Field-level @id and @unique gain declarative specs, the per-model index specs become factories over the uniform spec context, and every Mongo interpreter call site sources its spec from mongoAttributeSpecs. The interpreter input now requires the control mutation-default registry so the context it hands factories is complete.

📝 WalkthroughWalkthroughThe Mongo PSL interpreter now uses a context-aware attribute registry, reports unsupported attributes, and exposes registered specifications through Mongo family authoring configuration. Upgrade guidance and fixtures remove unsupported Mongo defaults and automatic timestamp attributes. ChangesMongo attribute specifications
Mongo migration cleanup
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds stricter unsupported-attribute diagnostics and upgrade guidance, but the upgrade rule may apply to SQL schemas and tell users to delete attributes they need; some registered field attributes may also be accepted where their behavior is ignored. Merge should wait for target-aware upgrade detection and resolution of the field-attribute handling risk. Sequence Diagram(s)sequenceDiagram

Reject registered attributes where their semantics cannot apply.
Lines 135-145 treat every registered field attribute as valid on composite-type fields. A schema such as type Address { code String @unique } produces no diagnostic, but composite processing emits no unique index. @id has the same problem. @unique on relation fields is also skipped by collectIndexes.
Restrict composite-type fields to supported attributes, or emit an attribute diagnostic for @id, @unique, and @relation in those contexts. Reject @unique when the field is a relation.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Describe @updatedAt as an automatic timestamp update.
The diagnostic currently says Mongo has no default-value lowering. @updatedAt represents automatic timestamp updates, not a default value. Update the interpreter message and this assertion so the explanation matches the unsupported behavior.
Suggested assertion text
- 'Field "Item.updatedAt" uses unsupported attribute "`@updatedAt`". Mongo has no default-value lowering; delete the attribute and set the timestamp in application code.',
+ 'Field "Item.updatedAt" uses unsupported attribute "`@updatedAt`". Mongo does not lower automatic timestamp updates; delete the attribute and set the timestamp in application code.',📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Scope this rule to Mongo projects.
The upgrade protocol runs a change when its detection matches a file; it does not apply target filtering. This rule can therefore match SQL schemas and instruct users to delete attributes that SQL requires. Add target-aware selection and use it here.

Refs TML-3229 — slice
mongo-attributes-registeredof the attribute-registry project (parent TML-3226); builds on the registry machinery merged in #30154. Runs in parallel with the SQL (TML-3228) and block-attribute (TML-3230) slices.At a glance
Before this PR the Mongo interpreter imported loose spec constants at each call site, had no spec at all for
@id/@unique(presence checks only), and dropped any attribute it did not recognise without a word — the@default(Active)above emitted fine and did nothing.Decision
This PR ships the Mongo half of central attribute registration:
