JSONFIRST · GOVERNANCE LAYER

Two governance layers. Eight killer features.

JSONFIRST combines behavioral governance (personas) and operational governance (modes) to create a multi-layered control plane your LLMs can't bypass.

8 Killer Features that set us apart

Deterministic JDON filter

ZERO false positives

Blocks are computed by validated regex and patterns — not by LLM. Same result every run, traceable, auditable, no surprise blocks.

100% reproducible

Deterministic + LLM cross-verification

Dual engine

First pass: 91 deterministic UCE patterns detect fraud, bypass, splitting. Second pass: LLM enriches with business context. Both results are reconciled.

2 layers · 0 blind spots

91 UCE patterns · Pre-execution block

Hallucination Lock

Before any agent executes anything, the engine verifies policy_constraint, thresholds, vendor whitelists, IBAN consistency. Hallucinations are blocked BEFORE action.

Pre-exec · No rollback needed

Unique in market — Persona + Governance

Implant × Mode Fusion

An implant (CEO, Doctor, Lawyer, CFO…) drives the TONE and STRUCTURE. A mode (NOCODE_SAFE, SAFE_OPS…) drives SEVERITY. Combined, they produce persona-aware + compliance-aware output.

6 implants × 8 modes = 48 combinations

SHA-256 + HMAC · AI Act Art. 14

Immutable Decision Log

Every escalated decision is SHA-256 hashed, HMAC-SHA256 signed, chained to the previous entry. Impossible to modify history without breaking the chain. Legal export available.

AI Act compliant · 7-year retention

3-5 independent LLM runs

Majority Vote

On critical transactions (>€5,000, DSP2, CFO fraud), the engine runs 3 or 5 independent runs. Final verdict validates only if majority converges. Eliminates LLM variance.

99% consensus · 0 single-point-of-failure

NOCODE_SAFE_LIGHT <50ms without LLM

Deterministic latency

For daily N8N/Zapier workflows, no LLM needed. 3 critical guards run in <50ms in pure regex. Perfect for high volume without blowing up the bill.

<50ms · 0 LLM tokens consumed

Signable · Certified · 7 years

White-label PDF Audit Trail

Every decision generates a PDF with your branding (logo, colors, signature). DPO/compliance compliant. Exportable, digitally signable, archivable for 7 years.

Client branding · SHA-256 sealed
