 # BatLLM Status

 BatLLM is a Python/Kivy research, education, and game project for exploring AI-mediated play, prompt quality, LLM behaviour, and local-model workflows. The repository currently contains a playable local desktop game, a standalone read-only Game Analyzer, local Ollama lifecycle and model-management helpers routed through `modelito`, release-bundle tooling, Homebrew formula generation, generated API reference artefacts, and maintained user/developer documentation.

 - Added `.github/dependabot.yml`, `.github/workflows/dependency-review.yml`, and `.github/workflows/pip-audit.yml`; `.github/workflows/ci.yml` now creates `.venv_BatLLM` before installing dependencies and running tests.
+- Updated `.github/workflows/ci.yml` again after PR validation: it now sets the same headless Kivy environment as the maintained multiplatform workflow, runs under `bash` on all platforms, invokes the virtual-environment interpreter directly instead of sourcing activation scripts, and narrows `compileall` back to project files instead of the whole checkout.
+- Added a dependency-graph preflight to `.github/workflows/dependency-review.yml` so the job skips cleanly when GitHub reports zero dependency-graph manifests for this repository.
 - Added repository and docs-site security guidance in `SECURITY.md` and `docs/SECURITY.md`.
 - Added `docs/STATE_AND_INSTALLATION.md` and `docs/MAINTAINER_AUDIT_CHECKLIST.md` for audit support and maintainer reference.
 - Retained the audit bundle artefacts and helper script at the repository root for traceability: `batllm-audit-pr.patch`, `batllm-audit-pr-overlay.zip`, `batllm-pr-implementation/`, and `scripts/apply_audit_pr.sh`.
-- Dependency Review workflow requires enabling the GitHub Dependency Graph in repository settings for full support.
+- GitHub GraphQL currently reports `dependencyGraphManifests.totalCount = 0` for this repository, so the dependency-review job currently skips instead of failing until GitHub exposes dependency-graph manifests.
+- PR `#33` exposed two CI workflow regressions before this update: Windows runners were trying to source `.venv_BatLLM/bin/activate` under PowerShell, and the CI workflow was missing the headless Kivy environment variables already used by `.github/workflows/multiplatform.yml`.
 - All other project state, architecture, and documentation remain as previously described.

+- `gh pr view --json statusCheckRollup` and targeted `gh run view --job ... --log` inspection identified two actionable CI failures on PR `#33`: Windows `Install dependencies` failed because PowerShell could not source `.venv_BatLLM/bin/activate`, and Ubuntu `Run tests` failed after launching `run_tests.py` in a workflow that lacked the headless Kivy environment used by `.github/workflows/multiplatform.yml`.
+- `ruby -e "require 'yaml'; YAML.load_file('.github/workflows/ci.yml'); puts 'yaml-ok'"` -> passed.
+- `git diff --check` -> passed.
+- `python3.12 -m venv /private/tmp/batllm-ci-check` plus `/private/tmp/batllm-ci-check/bin/python -m pip install -r requirements.txt pytest pylint` -> passed; used a temporary Python 3.12 venv because the local repo checkout's `.venv_BatLLM/bin/python` symlink points at a missing interpreter path.

+- `run_tests.py core` was not rerun locally after this CI fix because it is hard-wired to `.venv_BatLLM/bin/python`, and the local checkout's `.venv_BatLLM/bin/python` symlink targets a missing interpreter path; GitHub Actions logs and a temporary Python 3.12 venv were used instead for targeted workflow verification.
 - A headless launcher import attempt reached Kivy window initialisation and failed with `Unable to get a Window`; this is an environment limitation, not a substitute for manual GUI launch validation.
