Add data-path ACL design (acl-design.md, closes corrections B1) + dev-environment inventory and setup plan (dev-environment.md), and remove consumer cutover from OtOpcUa v2 scope.

ACL design defines NodePermissions bitmask flags covering Browse / Read / Subscribe / HistoryRead / WriteOperate / WriteTune / WriteConfigure / AlarmRead / AlarmAcknowledge / AlarmConfirm / AlarmShelve / MethodCall plus common bundles (ReadOnly / Operator / Engineer / Admin); 6-level scope hierarchy (Cluster / Namespace / UnsArea / UnsLine / Equipment / Tag) with default-deny + additive grants and Browse-implication on ancestors; per-LDAP-group grants in a new generation-versioned NodeAcl table edited via the same draft → diff → publish → rollback boundary as every other content table; per-session permission-trie evaluator with O(depth × group-count) cost cached for the lifetime of the session and rebuilt on generation-apply or LDAP group cache expiry; cluster-create workflow seeds a default ACL set matching the v1 LmxOpcUa LDAP-role-to-permission map for v1 → v2 consumer migration parity; Admin UI ACL tab with two views (by LDAP group, by scope), bulk-grant flow, and permission simulator that lets operators preview "as user X" effective permissions across the cluster's UNS tree before publishing; explicit Deny deferred to v2.1 since verbose grants suffice at v2.0 fleet sizes; only denied OPC UA operations are audit-logged (not allowed ones — would dwarf the audit log). Schema doc gains the NodeAcl table with cross-cluster invariant enforcement and same-generation FK validation; admin-ui.md gains the ACLs tab; phase-1 doc gains Task E.9 wiring this through Stream E plus a NodeAcl entry in Task B.1's DbContext list.

Dev-environment doc inventories every external resource the v2 build needs across two tiers per decision #99 — inner-loop (in-process simulators on developer machines: SQL Server local or container, GLAuth at C:\publish\glauth\, local dev Galaxy) and integration (one dedicated Windows host with Docker Desktop on WSL2 backend so TwinCAT XAR VM can run in Hyper-V alongside containerized oitc/modbus-server, plus WSL2-hosted Snap7 and ab_server, plus OPC Foundation reference server, plus FOCAS TestStub and FaultShim) — with concrete container images, ports, default dev credentials (clearly marked dev-only since production uses Integrated Security / gMSA per decision #46), bootstrap order for both tiers, network topology diagram, test data seed locations, and operational risks (TwinCAT trial expiry automation, Docker pricing, integration host SPOF mitigation, per-developer GLAuth config sync, Aveva license scoping that keeps Galaxy tests on developer machines and off the shared host).

Removes consumer cutover (ScadaBridge / Ignition / System Platform IO) from OtOpcUa v2 scope per decision #136 — owned by a separate integration / operations team, tracked in 3-year-plan handoff §"Rollout Posture" and corrections §C5; OtOpcUa team's scope ends at Phase 5. Updates implementation/overview.md phase index to drop the "6+" row and add an explicit "OUT of v2 scope" callout; updates phase-1 and phase-2 docs to reframe cutover as integration-team-owned rather than future-phase numbered.

Decisions #129–137 added: ACL model (#129), NodeAcl generation-versioned (#130), v1-compatibility seed (#131), denied-only audit logging (#132), two-tier dev environment (#133), Docker WSL2 backend for TwinCAT VM coexistence (#134), TwinCAT VM centrally managed / Galaxy on dev machines only (#135), cutover out of v2 scope (#136), dev credentials documented openly (#137).

    Search bar supports any of the five identifiers (ZTag, MachineCode, SAPID, EquipmentId, EquipmentUuid) — operator types and the search dispatches across all five with a typeahead that disambiguates ("Found in ZTag" / "Found in MachineCode" labels on each suggestion). Per-row click opens the Equipment Detail page.
 7. **Tags** — paged, filterable table of all tags. Filters: namespace kind, equipment (by ZTag/MachineCode/SAPID), driver, device, folder path, name pattern, data type. For Equipment-ns tags the path is shown as the full UNS path; for SystemPlatform-ns tags the v1-style `FolderPath/Name` is shown. Bulk operations toolbar: export to CSV, import from CSV (validated against active draft).

+8. **ACLs** — OPC UA client data-path authorization grants. Two views (toggle at top): "By LDAP group" (rows) and "By scope" (UNS tree with permission badges per node). Bulk-grant flow: pick group + permission bundle (`ReadOnly` / `Operator` / `Engineer` / `Admin`) or per-flag selection + scope (multi-select from tree or pattern), preview, confirm via draft. Permission simulator panel: enter username + LDAP groups → effective permission map across the cluster's UNS tree. Default seed on cluster creation maps v1 LmxOpcUa LDAP roles. Banner shows when this cluster's ACL set diverges from the seed. See `acl-design.md` for full design.

 The Drivers/Devices/Equipment/Tags tabs are **read-only views** of the published generation; editing is done in the dedicated draft editor to make the publish boundary explicit. The Namespaces tab and the UNS Structure tab follow the same hybrid pattern: navigation is read-only over the published generation, click-to-edit on any node opens the draft editor scoped to that node. **No table in v2.0 is edited outside the publish boundary** (revised after adversarial review finding #2).
