Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Browser storage ## Purpose Choose the appropriate client storage solution based on data size, security requirements, and lifecycle. ## Procedure 1. First determine the data sensitivity, volume, life cycle, whether it needs to be spread across tabs, and whether it needs to be sent with the request. 2. Use localStorage for a small amount of non-sensitive preferences; use sessionStorage for tab-level temporary data; use IndexedDB for large amounts of structured data or offline caching; prioritize httpOnly cookies for authentication status. 3. Encapsulate unified key prefix, JSON parse/stringify, exception handling, expiration cleanup and quota protection. 4. Sensitive data is processed according to security rules, and plain text tokens, passwords, and credit card information are not put into storage that can be read by JS. 5. Review privacy mode, storage quotas, sanitization policies, and cross-browser compatibility. ## Detailed reference Load [references/storage-patterns.md](references/storage-patterns.md) when it comes to storage selection tables, localStorage/sessionStorage wrappers, IndexedDB examples, cookie helpers, and sensitive data rules. ## Constraints …

How to install
mdr add bovinphang/frontend-craft/fec-browser-storage@sha256:417057ad84c41d42The line at the top of this page pins the label git:20260611.9d7f5e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
