The 3.10.0 milestone was about making the advertised smoke pack trustworthy enough to act like a real release gate. The main drift was in the repro-plus-fix scenario: the recipe docs were SDK-first, but the smoke still shelled out to CLI patch apply and asserted a human summary string.\n\nSwitch the smoke runner to use the structured SDK patch flow directly, remove the harness-only CLI dependency, and tighten the fake smoke tests so they prove the same structured path the docs recommend. This keeps smoke failures tied to real user-facing regressions instead of human-output formatting drift.\n\nPromote make smoke-use-cases as the trustworthy guest-backed verification path in the top-level docs, bump the release surface to 3.10.0, and mark the roadmap milestone done.\n\nValidation:\n- uv lock\n- UV_CACHE_DIR=.uv-cache uv run pytest --no-cov tests/test_workspace_use_case_smokes.py\n- UV_CACHE_DIR=.uv-cache make check\n- UV_CACHE_DIR=.uv-cache make dist-check\n- USE_CASE_ENVIRONMENT=debian:12 UV_CACHE_DIR=.uv-cache make smoke-use-cases
Turn the stable workspace surface into five documented, runnable stories with a shared guest-backed smoke runner, new docs/use-cases recipes, and Make targets for cold-start validation, repro/fix loops, parallel workspaces, untrusted inspection, and review/eval workflows.
Bump the package and catalog surface to 3.6.0, update the main docs to point users from the stable workspace walkthrough into the recipe index and smoke packs, and mark the 3.6.0 roadmap milestone done.
Fix a regression uncovered by the real parallel-workspaces smoke: workspace_file_read must not bump last_activity_at. Verified with uv lock, UV_CACHE_DIR=.uv-cache make check, UV_CACHE_DIR=.uv-cache make dist-check, and USE_CASE_ENVIRONMENT=debian:12 UV_CACHE_DIR=.uv-cache make smoke-use-cases.
