Summary

Bumps the @workflow/* packages to the latest 5.0.0 betas, including the spec-version-6 protocol, dense hook-resume convergence, and deterministic adjacent-hook delivery ordering:

  • @workflow/core beta.41 → beta.42
  • @workflow/errors beta.16 → beta.17
  • @workflow/world beta.26 → beta.27
  • @workflow/world-local beta.35 → beta.36
  • @workflow/world-vercel beta.37 → beta.38
  • @workflow/world-postgres (catalog) beta.33 → beta.34

The development world shim forwards to world-local, which now stamps spec version 6, so its advertised specVersion moves 5 → 6 and the drift fixtures move with it.

The failed session-limit eval exposed an intentional behavior change from the combined upstream fixes: world-local hook-resume convergence makes both queued messages visible in a dense log, and core hook ordering preserves those earlier deliveries ahead of the active turn's terminal control. eve then follows its existing contract and coalesces the adjacent ready messages into one follow-up turn. The old eval consumed that boundary as message A and waited forever for a separate message B turn; it now verifies that one message.received contains A then B while the single limit prompt remains pending.

Validation

Both uploaded JUnit artifacts from the failed job timed out at 90.001 seconds after the five queued-A assertions passed, locating the stall at the subsequent queuedBSession.result(). The updated fixture passed pnpm --filter agent-session-limits typecheck; the real-model eval is CI-only and is rerunning on this PR.

Checklist

  • I linked an issue with prior discussion confirming this change is wanted
  • I ran the relevant checks from CONTRIBUTING.md
  • I added tests and documentation where relevant
  • I added a changeset if this touches the published eve package
  • DCO sign-off passes for every commit (git commit --signoff)

Dependency manifests and the lockfile carry the new Workflow betas; the development-world shim advertises their protocol version.

Tests — 3 files · +31 / -38

Protocol drift fixtures move to spec version 6, and the real-model eval now covers the deterministic coalesced delivery shape and arrival order.

core beta.42, errors beta.17, world beta.27, world-local beta.36,
world-vercel beta.38, world-postgres beta.34. The development world
shim advertises spec version 6 (slot-numbered event ids) to match the
updated local world, per the drift guard.

Package Details

  • Package: eve@0.38.1
  • Package directory: packages/eve
  • Tarball: 8.21 MB (eve-0.38.1.tgz)
  • Unpacked payload: 30.85 MB across 3315 published files
  • Installed footprint: 74.38 MB across 7023 installed files
  • Installed root package: 29.49 MB
  • Installed dependencies: 44.88 MB
  • Installed package instances: 35
  • Distinct installed package names: 34
  • Installed dependency edges: 52
  • Installed optional peer edges: 47
  • Runtime dependencies: 2
  • Peer dependencies: 5 (4 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: 2.22 s -> 2.16 s (-60.1 ms) vs main (c358fa9).
  • Timing is informational: shared GitHub runners are too variable for a hard timing budget.

…prove eval

world-local's hook-resume convergence fix makes both queued messages
durably visible when the parked session wakes, so eve's designed
coalescing delivers them as one follow-up turn. The eval's two-turn
expectation encoded the old racy timing where the second hook write
lost the event-slot race and was redelivered later.
