A digital product passport fails on the factory floor long before it fails in a browser if the people who weigh bales, join fabric rolls, approve rework and inspect incoming certificates lack authority or time to record what happened.[S03] Traceability governance works only when every material observation has an accountable role, capture occurs at the point of work, outages place claims into a visible pending state, personal data collection stays restricted to a lawful purpose, and workers or producers have safe routes to challenge errors and report harm.[S10][S19][S1101] Green Future Tech Limited (GFT), Hong Kong SAR, specifies this operating discipline as a proposed extension to its three-part Cameroon textile programme, prepared on 31 January 2024 with source refreshes retained in 2026 (feasibility study, performance-management system design and digital strategy).[R06] None of the roles, exception workflows, privacy registers or training drills here is presented as a running factory deployment or audited compliance result; each is an engineering design to test in a bounded pilot before releasing any commercial origin claim.[S01][S02]

Read this exhibit in its chapter ↗Chain-of-custody standards require documented responsibilities across receiving, storage, processing, subcontracting, volume reconciliation and claim release.[S03][S06] Many traceability projects configure software as if one administrator enters and approves every transaction. On a real spinning, weaving, dyeing or garment floor, custody moves across teams whose incentives diverge when a delivery arrives without paperwork, a roll split loses its ticket or a shipment faces a dispatch deadline.[S06][S10] If the person measured on shift throughput also holds unrestricted authority to override a missing input link or release a product claim, records will bend toward shipping targets rather than evidential accuracy.[S02][S03]
To prevent unverified material from entering an eligible pool by default, GFT separates operational observation from exception resolution and claim release.[S03][S06] Under the Content Claim Standard (CCS) published by Textile Exchange and Version 1.0 of the Aid by Trade Foundation (AbTF) Transparency Standard dated June 2025, a site must verify transport and transaction documents at receipt, maintain physical or temporal separation where required, reconcile volumes, and prevent double claiming.[S03][S06] Translating those rules into daily work requires six functional roles, even where a smaller facility combines several operational duties under shared supervision during early ramp-up.[S06][S17]
Where pilot staffing does not allow six individuals on every shift, GFT sets a minimum two-person rule for high-risk custody decisions: the person recording a receipt or transformation cannot approve an exception override, execute an irreversible downgrade under Section 7.2 of the June 2025 AbTF standard, or authorise claim release.[S06] Role assignments follow zero-trust access principles: subject and device authentication are checked before any session writes or approves a custody event, regardless of network location.[S26]
Exhibit 46 places these illustrative custody tasks across two dimensions: operational frequency during shift work and the independence of review required before supporting an external claim.[S03][S06][S17]
As Exhibit 46 shows, high-frequency events such as batch transformation logging and receipt checks sit in the lower-right region where standardised operator capture and format validation keep work moving.[S03][S10] Actions that alter claim admissibility, including subcontractor dispatch approvals, volume reconciliation sign-offs, irreversible downgrades from Hard Identity Preserved (HIP) or Segregation to mass balance, and final passport release, sit in the upper quadrants where independent review or dual control is mandatory.[S06] This chart is a governance design rather than a measured scorecard; it cannot establish that a facility has enough staff for each gate without pilot verification.[S03]
A traceability system fails when exceptions wait for a quarterly audit, because physical lots have already been blended, cut, sewn and shipped before a discrepancy is noticed.[S03][S10] In GFT's Cameroon textile programme, the performance-management design sets a tiered review rhythm across shift handovers, daily production reviews, weekly plant reconciliations and monthly governance (covered in wp02 and the kpi-cascade tool).[R06] GFT proposes embedding custody exception review into that cadence rather than creating parallel meetings.[S03][S06]
At shift handover, the line leader and receiving officer review unclosed batches, quarantined receipts and damaged bale labels from the shift.[S06][S10] At the daily operational meeting, the quality reviewer and purchasing coordinator inspect shipments or cutting lays held for missing counterparty confirmation or subcontractor scope, assigning an owner to obtain the document or downgrade the batch claim.[S06][S09] At the weekly plant review, the data steward and claim-release officer reconcile physical stock against the eligible claims ledger before approving outbound passport disclosures.[S03][S06] Connecting traceability to the management cadence is a proposed extension; GFT has not operated this cadence in a live Cameroon mill.[R06]

Retrospective reconstruction, where clerks type Monday's paper tally sheets into a spreadsheet on Friday afternoon, introduces transcription errors, loses the sequence of roll splits and encourages silent averaging of waste.[S03][S10] Consistent with the data-first discipline of GFT's Cameroon textile programme, custody evidence should be captured at the physical boundary where material changes hands or form, using compact forms with pre-validated identifiers.[R06][S10]
A common error in factory digitalisation is assuming that an enterprise resource planning (ERP) purchase order or invoice suffices as a custody record.[S09][S10] Commercial documents record financial obligations and pricing tiers, which often aggregate deliveries, omit bale or roll identifiers, or pass title through a trader who never takes physical possession.[S01][S10] The Sustainable Cotton Tracker (SCOT) operated for Cotton made in Africa shows why custody tracking and commercial ordering remain distinct: the SCOT FAQ states that the platform is not an order system, and instead requires registered counterparties to record and confirm certified material transactions by supply-chain role.[S09]
unknown-input exception and print a quarantine ticket, rather than inventing a code to pass a mandatory field.[S01][S10]Barcode scans, scale confirmations, roll-split tickets and exception holds take physical time on the floor.[S03][S06] If engineers assume operators absorb extra capture steps at zero cost, workers under throughput pressure will batch scans at shift end, bypassing validation.[S10] In Cameroon, where WageIndicator records a standard 40-hour week, a 48-hour legal maximum with overtime at 1.2 times base pay, and a statutory monthly minimum wage (SMIG) raised to XAF 43,969 from 23 February 2024 (about US$76, up 5 percent from XAF 41,875 in 2023), administrative tasks must be budgeted within lawful shift hours.[R14][R16]

The lesson of Exhibit 47 is structural: even under point-of-work capture, the 8 illustrative exception events require 63.0 minutes (27.0 + 36.0), exceeding the 41.4 minutes spent on all 92 routine scans.[S03][S10] Under retrospective reconstruction, chasing those 8 exceptions after physical lots have moved consumes 176.0 minutes and often ends in a batch downgrade.[S10] Because these durations are illustrative assumptions, GFT requires the Chapter 13 pilot to time live scan, relabelling and hold durations before fixing staffing ratios or unit-cost denominators in Chapter 12.[S03]

Industrial zones and rural ginning corridors in Central and West Africa face intermittent telecommunications and grid power interruptions (whose electrical and edge-computing engineering is addressed in wp07 and edge-architecture).[S10][S27] When a cloud-only portal drops offline while trucks unload seed cotton or a dye house batches fabric rolls, operators must halt production, skip the digital record, or scribble notes on paper for later entry.[S10] A governance model assuming continuous connectivity will stall the factory or corrupt custody during its first outage.[S10][S27]
GFT specifies an offline-first custody capture discipline to test during the pilot.[S10][S27] Every receiving dock, ginning press, spinning group, dye kitchen and cutting terminal operates against a local edge queue on non-volatile storage with battery backup.[S26][S27] Before a shift starts, the local node caches the supplier scope register, active production order identifiers and a block of pre-issued batch and event identifiers.[S10][S26]
When connectivity drops, operators continue scanning bales, logging transformations and printing local batch tickets from the pre-issued pool.[S10] Each observation is signed by the authenticated local device and operator session and appended to an append-only local log.[S23][S26] While disconnected from the central ledger, the local system enforces a strict boundary: it confirms internal observations and moves work-in-progress between workstations, but cannot verify external counterparty status lists, confirm an inbound electronic transaction certificate, or release an outbound passport claim.[S06][S24]
When connectivity returns and queued records upload, naive databases overwrite the physical operation timestamp with server ingestion time.[S10] If a spinning laydown occurred at 09:15 on Tuesday during an outage, and the yarn shipment was logged from a connected dispatch office at 14:00 before the spinning terminal reconnected at 16:30, server receipt time makes the yarn appear shipped two hours before it was spun.[S10] Automated genealogy checks then reject the shipment or attach it to an unrelated lot.[S10]
GS1 EPCIS Release 2.0 resolves this by separating eventTime (when the physical event occurred, with local time-zone offset) from recordTime (when the event was recorded by the repository).[S10] Combined with GS1 Core Business Vocabulary (CBV) Release 2.0 dispositions and business steps, preserving both timestamps lets the central ledger reconstruct the physical sequence after delayed upload while flagging clock-drift anomalies for steward review.[S10][S11]
To keep offline capture auditable without inventing certainty during a link failure, GFT specifies a five-step protocol grounded in GS1 EPCIS Release 2.0 semantics and NIST SP 800-161 Rev. 1 resilience controls:[S10][S27]

As Exhibit 48 shows, a power or network outage never forces an operator to choose between halting a spinning frame and fabricating a timestamp.[S10] Production continues against local identifiers, while external claim release pauses until eventTime ordering, volume balances and certificate status checks are reconciled.[S06][S10][S24] What Exhibit 48 cannot guarantee is hardware survival during prolonged power loss without the backup power and surge protection specified in wp07.[S27]

Traceability programmes often over-collect personal information under the false belief that publishing a farmer's name, national identity number, household GPS polygon or a sewing operator's payroll record makes a product passport more credible.[S19][S28] Indiscriminate collection exposes smallholders and workers to privacy breaches and commercial poaching while creating legal liabilities for every entity storing or transferring the data.[S19][S1102]
The European Data Protection Board (EDPB) guide for small businesses states the rule of data minimisation: an organisation can process only personal data that are necessary and proportionate for the specific purpose envisaged.[S19] When a brand or buyer verifies whether cotton shirts meet an origin or certified-content claim, it needs admissible evidence of custody, ginning campaign linkage, certification scope and volume reconciliation.[S03][S06][S28] Neither a consumer scanning a QR code nor a sourcing team inspecting a shipment pack needs the personal names, phone numbers, biometrics or home coordinates of farmers or sewing workers.[S19][S28]
In northern Cameroon, where inherited evidence record R03 notes that SODECOTON supports more than 220,000 cotton producers across nine ginning plants and two oil mills, production involves hundreds of thousands of households in producer groups.[R03] Recording deliveries at the ginnery requires a link to a producer group or pseudonymous member code so payment, agronomy support and scheme eligibility can be audited by certification bodies.[S06][S19] Publishing those personal records in a downstream feed or public passport violates purpose limitation and creates an irreversible privacy exposure.[S19][S28]
Traceability systems spanning Cameroon production, Hong Kong SAR engineering and global export markets cross multiple legal regimes.[S19][S1102] Under the EU General Data Protection Regulation (GDPR), territorial scope is conditional on establishment or targeting/monitoring in the Union.[S19] Simultaneously, domestic African laws govern processing at the source.[S1102] In Cameroon, practitioner commentary published by LEX Africa on 31 October 2025 highlights Law No. 2024/017 of 23 December 2024 on personal data protection, covering collection, recording, storage, retrieval, transmission, alignment, erasure or transfer of personal data, and requiring consent, compliance protocols and prior authorisation from the Data Protection Authority where applicable (noting an alignment window to 23 June 2026).[S1102]
Because GFT does not provide legal advice and statutes require review by local counsel (see wp17), GFT designs the data model around data minimisation and segregated storage.[S19][S1102] Personal identifiers of producers and workers stay in restricted local cooperative or HR registries in Cameroon; the custody ledger and product passport receive only pseudonymous group, shift or workstation codes, role titles and institutional certificate references.[S19][S26][S28]
Exhibit 49 sets out GFT's illustrative privacy-by-purpose register across five data categories in a cotton-to-garment chain.[S19][S28][S1102]

The rule in Exhibit 49 is that the custody ledger never acts as a personnel file.[S19][S28] When a buyer or auditor inspects a garment batch, they see that receiving check RCV-2026-0412 was logged by Role: Receiving-Dock-A and released by Role: QA-Reviewer-02 under an active scope certificate.[S03][S26] If an accredited auditor on site needs to verify that QA-Reviewer-02 completed required AbTF training, the plant's internal register resolves that token locally without exporting employee files into cloud passports.[S06][S19][S1102]

Read this exhibit in its chapter ↗A digital map of supplier tiers and bale lot numbers is an input to supply-chain management, not proof that people growing cotton or sewing garments work under fair, safe and voluntary conditions.[S17][S20] Conflating traceability with labour assurance creates two hazards: buyers may treat an EPCIS event graph as a substitute for workplace due diligence, or designers may attach unverified labour-risk scores to supplier nodes without giving workers or producers a safe route to contest errors or obtain remedy.[S17][S20][S1101]
The International Labour Organization (ILO) defines forced labour as work or service exacted from any person under the threat of a penalty and for which the person has not offered themselves voluntarily, covering all work in any activity, industry or sector, including the informal economy.[S20] In Cameroon, where inherited record R16 notes an informal employment share of about 90 percent, labour due diligence requires ongoing attention to recruitment, wages, working hours, overtime consent and subcontracting.[R16][S20] A barcode scan confirming that a bale moved to a spinning mill, or that panels were sewn on Line 3, records where material moved and when; it provides zero observation of whether wages were paid, overtime was voluntary, or freedom of association was respected.[S10][S20]
Similarly, the OECD Due Diligence Guidance for Responsible Supply Chains in the Garment and Footwear Sector emphasises practical, collaborative approaches to identifying, preventing, mitigating and accounting for how enterprises address adverse impacts.[S17] Traceability records identify which facilities, subcontractors and ginning corridors participate in a chain so risk assessments can be targeted.[S17] Once mapped, due diligence requires workplace assessment, corrective action plans, purchasing practices that do not induce unauthorised subcontracting or excessive overtime, and verified remediation.[S17][S1101]
Under Principle 29 of the United Nations Guiding Principles on Business and Human Rights (UNGPs) published by the Office of the United Nations High Commissioner for Human Rights (OHCHR), enterprises should establish or join operational-level grievance mechanisms for adversely impacted individuals and communities so grievances are addressed early and remediated directly.[S1101] Principle 29 and Principle 31 explain that these channels support due diligence by surfacing concerns before harms compound, and must meet effectiveness criteria (legitimacy, accessibility, predictability, equitability, transparency, rights-compatibility, learning and dialogue) without undermining trade unions or judicial recourse.[S1101]
In an operable governance system, GFT separates three complaint pathways so each reaches a competent owner with confidentiality safeguards.[S03][S17][S1101]
Where a grievance reveals an operational cause threatening custody integrity, such as late order changes forcing unrecorded night-shift subcontracting, the committee issues an anonymised corrective requirement to purchasing and operations without exposing the complainant.[S06][S17][S1101]

Chain-of-custody standards require organisations to train staff on traceability procedures and retain training records.[S06] Most implementation budgets spend training hours on the "happy path" in a classroom: scanning a clean barcode on an intact bale with fast Wi-Fi and a matching delivery note.[S06][S10] Within forty-eight hours of launch, an operator faces a rain-smudged tag, a split roll lacking a child ticket, a subcontractor return with a 15 kg weight difference, or a disconnected terminal.[S06][S10] Without exception rehearsals, operators improvise workarounds that corrupt the genealogy graph.[S03][S10]

As Exhibit 50 shows, the "happy path" scan in the lower-left quadrant carries low recovery complexity and low defect risk because software validates it automatically.[S10] High-severity cases in the upper quadrants, including unknown rolls in a cutting lay, duplicate bale codes, expired scope certificates and offline queue sync, require practiced judgment across operator, quality and steward roles.[S06][S10] Exhibit 50 sets the curriculum for pilot readiness; it does not claim any Cameroon workforce has yet been tested against these scenarios, and pass rates must be recorded during the Chapter 13 pilot.[S06]
Delivering an operable governance system yields three artefacts for the rest of this paper: the six-role responsibility matrix (Exhibit 46), the offline and exception standard-work protocols (Exhibit 48 and Exhibit 50), and the privacy-by-purpose register (Exhibit 49).[S03][S10][S19] Every control requires operator minutes, labels, edge storage, drills and independent review.[S06] Chapter 12 prices that recurring work against bounded counterfactual benefits before any platform vendor is chosen.[S03][S27]

01Part I: Claims must match the chain
GFT argues that provenance becomes useful when custody controls preserve the evidence behind a saleable claim.
02Part I: Claims must match the chain
Select the custody model by the attribute that must survive, then design operations to maintain that attribute.
03Part I: Claims must match the chain
An origin claim needs a defined producer boundary and a documented link from receipts to ginned fibre.
04Part II: Every transformation needs a record
A shipment is traceable only when dispatch and receipt refer to the same material and discrepancies remain visible.
05Part II: Every transformation needs a record
Each production step must preserve enough input-output linkage to support the claim carried by its outputs.
06Part II: Every transformation needs a record
Physical stock, processing yield and eligible claims need related but separate accounts.
07Part II: Every transformation needs a record
Assurance is credible when its issuer, scope, validity and sampling limitations remain attached to the claim.
08Part III: Passports must preserve evidence
Interoperability requires common semantics, stable identifiers and a tested way to exchange corrections.
09Part III: Passports must preserve evidence
A useful passport identifies its product, states who makes each claim and reveals the limits of the supporting evidence. Proposed fields must remain distinct from future legal requirements.
10Part III: Passports must preserve evidence
Cryptography can preserve an assertion and identify its signing authority, but accepting a textile claim still requires physical evidence and an explicit trust policy.
11Part III: Passports must preserve evidence
A system survives only if responsibilities, exceptions, privacy and constrained connectivity are part of ordinary work.
12Part IV: Scale follows demonstrated control
Compare the cost of producing admissible evidence with bounded benefits rather than an assumed premium.
13Part IV: Scale follows demonstrated control
Pilot success requires adverse cases, reproducible evidence and independently reviewed release decisions.
14Part IV: Scale follows demonstrated control
GFT recommends a staged programme in which every expansion follows demonstrated control of evidence, quantities and disclosure.
