 - **Global source layer only** — session-scope source registration (per-session shadowing, ScopedLayers-alike) is designed but not enabled; the ledger tracks the trigger condition (a real per-session source need).
 - **`SlashCandidate.icon` renders as text** — MenuView drops the string into the icon slot verbatim; wiring to the design-system icon enum (iconFile five-variant family) lands when that enum ships.
-- **Overlay SlotMap merge home is split from slot ownership** — the `conversation.input.overlay` merge lives here (sole copy) while the slot's owner semantics (anchor, children declaration, lifecycle) stay with ui-conversation; the dependency direction (ui-conversation → ui-slash) forces the split, so a future dependency reshuffle should revisit it.
