Wires S0.1–S0.3 into a single idempotent bring-up script and replaces
the S0.1 stub in _disinto_init_nomad so `disinto init --backend=nomad
--empty` produces a running empty single-node cluster on a fresh box.
lib/init/nomad/cluster-up.sh (new):
1. install.sh (nomad + vault binaries)
2. systemd-nomad.sh (unit + enable, not started)
3. systemd-vault.sh (unit + vault.hcl + enable)
4. host-volume dirs under /srv/disinto/* (matching nomad/client.hcl)
5. /etc/nomad.d/{server,client}.hcl (content-compare before write)
6. vault-init.sh (first-run init + unseal + persist keys)
7. systemctl start vault (poll until unsealed; fail-fast on
is-failed)
8. systemctl start nomad (poll until ≥1 node ready)
9. /etc/profile.d/disinto-nomad.sh (VAULT_ADDR + NOMAD_ADDR for
interactive shells)
Re-running on a healthy box is a no-op — each sub-step is itself
idempotent and steps 7/8 fast-path when already active + healthy.
`--dry-run` prints the full step list and exits 0.
bin/disinto:
- _disinto_init_nomad: replaces the S0.1 stub. Invokes cluster-up.sh
directly (as root) or via `sudo -n` otherwise. Both `--empty` and
the default (no flag) call cluster-up.sh today; Step 1 will branch
on $empty to gate job deployment. --dry-run forwards through.
- disinto_init: adds `--empty` flag parsing; rejects `--empty`
combined with `--backend=docker` explicitly instead of silently
ignoring it.
- usage: documents `--empty` and drops the "stub, S0.1" annotation
from --backend.
Closes#824.

Adds the Vault half of the factory-dev-box bringup, landed but not started
(per the install-but-don't-start pattern used for nomad in #822):
- lib/init/nomad/install.sh — now also installs vault from the shared
HashiCorp apt repo. VAULT_VERSION pinned (1.18.5). Fast-path skips apt
entirely when both binaries are at their pins; partial upgrades only
touch the package that drifted.
- nomad/vault.hcl — single-node config: file storage backend at
/var/lib/vault/data, localhost listener on :8200, ui on, mlock kept on.
No TLS / HA / audit yet; those land in later steps.
- lib/init/nomad/systemd-vault.sh — writes /etc/systemd/system/vault.service
(Type=notify, ExecStartPost auto-unseals from /etc/vault.d/unseal.key,
CAP_IPC_LOCK granted for mlock), deploys nomad/vault.hcl to
/etc/vault.d/, creates /var/lib/vault/data (0700 root), enables the
unit without starting it. Idempotent via content-compare.
- lib/init/nomad/vault-init.sh — first-run init: spawns a temporary
`vault server` if not already reachable, runs operator-init with
key-shares=1/threshold=1, persists unseal.key + root.token (0400 root),
unseals once in-process, shuts down the temp server. Re-run detects
initialized + unseal.key present → no-op. Initialized but key missing
is a hard failure (can't recover).
lib/hvault.sh already defaults VAULT_TOKEN to /etc/vault.d/root.token
when the env var is absent, so no change needed there.
Seal model: the single unseal key lives on disk; seal-key theft equals
vault theft. Factory-dev-box-acceptable tradeoff — avoids running a
second Vault to auto-unseal the first.
Blocks S0.4 (#824).

Lands the Nomad install + baseline HCL config for the single-node factory
dev box. Nothing is wired into `disinto init` yet — S0.4 does that.
- lib/init/nomad/install.sh: idempotent apt install pinned to
NOMAD_VERSION (default 1.9.5). Adds HashiCorp apt keyring and sources
list only if absent; fast-paths when the pinned version is already
installed.
- lib/init/nomad/systemd-nomad.sh: writes /etc/systemd/system/nomad.service
(rewrites only when content differs), creates /etc/nomad.d and
/var/lib/nomad, runs `systemctl enable nomad` WITHOUT starting.
- nomad/server.hcl: single-node combined server+client role. bootstrap_expect=1,
localhost bind, default ports pinned explicitly, UI enabled. No TLS/ACL —
factory dev box baseline.
- nomad/client.hcl: Docker task driver (allow_privileged=false, volumes
enabled) and host_volume pre-wiring for forgejo-data, woodpecker-data,
agent-data, project-repos, caddy-data, chat-history, ops-repo under
/srv/disinto/*.
Verified: `nomad config validate nomad/*.hcl` reports "Configuration is
valid!" (with expected TLS/bootstrap warnings for a dev box). Shellcheck
clean across the repo.
