- 5 agent review-round bugs: cost model, approval crash, callback imbalance, stale context, dead code
- currentModel passed to provider.stream() so fallback model switch takes effect
- Consecutive same-role messages merged in Anthropic conversion
- Synchronous settled flag for pending task detection
- Provider-level retry removed to eliminate double retry
- HTTP 413 categorized as prompt_too_long
- termcanvas-hook.mjs moved to skills/scripts/ to match registered path
