the
boot pane spells "that is a pipe or a device, not a document". Without that
last part an unwritten FIFO read as EOF and opened a silent empty pane, which
says less than the hang did. The zero-size files worth streaming (procfs and
its kin) seek fine and are untouched.
