Designing industrial digital systems for intermittent power and variable connectivity
Each weft is one exhibit's own data, normalised; each warp group is a chapter. The probe reads the exhibit's own value where it crosses. Procedural visualisation, not a measurement.
Operate the evidence first
The weft the probe was reading, lifted out of the cloth: the same exhibit at full size, with the probe as its cursor. Choose a weft, step through it, compare its series.

Derived from the illustrative 500-byte raw event payload in calculation C02 plus explicitly assumed local storage structures: 200 bytes for UUID and sequence B-tree index entries (S31, S32), 150 bytes for the atomic outbox state record (S13) and 50 bytes of amortised page-header and WAL frame metadata (S14), totaling 900 bytes per event before backup staging.
Unit: bytes per committed event. Status: derived. Sources: S13, S14, S31, S32.

Derived from an illustrative 4,000 MB local security and maintenance partition budget using the journal sizing and sealing mechanisms in S22 and S1004 and the staged update manifest architecture in S1002. Allocations subtract 1,000 MB for persistent sealed journals (SystemMaxUse), 1,200 MB for signed update staging, 600 MB for incident forensic snapshots and 400 MB for the filesystem keep-free floor, leaving an 800 MB contingency reserve.
Unit: decimal megabytes (MB). Status: derived. Sources: S22, S1002, S1004.

The factory must keep its record when the grid fails
GFT argues that continuity means retaining a safe operating state and an accountable record through interruption and recovery.
01 / 05The thesis
GFT argues that a factory on an unreliable grid should protect a safe local operating boundary and a durable production record, then prove bounded recovery before making remote analytics essential to production.

02 / 05Part I · Specify the interruption
Industrial digital systems in Cameroon must be designed around the conditions in which production actually runs. Intermittent electricity and variable connectivity can interrupt inspection, erase an inadequately protected record and leave management reading a dashboard whose apparent precision hides missing events. National enterprise statistics establish the importance of the problem, …

03 / 05Part II · Keep the local record alive
… but they cannot determine the battery, retention capacity or recovery policy of a particular factory. GFT argues for a safe local operating boundary and a durable production record before dependence on remote analytics. This paper turns that position into a site survey, service classes, protected digital loads, local network requirements, transaction boundaries, bounded queues and explicit recovery states.
Part II · chapters 04 to 07 · 119 minutes · 17 exhibits
04 / 05Part III · Recover a trustworthy operation
It distinguishes consistent storage from durable commits, protocol delivery from application acceptance, timestamp formatting from clock accuracy, and a restarted process from an authorised return to production. The research combines primary institutional publications, protocol specifications and implementation documentation with clearly labelled illustrative calculations. It develops commissioning experiments and procurement obligations that can expose hidden online dependencies and unexplained record loss.
Part III · chapters 08 to 11 · 102 minutes · 16 exhibits
05 / 05Part IV · Prove and govern continuity
The recommendations connect GFT's Cameroon textile programme to an evidence-gated sequence: measure the site, prove the minimal local record, qualify inspection and synchronisation, rehearse restoration and expand only after the results support it. No site availability, equipment performance or financial return is claimed without operating evidence.
Part IV · chapters 12 to 14 · 80 minutes · 12 exhibits
