46// Snapshots the pre-mutation state of every file a tool is about to change, so

47// the user can rewind the filesystem (and conversation) back to any earlier

50// A "turn" maps 1:1 to a user message. The client calls beginTurn() before the

51// agent runs, the loop records file snapshots as mutating tools fire, and

53// back to the state it had just BEFORE that turn ran.

54//

55// Persistence: turns are written to ~/.nexrall/checkpoints/<key>/ on commit,

56// where <key> hashes workDir + an optional session scope. A reload of the CLI

57// or the VS Code window therefore no longer wipes rewind history — resuming

58// the same session in the same directory restores the full checkpoint list.

60// Bash awareness: file snapshots can only cover tool-driven edits. Shell

61// commands (sed -i, git checkout, codemods…) mutate files invisibly. The loop
