test(e2e): verify full repository Git history

[saurya]

Summary

• Enable the authenticated OHE member's full Git history setting from App settings.
• Launch a configured repository conversation and verify git rev-list --count HEAD meets the configured multi-commit minimum.
• Restore the original disabled toggle after deleting the conversation.
• Use selectors and routes checked against OpenHands/enterprise@d603dc3b4e85b249638154c0016c5f082a76989f and OpenHands/OpenHands@2e1502f39d8f7357fca35c6c18cc2c0dadcf0da3.

Environment contract

• BASE_URL: required non-production OHE target.
• e2e_tests/fixtures/auth.json: authenticated OHE member storage state with full Git history initially disabled.
• TEST_FULL_HISTORY_REPOSITORY: readable repository with multiple commits.
• TEST_FULL_HISTORY_PROVIDER: configured provider (github, gitlab, azure_devops, bitbucket, or bitbucket_data_center).
• TEST_FULL_HISTORY_MIN_COMMITS: integer minimum expected from the repository, at least 2.
• A working LLM profile capable of running the deterministic git rev-list prompt.

Missing configuration throws actionable errors; the test does not skip and does not print credentials.

Cleanup

A finally block deletes the created app conversation and restores the original git_full_clone setting through the authenticated settings API, even after assertion failure. The source repository is never modified.

Validation

• npm ci was completed once for the shared harness dependency tree.
• npm run lint -- tests/member-full-git-history.spec.ts
• BASE_URL=https://release-under-test.invalid npx playwright test tests/member-full-git-history.spec.ts --project=chromium --list
• One added spec file, one top-level test, one commit parented directly to current main.
