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.
When the remote hydration process (CCR delta sync) appends entries and the session file grows past a threshold, it now automatically requests compaction via requestCompact(). This keeps remote session transcripts from growing unboundedly.
Evidence
Auto-compact trigger (search for "requestCompact")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
