## v0.13.0 — 2026-05-01
### Fixed
- **SUB 5A bulk waveform stream — over-read bug for events ≥ 2 sec.**
`read_bulk_waveform_stream` was walking the chunk counter past the actual
end of the event, picking up post-event circular-buffer garbage that
corrupted reconstructed Blastware files for any waveform > ~1 sec. The
loop now extracts the event's `end_offset` from the STRT record at
`data[23:27]` of the probe response and stops the chunk walk when the next
counter would step past it. Verified against three BW MITM captures
(4-27-26 + 5-1-26): 2-sec event drops from 37 over-read chunks to 7
bounded chunks; 3-sec drops to 9; non-zero-start "event 2" drops to 9.
### Added
- `framing.bulk_waveform_term_v2(key4, end_offset, last_chunk_counter)` —
computes the corrected SUB 5A TERM frame's `(offset_word, params)` per the
formula confirmed across all 3 BW captures. Not yet wired into
`read_bulk_waveform_stream` (the legacy TERM is still used to preserve the
existing `blastware_file.write_blastware_file` frame-structure expectations);
available for the next iteration that switches to BW's 0x0200 chunk step.
- `framing.parse_strt_end_offset(a5_data)` — extracts the event-end pointer
from the STRT record in an A5 response payload.
Add read_bulk_waveform_stream() to MiniMateProtocol and wire it into
get_events() so each event gets authoritative client/operator/sensor_location
from the A5 frames recorded at event-time, not the current compliance config.
- framing.py: bulk_waveform_params() and bulk_waveform_term_params() helpers
(probe/chunk params and termination params for SUB 5A, confirmed from
1-2-26 BW TX capture)
- protocol.py: read_bulk_waveform_stream(key4, stop_after_metadata=True) —
probe + chunk loop (counter += 0x0400), early stop when b"Project:" found
(A5[7] of 9), then sends termination at offset=0x005A
- client.py: _decode_a5_metadata_into() needle-searches concatenated A5 frame
data for Project/Client/User Name/Seis Loc/Extended Notes; get_events() now
calls SUB 5A after each SUB 0C, overwriting project_info with event-time values
