Lab 4, step 4: the regression release. This removes the prompt cache breakpoint on the Slack agent system prompt, so every model call after the first reads zero cached input tokens.

Merging this is the step that ships the regression. The release tagged from main after this merge is the one the "Cache misses on model calls" monitor catches, and the one the Cursor automation "Sentry issue to fix PR" repairs with a pull request back to main.

Created with Claude Code

Lab 4 regression release. Every model call now reads zero cached tokens.
