Every session, every agent, in one window: who's working, who needs you, and each ask matched to every edit it made. Fully captured, kept on your machine forever.Every session, every agent: who needs you, each ask, every edit. Kept on your machine.

The city is your session. Every building an edit. Every edit traced back to its origin.
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. Every turn is archived byte-exact, a few lines of live state carry the thread, and any earlier turn comes back exactly.The session compacts early and keeps the whole record.
