[NA] [GHA] chore: remove three permanently failing scheduled workflows

[jverre]

Details

Deletes three scheduled workflows that have been failing 100% of their runs for roughly six months: quickstart_guide_snippets_test.yml, test_docs_links.yml and documentation_cookbook_tests.yml. All three invoke test suites that no longer exist — 495e98ecdc ("Python E2E tests retirement", #4731, 2026-01-15) removed 67 files under tests_end_to_end/, including tests/QuickstartGuide, tests/Documentation/test_links.py and the shared requirements files. Two of them still fire daily at 12:00 UTC and fail every time, which is pure noise plus wasted runner time.

• quickstart_guide_snippets_test.yml — 100/100 failures, still firing daily. Failed at Install Test Dependencies from Jan 15 to Jul 20; cd6bee31a4 ([OPIK-7385] [GHA] chore: migrate CI Python tooling from pip/setup-python to uv #7538, uv migration) restored the requirements files, which advanced the failure to Run suite → file or directory not found: tests/QuickstartGuide.
• test_docs_links.yml — 100/100 failures, still firing daily. Same two-phase history, now failing at Run linkinator because it writes its CSV into the deleted tests_end_to_end/tests/Documentation/. Its intent is largely duplicated by documentation_preview_link.yml.
• documentation_cookbook_tests.yml — 100/100 failures; its schedule: trigger was already removed, so it has been dispatch-only and dormant since 2026-03-24.

Verified nothing else depends on them: no workflow, script, or doc references any of the three by filename or display name, and main has no required status checks configured, so no branch protection is affected. tests_end_to_end/test_requirements.txt is deliberately kept — installation_tests.yml still uses it in five places.

Change checklist

• User facing
• Documentation update

Issues

• Resolves #

AI-WATERMARK

AI-WATERMARK: yes

• Tools: Claude Code
• Model(s): Claude Opus 5
• Scope: Audited the last 100 runs of all 83 registered workflows to identify permanently-red and long-running CI, traced these three to their root-cause commits, and authored the deletion.
• Human verification: Author reviewed the audit findings and confirmed the decision to delete rather than restore these three workflows.

Testing

Deletion-only change; no code paths altered.

• pre-commit ran on the staged change set — all 42 hooks reported "no files to check" (correct for a pure deletion), including ⚙️ actionlint — github workflows.
• Confirmed the three files are gone and the remaining workflow count drops from 77 to 74.
• grep -rn across the repo for all three filenames and their name: display strings returns no remaining references.
• gh api repos/comet-ml/opik/branches/main/protection --jq '.required_status_checks.contexts' returns [], confirming none of these was a required check.
• Confirmed via grep that tests_end_to_end/test_requirements.txt still has a live consumer (installation_tests.yml) and was therefore not removed.

Documentation

No documentation changes needed — these are internal CI workflows with no user-facing surface and no references in the docs.

Follow-ups intentionally left out of scope:

• tests_end_to_end/integrations_requirements.txt is now orphaned (quickstart_guide_snippets_test.yml was its only consumer) and could be removed in a separate cleanup.
• installation_tests.yml is also 100/100 red for the same root cause and still fires daily; it is kept here by request and needs its own decision.
