v1.6.6

Multi-adapter orchestration

Bernstein now runs with any combination of CLI agents — no Claude Code dependency required. Configure per-role adapters in bernstein.yaml:

role_model_policy:
  backend:
    cli: qwen
    model: qwen3.6-plus
  security:
    cli: gemini
    model: gemini-3.1-pro-preview

The internal scheduler LLM also accepts any adapter (internal_llm_provider: gemini).

20 critical orchestration bug fixes

Deep audit found and fixed 20 severe bugs across the tick pipeline:

• Merge serialization — concurrent merges no longer corrupt the git index
• Completion ordering — worktree cleanup now happens AFTER PR creation (40+ tasks had work silently lost)
• Quality gate timeouts — timed-out required gates now block the merge instead of silently passing
• Auto-format race — runs sequentially before parallel gates, not concurrently
• Agent lifecycle — zombie agents tracked immediately after spawn, claimed tasks released on failure
• Push retry queue — failed pushes are retried on subsequent ticks instead of being silently lost

Proactive agent resilience

• Scope-aware budget — $2/$5/$15 per task scope instead of hardcoded $5, doubles on retry
• Scope-aware max_turns — large tasks get 2x more turns than small tasks
• Git health pre-check — stale index.lock files removed before worktree creation
• Completion instructions in system prompt — survive context truncation

Adapter improvements

• Qwen adapter maps all model aliases to real API IDs (coder-model → qwen3.6-plus)
• Gemini adapter uses OAuth without requiring API keys
• Router bypassed when explicit cli + model configured per role

Other
