Wires Nomad → Vault via workload identity so jobs can exchange their
short-lived JWT for a Vault token carrying the policies in
vault/policies/ — no shared VAULT_TOKEN in job env.
- `lib/init/nomad/vault-nomad-auth.sh` — idempotent script: enable jwt
auth at path `jwt-nomad`, config JWKS/algs, apply roles, install
server.hcl + SIGHUP nomad on change.
- `tools/vault-apply-roles.sh` — companion sync script (S2.1 sibling);
reads vault/roles.yaml and upserts each Vault role under
auth/jwt-nomad/role/<name> with created/updated/unchanged semantics.
- `vault/roles.yaml` — declarative role→policy→bound_claims map; one
entry per vault/policies/*.hcl. Keeps S2.1 policies and S2.3 role
bindings visible side-by-side at review time.
- `nomad/server.hcl` — adds vault stanza (enabled, address,
default_identity.aud=["vault.io"], ttl=1h).
- `lib/hvault.sh` — new `hvault_get_or_empty` helper shared between
vault-apply-policies.sh, vault-apply-roles.sh, and vault-nomad-auth.sh;
reads a Vault endpoint and distinguishes 200 / 404 / other.
- `vault/policies/AGENTS.md` — extends S2.1 docs with JWT-auth role
naming convention, token shape, and the "add new service" flow.

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.
