Reserve the ACK following the next DCF fragment using its response mode. A production exchange at 54 Mbps with 24 Mbps ACKs now reserves the missing four microseconds. The focused module test and all four fragmentation fingerprints pass. Change: src.ieee80211.duration | behavior.change.fix | test | wifi-audit

Summary
A fragmented DCF frame reserved its next ACK at the data rate. Select the next fragment’s response ACK mode; the 54/24-Mbps case now reserves the additional four microseconds.
Scope
Originator protection mechanism; no configuration change.
Dependencies and merge order
No prerequisite within this audit series; this topic was built and tested independently on the pinned base.
Validation
Pinned test base:
7287f347aaca36e557c708d6930a6f5a450b2833.The isolated topic head passed an assertions-enabled debug build (
-O0 -Wall -g0; debug symbols omitted for storage) and the focused checks below. The larger integration source tree also passed debug and release compilation; no separate release build is claimed for this topic.Executed focused test commands, from the repository root after
source setenv -q:inet_run_module_tests -m debug -f 'Ieee80211FragmentAckDuration_1\.test'Results: 1 module cases passed.
Limits and review status
Independent of fractional Duration rounding.
Draft pending final independent review and reconciliation with current upstream. Live PR overlap has not been reverified against the pinned test base.
