New/corrected sections:
§7.6.1 Record Time — corrected: anchor+10 supersedes the +0x28 absolute
offset. Added 3 s, 5 s, 8 s confirmations alongside existing 7/10/13.
Warning added: do NOT use fixed offset for BE11529.
§7.6.2 (NEW) SUB 1A Multi-Frame Read Protocol — 4-frame A/B/C/D
sequence documented (reverse-engineered from raw_bw capture). E5
page_key field explained. BE11529 duplicate-page behaviour and
(page_key, chunk_len) dedup strategy documented.
§7.6.3 (NEW) Sample Rate and DLE Jitter — Normal/Fast/Faster = 1024/
2048/4096 Sa/s confirmed. Root cause of ±1 byte cfg jitter explained:
4096 = 0x1000 → `10 10 00` in raw frame → `10 00` after DLE unstuffing
= 1 byte shorter than 04 00/08 00. Anchor search requirement explained.
Changelog — 5 new entries covering the 4-frame sequence, duplicate-page
detection, record_time anchor correction, sample_rate confirmation, and
_pending_frames / reset_parser=False implementation notes.
Quick Reference — Record Time and Sample Rate rows updated with correct
locations, types, and confirmed values.
Open Questions — SUB 1A item updated to "substantially resolved".
Record time item updated. Sample rate added as resolved.
