+# July 2026 dependency migration
+
+This receipt records the deliberate consolidated upgrade of the public site and
+Python repository gates. It is a maintenance result, not scientific Evidence.
+
+## Adopted runtime and packages
+
+- Node 24 LTS locally and in GitHub CI; `site/package.json` constrains the site
+  build to Node 24.
+- Astro 7.1.3, `@astrojs/mdx` 7.0.3, and `@astrojs/sitemap` 3.7.3.
+- Tailwind CSS 4.3.3 and `@tailwindcss/vite` 4.3.3. The deprecated
+  `@astrojs/tailwind` integration was removed.
+- Ruff 0.16.0 and mypy 2.3.0.
+- Range-compatible transitive security updates to sharp 0.35.3 and svgo 4.0.2.
+  The consolidated lock also contains devalue 5.8.2 and postcss 8.5.23.
+
+## Breaking-change assessment
+
+Astro 7 moves the site to Vite 8 and removes or changes deprecated interfaces.
+This static site does not use the removed database, transition-internals,
+container-renderer, or reserved `src/fetch.ts` paths. Its production build is
+therefore covered by the normal static-output route inventory.
+
+Astro documents the Tailwind Vite plugin as the preferred Tailwind 4 path and
+the old Astro integration as deprecated. Tailwind 4 replaces the `@tailwind`
+directives with a CSS import and raises its browser floor to Safari 16.4,
+Chrome 111, and Firefox 128. The site uses no Tailwind utility classes whose
+names or semantics changed. Retaining Tailwind Preflight was necessary to
+preserve the existing reset and presentation.
+
+Ruff 0.16 expands its default rules substantially and changes Markdown
+formatting behavior. Synaplex selects only `E9`, `F63`, `F7`, and `F82`, excludes
+the governed eval corpus, and does not invoke `ruff format`; the expanded
+defaults and Markdown formatter therefore do not silently broaden the gate.
+The upgraded binary passed the complete repository lint target.
+
+Mypy 2.x drops Python 3.9 as a host runtime and changes several defaults,
+including local partial types and strict bytes. Synaplex already requires and
+checks Python 3.12, and mypy 2.3.0 passed the maintained publication and
+configuration boundary without suppressions or compatibility edits. The
+upcoming native-parser default remains outside this migration.
+
+Primary upgrade references:
+
+- <https://docs.astro.build/en/guides/upgrade-to/v7/>
+- <https://docs.astro.build/en/guides/styling/#tailwind>
+- <https://tailwindcss.com/docs/upgrade-guide>
+- <https://github.com/astral-sh/ruff/releases/tag/0.16.0>
+- <https://mypy.readthedocs.io/en/stable/changelog.html#mypy-2-3>
+
+## Deterministic and visual verification
+
+`make check` passed under Node 24.18.0, including Ruff, mypy, 54 unittests,
+strict JSON Schema validation, the mechanically blocked experiment check,
+19/19 external canon conformance fixtures, two accepted prompt baseline
+contracts, projection generation, deploy-contract validation, and a 24-page
+Astro build. `npm audit --audit-level=high` reported zero vulnerabilities.
+
+Chromium 1440x1000 full-page comparisons used the same browser executable and
+viewport before and after the migration:
+
+| Route | Pre/post dimensions | Mean absolute RGB delta | Changed-channel ratio |
+| --- | --- | ---: | ---: |
+| `/` | 1440x2950 / 1440x2950 | 0.0220 | 0.000245 |
+| `/lineage/ai-native/` | 1440x2032 / 1440x2032 | 0.0113 | 0.000198 |
+
+Both retained `rgb(242, 240, 233)` as the root background and the same body font
+stack; the lineage headline remained 100.8px. The new
+`/lineage/cadence/` route was separately rendered and inspected, including its
+“Not a Claim. Not Evidence. Not a finding. Not a current study.” boundary.
