Recommendation

Decision note

Rebuilt from the original export under the complete V412/V411 factual-source-verification workflow. Preview only. Apply remains blocked until Failures = 0, Warnings = 0, Unmapped = 0, Missing = 0; explicit clears are reviewed; image import is disabled or V380 accepts the asset; a representative WordPress edit screen is compared with the export and proposed row; and a post-Apply zero-change Preview succeeds.

Strengths

Pros

  • Apache-2.0 open-source framework
  • Vendor-agnostic model integrations
  • Strong control over retrieval and context
Considerations

Cons

  • Advanced pipelines require engineering effort

Considerations

Limitations

Framework flexibility does not remove the need for evaluation, observability, security, and infrastructure operations.

Integration compatibility should be tested against pinned component versions.
