What
Alongside the new storage handle, key builders were added for mailbox, fileHistory, jobPins, jobDraft, bridgePointer, sessionAliases and a journal variant of transcripts, and the handle is now an explicit argument to settings writes, scheduled task enable and remove, job dispatch and respawn, MCP CLI subcommands, worktree and workflow dialogs, and the daemon's claim and adopt paths.
Evidence
sessionAliases: (e) => ({ namespace: "sessionAliases", projectKey: e })
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
