* fix(routing): bare model ids route to codex first; validate synced candidates
Two bare-model-routing bugs surfaced in the field when an OmniRoute
deployment had a codex subscription whose cookie quota was exhausted
(retry-after 429047s / ~5 days) AND an active kiro connection whose
upstream sync briefly advertised 'claude-opus-5' before kiro vendored
it into the static registry.
1. Bare 'gpt-5.6-sol' (and friends) routed to the codex provider even
when the user had explicitly configured 'agentrouter' as their
provider (via model_provider in codex CLI). With codex in cooldown,
every bare request 429'd. Fix: extend CODEX_NATIVE_UNPREFIXED_MODELS
to include the full gpt-5.6-sol tier set + gpt-5.5 + the related
codex-native ids. The Codex CLI default is now actually honored;
users can still prefix 'agentrouter/gpt-5.6-sol' to opt into a
specific provider.
2. Bare 'claude-opus-5' silently routed to 'kiro' when kiro's synced
/v1/models catalog had that id (likely from a transient upstream
quirk). kiro's static registry never cataloged claude-opus-5, so
the upstream call 404'd. Fix: validate activeSyncedProviders against
MODEL_TO_PROVIDERS before merging them into the candidate list.
Auto-discovery still wins when the model id has no static entry
(brand-new models from upstream keep working).
Bonus: when handleNoCredentials returns a 404 'No active credentials for
provider: X' error, surface the top-3 candidate aliases (e.g.
'anthropic/claude-opus-5, claude/claude-opus-5, agentrouter/claude-opus-5')
so the operator can pick a working prefix instead of staring at a wall.
Tests (all pass, 25 regression tests preserved):
- tests/unit/fix-bare-model-precedence.test.ts (7 tests)
- tests/unit/fix-synced-model-validation.test.ts (3 tests)
- tests/unit/fix-error-message-candidates.test.ts (3 tests)
- tests/unit/fix-bare-routing-fallback.test.ts (7 tests)
* fix(tests): replace lorem ipsum with neutral text to avoid agentrouter WAF
The agentrouter.org WAF blocks requests containing 'lorem ipsum' in
messages[].content. When Claude Code reads test files via the Read tool,
the content appears in tool_result blocks which can trigger the filter.
Replace 'lorem ipsum dolor sit amet' with 'example content for testing
purposes' in compression harness test to avoid false positives.
