Clears CommentChecker findings in src/ (3,280 -> 209, the remainder being false
positives like PLC-5/IEEE-754/M0.0) by adding missing summaries/params/returns,
normalising inheritdoc usage, and removing Gitea/review tracking IDs while keeping
the rationale they annotated. Comment-only: comment-stripped sources are identical
to the parent commit.
#572: listing continues at max(instance in page)+1 (no ascending-order assumption, no-progress guard kept);
browsePageDelayMs (default 5 ms) paces pages; DiscoverAsync reads templates through one batch reader
(IAbCipTemplateReaderFactory.CreateBatch) holding one lease.
#575: differential harness reports a same-status template refusal as an equal refusal; offline test pins the
open-attempt budget without relying on the abort ending the phase.

The old AdminUI cannot author the per-driver transport key (#576), so the
'pin before upgrading' recipe had no working path. A node-level appsetting
(env Drivers__AbCip__DefaultTransport) now supplies the default for AbCip
drivers with no key: explicit key > node default > compiled Native. Bound
and validated unconditionally (bad value fails host start); the driver
factory and the Test Connect probe both read it so they agree. AbCip.md
upgrade recipe rewritten around the key; Configuration.md documents it.
Also documents first-wins for AllowPacking/probe and host-alias throttles
(final review M6) and moves the status-bit note out of AbCip.md (M5).

- I1: the upgrade restart itself moves every no-key AbCip/AbLegacy driver to Native (every process
start constructs drivers, incl. boot-from-cache). Docs + CLAUDE.md now say so and tell operators
to set "transport": "Libplctag" BEFORE upgrading (older builds ignore the unknown key).
- I2: AbLegacy release note leads with the status-bit write refusal (T4:0.DN, C5:0.CU, R6:0.EN, ...)
on defaulted SLC/MicroLogix drivers and the fallback. The real client status is
BadCommunicationError, not BadNotSupported (the driver's write catch-all maps the runtime's
AbTransportException like any transport failure, as #571 does for PLC-5), with handle eviction
and Degraded health; pinned by a driver-level test (no 0xAA write on the wire, with a positive
control). ST string byte order stated as unverified. Also corrects the docs' "T4:0/DN" examples:
the driver's address grammar is "T4:0.DN" ("/DN" is a malformed address).
- I3: DriverProbeHandshakeE2eTests' two AbCip probe tests are a [Theory] over Native and
Libplctag. Run against ab_server controllogix: all 4 rows pass with identical exact messages.
- M1: documented (docs + resolver XML doc): the AdminUI merges only the probed device, so a
mixed-family defaulted AbLegacy driver can probe Native while running Libplctag.
- M2: factory ParseEnum rejects undefined integer strings ("7") via Enum.IsDefined (both drivers).
- M3: AbCip driver-level bad value reads "AB CIP config in '<id>' has unknown Transport ..."; the
named constant is gone (tagName: null now means driver-level).
- M4: the explicit-Native limited-family Warning is once per instance, not per (re)init.
- Nit: EffectiveTransport docs note that injected factories bypass it.

Task 22 (spec section 8 P5), with the controller rulings that exclude PLC-5 and LogixPccc.
- Transport is nullable on both option records; null (key absent) means "use the default" and is
never serialized. Factory DTO parse: absent -> null; a bad value still fails via ParseEnum.
- One resolver per driver (AbCipTransportResolver / AbLegacyTransportResolver), used by the driver
constructor, the Test Connect probe and (through the driver) the CLI.
AbCip: null -> Native. AbLegacy: null -> Native unless any device is Plc5 or LogixPccc, then the
whole driver resolves to Libplctag. Explicit values always win; explicit Native with a
Plc5/LogixPccc device logs one Warning at init.
- Init log shows configured vs effective, e.g. transport=Native (default).
- AdminUI forms: "Default (...)" / "Native (managed)" / "libplctag (fallback)". Default omits the
key on save (reverses Task 19's explicit re-emit, which would have pinned every edited driver).
- CLIs: --transport default|native|libplctag, default "default" via the resolver, so
--plc-type Plc5 with no --transport runs libplctag.
- Tests pinned to Libplctag where a default-path runtime was created: found by instrumenting the
native factories with the current xUnit test name (one unit test, AbLegacyReinitConfigAdoption;
plus the two fixture-gated AbCip probe E2E tests whose exact messages were proven on libplctag).
TransportMatrix and the differential harness already pass explicit transports.
- Switch/resolver/CLI/form tests are falsified by mutating the resolver (default -> Libplctag,
exclusion removed, AbLegacy default -> Libplctag): each mutation turns them red.
- Replaces the inline role-name literal in AbCipDriverFactoryExtensions' ParseEnum call with a named
constant; RoleAuthorityGuardTests was already red on the base commit for that line.
- Docs: AbCip.md / AbLegacy.md default + release note; CLAUDE.md AB section.

- AbCip/AbLegacy driver forms gain a Transport InputSelect; FromOptions/ToOptions now carry
Transport, so saving any other field no longer silently reverts Native to libplctag.
- Both drivers log the constructed transport once per init.
- AbCip factory now takes the host ILoggerFactory (it ran on NullLogger in production, hiding
every AbCip log line); DriverFactoryBootstrap passes it.
- Gate results: AdminUI /run (T19) native, inverted (dead port) and libplctag legs.
Apply the reviewed Modbus exemplar to the AbCip multi-device driver:
- Mapper AbCipEquipmentTagParser -> AbCipTagDefinitionFactory; TryParse -> FromTagConfig(tagConfig, rawPath, out def); drop leading-{ heuristic + the deviceHostAddress key; add inverse ToTagConfig; round-trip arrays/members/safety for coverage.
- Options: Tags (typed) -> RawTags (RawTagEntry list); Devices list kept.
- Driver: byName-only resolver over _tagsByRawPath (Ordinal); table built from RawTags via FromTagConfig, threading entry.DeviceName (device routing key) + entry.WriteIdempotent onto the def. Multi-device routing keys on DeviceName-or-host via a _devicesByRoutingKey index; discovery groups _declaredTags by RoutesToDevice.
- Factory: retire the pre-declared Tags DTO/BuildTag; bind List<RawTagEntry> RawTags.
- Probe: derive probe tag path from RawTags via the mapper.
- Cli BuildOptions projects typed tags -> RawTagEntry (ToTagConfig).
- Tests: AbCipRawTags helper (typed def -> RawTagEntry); parser tests -> FromTagConfig; blob-fallback driver tests rewritten to author via RawTags + read by RawPath. Driver.AbCip.Tests 342/342, Cli.Tests 42/42.
TODO(v3 WaveC): DeviceName becomes a pure logical name once the device connection host moves to the Device row's DeviceConfig.
Follow-ups from the fleet-wide read-timeout audit that the S7 R2-01 read-leg
fix (PR #453) prompted. The audit confirmed S7 was the ONLY driver with the
async-read-ignores-socket-timeout hang; these are the two adjacent (non-hang)
findings it surfaced.
1. FOCAS TimeoutMs:0 footgun (the risky one): a non-positive Timeout made
SynchronizedFocasClient DISABLE its per-call wall-clock ceiling, reverting to
the caller's long-lived poll token — reintroducing exactly the frozen-peer
wedge S7 just eliminated, under misconfig. Clamp non-positive TimeoutMs to the
2s default at the config boundary so the deadline can never be authored away.
2. TimeoutMs validation symmetry: apply the same clamp in the AbCip + AbLegacy
factories. libplctag's Tag.Timeout setter throws on <=0, faulting tag creation
on every read/write; clamping keeps a misconfigured TimeoutMs:0 running on the
default bound instead. (Shared PositiveTimeoutOrDefault helper per factory.)
3. AbLegacy reconnect parity with AbCip: AbLegacy evicted the cached libplctag
runtime on neither the non-zero-status nor transport-exception read/write path
(AbCip evicts on both), so a data-path fault recovered only via the probe loop
/ libplctag internals. Added EvictRuntime + wired it into both read and write
failure paths so a fresh handle is created on the next call.
Tests: FOCAS 265->269 (clamp theory + positive), AbCip 336->339 (clamp theory +
positive), AbLegacy 209->212 (read-nonzero / read-exception / write-nonzero evict).
No production regressions; all three driver suites green.
Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
Cross-module fix from the review sweep. -018 (Medium): AbCipTagDto/AbCipMemberDto dropped
elementCount/isArray, so driver-config-authored array tags read as a single scalar. Added the
two optional JSON fields (additive; missing -> scalar as before) threaded into the tag def +
TDD.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
- Driver.AbCip-007: inject an optional ILogger<AbCipDriver> /
ILogger<AbCipAlarmProjection> (default NullLogger) and log around
every read / write / template-fetch / probe / alarm-poll failure path.
- Driver.AbCip-011: LogWarning when InitializeAsync is configured with
Probe.Enabled=true but ProbeTagPath is blank — operators now see why
GetHostStatuses keeps reporting Unknown.
- Driver.AbCip-012: documented the LibplctagTemplateReader per-call
Tag cost as accepted given libplctag's own connection pool and the
low-frequency discovery use-case.
- Driver.AbCip-013: per-device AllowPacking + ConnectionSize overrides
on AbCipDeviceOptions, threaded through AbCipTagCreateParams; central
BuildCreateParams helper replaces five ad-hoc clones; AllowPacking
now reaches Tag.AllowPacking at runtime.
- Driver.AbCip-015: stale-comment sweep — every PR-N forward-reference
is rewritten to describe present behaviour.

Driver.AbCip-001 — ReinitializeAsync silently discarded its config JSON.
Extracted AbCipDriverFactoryExtensions.ParseOptions; InitializeAsync now
re-parses a content-bearing driverConfigJson and replaces _options (and
recreates the alarm projection), so a reinitialize with a changed config
(new device/tag, changed timeout) actually takes effect. A blank or
empty-object JSON keeps construction-time options for the unit-test seam.
Driver.AbCip-002 — libplctag status mapping used wrong integer constants.
MapLibplctagStatus now switches on the libplctag.NET Status enum members
(Ok/Pending/ErrorTimeout/ErrorNotFound/ErrorNotAllowed/ErrorOutOfBounds/…)
instead of hand-typed natives, so timeout/not-found/not-allowed/out-of-bounds
get their specific OPC UA codes instead of all collapsing to
BadCommunicationError. The int overload casts to Status to stay correct
against the wrapper's contiguous renumbering.
Driver.AbCip-003 — whole-UDT reads decoded members at declaration-order
offsets, which Studio 5000 does not guarantee. Added the opt-in
AbCipDriverOptions.EnableDeclarationOnlyUdtGrouping flag (default false);
AbCipUdtReadPlanner.Build forms no groups when it is off, so by default
every UDT member reads per-tag rather than at possibly-wrong offsets.
Driver.AbCip-008 — probe loops were fire-and-forget and ShutdownAsync raced
them. Each probe Task is stored on DeviceState.ProbeTask; ShutdownAsync now
cancels every CTS, awaits each probe Task (10s timeout), then disposes the
CTS and handles. DeviceState.Runtimes/ParentRuntimes are ConcurrentDictionary
and the Ensure*RuntimeAsync paths use TryAdd, disposing the losing concurrent
creator instead of leaking a native tag handle.
Adds AbCipDriverCodeReviewRegressionTests and updates existing AbCip tests
to the corrected status constants + opt-in grouping flag. AbCip driver +
test project build clean; all 244 AbCip tests pass. (The full-solution
build has pre-existing, unrelated Driver.Galaxy protobuf-generation errors
in this worktree.)

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
