One campaign invocation drove the control-panel detail workbench for 9h30m of active time across nearly 13 wall-clock hours. Twice the conversation ran out of context and was continued from a compact summary; each time, the persistence engine re-fired the campaign loop and work resumed where the state file said it was — not where anyone's memory did.

By close: 31 subagents spawned, 30 tasks completed, 149 commits, 153 files touched, 3,019 assistant turns, 1,405 tool calls — ending with a plugin version released and delivered to all installed users.

98.8% cache hit rate: $1,061 actual versus $7,764 uncached. The session that wouldn't fit in one context window also wouldn't have fit in one budget without it.
