• Course authored against the ZCode documentation (zcode.z.ai/docs: desktop-native workspace, Goal Mode objective management and recovery, task lists, file references, remote control from a phone while the desktop remains the runtime) and the shared report-tool core. TASK.md, tests/, scenario/, starter/, solution/ are byte-identical to the Claude Code / Codex course cores — enforced by the core-group check in tools/verify_courses.py.
• Environment for mechanical verification: macOS (arm64), Python 3.13.
• Commands and results:
  • python verify.py starter --expect-failure — exit 0; expected failures reproduced.
  • python verify.py solution — exit 0; 9/9 tests pass.
  • python tools/verify_courses.py — contract satisfied, core identical.
• Not done: any run inside ZCode. No ZCode install or account was used; every ZCode behavior described in the lessons is sourced from official documentation, not observed.

• L01 (EN+ZH) rewritten around the fixed order: get the tool running → install the FlyPython Skill (network access included) → let the agent fetch this course's files via the files endpoint. All "download this folder" wording removed from COURSE.md and lessons.
• The learner's check command across lessons is now the bare python verify.py (FP-820): per-checkpoint status + claim codes, non-zero exit while gated checkpoints are open. solution is no longer presented as a completion standard.
• Tool-specific Skill install and network steps are authored from the same official documentation as the course; not yet exercised inside the tool — the pending live run-through below still stands.

• One full agent-taught run-through inside ZCode ("start lesson 1" through the Lesson 5 checkpoint) on a current build, recording observed deviations from COURSE.md here — including how Goal Mode presented the lesson checkpoints in practice.
• Whether the free tier lasts the whole course is unverified.

(none yet — no live run has happened)
