Summary

• Hash Langfuse userId and sessionId into privacy metadata, remove raw identity fields from sanitized raw span payloads, and stop promoting raw identities into normalized span attributes.
• Enforce a minimum env HMAC salt length, surface missing/weak salts in doctor, and warn on every config-loading CLI command when privacy.store_raw_io is enabled.
• Create .agentprof/.gitignore during agentprof init and refresh README examples to export a sufficiently long salt before doctor and imports.

Review

• Self-review found raw identity fields still persisted in sanitized raw spans; fixed by removing userId/sessionId after hashing and adding import-level coverage.
• Self-review found doctor would break older workspaces missing .agentprof/.gitignore; fixed by keeping .gitignore creation in init without making it a doctor requirement.
• Final review found normalization still fell back to raw sessionId; fixed so normalized session IDs come only from session_hash.
