The harness's second run hit the wall the first one predicted: a fresh account has no pipx, so install.sh fell to `pip install --user`, and every Python a Mac offers — Homebrew and python.org alike — is externally managed, so PEP 668 blocked it. That fallback was never a fallback on macOS; it was a dead end that printed instructions. Replace it with a venv at ~/.bot-bottle/venv (BOT_BOTTLE_VENV to move it), with the console script symlinked into ~/.local/bin. PEP 668 does not apply inside a venv, and venv is stdlib, so unlike pipx there is nothing to bootstrap first. pipx stays the preferred path when present, so anyone already managing their Python apps that way is unaffected — and the post-install PATH check now asks pipx for PIPX_BIN_DIR instead of assuming ~/.local/bin. Keeping the venv under ~/.bot-bottle rather than ~/.local/share means the whole footprint stays in one directory, which is what lets the throwaway-account teardown remain a complete reset. This removes the PEP 668 pre-flight and the sysconfig user-scheme lookup, both of which existed only to serve the --user path. Their tests go with them: * `detects_externally_managed_python` asserted the check that is now moot; replaced by one asserting pipx is still preferred when present. * `checks_pip_usable_before_fallback` pinned a pip probe that no longer runs; replaced by one asserting the venv's own pip does the install, since using the base interpreter's would install outside the venv. * `resolves_user_scripts_dir_not_hardcoded` and `macos_user_scheme_is_not_dot_local_bin` guarded the ~/Library/Python scripts-dir lookup. Nothing installs there now. The surviving "don't hardcode" concern is pipx's bin dir, which has its own test. Five tests are added for the new path: the venv fallback exists, no --user path survives, the venv is under the config dir, venv creation failure names python3-venv (Debian ships it separately), and the entry point is exposed outside the venv. Verified end to end in a sandbox HOME with a fresh-account PATH and no pipx: venv built, package installed, symlink created, `doctor` reached and green (python 3.14.5, macos-container ready), exit 0.

Docs
How this project records what it builds and why — and a guide to picking the right document for what you're capturing.
When to write which document
| Artifact | For |
|---|---|
Design workflow (docs/design-workflow.md) |
How discussion becomes canonical design, how dependencies are recorded, and when implementation may begin. |
Glossary (docs/glossary.md) |
Canonical term definitions — what words mean in this project. |
PRD (docs/prds/) |
A feature: what to build, scope, success criteria. |
Research note (docs/research/) |
A landscape/tradeoff investigation. |
Decision record (docs/decisions/) |
A decision that isn't itself a feature — a policy, a convention, a "we will / won't do this," or a load-bearing choice made inside a larger PRD that deserves to be discoverable on its own. |
A decision that's fully specified by a PRD doesn't need duplicating in a decision record. Write one when the decision would otherwise be buried in prose, lost in an issue thread, or have no in-repo home at all (small requests that don't merit a PRD; non-feature choices like merge strategy or a trust posture).
