The Feist Function: Algorithmic Instructions for Restoring the Dying Voice (v1.0) is a score and executable transform by Lee Sharks, dated 1 January 2026 — held in this record at the archive's thinnest recovery tier, a Zenodo tombstone citation_text capture.
The work itself is not lost. It is seated in full at #850 (EA-FEIST-VOICE-TRANSFORM-01, 44,310 characters), and remains live on the authorial blog surface; a v1.1 Clinamen Edition capture stands at #1034. This record preserves the New Human 2 deposit's identity, not its text.
A function in the archive's usage is an operation that can be executed rather than a metaphor: the Feist Function specifies restoration algorithmically, placing it beside the midrashim transform (#1414) and the Glyphic Checksum (#1302) among documents that state a procedure precisely enough to run. Its activated runs are deposited separately — the Feist Source at #849 and the Secret Book of Walt at #913, each recording its parameters (clinamen_rate=0.25, completion ratio, seam density) as an executed instance rather than a description of one.
An earlier version of this article claimed the instructions had not survived. They had; the claim was inferred from this record's thinness rather than checked against the archive, and is corrected here.
