Drill: Clone Linear issue list: build, critique against real Linear, iterate. Log divergences.
Interpretation: Built the canonical Linear Engineering issue list — sidebar (workspace switcher, single-hue indigo project-dot ladder, views with mono counts) + filter chip toolbar + status-grouped rows (In Progress / In Review / Todo / Done / Cancelled) with 2px priority left-edge bars, conic-gradient status rings (amber/blue partial fills, dashed Todo, green Done check, strikethrough Cancelled), JetBrains Mono IDs, label pills, gradient-circle assignee avatars. Applied all accumulated calibration learnings from the start (0.8px conic ring border, weight 450 group headers, #e5484d urgent red, mobile title-above-meta anatomy, topbar breadcrumb cut, scroll+mask filter chips) so iteration 1 lands close to CALIBRATED.
