Create a period with a start, an end and a label, see the twelve months
ahead at a glance, delete one. The label is required and trimmed: it
goes straight onto the shop window.
Overlapping periods are refused, and the message names the one they
collide with. Two rows covering the same day would both be "in effect"
with no way to say which, and silently merging them would lose whichever
label the owner meant. Periods that merely touch — one ending the 10th,
the next starting the 11th — are fine.
The year view exists because a list of date ranges is precise and hard
to picture, while "have I left a gap in August?" is the question people
actually ask. It renders on the server; it only changes when the data
does.
A vacation period stays a source of truth and is never expanded into
exception rows, so a one-off exception placed inside one still wins and
nothing is overwritten. The page says so rather than leaving it to be
discovered.
The first version of the calendar built the months but never applied the
periods to them, so no closure would ever have shown. Caught before
commit.

The first administration page, built for the actual use case: a phone
held in one hand behind the counter. One card per day, native time
inputs so the platform keyboard does the work, and the consequences
shown before the save rather than after — the footer names which days
are about to change, and the button stays disabled until something
actually has.
"Duplicate onto the other open days" leaves closed days closed. Someone
copying Tuesday's hours means "the days I open, I open like this", not
"open seven days a week".
Validation runs in the browser for the feedback and again in the action
before the write: the client is a convenience, not a guarantee, and this
is the schedule the shop window shows. A day being closed drops its
leftover slots rather than failing on them.
A save that changes nothing writes nothing — no rows, no audit entry,
and so no needless panel redraw. Reordering slots does not count as a
change. The audit diff stores one readable line per day in French, so
the log can be read without cross-referencing the schema.
The editing helpers are pure and tested, and the write path is tested
against a real database including the read-only refusal.
Test files now run sequentially: the integration files share one
database and each truncates it, so parallel files raced. The suite takes
six seconds; giving every file its own database would buy nothing.

The panel now pairs, fetches its image and files its logs against this
application rather than against the TRMNL cloud.
Four endpoints: /api/setup issues a token on first contact,
/api/display hands back an image and a wake interval, /api/log stores
firmware diagnostics, and /api/device/image/<hash> serves the bytes.
The wake interval is where freshness and battery are traded off. In BYOS
nothing can be pushed: the device sleeps, wakes, asks and sleeps again.
So the interval is short while the shop trades and long overnight, and
it is shortened further whenever a change of state falls inside it —
the door opening in twenty minutes means waking in twenty-one,
whatever the base interval says.
The image filename is the hash of its own bytes. The firmware skips the
redraw when the name is unchanged, which is the whole battery strategy,
and the URL is immutable, unguessable and safe to cache forever. Two
integration tests pin this: unchanged data must yield the same filename
and store one row, changed hours must yield a different one.
MAC addresses are normalised before use. They are a primary key here,
and firmwares are inconsistent about case and separators; without this a
panel could register twice by capitalising itself differently. Header
names are read in both the hyphen and underscore spellings for the same
reason — the TRMNL docs and the Seeed sources disagree, and being
liberal costs nothing while being wrong costs a blank shop window.
Pairing is deliberately made to survive a rendering failure. The token
is issued once and only its digest is kept, so a device stranded by a
failed response would be registered yet hold no credential, and unable
to register again. The welcome image is worth far less than that. This
was found by running the flow, not by reading it.
satori, yoga and harfbuzz are marked external: bundling rewrites the
relative path satori uses to load its WebAssembly, and the renderer dies
on a missing hb.wasm.
The integration tests run against a real Postgres, in CI too. Mocking
Prisma here would only prove the mock works.
