Security engineering

Find an ownership failure by changing one document identifier. Repair retrieval without breaking authorized shared reading.

Separate read access from editing authority. Verify denied writes leave the original document unchanged.

Test an operation whose button is hidden from members. Enforce role and team authority in the operation itself.

Repair a mass-assignment failure with explicit writable fields. Preserve protected state even when valid and protected edits are mixed.

Observe a real browser event handler executing at an unsafe DOM sink. Repair a plain-text feature and preserve its literal content.

Follow a saved comment into a later persona view. Repair the rendering boundary without deleting legitimate stored comments.

Change the structure of a query executed by real SQLite. Bind search values and verify quoted names still work.

Repair a scoped aggregate using trusted identity and real SQLite parameter semantics. Keep report totals and result shape stable.

Replace a client-supplied price with authoritative catalog calculation. Preserve mixed orders and reject invalid quantities.

Reproduce a duplicate order through sequential replay. Scope idempotency to actor and operation while preserving safe retries.

Trigger a malformed request and find a fictional configuration canary. Repair public errors while retaining local diagnostic handling.

Investigate a new revision endpoint, reproduce two policy failures, repair both boundaries and execute your own regression checks.

Investigate inherited-property behavior in a recursive merge. Repair key handling and preserve legitimate nested settings.

Separate cryptographic validity from authorization policy using actual Web Crypto and fictional signed capabilities.

Reproduce a stored-content chain into a fictional approval action. Repair the rendering and action boundaries independently.

Generate bounded inputs against an actual Wasm byte parser, minimize a failing case and repair its validated boundary.

Investigate synthetic event records and write a detection rule that separates unauthorized approval from legitimate activity.
