ddidderr 62cd9306bd feat(peer): journal download file ownership
Track the exact regular files owned by each completed and in-flight peer
download instead of sweeping every non-reserved path after cancellation. Bind
the record to the canonical games directory, publish pending ownership before
payload mutation, and use the final version.ini rename as the recovery commit
point.

Make replacement, cancellation, and startup recovery preserve unknown files
and install state while removing stale or partial downloader-owned bytes. Add a
new-format baseline so legacy discarded sentinels cannot make partially
modified payloads ready, sync payload and journal state in transaction order,
and serialize startup recovery against operation admission.

Document ambiguous legacy target adoption, portable alias transitions, and the
other ownership tradeoffs in the refactor decision log.

Test Plan:
- `just clippy` -- passed
- `just test` -- passed (182 peer-core tests plus the full workspace)
- `just fmt` -- Rust, TOML, and Prettier formatting completed; the command then
  stopped on 40 pre-existing rumdl findings in unrelated Markdown content
- `git diff --cached --check` -- passed

Findings

Open

handleErrorEvent still writes status fields directly

crates/lanspread-tauri-deno-ts/src/hooks/useGames.ts:80-89 — the error handler writes install_status, status_message, status_level, and download_progress from a lifecycle event, which is the same "two sources of truth" pattern that commit 5df82aa ("fix(ui): derive operation status from snapshots") removed everywhere else. That commit explicitly carved out error messages as a preserved side effect, so this is a documented exception rather than a regression — but if we want strict snapshot-is-truth, the error handler should stop writing status fields and let the next snapshot reconcile the card, keeping only the error message overlay (which the snapshot does not carry).

Not blocking. Captured here for a future cleanup pass.

Claude Review Scope Triage

No out-of-scope code smells or issues were identified in Claude's review. All four points were direct follow-up cleanup for the current protocol change and were handled in code.

The previous four findings have landed in code and tests:

  • Download ownership is now journaled before payload mutation. Cancellation and startup recovery remove only exact downloader-owned paths and preserve unknown root files, instead of leaving crashed partial archives or broadly deleting the game root.
  • update_game now uses PeerCommand::FetchLatestFromPeers to skip local manifest serving and fetch fresh peer metadata. Covered by update_fetch_emits_fresh_manifest_from_latest_peer and update_request_skips_local_manifest_even_when_download_exists.
  • Download-to-install handoff no longer relies on OperationGuard::Drop for ordered state transitions. Covered by download_handoff_waits_for_readers_and_auto_installs and the liveness cancellation tests.
  • Library index reads and writes are serialized by LIBRARY_INDEX_LOCK. Covered by concurrent_rescans_preserve_both_index_updates.

Manual install/update/uninstall smoke testing is still a useful release check, but there are no known blocking findings left in this file.
