# Agent Harness — OpenBao Secret Lanes (BINKY-WP-0004-T03)

The agent harness (DEC-2026-002 resolved: single shared runtime repo `agent-harness`, deployed on Railiance)
needs three credential lanes. One exists and is reusable; two need
provisioning.

## Lane 1 — LLM provider key: REUSE (verified)

Warden catalog `openrouter-llm-connect` (active, resolvable, reviewed
2026-07-02):

- Path: `platform/workloads/activity-core/llm-connect/llm-connect-provider-secrets`
- Field: `OPENROUTER_API_KEY`
- Auth: any token carrying policy `workload-kv-read-llm-connect-provider-secrets`
- Policy gate: `flex-auth check secret.read:llm-connect` (advisory today)

**Verdict: reuse.** The key is scoped to "llm-connect in activity-core"; the
agent harness is the consumer that scoping anticipated (it executes tasks
activity-core emits, via llm-connect adapters). No new secret needed. If the
worker later gets its own workload identity, bind that identity to the same
policy — same secret, separate auth principal — rather than duplicating the
key.

## Lane 2 — Forgejo deploy key: NEW (Red lane)

No warden catalog entry exists (checked 2026-07-17; nearest match falls
through to `key-cape-oidc-login`). The worker must push commits to target
repos on forgejo (railiance01:30022), starting with a sandbox repo (T04),
later binky-control (T06).

Proposed provisioning (founder Red lane, ~10 min):

1. Generate an ed25519 keypair on Railiance (worker host), private key never
   leaves the host; store a copy under OpenBao
   `platform/workloads/agent-harness/forgejo-deploy-key`
   (fields: `SSH_PRIVATE_KEY`, `SSH_PUBLIC_KEY`).
2. In forgejo, add the public key as a **per-repo deploy key with write
   access** — sandbox repo only at first; add binky-control at T06 cutover.
   Per-repo deploy keys beat a machine-user account here: blast radius is
   exactly the repo list.
3. New OpenBao policy `workload-kv-read-agent-harness-forgejo` scoped to
   that path; warden catalog entry `agent-harness-forgejo-deploy` (owner:
   railiance-platform, risk: high).

## Lane 3 — Non-interactive AppRole for company-email scan: NEW (Red lane)

Blocker being closed: the existing OIDC role
`binky-company-email-imap-workload-kv-read` is browser-interactive with a
15-minute TTL — unusable for recurring scans (email-integration checklist
item 9, `integrations/company-email-openbao.md`).

Proposed provisioning (founder Red lane, ~10 min):

1. Enable/confirm AppRole auth on the OpenBao instance (`bao auth list`;
   enable at path `approle` if absent).
2. Create role `agent-harness-binky-mail` bound to the **existing** policy
   `workload-kv-read-binky-company-email-imap` (no policy change needed):
   `token_ttl=15m`, `token_max_ttl=30m`, `secret_id_ttl=0` (or rotate
   quarterly), `token_num_uses` bounded.
3. Deliver `role_id` + `secret_id` to the worker host via the
   secrets-engine delivery mechanism (files `0600` on Railiance, outside any
   repo). The worker logs in per run:
   `bao write auth/approle/login role_id=… secret_id=…` → short-lived token
   → `bao kv get -field=IMAP_USERNAME|IMAP_PASSWORD tenants/binky/company-email/imap`.
4. Warden catalog entry `agent-harness-binky-mail-approle` (owner:
   railiance-platform, risk: high) so the lane is discoverable and audited.

Scan invocation stays exactly the manual pattern (read-only email-connect,
values only ever in process env):
config `integrations/mailbox-binky-company.yml`, reports to
`mailmeta/reports/`.

## Founder Red-lane summary

- [x] Lane 2: forgejo deploy key (generate, register on sandbox repo, store
      in OpenBao, catalog entry) — **done 2026-07-17** on railiance01;
      write deploy key on `coulomb/executor-sandbox`; catalog
      `agent-harness-forgejo-deploy`. Add `binky-control` deploy key at
      cutover only.
- [x] Lane 3: AppRole `agent-harness-binky-mail` (create role, deliver
      role_id/secret_id to Railiance, catalog entry) — **done 2026-07-17**;
      host dir `~/.local/agent-harness/approle-binky-mail`; catalog
      `agent-harness-binky-mail-approle`. Positive IMAP field presence +
      negative sibling-path deny verified (no values logged).
- [x] Lane 1: nothing to do — reuse confirmed

T04 (worker MVP) can start with Lane 1 alone plus a workstation-side dry
run; Lanes 2–3 gate unattended operation, not development.

Host env helper (railiance01): `source ~/.local/agent-harness/env` sets
`BAO_ADDR`, `EXECUTOR_APPROLE_DIR`, and `PATH` for `bao`. Git SSH alias:
`forgejo-agent-harness` → forgejo.coulomb.social:30022 with the deploy key.
