Living architecture
Turn a changing retail technology estate into an explorable system map—services, symbols, dependencies, owners, models and the evidence horizon behind every answer.
PROOF SURFACECurrent-tree evidence + indexed history
Prepared for Walmart + Walmart Global Tech
Give every retail system and agent an evidence layer.
PX connects Walmart's developer platforms, models, agents, services and operational workflows to the exact source that makes a claim defensible—so complex systems can move faster without becoming impossible to inspect.

01 / THE GAP
Agentic retail needs an evidence control plane.
Walmart already has DX AI Assistant, Code Buddy, Element, Luminate, Sparky and agentic fulfillment systems. The harder problem is proving which code, data, model, policy and operational boundary made an answer or action defensible after the estate changes.

02 / WHAT PX CHANGES
One scan. A living retail technology atlas.
PX combines graph intelligence, semantic retrieval and documentation authority while exposing what it inspected, where the index ends and what remains unknown.
02
Cross-platform impact
Trace one consequential change across storefronts, fulfillment, inventory, data contracts, agent workflows and operational boundaries without losing the caller or confidence level.
PROOF SURFACEBounded continuations, not search dumps
03
Developer intelligence that compounds
Ground DX assistants and Code Buddy in a reusable evidence graph so repeated questions preserve their inspected source, decision and falsifier.
PROOF SURFACEQuestion → symbol → path → receipt
04
Agent review with receipts
Give platform, security and business reviewers the exact route, model, policy, data horizon, uncertainty and next verification step behind an agent decision.

04 / THE FIRST MOVE
Prove it in six weeks.
Start with one bounded Global Tech service family or developer workflow. Keep PX read-only, exclude customer data, run it in Walmart-controlled infrastructure and compare real investigation outcomes with the current method.
W01–02Connect + baseline
Index one estate and freeze its initial evidence horizon.
W03–04Run real questions
Use architecture, incident, documentation and agent-review cases.
W05–06Measure + decide
Compare speed, recall, reproducibility and reviewer effort.
SOURCE DISCIPLINE
The pitch carries its evidence.
