Branch: fix/a2a-error-detail-data-field
Commit Message: fix(a2a): rename A2aErrorDetail.details to data for JSON-RPC 2.0 compliance
Milestone: v3.8.0
Parent Epic: #933

Description

The A2aErrorDetail model in src/cleveragents/a2a/models.py uses a field named details for the optional error payload, but the JSON-RPC 2.0 specification and the project's own docs/reference/a2a.md both require this field to be named data.

Expected Behavior (from spec)

Per docs/reference/a2a.md (§Error Code Taxonomy), the error object wire format is:

{
  "jsonrpc": "2.0",
  "id": 42,
  "error": {
    "code": -32001,
    "message": "Plan not found",
    "data": { "plan_id": "01HXRCF1..." }
  }
}

The JSON-RPC 2.0 specification (Section 5.1) defines the error object as having code, message, and optionally data fields.

Actual Behavior

class A2aErrorDetail(BaseModel):
    code: str
    message: str
    details: dict[str, Any] = {}  # BUG: should be 'data'

When serialized, the error object produces {"code": ..., "message": ..., "details": {...}} instead of the required {"code": ..., "message": ..., "data": {...}}. This means any external A2A-compliant client parsing the error response will not find the data field.

Code location: src/cleveragents/a2a/models.py, line 71

Steps to Reproduce

Inspect src/cleveragents/a2a/models.py
Find A2aErrorDetail class
Observe field named details instead of data

Create an A2aErrorDetail with details and serialize:

A2aErrorDetail(code="NOT_FOUND", message="gone", details={"id": "x"}).model_dump()
# → {"code": "NOT_FOUND", "message": "gone", "details": {"id": "x"}}
# Expected: {"code": "NOT_FOUND", "message": "gone", "data": {"id": "x"}}

Subtasks

Rename A2aErrorDetail.details → data in src/cleveragents/a2a/models.py
Update all call sites that reference A2aErrorDetail.details
Update tests that reference the details field
Run nox -e typecheck and resolve any Pyright errors
Run nox -e unit_tests and confirm all Behave scenarios pass
Run nox -e coverage_report and confirm coverage remains ≥ 97%

Definition of Done

This issue is complete when:

A2aErrorDetail serializes to {\"code\": ..., \"message\": ..., \"data\": {...}} on the wire
No references to A2aErrorDetail.details remain in production code
All tests pass
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
All nox stages pass
Coverage >= 97%

Issue triaged by project owner:

State: Verified
Priority: High — The data field name is mandated by JSON-RPC 2.0 §5.1. Using details instead breaks wire format compliance.
Milestone: v3.8.0 (M9: Server Implementation)
MoSCoW: Must Have — JSON-RPC 2.0 error object schema is non-negotiable for protocol compliance. The spec and the class's own docstring both say data, confirming this is a straightforward naming bug.
Parent Epic: #933 (A2A Protocol Compliance)

Note: This is closely related to #2746 (same A2aErrorDetail model, code field type). Consider addressing both in a single PR.

Starting implementation on branch fix/a2a-error-detail-data-field.

Analysis complete:

Bug confirmed: A2aErrorDetail.details field in src/cleveragents/a2a/models.py must be renamed to data per JSON-RPC 2.0 §5.1
The details= references in transport.py and events.py are constructor parameters to A2aNotAvailableError (a different class), not A2aErrorDetail — those are unaffected
No existing tests reference A2aErrorDetail.details directly; the wire format feature file tests serialization but doesn't check for the details key specifically
Will add a TDD scenario to verify A2aErrorDetail serializes with data field (not details)

Difficulty assessment: Low → starting at sonnet tier.
