Route A unblock + the first Route A code increment.
- U9 verdict recorded (plan OQ1 + docs/acp-contract.md): in an authenticated
interactive session the pinned claude-code-cli-acp 0.1.1 bridge forwards
session/new mcpServers to Claude, Claude invokes the forwarded Fusion tool,
and the call traverses the ACP permission gate (session/request_permission).
Both security-critical answers resolve positively — overturns the headless
NOT-GO chain (FN-6466/6467/6473/6476), whose only blocker was running
detached from the login keychain session.
- R17 (daemon auth) recorded and closed for the supported setup: creds are
macOS Keychain-only; the user's login-session fn daemon has keychain access
(the existing claude -p provider authenticates there), so the bridge does too.
- U10: thread an optional mcpServers list through the ACP runtime contract.
newAcpSession now forwards it (was hardcoded []); AgentRuntimeOptions (engine
+ plugin-local copy) gains the field; defaults to [] to preserve Route B's
read-only ask posture. Tool calls still route through the U5 permission floor.
Plugin typechecks clean; provider-session tests 12/12 (incl. 2 new forwarding
tests). U11-U13 (provider transport swap, picker/auth, workflow verify) remain.
