The capability's namespace is owned by the seam because it names the capability, not an implementation: a host composes exactly one provider of ctx.bash, so both executor families register the same namespace with their own schema and composition entry without ever colliding, and a settings document carried between platforms keeps resolving on both. Both executors read their config through a source thunk, so a stored change reaches the next command. The constructor checks the schema cannot express become the section validator, refusing a bad value at the write instead of at the next command. pwsh re-resolves its executable only when the declared path changed, so an unrelated settings change never re-probes the filesystem.
