docs/plans/p5a: 01 kind+fetch limits, 02 pdftext child + runner, 03 dcache PDF tables, 04 pdfpool, 05 pdfdoc render (map/pages/grep), 06 api, 07 digest citations, metrics, CLI, skill, unit, README. Given tests compile against a panic-only skeleton and fail there for the intended reasons; PDFs for tests are built by internal/pdftest (given), plus two qpdf-encrypted fixtures. Owner changes for the run: vendor go-pdfkit/extract v0.3.0 + reader v0.6.0 (pinned via tools.go until task 02); AGENTS.md, tools/run-plan.sh (enforces a Co-Authored-By trailer for the model), docs/implementer-log.md, `make gate`; gofmt (whitespace) on clean.go and guard; TestUnsupportedType uses a zip now that PDFs are supported; requestDeadline 90→210 s and writeTimeout 120→240 s for the PDF path's worst case.

// greekAndMathRunes are the names a mathematical document gives its glyphs.
