Closes R-4 and R-5 of the routing-defaults plan.
R-4: Strengths + CostWeight defaults for closed frontier models.
Cloud entries land in the same knownFamilyDefaults table as local
ones, with MaxComplexity intentionally left zero (cloud arms get
no complexity ceiling). CostWeight tuned per the plan's rationale:
claude-opus-4-7 → Planning/SecurityReview/Debug/Refactor, 0.3
claude-sonnet-4-6 → Generation/Refactor/Review, 0.7
gpt-5.5 → Planning/SecurityReview/Generation, 0.3
gpt-5.3-codex → Generation/Refactor/Debug/UnitTest, 0.6
gpt-5.2 → Orchestration/Review, 0.8
gemini-3.1-pro → Planning/Review/Orchestration, 0.5
gemini-3.5-flash → Boilerplate/Explain/Orchestration, 1.2
The 0.3 weight on frontier arms keeps them competitive on
SecurityReview / Planning despite $4+/Mtok; 1.2 on Gemini Flash
penalizes cost more so it only wins when cost is genuinely
decisive (boilerplate, explain).
Mechanism: extracted applyFamilyDefaults into defaults.go and call
it from Router.RegisterArm. Single source of truth — both local
discovery and the primary-provider path in cmd/gnoma/main.go now
flow through the same defaults application. Removed the duplicate
apply block from RegisterDiscoveredModels.
Legacy model IDs (claude-opus-4-20250514, gpt-4o, o3, gemini-2.5-pro,
etc.) intentionally do not match any table entry — keeps users on
pinned older models safe from imposed 2026 Strengths.
R-5: gpt-5.3-codex registration.
- internal/provider/openai/provider.go: added to fallbackModels
and inferOpenAIModelCapabilities (400K context, 32K output).
- internal/provider/ratelimits.go: gpt-5.3-codex and its dated
alias gpt-5.3-codex-2026-02-15 added with the same Tier 1
quotas as gpt-5.2.
Gemini 3.x (3.1-pro-preview, 3.5-flash, 3.1-flash-lite) was already
registered in both google/provider.go and ratelimits.go — no change
needed for that part of R-5.
Test coverage:
- ResolveFamilyDefaults table-driven across all 7 cloud entries
including prefix-sharing (gpt-5.5-pro → gpt-5.5 defaults,
gemini-3.1-pro-preview → gemini-3.1-pro defaults).
- Legacy IDs return !ok.
- RegisterArm applies cloud defaults end-to-end.
- User-supplied Strengths and CostWeight are not overridden.
- ID.Model() fallback works when ModelName is empty (test code
often constructs arms this way).
