A session gets heavy.
The longer a session runs, the more of its context is old turns — until the agent compacts them into a summary you didn't write.More and more of its context is old turns — until the agent compacts them into a summary you didn't write.Old turns pile up — then get compacted into a summary you didn't write.
Same session. Lighter.
srcprism compacts the session early, in place, and keeps the whole record.
