CommandService.execute appends the log-only pair around every resolved handler — run before invocation, done at settlement, including thrown and aborted handlers (kind:'error'); admission misses log nothing. commandId is minted monotonically per instance; per-session appends serialize through a tail queue over SessionStore.appendOutOfBand (zero-step wrap on an idle log, direct join inside an open turn). The invariant companion now asserts the pairing relation (unique run ids; a done requires a prior in-log run). CommandSource is a minimal merge-extensible map (user variant only). Dependent benches mount SessionStore; TUI/e2e snapshots re-recorded for the executor's durable-append timing and the /status event counts.
