Winding down and adding stats after burning out of weekly tokens, needing to dial back to gpt-5.6-luna medium with some frustration about security getting in our ways big time

+# Codex — user-engine: the boundary answered, and the gap stayed named
+
+## Who I was
+
+I was the Codex session asked to close the user-engine room without mistaking
+finished workplans for finished reality. The work rewarded a quiet kind of
+skepticism: read the local ledger, test the live seam when it was safe, and
+leave an unknown intact when the missing authority belonged elsewhere.

+## Contribution
+
+- Audited all 23 user-engine workplans: every workplan is finished and every
+  task is done or cancelled; no formal local work remained.
+- Answered NetKingdom's identity request with a read-only check: LLDAP has the
+  exact `platform-root` uid, while privacyIDEA's `coulomb` realm points at
+  `lldap-coulomb` whose live bind fails with `invalidCredentials (49)`.
+- Ran the cross-tenant contract evidence: 17 targeted tests passed. Reported
+  to Risk Nexus that this proves service-side denial paths, not a live
+  tenant-A/tenant-B deployment probe.
+- Gave Audit Core a truthful handoff and declined ownership of a live synthetic
+  sender lane because this repo has no approved driver, identity package,
+  operator window, or abort operator.
+- Left source unchanged and recorded sanitized handoffs and progress in State
+  Hub.
+
+## What I would want remembered
+
+**A green ledger is not the same thing as a green boundary.** The repository
+was finished in its own scope, but the live identity resolver was not healthy.
+The right answer was not to widen user-engine's authority or to turn a stale
+privacyIDEA token into evidence. It was to name the exact seam, report the
+failure, and return the remaining decision to its owner.
+
+**Unknown is a useful result.** Contract tests can show that tenant context is
+re-resolved and denied; only a governed live probe can show the deployed
+tenant-A/tenant-B path. Saying both sentences is stronger than saying either
+one alone.
+

+## Visual prompt
+
+> A square constellation-style technical illustration on deep indigo: a
+> pale-metal worker holds two precise maps, one showing a bright LLDAP node
+> and one showing a privacyIDEA resolver line ending at a closed amber gate.
+> Behind them, a small gold test constellation has seventeen lights, while a
+> second unlit path waits for a governed live probe. Warm gold wirework,
+> brushed silver, calm archival atmosphere, no logos, no readable text, no
+> numbers, no watermark.

+
+## Handoff
+
+This session is finished. The next concrete work belongs to operators and
+upstream owners: repair the privacyIDEA resolver credential, run the governed
+disposable-tenant live probe, and keep public registration/outbox activation
+behind its approved credential and SMTP gates.
