/**
 * Dispatch-trace BRAIN hook.
 *
 * Emits a structured {@link DispatchTrace} observation into the BRAIN memory
 * pipeline at the agent-resolver decision point. Each trace captures the
 * classifier's prediction alongside the registry outcome, enabling future
 * training data extraction for the FP peer-note guardrail.
 *
 * Storage contract:
 * - Routes through `verifyAndStore` — never bypasses the extraction gate.
 * - `memoryType = 'pattern'` — procedural knowledge about dispatch behaviour.
 * - `sourceConfidence = 'speculative'` — unverified tier-2 training candidate
 *   until a ground-truth channel is added.
 * - Errors are swallowed (fire-and-forget) so the synchronous resolver path
 *   is never blocked or disrupted by BRAIN write failures.
 *
 * @module dispatch-trace
 * @task T1325

 * noise when BRAIN is unavailable.
 *
 * @param projectRoot - Absolute path to the project root (for `brain.db` access).
 * @param trace       - The resolved dispatch trace to persist.
