Persisted wallet credits and verified payment tx hashes across gateway restarts, tightened duplicate-payment protection after restarts, made payment-state writes transactional so failed saves do not burn credits or corrupt state, and expanded regression checks to catch stale session pricing drift.
Canonicalized public pricing around proportional credit top-ups, documented whole-credit floor rounding, rejected too-small payments that would mint zero credits, and added anti-regression checks for stale public claims and pricing copy drift.
Unified public messaging around x402 wallet auth, removed unsupported SDK and API-key onboarding claims, synced MCP tool names to the live gateway, removed the analytics stub from the public activation path, and moved status checks to a cached gateway summary.
Added verification status APIs, registry code status checks, admin smoke matrix automation, and state-change tracking for operations audit trails.
Closed auth bypass vectors, enforced admin auth for sensitive endpoints, hardened CORS behavior, and verified push execution paths on-chain.
