`scripts/lib/cost-estimate.js` carries a second, independent copy of the rate table that `scripts/hooks/cost-tracker.js` had, with the same defect: every `opus` model priced at $15/$75, which are Claude 3 Opus era rates. Opus 4.5 and later bill at $5/$25, so every current-generation Opus estimate was exactly 3x real spend. Two more errors in the same table: `haiku` was $0.80/$4.00, which is Claude 3.5 Haiku rather than Haiku 4.5's $1/$5; and Fable and Mythos had no bucket at all, so they fell through to `sonnet` and were understated 3.3x. Legacy buckets are added rather than overwriting, so correcting the current generation does not reprice the old one. `opusLegacy` keeps $15/$75 for the three models that really billed it (Claude 3 Opus, Opus 4.0, Opus 4.1) and `haikuLegacy` keeps $0.80/$4.00 for Claude 3.5 Haiku. The matching regexes are the ones already used by the cost tracker, so the two tables now agree on which model is legacy. Opus 4.0's snapshot is `claude-opus-4-20250514` with no minor segment, which is why the bare `opus-4-<date>` form is matched separately: an `opus-4-0` substring alone misses it. `skills/cost-aware-llm-pipeline/SKILL.md` and its zh-CN and ja-JP translations published the same stale numbers as prose. The Relative Cost column is derived from the rates, so it is corrected with them: against a corrected Haiku 4.5 baseline the multiples are now exact, which is why the approximation markers are dropped. `RATE_TABLE` keeps its existing keys and shape, so the export stays backward compatible. Tests: the existing test pinned the stale values and was updated to pin the correct ones. Coverage is added for each legacy spelling (alias, dated snapshot, Vertex `@` form, Bedrock prefix), for the current Opus line, and for the Fable and Mythos bucket.
