The first P3 (a84abf3) ran on the wrong model and its palette never reached the TUI: MESH_THEME_16 was written in 256-colour cube indices instead of the 16 VT slots, and the platform theme pick was wired into the scripted-CLI console while the real rasterizer stayed hardcoded to truecolor. Replace it end to end: - theme._VT_SLOTS: the canonical slot->RGB design (conventional hue families kept; slots 5/6 become the track/faint slates), MESH_THEME_16 rewritten against color(0..15) with the VT's bold-as-brightness and dim-bank-background rules pinned by tests. /etc/vtrgb + a boot oneshot install it (console-font script), OSC fallback when kbd is absent. - platforms.on_platform: set_platform now re-runs registered bindings, so theme, rasterizer and widgets swap implementations once per switch and hot paths read module globals - no per-call get_platform(). - The render-boundary fold (theme.fold_text): one str.translate pass (NFKD accent folds - the Terminus base has no accented Latin - plus symbol stand-ins and the width-padded emoji map), an embedded-SGR quantizer for canvas truecolor, and a ?-at-own-width catch-all that makes the no-wide-glyph short-circuit true by construction. Applied at the only two places every visible byte passes: render_to_ansi and MapCanvas.to_ansi_lines. - ui/fontset.py freezes the installed font's inventory (dumped live); the gallery now asserts rendered picocalc ANSI carries no truecolor/ 256-colour SGR and no character outside it - the parity gate the first attempt faked by asserting a dataclass field. - Font build: nine new 6x12 marks (ellipsis, warn, backspace, shift, gear, refresh, clock, crosshair, padlock) drawn into donor slots, with donor misses now fatal and a keeper canary (donating pi once erased Cyrillic pe - shared slot). Table re-dumped on-device: identical to fontset.py, 519 = 519. - Type-based name colouring: registry moved to core/nodetypes (services no longer import ui), fed from monitor observations, heard_nodes and merge_contacts. Heat gradient quantizes to heat.* steps on picocalc. - ui/marks.py: the P2-deferred constant relocation - widgets no longer drags map_render/mapcanvas/pathgraph for tuples and aliases. - meshterm specimen: the visual language on one card through the real funnels - the on-device acceptance screen (JP's request). - tools/chat: delivered/no-ack state uses the standard check/query marks, not the banned emoji pair. Verified on the Lyra: font+palette installed, specimen framebuffer captures in .claude/plans/. 1259 tests green, 13 xfailed (P6 list). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

"""The PicoCalc console font's codepoint inventory — the glyph contract.
|
||
|
||
The PicoCalc panel draws through the kernel console with one 512-glyph PSF font
|
||
(``meshterm.psf.gz``, built by ``scripts/calculinux-console-font.sh``): the stock
|
||
Terminus 6×12 base (a Cyrillic-coverage table — note there are **no accented Latin
|
||
letters**), the full braille block, MeshTerm's own marks drawn into donor slots, and a
|
||
few aliases. A character outside this set renders as a blank on the panel, so *nothing
|
||
outside it may ever be emitted* on the picocalc platform — the render boundary folds
|
||
text down to it (:func:`meshterm.ui.theme.fold_text`), and the dual-platform gallery
|
||
asserts the fold held.
|
||
|
||
This table is the **single source of truth** for that contract, shared by the runtime
|
||
fold and the tests. It mirrors the font actually installed on the device: the base
|
||
inventory was dumped live from the PSF's Unicode table (2026-08-01), minus the donor
|
||
codepoints the build script now repurposes, plus the marks it draws in their place.
|
||
If the build script's ``MARKS``/``DONORS``/``ALIASES`` change, this table must move in
|
||
the same commit — and vice versa.
