Cognitive liberty is not only a legal promise. It is an architecture. Prompt logs, pasted system summaries, private drafts, legal questions, browser diagnostics, source records, and persona files become surveillance surfaces when they are sent to remote systems by default.
The browser-local reports show a practical path: deterministic rules, local storage, service workers, WebAssembly, local vector search, finite-state matching, and optional local models can produce serious triage without turning every prompt into a server-side record.
No prompt leaves by default.

Recommended approach
Cognitive-liberty reason
Input
Sanitize and process in browser memory.
Avoid unnecessary disclosure of private notes.
Pattern detection
Deterministic dictionaries and finite-state matching.
Make classification inspectable.
Semantic search
Local embeddings or precomputed vectors.
Avoid remote inference over sensitive text.
Rules
Deterministic JSON/YAML rule engine.
Keep the model from becoming the judge.
Storage
IndexedDB, OPFS, SQLite-Wasm, export packets.
User-held records and rollback.
Network
Opt-in only, visible payload preview.
Consent must be specific and revocable.
A probability score is not justice, and a classifier is not conscience.
Design prohibition
A local diagnostic may evaluate a use case, system risk, route, or artifact. It must not create a hidden user profile, moral score, future-danger label, trustworthiness grade, or reportable-topic record.
If remote assistance is enabled, the system should show exactly what will be sent, redact where possible, retain a local audit record, and provide a permanent off switch.
