Practice III — Engineering

AI Architecture

Six proprietary modules. In production. Operated under mandate.

Costantini & Partners does not license technology. The Consistory programme is authored in-house, in closed source, and deployed within client engagements. Modules replace categories of commodity vendor tooling.

The Practice

The contemporary advisory market trades in slide decks built on top of vendor software. The advisor is the interface; the substance lives elsewhere — at Salesforce, at HubSpot, at Adobe, at SendGrid. The structure is fragile because the value sits with the platform.

Consistory inverts this. The stack is authored, in closed source, in production. When an engagement requires a CRM with 156 endpoints, Parsifal is deployed. When transactional email at scale fails on commodity providers, Maestro takes over. When tracking restrictions threaten attribution integrity, Perseus moves the signal server-side. The advisory becomes the deployment.

The Six Modules

Each module is in active production. Each replaces a category of commodity vendor tooling. Each is authored under the Consistory programme.

M·01

CRM Core

Parsifal

WordPress-native CRM with Electron desktop client. The system that runs the client engagement.

Endpoints 156 REST endpoints across ten modules
Modules leads, audience, calendar, ticketing, multichannel inbox, landing builder, automation, staff, media, configuration
Stack PHP · WordPress REST · Electron
State In production across multiple mandates

M·02

Email Engine

Maestro

Transactional and lifecycle email engine. Replaced SendGrid in production.

Flows 19 automated lifecycle flows
Stack SMTP · CRON · templating
Features A/B preview, deliverability hooks, segmentation
Replaces SendGrid, Postmark, Mailgun (commodity tier)

M·03

Conversational Layer

Parsifal WA

WhatsApp Business agent with human-priority routing and full audit.

Stack Node · Baileys · WhatsApp Business · FSM
Latency 3-minute human-priority window
Features Knowledge-base routing, conversation pause states, full audit
Use case High-stakes customer interaction at scale

M·04

Tracking Suite

Perseus

An 884-line tracking layer paired with GTM server-side. Stealth dual-pixel proxy.

Coverage Meta + TikTok dual-pixel proxy
Stack JS · GTM SS · CAPI
Features Bot detection, dedup, exit-intent telemetry, scroll fallback
Resilience HttpOnly-cookie ID-fallback environments

M·05

Data Enrichment

Hans Sachs

Server-side data reconciliation. Enriches signals with ga_sid, _fbp, _fbc, _ttp across ad-blocker-resistant environments.

Stack PHP · BigQuery-ready
Coverage 19 ad-blocker-resistant environments
Output Reconciled signals delivered to BigQuery / Snowflake

M·06

Operating Layer

Verdi · Nabucco · Omero

Three-component operating layer: unified inbox, autopilot scheduler, landing-page builder.

Verdi Unified-inbox IMAP/SMTP integrated with Parsifal
Nabucco 5-minute autopilot cron, redeployed by tick
Omero Landing-page and template builder linked to lead audiences
Stack IMAP · CRON · CMS

Modules are proprietary, in active production, and not externally licensed.

Method

LLM-assisted engineering as method, not novelty.

Consistory is built using deliberate LLM-assisted engineering. Every module is specified before it is coded: contracts written, endpoints declared, edge cases enumerated, before a line is generated. The model accelerates implementation; it does not replace architecture.

Defensive iteration. Every release passes through five rollback rounds with observable state, so that even when fixes are walked back, the synthetic fallback remains stable. The cross-stack fluency — PHP/WordPress for the CRM core, Node/Baileys for WhatsApp, JS at the tracking layer, Electron for desktop, SQL per analytics — is a coherence choice.

A mandate, not a license.
