Phase 03 Plan 03: Tier 5 Infrastructure/Gateway Providers Summary

Added 11 Tier 5 infrastructure/gateway provider YAMLs (OpenRouter, LiteLLM, Cloudflare Workers AI, Vercel AI Gateway, Portkey, Helicone, Martian, Kong, BricksAI, Aether, Not Diamond) using documented prefix regex where available and keyword-only detection otherwise, satisfying PROV-05.

What Was Built

• High-confidence prefix regex for providers with documented key formats:
  • OpenRouter: sk-or-v1-[a-f0-9]{64} (high) + sk-or-[A-Za-z0-9]{40,} (medium)
  • Helicone: sk-helicone-[a-z0-9]{7}-[a-z0-9]{7}-[a-z0-9]{7}-[a-z0-9]{7} (high)
• Low-confidence patterns with strong keyword anchors:
  • LiteLLM: generic sk- with LITELLM_MASTER_KEY / LITELLM_PROXY_API_KEY keywords
  • Cloudflare Workers AI: generic 40-char token with CF env-var keywords
• Keyword-only detection (no patterns field) for 5 providers without documented public key formats: Martian, Kong, BricksAI, Aether, Not Diamond. Relies on the Aho-Corasick keyword pre-filter established in plan 01-02.
• Verify endpoints populated where the provider exposes an auth-check route (OpenRouter, Cloudflare, Portkey, Helicone); empty stubs for others.

Tasks Completed

Task	Name	Commit
1	OpenRouter, LiteLLM, Cloudflare, Vercel, Portkey, Helicone YAMLs	a9ee75e
2	Martian, Kong, BricksAI, Aether, Not Diamond YAMLs	c8d326c

Verification Results

• go test ./pkg/providers/... -count=1 — PASS
• go test ./pkg/engine/... -count=1 — PASS
• grep -l 'tier: 5' providers/*.yaml | wc -l — 11
• All 22 files dual-located (providers/ + pkg/providers/definitions/) and byte-identical.
• OpenRouter sk-or-v1- prefix present; Helicone sk-helicone- prefix present; LiteLLM LITELLM_MASTER_KEY keyword present.
• Martian, Kong, BricksAI, Aether, Not Diamond all omit patterns: field (verified via grep -L).

Deviations from Plan

None — plan executed exactly as written.

Known Stubs

Verify endpoints for LiteLLM, Vercel AI Gateway, Martian, Kong, BricksAI, Aether, and Not Diamond are intentionally empty (no public verification endpoint). These satisfy schema requirements and will be wired by Phase 5 verification engine only if/when endpoints become documented. This matches the keyword-only detection strategy — presence, not liveness, is what these providers assert.
