Five flows asked two or more things in a row as a straight run of awaits, so Esc
anywhere in one abandoned the lot. Mistype the second half of a 32-hex channel
key and the name you typed first went with it; back out of the courier's
schedule and the message you had just written was gone.
menus.run_steps runs a chain as the stack it is. Each step is awaited with the
answers gathered so far — the same list every time, so a step can label itself
with an earlier answer and offer its own previous answer as its default when it
is come back to — and returns None to step back. None from the first step ends
the flow; there is nothing behind it.
Converted: joining a channel by key and editing one (name then key), the custom
firmware variable (name then value), and the courier's queue flow (recipient,
message, schedule). The courier's recipient list now stays pushed for the whole
flow, so stepping back from the message lands on the row it was being written
to, and the schedule's "At a time…" prompt steps back to its own rungs rather
than out of the queueing.
A step signals "back" with None, which is what _pick_schedule returns for the
real answer "when it's next heard" — so _schedule_step swaps the two, carrying
that answer as its own WHEN_HEARD sentinel.
A trailing Cancel/verb confirm is left alone: its left button says Cancel and
means "don't do this", which is a decision rather than a step. That line is now
in CLAUDE.md with the rule.

Four screens carry a find-as-you-type filter and Esc meant two things across
them: the map and the mesh walk cleared the query and stayed, while the select
list and the path composer left the screen, filter and all. Typing "yul" on the
map then pressing Esc showed you the map; typing "yul" on a contact list then
pressing Esc dropped you at the main menu. Same affordance, same glyphs,
opposite outcome — and the select list is by far the most-used of the four.
They peel now, all of them: the typed query is the most recent thing the reader
entered, so the first Esc takes it back and the second leaves. The footer says
which, swapping its trailing Esc verb for "Esc clear" while a filter stands —
the word the map and the walk have always used, via a _esc_verb helper beside
the two atom-splicers that already bend that line. The composer's Esc now
layers exactly as its own backspace does: the entry first, then the screen.
This was finding D in docs/survey-navigation.md, open since the survey was
written and the last thing left telling a reader what Esc does. The rule is now
stated in CLAUDE.md under Navigation.

The channel detail was the app's last screen rebuilt per round: a fresh
SelectScreen each time, with the cursor restored by default=cursor and anything
typed to filter dropped. It stays pushed now, and its rows and vital-signs line
are swapped in place after each action — both are live (the mute row is a
toggle, the summary counts unread and ages the last message), so both are
re-read, and the highlight follows the row that was just used.
replace_items gains a prompt= so a summary line above the rows can be refreshed
the same way the title already could; without it, keeping the screen would have
frozen the vital signs at whatever they said on the way in.
That leaves _menu_round with no session path at all — both callers now reach it
only when there is no screen stack — so it shrinks to what it always was
underneath: select once, dispatch, be called again. The push/await/pop loop and
the asyncio import go with it.

Backing out of a thread already landed on the picker rather than the menu, but
on a brand-new one: the tool re-ran the whole picker each round and put the
cursor back with a default= restore, which recovers the cursor alone and only
while the row it names still exists. Anything typed to narrow the list was gone
every time, and the screen was rebuilt around two devstate reads.
The picker moves into the tool's own loop and stays pushed, so a chat nests
above it and Esc is one pop onto the row it was opened from — filter, scroll and
all. The row builder splits out as _picker_items, and the rows are swapped in
place after every chat and every delete: an exchange moves its thread up the
recency order and a deleted history hollows its dot and demotes the row, so the
list has to be re-read, and replace_items follows the highlighted thread there.
The picker tests now read _picker_items directly rather than intercepting a
select() call, and the two Del tests drive _delete_history and assert the
rebuilt row demotes — the same coverage, one layer down from the loop.

The same defect Trace had, doubled: both entry pickers were gathered in
prompt_params, so both had popped before the sweep screen opened. Esc from the
sweep landed on the main menu, and Esc from the "measure at" list did too —
never on the node list one step behind it. Tuning a second target meant
reopening the tool and re-picking the node.
Both pickers stay pushed now, one inside the other: admin_node_visit keeps the
node list (the stay form repeater admin already uses), _measure_visit keeps the
target list, and the sweep nests on top. Esc walks the flow back the way it was
entered, each list still holding its cursor, filter and scroll, and sweeping the
same tuned node against a second target is one pick.
_pick_target becomes _target_items, a pure row builder, so the rows and the
screen that shows them are no longer welded together; _sweep resolves a picked
name (or typed hex prefix) and opens the screen. Drops an unused ctx.device()
call — the contacts read ahead of it already needs the link.

The trace-target picker was gathered in prompt_params, which is a one-shot: it
resolved and popped before the live screen opened, so the trace screen sat
directly on the main menu. Esc out of a walk therefore skipped the list it was
launched from entirely, and trying the next node meant reopening the tool from
the menu — the picker's whole recency sort, the typed filter and the row you
were on, thrown away on the way in.
So the picker moves into the tool's own loop and stays pushed for the visit,
the hub idiom the contacts list and the Time Machine already use. The live
screen nests above it: one Esc pops back onto the row that launched it, the
second leaves for the menu. prompt_params now only marks the interactive path.
Coming back re-reads the lanes, because a returning trace ages the very column
the list is sorted by: ContactListScreen.update_rows swaps the rows in place
(the replace_items counterpart for a list whose lanes are data), so the node
just traced rises to the top of the TRACED sort with the highlight riding it
and the filter untouched. Both ages and counts come from stored history, so a
hand-back costs no device round-trip.
The free-text way in — no contacts at all, or no full-screen session — keeps
its one-shot shape, since there is no list underneath to come back to.
test_navigation gains the two guarantees: the picker is still on the stack
while the live screen runs, and update_rows re-sorts without moving the reader.

^Q and ^C exit straight out, and the next reader of that dispatch block would
reasonably wonder whether the missing confirm was an oversight. It isn't: the
quit dialog is there to catch one Esc too many at the main menu, where a single
reflexive keystroke would otherwise end the session (JP, 2026-08-30). A hidden
two-key chord cannot be pressed by accident, so there is nothing for a confirm
to catch — and a confirm is itself a screen that has to paint and take a key,
which is precisely what an escape hatch cannot depend on.
Comment only.

The rules the last three commits established, stated where they bind: a
Navigation section in CLAUDE.md covering the strict stack, `stay`/`Visit` for a
hub, `replace_items` for a list whose content is data, and the modal-vs-floating
distinction ^W turns on.
The two global chords get their one statement on the About page, since neither
has a screen to be advertised on. It also says what happens when the host takes
Ctrl+W first (VS Code's integrated terminal reads it as close editor) — the key
is a convenience, and nothing depends on it.
docs/survey-navigation.md gets its ledger updated: A, B and C are closed, with
what was actually done to each. D and G stay open, and D is now recorded as the
reason Esc Esc was rejected as the pop-all key — on the map, the mesh walk and
chat, Esc Esc is already an ordinary peel-then-leave.
Also drops an asyncio import the watchtower no longer needs, and an escape
sequence in a new docstring that made ast.parse warn.

Six lists rebuilt themselves as a whole new screen every round, because their
content is data: an editor's rows carry a staged `current → new` value, its
title counts what is staged, the outbox loses the message it just sent, the
watchtower's log rewrites the row you acknowledged. Each approximated the cost
with `default=cursor`, which recovers only the cursor, and only while the row it
names still exists — the typed filter went every time.
SelectScreen.replace_items swaps the rows (and optionally the title) in place
instead. The place is kept by value, so the highlight lands back on its row
wherever that row moved to, and falls back to the same position in the list when
the row is gone entirely — which is what you want after deleting the row you
were sitting on. The filter rides along.
So the config editor, device actions, the channel manager, the courier outbox,
the watchtower and the repeater-admin editor all hold one screen for the whole
visit now, refreshed after each action. The courier's ticker is started once for
the visit rather than per round, and folds a flow's effect in immediately rather
than waiting up to a second for the next tick.
The admin node picker gains a `stay` form. Repeater admin used to draw a second,
identical SelectScreen as a static backdrop so the password prompt had something
behind it, then drop the list before the session; the real list stays up through
both now — so cancelling the password lands back on the node list rather than
bowing out of the flow, and leaving a node's admin session lands there too.
Administering two repeaters in a row is an Esc and a pick.

Node detail, the contacts list and the trophy case were each rebuilt every time
something they opened closed. Node detail was the sharpest: its constructor sets
the tab to Info, so Tab to Routes, pick a route, trace it, come back — and you
were on Info at the top again, two keypresses from the route you were working
through, every single time.
All three now stay pushed for the whole visit. The screen object is what carries
the tab, the cursor, the sort and the filter, so returning is a pop rather than
a rebuild. It also retires the pop-then-re-push-as-a-backdrop dance in three
places: a screen that never left the stack is already the backdrop its dialogs
draw over. Contacts still rebuilds after a purge or a removal, and the trophy
case after the record count moves — the rows they were holding a place in are
gone, which is the one thing worth losing the cursor over.
The two peer hand-offs stop flattening. Trace → trophy case used to resolve the
whole trace screen with a sentinel so it unwound before the trophy case opened;
trophy case → trace ran the trace only after the browser came down and then
returned outright. Both landed the reader on the main menu, both said in their
comments that this was to avoid a stack the user would have to Esc through.
That was a hand-built escape from a stack with no other way out, and ^W is the
real one, so both nest now: Esc goes back one, to the screen that opened it.
The trace screen takes an `open_trophy_case` callback rather than resolving a
sentinel the opener has to interpret, which is also what lets the two screens
open each other — a cycle a strict stack allows on purpose.

Navigation was almost a stack already, and the survey in docs/survey-navigation.md
catalogues where it wasn't. This is the machinery for the strict version, plus
the one shortcut past it.
A screen that owns a loop can now keep itself pushed for the whole visit:
async with session.stay(screen) as visit:
while True:
chosen = await visit.result()
One push, one pop, and the *object* survives its sub-screens — so the cursor,
the sort, the scroll offset and any live filter are simply still there on the
way back, rather than being approximated by a `default=` restore that can only
recover the cursor and only when its row still exists. It also retires the
pop-then-re-push-as-a-backdrop workaround: a screen that never left the stack
already is one.
^W unwinds every frame at once, back to the main menu. It resolves the top
screen with POP_ALL, which each navigation boundary turns into PopToMenu, and
every frame pops itself in a finally on the way out — the same single-pop
discipline applied N times. PopToMenu derives from BaseException so it crosses
the `except Exception` guards that stop a broken tool from taking the menu down;
those must not report an unwind as a tool failure. The flag it sets matters
independently of the future: pressed during a device read there is nothing
armed to carry the sentinel, so the next screen the flow tries to open refuses
to open instead.
It declines to fire over anything modal — an unanswered dialog, a progress bar,
a busy splash — which is what `modal` is for. `floating` is only about being
drawn as a box; a select list floats and is not modal, the busy splash is modal
and does not float.
^Q quits from anywhere. Both chords are deliberately unadvertised: a global verb
has no screen to belong to, so a footer atom or an F-key chip would ride on
every screen, and the lane only has three free slots to begin with. A test
walks every string literal in the package to keep them out of the UI.
Quitting mid-screen used to abandon the coroutine driving the app: the chord
exits the application straight from the key handler, so `run_async` returned
while main() was still parked on a screen, and its finally — which closes the
history and chat runs, stops the services and arms the exit watchdog — never
ran. It is cancelled and awaited now.
The menu is the root: built once, kept for the session, and the one frame that
catches the unwind.

The title is the screen's name now, with no status atoms at all. Everything it
used to carry is already on the screen below it: the breadcrumb trail ends on
the focus, the line under that names the node in colour with its hash and its
ring, and how big the neighbourhood is, is what the canvas and the link list are
for. Set once at construction rather than composed per render, so the top row
holds still while the walk moves.

"Mesh walk — YUL-Cartierville · 42 nodes · 61 links · 3 matches" ran 62 cells,
which a 53-column title bar clips rather than wraps — the link count went, and
so did the bar's clip arrows and its Esc hint. The focus was the longest atom,
the one that rewrote the top row at every step of the walk, and the only
redundant one: the breadcrumb trail ends on it and the line under that names it
in colour, with its hash, its ring and when it was last heard.
So the title reads like the map's — the other spatial screen, whose centre is
likewise the body's to name — status atoms only, and the match count swaps for
the node count instead of joining it, the same way the map's does:
Mesh walk · 42 nodes · 61 links
Mesh walk · 3 of 42 match · 61 links

This platform has no footer hint line — the F-key lane stands where it would be,
and the lane only advertises what its five slots do — so Esc, the key every
screen answers to and the reason no screen spends a row on a Back item, was
nowhere on the screen.
It now rides the title bar's tail, last, after the clip arrows and in the same
"↑↓ · hint" shape a floating dialog's subtitle already uses. The verb is the
screen's own: the atom is lifted off its footer hint (the grammar puts Esc last,
so the tail of the hint is the clause), which is how a value picker says keep and
the main menu says quit, and a screen naming no way out advertises none. It gives
way before it crowds the title — the verb first, then the key, then the cells
back.

A picked row folds its node hues to the cursor white so the row reads as one
thing rather than as a name arguing with its own selection. On a path line that
is wrong: there the hue is not decoration on a name, it is what tells one hop
from the next — and what a route graph above the row is cross-referenced by,
its labels being a marker and one byte of hash. Chips were never folded (their
fills are outside the fold's vocabulary), so the bug was the arrow form: every
path line on the PicoCalc, and on any terminal without the powerline glyphs.
PathLine now stamps every shape it mints with PATH_INK, a style that draws
nothing; Text.append_text carries the stamp into the row as a span over the
hops, and the fold skips identity spans lying inside one. So the Message paths
row keeps each hop in the colour its graph label wears, and so do the TX
screen's "Route — via", the trophy board's walk and the feed's sender → recipient
lane. The node detail's Routes tab, which bought this by hand (no cursor base at
all), is untouched.

The skeleton card floated between screens carried a Knight-Rider scanning bar
under its caption: eighteen braille lamps, a red head and a persistence-of-vision
trail sweeping back and forth. It drew the eye harder than the words did, on a
card the reader is only ever passing through, so it and its colour ramp are gone
— the one-cell spinner beside the caption is the whole animation, and the card is
two lines.

The list a screen removes from is the union of the device's contact table and
the contacts MeshTerm remembers for it, so an entry can exist only on our side
— or the firmware can drop one since we last read. Removing such a contact hit
ERR_CODE_NOT_FOUND and reported "couldn't remove", leaving a row the reader had
no way to get rid of.
The device layer now raises ContactNotOnDeviceError for that code, the same
class (and the same table lookup) the send path already raises. The single
removal reports it as a warning naming what happened, forgets our half and ends
the visit; the purge sweep counts it as purged rather than failed. The
simulator refuses the same way, so the path is walkable under --mock.

The app-wide Back row existed because it duplicated Esc — two of its call
sites said as much in a comment. On both platforms Esc is a labelled key
and every footer hint names it, so the row bought nothing for the blank
separator and line it took out of every screen; on the PicoCalc's 26 rows
that is a row in thirteen.
back_rows() is gone, and with it the four hand-drawn copies: ReorderScreen's
clean-state row, the live feed's pinned foot stop (the cursor now clamps on
the oldest packet), node detail's tail action, and the action-list rows on
the trace and TX-sweep screens.
Kept, because there leaving is a choice rather than an exit — the same rule
that keeps a dialog's Cancel button: exit_rows()' staged pair, where Apply
has no key of its own and ✗ Back names what the other way out costs;
ReorderScreen's dirty-state pair; the two Quit rows, which initiate the
app's terminal action behind a confirm; and the new-record dialog's Close,
which is its default, so dropping it would let a reflex Enter navigate.
With no Back row there is no Back value: the six spellings callers used to
test three at a time (_BACK, "__back__", _CANCEL, two tuple shapes, bare
None) collapse to `is CANCEL` / `is None`. The gallery now asserts the
absence of an exit row on every screen, on both platforms.
Resolves findings E and §10 of docs/survey-navigation.md. Finding D — Esc
peeling a filter on three screens and leaving on two — still stands, and is
now the only thing left telling a user what Esc does.

A ZWJ sequence — 🤷♂️, 👨👩👧, 🏳️🌈 — is a single grapheme the terminal draws
in the width of its base, and Rich's stock measurement already knows that.
prompt_toolkit's does not: it adds the codepoints up, reserving three cells for
the shrug and six for the family, and it is prompt_toolkit that places the right
border. Every joined emoji has been pulling a row's border in by the excess.
Correct it in both authorities the same way, by dropping what the joiner folds
in before measuring, so a sequence inherits whatever its base is worth and the
two curated sets still reach it. Rich needed this too: the selector-skipping
replacement was losing the stock loop's own ZWJ handling and counting the male
sign as a cell.
Measuring is only half of it — prompt_toolkit lays out one codepoint at a time,
so the sequence has to arrive as one fragment or it is still laid out in pieces.
ClusterTextControl merges the run on the finished lines (the last point they are
still ours: split_lines returns plain str and drops the marking), and the window
makes one two-cell Char of it. Every codepoint still reaches the terminal, in
order, so the glyph composes exactly as before.
The rule holds at either emoji width, so the width-2 path installs it alone —
no narrowing, no flag category, Rich untouched.

Two comments claimed the pick was channels-only, one of them flatly stating that
direct threads never select. Neither is true: _move_selection and _select_section
carry no is_channel gate, and footer_hint has offered a picked-message hint for
both kinds all along. What actually differs is what Enter does with the pick — a
reply @mention in a channel, the delivery paths in a direct thread.
Both also called it the "reply target", which names only the channel half of
that; it is the picked message, and only one kind replies to it.

An unpainted cell exports as 0x00, which no terminal draws as nothing — it
comes out as tofu, as a stray glyph, or swallowed with the rest of the row
shifted left. One byte wide to fix, and this makes that one substitution and
no other: same length out, every escape sequence where it was.
The trap it exists to avoid is the obvious version of the job. An ANSI file's
last 128 bytes are a SAUCE record whose NULs are structure — binary fields and
the padding on the font name — so a tr over the whole file corrupts the
metadata and fixes no art at all. It cuts at the 0x1A that opens the record and
counts what it left alone. Both splashes are in exactly that state today: 24
NULs each, all of them SAUCE.
A space is only black if the span it lands in left the background black, so
the ones that would come out coloured are named by row and column rather than
quietly repainted — that is an editing call, not a substitution.

The list could only sweep contacts by age — a purge or nothing. Removing one
named contact now lives where the reader is already looking at it: the last
action on its Node detail page, behind a red Cancel/Remove confirm, and the
list it returns to rebuilds without the row.
The deletion lands in both halves of what the list shows — the device's table
and the cross-session store — because forgetting only the radio's half merges
the contact straight back on the next read. A refusal is put in a dialog and
nothing is forgotten: a contact the radio still holds must not vanish from the
list. Only the contact goes; its reception history and chat messages stay, and
a later send offers to write it back.
An action row's tint now survives the icon lane being dropped — it lands on the
label, as marked_label already does for menu rows — so the delete still reads
as a delete on the PicoCalc.

Every framed box was post-processed on the way to the screen: the top-left
corner blended toward white and the highlight decayed along the top and left
edges, so a box read as lit from that corner. It reads as a gradient laid over
the chrome rather than as the box being a box. The borders draw flat now.
The pass goes with it — ui/tui/glow.py, and the three composers that ran it
(base, startup, dialog), each of which also carried the platform gate that kept
it off the 16-slot console where it could only ever hand back the same lines.
Nothing else called it, and its memo went with the module. Text colour is
untouched: the pass only ever recoloured box-drawing glyphs, and titles and
subtitles were already skipped.
The four glow tests become one that pins the outcome instead of the mechanism —
every box glyph in a composed frame, nested panels and dialogs included, carries
the border's own colour and no other. Verified against the old pass: with it
back, that set holds sixty-five.
Platform.effects keeps its other two claims (the header blink, the braille
spinner); it just no longer mentions a pass that no longer exists.

The two marks sat beside the written pages in assets/ under names that spelled
their widths differently and only by accident — logo.ans and logo_53.ans, where
the first is 71 columns and says so nowhere. They move into assets/splash/ as
logo.71.ans and logo.53.ans: one file per canvas, each named for the canvas.
So the size ladder is now the folder listing. _variants() reads the widths out
of the names and walks them widest-first, which means a new size is a file
dropped in rather than a file dropped in *and* a tuple edited. The name only
orders the ladder — which mark fits is still settled by measuring the art, so a
name that overstates its canvas can't draw a torn mark. A test keeps the two
honest with each other: every mark is as wide as its name says.
The old 8.3 spelling goes with the rename. It was there for art editors that
predate long filenames, which manage a second dot fine, and a name that states
its width is worth more than a name DOS could have opened.

Sending to a contact the firmware no longer holds came back as
`send failed: failed to send message to 'bob_caribou': {'error_code': 2,
'code_string': 'ERR_CODE_NOT_FOUND'}` — a wire constant in a status line, and
no hint of what to do about it.
It is reachable for a contact MeshTerm itself listed. The list a screen sees is
the union of the device's live table and the contacts MeshTerm remembers for
that device (core/contact_store), which exists so a RAM-only radio bridge still
shows the nodes you know. The store claims those stay messageable without
writing anything back — true for the bridge, false for a firmware companion,
which addresses a direct message by looking the recipient up in its *own* table
by a key prefix and refuses when nothing matches. So a contact the firmware has
dropped still lists, still opens a chat, and only the send finds out it is gone.
Now the rejection is its own class carrying the contact, and the chat offers the
one write that fixes it: "bob_caribou isn't in this device's contacts, so the
radio can't address it. Add it back and send?" — Cancel or Add & send, then the
same send runs again. Declining reports the refusal in words. The write is
offered rather than silent because it changes what the device stores, and a full
contact table refuses it, which is worth seeing. Retry (^R) takes the same path.
Adding a contact is new to the Device contract (the inverse of remove_contact,
ADD_UPDATE_CONTACT on the wire): the record carries the key, name, type and last
advertised position we already hold, with no learned route, so the first message
floods exactly as it would for a freshly-heard node. The name is clipped to the
32 *bytes* the firmware field holds, not 32 characters.
Every other rejection now reads as a sentence too — reject_reason maps the six
error codes to plain words, so a send, an admin command, or any _ok()'d command
says "the device's table is full" rather than printing its payload dict. The
simulator refuses a recipient it doesn't hold, exactly as hardware does, so the
whole offer is walkable under --mock.

The block was laid out at its full height and whatever overran the screen was
cut off the bottom — which is the box: the device list, the PIN prompt, the
thing the user opened the app to use. The mark kept every row it had.
So a terminal too short for all of it now gives rows back, cheapest first: the
blank line under the mark, which is breathing room and nothing else, and then
the top of the mark itself, up to nine rows of it. Nine is the globe standing
over the lettering — decoration, where the lettering is what says whose splash
this is. Cropping from the top means the lettering and its copyright hold their
place while the mark thins above them, rather than the whole block sliding.
The bound is the art's own height too, so a mark drawn without a globe is never
sheared into its letters, and past the bound the old clip still applies.

On the PicoCalc a repaint costs about 154ms, and these two loops waited 60ms
(the overlay) and 120ms (the splash) between them — rates hardcoded past
spinner_interval(), which every other animated wait in the app already sleeps
on. The animation asked for repaints faster than the console could finish them,
so it took the event loop from the device read it was covering for: the wait got
slower for being animated, and the spinner stuttered anyway. Both defer to the
platform now (0.5s there, 0.12s on the desktop).
Two calls were also blocking the loop outright, which stops the animation dead
however it is paced. Enumerating serial ports is a SetupAPI/sysfs walk — behind
the "Scanning for companion devices…" splash, and again on every poll of the
reconnect dialog — so both go to a thread. The UI itself cannot: prompt_toolkit
owns the loop for render and keys. Moving the blocking work off it is the same
fix from the other side.
Two tests: neither busy screen may carry a spin rate of its own, and the
spinner advances *during* an awaited read rather than only side of it.
Also drops the "· experimental" tag from the network-device row.

The mark's art signs itself now, so no splash adds a line under it — the
picker, the smoke-test spinner, the PIN prompt, the failure notices, the
scan and the settings offer all drop the footnote they were passing, and
nothing draws the notice twice. The written About pages keep their {copyright}
colophon: that is a page of prose, not a screen with the mark on it.
Moebius spells an untouched cell as a NUL, which a DOS console draws blank and
Rich measures as nothing at all — so every one swallowed a column and slid the
rest of its row leftwards, eighteen of them on the worst line. They are spaces
in the file now, and the loader translates any that come back (with codepage
437's hard space) so re-exporting the art can't reintroduce the drift.
Those NULs were also the only reason git guessed the file was binary. With them
gone, .gitattributes has to say so outright, before core.autocrlf starts
rewriting CRLFs that are part of the canvas.

The extension is .ans now, not .ansi — the software that draws this stuff is
old and particular about 8.3 names, and .ans is what it expects to open.
The wide mark is a real ANSI-art export rather than something colour-logo.py
painted, which brings two DOS habits the loader had never met. Its blocks and
box-drawing are single bytes in codepage 437, so reading it as UTF-8 raised
instead of drawing; we try UTF-8 first and fall back, and the 53-column mark
keeps its own encoding either way. And an art editor drops the line break on a
row that fills the canvas, trusting the terminal to wrap it — so the file has
nine newlines for sixteen rows. The canvas width comes from the SAUCE record,
which is trimmed off in the same breath, being metadata and not art.
Re-breaking a wrapped row has to restate the colour across the seam: each row
becomes its own Text.from_ansi, so nothing carries state the way a terminal
does when it never stopped reading the one stream.

The repeater-admin picker drew every name in the repeater violet, so a section of them
read as one node repeated — the one list in the app where telling two repeaters apart is
the whole point, and the only one that refused to.
Nothing regressed it; it was built that way. The row was `Text(glyph, style=type_style)`
with the name appended after, and a style on the Text *is* the row's base — Rich lays it
under every span, so the type colour that should have coloured one mark coloured the whole
line. The name never carried a style of its own to argue with it. The TX-optimize "measure
at" picker was the same row, copied.
So both build the row the way every other list of nodes does: the glyph takes its type
style as a span and the name takes `name_style(name, key)`, hued by the node's key like a
contact row, a watchlist row, a relay hop. That also puts the row back inside the selection
language — with no base style of its own, the cursor row's `cursor` white now reaches the
name span and folds it, which a type-styled base was quietly blocking.

Remote administration still failed. My last two commits classified the failure correctly
and fixed the credential policy, but the login itself kept coming back as no reply from
repeaters that were up, traced, and holding the right password.
The wait I added was counted from the wrong moment. `budget` is the *node's* answer window,
but the clock started before `send_login_sync`, and almost none of what that call spends is
the node's: it first waits its turn on meshcore's mesh-request lock — which every telemetry
poll, status read and courier retry holds for a whole round trip — and only then blocks
until a MSG_SENT the library correlates by event type alone arrives. Whatever that came to
was subtracted from the repeater's window, so the fix read as "wait longer" and behaved as
"wait the same ten seconds, minus the queue". A send that outlasted the budget left the node
no window at all, and the log bears the shape out: both attempts to YUL-UpperSalaberry ended
at 9985 ms and 10015 ms — the budget exactly, spent from before the request was on the air.
So the answer is timed from the send, the way `run_trace` times its reply. And the route
sizing is a floor rather than a verdict: a login is an admin exchange out and back, not a
trace's single small packet, so a contact we hold a one-hop route for was being given a
narrower window (7.2 s) than the routeless contact beside it that floods (10 s). Knowing
where a node is must not make us give up on it sooner.
The rest is making the next failure readable, because this one was not. A no-reply has three
causes that the old line could not tell apart, so it now reports where the time went — the
send's own duration, the budget, and how long the node had — and quotes the frames it heard
but could not act on: a LOGIN_SUCCESS/LOGIN_FAILED naming some other node (a key prefix that
did not match, not a quiet node), and a companion ERROR, which is the one failure that never
reaches the mesh and which `send_login_sync` erases into the same bare `None`. Uncorrelated,
so it is evidence in the log and never a verdict.

A repeater that is up, with the right password, was answering "no reply". My last commit
did not cause that — it renamed it. The failure was already there, mislabelled as a wrong
password (and clearing the credential on its way past, which is how it got reported in
the first place).
`send_login_sync` does not start listening until its own send returns, and that send
blocks until a MSG_SENT arrives — which the library correlates by nothing but its event
type. So a scheduled advert, a telemetry poll or the courier can consume ours and leave
the send sitting on its 15-second default, and every answer that lands during the stall
is dispatched to no listener and dropped. The login the repeater accepted is recorded as
silence. The mirror case is as bad: catching another command's MSG_SENT takes its
`suggested_timeout` with it, and a neighbour's second or two is nowhere near a multi-hop
repeater's round trip.
`run_trace` already documents this exact trap and already solves it, so the login now
does what a trace does: subscribe to LOGIN_SUCCESS *and* LOGIN_FAILED before transmitting,
and keep listening across the whole exchange. `send_login_sync` still transmits — it is
the supported path, and its own listener is harmless, the dispatcher delivers to every
matching subscription — but ours is armed first and outlives it. When it gives up early
we keep waiting for the rest of a budget sized to the route: a login walks out along the
contact's hops and back, which is the shape `trace_timeout` already describes, so the
wire carries twice the stored one-way route. A contact we hold no route for floods, and
takes the flood budget.
The classification falls out of that — the two real frames now reach us, so ACCEPTED and
REFUSED are read off the frame instead of inferred from a `None`. The outcome is logged
at debug (budget, verdict, elapsed) so the next "no reply" is diagnosable from the JSONL
rather than by argument.

Administering a repeater that happened to be down made MeshTerm forget its admin
password. The node had said nothing at all, and we took the silence as a denial.
`admin_login` returned a bool, and all five callers read `False` as *wrong password* and
dropped the credential. Underneath, they could not have done better: meshcore's
`send_login_sync` waits for LOGIN_SUCCESS and only LOGIN_SUCCESS, so a refusal — which
the firmware does send, as a LOGIN_FAILED frame the library parses and dispatches like
any other event — times out exactly like an unreachable node and comes back as the same
`None`. Our own `etype in (ERROR, LOGIN_FAILED)` branch could never fire.
So the device now watches for that frame itself, subscribed before the request goes out
because the refusal can land the moment the request does, and answers with a three-way
`LoginResult`: ACCEPTED, REFUSED (the node said no), NO_REPLY (nothing came back — which
includes a companion-side error, where the request never even left the radio). It is
truthy only when logged in, so `if not await device.admin_login(...)` still reads "we are
not in"; a caller that acts on the failure has to name which failure.
What that means for the stored password now lives in one place, `AdminStore.record`:
remember on accepted, forget on refused, leave it exactly as it is on silence. It was
five copies of the policy, and every copy was wrong the same way. Each surface still
phrases its own message — the sweep says "sweep again", the CLI says "re-run" — and a
no-reply now says so plainly ("No reply from X — it may be out of reach, asleep, or busy.
The saved password was kept") instead of accusing the operator of a typo. The trace
screen's forget-on-DeviceAuthenticationError goes with it: the credential is settled
where the outcome is known, and an exception there is only a message to show.
A source-level test walks the package's AST and holds the line: anything that calls
`admin_login` records the outcome through the store, and nothing reaches for `forget()`
to decide this on its own.

Teal was still answering three questions it had no business answering. The wordmark's
colour is the app's identity, and it is also a node hue — so a cyan-keyed node could
vanish into the very highlight pointing at it.
- A node's key-derived hue folds to the cursor white on the cursor row. A row is a
column of identities right up until it is the row you are on, and then it is
answering a different question; a hue on it argues with its own selection. Folded
once at the render boundary for any Text whose *base* style is `cursor` (which is how
every list and every screen drawing its own rows already marks it), so no screen has
to remember the rule. `theme.is_identity_style` is node_style read backwards — every
hue a key can mint, on both platforms — and only those fold: the heat of an age, an
SNR reading, a red badge, a path line's chip fills all keep what they were given. So
does the grey of a node no key could place: the highlight knows where you are, not who.
- The reverse-video chip — a dialog's committing button, a running action's Abort, the
arrow-mode composer slot, the editor cursor — is grey. A chip marks where a press
lands. It is chrome, and chrome does not get a hue. Light grey slot 7 on the VT: the
one grey a reverse can put behind text there, and the fill the F-key lane already uses.
- The active sort column's heading and triangle take the same white as the cursor row,
being the same claim one axis over. They were a bare `#22d3ee`, which put a selection
cue back on the node spectrum and, on the console, straight onto the brand's own slot.

Restoring a backup onto a freshly flashed companion put the identity and
the channels back, reported all eighteen operations applied, and left the
node advertising from latitude 0.0 on the factory frequency.
Latitude and longitude reach the firmware through one command, and so do
the four radio parameters, so changing one means re-sending its siblings
unchanged. Those siblings are read from the caller's snapshot — taken
once, before the first write. Applying adv_lat preserved the stale
longitude; applying adv_lon then preserved the stale *latitude*, undoing
the first write. Same shape for radio_freq followed by radio_sf. Nothing
errored: each op did exactly what it was told, with a picture of the
device that was two writes out of date.
So each coupled applier now records what it set. Any later sibling in the
same batch preserves the new value rather than the one that was true
before the batch began — whether the batch comes from config restore or
from the editor's staged changes, which had the same hole.
And the Device PIN row, found while writing the restore instructions: it
read 'device_pin' out of a snapshot that only ever held SELF_INFO, while
real firmware reports the code as 'ble_pin' in the device-query frame. It
could therefore only ever render "?" on hardware — writable, with no way
to see what you wrote, so a typo sat in NVS until the next pairing. The
snapshot now folds in that frame (SELF_INFO still wins where they
overlap, as probe_device already had it), the row reads the firmware's
own name while keeping the key its backups and CLI use, and the simulator
reports it the same way so --mock shows the same screen.
Verified on the reflashed device: the row reads 701307, and model and
firmware version arrive with it.

Owning the meshcore client was necessary but not sufficient, and the
device said so: the same probe still went off the air.
ConnectionManager.disconnect closes its transport only if _is_connected,
a flag it sets *after* connection.connect() returns. The GATT auth error
is thrown from start_notify, long after bleak brought the link up and
well before the manager records anything — so the manager is certain
there is nothing to close while BLEConnection is still holding a live,
connected BleakClient. Calling mc.disconnect() and stopping there looks
exactly like a teardown and leaks the link anyway.
So _discard_meshcore now runs both halves: the graceful call, which stops
the dispatcher and cancels any reconnect task, then the transport closed
directly, which is what actually drops the link. BLEConnection.disconnect
re-checks client.is_connected, so the second close is a no-op whenever the
first one sufficed. That forced path already existed inside disconnect()
for the dispatcher's queue.join() deadlock; it is factored out as
_force_close_transport and shared, so the two teardowns cannot drift.
The tests grow a fake that models the manager's guard rather than counting
disconnect() calls, so they assert the link went down instead of asserting
a method was invoked — the distinction the first attempt failed on. A
test named for that mistake pins it; reverting to graceful-only fails
seven of the ten.
Verified on hardware, instrumented: the auth path now shows
is_connected True -> False inside the discard, the client ends at None,
and the peripheral keeps advertising. Full lifecycle clean in one session
with no power-cycle — PIN-less probe, PIN retry, bonded session with real
traffic, mid-session bond query, Unpair & quit, and a relaunch after it.

MeshCore.create_ble builds its client, calls connect() on it, and hands
it back only on success. A connect that *raises* therefore left that
client — and the bleak link it had already opened — orphaned inside the
library with no reference we could close. Our _mc was never assigned, so
disconnect() was a no-op and the probe's _safe_disconnect closed nothing.
That is not a corner: a PIN-protected companion answers the unbonded
notify-subscribe with a GATT authentication error, and the picker's first
attempt is always PIN-less. So selecting an unbonded companion leaked the
link, Windows held it for the life of the process, and the peripheral —
still believing it had a peer — stopped advertising. The PIN dialog then
asked for a code it could no longer deliver: the retry paired at the OS
level (the bond really is created) but could not form a GATT session, and
the user was told their correct PIN belonged to something that "isn't a
MeshCore companion". Since Unpair & quit is what leaves you unbonded, the
whole thing read as unpairing having changed the PIN.
Assemble the two objects here instead. _connect_owned_ble keeps the
handle, so both failure shapes close it: a raise (closed, then re-raised)
and a None handshake (closed, then reported as "not a companion"). The
teardown is shielded — the other way in is a probe whose wait_for expired
and cancelled the handshake, where a plain await would be cancelled the
moment it suspended and abandon the very close it was called to perform.
The picker's accepted PIN now also rides on the context, so a mid-session
reconnect doesn't re-run the whole "needs a PIN" dance against a companion
we already authenticated to. Session-lifetime only; nothing reaches disk.
Tests stop naming a real companion: the addresses and pairing code are
stand-ins now, and the fakes model the class we construct rather than the
create_ble we no longer call.

The row `❯` points at borrowed `brand` — so the app's identity ink and
"the row you're on" were the same hue, and worse, teal/cyan is itself a
node hue: a cyan-keyed node's name vanished into its own highlight.
Give the highlight its own name. `cursor` is white on both platforms
(slot 15 on the VT, the top of the bright bank, so the row's bold cannot
promote it further and every dim-slot `not bold` pin inside a highlighted
row goes on meaning what it meant). White sits outside the per-node
spectrum, so it can never collide with an identity; it does share ink
with `you`, which is the accepted cost — spans that set their own colour
keep it over the base, so only unstyled text goes white, and only on the
row already under the reader's eye.
Every surface that draws its own cursor row follows: the select list and
its reorder mode, the feed, chat, routes and actions on the node page,
the composer, records, trace, tx, the walk, the paths screen, the prompt's
suggestions. The composer's insertion-slot chip takes the same white — its
docstring already tied it to "the colour the list cursor below it wears",
and the chip ink was already picked to stay readable on white.
Reverse-video chips keep `selected`: on the VT a reversed white lands on
the light grey the F-key lane already owns, so a white default button
would stop reading as the committing verb.

Emptying a trace's relay path — right, since those bytes were readings all
along — left the card contradicting itself: three legs on the links row,
"direct — no relays" two lines under it, and a note crediting the reading
to a sender nothing had relayed for.
An empty chain means different things by class. For every other frame it
means the sender was heard straight off the air. For a trace it means the
relays went unrecorded, which is not the same claim at all — the readings
are proof something forwarded it. So the row says how far the packet got,
which is the one thing those readings do establish, and the reception note
goes back to naming the last relay.
Both are catalogues, not changes. Nothing in either has been acted on;
each finding says where it is, what it does, and what makes it a question,
so the decisions can be taken one at a time instead of discovered one at
a time. Every code reference in both was machine-checked (144 of them).
The navigation survey lists every place the app does something other than
"Esc pops and you carry on". The headline is that three screens rebuild
themselves each round and lose your place — node detail loses the open tab
too, so working through the Routes list means re-opening it after every
trace — while eight others carefully restore it and four sidestep the
problem entirely by keeping one screen for the whole visit. Also: Esc
peels a live filter on three screens and abandons the whole screen on two,
which is the same keys giving opposite results on the app's most-used
list; six different spellings of the value a Back row resolves with, so
callers test three at once; and a pop-then-re-push workaround repeated
five times where the session API has a gap.
The consistency survey is mostly good news — footer hints, titles, the
lexicon, status marks and the query line all came back clean under
mechanical sweeps, which is what makes the nine remaining items worth
trusting as close to the whole list. The ones that show: four screens
whose empty state shouts in sentence case when the empty state is the only
thing on screen, a dialog with no Cancel whose default lands on an action
and whose rightmost button is the destructive one, and two full screens —
Trace among them — that never had a PicoCalc lane pass and so advertise
pager chips that do nothing.
The row's whole implementation was `super().handle("escape")` — Esc, spelled
out as a cursor stop. It cost a keypress on every platform (End then Enter,
against one Esc), sat below the row that commits so End landed on the way
out rather than on the thing you came to do, and taught nothing: Esc leaves
every other screen in the app without being told to.
The action group now ends where the actions do — Use this path, then Auto
in target mode. Cancel stays where it earns its place: a dialog asking a
real question, where the choice is the point.
A trace reports on the mesh as it crosses it — every node that forwards
one records the SNR it heard its predecessor at — so an overheard trace
arrives carrying a reading per hop travelled. Those are now a `links` row,
in walk order and coloured by quality like every other reception figure,
which for a walk out and back through a repeater reads as one strong
outbound leg and two weaker ones home.
The card's standing caveat also stopped being true. "Reception describes
the last relay, not the origin" is right for a relayed frame and wrong for
one that crossed nothing — those are only listed at all as of this
branch — where the reading *is* the origin's, and worth saying so: a frame
heard straight off its sender is the best evidence a link ever gives.
The readings a trace collects arrive where every other class keeps its
relay hashes, so `path` was exactly the wrong place to keep them — and
keeping them there fed the topology graph links nobody observed. They get
`observations.trace_snrs` instead, written and read like the crypto trio
and the addressing columns before them, so a replayed frame shows the same
links a live one does rather than a blank lane.
The 1606 rows already stored were migrated in place: 2454 readings
recovered, every one of them at the 1-byte width the wire uses, and every
fabricated path cleared. The pairs read as what they always were — one
trace heard twice, once a hop out (+13.25 dB) and once on the way home
(+13.25, -5.0, -4.25), the return legs weaker exactly as a longer walk
should be.
Two silent drops in the RX-log mapper, and between them a device sitting
beside this one could trace all day and never appear in the feed.
A frame that crossed no relays was discarded as having "no topology
content". It has the most there is: nothing stood between us, so we heard
the transmitter itself. Only an advert survived, and only because it
carries an origin key — every trace, message, request and ack from an
adjacent node went into the bin. Now a frame is kept unless the library
could not even give it a payload class, and the empty path says what it
means: zero hops crossed.
The other is a trace reading its own header wrong. Every class keeps
relay hashes in the path field; a trace keeps one signed SNR byte per hop
it has traversed. Read as hashes those bytes resolved to whichever nodes
shared their leading digits and entered the topology graph as links that
were never observed. The population says so plainly: across 1604 stored
traces, all 2221 path entries land inside the LoRa SNR band when read as
signed bytes, spanning -10.5 to +15.0 dB, where hashes would put five in
six outside it. So a trace now yields no hops, and its readings — which
are worth having — ride alongside as trace_snrs.
The 1604 rows already stored keep their bad paths; a one-shot cleanup
follows separately.
_compose will not place a label under its own min_zoom, and street names
carry one of 15. _draw_tile built them anyway, at every zoom: a named
road's label is the expensive half of it — the line clipped to the canvas
segment by segment, each surviving piece measured, the pieces sorted, and
feature_to_dot called once per vertex, which is the per-vertex function
call the geometry path beside it deliberately inlined away. A central
Montréal tile carries 270 of them.
Measured on the desktop against the committed renderer, one tile at
PicoCalc geometry: 16.8 ms of a 46 ms frame at z13, all of it discarded a
moment later. Below the gate a frame is now 27-52% cheaper across z9-z14,
which on the device is a third of a second off the two zooms the map
most often sits at — it opens on the region fit, and z13/z14 is where a
mesh-sized frame lands.
The zoom is the display zoom, not the tile's: an overzoomed view reads
its ground off a lower tile but is still zoomed in, and still wants its
names. The 15 is a constant now, read by the queue-time gate and the
place-time test both, so the two cannot drift.
Nothing in the picture moves. Rendered against the pre-change renderer at
z9-z18 on three geometries, coarse pass included: every frame
byte-identical, every Ghost raster identical (a label was never in the
raster — that is the overlay). The skipped candidates never reached the
max_labels budget either, since the placement loop continues past an
under-zoom label rather than counting it, and sorted() is stable, so what
does get placed is unchanged. Crossing the gate changes the viewport and
so the ground key, which means a zoom across it always redraws rather
than serving a frame short of its names.

_COARSE_PREVIEW turns off the two-pass draw: every view now waits for the
whole picture, standing on the last frame's ground reprojected until it
lands, or on nothing where the view has run past that too.
None of the machinery goes. Both passes still draw, render_ground still
takes coarse=, and the abandonment point between them is still where a
held pan key gets off — what the switch decides is only whether a moved
view is offered the first pass, which is why it is read where the raster
is asked for and not inside the renderer. Turning it back on is one line.
The abandonment test needed to say what it means to survive the change:
it asserted no finished pass appeared in a list it read after the loop
closed, which quietly depended on the *next* view's draw not getting a
scheduler step in time. It reads the list where the abandoned key's draw
returns now, and asks only about that key.
