fix(models): drop curated OpenRouter ids that are retired or no longer tool-capable

[jbbottoms]

Summary

Five of the 39 entries in OPENROUTER_MODELS no longer work. Checked against OpenRouter's live /api/v1/models (337 models):

Curated id	State
openrouter/elephant-alpha	retired, no successor
poolside/laguna-m.1:free	retired; family moved to laguna-s-2.1
tencent/hy3:free	free tier withdrawn
inclusionai/ring-2.6-1t:free	free tier withdrawn
openrouter/pareto-code	served, but supported_parameters is []

The first four fail the moment a user picks them.

The fifth is the worse one. openrouter/pareto-code is still served, so it selects and runs fine, and only fails when the agent tries to call a tool. In an agent framework that is a silent trap rather than an error.

Nothing caught this because every existing model test asserts against the curated list itself. That makes the list self-consistent, and says nothing about whether OpenRouter still serves what is in it.

The two :free removals

tencent/hy3 and inclusionai/ring-2.6-1t still exist as paid ids. I removed the :free entries rather than re-pointing them, because moving a user's free selection onto a paid id is a curation decision for you, not something a drift fix should do quietly. tencent/hy3 is already curated separately and is untouched.

Same reasoning for poolside/laguna-m.1:free: laguna-s-2.1 and laguna-xs-2.1 are live, but adding them is a new curation call rather than a repair.

Preventing recurrence

Adds tests/hermes_cli/test_openrouter_catalog_drift_live.py, opt-in and live in the same shape as the other *_live.py tests here:

HERMES_LIVE_TESTS=1 OPENROUTER_API_KEY=sk-or-... \
    pytest tests/hermes_cli/test_openrouter_catalog_drift_live.py -q

Live and opt-in on purpose: it asserts against a third-party catalogue that changes without us, so it must never be able to redden CI on someone else's deploy. It is a maintenance check run deliberately.

It checks the two failure modes separately, because they are not the same problem — one fails on selection, the other on first tool call.

Verification

• Skips clean with no opt-in — 2 skipped
• Passes live after this change — 2 passed
• Non-vacuous: run against the unfixed list it fails and names all five:

  AssertionError: OPENROUTER_MODELS lists ids OpenRouter no longer serves; a user picking one
  gets a failure: ['openrouter/elephant-alpha', 'poolside/laguna-m.1:free', 'tencent/hy3:free',
  'inclusionai/ring-2.6-1t:free']
  assert not ['openrouter/pareto-code']
  

• scripts/build_model_catalog.py regenerated — openrouter 39 → 34 models
• pytest tests/hermes_cli/test_model_catalog.py test_model_search.py test_ai_gateway_models.py → 30 passed
• ruff check → passed

• feat(models): add four Gemini models to the OpenRouter curated list #77159 [closed] best fix — (+21/-1) — n/a: Recorded best fix for [Feature]: OpenRouter curated list should include more Gemini models (BYOK users) #76732 at the Verify stage, adding four Gemini IDs to the curated source and manifest, but it restores 3.5 without a rationale against feat(models): Gemini 3.1 Pro + 3.6 Flash in OpenRouter/Nous catalogs; drop retired Qwen entries #73479's replacement decision. Despite the COMMENTED keep_open review, the contributor explicitly requested that rationale and the author accepted the objection and closed the PR in favor of a different approach, so reopening is not recommended.
• fix(models): drop curated OpenRouter ids that are retired or no longer tool-capable #77203 related — (+91/-29) — n/a: Removes four unserved IDs and one served-but-non-tool-capable ID from the curated source and manifest, updates the Tencent assertion, and adds an opt-in live test for service and tool-capability drift; this addresses catalog breakage rather than the request to expose more Gemini models.
• feat(models): let BYOK users opt into the full OpenRouter catalog #77254 best fix — (+165/-4) — n/a: Recorded best fix for [Feature]: OpenRouter curated list should include more Gemini models (BYOK users) #76732 at the Verify stage, adding a default-off openrouter.show_all_models option that preserves curated ordering, appends other live tool-capable models, filters non-tool models, and tests configuration and cache isolation.

Duplicates

#3756 and #3803 contain the same OpenRouter Gemini 3.1 additions; #3756 was closed after being incorporated into the more complete, merged #3803. The remaining PRs represent distinct catalog revisions, drift repair, or opt-in expansion rather than equivalent diffs.

Suggested consolidation

Keep #77203 open with a salvage path focused on the five removals and the opt-in live drift test, and keep #77254 open with its distinct salvage path as the recorded best fix for #76732's BYOK discovery problem. Leave #77159 closed rather than reopening it over the contributor's curation objection and the author's acceptance of that objection; #3756 is already superseded by merged #3803, while #34581 and #73479 remain merged historical baselines rather than closure candidates.
