1. wheel-down jumped to the bottom because max_scroll() derived the limit from
geometry, which only covers expandable blocks — a text-only conversation
left it at 0, so one down-notch clamped scroll to 0 with follow=true and
the next draw snapped to the real bottom. The limit now uses
content_lines (the full rendered line count, stored per draw).
2. tool request and result are now one block ('requested where it returns'):
UiBlock::ToolCall/ToolResult/ToolExec are unified into UiBlock::Tool, built
by merging each assistant tool call with its matching tool_result message
(looked up by call_id). Collapsed shows the concrete summary + duration +
status; expanded shows human-readable args, then '── 结果 ──', then the
output (two-level: partial preview with remaining-line hint, then full).
Live running executions reuse the same block. ToolResult messages are no
longer rendered standalone.
tests updated for the merged model; wheel test now drives content_lines.
The scroll offset semantics were inverted for the wheel and PageUp:
is the content offset (larger = newer), so scrolling up must DECREASE it, but
ScrollUp and PageUp both INCREASED it — every wheel event (either direction)
moved toward the bottom, and at the bottom (follow=true) an up-notch added 3
then got clamped back to max, making the wheel dead until keyboard-scrolling
away. Now:
- wheel ScrollUp/ScrollLeft: offset -1, follow cleared (works from the bottom)
- wheel ScrollDown/ScrollRight: offset +1, follow restored at the bottom
- PageUp: offset - view_height; PageDown: offset + view_height
- one line per wheel notch (was 3) for line-by-line scrolling
regression test drives handle_mouse with synthetic events (direction,
line-step, no underflow, follow transitions).
- ratatui + crossterm chat UI: streaming assistant text, multi-line input,
bottom status bar (model / protocol / session id / context usage)
- thinking blocks collapse to a summary with duration + estimated tokens;
tool calls collapse to a concrete summary (path / command) + duration;
click or Tab expands the details
- config modal (/config): provider, OpenAI protocol, baseUrl, apiKey, model,
contextWindow — persisted to ~/.focus/config.json; session list (/sessions)
on the harness JSONL tree; /new, /compact, /help
- auto-compaction (80% threshold, no confirmation) + dynamic system prompt
with usage info run in a background job (fake-provider-testable)
- Esc aborts a run (abandons the job thread; bounded by the provider timeout)
- tests: config codec, summaries/durations/wrap/caret, UI state machine with
an injected clock, job flow with a fake provider, session persistence
