Summary

Intermittent Actions failures came from shared test state, buffered events, fixture dependency resolution, nondeterministic evals, and scaffold installs racing npm publication. This PR fixes those conditions, adds bounded Windows workflow-read retries, preserves pending tasks through compaction, and retains scripted mock responders. The scaffold test now installs the local eve tarball while preserving the 48-hour registry release-age policy; production scaffolding, authorization and ordering assertions, and the default E2E matrix are unchanged. Scope remains limited to fixes and regression coverage, with general repetition tools, manual CI controls, and unproven dev-server diagnostics excluded.

Workflow Release

The temporary Workflow patch remains necessary until a release containing vercel/workflow#4051 is available and adopted. This PR keeps the patch in place.

Validation

Latest scaffold publication-race fix (a6b5c5c77):

• The focused release-age scenario passed in the ordinary environment.
• pnpm --filter eve exec vitest run --config vitest.scenario.config.ts test/scenarios/eve-init.scenario.test.ts --retry=0, with GITHUB_HEAD_REF=changeset-release/main and a local pnpm store: all 10 tests passed, none skipped.
• Regression coverage exercises an intentionally unpublished eve dependency range, verifies the local-tarball override, and checks that the generated project retains strict release-age policy without added exclusions. The obsolete release-branch skip is removed.
• pnpm --filter eve exec tsc -p tsconfig.json --noEmit, targeted formatting/lint, pnpm guard:invariants, and the whitespace check passed.
• The full scenario suite was not rerun for this single-file fix.

CI and the Local, Vercel, and Postgres E2E workflows passed on 5f9547b2a, before the scope cleanup and latest scaffold fix.

After scope cleanup, before the latest scaffold fix:

• pnpm --filter agent-channels test:unit: 3 deployment-revision regression tests passed.
• pnpm --filter eve exec vitest run --config vitest.unit.config.ts --maxWorkers=4 --silent: 8,415 passed; 1 existing skip.
• pnpm --filter eve exec tsc -p tsconfig.json --noEmit: passed.
• pnpm guard:invariants: passed. Targeted formatting and lint passed.
• The restored workflow and discovery script match main byte-for-byte. Default discovery output is unchanged: 37 model-suite jobs and 29 fixture jobs per world.
• No references to the removed repetition tooling remain. The task-reporting experiment is already on main and is not part of this PR's diff.

Earlier fix validation included 44 successful workspace typecheck tasks, 765 integration tests, and local shuffled repetition samples. The recorded samples are evidence for their selected tests, not proof that every possible CI flake is eliminated. Their runners and raw evidence are not part of this PR.

Full E2E suites run only in CI. Earlier green runs do not establish current-head CI status; required checks must pass on the latest head before merge. No existing E2E assertion or default matrix leg was removed.

Checklist

• 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 pushed commit (git commit --signoff)

Package Drill-Down

Package Details

• Package: eve@0.52.4
• Package directory: packages/eve
• Tarball: 8.70 MB (eve-0.52.4.tgz)
• Unpacked payload: 32.77 MB across 3911 published files
• Installed footprint: 77.91 MB across 7814 installed files
• Installed root package: 31.34 MB
• Installed dependencies: 46.56 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: 5.86 s -> 5.95 s (+88.6 ms) vs main (6435811).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.
