# Hardening Backlog — Exit From Bootstrap Mode
The MVP runs in **bootstrap mode**: stage roles may be driven by temporary
root-created OpenBao tokens read from mode-0600 files. That is acceptable setup
material, **not** the steady state. This backlog tracks the work to retire it.
The MVP is honest about this: bootstrap mode is a documented, bounded phase with
explicit revocation tasks — not a hidden permanent security posture.
## H0 — Revoke outstanding bootstrap tokens (always-on hygiene)
Every minted bootstrap token has a revocation task. Track each here:
| Token file | Stage | Minted | TTL | Revoked? |
| --- | --- | --- | --- | --- |
| `~/.secrets-engine/bootstrap/prod.token` | prod | (n/a — demo uses dev server) | 1h | n/a |
| `~/.secrets-engine/bootstrap/prod-warden-sign.token` | prod | SECRETS-WP-0004 live lane applied via attended operator flow; file use not recorded in repo | 1h | cleanup/revocation evidence not recorded |
| `~/.secrets-engine/bootstrap/prod-whynot-design.token` | prod | SECRETS-WP-0003 live apply/provision/publish 2026-07-03 | 1h | file shredded 2026-07-03; accessor revoke deferred (OpenBao sealed; 1h TTL likely expired) |
Revoke: `bao token revoke -accessor <accessor>` then `shred -u <file>`.
For SECRETS-WP-0004, the scoped `warden-sign` token used for the 2026-06-29
smoke had a `15m` TTL; explicit accessor revocation and handoff-file cleanup are
operator-side hygiene if any material remains. Do not record accessors or file
contents in this repo.
## H0a — Revoke pilot workload tokens
| Credential | Custody path | Minted | Revocation task | Revoked? |
| --- | --- | --- | --- | --- |
| whynot-design Gitea bot npm/package token | OpenBao lanes `whynot-design-npm-publish` + `platform/workloads/coulomb/whynot-design/npm-publish`; handoff file shredded after provision | SECRETS-WP-0003 publish `@whynot/design@0.4.1` 2026-07-03 | Rotate in Gitea when TTL/policy requires; handoff source file deleted with `shred -u` after provision | handoff shredded; lane value remains in OpenBao |
## H1 — Replace bootstrap token files with OIDC / service auth
- Implemented consumer scaffold: exact KeyCape client-credentials exchange,
claim/lifetime preflight, strict client-secret file input, renewal boundary,
and no implicit fallback.
- Remaining: railiance-platform stands up the exact-bound OpenBao JWT auth
mount/role and publishes its non-secret connection contract.
- secrets-engine logs in via that method instead of reading a token file.
- Remove `--bootstrap-token-file` from the steady-state path (keep only for true
break-glass, heavily audited).
## H2 — Response-wrapped handoff
- Add a `wrapped` delivery mode using OpenBao response wrapping for operator
handoff flows where exec-time injection does not fit.
## H3 — Production dual-control
- Implemented consumer validator: exact action request, decision digest/binding,
validity, State Hub provenance, and caller-selected minimum distinct approval
count.
- Remaining: State Hub stores/serves the durable object and production handlers
resolve it; all production live actions currently fail closed.
## H4 — Rotation & lifecycle states
- Implement `rotate` and persistent `compromised` / `deactivated` lane states
with evidence. Explicit suspend/deactivate/destroy plans now exist, and
ordinary `revoke` safely aliases native AppRole/policy deactivation, but lane
state and coordinated provider/workload rotation remain outstanding. Live
destroy remains disabled until exact-action authorization is available.
## H5 — Audit report command
- Implemented: `secrets-engine audit <catalog-id>` summarizes allowlisted local
action/result, decision, session-cleanup, and State Hub delivery evidence.
- Implemented: idempotency/source headers and edge-relay queued-receipt/outbox-id
visibility.
- Remaining: operator replay verification and OpenBao audit request-id
correlation.
## H6 — API service mode
- Expose the stabilized CLI semantics as a local service API for ops-warden,
CI, agents, and a future UI — **after** the CLI contract is proven.
## Exit criteria for "bootstrap mode is over"
- No steady-state flow reads a bootstrap token file.
- Every stage role authenticates through OIDC/service auth.
- Production provisioning beyond the pilot requires dual-control.
- Rotation and deactivation are first-class, evidenced operations.
