Phase 7 Final Legacy Surface Matrix

Surface	Current owner	New owner	Status	Removal condition	Blocking reason	Future phase
Chat delivery send-result bridge	LegacyChatDeliveryEventBridge	ChatDeliveryEventProjector / IChatDeliveryEventPort	contained	EventBus publishes structured delivery events directly	EventBus schema still carries coarse send-result fields	Phase 8 delivery event schema
Chat delivery action bridge	LegacyChatDeliveryActionBridge	ChatDeliveryActionService	contained	UI submits ChatDeliveryActionRequest to official action sink	Visible message-menu action surface is still compatibility-driven	Phase 8 chat action surface
Team action bridge	TeamActionRuntimeSink	TeamActionRequest / ITeamActionSink	burned-down	legacy bridge name removed from active code; runtime sink owns Team action sends	Team command runtime port is adapter-backed, not controller-owned	closed in Team legacy burn-down
Key verification source	LegacyKeyVerificationSource	KeyVerificationModel / presentation source	contained	Protocol-specific key verification sources are renamed or split	MeshCore/Meshtastic adapters still share compatibility session	Phase 8 key verification adapters
Key verification sink	LegacyKeyVerificationActionSink	KeyVerificationModel / action sink	contained	Protocol-specific action sinks replace legacy naming	Existing adapter still hides protocol-specific mesh APIs	Phase 8 key verification adapters
Chat key verification modal helper	KeyVerificationModalRenderer	Dedicated modal view object	burned-down	Full modal object owns widget lifecycle	Controller still coordinates modal workflow	UX Pack / modal runtime pass
Team rich message row structured payload	MessageRow summary fallback	TeamRichPayloadDisplay / TeamMessageRichPayload	burned-down	MessageRow carries structured Team rich payload fields and renderers consume them	Full card styling can still improve UX but no longer blocks ownership	closed in Team legacy burn-down
Team position picker LVGL renderer	TeamPositionPickerRenderer	Shared picker renderer	burned-down	UX pack-specific picker replaces or formalizes renderer	Current renderer is LVGL-specific	UX Pack picker
Team Page create/pairing/request command handlers	team_page_components.cpp LVGL handlers	TeamPageCreateTeamAction / TeamPagePairingCommandAction / TeamPageRequestKeysAction	burned-down	command actions own create/pairing/request eligibility and runtime orchestration	Page controller still adapts state, notifications, save, and navigation	Team Page controller burn-down
Team Page event effects and navigation	team_page_components.cpp event handlers/nav helpers	TeamPageEventEffectSink / TeamPageFlowController	burned-down	event-effect sink and flow controller own effects/nav decisions	Page controller still renders and applies page transition side effects	Team Page controller burn-down
Team Page LVGL render helpers	team_page_components.cpp render helpers	TeamPageLvglRenderer	burned-down	renderer owns page labels/buttons/lists/member detail/kick confirm/kicked out rendering	Controller still composes renderer input/context/handlers	Team Page controller burn-down
Team Page kick-confirm command handler	team_page_components.cpp LVGL handler	TeamPageKickConfirmAction	burned-down	command action owns Kick/KeyDist/key rotation/status orchestration	Page controller still adapts state, notifications, save, and navigation	Team Page controller burn-down
Hostlink Team shadow state	hostlink_bridge_radio.cpp local runtime Team state	ITeamUiSnapshotStore / ui::team_presence	burned-down	EvTeamState is projected from canonical snapshot after Team shell handles events	Hostlink still owns Hostlink frame enqueue and Team AppData forwarding	Hostlink bridge split
GPS Team overlay page-state read	ESP GPS map reads Team Page globals	TeamMapOverlaySource over ITeamUiSnapshotStore and Team posring	burned-down	ESP GPS map never includes team_state.h, reads g_team_state, or calls team_ui_posring_load_latest directly	GPS marker widgets remain page-local rendering	Phase 8 map overlay renderer
Contacts Team Page state read	Contacts page reads Team Page globals	ContactsTeamSnapshotSource over ITeamUiSnapshotStore	burned-down	Contacts never includes team_state.h or reads/writes g_team_state	Contacts still owns Contacts page UI workflow and composes Team chat/action sinks	Team consumer closeout
Map tile source/path lookup	Platform tile runtime	MapTileResolver / LegacyFilesystemMapTileSource	contained	Dedicated map tile runtime injects source into renderers	Platform tile code still owns loading cadence	Phase 8 map tile runtime
Map visible tile plan	Platform tile runtime	MapTileRenderQueue	contained	Dedicated map runtime computes queue without legacy MapTile records	LVGL tile record compatibility still exists	Phase 8 map tile renderer
ESP decoded LVGL tile cache	LvglDecodedTileCache wrapper	IMapTileDecoderCache boundary	contained	Decoder cache is injected into a dedicated map tile renderer	LVGL image lifetime is platform-specific	Phase 8 map decoder cache
Map overlay current position	Legacy GPS source adapter	LegacyMapOverlaySource / MapOverlayProjector	contained	Renderer consumes MapOverlaySnapshot directly for markers	Existing ESP marker widgets are still page-local	Phase 8 map overlay renderer
Map overlay team positions	Team map projection source	TeamMapOverlaySource / MapOverlayProjector	burned-down	GPS/map/dashboard consumers use TeamMapOverlaySource; only the Team map source seam reads Team posring	Route/tracker/measurement overlays remain separate deferred items	closed in Team consumer closeout
Map route/tracker overlay	ESP route/tracker draw callbacks	Deferred overlay presentation source	explicitly deferred	Route/tracker stores expose presentation sources and renderer consumes overlay snapshot rows	Route/tracker stores are still platform/page-specific	Phase 8 route/tracker overlay
Measurement overlay	LegacyMapPresentationState	Deferred overlay projection	explicitly deferred	Measurement state projects as MeasurementPoint overlay rows	Measurement tool runtime boundary is not split	Phase 8 measurement tool
GPS page refresh cadence	GpsPageRuntimePump	Runtime scheduler / UI refresh sink	contained	Page-local refresh adapters are replaced by GPS presentation refresh model	ESP GPS page workflow remains large compatibility surface	Phase 8 GPS page runtime
GNSS skyplot timer	GNSS page runtime	Deferred GNSS runtime pump	explicitly deferred	GNSS page cadence uses a runtime pump and skyplot renderer consumes snapshots	GNSS skyplot was outside Phase 7 map/GPS final scope	Phase 8 GNSS scheduling
ACK timeout projection	Adapter hook	Delivery event source	explicitly deferred	Unified ACK source emits structured timeout event	Radio/EventBus source remains protocol-specific	Phase 8 delivery telemetry
Key missing/radio failure projection	Delivery mapper	Delivery event source	explicitly deferred	EventBus carries structured failure kind	Current EventBus send-result schema is coarse	Phase 8 delivery telemetry
