Package Details
- Package:
eve@0.44.3 - Package directory:
packages/eve - Tarball: 8.20 MB (
eve-0.44.3.tgz) - Unpacked payload: 30.84 MB across 3418 published files
- Installed footprint: 75.03 MB across 7132 installed files
- Installed root package: 29.49 MB
- Installed dependencies: 45.55 MB
- Installed package instances: 35
- Distinct installed package names: 34
- Installed dependency edges: 53
- 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.

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: 2.05 s -> 2.25 s (+204.8 ms) vs
main (05f002b). - Timing is informational: shared GitHub runners are too variable for a hard timing budget.

Summary
Workflow execution currently hard-codes one agent-loop step per durable Workflow step. This adds a single internal limit and makes continuation batching preserve per-step setup, cooperative cancellation, steering, and physical-step retry semantics, while leaving the limit at
1; a temporary10canary was reverted after exposing a Postgres-world cancellation limitation.Before starting another logical step, eve journals the completed session/context to a Workflow stream scoped by the physical step's stable
stepId. A physical retry resumes from the latest journal entry; an empty journal immediately replays logical step 1. Sleep, background-task launch, HITL, authorization, and runtime-action results remain batching barriers.Background task readiness is modeled as an explicit generic
commitBarrierrather than inferred from task fields.turnStepowns both the barrier transition and the state safe for cancellation;turnWorkflowonly persists the transition and executes the typed post-commit effect.Validation
A temporary
N=10CI canary passed core CI, all Local E2E, all Vercel E2E, and 21/23 Postgres fixtures. Postgres cancellation and cancelled-first-turn dynamic-model evals timed out because that world did not deliver live cancellation into the long-running first physical step; the limit was restored to1rather than weakening cancellation semantics.The production-default focused suites, package typecheck/build, formatting, lint, and invariant guard pass. A temporary
N=10canary passed the full unit suite (667 files; 7,052 tests passed, 1 skipped), all durable-session/checkpoint retry integration tests (5), and real Workflow steering/direct-cancellation integration tests (2; the remaining sandbox-backed cases are left to clean CI because the local microsandbox migration database is stale).Checklist
