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: 2.13 s -> 1.95 s (-182.7 ms) vs owen/photon-setup (7ff90c0).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.

Additional Suggestion:

The channel registry validator asserts eve integration setup args using the registry item slug (photon-imessage) instead of the integration setup kind (photon), so the docs build fails at registry:validate:channels.

[vercel]

Scaffolded MCP/OpenAPI connections with header auth emit invalid TypeScript because the object literal is injected into arrow-return position without parentheses, making it a block body.
