Fable 5 is a new tier above Opus, priced at $10/MTok input and $50/MTok output (cache read $1.00, cache write $12.50). Without an entry it matched no pricing keyword, so calc_cost billed it at $0 and the dashboard dropped it from billable totals. - Add claude-fable-5 to the PRICING tables in cli.py and dashboard.py, plus a "fable" substring fallback for date-suffixed ids - Include fable in the dashboard billable filter and model sort, and in the scanner's session primary-model priority (above opus) - Update the README pricing table and keyword list - Add tests for the pricing entry, fallback, and priority ordering

What
Adds pricing for Claude Fable 5, the new tier above Opus.
Input and output rates are from the Fable 5 announcement. Cache rates follow the same multipliers every other row uses (read = input × 0.1, write = input × 1.25).
Why
Fable usage matches none of the existing pricing keywords, so
get_pricingreturnsNoneandcalc_costbills it at $0. The dashboard also drops it from billable totals. Tokens show up, but cost reads as $0 /n/a.Changes
cli.py/dashboard.py: aclaude-fable-5row in both PRICING tables, plus afablesubstring fallback so date-suffixed ids (e.g.claude-fable-5-20260601) resolve. The two tables stay in sync, which the existing sync test enforces.dashboard.py: fable now counts inisBillable, resolves ingetPricing, and sorts first inmodelPriorityas the top tier.scanner.py:MODEL_PRIORITYgainsfable: 4, so a session's primary model picks Fable over a subagent's Opus or Sonnet turn.README.md: pricing table row and the included-keywords sentence.test_cli.py, priority ordering intest_scanner.py. Suite is 107 passing.Same shape as the Opus 4.8 pricing PR, with the added
scanner.pypriority bump that a new model family needs.
