 ## Backlog / open work
 Open work lives in **Gitea issues** on `gitea.dohertylan.com/dohertj2/lmxopcua` (`tea issues list --repo dohertj2/lmxopcua`) — they are the single system of record for status.
 The markdown backlogs — `deferment.md`, `docs/v3/twincat-backlog.md`, `archreview/plans/STATUS.md`, `archreview/plans/INTEGRATION-SWEEP-STATUS.md`, the `docs/reviews/2026-10-21/` reports + `docs/superpowers/plans/2026-10-22-review-remediation.md`, and the known-gaps/follow-ups sections of `docs/drivers/*.md`, `docs/ScriptEditor.md`, `docs/Uns.md`, `docs/security.md`, `docs/VirtualTags.md` — are historical/design records carrying `→ #N` pointers (2026-11-06 sweep, label `migrated`, #749–#759). Do not track status in them.
 File every new follow-up, deferral or review finding as an issue with the family labels `type:{bug,feature,followup,review-finding,deploy-gate,debt,docs,test,infra}`, `priority:p0..p3`, plus `blocked` / `cross-repo` where they apply.
 Reference issues from plans and docs as `#N` (cross-repo: `mxaccessgw#N`).

The timeout bounds wall-clock but not allocation; a `new byte[int.MaxValue]`-style allocation or a growing collection in a loop can OOM the whole in-process server before the 250 ms timeout fires.
