A final pass over the docstrings and comments: "the own X of Y" is now
"Y's own X" (84 places), a navigation entry is a screen on the stack, our
node is our node, a paint is a paint, the quoted UX labels are in code
font, and a list of punctuation glyphs is in code font.

The README, CONTRIBUTING, SECURITY, the docs index, the development
documents, the script READMEs, the comments of config.example.toml and
pyproject.toml, and the issue and pull request forms. The legal sections
of the README (attribution and licence) stay exactly as they were, between
ste: off and ste: on markers. The SignPath attribution line, the one-line
description of MeshTerm, every code block, and every URL do not change.

The Python scripts, the packaging code, and the full-line comments of the
shell scripts. Heredocs, marker lines, licence lines, and code do not
change. The help text of type-text.py now starts with a complete STE
sentence, and uart1-mux.py now says three writes, as the code does.

The console font gains the two powerline chevrons, drawn into the next
two donor slots (U+2559 and U+255B, which nothing draws), in both the
6x12 and the 6x8 builds. With them in its inventory, the PicoCalc's
verdict is core, so its routes are ribbons of chips like the
Cardputer's.
A chip there can only be filled from the eight background slots, since
under a 512-glyph font the VT has no bright backgrounds. So a node's
chip is the dim twin of its hue (theme.DIM_TWIN), and its label is the
hue itself: the colour the name has in every list and in arrow mode. A
hash label and an annotation are that colour throughout. A keyless chip
is white on light grey, the same pair one bank down. Our star, a faded
hop and the composer's slot have no dark grey to stand on, so they
stand on the page, the slot as a white + in a break of the ribbon. Two
chips of one colour join on a thin chevron in that colour.
Bold is brightness on the console, and Rich merges a selected row's
bold into every span on it, which turned the dim fills bright. Every
chip style there says "not bold"; the tests read the rendered row back
through the emulator's VT to hold that.
The new font takes effect once the font script runs again on the Lyra
(as root). Until then the PicoCalc's installed font lacks the chevrons.

They were committed from Windows, which records no execute bit, so on
the device `scripts/cardputer-zero/launcher-entry.sh` -- run by path, as
its own usage line and the Cardputer guide say -- was refused with
"Permission denied" while the file sat right there. Every script under
scripts/ that starts with #! is now 100755, as the uConsole bridge
already was.

The launcher entry carried a placeholder. Its icon is now meshterm.net's
logo, the red skyline, resized to the launcher's 100x100 the way the
site makes its own small icons (Lanczos from the 410 px source).

On the device MeshTerm ran, drew every frame, and stayed invisible: the
panel kept the launcher's last frame while a splash nobody could see
waited for a key. The panel is a DRM driver whose /dev/fb0 is fbdev
emulation, and the kernel copies to the glass only what it sees change
through the *mapping*. pwrite() put the pixels in the buffer, where
reading /dev/fb0 back showed them, and never on the panel. The frame
now goes through an mmap, as M5's own LVGL apps write theirs. Checked
on the panel.
Also scripts/cardputer-zero/type-text.py: paste a long string (an API
key, a Wi-Fi password) on another computer and it is typed on the
Cardputer's keyboard over SSH, into whatever app has the screen. Input
is hidden and travels on stdin, never on a command line.

Tried on a real Cardputer Zero for the first time. It draws on the
panel, takes the keyboard, and opens from M5's app launcher:
scripts/cardputer-zero/launcher-entry.sh puts a source checkout there
(and `remove` takes it off) until there is a store package.
Three things the hardware showed:
- The splash opened with the highlight on /dev/ttyS0, the Cap's GPS
UART, because serial is listed first as found. Below the companions
we've used, anything that looks like one now comes before a port
nothing vouches for, across transports.
- The title bar's battery is the handheld's own BQ27220, as the
PicoCalc's is. The host pack is now found by what it is (a Battery
supply that isn't a peripheral's), not by the PicoCalc's name.
- While the Cap is powered, I2C bus 1 turns noisy: a quarter to three
quarters of the gauge's reads fail with an I/O error (one in ten of
the clock's), none with the header off. A failed read is asked again,
a status that won't read keeps its last verdict, and a good reading
stands through six failed polls instead of blinking out.

`meshterm emulate cardputer-zero --mock` and `meshterm emulate picocalc-lyra --mock`
open a desktop window drawing MeshTerm as that device's own screen draws it. An
EmulatedDevice (emulator/devices.py) holds what differs per handheld: the panel, a
Linux console's top-left grid and bold-as-bright 4-bit palette for the PicoCalc, the
lane keys drawn under the Cardputer's panel, and how each keyboard spells Shift with
an F-key (the PicoCalc's F6-F10, the Cardputer's xterm-shifted F4-F8).
It is not a strict emulator, and the docs say so wherever they offer it: MeshTerm runs
on the desktop as itself, and the window mimics the display's and keyboard's
constraints, never the CPU or the OS. Inside it the platform resolves with own_display
(platforms.drawn_by_meshterm), so nothing offers to move to another terminal.
Global options typed anywhere (--mock, --port, --db...) reach the emulated MeshTerm.
The command refuses --json like specimen. The Terminus fetch moved into the package as
`meshterm emulate --fetch-fonts` (with --archive for a copy fetched another way),
replacing scripts/cardputer-zero/fetch-terminus.py. A build without Tk says to install
with pip or pipx instead of failing.

"Host" already meant two things here: a TCP companion's network host,
and battery="host" for this machine itself. And with a PicoCalc preview
coming, the package is less a console host than an emulator of a
handheld's display: its panel, grid, font, colours and keys. So it is
meshterm.emulator, Platform.console_host is own_display, its desktop
window is window.py (EmulatorWindow) and its device front end
framebuffer.py, since "sim" and "device" now mean the radio simulator and
the device being emulated. MESHTERM_HOST_FONTS is MESHTERM_EMULATOR_FONTS.
The package's own description opens on what it is not: nothing runs the
handheld's processor or operating system; it mimics the display's
constraints so the window obeys the device's.

M5Stack makes three Cardputers and only the Zero runs Linux; the PicoCalc
takes several cores and only the Luckfox Lyra runs MeshTerm. So the bare
names were ambiguous, and every reference to the two devices now carries
the variant: the --platform values and MESHTERM_PLATFORM, the Platform
constants (PICOCALC_LYRA, CARDPUTER_ZERO), their lane decks and every
screen's picocalc_lyra_lane / cardputer_zero_lane, the font inventories,
the lane chips' theme styles, the scripts/ folders, the two chrome test
files, and the docs and CLAUDE.md that name them.
There is no alias: --platform picocalc is refused with the three real
choices listed, rather than falling back to the desktop layout. The
PicoCalc is auto-detected from its device tree, so it needs nothing.
What names hardware or a user's data keeps its name: the PicoCalc
keyboard's input-device name, its battery's sysfs supply, and the serial
profile the Lyra setup script writes. .gitignore follows the firmware's
folder, and the changelog keeps the words each release used.

docs/ was one flat folder: the user guides, the CLI manual, the device
manuals, the code notes and an old survey side by side. It is now
guide/ (features, configuration, connecting, terminals), cli/ (the
manual as its README, the cookbook), devices/ (which manual is yours
as its README, then one per device) and development/ (architecture,
the survey); screenshots/ stays put. The index follows the folders.
The device manuals are named for the device they are about: the
PicoCalc's is picocalc-lyra.md, since MeshTerm runs on the PicoCalc's
Luckfox Lyra core and on none of the others, and the uConsole's stays
uconsole.md, since its CM4 and CM5 run it alike. A new cardputer-zero.md
opens on a warning that the device is not supported yet, says what has
been built and tested only in the simulator, and how to try it there.
Every relative link was resolved from where it was written and rewritten
from where it now lives, and the repo-root spellings in code, config and
the release skill moved with them; the changelog's GitHub URLs too.

MeshTerm only ever draws braille as pixels (charts, the map, meters), so
each dot is now a solid tile of its share of the cell: 3x3 at 6x12, 3x2
at 6x8. A run of lit dots reads as one continuous mark instead of a
dotted one. Both fonts take it from the shared generator.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The stock image gives an app no text console, so MeshTerm draws its own: the TUI
runs in-process with prompt_toolkit's output feeding a small VT parser, the cells
are drawn in Terminus 6x12 with MeshTerm's marks over it, and keys go in through a
pipe in xterm's spelling. The front end is the only part that differs: framebuffer
and evdev on the device (written ahead of the hardware), a Tk window on the desktop.
Each handheld's glyph inventory is now named by Platform.font, which replaces
ascii_fold; the render-boundary fold derives its accents, emoji, and fallback from
that inventory and quantizes colour only where truecolor is off.

MeshCore transmits a 32-symbol preamble up to SF8 (16 above), but the
node and the bridge configured the SX1262 for the library's fixed 12.
The chip waits for the sync word only about as long as the preamble it
expects, so it locked onto each packet, gave up, and locked on again
further along the same preamble - decoding a packet only when it
happened to catch the tail. On the uConsole that meant 0 of 5 detected
packets decoded after a send; with 32 symbols, 4 of 4.
The node now derives the preamble from the spreading factor as MeshCore
does, and re-sends it to the listening chip when Device config changes
the SF. preamble_length leaves the SPI wiring table (it was protocol,
never wiring) and is retired; the bridge defaults to the same rule.

A LoRa chip on the host's own SPI bus (the uConsole AIO) is now a
transport like serial, BLE, and TCP: --spi, an SPI profile, or the
picker's row for /dev/spidev1.0. MeshTerm starts a software node as a
child process under whichever Python has openhop-core, talks to it over
a loopback port, and ends it on disconnect; the node also exits with its
parent, so the pins are free whenever MeshTerm is not running.
The node keeps identity, prefs, channels, and contacts under
~/.meshterm/radio/<spidev>/, and on first use copies the bridge's
identity, contacts, and radio settings so it stays the same node.
Board wiring lives in a profile's spi table; radio settings are the
node's own, edited on Device config. Closes#21.

The radio library keeps its channel table in memory only, so every bridge
restart came up with no channels while MeshTerm's own mute settings
survived. Snapshot the table to channels.json after every set or clear,
the way contacts already were, and replay it at startup.

Every manual was read against the code, the scripts and the upstream sources, and the
samples in docs/cli.md were recaptured under --mock where they had drifted.
The one a newcomer would hit first: config.example.toml set default_profile to a COM5
profile. Copied verbatim, as configuration.md says to, it broke every device command on a
machine with no COM5. default_profile is commented out now, so the copied file leaves
discovery working. default_tx_power goes from both, because nothing reads it.
docs/cli.md: config show has 22 settings and preferences show 21, not 20 and 8; monitor's
blocks have no blank line between them; the diagnostics sample is labelled as a real-radio
example with absolute instants and every table; an unknown key exits 1; devices, role and
records describe the values they really produce; no maintainer paths; and the "used to"
passages describe the present, since a first-time reader never saw the past.
picocalc.md: the Calculinux image carries a build stamp, so the gunzip and dd lines take
a wildcard; the front SD slot stays empty on first boot; masking wifi-kick is what stops
it, and time-sync is disabled with it; updates run the scripts from the pulled checkout
with TMPDIR set; the tested list names only what a test checks; git ships in the base
image; a bare meshterm shows the splash, and -p picocalc skips it.
uconsole.md: an AIO v2 needs MESHCORE_EN_PINS=27 whichever runtime is installed; the
bookworm paragraph states what upstream actually ships; the bridge shares the key but
keeps its own contacts and radio settings; the defaults are the US/Canada preset; Step 7
downloads what it installs; updating ends with a restart; no claim of test coverage the
suite does not have.
terminals.md, features.md, hardware.md, cookbook.md, configuration.md and the scripts
READMEs get the smaller corrections their audits found.

The map is the only networked part of MeshTerm, and every failure on that path
is logged at DEBUG while log_level defaults to WARNING: a reader whose tiles
never arrive gets a blank ground and no explanation anywhere. On macOS that is
routinely a Python with no certificate store at all, which no amount of looking
at the app can reveal.
scripts/basemap-doctor.py is the explanation. It reports the interpreter, the
trust store, the tile source and the cached-tile count, then fetches the
TileJSON and one real tile the way BasemapSource does, and turns the failure
into one verdict with its fix.
The verdict is an A/B rather than a reading: curl verifies against the OS trust
store and Python against its own, so curl succeeding where Python fails is the
app's store and nothing else, while both refusing the same certificate is TLS
interception or a genuinely bad server — one exception, opposite causes,
opposite fixes. Collapsing curl's exit codes into "failed" had it blaming the
store and the network in the same breath.
It also answers the other way a map looks wrong, since it costs nothing in the
same round trip: an unset COLORTERM is 256 colours, where the basemap's greens
and blues collide.
Started under the wrong Python it finds the installed meshterm command, reads
its shebang and hands itself over, so nobody has to know which of their three
Pythons the app went into. By subprocess, not execve, which on Windows is not a
real exec and segfaults under a redirect — and stdout is flushed first, or the
banner loses the report it introduces.

The Calculinux bring-up, both console-font builds, the GPL-2.0 text that belongs
beside the 6x8 one, and the xiao-radio firmware kit move under scripts/picocalc/;
the SPI bridge is scripts/uconsole/meshterm-spi-bridge. The folder's own README is
gone: its per-file index is now a section of docs/hardware.md, next to the table

docs/hardware.md shrinks to a router: which guide for which device, and the
two platform flavours. Everything the guides were still reaching into it for
moved home — the bridge's environment knobs into uconsole.md, and the
verified/unverified lists into each manual's closing section, split by
device (the PicoCalc's gains the MX1.25 pin order and the 5 V path, both
inferred rather than measured on a Lyra).
The PicoCalc manual gets the Wi-Fi kick back — it works and stays; only the
join script is going. The uConsole manual opens on the same kind of
disclaimer as the PicoCalc's, minus the hardware-handling parts: a LoRa
transmitter, a Linux shell, the guide may be wrong or stale, your call.

scripts/calculinux-console-font.sh is now calculinux-console-font-6x12.sh.

SHARED default and comments, the theme16 test that parses it, the module
docstrings, the two manuals, the scripts index and CLAUDE.md. The font files
it builds keep their names.

docs/picocalc.md starts from a stock PicoCalc with its Pico and ends with a
Linux handheld running MeshTerm with a LoRa radio soldered inside: a priced
shopping list, the Lyra swap, writing Calculinux, the serial console, Wi-Fi,
the setup script phase by phase, then PlatformIO, the firmware build with the
patch explained hunk by hunk and a by-hand route for when it stops applying,
flashing, the four wires, the Lyra setup, day-to-day use and troubleshooting.
The README gains a Documentation table and points the handheld paragraph at
the two manuals; the script indexes and the changelog follow. hardware.md
stays as the reference behind both.

Apache-2.0 does not require per-file headers, but a file lifted out of the tree carried no marking at all. One comment line, first (or right after a shebang), on every .py under meshterm/, tests/, packaging/ and scripts/, plus the extensionless SPI bridge; tests/test_spdx.py keeps a new file from landing without one.

The GPL-2.0-only 6x8 script executes the generator block out of the Apache-2.0 6x12 script, and GPLv2 and Apache-2.0 do not mix inside one program. Both files are the author's, so the block between the BEGIN/END markers is additionally available under GPL-2.0-only for that use; both headers and the hardware manual say so. No code changes.

meshcore-uart1.patch quotes upstream lines and build-firmware.sh produces a MeshCore binary, so the licence those copies travel under now sits beside them as scripts/xiao-radio/LICENSE.MeshCore, verbatim from upstream, and is named from the bench card and the hardware manual.

pymc_core was renamed openhop_core in 2026 and the current meshcore-uconsole
package depends on the new name, so a bridge that only knew the old one failed
its own preflight on a fresh install. It now finds either runtime, newest first
(an interpreter with openhop_core beats an earlier candidate with pymc_core;
MESHTERM_PYMC_PYTHON still overrides), imports through the name it found, and
lets two of its three compat shims stand down under openhop_core, which accepts
long ACK payloads and pushes completed trace replies itself; pushing a trace
twice was the alternative. The raw RX-log push is still the bridge's.
What the port found on the device shaped the rest. The 1.12.0 .deb is built for
trixie against Python 3.13 and cannot run on a bookworm uConsole, so the bridge
looks first in a venv of its own (~/.local/share/meshterm-spi-bridge/venv, made
with openhop-core[hardware]) and, without the GUI's helpers there, configures
the radio itself with the uConsole AIO preset rather than the runtime's
Waveshare defaults (TX-enable on pin 6, no DIO2 switch, no TCXO -- deaf on the
AIO), every MESHCORE_* knob the GUI reads honoured and passed only where the
constructor accepts it. It also loads the GUI's identity key first, so a bridge
in its own venv is still the same node. Verified on the uConsole: openhop-core
1.1.3, radio up, 159 contacts restored, info and contacts answered over TCP,
and the boot service now runs from that venv. The manual and the index say all
of this instead of the rename warning.

A Linux VT loads one font for the whole console, so asking for the 6x8 build
(53x40, fourteen rows more) changes what the shell is drawn in too. The new
console_font preference (6x12 default, 6x8 the alternative, offered on the
PicoCalc only, round-tripping through preferences.yaml on every platform)
therefore comes with services/consolefont.py: remember the font the shell had
with `setfont -O`, apply the one the preference names, and restore it on every
way out -- the menu's finally and an atexit hook, since ^Q and an unhandled
error leave by other doors. Verified on the device that setfont -O captures
the current font with its unicode table and that feeding it back reproduces it
exactly, with no sudo, because the VT is the process's own controlling
terminal. Only the interactive menu switches; a scripted run never touches the
console it was invited into. Changing the preference on its page applies live.
Shipping both fonts needed the licence untangled: the 6x8 base is the Linux
kernel's font_6x8 bitmap, GPL-2.0, so its build moves into
calculinux-console-font-6x8.sh under that licence with the GPLv2 text beside it
in scripts/LICENSE.GPL-2.0. The shared generator stays in the 6x12 script
between BEGIN/END markers and the 6x8 script executes that block, so the marks,
donors and aliases the font contract pins exist in one place. The produced PSF
is a data file the kernel console reads; MeshTerm never links or bundles it, and
NOTICE and the hardware manual say so. PrefSpec gains a platforms gate for the
page; the labels use an ASCII x because U+00D7 is not in the console font.
The 6x8 base has no Cyrillic; the manual says so and the owner accepts it.

docs/hardware.md is the single place a reader goes to put MeshTerm on a
PicoCalc or a uConsole, written in the shape of the command-line manual: what
the three targets are and which exclude each other, why the console font is
built on the device, every phase of the Calculinux bring-up and its knobs, the
XIAO UART radio from parts to a verified link, the SPI bridge with an honest
note that it was written against pymc_core 1.0.x while today's uConsole stack
depends on the renamed openhop-core, and a closing list of what has only ever
been proven on one bench. scripts/README.md and xiao-radio/README.md become
short indexes pointing at it; the old ones were stale in four places (trace
through the bridge works, the firmware env is _serial, two scripts were
unlisted). README links the manual, gains the two dependency rows it lacked
(markdown-it-py, PyYAML) and a fixed fonts anchor.

A read-through of scripts/ ahead of the public release, applying only what could
be verified from the code. The setup script clones over public HTTPS when no
deploy key sits at KEY_PATH and keeps the SSH path when one does, and its
timezone is a TIMEZONE knob rather than a hardcoded city. The flasher recognises
the plain XIAO nRF52840's bootloader (PID 0x0044) as well as the Sense's
(0x0045), both from Adafruit's board.h. The mux unit was After= the very target
that WantedBy= pulls it into, an ordering cycle; it now orders on basic.target,
which still wants a check on the device. The console-font header stopped
claiming a default run installs /etc/vtrgb (it removes the custom remap), and
states that the font it builds is an OFL-1.1 Terminus derivative that must not
be called Terminus and that the optional 6x8 candidate embeds a GPL-2.0 kernel
bitmap. The radio-bridge header describes the four phases the script actually
runs instead of a pin-routing phase it never contained. Personal remarks in
comments are reworded impersonally.

`ruff format .` across the repo: 153 files, no behaviour change. This is the
second gate CONTRIBUTING.md promises, and until now it reported 154 files needing
reformat — so a first contributor ran the command the guide told them to run and
could not tell their own diff from the background.
Landed on its own, with nothing else in it, because a whole-repo reformat is only
safe to skip past in blame if it is provably nothing but layout. It was checked
that way rather than assumed: every changed file was formatted in memory and
compared by full `ast.dump()`, and 152 of 153 come out structurally identical
(the one exception was a docstring opening on a quote character, fixed in the
commit before this one). The string and comment token streams were diffed
separately, so a quote flip or an edited comment could not hide inside a
re-layout — five quote-style normalisations and sixteen implicit-concatenation
joins, all value-identical, and one commented-out line gaining the space after
its `#`. `meshterm specimen` is byte-identical on both platforms, and the suite
is 1888 green, gallery gate and `test_theme16` included.
What actually changed, in order of how much of the diff it is: wrapped calls and
signatures rejoin onto one line where they fit inside the hundred columns; the
magic trailing comma expands what it is there to expand; complex slices gain
their spaces (`[len(noise) :]`); a few redundant parens go. The tables that are
laid out to be read were fenced in the previous commit and are untouched here.
The aligned trailing-comment column is gone from about ninety lanes that were not
fenced — including the `heat.*` ladder in `MESH_THEME`, which cannot be fenced
where it sits. Every comment stays on the entry it describes, so nothing there
reads wrong; it just no longer lines up.
Add this commit to `.git-blame-ignore-revs`, which follows immediately.

The 46 missing docstrings, written rather than generated.
Most of the test ones already carried the explanation — as a comment sitting on
the first line of the body. That prose is the docstring; it was only in the
wrong place, so the config editor's PIN and lane tests keep their own words and
lose the duplicate comment. The rest are new: the two `repo` fixtures, the
counting `FakeDevice` in `test_device_state` (each method now says what it
answers *and* that it counts the call), the PicoCalc chrome and 16-slot theme
tests, and three one-offs.
In the package: `PathLine` and `FastRenderer`'s constructors point at the class
docstring that already documents their arguments rather than repeating it,
`SelectItem.__post_init__` and `courier_screen`'s opener say what they cache and
why, and `emoji_width.create_content` explains the memo it wraps the line lookup
in. `flash.py` and `uart1-mux.py` get theirs too, and `tests/__init__.py`
finally says what the package is.

`E501` across 69 lines, wrapped rather than exempted.
The prose ones — module docstrings in `menu`, `node_detail_screen`,
`pathline`, `pathgraph`, `walk_screen`, `trace_runner` and `test_about` — are
reflowed as paragraphs, so the block keeps its shape instead of gaining one
short orphan line. Nothing they say changed.
The code ones mostly gained a line break inside a call. Where a break would
have read worse than a name, the sub-expression got one instead: `reach` in
`topology`'s quality clamp, `plain_cells` in `pathline`, `numbering` in the
trace list, `listed` in `flash.py`'s refusal, and a small `shape`/`is_strip`
helper in two tests that were comparing or matching the same shape twice on one
line. Four docstring summaries lost a word they were not using.

The mechanical tail of the ruff pass, all of it behaviour-preserving.
`E741`: 29 uses of the ambiguous `l`, which reads as a `1` in most fonts.
Twenty-four of them held a rendered line and are now `ln`; three held an MVT
`Layer` and are now `layer`; two were a map label sorted by rank, now `lab`.
Renaming only the flagged line and then re-running `F821` was the check — a
half-renamed comprehension leaves a name nothing defines, so the linter finds
what a careful read might not.
`UP031`: 15 `%`-format strings become `.format` calls. `UP007`: the `CellStyle`
and `LabelT` aliases become `X | Y`; both are annotation-only, so the runtime
value never mattered. `E702`: four semicolon-chained `await` lines in
`test_device_state` get a line each.

DEPLOY_USER and MT_USER were overridable from the environment since the commits
that introduced them -- that part was always right, and is why they never moved
to .dev.env: they run on the target device, where a gitignored file on someone
else's workstation does not exist.
Only the fallback was wrong: it named one person, so a stranger who runs the
setup script unmodified gets a Linux account named after the maintainer. It is
`meshterm` now, and the comments describing it say the knob rather than the
value.
Nothing changes for the Lyra provisioned under the old name: these are one-time
setup scripts, and re-running one takes DEPLOY_USER set to the old name.

Every device address, login, key path, password and local venv path in the
.claude/ skills moves to dev.env at the repo root: gitignored, with a tracked
dev.env.example showing the shape. The skills now name $DEV_* keys and say to
read dev.env first, so they still run -- against whoever's hardware.
Two of the values were not secrets so much as a wrong assumption. The device
paths under that home directory are now $HOME-relative in run_instrumented.sh,
instrument.py and drive_console.py, and the deploy docs point at $DEPLOY_USER
and $KEY_PATH, which those scripts already parameterised. Hardcoding a home
directory was only ever correct for one machine.

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.

MeshTerm's live feed is built from RX_LOG_DATA events — every overheard
frame with its SNR/RSSI. pymc_core's frame server has push_rx_raw (the
0x88 push) but its _setup_push_callbacks never registers on_rx_log_data,
so it is never called: the promiscuous log is dropped and only adverts —
which carry their own wired advert_received push — reach the feed. The
radio was plainly hearing requests and channel text too; none of it showed.
Subscribe to the dispatcher's raw-packet feed directly and push each frame.
Routing through the dispatcher rather than on_rx_log_data keeps it clear of
the frame server's per-connection clear_push_callbacks(), and that feed
fires before dedup, so the client sees every repeat — what a live feed wants.
Same missing-wiring shape as the trace push; upstream fix is likewise to
register on_rx_log_data -> push_rx_raw in _setup_push_callbacks. Confirmed
against a live mesh: the feed now shows the full packet mix.

MeshCore has carried companion-over-hardware-UART for a long time — the defines
SERIAL_RX/SERIAL_TX, packaged per board as a *_companion_radio_serial env, and the
ESP32-S3 twin of this very board already uses the same D6/D7 pads. Our patch was
reimplementing it for the one platform it had never been wired into: at our old pin the
SERIAL_RX branches lived inside the ESP32 and RP2040 blocks and nRF52 fell through to
Serial. So the patch is now the two things actually missing, both upstream-shaped and
submitted: a Serial1 reference so the shared block compiles on nRF52, and the
Xiao_nrf52_companion_radio_serial env carrying the I2C escape in build_unflags rather
than editing the flags every XIAO env inherits.
Pin moves to a dev commit, since dev is the branch MeshCore takes work on.
flash.py grew the check that was missing when it mattered: a drive letter is not an
identity — when one board leaves the USB bus another inherits its letter — so it now
reads INFO_UF2.TXT and refuses a bootloader that isn't a XIAO, or that carries S140
6.1.1 and would take this S140-v7 image at the wrong address and never boot. It also
stops pretending copy-to-drive is the only route: our bootloader exposes a serial port
and no mass storage at all, so it prints the serial-DFU command instead of a dead end.
Verified from a clean clone at the new pin: env builds, uf2 converts to the same 811008
bytes at 0x27000 that is now running on the radio, and both Xiao_nrf52_companion_radio_usb
and Xiao_S3_WIO_companion_radio_serial still build, so neither side of the new #if moved.
The first cut pushed TRACE_DATA for any received trace packet, so every
trace read as an instant success: the dispatcher is promiscuous and fires
the packet-received callback for strangers' traces and for our own
outbound echoed back by the first repeater (same tag, still in flight).
Two corrections:
- Correlate against traces we originated. Wrap send_trace_path_raw (the one
send seam the frame server calls) to remember each tag and its route, and
push only a received trace whose tag we sent. Entries expire after 90s so a
never-answered trace can't match a recycled tag.
- Read the SNRs from the right place. A TRACE keeps its route (hop hashes)
in the payload unchanged; the per-hop SNRs ride in the packet *header* path
field, one signed byte (SNR*4) per hop. The earlier code waited for SNRs to
appear in the payload, so it never fired. Now completeness is "the header
has accumulated an SNR for every route hop", and that's the only thing we
push — the finished reply, with genuine per-hop SNRs.
Pending on-air verification (RF conditions poor at commit time); leaves
verbose per-trace INFO logging in place for that test, to be trimmed once a
clean multi-hop trace is confirmed.

pymc_core never forwards a received trace to the companion client: its
frame server registers every push callback except on_trace_received, and
nothing in the library ever fires the trace_received event, so the whole
path is dead code — the only push_trace_data call is the self-hop
shortcut in _cmd_send_trace_path. A trace sent from MeshTerm therefore
returns RESP_CODE_SENT and then times out, because the node parses the
reply and drops it.
Shim it at the dispatcher's packet-received callback (where CompanionRadio
already watches every RX packet with its measured SNR): wrap it, and for a
TRACE payload re-slice the on-air bytes into the hash/SNR blocks
push_trace_data wants, emitting the standard 0x89 frame the meshcore client
decodes. Verified byte-exact end to end. Handles both the SNR-per-hop
layout (final SNR from our reception) and firmware that trails the final
SNR in the payload.
Upstream fix (no local pymc_core checkout to carry it): mirror every other
push — fire trace_received from _on_packet_received and register
on_trace_received in frame_server._setup_push_callbacks.

JP drew a 53-cell MeshTerm at the original's height. It gets the same
colouring: the vertical ramp — white, yellow, light red, red, light
black — with every box-drawing character, shadow row and letter bevel
alike, in the light black.
The art moves to meshterm/assets/. It was sitting in meshterm/ui/ among
the modules, which is the wrong place for a file nothing imports; it
still ships inside the package, since the splash reads it at runtime and
an installed venv has no repo to read from. scripts/colour-logo.py paints
a .txt into its .ansi, so the palette is stated once in code instead of
retyped into escape sequences by hand, and re-styling stays a text edit.
Which mark is drawn is a question about the *screen*, not the platform: a
53-column console and a desktop terminal dragged narrow have the same
problem. load_logo(cols) answers it — widest that fits — and
compose_startup asks, since it is the only place that knows the width.
Below the smallest mark it returns nothing at all; no banner beats a torn
one. A test now draws the real wordmark at each platform's width, which
is the gate the splash never had (it is the one screen the gallery
doesn't cover, which is how a 71-cell mark shipped to a 53-cell console).

Writes the PSK straight to /var/lib/iwd/<SSID>.psk (same pattern
calculinux-setup.sh uses for first-boot provisioning) then asks iwd to
join right away. Self-elevates via sudo since that path is root-only.
Deployed to that user's ~/bin on the Lyra device (PATH updated in ~/.profile).

The board has no notion of local time -- glibc defaults to UTC -- so
astimezone() calls across the UI rendered heard-ages and timestamps in
UTC instead of JP's Eastern time. Adds a setup step that tries
timedatectl + tzdata's opkg feed first, falling back to a POSIX TZ
rule (America/Toronto and America/Montreal share the same US/Canada
Eastern DST rule since 2007) written to /etc/environment and that user's
~/.profile when the feed is unreachable, as it currently is.
Verified live on the deployed Lyra: UTC 03:17 now reads EDT 23:17
correctly through both a login shell and /etc/environment.

The Lyra has no battery-backed RTC, so every cold boot starts at the
kernel's build-time epoch until something sets it -- wrong for
heard-node ages, TTL, and the SQLite observation log until then.
Adds time-sync.service alongside wifi-kick.service: a oneshot unit
that waits for a real default route, then steps the clock via
whichever NTP client the image ships (chronyd/ntpd/sntp), falling
back to an HTTPS response's Date header if none is present.

The console keeps its stock kernel palette - black background, classic
PC hues - instead of the custom setvtrgb remap. MESH_THEME_16 is
re-tuned against the stock slots, which hands back the map's own
language for free: clients wear bright pink (13), repeaters purple (5),
rooms cyan (6), sensors brown (3). The cost is one dark grey - muted,
faint and track all collapse onto slot 8. Heat quantizes on plain human
units (15 min / 1 h / 1 day). The custom design is archived, not
deleted: theme._VT_SLOTS_CUSTOM + MESHTERM_CUSTOM_PALETTE=1 on the font
script reinstalls it, with the parity test keeping the two in sync.
Undoing the remap on the device exposed a trap: setvtrgb overwrites the
kernel's DEFAULT colormap, so the OSC palette-reset "resets" straight
back to the custom values - the script's default mode now programs the
stock palette explicitly (verified live; specimen screenshot in
.claude/plans/p3-specimen-stock.png).
The header also follows JP's spec: the handheld brands the app -
"MeshTerm vX" - instead of naming a soldered port that never changes,
and the activity pulse takes whatever room remains.
Also root-causes the intermittent suite flake: Rich memoizes a parsed
Style's ANSI codes on first render (Style.parse is globally cached), so
a raw hex style first rendered by a truecolor console replays 38;2
verbatim on a standard console later in the process. The specimen's
nodes row now wears the type.* theme styles - which is also just
correct: the marks now match the names row. Six consecutive clean
full-suite runs.
Deferred at JP's request: the glyph substitution map (he will redo it),
the F-key lane design (awaits his explicit spec), the CLI fold gap.

- BatteryService grows the host provider (Platform.battery="host"): the
PicoCalc's own pack through the kernel power_supply driver - a true
percent and charging flag from sysfs, no voltage-curve estimation, no
radio connection needed. Unreadable supply = absent, gauge hidden.
- The console-font script now builds TWO 512-glyph PSF2 fonts: the 6x12
Terminus-based default (53x26) and a 6x8 A/B candidate (53x40) based
on the kernel's own font_6x8 (CP437 coverage - documented as having
no Cyrillic), with the braille block at 2px dot pitch and all 18
marks redrawn for the shorter cell. Built and verified live on the
Lyra: stty reports 53x40 under meshterm8, specimen legible
(.claude/plans/p5-specimen-6x8.png); flip with setfont, persist the
winner in vconsole.conf. JP judges the A/B by eye.
- calculinux-setup.sh puts the deploy user in input/dialout/video
(input is the modifier watch's /dev/input access).
- theme's platform binding now drops the fold table and cache on every
switch: its emoji pads bake in cell_len at build time, which the
regular platform's emoji-width calibration can re-measure - a stale
table survived platform swaps in randomized test runs.

The first P3 (a84abf3) ran on the wrong model and its palette never
reached the TUI: MESH_THEME_16 was written in 256-colour cube indices
instead of the 16 VT slots, and the platform theme pick was wired into
the scripted-CLI console while the real rasterizer stayed hardcoded to
truecolor. Replace it end to end:
- theme._VT_SLOTS: the canonical slot->RGB design (conventional hue
families kept; slots 5/6 become the track/faint slates), MESH_THEME_16
rewritten against color(0..15) with the VT's bold-as-brightness and
dim-bank-background rules pinned by tests. /etc/vtrgb + a boot oneshot
install it (console-font script), OSC fallback when kbd is absent.
- platforms.on_platform: set_platform now re-runs registered bindings,
so theme, rasterizer and widgets swap implementations once per switch
and hot paths read module globals - no per-call get_platform().
- The render-boundary fold (theme.fold_text): one str.translate pass
(NFKD accent folds - the Terminus base has no accented Latin - plus
symbol stand-ins and the width-padded emoji map), an embedded-SGR
quantizer for canvas truecolor, and a ?-at-own-width catch-all that
makes the no-wide-glyph short-circuit true by construction. Applied at
the only two places every visible byte passes: render_to_ansi and
MapCanvas.to_ansi_lines.
- ui/fontset.py freezes the installed font's inventory (dumped live);
the gallery now asserts rendered picocalc ANSI carries no truecolor/
256-colour SGR and no character outside it - the parity gate the
first attempt faked by asserting a dataclass field.
- Font build: nine new 6x12 marks (ellipsis, warn, backspace, shift,
gear, refresh, clock, crosshair, padlock) drawn into donor slots, with
donor misses now fatal and a keeper canary (donating pi once erased
Cyrillic pe - shared slot). Table re-dumped on-device: identical to
fontset.py, 519 = 519.
- Type-based name colouring: registry moved to core/nodetypes (services
no longer import ui), fed from monitor observations, heard_nodes and
merge_contacts. Heat gradient quantizes to heat.* steps on picocalc.
- ui/marks.py: the P2-deferred constant relocation - widgets no longer
drags map_render/mapcanvas/pathgraph for tuples and aliases.
- meshterm specimen: the visual language on one card through the real
funnels - the on-device acceptance screen (JP's request).
- tools/chat: delivered/no-ack state uses the standard check/query
marks, not the banned emoji pair.
Verified on the Lyra: font+palette installed, specimen framebuffer
captures in .claude/plans/. 1259 tests green, 13 xfailed (P6 list).
