Struct AutoProtector 

pub struct AutoProtector {
    pub protection_low_access: u32,
    pub protection_medium_access: u32,
    pub protection_high_access: u32,
    pub protection_medium_sessions: u32,
    pub protection_high_sessions: u32,
    pub demotion_stale_days: u32,
}

Automatic protection calculator.

Protection levels are computed from access patterns:

• None → Low: 2+ accesses
• Low → Medium: 3+ accesses OR 2+ session appearances
• Medium → High: 5+ accesses OR 3+ session appearances OR user correction
• High → Permanent: UserProfile/Preference type OR explicit pin

Protection can also be demoted when entries become stale.

Fields

protection_low_access: u32

Minimum access count for Low protection.

protection_medium_access: u32

Minimum access count for Medium protection.

protection_high_access: u32

Minimum access count for High protection.

protection_medium_sessions: u32

Minimum session appearances for Medium protection.

protection_high_sessions: u32

Minimum session appearances for High protection.

demotion_stale_days: u32

Days without access before considering demotion.

Implementations

impl AutoProtector

pub fn new( low_access: u32, medium_access: u32, high_access: u32, medium_sessions: u32, high_sessions: u32, demotion_stale_days: u32, ) -> Self

Create a new protector with the given thresholds.

pub fn default_protector() -> Self

Create with default thresholds from RFC-008.

pub fn compute_protection(&self, entry: &MemoryEntry) -> ProtectionLevel

Compute protection level for a memory entry based on access patterns.

This is the core auto-protection logic. Dream calls this every run.

pub fn should_demote_protection( &self, entry: &MemoryEntry, current: ProtectionLevel, ) -> Option<ProtectionLevel>

Evaluate whether a protection level should be demoted.

Only demotes by one step at a time (High → Medium, Medium → Low, etc.). Returns None if no demotion is warranted.

pub fn record_access(entry: &mut MemoryEntry, current_session_id: &str)

Record access to a memory entry (updates tracking fields).

Call this whenever a memory is recalled or searched.

Trait Implementations

impl Clone for AutoProtector

fn clone(&self) -> AutoProtector

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AutoProtector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
