Phase agent that watches the post-merge deployment for a ticket. Reads the merge SHA from phase-monitor-merge.json (the signal file phase-monitor-merge writes after gh pr merge confirms via REST), subscribes via catalyst-events wait-for to deploy events on that SHA, then delegates a live verification check to the /canary skill (gstack). Emits phase.monitor-deploy.complete.<TICKET> on canary success, phase.monitor-deploy.failed.<TICKET> on deploy or canary failure, and phase.monitor-deploy.skipped.<TICKET> when no deploy event arrives before the timeout. Dispatched by the phase-agent orchestrator (CTL-452) via slash command — user-invocable: true so the dispatcher's claude --bg "/catalyst-dev:phase-monitor-deploy ..." resolves.
