Streams 04 & 05 · Epistemic Observability, FeynmanCheck™ & Cepeda-Ebbinghaus™ API
Plain-English translation: Verifies whether an explanation or prompt actually covers the required concepts in under 2 milliseconds at $0 LLM token cost, and schedules optimal review intervals.
1. Purpose & Architectural Role
Powers both enterprise epistemic observability (measuring Time to Executive Decision and catching prompt underspecification in <2ms before burning GPU tokens) and our flagship clinical showcase GeekVitals™ (verifying NCLEX/MCAT/CFA conceptual mastery at $0 LLM grading cost and locking spaced-repetition intervals to exam dates via Cepeda-Ebbinghaus™).
Cross-references: System Architecture · GRAMS™ Manifold & GRMA · 3 Runtime Shells (FastAPI, Go, Rust).
2. Request Schema (POST /v1/feynman/check)
All requests require Content-Type: application/json and an Argon2id-scoped bearer header (Authorization: Bearer tw_live_...) issued via /v1/auth/argon2-verify.
| Field | Type | Requirement | Specification |
|---|---|---|---|
candidate_explanation | string | Required | The user response, executive summary, or clinical rationale to evaluate. |
target_concept_id | string | Required | Canonical concept node (e.g., sepsis_lactate_clearance, gaap_capex_restatement). |
exam_or_audit_horizon_days | integer | Optional (/v1/pacing/cepeda) | Days remaining until target credentialing exam or compliance audit. |
3. Response Schema
Responses are deterministic JSON payloads returned with X-Powered-By: Quantsultant-GRAMS-Engine/2.5ms-Edge and zero customer payload retention at rest.
| Field | Type | Deterministic Guarantee |
|---|---|---|
status | string | STREAM_ACTIVE deterministic execution confirmation. |
route | string | /v1/feynman/check or /v1/pacing/cepeda. |
execution_ms | number | Sub-2.5ms local deterministic NLP execution time with $0 LLM token burn. |
payload_echo | object | Evaluated concept mastery parameters and retention schedule. |

5. Versioning, Error Codes & Rate Limits
| Parameter / HTTP Code | Status / Value | Operational Behavior & Recovery |
|---|---|---|
| API Version | v1 (Engine 2.5.0) |
Pinned schema contract across FastAPI, Go 1.22, Native Rust, and Cloudflare Edge. Pre-patent charter waitlist active. |
200 OK |
GRAMS_VERIFIED_PASS |

One Verification Core · Two Direct Paths
API access is gated while we complete utility patent filings and IP legal structuring. Investors can start a direct SAFE & data-room conversation with Garrick Pinon; technical evaluators can reserve a gated tw_live_... API slot or 48-hour blind dataset proof of value.
