T06: optimization-case schema, fail-closed evaluator, cadence and decision template. Every option including the baseline must present all ten decision fields; one unknown blocks the comparison. Validated on the storage case (Hetzner computes and loses to Scaleway by EUR 29.14/month on operator labour; Host Europe blocks on four named gaps) and on the non-storage reef-railiance k3s rightsizing case (low utilization is real, but nothing is costable while the railiance01 price is unknown). T07: portfolio report over coverage, lifecycle, utilization, cost, renewals, risks, open cases, and next actions, derived only from committed evidence. Portfolio spend is reported null rather than as a partial sum, unattributed cost is a named list rather than a spread, and unmeasurable resources are reported rather than dropped. RESOURCE-WP-0003 is finished; both cases remain blocked_on_evidence against live delegated records in other repositories. RESOURCE-WP-0002 is untouched.
