+# Deterministic per-iteration company names. Previously this used a random
+# generator (head -c 8 /dev/urandom | base64 | tr -dc 'a-zA-Z' | head -c 10)
+# producing names like "Company_<8-10 random alphas>_<i>", which differ
+# between record and replay runs of the Keploy http-postgres CI pipeline.
+# The postgres-v3 replayer matches mocks by bind value, so divergent random
+# names triggered intermittent "no invocation matched" errors on test-4 /
+# test-21 (the POST /companies inserts). A deterministic counter keeps
+# inserts unique within a single run while guaranteeing record/replay agree
+# byte-for-byte on the bind payload.
