Go and Python fixed; Rust/TS confirmed already correct. - Validate the download_url scheme: https always, http only for loopback or an http registry base; reject everything else (incl. file://). - Cap the artifact read at declared-size + slack, ceilinged at 100 MiB, to prevent an OOM from a hostile/oversized body. - Add connect+read timeouts (default 30s) to every SDK's HTTP client.

charset=UTF-8 Content-Transfer-Encoding: 8bit This repo is polyglot — one library, many language clients. Rather than publishing a single fat artifact (which would make e.g. a Java consumer download the Node sources), each [targets.] publishes as its own package `/-` at this single shared version, so a consumer installs and downloads only the language it uses. Consumers depend on the language package directly, e.g. "/-java" = "^0.1" or let zed infer the target from the project (package.json -> nodejs, go.mod -> golang, pom.xml -> java, ...).

Targets whose ecosystem zed cannot wire keep no adapter: they still install into zed_modules/ and are listed in .zed/paths.json. The zed-package gate additionally asserts every *language* artifact declares a concrete `language`, which is what lets a consumer install refuse e.g. the -java slice in an npm-only project. `[targets.repository]` is exempt: it is the whole-repository release surface (doc 18), language-agnostic by construction and correctly ungated.

Add four new SDKs implementing the same contract (getPackage, getVersion, search, claimOrg, yank, sha256-verified downloadArtifact with the https/loopback download-url policy and the 100 MiB + slack size cap, and multipart publish, with typed ApiError codes): - clients/wasm: Rust -> WebAssembly via wasm-pack (wasm-bindgen + global fetch), reusing the zed-interfaces DTOs; pure logic unit-tested on the host target. - clients/dart: package:http transport, streamed size-capped downloads, MockClient tests. - clients/gleam: gleam_httpc transport behind an injectable Transport, gleeunit tests. - clients/erlang: stdlib-only (httpc + OTP 27 json + crypto), eunit tests including round-trips against a one-shot loopback server. Update .zpkg.toml targets for the new layout (including the golang.native subdirectory tag format) and add rust-wasm, dart, gleam and erlang targets; verified with the pinned zed-cli: pack produces the repository artifact plus 8 language slices and the zed-package interop checks pass, as does publish --dry-run. Extend ci.yml with wasm, dart, gleam and erlang jobs and point every job at clients/.

Preserve gateway prefixes, refuse redirects, separate registry bearer credentials from artifact hosts, bound diagnostics, register Maven/Swift Zed targets, and pin the read-only ten-language matrix.

Subject: [PATCH 107/144] Reset the formatter branch tree to current main
 before opening review

Preserve the preparatory history without exposing a write-enabled workflow in the pull-request diff. The actual rustfmt change will be applied by the already-open PR event and self-clean before review.

+# TypeScript Nix interoperability verification
+
+The TypeScript client exposes strict, zero-runtime-dependency readers for the
+canonical Nix interoperability records published by `zed-interfaces`:
+
+```ts
+import {
+  parseNixAdapterRecord,
+  parseNixAdapterRecordJson,
+  canonicalNixAdapterRecordJson,
+  nixAdapterRecordSha256,
+  verifyCanonicalNixAdapterRecordJson,
+  verifyNixAdapterArtifactBytes,
+} from "@zed-pkg/client";
+```
+
+The supported schema is exactly:
+
+```text
+zed.nix-adapter/v1
+```
+
+Unknown directions, schema versions, fields, policy values, store-info JSON
+versions, and numeric values outside JavaScript's safe integer range fail
+closed.
+
+## Structural verification
+
+`parseNixAdapterRecord` validates and normalizes either direction:
+
+- `zed-to-nix`: immutable Zed artifact origin, explicit Nix intent, at least one
+  realized output, system/output agreement, and strict policy evidence;
+- `nix-to-zed`: immutable Nix selector and realization evidence, a translated
+  Zed artifact, strict policy evidence, and a closure-free selected output.
+
+The parser validates public package identity, exact SHA-256 and SHA-256 SRI
+syntax, Nix attributes, systems, outputs, store paths, signatures, references,
+artifact sizes, and supported store-info JSON versions. Runtime references in a
+version-1 Nix-to-Zed record are rejected rather than hidden in a wrapper.
+
+Input objects are never returned directly. The parser creates a fresh normalized
+object, sorts arrays whose order is non-semantic, removes default-empty optional
+arrays, and rejects duplicate references, signatures, or system/output pairs.
+Unknown fields cannot be used to smuggle credentials or private cache keys into
+the contract.
+
+## Canonical bytes and digest
+
+Rust emits compact JSON with all object keys recursively sorted. The TypeScript
+helper reproduces those bytes:
+
+```ts
+const canonical = canonicalNixAdapterRecordJson(untrustedValue);
+const digest = await nixAdapterRecordSha256(untrustedValue);
+```
+
+`verifyCanonicalNixAdapterRecordJson` additionally requires the supplied string
+to already be canonical; a trailing newline, pretty printing, different object
+key order, or omitted/default field drift is rejected. An optional expected
+lowercase SHA-256 can bind the exact adapter bytes.
+
+Digest helpers use the standard Web Crypto API available in browsers and Node
+22. They import no Node-only runtime module and add no package dependency.
+
+## Artifact-byte binding
+
+`verifyNixAdapterArtifactBytes` hashes exact Zed artifact bytes and checks both
+SHA-256 and byte size:
+
+- for `nix-to-zed`, it verifies the translated ordinary Zed artifact;
+- for `zed-to-nix`, it verifies the source Zed artifact recorded by the export.
+
+This catches archive tampering without requiring Nix or registry access.
+
+## What offline verification does not prove
+
+These helpers intentionally do **not**:
+
+- evaluate a flake or arbitrary Nix expression;
+- realize a derivation;
+- query a Nix store or binary cache;
+- verify that a diagnostic `/nix/store/...` path currently exists;
+- replay a derivation JSON digest, NAR hash, signature, or closure;
+- verify the contents of a tar/zip archive beyond its exact outer hash and size;
+- publish a Zed package, Nix overlay, or binary-cache object; or
+- grant trust to a cache signing key.
+
+Those claims require the pinned `zed` CLI, Nix/store commands, explicit trust
+policy, and the clean-room conformance workflows. The SDK distinguishes
+structural and byte-level verification from realization replay so callers do not
+mistake a well-formed provenance claim for proof that a build was reproduced.
+
+## Error safety
+
+Malformed JSON produces a generic syntax error. Unknown fields report their
+field name but never their value. Contract fields contain no token, password,
+private key, cache credential, or secret-delivery slot, so normalized records
+cannot serialize those values.

Add the canonical zed-interfaces dependency, materialize Zed packages under .vendor/.zed, and exclude generated dependency content from publication without fabricating a lockfile or nonexistent shared-library coordinate.

Add functional Elixir, Kotlin, Ruby, and PHP clients; explicit TypeScript entry points for Node.js, Deno, Bun, and edge runtimes; canonical Zed targets; and CI/drift checks that keep all fourteen maintained client slices aligned.

 The shared baseline is package/version lookup, text search, SHA-256-verified
 artifact download, organization claim, version yank/restore, and multipart
-publication using JSON `meta` plus raw `artifact` bytes. All ten clients
+publication using JSON `meta` plus raw `artifact` bytes. All fourteen clients
 implement that core lifecycle. Method names remain idiomatic to each language;
 for example, some clients additionally expose `restore` or `setYanked`
 conveniences over the same yank endpoint.
 
+TypeScript uses one npm-compatible package with explicit entry points for
+Node.js, Deno, Bun, and edge runtimes. See
+[`clients/README.md`](clients/README.md) for the canonical naming map, including
+`python` = Python 3, `go` = Golang, and `gleam` = Gleamlang.
+
 Every client transports bearer credentials but does not parse them. Registry
 redirects are refused. Artifact downloads do not carry the registry bearer
 because `download_url` may be a third-party presigned URL, and downloaded bytes
