Prepare Methodology 8.0.0 under the existing closed-enum MAJOR policy: reconcile relation-spec wording, provide the pin-only 7.0 → 8.0 recipe with manual compatibility review, align current pins/PRESETS_VERSION, and preserve historical fixtures and diagnostic evidence. Both skill bundle manifests are 0.2.0; requirements-analysis floor is 8.0.0 because its required caller boundary changes.

Exact isolated caller qualification is recorded in transitrix/skills/requirements-analysis/qualification.json and caller-candidate.json: CLI 2.13.0 / diagrams 1.17.0, source f1d5f1e68df5f3df54ffc4a528e77b327dc60859, tarball SHA256 91470eb32fd83a5a6a0a601e890a17944066cab9cf69604299a499f021fcc5ff and npm integrity. Four subjects and retained controls passed (11 actual CLI invocations plus missing-tool refusal and verification-state interpretation), replay matched, all 54 installed files match the archive, and synthetic models stayed unchanged. Runtime-only npm audit reported zero vulnerabilities for this isolated installed set. The skill requires exact integrity/source/receipt match, with no unpinned download or implicit installation.

Hosted packaged UI/CLI parity passed 45 tests in Studio run 42419064679, against VSIX SHA256 9fa60bc4ab604dd11ea1d47e01e9440486205f83a4a9825179ad512c65dcb567. Its CLI was built at synthetic merge df85b60a0383c8bc2c7870c1ae954ec9adb29cae and archive SHA256 600eb7e16b5fe57e5b1c38fbe5a88b44b86102667e7c1ffeea55ef51325ba2c8. Both tracked source trees equal ba35bc45d33e61279dad576e8585f8cf419e77c9. This supports bounded source correlation, not hosted use or byte equivalence of the local archive. Direct exact-artifact parity and final merge/rebuild qualification remain separate.

Validation: doc-lint passed with four baseline catalogue/size warnings; 105 initial migration/shared-instruction tests and the updated shared-instruction suite passed; publication manifests, generated plugin parity and isolated discovery of 12 skills passed. Independent final review returned no actionable findings. The generic Codex skill validator rejects this repository's established min_version/when_to_use extensions; repository convention is preserved. Build-prerequisite and test-apparatus failures remain recorded in preparation evidence and were not labeled product failures.

Companions: Studio #754, reference adopter #101. All remain draft/unmerged. No source release, tag, publication, manual workflow dispatch, effective adopter upgrade or installation into a user product. This receipt does not claim a new assistant-host evaluation, final release qualification or whole-product acceptance.
