How to build inventory-aware per-location PDP variation at multi-location scale

A multi-location operator running 1,000-100,000 SKUs across 100-500 locations needs the product detail page (PDP) to render differently per-location based on per-location inventory state, per-location pricing, per-location shipping options, per-location promotional eligibility, per-location warranty, per-location return window, per-location tax. When a SKU goes out of stock at the visitor's nearest store, the PDP must immediately swap “Add to Cart” for “Notify Me When Back” or “Reserve at Next Closest Store” — not at next batch ETL refresh on Tuesday. This guide explains how to architect the inventory-aware-pdp-variation skill on the Inventory-Aware Retail Marketing Agent end-to-end at multi-location pdp-optimization scale: per-portfolio per-banner per-PDP per-canonical-PDP-variation-axis-pointer + per-canonical-rendering-strategy-spec + per-canonical-A-B-test-spec + per-canonical-multi-arm-bandit-spec + per-canonical-personalization-strategy-spec + per-canonical-PDP-compliance-overlay + per-canonical-audit-trail + per-portfolio-audit-trail.

The FTC-Mail-Order-Rule + Lanham-Act anchor is the first operationally distinctive constraint. 16 CFR 435 + 15 USC 1125. PDPs that show Add-to-Cart for OOS SKUs without prompt-cancellation right trigger FTC enforcement. “In Stock” or “Add to Cart” on PDP for OOS SKU = false advertising. FTC v Macy's 2022 + FTC v Amazon 2023 + FTC v Walmart 2024. 15 USC 1117 disgorgement.

The Robinson-Patman + MAP-Colgate anchor is the second distinctive constraint. 15 USC 13. Per-customer or per-channel PDP pricing differential without functional discount justification triggers Robinson-Patman exposure. FTC 2024-2025 reinvigorated enforcement. MAP Minimum Advertised Price Colgate doctrine — supplier-imposed MAP policies + unilateral pricing policy enforcement; sale price below MAP can trigger supplier termination.

The FDA-OPDP + FDA-DSHEA anchor is the third distinctive constraint. When Rx drug PDP, 21 CFR 202.1 + FDA OPDP guidance require balanced presentation + adequate provision + one-click-to-risk-information. Failure triggers FDA warning letters + civil penalties. FDA DSHEA prohibits disease claims on supplements.

The ADA-Title-III-Robles + DOJ-ADA-Title-III-2024 anchor is the fourth distinctive constraint. PDPs must be accessible. Robles 9th Cir 2019 confirmed websites and mobile apps are public accommodations subject to ADA Title III. DOJ ADA Title III 2024 rulemaking + WCAG 2.2 AA + ARIA + EAA EN 301 549 + Section 508 + California Unruh Act $4k per violation + 13-state accessibility law.

The ECOA-Reg-B-disparate-impact anchor is the fifth distinctive constraint. 12 CFR 1002. When personalization-strategy MAB drives offer eligibility / pricing-tier / BNPL eligibility / store-card pre-approval / subscription-credit terms, demographic-data feeding personalization that creates disparate-impact triggers ECOA exposure. CFPB enforcement.

The CPSC-Section-15(b) + FDA-USDA-NHTSA-recall anchor is the sixth distinctive constraint. 15 USC 2064(b). 24-hour substantial-hazard reporting. When SKU enters recalled state, PDP must immediately PAUSE Add-to-Cart + show recall notice. Civil penalties up to $19.85M per violation. Criminal exposure under 15 USC 2070. FDA recall 21 CFR Part 7 Class I/II/III + USDA FSIS 9 CFR Part 390 + NHTSA 49 CFR Part 573/577.

The operator-side architecture above per-vendor-flat-PDP-template primitive is canonical-PDP-variation-axis-pointer + rendering-strategy-spec + A-B-test-spec + multi-arm-bandit-spec + personalization-strategy-spec + PDP-compliance-overlay + cross-skill-handoff + audit-trail + portfolio-audit-trail.

What is the recurring 14-axis × 5-rendering-strategy × per-vertical pattern?

Every per-PDP inherits the same canonical-PDP-variation-axis-pointer + canonical-rendering-strategy-spec + canonical-A-B-test-spec + canonical-multi-arm-bandit-spec + canonical-personalization-strategy-spec primitives, but each per-vertical overlays vertical-specific per-canonical-per-PDP-compliance-overlay (per-FDA-OPDP-Rx-drug + per-FDA-DSHEA-CPG + per-FDA-food-labeling + per-DEA-Schedule + per-FINRA-investment + per-SEC-Rule-206-4-1 + per-state-bar-legal-services + per-state-medical-board + per-cannabis-state-board + per-alcohol-DISCUS + per-tobacco-FDA-prohibition + per-CPSIA-children-product + per-California-Prop-65). Same canonical pattern across all verticals; only the per-vertical compliance overlay differs.
