Method and source

Illustrative worked case only: dispatch net mass 1,000 kg derives from 1,020 kg gross less 20 kg observed tare; receipt net mass 990 kg derives from 1,008 kg gross less 18 kg observed tare. Difference, receipt minus dispatch, is -10 kg or -1.0 percent of dispatch net mass. These are teaching inputs, not observed loss, measurement uncertainty or accepted tolerance.

Unit: kg net mass (illustrative). Status: illustrative. Sources: S03, S06. Illustrative figures are teaching examples, not measured factory results.

Cotton value needs evidence that survives the factory

GFT argues that provenance becomes useful when custody controls preserve the evidence behind a saleable claim.

  1. 01 / 05The thesis

    African cotton supply chains should define the claim first, preserve its evidence through every custody transfer and transformation, and publish a passport only within the boundary that those records can support.

  2. 02 / 05Part I · Claims must match the chain

    African cotton can move through many hands before it becomes a garment, while the evidence needed to defend its origin can disappear at a single transfer or blending step. GFT argues that traceability should therefore begin with a precise claim and a workable chain of custody. A digital passport should expose the resulting evidence boundary rather …

    … than imply certainty that the factory cannot establish. This paper follows a proposed cotton chain from producer records and ginning through trading, spinning, fabric processing, garment production and dispatch. It distinguishes physical provenance from certified-content allocation, customs origin and sustainability performance. It specifies practical controls for identifiers, input-output genealogy, volume reconciliation, subcontracting, evidence review, correction and claim release.

    Part II · chapters 04 to 07 · 101 minutes · 16 exhibits

  4. 04 / 05Part III · Passports must preserve evidence

    Standards and institutional guidance inform these controls, while hypothetical examples remain visibly illustrative. The analysis separates future textile passport requirements from current design choices and treats cryptographic credentials as tools for preserving assertions. It addresses constrained connectivity, supplier inclusion, privacy, service continuity and the recurring work required to maintain reliable records.

  5. 05 / 05Part IV · Scale follows demonstrated control

    A bounded pilot then tests normal transactions, missing evidence, duplicate allocations, copied labels and recovery failures. The closing roadmap defines what GFT would measure before recommending scale. The result is a research and writing specification for an evidence-led white paper, not proof of an operating deployment, certification or regulatory conformity.

Interlude · findings against chapters

10 findings, each argued across the paper.

Finding 01 of 10

A custody framework alone cannot verify the production characteristics asserted by a product claim.S01S02

Finding 02 of 10

Mass-balance allocation and physical cotton provenance need distinct registers and distinct consumer statements.S02S06S07S08

Finding 03 of 10

Certified-material tracking requires documentation through receiving, processing and transfer, supported by volume reconciliation.S03S05S06

Finding 04 of 10

A chain's possible origins become broader when inputs are blended, so a downstream record must retain its input set and limitations.S01S02S10

Finding 05 of 10

Event semantics and stable identifiers can support inter-company exchange without assuming item-level RFID tracking.S10S11S12

Finding 06 of 10

The Commission describes textile-specific passport fields as future delegated-act requirements, so an indicative adoption date is not a compliance deadline.S14S15

Finding 07 of 10

A valid digital credential preserves an issuer's assertion; accepting its physical claim also requires a trust policy and admissible evidence.S21S23S24S29

Finding 08 of 10

Isotope analysis offers a corroboration route, but no Cameroon-specific classification accuracy is established by the source opened here.S33

Finding 09 of 10

Traceability must limit personal-data collection and keep supplier mapping separate from labour due diligence and remediation.S17S19S20

Finding 10 of 10

GFT should expand only after an independently reviewed pilot demonstrates supported claims, reproducible quantities and recovery from adverse cases.S03S06S10S27

Cell strength is the recurrence of each finding's key terms in each chapter's text, computed from this web edition and scaled to the strongest chapter. It is a reading guide, not a citation.

Evidence stays attached

Source quality is part of the argument.

Every knot on the edge is one of the 225 records the chapters cite, sorted by grade. The counters filter them; select a record to read it and to light the chapters that cite it. A grade describes the supplied evidence record, not independent validation by the website; missing references are excluded.
