A daily recitation by Apothecary agents secretly implants a crawler with an unknown upgrade while preserving plausible deniability.
For months, the Apothecary has forced agents to repeat a mantra containing known errors and half-truths. The misinformation protects any observing crawler from showrunner retaliation.
The visible message is only cover. Its actual function is to install an upgrade in a crawler who witnesses it.
Agatha does not know the upgrade's nature or purpose but assumes it threatens the Eulogist and plans to neutralize it if acquired.
A spoken mantra forming harmless false words outside and a concealed upgrade sigil inside a viewer.
The implant is the Apothecary's covert route to influencing crawlers and the system AI.
