# KeyCape factor credential custody — 2026-09-13
User-authorized attended setup is live under RPF-WP-0040 / CCR-2026-0023.
The operator authenticated through the contained OpenBao login lane. No
credential value was included in source, receipts, chat or ordinary logs.
Dedicated privacyIDEA identity `keycape-factor-reader` has `tokenlist` permission
for `coulomb`. Its password is in a separate OpenBao issuer path; KeyCape
receives only a provider-issued, expiring JWT via External Secrets. Explicit
fallback policy preserves existing administrators' prior rights and excludes
this service identity. The service cannot read provider administration policy.
Live checks passed:
- Exact OpenBao policy/role readback, audience and service-account bindings.
- Provider-issued credential, cross-user factor visibility, and the actual
KeyCape `user` + `realm` + `active=True` lookup shape.
- Wrong service account rejected; issuer password and sibling KV reads denied.
- ExternalSecret `sso/keycape-factor-read`: Ready=True / SecretSynced.
- Initial renewal Job published KV version 2 and revoked its OpenBao session.
A second Job published version 3; the existing mounted file received the
replacement and provider lookup accepted it without a pod restart.
- KeyCape config activation passed server dry-run and UID/resource-version CAS;
readback confirmed all other Secret data and configuration bytes preserved.
Deployment rolled out successfully with the existing image
`sha256:c9eb584d60efecfe00e1745a7e8cd3ebb4ae0f94faa715ef9594cd58a5dcebb6`.
- Fourteen offline tests cover identity/expiry/status rejection, scope boundaries,
failed-provider preservation, CAS failure, session-cleanup failure, retry,
ambiguous config rejection and byte-preserving activation.
Runtime source: `manifests/keycape-factor-custody.yaml`; renewal every ten minutes,
ESO refresh every minute. Renewal runs as non-root with an immutable ConfigMap,
digest-pinned image, dedicated service account and restricted network policy.
The reader has no issuer-password permission; the renewer cannot write that
password. OpenBao sessions last at most fifteen minutes (ESO) or five minutes
(renewer). Successful renewal workers revoke their sessions explicitly.
Repeat: `make keycape-factor-tests` and `make keycape-factor-live-acceptance`.
Exact-commit CI is `.forgejo/workflows/keycape-factor-acceptance.yaml`.
The first proof Job was `keycape-factor-delivery-acceptance`; its short-lived
reader session expires by its fifteen-minute maximum TTL. The final reusable
proof also revokes its session; its result is recorded below after execution.
Limits: this establishes credential custody, renewal and native delivery.
Genuine provider JWT expiry/revocation drills remain RPF-WP-0040-T04; renewing a
JWT does not revoke its predecessor. Optional-after-enrollment policy remains
unchanged. OTP onboarding, lost-factor recovery and their complete platform-admin
browser journeys remain KEY-WP-0035 / USER-WP-0030. Historical resolver incident
NK-WP-0033 is not closed by this new service lane.
Final reusable proof passed: `keycape-factor-proof-0c4a6929`. All eight checks
were true: wrong-SA rejection, issuer-password denial, sibling-secret denial,
mounted-token/custody equality, KeyCape per-user lookup, provider administration
denial, renewed projection acceptance, and explicit reader-session revocation.
KeyCape remained Ready 1/1 at deployment generation 46. CCR validation passed.

## KeyCape factor service lane — authorized setup, 2026-09-13
RPF-WP-0040 / CCR-2026-0023 establish a new dedicated service lane. The user,
acting as platform operator, authorized establishing storage/delivery and performed
attended OpenBao authentication. This is separate from the historical resolver
repair lanes above; their incident receipts are not retroactively completed.
| Purpose | KV v2 CLI path | Fields | Consumer |
| --- | --- | --- | --- |
| Scoped provider JWT | platform/workloads/net-kingdom/keycape-factor-read | TOKEN, EXPIRES_AT, REQUEST | KeyCape via namespace-scoped ESO and adminTokenFile |
| Renewable service login | platform/workloads/net-kingdom/keycape-factor-issuer | USERNAME, PASSWORD, REQUEST | Owner bootstrap, then dedicated renewal worker; never KeyCape |
Provider identity: keycape-factor-reader (local privacyIDEA service admin).
Effective permission: tokenlist for realm coulomb only. Preserve the existing
no-admin-policy baseline for other administrators using an explicit fallback
that excludes this service identity. Only the two reviewed named policies may
be introduced; unexpected existing admin policies abort setup.
Generate the service password in owner-process memory and persist with KV CAS=0
before provider creation, allowing interrupted setup to resume. The attended
worker passes values through stdin/captured pipes only, never argv or receipts.
Only explicit KV absence permits creation. Existing request provenance and
policy definitions must match; retries do not rotate an existing identity.
Reader policy: workload-kv-read-keycape-factor-read, role
keycape-factor-workload-kv-read, bound sso/keycape-factor-eso, audience openbao,
15-minute maximum OpenBao session, no default policy. Metadata apply/readback
passed via the attended owner envelope. Provider issuance, native ESO delivery,
KeyCape mounted-file activation, per-user lookup and rotation without restart
passed. The reader can inspect and revoke only its own OpenBao session in
addition to reading the exact JWT data/metadata paths. See the acceptance record
`docs/evidence/2026-09-13-keycape-factor-custody.md`.
Provider JWTs expire independently of OpenBao sessions. Require 5 minutes to
2 hours remaining lifetime at issuance; renew well before expiry. Disable the
service's tokenlist policy (while retaining fallback exclusion) to withdraw its
factor access; do not rotate privacyIDEA's global signing key as routine renewal.
Verify expiry/permission refusal separately from OpenBao self-revocation.
Renewal: `sso/keycape-factor-renewer` runs every ten minutes under its own
service account, with a five-minute maximum OpenBao session. Its separate policy
reads the issuer password and reads/writes only the delivered JWT path. The
worker verifies provider identity, expiry, factor lookup and denied policy
administration before a CAS write and readback, then revokes its session.
ESO refreshes once per minute. KeyCape mounts only `admin-token`, mode 0440,
through fsGroup 65534; the issuer password never enters its namespace Secret.
Operations: `make keycape-factor-tests` runs offline failure/retry and config
preservation tests. `make keycape-factor-live-acceptance` creates bounded Jobs
that verify native delivery scope and a second renewal reaching the mounted
file. The runner emits booleans and resource identifiers only. CronJob failures
and ExternalSecret Ready=False are the native degraded-state signals. A failed
renewal leaves the last verified token in custody; expiry causes authentication
to fail closed. Restore provider/custody connectivity and launch a renewal Job
from the CronJob; verify SecretSynced and repeat live acceptance.
Attended setup is reproducible through `openbao-attended-exec.py` with
`keycape_factor_metadata.py --apply --receipt <new-file>`,
`keycape_factor_bootstrap.py --receipt <new-file>` and
`keycape_factor_renewal_metadata.py --receipt <new-file>` in that order, followed
by the custody manifest and guarded `keycape_factor_activate.py --apply`.
Use unique receipt paths. Existing mismatched policies/roles/provenance fail
closed; never replace an unknown owner credential. The separate
`keycape_factor_eso_metadata.py` records the migration from initial read-only
metadata to ESO's self-session permissions; fresh setup uses the final policy.
Outstanding acceptance is explicit in RPF-WP-0040-T04: genuine provider JWT
expiry and provider-policy revocation/recovery drills. A newly issued JWT does
not itself revoke its predecessor. Native mounted rotation has passed, but it
is not evidence of predecessor revocation. Optional MFA rollout and lost-factor
recovery remain KEY-WP-0035 / USER-WP-0030, not completed by this service lane.

title: "Establish KeyCape factor credential custody and renewal"
domain: financials
repo: railiance-platform

owner: codex
topic_slug: financials
created: "2026-09-13"
updated: "2026-09-13"
---
User authorized establishing custody/delivery on 2026-09-13 and offered attended administrative authentication. Supports USER-WP-0030-T03 and KEY-WP-0035-T02. Existing incident lanes are not silently repurposed.
## Establish exact-path custody and workload delivery metadata
```task
id: RPF-WP-0040-T01
status: done
priority: high
```
New KV v2 path platform/workloads/net-kingdom/keycape-factor-read, field TOKEN, provider expiry metadata. Reader role binds only sso/keycape-factor-eso, audience openbao, exact-path read policy and fifteen-minute OpenBao tokens. Attended admin metadata apply, exact readback and capability checks. No wildcard secret access or secret value in output.
## Provision a bounded provider identity and renewable credential
```task
id: RPF-WP-0040-T02
status: done
priority: high
```
Create dedicated privacyIDEA keycape-factor-reader with coulomb tokenlist permission. Preserve existing admin rights; baseline has no admin policies. Store renewable issuer credential separately from the delivered JWT. Use protected stdin and in-memory handling, provider-issued JWT with expiry, positive cross-user scope and negative admin policy-read checks. No personal admin password in runtime.
## Activate and verify renewal and consumer delivery
```task
id: RPF-WP-0040-T03
status: done
priority: high
```
Deliver via namespace-scoped ESO, activate KeyCape adminTokenFile with byte-preserving config CAS, schedule renewal before expiry and verify mounted reload and native scope. Predecessor expiry/revocation and recovery drills remain T04. Verify effective scope and real factor acceptance before optional client policy. Preserve existing incident residuals in NK-WP-0033.
Live implementation and evidence: docs/evidence/2026-09-13-keycape-factor-custody.md.
Fourteen offline tests pass; native renewal, exact-path ESO delivery, negative
scope checks, provider per-user lookup and mounted rotation passed. KeyCape
rolled out Ready 1/1 without changing MFA policy or signing/client secrets.
## Verify provider expiry and revocation recovery
```task
id: RPF-WP-0040-T04
status: todo
priority: high
```
Exercise genuine JWT expiry, provider-side permission withdrawal and recovery
with an isolated fixture, preserving real users' factors and admin access.
Verify rejected predecessor handling independently of OpenBao token revocation.
Include provider interruption/retry evidence and maintain visible failed-Job /
ExternalSecret failure signals. This is remaining acceptance, not another owner
handoff. Historical resolver incident NK-WP-0033 remains separately open.
