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.

CI's duplicate-detection step (sliding 5-line window) flagged 4 new
duplicate blocks shared with lib/init/nomad/cluster-up.sh — both used
the same `dry_run=false; while [ $# -gt 0 ]; do case "$1" in --dry-run)
... -h|--help) ... *) die "unknown flag: $1" ;; esac done` shape.
vault-apply-policies.sh has exactly one optional flag, so a flat
single-arg case with an `'')` no-op branch is shorter and structurally
distinct from the multi-flag while-loop parsers elsewhere in the repo.
The --help text now uses printf instead of a heredoc, which avoids the
EOF/exit/;;/die anchor that was the other half of the duplicate window.
DIFF_BASE=main .woodpecker/detect-duplicates.py now reports 0 new
duplicate blocks. Behavior unchanged: --dry-run, --help, --bogus, and
no-arg invocations all verified locally.

Land the Vault ACL policies and an idempotent apply script. 18 policies:
service-{forgejo,woodpecker}, bot-{dev,review,gardener,architect,planner,
predictor,supervisor,vault,dev-qwen}, runner-{GITHUB,CODEBERG,CLAWHUB,
NPM,DOCKER_HUB}_TOKEN + runner-DEPLOY_KEY, and dispatcher.
tools/vault-apply-policies.sh diffs each file against the on-server
policy text before calling hvault_policy_apply, reporting created /
updated / unchanged per file. --dry-run prints planned names + SHA256
and makes no Vault calls.
vault/policies/AGENTS.md documents the naming convention (service-/
bot-/runner-/dispatcher), the KV path each policy grants, the rationale
for one-policy-per-runner-secret (AD-006 least-privilege at dispatch
time), and what lands in later S2.* issues (#880-#884).
