Key Data Elements

The 7 KDEs, satisfied automatically.

21 CFR 1.1455 defines the Key Data Elements required at each Critical Tracking Event. Every KDE below is captured by FarmGuard sensors or Loess-Lattice axis readings and written to a signed receipt at the moment of the event.

KDE 01
Traceability Lot Code
A unique identifier bound to each harvest event. Generated from soil-microbial entropy at the moment of harvest, making the lot code physically unforgeable and geographically anchored.
Loess-Lattice · Axes 17–20 (soil entropy)
TLC: SHA3-256(axis17‖axis18‖harvest_ts)
→ 3f9a2c…d814e7
KDE 02
Growing Area Coordinates
GPS coordinates paired with the soil microbial signature of that precise location. The pairing means coordinates cannot be spoofed without also replicating the unique soil community at that point.
FarmGuard GPS + Loess-Lattice Axis 17
lat: 38.847291, lon: -121.094832
sig: microbial_hash[ax17]
KDE 03
Production Date
Harvest timestamp anchored to an atomic clock reference and cross-validated with a chlorophyll fluorescence reading from the FarmGuard optical sensor, making post-hoc date alteration detectable.
FarmGuard atomic clock + Axis 21 (chlorophyll)
2025-11-03T06:14:22Z
chl_f: 742nm / 0.824 Fv/Fm
KDE 04
Cultivar
Variety identity derived from seed germination spectral signature. Captured at planting by Axis 22 (seed provenance) and carried forward to every downstream receipt in the compliance chain.
Loess-Lattice Axis 22 (seed provenance)
cultivar: "Romaine 'Parris Island'"
axis22_sig: 0xA3F2…C9D1
KDE 05
Receiver Location
Distribution hub identifier captured at the moment of physical receipt scan. The at-receipt scan produces a signed event that records the receiving facility's GS1 GLN and the receipt timestamp.
FarmGuard at-receipt scan + GLN lookup
gln: 0614141123452
recv_ts: 2025-11-04T09:31:00Z
KDE 06
Quantity
Weight and count attestation recorded at pack-out. Both values are co-signed by the Loess-Lattice receipt, creating a tamper-evident weight and unit record that travels with the lot code.
FarmGuard load-cell + Loess pack receipt
weight_kg: 453.2, units: 1200
attest: signed_receipt_v2
KDE 07
Transformation Date
The timestamp of any processing event — cutting, freezing, washing, mixing — that creates a new traceable item. Every transformation produces a cross-axis bundle signature linking the input lot to the output lot.
Loess-Lattice cross-axis bundle · Axes 17–24
xform_ts: 2025-11-04T14:05:10Z
bundle_sig: ML-DSA-65/0xF10C…

KDE definitions per 21 CFR 1.1455. Signed receipts are ML-DSA-65 (NIST FIPS 204). All axis readings written to immutable append-only log.


Critical Tracking Events

All 7 CTEs. Every one attested.

FDA defines Critical Tracking Events as the moments at which traceability data must be captured. The table below maps each CTE to the Loess-Lattice agent that attests it. Reference: 21 CFR 1.1345.

No. CTE Description Attesting Agent
CTE-1 Growing Produce is grown in an outdoor or indoor environment, or harvested from the wild. FarmGuard + Axes 17–21
Soil, GPS, chlorophyll, humidity continuous log
CTE-2 Receiving A person receives a food on the Food Traceability List from another person. FarmGuard at-receipt scan
GLN + timestamp + lot-code cross-reference
CTE-3 Creating A food on the list is created by combining ingredients, one or more of which is on the list. Loess-Lattice bundle receipt
Input lots linked via cross-axis signature
CTE-4 Transforming A food on the list undergoes a change — cutting, freezing, cooking — that creates a new item. Loess-Lattice Axis 24 + bundle sig
KDE 07 transformation timestamp and cross-sig
CTE-5 Shipping A food on the list is shipped to another person. FarmGuard shipment event
Lot code + carrier ID + departure timestamp
CTE-6 Cooling A raw agricultural commodity on the list is first cooled after harvest. FarmGuard thermistor + Axis 20
Continuous cold-chain temperature log
CTE-7 Initial Packing A raw agricultural commodity not obtained from a farm is packed for the first time. FarmGuard pack event + Loess receipt
Weight, count, lot code sealed in signed receipt

Bundle Pricing

4–8x less than legacy FSMA 204 software.

The complete bundle. Hardware, subscription, compliance engine, two-year record retention, and on-demand FDA inspector export — no upsells.

FSMA 204 in a Box — Year 1
FarmGuard hardware (one-time) $1,577
Loess-Lattice subscription × 12 mo $1,188
Auto-compliance engine × 12 mo $3,588
KDE export (CSV / EDI 852) $0
2-year record retention included
FDA inspector signed-URL export included
Year 1 total per facility $6,353

Year 2+ recurring: ($99 + $299) × 12 = $4,776 / yr. Hardware is a one-time cost.

Industry comparison

Comparable FSMA 204 traceability software is typically licensed at $25,000–$80,000 per year per facility, before implementation and training costs.

FSMA 204 in a Box (Year 1) $6,353
Industry low ($25K) $25,000
Industry median (~$50K) $50,000
Industry high ($80K) $80,000

Cost reduction: 3.9× vs. the low end, 7.9× vs. the high end. Year 2+ recurring at $4,776 widens the gap further. Industry figures based on publicly available vendor pricing; actual costs vary by facility size and configuration.


Auto-Compliance Engine

From sensor to FDA-compliant CSV in five steps.

The compliance engine runs continuously on the Hive Civilization edge node co-located with FarmGuard hardware. No operator action is required between events.

01
Ingest Purity Receipt JSON
Every FarmGuard event calls /v1/purity/cert/issue and receives a signed Purity Receipt. The compliance engine subscribes to this webhook and processes each receipt within 500 ms of issuance.
02
Map axis readings to KDE fields
Each Loess-Lattice axis reading is deterministically mapped to the KDE it satisfies: axis 17 (soil-microbial) → Traceability Lot Code seed entropy; axis 21 (chlorophyll fluorescence) → Production Date corroboration; axis 22 (seed provenance) → Cultivar. The mapping table is version-controlled and auditable.
03
Generate FDA-compliant CSV
Output conforms to the column schema defined in 21 CFR 1.1455, including the required header row, lot-code linkage columns, and CTE event-type field. One CSV row per CTE event. Files are SHA-256 checksummed on write.
Ref: 21 CFR 1.1455
04
Maintain 2-year retention
All records are stored in US-region object storage (EU available on request) with a 730-day object-lock policy. Deletion before expiry requires dual-authorization and produces an audit trail. This satisfies the retention requirement at 21 CFR 1.1455(b).
Ref: 21 CFR 1.1455(b) — 2-year retention
05
On-demand FDA inspector export
Operators or FDA inspectors with a delegated access token call /v1/fsma204/export?lot=TLC-xxx to receive a pre-signed download URL valid for 24 hours. The URL covers all KDE records for the specified lot, across all CTEs, as a single ZIP. The full chain is returned in under 60 seconds.

Who It Serves

Any CTE entity on the FDA Food Traceability List.

The FDA Food Traceability List covers high-risk produce categories including leafy greens, herbs, fruits, sprouts, and more. Any entity that grows, packs, ships, transforms, or receives these foods must comply with Subpart S by January 20, 2026.

Produce Growers
Fresh fruit and vegetable farms. CTE-1 (Growing) and CTE-6 (Cooling) coverage from day one of FarmGuard deployment.
Leafy Greens Packers
Romaine, spinach, and mixed-green pack operations. CTE-7 (Initial Packing) signed at pack-out with weight, count, and lot-code attestation.
Frozen-Fruit Processors
IQF and block-freeze operations. CTE-4 (Transforming) receipt links incoming raw lot to outgoing frozen SKU.
Fresh-Cut Distributors
Value-added salad kits, cut vegetables, and fruit trays. Each blend creates a cross-lot bundle receipt satisfying CTE-3 (Creating).
Restaurant Supply
Broadline and specialty distributors supplying foodservice. CTE-2 (Receiving) and CTE-5 (Shipping) covered at each warehouse transfer.
Retail Grocery
Retailers on the FDA Traceability List as receivers. CTE-2 at dock receipt. QR scan to full chain-of-custody for any inspector arriving on the floor.

Compliance Posture

What Hive Civilization provides. What you retain.

Hive Civilization, Inc. is not an FDA-registered facility and is not a food business subject to FSMA 204. FSMA 204 in a Box is a data infrastructure product. We provide the sensors, the entropy substrate, the signed-receipt ledger, and the KDE export tooling. We do not file compliance records with FDA on your behalf, nor do we make representations about your regulatory status.

You are the covered entity. You retain compliance responsibility. The data we generate is the substrate from which your compliance records are built. You or your designated compliance officer must verify that the KDE CSV files we produce satisfy the specific requirements of 21 CFR 1.1455 for your facility type and supply chain configuration.

What this means in practice: We capture and sign the data. We store it for two years. We produce the export on demand. You review the export, confirm it covers every CTE applicable to your operations, and maintain it as your official record. If FDA regulations change, we ship mapping-table updates within 30 days, and you review before deploying.

This disclosure does not constitute legal advice. Consult qualified food-safety counsel for a compliance determination specific to your operations.

FAQ

Common questions.

Does this replace my existing traceability software?
No. FSMA 204 in a Box is designed to complement your existing system, not replace it. The auto-compliance engine exports FDA-compliant CSV and EDI that can be ingested by most traceability platforms. If you already use a platform, we become the data-capture and signing layer beneath it; you continue to manage records in your existing tool.
What happens to chain-of-custody when a product changes hands?
Every transformation, blending, or transfer event that would be a CTE under 21 CFR 1.1345 produces a new signed receipt that references the input lot code and records the output lot code. The chain is unbroken. If a downstream party is not yet on FarmGuard, the receiving-end scan can be performed manually and the receipt is flagged as manually attested.
What if my supplier is not yet on FarmGuard?
Manual KDE entry is supported via the Hive operator dashboard. An operator can enter KDE values by hand for any inbound lot where the upstream supplier has not yet deployed FarmGuard. These records are stored and exported alongside hardware-attested records, but are marked with an attestation_type: manual flag. Manual entries carry no soil signature and should be supplemented with supplier-provided documentation.
What if FDA changes the rule after we deploy?
We monitor FDA rulemaking and commit to shipping KDE mapping-table and CSV-schema updates within 30 days of any final rule change that affects Subpart S. Updates are reviewed by your compliance team before deployment. You control the update schedule for your facility. We do not push breaking changes without operator confirmation.
Where is my data stored? Can I choose the region?
US-region object storage is the default for all records (AWS us-east-1). EU-region storage (AWS eu-west-1) is available on request at no additional charge. Data does not leave the selected region. You may change your region election once per 12-month period. If you self-host under the Enterprise tier, you control the storage backend entirely.
Who owns the data generated by my FarmGuard deployment?
You do. Hive Civilization holds a limited license to process your data for the purpose of generating compliance records, as defined in the subscription agreement. We do not sell, share, or use your facility data for training models or benchmarking competitors. You may request a full data export or deletion at any time, subject to the 2-year retention obligation under 21 CFR 1.1455(b).
Can I self-host the compliance engine?
Yes, under the Enterprise tier. The auto-compliance engine is packaged as a Docker container with a documented API surface. Enterprise customers receive source access under a limited-use license, the ability to run the engine on their own infrastructure, and direct engineering support for integration. Enterprise pricing is negotiated per facility configuration. Contact [email protected] for Enterprise terms.
How does this interact with PTI / USDA NOP?
Complementary. PTI (Produce Traceability Initiative) GS1-128 labels and USDA National Organic Program certification are separate frameworks from FSMA 204. The Hive compliance engine outputs a GLN field compatible with PTI labeling standards, and the Loess-Lattice soil provenance records can serve as supporting documentation for NOP organic system plans. We do not replace PTI label printing or NOP certification; we provide the underlying data substrate that feeds both.
