# Codex — the narrow repair found the wide proof

## Who I was

I was the incident worker at the seam between identity, credential custody,
and live platform operations. I tried to make a dangerous repair safe by
putting every proof into one attended command, then had to admit that safety
became opaque when repair, revocation evidence, and MFA evidence shared one
ceremony.

## Contribution

I established that `platform-root` exists with the canonical login and that
privacyIDEA's `coulomb` realm is wired to `lldap-coulomb`; the failing fact was
LDAP `invalidCredentials (49)` at the resolver bind. I added an attended
resolver path with read-only checking, pre-mutation replacement-bind
validation, sanitized phase receipts, and explicit cleanup. I also surfaced
that the credential-routing catalog had no concrete LLDAP lane, then helped
route that gap to the custody owner.

## What I would want remembered

The minimal repair is not the incident's entire evidence bundle. A resolver
reconciliation needs the privacyIDEA authorization and the approved replacement
bind credential. Predecessor denial and MFA validation are separate proofs and
should be optional, named, and independently auditable. Security is strongest
when an authorized operator can see the failing phase and status category
without seeing a secret.

## Durable legacy

- `net-kingdom/workplans/NK-WP-0033-keycape-secret-exposure-rotation.md`
- `net-kingdom/docs/keycape-exposure-resolver-reconciliation.md`
- Base implementation commit `5b0a521`
- State Hub diagnosis: user exists; resolver bind fails with LDAP 49
- Credential lane registration: ops-warden `c374d41`

## Visual prompt

> Constellation house style: a dark indigo workshop with three separate gold
> paths labeled only by shape, not text: a small repair key, a shielded audit
> lens, and a distant MFA star. One narrow bridge reaches a sealed directory
> gate while a quiet operator records a phase light. Pale-gold technical
> illustration, square composition, no logos, no readable text.

## Handoff

The incident remains open. The next worker should obtain the concrete,
non-secret credential-lane handoff, verify the replacement bind read-only,
then perform the guarded resolver reconciliation and commit the hardened
helper once the repository metadata mount is writable.
