From c3d7702c986eb5cda0d6a352644bce22f47c6c59 Mon Sep 17 00:00:00 2001 From: Randy Northrup Date: Mon, 28 Sep 2026 01:16:46 -0700 Subject: [PATCH 01/12] M69: web fetch on both backends, pinned to checked public addresses MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PLAN.md D49 (folds in M44b), built to the plan review's six rules. - web_fetch on the Model API backend (a new `network` tool class): HTTPS only; every DNS answer checked against the non-public ranges (loopback, private, link-local, CGNAT, metadata, reserved; IPv4 inside IPv6 judged as IPv4); the connection pinned to a checked address through Node's https, which VS Code patches for its proxy and certificates (the proxy is asked to tunnel to the address; only a TLS answer is read). Same-host redirects checked and pinned again (5 at most), another host's handed back; 5 MiB after decompression, 30 s, text types only; HTML to Markdown in one linear pass (entities 8.1.0 decodes references). - Asks per host in Manual, Edit automatically and Auto; Bypass runs it; Plan and Restricted Mode refuse it. The page reaches the model between random markers as untrusted content. No billing. - Muse Code: webFetch on the ide server, listed only in a trusted workspace without sandboxNetwork restricted, annotated open-world and not read-only, with the extension's own modal before every call. - Row: the URL, the size and type, and what the model read; 23 strings in fifteen languages; harness scenario web-fetch. - Tests over a fake resolver and transport, a loopback transport test, an integration test inside VS Code 1.139.1 and 1.125.0 with a loopback proxy; 28 red drills; live: public pages (no model) and one Muse Code turn (4 model attempts, contributor model). - Docs: README (Web fetch, permission modes, privacy), PRIVACY, SECURITY, AGENTS layout, CONTRIBUTING (Networks), CHANGELOG, PLAN (M69 status, D3, M44b, §9), docs/certification/m69.md.

IPv4 + outside IANA's special-purpose blocks and Azure's WireServer; IPv6 only + inside 2000::/3 and outside 2001::/23, 2001:db8::/32 and 3fff::/20; + IPv4-mapped, -compatible, NAT64 (64:ff9b::/96) and 6to4 judged by the + IPv4 inside; a zoned address is never public. + - `pageUrl.ts`: the first checks before any lookup or card: `https:`, no + credentials, 2,048 characters, not a local or reserved name (and not a + single label), not a non-public literal address. The WHATWG parser + normalises `0x7f.1`, `2130706433` and octal forms first. + - `webFetch.ts`: each hop resolves the name here and refuses it when any + answer is non-public, then pins the checked addresses (tried in the + resolver's order, never looked up again); same-host redirects are + checked and pinned again (at most five), another host's are handed back + as `moved`; 5 MiB after gzip/deflate/br decompression, 30 s, an + allow-list of text types, the charset from the header or HTML's + ``; the headers it reads are parsed with zod; the model's text is + a header line, the untrusted-content notice and the content between + markers with 8 random bytes. + - `htmlToMarkdown.ts`: one linear pass over the page; `entities` decodes + character references; scripts, styles, media, controls, SVG and hidden + parts are left out; inline depth, list/quote indents and table width are + capped. + - `fetchFailure.ts`: each refusal as the model reads it (English) and as + the row shows it (the display language). +- **The transport** (`src/host/web/pinnedRequest.ts`): Node's `https` to the + checked address, `servername` and `Host` carrying the name. VS Code patches + `https` in place for extensions, so the request takes the user's proxy and + certificates; its proxy agent tunnels to the address given. Only an answer + that came over TLS is read: a proxy's own refusal comes back on a plain + socket and is reported as `Proxy response (N) …`, which M56's network + failures read as a proxy refusal with their advice. +- **The Model API backend**: `web_fetch` (a new `network` tool class), + offered in a trusted workspace only; Bypass runs it, Plan refuses it, + Manual / Edit automatically / Auto ask per host with a `webFetch` card + naming the URL, "Always allow in this session" keyed on the host; refused + in Restricted Mode; a URL the fetch would refuse is refused before the + card. The instructions name the tool and say its content is untrusted. +- **Muse Code**: `webFetch` on the `ide` server (`src/host/ide/webFetchTool.ts`), + listed only while `isIdeWebFetchOffered` (trusted, `sandboxNetwork` not + `restricted`), with MCP annotations `readOnlyHint: false`, + `openWorldHint: true` (now passed through `tools/list`), and the + extension's own modal (`isWebFetchAllowed`: Allow once / Reject, naming + the host and the URL) before every call. +- **The row** (`toolPresentation.ts`, `ToolRow.tsx`): the URL beside the + label, "Fetched 48.2 kB (text/html)" under it (read from the result's + first line, `src/shared/webPage.ts`), and what the model read in the body. + The card reads "Muse wants to fetch ``". `formatBytes` in + `src/shared/l10n/text.ts`. +- **Strings**: 23 new keys in `en.ts` and the 14 UI tables (`check:l10n`: 0 + problems). +- **Dependency** (AGENTS rule 9, PLAN.md D3): `entities` 8.1.0, BSD-2-Clause, + no dependencies or peers, published 2026-09-07, already in the lockfile, + `npm audit --omit=dev`: 0 vulnerabilities. `THIRD_PARTY_NOTICES.txt` + regenerated. + +![The web-fetch harness scenario: a fetched page with its size line, a refused private address, and the per-host card](m69-web-fetch.png) + +## Research + +- **VS Code's fetch cannot pin.** `@vscode/proxy-agent`'s `createFetchPatch` + (read 2026-09-27) replaces any dispatcher the caller passes with its own + `undici.Agent` built from `allowH2` and the CA list only, whenever proxy + resolution or system certificates are on (the defaults); a `connect.lookup` + never reaches the connection. +- **VS Code's `https` can.** `createPatchedModules` merges the patch into + Node's `https` module object itself (`Object.assign(target, patch)`), so + `node:https` is the patched module. Its `PacProxyAgent` uses the global + agent for DIRECT (our `host`/`servername` options reach `tls.connect`) and + `HttpsProxyAgent` for a proxy, which sends `CONNECT :` and + upgrades with the caller's `servername`. + +## Tests + +| File | What it proves | +| ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `test/unit/publicAddress.test.ts` | Every non-public IPv4 block at both edges, the public neighbours, IPv6 inside and outside global unicast, embedded IPv4 forms, zones and names | +| `test/unit/pageUrl.test.ts` | `https:` only, credentials, length, reserved and single-label names, every spelling of a private literal, the per-host approval key | +| `test/unit/htmlToMarkdown.test.ts` | Headings, emphasis, links and images made absolute, lists, quotes, code fences, tables, what is left out, entities, broken markup, a hostile page stays linear | +| `test/unit/webFetch.test.ts` | The pipeline over a fake resolver and transport: pinning, every refusal, redirects (same host, rebinding, private, off HTTPS, another host, limit), bounds | +| `test/unit/pinnedRequest.test.ts` | The request options (address, `servername`, `Host`), a loopback request never resolving the name, abort, refusal, and an answer not over TLS refused | +| `test/unit/webFetcher.test.ts` | The window's fetch logs the host and outcome, never the path or query | +| `test/unit/ideWebFetch.test.ts` | The offer predicate, listing and annotations through `tools/list`, the modal before every call, declined and refused calls, the fetch's own refusal | +| `test/unit/webFetchConfirm.test.ts` | The modal names host and URL;

word web fetch as the reviewers found Every finding of the three class reviews of c3d7702c, in one pass: - Muse Code's Stop reaches the ide webFetch call: IdeMcpServer aborts a call's signal when its request closes unanswered or notifications/cancelled names its id (both captured from Muse Code 1.4.0); the modal is raced against it, the offer is checked again after the answer, the fetch gets the signal, one modal per URL at a time. - Checked addresses are raced as RFC 8305 says (250 ms attempt delay, first TLS connection wins, the others stopped). - Failures in web fetch's own words (host, addresses tried), not M56's Meta advice; a proxy's tunnel refusal recognised by the transport's code; the detail names error codes only, never a certificate's names. - Server text outside the markers only as short tokens; the final URL, the title and a moved target inside them. - The HTML converter is bounded (100,000 characters, prefix depth 4, body rows unpadded, title source capped). - Every trailing dot stripped, empty labels refused. - RFC 7050 NAT64 prefix discovery; answers under it judged by their IPv4. - Damaged compression is the coding's failure; charset only from , an unknown label ignored. - Model text says "this tool"; Model API rows localized for a moved page and Restricted Mode; side chats are not offered web fetch. - sandboxNetwork described in fifteen manifest tables; docs narrowed where they overclaimed; PAC/noProxy seeing the pinned address documented. - The integration proxy tests share one setup and judge only the page's tunnels (VS Code's own requests may use the window's proxy). The full local gate did not finish under machine load; the record says which parts passed (all of quality:gates, secrets, SAST, a11y for the changed scenario) and leaves the full run to CI.

NAT64 discovery asks the resolver the page's name used (getaddrinfo), and only its definite "no AAAA" (ENOTFOUND, or ENODATA) means no DNS64. A timeout, SERVFAIL or answers without an RFC 6052 prefix leave NAT64 unknown: no IPv6 answer is used, and a name or IPv6 literal with only IPv6 answers is refused as nat64Unknown (one new string, 14 tables). - A PermissionRequest hook's allow no longer replaces the per-host web fetch card; a hook may still deny or ask. Bypass and session-allowed hosts run without a card, as before. Muse Code's ide webFetch always asks in the extension's own modal and needed no change. - Swept the other failed-lookup and failed-check paths: none allows. Drills R32-R35 red and restored. Touched suites and the fast gates only (machine overloaded); the full gate is CI's.

Restricted Mode and a mode that now refuses refuse). - The fetch takes an isStillAllowed check, asked before each hop's lookup and connection, redirects included; a failed check ends it as "withdrawn" (one new string, 14 tables). - Once the page is in, it reaches the model only while fetch is still allowed. - Muse Code's ide webFetch passes its offer (trust, sandboxNetwork) as that check and asks it, with the stop, once the page is in. Swept every await on both paths. Drills R36-R43 red and restored. Touched suites and fast gates run; the full gate runs after this commit.
