QA-owned boundary coverage for the frozen IF-LOC v1.0 codec, complementing
app-owner's nominal round-trip suite. Pins min/max/resolution limits per wire
field via the pure Encode/Decode seam, staying clear of the no-value sentinels,
and characterises the two sentinel-collision edges (depth -327.68 m, current
0xFFFF) so the contract's documented ranges are enforceable.
40/40 green; full QA gate green (app 43 + server 2). Trace: SRS §3.1, Risk R-3.

Reference implementation of the frozen IF-LOC v1.0 contract
(meta/contracts/ble-device-interface.md): byte-accurate codec for the
telemetry, capture-trigger, and capture-result frames, plus a
LocatorSimulator that replays a canned locate session over a
transport-agnostic loopback link. Unblocks App development without
firmware (Risk R-3, SRS S3.1).
Plain net9.0 (not a MAUI head) so it builds/runs headless under the QA
gate without the Android/iOS workloads; qa-gate.sh auto-discovers
*.Tests.csproj under app/tests/. Round-trip test asserts field-level
fidelity (every SRS S3.1 telemetry + capture-result field), sentinels,
endianness (incl. RFC 4122 big-endian pointId), the REJECTED path, and
exactly-once capture correlation (no silent drop, SRS-LOG-7). 8/8 green.

Standalone net9.0 xUnit project at tests/FieldLogger.Tests (no MAUI workload)
so `dotnet test` runs fast in the QA gate. Smoke suite only for now; real app
logic tests land once codec/sim are factored into a workload-free library.
Trace: SRS §6 gate, NFR-8.
