# Progress

2026-10-23: inspected both legacy copies and empty destination. Verified compiler availability on macOS; Orb Ubuntu amd64 has Rust and networking tools. Established scope and sent optional UI clarification (no preferences). No old files modified.

2026-10-23: created Cargo manifest/config validation and engine contract. TCP engine delegated to one implementer under subagent-driven-development. Canonical ForcAD source verified; found initial-vs-delta event mismatch in legacy client. Orb does not mount the macOS Desktop path directly; stage source under ~/Downloads for Linux runs.

2026-10-23: engine delivered and self-reviewed, 11 tests passed. Added zero-copy-reuse primary buffer path when no replicas are active (no per-read shared-Bytes allocation). Controller, health, state persistence/rollback, auth, API and CLI implemented. Added control-plane tests; integrated run waiting for UI app.js. UI implementation delegated after engine implementer finished. No live game endpoints contacted.

2026-10-23: initial rewrite committed locally as `4b01fb4`; prior checks passed 23 tests on macOS and Orb amd64, Clippy and JS syntax. A real upstream-version Socket.IO fixture passed; a macOS byte-verified loopback benchmark showed measurable proxy overhead. Independent review found five Important issues (see `docs/review.md`); they remain open.

2026-10-23: user rejected the UI redesign and required the original appearance and functionality layout with only small changes. Source comparison confirms two unintended workflow changes: direct custom IP requires creating a team, and quick primary promotion discards the old primary from replicas. Explained these regressions and the unfinished backend review findings. Recorded the correction as binding; no UI restoration implemented yet. Original directories remain references, and the rewrite has not been deployed over them.

2026-10-23: restored literal legacy UI, bundled matching CSS/icon dependencies with licenses, kept former-primary replica and direct custom-IP flows. Added own-team strip, stale snapshot/health indicators, keyboard support and draft preservation. Source CSS parity and matching computed styles checked; browser verified primary/start/robot/custom IP/settings/logout,1MiB exact half-close,390px layout and SSE watchdog/recovery.

2026-10-23: fixed initial R1-R5 plus accept retry, early engine quiesce and absolute heartbeat deadline. Root fresh native35/Orb36 tests passed, native fmt/Clippy and both release builds passed. Real ForcAD library interop passed. Six benchmark runs saved under docs/benchmarks; strict replica byte totals complete, isolate saturation recorded3 explicit replica disconnections on each platform. Final reviewer found R6 transaction cancellation; fix/review in progress.

2026-10-23: R6 resolved with admitted owned transaction worker shared by service/team/automatic changes. Five cancellation regressions, original HTTP red/green and independent re-review accepted. Root fresh final gates: native40/Orb41 tests, native fmt/Clippy, both release builds, ForcAD library interoperability and sample config/JS checks all passed. Final release UI start/primary/replica/robot/custom creation and exact1MiB half-close rechecked. Six final benchmark records committed; isolate disconnections3macOS/4Linux documented explicitly. Prepared git-ignored dist binaries/checksums; no deployment.

2026-10-23 UI follow-up: reproduced off-center modal at(0,0), repaired Bootstrap/native-dialog interaction and header wrapping without redesign. Added local draft/input improvements, team add/rename and configuration help. Fresh40 native/41 Orb tests and release builds pass; browser validates390px layout, CRUD, keyboard invalid IP, restart persistence, stale/recovery and exact256KiB half-close with replica integrity. Live demo migrated from temporary state to ignored data/demo, preserving primaryB/replicaA/enabled; readiness/assets and21504-byte echo verified after restart. See docs/ui-polish-verification.md. Test fixture stopped, live GUI-session job remains running.
