PRISM v2.12.3 released

[Ronkupper]

PRISM v2.12.3 is out — a PATCH over v2.12.2 converting the §2.2 visual map to pure ASCII.

Release: https://github.com/Ronkupper/PRISM/releases/tag/v2.12.3

v2.12.2 aligned the map to exact character counts, but mobile testing showed it still drawing crooked: Unicode box-drawing and arrow glyphs are missing from many mobile monospace fonts and substitute from wider fallback faces, so equal character counts don't mean equal rendered width. The map now uses printable ASCII only (+, -, |, v, ->) — uniform advance in every font — with geometry and content unchanged and the block machine-verified (ASCII-only, uniform width, all rails column-true).

Rendering only — no Standing Principle, Monitor, Probe, Gate, or section semantics changed; embedded Lens Library stays v0.13; lint catalog stays v4. Skill archive regenerated via the deterministic projection.

The map still pans horizontally on phones at 72 columns; a narrower phone-width rebuild remains under consideration. Field reports on rendering across devices and vendors welcome in Ideas.
