Cubic flagged that the original socket.create_connection probe matches any process on 9222/9223, not just Chrome. Mirror daemon.py's fallback by hitting /json/version, so a stale or unrelated listener does not skip the cloud bootstrap.
Drop the three boolean-table tests that mocked every collaborator and re-asserted the literal if-condition. Add a focused test for _local_chrome_listening that covers the false-positive case directly.
On headless servers (VPS, Docker) with no local Chrome, ensure_daemon() fires
before any user script runs and raises immediately — start_remote_daemon() can
never be reached from within a -c script.
Add a pre-check in main(): if no daemon is alive, Chrome is not listening on
known debugging ports (9222/9223), and BROWSER_USE_API_KEY is set, auto-
provision a Browser Use cloud browser before falling through to ensure_daemon().
_local_chrome_listening() probes ports 9222/9223 with a 0.3s timeout rather
than relying on _is_local_chrome_mode(), which only checks for absence of
BU_CDP_WS and would incorrectly trigger cloud bootstrap on a local machine
where Chrome is running but BROWSER_USE_API_KEY is also set (e.g. for profile
sync).
Fixes the behaviour reported in issues #181 and #183.
Tested on a headless Hostinger VPS running hermes-agent in Docker — browser-
harness -c '...' now works without any manual daemon setup when BROWSER_USE_API_KEY
is set.
When the browser dies but the daemon process keeps running, target_id and session stay cached on the Bridge. Pre-fix, connection_status swallowed the Target.getTargetInfo failure and returned the cached IDs with page=null, so admin counted the daemon as healthy. Now it returns {error: cdp_disconnected} and admin's existing error-check skips it. Also returns {error: not_attached} when target_id is unset.
When BH_TMP_DIR is set, the caller owns the directory and is expected to
give each daemon its own — so the bu-<NAME> filename prefix is redundant.
Dropping it cuts ~30 chars off the AF_UNIX path on POSIX, which matters
because sun_path is 104 bytes on macOS / 108 on Linux and a long BU_NAME
(e.g. an opencode-style session id) can blow past it.
Concretely the failing path on macOS for a 30-char session id under
~/.local/share/bcode/sessions/<sessionID>/bu-<sessionID>.sock was 117
bytes; with this change it becomes ~83 bytes.
When BH_TMP_DIR is unset, _TMP is the shared default (/tmp on POSIX,
gettempdir() on Windows) and the bu-<NAME> prefix is kept to disambiguate
multiple daemons sharing the dir. Backward compatible by default.
admin._daemon_endpoint_names: when BH_TMP_DIR is set, the dir is per-daemon
by construction, so glob discovery doesn't apply — just check whether our
local endpoint exists. Without BH_TMP_DIR, fall back to the existing
shared-dir glob.
Validation (_check on BU_NAME) still runs in both modes to catch garbage
names early.
Add browser_connections() / active_browser_connections() to admin, which probe
each daemon socket via a new connection_status meta message. The daemon tracks
target_id (set on attach and on set_session) and returns the live page title/URL
via Target.getTargetInfo. switch_tab now forwards target_id in set_session so the
daemon stays in sync after tab switches. run_doctor shows the count, each daemon
name, and the truncated active-page title and URL.

Replace naive `"return " in expression` check with a character-level parser that
ignores strings, line comments, and block comments. Add `_decode_unserializable_js_value`
to handle NaN, ±Infinity, -0, and BigInt. Extract `_runtime_value` and
`_runtime_evaluate` to unify error handling across `js()` and `page_info()`.
Wrap Runtime.evaluate TimeoutErrors in RuntimeError with expression context.

* refactor(tests): reorganize into tests/unit and tests/integration
Moves all root-level test_*.py files into a structured tests/ directory:
- tests/unit/ — admin, helpers (was test_screenshot), run
- tests/integration/ — js expression tests
- tests/conftest.py — shared fake_png pytest fixture, eliminating duplication

* refactor: move to src layout, agent-workspace, and fix SKILL.md invocation format
- Move package to src/browser_harness/ and domain-skills/interaction-skills to agent-workspace/
- Fix all browser-harness <<'PY' heredoc examples in SKILL.md and run.py HELP string to use the correct -c '...' flag format (heredoc was never supported by the CLI)
- Update SKILL.md path references from domain-skills/ to agent-workspace/domain-skills/
