A PM bot is not a chatbot you brainstorm with. It's a process manager — it takes the complete inputs for one SevenD phase and runs that phase to a decision.
Feed the Discovery PM a raw idea and market context, and it comes back with a prioritized backlog. Feed the Design PM an approved spec, and it comes back with a locked component registry and interface contracts. Every bot enforces the same phase gates the SevenD framework already enforces on humans and coding agents — no spec without a backlog item, no code without a completed design, no deploy without diagnostics passing.
