 ### Assistant outcome
 The normal backend suite passed with 46 tests. Frontend and extension validation passed for all JavaScript syntax checks, JSON files, XPI rebuild, and unsigned XPI validation. The warnings-as-errors backend variant failed on unclosed SQLite connection `ResourceWarning` instances under Python 3.13; no functional tests failed.

-### Assistant outcome
-Added `Privacy.md` with a plugin-specific privacy validation covering manifest permissions, active-tab capture scope, local and session storage, outbound network destinations, Firefox `data_collection_permissions`, release validation, and residual privacy risks. Confirmed the signed XPI release metadata validates successfully and identified non-HTTPS backend support as the main remaining privacy caveat.

 ### Assistant outcome
 Added shared bearer-token dependencies, protected user configuration endpoints, restricted plugin administration to administrator accounts, and changed user configuration to use the authenticated user's ID instead of hard-coded `user-1`. The seeded `alice` account is an administrator for development and `bob` remains a standard user. README authentication guidance was added, and the strict backend suite passed with 8 tests.

+What are the fingerprinting risks of this system?

+### Assistant outcome
+Reviewed the public feed, authentication and link APIs, frontend, Firefox extension, Mastodon integration, configuration, and existing security audit. Identified high privacy risk from public link and profile metadata, plus medium risks from deployment/configuration fingerprinting, extension website activity, external-request attribution, and observable authentication behavior. No code changes were made.

 ### Assistant outcome
 Added the same live character-count warning to the Firefox extension popup: it fetches `/api/public/config` for the limit and the user's `/api/user/plugins/mastodon` post prefix, estimates the assembled Mastodon post length the same way as the New Entry page and backend plugin, and shows a localized `used/limit characters` counter (with an over-limit warning message) that updates on every relevant input and tag toggle. Added the `characterCount`/`characterCountOverLimit` translations to all five locale files (en-US, de, es, fr, nl) and verified all locale JSON files parse and `popup.js` passes a Node syntax check.

+Created `Privacy.md` with a source-grounded privacy and fingerprinting assessment covering public activity correlation, URL and query-parameter leakage, Firefox extension website activity, Mastodon correlation, server-side URL fetching, deployment fingerprinting, authentication observability, user guidance, and prioritized mitigations. Validated the document contents; no runtime code was changed.
