TST-24 asked for per-client wire tests against a fake gateway. An audit first
corrected the finding's premise: Go, Rust, and Java already had them — bufconn,
a loopback tonic server, and InProcessServerBuilder respectively — each already
asserting the round trip, the server-observed bearer header, and the ReplayGap
sentinel. The two genuine gaps were .NET (every test substituted the transport
interface; the test project had no server package at all) and Python (stub
monkeypatching everywhere but one opt-in TLS test).
Both now serve mxaccess_gateway.v1.MxAccessGateway over a real transport —
Kestrel h2c and grpc.aio, each on an ephemeral loopback port — and drive the
ordinary public client API against it. Only the gateway's behaviour is canned;
the framing, serialization, metadata, and status codes are genuine. Four shapes
each: full round trip with every reply field asserted, the authorization header
as received by the server (including on the streaming RPC), the ReplayGap
sentinel surfaced as the client's typed signal, and a real PERMISSION_DENIED
mapping to the typed authorization error.
The .NET client was only ever compiled in CI, never tested, so the portable job
gains a dotnet test step.
Fixes a bug the new tests caught on their first run: Python's connect() built the
grpc.aio channel inside asyncio.to_thread, and a grpc.aio channel binds to the
event loop current on the constructing thread, so every non-stub connection
raised 'There is no current event loop in thread'. No mock-based test could see
it, and the test guarding the off-loop behaviour patched create_channel and so
asserted the bug. Split resolve_channel_security (blocking TOFU probe, off-loop)
from create_channel (on-loop); the guard tests now assert both halves.
Doc half of TST-30 (single shared Gitea runner is a CI throughput/availability
bottleneck): docs/GatewayTesting.md's Continuous Integration section gains a
"Runner capacity is shared and finite" subsection covering the maxParallel=1
instance-level runner shared with dohertj2/lmxopcua, the ~20-30 min queue
latency observed under cross-repo contention, and Gitea 1.26's missing run
cancel/delete API. The existing "windev tier down" degraded-mode paragraph now
also covers "runner contended" as a reason to bypass the queue via
CI_SHA=<sha> scripts/ci/run-windev-ci.sh <mode> or the manual windev worktree
flow, generalizing it per the finding's design note.
New operator runbook docs/runbooks/TST-30-second-ci-runner.md carries the
actual runner registration (option a: second act_runner instance on
10.100.0.35 with the same container.network: traefik config, recommended;
option b: dedicated labelled runner, escalation only; option c: runner on
windev, rejected) plus verification steps and the no-cancel caveat. The
optional workflow-level concurrency group is documented as unverified --
framed as "verify before relying on it" -- and left unimplemented in ci.yml,
since registering the runner and any runs-on gating is operator/infra work
outside this repo's tree.
Tracking: TST-30 -> Done (doc half; runner registration operator-pending) in
both registers + change-log row.
TST-27: docs/GatewayConfiguration.md's ShowTagValues row no longer says
"Reserved" — it now states what false (default) does (DashboardEventBroadcaster
blanks tag values from a deep-cloned MxEvent before the SignalR events-hub
mirror), the security relevance (no per-session hub ACL yet, so this
redaction is the only thing between a low-trust Viewer and other sessions'
tag values), and the honest scope limit (does not cover /browse).
WRK-26 (discharges IPC-29): docs/MxAccessWorkerInstanceDesign.md's "Outbound
Queues" section rewritten from the stale five-level priority list to the
two-class Control/Event scheduler actually shipped, with the collapsed-
decision rationale, and the overflow paragraph rewritten to the implemented
fail-fast. docs/WorkerFrameProtocol.md gained a "Write Scheduling And
Sequencing" section describing HEAD truthfully: WRK-23's peek-stamp-commit
sequencing is live, WRK-25's event-batch flush coalescing is not (the drain
loop still awaits each event write individually), and WRK-22's cancellation
tombstone is not yet defined (noted as pending, not documented as shipped).
CLI-42: clients/rust/README.md and docs/ClientPackaging.md document the
vendored Rust proto layout matching build.rs — repo-path-first resolution
falling back to clients/rust/protos/, the check-codegen.ps1 Check 3 refresh
rule, and why cargo package/publish run without --no-verify.
CLI-43: docs/style-guides/JavaStyleGuide.md now says Java 17 (Ignition 8.3
baseline), mirroring CLI-12's wording, matching the shipped build.gradle.
IPC-28: docs/Grpc.md's exception-mapping prose gained CommandTooLarge ->
ResourceExhausted, and the Invoke section gained the oversized-payload
sentence, cross-referencing GatewayConfiguration.md's headroom rule.
Tracking: TST-27, WRK-26, CLI-42, CLI-43, IPC-28 flipped to Done and IPC-29
marked discharged-by-WRK-26 in 00-tracking.md and the 20/30/50/60 domain
registers, with a 2026-08-07 change-log entry.
Doc-only change; no source, proto, or test edits.
Flip the four findings to Done in the 2026-07-12 tracking registers
(Gateway core + Testing) and in the per-domain registers of
10-gateway-core.md and 60-testing-docs-gaps.md; append the 2026-08-07
change-log row recording what shipped, the pre-fix red for GWC-28, and
the TST-28 mutation check.
Migrate the durable session-resilience governance record (Phase 5
orphan-worker reattach deferred-not-planned, EnableOrphanReattach
does not yet exist, settled Phase-4 Viewer-default decision) from
oldtasks.md into a new "Session-Resilience Epic Scope" entry in
docs/DesignDecisions.md, repoint CLAUDE.md and stillpending.md's
oldtasks.md references to the new home / tasks.json, and git rm
oldtasks.md now that it has no unique content left. Flip TST-29 to
Done in the archreview tracking registers.
The five untracked root docs-review artifacts (MxAccessGateway-docs-*,
MxGatewayClient-docs-*) are absent from this worktree; they must be
deleted from the main working tree separately (gitignored, no repo
impact).
Surfaced during TST-25 acceptance verification: all CI runs on one shared
gitea-runner (maxParallel=1, co-located 10.100.0.35) interleaved with
dohertj2/lmxopcua, and Gitea 1.26 has no run cancel/delete API, so queue
latency is unbounded under cross-repo contention and the runner is a single
point of failure. Design: add a second/labelled runner; document the no-cancel
reality and the run-windev-ci.sh queue-bypass. Low/P2. Roll-ups updated.
Operator bring-up complete and the SSH-driven Windows/x86 CI tier passed
green end-to-end under Gitea Actions run #37: the Linux runner SSHed windev,
checked out the SHA in the isolated C:\build\mxaccessgw-ci clone under lock,
built the x86 Worker and ran Worker.Tests (exit 0); nightly-windev correctly
skipped on the push event. Flip TST-25/TST-26 status rows to Done and record
the bring-up + green-run evidence in the change log.
The `windows`/`live-mxaccess` CI jobs were removed in abb0930 because Gitea
act_runner host-mode on Windows is broken and a runs-on gate with no runner
wedges the queue. This left the entire x86/net48 Worker + Worker.Tests tier
(and the live-MXAccess smoke) unguarded by CI.
Restore it without a native Windows runner: Linux jobs on ubuntu-latest (which
always schedule) SSH to windev (10.100.0.48), fetch+checkout the SHA under test
in an isolated clone C:\build\mxaccessgw-ci, run the x86 build/tests there, and
propagate the remote exit code back — so a Worker regression turns the job red
and an unreachable host fails loud (never stuck).
- scripts/ci/run-windev-ci.sh: Linux driver (key/known-hosts, UTF-16LE base64
EncodedCommand bootstrap, ssh, exit-code passthrough).
- scripts/ci/windev-worker-ci.ps1: windev stage — worktree lock, re-fetch/
checkout under lock, build|test|live modes; PS 5.1-safe, checks $LASTEXITCODE.
- scripts/ci/windev.known_hosts: pinned host keys for StrictHostKeyChecking.
- scripts/ci/README.md: operator bring-up + acceptance checklist.
- ci.yml: windows-x86 (per-push `test`) + nightly-windev (scheduled `live` +
on-failure Gitea issue); drop the removal note; fix header/cron comments.
TST-26 (same commit, by rule): correct docs/scripts that still describe the
removed jobs — GatewayTesting.md, Contracts.md, check-codegen.ps1 — and
reattribute the Generated/-commit guard (primary = check-codegen diff in the
portable job; secondary = windows-x86 net48 compile).
Mechanism hand-verified on windev: build->0, bogus-SHA->nonzero (lock released),
test->356 passed/0 failed in ~50s, ssh exit-code propagation confirmed. Merge
requires operator bring-up first (dedicated ci@ key + Gitea secrets) or the
per-push job is red every push — see scripts/ci/README.md.
Six-domain re-review at the P2 merge (4f5371f): all prior Done claims
verified (none false, 10 partial), 47 new findings (1 High, 14 Medium),
with per-finding design/implementation plans and a new tracking register.
