Live dispatch smoke against the Turbopack dev server (master's ask,
2026-09-19) caught two things unit tests cannot - they run unbundled:
- Bundling pdfjs-dist broke its node fake-worker: the chunk-relative
pdf.worker.mjs import 404s inside .next/dev/server/chunks. Fix:
serverExternalPackages + tracing includes for legacy/ + standard_fonts/
(next.config.ts - a clearly-marked seam, same precedent as bcdcd51; the
standalone output now ships the worker and font files, verified).
- Real-world PDFs warned about missing standardFontDataUrl (non-embedded
standard fonts silently fall back) and flooded the log with JBIG2
warnings on scanned files. Fix: standardFontsDir() + verbosity 0 in
both the node ops and the headless canvas shim.
Verified live end-to-end on GEB (802pp, text layer): teacher dispatch,
12-step read with vision renders, brief with accurate page citations,
wake turn folding the resolution (Chapter IX, pp. 268-270) into the
lesson. Scanned/DRM Polya correctly refuses to fabricate citations.
