Build a realistic conversation snapshot that includes all the nasty 25 // cases the fix needed to handle: scaffolded current-turn user message, 26 // injected guardrail nudge (already pre-filtered by the loop, so absent 27 // from the snapshot the tool receives), a tool_result-plus-text block 28 // message, a system message, and a hostile user message containing XML 29 // tags and "ignore previous instructions". 30 // 31 // 2. Pass it through the tool-level extractor (internal/tools.schedule.go) 32 // via a context-installed snapshot provider, just like schedule_create 33 // does at runtime. 34 // 35 // 3. Persist via schedule.Manager.SaveContext to a tmp dir. 36 // 37 // 4. Read the raw JSON sidecar from disk and print it. 38 // 39 // 5. Load it back via LoadContext. 40 // 41 // 6. Format it through the same escape/wrapper logic the daemon scheduler 42 // uses at fire time (reimplemented inline here to keep the test in the 43 // test package without pulling in the daemon package). 44 // 45 // 7.
