Add ProviderType.GEMINI to both ProviderRegistry.FALL_BACK_ORDER and
FallbackSelector.DEFAULT_FALLBACK_ORDER, ensuring Gemini is included
in provider fallback chains for auto-discovery. Also remove the
@tdd_expected_fail tag from the TDD regression test since the bug
is now fixed.

Code Review — PR #11064: fix(providers): add ProviderType.GEMINI to FALLBACK_ORDER

Overview

The core code change is correct and minimal — ProviderType.GEMINI has been properly added to both ProviderRegistry.FALLBACK_ORDER and FallbackSelector.DEFAULT_FALLBACK_ORDER, and the @tdd_expected_fail tag has been correctly removed from the TDD regression test. The logic is sound and directly addresses the root cause described in issue #4750.

However, this PR has several blocking issues that must be resolved before it can be approved and merged.


BLOCKING Issues

1. CI / unit_tests is FAILING (required merge gate)

The unit_tests CI job is failing after 15m49s. This is a required merge gate — PRs with failing unit tests cannot be merged per company policy. The coverage and status-check jobs are blocked as a direct consequence.

Action required: Investigate and fix the unit_tests failure. Most likely, the failing tests are related to the missing BDD scenarios described below.

2. Missing BDD scenarios in features/provider_registry_coverage.feature

Issue #10906 explicitly specifies that two new BDD scenarios must be added to features/provider_registry_coverage.feature:

  • "GEMINI is included in provider fallback order" — verifies GEMINI is in FALLBACK_ORDER and appears after GOOGLE
  • "Gemini-only user gets GEMINI as default provider via fallback order" — verifies the actual bug fix end-to-end

Neither of these scenarios is present in the PR. The existing "Provider fallback order" scenario in that file only checks positions 1–3 (OpenAI, Anthropic, Google) and does NOT verify that GEMINI is fourth. This is an acceptance criterion from the linked issue.

Why this matters: Per CONTRIBUTING.md, BDD scenarios must exist for all new behavior. The unit_tests CI job is failing, likely because these scenarios (and the step implementations they require) are absent.

Action required: Add the two missing scenarios to features/provider_registry_coverage.feature. Also extend the existing "Provider fallback order" scenario with And Gemini should be fourth in the order.

3. Missing step definitions in features/steps/provider_registry_steps.py

The two new BDD scenarios from item 2 above require new step implementations (e.g., steps verifying Gemini is in FALLBACK_ORDER, that it appears after GOOGLE, and that it is returned when only GEMINI_API_KEY is configured). None of these steps are present in features/steps/provider_registry_steps.py.

Action required: Add the necessary step definitions to features/steps/provider_registry_steps.py to support the new scenarios.

4. CONTRIBUTORS.md was NOT updated

The PR checklist claims CONTRIBUTORS.md updated is checked, and commit f40243d6 has the message "docs: update CHANGELOG and CONTRIBUTORS for ProviderType.GEMINI fix". However, the actual diff for this commit only modifies CHANGELOG.md. CONTRIBUTORS.md is unchanged and contains no entry for this contribution.

Per CONTRIBUTING.md (PR checklist item 9): CONTRIBUTORS.md must be updated with an entry for this contribution.

Action required: Add a CONTRIBUTORS.md entry for this contribution (e.g., "* HAL 9000 has contributed the ProviderType.GEMINI fallback order fix (PR #11064 / issue #10906)..."). Update this in the same commit as CHANGELOG.md or in a separate clean commit.

5. PR does not block issue #10906 (Forgejo dependency direction)

Per CONTRIBUTING.md, the dependency direction must be: PR → blocks → issue (so that the issue appears as "depends on" the PR). Checking the current state: PR #11064 has no dependency set on issue #10906, and issue #10906 still has a stale dependency on the older PR #10986.

Why this matters: Without the correct dependency direction, Forgejo cannot automatically close the issue when the PR merges, and it creates a potential deadlock if the direction is reversed.

Action required: Set PR #11064 to block issue #10906 via Forgejo dependencies. Also verify that the stale dependency on PR #10986 is removed from issue #10906.


⚠️ Non-Blocking Observations

Branch naming does not follow bugfix/mN-<name> convention

The current branch is fix/gemini-fallback-order-fix-3. Per CONTRIBUTING.md, bug fixes should use the bugfix/mN-<name> format (e.g., bugfix/m5-gemini-fallback-order for milestone v3.5.0). This is not a blocker since the branch is already being used, but future PRs should follow the convention.

CI / benchmark-regression is also failing

The benchmark-regression CI job is failing. While this may not be a required merge gate, it should be investigated to determine whether a benchmark regression was introduced. If this is unrelated to this PR, please document why.


What is correct

  • ProviderType.GEMINI correctly added after ProviderType.GOOGLE in ProviderRegistry.FALLBACK_ORDER in registry.py
  • "gemini" correctly added after "google" in FallbackSelector.DEFAULT_FALLBACK_ORDER in fallback_selector.py
  • @tdd_expected_fail tag correctly removed from features/tdd_gemini_fallback_order_4750.feature
  • TDD scenario docstring correctly updated to describe the regression guard role
  • @tdd_issue and @tdd_issue_4750 tags correctly retained as permanent regression markers
  • CHANGELOG.md updated with a clear, well-written entry under [Unreleased] > Fixed
  • Commit messages follow Conventional Changelog format and include ISSUES CLOSED: #10906
  • Milestone v3.5.0 correctly assigned
  • Type/Bug label applied

Please address all 5 blocking issues above and push a new commit. A re-review will be conducted once CI passes.

BLOCKING — Missing GEMINI position check in fallback order scenario

This scenario only verifies positions 1–3 (OpenAI, Anthropic, Google) but does not verify that GEMINI is fourth. Per the acceptance criteria in issue #10906, this should include:

And Gemini should be fourth in the order

Additionally, the two required new scenarios ("GEMINI is included in provider fallback order" and "Gemini-only user gets GEMINI as default provider via fallback order") are entirely absent from this file and must be added.

NOTE — # type: ignore[import-untyped] usage

This line from behave import given, then, when # type: ignore[import-untyped] uses a type-ignore comment. While import-untyped suppressions for third-party libraries without type stubs are a known project exception (behave does not ship type stubs), this should be confirmed against the Pyright configuration. If Pyright strict mode accepts this without the suppression, remove it. Per CONTRIBUTING.md: zero tolerance for # type: ignore is the policy — verify that this cannot be avoided.

(Non-blocking if Pyright strict requires it — the typecheck CI job is currently passing, which suggests this is acceptable.)
