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

lanspread

Peer-to-peer game library sharing for LAN parties. Peers discover each other on the local network via mDNS, exchange library metadata over QUIC, and let users browse and download games from each other. Ships as a Tauri desktop app.

Build / install

Install Rust, Deno, and just first, then bootstrap the project:

just setup

That installs the Tauri CLI with cargo install tauri-cli and installs the Deno/npm dependencies from crates/lanspread-tauri-deno-ts.

Run the desktop app in development mode:

just run

Build without bundling:

just build

Create production bundles:

just bundle

Important just commands

  • just setup - install the Tauri CLI and frontend dependencies.
  • just run - run the Tauri app in dev mode.
  • just build - build the app without bundling.
  • just bundle - create production bundles.
  • just fmt - format Rust, TOML, and the justfile.
  • just clippy - lint the Rust workspace.
  • just test - run workspace tests.
  • just frontend-test - run frontend tests.
  • just peer-cli-build - build the JSONL peer test harness.
  • just peer-cli-image - build the peer harness Docker image.
  • just peer-cli-run NAME - run one peer harness container.
