[TASK] Tangle Cloud: Deploy Argument Encoding & Request Flow Parity

[vutuanlinh2k2]

Goal

Fix request-arg encoding so deploy works with non-empty args, and support all three contract request variants (basic, with exposure, with security).

Status

🔴 BROKEN FOR NON-EMPTY ARGS — encodeServiceConfig throws when args are non-empty. Exposure request variant is unsupported.

Must-Have Tasks

#	Task	Type	Contract Function	Current State
3.1	Implement end-to-end request arg encoder aligned with contract schema	Bug fix	N/A	encodeServiceConfig throws on non-empty args
3.2	Support requestService (basic) variant	Feature	Services.requestService()	Partially working
3.3	Support requestServiceWithExposure variant	Feature	Services.requestServiceWithExposure()	Not implemented
3.4	Support requestServiceWithSecurity variant	Feature	Services.requestServiceWithSecurity()	Partially implemented
3.5	Add hook selection logic to auto-route to correct variant	Feature	N/A	Basic/security only
3.6	Add explicit validation and user-readable errors before tx step	Feature	N/A	Not implemented

Files

• apps/tangle-cloud/src/pages/blueprints/[id]/deploy/page.tsx — deploy page
• libs/tangle-shared-ui/src/data/graphql/useServiceRequest.ts — request hook
• ../tnt-core/src/interfaces/ITangleServices.sol — contract interface
• ../tnt-core/src/core/ServicesLifecycle.sol — contract implementation

Test Criteria

• Deploy succeeds with empty request args
• Deploy succeeds with non-empty structured request args
• Exposure-only request variant can be selected and submitted
• Security request variant works with asset/security combinations
• User sees readable validation errors for malformed args before tx step
• Correct contract function is called based on deploy configuration

Nice-to-Have

• Arg schema auto-detection from blueprint metadata
• Preview of encoded args before submission
