Summary

This pull request implements Track 1: End-to-End Execution Modes, Capability Registry, and UI Integration (addressing Issue #35 Phases 3–5 and Issue #21).

It unifies the application's runtime reasoning surfaces into a strongly typed, observable execution model spanning backend schemas, GraphQL APIs, and the React frontend.

Key Changes

Phase 3: Shared Run Contracts & Capability Registry (execution_modes.py)

• Pydantic v2 Schemas: Defined RunRequest, RunResult, RunEvent, RunDiagnostics, PlanStepDiagnostic, SubtaskDiagnostic, ReflectionDiagnostic, and AgentAttribution.
• Capability Registry: Established CAPABILITY_REGISTRY cataloging supported execution modes (collaborative, advanced_pipeline) and gated future modes (tree_of_thought gated on Issue Implement true Tree-of-Thought search with bounded branching, evaluation, pruning, and end-to-end integration #36).
• Fail-Closed Gating: Gated modes return deterministic RunResult(status="gated") with zero LLM provider or external network calls.
• Polymorphic Input Normalization: RunRequest normalizes tasks and conversations bidirectionally, accepting dicts, strings, and GraphQL input types.
• Zero Import-Time Side Effects: Handlers dynamically import orchestrators (conversation_manager.run_conversation, advanced_prompting.AdvancedPromptEngineer) inside dispatcher functions, keeping module imports completely pure.

Phase 4: GraphQL Schema Extensions (schema.py)

• Queries & Mutations:
  • Query.execution_modes: Exposes registered capabilities, enabled status, descriptions, and gating issue references.
  • Mutation.run_execution: Dispatches arbitrary registered modes, returning unified RunResultType with diagnostics, events, and telemetry.
  • Mutation.run_advanced_pipeline: Dedicated resolver for AdvancedPromptEngineer.main(task) with structured telemetry logging.
• Backward Compatibility: Fully preserves Query.hello, Mutation.run_conversation, and Mutation.submit_feedback.
• Structured JSON Logging: Added structured logging for request life cycles, durations, and diagnostic extraction.

Phase 5: React UI Observability & Diagnostics (collaborative-assistant-frontend/)

• Mode Selection: Updated AssistantConfigPanel.tsx with an Execution Mode selector (collaborative, advanced_pipeline, disabled tree_of_thought with Issue Implement true Tree-of-Thought search with bounded branching, evaluation, pruning, and end-to-end integration #36 badge).
• Reasoning Diagnostics Panel: Created ReasoningDiagnosticsPanel.tsx displaying complexity scores, step budgets, reflections, step rewards, plan subtasks, agent attributions, and a collapsible chronological event log.
• Structured Output Rendering: Created StructuredOutputRenderer.tsx with dedicated formatters for code syntax highlighting, JSON tree/copy, CSV table/raw view, and Markdown.
• Hook Layer: Implemented useRunExecution.ts providing typed Apollo execution with loading states and error handling.
• Zero Regressions: ConversationPage.tsx preserves legacy collaborative integration test mocks while enabling multi-mode execution.

Offline Qualification & Verification Evidence

All tests were executed under the fail-closed network denial harness (tools/run-offline.ps1 and tools/run-frontend-offline.ps1):

1. Backend Offline Test Suite:

   ./tools/run-offline.ps1 -PytestArgs '-q'
   # Result: 206 passed, 0 failed, 0 skipped (100% pass rate, +58 new tests over 148 baseline)

   • Includes 41 tests in test_execution_modes.py, 13 tests in test_empirical_challenger_2.py, 6 in test_graphql_contract.py, and 48 in test_advanced_prompting.py.
2. Frontend Offline Test Suite:

   ./tools/run-frontend-offline.ps1 -Action test
   # Result: 124 passed, 0 failed across 13 test files (100% pass rate, +13 new tests over 111 baseline)

3. Frontend Production Build:

   ./tools/run-frontend-offline.ps1 -Action build
   # Result: PASS (zero TypeScript errors, Vite bundle built cleanly)

4. Frontend Lint Check:

   ./tools/run-frontend-offline.ps1 -Action lint
   # Result: PASS (0 ESLint errors, 0 warnings)

5. Network Denial Guard:

   ./tools/run-frontend-offline.ps1 -Action guard
   # Result: PASS (Node outbound socket/DNS denial verified)
