Whose fault: prerequisite · diagnosed
The product is Linux/macOS only (fcntl locking); it refuses to run on this Windows guest with exit code 2.
Recorded blocker / warning
Step: daybook demo --out daybook-demo on Windows
The product is Linux/macOS only (fcntl locking); it refuses to run on this Windows guest with exit code 2.
Safety: No problems traced to this repository code in these checks.
No problems traced to this repository code in these checks.
OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.
A short run cannot establish that code is safe.
Connections show IP addresses; proxies can hide the final hostname.
Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.
windows behavior observation needs an OS-native file/network/process collector; only the static scan ran.
No Linux syscall trace was collected.
Answers recorded for this run
- On Windows the CLI prints an unsupported message and exits with code 2 before running the demo: Real input produced the expected result: Linux and macOS
Source: message and exits with code 2 before importing platform-specific locking code.
Input: daybook demo --out daybook-demo-claim on Windows
Expected: exit code 2 and a message naming Linux and macOS
Command: 'C:\coldpass\workspace\.venv\Scripts\daybook.exe' demo --out daybook-demo-claim-checker-771ef2c64d30429fbda985f1b239be71
Observed: Linux and macOS; Windows is not supported yet
- Exit code 2 is documented for an unsupported platform: Real input produced the expected result: Linux and macOS
Source: | 2 | Unsupported platform or invalid command-line arguments. |
Input: daybook demo --out daybook-demo-table on Windows
Expected: exit code 2 and a message naming Linux and macOS
Command: 'C:\coldpass\workspace\.venv\Scripts\daybook.exe' demo --out daybook-demo-table-checker-6eb67b7c76ac4348808590bba28b6454
Observed: Linux and macOS; Windows is not supported yet
- The demo brief is saved under daybook-demo/state/briefs as Markdown and JSON: Prerequisite missing: the README says Windows is unsupported (locking uses fcntl). On this Windows guest daybook demo refuses to run (exit 2, Linux and macOS message), so no brief is produced. Not testable here.
Source: The brief is printed and saved under `daybook-demo/state/briefs/` as Markdown and
Observed: Prerequisite missing: the README says Windows is unsupported (locking uses fcntl). On this Windows guest daybook demo refuses to run (exit 2, Linux and macOS message), so no brief is produced. Not testable here.
Examples
- Documented offline test suite runs: Prerequisite missing: the README says Windows is unsupported because locking uses fcntl. On this Windows guest, with the README venv at .venv\Scripts\python.exe, the documented command ran and failed at import: 'ModuleNotFoundError: No module named fcntl' (Ran 42 tests, FAILED errors=41, skipped=1). Not run as a passing example; the suite needs Linux/macOS.
Source: README.md: Extensions and development (python -m unittest discover -s tests -q)
Expected: documented command completes successfully
Observed: Prerequisite missing: the README says Windows is unsupported because locking uses fcntl. On this Windows guest, with the README venv at .venv\Scripts\python.exe, the documented command ran and failed at import: 'ModuleNotFoundError: No module named fcntl' (Ran 42 tests, FAILED errors=41, skipped=1). Not run as a passing example; the suite needs Linux/macOS.
- Documented byte-compile check of package and tests: command completed successfully with no output
Source: README.md: Extensions and development
Input: python -m compileall -q second_brain tests
Expected: Silent exit 0
Command: 'C:\coldpass\workspace\.venv\Scripts\python.exe' -m compileall -q second_brain tests
Local or hosted: local
Suggested next step (unverified): Run the quickstart on a Linux or macOS guest (for example Ubuntu with uv installed). Optionally add a Windows-specific locking implementation, or document the platform gate in the README quickstart before testing on Windows.
