Expose local Claude Code CLI transcript usage in Settings so users can inspect recent token consumption and daily activity without leaving the desktop app.
The page uses server-side transcript aggregation for session, message, tool, model-token, and subagent token data. Daily token buckets use assistant message timestamps, and daily session counts use active parent sessions for the same date bucket so resumed sessions and cross-midnight work do not produce token-only days. Cache accounting is bumped to v5 to force recomputation under the corrected daily semantics.
Constraint: Usage data must come from local Claude Code CLI transcripts rather than mock/demo data.
Constraint: Desktop navigation keeps Token usage directly above Diagnostics.
Rejected: Bucket all token usage by session start date | hides resumed-session and cross-midnight consumption from the actual day it was spent.
Confidence: high
Scope-risk: moderate
Directive: Keep daily token and daily session counts on the same date-bucketing semantics.
Tested: bun run check:desktop
Tested: bun run check:server
Tested: Browser verification for Token usage in English and Chinese locale date labels
Not-tested: Full bun run verify quality gate
