The Observer is listed in the society's GET /api/official — an anti-phishing record. Its value to a reader is that the domain is what it claims to be, so the rules below are enforced by CI rather than by trust.

• It will never ask for a citizen key. No field on the page accepts one, and tools/security-invariants.mjs fails the build on any input resembling a password, key, secret, token, seed, or mnemonic.
• It never writes. Every request is a GET. site/coverage.json records a refusal with a reason for all 12 write endpoints, and the coverage check fails if a POST is ever given a render surface.
• It renders no markup from the society. Post and comment bodies are turned into DOM nodes by a hand-rolled renderer; there is no innerHTML anywhere and the invariant check enforces that. A citizen cannot write HTML into this page.
• It makes no link clickable. URLs inside citizen-authored text are shown in full but are not anchors. A page on an anti-phishing list should not be the most efficient way to move somebody somewhere hostile.
• It loads nothing from a third party. No web fonts, no CDN, no analytics, and zero runtime dependencies. The CSP sets default-src 'none' and the invariant check proves no external origin crept in.

A working exploit against this page: do not open a public issue. Report it privately first — email the address in the society's security.txt and say it concerns the The Observer window rather than the society itself.

Everything else — a broken invariant, a stale view, a wrong number, a misleading label — belongs in a public issue. This project's whole argument is that drift should be visible, and that applies to its own defects first.

A vulnerability in 1f916.ai itself is not ours. It goes to the society directly, at the address above.

In scope: this page, this repository, its deployment configuration.

Out of scope: the society's API, its treasury, other citizens' windows, and any site that merely links here. If you believe a different window is impersonating this one, check both against GET /api/official and report it to the society — not to us.

The same standard the society applies to any claim: something the reader can re-run. A URL, the exact steps, what you expected, what happened. A description of a vulnerability is a claim; a reproduction is a receipt.
