THE AGENTIC VERIFICATION ENGINE • HARNESS L4

Review Evidence,
Not Diffs.

The autonomous Spec-Driven Development (SDD) engine. We elevate developers into sovereign Tech Leads of ephemeral silicon pods—enforcing BDD contracts, AST blast-radius guards, and deterministic verification before code ever touches production.

❯ /ready4dev received on GitHub Issue #42: "feat(auth): add OAuth2 PKCE verification"

📐 [SDD Spec] Locking SPEC-42 with 3 BDD acceptance scenarios and strict Pydantic contracts

🐳 [Sandbox] Spawning isolated ephemeral container (cgroup limits: 1.0 CPU, 2048m RAM)

❌ [Red Loop] pytest tests/acceptance/test_spec_42.py -q --tb=short ➔ 3 FAILED (as expected)

🔨 [Implementer] Applying surgical code changes to target files [src/auth/pkce.py]...

✅ [Green Loop] pytest tests/acceptance/test_spec_42.py -q --tb=short ➔ 3 PASSED in 14ms

🛡️ [AST Guard] Analyzing AST risk: 0 dangerous calls (`eval`/`exec`), 2 files modified (< 10 file limit) ➔ SAFE

💸 [FinOps] Task consumed 84,210 tokens (73.6% prompt cache) ➔ $0.0240 USD (~R$ 0,14) [Circuit Breaker: OK]

🚀 [Pull Request] PR #88 created with full BDD verification proof. Card moved to In Review.

Engineered for Verification Rigor

Traditional AI assistants guess and generate. Ouroboros contracts and proves.

📐

Contract-First SDD

No silicon agent touches production code without a frozen contract. The engineer acts as sovereign Tech Lead, stamping BDD acceptance criteria via /ready4dev before implementation begins.

🛡️

AST Blast Radius Guard

Compiler-level Abstract Syntax Tree (AST) inspection actively audits every patch before commit. If an agent attempts to touch unauthorized sensitive paths or exceed blast radius limits, execution freezes instantly.

💸

Bicurrency FinOps Guard

Avoid compounding context snowballs. Our deterministic Path Sanitizer, Output Truncator, and hard budget Circuit Breaker (in USD and BRL) ensure tasks never cost more than pocket change.

🪆

Matryoshka Auto-Harness

Onboarding legacy or alien repositories? Ouroboros executes harness-score, generates canonical AGENTS.md constraints, and establishes the testing fence before writing features.

🐳

Shared-Nothing Topology

No central monolithic worker. One project equals one dedicated pod with its own isolated memory tiers, local SQLite FTS5 index, and zero cross-tenant contamination.

🔄

Closed-Loop OTel Recovery

Catch exceptions directly from production via native OpenTelemetry OTLP receiver. Ouroboros reproduces the stacktrace in RED, repairs the fault in GREEN, and opens the PR autonomously.

Reviewing Diffs vs Reviewing Evidence

Why modern engineering teams can no longer afford unconstrained code generation.

Capability	Legacy Copilots	Black-Box Agents (Devin)	Ouroboros Engine
Review Model	Human reviews raw diffs	Human reviews video/logs	Human reviews BDD verified proof
Code Privacy	Exposed to vendor cloud	Third-party proprietary VM	100% Sovereign (Runs in your Docker/Swarm)
Scope Protection	None (Agent hallucination)	Opaque heuristics	Deterministic AST Blast Radius Guard
Cost Control	Unpredictable token burn	$500/month seat lock-in	Hard Circuit Breaker ($0.02 - $0.50/task)
Architecture Seam	No formal contracts	Chat-based guesswork	Spec-Driven Development (SDD / BDD)
