Your message is delivered to João with no name attached — the page he reads only shows what you wrote, when, and which category. We don't store a database link from your message back to your member account on the inbox row.

However: a separate, tightly-scoped audit row does preserve your member identity, so that in cases of egregious abuse (threats, libel, spam) an admin can deliberately de-anonymize — and that lookup is itself logged. We don't do this casually. If you'd rather there be zero technical link, paste your message into a paper note and slide it under João's office door — that remains the most anonymous channel.

Non-retaliation pledge: you will not lose mat priority, coaching attention, or community standing for raising a concern through this channel — full stop. If you ever feel that's been violated, message João directly.
