Preserve required UAC elevation for game_setup.cmd, game_start.cmd, and server_start.cmd through a fixed-role elevated launcher worker. The worker reloads and matches embedded catalog authority, verifies the exact script from a no-follow locked handle, resolves System32 cmd.exe, and transfers path locks into the command process.
Setup still waits for completion; game and server return after the verified handoff while their command process retains the locks. Unmanifested, changed, reparse-backed, markerless, and streamed-only scripts fail closed.
Test Plan:
- just test
- just clippy
- just frontend-test
- just build-fixture
- nine Linux-visible authority/parser/digest tests
- Windows-only lock-transfer test added but not run (no Windows target/runtime available)
- git diff --check
Replace address-only trust and pushed peer state with installation identities,
SPKI-pinned QUIC, candidate-only discovery, and bounded responder-owned
protocol-8 pulls. The runtime now owns each network generation and all admitted
work through shutdown.
Add exact bundled content identities, reproducible manifest publishing,
capability-confined downloads, streaming BLAKE3 verification, quarantine and
retry, and crash-recoverable download and install transactions. Ship generated
fixture catalogs and fail closed when production manifests are absent.
The Tauri backend exposes durable sharing policy, redacted identity state, and
attempt-keyed transfer snapshots. Frontend consumption follows in the next
commit. Repository-wide test certificates and protocol-7 paths are removed.
BREAKING CHANGE: peers must use protocol 8 and exact catalog content artifacts;
protocol-7 frames and shared-certificate identities are no longer accepted.
Test Plan:
- `just test` -- passed on the completed stack (708 workspace tests)
- `just clippy` -- passed on the completed stack
- `just build` -- passed with fixture catalogs on the completed stack
- `just catalog-check-production` -- failed closed because the external
production manifest corpus is absent
- `git diff --cached --check` -- passed
