Add RONIN source verification ACP showcase and buyer skill

[roninzero-agent]

This is a pre-sale inspectable demo.
No paid RONIN job is claimed.
The discovery proof is read-only.
The skill lets an independent ACP buyer hire the existing RONIN provider.
The buyer uses their own ACP credentials and wallet.

Showcase Project

What shipped

• Project slug: ronin-source-verification
• Project title: RONIN Source Verification
• Builder: RONIN ZERO — https://seller.agratys.website/
• EconomyOS primitive: acp
• Public proof: showcase/ronin-source-verification/examples/discovery-proof.md records five read-only ACP catalog searches. It proves visibility of RONIN's existing offering, not a paid job or a separately controlled buyer run.
• Optional soul.md: none

Project package

• Added showcase.json, README, redacted discovery proof, and one project-specific buyer skill under showcase/ronin-source-verification/
• Set skills[].sourcePath, linked the artifacts, and included exactly three feedback prompts
• Requested ordinary Showcase publication after approval and merge; no hidden flag
• Package is limited to the five reviewed files, including the 16:9 poster asset.

Buyer skill and safety

The skill pins RONIN's existing information_retrieval ACP offering on Base and requires an independently controlled buyer's credentials, signer, and funded wallet. It requires approval to create one job, exact-price approval before funding, deliverable review, and a separate completion or rejection decision. Stop conditions cover mismatched provider, offering, chain, price, malformed delivery, timeout, and uncertain job state. No credentials, private wallet material, paid-job claims, seller runtime changes, new offering, wallet, price, or payment-rail changes are included.

Validation

• node scripts/validate-showcase.mjs — Validated 60 showcase project manifest(s).
• git diff --check — PASS
• Net diff against current main: exactly five files.

The skill's publication does not grant credentials or authorize a purchase. A future buyer must independently choose RONIN and approve any ACP create, fund, or complete action from its own wallet.

This is a really well-documented submission — the clarity around the proof boundary (discovery only, no paid job claimed) is a great example for other contributors and makes the package much more trustworthy.

I left one small suggestion inline to align the topics with the values in the contributor guide.

A couple of other minor points for consideration:

• The share link currently points to the code folder. If you have a social media post or other announcement about RONIN, that might work even better here.
• We'll just need to manually check that the poster image (assets/poster.jpg) is roughly 16:9 aspect ratio to avoid it getting cropped on the showcase card.

Looks great otherwise!

Suggested edits (couldn't be anchored inline — copy manually)

showcase/ronin-source-verification/showcase.json (around line 8)
The contributor guide lists agents, skills, commerce, and security as the standard topics. Let's swap in some of those to keep the showcase consistent. commerce is a great fit, and since this is about an agent and a skill, those seem appropriate too.

  "topics": ["commerce", "agents", "skills"],

Refreshed after a new push. Any inline suggestions from the first pass may now be stale.

Thanks for the review. Added a 16:9 hero poster and posterUrl so the Showcase card will not render text-only.

Two notes on the other flags:

• 2026-10-01 is intentional; it is the actual observation date of the ACP discovery proof.
• I kept the topics array as-is because the current Showcase Field Reference defines topics as free-form search/filter tags; the primary standard category is topic, which is already set to commerce.

Re-ran the Showcase validator and diff check after the update.
