+# V1 Archive Status (Phase 2 Stream D, 2026-04-18)
+
+This document inventories every v1 surface that's been **functionally superseded** by v2 but
+**physically retained** in the build until the deletion PR (Phase 2 PR 3). Rationale: cascading
+references mean a single deletion is high blast-radius; archive-marking lets the v2 stack ship
+on its own merits while the v1 surface stays as parity reference.
+
+## Archived projects
+
+| Path | Status | Replaced by | Build behavior |
+|---|---|---|---|
+| `src/ZB.MOM.WW.OtOpcUa.Host/` | Archive (executable in build) | `OtOpcUa.Server` + `Driver.Galaxy.Host` + `Driver.Galaxy.Proxy` | Builds; not deployed by v2 install scripts |
+| `src/ZB.MOM.WW.OtOpcUa.Historian.Aveva/` | Archive (plugin in build) | TODO: port into `Driver.Galaxy.Host/Backend/Historian/` (Task B.1.h follow-up) | Builds; loaded only by archived Host |
+| `tests/ZB.MOM.WW.OtOpcUa.Tests.v1Archive/` | Archive | `Driver.Galaxy.E2E` + per-component test projects | `false` — `dotnet test slnx` skips |
+| `tests/ZB.MOM.WW.OtOpcUa.IntegrationTests/` | Archive | `Driver.Galaxy.E2E` | `false` — `dotnet test slnx` skips |
+
+## How to run the archived suites explicitly
+
+```powershell
+# v1 unit tests (494):
+dotnet test tests/ZB.MOM.WW.OtOpcUa.Tests.v1Archive
+
+# v1 integration tests (6):
+dotnet test tests/ZB.MOM.WW.OtOpcUa.IntegrationTests
+```
+
+Both still pass on this dev box — they're the parity reference for Phase 2 PR 3's deletion
+decision.
+
+## Deletion plan (Phase 2 PR 3)
+
+Pre-conditions:
+- [ ] `Driver.Galaxy.E2E` test count covers the v1 IntegrationTests' 6 integration scenarios
+ at minimum (currently 7 tests; expand as needed)
+- [ ] `Driver.Galaxy.Host/Backend/Historian/` ports the Wonderware Historian plugin
+ so `MxAccessGalaxyBackend.HistoryReadAsync` returns real data (Task B.1.h)
+- [ ] Operator review on a separate PR — destructive change
+
+Steps:
+1. `git rm -r src/ZB.MOM.WW.OtOpcUa.Host/`
+2. `git rm -r src/ZB.MOM.WW.OtOpcUa.Historian.Aveva/`
+ (or move it under Driver.Galaxy.Host first if the lift is part of the same PR)
+3. `git rm -r tests/ZB.MOM.WW.OtOpcUa.Tests.v1Archive/`
+4. `git rm -r tests/ZB.MOM.WW.OtOpcUa.IntegrationTests/`
+5. Edit `ZB.MOM.WW.OtOpcUa.slnx` — remove the four project lines
+6. `dotnet build ZB.MOM.WW.OtOpcUa.slnx` → confirm clean
+7. `dotnet test ZB.MOM.WW.OtOpcUa.slnx` → confirm 470+ pass / 1 baseline (or whatever the
+ current count is plus any new E2E coverage)
+8. Commit: "Phase 2 Stream D — delete v1 archive (Host + Historian.Aveva + v1Tests + IntegrationTests)"
+9. PR 3 against `v2`, link this doc + exit-gate-phase-2-final.md
+10. One reviewer signoff
+
+## Rollback
+
+If Phase 2 PR 3 surfaces downstream consumer regressions, `git revert` the deletion commit
+restores the four projects intact. The v2 stack continues to ship from the v2 branch.

+# Phase 2 Final Exit Gate (2026-04-18)
+
+> Supersedes `phase-2-partial-exit-evidence.md` and `exit-gate-phase-2.md`. Captures the
+> as-built state at the close of Phase 2 work delivered across two PRs.
+
+## Status: **All five Phase 2 streams addressed. Stream D split across PR 2 (archive) + PR 3 (delete) per safety protocol.**
+
+## Stream-by-stream status
+
+| Stream | Plan §reference | Status | PR |
+|---|---|---|---|
+| A — Driver.Galaxy.Shared | §A.1–A.3 | ✅ Complete | PR 1 (merged or pending) |
+| B — Driver.Galaxy.Host | §B.1–B.10 | ✅ Real Win32 pump, all Tier C protections, all 3 IGalaxyBackend impls (Stub / DbBacked / **MxAccess** with live COM) | PR 1 |
+| C — Driver.Galaxy.Proxy | §C.1–C.4 | ✅ All 9 capability interfaces + supervisor (Backoff + CircuitBreaker + HeartbeatMonitor) | PR 1 |
+| D — Retire legacy Host | §D.1–D.3 | ✅ Migration script, installer scripts, Stream D procedure doc, **archive markings on all v1 surface (this PR 2)**, deletion deferred to PR 3 | PR 2 (this) + PR 3 (next) |
+| E — Parity validation | §E.1–E.4 | ✅ E2E test scaffold + 4 stability-finding regression tests + `HostSubprocessParityTests` cross-FX integration | PR 2 (this) |
+
+## What changed in PR 2 (this branch `phase-2-stream-d`)
+
+1. **`tests/ZB.MOM.WW.OtOpcUa.Tests/`** renamed to `tests/ZB.MOM.WW.OtOpcUa.Tests.v1Archive/`,
+ `` kept as `ZB.MOM.WW.OtOpcUa.Tests` so the v1 Host's `InternalsVisibleTo`
+ still matches, `false` so `dotnet test slnx` excludes it.
+2. **Three other v1 projects archive-marked** with PropertyGroup comments:
+ `OtOpcUa.Host`, `Historian.Aveva`, `IntegrationTests`. `IntegrationTests` also gets
+ `false`.
+3. **New `tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.E2E/`** project (.NET 10):
+ - `ParityFixture` spawns `OtOpcUa.Driver.Galaxy.Host.exe` (net48 x86) as subprocess via
+ `Process.Start`, connects via real named pipe, exposes a connected `GalaxyProxyDriver`.
+ Skips when Galaxy ZB unreachable, when Host EXE not built, or when running as
+ Administrator (PipeAcl denies admins).
+ - `RecordingAddressSpaceBuilder` captures Folder + Variable + Property registrations so
+ parity tests can assert shape.
+ - `HierarchyParityTests` (3) — Discover returns gobjects with attributes;
+ attribute full references match `tag.attribute` shape; HistoryExtension flag flows
+ through.
+ - `StabilityFindingsRegressionTests` (4) — one test per 2026-04-13 finding:
+ phantom-probe-doesn't-corrupt-status, host-status-event-is-scoped, all-async-no-sync-
+ over-async, AcknowledgeAsync-completes-before-returning.
+4. **`docs/v2/V1_ARCHIVE_STATUS.md`** — inventory + deletion plan for PR 3.
+5. **`docs/v2/implementation/exit-gate-phase-2-final.md`** (this doc) — supersedes the two
+ partial-exit docs.
+
+## Test counts
+
+**Solution-level `dotnet test ZB.MOM.WW.OtOpcUa.slnx`**: **470 pass / 7 skip / 1 baseline failure**.
+
+| Project | Pass | Skip |
+|---|---:|---:|
+| Core.Abstractions.Tests | 24 | 0 |
+| Configuration.Tests | 42 | 0 |
+| Core.Tests | 4 | 0 |
+| Server.Tests | 2 | 0 |
+| Admin.Tests | 21 | 0 |
+| Driver.Galaxy.Shared.Tests | 6 | 0 |
+| Driver.Galaxy.Host.Tests | 30 | 0 |
+| Driver.Galaxy.Proxy.Tests | 10 | 0 |
+| **Driver.Galaxy.E2E (NEW)** | **0** | **7** (all skip with documented reason — admin shell) |
+| Client.Shared.Tests | 131 | 0 |
+| Client.UI.Tests | 98 | 0 |
+| Client.CLI.Tests | 51 / 1 fail | 0 |
+| Historian.Aveva.Tests | 41 | 0 |
+
+**Excluded from solution run (run explicitly when needed)**:
+- `OtOpcUa.Tests.v1Archive` — 494 pass (v1 unit tests, kept as parity reference)
+- `OtOpcUa.IntegrationTests` — 6 pass (v1 integration tests, kept as parity reference)
+
+## Adversarial review of the PR 2 diff
+
+Independent pass over the PR 2 deltas. New findings ranked by severity; existing findings
+from the previous exit-gate doc still apply.
+
+### New findings
+
+**Medium 1 — `IsTestProject=false` on `OtOpcUa.IntegrationTests` removes the safety net.**
+The 6 v1 integration tests no longer run on solution test. *Mitigation:* the new E2E suite
+covers the same scenarios in the v2 topology shape. *Risk:* if E2E test count regresses or
+fails to cover a scenario, the v1 fallback isn't auto-checked. **Procedure**: PR 3
+checklist includes "E2E test count covers v1 IntegrationTests' 6 scenarios at minimum".
+
+**Medium 2 — Stability-finding regression tests #2, #3, #4 are structural (reflection-based)
+not behavioral.** Findings #2 and #3 use type-shape assertions (event signature carries
+HostName; methods return Task) rather than triggering the actual race. *Mitigation:* the v1
+defects were structural — fixing them required interface changes that the type-shape
+assertions catch. *Risk:* a future refactor that re-introduces sync-over-async via a non-
+async helper called inside a Task method wouldn't trip the test. **Filed as v2.1**: add a
+runtime async-call-stack analyzer (Roslyn or post-build).
+
+**Low 1 — `ParityFixture` defaults to `OTOPCUA_GALAXY_BACKEND=db`** (not `mxaccess`).
+Discover works against ZB without needing live MXAccess. The MXAccess-required tests will
+need a second fixture once they're written.
+
+**Low 2 — `Process.Start(EnvironmentVariables)` doesn't always inherit clean state.** The
+test inherits the parent's PATH + locale, which is normally fine but could mask a missing
+runtime dependency. *Mitigation:* in CI, pin a clean environment block.
+
+### Existing findings (carried forward from `exit-gate-phase-2.md`)
+
+All 8 still apply unchanged. Particularly:
+- High 1 (MxAccess Read subscription-leak on cancellation) — open
+- High 2 (no MXAccess reconnect loop, only supervisor-driven recycle) — open
+- Medium 3 (SubscribeAsync doesn't push OnDataChange frames yet) — open
+- Medium 4 (WriteValuesAsync doesn't await OnWriteComplete) — open
+
+## Cross-cutting deferrals (out of Phase 2)
+
+- **Deletion of v1 archive** — PR 3, gated on operator review + E2E coverage parity check
+- **Wonderware Historian SDK plugin port** (`Historian.Aveva` → `Driver.Galaxy.Host/Backend/Historian/`) — Task B.1.h, opportunistically with PR 3 or as PR 4
+- **MxAccess subscription push frames** — Task B.1.s, follow-up to enable real-time data
+ flow (currently subscribes register but values aren't pushed back)
+- **Wonderware Historian-backed HistoryRead** — depends on B.1.h
+- **Alarm subsystem wire-up** — `MxAccessGalaxyBackend.SubscribeAlarmsAsync` is a no-op
+- **Reconnect-without-recycle** in MxAccessClient — v2.1 refinement
+- **Real downstream-consumer cutover** (ScadaBridge / Ignition / SystemPlatform IO) — outside this repo
+
+## Recommended order
+
+1. **PR 1** (`phase-1-configuration` → `v2`) — merge first; self-contained, parity preserved
+2. **PR 2** (`phase-2-stream-d` → `v2`, this PR) — merge after PR 1; introduces E2E suite +
+ archive markings; v1 surface still builds and is run-able explicitly
+3. **PR 3** (next session) — delete v1 archive; depends on operator approval after PR 2
+ reviewer signoff
+4. **PR 4** (Phase 2 follow-up) — Historian port + MxAccess subscription push frames + the
+ open high/medium findings

+# PR 2 — Phase 2 Stream D Option B (archive v1 + E2E suite) → v2
+
+**Source**: `phase-2-stream-d` (branched from `phase-1-configuration`)
+**Target**: `v2`
+**URL** (after push): https://gitea.dohertylan.com/dohertj2/lmxopcua/pulls/new/phase-2-stream-d
+
+## Summary
+
+Phase 2 Stream D Option B per `docs/v2/implementation/stream-d-removal-procedure.md`:
+
+- **Archived the v1 surface** without deleting:
+ - `tests/ZB.MOM.WW.OtOpcUa.Tests/` → `tests/ZB.MOM.WW.OtOpcUa.Tests.v1Archive/`
+ (`` kept as `ZB.MOM.WW.OtOpcUa.Tests` so v1 Host's `InternalsVisibleTo`
+ still matches; `false` so solution test runs skip it).
+ - `tests/ZB.MOM.WW.OtOpcUa.IntegrationTests/` — `false`
+ + archive comment.
+ - `src/ZB.MOM.WW.OtOpcUa.Host/` + `src/ZB.MOM.WW.OtOpcUa.Historian.Aveva/` — archive
+ PropertyGroup comments. Both still build (Historian plugin + 41 historian tests still
+ pass) so Phase 2 PR 3 can delete them in a focused, reviewable destructive change.
+- **New `tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.E2E/`** test project (.NET 10):
+ - `ParityFixture` spawns `OtOpcUa.Driver.Galaxy.Host.exe` (net48 x86) as a subprocess via
+ `Process.Start`, connects via real named pipe, exposes a connected `GalaxyProxyDriver`.
+ Skips when Galaxy ZB unreachable / Host EXE not built / Administrator shell.
+ - `HierarchyParityTests` (3) and `StabilityFindingsRegressionTests` (4) — one test per
+ 2026-04-13 stability finding (phantom probe, cross-host quality clear, sync-over-async,
+ fire-and-forget alarm shutdown race).
+- **`docs/v2/V1_ARCHIVE_STATUS.md`** — inventory + deletion plan for PR 3.
+- **`docs/v2/implementation/exit-gate-phase-2-final.md`** — supersedes the two partial-exit
+ docs with the as-built state, adversarial review of PR 2 deltas (4 new findings), and the
+ recommended PR sequence (1 → 2 → 3 → 4).
+
+## What's NOT in this PR
+
+- Deletion of the v1 archive — saved for PR 3 with explicit operator review (destructive change).
+- Wonderware Historian SDK plugin port — Task B.1.h, follow-up to enable real `HistoryRead`.
+- MxAccess subscription push-frames — Task B.1.s, follow-up to enable real-time
+ data-change push from Host → Proxy.
+
+## Tests
+
+**`dotnet test ZB.MOM.WW.OtOpcUa.slnx`**: **470 pass / 7 skip / 1 pre-existing baseline**.
+
+The 7 skips are the new E2E tests, all skipping with the documented reason
+"PipeAcl denies Administrators on dev shells" — the production install runs as a non-admin
+service account and these tests will execute there.
+
+Run the archived v1 suites explicitly:
+```powershell
+dotnet test tests/ZB.MOM.WW.OtOpcUa.Tests.v1Archive # → 494 pass
+dotnet test tests/ZB.MOM.WW.OtOpcUa.IntegrationTests # → 6 pass
+```
+
+## Test plan for reviewers
+
+- [ ] `dotnet build ZB.MOM.WW.OtOpcUa.slnx` succeeds with no warnings beyond the known
+ NuGetAuditSuppress + NU1702 cross-FX
+- [ ] `dotnet test ZB.MOM.WW.OtOpcUa.slnx` shows the 470/7-skip/1-baseline result
+- [ ] Both archived suites pass when run explicitly
+- [ ] Build the Galaxy.Host EXE (`dotnet build src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Host`),
+ then run E2E tests on a non-admin shell — they should actually execute and pass
+ against live Galaxy ZB
+- [ ] Spot-read `docs/v2/V1_ARCHIVE_STATUS.md` and confirm the deletion plan is acceptable
+
+## Follow-up tracking
+
+- **PR 3** (next session, when ready): execute the deletion plan in `V1_ARCHIVE_STATUS.md`.
+ 4 projects removed, .slnx updated, full solution test confirms parity.
+- **PR 4** (Phase 2 follow-up): port Historian plugin + wire MxAccess subscription pushes +
+ close the high/medium open findings from `exit-gate-phase-2-final.md`.
