fix(eve): support lazy metadata in Workflow beta update by roboeve[bot] · Pull Request #3233 · vercel/eve

roboeve · 2026-09-10T15:09:16Z

Adopt the released Workflow Windows retry while preserving session inbox capability negotiation with the updated SDK.

Why

@workflow/world-local@5.0.0-beta.42 required an eve-local patch for transient Windows read failures. Workflow PR #4051 released that fix in beta.43.

The aligned package update also includes @workflow/core@5.0.0-beta.50. That release exposes hook.metadata as a lazy Promise. eve read it synchronously, so current inbox hooks appeared markerless. CI then downgraded session-owned cancellation to wire version 0 and failed to detect workflow-task authorization support.

Changes

Update the aligned Workflow beta packages and remove the obsolete local patch
Await hook metadata when negotiating inbox wire versions and authorization support
Preserve raw and stable inbox fast paths that do not need metadata
Model lazy metadata in unit tests and await it in the integration assertion

Hypothesis

Awaiting the memoized metadata before inspecting capability stamps restores wire version 6 and authorization behavior without adding metadata hydration to the existing fast paths.

Package Drill-Down

Package Details

Package: eve@0.52.5
Package directory: packages/eve
Tarball: 8.73 MB (eve-0.52.5.tgz)
Unpacked payload: 32.90 MB across 3919 published files
Installed footprint: 78.39 MB across 7836 installed files
Installed root package: 31.47 MB
Installed dependencies: 46.91 MB
Installed package instances: 33
Distinct installed package names: 32
Installed dependency edges: 51
Installed optional peer edges: 8
Runtime dependencies: 2
Peer dependencies: 6 (5 optional)

Installed footprint is measured from an isolated temporary npm install of the packed tarball.
Graph metrics read only package.json files in package directories directly beneath a node_modules boundary, including nested boundaries. Each directory is one package instance; distinct names come from those manifests. Dependency edges count each unique name in dependencies or optionalDependencies per instance; optional peer edges count peerDependencies marked optional.

Build Timing: `e2e/fixtures/agent-tools-sandbox`

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

Build pipeline: 6.05 s -> 5.97 s (-85.7 ms) vs main (2b2ad19).
Timing is informational: shared GitHub runners are too variable for a hard timing budget.
