Read the full README ↗In the project’s own words, excerpted from the README at the reviewed source revision.
Before you install
- PicoRunner on an Apple Silicon Mac; tested with 0.3.14 on macOS 26.6.2.
- Internet access for initial source and dependency download.
- Habits use IndexedDB in the browser profile; clearing browser data removes local records.
- No account or synchronization service is included.
- Upstream is a completed portfolio demo; production PWA/offline claims need separate evidence from a development launch.
- Native discovery runs the development server; the proposed production manifest and managed updates were not tested through PicoRunner.
- Sanity covered adding/completing one habit and persistence; PWA installation and exhaustive offline behavior were not tested.

- source: Pinned root package declares habit-tracker, dev: next dev --webpack; packageManager is absent (null). Exact package and license bytes match the runtime archive.
- source: Pinned license text identifies MIT.
- install: Canonical import completed in 52 seconds at attempt zero without manual source patches. Tracked source remained unchanged; PicoRunner metadata was added.
- launch: PicoRunner selected the root dev script (next dev --webpack) on its assigned local port; this is native discovery, not the proposed production manifest.
- health: Installer readiness checks completed and the browser UI was reachable and reloaded during restart checks. Process-level socket ownership was not independently established in every case.
- smoke: Created PicoRunner test stretch, marked done today, observed one-day streak and1/7days marked. Demo data unchanged.
- restart: PicoRunner Stop/Start followed by page reload retained named habit, checked state, one-day streak and1/7days marked.
- cleanup: stopped via PicoRunner; test habit and managed source retained. No uninstall or synthetic-data deletion is claimed. The linked batch report records the unrelated-app control incident and unexplained existing-port change.
