95c7e0b490 Task #222 partial — unblock AB Legacy PCCC via cip-path workaround (5/5 stages)
Replaced the "ab_server PCCC upstream-broken" skip gate with the actual
root cause: libplctag's ab_server rejects empty CIP routing paths at the
unconnected-send layer before the PCCC dispatcher runs. Real SLC/
MicroLogix/PLC-5 hardware accepts empty paths (no backplane); ab_server
does not. With `/1,0` in place, N (Int16), F (Float32), and L (Int32)
file reads + writes round-trip cleanly across all three compose profiles.

## Fixture changes

- `AbLegacyServerFixture.cs`:
  - Drop `AB_LEGACY_TRUST_WIRE` env var + the reachable-but-untrusted
    skip branch. Fixture now only skips on TCP unreachability.
  - Add `AB_LEGACY_CIP_PATH` env var (default `1,0`) + expose `CipPath`
    property. Set `AB_LEGACY_CIP_PATH=` (empty) against real hardware.
  - Shorter skip messages on the `[AbLegacyFact]` / `[AbLegacyTheory]`
    attributes — one reason: endpoint not reachable.

- `AbLegacyReadSmokeTests.cs`:
  - Device URI built from `sim.CipPath` instead of hardcoded empty path.
  - New `AB_LEGACY_COMPOSE_PROFILE` env var filters the parametric
    theory to the running container's family. Only one container binds
    `:44818` at a time, so cross-family params would otherwise fail.
  - `Slc500_write_then_read_round_trip` skips cleanly when the running
    profile isn't `slc500`.

## E2E + seed + docs

- `scripts/e2e/test-ablegacy.ps1` — drop the `AB_LEGACY_TRUST_WIRE`
  skip gate; synopsis calls out the `/1,0` vs empty cip-path split
  between the Docker fixture and real hardware.
- `scripts/e2e/e2e-config.sample.json` — sample gateway flipped from
  the hardware placeholder (`192.168.1.10`) to the Docker fixture
  (`127.0.0.1/1,0`); comment rewritten.
- `scripts/e2e/README.md` — AB Legacy expected-matrix row goes from
  SKIP to PASS.
- `scripts/smoke/seed-ablegacy-smoke.sql` — default HostAddress points
  at the Docker fixture + header / footer text reflect the new state.
- `tests/.../Docker/README.md` — "Known limitations" section rewritten
  to describe the cip-path gate (not a dispatcher gap); env-var table
  picks up `AB_LEGACY_CIP_PATH` + `AB_LEGACY_COMPOSE_PROFILE`.
- `docs/drivers/AbLegacy-Test-Fixture.md` + `docs/drivers/README.md`
  + `docs/DriverClis.md` — flip status from blocked to functional;
  residual bit-file-write gap (B3:0/5 → 0x803D0000) documented.

## Residual gap

Bit-file writes (`B3:0/5` style) surface `0x803D0000` against
`ab_server --plc=SLC500`; bit reads work. Non-blocking for smoke
coverage — N/F/L round-trip is enough. Real hardware / RSEmulate 500
for bit-write fidelity. Documented in `Docker/README.md` §"Known
limitations" + the `AbLegacy-Test-Fixture.md` follow-ups list.

## Verified

- Full-solution build: 0 errors, 334 pre-existing warnings.
- Integration suite passes per-profile with
  `AB_LEGACY_COMPOSE_PROFILE=<slc500|micrologix|plc5>` + matching
  compose container up.
- All four non-hardware e2e scripts (Modbus / AB CIP / AB Legacy / S7)
  now 5/5 against the respective docker-compose fixtures.

6d290adb37 Task #220 — AB CIP + S7 live-boot verification (5/5 stages each)
Replicated the Modbus #218 bring-up against the AB CIP + S7 seeds to
confirm the factories + seeds shipped in #217 actually work end-to-end.
Both pass 5/5 e2e stages with `OpcUaServer:AnonymousRoles=[WriteOperate]`
(the #221 knob).

## AB CIP (against ab_server controllogix fixture, port 44818)

```
=== AB CIP e2e summary: 5/5 passed ===
[PASS] Probe
[PASS] Driver loopback
[PASS] Server bridge           (driver → server → client)
[PASS] OPC UA write bridge     (client → server → driver)
[PASS] Subscribe sees change
```

Server log: `DriverInstance abcip-smoke-drv (AbCip) registered +
initialized` ✓.

## S7 (against python-snap7 s7_1500 fixture, port 1102)

```
=== S7 e2e summary: 5/5 passed ===
[PASS] Probe
[PASS] Driver loopback
[PASS] Server bridge
[PASS] OPC UA write bridge
[PASS] Subscribe sees change
```

Server log: `DriverInstance s7-smoke-drv (S7) registered + initialized` ✓.

## Seed fixes so bring-up is idempotent

Live-boot exposed two seed-level papercuts when applying multiple
smoke seeds in sequence:

1. **SA credential collision.** `UX_ClusterNodeCredential_Value` is a
   unique index on `(Kind, Value) WHERE Enabled=1`, so `sa` can only
   bind to one node at a time. Each seed's DELETE block only dropped
   the credential tied to ITS node — seeding AbCip after Modbus blew
   up with `Cannot insert duplicate key` on the sa binding. Added a
   global `DELETE FROM dbo.ClusterNodeCredential WHERE Kind='SqlLogin'
   AND Value='sa'` before the per-cluster INSERTs. Production deployments
   using non-SA logins aren't affected.

2. **DashboardPort 5000 → 15050.** `HealthEndpointsHost` uses
   `HttpListener`, which rejects port 5000 on Windows without a
   `netsh http add urlacl` grant or admin rights. 15050 is unreserved
   + loopback-safe per the HealthEndpointsHost remarks. Applied to all
   four smoke seeds (Modbus was patched at runtime in #218; now baked
   into the seed).

## AB Legacy status

Not live-boot verified — ab_server PCCC dispatcher is upstream-broken
(#222). The factory + seed ship ready for hardware; the seed's DELETE
+ DashboardPort fixes land in this PR so when real SLC/MicroLogix/PLC-5
arrives the sql just applies.

## Closes #220

Umbrella #209 was already closed; #220 was the final child.

e8172f9452 Task #209 exit gate — seed-creds fix + live Modbus verification (4/5 stages)
Booted the server against the Modbus seed end-to-end to exercise the
factory wiring shipped in #216 + #217. Surfaced two real issues with
the seeds themselves; fixed both:

1. **Missing ClusterNodeCredential.** `sp_GetCurrentGenerationForCluster`
   enforces `ClusterNodeCredential.Value = SUSER_SNAME()` and aborts
   with `RAISERROR('Unauthorized: caller sa is not bound to NodeId')`.
   All four seed scripts now insert the binding row alongside the
   ClusterNode row. Without this, the server fails bootstrap with
   `BootstrapException: Central DB unreachable and no local cache
   available` (the Unauthorized error gets swallowed on top of the
   HTTP fallback path).

2. **Config cache gitignore.** Running the server from the repo root
   writes `config_cache.db` + `config_cache-log.db` next to the cwd,
   outside the existing `src/.../Server/config_cache.db` pattern. Add
   a `config_cache*.db` pattern so any future run location is covered.

## Verified live against Modbus

Booted server against `seed-modbus-smoke.sql` → pymodbus standard
fixture → ran `scripts/e2e/test-modbus.ps1 -BridgeNodeId "ns=2;s=HR200"`:

    === Modbus e2e summary: 4/5 passed ===
    [PASS] Probe
    [PASS] Driver loopback
    [PASS] Server bridge (driver → server → client)
    [FAIL] OPC UA write bridge (0x801F0000)
    [PASS] Subscribe sees change

The forward direction + subscription delivery are proven working through
the server. The reverse-write failure is a seed-or-ACL issue — server
log shows no exception on the write path, so the client-side status is
coming from the stack's type/ACL guards. Tracking as a follow-up issue
so the remaining three factory wirings can be smoke-booted against the
same pattern.

Note for future runs: two stale v1 `ZB.MOM.WW.LmxOpcUa.Host.exe`
processes from `C:\publish\lmxopcua\instance{1,2}\` squat on ports
4840 + 4841 on this dev box; kill them first or bump the seed's
DashboardPort.

7ba783de77 Tasks #211 #212 #213 — AbCip / S7 / AbLegacy server-side factories + seed SQL
Parent: #209. Follow-up to #210 (Modbus). Registers the remaining three
non-Galaxy driver factories so a Config DB `DriverType` in
{`AbCip`, `S7`, `AbLegacy`} actually boots a live driver instead of
being silently skipped by DriverInstanceBootstrapper.

Each factory follows the same shape as ModbusDriverFactoryExtensions +
the existing Galaxy + FOCAS patterns:
 - Static `Register(DriverFactoryRegistry)` entry point.
 - Internal `CreateInstance(driverInstanceId, driverConfigJson)` —
   deserialises a DTO, strict-parses enum fields (fail-fast with an
   explicit "expected one of" list), composes the driver's options object,
   returns a new driver.
 - DriverType keys: `"AbCip"`, `"S7"`, `"AbLegacy"` (case-insensitive at
   the registry layer).

DTO surfaces cover every option the respective driver's Options class
exposes — devices, tags, probe, timeouts, per-driver quirks
(AbCip `EnableControllerBrowse` / `EnableAlarmProjection`, S7 Rack/Slot/
CpuType, AbLegacy PlcFamily).

Seed SQL (mirrors `seed-modbus-smoke.sql` shape):
 - `seed-abcip-smoke.sql` — `abcip-smoke` cluster + ControlLogix device +
   `TestDINT:DInt` tag, pointing at the ab_server compose fixture
   (`ab://127.0.0.1:44818/1,0`).
 - `seed-s7-smoke.sql` — `s7-smoke` cluster + S71500 CPU + `DB1.DBW0:Int16`
   tag at the python-snap7 fixture (`127.0.0.1:1102`, non-priv port).
 - `seed-ablegacy-smoke.sql` — `ablegacy-smoke` cluster + SLC 500 + `N7:5`
   tag. Hardware-gated per #222; placeholder gateway to be replaced with
   real SLC/MicroLogix/PLC-5/RSEmulate before running.

Build plumbing:
 - Each driver project now ProjectReferences `Core` (was
   `Core.Abstractions`-only). `DriverFactoryRegistry` lives in `Core.Hosting`
   so the factory extensions can't compile without it. Matches the FOCAS +
   Galaxy.Proxy reference shape.
 - `Server.csproj` adds the three new driver ProjectReferences so Program.cs
   resolves the symbols at compile-time + ships the assemblies at runtime.

Full-solution build: 0 errors, 334 pre-existing xUnit1051 warnings only.

Live boot verification of all four (Modbus + these three) happens in the
exit-gate PR — factories + seeds are pre-conditions and are being
shipped first so the exit-gate PR can scope to "does the server publish
the expected NodeIds + does the e2e script pass."
