has_artifacts counted only the paths a purge may remove. When all that was
left lay behind a linked dir, `purge claude <uuid>` (or auto) found no
adapter and exited 5 with an empty residual, hiding the path the purge
had refused to follow. has_artifacts now counts every candidate; _inside
still decides what is removed, so the CLI exits 0, removes nothing and
lists the linked path as residual.

_is_uuid took an uppercase or mixed-case uuid, and the paths built from it
are the live lowercase session's own files on macOS's default
case-insensitive APFS. The in-use checks compare exactly, though: session
files and command lines carry the lowercase id, so `purge claude <UPPER>`
found no holder and could remove a live session's files. _canonical now
lowercases a canonical uuid, and the paths, the session-file and job
matches, the in-use check and the residual all use it; a command line is
searched for both spellings.

json.load reads a huge integer as an int, and math.isfinite raised
OverflowError on it outside any try: conversation_in_use and purge_artifacts
(which must never raise) threw, where 6f4f40a had taken it as live. The
conversion to float now comes first, and an overflow means live.

The refusal pointed at ~/.claude/sessions/ for every agent, whatever
CLAUDE_CONFIG_DIR said, and never mentioned a non-agent process naming the
uuid on its command line. The in-use CLI now prints, on stderr while the
conversation is in use, the adapter's in_use_hints: for every adapter
`ps -axww | grep <uuid>`, and for claude its real sessions/ dir first. stop
prints them under its refusal, and says "records preserved" instead of
"no state was modified": the gate runs after the kill chain, so the session
itself may already be down. SKILL.md's exit 4 row says the same; it is not
a code block, so no inventory hash moves.

time.mktime read ps's local lstart, which is ambiguous in the hour a DST
change repeats: the start could come out an hour off and a live holder be
taken for a reused pid (or the reverse). ps now runs with TZ=UTC0, which BSD
ps and procps both honour, and calendar.timegm reads it. No /proc.

float("NaN") and a JSON NaN passed the old check, and every comparison with
NaN is false, so a live holder looked like a reused pid: the in-use gate let
the purge through and the session file was taken as stale. startedAt must
now be an int or float (not bool), finite and positive; anything else cannot
be told and counts as live. A dead pid is still stale whatever it says.

A tmp-root entry <key> linking outside made `<key>/<uuid>` look like a plain
directory, and rmtree removed what lay behind the link; projects/<key>,
file-history/ and the other config dirs had no such check either. Each
candidate now keeps the root it was found under (config, projects or tmp),
and is purged only when every component between that root and the leaf is a
real directory and its parent resolves inside the resolved root. A root may
itself be a link (/tmp -> /private/tmp), a leaf link is still removed as the
link alone, and a candidate behind a link is reported as residual instead.

projects/<key>/memory/ (Claude Code's auto memory) sits beside the session
dirs, and `purge claude memory` removed it whole. Only an 8-4-4-4-12 hex id
now reaches the session's directories, session files, jobs and tmp dirs. Any
other id keeps the pre-#31 reach, the `<id>.jsonl` file alone (test_a4 still
purges "uuid-c"); its residual is that file and nothing holds it in use.
The shared _plausible_id is unchanged for the other adapters.

The adapter's fixed /tmp fallback is now a module constant. The new tests
point it, TMPDIR, TMP and TEMP at the test's own dirs, in the test process
and (through a sitecustomize on PYTHONPATH) in every python a test starts,
so no test lists the real /tmp/claude-<uid> any more (Mac review, PR #59).

End to end through stop_session.sh with CLAUDE_CONFIG_DIR alone and with a
matching CLAUDE_PROJECT_DIR; plus the DiscoveryContext default. The
config-only stop case and the default check fail on 872d5f1.

Config-only and config+project overrides: a live session is refused and a
stopped one cleaned up. A key that cannot be removed keeps its session file;
a job dir that cannot be emptied keeps state.json; both are reported and
removed on retry. 5 of these fail on 8edb8d6.

17 of the 25 cases fail on 26e2c43; the other 8 pin invariants (other
sessions, shared files, malformed ids, a prefix-twin job dir).
