RFC 6238 says the verifier must reject a code it has already accepted: a code
stays valid for its whole thirty-second window, so one seen in flight — a
phishing page, a proxy, over the shoulder — could be replayed until it expired.
Tasks now record the counter of the last accepted step (totp_last_step), and a
login accepts a code only when its step is strictly greater. The guard is in the
UPDATE, not a read-then-write, so two logins racing with the same stolen code
cannot both find the old value and both proceed — exactly one moves the row.
auth.TOTPStep is VerifyTOTP that also reports which step matched, walking the
same one-step window; the code entered a little early or late spends the step it
was issued at, not the step it was checked at, so a late-but-valid code is still
single-use. Verified end to end: the same code presented to two logins in one
window is accepted once and refused the second time.

To huller fra sikkerhedsgennemgangen, og de er samme historie fortalt to gange:
den ene kontrol, der findes til når adgangskoden allerede er tabt, kunne omgås af
netop den, der havde adgangskoden.
**H1 — spanden blev fyldt af adgangskoden alene.** `handleLogin` nulstillede
ratebegrænseren ved hver korrekt adgangskode, *før* den så på, om der var en
andenfaktor. Det gav én, der havde kodeordet, ubegrænsede portioner på ti gæt:
log ind, få en frisk spand og en frisk ventende session, brug ti gæt på koden, log
ind igen. Med tre gyldige koder i ethvert øjeblik og tyve forespørgsler i
sekundet er det lige odds inden for en eftermiddag.
Spanden ryddes nu først, når login er *færdigt*, og der er kommet en spand mere:
koder tælles pr. konto og ikke kun pr. adresse. Adressespanden er slået af enhver
med mere end én adresse, hvilket er det almindelige — en telefon og en bærbar er
allerede to. Det, der gør en sekscifret kode sikker, er at gæt er en knap
ressource, og knapheden skal tælles imod det, der bliver angrebet.
Den ventende session får lov at leve. At afslutte den ved første forkerte ciffer
blev overvejet og valgt fra: det ville koste en, der taster ét tal forkert, sin
adgangskode igen, og det køber næsten ingenting oven i loftet pr. konto.
**M3 — et lækket token kunne tilmelde sin egen andenfaktor.** `/auth/totp/setup`
lå kun bag `requireAuth` og spurgte om ingenting, mens `disable` altid har
krævet adgangskoden: døren åbnede med et token og lukkede kun med et kodeord. Et
stjålet token kunne hente hemmeligheden, lægge den i sin egen godkender, bekræfte
den og beholde den eneste kopi af gendannelseskoderne. Ejerens næste login ville
stoppe ved en kode, de ikke havde, og de kunne ikke slå den fra uden at logge ind
først. Et tyveri bliver til et lejemål — den sætning står allerede i filen ved
siden af om passkeys, og det er den samme regel.
Nu bag `requireSession` sammen med passkeys og sessionerne, og `setup` spørger om
adgangskoden ligesom `disable`. Symmetrien er pointen: at slå den til er mindst
lige så indgribende som at slå den fra.
Og en note kan oprettes inde fra et projekt. At ligge i et projekt *er* måden en
note deles på, så det er én handling frem for to — man skulle før oprette noten
under Noter og bagefter finde projektet frem i "Del i". Ruden findes nu, også før
der er en eneste note, for ellers er der ingen knap dér, hvor man opdager at der
skal skrives noget ned.

I dag, Kommende, Venter og Indbakken kan trækkes i den rækkefølge, man vil have
dem. På kontoen frem for i browseren: sidebjælkens bredde er en kendsgerning om
skærmen, og svaret på en telefon er ikke svaret på en skærm — men hvilken
rækkefølge man vil have dem i, er en kendsgerning om personen.
En liste af nøgler frem for et tal pr. visning. Ukendte nøgler droppes og
manglende føjes til sidst, så en visning kan tilføjes eller fjernes uden at
strande nogens rækkefølge — hvilket allerede er sket én gang, da Færdige
forlod menuen.
To ting, prøverne fandt undervejs, og begge var mine:
Rækken som trækgreb gjorde alt indeni trækbart, og sidebjælken er allerede
modtager for opgaver — en opgave trukket til I dag holdt op med at lande, fordi
rækken havde taget gestussen. Et lille greb tager ingenting, før man griber det.
Og drop-håndteringen slugte begivenheden, før den tjekkede, om den overhovedet
var en menuflytning.
Migration 0019.

Serveren svarede 502 med en forklaring, og Cloudflare erstattede kroppen med sin
egen side. Bevist i produktion: handleren skrev 122 bytes JSON på 38 ms med
teksten "the panel refused: HTTP 401", og browseren fik en HTML-fejlside. Det
gjaldt også Gmail, som bruger samme hjælper — derfor har fladen hele tiden kunnet
sige "noget gik galt" og ikke andet, selv om serveren vidste præcis hvad der var
sket.
En proxy har lov til at gøre det ved en origin-5xx. Så det er ikke Cloudflare,
der skal laves om: 502 var den pæne kode, ikke den brugbare. Upstream-afvisninger
er nu 422, som går uændret igennem. Navnet StatusUpstreamRefused står ét sted med
grunden, så det ikke bliver rullet tilbage af en, der med rette synes 502 lyder
mere rigtigt.
Fladen læste altid fejlkoden i kroppen og ikke statuskoden, så der var intet at
rette dér.

Reported from use: "Fetch now" said "something went wrong" and the error log was
empty. Both halves were the same bug wearing two hats.
`handleGmailSyncNow` answered 502 with the code `internal_error`, which the
interface maps to a generic sentence — so Google's own words, which are the whole
diagnosis, were replaced by one that says nothing. And `writeError` records
nothing; only `s.internal` does. So there was no message to read and nowhere to
look it up afterwards.
`s.upstream()` is the answer: 502 because this is somebody else's service saying
no rather than this server breaking, a code of its own so the interface can quote
what was said, and a row in the error log — which is the entire reason that log
exists. A Gmail sync failing quietly for a week is otherwise invisible: the
background job writes a line the next restart erases.
The same connection also left the mailbox unnamed. The address is learned at
connect time and that call can fail; a warning went to the log and an empty string
to the database, so the page said "an unknown account" and kept saying it. The only
way back was to disconnect and reconnect, which nobody would guess. The status
endpoint asks again when it finds none, so a wrong answer lasts until the next look
rather than until somebody reconnects.
Ten Danish strings were hiding in `confirm()` and `app.toast()` calls, including
every destructive confirmation in the app — the worst possible set to leave in one
language, since it is what somebody reads in the half-second before agreeing to
lose something. The i18n guard reads markup and attributes, and a string argument
lives in the script block. It reads those now, and found four my own grep missed.

Three things reported from use, all in the sidebar.
Projekter, Delt med mig, Filtre and Etiketter fold, the way a project group
already does. Kept on the account rather than in localStorage, and for the same
reason the group's own `collapsed` is: folding a heading says "this is the part
of my work I am not in right now", and that is as true on the laptop as on the
desktop. The sidebar's *width* is the opposite case and stays per browser. A JSON
array of keys rather than a column each, so a renamed heading is not a migration.
The group heading is no longer indented — only what is filed under it. The colour
dot sat as a sibling before the fold button and pushed the whole row in, and a
heading that starts further in than the rows above it says the heading is inside
something.
And the colour is chosen while renaming. The dot was itself the button, which
gave the heading four controls on a line narrow enough to crowd the name; both
are edits to the same thing, so they belong in the same moment. The form closes
on `focusout` and only when focus has left it entirely, and the swatches refuse
focus on mousedown — Safari and Firefox do not focus a button on click, so
`relatedTarget` would be null and the form would shut under the pointer.

The panel's watcher reported four 5xx today — twice from one address at
11:49, twice from another at 10:45 — and there is no way to find out what
any of them were. verdande logs the real cause of every 500, but on a Rune
the log belongs to the container and the container is replaced on every
restart. So an operator is told that something broke and given nothing to
act on, which is the worst of both: alarming and useless.
Every 500 now writes a row: what the handler was attempting in its own
words, the error it hit, the method and path, who was asking, and the
request id that ties it back to the log line for whoever still has it. The
"what" is the part a status code cannot give — "list projects" and "move
task" are the difference between a fault you can find and one you can only
count.
Written best-effort and never checked. This is the path that is already
reporting a failure, and a diagnostic that can itself fail the request
would turn one broken screen into two.
Threading the request through `internal()` and `storeError()` touched 108
call sites across 19 files, which is the price of not having had it there
from the start. It is mechanical and the compiler checked all of it.
Kept for thirty days by the nightly sweep: long enough to answer "what
happened last week", short enough that a fault loop cannot fill the volume
the tasks live on.
Read at Indstillinger → Fejl, administrators only — it carries paths,
account names and the server's own error strings. The empty state says
"Ingen fejl registreret. Det er den rigtige tilstand", because a blank
panel should not read as a broken one.
The test drops a table and asks for the endpoint that reads it: the same
code path a disk error takes, and the row that comes back has to name the
operation, the account and the request.

docs/api.md has told people to make a token under Settings since it was
written. The store has held CreateAPIToken, ListAPITokens and
DeleteAPIToken since the first migration. There were no routes: nothing
between the two, and no way to make one.
GET, POST and DELETE under /tokens, all behind a new requireSession
middleware. A bearer token is refused there with 403 even though it is
accepted everywhere else — otherwise a leaked token is permanent, because
whoever has it issues a second one and revoking the first changes
nothing. The plaintext comes back from POST and never again; only the
hash is stored, so the interface has to say so at that moment rather than
offering a reveal that cannot work.
PATCH /auth/me alongside it. Name, timezone and language could not be
changed anywhere — not through the API and not through the interface —
and an account created from an invite inherits a default timezone. That
is not cosmetic: every date in the app is resolved in it, so somebody in
another country had every due date land an hour out with no way to say
so. The zone is validated against the running system's database rather
than a list kept here, which is the same database the dates are resolved
with. The email address stays read-only: it identifies the account and is
what invites were sent to.

Sessions are stored as hashes, so a database dump contains nothing that
can be pasted into a browser. A login that has passed the password but
not the second factor is modelled as a pending session: it expires, is
revocable, and reaches exactly one endpoint.
Signup is invite-only and takes the email address from the invite rather
than the form, so a link cannot be redirected to somebody else. The
first admin is created by an endpoint that refuses once any account
exists, checked and inserted in one transaction because it is
necessarily unauthenticated.
Login failures and forgotten-password requests answer identically
whether or not the address has an account — otherwise the form is an
account-existence oracle. Password rules are a length floor and nothing
else: composition rules push people towards worse passwords.
