v26 record index was a truncated u16 so it wrapped every ~18h — it's the same u32 every other version uses. v18's gravity gate was tighter than gen4's own and binned whole records, hr and rr with them, any time you were moving. skin temp was read unsigned so anything below 0c came out around +655. cadence read one byte of a u16. v21 always decoded 100 samples even when the block declared fewer, so a short buffer got stale bytes back as motion. command responses carry an echoed seq + status byte before the body, so body location, battery pack, get alarm and select wrist were all reading 2 bytes early — body location was reading the status byte as the location, which resolved to "wrist" on every successful reply. surfaced the status and gated the gen5 battery read on it, a failed read was handing back stale bytes as a real percentage. gen5 set/get clock need the leading revision byte or the rtc never latches, and the high-freq sync builders took no profile so they always framed gen4, which a gen5 strap can't parse at all. also moved the gen5 live imu decode in here from edge. it's the same record-21 buffer the historical path already decodes, just arriving as a live 0x2b frame instead, so they share one decoder now rather than two copies that can drift — and the live copy was reading the block capacity where the sample count lives, so its guard could never fail and it always decoded 100 samples even from a short buffer. cmdToggleImu takes a profile for the same reason the clock ones do. the response fixtures were built at the parser's own offsets so they passed either way — they now carry a real response header.

the r22 enable sequence was inverted. "2" means disable, not enable, so it was force-disabling the very packet flags it claims to turn on — and it also wrote hr_ch_switching and wear_detect_bias, which change the band's own hr and its on/off-body detection. these are permanent nvm writes and "0" is the only undo, so there's a restore-defaults sequence now too. dropped enable_sig12, that key doesn't exist. 0x99 (persistent optical save) is the one that leaves the led on and burns flash, and it wasn't in dangerousCmds — we were blocking its twin 0x9a instead and the comment blamed the wrong opcode. added it, plus forget-bonds and the read pointer. get body location and get battery pack info both sent an empty body, which reads as revision 0 and gets rejected, so neither has ever worked. the two config setters were short by 32 bytes and one had no revision byte at all. alarms: gen5 wants a 13th byte (crescendo, 0 or 1) and ids 1..6, gen4 keeps its hardware-verified 12 bytes and slot 0. get-alarm needs rev 4 + an id there. records: inner[2] isn't an opaque marker, bit 7 says the ppg rate is 25hz, so every record now reports its own rate. picked up the sub-second we were dropping, the two optical fields are one big-endian u16 each rather than four bytes, and the "unknown" f32 is the band's signal-quality variance. v20's unresolved warning comes off — the block metadata is led current and per-photo diode range/offset, which you need before amplitudes mean anything. added builders for the things we can't currently ask for at all: gyro enable/status, raw start/stop, adv name, config + flag read, ecg, event toggle. nothing calls them yet.

get clock never returned the clock. it scanned for the first u32 that looked
like an epoch and offset 1 always wins, so we've been reading
[status][sec b0..b2] instead of the field. it also only matched the gen4
opcode, so a gen5 reply decoded to nothing at all. reads the field now.
get data range could never have worked either — the scan stepped 4 bytes from
0 and both timestamps sit at 3 mod 4, so oldest/newest were never emitted.
same for the pages-behind block; the capacity==131072 gate went with it, that
constant came from the wrong offsets.
console logs dropped the first character of every chunk and invented a channel
byte that was actually that character. the reassembler's wrap mask was 16-bit
against an 8-bit counter, so every wrap read as a gap. battery-event charging
read a byte that's always zero.
the gen4 optical fields aren't what they're called: ppgRedIr is a u16 that
straddles the float32 at 32, skinContact is that float's sign+exponent byte
(hence only ever {0,63-70,194-198}), and skinTempRaw moves 5-10 counts a
second, which nothing thermal does. deprecated with the reason rather than
renamed — the app and the shipped db columns use these names. spo2 red/ir are
real bytes but move in lockstep with a fixed offset, so a ratio off them
follows one channel's drift.
0x28 carries no imu and was reporting activity 0 / steps 0; those are null now.
nine oracle cases move with it, same fix and same reasoning as 1e905b4 did for
the historical family. realtime rr capped at 4 on 0x28 — it has four slots and
counts above that were reading the wearing byte as a beat.
r10 is 100hz, so the step search only reaches 150-857 spm and walking sits
outside it. documented, not retuned — it finds nothing on any capture we have
and new constants would be just as unproven.

Dart operator precedence bitwise AND versus equality operator
💡 Result:
In Dart, the bitwise AND operator (&) has higher operator precedence than the equality operator (==) [1][2][3]. According to the official Dart documentation, precedence is structured such that bitwise AND, XOR, and OR operators are evaluated before relational and equality operators [1][2]. Specifically, the precedence hierarchy places bitwise AND (&) above relational and type test operators, which in turn are placed above equality operators (==,!=) [1][3]. Because of this precedence, an expression such as a & b == 0 is evaluated as (a & b) == 0 [1][2]. Using parentheses is recommended to improve code readability and explicitly define the intended order of operations [1][2].

Copy the raw tail before constructing R24.
These lines expose rawTail as the source for future re-decoding. If _parseV25 or _parseV24Layout passes a Uint8List.sublistView, later reuse of the input buffer changes _rawTailBytes. Lazy encoding can then return bytes that differ from the parse-time payload.
Make both parsers create an independent copy before passing rawTailBytes to R24.
Based on learnings: R24.rawTail must represent an immutable snapshot of the bytes supplied at parse time, and both parsers must copy the tail before creating R24.

Cache the parity corpus once instead of re-reading and re-decoding it per test.
_realV24Records and _real0x28Packets each call File('decode_parity_cases.json').readAsStringSync() and json.decode on every invocation. _realV24Records runs at lines 220, 228, 249, 257, and 274, and the R10 group parses the same file again at lines 292 and 320. The corpus holds at least 1887 v24 records plus the R10 records, so the suite decodes the full JSON at least seven times.
Hoist the parse into a lazily-initialized top-level value and derive both views from it.
♻️ Proposed refactor
+List<dynamic>? _casesCache;
+List<dynamic> _cases() => _casesCache ??=
+ json.decode(File('decode_parity_cases.json').readAsStringSync()) as List;

/// Every real v24 historical record in the parity corpus, as raw inner bytes.
-List<Uint8List> _realV24Records() {
- final cases =
- json.decode(File('decode_parity_cases.json').readAsStringSync()) as List;
- final out = <Uint8List>[];
+List<Uint8List>? _v24Cache;
+List<Uint8List> _realV24Records() {
+ if (_v24Cache != null) return _v24Cache!;
+ final cases = _cases();
+ final out = <Uint8List>[];
for (final c in cases) {
final hex = (c as Map)['hex'] as String;
if (hex.length != 192) continue;
final b = hexToBytes(hex);
if (b[1] == 24) out.add(b);
}
- return out;
+ return _v24Cache = out;
}
/// Every real 0x28 realtime packet in the parity corpus, as hex.
List<String> _real0x28Packets() {
- final cases =
- json.decode(File('decode_parity_cases.json').readAsStringSync()) as List;
return [
- for (final c in cases)
+ for (final c in _cases())
if (((c as Map)['hex'] as String).startsWith('28')) c['hex'] as String,
];
}Note that _realV24Records returns the same Uint8List instances after caching. The tests only read those bytes, so the shared buffers are safe here.

Restore the byte-order assertions for opticalBaseline, or move the comment.
Line 115 states the big-endian rule, and line 116 is now blank where the baseline assertions were. Only opticalAmp is checked against inner[100] and inner[101]. The baseline byte order is covered only by the literal 0x656F, so a swapped-half regression in the baseline field is harder to attribute.

all four were in builders nothing calls yet, so nothing shipped wrong — but they'd have been believed by whoever wired them first. get-alarm on gen5 range-checks the FIRST body byte as the slot id, so the [0x04][id] we were building read slot 4 and threw the real id away. the adv name field is 16 bytes and refuses a length over 15, not 31. the two ecg send commands read a two-byte word, so the second byte is a real on/off selector rather than padding. and the config/flag key-name reads are cursor iterators the count command resets — the index byte we were sending is never looked at. also put the persistent config writes behind dangerousCmds. the diff already described them as surviving a reboot with only a default-write to undo, which is the same argument the rest of that set is built on. the r22 sequence goes around the gate on purpose and ships its own restore path.

a few gen5 decode bugs, and one that turned out to be structural.
response bodies: a command response carries an echoed request seq + a status
byte before the body, so body location, battery pack, get alarm and select
wrist were all reading 2 bytes early. body location was reading the status
byte as the location, which comes out as "wrist" on every successful reply.
surfaced the status too and gated the gen5 battery read on it — a failed read
was handing back stale bytes as a real percentage.
records: v26's record index was truncated to a u16 so it wrapped every ~18h
(it's the same u32 as every other version). v18's gravity gate was tighter
than gen4's own and binned whole records, hr and rr included, any time you
were moving. skin temp was read unsigned so sub-zero came out around +655c.
cadence read one byte of a u16. v21 always decoded 100 samples even when the
block declared fewer, so a short buffer came back with stale bytes as motion.
commands: gen5 set/get clock need the leading revision byte or the rtc never
latches, and the high-freq sync builders took no profile so they always framed
gen4 — a gen5 strap can't parse that at all. cmdToggleImu takes a profile now
for the same reason.
live imu: pulled the gen5 live decode in here from edge. it's the same
record-21 buffer the historical path already decodes, just arriving as a live
0x2b frame, so both share one decoder now instead of two copies that drift.
the copy that was in edge read the block capacity where the sample count
lives, so its guard could never fail and it always decoded 100 samples even
from a short buffer.
the response fixtures were built at the parser's own offsets so they passed
either way. they carry a real response header now, and the live imu tests run
off a real captured frame.
no gen4 decode paths changed — parity suite is green.
