priceForModel prefix-matched every claude-opus-4* id to $75/M output — the legacy Claude 3 Opus rate. Opus 4.5–4.8 is $25/M (rate card held since 4.5), so /caveman-stats overstated the savings figure ~3x on any current-Opus session. Split the price table into legacy (4.0/4.1 + dated ids → $75) and current (4.5–4.8 → $25) prefixes, most-specific-first so existing dated-id behavior is preserved. Also corrects Haiku 4.5 to $5/M (was $4). caveman-stats suite stays green (29/29). The 4 pre-existing opencode installer failures are unrelated to this change.

Fixes #465.
Problem
src/hooks/caveman-stats.jspriceForModel()prefix-matches everyclaude-opus-4*id to $75/M output — the legacy Claude 3 Opus rate. Anthropic's Opus rate card has been $5/M in, $25/M out since Opus 4.5 (4.8 shipped on the same card, 2026-05-28). So/caveman-statsoverstates the savings/cost figure ~3× for anyone running a current Opus model — increasingly the default.claude-haiku-4was also stale ($4 vs Haiku 4.5's $5/M).Fix
Split the table into legacy vs current Opus, most-specific prefixes first (the loop returns the first match), so retired 4.0/4.1 (incl. dated ids like
claude-opus-4-20250514) keep $75 while 4.5–4.8 resolve to $25:This keeps the existing dated-id test (
claude-opus-4-20250101 → 75) valid instead of regressing it — preferred over a flat constant flip, which is the alternative I floated in #465.Tests
tests/test_caveman_stats.jsupdated and green — 29/29. Added asserts pinning both eras (claude-opus-4-8 → 25,claude-opus-4-1-20250805 → 75).Source: https://platform.claude.com/docs/en/about-claude/pricing
