Subject: [PATCH 01/10] fix: show profile images in user pickers

Reviewer and assignee editors were falling back to initials even though the surrounding detail view already knows the provider host used for synced profile images. Reusing that host keeps the picker aligned with repo summary avatars while preserving initials for manual or unknown users.

Validation: cd frontend && node ../node_modules/vite-plus/bin/vp test run --project unit src/lib/components/detail/UserPicker.test.ts src/lib/components/detail/UserListEditor.test.ts; node node_modules/vite-plus/bin/vp run frontend-package-check; node node_modules/vite-plus/bin/vp fmt --check frontend packages/ui '!frontend/dist/**' '!packages/ui/src/api/generated/**' '!frontend/test-results/**' '!packages/ui/test-results/**' --no-error-on-unmatched-pattern --threads=1

Subject: [PATCH 02/10] fix: fall back when picker avatars fail

Profile images in the user picker can still fail at browser load time for accounts that do not expose a provider image or whose generated URL is not fetchable. Leaving the broken image in place made bot and service accounts harder to scan than the original initials fallback.

Track failed avatar loads per username and return those rows to the existing initials presentation. Loaded user photos remain unchanged, and manual or unknown users still use initials immediately.

Validation: cd frontend && node ../node_modules/vite-plus/bin/vp test run --project unit src/lib/components/detail/UserPicker.test.ts src/lib/components/detail/UserListEditor.test.ts; node node_modules/vite-plus/bin/vp run frontend-package-check; node node_modules/vite-plus/bin/vp run frontend-check; cd frontend && ../node_modules/.bin/svelte-check --tsconfig ./tsconfig.json --fail-on-warnings; node node_modules/vite-plus/bin/vp fmt --check frontend packages/ui '!frontend/dist/**' '!packages/ui/src/api/generated/**' '!frontend/test-results/**' '!packages/ui/test-results/**' --no-error-on-unmatched-pattern --threads=1; git diff --check. Live dev-ephemeral picker inspection showed failed roborev/renovate/github-advanced-security avatar URLs rendering initials while valid user images remained images. Note: svelte-mcp autofixer exited 1 with no output twice, so svelte-check via frontend-package-check was used for Svelte validation.

Subject: [PATCH 03/10] fix: gate picker avatars by provider

User pickers were synthesizing GitHub-style avatar URLs from host and login for every provider. That breaks provider-collision and non-GitHub routes because a GitLab, Gitea, or Forgejo username is not guaranteed to resolve through https://{host}/{login}.png.

Until the API carries real provider avatar URLs, keep synthesized image URLs on GitHub routes only and let other providers use the existing initials fallback instead of issuing known-wrong image requests.

Validation: red/green Playwright coverage for the Gitea provider-collision picker fallback.

Subject: [PATCH 04/10] test: stabilize GitLab retry fixtures

GitLab client-go retries 429 and 5xx responses by default, which made httptest fixtures spend seconds in retry backoff and left CI-sensitive transient-error assertions dependent on the upstream retry loop.

Keep production retries unchanged, but let GitLab tests opt out through the local test helper so fake upstream responses are observed exactly once and error propagation tests stay deterministic.

Validation: go test ./internal/platform/gitlab -shuffle=on; patched PR merge checkout: go test ./internal/platform/gitlab -run TestClientListOpenMergeRequestsPropagatesTransientForkHeadRepoLookupFailures -shuffle=1781917566125672115; patched PR merge checkout: go test ./internal/platform/gitlab -shuffle=1781917566125672115. Full local gotestsum was attempted against the PR merge checkout; GitLab passed, but current main has separate macOS PTY/tmux local failures not present in the failing CI job.

Subject: [PATCH 06/10] test: stabilize picker avatar e2e assertions

Avatar picker coverage needs to prove the detail flows render provider image URLs without depending on GitHub being reachable from CI or developer machines. Stubbing those image requests keeps the test focused on UI wiring and avoids racing the component fallback that removes failed images.

Subject: [PATCH 07/10] fix: scope comment autocomplete by provider

Comment autocomplete routes were resolving provider-qualified repositories and then dropping the provider before looking up users and references. That let same-host/same-path repositories leak candidates across providers, which made the Gitea collision picker pass by showing a GitHub-owned user.

Thread the resolved provider into the DB lookup so suggestions are scoped by the full repository identity. The e2e assertion now expects the Gitea fixture author and verifies the GitHub candidate is absent.

Validation: go test ./internal/db -run 'TestListCommentAutocomplete|TestGitLabRepoPathCaseHandling' -shuffle=on; go test ./internal/server -run 'TestAPICommentAutocomplete' -shuffle=on; cd frontend && ../node_modules/.bin/vp exec -- playwright test --config=playwright-e2e.config.ts tests/e2e-full/assignees-reviewers.spec.ts --project=chromium --grep "non-GitHub issue picker"; cd frontend && ../node_modules/.bin/vp test run --project unit; cd frontend && ../node_modules/.bin/vp exec -- playwright test --config=playwright-e2e.config.ts tests/e2e-full/assignees-reviewers.spec.ts

Subject: [PATCH 08/10] test: stabilize runtime exit-frame coverage

Full local server validation exposed that the runtime exit-frame e2e was asserting a PTY EOF timing window that the available backends do not reliably create. Real tmux and ptyowner attachments can deliver the frame at process exit, so the test failed while the user-visible contract still held.

Keep the real runtime e2e focused on receiving the exited frame, and pin the outputDone-before-Done bridge race with controlled attachment channels where that ordering can be represented directly.

Validation: go test ./internal/server -run 'TestWorkspaceRuntimePlainShellTerminalDeliversExitFrameE2E|TestBridgeRuntimeAttachmentOutputClosedEmitsExitFrameBeforeDone' -shuffle=on; go test ./internal/db ./internal/server -shuffle=on

Subject: [PATCH 09/10] test: cover provider-scoped reference autocomplete

Roborev flagged that the provider-collision fix covered user autocomplete through the picker but only covered reference autocomplete at the DB boundary. The route-level reference path also needs full-stack coverage so a future handler regression cannot drop provider identity while DB tests still pass.

This adds an API+SQLite collision test for trigger # that proves a Gitea route on github.com/acme/widget returns the Gitea issue reference instead of the GitHub issue with the same host and path.

Validation: red check with the reference handler temporarily forced to github failed by returning issue #1 instead of #901; go test ./internal/server -run TestAPICommentAutocomplete -shuffle=on; go test ./internal/server -shuffle=on

Subject: [PATCH 10/10] test: cover GitLab reference autocomplete collisions

The provider-scoped reference coverage now includes the GitLab-only ! trigger, which follows the same route and DB lookup as # but filters merge requests. Without this, a handler regression could still leak merge request suggestions from a same-host non-GitLab repo while the # path stayed covered.

The regression was verified red by temporarily forcing the reference handler to use the Gitea provider, which returned pull #1 instead of the routed GitLab MR #901.

Validation: go test ./internal/server -run TestAPICommentAutocompleteGitLabMergeRequestReferencesScopesByProvider -shuffle=on failed with the temporary provider break; go test ./internal/server -run 'TestAPICommentAutocomplete' -shuffle=on; go test ./internal/server -shuffle=on
