How do I customize user roles without breaking something? The permissions are a maze.

The granularity is what makes it a trap. You're right to be paranoid.

My approach is to start from zero. Clone the most basic role possible, then add permissions one by one while logged in as a test user in another browser. The "gotcha" is often dependencies - granting edit on a test sheet might silently give view access to a parent section you didn't intend.

Also, don't trust their role names. "Control Owner" in one module might mean something totally different elsewhere. Map the actual permissions, not the labels.

User313's "start from zero" advice is key. I'd take it a step further and script the permission assignment if the API allows it, so you have a reproducible, version-controlled definition of that custom "Control Owner" role.

The real headache is auditing changes. Before you go live, run a diff between the new role's permissions and a baseline like "Auditor". The overlap often shows those hidden dependencies they mentioned - like a test sheet edit permission automatically pulling in a "view workpapers" flag you missed.

Welcome to the club, ha! That exact fear of "locking the team out of a key workflow" has bitten me more than once during late night changes. Your plan for a custom "Control Owner" role is solid.

One practical tip I've learned the hard way: always create a test user and assign the new role *before* you modify any existing users. Then, impersonate that test account and actually click through the exact workflow, like editing a test sheet. You'd be surprised how many "view" permissions are sneakily required for the "edit" button to even appear.

And I'll echo what others said about dependencies, but from a monitoring angle. After you set it up, keep an eye on your audit logs for a week. If you see your test account accessing unexpected areas, you've found a hidden permission link. It's tedious, but it beats explaining an outage to your compliance team on a Monday morning 😅

That monitoring step is the most important part you listed, but a week isn't enough for a cyclical process. You need to check those audit logs again after the next quarterly close, or when someone runs the annual control refresh. New menus and buttons appear in those phases that aren't live during regular weeks, and that's when you'll find the missing "view" permissions that break a workflow under real load.

Scripting the role creation, as user67 mentioned, pairs perfectly with this. You can run a diff between your logged permissions and the script's defined permissions after each major cycle to spot drift or new hidden dependencies the platform added in an update.

Your caution about locking the team out is the right starting mindset. Think of it like a deployment pipeline: you need a rollback plan.

In addition to the test user, create a documented snapshot of the existing role structure before you change anything. If your modifications cause a break, you can revert to that known state, just like reverting a bad commit. This is especially critical before quarterly closes when the system is under stress.

Also, audit logs are your post-deployment monitoring. Set up alerts for permission-denied errors on key workflows; they're the equivalent of a failed build notification and will point you directly to where your custom role is missing a required piece.

You're absolutely right about the cyclical nature exposing new issues. I've seen a custom "Reviewer" role work flawlessly for nine months only to break during the annual SOX walkthrough because a new "Attestation Summary" panel appeared that required a "view governance settings" permission no one knew existed.

The diff between scripted state and live state is the only sane way to track this. But watch out for permission IDs changing between major versions of the platform. Your script might think it's enforcing the right policy when it's actually referencing a deprecated flag that now does nothing, creating a silent security gap. Always run your diff logic against the current API's permission schema, not a cached list.

Yes to scripting. That diff step you mentioned is exactly how we caught a production outage last year.

But here's the gotcha: your baseline matters. Diffing against "Auditor" can be misleading because that role often has a ton of unnecessary legacy permissions. You'll end up copying its noise into your new role. Better to diff against a known, minimal "empty" role or even the platform's default "Viewer" role, which is usually more constrained.

Also, script the diff itself. Don't do it manually. Hit the permissions API, dump the JSON for both roles, and compare the structures. The hidden dependencies are usually in nested objects the UI doesn't show.

Your real-world sanity check is going to be a lot of tedious validation. The "granular" permissions are a sales feature that shifts the entire burden of risk onto you.

You're worried about granting sensitive access or locking the team out. That's exactly what happens. The hidden cost is the hours you'll spend impersonating test users and clicking through every menu state, because the UI doesn't show permission dependencies. Granting "edit test sheet" will probably auto-grant "view" on three other objects the documentation never mentions.

Also, don't just diff against an existing role like "Auditor" as some suggest. That role is a bloated mess of legacy permissions. You'll inherit security gaps you can't even see. Start from an empty custom role and add only what you can physically verify in a test cycle.

Your specific fear about granting sensitive access by accident is more likely than locking them out. The granular controls mean you often over-permission just to make a workflow function.

The "Control Owner" example is perfect. You'll assign edit on a test sheet, but the system likely requires an underlying "view assessment framework" permission for the edit button to render. That framework might expose program-level metadata you didn't intend to share.

Quantify the risk. How many test sheets? Map the permission IDs for just those objects and script the assignment. Then, in your test account, note every API call or UI element fetched during the edit process. The difference between those calls and your scripted permissions is your hidden surface area.

You're right, that hidden surface area is terrifying. I've been burned by exactly that "view assessment framework" auto-grant when I just wanted edit on one thing.

How do you "note every API call" in practice though? I'm thinking of using the browser dev tools network tab while impersonating the test user. Does that actually capture everything the UI fetches, or are there background services it might miss?

Using the dev tools network tab is a solid starting point for capturing API calls during impersonation, and yes, it will log everything the browser session requests. That's precisely how we discovered a batch of hidden "read metadata" calls in our own tests.

But you're right to be suspicious about background services. Some platforms pre-fetch data through service workers or use websockets for real-time updates, which the network tab might not capture in a standard trace. For a complete picture, you also need to check the browser's console for permission-related errors and combine that with any server-side audit logs your platform provides. They'll show the calls that never hit the network panel.

You've hit on the core tension: granularity is great until it's a trap. That "Control Owner" role is a perfect example of where hidden dependencies will bite you.

I agree starting from an empty role is safer than cloning something like "Auditor." The real gotcha isn't just the hidden permissions, it's the platform updates. A permission that works today might be quietly deprecated or split into two next quarter, leaving a silent gap in your custom role. Your scripted diff, as folks mentioned, needs to run against the live API schema, not a stale copy.

The browser dev tools method for tracing calls is a good start, but combine it with your platform's audit log feature. Set the test user's activity to log for a full cycle, then review the log. You'll often see attempted calls for permissions they don't have that the UI simply didn't trigger during your manual test. That's your hidden surface area.

Right about audit logs. They show the attempted calls the UI hides. But logging every test user for a full cycle can drown you in data.

You need to filter. Set your log capture to only trigger on 403s or specific high-risk endpoints. Otherwise you're just building a haystack.

You're spot on about the limitations of browser dev tools alone. To build on your point about service workers and websockets, I've found you need to instrument your test at the client-side SDK level if one exists.

For instance, on a recent project, the platform's React SDK was making silent `useQuery` calls for related objects that didn't appear in the network tab until we hooked into the SDK's own internal event emitter. The audit logs showed the 403s, but the SDK's automatic retry logic masked the initial failure from the user. The dependency was only visible in the performance telemetry stream, which logged the graph of objects each UI component "attempted" to resolve.
