Reject an empty 3rd field in the address parser by checking parts[2].Length > 0
before the All(char.IsDigit) guard, so a trailing-colon typo like "40001:F:"
produces a diagnostic instead of silently parsing as a scalar.

The DL205 family-native branch routed every V-prefixed address through
DirectLogicAddress.UserVMemoryToPdu, a plain octal-to-decimal decode.
DL205/DL260 system V-memory (V40400 and up) is not a simple octal decode:
the CPU relocates the system bank to Modbus PDU 0x2100. Octal-decoding
V40400 produced 16640 (0x4100), the wrong register, so any tag addressing
a system register through the grammar string silently read/wrote the
wrong PLC memory.
- Add DirectLogicAddress.VMemoryToPdu, which decodes the octal V-address,
detects the system bank (octal >= V40400 == SystemVMemoryOctalBase) and
relocates it through SystemVMemoryToPdu to PDU 0x2100; user-bank
addresses keep the plain octal decode.
- ModbusAddressParser's DL205 V branch now calls VMemoryToPdu instead of
UserVMemoryToPdu. UserVMemoryToPdu is retained for user-bank-only callers.
- Correct the ModbusFamilyParserTests V40400 assertion (16640 -> 0x2100)
and add system-bank regression cases plus direct helper coverage.

Reviewed all 31 src/ production projects against the 10-category
checklist in REVIEW-PROCESS.md. Each module gets its own findings.md;
code-reviews/README.md is regenerated from them.
334 findings: 6 Critical, 46 High, 126 Medium, 156 Low.
Critical findings:
- Server-001: WriteNodeIdUnknown recurses unconditionally — a HistoryRead
on an unresolvable node crashes the process (remote DoS).
- Admin-001/002: app-wide auth bypass (RouteView not AuthorizeRouteView)
plus unauthenticated mutating routes.
- Core.Scripting-001: System.Environment reachable from operator scripts;
Environment.Exit() terminates the server.
- Core.AlarmHistorian-001: rowIds/events parallel-list desync on a corrupt
payload misapplies outcomes — silent alarm-event data loss.
- Driver.Galaxy-001: ReconnectSupervisor is built but never triggered, so
a transient gateway drop permanently kills the event stream.
All findings are Status=Open; resolution is tracked per REVIEW-PROCESS.md
section 4. Review only — no source code changed.
