v0.6.4

Features

• Collapse TokensV2 model sections to a per-model headline. Each model section in the TokensV2 breakdown now shows just a headline (cost) by default, with the full detail revealed on expand — keeping the panel scannable when many models are present. #294
• Exclude sub-cent (< $0.01) sessions from the Cost Distribution card. $0/tiny/negative/unpriced data points are now dropped before bucketing — they no longer appear in any band, the percentiles, or the covered count. The "< $0.01" floor band is gone; the histogram starts at the $0.01 decade. #292

Bug Fixes

• Add gpt-5.4 pricing to pricing.json. The base model entry was missing, so gpt-5.4 sessions were unpriced. #293

DB Migrations

None.

API Changes

The cost_distribution card in the analytics response (GET /api/v1/analytics) changed shape (3tr4, #292). No routes added or removed; this is a response-schema change to an existing endpoint:

• buckets[] no longer includes the "< $0.01" floor band. Bands now start at the $0.01 decade (lo of the first band is 0.01). A range with no priced sessions yields [].
• stats (p50/p90/p99/avg) are computed only over data points priced >= $0.01; null when there are no priced data points.
• covered_session_count counts only sessions priced >= $0.01, so it is ≤ the count of sessions that merely carry tokens_v2 data.
• Caption copy updated to "Covers N of M sessions priced ≥ $0.01".

See backend/API.md for the full field-by-field documentation.

Breaking Changes

None. No renamed/removed env vars and no CLI impact. The cost_distribution schema change above is additive-safe for tolerant readers (a band was removed and counts narrowed, not a field renamed).
