# Credential lane implementation
One S3 queue for three designed lanes; each task keeps its own approval,
execution and closure boundary. This replaces the implementation tasks in the
three completed design workplans, not the designs themselves. No approval is
inherited by consolidation. INTENT binding: secure custody, dependable delivery,
stable consumer interfaces. Incident custody remains in RPF-WP-0027/0029.
## Consolidate completed designs and owner dependencies
```task
id: RPF-WP-0035-T01
status: done
priority: medium
state_hub_task_id: "0f3606bb-e95b-5484-8a57-bcdd6e3916fd"
```
Completed 2026-09-05. Preserved the three designs under
`docs/credential-lane-designs/`, identified native owner responsibilities and
linked each superseded task below. Owners have not been sent new requests and
no new external acceptance is claimed. STATE-WP-0085-T09 is already done;
the signing dependency belongs to the proposed FLEX-WP-0020-T05 cutover.
## Accept and provision secrets-engine service JWT login
```task
id: RPF-WP-0035-T02
status: wait
priority: high
state_hub_task_id: "e0c82ea9-05a5-537e-8fbf-67534263572e"
```
Supersedes RPF-WP-0032-T02. Design:
`docs/credential-lane-designs/secrets-engine-service-jwt.md`.
Platform owns the exact JWT mount/role/policy, effective-policy negative tests
and a metadata-only custody receipt. KeyCape owns issuer/JWKS and service
registration (KEY-WP-0009); secrets-engine owns service authentication and
authority consumption (SECRETS-WP-0008-T06, SECRETS-WP-0007-T04).
**Unblock:** confirmed HTTPS issuer/JWKS, exact claims and audience, consumer
readiness, approved source and attended apply authority. A service login does
not grant lane mutation authority. Do not build another identity provider or
lifecycle engine here.
**Done when:** approved exact role succeeds for the intended service, wrong
issuer/audience/subject/claims and unrelated secret access fail, bounded TTL
and revocation are proven, the consumer explicitly opts into the verified
contract, and rollback/cleanup receipts contain no secret material.
## Implement the platform operator-write CCR contract and Fluid lane
```task
id: RPF-WP-0035-T03
status: wait
priority: high
state_hub_task_id: "f47e5bc5-6f3c-54bb-aa35-260ad03892ba"
```
Supersedes RPF-WP-0033-T02. Design:
`docs/credential-lane-designs/fluid-telegram-operator-kv.md`.
Platform owns the per-path capability schema/validator, exact OpenBao policy
and accepted custody coordinates. MASON-WP-0005 owns construction coordination
and engine integration; KeyCape/NetKingdom own OIDC/MFA and group membership;
FT-WP-0002 owns client CAS, prefix correction, output containment and Telegram
application acceptance. Retain the existing read-only CCR semantics.
**Unblock:** accept tenant/path and per-entry field/capability matrix; confirm
actual group/assurance and callbacks, reviewed construction contract and writer
authority. Contract review can proceed without a live credential; the final
schema cannot be treated as accepted solely because a draft exists.
**Done when:** validation rejects broad/unsupported grants, the consumer proves
CAS=0 first-write behavior and no value output, approved identities can perform
only the exact matrix, negative/expiry/revocation checks pass, custody is seeded
through the separate writer, and the verified route has a safe handoff receipt.
The unattended adapter remains a separate demand and gets no operator session.
## Accept the needed signing lane and deliver it to the owning runtime
```task
id: RPF-WP-0035-T04
status: done
priority: medium
state_hub_task_id: "35a85846-61d5-54ce-8b18-ede45733d53c"
```
Supersedes RPF-WP-0034-T02. Design:
`docs/credential-lane-designs/state-hub-preflight-signing.md`.
Platform owns signing-key custody, exact read policy/role and scoped delivery
acceptance. State Hub owns API chart/env wiring, all-replica rotation fencing
and health. FLEX-WP-0020-T05 owns the rename preflight/cutover dependency;
STATE-WP-0085-T09's adoption-plan delivery is already complete.
**Unblock:** State Hub/repo-manager and the consuming migration owner confirm
that this transitional State Hub lane is still needed during retirement;
record the target runtime, namespace/SA/auth audience and an executable
rotation fence, plus approved writer and deployment window. Do not broaden the
lane into a general repository-rename authority or provision for a stale demand.
**Done when:** protected one-time generation, API-only ESO delivery, negative
access checks and a non-mutating signed preflight pass; every API replica uses
the accepted version; rotation/invalidation and recovery are evidenced. No
repository rename is part of S3 lane acceptance. If demand is withdrawn, record
the owning decision and cancel this task explicitly rather than provision it.
2026-09-05 continuation: verified the live primary cluster identity and healthy
single API replica; the signing ExternalSecret is still absent. Added a writer
guard against wrong-cluster kubeconfigs before any OpenBao access. The default
workstation kubeconfig's local port-forward listener was unavailable. Activation
still needs the contained attended OIDC/MFA login and the acceptance evidence
above; source preparation is not live completion. See
`history/2026-09-05-preflight-signing-activation-readiness.md`.
Completed 2026-09-05: user-led attended activation generated version 1 and
rotated to version 2 with every API replica stopped. Exact access and negative
identity checks passed; ESO delivery and API-only exposure passed; the recovered
single API replica accepts new signed preflight and rejects its predecessor by
signature, with healthy primary identity and no preflight blockers. State Hub
chart commit `49e3182`, Helm revision 59. No repository rename executed.

## Admit KeyCape approval-engine client custody and delivery
```task
id: RPF-WP-0035-T05
status: wait
priority: high
state_hub_task_id: "e15d62c9-e5da-5721-a135-87c050f7851c"
```
Answers KEY-WP-0013-T02 (State Hub message
`278a3ebe-b529-49f6-bd1a-e3ebcf318260`). Admission:
`docs/credential-lane-designs/keycape-approval-clients.md`; requests
`CCR-2026-0017` (secrets-engine-approval) and `CCR-2026-0018`
(approval-engine-operator).
Platform owns the two custody paths, exact-path read policies, Kubernetes auth
roles and the KeyCape-side ESO delivery. KeyCape owns the client registrations,
issuance, claim set and disablement; approval-engine owns approval semantics and
audit of emitted actions.
2026-09-08 admission response: both proposed KV paths confirmed unchanged; field
`client_secret` corrected to `CLIENT_SECRET` for the uppercase KV convention and
CCR validator. Kubernetes delivery references confirmed against the live `sso`
namespace, which already resolves `KEYCAPE_RAPP_QONTO_CLIENT_SECRET` through the
same `secretKeyRef{key: client-secret}` shape on image `main-153258b`. Attended
authority named as the governed `openbao-platform-admin-login` lane
(`founder_required`); KeyCape's refusal to treat its generic `warden plan`
database match as authorization was correct. Rollout agreed as one attended
session with the KeyCape reading build pinned but undeployed, ordered after the
Authelia issuer precondition in message `c8b1ad10-dae8-48fb-a0ea-7e2a101c54bf`.
Policies, ClusterSecretStores and ExternalSecrets are written and validated,
none applied.
**Unblock:** owner approval of both CCRs, a KeyCape image that reads both
environment names, the settled Authelia `iss` pin, and a founder-attended window
date. Verifier-side custody only — no client-side read lane is admitted, and no
scope beyond the two declared sets.
**Done when:** both CCRs are approved, the attended window seeds both KV paths
with CAS=0, policies/roles/stores/ExternalSecrets apply and sync, the KeyCape
build resolves both environment names, KeyCape evidences live JWKS signature and
exact claim bindings with excess scopes denied (operator `consume`, human
`consume`), platform evidences cross-path/wrong-identity/out-of-namespace denial,
and every receipt is metadata-only. If either registration is abandoned, KeyCape
disables it before the KV version is destroyed.
### 2026-09-08 actual upstream issuer returned
The admitted KeyCape one-shot probe verified the actual signed upstream issuer
as **`https://auth.coulomb.social`** at 21:44:44 UTC. Signature, audience,
validity window and nonce checks passed and the pinned Job exited 0. All
five temporary resources and the Pod were removed; normal KeyCape Deployment
and config Secret metadata are unchanged. See
`docs/evidence/2026-09-08-keycape-upstream-issuer-proof.json`.
T05's unknown-issuer input is resolved. The configuration owner still ensures
`authelia.issuer` equals that exact HTTPS value before the custody window.
Both CCRs remain proposed and await the named reviews; this probe grants no
custody mutation or client-side read. Keep the current authority preflight and
this signed-token proof as separate receipts. Live ESO/client/approval and
separate audit/client-side custody acceptance remain open.
## Dependency review — 2026-09-06
SECRETS-WP-0008-T02 now records the local PIP claim/validation join implemented
and tested. Its remaining gate is the unreachable approval-engine claim endpoint
and access-engine Check (SECRETS-WP-0007-T04). Do not carry forward the old local
stub as a blocker. T02 still needs the accepted service issuer/JWKS, claims,
audience and consumer binding. T03 still needs confirmed operator group/tenant
and consumer semantics; T04 is already complete. No new owner acceptance inferred.
### 2026-09-08 attended capability preflight
HFACT-WP-0001's continued execution verified the existing first-provision
front door without provisioning anything. `warden plan` selected
`openbao-platform-admin-login` / founder_required / one oidc_login. The native
`scripts/openbao-attended-exec.py` supplied the existing WSL browser launcher;
a direct attempt had no launcher and failed before handoff. Its first revocation
result was unconfirmed and is preserved in the receipt rather than silently
reclassified. The two subsequent contained sessions completed self-revocation
and helper cleanup.
`scripts/keycape-approval-custody-preflight.py --receipt <new-private-file>` is
a silent, read-only command for that envelope. The installed Bao CLI supports
one path per `token capabilities` call; the final run used six single-path calls.
Create/update authority is present on both exact policy paths, both Kubernetes
auth-role paths and both KV data paths from CCR-2026-0017/0018. This is authority
metadata, not a secret-data read or policy/role/KV mutation. Receipt:
`docs/evidence/2026-09-08-keycape-approval-custody-preflight.json`.
T05 remains wait: both CCRs are still proposed, the actual upstream ID-token
issuer precondition remains open, and no verifier-side credential is provisioned.
Client-side retrieval and audit-sender custody are still separate owner returns.
The capability receipt is not a review approval or service readiness proof.
