fix(eve): offer to repair failed self-modifications

[benpankow]

Summary

When a self-modification later fails or behaves incorrectly, the parent now offers to send it back to self-mod for repair. For now this is conservative: it requires confirmation and only applies to failures tied to a prior self-modification. We may want to offer self-mod repair after any tool failure once we have a good way to avoid irrelevant suggestions.

Validation

Adds a unit test for the repair offer and confirmation requirement.

Package Drill-Down

Package Details

• Package: eve@0.54.2
• Package directory: packages/eve
• Tarball: 8.76 MB (eve-0.54.2.tgz)
• Unpacked payload: 33.01 MB across 3945 published files
• Installed footprint: 78.50 MB across 7862 installed files
• Installed root package: 31.58 MB
• Installed dependencies: 46.92 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: 4.16 s -> 3.96 s (-196.6 ms) vs main (109a699).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.

The release note addresses readers as “users” twice and the first sentence is long and indirect. Please use direct address and tighten the behavior description. For example: “When a self-modification later fails or behaves incorrectly, the agent now offers to delegate a repair. It waits for your confirmation before starting.”
