GitHub Actions Caching Audit

• Audit date: 2026-03-18 (Asia/Tbilisi)
• Repository root: /home/standard/dspy_rag_in_repo_docs_and_impl1
• Git HEAD during verification: 1b7710d02eebb2384857a8bda0dc43a1984e9db4

Scope

This audit covers the repository-wide GitHub Actions cache follow-up:

• .github/workflows/ci.yml now uses actions/setup-python@v6 to activate the runner-cached Python version pinned in .python-version before syncing the project with uv.
• .github/workflows/ci.yml and .github/workflows/publish.yml now make the uv cache key explicit with .python-version, pyproject.toml, and uv.lock.
• .github/workflows/publication-pdf.yml now restores a cache of LaTeX auxiliary files so repeated publication builds can reuse .aux, .bbl, .fdb_latexmk, and related outputs.
• .github/workflows/publication-pdf.yml still uploads the built article PDF as a GitHub Actions artifact and still attempts a Discord notification when DISCORD_WEBHOOK is set, but notification remains non-fatal.
• .github/workflows/publication-pdf.yml now references the artifact URL with bracket notation so GitHub Actions accepts the workflow file and can expose the uploaded artifact link in the Discord message.
• .github/workflows/publication-pdf.yml now gates the Discord step via env.DISCORD_WEBHOOK instead of referencing secrets.* directly in the if expression, which keeps the workflow valid for GitHub Actions parsing.
• publication/README.md now documents the cached publication build behavior.
• tests/test_project_surfaces.py now verifies caching expectations across all repository workflows.

Executed Commands

Executed successfully in this turn:

• make hooks-install
• make paper-build
• make quality
• cargo build --manifest-path rust-cli/Cargo.toml

Observed before the cache changes:

• gh run list --limit 8 showed Publication PDF run 23187167908 for commit a9f0cee with conclusion success, confirming that the article build and artifact upload path were already healthy before the cache follow-up.

Notable results:

• make paper-build: passed, leaving publication/repository-rag-lab-article.pdf and publication/article-banner.png in sync with the publication sources
• make quality: passed with 50 tests and 88.62% total coverage
• cargo build --manifest-path rust-cli/Cargo.toml: passed

Current Verification Status

Configured and verified in this turn:

• Python CI caching: present through actions/setup-python@v6 plus astral-sh/setup-uv@v6
• Publish workflow caching: present through actions/setup-python@v6 plus astral-sh/setup-uv@v6
• Rust workflow caching: present through uv caching and Swatinem/rust-cache@v2
• Publication workflow caching: present through actions/cache@v4 for LaTeX auxiliary outputs
• Publication artifact upload: present through actions/upload-artifact@v6
• Discord publication notification: present and gated on DISCORD_WEBHOOK, but intentionally non-fatal if delivery fails
• Compile, lint, type checking, repository-surface verification, complexity reporting, tests, and coverage: present and passed through make quality
• Rust build: present and passed through cargo build --manifest-path rust-cli/Cargo.toml

Operational dependency not verifiable locally in this turn:

• End-to-end Discord delivery still depends on a configured DISCORD_WEBHOOK GitHub Actions secret in the repository or inherited workflow context.

Still absent or not exercised in this turn:

• UI or browser tests: none found in repository configuration
• Dedicated integration-test suite separate from the pytest surface: none found
• Live Azure endpoint validation: not executed in this turn
• Automated DSPy training compile path: not implemented in the repository today

Notes

• The CI and publish workflows were already using uv cache persistence; this turn makes the cache inputs explicit and lets GitHub-hosted runners provide the pinned Python interpreter from the standard runner cache.
• The publication workflow now has a real cache surface instead of rebuilding from a cold LaTeX auxiliary state on every run.
