First pass of test-suite reduction to address flaky CI and bloat.
Removed tests that fall into these change-detector patterns:
1. Source-grep tests (tests/gateway/test_feishu.py, test_email.py): tests
that call inspect.getsource() on production modules and grep for string
literals. Break on any refactor/rename even when behavior is correct.
2. Platform enum tautologies (every gateway/test_X.py): assertions like
`Platform.X.value == 'x'` duplicated across ~9 adapter test files.
3. Toolset/PLATFORM_HINTS/setup-wizard registry-presence checks: tests that
only verify a key exists in a dict. Data-layout tests, not behavior.
4. Argparse wiring tests (test_argparse_flag_propagation, test_subparser_routing
_fallback): tests that do parser.parse_args([...]) then assert args.field.
Tests Python's argparse, not our code.
5. Pure dispatch tests (test_plugins_cmd.TestPluginsCommandDispatch): patch
cmd_X, call plugins_command with matching action, assert mock called.
Tests the if/elif chain, not behavior.
6. Kwarg-to-mock verification (test_auxiliary_client ~45 tests,
test_web_tools_config, test_gemini_cloudcode, test_retaindb_plugin): tests
that mock the external API client, call our function, and assert exact
kwargs. Break on refactor even when behavior is preserved.
7. Schedule-internal "function-was-called" tests (acp/test_server scheduling
tests): tests that patch own helper method, then assert it was called.
Kept behavioral tests throughout: error paths (pytest.raises), security
tests (path traversal, SSRF, redaction), message alternation invariants,
provider API format conversion, streaming logic, memory contract, real
config load/merge tests.
Net reduction: 169 tests removed. 38 empty classes cleaned up.
Collected before: 12,522 tests
Collected after: 12,353 tests
When --yolo, -w, -s, -r, -c, and --pass-session-id exist on both the parent
parser and the 'chat' subparser with explicit defaults (default=False or
default=None), argparse's subparser initialization overwrites the parent's
parsed value. So 'hermes --yolo chat' silently drops --yolo, making it appear
broken.
Fix: use default=argparse.SUPPRESS on all duplicated arguments in the chat
subparser. SUPPRESS means 'don't set this attribute if the user didn't
explicitly provide it', so the parent parser's value survives through.
Affected flags: --yolo, --worktree/-w, --skills/-s, --pass-session-id,
--resume/-r, --continue/-c.
Adds 15 regression tests covering flag-before-subcommand, flag-after-subcommand,
no-subcommand, and env var propagation scenarios.
