An always-activated ~/.venv puts ~/.venv/bin first on PATH. The audit
took shutil.which's answer and reported ~/.venv/bin/black (25.11.0,
"via manual") as the installation. The upgrade updated the real uv tool
in ~/.local/bin to 26.5.1, the re-audit found the venv copy again, and
black, isort and python@3.14 stayed "outdated" run after run.
Environments are not installations. reconcile.py and capability.sh
already skip venv/conda bin dirs; detection.py did not. The predicate
moves from reconcile.py to detection.py (reconcile imports it), and
find_paths plus the multi-version lookup search PATH without venv dirs.
Catalog version_commands name the tool ("black --version"), so they
now run with the detected binary's dir first and venv dirs removed.
Measured on this machine, 4 of 117 tools change: black, isort and
python@3.14 now report the installed 26.5.1, 9.0.1 and 3.14.7 as
current. flake8 exists only in ~/.venv and is now "not installed".

SonarCloud flagged S6547 (environment variable built from a value it treats as untrusted): the PATH for a catalog version_command started with the directory of the detected binary. The prefix is not needed. Without venv dirs, the tool name resolves to the same binary that find_paths selected, which is what the version_command test asserts.

"/venv/bin", "/.venv/bin" and "/env/bin" were matched as substrings of the normalized PATH entry, so /opt/venv/bin-extra/ counted as an environment and was skipped. The patterns now end with "/"; the normalized entry always ends with "/", so real environment bin dirs still match.

Review findings on the venv exclusion: - The deep-search tests set PATH to temp dirs only, so `which -a` itself was not found, the error was swallowed, and only the fast path ran. The tests now keep the directory of `which` on PATH; reverting the filtered PATH of the deep search makes two of them fail. - bulk.get_missing_tools and installer.validate_installation still used the plain PATH. A venv-only tool counted as installed for bulk installs while the audit reported it missing, and the post-install validation ran `<tool> --version` by name, i.e. the venv copy. Both now search the same PATH as the audit, and validation runs the binary it found. - With PATH unset, the filtered lookup returned no match instead of falling back to os.defpath like shutil.which does. - CHANGELOG names conda environments, which the same patterns exclude.

…py like the audit
Review round 2:
- reconcile skipped every binary whose real path lies in a directory
with a pyvenv.cfg next to bin/. uv tool and pipx install each tool
into such a venv, so detect_installations("black") returned [] for
the uv tool black. Per-tool venvs under uv/tools/ and pipx/venvs/
count as installations again.
- reconcile marked the active copy with a plain shutil.which, so with a
venv active no real installation was active. It uses the filtered
PATH now.
- _is_virtualenv_bin missed "~/env/bin/" (trailing slash): dirname
stayed inside bin/. The path is normalized first.
- CHANGELOG: version_commands run with the filtered PATH; the earlier
sentence described the removed prefix mechanism.

Review round 3: - With uv-tool and pipx installs now detected, classify_install_method ran its package-manager queries first. Those match the tool name as a substring of `cargo install --list`, `pipx list` or `uv tool list`, so a uv tool could be labelled pipx, and removal would run the wrong uninstaller. A binary inside a uv-tool or pipx per-tool venv is now classified by that directory before any query. - Relocated tool dirs (UV_TOOL_DIR, PIPX_HOME, PIPX_GLOBAL_HOME) are recognised, not only the default ~/.local/share/uv/tools and .../pipx/venvs. - "Preferred installation is not active" advised putting the manager's internal bin dir (~/.local/share/uv/tools/black/bin) first in PATH. It now names the PATH dir the binary was found in (~/.local/bin). - The reconcile test covers uv, pipx and a relocated uv tool dir.

… scope Review round 4: - A relocated UV_TOOL_DIR / PIPX_HOME / PIPX_GLOBAL_HOME was compared unresolved against a resolved binary path. With a symlink in the root (symlinked home, macOS /var) or a relative value the tool venv counted as an environment and the installation vanished from reconcile again. The root is resolved with realpath now. Reachable only since uv-tool and pipx installs are detected (before this PR reconcile skipped them, so it never removed them): - `uv tool uninstall` / `pipx uninstall` got the catalog name; catalog gam installs the gam7 package. They get the package name from the per-tool venv dir now. - A `pipx install --global` copy (PIPX_GLOBAL_HOME, default /opt/pipx) was uninstalled without --global, which removes the user-scope copy of the same package instead. - The broken-survivor message suggested "sudo uv install" / "sudo pipx install"; it names the manager's own install command.

…einstall hints Review round 5 (no correctness bug in the uninstall itself): - tool_manager_of matched any path below a tool root. It now requires <root>/<package>/bin, so a stray binary in <UV_TOOL_DIR>/bin is not taken for the package "<basename of UV_TOOL_DIR>". - PIPX_HOME / PIPX_GLOBAL_HOME / UV_TOOL_DIR are expanded (~) before they are resolved, as pipx reads them. - A global pipx venv is root-owned. As a normal user the removal is reported as "requires manual sudo: sudo pipx uninstall --global <pkg>" instead of running and failing, like apt/dnf/pacman removals. - The broken-survivor hint names what was removed: the uv/pipx package (gam7, not gam), --global with sudo for a global pipx copy, the cargo crate from the catalog (fd-find, git-delta), and brew without sudo. - A uv/pipx per-tool bin dir put on PATH directly was skipped as an environment; it is an installation.

Review round 6:
- Reconcile kept a uv/pipx per-tool bin dir that sits directly on PATH,
but the audit's filtered PATH still dropped it (every tool venv has a
pyvenv.cfg). The audit and bulk installs then reported the tool
missing, and reconcile marked it inactive. _is_environment_bin is now
the single rule ("venv, and not a tool manager's per-tool venv") for
_installation_path and both reconcile checks.
- Tool roots are resolved, so the rule resolves the dir too: a relocated
UV_TOOL_DIR reached through a symlink on PATH is kept.
- _catalog_meta skips non-dict available_methods entries instead of
losing all of the tool's catalog data to the exception.

Review round 7: - With a uv/pipx per-tool bin dir on PATH (directly, or put there by `uv tool run`), every executable in it counted as an installation of that tool's package, including its dependencies' entry points (pygmentize in httpie's venv). Aggressive reconcile of a catalog tool that is also a dependency could then run `uv tool uninstall <other tool>`. An executable in a per-tool venv now counts only if the manager's own record lists it: uv-receipt.toml [tool] entrypoints, pipx_metadata.json main_package.apps (plus injected packages installed with --include-apps). Audit lookups skip such executables and keep searching PATH; reconcile skips them. - Default tool roots that are themselves symlinks (~/.local/share/uv/tools -> /data/uvtools) are recognised by their resolved path, like relocated ones. - _catalog_meta also survives a non-dict "config" or a non-list available_methods. Checked on this machine: black, isort, gam (package gam7) and http (httpie) resolve to their uv tool venvs, and the audit differs from main only for black, isort, python@3.14 and flake8.

SonarCloud findings on the entry-point check: - tool_entrypoints built its path from bin_dir, which comes from PATH, and tried both record names in any directory (S8707, path traversal). It now resolves the manager first and opens only that manager's record name below its own tool root. - The cargo crate lookup moves out of _catalog_meta into _cargo_crate_of, which keeps the function under the complexity limit and also survives a non-list available_methods. - One test asserted two things in one statement.

Review findings on the entry-point check: - A catalog version_command runs the tool by name. It used the PATH that keeps a manager's per-tool venv, so a dependency's executable there could answer, and the standalone fallback could report a tool as installed when only a dependency copy exists. Such a command now runs with _command_path(), which drops every environment bin dir. - reconcile's active-copy lookup, bulk.get_missing_tools and installer.validate_installation called shutil.which with that same PATH and skipped the dependency check. All three use _which now. - An unreadable tool record made every executable in that venv count as a dependency without saying why; the path and the error are logged.

…name SonarCloud kept flagging tool_entrypoints for path injection: the file it opened was derived from a PATH entry, and the guard that constrained it lived in another function. _tool_venv_of resolves a bin dir once and returns (manager, root, package): the root is one of this machine's uv/pipx tool roots, and the package dir name must be a plain package name. tool_entrypoints then joins root, package and the manager's fixed record name, so nothing derived from PATH reaches open(). Tool roots now come from that list only (UV_TOOL_DIR, PIPX_HOME, PIPX_GLOBAL_HOME, XDG_DATA_HOME or ~/.local/share, ~/.local/pipx/venvs, /opt/pipx/venvs) instead of a "/uv/tools/" path fragment, so a venv that merely sits under a path containing that fragment no longer counts. The join is equivalent to the resolved path by construction; the validated package name is the part that decides, and a test covers it. Tests set the manager variables, because the roots are now per machine.

Review round 9: - `pipx install --include-deps <pkg>` links a dependency's apps on purpose and records them as apps_of_dependencies. They were treated as dependency copies, so such a tool (ansible-playbook) became "not installed" and a reinstall candidate. Those apps count now. - A symlink from an ordinary PATH dir into a venv (~/.local/bin/tool -> ~/proj/.venv/bin/tool) was rejected by reconcile but accepted by the audit. _is_foreign_binary now answers that question for both: the resolved dir is an environment, or the binary is a dependency copy in a tool venv. - The filtered PATH was rebuilt per lookup, and the filter stats every PATH entry. On this WSL host (128 entries, 37 of them /mnt/c) that was 42.7 ms per tool, about 5 s over a 117-tool audit. It is memoised on the PATH string, and _which asks once before walking the dirs: 2.9 ms per tool, about 0.34 s over 117 tools. - Tool roots also cover pipx's macOS home (platformdirs: ~/Library/Application Support/pipx), and XDG_DATA_HOME is expanded like the other variables. - _is_pipx_global resolves the path it compares, so a symlinked /opt still takes the sudo route.

A PATH entry can be a symlink to an environment's bin dir (~/current-bin -> ~/proj/.venv/bin). normpath does not follow it, so that dir stayed on the filtered PATH and a version_command could still resolve its tool to the venv copy. _is_virtualenv_bin resolves the dir first; the tool-venv exemption is unaffected, because it already compares resolved paths. Cost on this WSL host (128 PATH entries): the filtered PATH is built once per PATH value in 225 ms, then 0.07 ms per lookup — about 233 ms over a 117-tool audit.

…n copy Review round 10, no bug findings; these are the minor ones. - detect_installations split the raw PATH and filtered it entry by entry, so it paid the per-entry stats the memoised filter exists to avoid and kept a second copy of the rule. It uses _installation_path() now: same predicate, and the same PATH source _which already used, so with PATH unset both fall back to os.defpath where the listing used to find nothing. No test pins this; the cost is what moves. - The comment claiming _ENV_DIR_PATTERNS mirrors capability.sh was wrong: the shell side matches the unresolved path and skips every */venvs/*/bin, so it drops pipx per-tool venvs the Python side keeps. The comment says that instead of claiming a mirror. - _PACKAGE_DIR_RE also accepts "@", which pipx --suffix can put in a venv dir name (still no separator). - The rare fallback walk no longer re-scans the dir that already answered, and the filter predicate is no longer called "keep" while meaning the opposite.

## Summary After merge, `make upgrade` shows the real installed version of every multi-version runtime (`python@3.14`, `node@26`, `php@8.5`, …) from its first line on. Before, a runtime that had just been upgraded was offered for the same upgrade again, because the opening refresh kept its old version. - `make upgrade` opens with the network-free refresh `audit.py --update-local`. Its full-refresh path skipped every `tool@cycle` row with the comment "no per-cycle local-only data". - The merge path (the re-check after an install) already re-detected the cycles. That block becomes `_refresh_multi_version_entries`, and the full refresh calls it too. - Found while verifying #148: on the reporting machine `python@3.14` still read 3.14.0 with 3.14.7 installed. The full refresh works on copies of the cycle rows, so a row the detection does not reach (its runtime not in the tool list, or a failing detection) keeps its data unchanged. Cycle rows use the same directional status comparison as other tools, so a runtime newer than a stale stored version is not offered as an upgrade. A runtime whose detection fails is skipped with a message on stderr, in both paths, instead of aborting the refresh between writing the local state and the snapshot. Measured after the change on that machine: all 17 cycle rows match the installed versions; `python@3.14` reads 3.14.7 and UP-TO-DATE. The hooks lint and format whole files, so `audit.py` and `tests/test_update_fixes.py` were reformatted by black and isort, and one existing `E741` (`l` as a variable name) is renamed. The functional change is the helper and its second call site. ## Type of change - [x] Bug fix (`fix:`) ## Test plan - [x] `uv run pytest tests/ --ignore=tests/integration`: 862 passed, 1 skipped - [x] `uv run pytest tests/integration`: 10 passed - [x] `./scripts/test_smoke.sh`: exit 0 - [x] Eight new tests.

Summary
After merge, the audit ignores binaries inside a virtualenv or conda env and reports the real installation. On a machine with an always-activated
~/.venv, black, isort and python@3.14 stop showing as outdated after every successful upgrade.detection.find_paths, the multi-version lookup and catalogversion_commands searched the full PATH. An activated~/.venvput~/.venv/bin/black(25.11.0) ahead of the uv tool in~/.local/bin(26.5.1).make upgradeupgraded the uv tool, the re-audit found the venv copy again, and the tool stayed outdated.reconcile.pyandcapability.shalready skip environment bin dirs ("environments are not installations", PR fix(audit): exclude virtualenv binaries from reconcile, serialize prompts #110).

It also resolves the active copy through the filtered PATH, classifies a binary inside a uv-tool or pipx venv by that directory (the name-substring queries could name the wrong uninstaller), honoursUV_TOOL_DIR/PIPX_HOME/PIPX_GLOBAL_HOME, and its PATH advice names the PATH dir (~/.local/bin) instead of the manager's internal bin dir.uv tool uninstall/pipx uninstallget the package name from the venv dir (catalog gam installsgam7), a global pipx copy gets--global(as a normal user it is reported as "requires manual sudo" instead of run, like apt removals), and the broken-survivor hint names the removed package, crate and scope (uv tool install gam7,cargo install fd-find,sudo pipx install --global …) instead ofsudo uv install <tool>. The hint is tested through its helper, not through the removal flow. A tool venv is recognised only in the<root>/<package>/binlayout, and~in the manager variables is expanded.UV_TOOL_DIRworks).

A symlink from an ordinary PATH dir into a venv is no installation for the audit either, the same rule reconcile uses. The filtered PATH is memoised: on a WSL PATH with 128 entries a lookup costs 2.9 ms instead of 42.7 ms.
