Xray guidance

Inherit Furious/Backends/AGENTS.md and its ancestors; consult Plugins for capability contracts. This scope owns Xray's full JSON preservation, routing/assets/statistics, and protocol/transport/TLS projections.

Full-document preservation

• The complete Xray JSON document is authoritative. Protocol, transport, TLS, local-endpoint, logging, routing, and TUN editors are partial projections; preserve unrelated inbounds/outbounds, extensions, unknown security/transport data, and unrepresented siblings.
• Loading is observational except for narrow tested compatibility migrations. Legacy transport aliases such as http, gun, and mkcp may map to their supported current representation, but do not expand this into general normalization of unknown future values.
• URI codecs round-trip only their supported projection without erasing the source document. Keep Shadowsocks plugin metadata and SOCKS/VMess/VLESS/Trojan semantics distinct; malformed input returns controlled validation rather than a plausible different profile.

Runtime-specific capabilities

• Logging paths, selected routing, statistics API, local test endpoints, and TUN are prepared on an independent runtime copy. Managed native TUN replaces runtime TUN inbounds; disabled management preserves explicit valid or malformed TUN and suppresses tun2socks. Proxy/download preparation replaces inbounds with its test surface. Verify the prepared document rather than assuming proxyModeOnly alone removes user TUN from every factory input.
• Xray owns routing profiles/options, geo assets, API statistics, and the XRAY_LOCATION_ASSET environment contract. Action providers retain reusable routing/asset windows through the created action owner and create transient settings dialogs per request; the capability registry does not become a transient-window owner.
• Runtime asset updates stage bytes and digest verification before atomic replacement. Failure preserves the prior usable file. Network reply and checksum worker have separate lifetimes: cancellation/shutdown must suppress late hash publication as well as abort requests. The plugin capability owns its lazy updater through shutdown. Deploy.py --download has a separate integrity contract; shared filenames do not make the mechanisms equivalent.
• Routing selection IDs, user routing documents, and translated built-in labels are different contracts. Preserve custom document content and named-profile identity while composing runtime routing/API statistics. Trace the selected repository routing document separately from the connection's own routing branch; neither may be mutated as a side effect of preparing a launch.
• Routing-rule row moves mutate the live profile's rule list in matching order, with Qt move notifications preserving selection. Internal drag-and-drop, the Move menu, and list-scoped Ctrl+Up/Ctrl+Down shortcuts use this same model mutation and preserve selected-row order. Pending rule editors/confirmations use persistent indexes in that exact model: moves preserve their targets, while removal/reset can invalidate them and must suppress write-back. Persistent indexes are not identities across model replacement. Verify this through tests/test_ui_behavior.py and repository/runtime order round trips. Rule-editing confirmations share the transient rules dialog as their Qt owner on every platform, so owner destruction also ends pending confirmation callbacks.
• Statistics preparation is optional and may leave a valid runtime without a statistics target. Preserve that distinction from connection failure; later sampling uses the target captured for this runtime, not newly edited settings or an assumption based solely on the backend name. configureXrayStats() merges the required API service and counter policy into the runtime copy, preserving unrelated valid API/policy fields. Do not replace a user's entire API or policy branch merely to enable counters; test both the merged launch and unchanged stored document.
• Verify full-document and URI preservation, aliases and unknown values, runtime-copy isolation for routing/log/TUN/tests, multiple TUN inbounds, asset integrity/failure, statistics and process cleanup, compiled-safe UI callbacks, and repeated editor/window destruction. Use tests/test_xray_asset_download.py, tests/test_native_tun_semantics.py, and tests/test_backend_editor_contract.py.
