Handoff

Spec §11.5.1 / §21.5: an OD run isn't done when the artifact exists — it's done when the artifact reaches the surface the user will keep iterating on. This atom is the "push it somewhere" stage. It's the natural counterpart to diff-review.

Inputs

• The accepted artifact set (after diff-review resolved with decision: 'accept' | 'partial').
• The export target (one of the surface enum values from ArtifactManifest.exportTargets[].surface).

Surfaces

surface	typical follow-on
cli	the user runs od files read against the project; no extra push
desktop	open the project in the OD desktop app
web	publish to the public marketplace via spec §13's od:// deep link
docker	wrap the artifact into a self-contained container (calls the §15.4 image)
github	open a PR via od plugin publish --to <catalog>
figma	round-trip back into the figma-migration source file
code-agent	hand off to Cursor / Claude Code / Codex sitting on top of the project cwd

Output

Updates ArtifactManifest.exportTargets[] with a row per push, appending — never replacing — so the artifact's distribution history stays append-only.

Convergence

The atom completes when at least one exportTargets[] entry matches the user's intent or the user explicitly skipped via the confirmation GenUI surface.

Anti-patterns the prompt fragment forbids

• Pushing the artifact to a surface that wasn't on the user's intent list.
• Mutating sourcePluginSnapshotId (it's immutable; the export trail is additive).
• Treating figma as a no-op when the user's source was a Figma file — round-trip is the whole point of the figma-migration scenario.

Status

Implemented by the daemon runner in apps/daemon/src/plugins/atoms/handoff.ts. It records provenance, handoffKind, and export targets, then persists the updated artifact manifest.
