Claude Code working line: rotating verb + turn tokens + elapsed timer next to the spark

[flazouh]

Owner request (2026-08-26): beside our Claude working-spark (our equivalent of 'Planning next moves'), show the famous Claude Code working line — a rotating gerund verb, the tokens received so far this turn, and a live elapsed timer. Reference shape: 'Puzzling… (12s · ↑ 1.4k tokens · esc to interrupt)'.

SCOPE

1. VERB: a rotating set of gerunds cycling every few seconds while the turn runs (Claude Code ships dozens: Puzzling, Pondering, Noodling, Simmering, Percolating, Ruminating…). Ours should feel native, not copied verbatim — a curated list plus a deterministic-but-varied rotation (seeded per turn so it does not flicker on re-render). Pairs with the existing claude-working-spark morph sprite; generic providers keep a neutral verb set.
2. TOKENS: per-turn token count, live. The data already exists as a contract fact — ClaudeSdkMap emits UsageFact { inputTokens, outputTokens, totalTokens, costUsd, contextWindowSize } and the adapter currently routes it into generic SessionMetaUpdated metadata (same swallow-pattern as provider_session before Session experience parity: make real Claude threads feel alive (spec + checklist) #262: the projector never reads it, so nothing downstream can show it). Needs: project usage per TURN (projection_turns or a usage projection), expose on the snapshot, render in the working line. Show received/output tokens for the running turn, formatted compactly (1.4k).
3. TIMER: elapsed since turn start, ticking ~1/s, from the canonical turn start (projection_turns.started_at) so it survives a reopen mid-turn.
4. INTERRUPT HINT: include the interrupt affordance text/binding consistent with our composer (we have an Interrupt control already).

NOTES

• Must degrade honestly: no fabricated token numbers — if usage has not arrived yet, show the verb and timer only.
• Blocked-on-approval state (Imported/discovered sessions have no provider — sends answered by the tracer, then hang on an unsurfaced approval #268) must take precedence over the verb line.
• Queued behind Imported/discovered sessions have no provider — sends answered by the tracer, then hang on an unsurfaced approval #268 (same status-mapper/scene-entry files).
