Cairo's toy text API binds one face with no per-glyph fallback, so an
emoji in a calendar event title rendered as a box in Noto Sans.
text/measure/advance now split strings into runs and draw emoji runs
(U+1F000-1FAFF, U+2600-27BF) in monochrome Noto Emoji, restoring the
caller's face afterwards. Nerd Font PUA icons stay in FONT_MONO.
Plain strings and invalid UTF-8 take the old single-call path.
No shaping: ZWJ sequences and flags draw as their parts. Pango via
lgi (built for Lua 5.4) is the upgrade path.

Sum drm-resident-vram0 from DRM fdinfo, the same per-client counters
gputop reads, counting each drm-client-id once since a client repeats
its totals on every fd it holds. One grep over /proc/*/fdinfo, about
10ms warm, sampled through new_gate every ~2s.
The 12 GiB total is hardcoded: xe exposes no VRAM capacity in sysfs.

Conky gives Lua no way to request one redraw, so a scroll showed up to
2s late. Pointer enter and leave, which Hyprland sends on every toggle
of the special workspace, now switch conky_set_update_interval between
0.1s and the config's 2s.
At that rate the CPU and network counters would sample over 0.1s
windows and the chart would fill 20x faster, so both now sample through
data.new_gate on the /proc/uptime clock, about every 2s, and redraw
their last values in between. The samplers move to texeci: execi runs
in the main loop and a 0.7s nvtable or an Immich download stalled the
scroll.
Measured: about 12% of one core while visible, 0.5% while hidden.

Moves the nvchecker/nvtable table the login shell printed onto the
dashboard, as a wide card at the bottom centre. bin/updates-sample.sh
caches `nvtable -C -E` every ten minutes and starts nvchecker, fully
detached, at most every 30 minutes. The widget parses the cache and
colours it in the board's language: installed behind upstream is
critical, a shipped .info behind is a warning, with nvtable's status
dots per row and a legend on the bottom line. The mouse wheel scrolls
rows that do not fit.

A day with no memories left the card showing only a notice. When today
has none, immich-fetch.sh now merges the memories of each of the past
six days, skipping a day whose request fails, and marks the index with
a scope week line. The subtitle names where the photos come from,
Today or This week, before the i/n counter, and the empty notice reads
no memories this week.

A centred card showing today's "N years ago" photos from Immich, one at
a time on a 30-second rotation, with when each was taken and where.
bin/immich-fetch.sh runs from conky's execi every 30 minutes: it asks
/api/memories for today, converts each preview to PNG (Cairo loads
nothing else) and writes an index with the year, local capture time and
place. The place needs the key's asset.read permission and reads '--'
without it. The key lives in ~/.config/udt/immich.env, like the weather
key, because a GPG-backed store would raise a pinentry unattended.
The dashboard now registers lua_mouse_hook and hands pointer events to
the widget under the pointer. On this card, scrolling steps through the
photos and a left click opens the photo in Immich's web UI and hides the
dashboard so the browser is not stuck beneath it.

Replaces the Waybar module that used to show breaktimer.sh with a card
on the dashboard. The card's big value is the phase countdown, coloured
by phase with the same language the Waybar module used, and two rows
name the phase and what the countdown leads to.
Data comes from bin/breaktimer-sample.sh, run by conky at execi 5, which
reads the daemon's runtime files into a cache. The sampler owns the
kill -0 liveness check, because conky's Lua cannot run a process and a
dead daemon must read as 'fermo' rather than a stale 'running'.
Drops outside the work-hours window freeze the countdown while the phase
stays 'working'. The sampler detects this from the remain file's age and
the card reads it as 'outside working hours', which also covers a hung
daemon. The phase words and colour roles live in data.breaktimer_parse
so they are unit-tested; the card only draws the result.

The month grid with the week's appointments below it, colour-coded by
calendar. Events come from a cache file rather than a live call: khal
costs about 200ms of Python startup, which is two orders of magnitude
over the 2-second draw budget, so bin/calendar-sample.sh writes the
cache on a 5-minute execi and the widget only parses.
Calendar colours are read out of khal's own config by the sampler and
mapped onto the board's palette roles, so the card follows a scheme
change instead of pinning three literal hues.
khal will not emit an ISO date: {start-date} uses the user's dateformat,
which carries no year here, and a strftime spec inside the field raises.
The sampler asks for {start-date-long} and data.calendar_date recovers
the numbers by position, resolving day/month by magnitude and reading a
genuinely ambiguous pair day-first. A 2-digit year is refused rather
than guessed at.

Two lines on one chart against a shared ceiling, one sample per pixel column
so nothing is interpolated. The history is module state sized from the card's
width, so moving the card reframes the window rather than clearing it.
The public address is refused once stale: an address that may no longer be
yours, displayed with confidence, is worse than a dash.
The fixture uses TEST-NET-1. This repository is public.

Free space is read rather than derived: size - used overstates it by the
root-reserved blocks, tens of gigabytes on a large filesystem, none of it
available to anyone but root.
Also asserts fs[3], the row whose device name ends in a digit. It sits next
to a numeric column and is the row most likely to break a parser counting
fields, and nothing covered it.

The pattern required a literal CPU token immediately before the @, which the
one Intel fixture happens to carry. A Xeon reads 'E5-2680 v4 @ 2.40GHz' and a
Tiger Lake 'i7-1165G7 @ 2.80GHz', so both kept their clock on the card.
A generation prefix hid the vendor word from its anchor for the same reason:
'11th Gen Intel Core i7-1165G7' kept 'Intel'.
Three more forms added as tests. The Intel fixture was meant to keep the
stripping a rule, and one fixture was not enough to do it.

Stripping by rule rather than by a table of known parts: a leading vendor
word, trademark noise, a trailing core count or clock. The Intel fixture
exists to keep it a rule.
DMI placeholders read as no board at all. 'To Be Filled By O.E.M.' on the
dashboard is worse than a blank row.

Only the first space separates, so a value keeps its own spaces. Values stay
strings: the sampler writes epochs and the widget decides whether an age
reads as hours or days.

The widget passes conky's update_interval rather than letting it default, so
the argument path is the one that ships and nothing exercised it.

Mirrors new_cpu_counter: cumulative counters need two samples to yield a
rate, and each direction carries its own previous reading.
Clamps a negative delta to zero rather than letting a 32-bit wrap or an
interface reset produce a spike. One bogus sample sets the shared autoscale
and flattens the entire window.

A ring left its line width behind, so the next stroke on the card inherited
a hairline several pixels thick. It already restored the cap for the same
reason.
card.truncate replaces byte slicing, which cuts a multi-byte character in
half and emits an invalid sequence Cairo draws as a box.

Fix the conky.conf.in comment to name all three samplers and the README
to say the cache sampler runs every 15 minutes. Rewrite the disks layout
comment to match per_row = n (no wrapping), drop the stale "seventeenth
bar" note, and record in the spec that the cache age marker is
deliberately deferred with the epoch-line upgrade path.

The test comment said "cpu_percent", but the API is new_cpu_counter()
plus :sample(). Prose only, the code was always consistent, but a
comment naming a nonexistent function sends the next reader looking
for it.

Load is a delta, so one reading cannot yield a percentage. The first
call returns nil rather than a fabricated number: 100% on startup reads
as a real spike.
A non-advancing counter also returns nil instead of dividing by zero,
and the result is clamped because a suspend/resume can produce a
nonsense delta.

Parsers take file contents as a string, not a path, so they test
against committed fixtures with no filesystem mocking.
hwmon is globbed by its name file rather than a fixed index, carried
over from the old config: indices drift across kernel reorders and a
stale one silently reads a different chip.
Failure returns nil, never 0. A sensor reading 0 C is legitimate, so 0
cannot double as an error value.
