Extend the upload validator to accept .tar.gz/.tgz, .tar.zst, and
.tar.xz archives alongside raw .html and .zip. Upload-kind dispatch is
now magic-byte sniffing (detect_kind) rather than trusting Content-Type,
matching the module's never-trust-the-archive posture.
build_tar_manifest reuses every zip-path structural and size rule
(path-traversal checks, dedup, entry cap, root index.html requirement).
The streaming zip-bomb defense is preserved end-to-end: gzip/zstd decode
lazily as each tar entry is read, and one-shot xz decompresses into a
size-bounded LimitedWriter so a bomb aborts mid-decompress. All decoders
are pure Rust (flate2 rust_backend, ruzstd, lzma-rs) and the tar crate
compiles cleanly for wasm32-unknown-unknown; bzip2 is intentionally out
of scope.
Frontend accept list and Content-Type helper updated; the backend now
sniffs the real format so archives are sent as application/octet-stream.

Micro static-site host running entirely on Cloudflare: a Rust->wasm
Worker (workers-rs 0.7 + axum 0.8) serving user-uploaded .html/.zip
content from R2 at pages.elijah.run/<slug>/, with D1 for users/
sessions/page metadata and GitHub OAuth for login. Admins approve
uploaders, delete pages, and can mark pages/users trusted.
Security design (docs/plans/2026-07-12-pages-design.md): hosted
content is served with a CSP sandbox (opaque origin — no cookies or
storage, cannot make credentialed /api calls) unless admin-trusted;
strict slug grammar + reserved names; streaming zip validation
(traversal, bombs, size/entry/depth limits); SHA-256-hashed session
tokens in __Host- cookies; Origin checks on all mutations; upload
quotas and size caps.
Includes OpenTofu infra (R2, D1, DNS; wrangler owns the Worker
deploy), an embedded single-file management UI, deployment guide,
and 148 native unit tests + 18 doctests (clippy -D warnings clean on
native and wasm32). Deployed and verified in production.
Squash of 15 commits from pages-v0: each ticket implemented by a
Claude Sonnet agent, reviewed by a Claude Opus agent, tracked with
beans (pages-lxjz..pages-shqc).
