feat(studio): port 3.9 permission gating onto IdentityPermissionContext - #8586
Merged
Merged
Conversation
Environments and JWT refresh raise a no-dep IPermissionRefreshSignal instead of taking IPermissionSnapshotCache, so Security plus Environments can resolve. Invalidate bumps a generation token, drops the snapshot, then raises Changed so PermissionView and NavMenu re-fetch after sign-in, environment switch, and silent refresh. Sign-out stays on the page when token clear fails. Co-authored-by: Sipke Schoorstra <sipkeschoorstra@outlook.com>
Adding the Environments project reference made Microsoft.Extensions and Elsa.Studio.Security extension types collide. Co-authored-by: Sipke Schoorstra <sipkeschoorstra@outlook.com>

Elsa 3 Code Review: REQUEST_CHANGES + HIGH @ 1572857
Code Review, Round 3/4
Scope: core#8586 @ 1572857d, base main 8d88d04f (includes #8572), merged in via b302ee38. Since Round 2 (7b1c75ca): 28 files, +1412/−119. PR B of the F4 Studio forward-port.
Design reviewed against: the release lead's ruling. Port onto main's fail-closed IdentityPermissionContext (GET /identity/me/permissions).
Summary
Good progress. Both Round 2 blockers are fixed in substance:
- The Security + Environments hang is gone. I re-ran my Round 2 repro with the modules' real registrations; it resolves at once in two scopes.
- What re-renders no longer depends on DI construction order. I re-ran the zero-grant-after-admin repro with a
PermissionViewconstructing the cache first; the admin action disappears.
The fidelity gaps are closed, CI is green with all 17 Studio test projects, and #8585 and #8572 survived the merge intact.
This is Round 3 of 4, so every remaining blocker below is listed with the exact change and the test that should prove it. There are five, and all are small:
- The refresh signal is a process-wide singleton, so on Blazor Server one user's token refresh or environment switch invalidates every user's cache (3.1). One line fixes it.
- The generation token has three race and stale-return holes (3.2).
- The Users and Roles access boundaries never re-resolve (3.3).
- The NavMenu hook is untested (3.4).
- The "real expired-JWT" test doesn't use its JWT (3.5).
Gate: Greptile 4/5, and 14 threads are open (section 6).
1. Claim-by-claim verification
| # | Claim | Verdict | Evidence |
|---|---|---|---|
| 1 | DI cycle broken by IPermissionRefreshSignal; IdentityPermissionContext is the only cache owner |
True |
|
| 2 | Generation token; Changed after clear; components follow Changed; stale load not stored; hook tests fail when their hook is removed |
Mostly true |
|
| 3 | Fidelity: the 18 tests, the AUTHENTICATION_ARCHITECTURE hunk and the #1103 items; two exclusions | True | Section 2 |
| 4a | SignOut_WhenClearingTokensFails_DoesNotNavigateToLogin |
True | It fails if the early return is removed. One should-fix in section 4. |
| 4b | A real expired-JWT permission test | False | 3.5 |
| 4c | Release notes and authorization-model.md |
Mostly true | POST-only logout, the cache contract and both constructors are documented. Gaps are listed in section 4. |
| 4d | CustomElements Unknown-mode doc | True | authorization-model.md and the PR body both say the CustomElements host runs without Security. |
| 4e | Body updated for #1089/#1096/#1097 on PR C | True | Three rows in the excluded table. |
| 5 | All 28 threads resolved, each with a reply | Resolved: true. Each with a reply: false. | Six code-quality threads were resolved with no reply: 4173656647 and 4173656650 (constant condition, Index.razor.cs), and 4173656652, 4173656660, 4173656662 and 4173656665 (generic catch). 14 new threads are open (section 6). |
| — | Merge kept #8585 and A | True |
|
2. Fidelity (re-run)
I compared every added line of each source hunk against the head file.
| Item | Result |
|---|---|
#1075 RoleEditorSurfaceTests: the 12 advanced-grant tests |
Ported. 155 of 156 added lines are present. The remaining one, Assert.DoesNotContain("Direct grant", …), guards a label that core never had; core asserts the grant's aria-label instead. That adaptation is fine. |
#1075 LoginChooserTests: the 4 busy-state tests |
Ported. The only difference is Change(...) → Input(...) on the two fields, which is equivalent. |
#1075 External Authentication HasAsync_HonorsCoreGrantsAndWildcards / HasAsync_RejectsGrantsThatDoNotCoverTheRequirement |
Ported onto IPermissionService, with identical InlineData. Dropping HasAsync_FailsClosedWithoutPermissionClaims is justified, because it is claims-specific; HasAsync_WhenPermissionServiceIsMissing_FailsClosed covers the same intent. |
#1075 AUTHENTICATION_ARCHITECTURE.md |
Both added lines were already present. My Round 2 finding was wrong, and the Engineer's "already identical" is correct. |
#1103 Index.razor.css, blueprint, 007 PRD |
All added lines present. |
#1103 FeatureCatalogTests |
#1103 added one test, InitializeFeatures_IsReportedThroughTheEnvironmentAwareService, and it is ported. The file didn't exist on main, so its companion tests came along, adapted to FullName. The source comment above the test was dropped (nit). |
Exclusion: ClaimsPermissionService |
Holds. The ruling requires /identity/me/permissions. |
| Exclusion: FeatureCatalog short-name matching | Holds. Main's DefaultFeatureService matches RemoteFeatureAttribute.Name against FullName (line 46). Short-name matching would be a behaviour change outside this port. |
3. Blocking findings (all required for Round 4)
3.1 The refresh signal must be scoped, not a process-wide singleton
AddCoreInternal registers TryAddSingleton<IPermissionRefreshSignal, PermissionRefreshSignal>(). On Blazor Server every circuit's IdentityPermissionContext subscribes to that one instance.
Probe (real module registrations, two scopes from one provider, environment switch in scope A):
| Signal lifetime | Changed in scope A |
Changed in scope B (another user) |
|---|---|---|
| Singleton (this head) | 1 | 1 |
| Scoped | 1 | 0 |
Effect:
- Every user's silent JWT refresh, and every environment switch, invalidates every connected circuit. Each one re-fetches
/identity/me/permissionsand re-renders its guards, views and menu. That is O(users) backend calls per refresh, across all users. Invalidate()also runs on other circuits' threads, which is what makes the races in 3.2 reachable.- CodeRabbit (Major) and Greptile (P2) flag the same thing.
Scoped works because:
DefaultEnvironmentServiceandJwtTokenProviderare scoped.- The authenticating handler resolves
ITokenProviderfrom the circuit's scope throughIBlazorServiceAccessor. - The signal still has no dependencies, so the cycle stays broken.
Required:
- Change the registration to
services.TryAddScoped<IPermissionRefreshSignal, PermissionRefreshSignal>();. With only that change, Security (138) and Environments (19) tests all pass. - Add a test: two scopes from one provider with
AddEnvironmentsModule+AddSecurityModule;SetCurrentEnvironmentin scope A raisesChangedin A and not in B. - Update the remarks on
IPermissionRefreshSignal("process-wide"), the comment inAddCoreInternal,authorization-model.md("a no-dependency singleton") and the PR body.
3.2 Make the cache's read and store atomic, and never hand out superseded grants
IdentityPermissionContext has three holes. Each matters once Invalidate() can run on another thread. After 3.1 that can still happen, because JwtTokenProvider raises from the HTTP handler pipeline, whose continuations can run on the thread pool.
- (a) The fast path reads the field twice.
if (HasCachedSnapshot) return _snapshot!;reads_snapshottwice. AnInvalidate()between the two reads returnsnullthrough the!.- Fix:
var snapshot = _snapshot; if (snapshot is { State: not IdentityPermissionSnapshotState.Unavailable }) return snapshot;. Do the same for the check inside the lock.
- Fix:
- (b) Check-then-store is not atomic with
Invalidate(). AnInvalidate()landing betweenif (generation != Volatile.Read(ref _generation))and_snapshot = loadedstores the superseded grants afterChangedhas already fired. Nothing re-resolves after that, so the UI keeps them until the next invalidation.- Fix: a small
_synclock around both sides:lock (_sync) { if (generation == _generation && loaded.State != Unavailable) _snapshot = loaded; }andlock (_sync) { _generation++; _snapshot = null; }, raisingChangedoutside the lock. Or publish(generation, snapshot)as one immutable object withInterlocked.CompareExchange.
- Fix: a small
- (c) An overtaken load returns the superseded grants to its caller. That is
return HasCachedSnapshot ? _snapshot! : loaded;, andGetAsync_WhenInvalidatedDuringLoad_DoesNotCacheTheStaleSnapshotcurrently asserts it (stale.HasPermission(users:view)is true). Any caller that doesn't re-resolve onChangedkeeps them. 3.3 shows a concrete one. CodeRabbit raised this as a security finding (CWE-863).- Fix: when the generation moved, loop and load again (or return the newer cached snapshot), so
GetAsynconly ever returns grants for the current generation. - Change the test to assert that the overtaken caller receives the new, zero-grant snapshot. Add a test that calls
Invalidate()between the generation check and the store, using a hook or a paused fake.
- Fix: when the generation moved, loop and load again (or return the newer cached snapshot), so
3.3 The Users and Roles access boundaries don't re-resolve
UserAdministrationAccessBoundary and RoleAdministrationAccessBoundary load their access once in OnInitializedAsync, and again only from their own "Try again" button. Neither subscribes to IPermissionSnapshotCache.Changed.
Probe (bUnit, the same registrations as AddSecurityModule): users view,create,update,delete → view only, then an auth change. The boundary still renders CanCreate = True and made no second request. The page guard above it stays, because view is still granted, so the create, edit and delete actions stay visible. The backend still refuses them. Round 2 required that permission-dependent UI re-resolves after invalidation.
Required:
- In both boundaries, subscribe to every
IPermissionSnapshotCache.Changed(resolved as the tracking base does), and callInvokeAsync(() => LoadAccessAsync(_lifetime.Token)). Unsubscribe inDisposeAsync. - Add one test per boundary: full grants → view-only + auth change hides create/update/delete; and an environment-style
Invalidate()does the same.
3.4 The NavMenu Changed hook has no test
Reverting NavMenu to auth-only (if (_caches.Length > 0) → if (false)) passes all 119 Core tests. So an environment switch or silent refresh that leaves the menu showing the previous grants would go unnoticed. The claim that "each fails when its hook is removed" doesn't hold for NavMenu.
Required: a NavMenu test with a cache present. Render the menu with an item that requires a grant, remove the grant, call Invalidate() (or raise the signal), and assert the item disappears. It must fail under the revert above.
3.5 The "real expired-JWT" test doesn't use the JWT
PermissionService_WhenTokenIsExpired_FailsClosed now creates an expired JWT and asserts IsExpired(). The token is never passed to anything: the IMePermissionsApi stub still returns 401 unconditionally, exactly as the anonymous test does. Round 2 asked for this test to be renamed or made real.
Required: one of these.
- Make it real: drive an expired access token through
ElsaIdentityAuthenticatingApiHttpMessageHandler→JwtTokenProvider, with a failing refresh, so the 401 leads to a known empty set. Optionally add a second case where the refresh succeeds and grants load with the new token. - Or delete the unused JWT and rename the test to what it checks, e.g.
PermissionService_When401_FailsClosed.
4. Should-fix (not blocking)
- Sign-out failure is silent to the user. When clearing fails twice, the service logs an error and returns. The user clicked "Sign out" and sees nothing happen. Show a message through
IUserMessageService(for example, "Sign-out could not clear this browser's session. Try again.") and assert it inSignOut_WhenClearingTokensFails_DoesNotNavigateToLogin. - Release notes and
authorization-model.md:- Name the public
HostedAuthenticationPaths.LogoutFormAction. The notes say the form posts toNavigationManager.ToAbsoluteUri("authentication/logout"), which isn't what the code does. - List the
IdentityPermissionContextconstructor change. Main's two-argument constructor is gone, which breaks compiled callers. - Mention that
AddOpenIdConnectAuthnow registersAddControllersWithViews(). - Fix the "singleton" wording after 3.1.
- Name the public
- Explanatory comments dropped from
Index.razor.cs, both dashboardFeature.csfiles and theIFeatureService.IsInitializeddoc are still missing (open since Round 2), along with theFeatureCatalogTestscomment. - Constructor parameter:
IdentityPermissionContexttakesIEnumerable<AuthenticationStateProvider>, which constructs every registered provider just to subscribe. An optionalAuthenticationStateProvider? authenticationStateProvider = nullsays what is meant. (Nit.)
5. Tests and revert checks
CI on this head ran all 17 Studio test projects, and all passed: Security 138, Environments 19, External Authentication 465, Core 119, Dashboard 107, Administration 60, Workflows 479 and the rest. Locally in Release, Core, Security, Environments, Dashboard and Administration match. External Authentication showed timing-only failures on my overloaded machine; it passes 465/465 in CI.
| Mutation | Result |
|---|---|
H1: cache doesn't subscribe to AuthenticationStateChanged |
caught (PermissionView_AfterSignInChangesToZeroGrant_HidesTheAdminAction) |
| H2: cache doesn't subscribe to the refresh signal | caught (environment-switch and silent-refresh tests) |
H3: DefaultEnvironmentService doesn't raise |
caught (PermissionView_AfterEnvironmentSwitch_ReloadsGrants) |
H4: JwtTokenProvider doesn't raise |
caught (PermissionView_AfterSilentTokenRefresh_ReloadsGrants) |
| H5: overtaken load is stored | caught (GetAsync_WhenInvalidatedDuringLoad_DoesNotCacheTheStaleSnapshot) |
H6: Invalidate() doesn't raise Changed |
caught (4 tests) |
H7: tracking base follows auth only, ignoring Changed |
caught (2 tests) |
| H8: NavMenu follows auth only | not caught (3.4) |
| H10: sign-out navigates despite a failed clear | caught (SignOut_WhenClearingTokensFails_DoesNotNavigateToLogin) |
| Signal registered as scoped (the 3.1 fix) | all Security and Environments tests still pass |
6. Gate status @ 1572857
- CI: green.
ubuntu-latest(Compile + Test, including all 17 Studio projects and the smoke tests) succeeded at 19:26 CEST. CodeQL/Analyze,pack-studio-core,pack-slack-only,select-tests, solution filters, GitGuardian, CLA, CodeRabbit and the Greptile check all pass.run-affected-testsis skipped, as it is dispatch-only. - Greptile: 4/5 on
1572857d(reviewed 19:19 CEST; 5/5 needed). Two P2s:- cross-user refreshes (3.1);
- required class braces.
UngatedPage,DashboardPageandWorkflowInstancesPageinPermissionPageGuardTests.cs(lines 373, 376, 415) are declared: ComponentBase;without a body. Give them{ }.
- Review threads: 42 in total. The 28 earlier ones are resolved, six of them without a reply (section 1). 14 new threads are open, all posted 19:18–19:19 CEST:
- Greptile: cross-user refresh and braces;
- CodeRabbit: the singleton signal (Major), the superseded grants returned to callers (security), and a blueprint/PRD rule (load the overview when only
workflows/runtime:viewis held); - code quality: 9 threads (generic catches, the
Index.razor.csconstant conditions again, an undisposedHttpResponseMessagein the sign-out tests).
- Mergeability:
MERGEABLE, stateBLOCKED(reviews). - Greptile's outside-diff note, about
WorkflowDashboardContributorruntime-status isolation, is backend code from #8572 that is already on main. It isn't this PR's to fix; track it separately.
Maintainability (HIGH bar)
The signal and generation design is the right shape, and it is far easier to follow than Round 2's:
- one owner of the cache;
- producers that only raise a dependency-free signal;
- consumers that follow a single
Changedevent, with documented semantics onIPermissionSnapshotCache.
The XML docs say what happens and why. Three points remain:
- The lifetime is part of the contract. A per-user signal must be scoped, and the docs should say so (3.1).
- The concurrency rules belong in the code. Name the invariant on
IdentityPermissionContext: "a snapshot is stored only for the generation it was loaded under, andGetAsyncreturns only current-generation grants". Implement it with one lock or one atomic publish, so a reader doesn't have to reason about interleavings (3.2). - Every
Changedconsumer should be visible. The tracking base, NavMenu and the two access boundaries should share one small pattern, or a helper, so the next consumer doesn't miss it (3.3).
Required for Round 4
- Register
IPermissionRefreshSignalas scoped. Add the two-scope isolation test and update the docs and body (3.1). - In
IdentityPermissionContext: read_snapshotonce on the fast paths; make generation check-and-store and invalidate atomic; never return superseded grants. UpdateGetAsync_WhenInvalidatedDuringLoad_DoesNotCacheTheStaleSnapshotto expect the new grants, and add the between-check-and-store test (3.2). - Make the Users and Roles access boundaries reload on
Changed, with one test each (3.3). - Add a NavMenu test that fails when its
Changedhook is reverted (3.4). - Make the expired-JWT test real, or rename it and drop the unused JWT (3.5).
- Add braces to the three test page classes. Reply to and resolve the 14 open threads, and add replies to the six resolved without one. Get Greptile to 5/5 (section 6).

Elsa 3 Code Review: APPROVE + HIGH @ c67ff78
Code Review, Round 5/5 (final, extra round approved)
Scope: core#8586 @ c67ff78d, base main 8d88d04f. Since Round 4 (e07d2e3a) there are three commits:
a244d07e: B1, B2, the three threads, the corrected reply on 4174098626, and the nits;c937a27a: disables admin mutations while access is re-checked;c67ff78d: test-only fix for the queued-refresh race.
As agreed, I reviewed only B1, B2, those threads and the claimed nits, plus regressions against Round 3 and Round 4 behaviour.
Summary
Approve. Both Round 4 blockers are fixed in production code:
- B1: the reload loop is gone, real permission changes still reach the UI, and a failed refresh fails closed.
- B2: the editors stay mounted, the spinner shows only on first load, mid-check changes are coalesced, and mutations are disabled during a re-check and re-enabled after.
The only problem at c937a27a, the flaky queued-refresh test that made CI fail, is fixed by the test-only commit c67ff78d. That fix is stable locally. Every revert probe for the new behaviour fails a named test, and every Round 3 and Round 4 revert probe still does.
Gate met: CI is green on this exact head, Greptile is 5/5 on this exact head, all 49 threads are resolved with replies, and the PR is MERGEABLE/CLEAN.
The follow-ups at the end are all non-blocking.
1. Delta since c937a27a: test-only, confirmed
git diff c937a27a c67ff78d touches one file, SecurityMenuAndBoundaryTests.cs (+16/−6). It changes only the end of the two Render_WhenChangedArrivesDuringACheck_KeepsEditsAndHonoursTheQueuedRefresh tests:
- the final assertions now run inside one
WaitForAssertion:create:False, no "Checking access",Calls == 3and an emptyResultsqueue; - after that, the draft must still read
"kept".
There is no production change.
Why this is enough:
- At
c937a27athe final wait passed immediately, because the view-only copy shown during the re-check also readscreate:False.Calls == 3was then checked before the queued third call started. CI run 37146137227 failed on exactly that (Expected: 3, Actual: 2). - Now the wait cannot finish until the third call has run and taken the queued result.
- The markup still can't tell the in-check copy from the queued view-only result, since both show
create:False. Renderingupdatewith a distinguishable third result would close that gap. That's optional.
Stability at c67ff78d:
| Run | Result |
|---|---|
| The test alone (Role + User), 30 runs | 30/30 passed; at c937a27a, 0/25 |
| Full Security project, 10 runs | 10/10 passed (145/145 each); at c937a27a, about 1 failure in 7 |
Revert: a mid-check Changed is dropped (both boundaries) |
caught (both tests fail) |
2. B1: endless reload loop, fixed
- Signal only on real changes:
JwtTokenProviderraises the signal only when the refresh failed, or the old and new tokens differ insuborpermissions. The values are compared as sorted ordinal sequences, and a missing or unparsable refreshed token counts as changed. - The comparison covers what the UI depends on.
/identity/me/permissionsevaluates the bearer principal, andDefaultElsaTokenServicealways issuessubplus onepermissionsclaim per grant (nonewhen there are none).- Reordered values, or a single string versus a one-item array, don't signal.
- An added, removed or changed value signals, and so do a changed
subandnone→ grant. [a,a]→[a]also signals. That's harmless; the backend never issues duplicates.
- Probes:
- Round 4 livelock (the refreshed token keeps landing inside the 2-minute window, same claims): now 1 load, 0 signals. At
e07d2e3ait ran about 1.43 million loads in 5 s. - Changed claims: 1 signal, then it settles after 2 loads.
- Failed refresh: 1 signal, tokens cleared, then
Forbidden, which fails closed.
- Round 4 livelock (the refreshed token keeps landing inside the 2-minute window, same claims): now 1 load, 0 signals. At
- Cap: after the cap, an uncached
Unavailableis returned. The cap is 3 loads, i.e. 2 retries; the docs say "retried at most three times" (wording nit). Reaching the cap logs nothing. - Tests:
GetAsync_WhenNearExpiryRefreshKeepsSubAndPermissions_DoesNotLoopandGetAsync_WhenOvertakenReloadCapIsReached_ReturnsUnavailableWithoutCachingeach fail when their behaviour is reverted.PermissionView_AfterSilentTokenRefresh_ReloadsGrantsnow refreshes to a same-subtoken with a differentpermissionsclaim, which proves a real permission change still updates the UI.
3. B2: access boundaries, fixed
- No more remount: the boundaries no longer clear
_access. The spinner shows only on first load, and a mid-checkChangedsets_reloadRequested, which the loop then runs. - Mutations disabled during a re-check (
c937a27a):DisplayedAccesspasses a copy withCanCreate/CanUpdate/CanDeletefalse while a re-check of Ready access is running. The flag is cleared infinally, and the method renders once more at the end. - Probes (real context, access service and boundary):
| Case | Result |
|---|---|
Changed with unchanged grants |
no remount, no spinner |
| Admin → view-only | flips in place |
| Zero grants | content hidden |
| Re-check returns full access | disabled during the check, re-enabled after |
| Re-check throws, or returns Unavailable | Unavailable alert (fail closed); "Try again" recovers |
| Stuck re-check | disabled while pending, no remount. In production the backend HTTP timeout bounds the wait, then it becomes Unavailable, so it can't stay disabled forever. |
| Dispose | 0 Changed subscribers left |
- Drafts: they survive on the edit pages. The editors reload only when their Id changes.
4. Revert checks
| Mutation | Result |
|---|---|
Always or never raise on a successful refresh; compare sub only |
caught |
| Remove the overtaken-reload cap | caught (the test hangs; the blame-hang timeout aborts it) |
Boundary clears _access before a check; boundary drops a mid-check Changed (User / Role) |
caught |
| No downgrade during a re-check; no render at the start of a re-check; always downgrade | caught |
| Round 3/4 regressions: H1–H3, H5, H5b, H6, H7, H8 (NavMenu), H10 (sign-out), signal back to singleton, boundary subscriptions removed | all still caught |
| Failed refresh doesn't raise | not caught (test gap; the code is correct per the probe) |
5. Threads and nits
- All 49 threads are resolved, each with a reply. None are open.
- I re-read the replies posted on this round's threads:
- 4174464590 (CodeRabbit, the queued-refresh race): the reply cites CI run 37146137227 and the
c67ff78dfix. CodeRabbit confirmed the race is addressed and resolved the thread. Accurate. - 4174461472 and 4174461478 (code quality, "constant condition" on
!_disposed): answered as false positives, becauseDisposeAsynccan set_disposedwhileGetAsyncis awaited. That is correct; the analysis assumes a single thread.

- Earlier required threads:
- 4174270385, 4174262142 and 4174262154 are resolved with accurate replies;
- 4174098626 now gives the right reason (
Index.RequiredScopealready loads the overview for runtime-only users) and the doc sentences are fixed; - 4174421427 (old admin controls stay active) was fixed by
c937a27a.
- Nits:
AfterLoadis test-only ([EditorBrowsable(Never)], documented);TestWidgethas a body;- the blueprint and PRD runtime-view text is corrected;
- the release notes now name
HostedAuthenticationPaths.LogoutFormAction, fix theToAbsoluteUridescription and mentionAddControllersWithViews().
6. Gate status @ c67ff78
- CI: green on
c67ff78d.ubuntu-latest(Compile + Test) succeeded at 21:45 CEST in 22 min. All 17 Studio test projects passed with 0 failures: Security 145, Core 120, Environments 20, External Authentication 465, Workflows 479, Dashboard 107, Administration 60, Workflows Designer 83 and the rest. The smoke tests passed 9/9.- Both CodeQL Analyze (csharp) jobs pass, as does the aggregate
CodeQLcheck.pack-studio-core,pack-slack-only,select-tests, solution filters, GitGuardian, CLA, CodeRabbit and the Greptile check all pass. run-affected-testsis skipped, as it is dispatch-only.
- Greptile: 5/5 on
c67ff78d(last reviewed commit = this head, 21:29 CEST): "No outstanding findings block merging". The outside-diff summary says no findings remain. - Threads: 49 in total, 0 open, 0 resolved without a reply.

7. Greptile's 1/5 on #8587 (stale administration data after a user or environment switch)
- User switch: not reachable.
- Every sign-in and sign-out path navigates away, mostly with a forced reload. Login pages are separate routes, so the admin page is unmounted before a new user signs in.
- A silent refresh can't change
sub: the backend resolves the refresh bysub. - A failed refresh leads to
Forbidden→ Access Denied.
- Environment switch: real, but it predates this PR, and it isn't a disclosure.
- Nothing reloads pages on a switch; only
EnvironmentPickerre-renders. So the admin page keeps showing data from the previous backend, to the same user, who was allowed to see it there. - If the new environment also grants access, the controls re-enable, and a Save would send the old draft to the new backend.
- Base main does the same on every Studio page, without even re-checking access. This PR is strictly better: it re-checks against the new backend, disables mutations meanwhile, and shows Access Denied or Unavailable when refused.
- Nothing reloads pages on a switch; only
- Ruling: out of scope for B2 (preserving drafts on a permission re-check), not a blocker; follow-up below.
Non-blocking follow-ups
- Reload page data on environment switch, app-wide. For these two pages, keying
ChildContenton the backend URL the access was checked against would make a backend change remount the editor while same-backend re-checks keep drafts. - Create pages: during a re-check,
CanOpen => _isCreate ? Access.CanCreate : …renders "your current sign-in cannot create a role/user" and unmounts the form.- The committed values survive, but text in the field being typed in, not yet committed, is lost.
- Treat a re-check as read-only on create pages instead.
- Release notes: list the removed two-argument
IdentityPermissionContextconstructor, which is a binary break. - Add a test that a failed refresh raises the signal.
- Change the cap wording to "3 loads, 2 retries" and log a warning when the cap is reached.
- Optionally make the queued-refresh tests prove the third result is rendered (render
update, with a distinguishable third result). - From Round 3, still open:
- failed sign-out is silent to the user (
IUserMessageService); - restore the dropped explanatory comments;
- the
IEnumerable<AuthenticationStateProvider>parameter nit.
- failed sign-out is silent to the user (
Verdict
APPROVE + HIGH @ c67ff78d0a67a7b05116b549fb7b8dad1055573b. Every Round 3 and Round 4 blocker is fixed, nothing new is blocking, and the gate is met: CI green, Greptile 5/5 and no open threads, all on this head.
PR C must re-merge exactly this head, c67ff78d0a67a7b05116b549fb7b8dad1055573b, and nothing later. The Engineer reports that C was already re-merged onto it as cf32c527f; verify that against C's history before C's own review. If B moves again, this approval doesn't carry over.

Purpose
Port elsa-studio

Closes elsa-workflows/elsa-studio#1111
Those two issues live in elsa-studio, not this repository. GitHub will not auto-close them from an elsa-core PR; they should be closed manually after this merges.
This is PR B of the F4 split. PR A (#8572) has merged into main (
8d88d04f). This branch merged that commit so CI runs against A's logout, RevokedSessions, and dashboard backends.Do not start leftover Studio UX ports here (#1077, #1090, #1094, #1098). That is PR C (#8587).
