- WorkspaceRegistry.archiveSession no longer wraps persistence-listing
failures as WorkspaceUnknownSessionError: only a definite miss (live
lookup, header index, then a fresh list) maps to session-not-found;
storage faults propagate as internal errors, with a negative test.
- The archived-current sweep moves from the unary path into the
projection: any install path (local echo, another tab's frame, a
reconnect baseline) clears a selection that landed in the archive set.
- An archive set installed while workspace.list is in flight supersedes
the stale baseline's set instead of being rolled back by it.
- The workspace-management e2e anchors the archived row by its session
actions button and asserts the single-stray fixture assumption loudly.
- Drop the stale touchSession rows from the workspace READMEs (the
method was removed with its Agent Note).
