docs: name where operator credentials live, and label unexercised procedures 
Three gaps from NK-WP-0033, none of them the fault we set out to fix.

Operator custody (platform-root-custody.md). This document named a
password-safe entry that had never been created, so the 2026-08-23
rotation had nowhere to put the new LLDAP admin value and the outgoing
one survived only in a browser entry that was overwritten on 2026-08-27.
Decided: operators/<subsystem>/<account> in OpenBao for everything
reachable once logged in, plus a short closed offline list for what you
need when OpenBao is not — platform-root's own password, unseal shares,
break-glass. Anything on that list in OpenBao would be circular;
anything not on it does not belong in the packet.

The rule that closes it: every rotation names, as a numbered step, where
the outgoing and incoming values go. NK-WP-0033-T04 rotated four classes
with no such step, and that is the root cause of the session that
followed — not the four software defects it also surfaced.

Secret disclosure by trust stage, tied to the existing S0-S6 table. A
fingerprint may be spoken to confirm two parties hold the same
credential; the whole value never may. Used ad hoc throughout 2026-08-27
and worth writing down.

Attended procedures (new standard). reconcile-lldap-resolver-live.sh was
approved, documented, revision-pinned and had never run; its first
execution found four defects, two of which meant it could never have
completed. verify-t06.sh passed throughout. An unexecuted procedure is
unfinished work and must say so in its runbook header.

KeyCape exposure: privacyIDEA resolver reconciliation

Incident: KEYCAPE-EXPOSURE-20260823-01
Workplan: NK-WP-0033
NetKingdom procedure: sso-mfa/k8s/privacyidea/reconcile-lldap-resolver-live.sh (repaired 2026-08-27 in 4a38511; the previously pinned revision could not complete a run — see NK-WP-0033 T05) Platform recovery contract: railiance-platform 453fed3
Owner cutover receipt: State Hub message 45b236c8-052f-43d3-a472-44f8e9694da2 Exercise status: exercised 2026-08-27 by Bernd Worsch — first run ever; four defects found and fixed (4a38511). See attended-procedure-standard.md.

This is the remaining attended provider-admin operation after the owner-reported four-class cutover. It updates only privacyIDEA resolver lldap-coulomb so the resolver uses the replacement LLDAP bind credential. It does not modify realms, policies, tokens, KeyCape Secrets, or any other resolver.

No password, hash, token, Secret payload, or manifest belongs in this document, State Hub, Git, chat, command arguments, or ordinary logs.

Authority and pinning gate

The operator must record a private approval receipt containing, at minimum:

  • incident KEYCAPE-EXPOSURE-20260823-01;
  • the NetKingdom revision containing reconcile-lldap-resolver-live.sh and platform contract 453fed3;
  • the owner receipt 45b236c8-052f-43d3-a472-44f8e9694da2;
  • the exact start/end window, attended driver, and independent abort operator;
  • confirmation that the replacement LLDAP credential is the provider-approved value and that no exposed predecessor will be restored.

No live action is permitted if any revision, owner, cluster, or approval identifier differs from the receipt.

Preflight (metadata and health only)

Run from the approved operator workstation, with the cluster context and provider endpoint already authorized. Do not render any Secret data.

  1. Verify the approved checkout contains reconcile-lldap-resolver-live.sh with mode 0755; inspect its source, not live credential material.
  2. Confirm LLDAP, privacyIDEA, KeyCape, Authelia, and identity-provisioner are Ready using deployment/pod status fields only.
  3. Confirm privacyIDEA availability via the documented unauthenticated /token/ probe (401/403 is expected) and KeyCape discovery health, discarding response bodies. Do not use a command that prints a bearer token or configuration response.
  4. Confirm the approved window, driver, abort operator, provider custody, and cleanup workspace are ready. Stop on any drift or missing owner.

Apply (one attended operation)

  1. From the approved checkout, run exactly:

    bash sso-mfa/k8s/privacyidea/reconcile-lldap-resolver-live.sh --apply

    The helper securely prompts for pi-admin, replacement and predecessor LLDAP passwords, and one approved MFA code; authenticates to privacyIDEA; performs exactly one POST /resolver/lldap-coulomb; proves replacement resolver lookup, privacyIDEA MFA, replacement LLDAP authentication, and predecessor denial; rechecks readiness/health; securely cleans up; and emits one sanitized PASS/FAIL receipt. It must not be combined with repair-realm-live.sh, bootstrap-realm.sh, creds-rotate.sh, or any full-bundle generator.

  2. Stop immediately on any non-success response, timeout, unexpected endpoint, or failed cleanup. Do not restore the exposed bundle or predecessor credential.

Postflight and predecessor denial

Record only status codes, readiness, timestamps, revision identifiers, and boolean results.

  1. Confirm privacyIDEA, LLDAP, KeyCape, Authelia, and identity-provisioner are Ready again. Confirm the privacyIDEA health endpoint succeeds and the resolver endpoint returns success without retaining its response body.
  2. Exercise one approved KeyCape MFA path that requires the coulomb realm. Record pass/fail only; never record the token or response body.
  3. Using protected file inputs, prove an LDAP bind with the replacement value succeeds and a bind with the exposed predecessor fails. The predecessor test must be a boolean result and must not put the password in argv or stdout. A failed predecessor bind is required evidence; do not retry it against another provider.
  4. Confirm the KeyCape owner’s existing four-class positive/negative receipt remains associated with this resolver update. If any class lacks a receipt, keep T05 open.
  5. Securely remove the temporary workspace and record only cleanup success.

Abort and rollback

Abort before mutation on revision drift, missing authority, unavailable health, uncertain workspace cleanup, or any unsafe helper output. Abort forward after mutation on a failed resolver response, failed readiness, failed replacement MFA, or missing predecessor denial. The exposed bundle and every exposed predecessor are never rollback material. Recovery after a partial write must use a newly approved replacement value and revision, not a stale local bundle.

Completion evidence

T03 may move to done only after the helper run and cleanup receipt are recorded by the attended operator. T05 may move to done only after the resolver’s replacement success, predecessor denial, owner cutover receipt, and all residual limitations are recorded as sanitized evidence.

Revision note — 2026-08-27

The pinned revision of reconcile-lldap-resolver-live.sh had never completed a run. Four defects were found by running it and are fixed in 4a38511; see NK-WP-0033 T05 for the full findings. Two change how this procedure is invoked:

  • --predecessor-unavailable — use when the exposed predecessor cannot be produced. The denial bind is not attempted and the receipt records predecessor denial=NOT-PROVEN. Do not type a placeholder at the predecessor prompt instead: a wrong value also fails the bind, and the run records it as a passing denial proof — a receipt asserting a test that never ran.
  • --note TEXT — operator context carried verbatim in the receipt line, so a claim and its caveat travel together. One line, 200 characters, no credentials.

TIMEOUT, CACHE_TIMEOUT and SIZELIMIT are now sent with the resolver body (default 5 / 120 / 500, overridable via the matching LDAP_* environment variables). Before this fix, --apply dropped them, because a resolver write replaces the whole object. A resolver with them unset still resolves users, but the WebUI refuses to save or test it — so a hand repair was silently reverted by the next run.
