+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+   APPENDIX: How to apply the Apache License to your work.

+# jerboa-site Security Policy
+
+This repository is part of the Jerboa ecosystem. It contains public-facing site
+content and a deployable web binary, so publication requires both build evidence
+and content-sanitization evidence.
+
+Production claims require the release gates tracked by the Jerboa release plan
+and production-readiness inventory to be complete for this repository.
+
+## Supported Status
+
+No public production-support commitment exists yet. Security-sensitive releases must be cut from a clean checkout after:
+
+- `git status --short` shows only intentional release changes.
+- A secret scan is clean for the working tree and history review evidence is current.
+- `make verify` and `make release-evidence` pass.
+- SBOM/toolchain provenance is present under `dist/release-evidence/sbom/`.
+- The repeated-build report under `dist/release-evidence/reproducibility/` shows
+  `status=match`, or a release owner has recorded an explicit exception.
+- Deployment evidence is present under
+  `dist/release-evidence/deployment-evidence/`; promotion runs set
+  `JERBOA_SITE_REQUIRE_DEPLOYMENT_EVIDENCE=1`.
+- Dependency and native-code audits are clean, or accepted risks are documented.
+- `data/jerboa-source.json` contains sanitized public metadata only.
+- Private checkout paths, private hostnames, operational endpoints, and secrets are absent from release-visible content.
+
+## Security Expectations
+
+- Do not commit secrets, private keys, tokens, production `.env` files, operational hostnames, customer/user data, or private infrastructure details.
+- Keep source links on public HTTPS remotes.
+- Keep generated metadata sanitized by `tools/sync-jerboa`; do not publish local absolute paths or dirty-tree indicators.
+- Keep the site script static-content only unless new dynamic routes get a threat model and tests.
+- Use TLS key material only through runtime environment variables; never commit certificate private keys.
+
+## Remaining Blockers
+
+- Repeated clean binary builds must keep reporting `status=match` in
+  `dist/release-evidence/reproducibility/result.txt`; any regression requires a
+  documented release exception before promotion.
+- External review of public content and source links remains required before
+  public production support.
+- Deployment-header and TLS review proof remains required for promotion unless
+  `dist/release-evidence/deployment-evidence/status.txt` has
+  `deployment_review_proof_status=present`.
+
+## Reporting
+
+Before public release, report issues privately to the repository owner. After public release, replace this section with a dedicated advisory contact, supported versions, and disclosure window.

+# Content Security
+
+The checked-in site source is intended to be public-reviewable. Keep these rules
+in force before release:
+
+- Public remotes must use HTTPS URLs.
+- Generated metadata must use `"path": "jerboa"` and public remote
+  `https://git.sr.ht/~lisp/jerboa`.
+- Generated metadata must not publish dirty-tree state.
+- Do not publish local checkout paths, private hostnames, SSH remotes, private
+  infrastructure names, customer/user data, or operational endpoints.
+- Do not add inline JavaScript or event-handler attributes. The site CSP is
+  intentionally `script-src 'none'`.
+- TLS private keys and certificates are runtime deployment inputs only.
+- Deployment evidence must use HTTPS targets only, public DNS records, verified
+  TLS, and the checked security headers:
+  `Strict-Transport-Security`, `Content-Security-Policy`,
+  `X-Content-Type-Options`, `X-Frame-Options`, `Referrer-Policy`,
+  `Permissions-Policy`, `Cross-Origin-Opener-Policy`, and
+  `Cross-Origin-Resource-Policy`.
+
+Run:
+
+```sh
+make test
+make security
+make deployment-evidence
+```
+
+`make test` is the content-only gate. `make security` adds required-file,
+generated-artifact, and high-confidence secret checks.

+# Release Evidence
+
+Generate site release evidence with:
+
+```sh
+make release-evidence
+```
+
+The target writes `dist/release-evidence/` with:
+
+- `security.log` from the full release/content security gate.
+- `test.log` from the content-only public-safety gate.
+- `binary.log`, `binary-sha256.txt`, and `binary-linkage.txt` for the deployable
+  site binary.
+- `audit.log` with Jerboa and C compiler identity plus dependency-lockfile
+  status.
+- `sbom.log` and `sbom/` with toolchain identity, source/dependency hashes,
+  sibling `jerboa`/`jerboa-sinatra` Git state, Chez runtime artifact hashes, and
+  native archive provenance when available.
+- `reproducibility.log` and `reproducibility/` with two consecutive binary
+  builds, binary hashes, generated link-input manifests, linkage/load-command
+  data, and a bounded byte-diff sample when the binaries do not match. The
+  reproducibility job preserves the fixed `jerbuild binary` object directory so
+  the evidence captures the exact WPO payload and generated C inputs used for
+  the comparison.
+- `deployment-evidence.log` and `deployment-evidence/` with live target URL,
+  public DNS records, TLS verification, certificate metadata when `openssl` can
+  record it, HTTP status, security-header checks, public body checks, and
+  deployment-review proof status for the target in
+  `JERBOA_SITE_DEPLOYMENT_URL` (default `https://jerboa.sh/`).
+- `git-commit.txt`, `git-status.txt`, `diff-stat.txt`, `build-env.txt`, and
+  `source-sha256.txt`.
+
+`make deployment-evidence` is networked evidence. It records explicit
+`blocked-*` status fields when the target cannot be checked, while default local
+runs stay non-fatal so offline CI does not falsely claim production readiness.
+For promotion, set `JERBOA_SITE_REQUIRE_DEPLOYMENT_EVIDENCE=1`; any failed TLS,
+DNS, HTTP, header, or public-content check exits nonzero.
+
+Optional reviewed deployment proof can be attached with
+`JERBOA_SITE_DEPLOYMENT_REVIEW_PROOF_FILE=/path/to/proof.txt`. Set
+`JERBOA_SITE_REQUIRE_DEPLOYMENT_REVIEW_PROOF=1` when that proof is required.
+The proof must contain these exact markers and must not contain secrets, private
+hosts, or private checkout paths:
+
+```text
+deployment_header_review_status=reviewed
+tls_certificate_status=reviewed
+target_host_smoke_status=pass
+public_content_review_status=reviewed
+sensitive_artifact_policy=no-secrets-private-hosts-or-private-paths
+```
+
+A production promotion still needs clean reproducible-build evidence or an
+accepted release exception, plus external review of public content and source
+links.

+# jerboa-site Threat Model
+
+`jerboa-site` is a static public website packaged as a Jerboa HTTPS binary. The
+site source should be safe to publish, but it is still a network-facing service
+when deployed.
+
+## Assets
+
+- Public site content in `secure-site.ss`.
+- Generated public metadata in `data/jerboa-source.json`.
+- TLS certificate paths supplied at runtime through `TLS_CERT` and `TLS_KEY`.
+- Build and release evidence under ignored `dist/release-evidence/`.
+
+## Trust Boundaries
+
+- Site visitors are untrusted network clients.
+- Generated metadata imported from the core `jerboa` checkout is trusted only
+  after sanitization removes local checkout paths, SSH remotes, and dirty-tree
+  indicators.
+- TLS material is runtime-only and must never be committed.
+- `jerboa-sinatra` is a sibling source dependency and must be verified before the
+  site binary is promoted.
+
+## Required Posture
+
+- `make verify` and `make release-evidence` must pass from a clean checkout.
+- Release evidence must include SBOM/toolchain provenance and the repeated-build
+  reproducibility report. A `status=mismatch` reproducibility report is a
+  production blocker until fixed or explicitly accepted for a release.
+- Release-visible content must not contain private absolute paths, private
+  hostnames, SSH remotes, tokens, or private infrastructure references.
+- The site must keep a restrictive CSP with `script-src 'none'` unless a new
+  threat model and tests justify script execution.
+- Deployments must record TLS configuration, target host, binary hash, and smoke
+  evidence before public production support.
