Agent architecture overhaul. MASON (the architect) becomes the sole brief author and decides what to build straight from the conversation — the keyword/signal gate and propose_initial_brief are gone. The sub-agents get crew names (REED / IRIS / SAGE / HUE / SCOUT / STERLING / MASON).
Shared activity log. Every agent records what it's doing so Mira stops contradicting or re-asking in-flight work.
No more double-ask. The conversational lane (Mira) is now the sole questioner; Atlas hands its needs to her.
Per-industry "what to gather". Mined 10k evaluated briefs into per-category gap profiles, surfacing the highest-leverage missing fields to the agent (+ set_service_category).
Search simplified. Removed the funnel stage — search is the user button only; server-side cancel of the discovery stream.
Prod bug. Removed MASON's token cap that was truncating and overwriting real briefs with empty sections. New number / short-text / file input widgets.
