therealaleph cbb08468bc fix: v1.9.6 — Code.gs/CodeFull.gs hardening, goog.script.init unwrap, README rewrite
Server-side (Apps Script) fixes — users replace their Code.gs with assets/apps_script/Code.gs (or CodeFull.gs for full mode) and Manage deployments → ✏️ → New version → Deploy:
- Removed duplicate doGet in Code.gs (HtmlService one was overriding ContentService one due to JS hoisting → every GET to /exec returned a goog.script.init iframe instead of the placeholder HTML)
- CodeFull.gs doGet switched from HtmlService to ContentService (same reason)
- SKIP_HEADERS now strips X-Forwarded-* / Forwarded / Via family — second line of defense to v1.2.9's client-side stripping (#104), in case a misconfigured upstream proxy adds these
- _doBatch fallback when UrlFetchApp.fetchAll() throws as a whole — per-item fetch on safe methods so one bad URL no longer poisons the entire batch (port from masterking32@3094288)

Client-side (Rust) defense-in-depth:
- parse_relay_json now unwraps goog.script.init("...userHtml...") if any deployment returns the iframe-wrapped form (legacy Code.gs, or a redirect that GETs doGet). New extract_apps_script_user_html + decode_js_string_escapes helpers. Tested against a real deployment's doGet response.

Docs:
- README rewritten as short bilingual landing page (English + Persian RTL) targeting normal users; advanced reference moved to docs/guide.md + docs/guide.fa.md.

Tests: 3 new regression tests. 176 lib + 33 tunnel-node tests passing.

Apps Script source

Three deploy-ready Apps Script files live here. They all speak the same {k, m, u, h, b, ct, r} wire protocol with mhrv-rs, so the client just points its script_id at whichever deployment you want — no mode change required.

Variants and origins

  • Code.gs — standard relay. Verbatim mirror of upstream. Apps Script does the outbound fetch itself. This is the default choice for most users.

  • CodeFull.gs — superset of Code.gs that additionally proxies raw-TCP / UDP via tunnel-node (used by mode: "full"). Maintained in this repo — written for this Rust port and not present upstream. Deploy this if you want full-tunnel mode; details in the file's header comment.

  • Code.cfw.gs — Apps Script becomes a thin auth+forward layer; the actual outbound fetch happens on a Cloudflare Worker you also deploy (assets/cloudflare/). Derivative work — not unmodified upstream. The pattern of forwarding through a Cloudflare Worker came from denuitt1/mhr-cfw; this file inherits hardening from Code.gs (decoy-on-bad-auth, fail-closed sentinels) and adds chunked batch forwarding (Promise.all on the Worker side, ceil(N/40) GAS calls per batch) that the upstream mhr-cfw does not have. Faster per-call latency, worse YouTube long-form, no fix for Cloudflare anti-bot. Read assets/cloudflare/README.md before choosing this one.

What you must edit before deploying

For every variant: change AUTH_KEY from its placeholder to a strong secret, and use that same string in your mhrv-rs config's auth_key. Code.cfw.gs additionally requires setting WORKER_URL to your deployed Cloudflare Worker URL; CodeFull.gs additionally requires TUNNEL_SERVER_URL and TUNNEL_AUTH_KEY for the tunnel-node leg.
