Fixture redaction strings remain fake test data. | | Sensitive Data Exposure | PASS | -- | Browser schema exposes capped sparkline points and public download delta context only; no snapshot paths or private archive contents are exposed. | | Insecure Dependencies | PASS | -- | No dependencies added or changed. | | Security Misconfiguration | PASS | -- | Snapshot paths remain confined and atomic writes still assert paths stay inside the snapshot directory. | ### Findings No security findings. *** ## GDPR Compliance Assessment ### Overall: N/A *N/A because this session introduced no personal data collection or processing.* | Category | Status | Details | | -------------------------- | ------ | ------------------------------------------------------------------------------------------------------- | | Data Collection & Purpose | N/A | Uses existing public evidence timestamps and public Hugging Face model download metrics. | | Consent Mechanism | N/A | No new personal data is collected. | | Data Minimization | PASS | Browser projection is capped to 14 sparkline points and bounded download delta fields. | | Right to Erasure | N/A | No new personal data storage path. | | PII in Logs | PASS | New collector logs report counts and states only, not user identifiers, private paths, or raw archives. | | Third-Party Data Transfers | N/A | No new source, credential, or outbound transfer path introduced. | ### Personal Data Inventory No personal data collected or processed in this session. ### Findings No GDPR findings. *** ## Recommendations None - session is compliant. *** ## Sign-Off * **Result**: PASS * **Reviewed by**: AI validation (validate) * **Date**: 2026-06-12 --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase27-session04-daily-time-series-persistence-and-sparklines/security-compliance.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
