+Follow-ups recorded here — all closed or narrowed on 2026-08-18 (branch
+`feat/followup-closeout`, plan `docs/plans/2026-08-17-followup-closeout.md`).
+Each bullet states what it said when written, then its closure:
+
+- `IGatewayAlarmService.StreamAsync` / `AlarmFeedMessage` did not carry the truncation
+  signal — live central-feed consumers (lmxopcua, ScadaBridge) could not see snapshot
+  degradation. **Closed 2026-08-18 — shipped.** `AlarmSnapshotStatus` with
+  `snapshot_status = 5` on the feed: gateway-side edge emission plus open-time priming
+  (`fccf753`, `312e072`), rolled out to all five clients (`c748361`, `4d4f443`).
+- "No guard keeps `clients/rust/protos/` in sync with Contracts." **Was stale when
+  written.** `scripts/check-codegen.ps1` Check 3 already existed and already byte-compared
+  by SHA-256 in CI. The real gap was narrower — the sweep ran in one direction only, so a
+  canonical proto with no vendored copy passed. **Closed 2026-08-18** by `711793f`: Check 3
+  now sweeps both directions and a canonical proto missing its vendored copy fails.
+- `EffectiveDashboardConfiguration` (dashboard settings page) didn't display
+  `GroupToTag` / `UntaggedSessionVisibility`, though it showed `GroupToRole`.
+  **Closed 2026-08-18 — shipped** (`094f2ff`; comparer propagation fixed in `ff16c69`).
+- ApiKeysPage's `ConstraintText` neither offered tag input nor listed `DashboardTags`,
+  and since `IsEmpty` counts tags, a tags-only key rendered `-` where a truly
+  unconstrained key rendered `unconstrained`. **Closed 2026-08-18 — shipped** (`c037d99`),
+  with the create form de-duplicating typed tags ordinal-ignore-case to match the CLI
+  (`fab600d`).
+- `AlarmsHubPublisher` broadcast alarm transitions with `current_value`/`limit_value`
+  unredacted — the `ShowTagValues` redaction covered only the events hub mirror.
+  **Closed 2026-08-18** together with the `/browse` residual: `ShowTagValues` now gates
+  all three seams (`eff17d1`, `1ea6f60`, `e50ec49`).
+- The alarm probes' remaining questions (ack-leg GUID stability, `@COUNT` semantics).
+  **Narrowed 2026-08-18** by a second probe attempt that used the secured-write verb the
+  first attempt lacked (`90331b6`, `540a118`):
+  - `@COUNT` — **answered.** It reports records in the reply, not matching records in the
+    provider, so exact truncation detection through it is permanently refuted; the
+    heuristic in `IsTruncatedFetch` stays as the only available signal.
+  - clear-then-re-raise GUID — **answered.** The re-raise carries a new GUID that replaces
+    the record rather than coexisting with it, which makes the existing `Clear`+`Raise`
+    handling correct as written.
+  - ack leg — **still blocked**, now with a sharper cause: the ack returns `rc=0` and is
+    accepted but inert, so the GUID never moves. Remaining unblock paths are recorded in
+    `docs/AlarmProbeFindings.md`.

+## As-built notes (execution record, 2026-08-18)
+
+All 9 tasks completed on `feat/followup-closeout`; every classification-driven review
+chain resolved **Approved**. The final integration review came back *Ready with
+reservations* — all of its non-blocking findings were fixed in `c3c603f`, leaving no
+open review item.
+
+Verification: macOS `NonWindows.slnx` 0W/0E; gateway filtered suites green (dashboard
+276/276, alarm suites green); `scripts/check-codegen.ps1` 4/4 on macOS. **The full
+five-language client matrix ran locally for the first time** — dotnet 133 passed /1
+skipped, Go clean, Rust 108, Python 168 passed /1 skipped, Java 131. Windev at `90331b6`:
+full `slnx` 0W/0E (one transient MSB4166 node crash, clean on retry), worker x86 523
+passed / 11 skipped plus **one pre-existing deterministic failure that reproduces on
+`main`** (`WorkerPipeSessionTests.RunAsync_LongInFlightCommandThatKeepsPumping_DoesNotFaultAndDeliversReply`),
+gateway 1151/1151 on rerun (the known windev load flake), live MXAccess smoke 8/8. The
+comment- and prose-only commits landed after `90331b6` are unverified on windev by
+design; they need only a cheap tip re-build there.
+
+- **A session-limit outage interrupted four reviewers mid-run.** All four resumed
+  cleanly on retry; no review was lost or silently truncated.
+- **Task 2 surfaced two plan defects, both absorbed rather than deferred.** The spec
+  claimed the Java CLI renders alarm frames as generic JSON; it is in fact an exhaustive
+  `switch` that does not compile without an arm for the new case. The spec's work list
+  also omitted the Java generated-bindings tree.
+- **A reviewer's Minor-2 was refuted, and the doc defect behind it fixed instead.** The
+  finding assumed alarm records coexist after a re-raise; fetch evidence from the probe
+  rig shows the new GUID replaces the record. The prose that implied coexistence was
+  corrected rather than the code.
+
+Follow-ups recorded, not started:
+
+- `WorkerPipeSessionTests.RunAsync_LongInFlightCommandThatKeepsPumping_DoesNotFaultAndDeliversReply`
+  fails deterministically on windev **and on `main`** — pre-existing, needs its own
+  investigation.
+- `check-codegen.ps1` Check 4 is unrunnable on Windows: the `protoc-gen-go` version banner
+  carries a `.exe` suffix that the exact-string compare in
+  `clients/go/generate-proto.ps1:10,55` does not tolerate.
+- Windev has `protoc-gen-go-grpc` 1.6.1 against the repo's pinned 1.6.2.
+- `clients/java`'s `checkGeneratedClean` is dead under Gradle 9 (`Project.exec` was
+  removed); it needs `ExecOperations` injection to work again.
+- `SettingsPage` renders every `EffectiveDashboardConfiguration` member except
+  `RecentFaultLimit` / `RecentSessionLimit` (pre-existing, predates this branch).
+- The ack-leg probe stays blocked; unblock paths are in `docs/AlarmProbeFindings.md`.
+- The dashboard `AlarmsPage` truncation banner is still poll-driven — it could consume
+  the new `snapshot_status` feed frame instead.
+
+Explicitly decided, not an omission: **`../scadaproj/CLAUDE.md` needs no update.** The
+umbrella index records the *set* of `.proto` files this repo owns, and that set is
+unchanged — Task 1 added a message and a field inside an existing proto, not a new
+contract file.
