An assistant turn is now ONE ordered parts[] (text/reasoning/tool) instead of a
flat string, so tool calls render INLINE between text blocks rather than dumped
as separate rows below (spec §7 — the "dump-below" bug opencode's sync-v2 avoids).
- logic/store.ts: Part discriminated union + reducer rework. message.delta
appends to the open text part (or opens one); tool.start pushes a running tool
part; tool.complete matches by tool_id and updates that part IN PLACE (state,
envelope-stripped resultText, summary, error, lineCount); reasoning.delta
accumulates a reasoning part. User/system rows stay flat text; settled/resumed
assistant rows fall back to text.
- logic/toolOutput.ts: ported pure helpers — stripToolEnvelope (unwrap
{output,exit_code}, append [exit N]/[error] suffix) + collapseToolOutput +
truncate.
- view/messageLine.tsx: <For>+<Switch> dispatch by part.type with stable id keys.
- view/toolPart.tsx: two-tier render — inline one-liner (≤1 output line) or a
capped left-bar block (TOOL_MAX_LINES, "… +N more", click-to-expand) keyed off
the theme; reactive width via useTerminalDimensions.
Verified: bun run check green (23 tests / 5 files / 64 expects) — store
interleave/in-place/reasoning, a frame test asserting the tool renders inline +
envelope stripped, and toolOutput unit tests. Live tmux: a terminal-tool prompt
rendered "⚡ terminal" with its alpha/beta output inline between the assistant's
text parts; Ctrl+C clean, no orphan. Smoke P2b + parity matrix updated. Native
<markdown> for text parts is the next slice (2b-ii).
Turns the read-only Phase-1 view into an interactive shell, split into focused
view components (spec v4 §2 layout):
- view/transcript.tsx: ONE full-height <scrollbox> with a reactive <For>
(opencode's no-scrollback model). Applies the §8 #2 gotchas exactly:
minHeight:0 on the wrapper AND the scrollbox, NO flexDirection on the
scrollbox root, stickyScroll + stickyStart="bottom".
- view/composer.tsx: a native <textarea> captured by ref — flexShrink:0,
focus-on-mount, Enter->submit via keyBindings, imperative .clear() on submit,
and a `submitting` re-entrancy guard. Wired by the entry to fire prompt.submit
(Effect.runFork on the in-hand service value); it's now the PRIMARY input, with
the HERMES_TUI_PROMPT stand-in kept only for launch-with-prompt.
- view/header.tsx + view/messageLine.tsx: extracted, themed (no hardcoded
styles). MessageLine stays flat-text this slice; ordered parts (§7) land in 2b.
test/lib/render.ts now flushes 3 renderOnce passes before capture — a <scrollbox>
needs more than one pass to measure content + apply sticky, else the transcript
row paints blank.
Verified: bun run check green (12 tests / 4 files / 31 expects). Live tmux drive:
typed into the composer -> cleared -> user row -> streamed reply ("Here are three
words"); Ctrl+C quits cleanly even with the textarea focused, no orphan child.
Composer placeholder rendered the live skin's welcome string (skin->theme live).
Smoke P2a + parity matrix updated. Phase 2b (ordered parts/tool render/markdown)
is the next slice.
GatewayService/liveGateway over the real Python tui_gateway: JSON-RPC stdio
framing (Bun.spawn), 16ms event coalescing flushed inside Solid batch(), typed
GatewayError, and a decode-once GatewayEvent Schema (~35-member tagged union;
unknown/malformed events skip via Option.none, never crash the stream).
The Solid sync-v2-style store grows to: streaming text concat (prefer
payload.text), gateway.ready{skin}/skin.changed -> fromSkin reactive re-theme,
LRU id-dedup, and hydrate-while-buffering (resume scaffold). Theming is a 1:1
port of Ink's theme.ts (DARK/LIGHT, detectLightMode, ANSI-256 normalization,
fromSkin) behind a Solid ThemeProvider so existing skins work unchanged and the
view carries NO hardcoded styles. A console-safe diagnostics log (in-memory
ring + NDJSON file) is the single logging path.
Entry gains a live launch path (default; HERMES_TUI_FAKE=1 -> scripted hello)
with an initial-prompt bootstrap (session.create -> prompt.submit) as the
Phase-2-composer stand-in, plus a minimal Ctrl+C graceful quit
(renderer.destroy -> shutdown Deferred -> scope finalizers -> client.stop) so
the engine reaps its own gateway child instead of orphaning it.
Verified: bun run check green (tsc + eslint + 12 tests / 4 files); live tmux
drive connect -> gateway.ready -> prompt -> streamed reply ("pong") -> clean
teardown with no orphan bun/python. Parity matrix + smoke P1 run log updated.
