The firmware path-len byte is packed and self-describing (src/Packet.h:79-84):
high 2 bits = hash size - 1, low 6 bits = hash COUNT (hops), byte length =
count * size. The app treated the low 6 bits as a byte count and ignored the
width, on the strength of a comment asserting the high bits were "not reliably
populated". Both halves of that comment were wrong.
Receive: Contact.fromFrame read `count` bytes where firmware meant `count`
hops, so at 2-byte width it kept HALF of every path and discarded the rest.
DAYTON VA's 2-hop route became a 2-byte fragment, which is why every repeater
login in Bandit's capture timed out.
Send: buildUpdateContactPathFrame wrote the count raw, leaving mode bits 00.
That tells the radio "1-byte hashes" while handing it 2-byte hash data, so it
routed to nodes never on the route. This is the likelier cause of the observed
"routes via c6 and 5c separately" behaviour.
Also fixes a third unit inconsistency: setContactPath wrote customPath.length
(bytes) into pathLength (hops) after every path set.
Contact now carries pathHashWidth per path, so a stored path can never be
re-sliced at a width it was not captured at. realHopCount() is removed rather
than adjusted: it divided an already-correct hop count, halving it at 2-byte
width, and every call site was compensating for a bug that no longer exists.
Migration (Ben's call, option A): records written before this change have no
pathHashWidth and hold truncated bytes that cannot be recovered by
reinterpretation, so their path is dropped and the contact reverts to flood
until the radio re-supplies it. Logged, not silent.
Tests asserted the old semantics (expect(realHopCount(2, 2), 1)) and were
rewritten against firmware truth rather than adjusted to keep passing. Added
send-side encoding coverage, which did not exist. 456 tests pass.

Every received DM/channel message now logs arrival wall-clock vs the
sender-claimed payload timestamp (delta + TIME ANOMALY marker beyond
24h), routed directly to AppDebugLogService so the rotating on-disk
trail is unconditional. Models persist a nullable rxTime set at every
live ingest construction site; legacy stored records stay null.
Diagnostic child of #280.

The firmware path-len byte packs a hash-mode hint in the high 2 bits and the
path byte-length in the low 6. Contact.fromFrame stored it raw, so a direct
node at 2-byte mode (0x40) read as pathLength 64: "64 hops" in the UI, a ~195s
ACK timeout, and up to 64 junk bytes pulled into contact.path that broke
repeater status/telemetry/neighbors until the path was cleared (#222).
- contact.dart: decode via pathHopCount (& 0x3F); keep 0xFF as the flood
sentinel; use the decoded length for safePathLen so path bytes stay clean.
- chat_screen _currentPathLabel: show realHopCount(pathLength, pathHashByteWidth)
so 2/3-byte nodes read the correct hop count; 0 -> Direct.
- Regression test for 0x40/0x00/0x03/0x44/0xFF; updated two model_changes tests
that codified the old raw mapping.
Part of #222 (stays open for on-hardware validation by the reporter).

Channel.toShareUri/fromShareUri/isValidShareUri encode the reference
MeshCore app's format: meshcore://channel/add?name=<url-encoded>&secret=<hex32>.
A "Share QR Code" action in the channel menu shows the QR via the existing
QrCodeShareDialog, so it round-trips with the reference app.
Encode/decode unit-tested against both real reference examples (#test, #echo).
Scan-to-add follows.

Consume the additive OCFG_BROKERS dump fields from firmware #172/#173
(backward-compatible — absent fields read as today's enabled/disabled):
- BrokerRuntimeState (`state`) + BrokerLastError (`last_error`) + a pure
BrokerConfig.status mapping -> Connected / Connecting / Failed (reason) /
Held (no clock|low heap) / Enabled / Disabled; held shown neutral, not error.
- Brokers list shows the real status line + colour instead of just "enabled".
- Editor shows jwt_owner / iata_override resolved defaults (`jwt_owner_resolved`,
`iata_resolved`) as greyed placeholders when the raw key is blank; only writes
the raw key when the user enters a value (blank stays the source of truth).
Sourced from the pool dump (getBrokers); getBroker's per-field GET list is
unchanged pending the firmware GET-ability answer on #173. Unit-tested mapping,
parsing, and backward-compat (9 tests).

A firmware build can ACK a broker enable/disable as success without applying it
(HV4; meshcore-firmware#179). The quick toggle and the editor save previously
trusted the ACK and showed a success snackbar, so an ack-but-no-op looked like
it worked.
Both paths now SET, wait a short settle, re-read the slot, and report what the
device ACTUALLY did:
- applied -> confirm
- notApplied -> warn "possible firmware issue"; the editor stays and re-seeds to
the device's true state instead of popping a false success
- unverified -> re-read failed (e.g. an enable that rebooted the device)
Every device is treated identically: the UI reflects the re-read, never assuming
a change took that the device didn't confirm.
- BrokerConfig.classifyApply pure classifier + BrokerApplyOutcome (unit-tested)
- ObserverConfigService.applySettleDelay
- wired into mqtt_brokers_screen quick toggle + broker_editor_screen save
- widget test for the ACK-but-not-applied path

The models are the existing draft (1983ed9); Gemini flagged nothing in them.
This pins the defensive behavior they give untrusted wire data: enum fromWire
fallback, numeric tryParse fallback, secret-presence flag, SecretField
three-state, copyWith. 7 tests, all green.
