Reviewing the RFCs merged to main from October 31 through November 2 found a sound shared architecture, with several contracts that need refinement before implementation. This updates seven RFCs in place. Immutable archive-derived records, transactional SQL metadata, generation-based views, split documents, and complete platform archives remain the foundation.

Review coverage

Merged work	Assessment and resulting change
#48 — SQL metadata	Keep the domain interface and SQLite-first approach. Use the same catalog-scoped generation and idempotency namespace as atomic publication, avoiding a contradictory global counter.
#47 — manifest verification	Keep archive-derived acceptance. Restrict the benign normalization exception to the specific implicit-build script and flag; it must not excuse arbitrary script differences.
#54 — split packuments	Keep the cacheable split and likely picks. Keep the 30-day policy limit for the windowed format and make the existing time-based approximation outside the window explicit. No paired metadata reads or source-identity protocol is needed.
#55 — flat entries and revisions	Keep declared registries, separate client caches, explicit revision zero, and immutable historical records. Reviewed the amendments to the patch-revisions RFC; no further change to that protocol is needed here.
#46 — atomic publication	Keep the SQL commit boundary and generation reads. Match retries using the existing retained request digest and outcome; after expiry, conflict when the original result cannot be recovered. Model later Python distribution uploads as artifact publications while retaining one initial publication per version.
#51 — platform variants	Keep complete archives and platform-neutral locking. Rank each variant's best matching target at install time: one array order cannot implement the stated rule for every host. Preserve resolved graph and peer context alongside archive integrity in virtual-store identity.
#49 — release records	Keep records, existing transparency formats, DSSE, and TUF. Apply existing read policies to entry tiles, use standard TUF policy distribution and dual-threshold root rotation, define proof-pending behavior, and verify Python artifacts individually. Regenerate statements from authoritative SQL records after statement-key compromise; unavailable authoritative data leaves evidence unavailable.
#56 — release notes	Keep mutable notes outside install metadata and the initial-digest check for versioning intent cleanup. Clarify initial versus later artifact publications; later uploads use the existing note-edit routes to change version notes. Reviewed the associated monorepo-versioning amendment; its note-GC contract remains appropriate.
#57, #58, #59 — links and closed-draft cleanup	Keep the merged-file links and removal of the closed snapshot draft. No additional structural changes needed.

Concrete failure cases addressed

• A reader authorized for one package could fetch a raw log data tile containing another package's name and version. Bulk entry access now requires existing read permission for every entry returned; ordinary package reads receive their own leaf and proof. Hash-only witnesses and full-log identity monitors have different duties. Publicly disclosed history cannot be made secret by purging a CDN.
• After retry records expire, identical archive bytes cannot distinguish a replay from a request with changed tags, notes, publication name, or batch membership. Use the retained whole-request digest and original outcome without reapplying selections; conflict when expiry leaves insufficient information.
• Variant A can cover a generic Linux target and a higher-specificity macOS target, while B covers the reverse. Linux must prefer B and macOS A. A first-match selector cannot satisfy both. The RFC includes the counterexample and reuses acceptedLockfileFormats to negotiate the lockfile version that defines those selector semantics.
• Two projects can install the same archive but resolve its dependency ranges differently. Archive integrity must augment, rather than replace, graph and peer-context identity.
• A dynamic source distribution can have different metadata from a wheel with the same version. Verification follows the selected artifact; a matching version alone cannot transfer verification.
• A second wheel upload must not claim the first upload's publisher or change an earlier publication's membership or initial note digest.
• A SQL commit can succeed while log integration or witnessing is delayed. Treat this as committed with proofs pending, rather than absent or failed publication.
• A compromised statement key can forge publication evidence for an already logged record. Regenerate registry statements from authoritative acceptance and publication records through the existing statement-generation path. Do not accept the compromised key's envelopes as the source of publisher claims.

Basis and implementation limits

Applied the project's PHILOSOPHY.md: security, performance, disk efficiency, predictability, and consolidation before adding independent mechanisms. Inspected current pnpr storage, publication validation, batch/journal behavior, package access, Cargo/Python surfaces, and the client's variations selector at pnpm/pnpm commit b003905dd9ad40d9e9bacf1be635f7527eb2b907. In particular:

• Current batch commit and partial-read contract
• Current duplicate-publication guard
• Current first-match variations selector

Checked the relevant primary specifications: TUF client workflow, C2SP tiled logs, and PEP 643 dynamic metadata.

The split-document prototype's performance results do not establish the cost of default verification, which fetches every selected record and proof, or eager upstream archive derivation. Those need measurements before release. Isolation details for each SQL backend, integration/freshness limits, and compatibility client matrices remain implementation gates. This PR makes no new benchmark claims and does not implement the protocols.

The proposal reuses acceptedLockfileFormats and the existing incompatible-format error, package read policies, SQL publication outcomes, statement generation, and note-edit routes. It adds no separate resolver capability exchange, log-auditor role, permanent retry-record requirement, recovery archive protocol, or inline version-note editing mechanism.

Validation

• git diff --check passes.
• All 48 relative Markdown file links in the seven changed RFCs resolve.
• An executable counterexample confirms the conflicting multi-target variant ordering. Release-age filtering stays within the retained 30-day window; time-based resolution outside the window explicitly retains its existing approximation.
• Added conformance requirements for the security, retry, publication, selector, and bounded timestamp cases above. Runtime tests were not run for this documentation-only change.

Written by an agent (Codex).

Summary by CodeRabbit

• Documentation
  • Clarified how publication retries are matched, when expired outcomes can be replayed, and how publication records link Python and OCI artifacts.
  • Updated platform variant ranking, lockfile compatibility, and which variants are fetched or linked when metadata is incomplete.
  • Specified release-age behavior for missing and unknown publish times, including the supported setting limit.
  • Clarified publication evidence for imported history and Python uploads, transparency-log access and verification, and publisher-side manifest validation.
  • Documented catalog-scoped publication outcomes and read-after-write generations.

Walkthrough

This PR revises seven RFC documents. The changes cover publication retries and artifact records, release-note and verification rules, platform variant selection, manifest normalization, and publish-time handling in split package metadata.

Changes: Publication and release evidence

Layer / File(s)	Summary
Catalog-scoped publication retries pnpr/text/0000-atomic-workspace-publication.md, pnpr/text/0000-sql-metadata-storage.md	Idempotency keys, publication outcomes, and generation counters use hosted-catalog scope. Request digests include publication details and selection changes. After outcome retention expires, a retry succeeds only when the original request and outcome remain recoverable; otherwise, it conflicts.
Artifact publications and release notes pnpr/text/0000-atomic-workspace-publication.md, pnpr/text/0000-release-notes.md	Publication records identify accepted artifacts, including later Python distributions. The rules distinguish initial version publications and notes from later artifact publications and notes.
Release-record policy and verification pnpr/text/0000-release-records.md	The proposal specifies log identity, witness and disclosure rules, proof readiness, TUF policy and recovery, and artifact-specific verification. It also updates implementation steps, conformance cases, and unresolved requirements.

Platform variant resolution

Layer / File(s)	Summary
Variant matching and selection pnpr/text/0000-platform-variants.md	The proposal ranks matching targets independently of array order and rejects highest-score ties. A lockfile marker distinguishes the new selection semantics. Fetching and linking use different requirements for unstated floors and ABI values.
Variant identity and format negotiation pnpr/text/0000-platform-variants.md	Virtual-store identity includes archive integrity and resolved dependency-graph and peer-context identity. When variants are required, the resolver checks accepted lockfile formats and returns an incompatibility error rather than downgrading to the primary.

Publish manifest verification

Layer / File(s)	Summary
Bounded normalization exception pnpr/text/0000-publish-manifest-verification.md	The exception covers an added install: "node-gyp rebuild" and gypfile flag only when there are no other lifecycle-script differences and archive inspection finds no implicit build.

Split package metadata

Layer / File(s)	Summary
Publish-time rules and validation pnpr/text/0000-split-packuments.md	Omitted publish times indicate that a version predates timesSince; null times remain unknown. The format supports minimum release ages up to 30 days and defines time-based cutoff behavior on both sides of timesSince.

High-Level Assessment

Refining the existing RFCs in place is appropriate: implementers need one consistent contract at each feature boundary. A separate cross-RFC addendum would leave conflicting instructions in the source documents.

Review comments at @pnpr/text/0000-atomic-workspace-publication.md:
- Around line 282-286: Revise the filename lookup and publication-evidence
contract so a synthetic publication grouping historical artifacts is not
presented as verified evidence of when a distribution was introduced. Where
historical records lack that provenance, mark the evidence as imported or
unavailable, or explicitly define the result as a best-known historical link;
preserve the claim of an introducing publication only when the records establish
it.
- Around line 206-209: Update the concrete keyless batch digest rule to include
publication names, publication notes, and version notes, either as explicit
digest inputs or within the accepted-manifest input. Keep the existing compact
commitment behavior unchanged.

Review comments at @pnpr/text/0000-platform-variants.md:
- Around line 410-413: Define a total, deterministic ranking for variant matches
in the selector: specify how absent values compare with present values for each
ranked field, including libcVersion, and establish precedence between napi and
nodeAbi. Alternatively, reject incomparable overlapping targets before clients
rely on selection; preserve the platform-neutral lockfile ordering by derived
tags.
- Around line 578-579: Update the resolver negotiation requirements in the
lockfile documentation to define a named capability that clients advertise for
the new lockfile version and selector semantics. Require pnpr to return an
explicit incompatibility error when the capability is absent, rather than
returning variant entries or silently downgrading to primary-only metadata.

Review comments at @pnpr/text/0000-release-records.md:
- Around line 336-339: Update the transparency-log guarantee in the summary to
distinguish policies with the required witness quorum from unwitnessed private
registries. Claim global consistency only when the quorum is met; otherwise
state that clients can detect rewrites of their own observed history but not
split views.
- Around line 462-466: Clarify the pre-compromise re-signing rule in the
release-record guidance by defining which archived evidence artifact is trusted,
how clients authenticate it, and how clients verify the compromise cut-off;
require the exact statement digest to be authenticated before that cut-off. Add
conformance cases covering a valid archived pre-compromise statement, a forged
statement for an old record, and re-signing after key rotation, without
accepting evidence that fails the defined checks.

Review comments at @pnpr/text/0000-split-packuments.md:
- Around line 193-195: Update the surrounding `timesSince` wording to define it
as an upper bound for entries without `time`, not as their publication
timestamp. Preserve the rule that cutoffs at or after `timesSince` can use the
bound, while earlier cutoffs require fetching exact times before evaluating
which versions qualify.

187-189: Keep timesSince as an upper bound.

The first paragraph still says that an omitted time is treated as published at timesSince. The later rule requires exact timestamps for earlier cutoffs. Following the first rule can reject a version that qualifies by its actual publish time and can change time-based resolution.

This is the same unresolved issue as the previous review comment at lines 193-195. (raw.githubusercontent.com)

Learning: Within repository "pnpm/rfcs", only for files matching one of ["pnpr/text/0000-split-packuments.md"]: When reviewing publish-time handling in pnpr/text/0000-split-packuments.md, distinguish an omitted time field in pnpr.otherVersions from explicit time: null. Verify that omitted time means publication before pnpr.timesSince and passes every supported minimum release age, while null means unknown age and follows minimumReleaseAgeIgnoreMissingTime. Require separate expected test results for an in-window timestamp, omitted time, and null.
