Summary

• Profile picker: the Flow Neuro page has a picker for the running profile and the other profiles that sync with linked devices (?profile= in the route).
• Another profile, read only: it shows the same persona components, fed a brain, persona and music taste read from that profile's own database on this computer.
  • The new command get_profile_interests opens the database with open_closed and reads without writing. Nothing is loaded into the resident brains.
  • Nothing goes to the server.
• No editing in read-only mode: unblocking, blocked music artists, learning activity, import, export and reset are hidden. BlockedContent hides its unblock buttons when no handler is given.
• Shared logic, not copies:
  • services::profile_interests::stored_interests computes from a brain value with the existing classify_persona and taste_profile.
  • PersonaDetails moved there and get_flow_persona uses it.
  • The music store's reader became stored_brain and is shared. FlowNeuro gets a read-only stored_brain.
• Dashboard link: each synced profile row on the Dashboard links to View interests. The Dashboard itself shows none.

Change type

• Bug fix
• Feature
• Refactor or maintenance
• Documentation
• Build, packaging, or CI

Validation

Run on the head of this branch (91dc5e2), in its worktree with the shared Cargo target dir:

• pnpm test: 191 files, 1105 tests passed
• pnpm build: passed
• cargo fmt --manifest-path src-tauri/Cargo.toml --all -- --check: clean
• cargo clippy --manifest-path src-tauri/Cargo.toml --all-targets --all-features: finished; every warning it prints is on a line older than this stack (checked with git blame)
• cargo test --manifest-path src-tauri/Cargo.toml --all-targets --all-features: 1118 passed, 0 failed, 9 ignored
• I smoke-tested the affected desktop behavior.

New tests:

• services::profile_interests: a stored brain is shown as stored and left untouched; a profile without brains shows fresh ones and stores nothing.
• src/lib/linked/interestChoices.test.ts: which profiles the picker offers.

Screenshots or recordings

Risk and compatibility

• No migration. Reading another profile opens its database for a moment and closes it; nothing is written.

• Another profile's view uses its stored brain as last saved, without the tidy-up the running profile applies when it loads.

• No new secrets, private data, telemetry, or broad Tauri permissions were introduced.

• User-facing documentation was updated where needed.

• Dependency and lockfile changes are intentional and limited to this PR.

• Breaking changes and upgrade steps are clearly documented.
