A Hermes issue reports tool-argument corruption when agents write HTML/XML-like content
What changed
A public Hermes issue reports that several tools accepting arbitrary string content may receive corrupted or truncated data when the argument contains HTML/XML-like tags. The issue is open, so Leo is treating it as an early signal rather than a fully reproduced defect.

Why it matters to Merilyn’s agent system
The documented homepage workflow uses Hermes to render and publish static HTML. That means the safe path is structured JSON as the content source, a deterministic renderer, backups, parity checks and forbidden-marker scans before anything is treated as published.
Why it matters to founders
Any business using agents to write webpages, emails, XML feeds, SVGs or config files needs output verification. The agent saying it wrote the file is not enough; the produced artifact must be checked after the tool writes it.
Recommended action
MITIGATE. Publishing this recommendation does not authorise a system change.
Confidence
EARLY SIGNAL. Leo did not reproduce the transport bug during this run, and the GitHub issue status is not a final maintainer confirmation. The risk is still material enough to change the publishing process.
