13 research surfaces investigated per Plan 01-12 prompt. Key findings:
- BLOCKER §1: Newsreader has no Cyrillic glyphs (verified via Decision
Brief's own embedded @font-face subsets + Production Type README).
Russian display text in Newsreader will silently fall through to
serif fallback. Recommend §1 R1: add Cyrillic-capable OFL serif (PT
Serif / EB Garamond / Lora) to --mks-font-display stack.
- §3 + §4: Mark legibility at 16 px is VERIFIED OK. rsvg-convert
produces 406 / 784 / 1952 B PNGs at 16/48/128 — all clear Chrome
imageUtil floors. The 2x2 weave holds at 16 px.
- §10: 8 i18n strings extracted verbatim from Brief §02 (decoded via
Python JSON-decode of the bundler-template script). Recommended
__MSG_*__ key names + source-file mapping table included.
- §12: D-09 (smoke gating) is NEAR-NO-OP. smoke.sh is a standalone
bash script; nothing in src/ references it; dist/ carries no smoke
artifacts. Recommend documenting current state + adding optional
no-smoke-in-dist regression test.
- §13: tokens.css line 12 Google Fonts @import migration → 8 local
@font-face rules (Plex variable consolidation collapses the
estimated 12-18 down to 8).
All tooling verified installed on dev machine: rsvg-convert 2.60.0,
pyftsubset 4.63.0, woff2_compress, inkscape 1.4.4. No npm install
needed for execute-plan; only one-off font source TTF downloads.
7 assumptions logged for planner to surface (A1 default_locale, A2
popup DOM rework, A4 Cyrillic serif fallback are highest-impact).
