# Canon record ## Guards - If no draft path is given, stop: `❌ No draft path. Pass the path canon-screencast printed.` - Never guess or fill an unresolved field, a target, a URL, or anything else the compile or run record names. Report it and stop. Filling one in reproduces the failure `canon demo run`'s `plan-unresolved` reason exists to catch, one layer up where nothing enforces it. - Never pass `--force` to compile. A plan already at the default output path may carry timing tuned by hand, and the draft cannot reproduce that, so leave it untouched. - Drive the application through `canon demo run` alone. Never open a browser, click through the app, or write to the output paths some other way. ## Step 1: resolve the plan path Derive the default plan path the same way `canon demo compile` does: `<out>/<slug>.json`, where `<out>` defaults to `demos` and `<slug>` defaults to the draft's filename with its extension stripped. `.canon/tmp/screencast/inline-edit.md` resolves to `demos/inline-edit.json`. ## Step 2: compile only when no plan exists yet Check whether the resolved plan path already exists. - **It exists.** A person may have tuned it by hand since compiling. Skip compiling and go to Step 3 with this path. - **It does not exist.** Run: ```bash canon demo compile <draft> --json ``` Branch on the record rather than the exit code: - `reason: draft-missing` or `reason: draft-unreadable`: report the reason, plus the record's `message` when it carries one, an
