The brand re-theme (#235) carried the site's cream/olive palette into the dark variant as well as the light one. Cream reads as a deliberate warm surface on white; on a dark ground it reads as a colour cast, and next to the surrounding VS Code chrome the app looked like it belonged to a different product. Dark backgrounds, text, icons and borders return to the values they had before the re-theme (oc-2's neutral ramp) — greys 50-1200, the text and icon steps that ride on them, the legacy surface/text/border overrides, and palette.neutral/ink, which seed everything the overrides do not pin. The pre-paint literal and the terminal's default dark colours follow, so the first frame and the terminal surface match the app again. The brand is untouched: yellow accent (#FFE614) in every accent role, the semantic green/red/warning ramps, the status dots, the yellow selection fill, and the whole light variant stay exactly as merged. Verified by resolving both variants — every neutral background/text/border/icon token is now byte-identical to oc-2, and every remaining difference is an accent- or status-derived token.
Ports the vertical rail from the website's /amicode animation (harmoniqs-ai app/components/demo/parts.jsx, `Step`) into the real chat. Until now a five-step solve rendered as five unrelated collapsible rows; the shape of the work was invisible. Two decisions that look odd and are load-bearing. PER-ROW SEGMENTS, not a container spine. The timeline is virtualised (@tanstack/solid-virtual): every row is an absolutely-positioned box and consecutive rows share no ancestor but the total-height spacer, so border-left on a parent is structurally impossible. The site independently arrived at the same per-row approach, which is why this port is small. Segments meet because each row already owns the 12px pt-3 gap the segment spans. DONE IS DECIDED BY ADJACENCY — a step fills once a successor exists — not by that step's own tool lifecycle. Tools complete out of order and run in parallel, so asking each row "are you finished?" would let a filled dot sit above a hollow one and destroy the rail's grammar. Adjacency makes the sequence monotonic by construction, and it is exactly what the website does: a step flips filled no later than the moment the next one appears. Tested as an invariant at several turn lengths: exactly one dot is ever running, and it is always the tail. Hollow therefore means RUNNING, never "planned". Worth recording that the website does not preview future steps either — its scenes gate every entry on `t >= from` and filter the rest out, so an unstarted step is never in the DOM. I had assumed otherwise. Simulating all eight scenes at 10ms resolution: max simultaneous hollow dots = 1, the tail in 100% of frames. Showing the real path ahead needs a plan source — the score `stages:` list is the candidate, and is a separate step. A single-step turn draws nothing: one dot on its own reads as decoration. TimelineRow.AssistantPart gains lastAssistantPart and turnRunning to carry the two facts the rail needs.

Test constructMessageRows instead of a duplicate row model.
railState and turn reimplement the state derivation from rows.ts and ThoughtRail. A defect in the production derivation can leave these tests passing.
Build assistant-message fixtures, call Timeline.constructMessageRows, and assert the produced AssistantPart flags. Keep direct shouldRenderRail tests only for its own predicate behavior.
As per coding guidelines, **/*.{test,spec}.{ts,tsx}: Test actual implementation, do not duplicate logic into tests.

Extend non-first rail segments through the row gap.
Line 54 starts each non-first segment at the nested session-turn top. The outer row adds pt-3, so the segment starts 12px below the virtual row boundary. The prior segment ends above that gap. This creates a visible break between assistant steps.
Include the preceding row gap in non-first segment geometry, including the tail height, or position the rail in the padded outer frame.

Cream reads as a deliberate warm surface on white; on a dark ground it reads as a colour cast, and next to the surrounding VS Code chrome the app looked like it belonged to a different product.
