If messy backfills, one-off prod fixes, and overflowing tickets keep you up, here’s what changed in the last two weeks and what to do next. Vendors and OSS shipped agentic, multi-agent coding features late Dec (Anthropic 2025-12-23; Cursor, Windsurf; AutoGen 0.4 on 2025-12-22; LangGraph 0.2 on 2025-12-21) so LLMs can plan, implement, test, and iterate across repos. On-device moves accelerated (Apple Private Cloud Compute update 2025-12-26; Qualcomm/MediaTek benchmarks mid‐Dec), making private, low-latency assistants practical. Data and migration tooling added LLM helpers (Snowflake Dynamic Tables 2025-12-23; Databricks Delta Live Tables 2025-12-21) but expect humans to own a PDCVR loop (Plan, Do, Check, Verify, Rollback). Database change management and just‐in‐time audited access got product updates (PlanetScale/Neon, Liquibase, Flyway, Teleport, StrongDM in Dec). Action: adopt agentic workflows cautiously, run AI drafts through your PDCVR and PR/audit gates, and prioritize on‐device options for sensitive code.

If your idle on‐chain dollars feel expensive, pay attention: tokenized U.S. Treasuries have crossed USD 10 billion in AUM as of late Nov–early Dec 2025, up from under $1 billion in early 2023 and multi‐billion by late 2024. This piece explains what happened and what to do next for traders, fintech builders, and risk teams. Key drivers: 4–5% short‐dated yields, Treasuries’ risk‐free status, and programmable token formats plus institutional launches from BlackRock, Franklin Templeton, Ondo and Maker. Impact: they’re becoming base collateral in DeFi, creating new arbitrage and NAV‐price trades, and offering dollar‐linked, yield‐bearing rails for payments. Watch custody/legal structures, smart‐contract risk, and liquidity/redemption mechanics. Immediate actions: integrate T‐Bill tokens into collateral and treasury strategies, build RWA‐aware analytics and risk models, and stress‐test on‐chain/off‐chain behavior.
