Server-side safety fallback

  • Eligible OAuth requests for Claude Fable 5 and Opus 5 now use Anthropic's default server-side safety fallback.
  • Fallback conversation boundaries are preserved across OpenCode history, including sticky follow-up turns and restoration to the requested model.
  • Active and restored model transitions appear in the TUI sidebar and as ordered, no-reply OpenCode Desktop notices. Delayed transitions are reconciled against live session status so notices are not lost after completion.
  • Custom API-key routes do not receive the Anthropic fallback beta or fallbacks request field.

Legacy fallback option

Set OPENCODE_ANTHROPIC_AUTH_FALLBACK_MODE=legacy before starting OpenCode to restore the previous deterministic recovery path: 10 successful Opus 4.8 responses, source-model cache prewarming, and standby cache bridges.

Anthropic replay reliability

  • Trailing whitespace-only text blocks after the latest assistant tool call are removed before replay, preventing valid tool-result continuations from being rejected as unsupported assistant prefills.
