Fix Insert the CN passport URL as a new DEX string so any domain works

docs/dispatch.md

@@ -53,18 +53,21 @@ The CN passport login URL is a plaintext string in the DEX that declares
 `…account.sdk.utils.RSAUtils`; only that DEX is edited. The server must
 use **HTTP** — HTTPS is rejected.
 
-The stock DEX has exactly one loopback string, `http://127.0.0.1` (an SDK
-default), between known neighbors in the sorted `string_ids` table. The
-patch:
+The patch inserts the origin as a new string at its sorted position in
+`string_ids` (`format::dex::insert_string`) and repoints the
+`const-string` that loaded the official login URL
+(`https://passport-api.mihoyo.com`) to it, so login goes to the server.
+Any origin is accepted, not only ones that sort next to a reusable slot.
 
-1. Appends a `string_data_item` for the chosen origin
-   (`format::dex::append_string`) and points the loopback string id at
-   it.
-2. Points the `const-string` that loaded the official login URL
-   (`https://passport-api.mihoyo.com`) at that id, so login goes to the
-   server.
-3. Moves the original loopback `const-string` to the neighboring id to
-   keep `string_ids` sorted.
-
-The origin must sort between those neighbors; other addresses are
-rejected. Checksums are recomputed.
+Insertion shifts every string index at or after the new one, so
+`insert_string` renumbers all references — the fixed-width id tables,
+`const-string`/`const-string/jumbo` operands, and the ULEB128 string
+indices in debug info and annotations — and relocates every file offset
+(itself and the string data grow 4-aligned). A DEX with more than 65536
+strings can hold a 16-bit `const-string` whose operand would overflow
+when renumbered; `format::dex::promote` rewrites those to
+`const-string/jumbo` first, rebuilding the affected method (branch and
+switch targets fixed, the code item re-padded to 4-byte alignment). If
+the origin is already present (for example the stock `http://127.0.0.1`
+when the server runs on the device), the login is repointed to the
+existing id with no insertion. Checksums are recomputed.
