Comments and attachments close out phase 2. Files are stored
content-addressed by hash, so the path never contains anything the
uploader chose — a filename is attacker-controlled text, and building a
path from it is how "../" becomes a write outside the data directory.
Everything downloads as application/octet-stream: an uploaded SVG served
inline would run its own script on this origin with the session cookie
attached.
Web Push is written directly against RFC 8030/8291/8292 rather than
pulled in — it is three specs' worth of well-defined crypto and about
two hundred lines, and the alternatives carry a JWT and crypto stack
each larger than the file.
Phase 4 imports Todoist's CSV and exports it back. Todoist numbers
priorities the opposite way to how it displays them — its 4 is P1 — so
the two are converted rather than copied; getting it backwards silently
inverts the urgency of every imported task. Nesting is positional, so
the reader keeps an indent stack and the writer never sorts.
The round trip is tested as the brief asks: a CSV in, out, and back
produces an identical project, and two exports of one project are
byte-identical.

The HTTP server serves /healthz, the API namespace and the PWA, with the
frontend embedded behind a build tag so a clean checkout compiles without
a Node toolchain. /healthz reads the database rather than just answering:
a process that cannot reach its own data is not healthy, and a 200 there
would keep a broken container in rotation.
The image is distroless and static — the SQLite driver is pure Go, so
CGO stays off. The Rune manifest uses keep_entrypoint because there is
no shell in the image to run a startup command with, and its log watchers
match the JSON log format the container actually emits.
