  Still Needs Attention
  
  1. float altitude is now listed twice in target_data_structure (lines 130 and 136).
  float altitude; // in meters          ← line 130, was originally "float height"
  ...
  float altitude; // meters, but 0 for boats  ← line 136
  It looks like the original float height (structural height of the vessel) got accidentally renamed to altitude,
  creating a duplicate. The structural height of the vessel is a distinct concept from flight altitude. float 
  height should be restored at line 130, or the duplicate removed if structural height is intentionally dropped
  from the structure.
  
  2. getMaterialProfile parameter still mismatches the switch.
  The function signature is getMaterialProfile(int aisTypeCode) but the switch operates on vessel_type. In actual
  C++ code, vessel_type would be out of scope inside the function — the parameter would need to be named
  vessel_type, or the switch would need to use aisTypeCode. Minor, but would cause a compile error.

  3. Missing semicolons on the last two SSBO struct fields (lines 154–155).
  int32_t police_boat  // no semicolon
  int type             // no semicolon
  Would be compile errors in real code.
  
  4. binary may_need_update in the database schema (line 1001) is still not a proper type.
  int32_t police_boat was correctly fixed, but may_need_update still uses binary. In PostgreSQL this should be
  BOOLEAN or SMALLINT. Should be consistent with police_boat.

  5. timestamp elapsed_seconds — the name and type contradict each other.
  A PostgreSQL TIMESTAMP stores a calendar date+time (e.g., 2026-05-28 14:30:00), not a count of elapsed seconds.
  If the intent is seconds-since-epoch, the column type should be BIGINT (and the name elapsed_seconds makes
  sense). If the intent is an actual timestamp, use TIMESTAMP and name it last_seen or similar. The current
  combination is confusing.

  Minor

  - Line 1185: typo "shouse" → "should"
  - The unresolved architectural question from before (does traffic_cop filter for the currently active scope
  only, or does it maintain separate lists per radar?) is still implicit. This may become clear once the simulator
   section is written, so it may not need addressing now.
