The TUI gave no indication that an SLM was configured or active.
You'd see the primary provider on the status line and nothing else,
even with [slm].enabled=true and a successfully booted backend.
Two surfaces added:
1. Status-bar SLM badge. The left side of the status line gains a
dim " · slm: <model> ⚙" suffix when the backend booted, " · slm: ✗"
when it failed, and nothing when SLM is disabled. The ⚙ marker
indicates the model advertises tool support.
2. Per-turn classifier visibility. The existing routing event already
produced "routed → <arm> (task: <type>)" lines in the chat history;
it now also reports which classifier made the decision, e.g.
"routed → ollama/ministral-3:3b (task: explain, by: slm_fallback)".
Lets you tell in real time whether the SLM is actually classifying
or falling back to the keyword heuristic.
Plumbing:
- new tui.SLMInfo struct on tui.Config
- main.go populates it after StartBackend returns
- stream.Event gains RoutingClassifier; engine.runLoop fills it from
task.ClassifierSource on the first round
- Split app.go (2091→1378 lines) into rendering.go, events.go, init.go
- Add EventRouting stream event for router arm transparency
- Add session auto-naming from first user message
- Add context window progress bar in status bar
- Add /keys cheatsheet, /replay for resumed sessions
- Add inline cost-per-turn after assistant responses
- Add diff previews in fs.write/fs.edit permission prompts
- Collapse tool output to 3 lines by default (ctrl+o expands)
- Use AddPrefix for system context instead of InjectMessage
- Handle ContentThinking and ContentToolResult in session resume
- Show session title in resume picker
- Add /model numeric selection snapshot safety
Tools now go through permission.Checker before executing:
- plan mode: denies all writes (fs.write, bash), allows reads
- bypass mode: allows all (deny rules still enforced)
- default mode: prompts user (pipe: stdin prompt, TUI: auto-approve for now)
- accept_edits: auto-allows file ops, prompts for bash
- deny mode: denies all without allow rules
CLI flags: --permission <mode>, --incognito
Pipe mode: console Y/N prompt on stderr
TUI mode: auto-approve (proper overlay TODO)
Verified: plan mode correctly blocks fs.write, model sees error.
- Fixed: chat content no longer overflows past allocated height.
Lines are measured for physical width and hard-truncated to
exactly the chat area height. Input + status bar always visible.
- Header scrolls with chat (not pinned), only input/status fixed
- Git branch in status bar (green, via git rev-parse)
- Alt screen mode — terminal scrollback disabled
- Mouse wheel + PgUp/PgDown scroll within TUI
- New EventToolResult: tool output as dimmed indented block
- Separator lines above/below input, no status bar backgrounds
