 ## Outcome
 
-- Not completed.
+- Completed in the feature worktree. Implemented and composed the remaining Go
+  modules: administration and organization lifecycle, assets and hardened
+  storage/remote fetch, billing ledger/catalog/settlement, usage reporting,
+  jobs/providers/webhooks/worker loop, templates/prompt, settings/logging,
+  public and compatibility HTTP routes, localstore adapters, PostgreSQL
+  adapters, and lifecycle fencing migration 0002. Added language-neutral
+  contracts and executable TypeScript/Go consumers while preserving the
+  existing Next production ownership and deployment topology.
+
+- Added final lifecycle hardening for streamed HTTP event logging, unique
+  worker lease tokens and CAS fencing, commit-outcome reconciliation, retry
+  recovery handles, readiness checks for lifecycle columns, mock output
+  registration, usage filter options, public webhook/priority validation, and
+  a single settings/billing-account source.

 ## Promotion Candidates

+- Preserve the new Go module map and contract fixtures as candidates for the
