-- CS2 Skin Tracker — populate skin_conditions (per-skin wear tiers)
|
||
-- Run against the skintracker database as the app role.
|
||
-- Idempotent: re-running only inserts rows that don't exist yet.
|
||
--
|
||
-- The five CS2 wear tiers have fixed global float boundaries, but a
|
||
-- skin only appears in the tiers its own float range reaches, and the
|
||
-- achievable float within a tier is the intersection of the skin's
|
||
-- range with the tier's range. So for each skin we insert one row per
|
||
-- OVERLAPPING tier, with min/max clamped to that intersection.
|
||
--
|
||
-- Factory New 0.00 – 0.07
|
||
-- Minimal Wear 0.07 – 0.15
|
||
-- Field-Tested 0.15 – 0.38
|
||
-- Well-Worn 0.38 – 0.45
|
||
-- Battle-Scarred 0.45 – 1.00
|
||
--
|
||
-- Skins with no float bounds (e.g. Vanilla knives) get no rows.
