What
- PDF page extraction: when the work is cancelled, it now reports the cancellation instead of calling it an "unknown" error.
- Conversation compacting: new helpers detect when a compacted summary comes back without its block. Compacting shortens a long conversation into a summary.
Why
A cancelled PDF read now shows up as a cancellation rather than a confusing unknown failure.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what happens after a summary without a block is detected.
