Why this matters

In ods/extensions/services/dashboard-api/pixel_chat_identity.py, asks_display_name(messages) accesses text = messages[-1].content and immediately invokes len(text). When the last message has None content or structured multimodal content (such as a list of image/text parts), Python raises a raw TypeError: object of type 'NoneType' has no len() instead of returning False.

This surgical fix verifies isinstance(text, str) before checking length and normalizing unicode text.

Validation

• Baseline reproduction: verified that content=None crashed with TypeError on baseline.
• Post-fix behavior: cleanly returns False.
• Telemetry: pixel-chat suite: 1 passed. New-test syntax and diff checks pass; new regression wired into Linux CI.

Overlap check

Inspected open/closed PRs. PR #5808 checked owner_namespace whitespace; zero overlap with display name message inspection.

Risk / AI disclosure

AI-assisted investigation, patch, and regression tests. Enforces robust content handling on identity recognition. Independent review remains a gate.

Follow-up integration evidence

Composed locally with public-beta at 6a408cc85 without conflicts. CI and unit checks pass.
