Showcase: Aria Vanguard ZHC — live ACP provider on Base (Spark delivery)

[GoldenFarFR]

Showcase: Aria Vanguard ZHC — reopened as infrastructure blocker tracker

Slug: aria-vanguard-zhc
Builder: GoldenFarFR
Agent: Aria Vanguard ZHC — 019f0522-b57b-7e8e-a70a-aab2070e070e
Hire: app.virtuals.io/acp/agents/019f0522-b57b-7e8e-a70a-aab2070e070e

Status (2026-07-04)

Item	State
Showcase package + validate-showcase.mjs	Pass
Live offerings (acp offering list)	Pass (3 offerings)
Provider automation (browse / jobs / events / submit)	Blocked — HTTP 500 Privy/Alchemy path
Escrow job receipt (gate S2)	Pending infra fix

This PR is reopened to track a Virtuals-side blocker, not to request merge before proof. We will mark ready for review once provider submit succeeds and we attach a funded job id.

Evidence (fresh)

See showcase/aria-vanguard-zhc/examples/api-500-blocker-evidence.md on branch showcase/aria-vanguard-zhc.

Summary:

• acp browse → Server error 500 (viem 2.54.3)
• acp job list → same
• acp events listen --legacy → connects, crashes on privyAlchemyEvmProviderAdapter.signTypedData with 500
• acp offering list → OK (marketplace data live)

CLI: @virtuals-protocol/acp-cli 1.0.24, Node v24.16.0, Base chain 8453.

What we need from reviewers / Virtuals ops

1. Is this a known incident on your Privy/Alchemy signer path?
2. ETA or workaround so providers can sign and submit again?
3. Should infra fixes be tracked in a separate issue linked here?

Package contents (unchanged)

Live ACP provider on Base selling analyse_lite_x1 (and related offerings). Backed by ariavanguardzhc.com and GoldenFarFR/ARIA (acp_email_watch degraded mode until submit works).

Validation

node scripts/validate-showcase.mjs
# Validated 12 showcase project manifest(s).

Merge criteria (builder)

We will request merge only after:

• Provider submit smoke test passes (no 500 on signTypedData path)
• ≥1 funded escrow job receipt with public job id (gate S2)
• validate-showcase.mjs still exit 0

Redaction

No operator secrets, vault paths, or deploy scripts.

Reopening as infrastructure blocker tracker (not a merge-ready showcase yet).

Fresh repro 2026-07-04 on @virtuals-protocol/acp-cli 1.0.24 / Node v24.16.0, agent 019f0522-b57b-7e8e-a70a-aab2070e070e, Base 8453:

Surface	Result
acp offering list	OK (3 live offerings)
acp browse	Server error 500 (viem 2.54.3)
acp job list	same 500
acp events listen --legacy	socket connects → 500 in privyAlchemyEvmProviderAdapter.signTypedData

Evidence committed: api-500-blocker-evidence.md (GoldenFarFR/acp-cli-demos@showcase/aria-vanguard-zhc, def04fc).

Impact: we cannot auto-fulfill funded jobs or attach an escrow receipt until provider sign/submit works. Showcase schema validates (node scripts/validate-showcase.mjs → 12 manifests OK).

Asks:

1. Known incident on Privy/Alchemy signer for this agent wallet?
2. ETA or workaround for provider submit?
3. Prefer fixing under this PR or a linked infra issue?

We will append a funded job receipt and request merge once smoke tests pass. Thanks.
