+# Task 14 report: integrated TechLog parity and release verification
+
+## Status
+
+`DONE_WITH_CONCERNS`. The migrated UI, committed browser evidence, source-to-target
+comparison, sample-removal gate, focused suites, static gates, and production
+build pass. The only concern is the repository's pre-existing restricted-runner
+`test:all` baseline: child-process-heavy tests cannot spawn in the managed
+sandbox, and 19 provider-environment cases remain red even when isolated with
+the required process scope. The isolation and exact counts below prove that no
+TechLog test is among those failures.
+
+The work remains on `feature/techlog-ui-migration`. It was not merged, pushed,
+finished with GitFlow, or deleted. Task 14 is committed by this report's commit,
+`test: prove TechLog UI migration parity`.
+
+## Evidence files
+
+Added or replaced product evidence:
+
+- `tests/visual/tech-log.visual.spec.ts` and 111 target-only PNG snapshots. The
+  suite has 112 cases because canonical and state coverage for the 1440-pixel
+  `/studio/publications` screen deliberately share the same reviewed image.
+- `tests/e2e/tech-log-public-discovery.spec.ts`,
+  `tests/e2e/tech-log-accessibility.spec.ts`, and
+  `tests/e2e/tech-log-responsive.spec.ts`.
+- `tests/support/browser/tech-log-fixtures.ts` and the external, manually run
+  `tests/support/browser/verify-tech-log-source-parity.ts` evidence harness.
+- Focused regressions in `tests/unit/vite-route-chunks.test.ts`,
+  `tests/unit/design-system-source.test.ts`, the bounded-body reader tests, the
+  router component suite, and TechLog feature suites.
+- Governed registry, dependency, release, CI, and operations evidence in
+  `config/contracts`, `config/security`, `config/ci`, the generated Gitea
+  workflow, `README.md`, and
+  `docs/operations/techlog-ui-migration-baseline.md`.
+
+Removed starter-only evidence:
+
+- `tests/e2e/compact-smoke.spec.ts`,
+  `tests/e2e/design-system-interactions.spec.ts`, `tests/e2e/i18n.spec.ts`, and
+  `tests/e2e/theme.spec.ts`.
+- `tests/visual/platform.visual.spec.ts` and all five platform visual PNGs.
+
+The retained `app-shell`, registry-wide accessibility, and responsive suites
+were rewritten around TechLog. No stale starter browser or visual snapshot is
+left referenced.
+
+## Source-to-target visual method and result
+
+The supplied source at `/home/donghyeon/workspace/techlog-studio-frontend` was
+never written. It was copied to `/tmp/techlog-source-parity.I0CBK7`; build and
+Vinext runtime caches were created only in that temporary copy. The source
+production server and target Vite preview were opened by one Playwright Chromium
+instance with two fresh contexts and the following identical controls:
+
+- device scale factor 1, light color scheme, `ko-KR`, `Asia/Seoul`, reduced
+  motion, service workers blocked, 1000-pixel viewport height, and full-page
+  screenshots;
+- fixed clock `2026-08-14T01:00:00.000Z`, deterministic in-memory data,
+  `document.fonts.ready`, matching Pretendard/IBM Plex Mono font-face state,
+  and zero-duration animation, transition, and caret styles;
+- no masks and no tolerance: exact RGBA pixel comparison, product-subtree
+  tag/class/text/ARIA projection, layout diagnostics, and console/page/request
+  failure collection.
+
+The final external comparison command was:
+
+```bash
+TECH_LOG_SOURCE_URL=http://127.0.0.1:4275 TECH_LOG_TARGET_URL=http://127.0.0.1:4274 corepack pnpm exec tsx tests/support/browser/verify-tech-log-source-parity.ts
+```
+
+Result: **112/112 passed**, 0 failed, `totalDifferentPixels=0`, every DOM/class/
+text/ARIA projection equal, and 0 unexplained source/target errors. Source
+screenshots were temporary comparison inputs; none was copied into target
+snapshots. The no-update target visual run also passed 112/112 with
+`maxDiffPixels=0` and `maxDiffPixelRatio=0`.
+
+The comparison found and corrected actual integration defects rather than
+accepting drift: the TechLog Tailwind bootstrap is loaded exactly once in the
+same cascade order as source; the starter theme import is removed; CSS-module
+class mapping, shell navigation/focus, publication labels and states, router
+404 handling, and generated Vite route-chunk lookup now follow source. All five
+source/target CSS pairs pass `cmp -s`; their hashes are recorded in the
+operations baseline.
+
+Source production returns missing dynamic slugs and an unmatched Public path as
+HTTP 404, `text/plain`, with the exact nine-byte body `Not Found`. Curl and
+Chromium regression evidence therefore fixes the target to that shell-free
+response. This is an observed source-production contract and satisfies the
+planned prohibition on a generic runtime error; it is not a redesign.
+
+## Route, viewport, and state inventory
+
+The 27 canonical contract routes were each compared at 360 and 1440 pixels:
+
+- Public: `/`, `/explore`, `/explore/:kind`, `/cases/:slug`,
+  `/references/:slug`, `/questions/:slug`, `/topics/:slug`, `/projects`,
+  `/projects/:slug`, the `records`, `decisions`, and `activity` project views,
+  `/releases`, `/releases/:version`, `/profile`, `/search`, and `*`.
+- Studio: `/studio`, `/studio/documents`, `/studio/documents/new`, the `edit`,
+  `validation`, `preview`, and `publish` document views,
+  `/studio/publications`, publication-event preview, and `/studio/*`.
+
+All known Public fixtures were exercised: two cases, two references, two open
+questions, three topics, both projects and all three nested views, and release
+`0.1.0`. Ten unknown Public dynamic shapes were also compared at both widths.
+
+The 112-case matrix is 54 canonical-route captures, 12 home breakpoints (1180,
+1179, 1050, 1024, 980, 900, 820, 768, 767, 420, 390, and 375), 19 Studio
+states, 20 unknown-Public captures, and 7 interactions. Studio states cover the
+dashboard, list/new, Case/Reference/Question/conflict editors, valid/invalid
+validation, current/missing/expired previews, ready/blocked publish,
+publications/snapshot, missing document/publication, and unknown Studio route.
+Interactions cover Public search, Studio mobile menu, immediate preview,
+dirty-leave dialog, newly created current preview, unpublish confirmation, and
+warning acknowledgement through publish-ready state.
+
+## Browser, responsive, and accessibility outcomes
+
+- Required four-spec Chromium command: **48/48 passed**. It covers Public
+  discovery, the full Studio workflow, responsive behavior, and accessibility.
+- Responsive plus accessibility focused command: **26/26 passed**.
+- Exact target visual command: **112/112 passed** in 2.5 minutes with no masks
+  and zero pixel tolerance.
+- Keyboard/focus checks cover Public search dismissal/restoration, Studio mobile
+  navigation, dirty-leave and unpublish dialogs, labels, heading/landmark order,
+  and focus-visible behavior. Axe reports no violations in the required route
+  and state inventory. Overflow assertions pass at the compact and transition
+  widths, and no unexpected console, page, or request error remains.
+
+Commands:
+
+```bash
+corepack pnpm exec playwright test tests/e2e/tech-log-public-discovery.spec.ts tests/e2e/tech-log-studio-workflow.spec.ts tests/e2e/tech-log-responsive.spec.ts tests/e2e/tech-log-accessibility.spec.ts --project=chromium

+corepack pnpm test:visual
+```
+
+## Registry and supply-chain governance
+
+The initial no-baseline registry artifact reported 23 migration-owned breaking
+IDs. Each now has owner `tech-log-frontend`, a TechLog contract-version reason,
+atomic route/runtime/manifest installation, same-release compatibility, and
+rollback to `05e3d50ba01f01c27f257d2e9040c2bc413ea053`:
+
+- Contract: `$contract:{allowedValues,breakingFields,fieldTypes,requiredFields}`.
+- Removed route rows: `APP_HOME`, `EXAMPLES_AUTH`, `EXAMPLES_PLATFORM`,
+  `EXAMPLES_STATES`, `EXAMPLES_UI`, `REFERENCE_RESOURCE_DETAIL`,
+  `REFERENCE_RESOURCE_FORM`, `REFERENCE_RESOURCE_LIST`, and
+  `REFERENCE_RESOURCE_STATUS`.
+- Runtime removals: the same nine route IDs.
+- Runtime change: `NOT_FOUND:moduleId:field-changed`.
+
+The governed update used exactly:
+
+```bash
+REGISTRY_BASELINE_OWNER=tech-log-frontend REGISTRY_BASELINE_REASON="Install approved TechLog Public and Studio route contract" node scripts/update-registry-baseline.ts artifacts/quality/registries.json
+corepack pnpm check:registries
+```
+
+Final result: 11 registries pass, compatibility `none`, no unacknowledged
+change. Approved snapshot digest:
+`428479ac5845374a82dd7d02a0c59a713106405f031cdc153789174f14c1405b`.
+
+Six direct dependency additions have evidence owner `tech-log-frontend`,
+reviewer `frontend-platform-security`, product-specific reason, and atomic
+rollback: `@fontsource/ibm-plex-mono@5.3.0`, `pretendard@1.3.9`,
+`remark-directive@4.0.0`, `remark-gfm@4.0.1`, `remark-parse@11.0.0`, and
+`unified@11.0.5`. The dependency policy recognizes the font packages' OFL-1.1
+license. Supply-chain generation covered 641 packages. The pre-existing
+dependency baseline was not promoted; the denied promotion was unnecessary for
+the regular verification path, which passes with the committed evidence.
+
+## Sample removal and fresh verification
+
+The final staged-candidate command passed:
+
+```bash
+corepack pnpm test:sample-removal
+```
+
+Result: **PASS (13 checks, no fixture IDs)**. Its internal evidence included
+types; reduced architecture (383 modules/1,173 dependencies, 12 graph checks,
+9 forbidden fixtures); 11 registry checks; runtime schema 3 files/40 tests;
+unit 115/1,247; component 18/124; integration 8/74; recipes 2/17; coverage 164
+files/1,653 tests at 77.41% statements, 73.26% branches, 83.89% functions, and
+80.03% lines; risk coverage 382/382 with 76 thresholds; source evidence 198
+files/111 baselines; artifact/CI checks; router smoke 9/9; and production build.
+
+Fresh completion commands and results:
+
+| Command | Result |
+| --- | --- |
+| `corepack pnpm exec vitest run tests/features/tech-log` | 21 files, 170 tests passed |
+| required four-spec Chromium command above | 48 tests passed |

+| `corepack pnpm check:browser-security` | injection rejected; Public source maps absent |
+| `corepack pnpm build` | 2,352 modules transformed; build and manifest completed |
+| `git diff --check` | passed |
+
+The exact managed-workspace `corepack pnpm test:all` passed runtime schema 3/40,
+then its unit phase passed 117 files/1,738 tests and failed 50 tests in only
+three child-process-heavy files due to `spawnSync ... EPERM`: 39
+`ci-artifact-contract`, 2 `ci-workflow-generation`, and 9
+`http-scenario-evidence`. No TechLog test failed. The exact isolated command:
+
+```bash
+corepack pnpm exec vitest run tests/unit/ci-artifact-contract.test.ts tests/unit/ci-workflow-generation.test.ts tests/unit/http-scenario-evidence.test.ts
+```
+
+ran 3 files/529 tests: 510 passed; all 407 CI-workflow and all 14 HTTP-scenario
+tests passed; the remaining 19 pre-existing CI-artifact provider/cgroup,
+RLIMIT/EMFILE, umask, `/tmp`, timing, and identity cases failed. Direct runs of
+the aggregate's remaining phases passed: component 18/124, integration 11/82
+under the required child-process scope, reference feature 4/13, and recipes
+2/17. This environment-only baseline is also recorded in the operations
+baseline.
+
+## Fixes, branch audit, and handoff
+
+Root-cause-driven fixes added regressions for generated Vite manifest chunk
+resolution, source-compatible raw 404 responses, palette-source detection, and
+abort rejection. Presentation integration corrections preserve source DOM,
+ARIA, copy, assets, CSS, workflow state, and focus behavior; no design was
+introduced. The branch-wide audit of
+`05e3d50ba01f01c27f257d2e9040c2bc413ea053..HEAD` found no migrated
+presentation import of adapters, Next.js, Vinext, or Cloudflare. The 27 route
+chunks are present in the release manifest and derive from actual Vite output,
+not hard-coded generated filenames.
+
+Before the Task 14 commit, the full migration range contains the 21 prior
+commits from baseline establishment through `c5c8b94` and changes 352 files
+(26,025 insertions, 3,467 deletions). This report's commit adds the integrated
+parity evidence and fixes with the exact message
+`test: prove TechLog UI migration parity`. Final status and range are checked
+again after the commit; integration remains explicitly deferred.

+
+All five source/target pairs passed `cmp -s` and have identical SHA-256
+digests. Production parity testing corrected the provisional bootstrap
+assumption in the design: the target loads the byte-identical TechLog
+`globals.css`, including its first-byte `@import "tailwindcss";`, exactly once
+and does not load the starter `theme.css`. This reproduces the source cascade;
+the resulting browser comparison is pixel-identical.
+
+## Source-to-target browser parity
+
+The source was copied to `/tmp/techlog-source-parity.I0CBK7` before build and
+runtime caches were created. The supplied source directory was used only for
+read-only file comparison; it was not edited. The temp-copy Vinext production
+server and the target Vite preview were captured by one Playwright Chromium
+instance with two fresh contexts under identical conditions:
+
+- `ko-KR`, `Asia/Seoul`, light color scheme, reduced motion, device scale 1,
+  service workers blocked, and a fixed `2026-08-14T01:00:00.000Z` clock;
+- 1000-pixel viewport height, full-page screenshots, `document.fonts.ready`,
+  Pretendard/IBM Plex font checks, zero-duration animation/transition/caret;
+- no screenshot masks; exact RGBA pixel comparison plus product-subtree
+  tag/class/text/ARIA projection and console/request failure comparison.
+
+| Evidence group | Cases |
+| --- | ---: |
+| 27 canonical routes at 360 and 1440 pixels | 54 |
+| Public home breakpoint transitions | 12 |
+| Studio screen/state fixtures | 19 |
+| Ten unknown Public dynamic shapes at 360 and 1440 pixels | 20 |
+| Search/menu/preview/dialog/publication interactions | 7 |
+| **Total** | **112** |
+
+Result: 112/112 passed, zero failed, zero different pixels, all DOM/class/text/
+ARIA projections equal, and zero unexplained source or target console/request
+errors. The target-only visual regression suite exercises the same 112 cases
+against 111 committed PNGs; the canonical and Studio-state 1440-pixel
+`/studio/publications` cases intentionally share one identical snapshot.
+Source screenshots were temporary comparison inputs and were not copied into
+the target snapshot directory.
+
+The production source responds to both a missing dynamic slug such as
+`/projects/missing-project` and an unmatched path such as
+`/definitely-not-a-product-route` with HTTP 404, `text/plain`, and the exact
+nine-byte body `Not Found`. The target intentionally removes the Public shell
+for those paths and matches that response in curl and Chromium regressions;
+this is the observed production source contract, not a generic runtime error.
+
+## Governed route migration
+
+The migration records 23 TechLog-owned breaking-change evidence IDs with owner
+`tech-log-frontend`, an atomic same-release route/runtime/manifest migration,
+and rollback to `05e3d50ba01f01c27f257d2e9040c2bc413ea053`. The accepted registry
+snapshot digest is
+`428479ac5845374a82dd7d02a0c59a713106405f031cdc153789174f14c1405b`;
+its approval reason is `Install approved TechLog Public and Studio route
+contract`. Final compatibility impact is `none` with no unacknowledged change.
+
+## Restricted-environment test baseline
+
+The exact repository aggregate command was run in the managed workspace:
+
+```bash
+corepack pnpm test:all
+```
+
+Its runtime-schema phase passed 3 files/40 tests. The unit phase passed 117
+files/1,738 tests and reported 50 failures in three child-process-heavy files:
+39 `ci-artifact-contract`, 2 `ci-workflow-generation`, and 9
+`http-scenario-evidence`. Every failure was rooted in `spawnSync ... EPERM` in
+the restricted process sandbox; no `tests/features/tech-log` test failed.
+
+The failing files were then reproduced in isolation outside that child-process
+restriction:
+
+```bash
+corepack pnpm exec vitest run tests/unit/ci-artifact-contract.test.ts tests/unit/ci-workflow-generation.test.ts tests/unit/http-scenario-evidence.test.ts
+```
+
+Result: 3 files/529 tests, 510 passed and the pre-existing 19 environment-only
+`ci-artifact-contract` cases failed. The 407 `ci-workflow-generation` and 14
+`http-scenario-evidence` tests all passed. The remaining exact 19 are the
+documented provider lifecycle/cgroup, RLIMIT/EMFILE, restrictive-umask, and
+`/tmp` timing/identity cases; they contain no TechLog code or test. The
+aggregate phases after unit were also run directly: component 18 files/124
+tests, integration 11 files/82 tests under the required child-process scope,
+reference feature 4 files/13 tests, and recipes 2 files/17 tests all passed.

 The inventories in this document are human review baselines. Automated
