Summary

• Master hub Book a client: lookup by phone / @username / id, or create a walk-in (manual_clients)
• Shared slot funnel → book_for_client as confirmed (ignore_min_lead, horizon kept); TG clients get a push, walk-ins do not
• Schema XOR client_user_id / manual_client_id, contact resolver, skip client reminders/pushes for manuals; README + help

Test plan

• A: search by @ / id / phone → book → client push, confirmed in My bookings, no master new-booking push
• B-lite: New client → book; search same phone → no duplicate; master reminder shows name+phone; no client reminders
• Master cancel of manual appointment — no errors / no client push
• Time off / work days warning shows manual client name
• Client self-book + pending confirm still work
• CI green (unit + integration if Postgres available)
