from pcapkit.protocols.data import * raises AttributeError (HOPOPT_QuickStartOption)

[JarryShaw]

A plain star-import of a public subpackage fails. Reproduced against 27bb315d5:

>>> from pcapkit.protocols.data import *
AttributeError: module 'pcapkit.protocols.data' has no attribute 'HOPOPT_QuickStartOption'

pcapkit/protocols/data/__init__.py:95 lists 'HOPOPT_QuickStartOption' in __all__, but the name is never bound:

'HOPOPT_QuickStartOption' in __all__ : True
hasattr(module, it)                  : False
IPv4_QuickStartRequestOption         : True
IPv6_Opts_QuickStartRequestOption    : True

Cause

Commit 1831bb60b (2023-03-06) split QuickStartOption into Request/Report variants in the child module. The parent's __all__ was updated for the IPv4_ and IPv6_Opts_ families but not the HOPOPT_ one.

Broken for ~3.5 years, which suggests nothing in CI star-imports this package.

Related omissions found in the same sweep

• pcapkit/protocols/schema/__init__.py.__all__ omits all 18 HOPOPT* names while listing all 18 IPv6_Opts* equivalents. Verified: hasattr(schema, 'HOPOPT') is True, 'HOPOPT' in schema.__all__ is False. git log -S HOPOPT on that file is empty — they were never added.
• 'ESP' is missing from both protocols.data.__all__ and protocols.schema.__all__ though present as an attribute in both, in both children, and in pcapkit.__all__ (from bdb7e5971, Implement ESP, with optional payload decryption #378). Also missing: 'Data', and 'Schema'/'EnumSchema'/'schema_final'.
• pcapkit/foundation/registry/__init__.py omits 6 functions that carry .. autofunction:: directives at docs/source/.../registry.rst:32-45.

Suggested fix

The one-word fix for the AttributeError, plus a guard test so the class cannot rot again — the house pattern already exists at tests/interface/test_core.py:238-251. A test that star-imports every public subpackage would have caught all of the above.
