TAFS

TAFS is one of the hidden systems the Civilisation Comparison names for the 29th century UCSD, and the record uses only the initials. No page in it spells them out, and the Archive does not guess at what they stand for.

What the comparison says of it is that it filters. Its comparative table credits it, beside the Reclaimers, for the era's waste being instantly reclaimed, and credits it again for the era's medicine, which the table calls passive, a matter of system-level filtering where the 21st century CE's medicine was advanced but intervention-based. Where the 21st century lived beside waste it could not easily erase, TAFS filtering and Reclaimer pass-throughs remove degraded material before it can become civic memory.

It works to thresholds. Authority to modify a TAFS threshold is among the encoded system permissions a 29th-century guild holds, beside authority to adjust a Coherence Index parameter or issue a Reclaimer directive, and TAFS thresholds are one of the four routes by which control of matter passes through system parameters, with Coherence Index definitions, Reclaimer directives and Ashwarden interventions.

What TAFS filters for, by what means, where its thresholds sit, and who set the first of them, the record has not established.
