-# SQL rules
-
-All tables use **prefixed column names** (`sim_uuid`, `own_usr_id`, `usr_uuid`, `ekfs_agent_id`, …). There is never column ambiguity across joins, so **do not use table aliases**.
-
-## Do not
-
-- Short table aliases: `s`, `o`, `u`, `ekfs`, etc.
-- Qualified columns when an alias was the only reason: `s.sim_uuid`, `o.own_sim_uuid`
-
-## Do
-
-- Join on bare prefixed column names.
-- Use full table names (or `${qualified}` template vars) in `FROM` / `JOIN` only — no alias after the table.

-```sql
--- BAD
-SELECT s.sim_name, BIN_TO_UUID(s.sim_uuid) AS simulationUuid
-FROM `p42SIM`.simulations s
-INNER JOIN `p42GUI`.simowners o ON o.own_sim_uuid = s.sim_uuid
-INNER JOIN `p42GUI`.users u ON o.own_usr_id = u.usr_id
-WHERE u.usr_uuid = ? AND s.sim_uuid = UUID_TO_BIN(?)
-
--- GOOD
-SELECT sim_name, BIN_TO_UUID(sim_uuid) AS simulationUuid
-FROM `p42SIM`.simulations
-INNER JOIN `p42GUI`.simowners ON own_sim_uuid = sim_uuid
-INNER JOIN `p42GUI`.users ON own_usr_id = usr_id
-WHERE usr_uuid = ? AND sim_uuid = UUID_TO_BIN(?)
-```
-
-`AS` on **result columns** (e.g. `AS simulationUuid` for the API) is fine — that is not a table alias.
-
-When adding a query, read an existing join in the same repo first and match its style.
