Subject: [PATCH] Fix latenten Flake in links.service.db.test
 (Phantom-Sortierung)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

pondGraph-Test sortierte die EMPFANGENEN Phantom-Slugs, verglich aber
gegen ein UNsortiertes Literal. Da beide Slugs (ghost-<sfx>,
ghost-secret-<sfx>) den Zufalls-Suffix teilen, kippt ihre Sortierreihen-
folge auf ~1/5 der Suffixe (wenn sfx[0] > 's') → nicht-deterministischer
Fehlschlag. In CI-Lauf 372 traf es zu (Suffix „vpxwe…"). Fix: beide
Seiten sortieren. Vorbestehender Bug, unabhängig von M17–M19.
