 - UCXLog-compatible QSO packets and Win-Test `ADDQSO` packets are converted into one validated external-QSO state. Logger-specific numeric, metre and centimetre values and Win-Test band IDs are normalised once; the resolved band is then the sole source for per-band Worked and worked-grid state.
 - A missing or unknown logger band sets only the global Worked state. Worked-grid state requires both a recognised project band and a valid locator; no band or locator is inferred. Packets without a usable callsign are discarded without terminating the listener.
 - External logger threads do not read or mutate the user-list mirror. `ChatController` applies global and per-band Worked state to every active variant of the base callsign on the user-interface thread, through `UiDispatcher`, before evaluating a band-upgrade notice.
+- Explicit **Mark as worked** context actions construct the same validated `ExternalLoggedQso` state and use the same controller/database path as logger `contactinfo` handling. The operation is additive and idempotent; it does not provide an Unwork action or create a parallel UI-only store.
 - The established Win-Test handling for 24, 47 and 76 GHz remains unchanged. Their Worked flags are retained, while only frequencies represented by the project `Band` model can create worked-grid state.

 - Debug file logging reports Station Map refreshes only when total FX-thread refresh time reaches 100 ms. The diagnostic separates snapshot and render time and includes visible-member and station counts.
 - Station selection preserves the established `/cq callsign` prefill behaviour.
 - `StationSelectionState` is the canonical selection shared by the station table and Further Info panel. Its identity is the complete callsign plus chat category. Explicit actions carry a `StationSelectionSource` and increment a separate scroll-request revision even when the same station is selected again; roster reconciliation replaces the selected instance without moving the table.
+- Recent-join state is transient domain state keyed by complete callsign plus chat category. Only live `UA5`/`UA2` frames can create an entry; the `UA0`/`UE` initial or reconnect snapshot and `UM3` profile updates never do. Duplicate live updates do not renew the timestamp, a leave removes the entry, and a genuine rejoin begins a new ten-minute interval. The local login callsign is excluded. The core `ObservableRoster` is mirrored through `UiDispatcher`; New-joined actions reuse the canonical station selection and scroll request.
 - The station table starts with a case-insensitive ascending callsign sort. A user-selected sort remains authoritative across roster and filter updates. An externally selected filtered station is pinned into the table only; `filteredRows` remains the exact filter result used by the map.
-- PM, Public, QSO-of-the-other, priority, timeline and individual map-marker actions route through the application-level station selector. Directed messages target the sender, except that an outgoing local PM targets its receiver. Public and QSO-of-the-other rows target their sender in the message category.
+- PM, Public, QSO-of-the-other, priority, timeline and individual map-marker actions route through the application-level station selector. Directed messages target the sender, except that an outgoing local PM targets its receiver. Public and QSO-of-the-other rows target their sender in the message category. Direct clicks and context clicks inside the station table select without issuing an automatic scroll request; selections originating in the map, messages, priority, New joined or other station controls issue one even when the identity was already selected.
 - The selected-station message radio mode is independent of station identity and always retains the complete callsign plus chat category. `PM_TO_ME` is the private conversation with the local station plus public traffic from the selected station carrying the structured leading `(LOCALCALL)` address, `PM_TO_OTHER` is private traffic sent by the selected station to other participants, `PUBLIC` is traffic sent by it to `ALL`, and `NOTHING` applies no additional type/receiver restriction. An arbitrary callsign mention in prose is not a structured public address.
 - ON4KST chat parsing records `messageDirectedToCommunity` from the receiver field and `messageDirectedToMe` from either a genuine private receiver or the exact leading public address. The selected-station Compose message mirror is initialized with the main window state, before the first selection callback, and roster changes recompute and push the filtered rows automatically.
-- The map's **Reset filters** action uses the same `StationFilterState.reset()` path as the main filter bar and does not change sort, selection, zoom or viewport. Individual raw-callsign markers retain an already selected category variant; otherwise they use the configured Main category. Spatial clusters zoom and never choose an arbitrary member.
+- The map's **Reset filters** action uses the same `StationFilterState.reset()` path as the main filter bar and does not change sort, selection, zoom, viewport or the display-only Grid-color toggle. Individual raw-callsign markers retain an already selected category variant; otherwise they use the configured Main category. Spatial clusters zoom and never choose an arbitrary member.
+- The user list and map share one station context-menu implementation. A secondary click selects a unique target through `StationSelectionState`; base-call markers or screen clusters containing several full-callsign/category identities first require an explicit target choice. Message snippets reuse the existing send-field action, and the context sked editor owns an isolated draft with the target fixed at opening time.
+- Map markers draw only the display callsign; bands, `B+`, locator and QRG details remain in tooltips. When Grid color is enabled, the canvas draws a black outline and a 30 percent black fill overlay for four-character squares from `WorkedGrossFieldCache.snapshotWorkedGrossFieldsAny()`, independently of visible station markers. The cache is rebuilt from SQLite at startup and is the same any-band state used by **Only new grids**.
 - The AP timeline renders the producer's four candidate lanes in order (two in-beam, two global priority) plus a separate sked lane. Its relative 0–30 minute axis normally uses five-minute ticks and increases the interval when labels would overlap. The vertical message splitter applies pane-specific minimums for the timeline, shortcut row and send row, so older stored divider positions cannot clip these fixed-height controls; stored positions remain the unconstrained baseline.
 - Sending without an explicitly selected send category preserves the established Main-category fallback unless explicitly changed.
-- The lower selected-station panel is vertically scrollable. Its message table has a finite, independently scrollable height so Compose never measures a `LazyColumn` with unbounded vertical constraints and every action remains reachable in a short splitter pane. Empty `DataTableView` instances retain their header and border and show an explicit empty-state label. Header metadata and message filters use width-aware flow layouts; the NOT-QRV and sked groups switch between a row and a column from the panel's actual Compose constraint, without duplicating their domain state.
+- The lower selected-station panel contains a vertical two-pane `SplitterPane`: the upper pane owns the independently scrollable message table, while the lower pane scrolls NOT-QRV and Sked above a pinned lookup group. The lower pane reserves 160 dp before stored divider positions are applied, so normal small-window layouts retain direct access to lookup actions; impossible smaller layouts keep the action groups scrollable. `GUIselectedCallSignSplitPane_dividerposition` persists this divider through the existing profile-scoped layout autosave. Station or message updates never reset it. Empty `DataTableView` instances retain their header and border and show an explicit empty-state label. Header metadata and message filters use width-aware flow layouts; the NOT-QRV and sked groups switch between a row and a column from the panel's actual Compose constraint, without duplicating their domain state.
 - The selected-station sked picker takes its options exclusively from `MainWindowState.activeBands`, which originates in `BandOpportunityResolver.getEnabledStationBands(...)`. Station QRG and name evidence chooses the initial band but must not empty or narrow the operator's locally enabled choices. The detected-band header value is already localized and labelled by its producer, so the Compose panel renders it unchanged.
-- Compact desktop buttons, text fields, choices and checkbox rows share `Density.CONTROL_HEIGHT` at 26 dp and `compactControlTextStyle()`. Material touch-target and component defaults must not reintroduce different visible heights. Compass filter buttons keep a common 28 dp width with reduced horizontal content padding; the send-row QRG fields reserve 96 dp and QTF fields 56 dp so normal contest values remain visible.
