Set CARGO_TARGET_DIR to main repo's target/ for all spawned agents so worktree builds reuse the existing compilation cache instead of building from scratch. Also detect sccache and set RUSTC_WRAPPER for cross-worktree content-addressed caching. Without this, each worktree agent triggered a full cargo build from zero (30+ minutes) because git worktrees get empty target/. Co-Authored-By: Terraphim AI <noreply@terraphim.ai>
Circuit breakers now keyed by provider:model (e.g., anthropic:claude-opus-4-6) instead of just provider name. If opus is down but sonnet works, only opus is marked unhealthy -- anthropic provider stays healthy. Added: model_health(), is_model_healthy(), record_model_success(), record_model_failure() for per-model operations. provider_health() and is_healthy() still work at aggregate level: provider is healthy if ANY of its models is healthy. unhealthy_providers() reports a provider only if ALL its models are down. Fixes HIGH finding from compound-review #413. Co-Authored-By: Terraphim AI <noreply@terraphim.ai>

…able agents in context - Fix AgentRunRecord construction: extract chain fields from active_agents via .get() instead of referencing non-existent local variable - Add mention_parent_agent field to ManagedAgent, set at all 3 dispatch sites - Pass available_agents in MentionContextArgs so spawned agents know who they can chain to - Add 2 tests for available_agents in mention context output Refs #763 Refs #764 Refs #144
