- controlForwardServices: skip offline nodes instead of failing entire operation,
so forward pause/resume/delete works when some entry nodes are offline
- onNodeOnline: always sync forward state on node reconnect (not just post-upgrade),
so forwards that changed status while a node was offline get synced
- add ListForwardIDsByNode repo method to sync all forwards (including paused)
- tunnel edit UI: allow deselecting already-selected offline nodes in
entry/chain/exit selectors, matching the backend's existing tolerance
- KCP: switch from fast3 to fast2 mode, enable FEC (10/3), enable
congestion control (nc=0) for automatic rate adaptation
- go-gost/x: support kcp.nc metadata to override mode-initialized
NoCongestion value in dialer and listener Init()
- Diagnosis: add udpPingViaRemoteNode, fix pingViaRemoteNode to
dispatch based on protocol, add Protocol field to federation
diagnose request structs
- Pass tunnel protocol through diagnosis work items
- Support protocol-specific ping (TCP/UDP/KCP) via remote nodes
- Add KCP probe support in websocket_reporter for chain hop testing
- Normalize whitespace in error messages to handle collapsed variants (e.g., 'address alreadyin use')
- Delete all forward service name variants (_tcp, _udp, base) during cleanup instead of stopping after first success
- Add comprehensive test coverage for edge cases
* fix: tolerate service not found during forward deletion
- Refactor deleteForwardServicesOnNode to handle not-found errors gracefully
- Extract deleteForwardServiceCandidates helper for reuse
- Add tests for not-found tolerance scenarios
- Ensures compatibility with legacy node versions
Entire-Checkpoint: a3bacf836c57
* fix: add forward port occupancy validation and runtime residual cleanup
- Add forward port occupancy validation on create/update paths
- Extend self-occupy recovery to clean residual candidate service names
- Add regression tests for address-in-use recovery with legacy runtime residue
Fixes port conflict issues when upgrading from 2.1.6 to later versions

When upgrading from older versions, service names changed from
placeholder IDs (forward_user_0) to real user_tunnel IDs, causing
service not found errors during control operations.
- Add fallback cleanup+rebuild logic on UpdateService when service
not found during the upgrade transition period.
- Add self-healing retry on Pause/Resume when all variants are missing.
- Refactor controlForwardServicesOnNode to support unit testing.
- Add tests for shouldSelfHealForwardServiceControl and
controlForwardServiceCommand helper functions.
Entire-Checkpoint: a7f0c3175d06
- Move user tunnel resolution before building service base name
- Add buildForwardServiceBaseWithResolvedUserTunnel helper
- Ensure service names carry the actual user_tunnel ID instead of 0

When a forward service is updated with a bind IP that doesn't exist on the
host network interfaces, the system now automatically falls back to the
default bind address (listening on all interfaces) instead of failing.
- Added syncForwardServicesWithWarnings to collect fallback warnings
- Implemented fallbackForwardPortToDefaultBind for graceful degradation
- Added UpdateForwardPortBindIP repository method to persist fallback
- Enhanced error detection for 'cannot assign requested address' errors
- Frontend displays warning toasts when fallback occurs
- Added comprehensive unit tests for new error detection functions
When UpdateService encounters bind address conflicts (port already in use),
the handler now automatically deletes existing forward services and retries
the AddService operation. This resolves issues where a forward's own stale
listener prevents the update.
- Add isBindAddressInUseError() to detect port bind conflicts
- Add rebindForwardServiceOnSelfOccupiedPort() for automatic cleanup and retry
- Add HasOtherForwardOnNodePort() repository method to verify port ownership
- Add unit tests for bind conflict detection
- Pass connectIp through resolveChainProbeTarget in diagnosis stream start items
- Pass connectIp in appendChainHopDiagnosis for full chain probes
- Reconstruct tunnel state with connectIp field preserved
- Fix forward service config when bindIP already contains port
- Add contract tests for connectIp diagnosis scenarios
- Add unit test for bindIP with port in buildForwardServiceConfigs
- Update AGENTS.md with plan document rules
Entire-Checkpoint: 35a2e61c2431
- Add extra_ips field to nodes for multi-IP servers
- Add connect_ip field to chain_tunnel for specifying connection address
- Add in_ip field to forward_port for specifying listen address
- Frontend: add UI controls for extra IPs on node form
- Frontend: add connect IP input for tunnel chain nodes
- Frontend: add listen IP input for forward form
- Backend: resolve forward ingress with custom listen IP priority

* fix(diagnosis): avoid result channel deadlock in progress stream
Close the diagnosis result channel asynchronously after workers complete so progress can stream without blocking, and improve tunnel card type chip contrast for clearer protocol distinction.
* feat(diagnosis): stream pending items and render in-progress states
Pre-populate diagnosis stream with pending targets so tunnel and forward dialogs can show per-item diagnosing status immediately. Update result typing and UI states to distinguish in-progress, success, and failure rows/cards consistently.
- Add SSE streaming endpoints for tunnel/forward diagnosis with real-time progress
- Increase diagnosis timeout to 2 minutes with context propagation
- Group forwards by tunnel within user groups in UI
- Add nginx SSE proxy configuration for streaming endpoints
- Make SpeedLimit.TunnelID and TunnelName nullable (optional binding)
- Add SpeedID field to Forward model for forward-level rate limiting
- Update ForwardRecord to include SpeedID for control plane
- Update repository methods to handle optional tunnel binding
- Update handlers to accept optional tunnelId in create/update
- Modify control plane to prioritize Forward.SpeedID over UserTunnel speed limit
- Update frontend limit.tsx to support creating speed limits without tunnel binding
- Update TypeScript types for optional tunnelId and new speedId fields
This allows speed limits to be created as reusable rules that can be applied
to either tunnels (via UserTunnel.SpeedID) or individual forwards (via Forward.SpeedID).
* fix(frontend): left-align announcement logo in homepage banner
* fix(frontend): keep multiselect panels floating and preserve summaries
* fix(frontend): rebalance config card header spacing
* fix(frontend): normalize formatting and fix multiselect modal behavior
* fix(frontend): polish batch actions and sharing page guidance
* fix(frontend): switch grouped forward view to full list
* fix(backend): switch diagnosis internet target to bing
* style(frontend): beautify forward group view list display
* style: remove 'x' suffix from traffic ratio input and center config alert
* fix(ui): expand exit node select upwards in modal
* style: fix vertical alignment of logo and title in announcement banner
Forward diagnosis chain-hop probes now inherit the tunnel ipPreference so v6-priority tunnels test IPv6 targets instead of defaulting to IPv4. Add a contract test to lock IPv6 target selection for entry->chain and chain->exit diagnostics.
- Extract database layer into model and repo packages
- Split repository into focused modules (control, federation, flow, groups, mutations)
- Remove monolithic db.go and sqlite/repository.go
- Update handlers to use new repository structure
- Migrate contract tests to new patterns
- Add migration plan documentation
Route diagnosis for shared remote nodes through federation runtime APIs so tunnel and forward diagnostics work across panels, and add contract coverage for single-panel and dual-panel scenarios.
