Claude Code Contextual Memory Virtualisation (CMV)
Git-like versioning for Claude's context window—finally replay work without rebuilding understanding.

Cursor context pinning · Continue persistent sessions
The idea is that contextual memory virtualisation snapshots that context so you can branch from it later. Spend 40 minutes mapping your codebase, snapshot it, then fork into independent sessions for each task, that way they all sharing the same base understanding. When context gets bloated, trim strips the dead weight (raw file contents, base64 blobs) while keeping every message verbatim. 50-70% smaller, nothing lost from my testing.
TLDR; build understanding once, reuse it, trim the bloat.
