EXECUTIVE BRIEF // ADR-0002 FIXED-SCOPE PILOT 2 Principal-Led Pilot Slots / Month

14-Day AI Governance & Seam Charter Pilot

Isolate One High-Friction Workflow. Lock main Read-Only. Prove ROI in 14 Days.

PRINCIPAL ARCHITECTURE GUARANTEE ($15,000 - $25,000 USD · Fixed discretionary fee (scoped in 20 minutes; zero open-ended T&M retainers))

"We put a Golden Master around one named high-friction workflow, enforce read-only main isolation and custom AST invariants underneath your existing coding tools, and hand your team permanent ownership of the verification suite plus a written Go/No-Go Extraction Blueprint. Fixed price."

14-Day Fixed Execution Schedule (Zero Sprint Disruption)

DAYS 01 - 03 · PHASE 01 // BASELINE & BLAST-RADIUS MAP

AST Dependency Graph & Retry-Burn Audit

We map circular module coupling, shared-library divergence, and agent token-thrash hotspots across one named production repository without slowing active sprint delivery.

✓ Complete AST dependency boundary map of the selected module seam
✓ Agent retry-burn & multi-path code divergence baseline scorecard
✓ Locked 14-day pilot boundary charter signed off with Engineering Lead

DAYS 04 - 10 · PHASE 02 // CONTAINMENT & CUSTOM INVARIANTS

Read-Only main, Worktree Sandboxes & Domain Probes

We install non-invasive pre-tool and pre-merge safety rails underneath your existing coding agents (Claude Code, Cursor, Copilot, Windsurf) inside disposable Git worktrees.

✓ Physical read-only main protection with isolated task worktree sandboxes
✓ Golden Master behavioral characterization harness around the target seam
✓ 3 to 5 custom compiled AST & domain unit-lock probes (~4ms to 24ms execution)

DAYS 11 - 14 · PHASE 03 // CRYPTOGRAPHIC RECEIPTS & HANDOVER

Audit Provenance, Team Enablement & Go/No-Go Blueprint

Every verified merge emits a tamper-evident Git Notes release receipt. Your engineers keep 100% of the harness, sensor probes, and written Step 2 Extraction Blueprint.

✓ Cryptographic Git Notes audit receipts wired into CI/CD release branches
✓ Live 60-minute engineering handover & operational runbook walkthrough
✓ Written Architectural Feasibility & Extraction Assessment (Go/No-Go)

Representative Custom AST & Domain Unit-Lock Invariants

Multi-Agent SaaS & Scaleups (10 - 150 Devs)

Failure Mode: Agents invent 6 incompatible retry wrappers, shadow shared interfaces, or silently weaken failing unit tests to force green diffs.

Deterministic Lock: Canonical Singularity AST probes, test-deletion blocks, and spec-vs-code separation stop duplicate paths inside disposable worktrees before PR review.

AEC, Civil, Estimating & Physical Engineering

Failure Mode: Stochastic edits mix imperial/metric units, mutate quantity-takeoff rounding tolerances, or alter load-bearing calculation formulas.

Deterministic Lock: Compiled unit-lock invariants and Golden Master tolerance fixtures reject dimensional or precision drift in milliseconds.

Fintech, Healthcare & Regulated Enterprise

Failure Mode: Security and compliance teams veto AI velocity over cloud data exfiltration, unverified prompt rules, and missing change provenance.

Deterministic Lock: Zero-telemetry static binary execution inside your VPC, CapBAC capability leases, and cryptographic Git Notes release receipts per commit.

Procurement, Security & Scope Boundaries (CFO & CISO Fast-Pass)

Included in Fixed-Scope Charter

✓ Direct execution by Principal Systems Architect Mark Gantlett (25 years enterprise systems architecture)
✓ Works underneath your current coding tools (Claude Code, Cursor, GitHub Copilot, Windsurf) with zero workflow rip-and-replace
✓ 100% inside your Git hosting and VPC perimeter with zero external source-code telemetry
✓ Permanent perpetual ownership of all Golden Master tests, AST probes, and architectural runbooks

Explicit Non-Goals (Zero Scope Creep)

✕ No UI Rewrites: Frontend presentation layers remain untouched during the 14-day seam pilot
✕ No Cloud Re-Platforming: Operates inside your existing AWS, GCP, Azure, or on-premise CI stack
✕ No Historical DB Migrations: Existing schemas are wrapped safely via Golden Master seams without risky data rewrites
✕ No Open-Ended Consulting Lock-In: Fixed fee, fixed 14-day calendar boundary, explicit written Go/No-Go exit
