• 🔴 (10:25) User stated apiRequestToRegion always sends JSON and explicitly sets Content-Type; SDK functions set their own Content-Type; rawApiRequest may intentionally omit Content-Type, including for string bodies.
• 🟡 (10:25) packages/cli/src/lib/sentry-client.ts was modified.
• 🟡 (10:26) packages/cli/src/lib/sentry-client.ts redirect-security implementation adds MAX_REDIRECTS = 20, documented as matching native fetch.
• 🔴 (10:26) User directive: Never forward headers across an unvalidated origin; redirect destinations must be validated before rebuilding/forwarding bearer credentials and custom headers.
• 🟡 (10:26) Redirect handling in packages/cli/src/lib/sentry-client.ts was changed to use manual redirects. Added FetchWithTimeoutArgs.token: string, FetchWithTimeoutResult containing { response: Response; headers: Headers }, isRedirect() for statuses 301, 302, 303, 307, and 308, getRedirectUrl(), and getRedirectRequest().
• 🟡 (10:26) getRedirectUrl(response, request) throws ApiError when a redirect has no Location header, with message Redirect (${response.status}) had no Location header, HTTP status, and request.url; it resolves redirect locations relative to request.url.
• 🟡 (10:26) Redirect request behavior in packages/cli/src/lib/sentry-client.ts converts applicable redirects to new Request(destination, { method: "GET" }); the exact redirect-method/body conditions are not visible in the provided diff.
• 🟡 (10:26) fetchWithTimeout() was changed from native default redirect following to manual handling using redirect: "manual", rebuilding request headers for each validated redirect via prepareHeaders(request, undefined, token).
• 🔴 (10:26) User stated the retry loop’s final attempt always returns "done" or "throw"; the "retry" AttemptResult branch is unreachable on the last attempt.
• 🟡 (10:26) AttemptResult’s retry variant in packages/cli/src/lib/sentry-client.ts changed from { action: "retry" } to { action: "retry"; token?: string }.
• 🔴 (10:26) User stated post-mutation cache housekeeping never throws: a housekeeping failure must not convert a successful mutation into a failed command; helpers called by that code are already no-throw.
• 🟡 (10:26) Test environment key coverage was expanded to include SENTRY_FORCE_ENV_TOKEN and SENTRY_CUSTOM_HEADERS.
• 🟡 (10:26) Redirect/security test coverage was added or modified, including localhost-origin scenarios, invalid URL handling ("not a URL"), credential-forwarding rejection expectations, manual redirect behavior, and captured fetchCalls; exact test names and full assertions were elided.
• 🟡 (10:26) Assistant identified a regression in the initial redirect implementation: the retry loop must retain mutable headers modified by handleUnauthorized() after token refresh. Planned correction: preserve that invariant and derive redirect credentials from the mutable headers.
• 🟡 (10:27) packages/cli/src/lib/sentry-client.ts and packages/cli/test/lib/security/sntrys-claim-mismatch.test.ts were modified to correct the mutable-header/token-refresh regression.
• 🟡 (10:27) Focused test run passed: Vitest v4.1.10 in packages/cli; 1 test file passed and 14 tests passed; duration 6.64s (transform 4.38s, setup 170ms, import 3.90s, tests 2.17s, environment 3ms). Vitest emitted a deprecation warning that test.poolOptions was removed in Vitest 4 and prior poolOptions are now top-level options.
• 🟡 (10:27) Test execution logged that SENTRY_AUTH_TOKEN was detected but stored login for a stored OAuth user was used; SENTRY_FORCE_ENV_TOKEN=1 selects the environment token instead.
• 🟡 (10:27) Assistant reported the focused security suite passes with the redirect guard and began reviewing established retry, request-body, redirect, and custom-header coverage for contract preservation.
• 🟡 (10:28) Existing retry/body coverage is located in packages/cli/test/lib/sentry-client.test.ts, which describes authenticated-fetch retry and timeout behavior for CLI-1D6; relevant sections include describe("fetchWithRetry / buildAttemptFactory", ...) at line 38 and a 503 retry response at line 186.
