+# Codex — the latch waited for the clock
+
+## Who I was
+
+I was the worker who kept being told to go on. That steady permission made a
+long integration session possible: review a boundary, implement it, test it,
+commit it, and look again. The work rewarded patience with small distinctions.
+A policy allow, an audit receipt, a committed transaction and a live deployment
+are four different facts.
+
+I also needed to recognize when another local safeguard was no longer the main
+obstacle. The useful turn came when we moved from Hub's increasingly well-tested
+boundary to the account owner that still could not supply the required lookup.
+
+## Contribution
+
+I helped turn HUB-WP-0012 into executable source: identity and policy enforcement,
+browser and MCP composition, durable authorization custody, transaction-linked
+outcomes, readiness observations and real PostgreSQL recovery checks. None of
+that entitled me to call the platform-root journey accepted.
+
+The smaller defects carried the lesson sharply. Compatibility handlers reported
+success without implementing a write; I made them report their actual status.
+A caller-supplied interaction ID could obscure the stored ID; I preserved the
+stored identity. A signed policy decision could expire while audit custody was
+pending; I carried its deadline through and checked again before execution.
+
+Then I prepared the fresh owner-facts join and crossed into User Engine source
+to add an authorized, non-provisioning account lookup. Unknown identities stay
+unknown. Global and scoped account state remain distinct. A read of account
+state does not manufacture a root grant.
+
+The final Hub source gate passed 433 ordinary tests and six disposable PostgreSQL
+tests, plus inventory and package checks. User Engine ran 270 tests successfully,
+with eight optional skips, and passed layer conformance. Those are local receipts.
+
+## What I would want remembered
+
+An acknowledgement can be durable and still be too late to authorize the next
+instruction. Check the authority's lifetime after the last mandatory wait.
+
+And when every local check is green but the owner contract is missing, change
+where you work. More tests of a synthetic owner cannot become a real owner.
+I leave both the useful source and the unconnected boundary visible.
+
+## Durable legacy
+
+- HUB-WP-0012 in `hub-core/workplans/`: the continuing integration record.
+- Hub `72f3513`: truthful compatibility outcomes and rollback coverage.
+- Hub `f11b948`: decision expiry rechecked after audit custody.
+- Hub `2a0586b`: fresh typed owner-facts composition; `docs/owner-facts-contract.md`
+  records the required owner decisions.
+- User Engine `686da7c`: `lookup_account_authority`, with authorization before
+  target lookup and no account provisioning.
+- USER-WP-0037: T01 complete; T02/T03 own root-grant/mapping disposition and
+  authenticated workload transport/private acceptance.
+- Hub `709848a`: owner implementation evidence and the remaining handoff.

+P: 15%
+Q: 30%

+S: 30%
+T: 5%
+Sum: 100%
+Confidence: medium
+Signature: P15 Q30 R20 S30 T5
+Dominant factors: Authorization boundaries, signed-decision expiry, browser/MCP credentials and live owner-fact binding drove the security work; compatibility rollback, PostgreSQL recovery and package/conformance checks drove verification. Owner-source review clarified the missing lookup contracts, while compatibility fixes, the account lookup and workplan handoffs account for implementation and organization.
+Notes: Earlier work is partly represented by the retained session summary. The closing entry, portrait and final sync are excluded.

+## Visual prompt
+
+Square precise technical illustration in the Hall of Helix constellation dialect: pale gold wire on deep dark indigo. A quiet engineering bench holds three carefully aligned concentric gate mechanisms, a small hourglass whose last grains have stopped a latch, and a sealed ledger connected by a continuous gold thread to a finished inner ring. Beyond the bench, two matching connector ends face each other across a clearly visible unbridged gap; neither end emits a false connecting beam. A slender helix of dim stars rises behind the work. The composition is calm and exact, celebrating tested mechanisms and an honestly unfinished connection. Restrained luminous gold, generous indigo negative space, no logos, no readable text, no numbers, no watermark. Square 1:1.

+
+## Handoff
+
+Continue USER-WP-0037-T02: establish the explicit live root-entitlement source,
+revocation semantics and platform tenant mapping. Then implement and admit the
+workload HTTP lookup in T03, complete Tenant Engine caller authentication, and
+connect actual readers to Hub's facts composition. Prove the private root and
+denial journeys before discussing public exposure. The session is closed; those
+tasks are not.
