Case study · June 2026 · Codex Reg v1.0

One review cycle.
One $40K-saving finding.

An ancient-grain snack brand preparing for a 10-state Year-1 launch. Codex Reg ran all three workflows. The top finding was a 21 CFR §101.91 gluten-free / barley conflict that sat undetected in the brand's own strategic plan.

The brand (de-identified)

"Brand X" is a US-market ancient-grain puffed snack brand in launch mode. Founder-led, <$10M revenue, two SKU concepts in active development (a 3-ingredient base SKU and a 6-ingredient seasoned variant). The brand carries gluten-free claims, "high-protein" language, and "regenerative agriculture" positioning, and plans a specialty-retail-led launch with national ambitions inside Year 1.

Why this brand was the right test case. Mid-market, founder-led, document-rich, regulated, time-constrained. Exactly the customer F&B Codex is built for. The brand had a brand brief, a strategic plan, a co-packer spec sheet, and a live waitlist site — the documents were detailed enough to actually review, and the gaps between them were the story.

What Codex Reg ran

All three v1 workflows:

The single biggest finding

The brand's strategic plan and brand brief describe the seasoned SKU as containing sattu, identified in the source documents as "roasted chickpea + barley flour." The same SKU carries a front-of-pack "gluten-free" claim. Under 21 CFR §101.91(a), barley is a gluten-containing grain. A food cannot bear a "gluten-free" claim if it contains an unprocessed gluten-containing grain, with narrow exceptions that require process documentation and finished-product testing <20 ppm.

Why this finding is worth its own line. If this brand had sent its strategic plan to a retailer buyer with the gluten-free claim attached to the sattu SKU, it would have been caught at retailer onboarding — at best by the buyer's quality team, at worst by FDA inspection after shelf. Codex Reg surfaced it before the next investor send. Cost to fix now: reformulate sattu or drop the claim. Cost to fix on shelf: recall + repack + relisting fees that comfortably clear $40K for a small launch.

Other findings worth the cycle

Workflow A — label compliance

Workflow B — claims substantiation

Workflow C — multi-state shipping

The artifact

Brand X received four deliverables, each ending with a signed audit footer JSON:

Plus three signed audit-log JSON files for the brand's compliance binder.

Outcome

Brand X is now refreshing its brand brief and strategic plan with the gluten-free language corrected, has added per-batch gluten testing and a per-lot lead-spec to its co-packer agreement, and has dropped the "high-protein" claim from its retailer sell-sheet pending reformulation. Time elapsed from input upload to deliverable: under 4 hours of agent time. Founder turnaround: same day.

This is the artifact a paying Codex Reg customer receives every time. Same structure. Same audit footer. Same human-checkpoint discipline. The brand chose to remain anonymous in this case study; future case studies will name brands that elect to be named.
