DIEM Agent Workers v0.6.0

DIEM Agent Workers v0.6.0

This release makes the Base mainnet storefront privacy-first and easier for software agents to discover.

Privacy-safe durable metrics

• Adds atomic lifetime aggregate counters backed by Upstash Redis.
• Publishes reliability, coarse failure, fixed latency-bucket, settlement, revenue, and DIEM counters at GET /v1/stats.
• The durable metrics API cannot accept prompts, outputs, payer addresses, transaction hashes, IP addresses, user agents, request identifiers, or timestamps.
• Removes the application-generated timestamp from structured runtime telemetry; Vercel platform logs remain subject to Vercel's own retention.
• Keeps metrics fail-open and latency-bounded so an observability outage cannot alter worker or payment responses.

Production payments now require AGGREGATE_METRICS_MODE=enabled. The checked-in default remains off, and the mode reuses the existing Upstash credentials.

Agent discovery

• Upgrades every worker to the full x402 route format with an explicit public resource URL.
• Publishes DIEM Agent Workers as the Bazaar service name.
• Adds five bounded topical tags per worker, including private-ai and x402.
• Adds a stable public service icon at GET /icon.svg.
• Links aggregate stats from the root document, catalog, OpenAPI, and llms.txt.

Safety posture

• Keeps input validation, Venice capacity checks, the 0.25 DIEM daily software budget, and delivery credits ahead of inference or settlement.
• Keeps the Vercel treasury runtime disabled and signer-free.
• Keeps prompts and outputs out of application logs and durable storage.

Acceptance target

After deployment, run one bounded mainnet acceptance call for each remaining worker. A successful paid response proves the complete agent path: discovery, validation, x402 authorization, Venice inference, output validation, Base USDC settlement, and privacy-safe aggregate recording.
