Module facade 

SettingsFacade - the seam between the settings MCP tools and the config machinery. The production impl (ProdSettingsFacade) reads the document the settings page draws and routes every write through the workspace’s held-write registry; the mock returns preloaded results so the tool tests can assert argument handling and error surfacing without a config.

Structs

ProdSettingsFacade 🔒

ResolveOnDrop 🔒

Settles the held write as abandoned if the awaiting future is dropped before the write is settled - the calling session died mid-wait, or its connection went. The registry’s own teardown sweep covers a session that goes without running this drop; this covers a cancelled call on a live session. Settling twice is a no-op in the registry.

SettingsSetItem 🔒

One key and its new value, as settings__set hands them through.

SettingsValue 🔒

One key’s effective value, with what a caller needs to act on it.

Enums

SettingsError 🔒

Why a settings read or write did not happen, in the words the tool hands the caller.

SettingsWriteOutcome 🔒

What a write did, which is what the agent’s result says.

Traits

SettingsFacade 🔒

The settings tools’ view of the workspace.
