Adds docs/methodology.md — the prose deliverable that ties the vk-gramatvediba workspace together for the AI regulatory sandbox. Describes the two-pass transcription pipeline (mechanical transcoder -> curated refinement), the concrete delta between the transcoder skeletons and the curated FG3-4/FG3-5 executables (gateways, DMN extraction, link reconciliation, resource/metadata authoring), the final validation pass (all .bpmn/.dmn well-formed, all 3 L4 packages pass uapf-cli, transcoder samples byte-deterministic), and the implications and limitations for the sandbox. Workspace now closes the 8-step build plan: skeleton, six FG L2 stubs, FG3 L2 + six FG3-x sub-process stubs, FG3-1/FG3-4/FG3-5 executables, register-to-BPMN transcoder, methodology note.
