Barrel Cleanup & Aggregate Export Refactor: @ocom/domain

[nnoce14]

Goal: Remove all barrel files (index.ts that only re-export) and star re-export patterns from @ocom/domain. For each domain context, ensure exports target a single aggregate source file (e.g. <context>.ts) that directly exports entities, value objects, repositories, and unit of work types in a designated //#region Exports region at the bottom. Update package.json "exports" to point to these aggregate files instead of index.ts.

Scope:
packages/ocom/domain -- especially src/domain/contexts/*

Tasks:

• For each domain context folder, audit for index.ts barrel files and constituent code modules
• Create or refactor a context aggregate file (<context>.ts) with clear Exports section
• Migrate all exports to aggregate file (no index.ts barrels)
• Remove index.ts barrel files
• Update imports throughout repo to use aggregate files
• Update package.json exports fields to point at aggregate files
• Add/maintain Biome error-level override (noBarrelFile, noReExportAll) for packages/ocom/domain/**
• Run lint/build/tests locally and using pnpm run verify
• Document path changes (dev docs/README)

Success Criteria:

• All domain contexts aggregate roots have a dedicated entry point, no index.ts barrels remain
• package.json exports use aggregate files, and any other files which need to be exported from @ocom/domain
• Imports across repo reference explicit files, not barrels
• There is no usage of Domain.* namespace pattern import from @ocom/domain anywhere in the codebase.
• Biome config error overrides active for packages/ocom/domain/**
• All builds/lint/tests pass (pnpm run verify)

Risk & Coordination:

• Update may break import paths for downstream packages, coordinate PR merges
• If aggregate files become unwieldy, consider splitting logic but keep exports centralized
• Watch for accidental circular references previously masked by barrels

Checklist:

• Audit contexts
• Refactor/create aggregate files & exports
• Remove index.ts barrels
• Update package.json exports
• Update all imports
• Add Biome override
• Run verify
• Document changes
