Tai looked at it. He nodded slowly. He took a sip.

Tai’s mission was singular: create a single, unambiguous, unstretchable, universally readable font for every drawing, every detail, every bubble note. For six months, Tai disappeared into the AutoCAD command line. Colleagues saw him only by the glow of his CRT monitor, typing furiously:

Anya realized: Tai had built a slow-motion self-destruct. He believed that no drawing should live forever. After 10 years or 5,000 revisions—whichever came first—the font would begin to scramble itself. The �0’ becoming �O’ was the first symptom. The black squares were stage two. Stage three, she calculated, would arrive in 2015: every letter would invert into its ASCII complement (A→Z, B→Y, space→tilde).

Tai became a ghost. He refused to share the source code of TAI_FULL.SHX . He simply handed out the compiled font file. When IT asked for the shape definition (the .SHP file), Tai smiled. “Not needed. Just use the font.”

The letter �A’ in TAI_FULL had 47 control points. Tai had programmed it so that the 12th point shifted by 0.0001 drawing units each time the file was saved. Over hundreds of saves, the �A’ would subtly lean. A thousand saves? It would begin to resemble an �@’ symbol.

In a final, desperate act, Anya flew to Isaan. She found Tai in a bamboo hut, sipping nam oi (sugarcane juice). She showed him a printout of a corrupted detail: ⌀25mm @ 150 O.C. now read ♦25mm ♥ 15O �.C.
