Document that read permission expiry and source deletion do not erase
text already copied into the destination conversation, and that reads
follow the source's current visible history. Truncated results now tell
the agent to acknowledge the omission and ask for the missing material
before claiming every requirement is covered.
Pages were filled to 20,000 text characters by cutting the last message
that did not fit, and that suffix could never be paged back. They could
also exceed the default 12,000-character tool-output budget, which
externalized the page to a file. Pages are now sized by their serialized
length against the read_conversation tool-output budget; a message that
does not fit starts the next page intact, so only a message over 4,000
characters (or one whose escaped JSON alone exceeds the budget) is cut.
