No issue — this came out of the release pull request going red on a dependency nothing in the shipped runtime uses.

Problem

The Artifact security job blocked the 2.0.0 release with:

ERR_PNPM_NO_MATCHING_VERSION  No matching version found for @tanstack/query-core@5.102.3
This error happened while installing the dependencies of @pymodel/vis-web@0.1.1
The latest release of @tanstack/query-core is "5.102.2".

@tanstack/react-query@5.102.3 had been published before its query-core peer of the same version was resolvable. pnpm-lock.yaml pins 5.101.4, which was installable throughout — but pnpm deploy --legacy re-resolves from the registry and ignores the lockfile, and says so:

WARN  A pnpm-lock.yaml file exists. The current configuration prohibits to read or write a lockfile

So a mid-publish window at npm, in a dev-only workspace package the desktop runtime never loads, fails a release gate.

What changed

The deploy now runs up to three times with a widening back-off (5s, then 20s).

withDeployRetries takes its clock by injection, so the policy is tested without a real wait or a real registry. A deterministic failure still fails after the attempts run out, and rethrows its own error rather than a wrapper that would hide which command broke.

The trade is explicit: roughly half a minute added to a genuinely broken build, against a release gate that no longer goes red because npm was mid-publish.

What this is not

This treats the symptom. The real question is why a --filter @pymodel/pythinker-code deploy resolves @pymodel/vis-web's dependencies at all — that package is a visual debugging tool, already ignored in .changeset/config.json, and nothing in the packaged runtime imports it. Scoping the deploy would remove the failure class rather than retry it.

That was measured before settling for a retry. Adding --frozen-lockfile and --config.lockfile=true to the legacy deploy is inert: the resulting closure is byte-identical (a diff of the full file lists is empty), and mutating a dependency to a non-existent version still exits 0. Dropping --legacy fails with ERR_PNPM_DEPLOY_NONINJECTED_WORKSPACE, which is why the flag is there. The cold-runner resolution cannot be reproduced on a warm local store, so the scoped fix needs to be developed against CI rather than guessed at here.

[skip changeset] — build tooling only; nothing here reaches the published package.

Summary by CodeRabbit

  • Bug Fixes
    • Improved desktop runtime deployment reliability by automatically retrying failed deployment attempts.
    • Added increasing wait times between retries to help recover from temporary failures.
    • Deployment errors are clearly reported when all retry attempts fail.

`pnpm deploy --legacy` re-resolves from the registry and ignores the lockfile,
so a dependency published in a partially-propagated state fails the desktop
packaging gate even though every pin in the lockfile is installable. That is
what turned the release pull request red: `@tanstack/react-query@5.102.3`
resolved while its `query-core` peer of the same version did not yet, in a
workspace package the shipped runtime never loads.

The deploy now runs up to three times with a widening back-off. A deterministic
failure still fails, and still surfaces its own error rather than a wrapper —
it just costs the waits first. That is the trade: about half a minute added to
a genuinely broken build, against a release gate that no longer goes red
because npm was mid-publish.

This treats the symptom. The resolution should not reach unrelated workspace
packages in the first place; that needs the deploy scoped, which cannot be
verified without a cold CI runner.

📝 Walkthrough

Walkthrough

The desktop runtime deployment now retries failed commands up to three times with 5-second and 20-second backoffs. The retry behavior is configurable and tested for recovery, error propagation, callbacks, and delay ordering.

Changes

Desktop deployment retries

Layer / File(s) Summary
Retry policy and execution helpers
apps/desktop/scripts/stage-runtime.ts, apps/desktop/tests/stage-runtime.spec.ts
The script adds configurable retry helpers with default attempts, 5-second and 20-second backoffs, injected sleep and retry callbacks, and final-error propagation. Tests cover successful attempts, transient failures, callbacks, wait tracking, and exact delay values.
Deployment command integration
apps/desktop/scripts/stage-runtime.ts
The pnpm deployment command uses withDeployRetries with timer-based waiting and warning logs for failed attempts.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 1e747

The staging retry change is localized and mergeable with owner awareness: the current tests do not lock in the documented 5-second and 20-second backoff, so a future edit could retry with incorrect timing and weaken protection against transient registry failures.

The backoff test compared the delay helper against itself and checked only
that the second wait was longer than the first, so a 0ms/1ms backoff would
have passed while retrying faster than a registry propagates.

Assert the five- and twenty-second delays directly.
