+# Candidate Findings for the Next Review Cycle (surfaced during 2026-07-12 remediation)
+
+These were discovered while remediating the 2026-07-12 backlog but were **out of scope** for it — each is either pre-existing, by-design residual, or a new observation. They are recorded here (not fixed) so the next review cycle can triage them. None blocks the 2026-07-12 cycle, which is complete.
+
+| ID (proposed) | Area | Severity (est.) | Summary |
+|---|---|---|---|
+| NEXT-01 | Testing / macOS | Low | Fake-worker/e2e gateway tests fail on macOS under the default `TMPDIR` because the `CoreFxPipe_mxaccess-gateway-{pid}-{sessionId}` path exceeds the 104-char Unix-domain-socket `sun_path` limit under `/var/folders/…/T/`. Workaround today is `TMPDIR=/tmp`. Fix options: shorten the pipe name, or document the `TMPDIR=/tmp` requirement in `docs/GatewayTesting.md`. Surfaced independently by multiple remediation agents. |
+| NEXT-02 | Clients (.NET, Java) | Low | The .NET and Java CLIs render the raw `ReplayGap` sentinel `MxEvent` on `stream-events` instead of a typed gap row — Java text mode prints `0 MX_EVENT_FAMILY_UNSPECIFIED`. Same defect class as CLI-36 (Go) / CLI-35 (Python), which were fixed this cycle; the .NET/Java halves were out of scope. The cross-language smoke matrix now records this divergence honestly. |
+| NEXT-03 | Gateway alarms | Low | `GatewayAlarmMonitor.ApplyReconcile` feed-repair broadcasts (the new acked-delta from GWC-26 **and** the pre-existing Raise/Clear repair) are **at-least-once, not exactly-once**: a periodic reconcile can synthesize a transition whose matching live transition is still buffered in the alarm lease, so both broadcast as indistinguishable duplicates on the alarm feed (StreamAlarms + dashboard hub). Pre-existing (the Raise/Clear repair always had it); GWC-26 documented the at-least-once contract rather than closing the race. Closing it needs reconcile/live serialization or a monotonic dedup marker. |
+| NEXT-04 | Worker frame writer | Low | WRK-22/WRK-25 cancellation path: a frame `Claimed` by a concurrent lock-holder just before its caller's cancellation races in is never awaited by that caller; if the write then faults, `TrySetException` lands on a `Task` nobody observes (unobserved-task-exception). By-design residual, non-crash (no `UnobservedTaskException` handler registered), pre-existing to single-frame WRK-22 and amplified per-batch by WRK-25. Hygiene fix: attach a fault-observing continuation to abandoned/tombstoned frame completions. |
+| NEXT-05 | Worker frame writer | Info | A batch whose remaining frames are tombstoned by cancellation leaves dead `PendingFrame` entries in `_eventFrames`/`_controlFrames` until a future `DequeueNext` pops and skips them. Same pre-existing behavior as single-frame WRK-22, amplified per-batch; in practice heartbeats purge them promptly, so not a real leak. |
+
+## Operator actions still pending (from this cycle's runbooks)
+
+These are **live-infrastructure actions the operator must execute** — the repo-side work is complete and merged:
+
+- **SEC-36** — rotate the dev LDAP service-account credential per `docs/runbooks/SEC-36-ldap-credential-rotation.md` (generate new secret in `scadaproj/infra/glauth`, pre-stage the NSSM env var on deployed hosts, rotate GLAuth on `10.100.0.35`, verify dashboard login). The committed literal is gone from the working tree but remains recoverable from git history until rotation completes — **rotation is the load-bearing half.**
+- **TST-30** — register a second Gitea `act_runner` on `10.100.0.35` per `docs/runbooks/TST-30-second-ci-runner.md` to relieve the single-shared-runner bottleneck.
+- **TST-25 follow-ups** — old **TST-05** (scheduled live-MXAccess smoke) is now covered by the `nightly-windev` job; old **TST-24** (client wire tests in CI) is unblocked by the working Windows tier.
