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).

fix: collapse --dry-run flag parser to single-arg case (no while/case loop)

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.

lib/hvault.sh uses secret/ mount prefix but migration policies use kv/ — agents will get 403 #890

Summary

S2.1 lands the policy files and apply script. Both are correct and well-structured.

Script correctness (`tools/vault-apply-policies.sh`)

Token resolution chain is complete. hvault_token_lookup calls _hvault_check_prereqs → _hvault_resolve_token, which exports VAULT_TOKEN from env or /etc/vault.d/root.token. So when fetch_current_policy references ${VAULT_TOKEN} inside its subshell, the variable is guaranteed to be populated. ✓

Subshell + EXIT trap pattern is correct. The RETURN-trap gotcha is documented and avoided — the subshell's EXIT fires on any exit path including set -e abort, so the tmpfile cannot leak. ✓

Content comparison is sound. Both desired=$(cat "$f") and current=$(fetch_current_policy ...) go through command substitution, which strips trailing newlines consistently on both sides. The comparison is symmetric and won't spuriously flip to "updated" due to trailing-newline differences. ✓

Dry-run guard ordering is correct. The dry-run block exits before the VAULT_ADDR check and hvault_token_lookup probe, so --dry-run requires no Vault access as documented. ✓

hvault_policy_apply confirmed. The function exists in lib/hvault.sh (line 183), accepts NAME FILE, JSON-encodes the content via jq -n --arg policy, and PUTs to sys/policies/acl/<NAME>. Matches what the script expects. ✓

Policy file correctness

All families follow their documented patterns:

bot-* — kv/data/disinto/bots/<role>/* (read) + kv/metadata/... (list,read) + kv/data/disinto/shared/forge/* (read). Nine files, all consistent. ✓
service-* — kv/data/disinto/shared/<name>/* + metadata. Two files, consistent. ✓
runner-* — Single kv/data/disinto/runner/<TOKEN> path, read only, no metadata/list. Six files. The deliberate omission of list/metadata is correct per AD-006 (least-privilege per dispatch). ✓
dispatcher — runner wildcard + ops-repo paths, both data and metadata. ✓

All HCL paths use kv/ as the mount name, consistent with the KV v2 convention documented in the AGENTS.md.

Tech debt filed

Pre-existing mount mismatch in lib/hvault.sh: hvault_kv_get, hvault_kv_put, and hvault_kv_list all use secret/data/ and secret/metadata/ as path prefixes (lines 117, 157, 173), but the policies in this PR and the migration convention use kv/ as the mount name. Any agent calling hvault_kv_get will hit secret/data/... but only hold ACL for kv/data/..., producing a 403 at runtime. This is not introduced by this PR — filed as tech debt separately.

Verdict

APPROVE — Script is correct, policies are consistent, idempotency contract is sound; one pre-existing tech-debt issue filed separately.
