Objective AI Best Leaf % Grading & Tamper-Proof Intake Audits.
Tea B60 connects factory receiving sheds with national regulatory oversight. Field teams capture green leaf samples, compute instant AI B60 fine-leaf scores, and print QR-verifiable supplier slips—backed by an append-only audit ledger across six role levels.
Field Users (L1), Factory Managers (L2), and Multi-Factory Owners (L3) capture intakes, approve reason-coded corrections, and settle supplier payouts.
Area Inspectors (L4), Regional Additional Commissioners (L5), and the National Commissioner (L6) audit immutable records, log findings, and rule on appeals.
- National Standard
- ≥ 60.0% Two Leaves & Bud Target
- Audit Immutability
- 100% Locked Append-Only Corrections
- Dual-Chain Scope
- L1 → L6 Factory + SLTB Linked
Inspect AI leaf segmentation, L1→L2 override audit, and 80mm thermal slip
Original AI B60 score is locked in Entry v1. L1 can propose a correction but cannot overwrite v1.
From Factory Intake Shed to National Tea Board Oversight
Every green leaf intake follows a deterministic four-stage workflow that protects smallholder suppliers, factory managers, and Sri Lanka Tea Board inspectors alike.
Sample Capture & Weighing
L1 Field User selects the supplier route, records gross weight & moisture deduction, and snaps an overhead leaf tray photo on the mobile PWA.
Instant B60 Leaf Grading
Computer vision segments Two Leaves & Bud vs. coarse leaf and stems, calculates the Best Leaf % against the active SLTB standard, and computes payout.
L2 Approval & Thermal Slip
L1 confirms the AI result or submits a reason-coded correction for L2 Manager sign-off. A tamper-proof QR receipt prints immediately for the supplier.
Regulatory Spot-Checks & Appeals
Tea Board Inspectors (L4), Regional Commissioners (L5), and the National Commissioner (L6) audit locked records, log findings, and adjudicate appeals.
Six Role Levels. Two Independent Chains. One Shared Truth.
Every factory is linked to one Owner (Level 3) and one Inspector Area (Level 4). Select any level below to inspect its exact scope, permissions, and governance boundary.
Field User (Photo Taker)
Operates at the factory receiving shed. Captures green leaf tray photos, records gross weight & moisture deductions, reviews AI Best Leaf % result, and prints thermal supplier receipts.
Primary Responsibilities
- Capture overhead sample photo via mobile/tablet PWA
- Confirm AI B60 % or submit reason-coded correction for L2 sign-off
- Print 80mm QR-verifiable thermal slip for leaf supplier
Enforcement Matrix (Level 1 Capabilities)
Built for Regulatory Trust & Factory-Floor Speed
Designed around strict data immutability, transparent supplier payouts, and pluggable computer-vision grading.
Append-Only Audit Trail (Zero Destructive Edits)
Neither a Field User (L1), a Factory Owner (L3), nor the National Commissioner (L6) can alter or delete a saved intake record. When an L1 user challenges an AI score, the system writes a linked correction proposal that remains inactive until approved by the L2 Factory Manager—preserving both the raw AI inference and the human override for L4–L6 Tea Board inspectors.
Three-Tier Appeal Escalation
Structured dispute resolution protects both smallholders and factories:
- 1. First-Level Supplier DisputeL2 Factory Manager
- 2. Regional Regulatory EscalationL5 Addl. Commissioner
- 3. Binding National DeterminationL6 Commissioner
National B60 Standard Versioning (Level 6)
The Sri Lanka Tea Board Commissioner (L6) configures national B60 target percentages, regional tolerance bands, and grade rate modifiers. Every intake record snapshots the exact b60_standard_version active at the moment of weighing.
Cross-Chain Owner Visibility (Level 3)
Factory Owners (L3) benchmark B60 quality and supplier payouts across all their estates while maintaining direct read-only visibility into Tea Board Inspector findings (L4–L6) raised on their factories—bridging commercial management and regulatory compliance.
