Slice 1a of the self-update story. Every HTML/CSS/shell-script/systemd-
unit payload that used to live as a triple-quoted string constant inside
webinstaller/app.py now lives as a real file under furtka/assets/:
furtka/assets/Caddyfile
furtka/assets/VERSION (new — matches pyproject.toml)
furtka/assets/www/{index.html, settings/index.html, style.css, status.json}
furtka/assets/bin/{furtka-status, furtka-welcome}
furtka/assets/systemd/furtka-{api,reconcile,status,welcome}.service
furtka/assets/systemd/furtka-status.timer
The installer now pulls each file from disk via _read_asset(). Byte-for-
byte identical output at install time — a fresh-ISO install should land
the same files in the same places with the same contents, verified by
tests/test_webinstaller_assets.py which reconstructs each base64 blob
and asserts equality against the on-disk asset.
iso/build.sh also copies furtka/assets/ next to the webinstaller source
at /opt/furtka/assets on the live ISO so _resolve_assets_dir() finds
them with a "next to me" lookup. In dev the same function walks two
levels up to the repo copy, so pytest works without any env vars.
furtka-status.sh drops the /etc/furtka/version TODO — it now reads
/opt/furtka/VERSION directly, which Slice 1b will upgrade to
/opt/furtka/current/VERSION once the symlink layout lands.
_FURTKA_WRAPPER_SH (the 5-line /usr/local/bin/furtka shim) stays inline;
it's tiny and not asset-shaped.
