Joseph Doherty 87e433871e docs: document inbound alarm ack/shelve (AlarmAck gate, alarm-commands, AdminUI/CLI) + remove scratch files
Records T17-T22 as shipped: RoleCarryingUserIdentity, Part 9 method handlers gated on AlarmAck
role, alarm-commands DPS topic, ScriptedAlarmHostActor dispatch, WriteAlarmCondition delta-gate,
AdminUI /alerts Acknowledge/Shelve/Unshelve buttons via AdminOperationsActor singleton, and
Client.CLI ack/confirm/shelve commands. Corrects stale "Not started" / "Partial" entries in
phase-7-status.md (Stream G OPC UA method binding row and C.6 row and Gap 1 body) and adds
the alarm-commands topic to Runtime.md. Removes untracked scratch files resume.md and pending.md.

Phase 3 PR 55 -- Mitsubishi MELSEC Modbus TCP quirks research document. 451-line doc at docs/v2/mitsubishi.md mirroring the docs/v2/dl205.md template for the MELSEC family (Q-series + QJ71MT91, L-series + LJ71MT91, iQ-R + RJ71EN71, iQ-R built-in Ethernet, iQ-F FX5U built-in, FX3U + FX3U-ENET / FX3U-ENET-P502, FX3GE built-in). Like Siemens S7, MELSEC Modbus is a patchwork of per-site-configured add-on modules rather than a fixed firmware stack, but the MELSEC-specific traps are different enough to warrant their own document. Key findings worth flagging for the PR 58+ implementation track: (1) MODULE NAMING TRAP -- QJ71MB91 is SERIAL RTU, not TCP. The Q-series TCP module is QJ71MT91. Driver docs + config UI should surface this clearly because the confusion costs operators hours when they try to connect to an RS-232 module via Ethernet. (2) NO CANONICAL MAPPING -- every MELSEC Modbus site has a unique 'Modbus Device Assignment Parameter' block of up to 16 assignments (each binding a MELSEC device range like D0..D1023 to a Modbus-address range); the driver must treat the mapping as runtime config, not device-family profile. (3) X/Y BASE DEPENDS ON FAMILY -- Q/L/iQ-R use HEX notation for X/Y (X20 = decimal 32), FX/iQ-F use OCTAL (X20 = decimal 16, same as DL260); iQ-F has a GX Works3 project toggle that can flip this. Single biggest off-by-N source in MELSEC driver code -- driver address helper must take a family selector. (4) Word order CDAB across Q/L/iQ-R/iQ-F by default (CPU-level, not module-level) -- no user-configurable swap on the server side. FX5U's SWAP instruction is for CLIENT mode only. Driver Mitsubishi profile default must be ByteOrder.WordSwap, matching DL260 but OPPOSITE of Siemens S7. (5) D-registers are BINARY by default (opposite of DL205's BCD-by-default). FNC 18 BCD / FNC 19 BIN instructions confirm binary-by-default in the ladder. Caller must explicitly opt-in to Bcd16/Bcd32 tags when the ladder stores BCD, same pattern as DL205 but the default is inverted. (6) FX5U FIRMWARE GATE -- needs firmware >= 1.060 for native Modbus TCP server; older firmware is client-only. Surface a clear capability error on connect. (7) FX3U PORT 502 SPLIT -- the standard FX3U-ENET cannot bind port 502 (lower port range restricted on the firmware); only FX3U-ENET-P502 can. FX3U-ENET-ADP has no Modbus at all and is a common operator mis-purchase -- driver should surface 'module does not support Modbus' as a distinct error, not 'connection refused'. (8) QJ71MT91 does NOT support FC22 (Mask Write) or FC23 (Read-Write Multiple). iQ-R and iQ-F do. Driver bulk-read optimization must gate on module capability. (9) MAX CONNECTIONS -- 16 simultaneous on Q/L/iQ-R, 8 on FX5U and FX3U-ENET. (10) STOP-mode writes -- configurable on Q/L/iQ-R/iQ-F (default = accept writes even in STOP), always rejected with exception 04 on FX3U-ENET. Per-model test differentiation section names the tests Mitsubishi_QJ71MT91_*, Mitsubishi_FX5U_*, Mitsubishi_FX3U_ENET_*, with a shared Mitsubishi_Common_* fixture for CDAB-word-order + binary-not-BCD + standard-exception-codes tests. 17 cited references including primary Mitsubishi manuals (SH-080446 for QJ71MT91, JY997D56101 for FX5, SH-081259 for iQ-R Ethernet, JY997D18101 for FX3U-ENET) plus Ignition / Kepware / Fernhill / HMS third-party driver release notes. Three unconfirmed rumours flagged explicitly: iQ-R RJ71EN71 early firmware rumoured ABCD word order (no primary source), QJ71MT91 firmware < 2010-05 FC15 odd-byte-count truncation (forum report only), FX3U-ENET firmware < 1.14 out-of-order TxId echoes under load (unreproducible on bench). Pure documentation PR -- no code, no tests. Per-quirk implementation lands in PRs 58+. Research conducted 2026-04-18.

Phase 2 PR 61 -- Close V1_ARCHIVE_STATUS.md; Phase 2 Streams D + E done. Purely a documentation-closure PR. The v1 archive deletion itself happened across earlier PRs: PR 2 on phase-2-stream-d archive-marked the four v1 projects (IsTestProject=false so dotnet test slnx bypassed them); Phase 3 PR 18 deleted the archived project source trees. What remained on disk was stale bin/obj residue from pre-deletion builds -- git never tracked those, so removing them from the working tree is cosmetic only (no source-file diff in this PR). What this PR actually changes: V1_ARCHIVE_STATUS.md is rewritten from 'Deletion plan (Phase 2 PR 3)' pre-work prose to a CLOSED retrospective that (a) lists all five v1 directories as deleted with check-marks (src/OtOpcUa.Host, src/Historian.Aveva, tests/Historian.Aveva.Tests, tests/Tests.v1Archive, tests/IntegrationTests), (b) names the parity-bar tests that now fill the role the 494 v1 tests originally held (Driver.Galaxy.E2E cross-FX subprocess parity + stability-findings regression, per-component *.Tests projects, Driver.Modbus.IntegrationTests, LiveStack/ smoke tests), and (c) gives the closure timeline connecting PR 2 -> Phase 3 PR 18 -> this PR 61. Also added the Modbus TCP driver family as parity coverage that didn't exist in v1 (DL205 + S7-1500 + Mitsubishi MELSEC via pymodbus sim). Stream D (retire legacy Host) has been effectively done since Phase 3 PR 18; Stream E (parity validation) is done since PR 2 landed the Driver.Galaxy.E2E project with HostSubprocessParityTests + HierarchyParityTests + StabilityFindingsRegressionTests. This PR exists to definitively close the two pending Phase 2 tasks on the task list and give future-me (or anyone picking up Phase 2 retrospectives) a single 'what actually happened' doc instead of a 'what we plan to do' prose that didn't match reality. dotnet build ZB.MOM.WW.OtOpcUa.slnx: 0 errors, 200 warnings (all xunit1051 cancellation-token analyzer advisories, unchanged from v2 tip). No test regressions -- no source code changed.
