Summary

Proposes publishing a workspace through one authoritative SQL metadata transaction after its immutable artifacts are durably uploaded. Release bindings, selections, the catalog generation, and the idempotent outcome commit together; any transaction rollback exposes none of the batch.

Uses the portable metadata contract from #48. Specifies authorization conflict detection through a policy epoch or equivalent serializable validation, recovery after a lost commit acknowledgement, and the SQL/object-storage boundary. Backend replacement must preserve generations and idempotent outcomes.

Every committed transaction that publishes versions is recorded as a readable publication: its members across ecosystems, its publisher and commit, and an optional name such as v12.0.0, served at /-/publications/<org>/<id-or-name> and filtered by the caller's read access. Release notes for a whole publication (#56) attach to it.

A transaction is scoped to one organization's hosted catalog and covers every ecosystem pnpr hosts, not npm alone. Clients that send no idempotency key are matched by content: a single publish by its archive, manifest and tag changes, a batch by a digest over all of its entries. Idempotency outcomes are kept for at least 7 days. pnpr keeps the current generation and any generation a snapshot read has pinned. A publication's name is not an idempotency key.

Snapshot-aware resolution pins a committed generation. Separate requests from ordinary clients to live registry endpoints retain their documented weaker consistency.

Validation

• Reviewed against the existing pnpr routing, revision, resolver/cache, and publication contracts.
• Prose lint, whitespace checks, RFC template sections, draft status, local links, and agent attribution pass.
• Only RFC text changed. Backend conformance suites and benchmarks are implementation requirements, not tests run in this PR.

Open questions

The versioned SQL schema with each backend's policy-epoch locking, and the contention and storage measurements that must pass before this becomes the default publication path, are left to the prototype. Transaction scope, ecosystem coverage, keyless batches, the name-versus-key question, and retention are settled in the text.

- Around line 112-116: Update Step 5 to include publication and

catalog generation, ensuring publication metadata is committed before advancing
the catalog’s current reference.
- Around line 171-174: Update the keyless idempotency check for publishing
name@version to account for tag and revision-selection mutations as well as
archive integrity and accepted manifest; hash the complete mutation or reject
replay when those selections differ, while preserving recorded success for an
identical mutation.
- Around line 345-351: Update the backend replacement procedure to define an
atomic stop, drain, and export barrier: stop accepting hosted writes, resolve
every in-flight transaction before export by either committing it or failing it,
then export only after that resolution is complete. Specify that committed
generations and idempotent outcomes are included in the export, and failed
transactions must revalidate against the replacement before retrying.
- Around line 103-109: Clarify the authorization policy in the publication flow
around the idempotency claim: allow the original stable principal to recover an
already committed identical request’s outcome after its mutation permission is
revoked, while continuing to require current authorization for new mutations.
Specify how the retry identifies and verifies that principal without weakening
authorization for other requests.

Walkthrough

This pull request adds an unapproved draft RFC for atomic workspace publication through a hosted catalog. It describes proposed artifact staging, catalog transactions, idempotency, generation-pinned reads, publication records, recovery, and implementation questions. It does not implement or approve a protocol.

Changes: Atomic publication proposal

Layer / File(s)	Summary
Publication model and commit flow pnpr/text/0000-atomic-workspace-publication.md	The draft identifies current publication gaps and proposes SQL metadata as the catalog authority. It describes staging and verifying artifacts before a transaction commits a batch, advances the generation, and records an outcome. It also specifies conflict handling and idempotent retries.
Snapshot reads, publication records, and recovery pnpr/text/0000-atomic-workspace-publication.md	The draft describes generation-pinned reads, access-filtered publication lookup routes, crash recovery, authorization, and artifact-retention rules.
Storage constraints and implementation scope pnpr/text/0000-atomic-workspace-publication.md	The draft compares storage approaches and lists implementation steps, validation requirements, prior art, and unresolved questions.

Estimated code review effort: 2 (Simple) | ~10 minutes

Explanation

The title "rfc(pnpr): atomic workspace publication" names the main change: a draft RFC proposing atomic publication of workspace batches for pnpr. The changeset adds only the RFC document, so the title matches the primary subject. It is short, specific, and follows the conventional prefix style.

And finds one batch kept whole and tight
The catalog marks a generation new
While staged-up bundles wait their cue
I nibble notes on reads and retries

This remains a draft for discussion. Before ratification, choose the catalog/coordinator design and prove atomic authorization checks, durable outcomes, backend guarantees, and acceptable contention. Separate live client requests do not gain snapshot isolation automatically.

Companion drafts: #44, #45.

Updated in 281755f. Changed publication to commit all metadata and idempotent outcomes in one SQL transaction after artifact upload. Added explicit policy conflict validation, lost-acknowledgement recovery, and backend conformance requirements.

This remains a draft. The versioned SQL schema, backend-specific policy-epoch validation, initial transaction scope, retry/retention periods, and contention/storage measurements need design review before ratification.

Prose lint and document checks pass.

Updated in f0f8901.

• Added npm tracker evidence: 78 "cannot publish over" / EPUBLISHCONFLICT issues and half-published workspace releases.
• Named the pnpr gaps the transaction must close, checked in code:
  • A byte-identical retry returns VersionAlreadyPublished.
  • Every archive travels in one body under the 100 MiB limit.
  • OIDC workloads can only PUT a single package, with no batch and no dist-tags.
• Archives are uploaded by integrity before commit. For clients that send no idempotency key, the content is the key. Workloads can submit transactions, and staging can hold a whole transaction.

High-Level Assessment

The following are alternative approaches to this PR:

1. Retain journaled per-package publication

• ➕ Reuses the existing publication and recovery path.
• ➖ Concurrent readers can observe partial batches, and late conflicts can leave partial releases.

2. Commit an object-store catalog pointer

• ➕ A compare-and-swap could expose one immutable catalog generation.
• ➖ Policy validation, idempotency outcomes, and recovery would still require coordinated authoritative state.

Recommendation: The proposed SQL authority is the stronger fit for committing bindings, policy-validated selections, generations, and outcomes together. Keep the RFC in draft until backend isolation mechanisms, retention periods, and contention costs are specified and validated.

- Around line 112-113: Update step 5 of the commit sequence to advance the
catalog’s current reference to the new generation within the same transaction,
conditional on the reference still naming the generation read in step 4; on
mismatch, roll back the transaction.
- Around line 204-207: Clarify how releases created before publication records
are introduced will be handled. Define a backfill that assigns each existing
package version to exactly one publication, or narrow the invariant to new
publications and specify legacy behavior for member lookup and the `publication`
field.
- Around line 337-341: Update the backend replacement requirements in the
publication conformance suite to define policy-epoch handling: preserve the
policy epoch across replacement, or require transactions started before
replacement to revalidate before commit.
- Around line 132-134: Update the RFC section describing artifact uploads to
match the shipped contract: use POST /-/pnpr/v0/artifacts/blob for blob upload
and PUT /-/pnpr/v0/artifacts for publication. Do not describe PUT and HEAD on
the blob endpoint as existing shipped endpoints.
