Generate a review handoff / PR description for a migration PR in Rob's preferred format — H3 headers + bullets (no tables), wrapped in a 4-backtick fence for clean paste, with a schema/DDL section. Use when asked for a "handoff", "PR description", "review doc", or "something another AI can review".

Recut/port a single domain from the pg-e2e-harness (mono) branch onto develop as a clean, reviewable Drizzle PR during the Neo4j→Postgres migration. Use whenever starting or continuing a domain port — e.g. "recut Language", "port Engagement to PG", "start the Partnership PR", "cut the next spine link". Covers scoping from mono, the schema/repo/handler PR split, the validation gauntlet, decision-surfacing, the PR handoff, and the accumulated gotchas.
