+● Good commit — all four issues are now addressed. A couple of small things to note:
-  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).
+  The "uniform" wording on dynamic reflectivity is slightly off. The note you added says the dynamic reflectivity
-  int32_t police_boat  // no semicolon
+  "is to be passed to the shaders as a uniform," but reflectivity is a field inside
-  int type             // no semicolon
+  target_data_to_shader_structure, which goes through the SSBO — not a uniform. The correct statement is: the
-  Would be compile errors in real code.
+  dynamic (glint-fluctuated) value is computed at SSBO write time and packed into the SSBO struct's reflectivity
-  
+  field. It never gets written back to the database. The intent is right, just the word "uniform" is misleading
-  4. binary may_need_update in the database schema (line 1001) is still not a proper type.
+  here.
-  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.
+  Minor formatting issue in the database workflow — step 4 appears twice (once as 4 and once as 4a/4b), and step 6
-  A PostgreSQL TIMESTAMP stores a calendar date+time (e.g., 2026-05-28 14:30:00), not a count of elapsed seconds.
+   describes two actions (INSERT + run getMaterialProfile()) that might read more clearly if the derivation step
-  If the intent is seconds-since-epoch, the column type should be BIGINT (and the name elapsed_seconds makes
+  comes before the INSERT, since you'd want the derived values computed before writing the new record to
-  sense). If the intent is an actual timestamp, use TIMESTAMP and name it last_seen or similar. The current
+  PostgreSQL.
-  combination is confusing.
 
-  ---
+  Neither of these affects implementation — any developer reading it will understand what you mean. But if you
-  Minor
+  want to tighten the wording before moving on to the simulator, those are the two spots worth a quick pass.
-
+  Otherwise the traffic cop spec is complete and you're good to proceed.
-  - 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.
