actual_behavior

Spark OS parser defaults pointed compile/capabilities/authority/trace/memory at Linux ~/Desktop under WSL, missing normal Windows Desktop checkouts unless --desktop was manually supplied.

expected_behavior

Under WSL, Spark OS defaults should prefer the existing Windows Desktop path converted to /mnt/c/Users//Desktop while preserving non-WSL ~/Desktop behavior and explicit --desktop overrides.

repro_steps

1. Run Spark CLI under WSL with Spark/operator repos on the Windows Desktop.
2. Run spark os compile --json or parse any spark os <subcommand> without --desktop.
3. Observe the default desktop root points at Linux ~/Desktop rather than /mnt/c/Users//Desktop.

before_after_proof

Before: origin/master sets each Spark OS subcommand default directly to str(Path.home() / "Desktop"), which resolves to Linux /home//Desktop under WSL and misses Windows Desktop checkouts. After: resolve_default_desktop_root() returns /mnt/c/Users/aeyon/Desktop on this WSL host when the Windows Desktop exists; PYTHONPATH=src python3 -m spark_cli.cli os compile --json completed with privacy flags false for raw secrets, logs, conversations, memory evidence, and SQLite row contents. Verification excerpts: running_under_wsl= True; default_desktop= /mnt/c/Users/aeyon/Desktop; 578 passed, 1 skipped, 137 subtests passed in 13.63s; python3 -m compileall src tests passed; git diff --check origin/master...HEAD passed.

tests_or_smoke

Verified locally in /home/aeyo/.spark/tools/spark-cli: PYTHONPATH=src python3 -m pytest tests/test_cli.py -q passed with 578 passed, 1 skipped, 137 subtests; targeted new tests passed; python3 -m compileall src tests passed; git diff --check origin/master...HEAD passed; PYTHONPATH=src python3 -m spark_cli.cli os compile --json completed.

duplicate_notes

Checked the public open spark-cli PR list and searched open PRs for WSL/Desktop/Spark OS wording. Open PRs #519-#528 covered URL parsing, output truncation, env stripping, git summary failures, scoped IPv6, and exception narrowing; no open public PR found for WSL-aware Spark OS desktop defaults.

risk_notes

Low scope: parser default selection only. Non-WSL hosts still use ~/Desktop, WSL falls back to ~/Desktop if Windows Desktop cannot be resolved, and explicit --desktop arguments continue to override the default. No credentials, runtime secrets, registry pin changes, installer publication, or destructive local actions are included.

QA approval packet check

I could not submit a formal GitHub approval from this account because GitHub rejected the review action for this token/account.

QA status: approved from operator-side verification.

Verified:

• Live PR body packet re-fetched and validated: ok=true, packet_valid=true, error_count=0, warning_count=0.
• Local tests: 578 passed, 1 skipped, 137 subtests passed.
• python3 -m compileall src tests passed.
• git diff --check origin/master...HEAD passed.
• spark os compile --json smoke completed with privacy flags clean.

No blocking issues found.
