DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Cleared sessions from the v5 store no longer stat the filesystem for a timestamp

Under the hood
Useful1 Signal0
Sessions

Cleared sessions get their date from what was already read instead of touching the disk.

What

When a transcript resolves to no usable leaf and the session was cleared to empty, the loader takes the timestamp from the read result instead of calling stat() on the session file.

Details
  • sessions loaded via the storageV5 backend carry v5Read: { mtimeMs } forward, and that mtime is used for the entry's date, created and modified
  • when the mtime is absent the current time is used
  • this matters where a v5 key has no real file on disk to stat
Evidence

v5Read: { mtimeMs: i.mtimeMs },

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
