gofmt: restore import grouping after the module rename
CI / test (push) Successful in 5s
The rename to git.ryuvia.com/niklas/... was a plain string substitution, so it left the import blocks in their old order. The new path sorts before github.com/go-chi/..., where the old one sorted after, which gofmt considers unformatted. go vet does not look at import order, so CI had nothing to say about it. |

Move to Gitea: git.ryuvia.com/niklas/terdut-server
CI / test (push) Successful in 2m15s
The module path, the container image, the Helm chart and the CI pipeline all named GitHub. They now name the Gitea instance everything else already runs on. The workflows are rewritten rather than translated. Gitea's runner image is ubuntu:22.04, whose nodejs is Node 12, so no JS action runs there at all -- actions/checkout@v4 dies with a SyntaxError before it does anything. Every step is shell, checkout is a plain clone (this repo is public, so it needs no credential), and the jobs that need docker or helm run in host mode because the dind bridge a `container:` job gets cannot reach github.com or get.helm.sh. Two consequences worth naming: - upload-artifact/download-artifact are also JS actions, and there is no artifact store here, so the job that builds the binaries is the job that publishes them. Nothing is passed between jobs. - setup-qemu-action is gone with the rest, and the runner has no binfmt registration. The Dockerfile's builder stage now runs on $BUILDPLATFORM and cross-compiles from TARGETARCH instead, which is what keeps the arm64 image buildable -- and makes it native rather than emulated. The chart moves from a GitHub Pages index to an OCI artifact in Gitea's registry. Publishing stays tag-only for the reason recorded in release.yaml: a workflow triggered by the branch push cannot know the version it is about to be tagged with. The GitHub repository is left in place and untouched. Nothing pushes to it any more, but its existing release downloads and chart index keep resolving. |

Page the on-call person when an incident opens
An incident opened, got assigned to whoever held today's schedule entry,
and then sat there silently until somebody thought to look. The schedule
and the incident model were both built; nothing reached the person
holding the pager.
Notifications go out through ntfy, over plain HTTP with no new
dependencies. Delivery is an outbox rather than an inline call: the pool
is limited to a single connection, so a POST made while holding the
webhook's transaction would stall every other request behind it. The
webhook inserts a row and a notifier goroutine sends it within a tick,
retrying with exponential backoff.
Only opening an incident has to resolve a topic from scratch. Reminders
and all-clears reuse whatever that first notification chose, which keeps
configuration out of resolveIfSettled and gives the right rule for free:
you only hear that something resolved if you were told it started.
Each push carries an Acknowledge button, because the useful thing to do
at 3am is stop the pager without unlocking anything. It POSTs to an
unauthenticated /api/notify/ack/{token} — a notification body lives on
the ntfy server and in the device cache, so a real API key must never
appear in one. The token is minted per delivery, scoped to one incident
and one action, and expires in a day.
Reminders repeat until the incident stops being untouched. The stop
conditions are the states that already mean somebody has it: acknowledged,
snoozed, resolved, archived. Snooze is the mute button, so there is no
separate reminder cap.
Notifications sent to the fallback topic carry no Acknowledge button. The
topic is shared, and a button on it would let any subscriber acknowledge
as somebody else.

Turn incoming alerts into incidents
Release / build (amd64, linux) (push) Failing after 11s
Release / build (amd64, darwin) (push) Failing after 12s
Release / build (arm64, darwin) (push) Failing after 11s
Release / build (arm64, linux) (push) Failing after 11s
Release / release (push) Has been skipped
Release / chart (push) Failing after 13s
Release / docker (push) Failing after 19s
The alerts row was both Alertmanager's record and the human work queue, and
the two have different owners. The webhook upsert rewrites that row on every
notification; acknowledgement, comments and archiving were columns on it that
the upsert happened not to touch. So an alert that resolved and re-fired days
later still read as acknowledged by whoever acked the first occurrence — the
ack outlived the thing it referred to. Nothing recorded transitions either:
rows are mutated in place, so there was no timeline and no way to compute how
long anything took.
Alerts are now read-only signal records with two states, and incidents are
the work item: triggered, acknowledged or resolved, with an assignee, a
snooze, notes and an append-only timeline. Many alerts map to one incident,
and a new occurrence opens a new incident, which is what makes a stale ack
impossible rather than merely unlikely.
Correlation uses Alertmanager's own groupKey. It already grouped the alerts
according to the group_by routing tree the operator configured and sends the
result on every webhook, where it was being discarded; adopting it means
changing group_by in alertmanager.yml changes correlation here, with no
second grouping scheme to configure and keep in sync.
An incident opens only when an alert transitions into firing — an unseen
fingerprint, a newer startsAt, or a resolved alert starting again. The
unchanged notifications Alertmanager re-sends every repeat_interval are none
of those. That rule is what lets manual resolution be terminal: without it,
closing an incident by hand would be undone by the next re-send of an alert
that never stopped firing, and the button would be a lie. Snooze covers the
"not now" case instead. Incidents otherwise resolve by cascade, once every
alert under them has stopped firing, whether by webhook or by expiry.
New incidents are assigned to whoever holds today's schedule entry. The
schedule table has existed since the first release with nothing reading it.
Also here, following from the split:
- Incident severity is a high-water mark over its alerts, never lowered.
An incident that hit critical was a critical incident, and downgrading a
live one would demote it in the queue while the work is still open.
- /api/stats/incidents reports MTTA and MTTR, null rather than zero until
there is something to average. Neither was computable before.
- Alert archiving becomes sweeper-only housekeeping; the archive people
interact with is the incident's.
Breaking: the alert acknowledge, archive and comment endpoints are gone, and
the alert object drops the acknowledgement fields and gains incident_id. The
README maps each removed endpoint to its replacement. Migration 008 backfills
an incident per existing alert, archived ones included so no comment is
orphaned, carrying acknowledgements across and turning comments into timeline
notes.
Both documented alert contracts are untouched: received_at still advances on
every accepted payload, re-sends included, and resolution_source still says
how much to trust ends_at. The upsert is byte-for-byte what it was, now
running inside the ingest transaction.
