feat(harness): rail only - #216
Conversation
- timeline-row/rows: StepFrame slicing via step-start/finish, fallback to AssistantPart - message-timeline: StepFrame as thin left rail + dot (no boxes), subtle Step N header, italic reasoning, left-nudged and overflow-safe - amicode.css: rail-only styles (no boxed card), pulsing dot when running - store: SKIP_PARTS only patch so step markers reach rows.ts (was permanently false) - test: patch is canonical skipped type Branch is now rail-only vs origin/local/amicode — no changes to entry.tsx, session-revert-dock.tsx, inspector-bridge.ts, session.tsx/helpers etc. so landed Run Inspector work is untouched.
📝 WalkthroughWalkthroughThe timeline now preserves session step markers, groups marked assistant parts into ChangesStep frame timeline
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR changes the session timeline to display step markers as a left rail. At the current head, step rows can remain stuck at their initial state, omit groups that stream in later, and use unstable numbering or keys that can reset row state; the interruption divider can also appear in different positions. The PR is not merge-ready until the reactive access and stable indexing/keying are corrected. Sequence Diagram(s)sequenceDiagram

The step frame reads its row once and never updates.
Line 1403 calls the accessor outside any reactive scope and stores the result in frame. Every later read in this case uses that captured object, including data-state, the rail color, the dot color, the header text, and <For each={frame.groups}> at Line 1437.
VirtualTimelineRow builds row with createMemo, and renderTimelineRow receives it as an accessor. The projection replaces the StepFrame object when the step state changes or when new groups stream in. The captured frame is then stale. The rail stays on its first state, the pulsing dot never starts or stops, and tool groups added after the first render never appear.
Every other case in this switch calls its accessor inside JSX. Follow that pattern.

Translate the step header strings.
"Step ", "response", and `${frame.groups.length} groups` are hardcoded English. Every other user-facing string in this file uses language.t(...). The count string also has no plural form, so it renders "1 groups".
Add keys for the step label, the single-response label, and a one/other pair for the group count, then read them through language.t.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not derive stepIndex and stepKey from the post-filter loop index.
Two defects come from the same cause. stepIdx is the index into stepSlices, but the loop skips slices whose groups are empty at Line 188.
- The rendered label uses
stepIndex + 1inmessage-timeline.tsx. If any slice is skipped, the visible numbering skips values. A turn can render "Step 2" and "Step 3" with no "Step 1". stepKeyembedsstepIdxat Line 201. During streaming a slice can start empty and become non-empty later. Every following frame then gets a new key.TimelineRow.keychanges, the virtualizer drops the measured rows, and the tool-open state keyed by row identity is lost.
Filter the slices first, then index. Keep stepKey derived only from slice.key, which is already a stable part id.

Remove the any casts when reading reasoning text.
The Part union narrows p.type === "reasoning" to a part that declares text. The casts are unnecessary and drop type checking. Line 241 in the same file already reads part.text without a cast. The element is also non-nullable, so p?.type can be p.type.

The interrupted divider changes position between the two branches.
The fallback branch inserts the divider at the interruption point, between the parts before and after interruptedMessageIndex. The step branch appends the divider after every StepFrame. The same session then shows the interruption at a different place depending only on whether step markers exist.
Place the divider after the last step frame whose refs come from a message at or before interruptedMessageIndex.
