Public X video proof wired

Builder: @jk_drq

Primary piano Space used as links.video / links.share:

• Distorted Face Piano — https://x.com/i/spaces/1dKrPPWnNDzJX

Manifest notes:

• visual.videoLabel names X

If you have additional piano Space URLs/status clips on @jk_drq that should be listed alongside this one, drop them in-thread and I’ll append artifacts.

Pipeline is green on the fork — needs workflow approval upstream

Pushed 1998f69, which adds a package-scoped CI workflow and declares the builder association.

What's in the commit

• .github/workflows/showcase-acp-sdk-v2-to-v3-migration.yml — gated on showcase/acp-sdk-v2-to-v3-migration/**
• showcase.json — builder.association: "champion", asserted in CI

Steps the workflow runs

1. node scripts/validate-showcase.mjs — manifest validation
2. node --check on v3-provider.mjs, v3-client.mjs, phase-event-map.mjs, v2-provider.legacy.mjs
3. npm run check — 10 offline self-check assertions
4. Skill installability into ~/.agents/skills and ~/.claude/skills
5. Proof artifact presence — piano Spaces notes, offline validation receipt, Telegram notes, poster, soul.md

Result on the fork — run 30723206354, job package self-check, success, all 10 steps passing:

github author_association : N/A
declared association      : champion
builder.association = champion
Validated 55 showcase project manifest(s).
10 checks passed

On association — GitHub's author_association is derived from repository permissions and cannot be set by a contributor. champion is a manifest-level declaration only. The workflow prints GitHub's derived value alongside the declared one in the job summary so the distinction is visible in review rather than implied.

The ask

Both typecheck and the new workflow have been sitting at action_required on this repo since 18:47 UTC — every run is 0s, nothing has executed upstream. Fork PRs from unaffiliated accounts need a maintainer to approve workflow runs.

Could someone approve the runs on this PR? That's the only thing between this and a reviewable green PR — the code side is done and passing. Happy to re-push if you'd prefer the workflow scoped differently or dropped entirely in favour of the existing typecheck job.
