The suite's fixtures had drifted from the shared GLAuth config, so a green run proved nothing about the service-account bind: the only success-path test used admin/admin123, but the directory's admin carries the standard dev password, and the "not an admin" test used a readonly user that does not exist there at all -- it passed via the user-not-found branch rather than the group-missing branch it names. Realign to real users from scadaproj/infra/glauth/config.toml: admin/password (othergroups include GwAdmin, gid 5610) for the success path, and gw-viewer/password (GwReader only, gid 5611) for the bind-succeeds-but-no-role path. Both are published dev credentials documented in glauth.md, not secrets. The gw-viewer test drops its old no-leak assertion on the credential literal: the real password is the word "password", which legitimately occurs in the generic denial text, so the check would fail for the wrong reason. The no-leak property is still covered with a distinctive literal by the wrong-password test. In its place the test now asserts the property this fixture is uniquely able to prove -- an authorization failure must be reported with the same message as an authentication failure, so it cannot be used to enumerate valid accounts. appsettings ships Server=localhost, so document the MxGateway__Ldap__Server override the suite needs to reach the shared GLAuth alongside the existing MXGATEWAY_RUN_LIVE_LDAP_TESTS and ServiceAccountPassword variables. Verified live: Failed: 0, Passed: 5 against 10.100.0.35:3893.

# 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 so the next review cycle can triage them. None blocks the 2026-07-12 cycle, which is complete. Rows struck through have since been fixed ahead of that cycle; the original finding text is kept so the triage record stays readable.
|
|
|
|
| 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. |
|
|
| ~~NEXT-06~~ | Testing / live LDAP | Medium | **Resolved 2026-08-07** — fixtures realigned to the shared directory (`admin`/`password` for the GwAdmin success path, `gw-viewer`/`password` for the bind-succeeds-but-no-role path); verified `Failed: 0, Passed: 5` live against the shared GLAuth at `10.100.0.35:3893`, so the success-path assertion (GwAdmin group claim + Admin role claim) now fails if the service-account credential is wrong. Original finding: `DashboardLdapLiveTests` fixtures have drifted from the shared GLAuth directory, leaving the suite with **no positive-proof coverage of the service-account bind**. Its only success-path test, `AuthenticateAsync_AdminInGwAdminGroup_Succeeds`, binds `admin`/`admin123`, but the directory's `admin` user carries the standard dev password (`scadaproj/infra/glauth/config.toml`), so that assertion cannot pass. `AuthenticateAsync_ReadOnlyUserMissingGwAdminGroup_Fails` binds fixture user `readonly`, which **does not exist** in the GLAuth config at all — it passes for the wrong reason (user-not-found rather than the group-missing branch it names; the `readonly` name is in fact barred by the README's user/group case-collision rule). The three remaining tests are negative assertions that pass whether or not the service account can bind. Net effect: a green `DashboardLdapLiveTests` run proves nothing about the bind credential — surfaced during SEC-36, where the suite was considered as a substitute for the deferred dashboard-login check and rejected. Fix: realign the fixtures to real directory users (e.g. `multi-role`/`gw-viewer`) or add the missing users to the GLAuth config, and add one test that fails when the service-account credential is wrong. |

|
| NEXT-07 | Deployment / windev | High | The `10.100.0.48` (windev) gateway deployment is **stale and crash-looping**, and has been since at least 2026-08-06 (~10k Hosting-failed events/day). The deployed Server binary dates to 2026-06-25 and predates the auth-DB migration of 2026-07-15: it opens a schema-version-3 `gateway-auth.db` that it supports only at version 2 and aborts at startup, so the `MxAccessGw` service never reaches a listening state. Not a code defect in the current tree — a deploy-drift/operations gap — but it means the repo's only deployed host has been dark for over a day and any host-level verification (including SEC-36's dashboard-login check) is blocked until it is repaired. Fix: deploy a current Server build to windev, or restore/downgrade the auth DB to schema 2 if the old binary must stand. Worth asking separately why a service in a permanent restart loop raised no alert. Discovered during SEC-36. |

## 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.**~~ **Executed 2026-08-07**: the `serviceaccount` `passsha256` was replaced in `scadaproj/infra/glauth/config.toml` (commit `aada53b`) and the shared GLAuth recreated on `10.100.0.35`, so the literal recoverable from this repo's history no longer binds `dc=zb,dc=local`. The new value lives only in the GLAuth hash, windev's NSSM environment, and dev user-secrets. `wonder-app-vd03` was out of scope (it binds a different, `dc=scadalink`/`dc=scadabridge` directory). **Caveat:** windev's dashboard `/login` verification is deferred — that host's gateway is crash-looping on the unrelated stale-deployment fault filed as NEXT-07 — so the bind was verified directly by `ldapsearch` as `cn=serviceaccount,dc=zb,dc=local` instead. SEC-36 is now fully `Done`.
|
|
- ~~**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.~~ **Executed 2026-08-07**: `gitea-runner-2` (id 5, capacity 2) is online on `10.100.0.35` via the `/opt/gitea` compose stack, same `container.network: traefik`, token from a `0600` file mount; the existing runner (id 1, capacity 4) was untouched. Concurrency verified — jobs from three runs ran simultaneously across both runners, and a `gitea-runner-2` job cloned successfully from `http://gitea:3000`. TST-30 is now fully `Done`.
|
|
- **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.
