One quiet row beneath the composer/question shell (not flush to the screen bottom; static height, outside the morphing shell): - LEFT: context window + session cost, clickable → per-turn detail popover (context, total, unpriced count, one row per turn with model/steps/cost). All folds from core/prices.ts — sessionCost, contextWindow, turnCost — no cost math in components. - RIGHT: model + "Thinking —" — a placeholder slot for the coming model/thinking-level CONTROL (later work with its contract changes); display-only today, model read from the last turn's usage, pretty-printed (Glm 5.3 Flash). - Data: the record's turns log, seeded on mount, refreshed when the local stream settles, kept fresh by the existing record re-syncs. No turns yet → "—" everywhere; unpriceable turns never fold into a fake $0 (the doctrine). - formatUsd/formatTokens moved to components/usage-format.ts (shared with the activity dock); prettyModel joins them, pure + tested.

/**
|
||
* THE ACTIVITY DOCK (wave 4, vision observability): the bottom-right corner
|
||
* of EVERY view, one blob per running BACKGROUND process — session sub-agents
|
||
* (research/demo/visual) and global extraction runs. Teaching turns are
|
||
* deliberately NOT here: the dock exists to give background processes the
|
||
* observability the learner can't otherwise see; an in-flight teaching turn
|
||
* is fully visible where it happens (user decision, 2026-09).
|
||
*
|
||
* Data: ONE poll of GET /api/activity (jobs across ALL chats, title-joined,
|
||
* oldest-first + extraction runs), folded client-side with core/prices.ts.
|
||
* Cost is INFERRED (jobCost); the context line is the LAST model call's
|
||
* input+output against the model's limit (JobUsage.lastStep — pending
|
||
* contract) — never a cumulative sum, which would be the wrong number.
|
||
* Absent data renders "—", never zero (the doctrine).
|
||
*
|
||
* Quiet/ambient by design: no entry animations, stable keys, updates land
|
||
* in place — polling never flickers. Idle (no jobs, no extractions) renders
|
||
* NOTHING. Narrow viewports collapse to a count badge → click opens the
|
||
* drawer. Per blob: kind icon, elapsed, cost, context, activity line, and an
|
||
* explicit END button (POST /api/activity/abort — the backend lands with the
|
||
* agents stream; failures degrade to an inline "not available yet", never a
|
||
* dead control).
