Slingshot v1.0.0 — Entity Conformance and Transaction Contracts
Slingshot WP1 and WP2 through Phase 4.
Highlights:
- public entity backend capability profiles and the cross-backend conformance runner
- public transaction scope, manager, lifecycle errors, and semantic step contracts
- scoped entity and Drizzle adapters on one PostgreSQL client
- preflight transaction topology validation, rollback-only handling, and deferred effects
- fresh-database notification delivery fix
Phase 5 is intentionally not included and remains paused at the clean handoff point.
Validation:
- protected-branch Entity Conformance, Docs & Dependency Rules, and Hardening Core checks passed
- all 43 independently packed packages installed and imported successfully
- full Bun and Node test suites passed
