- Around line 61-64: Align the ThoughtRail comments with the current
shouldRenderRail behavior: document that completed one-step turns do not render
the rail, and clarify that a lone first-and-last segment has a tail for running
steps but remains zero-height otherwise. Do not change rendering logic unless
the filled-dot behavior is explicitly required.

fd54773Compare…h dots Lone Thinking is first+last+running with a single dot. Both dangles (dot→bottom and 0→dot) leave one open end — every spine must end AT a dot at both ends, so a single dot has no line. Widget lab showed the cap still reads as line starting at thin air. Revert to 0px (PR 242) for lone, keep multi-step caps/bridges. Update Rule 6 docs.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Render the lone-running segment below the dot.
TimelineRowFrame passes first=true, last=true, and running=true for the pre-AssistantPart Thinking row. The current branch draws from the row top to the dot centre, so it leaves no segment from the dot centre to the row bottom. The rail therefore cannot connect continuously to the first AssistantPart.
Use top: \${dotCentre}px`andbottom: "0px"` for this branch. Update the related running-geometry comments to describe the same direction.
Proposed fix
- ? // lone thinking — Claude-like: line ends AT the blinking dot- { top: "0px", height: `${dotCentre}px` }+ ? // lone thinking — line starts at the dot centre and continues to the row bottom+ { top: `${dotCentre}px`, bottom: "0px" }📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Follow-up to #242.
What: PR #242 made the lone Thinking dot 0px (floating) so completion was dot-fills with no retraction. That reads as disconnected while thinking — the opening's longest phase shows a yellow dot with no spine, and the 1px overlap fix never applies to a 0px segment.
Fix:
ThoughtRailnow treatsfirst && last && running(the Thinking row before any AssistantPart) as a tail fromdotCentre(11px) to row bottom instead ofheight:0. The dot stays hollow + breathing (isRunning = last && runningstill true, so--accent/--accent-edge+thought-rail-breathe1.8s), and the spine is continuous into the first AssistantPart'sdotCentrecap. Non-lone tails/mids unchanged (caps at dot centre,NEG_STEP_GAP -1pxbridging).Closes follow-up on harmoniqs/amicode#542 thinking-state report.
