Component under test: the 100px tape docked at the bottom (boundary line + tag). Legend (kept out of the component): top hairline = context pressure (green→amber→red, purple nick = fold) · ◆ green diamonds = user prompts U1–U7 on a permanent lane — they never collapse; click one to jump the transcript to that exact prompt · token row = actors in order of appearance (pulsing = running, dim = done, red = failed; tiny arcs = spawn/trigger) · ribbon = episodes (hatched amber = in flight; red = cascade; ▾ red = failure; ▾ orange = watch fire; dashed purple cut = compaction) · bottom chips = the live why-now fuse (what triggered the current action).
