Notes and saved work

Save codes, tag references, keep private notes by code and effective period, highlight official notes separately from HCC Buddy guidance, and export a clean reference list.

Do not save patient names, member IDs, DOB, chart IDs, claim IDs, or pasted chart identifiers.

Saved work stays browser localStorage unless an authenticated account sync succeeds. Server-backed saved work remains release gated until migration review and export controls are approved.
