test(e2e): cover model filtering and usage caveats

[SantiagoDePolonia]

Summary

• exercise OpenRouter inventory filtering through both admin and public model catalogs
• assert Gemini zero-token embedding rows carry the missing-usage cost caveat
• make the model-category smoke check non-vacuous and update the scenario count

Validation

• bash -n tests/e2e/manage-release-e2e-stack.sh tests/e2e/run-release-e2e.sh
• baseline matrix: 223/223 passed
• updated matrix: 223/224 passed; S119 received a transient upstream HTTP 429
• isolated rerun: S119 passed
• focused updated scenarios: S05, S218, and S224 passed
• pre-commit hooks passed

Summary by CodeRabbit

• New Features
  • Added OpenRouter inventory filtering to release end-to-end coverage, showing only free models by default.
  • Added validation for model categories and inventory counts.
  • Added coverage for Gemini batch embedding metadata and zero-token usage records.
  • Added verification that admin and public OpenRouter inventories consistently display only free models.
• Documentation
  • Expanded the release end-to-end scenario matrix to 224 scenarios.
  • Documented request metadata and cost-calculation considerations for Gemini batch embeddings.

📝 Walkthrough

Walkthrough

The release E2E stack now defaults OpenRouter inventory filtering to free models. Scenario documentation adds S224, strengthens S05 validation, extends S218 usage checks, and updates the scenario count to 224.

Changes

Release E2E coverage

Layer / File(s)	Summary
OpenRouter inventory filtering tests/e2e/manage-release-e2e-stack.sh, tests/e2e/release-e2e-scenarios.md	The stack sets OPENROUTER_MODEL_FILTER_INCLUDE to *:free when unset. S224 checks filtered admin and public OpenRouter inventories. The documented scenario count is 224.
Scenario validation and usage checks tests/e2e/release-e2e-scenarios.md	S05 requires a non-empty model-category array with valid category names and non-negative numeric counts. S218 sends request metadata and verifies zero Gemini tokens with the documented cost caveat.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to dabf8

This change adds end-to-end coverage and clarifies usage-cost assertions; the PR is merge-ready after normal checks, with no actionable merge-blocking risk remaining.

Poem

A rabbit sets the free-model gate,
While inventories validate their state.
S05 counts cleanly, S218 records,
Five new checks join the release boards.
The E2E burrow grows precise.

Confidence Score: 5/5

Safe to merge: the focused release-runner and provider-filter checks passed without identifying an actionable defect.

The new scenario parses, extracts into valid shell, and its filtered inventory behavior is covered by passing runtime tests. The unavailable local PostgreSQL command-line tool prevented a full live-stack run but did not produce a defect.

Files Needing Attention: None.

T-Rex Logs

What T-Rex did

• The release runner was extended to cover three scenarios (S05, S218, S224) and was validated to exit cleanly after the change.
• S224 was extracted via the release runner and syntax-checked; the script queries /admin/models and /v1/models, requires OpenRouter entries in both, and rejects models without the :free suffix.
• Focused provider inventory runtime tests showed free models remain visible while paid models are excluded.
• Attempting to start tests/e2e/manage-release-e2e-stack.sh with --build was blocked by the absence of psql, so the live HTTP scenario could not be run.
• The in-process E2E suite ran, but unrelated audit-log shutdown timeout failures were observed, not involving S224.
