fork-contribution-sync overview

Composable fork contribution maintenance component providing infrastructure for keeping a fork in sync with its upstream, detecting breaking changes, and generating migration checklists. Designed for projects that maintain long-lived forks or contribute patches upstream. The module exposes three surfaces: - `createForkSync(config)` — factory that builds task definitions for upstream sync, compatibility testing, API surface snapshotting, and migration diffing. - `executeForkSync(ctx, config)` — convenience wrapper that runs the full sync pipeline and returns a structured result with per-step outcomes. - Preset factories for common patterns: - `createUpstreamSyncCheck(config)` — rebase dry-run against upstream - `createCompatibilityTestSuite(config)` — interface conformance + build integrity - `createApiSurfaceSnapshot(config)` — baseline export snapshot + diff detection - `createMigrationHelper(config)` — AST-based breaking change checklist generation
