Slice 1b of the self-update story. The installer now sets up a versioned
layout — install extracts the resource-manager tarball to a staging dir,
reads the VERSION it contains, moves the dir to /opt/furtka/versions/<ver>/,
and creates /opt/furtka/current as a symlink pointing at it. All runtime
references (Caddy, wrapper, systemd ExecStart) go through /current, so
Phase 2's self-update just flips the symlink atomically.
Systemd units move from hand-written files in /etc/systemd/system/ to
`systemctl link /opt/furtka/current/assets/systemd/*` — one link per
unit, stable across upgrades because the link target is /current. The
furtka-status + furtka-welcome units now ExecStart the shipped scripts
directly from /opt/furtka/current/assets/bin/, which means we no longer
copy those scripts to /usr/local/bin/ at install time.
Runtime JSON (status.json, furtka.json, update-state.json) moves to
/var/lib/furtka/ so self-updates never clobber it. Caddy serves those
three paths from there; everything else from /opt/furtka/current/assets/www/.
The __HOSTNAME__ sed-template hack is gone. At install time we write
/var/lib/furtka/furtka.json with {hostname, install_date, version}, and
the landing page's JS reads it on load to populate the hostname chip
and to build the SMB deep-link for the fileshare tile. First paint gets
a "—" placeholder and hydrates once fetch completes.
Test updates:
- test_webinstaller_assets enforces the new command shape (extract-to-
staging, ln -sfn /opt/furtka/current, systemctl link per unit,
no writes to /srv/furtka/www/).
- test_app's legacy "payload present" / "payload absent" tests match
the new layout too.

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.
