Implements all the changes in docs:

docs/roadmaps/audit_outcome_roadmap.md
docs/roadmaps/P5_CORE_ARCHITECTURE_ROADMAP.md

This pull request introduces several important updates, primarily focused on enhancing project documentation, improving developer workflow instructions, and adding robust automated end-to-end (E2E) testing for the backend. The most significant change is the addition of a comprehensive E2E test workflow for continuous integration, ensuring backend reliability and providing optional performance smoke tests. There are also improvements to developer onboarding instructions and the inclusion of a detailed experiment evaluation report. Below are the key changes grouped by theme:

Automated Testing and CI/CD:

  • Added a new GitHub Actions workflow (.github/workflows/e2e-tests.yml) that runs E2E functional tests on every push and pull request, with an option to run performance smoke tests via manual dispatch. The workflow sets up the backend server, installs dependencies, runs tests, and uploads logs/artifacts on failure.

Documentation and Reporting:

  • Added a comprehensive evaluation report (## Comprehensive Evaluation Report.md) summarizing experimental methodology, results, issues, recommendations, and next steps for recursive introspection experiments. This report details both the strengths and current limitations of the evaluation pipeline and provides a roadmap for remediation and future validation.

Developer Workflow and Onboarding:

  • Updated the developer instructions (.github/instructions/IMPORTANT.md.instructions.md) to clarify environment activation, sequential action-taking, and proper use of the terminal and Python code blocks for a smoother onboarding and development experience.
  • Minor update to .github/copilot-instructions.md to remove the project title line, possibly for formatting or compatibility reasons.

Environment Configuration:

  • Added a Python virtual environment configuration file (MVP/.venv_mvp/pyvenv.cfg), specifying interpreter details for local development and reproducibility.

- Fix existential quantification query handling by extracting QuantifierNode.scope
- Implement complete forward chaining inference using UnificationEngine
- Fix AST attribute access: use connective_type (not connective) and operands[0]/[1] (not left/right)
- Fix Set subscripting error when iterating backend._statements
- Add proper rule retrieval from KSI internal storage
- Add _apply_bindings helper for grounding antecedents with variable substitutions

The forward chaining now correctly proves goals like Mortal(Socrates) from rules
like 'forall ?x. Human(?x) => Mortal(?x)' plus fact 'Human(Socrates)'.

Tests: 46/48 BDD tests passing (2 skipped require pre-running backend)
