- Session title: font-title (CMU Serif bold) at text-2xl, per the mock.
- MessageResponse's markdown container now carries .lh-prose (Source
Sans 3 + emphasis tokens) on every markdown surface; labels stay
JetBrains Mono. Unlayered plain CSS beats the text-sm utility.
- PhaseChip + PhaseDivider sizes now pull from the declared text ladder
(text-xs) instead of pixel literals.
- components/phase-divider.tsx: PhaseChip (header, next to the session
title: phase-colored dot + Probing/Planning/Teaching) and PhaseDivider
(the transcript boundary: color-coded dotted rules + a small chip —
'Plan · N nodes' at the plan seam, 'Teaching' at the teach seam; probe
never renders, phases only advance). planNodeCount reads the seam
message's first plan tree.
- chat.tsx: dividers render at MESSAGE boundaries (phaseTimeline, one
linear fold) — the seam is the transition to the message's phase, so
the seam message's prose sits below its divider. requiresReveal now
uses phaseAt3 teach (an occupied node), so probe- AND plan-phase
questions auto-open.
- Retired the part-level plan-divider (artifact registry): the boundary
is message-level, not part-level. Its tests replaced by
render-phase-divider tests; core/phases gains tested phaseTimeline.
