# Script-log Engine Emit + Scripted-Alarm Runtime — Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: use superpowers-extended-cc:subagent-driven-development
> (or executing-plans) to implement this plan task-by-task.

**Goal:** Make the Script-log page tail real script output, and stand up scripted
alarms end-to-end including real OPC UA Part 9 condition nodes + client ack.

**Architecture:** Three sequenced layers off one shared seam (a root script logger
fanning to file + companion + a new DPS topic sink). Layer 0 = emit (F8 live). Layer 1
= F9 engine runtime on the Akka equipment-namespace runtime. Layer 2 = F14b real Part 9
nodes + events + inbound ack. Design: `docs/plans/2026-06-10-script-log-and-scripted-alarm-runtime-design.md`.
Verified gap analysis: `pending.md`.

**Tech:** .NET 10, Akka.NET, EF Core (SQL prod / InMemory tests), Serilog, OPC
Foundation UA .NET Standard, xUnit + Shouldly, Akka TestKit. No bUnit.

**Hard rules (every task):** stage by explicit path — never `git add .`; never stage
`sql_login.txt` or `src/Server/ZB.MOM.WW.OtOpcUa.Host/pki/`; never echo the gateway API
key into a new tracked file; no force-push, no `--no-verify`. **No Configuration entity
/ EF migration change** (`ScriptedAlarmState` table already exists). Agent does **not**
sign in to the AdminUI — the user drives live `/run`.

**Branch:** `feat/scriptlog-alarm-runtime` off `master @ df4c2657` (design committed there).

**Reference patterns to mirror:** `VirtualTagHostActor` (host actor shape),
`EfAlarmActorStateStore` (EF store shape), the `{{equip}}` two-seam parity work
(`Phase7Composer` ↔ `DeploymentArtifact`), `RoslynVirtualTagEvaluator` (evaluator).

# LAYER 0 — Shared script-log emit + F8 live

### Task 0: Branch + test-project check

**Classification:** small · **~2 min** · **Parallelizable with:** none

**Files:** none created (branch + verification only)

**Steps:**
1. `git switch -c feat/scriptlog-alarm-runtime` (off `master @ df4c2657`).
2. Confirm `tests/Core/ZB.MOM.WW.OtOpcUa.Core.Scripting.Tests/` exists and is in the
   `.slnx` (it does — `ScriptLoggerFactoryTests.cs` lives there). New Layer-0 tests land
   here. Confirm `tests/Server/ZB.MOM.WW.OtOpcUa.Runtime.Tests/` for Layer-1 tests.
3. `dotnet build ZB.MOM.WW.OtOpcUa.slnx` — green baseline. Commit nothing.

### Task 1: `IScriptLogPublisher` + `ScriptLogTopicSink`

**Classification:** standard · **~4 min** · **Parallelizable with:** none

**Files:**
- Create: `src/Core/ZB.MOM.WW.OtOpcUa.Core.Scripting/IScriptLogPublisher.cs`
- Create: `src/Core/ZB.MOM.WW.OtOpcUa.Core.Scripting/ScriptLogTopicSink.cs`
- Test: `tests/Core/ZB.MOM.WW.OtOpcUa.Core.Scripting.Tests/ScriptLogTopicSinkTests.cs`
- Maybe modify: `Core.Scripting.csproj` (add ProjectReference to `Commons` for
  `ScriptLogEntry` if not already referenced — verify first).

**Step 1 — failing tests** (`ScriptLogTopicSinkTests`):
- A `LogEvent` (Information) with properties `ScriptId="S1"`, `VirtualTagId="V1"`,
  `EquipmentId="EQ1"`, message `"hello"` → publisher receives one `ScriptLogEntry` with
  those fields, `Level=="Information"`, `Message=="hello"`.
- `AlarmId` property maps to `ScriptLogEntry.AlarmId`; absent properties → null fields.
- A `Debug` event with default `minLevel=Information` → publisher receives **nothing**.
- Template message renders (`"v={V}"` + prop V=3 → `"v=3"`).
Use a fake `IScriptLogPublisher` capturing entries.

**Step 2 — run, expect fail** (types don't exist).

**Step 3 — implement:**
```csharp
public interface IScriptLogPublisher { void Publish(ScriptLogEntry entry); }

public sealed class ScriptLogTopicSink : ILogEventSink
{
    private readonly IScriptLogPublisher _publisher;
    private readonly LogEventLevel _min;
    public ScriptLogTopicSink(IScriptLogPublisher publisher,
        LogEventLevel min = LogEventLevel.Information) { _publisher = publisher; _min = min; }
    public void Emit(LogEvent e)
    {
        if (e is null || e.Level < _min) return;
        string? P(string k) => e.Properties.TryGetValue(k, out var v)
            && v is ScalarValue { Value: string s } ? s : null;
        _publisher.Publish(new ScriptLogEntry(
            ScriptId: P("ScriptId") ?? P("ScriptName") ?? "unknown",
            Level: e.Level.ToString(),
            Message: e.RenderMessage(),
            TimestampUtc: e.Timestamp.UtcDateTime,
            VirtualTagId: P("VirtualTagId"), AlarmId: P("AlarmId"), EquipmentId: P("EquipmentId")));
    }
}
```
(Property-name constants — reuse/extend `ScriptLoggerFactory`'s `ScriptNameProperty`;
add `ScriptIdProperty`/`VirtualTagIdProperty`/`AlarmIdProperty`/`EquipmentIdProperty`.)

**Step 4 — run tests, expect pass. Step 5 — commit** (`git add` the 3 files by path).

---

### Task 2: Root script logger + `DpsScriptLogPublisher` + Host wiring

**Classification:** standard · **~5 min** · **Parallelizable with:** none (depends T1)

**Files:**
- Create: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/Scripting/DpsScriptLogPublisher.cs`
  (or Host — wherever the `ActorSystem`/`Mediator` is reachable at construction).
- Create: `src/Server/ZB.MOM.WW.OtOpcUa.Host/Logging/ScriptRootLoggerFactory.cs`
  (builds the root `ILogger`: rolling `scripts-*.log` + `ScriptLogCompanionSink` +
  `ScriptLogTopicSink`).
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Host/Program.cs` (build + register root logger;
  register `IScriptLogPublisher`).
- Test: `tests/.../Core.Scripting.Tests/ScriptRootLoggerFanoutTests.cs` (or Host.Tests).

**Steps (TDD):**
1. Failing test: a logger built by `ScriptRootLoggerFactory` with a fake publisher +
   in-memory companion → an `Error` event reaches the companion mirror AND the topic
   publisher; a `Debug` event reaches neither topic nor companion (file only). (Assert
   via fakes; don't assert the physical file.)
2. Implement `DpsScriptLogPublisher` — ctor takes the DPS mediator `IActorRef` (or
   `ActorSystem`); `Publish` → `mediator.Tell(new Publish("script-logs", entry))`
   (topic constant `VirtualTagActor.ScriptLogsTopic`).
3. Implement `ScriptRootLoggerFactory.Build(IScriptLogPublisher, config)` →
   `LoggerConfiguration().WriteTo.File(...).WriteTo.Sink(new ScriptLogCompanionSink(Log.Logger))
   .WriteTo.Sink(new ScriptLogTopicSink(publisher, minLevel)).CreateLogger()`.
4. `Program.cs`: resolve the mediator after the ActorSystem is up; register
   `IScriptLogPublisher` (singleton) + the root `ILogger` (keyed/named for scripts).
   Min-level from config (`Scripting:LogTopicMinLevel`, default `Information`).
5. Run + commit by path.

### Task 3: Rewire evaluators to the root script logger

**Classification:** standard · **~5 min** · **Parallelizable with:** none (depends T1, T2)

**Files:**
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Host/Engines/RoslynVirtualTagEvaluator.cs`
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Host/Engines/RoslynScriptedAlarmEvaluator.cs`
- Modify: `src/Core/ZB.MOM.WW.OtOpcUa.Core.Scripting/ScriptLoggerFactory.cs` (bind the
  full property set, not just `ScriptName`).
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Host/Program.cs` (inject root logger into the
  evaluators).
- Test: `tests/.../Core.Scripting.Tests/` — evaluator emits via fake publisher.

**Steps:**
1. Failing test: a `RoslynVirtualTagEvaluator` built with a root logger wired to a fake
   publisher; evaluate a script `ctx.Logger.Information("hi"); return 1;` → publisher
   gets one entry with `ScriptId`/`VirtualTagId` bound and `Message=="hi"`.
2. Replace the static `ScriptLogger` field with a ctor-injected root `ILogger`. Per
   evaluation, `var log = _root.ForContext("ScriptId", id).ForContext("VirtualTagId", virtualTagId)`
   (+ `EquipmentId` when available) and pass into the `VirtualTagContext`. Same for the
   alarm evaluator (binds `AlarmId`).
3. `ScriptLoggerFactory`: add a `Create(scriptId, virtualTagId?, alarmId?, equipmentId?)`
   overload binding the standard properties (keep the old `Create(scriptName)` for
   compatibility).
4. `Program.cs`: pass the root logger to both evaluator registrations.
5. Run + commit by path.

> Note: `IVirtualTagEvaluator.Evaluate` carries `virtualTagId`; in the live path
> `scriptId == virtualTagId`, so Layer 0 binds both from it. Threading a distinct
> `EquipmentId` (nice-to-have on the page) is optional here — if it requires an
> interface change, defer it to a Layer-1 follow-up rather than expanding T3.

---

### Task 4: Live-verify Layer 0

**Classification:** verification · **Parallelizable with:** none (depends T2, T3)

**Steps:**
1. Rebuild docker-dev central nodes (user-driven `/run`). Author a virtual tag whose
   script calls `ctx.Logger.Information(...)`.
2. Open `/script-log`; drive the dependency so the script evaluates; confirm the line
   appears live with the right ScriptId/level. Confirm Debug stays off the page,
   Information+ shows.
3. **Agent does not sign in** — user signs in and drives. Record outcome. No code unless
   a defect surfaces (→ new fix task).

# LAYER 1 — F9 engine runtime

### Task 5: `EquipmentScriptedAlarmPlan` + Phase7Composer enrichment

**Classification:** standard · **~5 min** · **Parallelizable with:** Task 7, Task 8

**Files:**
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.OpcUaServer/Phase7Composer.cs` (new record +
  build the enriched list from `ScriptedAlarm` + `Script` rows).
- Test: `tests/Server/ZB.MOM.WW.OtOpcUa.Server.Tests/Phase7/` (or wherever Phase7Composer
  is tested) — new `Phase7ComposerScriptedAlarmTests.cs`.

**Steps:**
1. Failing test: compose two equipments each with a scripted alarm referencing a script;
   assert each `EquipmentScriptedAlarmPlan` carries the resolved `PredicateSource`,
   extracted `DependencyRefs` (via `DependencyExtractor`), `AlarmType`, `Severity`,
   `MessageTemplate`, `HistorizeToAveva`, `Retain`, `Enabled`, `Name`.
2. Add `public sealed record EquipmentScriptedAlarmPlan(string ScriptedAlarmId, string
   EquipmentId, string Name, string AlarmType, int Severity, string MessageTemplate,
   string PredicateScriptId, string PredicateSource, IReadOnlyList<string> DependencyRefs,
   bool HistorizeToAveva, bool Retain, bool Enabled);`
3. In `Compose`: join `ScriptedAlarm.PredicateScriptId → Script.SourceCode`; run
   `DependencyExtractor.Extract(source).Reads` (∪ `MessageTemplate` token paths) for
   `DependencyRefs`; project into the new list on the composition result. Skip
   `Enabled=false` alarms (or carry the flag — carry it; host decides). Drop alarms whose
   script is missing with a structured warning (don't throw the whole compose).
4. Run + commit by path.

---

### Task 6: DeploymentArtifact parity for the alarm plan

**Classification:** standard · **~5 min** · **Parallelizable with:** Task 7, Task 8 (depends T5)

**Files:**
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/Drivers/DeploymentArtifact.cs`
  (encode/decode `EquipmentScriptedAlarmPlan`; add
  `Phase7CompositionResult.EquipmentScriptedAlarms`; filter-by-equipment like
  `EquipmentVirtualTags` at :263).
- Test: `tests/Server/ZB.MOM.WW.OtOpcUa.Runtime.Tests/` — artifact round-trip + parity
  with the Composer for the same input.

**Steps:**
1. Failing test: build a composition via `Phase7Composer`, serialize to artifact, parse
   back → `EquipmentScriptedAlarms` is byte-identical (same discipline as the `{{equip}}`
   parity tests). Equipment-filter test (only alarms for resident equipment survive).
2. Add the field to `Phase7CompositionResult`; mirror the `EquipmentVirtualTags`
   encode/decode/filter exactly (`:202`, `:263`).
3. Run + commit by path.

---

### Task 7: `DependencyMuxTagUpstreamSource`

**Classification:** standard · **~4 min** · **Parallelizable with:** Task 5, Task 6, Task 8

**Files:**
- Create: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/ScriptedAlarms/DependencyMuxTagUpstreamSource.cs`
  (implements `Core.ScriptedAlarms`/`Core.VirtualTags` `ITagUpstreamSource`).
- Test: `tests/Server/ZB.MOM.WW.OtOpcUa.Runtime.Tests/ScriptedAlarms/DependencyMuxTagUpstreamSourceTests.cs`

**Steps:**
1. Failing tests: `Push(path, snapshot)` updates cache so `ReadTag(path)` returns it;
   `SubscribeTag(path, obs)` → `obs` fires on the next `Push`; `ReadTag` for an unknown
   path returns a Bad-quality snapshot; dispose removes the observer.
2. Implement: a thread-safe cache (`ConcurrentDictionary<string, DataValueSnapshot>`) +
   per-path observer list; `Push` updates cache then invokes observers; `ReadTag` reads
   cache (Bad if absent); `SubscribeTag` returns an `IDisposable` that deregisters. The
   host actor calls `Push` from its `DependencyValueChanged` handler. Value wrap:
   `new DataValueSnapshot(value, StatusCode:0, ts, ts)`.
3. Run + commit by path.

---

### Task 8: `EfAlarmConditionStateStore : IAlarmStateStore`

**Classification:** standard · **~5 min** · **Parallelizable with:** Task 5, Task 6, Task 7

**Files:**
- Create: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/ScriptedAlarms/EfAlarmConditionStateStore.cs`
- Test: `tests/Server/ZB.MOM.WW.OtOpcUa.Runtime.Tests/ScriptedAlarms/EfAlarmConditionStateStoreTests.cs`
  (in-memory EF).

**Steps:**
1. Failing tests (in-memory `OtOpcUaConfigDbContext`): `SaveAsync(state)` then
   `LoadAsync(alarmId)` round-trips Enabled/Acked/Confirmed/Shelving(+UnshelveAtUtc)/
   LastAck*/LastConfirm*/Comments; `LoadAsync` of an unknown id → null; `ActiveState`
   is **not** persisted (a saved state's Active is ignored on load — load returns the
   stored operator state, Active defaults). Comments JSON round-trips.
2. Implement mapping `AlarmConditionState` ↔ `ScriptedAlarmState` entity (mirror
   `EfAlarmActorStateStore`'s `IDbContextFactory` upsert pattern; serialize
   `ImmutableList<AlarmComment>` ↔ `CommentsJson`). Map enum states ↔ the entity's string
   columns.
3. Run + commit by path.

### Task 9: `ScriptedAlarmHostActor`

**Classification:** high-risk · **~5 min** · **Parallelizable with:** none (depends T6, T7, T8; needs Layer 0 T2/T3 root logger)

**Files:**
- Create: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/ScriptedAlarms/ScriptedAlarmHostActor.cs`
- Test: `tests/Server/ZB.MOM.WW.OtOpcUa.Runtime.Tests/ScriptedAlarms/ScriptedAlarmHostActorTests.cs`
  (Akka TestKit + a real engine with the fake upstream, or a fake engine seam).

**Design:** mirrors `VirtualTagHostActor`. Owns one `ScriptedAlarmEngine` (built with the
`DependencyMuxTagUpstreamSource`, the `EfAlarmConditionStateStore`, a `ScriptLoggerFactory`
wrapping the **Layer 0 root logger**, and the engine's root logger). Message
`ApplyScriptedAlarms(IReadOnlyList<EquipmentScriptedAlarmPlan> Plans)`.

**Steps:**
1. Failing TestKit tests:
   - `ApplyScriptedAlarms` with one alarm → engine loaded (assert via a probe/seam);
     registers interest with the (probe) mux for the alarm's dep refs.
   - A `DependencyValueChanged` that makes the predicate true → the host tells the
     (probe) `OpcUaPublishActor` a `WriteAlarmState(alarmId, active:true, …)`, tells the
     (probe) historian an `AlarmHistorianEvent` (when `HistorizeToAveva`), and publishes
     an `AlarmTransitionEvent` on `alerts`.
   - Re-`ApplyScriptedAlarms` with a different set reloads the engine (LoadAsync replace).
2. Implement: on `ApplyScriptedAlarms`, build `ScriptedAlarmDefinition`s from the plans
   (map `AlarmType`→`AlarmKind`, `Severity`→`AlarmSeverity`, `EquipmentId`→`EquipmentPath`),
   `engine.LoadAsync`; register mux interest for `⋃ DependencyRefs`; on
   `DependencyValueChanged` → `_upstream.Push(...)`. Subscribe `engine.OnEvent` once →
   map `ScriptedAlarmEvent.Condition` to `(active, acknowledged)` →
   `OpcUaPublishActor.WriteAlarmState`; map → `AlarmHistorianEvent` → historian (if
   Historize); publish `AlarmTransitionEvent` on `alerts`. Dispose engine in `PostStop`.
3. Run targeted tests (`dotnet test --filter ScriptedAlarmHostActor`). Commit by path.

### Task 10: Spawn + apply in DriverHostActor

**Classification:** standard · **~4 min** · **Parallelizable with:** none (depends T9)

**Files:**
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/Drivers/DriverHostActor.cs`
  (spawn `ScriptedAlarmHostActor` next to `VirtualTagHostActor` ~:197; tell
  `ApplyScriptedAlarms(composition.EquipmentScriptedAlarms)` next to the vtag apply ~:532;
  add an override field for tests like `_virtualTagHostOverride`).
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/ServiceCollectionExtensions.cs` if the
  host needs new injected deps (EF store factory, root logger, historian ref).
- Test: extend `DriverHostActorTests` — apply pushes `ApplyScriptedAlarms`.

**Steps:** mirror the VirtualTag spawn/apply exactly; thread `_opcUaPublishActor`,
`_dependencyMux`, the EF store, the root logger, the historian actor ref. Run + commit.

---

### Task 11: Retire the orphaned actor + F9b evaluator

**Classification:** small · **~3 min** · **Parallelizable with:** none (depends T9, T10)

**Files:**
- Delete: `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/ScriptedAlarms/ScriptedAlarmActor.cs`
  (+ its tests) and `src/Server/ZB.MOM.WW.OtOpcUa.Host/Engines/RoslynScriptedAlarmEvaluator.cs`.
- Modify: `src/Server/ZB.MOM.WW.OtOpcUa.Host/Program.cs` (remove F9b DI registration,
  lines ~110-114) and any `IScriptedAlarmEvaluator` references. Keep
  `EfAlarmActorStateStore` only if nothing else uses it — otherwise delete with the actor.

**Steps:** delete, fix build, run full `dotnet test` for the touched projects, commit by
path. (If something unexpectedly depends on these, stop and surface — don't expand scope.)

---

### Task 12: Live-verify Layer 1

**Classification:** verification · **Parallelizable with:** none (depends T10, T11)

**Steps:** rebuild docker-dev; author a scripted alarm whose predicate references a live
tag; drive the tag; confirm the alarm node flips active/clear, the historian queue
advances (`/alarms/historian`), the `alerts`/Alerts page shows it, and predicate
`ctx.Logger` output appears on `/script-log`. User drives sign-in. Defects → new tasks.

# LAYER 2 — F14b real Part 9 + client ack

### Task 13: SDK research spike (DeepWiki)

**Classification:** small (research) · **~5 min** · **Parallelizable with:** Layer-1 tasks

**Steps:** Use the DeepWiki MCP (`OPCFoundation/UA-.NETStandard`) to confirm: how to
create + add an `AlarmConditionState` (and Limit/OffNormal/Discrete subtypes) under a
parent in a `CustomNodeManager2`; how to set ActiveState/AckedState/ConfirmedState/
ShelvingState/Severity/Retain; how transitions fire events (`ReportEvent`); how inbound
`Acknowledge`/`Shelve`/`Confirm` method calls are dispatched + where to hook them. Write
findings to `docs/v2/f14b-part9-sdk-notes.md` (committed). This de-risks T14-T17.

---

### Task 14: Real condition-node materialisation

**Classification:** high-risk · **~5 min** · **Parallelizable with:** none (depends T13)

**Files:** `src/Server/ZB.MOM.WW.OtOpcUa.OpcUaServer/OtOpcUaNodeManager.cs` (replace the
placeholder `[active, ack]` variable in `WriteAlarmState` / add a `MaterialiseAlarmCondition`
path per `AlarmType`); `Phase7Applier.cs` (call the new materialiser); tests where the
SDK allows (node existence/type assertions).

**Steps:** create real condition nodes on materialise; keep `WriteAlarmState` as a thin
shim during transition or replace its callers. Run + commit. (SDK threading: all via the
pinned `OpcUaPublishActor` dispatcher.)

---

### Task 15: Richer alarm-state bridge

**Classification:** standard · **~4 min** · **Parallelizable with:** Task 17 (depends T14, T9)

**Files:** `src/Server/ZB.MOM.WW.OtOpcUa.Runtime/OpcUa/OpcUaPublishActor.cs` (new message
carrying the full `AlarmConditionState`, not 2 bools); `ScriptedAlarmHostActor` bridge
(send the richer message); `OtOpcUaNodeManager` (apply full state to the condition).
Tests: message mapping.

---

### Task 16: Event firing on transition

**Classification:** high-risk · **~5 min** · **Parallelizable with:** none (depends T14, T15)

**Files:** `OtOpcUaNodeManager.cs` (`condition.ReportEvent(...)` on state change). Tests:
mapping/coverage where feasible; behaviour proven in T19.

---

### Task 17: Inbound method dispatch + ack plumbing

**Classification:** high-risk · **~5 min** · **Parallelizable with:** Task 15 (depends T14)

**Files:** `OtOpcUaNodeManager.cs` (wire Acknowledge/Confirm/AddComment/OneShotShelve/
TimedShelve/Unshelve handlers → route to a control-plane message → `ScriptedAlarmHostActor`
→ `engine.<Op>Async(conditionId, principal, comment, ct)`); the security gate at the
`AlarmAck` tier (reuse the LDAP-group→OPC-UA-permission map). Tests: method→engine routing
with a fake engine; permission gate allows/denies by tier.

---

### Task 18: AdminUI ack/shelve control

**Classification:** standard · **~4 min** · **Parallelizable with:** none (depends T17)

**Files:** `src/Server/ZB.MOM.WW.OtOpcUa.AdminUI/Components/Pages/ScriptedAlarms.razor`
(+ a control-plane command service) — ack/shelve buttons route to the same engine ops as
T17. Tests: the control-plane command service (no bUnit; live-verify the razor in T19).

---

### Task 19: Live-verify Layer 2 (Client.CLI)

**Classification:** verification · **Parallelizable with:** none (depends T16, T17, T18)

**Steps:** with docker-dev up, use `Client.CLI` `alarms` + `subscribe` to confirm a real
condition appears, fires events on transition, and a client `Acknowledge` round-trips
(state flips, event fires, persists). Confirm AdminUI ack does the same. User drives.

---

### Task 20: Docs + finish

**Classification:** small · **~5 min** · **Parallelizable with:** none (depends all)

**Files:** update `docs/ScriptedAlarms.md`, `docs/VirtualTags.md`, `docs/v2/Runtime.md`
(F8/F9 now wired), **correct the stale `docs/v2/phase-7-status.md` alarm-runtime status**,
add a CLAUDE.md note for the script-log emit + scripted-alarm runtime. Delete/condense
`pending.md` (its content now lives in the design + these docs). Then run
superpowers-extended-cc:finishing-a-development-branch (full `dotnet test`, merge to
master).

---

## Execution notes

- **Parallel dispatch:** Layer 0 is serial (T1→T2→T3→T4). Layer 1: **T5→T6** serial
  (composer→artifact parity); **T7, T8 parallel** with T5/T6 (disjoint files); T9 waits
  on T6/T7/T8; T10→T11→T12 serial. Layer 2: T13 first; **T15 ∥ T17** after T14; T16 after
  T15; T18 after T17; T19/T20 last.
- **One writer at a time** within a shared file (Program.cs touched by T2/T3/T11;
  OtOpcUaNodeManager by T14/T15/T16/T17 — serialize those).
- **Layer boundaries are natural checkpoints** — Layer 0 is independently shippable; pause
  for review after T4 and after T12 before committing to the Layer 2 SDK epic.
