Summary
After [#445] / [#446] merged into pre-main, CodeRabbit re-reviewed promotion PR [#440] and flagged 5 follow-ups on the fix code itself. All addressed here.
- fs_utils
atomic_write_json — fsync before rename (Major): sync_all() the temp file before the atomic rename, so a crash/power-loss right after the rename can't persist the new directory entry while the data blocks are still buffered (empty/torn file). Hardens all three call sites (settings / analytics / account) at once.
- uninstall —
--purge short-circuit (Major, correctness): nothing_to_do() ignores ~/.meridian, so a --purge whose directory holds only uncatalogued files would print "Nothing to remove" and skip the wholesale rm -rf. Now the human path proceeds to the purge in that case.
- uninstall — honest agent-removal reporting (Major): the human path no longer prints "✓ removed agent" when the plist deletion actually failed (reports ⚠ instead). Documents why
launchctl bootout's exit status stays best-effort in both paths (a not-loaded agent legitimately returns non-zero).
- account
save_account_email — span status (Minor): added err to #[tracing::instrument] so a failure marks the span ERROR.
- uninstall/tests — temp-dir hygiene (Trivial): switched to
tempfile::TempDir so scratch dirs clean up via Drop, including during panic unwinding — no /tmp leak on a failing assertion.
Test plan
cargo test --lib: 437 pass; cargo test --lib uninstall + -p meridian-core fs_utils green
cargo clippy -- -D warnings + cargo fmt --check: clean (root + tray)
Last of the review follow-ups for [#440]. Once this lands on pre-main, [#440]'s diff reflects it.
