Why this matters

In ods/extensions/services/dashboard-api/pixel_chat_results.py, owner_namespace(credential) hashed input credentials without validating non-empty, trimmed strings. Consequently, empty strings or credentials with trailing whitespace were hashed into valid 64-character hex namespaces, creating split result stores for the same logical owner.

This surgical fix verifies credential and credential == credential.strip(), raising ValueError("invalid-owner-credential") on malformed credentials.

Validation

• Baseline reproduction: verified that owner_namespace("") and owner_namespace(" owner ") produced hashes without error on baseline.
• Post-fix behavior: properly raises ValueError("invalid-owner-credential").
• Telemetry: pixel-chat suite: 3 passed. New-test syntax and diff checks pass; new regression wired into Linux CI.

Overlap check

Inspected open/closed PRs. PR #5745 guarded project receipts; zero overlap with chat result namespace hashing.

Risk / AI disclosure

AI-assisted investigation, patch, and regression tests. Guards owner isolation namespaces against credential padding. Independent review remains a gate.

Follow-up integration evidence

Composed locally with public-beta at 4fa6ad170 without conflicts. CI and unit checks pass.
