Joseph Doherty fdb268cee0 Docs + code-comment sweep — remove stale Pymodbus/ + PythonSnap7/ + LocateBinary references left behind by the native-fallback removal PR. Answer to "is the dev inventory + documentation updated": it was partial; this PR finishes the job. ...

Files touched — docs/drivers/Modbus-Test-Fixture.md dropped the key-files pointer at deleted Pymodbus/ + flipped "primary launcher is Docker, native fallback retained" framing to "Docker is the only supported launch path" (matching the code). docs/v2/dev-environment.md dropped the "skips both Docker + native-binary paths" parenthetical from AB_SERVER_ENDPOINT + flipped the "Native fallbacks" subsection to a one-liner that says Docker is the only supported path. docs/v2/modbus-test-plan.md rewrote §Harness from "pip install pymodbus + serve.ps1" setup pattern to "docker compose --profile <…> up" + updated the §PR 43 status bullet to point at Docker/profiles/. docs/v2/test-data-sources.md §"CI fixture (task #180)" rewrote the AB CIP section from "LocateBinary() picks binary off PATH" + GitHub Actions zip-download step to "Docker is the only supported reproducible build path" + docker compose GitHub Actions step; dropped the pinned-version SHA256 table + lock-file reference because the Dockerfile's LIBPLCTAG_TAG build-arg is the new pin.

Code docstrings + error messages — these are developer-facing operational text too. ModbusSimulatorFixture SkipReason strings (both branches) now point at `docker compose -f Docker/docker-compose.yml --profile standard up -d` instead of the deleted `Pymodbus\serve.ps1`; doc-comment at the top references Docker/docker-compose.yml. Snap7ServerFixture SkipReason strings + doc-comment point at Docker/docker-compose.yml instead of PythonSnap7/serve.ps1. S7_1500Profile.cs docstring updated. Modbus Dockerfile comment pointing at deleted tests/.../Pymodbus/README.md redirected to docs/drivers/Modbus-Test-Fixture.md. DL205Profile.cs + DL205StringQuirkTests.cs + S7_1500Profile.cs (in Modbus project) docstrings flipped from Pymodbus/*.json references to Docker/profiles/*.json.

Left untouched deliberately: docs/v2/implementation/exit-gate-phase-2-closed.md — that's a historical as-of-2026-04-18 snapshot documenting what was skipped at Phase 2 closure; rewriting would lose the date-stamped context. Its "oitc/modbus-server Docker container not started" + "ab_server binary not on PATH" lines describe the fixture landscape that existed at close time, not current operational guidance.

Final sweep confirms zero remaining `Pymodbus/` / `PythonSnap7/` / `LocateBinary` / `AbServerSeedTag` / `BuildCliArgs` / `AbServerPlcArg` mentions anywhere in tracked files outside that historical exit-gate doc. Whole-solution build still 0 errors.

Mitsubishi

Phase 3 PR 60 -- Mitsubishi MELSEC quirk integration tests against mitsubishi pymodbus profile. Seven facts in MitsubishiQuirkTests covering the quirks documented in docs/v2/mitsubishi.md that are testable end-to-end via pymodbus: (1) Mitsubishi_D0_fingerprint_reads_0x1234 -- MELSEC operators reserve D0 as a fingerprint word so Modbus clients can verify they're hitting the right Device Assignment block; test reads HR[0]=0x1234 via DRegisterToHolding('D0') helper. (2) Mitsubishi_Float32_CDAB_decodes_1_5f_from_D100 -- reads HR[100..101] with WordSwap AND BigEndian; asserts WordSwap==1.5f AND BigEndian!=1.5f, proving (a) MELSEC uses CDAB default same as DL260, (b) opposite of S7 ABCD, (c) driver flag is not a no-op. (3) Mitsubishi_D10_is_binary_not_BCD -- reads HR[10]=0x04D2 as Int16 and asserts value 1234 (binary decode), contrasting with DL205's BCD-by-default convention. (4) Mitsubishi_D10_as_BCD_throws_because_nibble_is_non_decimal -- reads same HR[10] as Bcd16 and asserts StatusCode != 0 because nibble 0xD fails BCD validation; proves the BCD decoder fails loud when the tag config is wrong rather than silently returning garbage. (5) Mitsubishi_QLiQR_X210_hex_maps_to_DI_528_reads_ON -- reads FC02 at the MelsecAddress.XInputToDiscrete('X210', Q_L_iQR)-resolved address (=528 decimal) and asserts ON; proves the hex-parsing path end-to-end. (6) Mitsubishi_family_trap_X20_differs_on_Q_vs_FX -- unit-level proof in the integration file so the headline family trap is visible to anyone filtering by Device=Mitsubishi. (7) Mitsubishi_M512_maps_to_coil_512_reads_ON -- reads FC01 at MRelayToCoil('M512')=512 (decimal) and asserts ON; proves the decimal M-relay path. Test fixture pattern: single MitsubishiQuirkTests class with a shared ShouldRun + NewDriverAsync helper rather than per-quirk classes (contrast with DL205's per-quirk splits). MELSEC per-model differentiation is handled by MelsecFamily enum on the helper rather than per-PR -- so one quirk file + one family enum covers Q/L/iQ-R/FX/iQ-F, and a new PLC family just adds an enum case instead of a new test class. 8/8 Mitsubishi integration tests pass (1 smoke + 7 quirk). 176/176 Modbus.Tests unit suite still green. S7 + DL205 integration tests can be run against their respective profiles by swapping MODBUS_SIM_PROFILE and restarting the pymodbus sim -- each family gates on its profile env var so no cross-family test pollution.

ZB.MOM.WW.OtOpcUa.Driver.Modbus.IntegrationTests.csproj

Remove native-launcher fallbacks for the four Dockerized fixtures — Docker is the only supported path for Modbus / S7 / AB CIP / OpcUaClient integration. Native paths stay in place only where Docker isn't compatible (Galaxy: MXAccess COM + Windows-only; TwinCAT: Beckhoff runtime vs Hyper-V; FOCAS: closed-source Fanuc Fwlib32.dll; AB Legacy: PCCC has no OSS simulator). Simplifies the fixture landscape + removes the "which path do I run" ambiguity; removes two full native-launcher directories + the AB CIP native-spawn path; removes the parallel profile-as-CLI-arg-builder code from AbServerFixture.
