Semantic Blueprints

The bridge between offer-accepted and start-date: ATS owns the pre-employee lifecycle stage (paperwork in flight, pre-boarding tasks open, background check pending). Realizes the `hired` state on `job_applications`. Publishes the `pre_employee.activated` event that hands the canonical reconciliation to HCM-mastered `employees`. Formerly NEW-HIRE-HANDOFF, renamed per §7.1 because HCM canonically masters `employees`.

Requisitions → postings → applications with pipeline-stage lifecycle. Realizes REQ-MGMT and CANDIDATE-EXP (application flow slice). Embedded-masters `candidates`, optionally `hcm_positions` and `org_units` for canonical position/org context.

Employee-driven candidate sourcing with referral-bonus tracking (`candidate_referrals`). Embedded-masters `candidates`. Cross-domain handoffs to PAYROLL (bonus payout) and EMP-EXP (engagement signal).

Curated candidate groupings for nurture and pipeline-building (`talent_pools`). Embedded-masters `candidates`; deployed alone, materializes a thin candidate shell. Mirrors standalone talent-acquisition CRM products.
