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.

Transcripts fall back to a second store when the primary read fails

You'll notice
Useful3 Signal2
Sessions

If the main transcript store fails to read, a second store is tried instead of erroring.

What

Loading a saved transcript no longer fails outright if the primary storage read errors; it retries against a records-based store and reports which source served the data.

Details
  • Size checks now prefer the stored byte count over the length of the buffer in memory.
  • The check for a truncated tail is skipped when the fallback path supplied the data.
Evidence

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