Outcome

Split along the architecture's boundaries into 3 coders: 9925 grid term and built-in cutover (Foundation), then 9926 SDK/ACP agent rows and 9927 Providers tab UI in parallel. Acceptance tightened: named refusals, readable 390px grid, no raw dev API edits (deferred to Finish). F1/F2 named, not filed. Memory: none applied.
