 17  // TestWalkthrough_ScheduleContext is a narrative end-to-end walkthrough of the
 18  // schedule-context feature after the issue #24 fixes. It runs the entire data
 19  // flow end to end without a live LLM, and prints intermediate state so a human
 20  // reviewer can eyeball the actual sidecar JSON and the final wrapper string.
 21  //
 22  // Flow:
 23  //
 24  //  1. 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. Print the final sticky-context string and assert all the invariants
 46  //     the fix promised.
 47  //
 48  // Run with:  go test ./test/ -run TestWalkthrough_ScheduleContext -v
