Algis DumbrisandClaude Opus 4.6 8df22457ab feat: trust scores, claim semantics, state-change webhooks (011-trust-claims-triggers)
Trust scores: per (agent, action_type) pair, stored in agent_trust
table. Auto-adjusts when human reacts to AI agent messages (approve
+0.05, reject -0.1). Scores clamped [0.0, 1.0]. MCP get_trust action
+ REST API /api/trust/{agent}. Web UI shows trust progress bars on
agent detail pages.

Claim semantics: only one in_progress reaction per message enforced.
First agent to claim wins, duplicates rejected with clear error.

State-change webhooks: StateChangeNotifier interface fires
workflow.state_changed events through existing webhook infrastructure
when reactions change a message's derived workflow state.

Channel thresholds: publish_threshold and approve_threshold fields
on channels for configuring autonomy gates.

Migration 014_trust_claims.sql. 17 new test cases across trust
model + store.
