+| 2026-08-17 | **Alarm-snapshot truncation now has a structural degraded-status signal** (branch `feat/deferred-closeout`, commits `693a78d` + `b9fb0dd`). No review ID — this is branch work outside the 153-finding register, recorded here so the tracker is not silent on a shipped change to the alarm surface. Before it, a capped `GetXmlCurrentAlarms2` fetch suppressed absence-implies-Clear inference and said so only in a rate-limited worker stderr warning, so no client and no operator could tell a complete active set from a capped one. Two additive proto3 booleans carry the verdict out — `QueryActiveAlarmsReplyPayload.snapshot_truncated = 2` and `ActiveAlarmSnapshot.from_truncated_snapshot = 16` (per record, because `QueryActiveAlarms` is a bare `stream ActiveAlarmSnapshot` with no envelope; the reply payload states it too, since a prefix filter can leave zero records and a capped fetch with nothing to report still has to say so). Flow: `WnWrapAlarmConsumer` → `AlarmDispatcher` / `IAlarmCommandHandler` → `MxAccessCommandExecutor` reply → `GatewayAlarmMonitor` → `IGatewayAlarmService.SnapshotTruncated` → `AlarmsPage` banner. `b9fb0dd` then made the pairing structural after review: `IMxAccessAlarmConsumer` and `IAlarmCommandHandler` expose one accessor (`SnapshotActiveAlarms(out bool truncated)` / `QueryActive(..., out bool snapshotTruncated)`) satisfied from a single lock acquisition, so the snapshot and its verdict can no longer be read across a poll; the separate `LastSnapshotTruncated` property is gone from every layer. Detection is deliberately unchanged (`fetchedRecordCount >= maxAlarmsPerFetch`); switching to `ALARM_RECORDS/@COUNT` stays blocked on probe evidence (`docs/AlarmProbeFindings.md`). Not latched, and dropped with the cache generation by `ClearCache`. Additive gateway metadata about our fetch mechanics, not MXAccess behaviour — no synthesized event, so not a parity deviation. Docs: `gateway.md` alarm surface, `docs/DesignDecisions.md`. |
 | 2026-08-17 | **TST-15 → `Done` (discharges the ACL half of SEC-25): per-session dashboard event ACL shipped** (branch `feat/deferred-closeout`, commits `693a78d` + `7ec0b35`). Implements `docs/plans/2026-07-10-dashboard-session-acl-tst15.md`, whose header is now `Implemented` with as-built notes in its §12. `IDashboardSessionAcl.CanViewSession` is the single decision **both** subscribe seams consult — `EventsHub.SubscribeSession` (denial is a `HubException`; the caller is neither joined to the group nor registered in `EventsHubViewerRegistry`, so the mirror stays off) and `SessionDetailsPage`'s in-process subscribe (inline denial, no subscription) — so neither path is the weaker one and the `TODO(per-session-acl)` is gone. Decision order, fail-closed on every branch: authenticated Administrator → allow (evaluated **before** the registry lookup, so Admin × unknown-session allows — pinned by a test because reordering the two checks is a plausible refactor); session not found → deny; untagged session → `Dashboard:UntaggedSessionVisibility` (`AdminOnly` default); else allow iff `session.Tags ∩ zb:dashboardtag` claims, ordinal-ignore-case. Session tags are inherited from the owning API key's `dashboard_tags` constraint (`apikey --dashboard-tags`, already in the `ApiKeyConstraints` JSON blob — no SQLite migration) and never from the client's wire request. Viewer grants come from `Dashboard:GroupToTag` over the user's LDAP groups, stamped at cookie login (`DashboardAuthenticator.CreatePrincipal`) and **re-resolved, not copied**, at hub-token mint (`HubTokenService.Issue`), so the 5-minute token lifetime bounds a stale grant. Anonymous localhost is an empty-grant Viewer; `Dashboard:DisableLogin` auto-login carries both roles and so takes the admin bypass unchanged. Tests: `DashboardSessionAclTests` (decision table, every branch asserted in its denying direction too), `EventsHubTests`, `DashboardAuthenticatorTests`, `HubTokenServiceTests`, a `GatewayOptionsTests` case proving `Dashboard:GroupToTag` keeps its ordinal-ignore-case lookup through configuration binding, and two `[LiveLdapFact]`s in `DashboardLdapLiveTests` that drive a real bind against the shared GLAuth (`gw-viewer` → `team-a` grant admits the `team-a` session and refuses the `team-b` one; `multi-role` bypasses on the sessions its own grant does not cover). The live pair needed **no GLAuth change** — the tag layer is config-side, keyed on the existing `GwAdmin`/`GwReader` groups (recorded in `glauth.md`). Docs: `docs/Sessions.md` (session-tag model), `gateway.md` + CLAUDE.md dashboard-auth paragraphs, `docs/GatewayDashboardDesign.md` (three passages that described the ACL as outstanding), `docs/GatewayConfiguration.md` (`ShowTagValues` row: redaction is now the second of two layers, not the only one), `docs/Authentication.md` (`--dashboard-tags` is the only *constraint* flag that splits on commas). |
 | 2026-08-10 | **TST-25 acceptance Check 6 (forced-failure nightly issue) → Done.** The 2026-07-13 record wrote this check off as "abandoned to shared-runner congestion"; that was wrong on both counts. The 2026-07-13 probe *did* land (issue #125, `[CHECK6 PROBE]`, run 375), and since 2026-07-17 the `nightly-windev` `if: failure()` step has filed an issue on **every** red nightly — #126–#139, all authored by the `gitea-actions` bot. Traced run 672 (schedule, main, red) line by line: main step fails → `exitcode '1': failure` → the `if: failure()` step runs → `POST /api/v1/repos/dohertj2/mxaccessgw/issues` with the built-in token masked to `***` → issue #139 created at the matching timestamp. Re-confirmed by a fresh forced-failure probe on the throwaway branch `test/tst25-check6-nightly-issue` (temporary `tst25-check6-probe.yml` reproducing the job shape with `exit 1` for the live step; run 677 → issue #140). Branch deleted, issues #125 and #140 closed with explanatory comments. **One real defect found and fixed** (`fix/tst25-nightly-issue-path`, not merged): `${{ github.server_url }}` is the runner-internal `http://gitea:3000`, so every filed issue's run link was unreachable from a browser. The API call must keep using it (the job container resolves `gitea` only on the docker network and has no LAN egress to the public origin), so the fix adds a `PUBLIC_SERVER_URL: https://gitea.dohertylan.com` job env used **only** for the browser-facing link in the issue body; the probe validated the fixed template (#140 carries a `https://gitea.dohertylan.com/...` link that returns 200). **Separately observed, not fixed:** the nightly has been red continuously since at least 2026-07-17 (run 672: `x86 Worker.Tests failed with exit code 1`, 1 failed / 398 passed / 11 skipped — the known `EventBurst_DrainLoopCoalescesFlushes` class of flake), and the step de-duplicates nothing, so 14 issues are open, seven of them (#132–#138) for the identical SHA `47c0b64`. Worth a follow-up: fix the red nightly, and consider having the step reuse an open issue with the same title instead of filing a new one. |
 | 2026-08-10 | **TST-24 → `Done`: per-client wire tests land for the two clients that lacked them** (branch `feat/tst-24-client-wire-tests`). Audit first corrected the finding's premise: **Go, Rust, and Java already had real-server wire tests** — `newBufconnClient`/`fakeGatewayServer` over `grpc/test/bufconn`, `spawn_fake_gateway` over a loopback `TcpListener` with tonic's `Server`, and `InProcessGateway`/`TestGatewayService` over `InProcessServerBuilder` — each already asserting the round trip, the server-observed `authorization` bearer header, and the `ReplayGap` sentinel. The real gaps were **.NET** (every test substituted `FakeGatewayTransport` for `IMxGatewayClientTransport`, and the test project had no server package) and **Python** (stub monkeypatching everywhere except one opt-in TLS test serving only `OpenSession`). Added `WireFakeGatewayServer` + `MxGatewayClientWireTests` (Kestrel h2c on `127.0.0.1:0` serving `MxAccessGatewayBase`; new `Grpc.AspNetCore.Server` 2.76.0 + `Microsoft.AspNetCore.App` refs on the test project) and `clients/python/tests/test_wire_fake_gateway.py` (`grpc.aio` server on `127.0.0.1:0`, no new deps). Four shapes each: full round trip with every reply field asserted, the bearer header **as received by the server** on the streaming RPC too, the `ReplayGap` sentinel surfaced as the client's typed signal, and a genuine `PERMISSION_DENIED` mapping to the typed authorization error. CI: the `portable` job only *built* the .NET client, so a `dotnet test` step was added. **The new tests immediately caught a shipped bug** — Python `GatewayClient.connect()`/`GalaxyRepositoryClient.connect()` constructed the `grpc.aio` channel inside `asyncio.to_thread`, which raises `RuntimeError: There is no current event loop in thread 'asyncio_0'` because a `grpc.aio` channel binds to the loop current on the constructing thread; every non-stub connection failed, and the one test guarding the off-loop behaviour (Client.Python-028) monkeypatched `create_channel` and so asserted the bug. Fixed by splitting `resolve_channel_security` (blocking TOFU probe, off-loop) from `create_channel` (on-loop), with the `-028` tests retargeted to assert both halves. Verified: .NET 133 passed/1 skipped (pre-existing live-gateway skip), Python 168 passed/1 skipped plus 6/6 opt-in TLS.
