Mar 1, 2026

March 2026 was a major step in hardening Pay with AI3 credits and expanding visibility across the product. Delivered a purchasable credits data model and four authenticated API endpoints, enabling purchased credits to be tracked, consumed, and surfaced in UI and admin workflows. Implemented OVER_CAP handling, idempotency guards, startup recovery for pending on-chain intents, and pre-flight credit checks to prevent wasted uploads, significantly reducing retry cycles and financial risk. Optimized economics data retrieval with SQL aggregates and introduced env-driven expiry configuration to support dynamic operator settings. Improved frontend UX with real-time credit summaries, expiry banners, and admin dashboards for monitoring credit health.

February 2026 — autonomys/auto-drive: Delivered stability, performance, and resilience improvements across price querying, memory management, error handling, and deployment hygiene. Implemented a singleton Polkadot API for price lookups with automatic reset on disconnect to prevent WebSocket/WASM leaks; added recovery on initial connection failure; improved error diagnostics for decryption failures; stabilized memory usage by shrinking the default in-memory download cache (1GB) with configurable max size; ensured graceful shutdown and resource cleanup for frontend workers to prevent leaks; optimized CID lookups with a Set for O(1) performance in processNodeArchived; and improved code clarity with targeted refactors. Core contributions reduce runtime memory pressure, improve fault tolerance, and enable safer containerized deployments through clean shutdowns.

January 2026 — Autonomys monthly summary for core delivery and platform hygiene across repositories. Focused on securing large-file workflows, elevating admin visibility, improving accessibility, stabilizing UI/admin interactions, and tightening tooling hygiene to support reproducible builds and clean repos. Key deliverables include a secure large-file downloads feature with size-based routing and server-side authorization, frontend login gating, session management, and enhanced error handling; an Admin Dashboard that surfaces uploads/download statistics and organization details via GraphQL queries; and accessibility improvements by properly associating date input labels with their fields. In parallel, we fixed critical UI stability issues in the download flow and ensured admin data is cleared when navigating between organizations. Finally, we strengthened repo hygiene and tooling to prevent tool-version drift and improve build reproducibility. Business value: reduced security risk and user friction for large downloads, increased operational insight for admins, improved accessibility compliance, more stable user experience for admin flows, and cleaner, more reproducible development environments.
