Context
T0.2 gate leaf of Epic #14560 (map v1.1), carrying the #13444 graduation's density AC down to the cockpit surface: "the UX epic needs actual count/density evidence before freezing layout." Filed under the operator-escalated decomposition sprint (D#14561).
The Problem
The SSOT artifact mocks 6–7 agents, ~5 stream events visible, 2-column grid. Tonight's live reality already stresses those assumptions: 12 registered identities, message bursts of 40–90 per 25-minute window (observed 2026-07-04, wake-batch sizes), 15+ tickets filed per hour during a sprint. A layout frozen against the mock's density will break at real fleet scale — the #13444 review named this class explicitly (scale-to-a-glance needs numbers, not vibes).
The Architectural Reality
Evidence sources, all queryable today: the Memory Core roster (who_is_online — registered vs active vs benched counts), A2A volume (message timestamps per window from list_messages paging), lifecycle event rates (PR/review/comment timelines from the synced content), lane counts (D#14561 claims ledger + open epic assignees). The temporal-pyramid L2 records (#14433 orbit) will eventually make this a query; this spike hand-collects once.
The Fix
A short evidence doc (comment on #14560 or apps/agentos/design/ sibling artifact — placement per #14577's decision): agent-count distribution (registered/active/concurrent), events-per-minute percentiles for the activity stream (median + burst), lanes-per-agent, and the derived layout consequences (grid columns at N agents, stream buffer + collapse thresholds, health-bar categories). Each number carries its query/source (the #14430 falsifying-query discipline applied to design inputs).
Acceptance Criteria
Out of Scope
- The views themselves (T2–T5 consume this).
- Temporal-pyramid automation (#14433 orbit — this is a one-shot hand collection).
