## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The release workflow publishes canary npm packages on every push to
`master`
> - The failing canary job built successfully and published several
packages before npm failed on `@paperclipai/mcp-server`
> - The concrete failure was npm trusted-publishing provenance returning
`TLOG_CREATE_ENTRY_ERROR` because an equivalent Sigstore
transparency-log entry already existed
> - The package version was not visible on npm afterward, so the release
script could not safely treat that error as success by itself
> - This pull request adds a narrow recovery path for that npm
provenance failure and keeps the existing registry verification as the
final source of truth
> - The benefit is that transient duplicate transparency-log failures do
not break canary publication when a package can be republished without
provenance or is already visible on npm
## Linked Issues or Issue Description
Bug fix, no public GitHub issue found in duplicate search.
- What happened: the Release workflow canary publish failed in
`publish_canary` after npm returned `TLOG_CREATE_ENTRY_ERROR` while
publishing `@paperclipai/mcp-server@2026.609.0-canary.2`.
- Expected behavior: canary publishing should either recover from npm's
duplicate transparency-log failure when the package can still be
published, or fail later in registry verification if the package never
appears.
- Steps to reproduce: inspect
https://github.com/paperclipai/paperclip/actions/runs/27230012891/job/80411422155
from push `05cb18cf28074a6d1074c7575c5a44133146e368`.
- Deployment mode: GitHub Actions Release workflow, npm trusted
publishing.
- Duplicate search: no open PRs or issues found for `canary publish TLOG
provenance release` or the failing run/job IDs.
## What Changed
- Added `publish_package_to_npm` in `scripts/release-lib.sh` to wrap
canary/stable package publishing.
- Detects npm's duplicate Sigstore transparency-log error and checks
whether the package version is already visible on npm.
- Retries that exact package once with `--provenance=false` when npm hit
the duplicate tlog error but the version is not visible yet.
- Keeps unrelated publish failures as hard failures.
- Added shell-helper tests with fake `pnpm` and `npm` commands, and
included them in `pnpm test:release-registry`.
## Verification
- `node --test scripts/release-lib.test.mjs`
- `pnpm test:release-registry`
- Confirmed `pnpm publish --dry-run --no-git-checks --tag canary
--access public --provenance=false` is accepted by pnpm 9.15.4.
## Risks
- Low risk: the recovery only triggers when npm output contains both
`TLOG_CREATE_ENTRY_ERROR` and the duplicate transparency-log message.
- Publishing without provenance is a fallback for canary continuity; if
npm still does not expose the package, the existing registry
verification step still fails the release.
- The same helper is used by stable publishing too, but only for this
exact npm provenance failure path.

This is a release reliability bug fix. I checked `ROADMAP.md`; it does
not duplicate planned core product work.
## Model Used
OpenAI Codex coding agent, GPT-5-class model, tool-enabled local shell
and GitHub CLI workflow, medium reasoning mode.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Its release automation publishes canary packages to npm and then
validates the published registry state before considering the release
healthy
> - The failing canary run `25139465018` showed that npm can expose a
newly published version through version-specific endpoints before the
root package document has fully converged
> - That made a successful canary publish look like a failed release
because the verifier trusted stale root metadata too early
> - This pull request hardens the registry verification path by
preferring version-specific manifest checks, retrying
convergence-sensitive failures, and distinguishing permanent failures
from propagation lag
> - While validating that change in CI, a separate teardown race in
`heartbeat-stale-queue-invalidation.test.ts` surfaced and was hardened
so the PR could pass reliably
> - The benefit is that transient npm propagation lag no longer fails a
successful canary publish, while genuine registry-state and
dependency-integrity failures still stop the release flow promptly
## What Changed
- Hardened `scripts/verify-release-registry-state.mjs` so it prefers
version-specific manifest resolution over stale root metadata, adds
bounded registry-fetch timeouts, and classifies failures as retriable vs
non-retriable.
- Updated `scripts/release-lib.sh` and `scripts/release.sh` so
post-publish registry verification retries only convergence-sensitive
failures and reports immediate permanent failures clearly.
- Expanded `scripts/verify-release-registry-state.test.mjs` with
regression coverage for stale root metadata, fetch timeout behavior,
peer dependency range handling, non-retriable canary-latest cases, and
related verifier edge cases.
- Hardened
`server/src/__tests__/heartbeat-stale-queue-invalidation.test.ts`
teardown to tolerate the late-comment foreign-key race that CI exposed
while validating this branch.
## Verification
- `pnpm run test:release-registry`
- `node --check scripts/verify-release-registry-state.mjs`
- `bash -n scripts/release.sh && bash -n scripts/release-lib.sh`
- PR checks passed on head `5c422600fc12acac61f6b7c267a4dc915df622b1`:
`policy`, `verify`, `e2e`, `security/snyk`, and `Greptile Review`
## Risks
- Low risk. The main behavioral changes are limited to release
automation and verifier retry semantics, plus a test-only teardown
hardening for a CI race.
> I checked [`ROADMAP.md`](ROADMAP.md). This is a narrow release bugfix
and does not overlap planned core feature work.
## Model Used
- OpenAI Codex via Paperclip `codex_local` with tool use and local code
execution enabled. This agent session runs on a GPT-5-class coding
model; the exact backend model ID/context window is not exposed by the
local adapter runtime.
