Sessions could be archived from the sidebar row menu but never restored:
the registry-global archive set was a one-way display filter with no
inverse RPC and no surface listing its members.
WorkspaceRegistry.unarchiveSession drops one id from archivedSessionIds in
one durable write on the same operation chain as archive, with no
session-existence probe because a removal cannot introduce an unknown
referent. The Workspace controller exposes it as workspace.unarchiveSession
returning the complete archive set, which the existing archived follow
increment already propagates, so no frame type and no persisted field
changes.
The new client package dsh-client-ui-settings-unarchive-sessions owns the
restore surface: one localized settings.section page listing the archive
set joined with loaded session summaries, newest archive first, searchable
by title or workspace, with one Unarchive action per row.
A jump clicked while the Load-earlier pull was in flight fell through the
settle effect's nearest-turn fallback and landed on the wrong row. The
effect now keeps the pending jump (busy pulse stays) while loadingOlder is
true and a retry tick re-issues loadThrough when the pull settles.
Also repins the long-interactions e2e rail block to the outline-rail
semantics (fixed mark pitch, load-and-jump labels) and covers the
loadThrough forwarding paths in apply-inject and the client-runtime stub.
Single RemoteError with a merge-extensible, domain-prefixed code map;
owners throw at the failure point; streams surface marked failures;
clients consume ctx.remote directly with isRemoteFailure as the only
discrimination point and construct no failure instances.
