Our fixes so far: 196 pull requests merged by maintainers of 50 open-source repositories (as of 8 November 2026) — see them on GitHub.
- dated-break-check — A GitHub Action that warns in your build before a dated upstream change (an image tag that moves, an API or model that shuts down, a retired runner) hits your repository.
- breakage-calendar-mcp — An MCP server for coding agents: which dated upstream breaks hit this repository or dependency list, and the tested fix. No key, no account.
- what-breaks-next — Each dated break published as a GitHub Release before its date, with a check and a tested fix. Watch → Custom → Releases to follow it.
- agent-mail-gate — A mail gateway for AI agents: screens inbound mail before any model reads it, sends only the exact bytes the owner approved, and stops follow-ups to anyone who replies, opts out or bounces.
- sync-witness — An Obsidian plugin that notices when a sync tool silently removes notes or rolls them back, tells you once, and restores the exact bytes.
- upgrade-xray — See what an npm or PyPI dependency update really changes, computed from the published files without installing them.
- A CI check for breaks that come on a date, not with a commit (November 13)
- Three email jobs we don't give to a model: why agent-mail-gate screens, approves and sends with plain code (November 13)
- accelerate FSDP2 QLoRA: bf16 quant storage alters packed 4-bit weights at world size ≥ 2 (November 8)
- A Brazilian court fined two lawyers for a hidden instruction to its AI. Of three free PDF checkers, one flagged all 12 versions we hid (November 2)
- ECMWF open data now stores rain in steps coarser than 0.1 mm from 24 hours ahead. A 0.1 mm chance of rain moved by 10 points or more at a fifth of uncertain land points (October 29)
