+# Audit scope
+
+Written for an outside, independent security audit. Revision described:
+`c0e11da06565a812c7384982a2a14d8352325993` on `main`, 2026-10-31. Everything below is taken from the repository's own files at
+that revision; items marked NOT_RUN were not executed while writing this document.
+
+## What this repository is
+
+The source of the INTERPLANE website. A Cargo workspace with one crate, `crates/site-builder`
+(version 0.2.0, `publish = false`): `facts.rs` (488 lines) reads the protocol repository through
+`gh api`, `page.rs` (397) holds the copy and the Maud markup, `routes.rs` (67) names the six
+routes (Overview, Quick Start, Concepts, Adapter, Conformance, Status), `discovery.rs` (168)
+writes the JSON-LD block, `robots.txt`, `sitemap.xml` and `llms.txt` and checks them, and
+`main.rs` (362) has the `facts`, `build` and `verify` commands and tests. `public/` holds
+`style.css` and `hero.webp`. `scripts/sync-to-hub.sh` (71 lines) is the deploy job. `dist/` and
+`facts.json` are generated and ignored. Licence AGPL-3.0-or-later.
+
+## What to review, in priority order
+
+1. `crates/site-builder/src/page.rs`: every place a fact string is placed into markup. Maud
+   escapes `(expr)` by default. The one `PreEscaped` (`page.rs:74`) inserts
+   `discovery::script`: JSON-LD built with `serde_json`, with `&`, `<`, `>`, U+2028 and U+2029
+   written as `\u` escapes, inside one `<script type="application/ld+json">`. Check that escape
+   set, and attribute values and link targets built from facts (for example URLs that could
+   become `javascript:` or `http://`).
+2. `verify_html` and `verify` in `main.rs`, and `verify` and `json_block` in `discovery.rs`: the
+   rule checks that gate publication (exactly one inert JSON-LD block, no executable script, head
+   metadata equal to the generated route head). Check each AGENTS.md rule is enforced and cannot
+   be bypassed by unusual casing or encoding.
+3. `crates/site-builder/src/facts.rs`: `gh` and `gh_text` call `gh api` with arguments built from
+   the constant `PROTOCOL_REPO` and values read from earlier responses (commit sha, file paths);
+   Markdown parsers `status_counts`, `conformance_row`, `headline`, `stages`,
+   `public_description`; status selection by `SPARK_STATUS_CONTEXT`. `PROTOCOL_REPO` is
+   `aien-dev/interplane-mv`, the name AGENTS.md uses; it was `aien-dev/interplane` on `main`,
+   which only worked through GitHub's rename redirect, and this change asks for the real name.
+4. `scripts/sync-to-hub.sh`: skips while the machine's quiet flag is held, clones or fast-forwards
+   `main`, refuses a dirty checkout, builds with `cargo build -q --locked --release -p site-builder`
+   (`--locked` added by this change), falls back to the last good `facts.json` when `facts` fails, refuses on `verify`
+   failure, compares a `cksum` with the last published one, then `rsync -a --delete` to the web
+   host over SSH (excluding `.well-known`). `REPO`, `HUB`, `WEBDIR`, `LOGDIR` come from the
+   environment.
+5. `copy_dir` and `build` in `main.rs`: copying `public/` into the output.
+
+## Trust boundaries
+
+- Untrusted input: the protocol repository's README and status data as returned by the GitHub
+  API. Anyone who can merge there influences the page text.
+- Trusted: the `gh` login used by `facts` (AGENTS.md: it never writes a token), the deploy host's
+  SSH access to the web server, and `main` of this repository (merges publish within an hour).
+- Visitor side: the output is static HTML and CSS.
+
+## Threat model summary
+
+- Assets: integrity of the public site; honesty of the figures it shows; the deploy SSH key.
+- Attackers considered: hostile or mistaken text in the protocol repository; an unreviewed change
+  on `main`.
+- Defended: Maud escaping, `verify` rules before publication, refusal of dirty checkouts,
+  last-good-facts fallback.
+- Not defended / explicitly out of scope: the web server configuration, TLS for interplane.io and
+  the deploy host are outside the repository; `rsync --delete` mirrors whatever `build` produced.
+
+## Build from source at a pin
+
+Needs a stable Rust toolchain (version not pinned). Dependencies `maud` 0.26, `serde` 1,
+`serde_json` 1; `Cargo.lock` committed (18 packages).
+
+```sh
+cargo build --release -p site-builder
+```
+
+`site-builder facts` needs `gh`, logged in, and network access to GitHub.
+
+## Run every test
+
+NOT_RUN while writing this document. From AGENTS.md:
+
+```sh
+cargo test -p site-builder                       # renders a sample page and runs the verify rules
+target/release/site-builder facts                # needs gh login and network; writes facts.json
+target/release/site-builder build dist
+target/release/site-builder verify dist
+```
+
+Test attributes at this revision: 6 in `facts.rs`, 8 in `main.rs`. Expected: `test result: ok`.
+`scripts/sync-to-hub.sh`: do not run (AGENTS.md); it needs the deploy host and its SSH access.
+NOT_RUN.
+
+## Known limitations and NOT_RUN
+
+- Hosted CI (`.github/workflows/ci.yml`, added with this document) runs `cargo build --locked
+  --all-targets`, `cargo test --locked` and an SBOM job. It does not run `facts` or `verify`
+  against live data.
+- On `main` the deploy build did not pass `--locked` and `PROTOCOL_REPO` named the old
+  repository; both are corrected by this change (items 3 and 4 above).
+- Hosting, TLS and web server configuration are not in this repository.
+
+## Dependencies and provenance
+
+- `Cargo.lock` committed; crates from crates.io.
+- Build-time tools for the deploy: `git`, `cargo`, `gh`, `rsync`, `ssh`, `cksum`; versions not
+  pinned.
+- AGENTS.md: no Node build, no package manager besides Cargo; no GitHub Pages workflow or `CNAME`.
+
+## Evidence
+
+No signed receipts are stored in this repository; `evidence/` holds the `ONBOARDING-L642` and
+`discoverability-issue7` evidence sets. Every figure on the page names the protocol commit it was
+read at (AGENTS.md). The deploy job keeps its log and last facts outside the repository.

+# Security policy
+
+## Reporting a vulnerability
+
+Report privately. Do not open a public issue, pull request or discussion about it.
+
+Report vulnerabilities privately through the repository's Security tab, "Report a vulnerability",
+at https://github.com/aien-dev/interplane.io/security/advisories/new.
+
+Include the commit or release you tested, the component (path), steps to reproduce, and what an
+attacker gains. If the report involves a secret, say where it was exposed and do not send the
+secret itself. Do not post proof-of-concept payloads publicly.
+
+## Response targets
+
+This project has one maintainer; the targets below are best effort and stated honestly.
+
+- Acknowledgement: within 3 working days.
+- Triage and severity: within 7 days of acknowledgement.
+- Fix or mitigation for confirmed issues: aim for 30 days for high and critical, 90 days
+  otherwise, with a status update at least every 14 days until closed.
+- Disclosure: coordinated. An advisory is published with credit (unless you ask otherwise)
+  once the fix is on the default branch. Default embargo 90 days, negotiable.
+
+## Scope
+
+This repository builds the static INTERPLANE website. One Rust program, `crates/site-builder`,
+reads the protocol repository's public record on GitHub, writes the facts to `facts.json`, renders
+`dist/index.html` with Maud templates, and refuses a page that breaks the site rules.
+`scripts/sync-to-hub.sh` is the hourly deploy job.
+
+In scope:
+
+- Text from the protocol repository (README tables, descriptions, commit status contexts) that
+  reaches the page unescaped, injects markup or script, or produces a figure the protocol
+  repository does not record.
+- A page that passes `site-builder verify` while breaking a rule AGENTS.md lists: static HTML and
+  CSS only, no scripts, no outside fonts or trackers, no plain `http://` links, browser requests to
+  interplane.io only, the Spark verdict shown exactly as read.
+- `scripts/sync-to-hub.sh` publishing a dirty checkout, a page that failed `verify`, or anything
+  outside the build output.
+- Tokens or SSH material written to tracked files, `facts.json` or logs.
+
+Out of scope:
+
+- The protocol itself, which lives in its own repository; GitHub, the `gh` CLI, the web server
+  that hosts the site, and the host operating system.
+
+## Supported versions
+
+Only the default branch `main`, which is what the hourly job publishes. Reports against older commits are welcome but fixes land on the default branch only.
+
+## Status
+
+The live site is built from `main` by the hourly job (AGENTS.md). Hosted CI
+(`.github/workflows/ci.yml`) builds and tests the crate with `--locked` on pull requests and
+pushes to `main`. No certification, no bug bounty. See AUDIT_SCOPE.md for what to review and how
+to build and test it.
