Closes #1899 — AI-4364

What & why

A session with no work item shows a "This session" requester row in the work-context pane, and it drew a letter for any WorkOS user: the row could only build a picture from a github: id. The pane now asks /api/users/me/identity once per credential and uses the returned avatar_url when the requester is one of the viewer's ids, or when the launch names no requester (the daemon is the viewer's own). Anyone else keeps the github: fallback.

Needs kurrent-io/kcap-server#2644 to return the picture; against an older server the row keeps its letter, so the two can merge in either order.

Where to look

ServerWorkContextSource settles the viewer on any answer, a 404 included, and asks again only after a transport failure, a sign-out or an auth invalidation, so a server without the endpoint costs one request per credential.

Verification

Reader, client, source and view-model tests cover: the viewer read only when asked, a transport failure retried while a 404 settles, the identity asked once per credential and again after invalidation, and the requester row picking the viewer's picture for an own id, a merged github: id and no requester, but not for another user. dotnet publish -c Release shows no IL warnings.

Summary by CodeRabbit

  • New Features

    • Requester avatars now use the signed-in viewer’s avatar when the requester matches the viewer, including linked identities.
    • Viewer details are reused for up to five minutes and refreshed after that period or when authentication changes.
  • Bug Fixes

    • Requester avatars fall back to the existing GitHub avatar when the requester isn’t the signed-in viewer.
    • Stale viewer avatars are cleared when you’re signed out, and unavailable viewer details don’t prevent work context from loading.

A WorkOS id names no avatar, so the row read the session's requester and
showed a letter whenever the session had no work item.

Walkthrough

The work-context read path now retrieves viewer identity and caches it for up to five minutes within the current authentication generation. The view model uses the viewer’s avatar for an absent or viewer-owned requester and clears cached viewer state on terminal results.

Changes: Viewer identity flow

Layer / File(s) Summary
Viewer identity read contract
src/Capacitor.Cli.Core/WorkItems/ViewerIdentityDto.cs, src/Capacitor.Cli.Core/WorkItems/IWorkContextChannel.cs, src/Capacitor.Cli.Core/Models.cs, src/Capacitor.Cli.Core/WorkItems/WorkContextClient.cs, src/Capacitor.Cli.Core/WorkItems/WorkContextReader.cs, test/Capacitor.Cli.Core.Tests.Unit/WorkItems/*
The client requests /api/users/me/identity. The reader can request viewer identity alongside the summary read and reports the viewer body or a failure status. Tests cover identity parsing, ownership checks, optional viewer reads, and viewer response statuses.
Session identity caching
src/Capacitor.App/Services/ServerWorkContextSource.cs, test/Capacitor.App.Tests.Unit/ServerWorkContextSourceTests.cs
The source settles viewer identity for the current generation and reuses it on later reads for up to five minutes. A read that completes after the generation changes returns no viewer. Tests cover authentication invalidation, cache expiry, and generation changes during a read.
Requester avatar selection
src/Capacitor.App/ViewModels/WorkContextViewModel.Projections.cs, src/Capacitor.App/ViewModels/WorkContextViewModel.cs, test/Capacitor.App.Tests.Unit/WorkContextViewModelTests.cs
The view model uses the viewer avatar when the requester is absent or owned by the viewer. Otherwise, it resolves the avatar from the requester ID. Terminal results clear viewer state. Tests cover matching, absent, and nonmatching requesters, and signed-out reads.

Merge Risk: Low · up to a374f

The requester row can miss the viewer’s picture for an empty requester, and a slow identity lookup can delay the pane. These are localized issues that can be fixed or accepted before merging.

Security architecture risk: Low · up to a374f

The change enriches a displayed profile picture without granting additional access. A successful background account switch can leave the previous account’s identity attached to subsequent reads until refresh. Normal sign-in and rejected-credential paths invalidate the cache, limiting the concern.

Retained concerns

  • Low · security · inferred: A settled viewer is bound to the app’s invalidation generation, not the effective credential used by the HTTP handler. If another account replaces the same profile’s stored token and recovery successfully adopts it after a 401, the generation does not change. Subsequent successful reads can retain the former viewer identity within the five-minute reuse window, and a session with no requester can display that viewer’s picture. Explicit sign-in invalidation and final 401 handling protect other paths; no additional server authorization is gained.
Security review details

Security Blast Radius

  • inferred — The identified exposure is previous-viewer identity and avatar data retained within one desktop source across its sessions. The inspected consumer uses that identity for image selection, not authorization. Credential recovery remains profile- and server-bound, so this concern does not establish arbitrary tenant access or credential disclosure.

Security Findings and Attack Paths

  • inferred — The cross-account path requires an existing settled viewer, replacement credentials for the same profile and server, rejection of the active bearer, and successful recovery without app notification. The new cache can then attach the former viewer to reads under the replacement account. This is a conditional presentation-data isolation issue, not a demonstrated remote account takeover.

Trust Boundaries and Controls

  • observed — A final viewer 401 joins the existing any-401 signed-out rule. Sign-in notification explicitly invalidates authentication, and generation fencing prevents pre-invalidation identity from settling afterward. Avatar requests remain separate from bearer-authenticated server requests.

Resilience and Maintainability Implications

  • observed — Viewer transport and parsing failures degrade enrichment instead of settling an unusable identity. Caller cancellation propagates. These controls preserve retry and teardown behavior, but they do not detect a successful effective-account change inside recovery.

Hardening Proposals

  • proposed — Bind settled viewer identity to an effective-credential or principal epoch that also advances during successful recovery. This would close the unobserved account-switch path rather than relying on freshness expiry.

Explanation

Issue #1899 requires the "This session" requester row to show the viewer's picture when the requester is the viewer. The issue names GET /api/users/me/identity and its avatar_url as the source. The client side is implemented: WorkContextClient.GetViewerIdentityAsync requests the route. ViewerIdentityDto carries UserId, AvatarUrl, and Ids, and Owns matches the viewer's IDs, including a bare numeric ID treated as github:&lt;id&gt;. WorkContextReader reads the viewer when asked. ServerWorkContextSource settles the viewer per credential. In WorkContextViewModel.Projections.cs, ResolveRequesterAvatar uses _viewer.AvatarUrl when the requester is absent or owned by the viewer. Any other requester keeps the github: fallback, and a WorkOS-only non-viewer requester gets no picture. ApplyReady and ForgetViewer keep the avatar current. Tests cover route parsing, ownership, reader outcomes, source reuse and invalidation, and requester avatar selection. The picture only appears when the server returns avatar_url. That depends on kurrent-io/kcap-server#2644, which is outside this repository. The client-side requirements are met.

Full details: Out of Scope Changes check

Explanation

The changes support the viewer avatar feature or its correctness. The channel method, client route, reader overload, identity DTO, JSON registration, and view-model avatar selection implement the requested behavior. The source cache, five-minute lifetime, generation scoping, and optional TimeProvider keep the viewer identity fresh and limit requests to one per credential, as the PR description states. The reader change that maps a viewer-only 401 to SignedOut supports auth invalidation. ApplyTerminal calling ForgetViewer prevents a stale viewer avatar after a terminal state. The tests cover these paths. No unrelated behavior was found in the reviewed changes.

High-Level Assessment

Keep identity retrieval in the existing work-context read path: it reuses authenticated HTTP handling and gives the source control over per-credential caching and retries. A separate application-wide identity service would add lifecycle wiring for a single requester-row consumer.

Action required

1. A new account can show the old avatar ✓ Resolved
Description
ApplyReady replaces _viewer only when the read supplies a non-null identity; terminal reads also
leave the previous value in the view-model. After a sign-out and another sign-in, a ready read with
no viewer can resolve a requesterless session against the previous account’s avatar.

Remediation recommended

3. Identity sign-outs remain cached ✓ Resolved
Description
WorkContextReader.ReadAsync omits the viewer request’s HTTP status from its final-401 check and
sets ViewerFailed only for status zero. When the authorized identity route returns 401 while the
concurrent work-context requests succeed, ServerWorkContextSource receives Ready, settles a null
viewer, and neither retires the authenticated client nor requests identity again until
authentication is explicitly invalidated.
Code

src/Capacitor.Cli.Core/WorkItems/WorkContextReader.cs[R77-78]

+            Viewer       = viewer is { Succeeded: true } ? viewer.Body : null,
+            ViewerFailed = viewer is { StatusCode: 0 },
Relevance

●●● Strong

Omitting an identity request’s 401 from sign-out classification is a direct authentication-state
correctness bug.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The identity route requires authorization, and the viewer outcome retains its HTTP status, but the
reader excludes that status from the final-401 check. The source’s sign-out path runs only when the
reader returns SignedOut, so a nonzero viewer status instead produces a settled ready read with a
null viewer.

4. A malformed identity response blocks retry ✓ Resolved
Description
ViewerFailed treats only status zero as an unanswered request, even when a successful HTTP
response could not be parsed into a viewer body. A bodyless or malformed 2xx identity response
therefore makes ServerWorkContextSource settle a null viewer and skip later identity requests for
that credential.
Code

8. Concurrent panes repeat identity requests 🐞 Bug ➹ Performance
Description
ReadAsync snapshots _viewerSettled separately for each call before any viewer request finishes.
If sessions read concurrently while the viewer is unsettled, each starts its own identity HTTP
request, including repeated 404s against a server without the endpoint.

Recent accepted concurrency precedents favor preventing duplicate asynchronous requests from
independently captured stale state.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The settled flag changes only after the full awaited read, whereas every concurrent reader
independently starts the HTTP identity call when its captured flag is false.

P1 Badge Reject viewer results from retired credentials

When InvalidateAuthentication() runs while a work-context read is in flight, AuthenticatedServerReads allows the retired lease's borrower to finish, but this block publishes its viewer without checking the authentication generation. If a new-credential read finishes first and the old read finishes afterward, the old identity overwrites _viewer and leaves _viewerSettled true, so subsequent sessions can indefinitely display the previous account's avatar without querying the current identity; guard this update with the credential generation or otherwise serialize the identity read.

P2 Badge Include the viewer request in 401 classification

When the identity request is the only concurrent request to receive a final 401—for example, when the credential expires between responses—the preceding signed-out check ignores viewer, and this expression marks the result as settled rather than failed. ServerWorkContextSource therefore returns Ready, retains the authenticated client, and permanently caches an empty viewer for that credential instead of following the documented behavior that any final 401 signs the read out; include viewer.StatusCode in the 401 classification.

Treat an empty requester ID as absent.

When AgentStatusDto.Requester is "", UpdateRequester displays “You,” but _requesterId is null is false. Owns("") is also false, so a Ready read with a viewer avatar still shows the letter. Use the same blank-ID rule for display and avatar selection.

@codex review

The recovery handler can adopt another account's stored token without the
app seeing a credential change, so a settled viewer cannot live forever.

Minor · Bound the viewer identity lookup with its own deadline. · WorkContextReader.cs:42

src/Capacitor.Cli.Core/WorkItems/WorkContextReader.cs:42
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Bound the viewer identity lookup with its own deadline.

The viewer lookup is awaited after the assignments, summary, item, and topology reads complete. A slow /api/users/me/identity response therefore holds the work-context read open, even when the other reads have finished. The request has no deadline shorter than the HTTP client default of 100 seconds, so the pane can stay pending for that long. Give the viewer lookup a shorter, separate deadline. A timeout then returns a failed viewer outcome, which already sets ViewerFailed. Caller cancellation and the existing 401 check still apply.

🐛 Suggested fix
     public const string PlanGateError = "work_items_not_in_plan";
+    static readonly TimeSpan ViewerTimeout = TimeSpan.FromSeconds(5);
-        var viewerTask  = readViewer ? channel.GetViewerIdentityAsync(ct) : null;
+        var viewerTask  = readViewer ? ViewerWithinDeadlineAsync(channel, ct) : null;
+    /// The viewer lookup is optional, so it runs under its own deadline. A timeout becomes a failed
+    /// viewer outcome. The caller's cancellation still propagates.
+    static async Task<WorkContextOutcome<ViewerIdentityDto>> ViewerWithinDeadlineAsync(IWorkContextChannel channel, CancellationToken ct) {
+        using var deadline = CancellationTokenSource.CreateLinkedTokenSource(ct);
+        deadline.CancelAfter(ViewerTimeout);
+        try {
