# Follow-up tracker — template-inheritance UI gaps + CLI/validation footguns (2026-06-24 session)
|
||
|
||
**Status:** OPEN (tracker) · **Found:** 2026-06-24 · **Context:** live ops session on `wonder-app-vd03` (CvdReactor / Z28061 / Z28061Sim) — renaming the template, adding the LeakTest module, and adding MoveInType to the MESReceiver children.
|
||
**Components:** Central UI (#9), Template Engine (#1), CLI (#19), Configuration Database (#17)
|
||
|
||
Issues are listed worst-first. Severities are author estimates. None caused data loss; the runtime/flattened config and deployed instances are correct.

## 1. Template editor omits inherited-but-unmaterialized base attributes (user-reported)
|
||
**Severity:** Medium · **Components:** Central UI (#9), Template Engine (#1)
|
||
|
||
**Symptom:** On `/design/templates` → `LeftMESReceiver`, the **Attributes** tab does not list `MoveInType`. Same for `RightMESReceiver`. (Also missing from the list: all `MoveOut*` and `ScanStateCmd`.)
|
||
|
||
**Root cause:** `MoveInType` (String), the 12 `MoveOut*`, and `ScanStateCmd` live on the **base** `MESReceiver` template (id 3, 26 attrs). The derived children `LeftMESReceiver`/`RightMESReceiver` (ids 5/6) only have **12** materialized `IsInherited` rows (the `MoveIn*` basics) — the base attributes added *after* these children were derived were never materialized as child rows. The editor's main Attributes tab lists only the template's stored rows (`TemplateEdit.razor:187` → `GetAttributesByTemplateIdAsync(Id)`; count badge at `:415`), so the unmaterialized inherited members are invisible there.
|
||
|
||
**Not a runtime bug:** the flattener resolves the full chain, so `LeftMESReceiver.MoveInType` *is* in the flattened deploy config and is bound + live on the instances (`''` / `'na'`, Good). The page also has an "Effective inherited set" read-only preview (M9-T26b, `TemplateEdit.razor:465-491`) + a staleness banner (`:292-301`) that *do* surface these — but the main, editable Attributes list does not.
|
||
|
||
**Suggested fix:** in the Attributes tab, render the resolved inherited set (with inherited badges) rather than only materialized rows — or auto-materialize missing inherited rows on load. See #2 (shared root cause).

## 2. Derived templates carry incomplete/stale `IsInherited` row sets
|
||
**Severity:** Medium · **Components:** Template Engine (#1), Configuration Database (#17)
|
||
|
||
**Symptom:** `LeftMESReceiver`/`RightMESReceiver` (parent=3) have 12 stored attribute rows vs the base's 26. By contrast `LeftReactorSide`/`RightReactorSide` (parent=7) mirror the full 61. So derived row-sets are inconsistent.
|
||
|
||
**Root cause:** when a base attribute is added after a child is derived, the child's stored `IsInherited` placeholder rows are not auto-resynced. There is a staleness banner but no surfaced one-click "resync inherited members" action (or it exists and was never run for these children). This is the data root cause of #1.
|
||
|
||
**Suggested fix:** a "resync inherited members" command (CLI + UI) that materializes missing base members onto derived children; consider running it automatically when a base attribute is added.
|
||

## 3. Collision detector blocks adding attributes/compositions to ANY derived template
|
||
**Severity:** Medium-High · **Components:** Template Engine (#1)
|
||
|
||
**Symptom:** `template attribute add --template-id 5 --name MoveInType ...` fails with **13** "Naming collision" errors — the new attribute *plus all 12 pre-existing inherited rows*. Same class of failure when adding a composition to a derived template (hit earlier when trying to add `LeakTest` to `LeftReactorSide`).
|
||
|
||
**Root cause:** `CollisionDetector.CollectDirectMembers` (`CollisionDetector.cs`) emits every `template.Attributes` row — including `IsInherited` placeholders — with origin = child name, while `CollectInheritedMembers` emits the same names with origin = `parent '…'`. Two distinct origins for the same canonical name ⇒ reported as a collision. `AddAttributeAsync` (`TemplateService.cs:294`) and `AddCompositionAsync` (`:869`) both run `DetectCollisions`, so there is effectively **no supported API path to extend a derived template** — and the error message is misleading (it blames pre-existing inherited attrs, not the member you're adding).
|
||
|
||
**Workaround used this session:** add the feature module to the **base** template instead (LeakTest → base `ReactorSide` (7)); the flattener propagates it to all derivations.
|
||
|
||
**Suggested fix:** `CollectDirectMembers` should skip `IsInherited` rows (or the grouping should treat an inherited row and its parent source as the same origin), so only genuine cross-origin duplicates are flagged.

## 4. CLI `instance set-bindings` cannot set `DataSourceReferenceOverride`
|
||
**Severity:** Medium · **Components:** CLI (#19)
|
||
|
||
**Symptom:** `instance set-bindings --bindings` only accepts `[attributeName, dataConnectionId]` pairs (`InstanceCommands.cs` → `ConnectionBinding(name, connId)` 2-arg). The override is sent as `null`, and because `SetConnectionBindingsAsync` upserts `DataSourceReferenceOverride = b.DataSourceReferenceOverride` (`InstanceService.cs:340`), using the CLI on an attribute that already has an override would **wipe** it.
|
||
|
||
**Workaround used this session:** raw `POST /management` with `{"command":"SetConnectionBindings","payload":{...,"dataSourceReferenceOverride":"…"}}` — the wire contract `ConnectionBinding(AttributeName, DataConnectionId, DataSourceReferenceOverride?)` does carry the field; only the CLI omits it.
|
||
|
||
**Suggested fix:** add an optional 3rd element / `--ref-override` to the CLI bindings input.
|
||

||
## 5. CLI `template update` is full-replace, not partial
|
||
**Severity:** Low · **Components:** CLI (#19), Template Engine (#1)
|
||
|
||
**Symptom:** omitting `--description` on `template update` overwrites the stored description to NULL (`TemplateService.cs:124-125` assigns Name+Description unconditionally). Renaming a template silently drops its description unless you re-pass it.
|
||
|
||
**Suggested fix:** treat omitted optional fields as "leave unchanged" (nullable-not-provided vs explicit-null), or warn when a non-empty description would be cleared.
|
||
|

|
||
|
||
## 6. (Minor) CLI `template list`/`get` table output dumps every attribute
|
||
**Severity:** Low · **Components:** CLI (#19)
|
||
|
||
**Symptom:** `--format table template list` emitted ~171 KB (the full attribute set per template inline), unusable in a terminal. `--format json` is fine.
|
||
|
||
**Suggested fix:** a compact table projection (id/name/desc/#attrs/#comps) for list/get; reserve full attribute dumps for an explicit `--verbose`/`--detail` flag.
|
||

||
## 7. Central UI script editor false-flags batch/wait helpers (sandbox compile surface out of sync)
|
||
**Severity:** Medium · **Components:** Central UI (#9), Script Analysis (#25)
|
||
|
||
**Symptom:** In the template script editor (`/design/templates/{id}` → Scripts → Edit → Code), a script that calls `Attributes.WriteBatchAndWaitAsync(...)` (or on a child, `Children["X"].Attributes.WriteBatchAndWaitAsync(...)`) shows a red compile error:
|
||
`'SandboxAttributeAccessor' does not contain a definition for 'WriteBatchAndWaitAsync' ... (CS1061)`. Confirmed on `CvdReactor.MesMoveIn`; the same false error hits the base `MESReceiver.MoveIn`/`MoveOut`, which also use the helper.
|
||
|
||
**Root cause:** the editor validates against the Central UI's own sandbox surface (`CentralUI/ScriptAnalysis/SandboxScriptHost.cs`). Its `SandboxAttributeAccessor` only defines `this[string]`, `GetAsync`, `SetAsync`, `Resolve` — it is **missing `WriteBatchAndWaitAsync`, `WaitAsync`, and `WaitForAsync`** (none are defined anywhere in the CentralUI sandbox surface). The real runtime `AttributeAccessor` (`SiteRuntime/Scripts/ScopeAccessors.cs`) and the deploy-gate `ScriptCompileSurface` (`ScriptAnalysis`) both define them — so `template validate` reports the script clean and it deploys/runs fine. The error is purely the in-editor validator.
|
||
|
||
**Impact:** misleads authors and can block saving from the UI for any script using the batch-write/wait helpers, even though the script is valid. Authoring such scripts currently has to go through the management API (as was done for `MesMoveIn`).
|
||
|
||
**Suggested fix:** bring `SandboxAttributeAccessor` (and the sandbox composition/children accessors) to parity with the runtime `AttributeAccessor` — add `WriteBatchAndWaitAsync` / `WaitAsync` / `WaitForAsync` with matching signatures. Ideally enforce surface parity with a test, like the `RoslynScriptCompiler` "representative real script" corpus already does for `ScriptCompileSurface`. Three surfaces (runtime, deploy-gate `ScriptCompileSurface`, UI `SandboxScriptHost`) currently drift independently — consider collapsing to one source of truth.

||
### Minor note (not tracked separately)
|
||
The deploy-time unbound-binding validation returns one giant semicolon-joined error string (one clause per attribute). For 50–194 unbound attrs it's a wall of text; a structured/summarized error (count + grouped-by-module) would be friendlier.
