Selected rows in the model/session/skills pickers and approval/clarify
prompts only changed from dim gray to cornsilk, which reads as low
contrast on lighter themes and LCDs (reported during TUI v2 blitz).
Switch the selected row to `inverse bold` with the brand accent color
across modelPicker, sessionPicker, skillsHub, and prompts so the
highlight is terminal-portable and unambiguous. Unselected rows stay
dim. Also extends the sessionPicker middle meta column (which was
always dim) to inherit the row's selection state.
Drops `lastUserAt` plumbing and the right-edge idle ticker. Matches the
claude-code / opencode convention: elapsed rides with the busy indicator
(spinner verb), nothing at idle.
- `turnStartedAt` driven by a useEffect on `ui.busy` — stamps on rising
edge, clears on falling edge. Covers agent turns and !shell alike.
- FaceTicker renders ` · {fmtDuration}` while busy; 1 s clock for the
counter, existing 2500 ms cycle for face/verb rotation.
- On busy → idle, if the block ran ≥ 1 s, emit a one-shot
`done in {fmtDuration}` sys line (≡ claude-code's `thought for Ns`).
Status bar ticker was too hot in peripheral vision. The moment the elapsed
value matters is when the prompt returns — so surface it there. Dim
`fmtDuration` next to the GoodVibesHeart, idle-only (hidden while busy),
so quick turns and active streaming stay quiet.
StatusRule now renders `{sinceLastMsg}/{sinceSession}` (e.g. `12s/3m 45s`)
when a user has submitted in the current session; falls back to the total
alone otherwise. Wires `lastUserAt` through the state/session lifecycle:
- useSubmission stamps `setLastUserAt(Date.now())` on send
- useSessionLifecycle nulls it in reset/resetVisibleHistory
- /branch slash nulls it on fork
- turnController gates scheduleStreaming / reasoning recorders on
streaming + showReasoning so disabling them keeps the buffer silent
until message.complete flushes
- createGatewayEventHandler only surfaces inline_diff previews when
inlineDiffs is on
- StatusRule takes a showCost prop and renders `· $X.XXXX` with the
same toFixed(4) formatting as /usage when usage.cost_usd is present
- Usage grows cost_usd?: number to match the gateway payload
- Existing handler tests flip showReasoning on in beforeEach so
reasoning-flow assertions keep their meaning
Sticky prompt:
The loop was skipping `first` (the first row in the viewport) when
looking for a user message scrolled above the top edge. If `first`
itself was a user row that had just ticked above the viewport, we'd
fall through the early-return guard (`role === 'user' && !above`),
then walk from `first - 1` backward — never rechecking `first`, never
finding anything, returning '' and leaving the sticky empty. This is
why it felt "stuck" at the start: one-turn sessions with the user row
exactly at/near the top never surfaced the breadcrumb.
Collapsed the two branches into one loop starting at `first`: nearest
user wins — still-on-screen → empty (redundant to echo), already
above → text. Same semantics, covers the gap.
Scrollbar:
`useSyncExternalStore` snapshot was `scrollTop:vp:scrollHeight` —
scrollHeight ticks up by ~1 row on every streamed chunk, forcing a
re-render per chunk. Quantized snapshot to the displayed values
(`thumbTop:thumbSize:vp`) so we only re-render when the bar actually
changes. Drops render count per turn by ~100x during streaming and
stops the "constantly resizes" flicker.
The status bar was showing stale lifecycle text ("running…") while the
face+verb stream flickered through the thinking panel as Python pushed
thinking.delta events. That's backwards — the face ticker is the
primary "I'm alive" signal, it belongs in the status bar; the thinking
panel is for substantive reasoning and tool activity.
Status bar now reads `ui.busy`: when true, renders a local `<FaceTicker>`
cycling FACES × VERBS on a 2.5s interval, unaffected by server events.
When false, the bar shows the actual status string (ready, starting
agent…, interrupted, etc.).
Side effect: `scheduleThinkingStatus` still patches `ui.status` with
Python's face text, but while busy the bar ignores that string and uses
the ticker instead. No server-side changes needed — Python keeps
emitting thinking.delta as a liveness heartbeat, the TUI just doesn't
let it fight the status bar.
Hoist turn state from a 286-line hook into $turnState atom + turnController
singleton. createGatewayEventHandler becomes a typed dispatch over the
controller; its ctx shrinks from 30 fields to 5. Event-handler refs and 16
threaded actions are gone.
Fold three createSlash*Handler factories into a data-driven SlashCommand[]
registry under slash/commands/{core,session,ops}.ts. Aliases are data;
findSlashCommand does name+alias lookup. Shared guarded/guardedErr combinator
in slash/guarded.ts.
Split constants.ts + app/helpers.ts into config/ (timing/limits/env),
content/ (faces/placeholders/hotkeys/verbs/charms/fortunes), domain/ (roles/
details/messages/paths/slash/viewport/usage), protocol/ (interpolation/paste).
Type every RPC response in gatewayTypes.ts (26 new interfaces); drop all
`(r: any)` across slash + main app.
Shrink useMainApp from 1216 -> 646 lines by extracting useSessionLifecycle,
useSubmission, useConfigSync. Add <Fg> themed primitive and strip ~50
`as any` color casts.
Tests: 50 passing. Build + type-check clean.
