It was the only service here publishing on 0.0.0.0, and a published docker port
is not behind the firewall: docker writes its DNAT rules straight into the nat
table, which ufw's INPUT chain never sees. `ufw default deny incoming` never
covered 80/443/81 — ufw-docker-rules.conf on the host exists to patch exactly
that, and patching a rule is weaker than never opening the socket.
The address is read from `tailscale ip -4` at run time rather than passed in,
because the host provisioning has already done `tailscale up` by the time this
executes. It is validated against 100.64.0.0/10, the range tailscale and
headscale both allocate from. SETUP_NPM_BIND overrides it.
With neither, selecting NPM exits instead of falling back to 0.0.0.0 — a
fallback would silently undo the point of the change.
Two consequences worth knowing. tailscaled becomes a boot-order dependency, so
the script warns when it is not enabled at boot; docker's restart policy covers
the window but only if the tailnet comes up on its own. And HTTP-01 ACME
challenges can no longer reach port 80, so any certificate NPM issues now needs
DNS-01.

scripts/ was holding two unrelated kinds of thing: install-this-machine, and run-this-occasionally. The
eight installers now live in scripts/setup/; what stays at the top level is the build steps (gen-index,
prebuild, build/) and the two maintenance scripts (reindex-music, rebuild-soulseek-tree).
The move is not just a rename. Three of these derive the repo root from their own location:
setup.sh:51 PROJECT_DIR="$(dirname "$SCRIPT_DIR")"
setup_mac_light.sh:51 same
cleanup-desktop.sh:134 ENV_FILE="$(dirname "$0")/../.env"
Left alone, all three would now resolve to scripts/ — and nothing downstream complains. PROJECT_DIR is
where .env is written, where `bun install`, `gen:index` and `db:push` run, and what pm2 is pointed at, so
a fresh install would have quietly provisioned scripts/ and reported success. cleanup-desktop.sh fails
the other way: it would find no .env, print "No .env — skipping", and leave the real VNC_PASSWORD in the
real file. All three are now `../..` with a comment saying why the level matters.
provision-user-dirs.ts imports data-path.ts relatively; that one tsgo caught.
Also disambiguated `setup.sh` where it had become two files. app-store/templates/<name>/setup.sh is a
per-sidecar installer with its own contract, and preflight.ts + docs/sidecar-app-store.md discussed both
in the same paragraph. The host one is now spelled with its full path at those sites.
Verified: bash -n on all six shell scripts, tsgo clean, os-user tests pass, both derivations resolve to
the repo root, starship.toml still resolves from os-user-shell.ts, and provision-user-dirs.ts runs under
DRY_RUN.
