/lib/bare (system image)

Self-contained ctx.bare support on the system Hyperdrive: Holepunch Bare packages bundled as IIFE scripts the booter can execute without a traditional Node module graph on the drive.

What gets staged

  • bare-module-manifest.json — Copy of the booter manifest (same keys and packages as host resolution). Tells the runtime which logical module names exist.
  • manifest.json — Drive loader index: bundles lists IIFE paths that assign into globalThis.__bare_os_stdlib__; bundleStats counts attempted bundles; bundleDiagnostics lists each bundles byte size (same data as docs/audit/bundle-health.json).
  • bundles/*.js — One esbuild IIFE per catalog entry. The bare-libs build is fail-fast (esbuild errors abort; no stub placeholders). Stale *.js left from older tiered builds are pruned on each successful build. Regenerate with npm run build -w bare-os-bare-libs (updates docs/audit/bundle-health.json).

At boot the booter runs drive bundles first, then (unless BARE_OS_BARE_HOST_IMPORTS=0) fills any missing keys via host import() so development iterations can patch a single package without re-seeding the entire drive.


Boot order: drive bundles vs host imports

  1. Seeded bundles win for keys they actually populate — they are part of the trusted image, same class as /bin.
  2. Host imports run only for keys still missing after bundle evaluation, keeping local checkout workflows fast.
  3. Disabling host imports (BARE_OS_BARE_HOST_IMPORTS=0) approximates production Pear behavior where only the drive contents exist.

Environment toggles

The authoritative list is in the environment appendix. Names that operators mention most often alongside /lib/bare:

  • BARE_OS_BARE_HOST_IMPORTS — Set to 0 / false to forbid host import() fallback (drive-only resolution).
  • Related Pear ctx.bare toggles and HTTP allow lists are documented in PEAR-RUN.md and the booter package reference.

Trust model

Trusted image only: executing these bundles is equivalent to running seeded /bin utilities. Do not copy arbitrary third-party IIFEs into kernel/lib/bare/bundles/ without reviewing them the same way you would review a new setuid binary on a Unix system.


Regenerating bundles

  1. Edit packages/bare-os-booter/lib/bare-module-manifest.json or bundle sources under packages/bare-os-bare-libs/ as needed.
  2. Run npm run build -w bare-os-bare-libs — output lands in kernel/lib/bare/ (and CI expects packages/bare-os-seeder/kernel/ to match kernel/ byte-for-byte afterward).
  3. Mirror kernel/ into packages/bare-os-seeder/kernel/ (same tree) so scripts/verify-kernel-seeder-parity.mjs passes — typically rsync -a --delete kernel/ packages/bare-os-seeder/kernel/ from the repo root after init/bundle changes.
  4. Re-run the seeder so peers replicate the updated system drive.

Order with coreutils: from repo root, prefer npm run build -w bare-os-coreutils && npm run build -w bare-os-bare-libs && npm run bundle:kernel before parity check (matches root pretest).


When builds fail

Esbuild prints the failing ctxKey and package. Fix bare-module-manifest.json, adjust build.mjs (plugins, platform), or mark the entry optional / bundle: false when host-only resolution is intended. npm run smoke:bare-manifest guards required imports listed in the manifest smoke list.

CI: scripts/verify-bundle-health.mjs checks docs/audit/bundle-health.json against on-disk sizes; scripts/verify-bundle-markers.mjs and scripts/verify-bundle-throws.mjs gate incomplete-looking substrings / Error messages. scripts/sanitize-bare-bundles.mjs (run from this build) normalizes known upstream HTTP helpers, stream-base-class messages, and ICO encode paths so docs/audit/bundle-marker-allowlist.json and docs/audit/bundle-throw-allowlist.json stay empty.


Note: This file is copied to kernel/lib/bare/README.md (and the vendored seeder tree) by bare-os-bare-libs build. Links are written for the kernel/lib/bare/ path; verify-doc-links skips this template path because its on-disk location differs.
