The 4-skill bundle on the save-offer-library-management agent

Catalog

Maintain unified offer library across vendor surfaces (Recharge discount rules + Bold offers + Loop + Skio + OrderGroove + Smartrr + Stay AI + Chargebee Coupons + Stripe Coupons + Shopify Discounts + Voucherify + Talon.One + Cordial + Klaviyo Coupons + PostScript Offers + Attentive Offers + Yotpo Loyalty + LoyaltyLion + Smile.io + Antavo). Per-offer canonical record covers offer ID + type (percent-off + dollar-off + pause-cycle + downgrade-tier + bonus-product + gift-bundle + charity -match + replenishment-reminder + education-content + customer-success-call + account-manager-outreach + retention-specialist-call + win-back-survey) + content template + asset CDN URL + metadata + source-vendor pointer + version pointer + effective date + revocation date + claim substantiation pointer + sibling-handoff pointer to #518 save-flow propensity.

Eligibility

Evaluate per-subscriber per-offer applicability via operator-counsel-approved rule registry: LTV decile, tenure cohort, acquisition channel, vertical, product line, tier, state residency (per-state pricing disclosure + per-state ARL alignment), country residency (per-country tax + return policy + cancellation rule), loyalty tier, payment method, billing frequency, shipping ZIP, cancellation-reason cluster (sibling #514), prior redemption count. Per-rule confidence tier and explainability. Probabilistic enrichment is bounded by operator-counsel-defined confidence band and disabled entirely when sensitive scope reached.

Stack

Operator-counsel-approved stack-conflict resolution across per-product + per-cart + per-subscriber stack caps. Per-vendor conflict resolution (Recharge stack vs Shopify stack vs Loyalty stack). Per-loyalty-program + per-referral-program conflict. Per-MAP per-product floor enforcement. Best-of-stack vs additive-stack chosen per operator-counsel policy. Explainability trace per stack decision documents which offers combined, which were suppressed, and why. The trace is the substantiation record for state-AG and FTC review.

Audit

Per-offer canonical record (offer ID + version pointer + claim substantiation pointer + effective + revocation date + per-state disclosure script pointer + per -vertical regulator scope tag + operator-counsel signoff). Per-redemption canonical record (redemption ID + subscriber tokenized + offer ID + version pointer + eligibility decision trace + stack decision trace + margin impact + per-state disclosure shown + substantiation pointer at redemption time). WORM storage. Per-record retention for FTC Section 5 substantiation defense + Robinson-Patman defense + state-AG enforcement + class-action discovery + EU AI Act supervisory authority + audit committee + external counsel review.

The 5-anchor compliance overlay

Anchor 1 — Robinson-Patman + MAP Colgate doctrine + FTC Section 5 substantiation + comparative-claim discipline (operationally distinctive)

Save-offer governance is a price-and-claim regime. Robinson-Patman Act 15 USC 13 prohibits price discrimination between competing resellers; FTC indicated renewed enforcement interest starting 2022. MAP Colgate doctrine (United States v Colgate 1919) draws the line between unilateral pricing policies (permitted) and resale price maintenance agreements (per se illegal under Sherman Act 1). FTC Section 5 substantiation doctrine (Pfizer 1972 reasonable-basis) governs every offer claim including comparative -savings claims. Pom Wonderful v FTC (2013) and Bayer Aspirin (2015) established discipline on comparative claims that extends to comparative price claims (claim of save 50 percent must be substantiable). FTC Mail Order Rule 16 CFR Part 435 covers order fulfillment + cancellation rights when offer involves mail or online order. FTC Fake Review Rule 16 CFR Part 465 (October 2024) applies when offer surfaces with social proof. FTC Endorsement Guides 16 CFR Part 255 apply when offer uses testimonial language. Per-state UDAP + per -state pricing-and-discount disclosure cover the regular price vs sale price + duration of offer + auto -renewal disclosure at offer time. Operationally distinctive frame: the library is the substantiation register, per-offer version pinning is what makes the register useful at audit time.

Anchor 2 — FTC Click-to-Cancel + multi-state ARL + Massachusetts AG v Sirius XM (pairs with #514 + #518)

FTC Click-to-Cancel Rule 16 CFR Part 425 (effective 2024-2025) + multi-state Automatic Renewal Laws (California Bus and Prof Code 17600-17606 + NY GBL 527-a + Vermont Act 110 + Colorado HB 21-1239 + Illinois ARL HB 4422 + Hawaii Act 218 + 6 additional state ARL statutes) + Massachusetts AG v Sirius XM 2017 ($3.8M settlement over difficult cancellation). Sibling #514 LLM cancellation-reason clustering + #518 save-flow propensity-scored offer selection consume this library; the library is the substrate that makes the consumer skills defensible.

Anchor 3 — Per-vertical product-category regulators

Magnuson-Moss Warranty Act 15 USC 2301 when offer affects warranty + state lemon laws. COPPA 15 USC 6501 when minors scope. California Proposition 65 when restricted-substance product. State cannabis Metrc tracking when cannabis SKU (Washington WSLCB Leaf Data + California METRC + Colorado MED + Oregon CTS + additional state programs). Alcohol DISCUS tied-house rules when alcohol SKU (per-state ABC + federal TTB). FDA Tobacco Control Act when tobacco SKU. FDA + DSHEA when dietary supplements. Per-vertical scope feeds Catalog metadata + Audit retention.

Anchor 4 — CCPA + CPRA + state-comprehensive-privacy + GDPR + WA MHMDA

CCPA + CPRA + 17-state-comprehensive-privacy + GDPR + Washington My Health My Data Act 2024 when offer scope intersects health. DSAR overlay across offer -redemption history + per-subscriber right-to-be -forgotten propagation across vendor substrate including downstream consumers (#514 + #518). Per -subscriber consent posture verified before offer delivery channel selection.

Anchor 5 — EU AI Act Article 50 + 13 + 14 + 15 + 22 + NIST AI RMF + ISO 42001 + per-vendor LLM zero-retention

EU AI Act Article 50 transparency for AI-generated content when offer copy is AI-drafted + Article 13 transparency + Article 14 human oversight + Article 15 accuracy + Article 22 transparency of automated decision-making when Eligibility uses ML + Article 26 deployer obligations. NIST AI RMF Govern + Map + Measure + Manage. ISO 42001 AI Management System. Per -vendor LLM zero-retention posture verified before any operator content or per-subscriber identifier is sent to LLM endpoint at Catalog draft or Eligibility disambiguation. AI-drafted offer copy routes through sibling #520 borderline routing before publish.

Frequently asked questions

What problem does save-offer library management solve for a multi-brand DTC subscription operator?

A DTC subscription operator running 5-15 brands and 200,000 subscribers maintains hundreds of save-offers across product line + tier + cohort + state-residency + cancellation-reason cluster + LTV-decile + acquisition-channel + loyalty-tier + retention-stage. Every offer carries different eligibility rules, stacking semantics, margin caps, expiration windows, A/B variant assignments, version pins, and per-state disclosure language. When merchandising adds a 30 percent discount, legal needs to validate it against MAP, Robinson-Patman, and per-state pricing disclosure before it ships. When the FTC issues new guidance on Endorsement Guides AI-content disclosure, every offer that uses testimonial language needs re-validation. When an offer expires, it needs to be retired from every channel + every bandit policy + every Q+A surface. Without unified library management, offers stack in conflict, MAP gets breached, comparative-savings claims drift away from substantiation, and the substantiation chain for FTC defense cannot be reconstructed.

What is the 4-skill bundle and what does each skill do?

Catalog maintains the unified offer library across vendor surfaces (Recharge discount rules + Bold offers + Loop + Skio + OrderGroove + Smartrr + Stay AI + Chargebee Coupons + Stripe Coupons + Shopify Discounts + Voucherify + Talon.One + Cordial + Klaviyo Coupons + PostScript Offers + Attentive Offers + Yotpo Loyalty + LoyaltyLion + Smile.io + Antavo). Per-offer canonical record covers offer ID, type, content template, asset CDN URL, metadata, source-vendor pointer, version pointer, effective date, revocation date, claim substantiation pointer, sibling-handoff pointer to #518 save-flow propensity. Eligibility evaluates per-subscriber per-offer applicability via operator-counsel-approved rule registry covering LTV decile, tenure cohort, acquisition channel, vertical, product line, tier, state residency, country residency, loyalty tier, payment method, billing frequency, shipping ZIP, cancellation-reason cluster (sibling #514), prior redemption count. Stack runs operator-counsel-approved stack-conflict resolution across per-product + per-cart + per-subscriber stack caps with vendor-native conflict resolution and explainability trace. Audit ships per-offer canonical record + per-redemption canonical record to WORM storage for FTC substantiation defense + state-AG enforcement + Robinson-Patman defense + class-action discovery.

Why is Robinson-Patman + MAP Colgate doctrine + comparative-claim substantiation the operationally distinctive anchor for this skill?

Save-offer governance is a price-and-claim regime. Robinson-Patman Act 15 USC 13 prohibits price discrimination between competing resellers; the FTC indicated renewed enforcement interest starting 2022. The MAP Colgate doctrine (United States v Colgate 1919) draws the line between unilateral pricing policies (permitted) and resale price maintenance agreements (per se illegal under Sherman Act 1). FTC Section 5 substantiation doctrine (Pfizer 1972 reasonable-basis) governs every offer claim including comparative-savings claims. Pom Wonderful v FTC (2013) and Bayer Aspirin (2015) established discipline on comparative health claims that extends to comparative price claims (claim of save 50 percent must be substantiable). Operationally distinctive frame: an offer library where merchandising adds offers without compliance gating produces a substrate where MAP breaches happen by accident, Robinson-Patman exposure accumulates across cohorts, and comparative-savings substantiation evidence is missing when the FTC letter arrives. The library is the substantiation register; per-offer version pinning is what makes the register useful at audit time.

What real regulatory and standards-body hooks does the compliance overlay anchor on?

Anchor 1 is Robinson-Patman Act 15 USC 13 + MAP Colgate doctrine (United States v Colgate 1919) + FTC Section 5 + substantiation doctrine (Pfizer 1972 reasonable-basis) + comparative-claim discipline (Pom Wonderful v FTC 2013 + Bayer Aspirin 2015) + FTC Mail Order Rule 16 CFR Part 435 + FTC Fake Review Rule 16 CFR Part 465 (Oct 2024) when offer surfaces with social-proof + FTC Endorsement Guides 16 CFR Part 255 + per-state UDAP + per-state pricing-and-discount disclosure (regular price vs sale price disclosure + duration of offer + auto-renewal disclosure at offer time). Anchor 2 is FTC Click-to-Cancel Rule 16 CFR Part 425 + multi-state Automatic Renewal Laws (CA Bus and Prof Code 17600-17606 + NY GBL 527-a + VT Act 110 + CO HB 21-1239 + IL HB 4422 + HI Act 218) + Massachusetts AG v Sirius XM 2017 (pairs with sibling #514 cancellation-reason clustering + #518 save-flow propensity which consume this library). Anchor 3 is per-vertical product-category regulators: Magnuson-Moss Warranty Act 15 USC 2301 when offer affects warranty + state lemon laws + COPPA 15 USC 6501 when minors scope + California Proposition 65 when restricted-substance product + state cannabis Metrc tracking when cannabis SKU + alcohol DISCUS tied-house rules when alcohol SKU + FDA Tobacco Control Act when tobacco SKU + FDA + DSHEA when dietary supplements. Anchor 4 is CCPA + CPRA + state-comprehensive-privacy (17 states enumerated) + GDPR + Washington My Health My Data Act 2024 + DSAR overlay across offer-redemption history + per-customer right-to-be-forgotten propagation. Anchor 5 is EU AI Act Article 50 transparency for AI-generated content when offer copy is AI-drafted + Article 13 + Article 14 human oversight + Article 15 accuracy + Article 22 transparency of automated decision-making when eligibility uses ML + NIST AI RMF + ISO 42001 + per-vendor LLM zero-retention.

How does Stack prevent offers from combining into substantiation breaches?

Stacking is where the substantiation chain breaks. A 20 percent loyalty-tier offer combined with a 15 percent acquisition-channel offer combined with a 10 percent referral offer adds to 45 percent, which may breach MAP, may breach margin floor, may breach Robinson-Patman if the combination applies only to a competing-reseller cohort, and may breach state pricing disclosure if the stack is presented without clear breakdown. Stack runs operator-counsel-approved resolution: per-offer stack-eligibility flag, per-cart stack cap (operator-counsel-set), per-subscriber stack cap, per-vendor conflict resolution (Recharge stack vs Shopify stack vs Loyalty stack), per-loyalty-program conflict, per-referral-program conflict, and per-MAP per-product floor enforcement. Best-of-stack vs additive-stack chosen per operator-counsel policy. Explainability trace per stack decision documents which offers combined, which were suppressed, and why; the trace is the substantiation record for state-AG and FTC review.
