Closes #916. Shared CI prerequisite for #903, #906, #910 and #911 in the production audit.

Both mock and live browser jobs now install the browser from the locked Playwright CLI and launch Chromium on the original runner. The readiness check renders a French-labelled button, captures a screenshot and finalizes a video using the pinned FFmpeg. When that fails, it invokes the standard distribution dependency installer under a four-minute limit, then repeats the check. A failed second check fails setup. The existing npm test commands, both live architectures, dashboard and API URLs, Node 24, Kind credentials and artifact collection continue through their existing workflow steps.

On Ubuntu 24.04 amd64 with Node 24.22.2 and Playwright 1.65.0, the helper succeeded in 10.87 seconds with a cold browser cache and 1.86 seconds with a warm cache. A missing native library selected the fallback, which failed when the test environment denied dependency installation. Bash syntax, ShellCheck, Actionlint, zizmor and Git diff checks passed. On the first hosted amd64 run, Chromium setup completed in 12 seconds and all 83 applicable mock browser tests passed. Hosted mock result.

The underlying failure reproduced on fresh GitHub runners without a source change. Mock retry · Live amd64 retry · Live arm64 failure

The independent design comparison and pseudo-locale jobs also failed to resolve Ubuntu’s font packages. At commit 3829f05e, both use the official Playwright image pinned to its multi-architecture digest, with read-only access to the hosted runner’s system fonts. The workflow verifies the image driver matches the locked npm version. The existing screenshot comparisons, clipping assertions and artifact uploads run in that environment. Actionlint and zizmor passed. The exact setup rendered and recorded Chromium offline with Node 24.22.2 and rejected a mismatched image version. Original design job. The dedicated design job passed all 124 capture tests and all 116 baseline comparisons. The en-XA job passed 124 tests with seven pre-existing skips. Design comparisons · Pseudo-locale and clipping.

All browser checks passed at signed commit 3829f05. The regular mock suite passed 83 cases in 3.8 minutes with 55 mode-specific skips. The live Kind suites passed 61 cases each, with 77 mode-specific skips per architecture. The amd64 suite took 7.4 minutes and arm64 took 6.0 minutes. Both used the original bootstrap admin session, real API port-forward and colocated browser. Mock · Live amd64 · Live arm64 · CI report

Scope after the TypeScript 7 merge

The plain-HTTP TypeScript editor check and its lint toolchain verifier landed in #902. The mock job builds the production dashboard after the new Chromium probe and uses the verified browser to check diagnostics and completion over LAN HTTP. The integration against master now changes the browser setup in two workflows, the Chromium helper and its release note. Workflow diff · Plain HTTP and mock results · Changelog

Browser qualification on the current integration

On 38c1d157, the production dashboard’s TypeScript check over plain HTTP passed in 5.2 seconds. The first diagnostic appeared in 2,310 ms and completion in 147 ms. The mock suite passed 85 cases in 3.9 minutes, with 55 mode-specific skips. Both native Kind suites passed 61 cases each, with 79 mode-specific skips per architecture. The amd64 suite took 7.8 minutes and the arm64 suite took 6.2 minutes. Mock and HTTP editor · Live amd64 · Live arm64

Both design and pseudo-locale jobs passed 124 capture tests with seven skips each. All 116 design baseline comparisons passed. Design comparisons · Pseudo-locale · Issue evidence

Summary by CodeRabbit

  • Chores
    • Updated automated browser checks to use the project’s locked Playwright tooling to install Chromium.
    • Browser checks verify that Chromium can render a page, capture a screenshot, and record a video. If the initial check fails, required browser dependencies are installed and the check is retried.
    • Screenshot checks now use a pinned Playwright environment, verify the browser tooling version, and include system fonts from the runner.

All eligible CI gates passed on the signed head 38c1d157, including the mock and live browser suites. Final CI report

Walkthrough

The browser workflows now use a shared Chromium setup script. It probes browser operation and installs Chromium’s system dependencies before retrying when the initial probe fails. The visual-diff jobs also use pinned Playwright containers and verify the driver version.

Changes

Browser CI setup

Layer / File(s) Summary
Chromium installation and browser probe
web/e2e/install-chromium.sh
The script installs Chromium through the local Playwright CLI, then checks browser launch, rendering, screenshot capture, and nonempty video recording. If the probe fails, it installs Chromium dependencies and retries.
Browser workflow integration
.github/workflows/ci.yaml, .github/workflows/visual-diff.yaml
The mock and live jobs invoke the installer, with the live job running npm ci from its web working directory first. Visual-diff jobs use pinned Playwright containers, mount runner fonts read-only, verify driver and package versions, and run the installer.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Full details: Title check

Explanation

The title "fix(ci): probe Chromium before installing browser dependencies" matches the main change. The changeset adds web/e2e/install-chromium.sh, which installs Chromium through the locked Playwright CLI, probes it (render, button screenshot, nonempty video), and only installs distro dependencies with a four-minute limit when the first probe fails. The workflows in ci.yaml and visual-diff.yaml now call this script instead of the previous npx playwright install step. The title is short, specific, and follows the conventional-commit style.

Full details: Out of Scope Changes check

Explanation

The browser-install changes in .github/workflows/ci.yaml, web/e2e/install-chromium.sh and .github/workflows/visual-diff.yaml relate to #916. The visual-diff change addresses the same Ubuntu package failure for the design and pseudo-locale jobs. This is a plausible extension, and the PR description explains it. The incremental diff from previous head a65928b to head 6aa1d34 adds changes that do not relate to browser setup. In .github/workflows/ci.yaml, the web-i18n job adds a scripts/check-lint-toolchain.sh verification step. It also renames the eslint step to ESLint and Oxlint. The PR description does not mention these changes. Neither change implements #916 or the browser-install objective. The commit subject refers to preserving the TypeScript editor check. The added HTTP TypeScript step in the mock job can be tied to that subject. The lint toolchain and lint step rename cannot.

Resolution

Remove the lint toolchain verification step, its referenced script, and the lint step rename from this PR. Or move them to a separate PR with its own linked issue and description. Update the PR description to explain any retained HTTP TypeScript editor step and its connection to browser setup.

Full details: Linked Issues check

Explanation

[#916] Implementation matches the acceptance criteria at the reviewed head. web/e2e/install-chromium.sh installs Chromium through the locked Playwright CLI. It probes launch, render, screenshot and video. On probe failure it runs npx playwright install-deps chromium under a four-minute limit, then probes again. A failed second probe exits non-zero. The mock and live browser jobs in .github/workflows/ci.yaml call this helper. Live amd64 and arm64 steps and the mock suite remain in the workflow. The previous FAIL was caused by pending runs. The PR description now links mock and live runs, but those runs state commit 3829f05. The reviewed head is 6aa1d34. The head adds commits that the cited runs did not exercise: a dashboard lint toolchain step, a production build step, and a playwright test --config=e2e/http/playwright.config.ts step in the mock job. The qualification required by #916 is therefore not established for the reviewed head. The hosted run results could not be verified from the repository.

Resolution

Run the mock suite and both live Kind architectures (amd64 and arm64) at head 6aa1d34. Record the run links in the PR description for #916. Confirm that the new mock-job HTTP TypeScript step passes at that head.

2270-2270: Functional Correctness

The arm64 job uses the shared setup. The pending hosted results do not establish that the required runs were skipped or failed.

web/e2e/install-chromium.sh: 1

17-17: Functional Correctness

The probe does not check font selection, but the inspected CI path does not run the screenshot gallery. The evidence does not establish that a missing font causes a failure in the affected suites or that the dependency installer supplies a required font.

@ValgulNecron, the release note documents which CI jobs now launch Chromium, when Ubuntu dependency installation runs, and how CI verifies the repair. Changelog entry

I checked the scope against the current master for the CodeRabbit review. The TypeScript lint toolchain verifier and the plain-HTTP editor check landed in #902. This PR changes the Chromium installation step that precedes the editor check. On the prior integration 6aa1d349, that check exercised the production dashboard over plain HTTP and reported the first diagnostic in 3,080 ms and a completion suggestion in 148 ms. The regular mock suite then passed 85 tests with 55 mode-specific skips. Scope review · Workflow diff against master · Plain HTTP and mock results

On the same integration the design capture and en-XA suites each passed 124 tests with seven skips. All 116 design comparisons passed, and the arm64 live Kind suite passed 61 cases with 79 mode-specific skips. The signed integration 38c1d157 includes the latest merged upstream changes. Its browser helper and the two workflows are byte-identical to 6aa1d349. Design · Pseudo-locale · Live arm64 · Current CI

All requested qualification runs passed on signed commit 38c1d157. The mock suite passed 85 tests and each live Kind architecture passed 61. Both screenshot suites passed 124 captures, and all 116 baseline comparisons passed. Exact-head evidence for #916 · Final CI report
