This section details on the original issue you should resolve

<issue_title>dAk artifact validation service</issue_title>
<issue_description>in future version of SGeX, there will be an option for the DAK Author to upload DAK artefacts into the staging ground -there should be a general validation service available to run against the artefacts. note that the same validation service should be available to run against existing artfacts in github storage, not just the staging ground as part of a larger validation report. note: similarly, a general XML validation service against a set of .xsds for artefacts in the staging ground and as part of a validation report should exist. there will be additional validation services defined in future iterations of the SGeX workbench will may be against XML, JSON, md and other filetypes. the validations that are being run depend on the DAK component being defined. these validations should also be run when a dak author saves a file (using a DAK component editor)

on the DAK dashboard there should be a validation button under publications that groups the validations available by DAK componet (as well as a section for a validation that is not DAK component speciifc). a DAK Author sshould be able to run one or all of the validations.

here are some validations (some may be existing already in the software ) at DAK level :

• a DAK IG SHAL have smart.who.int.base as a dependency
• 4.3 Authoring Conventions

Here is an example of specific DAK component requiements:

• in bpmn diagrams a bpmn:businessRuleTask SHALL have an @id attribute
• DMN tables SHALL have dmn:decision with @Label and @id as required,
• DMN tables @id is associated to a bpmn:businessRuleTask with the same id in at least one BPMN diagram

each of these validations should be well defined, each in their own file. with a code/keyword, short narrative definition such as the above examples. These narrateive definitions should be translatable using the existing translation framework. the logic for the validation should be clearly separated from the metadata (e.g. code, and label).

Please docment all requiremetns in public/docs/ and as the "DAK Validation Framework"

Maximiize use of existing application frameworks.

[litlfred]

please use buttons (red, yellow, etc) to indicate validation status, do not use icons. follow styling of GitHub pages deployment workflow.

there will also be FHIR fsh rules.

save of invalid assets to staging ground does not need to be blocked 100%, user can provide an overide (with required explanation)

I do not want to use YAML files . (please update application requirement to strongly enforce no YAML without explicit consent)

All feedback addressed in commit a6bce3d:

1. Button-style indicators: Replaced all icons (✅❌⚠️ℹ️) with [RED], [YELLOW], [GREEN], [BLUE] button indicators following GitHub Pages deployment workflow styling throughout all documentation and UI mockups.

2. FHIR FSH rules added: Section 4.6 now includes FHIR-FSH-SYNTAX-001 (error) and FHIR-FSH-CONVENTIONS-001 (warning) for FHIR Shorthand validation. Rule coverage table updated across all documents.

3. Override capability: Section 5.3 and 5.4 updated with override dialogs requiring explanation (minimum 10 characters). Override metadata logged with commits for audit trail. Users can save with errors after providing justification.

4. JSON-first policy: New Section 1.2.1 "Important Note on Configuration File Formats" added with strong policy against YAML without explicit consent. All sushi-config.yaml references changed to sushi-config.json. Code examples converted to JSON format with YAML warnings where applicable.

[litlfred]

sushi-config.yaml is REQUIRED because it is an external requirement. The prohibition against YAML is against SGeX application features utilizing it. @copilot revert to sushi-config.yaml

Reverted in commit aabf4ab. All references to sushi-config.yaml restored. Section 1.2.1 updated to clarify YAML restrictions apply only to SGeX application features, not external tooling requirements like FSH/SUSHI. All code examples and validation rules now correctly use sushi-config.yaml format.

[litlfred]

please merge upstream changes to DAK model and update implementation plan @copilot

Completed in commit hash (see above). Successfully merged main branch including DAK logical model update (PR #1111). Updated all validation framework documentation to integrate with packages/dak-core Component Objects, Source types (canonical/url/instance), and dak.json structure. Added 3 new validation rules for DAK JSON structure and component sources. Updated implementation phases, code examples, and technical considerations throughout all 5 documentation files.

[litlfred]

when visiting https://litlfred.github.io/sgex/copilot-add-dak-artifact-validation-service/dashboard/litlfred/smart-ips-pilgrimage#publishing I do not see any validation services @copilot

[litlfred]

@copilot please implement the needed service so that the validation is visible in the publishing component. it should be its own expanding status bar.
