# Testing, Documentation & Underdeveloped Areas — Remediation Design & Implementation (2026-07-12 cycle)

Source review: [60-testing-docs-gaps.md](../60-testing-docs-gaps.md) · Baseline: `main` @ `4f5371f` · Generated: 2026-07-13

This cycle's new findings (TST-25..29) are all fallout or residue of the prior remediation: the Windows CI tier was removed after act_runner proved broken (TST-25), the docs describing that tier were not updated in the same commit (TST-26), a flag SEC-25 made live is still documented as dead (TST-27), a handshake field is asserted only on the side CI cannot run (TST-28), and the root-artifact triage from TST-14 needs its retirement decision refreshed (TST-29). Every citation below was re-verified against the working tree on 2026-07-13.

Prior-cycle open findings (TST-05..24 where still open) are tracked in the prior design doc, `archreview/remediation/60-testing-docs-gaps.md`; this doc covers only the new findings. Note TST-25 is the unlock for two of those: a working Windows tier is where the scheduled live-MXAccess smoke (old TST-05) and CI-run client wire tests (old TST-24) land.

## TST-25 — Windows/x86 test tier has zero automation   `High` · `P1` · Effort M

**Finding.** The `windows` and `live-mxaccess` CI jobs were removed in `abb0930` because Gitea act_runner v0.6.1 host-mode is broken on Windows and a `runs-on`-gated job with no matching runner wedges every run in "queued" (removal note: `.gitea/workflows/ci.yml:123-131`). Consequence: the x86/net48 Worker build, all of `src/ZB.MOM.WW.MxGateway.Worker.Tests` — including the tests for remediation-added machinery that exists nowhere else (`WorkerFrameWritePriority` ordering at `Worker.Tests/Ipc/WorkerFrameProtocolTests.cs:353-395`, worker-side `max_frame_bytes` adoption, WnWrap/subtag alarm consumers, `StaRuntime` changes) — and the 8-fact live suite (`src/ZB.MOM.WW.MxGateway.IntegrationTests/WorkerLiveMxAccessSmokeTests.cs`) run only when someone remembers the manual windev worktree process. The portable job's `check-codegen.ps1` Generated-diff check substitutes for the net48 CS0246 guard; nothing substitutes for actually compiling and running the worker tests.

**Impact.** A whole tier of *unit* tests — not just live smoke — is unguarded. A worker-side regression (frame priority inversion, frame-max adoption break, alarm-consumer conversion bug, STA loop change) ships green through CI and is caught, if at all, by hand on windev or in production. This regressed the prior cycle's TST-03/TST-05 posture and blocks old TST-24.

**Design.** Three candidates, weighed against the operational facts (Gitea Actions runs on a co-located `gitea-runner` container on docker host `10.100.0.35`, job containers on network `traefik` resolving `gitea:3000`; windev is Windows 10 at `10.100.0.48`, ssh alias `windev`, passwordless ssh from the Mac, MXAccess installed, and a proven isolated-worktree flow already exists in `C:\build` driven by remote PowerShell via base64 `-EncodedCommand`):

- **(a) Retry a Windows act_runner in host mode with the right labels — rejected.** The failure is not a label problem: act_runner v0.6.1's hostexecutor writes each step's script to a path it then cannot resolve (independent of shell) and cannot stage JS actions, so no label configuration fixes it; Windows containers are impractical for a net48/x86/MXAccess build. And the structural hazard remains: any `runs-on` gate with no live runner sticks queued forever, so a flaky/offline Windows runner would block *every* run. Revisit only if a fixed act_runner release ships — it would then replace the SSH job with a native one.
- **(b) SSH-driven job — recommended.** A Linux CI job (same `ubuntu-latest` runner class as `portable`, so it always schedules) ssh's to windev, fast-forwards an isolated CI clone under `C:\build` to the exact SHA under test, runs the x86 build + `Worker.Tests` there, and propagates the remote exit code through ssh → step → job. This reuses the already-proven windev worktree + `-EncodedCommand` recipe, requires no new runner software on Windows, and cannot wedge the queue (the Linux runner always exists; an unreachable windev fails the job red — loud, not stuck).
- **(c) Trigger split — adopted as part of (b).** Worker tests have nontrivial wall time on windev, and the live suite needs provider state and must never gate a push. Split: **per-push/PR** job runs `dotnet build Worker.csproj -p:Platform=x86` + `dotnet test Worker.Tests -p:Platform=x86` (unit suite — expected minutes; if measured wall time exceeds ~10 min, demote the test step to nightly and keep the per-push x86 build, which alone catches the net48/CS0246/x86 compile class); the **nightly** scheduled job (the existing `cron: '0 6 * * *'`, currently pointless) re-runs the x86 build + full Worker.Tests on `main`, then runs the live-MXAccess smoke with `MXGATEWAY_RUN_LIVE_MXACCESS_TESTS=1`, and optionally a full `src/ZB.MOM.WW.MxGateway.slnx` build (catches Windows-only analyzer diagnostics like xUnit1030 that never surface on macOS/Linux).

Design details for (b):

- **Isolation.** A dedicated CI clone `C:\build\mxaccessgw-ci` — never the Desktop checkout (dirty feature branch, per the established windev rule). The job's inline bootstrap (base64 `-EncodedCommand`) does `git fetch origin && git checkout --force <sha>` in that clone, then invokes the *checked-out* `scripts/ci/windev-worker-ci.ps1 -Sha <sha> -Mode <build|test|live>` so the CI logic itself is versioned with the code under test; only the tiny bootstrap lives in ci.yml.
- **Serialization.** One clone, potentially overlapping runs: `windev-worker-ci.ps1` acquires a lock (`New-Item C:\build\mxaccessgw-ci.lock -ItemType Directory`, retry loop with ~20 min timeout, always released in `finally`) so concurrent pushes queue instead of stomping the worktree. Add a workflow-level `concurrency` group too if the deployed Gitea version honors it — the lock is the guarantee, `concurrency` the nicety.
- **Secrets.** Generate a dedicated ed25519 keypair for CI (do **not** reuse the operator's personal windev key). Private key → Gitea Actions repo secret `WINDEV_SSH_KEY`; pinned host key → secret `WINDEV_SSH_KNOWN_HOSTS` (or a committed `scripts/ci/windev.known_hosts` — host keys are public data; committing is acceptable and greppable). The job writes the key to `~/.ssh/id_ed25519` mode 0600 and connects with `-o BatchMode=yes -o StrictHostKeyChecking=yes -o UserKnownHostsFile=...`. On windev, append the pub key to `authorized_keys` for the CI account; optionally prefix with a forced `command=` restricting it to the bootstrap script. Per CLAUDE.md, the key must never be echoed into logs.
- **Network precheck.** The job container is on the `traefik` docker network; confirm it has egress to `10.100.0.48:22` (a one-off `nc -z -w5 10.100.0.48 22` step during bring-up; docker bridge networks normally route to the LAN, but the network was created for gitea resolution, not egress, so verify rather than assume).
- **Failure visibility.** Per-push runs are first-class CI jobs — a red windev run is a red commit/PR check exactly like `portable`/`java`, and an unreachable windev **fails** (never skips) so a down Windows tier is loud. Nightly runs surface on the repo's Actions page against `main`; because nobody watches that page, add a final `if: failure()` step to the nightly job that opens (or comments on) a Gitea issue via the API using the built-in actions token, so a red nightly produces a notification artifact. Document in `docs/GatewayTesting.md` that a red `windows-x86` job means the Windows tier — not the change — may be down, and how to check (ssh windev, read `C:\build\mxaccessgw-ci\ci.log`).

**Implementation.**

1. **Windev prep (one-time, manual):** create `C:\build\mxaccessgw-ci` as a fresh clone of the Gitea origin (read-only deploy token or the existing credential store); verify `dotnet build src/ZB.MOM.WW.MxGateway.Worker/ZB.MOM.WW.MxGateway.Worker.csproj -p:Platform=x86` and `dotnet test src/ZB.MOM.WW.MxGateway.Worker.Tests/ZB.MOM.WW.MxGateway.Worker.Tests.csproj -p:Platform=x86` succeed there by hand; record wall time (drives the per-push vs nightly split for the test step). Generate the CI keypair, install the pub key on windev, store `WINDEV_SSH_KEY` (+ known-hosts) in Gitea repo secrets.
2. **New `scripts/ci/windev-worker-ci.ps1`** (runs *on windev*, invoked at the tested SHA): parameters `-Sha`, `-Mode build|test|live`; acquires/releases the lock dir; `build` = x86 Worker build; `test` = build + `dotnet test Worker.Tests -p:Platform=x86`; `live` = `test` + `MXGATEWAY_RUN_LIVE_MXACCESS_TESTS=1 dotnet test src/ZB.MOM.WW.MxGateway.IntegrationTests/... --filter FullyQualifiedName~WorkerLiveMxAccessSmokeTests` (+ optional full-slnx build); exits nonzero on any failure.
3. **New `scripts/ci/run-windev-ci.sh`** (runs *in the Linux job*): writes the key/known-hosts from env, builds the base64 `-EncodedCommand` bootstrap (fetch + checkout `$CI_SHA` in `C:\build\mxaccessgw-ci`, then `powershell -File scripts\ci\windev-worker-ci.ps1 -Sha $CI_SHA -Mode $1`), runs `ssh -o BatchMode=yes ci@10.100.0.48 ...`, exits with the ssh exit code. Do not wrap the remote git calls in `$ErrorActionPreference='Stop'` (git writes progress to stderr — known windev gotcha).
4. **ci.yml — add the per-push job** (same commit as steps 5–6):

   ```yaml
   windows-x86:
     # x86/net48 Worker build + Worker.Tests, executed on windev (10.100.0.48) over SSH.
     # Runs on a Linux runner so it always schedules (act_runner host-mode on Windows is
     # broken; a runs-on gate with no runner wedges the queue — see docs/GatewayTesting.md).
     runs-on: ubuntu-latest
     steps:
       - uses: actions/checkout@v4
       - name: Worker x86 build + tests on windev
         env:
           WINDEV_SSH_KEY: ${{ secrets.WINDEV_SSH_KEY }}
           WINDEV_SSH_KNOWN_HOSTS: ${{ secrets.WINDEV_SSH_KNOWN_HOSTS }}
           CI_SHA: ${{ github.sha }}
         run: ./scripts/ci/run-windev-ci.sh test   # demote to `build` if measured wall time > ~10 min
   ```

5. **ci.yml — add the nightly job** gated `if: github.event_name == 'schedule'` (safe: the gate is an `if`, not an unsatisfiable `runs-on`, so push runs mark it skipped, not queued), `runs-on: ubuntu-latest`, calling `run-windev-ci.sh live`; final `if: failure()` step posts a Gitea issue/comment via the API token. Fix the cron comment at `ci.yml:12-14` to describe what the schedule now actually runs.
6. **ci.yml — replace the removal note** at `:123-131` with a short pointer: host-mode act_runner remains broken; the Windows tier runs via the SSH-driven `windows-x86`/nightly jobs; restore native jobs only with a proven runner.
7. **TST-26 doc edits in the same commit** — see TST-26 below.
8. After the first green nightly, mark old **TST-05** addressed (live smoke is scheduled again) and unblock old **TST-24** (client wire tests can join CI).

**Verification.**
- Push a branch: `portable`, `java`, and `windows-x86` all green; confirm on windev that `C:\build\mxaccessgw-ci` sits at the pushed SHA.
- **Deliberate red:** on a scratch branch, add a failing `[Fact]` to `Worker.Tests` (or an intentional x86-only compile error), push, confirm `windows-x86` turns red and the run fails; revert. This proves exit-code propagation end-to-end, the whole point of the SSH design.
- **Unreachable-host red:** temporarily point the script at a bogus port (or stop sshd), confirm the job fails fast with a clear message rather than hanging or passing.
- **Concurrency:** push two branches back-to-back; confirm the second run's remote step waits on the lock and both complete.
- **Nightly:** temporarily set the cron a few minutes ahead (or trigger the schedule path manually), confirm the live job runs with `MXGATEWAY_RUN_LIVE_MXACCESS_TESTS=1` and, with a forced failure, that the on-failure issue step fires.
- Confirm no secret material appears in the job logs.

## TST-26 — Docs describe CI jobs that no longer exist   `Medium` · `P1 (folded into TST-25)` · Effort S

**Finding.** `docs/GatewayTesting.md:426-431` still documents the **`windows`** job ("the only host that builds the x86/net48 Worker… the definitive guard for the 'regenerate and commit `Generated/`' rule") and the **`live-mxaccess`** scheduled job — both deleted from `.gitea/workflows/ci.yml` in `abb0930`, which touched only the workflow file (a violation of the repo's docs-change-in-same-commit rule). Same stale claim at `scripts/check-codegen.ps1:17` ("guarded by the Windows CI job, not here") and in the `ci.yml:12-14` cron comment ("Nightly live-MXAccess smoke (windev)") though the schedule currently re-runs only `portable`+`java`.

**Impact.** Actively misleading in the worst direction: a reader concludes the worker build is CI-guarded when it is not, and the "definitive guard" claim is doubly wrong — the surviving guard for the Generated-commit rule is the portable job's `check-codegen.ps1` diff check, not a Windows compile.

**Design.** No standalone commit: these edits land **in the same commit as the TST-25 ci.yml change** (that is the same-commit rule the removal violated). Content rules: describe the jobs that exist (`portable`, `java`, `windows-x86`, nightly), name `check-codegen.ps1`'s Generated-diff check as the primary guard for the regenerate-and-commit rule with the windows-x86 net48 compile as the second line, and document the manual windev fallback (isolated `C:\build` worktree) as the degraded-mode procedure with its trigger condition (SSH job red for infra reasons). If TST-25 is somehow delayed, do **not** hold these edits hostage — an interim commit correcting the docs to the two-job reality plus a mandatory manual cadence (per-merge for worker-touching changes, weekly otherwise) is strictly better than the current false claim; rewrite again when the SSH job lands.

**Implementation.**
1. `docs/GatewayTesting.md:426-431` — replace the `windows` and `live-mxaccess` bullets with: `windows-x86` (SSH-driven, per-push, x86 build + Worker.Tests on windev; failure semantics — red job = tier or change broken, how to distinguish) and the nightly scheduled job (full Worker.Tests + live-MXAccess smoke, `MXGATEWAY_RUN_LIVE_MXACCESS_TESTS=1`, never gates a push, on-failure issue notification). Reword the paragraph at `:433-437` so the Generated/ guard attribution is: primary = `check-codegen.ps1` regeneration diff (portable job), secondary = net48 compile (windows-x86).
2. `scripts/check-codegen.ps1:17` — change "are guarded by the Windows CI job, not here" to "are guarded by the SSH-driven `windows-x86` CI job (see docs/GatewayTesting.md § Continuous Integration), not here".
3. `.gitea/workflows/ci.yml:12-14` — cron comment now describes the nightly windev run (covered by TST-25 step 5); `:123-131` removal note replaced (TST-25 step 6).

**Verification.** Greps prove the drift is gone: `grep -n '"windows"' docs/GatewayTesting.md` and `grep -n 'live-mxaccess' docs/GatewayTesting.md` return only descriptions of jobs that exist in `ci.yml`; `grep -n 'Windows CI job' scripts/check-codegen.ps1` returns the corrected text; `grep -rn 'definitive guard' docs/` attributes the Generated/ rule to `check-codegen.ps1`. Read the CI section back against the final `ci.yml` job list — every named job must exist, and every job in `ci.yml` must be named.

## TST-27 — `ShowTagValues` config row still says "Reserved"   `Medium` · `P1 (doc batch)` · Effort S

**Finding.** `docs/GatewayConfiguration.md:185` reads "Reserved display control for tag values. The dashboard does not show full tag values by default." — but SEC-25 wired the flag live: `src/ZB.MOM.WW.MxGateway.Server/Dashboard/Hubs/DashboardEventBroadcaster.cs:16-29` blanks tag values from the deep-cloned event before mirroring to SignalR when `Dashboard:ShowTagValues` is `false` (the default). `docs/GatewayDashboardDesign.md:170` was updated in the SEC-25 change; the authoritative config reference was not — remediation-created drift, same-commit rule violated.

**Impact.** An operator consulting the options table concludes toggling the flag does nothing, when it actually controls whether tag values reach **every** dashboard hub subscriber — security-relevant precisely because the per-session hub ACL (TST-15) does not exist yet: the redaction is currently the only thing between a low-trust Viewer and other sessions' tag values.

**Design.** Documentation-only correction of the one stale row; no code change. State three things in the row: (1) what `false` (default) does — tag values are blanked from the `MxEvent` copy mirrored to the SignalR events hub; metadata (tag reference, quality, status, timestamps) still renders; (2) the security relevance — with no per-session hub ACL yet (TST-15), `true` exposes all sessions' tag values to every authenticated dashboard viewer; (3) the honest scope limit — the flag gates only the hub mirror, **not** the `/browse` live-value display (the TST-16 residual, tracked separately; do not paper over it by implying full coverage). Ship in the cycle's P1 doc-drift batch (with WRK-26, CLI-42, SEC residuals per the 00-overall roadmap) — one commit for the batch is fine since each edit is independently verifiable.

**Implementation.**
1. `docs/GatewayConfiguration.md:185` — replace the row description with the three-part text above, cross-referencing `docs/GatewayDashboardDesign.md` for the mechanism.
2. While in the file, confirm the shape block's `"ShowTagValues": false` at `:60` needs no change (it doesn't — value and default are correct; only the prose row lies).
3. No edit to `DashboardEventBroadcaster.cs` or `GatewayDashboardDesign.md` (both already correct).

**Verification.** `grep -n 'Reserved' docs/GatewayConfiguration.md` no longer matches the `ShowTagValues` row; read the new row back against `DashboardEventBroadcaster.cs:16-29` (behavior), `Configuration/DashboardOptions.cs` (default `false`), and `GatewayDashboardDesign.md:170` (consistency). Confirm the row does **not** claim `/browse` coverage.

## TST-28 — Gateway-side `max_frame_bytes` untested in the CI-run suite   `Low` · `P2` · Effort S · relates IPC-02

**Finding.** `src/ZB.MOM.WW.MxGateway.Server/Workers/WorkerClient.cs:988` populates `MaxFrameBytes = (uint)_connection.FrameOptions.MaxMessageBytes` in the `GatewayHello` (wired from `Worker.MaxMessageBytes` via `Sessions/SessionWorkerClientFactory.cs:73-76`), but no test under `src/ZB.MOM.WW.MxGateway.Tests` references `MaxFrameBytes` at all. The adoption side is asserted only in `Worker.Tests` — Windows-only, i.e. inside the TST-25 gap.

**Impact.** A regression to sending `0` (which the worker deliberately treats as "older gateway, use default" per the IPC-02 negotiation contract) would pass every automated test while silently reverting the negotiated frame limit — an invisible downgrade of shipped IPC-02 behavior.

**Design.** One cheap fake-worker assertion; no new infrastructure needed. `FakeWorkerHarness.CompleteStartupAsync` already reads and **returns** the `GatewayHello` envelope (`Tests/Gateway/Workers/Fakes/FakeWorkerHarness.cs:149-165`), and `CreateConnectedPairAsync` already accepts a `maxMessageBytes` override that flows into the `WorkerFrameProtocolOptions` shared with the `WorkerClient` the harness creates — so the test is: start the client, complete the handshake, assert on the returned envelope. Cover both the default (`WorkerFrameProtocolOptions.DefaultMaxMessageBytes`) and an overridden value (e.g. `2 * 1024 * 1024`) as a `[Theory]`, which also pins that the field tracks configuration rather than a constant. Rejected alternative: asserting via the worker-side adoption tests only — that is exactly the Windows-only blind spot this finding names.

**Implementation.**
1. Add a `[Theory]` to `src/ZB.MOM.WW.MxGateway.Tests/Gateway/Workers/WorkerClientTests.cs` (natural home — its `CompleteHandshakeAsync` helper at `:26` already drives this path), e.g. `StartAsync_SendsGatewayHelloWithConfiguredMaxFrameBytes`: create the harness with `CreateConnectedPairAsync(maxMessageBytes: value)` for `value` ∈ {default, 2 MiB}, create/start the `WorkerClient`, capture the envelope from `CompleteStartupAsync`, assert `envelope.GatewayHello.MaxFrameBytes == (uint)value` (and `!= 0` for readability of intent).
2. No production code change; no doc change (`docs/WorkerFrameProtocol.md:25-30` already documents the negotiation).

**Verification.** `dotnet test src/ZB.MOM.WW.MxGateway.Tests/ZB.MOM.WW.MxGateway.Tests.csproj --filter FullyQualifiedName~WorkerClientTests` green on macOS/Linux (i.e. it runs in the `portable` CI job — the point of the finding). Mutation check while developing: temporarily hard-code `MaxFrameBytes = 0` in `WorkerClient.cs:988` and confirm the new test fails, then revert.

## TST-29 — Retire `oldtasks.md`; delete root docs-review artifacts   `Low` · `P2` · Effort S

**Finding.** TST-14's plan was "keep `oldtasks.md` only until the epic resumes, then delete", but TST-04 made it the durable governance record: `oldtasks.md:27-35,75-88` is now the only tracked statement that Phase 5 (orphan-worker reattach) is **deferred, not planned** and that `EnableOrphanReattach` (Task 26) "does not exist and must not be referenced". CLAUDE.md:79 links to it for exactly that statement. Meanwhile the mechanical half of TST-14 — deleting the five untracked, gitignored root working files (`MxAccessGateway-docs-{issues,fixed,final}.md`, `MxGatewayClient-docs-{issues,fixed}.md`, ~15k lines) — remains undone and keeps tripping greps.

**Impact.** Low, but real: deleting `oldtasks.md` naively would orphan a load-bearing governance record; keeping it forever contradicts its own "just a human-readable mirror" charter (`oldtasks.md:12-14`) and leaves two sources that can drift from `docs/plans/2026-06-15-session-resilience.md.tasks.json`. The untracked artifacts are pure grep noise.

**Design.** Move the durable decisions to where invariant-adjacent decisions live, then delete the mirror. `docs/DesignDecisions.md` gains a "Session-resilience epic scope" entry recording: Phase 5 deferred-not-planned with the rationale (reverses the "gateway restart does not reattach orphan workers" invariant; adoption-manifest store + phone-home protocol; deferred unless a concrete requirement appears); the explicit rule that `EnableOrphanReattach` does not exist and must not be referenced until its task lands; and the settled Phase-4 Viewer-default decision (admin-sees-all, Viewer strictly scoped to owned/granted sessions — `oldtasks.md:71-72`) so the TST-15 implementation doesn't have to rediscover it. The `tasks.json` remains the sole resume state for the still-pending Phase 4 tasks — one authority, no mirror. Do this now rather than waiting for the epic to close: the mirror's residual value (Task 14 Java remainder, Phase 4 checklist) is fully carried by `tasks.json` + the archreview register. Alternative rejected: keep `oldtasks.md` as the governance record — a file named "oldtasks" that must never be deleted is a trap for future cleanup passes.

**Implementation.**
1. `docs/DesignDecisions.md` — add the "Session-resilience epic scope" decision entry (content above, dated, citing the epic plan and TST-04).
2. Update the two tracked references before deletion: CLAUDE.md:79 ("see `oldtasks.md` (session-resilience epic Phase 5)" → point at `docs/DesignDecisions.md`); `stillpending.md:7,165` ("remaining epic tasks tracked in `oldtasks.md`" → point at `docs/plans/2026-06-15-session-resilience.md.tasks.json`). Leave `docs/plans/2026-06-16-stillpending-section8-design.md` (historical plan; a stale pointer in a dated plan is acceptable — optionally annotate).
3. `git rm oldtasks.md` — same commit as steps 1–2 (the record must never be absent from `main`).
4. `rm` the five untracked root files: `MxAccessGateway-docs-{issues,fixed,final}.md`, `MxGatewayClient-docs-{issues,fixed}.md` (gitignored at `.gitignore:152-154` — deletion is local-only, zero repo impact; no commit involved).
5. Do **not** touch `stillpending.md`'s own promote-or-migrate question, `REVIEW-PROCESS.md`, or `A2-galaxyrepository-adoption-handoff.md` — those remain TST-14's open triage in the prior-cycle doc.

**Verification.** `grep -rn 'oldtasks' --include='*.md' .` (excluding `archreview/`, which is a historical record) returns no tracked references; `grep -n 'EnableOrphanReattach\|deferred, not planned' docs/DesignDecisions.md` finds the migrated statements; `ls *-docs-*.md` at the repo root returns nothing; `git status` clean. Read CLAUDE.md:79 back to confirm the invariant sentence still holds and its pointer resolves.

## Cross-domain dependencies

- **TST-25 → old TST-05 / old TST-24:** the SSH-driven nightly is where the scheduled live-MXAccess smoke lands (closes old TST-05), and a working CI Windows tier unblocks wiring client wire-behavior tests into CI (old TST-24).
- **TST-25 ↔ IPC-24/IPC-25:** the nightly windev job is also the natural home for any Windows-side codegen verification the contracts/IPC remediation adds; coordinate job naming so both plans extend the same `windows-x86`/nightly jobs rather than adding parallel ones.
- **TST-26 ⊂ TST-25:** same commit, by rule.
- **TST-27:** ships in the cycle's P1 doc-drift batch alongside WRK-26 and CLI-42 (roadmap item 8); its `/browse` residual stays with TST-16 (prior cycle).
- **TST-28 ← IPC-02:** the test pins the gateway half of the IPC-02 negotiation; the worker half's tests become CI-run once TST-25 lands.
