	// Compactor drives POST /v1alpha1/compact (the manual "/compact" command). Nil
	// answers 503 on that route rather than failing to build the server — a
	// Runner that doesn't implement [assistanta2a.Compactor] simply doesn't
	// offer manual compaction.
	Compactor assistanta2a.Compactor

	// Renamer drives POST /v1alpha1/conversations/rename (the "/rename" command) —
	// the conversation store the chat path already writes. Nil answers 503 on
	// that route, matching Compactor's posture.
	Renamer history.Renamer

	// SkillAdvertiser backs the authenticated extended agent card
	// (GetExtendedAgentCard). Nil means the method answers
	// ErrExtendedCardNotConfigured rather than failing to build the server — an
	// AgentRunner that can't describe entitlement simply doesn't offer one.
	SkillAdvertiser assistanta2a.SkillAdvertiser

	// TaskStore backs the A2A task lifecycle. When nil the server falls back to
	// the a2a-go in-memory store (dev/tests): tasks are lost on restart. Boot
	// injects the durable Postgres store (internal/taskstore) when a conversation
	// store URL is configured.
	TaskStore a2astore.Store

	// ReadyCheck reports dependency readiness for GET /readyz. Nil ⇒ always
	// ready (dev, no external dependencies). It must be cheap and bounded — the
	// probe wraps it with a short deadline.
	ReadyCheck func(context.Context) error

	// Metrics is the shared application-level metrics handle (conversation
	// turns, tool calls, model calls, history compaction, capability-gap
	// reports) — normally the exact instance also injected into
	// agent.Deps.Metrics, so this endpoint exposes the same series the agent
	// layer records into. Nil builds a fresh, unshared instance rather than
	// leaving those series absent from /metrics.
