v0.11.1 — polish model migration to claude-sonnet-4-6

[0.11.1] - 2026-05-08

Changed

• Polish model rename: claude-sonnet-4-20250514 →
  claude-sonnet-4-6. Anthropic deprecated the dated alias
  with EOL 2026-06-15; the V2/V3 verification probes on
  2026-05-08 surfaced the deprecation warning. Migrating to
  the family alias matches attune-rag's existing
  ClaudeProvider.DEFAULT_MODEL and tracks Anthropic's
  recommended migration path. Affected:
  • polish.py:_POLISH_MODEL
    — drives every polish call (synchronous + batch).
  • doc_gen/config.py:DocGenConfig.model
    — drives attune-author docs generation.
• One-time cold cache after upgrade. _POLISH_MODEL
  participates in the polish cache key, so existing cached
  entries become orphaned (they remain on disk but never
  match the new key namespace). The first regen after
  upgrade is a cold-cache miss for every feature; subsequent
  regens behave normally. Existing 30-day TTL prune
  (polish._cache_prune)
  reaps orphaned entries automatically.

Added

• Mocked smoke test at tests/test_polish_smoke.py
  pinning the wire-level model name. Catches the next
  model-rename failure immediately, no API spend.

Notes

• Users who want to reclaim disk space immediately rather
  than waiting for the TTL prune can run
  attune-author cache clear post-upgrade. Optional —
  the cache shrinks automatically over 30 days.
