- Replace syncHost/syncSnapshotPath/… with syncCliTokens: string[] passed verbatim to --sync-cli sync
- Move sync CLI validation from launcher to parseSyncCliTokens (app-side single owner)
- Extract resolveImmersionDbPath to shared db-path.ts importable by both launcher and app
- Delete driver.ts; inline types into libsql-driver.ts and hard-wire openLibsqlSyncDb
- Drop OpenSyncDb injection from mergeSnapshotIntoDb and createDbSnapshot
The engine now executes only inside the app (libsql): subminer sync
rebuilds the equivalent --sync-cli argv and spawns the discovered app
binary with the terminal attached (stdin for ssh prompts, raw NDJSON
stdout, exit-code passthrough). The bun:sqlite driver binding and the
launcher-side engine shims are gone; flow tests moved to
src/core/services/stats-sync/sync-flow.test.ts, ssh tests to src, and
the merge suite now runs through the libsql driver the app ships.
Remote temp dirs are now created and removed by the remote SubMiner
itself (sync --make-temp / --remove-temp, validated against its own
tmpdir) instead of mktemp/rm, and the flow detects the remote shell
(POSIX, cmd, PowerShell) to pick quoting and SubMiner install-location
candidates - %LOCALAPPDATA% app install, launcher shim, or PATH - with
no POSIX PATH prefix on Windows. Remote temp paths are normalized to
forward slashes for scp and the CLI. Verified end-to-end against a
throwaway sshd with the app binary as the resolved remote command.
