What & why

This PR makes a release run the 19 end-to-end tests in e2e-tests/ on an emulator and wait for them, and it removes the Trailblaze suite that gated a release until now. That includes everything #1057 added for it. After this PR, the verify-e2e job is the only device gate on a publish, and that job has never run inside a real release. The tests and their CLI come from #1046, where the verify-clerk-android skill is the instructions that point an agent at them. Until now they ran only on the machine of whoever was working on a change. They cover every scenario the trails did, including the three #1057 added: sign-up with a phone code, finishing MFA setup with an authenticator code, and deleting the account from Security.

• .github/workflows/verify-e2e.yml (Verify end-to-end tests) runs every test on an emulator on the runner itself, with e2e-tests/bin/control-clerk-android up, run --all --backend local --retries 1 --github-report, and down.
• manual-release.yml calls it as the verify-e2e job. create-release needs verify and verify-e2e, and publish runs only when both succeeded. Nothing runs it for a pull request.
• The Trailblaze suite is deleted: trails/, scripts/run-trailblaze-tests.sh, scripts/run-e2e-shard.sh, scripts/e2e/, trailblaze-e2e.yml, and its job in the release workflow with the CLERK_TEST_KEYS_JSON secret it passed.
• The test app loses what only the trails used: the second home in TrailApp.kt, E2EViewModel.kt, the status panel, the account cleanup and its exported broadcast receiver, the TOTP typer, the fixtures, their unit tests, the flat tags in E2ETags.kt, and the E2E_CLERK_KEY_NAME lookup in .keys.json. Every launch now shows the same home.
• e2e-checks.yml is deleted. Its contract check read the trails, and its other step ran :e2e:testDebugUnitTest, which android-test.yml has run on every pull request that is not a draft since feat(verify): add the end-to-end test package and the verify-clerk-android skill #1046.
• A test that fails an assertion or times out runs once more. A failure of the device driver is not retried. A test that fails and then passes is reported as flaky in the job summary, and the job stays green. A test that fails twice fails the job, and the release stops.
• The run creates its own Clerk application and deletes it in down. That needs the repository secret MOBILE_VERIFICATION_PLATFORM_API_KEY. Without it the job fails in its first step and says why.
• The evidence is uploaded as the artifact verify-e2e-android and kept for three days, unless the CLI's search finds a secret value in the run's files.
• This PR sits on feat(verify): add the end-to-end test package and the verify-clerk-android skill #1046, which sits on test(e2e): configure the e2e host from verify launch extras #1041. feat(verify): borrow an emulator on a CI runner when the machine cannot run one #1069 sits on this PR.

To try it, start the workflow by hand on a branch:

$ gh workflow run verify-e2e.yml --repo clerk/clerk-android --ref <branch>

What to focus on

Three commits, in dependency order.

Commit	Lines	What it does
1. The workflow	144 added, 4 removed	Adds a workflow that runs every test on an emulator on the runner, and makes a release wait for it.
2. Docs	4 added, 3 removed	Tells an agent to prove its own change with the test for it, and to leave the full run to the release.
3. The Trailblaze removal	7 added, 3,134 removed	Deletes the Trailblaze trails, their workflows and scripts, and the screens and helpers in the test app that only they used, including what #1057 added.

• The release path has not run. It cannot run without publishing, so the needs: and if: changes in manual-release.yml are read and linted only.
• The tests run before the release is created. A failure leaves no tag, no GitHub release, and no Maven artifacts, so the release can be started again once the cause is fixed.
• A release that someone creates by hand in GitHub reaches publish through the release event. There create-release is skipped, so the tests gate publish only, and the release already exists when they run.
• Every release waits for the tests, and no input turns them off. The job stops after 40 minutes and the test step after 20.
• The retry hides a test that fails once from the release.
• One profile test, "the home UserButton opens the profile of the signed-in user", failed twice in one earlier run of this workflow, and the cause is not known. The workflow uploads app.log and a filtered copy of the device driver's log so that a repeat can be diagnosed.
• The key is a repository secret, like the Maven and signing secrets, so anyone with write access can read it from a workflow on a branch they push. It belongs to a Clerk workspace kept for throwaway test applications.
• A run started by hand on main does not cancel the tests of a release in progress, because the concurrency group includes the caller's workflow name.
• A cancelled job can end before down. A later run of the CLI deletes the leftover application after two hours.

Verification, for this PR and for #1041 and #1046:

The verify-e2e workflow, started by hand on head 0b1c6b3ba, passed twice in a row, in run 38303331260 and run 38304677528. Each run passed 19 of 19 tests on an emulator, with no test retried. The head has since changed only in documentation.

At this head the unit tests in e2e-tests/ pass 521 of 521 and tsc reports nothing. :e2e has 7 unit tests, and git grep -i trailblaze finds nothing.

📝 Walkthrough

This pull request removes the Trailblaze-based Android E2E infrastructure and host-app flows. It adds a reusable and manually triggered workflow that runs golden specs on an Android emulator, validates and uploads run evidence, and gates release creation and publishing.

Changes: Android E2E Verification Migration

Layer / File(s)	Summary
Remove Trailblaze tests and automation .github/workflows/e2e-checks.yml, .github/workflows/trailblaze-e2e.yml, scripts/e2e/*, scripts/run-*.sh, trails/*	The Trailblaze workflows, runners, validation scripts, scenario files, configuration, and documentation are removed.
Make the E2E host verification-only e2e/build.gradle.kts, e2e/src/main/..., e2e/src/test/...	MainActivity now always displays VerifyApp. Launch configuration no longer records whether verification inputs are present. The build uses E2E_CLERK_PUBLISHABLE_KEY when set, or the placeholder key otherwise. The custom OTP, account cleanup, and TOTP flows and related tests are removed.
Run golden specs and validate evidence .github/workflows/verify-e2e.yml	The new workflow provisions an Android emulator, builds the local host, and runs golden specs with one retry. It checks run metadata and uploads evidence only when the checks pass.
Gate releases and document verification .github/workflows/manual-release.yml, .claude/skills/verify-clerk-android/SKILL.md	Release creation and publishing now require E2E verification. The maintainer guidance describes spec selection, workflow triggers, evidence, the required secret, and runner configuration.

🌐 Web query:

GitHub Actions documentation workflow_dispatch select branch run workflow checkout github.ref default event ref

💡 Result:

When you manually start a `workflow_dispatch` run, the **Branch** dropdown selects the branch to run on. That selected branch becomes the event ref: GitHub documents `GITHUB_REF` as the branch or tag that received the dispatch, and `GITHUB_SHA` as its latest commit. ([docs.github.com](https://docs.github.com/en/actions/how-tos/manage-workflow-runs/manually-run-a-workflow?utm_source=openai))

So the default checkout uses the selected ref:

```yaml
steps:
  - uses: actions/checkout@v6
```

To check out a different ref explicitly, pass it to `actions/checkout`:

```yaml
  - uses: actions/checkout@v6
    with:
      ref: ${{ github.ref }}
```

The workflow file must exist on the default branch for `workflow_dispatch` to be available. GitHub’s manual-run documentation also covers selecting a branch in the UI and using `--ref` with the CLI. ([docs.github.com](https://docs.github.com/en/actions/how-tos/manage-workflow-runs/manually-run-a-workflow?utm_source=openai))

Keep branch-selected code away from the Platform API key.

A manual dispatch can select another branch, and actions/checkout@v7 checks out that event ref by default. The up, run, and down steps then run that branch’s control-clerk-android with CLERK_PLATFORM_API_KEY. Unreviewed branch code can read or misuse the key. Put the secret in a protected GitHub environment restricted to trusted refs and requiring approval, or run the key-bearing work only from a trusted revision.

Not changing this in the PR.

Starting a workflow by hand needs write access to the repository, and anyone with write access can already push a branch whose workflow reads any repository secret. A gate on this one dispatch would not change who can reach the key.

Every other secret in this repo works the same way. manual-release.yml can be dispatched on any branch and reads the Maven Central credentials and the signing key as plain repository secrets, and no workflow here uses a protected environment.

Putting this key behind a protected environment means moving the secret in the repository settings, which this PR cannot do. It would also guard a test-only key more tightly than the publish credentials: this key can create and delete applications in one workspace that holds only throwaway test applications. If the repo moves its secrets into protected environments, this job should follow.

Leaving the thread open for a maintainer to decide.

🤖 Generated with Claude Code

[coderabbitai]

@mikepitre Thanks for the guidance. Your write-access explanation changes the risk assessment: this dispatch does not give a new group access to the key. A gate on this workflow alone would not address repository-wide secret access.

I should have framed this as repository-wide hardening, not a required change for this PR. No change is requested here. The finding can stay open for the maintainer’s decision.

Would you like a follow-up issue for repository-wide protected environments?

Learning: In clerk/clerk-android, MOBILE_VERIFICATION_PLATFORM_API_KEY is scoped to one workspace containing only throwaway test applications and permits application creation and deletion. The repository's existing secret-access model trusts users with write access, including branch-selected manual workflows. Treat protected environments as repository-wide hardening rather than a requirement unique to .github/workflows/verify-e2e.yml. If the repository adopts protected environments for secrets, this workflow should follow that policy.

Looks good once the stack below lands. No Trailblaze leftovers that I could find, and the release gate wiring (create-release/publish needing verify-e2e) is right.

Nit: the comment at .github/workflows/verify-e2e.yml:26 explains our own CLI's 2-hour minimum, which AGENTS.md asks us not to do.

Pushed fixes for the review findings above:

• ffee122 merge feat(verify): add the end-to-end test package and the verify-clerk-android skill #1046's fixes (kept this branch's deletion of E2ECleanupReceiver.kt over test(e2e): configure the e2e host from verify launch extras #1041's change to it)
• e8d70f6 ci(verify): drop the comment that explains our own CLI's throwaway minimum
