rfc(pnpr): flat entries, declared registries, and revisions in pnpr's package document by zkochan · Pull Request #55 · pnpm/rfcs

zkochan · 2026-10-31T23:00:28Z

Summary

A follow-up to the merged split packuments RFC (#54): it flattens the entries of pnpr's package document and keeps pnpr's fields out of npm's documents.

Flat entries. Before, a complete entry nested npm's version object (manifest.dist.pnpr.variants). Now the entry's top level holds pnpr's facts about the archives: integrity, fileCount, unpackedSize, requiresBuild, bins and variants. They sit next to the mutable state (deprecated, trust, revision) and the publish time. manifest is only the publisher's manifest, without dist, name or version.
No namespaces. Nothing but pnpm reads this format, so every top-level name belongs to pnpr. There is no dist and no pnpr key, and revision appears once.
Release record. The record at <name>/<version>+r<revision> becomes { name, version, <facts>, manifest }, the same parts a complete entry has.
npm's documents. They no longer carry dist.pnpr or variants. pnpm releases that read dist.pnpr.requiresBuild and bins from them fall back to reading both from the archive, as with any registry. pnpr is experimental, so the server and client change together.
Only declared registries. pnpm asks for pnpr's format only from registries declared serverType: pnpr, and caches those documents in a directory of their own. pnpr sends a pnpr-registry header so pnpm can warn about an undeclared pnpr.
Revisions. npm's documents give a selected revision by its +r<N> tarball URL and integrity only. pnpr's format marks revision-aware versions with revision, including 0, and every revision in the history has a release record. The merged patch-revisions RFC gets an amendment saying so: a status note, invariant 3, and a new section that replaces where the other sections place dist.revision and dist.revisions.
Manifest verification RFC. One mention of dist.pnpr.requiresBuild becomes requiresBuild.

Implemented in pnpm/pnpm#17522. The variant scenarios (esbuild, biome, typst, a Tailwind app and server-side resolution) install, build and run through the flat format, both with only large documents split and with every document split. The lockfiles match earlier runs apart from tarball URLs, which pnpm omits once the registry is declared serverType: pnpr.

Summary by CodeRabbit

Documentation
- Clarified that pnpr build requirements are derived from the verified archive.
- Updated registry guidance: pnpm requests the pnpr format only from explicitly identified pnpr registries; other or undeclared registries use npm documents, with a warning when an undeclared registry identifies itself as pnpr.
- Explained how version entries and release records represent archive facts, manifests, and mutable state, including revision overrides and revision zero.
- Clarified that npm documents omit pnpr-specific facts, advertise the selected artifact through its revision URL and integrity, and do not include revision fields.
- Documented that pnpr revision markers guide URL construction, while immutable release records hold revision history and the audit surface retains status and provenance.

An entry and a release record give pnpr's facts about the archives (integrity, fileCount, unpackedSize, requiresBuild, bins, variants) at their top level, beside the publisher's manifest, with no dist or pnpr namespace. npm's documents served by pnpr no longer carry dist.pnpr.

Walkthrough

The RFCs revise registry format selection, version-entry and release-record fields, and revision representation and resolution. They also update archive-derived build metadata wording and specify implementation and test expectations.

Changes: pnpr document protocol

Layer / File(s)	Summary
Registry format selection `pnpr/text/0000-split-packuments.md`	The RFC limits pnpr media types to registries declared `serverType: pnpr`. Other and undeclared registries use npm documents. pnpr identifies itself with `pnpr-registry`, which prompts a warning when the registry is undeclared.
Entry and release-record shape `pnpr/text/0000-split-packuments.md`	The RFC puts archive facts and `requiresBuild` at the version-entry level, separate from the manifest and mutable state. It defines complete entries and release records, including the manifest and archive facts.
Revision representation and resolution `pnpr/text/0000-integrity-addressed-patch-revisions.md`, `pnpr/text/0000-split-packuments.md`	The RFC puts revision markers in pnpr documents and uses tarball URLs and integrity in npm documents. It moves revision history to release records and describes revision overrides, revision-zero selection, and lockfile data.
Archive metadata and validation `pnpr/text/0000-publish-manifest-verification.md`, `pnpr/text/0000-integrity-addressed-patch-revisions.md`, `pnpr/text/0000-split-packuments.md`	The text says `requiresBuild` derives from the verified archive. It updates requirements and test expectations for document formats, revision selection, release records, and undeclared registries.

Merge Risk: Minimal · up to d971d

This RFC change defines how pnpm negotiates pnpr documents and how revisions and release records are represented. The wording is consistent across both RFCs, and no unresolved issue remains that should block merging.

Full details: Title check

Explanation

The title names the RFC (rfc(pnpr)) and three changes: flat entries, declared registries, and revisions in pnpr's package document. The changeset and objectives match these points. The main change is a follow-up RFC that flattens the package document format, limits the new format to registries declared serverType pnpr, and moves revision handling into pnpr's package document. The title is long (86 characters, 11 words) and lists three topics, but it is specific and relates to the main change.

While manifests sit by design.

Define flat pnpr package entries and release records

📝 Documentation 🕐 10-20 Minutes

AI Description

• Define flat pnpr entries that separate archive facts and mutable state from the publisher’s
 manifest.
• Align immutable release records with complete entries and exclude pnpr-specific fields from npm
 documents.
• Update the manifest-verification RFC to use the flat requiresBuild field.

  Registry --> Npm["npm document"]

High-Level Assessment

The flat, pnpr-only entry is appropriate for a media type consumed by pnpm alone: it distinguishes publisher metadata from registry-derived facts without retaining an unnecessary dist.pnpr namespace. Keeping those facts in an immutable release record also preserves the split-document design; retaining npm-shaped nesting would add complexity without improving compatibility.

scoped supersession note as a pointer to the amended schema, not as its sole
definition.

- Around line 346-347: Update the lockfile description in the split-packuments
proposal: ordinary entries retain their current shape, while revision-aware
entries record both integrity and revision, including revision 0, so frozen
installs can reproduce the selected revision.
- Around line 141-142: Update the release-record URL contract for ordinary
versions so clients can fetch a split entry when its manifest is omitted; define
a non-revision route distinct from the revision-aware `+r<revision>` route,
reserving `+r0` for revision-aware entries.
