Problem: the crawler generated each member as 1 << offset in IANA's most-significant-first numbering, so FIN was 0x8000 and int() of a parsed SYN/ACK's connection was 0x4800 where the header carries 0x012. Fix: generate 1 << (15 - offset), each flag's mask in the 12-bit flags field, and narrow the range guard to 0 <= value <= 0xFFF. The const module is regenerated from the crawler. Tests and the dumpkit docstring that pinned the old integers, or used Flags for undeclared bits it no longer has, move to the new values or to BindingUpdateFlag. Test: test_const_tcp_flags_wire_masks_2310_unit checks every member's mask, composites, the guard, a parsed SYN/ACK, every flags octet reading back as itself with a byte-exact rebuild, and the crawler's output. Changelog entry under pcapkit.const, CHANGELOG.md regenerated.

Problem: of the 60 pull requests merged in the #2312-#2407 range, only #2334, #2336, #2337, #2340 and #2348 wrote a 1.5.0 changelog entry, and #2398 and #2403 only reworded lines that were already there. Every other user-visible change in the range -- wire-semantics fixes, maker guards, reassembly behaviour, public-API and error-message changes -- went unrecorded, so the entry no longer describes the release. Fix: one entry per user-visible pull request, in each module section's existing style and ordered by the issue it closes. Two pairs share a bullet, since each is the direct follow-up of the other: #2393 with #2401, and #2405 with #2407. The diff on the entry file is purely additive. Internal-only work is left out deliberately: dependency and action bumps (#2387 to #2391), test-only and docs-prose passes (#2333, #2376, #2379, #2380, #2402), the unreachable-branch removal (#2378), and the #: comment marker the HIP Group and Packet crawlers now write (#2381). That last one renders nothing either way: the marker lands inside the generated _missing_ body, conf.py's exclude-members drops _missing_ from autodoc, and a comment in a method body is not an attribute comment to begin with. #2392 and #2403 are recorded together, under Added rather than Fixed, for the declarations they introduce: __proto_key__ on the seven classes owning a __proto__ registry (#2392), __proto_dest__ on the four enum registries and Vendor.PROTO_DEST to generate it (#2403). Both PRs added the autodoc entries, so both are rendered public attributes. #2392's rejection-message change is deliberately not recorded as a fix: the bare "code must be ..." text it prefixed came from _check_code, which #2193 introduced and which is in no release tag -- absent at v1.5.0b14 -- so no released version ever emitted it. #2403 is no longer skipped as internal because it reworded an existing bullet to name __proto_dest__ while nothing credited the attribute's introduction. Four claims are corrected against the source rather than carried over: FTP_DATA shipped in pcapkit/protocols/application/ftp.py from 1.0.0, not 1.4.0 (class FTP_DATA(Raw) is there at v1.0.0); #2365's pre-fix fallback read cmmd.value, so a .value-carrying object was accepted unchecked rather than raising; #2399 left the dpkt adapter and the adapters' ModuleNotFound raises alone, so it claims no universal prefix; and #2397's old tail did name the version it got, so the entry quotes it and gains the :issue:`2302` it was missing. #2370's "a Section Header Block ... still fails" sentence is dropped: #2369 settles the byte order first, and an SHB built from raw octets with ctx=None now rebuilds byte-exact in both byte orders. CHANGELOG.md is regenerated with util/changelog_md.py. Test: tests/project/ in full, 0 failures, including test_changelog_md.py's in-step and supported-subset checks; util/changelog_md.py --check reports the two files in step; the entry parses under docutils with no structural warning.

fix — bug fixDescription
Closes #2310, per the ruling (take the recommendation). Breaking: every
tcp.flags.Flagsvalue changes.1 << offset, but IANA counts offsets from the high end of the 16-bit word. So FIN was0x8000, and a parsed SYN/ACK gaveint(connection) == 0x4800where the header carries0x12.1 << (15 - offset), so FIN is0x001and AE is0x100. The range checks narrow to the 12-bit field (0xFFF), andpcapkit/const/tcp/flags.pyis regenerated from the crawler. No library code depended on the old integers. The tests that pinned them, and therender_enumdocstring examples, are updated.test_const_tcp_flags_wire_masks_2310_unit.pychecks every wire mask, rejects0x1000, and covers a SYN/ACK whoseint(connection)equals the header bits. It also checks that all 256 flag-octet values rebuild byte-exact and thatmake()agrees with what it writes.origin/main, 302 failed, e.g.18432 != 18. On the head, 139 passed.connectionis built from the 8-bit flags byte, so AE and the reserved bits never appear in it. That predates this change.
