 - Hand-written, dependency-minimal codecs over pulling in heavyweight format libraries — see each package's own README for what it deliberately avoids depending on.
-- The foundation and format-codec packages (`byte-codec`, `document-schema.js`, `document-outline.js`, `archive-codec`, `document-compute.js`, `ooxml.js`, `odf.js`, `markdown-codec`, `pdf-codec`, `documents.js`) are Worker-isomorphic: their published `src/` must not import `node:*`/bare Node builtins or use the Node-only `Buffer` global, enforced per-package via an ESLint `no-restricted-imports`/`no-restricted-globals` rule and proven at runtime by a workerd test suite. The interface packages (`document-cli`, `document-mcp`, `documents`) are not held to this, since they legitimately run under Node or a browser rather than needing Worker portability.

The `no-restricted-imports`/`no-restricted-globals` ban enforcing that is defined once in the root's `eslint.shared.ts`, which derives the module list from `node:module`'s own `builtinModules` rather than restating it; a package opts in by passing `isomorphic: true` to `packageLintConfig` rather than declaring the rule itself, and a workerd test suite proves it at runtime.
