Docs only; no code changed. Records: - the opt-in (default OFF) and the single user surface (web/index.html challenge-compat checkbox on the openTarget path only; the cold handleShare share-link path stays unarmed by design); - the trusted window -> SW -> kernel arm hop (ZP_OPEN_SHARE -> createTab -> transportFetch authoritative X-Zp-Challenge-Compat-Arm set/delete -> kernel birth-only read), with the fetchThroughRuntime inbound strip, so a proxied page can never self-arm; - the two-signal gate (trusted arm AND header/URL classification) at every relaxation point; - exactly what is projected: challenge-host CSP allowances (no wildcard, no egress), eval honored-not-manufactured, and the no-store skip for classified SUBRESOURCES only (the challenge document stays no-store); - the internal X-ZP-Challenge-Compat marker consumed/deleted at the SW so it never leaks to the page; - no-egress and no-forgery guarantees; - HONEST expectations: this is COMPATIBILITY (stops the proxy breaking the legitimate human challenge), NOT a solver/forger/bypass/clearance guarantee; real-zone clearance is server-authoritative and verified via a human-run live smoke (ZP_TURNSTILE_LIVE convention, NOT wired into CI), while CI validates only the mechanism against a local fixture (B6) that never contacts Cloudflare; - the constituent commits B1-B6.

This section records exactly what was +built, how to turn it on, the guarantees it does and does not make, and the +commits that built it.

So the mode is something the operator of a tab chooses at tab +creation, not a property a shared link can carry to a third party. + +### How the arm reaches the kernel (trusted hop only) + +The per-tab arm is a BIRTH-ONLY bit, set once when the tab is created and never +again. The trusted flow is: + +1. `web/index.html` `openTarget()` reads the checkbox and includes + `challengeCompat` in the `ZP_OPEN_SHARE` message to the service worker. +2. `web/sw.js` `createTab()` stores it as the per-tab `challengeCompat` arm bit + (birth-only; a live tab is never re-armed). +3. `web/sw.js` `transportFetch()` authoritatively manages the kernel request + header `X-Zp-Challenge-Compat-Arm`: it unconditionally DELETEs any inbound + (page-supplied) value, then SETs `1` only for an armed tab. This is the exact + pattern used for `X-ZP-Tab-Id` / `X-ZP-Runtime-Token`. +4. `cmd/wasm-kernel/main.go` `tabFor()` / `tabFromValues()` reads the arm at TAB + BIRTH ONLY. An already-born tab is returned as-is without touching + `ChallengeCompat`, so a forged inbound arm cannot self-arm a live tab. + +Defense in depth: `web/runtime-prelude.js` `fetchThroughRuntime()` also strips any +inbound `X-Zp-Challenge-Compat-Arm` before issuing a runtime fetch, mirroring the +service worker. The consequence is the load-bearing security property: a proxied +target page CANNOT arm itself. The arm exists only in the trusted +window -> service worker -> kernel hop. + +### The two-signal gate + +No relaxation ever happens on the arm alone. Every relaxation point requires BOTH: + +1. the trusted per-tab arm (above), AND +2. header/URL classification of the specific response as challenge traffic. + +Classification is `cmd/wasm-kernel/challenge.go` `targetIsChallengeDocument()`, a +pure predicate over response HEADERS and the FINAL URL only (it never reads or +sniffs the body): the response header `Cf-Mitigated: challenge`, OR host +`challenges.cloudflare.com`, OR path prefix `/cdn-cgi/challenge-platform/`. On the +default (unarmed) path the gate is always false and behavior is byte-identical to +today. + +### Exactly what is projected when both signals hold + +1. CSP challenge-host allowances (`web/zp-core.js` `fixedCSP({ challengeCompat })`). + When on, ZeroProxy ADDS only the literal host `https://challenges.cloudflare.com` + to `script-src`, `connect-src`, `frame-src`, and `child-src`. It adds NO + wildcard and NO direct-egress capability: target fetches still route through + the proxy transport. The document CSP is projected in `web/sw.js` `addCSP()`; + the script-response CSP in `scriptResponseHeaders()`. + +2. eval is HONORED, never MANUFACTURED. Challenge documents legitimately ship + `'unsafe-eval'`. ZeroProxy's challenge projection never adds `'unsafe-eval'`. + It rides only the pre-existing, target-authoritative `allowDynamicCompile` + grant (`X-ZP-Dynamic-Compile`), which is derived from the target's own CSP. If + the target did not grant eval, the projection does not invent it. + +3. no-store skip for SUBRESOURCES only (`internal/headers/policy.go` + `ConstructorPolicy(..., challengeCompat)`, gated by `cmd/wasm-kernel` + `challengeSubresourceSkip()`). ZeroProxy normally rewrites `Cache-Control` to + `no-store`. This overwrite is skipped ONLY for a classified challenge + SUBRESOURCE so Cloudflare's own cache/update semantics survive (e.g. + `turnstile/v0/api.js`). The skip carries a third, load-bearing term: the + challenge DOCUMENT (the navigation HTML, `isDoc == true`) STAYS on `no-store`. + The same computed boolean feeds both `ConstructorPolicy` passes so the second + pass cannot silently re-impose `no-store`. + +### Internal marker never leaks to the page + +The kernel emits an internal `X-ZP-Challenge-Compat` marker (only when both gate +signals hold, via `cmd/wasm-kernel/challenge.go` `applyChallengeCompat()`) to tell +the downstream service worker to project the challenge CSP. This marker is a +private signal between kernel and service worker; it is consumed and DELETEd in +`web/sw.js` (`addCSP()` and `scriptResponseHeaders()`) before the response reaches +the proxied page. It is distinct from the trusted arm header above. Neither header +ever reaches the target realm. + +### Guarantees + +- Default OFF. With the checkbox unchecked, no tab is armed, the gate is always + false, every projection is inert, and the response path is byte-identical to + the pre-Increment-1 behavior. The frozen membrane/policy invariants stay green. +- No egress escape. Challenge-compat adds host allowances to CSP but no wildcard + and no direct-fetch capability. All target traffic still routes through the + proxy transport; the no-egress invariant is preserved. +- No forgery, no synthesis. ZeroProxy does not read challenge bodies for + classification, does not interpret `_cf_chl_opt`, does not synthesize tokens, + and does not answer or replay the challenge. Classification is header/URL only. +- Honor-not-manufacture eval. `'unsafe-eval'` is only ever passed through from the + target's own grant, never added by challenge-compat. +- A page cannot self-arm. The arm is set exclusively in the trusted + window -> service worker -> kernel hop, deleted on every inbound page-controllable + path, and read birth-only by the kernel. + +### Honest expectations (the non-guarantee) + +This is COMPATIBILITY, not clearance. Enabling the mode stops ZeroProxy from +breaking the legitimate human-solved challenge. It does NOT guarantee the human +will be cleared, and it is NOT a solver, bypass, or token forger. Whether a real +Cloudflare zone issues clearance is server-authoritative: it depends on Cloudflare +risk signals, the human's interaction, cookies, client hints, and IP reputation, +none of which ZeroProxy controls or fabricates. + +Because real-zone clearance is server-authoritative, it cannot be asserted in CI. +What CI validates is the MECHANISM, not clearance: the Increment-1 end-to-end test +(`test/e2e/turnstile-compat.test.js`, B6) drives a real browser against a LOCAL +fixture that mimics a challenge (it emits `Cf-Mitigated: challenge` and a +`/cdn-cgi/challenge-platform/` subresource) and NEVER contacts Cloudflare. It +proves the armed path runs both relaxation points and that the OFF path is +unchanged. Real-zone clearance is left to a human-run live smoke test (the +`ZP_TURNSTILE_LIVE` convention name) that is deliberately NOT wired into CI and is +not part of any automated gate; it is run by a person against a live zone when +verification against the real service is desired. + +### Commits (Increment 1, B1-B6) + +| Step | Commit | Layer | What it added | +|---|---|---|---| +| B1 | `1142523` | `cmd/wasm-kernel` | Challenge classifier (`targetIsChallengeDocument`) + per-tab `ChallengeCompat` birth-only arm opt-in; arm read in `tabFor`/`tabFromValues`. | +| B2 | `b347062` | `internal/headers` | `ConstructorPolicy` skips the `no-store` overwrite for armed challenge SUBRESOURCES (`challengeSubresourceSkip`; document stays `no-store`). | +| B3 | `6081c90` | `web/zp-core.js` | `fixedCSP` projects the challenge host into script/connect/frame/child, honoring the target eval grant (never manufacturing eval). | +| B4 | `c8d9bd5` | `web/sw.js` | Threads the internal `X-ZP-Challenge-Compat` marker into CSP projection and plumbs the trusted `X-Zp-Challenge-Compat-Arm` set/delete; inbound strip in `runtime-prelude.js`. | +| B5 | `edae226` | `web/index.html` | Activates the mode: the opt-in checkbox and the trusted `ZP_OPEN_SHARE` arm sender (final activation of the dormant B1-B4 mechanism). | +| B6 | `e317379` | `test/e2e` | Armed-path challenge-compat trace harness against a local fixture (mechanism validation, no Cloudflare contact). | From 1585ce841c9f3744a483e0b9623772dcebe39f00 Mon Sep 17 00:00:00 2001 From: metaphorics <152830360+metaphorics@users.noreply.github.com> Date: Sun, 31 May 2026 07:22:26 +0900 Subject: [PATCH 025/100] refactor(server): decompose readSOCKS5Connect/handle/legacyZP under complexity budget Split the over-budget functions in cmd/zeroproxy-server into small, single-responsibility units while preserving every byte of observable behavior (SOCKS5 wire protocol, asset allowlist + default-deny, CSP bytes): - readSOCKS5Connect (cc 19, cog 20) -> socks5Negotiate (greeting + method select + auth) / socks5SelectMethod (pure method pick) / socks5ReadRequest (command + address + port) / readSOCKS5Port. Write-then-check-0xff ordering and method preference (0x02 > 0x00) preserved exactly. - handle (cc 16) path-routing switch -> an ordered route table dispatched top-to-bottom, mirroring the switch 1:1 with the same default-deny fallthrough. - legacyZP nested switch -> flat map lookups (control redirects + asset allowlist) with the same /__zp/error/ prefix branch and default-deny. - zeroCSP/serviceWorkerCSP -> single cspWithScriptSrc(r, scriptSrc) helper, removing the fragile strings.Replace. Both byte-pinned script-src literals survive as call-site arguments (static-policy.test.js stays green). Add routing_test.go: table-driven httptest coverage of handle's dispatch, the asset allowlist, and default-deny (the routing refactor previously had no test net).

Documented as deliberately distinct from HiddenHeader, which must not be merged in (it does not strip Location). - applyResponseDefaults: the fixed no-store/nosniff/CORS block, with the challengeCompat no-store skip. ConstructorPolicy is now a flat copy-loop + defaults call; golangci passes WITHOUT the nolint (cyclop/gocognit/nestif all satisfied). Behavior proven identical, not assumed: a transient differential harness compared the decomposed function against a frozen copy of the original over 4096 generated header sets x 8 flag combinations (32768 cases) -> 0 mismatches (harness run then deleted, not committed). A permanent characterization oracle (policy_oracle_test.go) pins the security-relevant header survival/strip set as regression coverage.

The cross-server ordering (count-limit before parse, byte-budget after canonicalize, dedupe last) is preserved verbatim as a documented security invariant. golangci passes WITHOUT the nolints. Behavior proven identical, not assumed: transient differential harnesses compared each decomposed function against a frozen copy of the original -> NormalizeRelayServers 221 inputs, NewWithRandAndServers 45 cases, 0 mismatches (harnesses run then deleted). A characterization oracle in shareurl_test.go pins the edge behavior as permanent regression coverage.

This is a pure mechanical extraction: the loop's control flow is unchanged (same branches, same order), and the body-close points and the cur=next ordering before redirectedRequest are preserved verbatim, so a rebuild-error still returns cur=next and a parse/scheme error still returns the old cur. Verified by difft (relocation only), golangci, the full zphttp suite incl. the redirectedRequest tests, and path-by-path analysis of every return. No generated differential harness: the TLS+HTTP transport behind RoundTrip cannot be cheaply faked, and a non-aliasing mechanical extraction is sound by inspection (unlike the htmltx aliasing case that needed one).

normalizeRelayServer: parse/validate/canonicalize one endpoint (scheme allow-list, credential/fragment rejection, userinfo+hash strip). - admitRelayServer: fold one raw candidate into the {out, seen, total} accumulator, enforcing the count cap (before blank-skip), the aggregate byte budget (charged before dedup), and first-seen append. - normalizeRelayServers: drive the input list. Behavior is byte-identical: proven by a transient old-vs-new differential (185 generated + edge cases across both allowLoopbackWS branches, every rejection path, caps, budget, dedup, coercion -> 0 mismatches; harness not committed). RED-before confirmed the gate genuinely fired on the monolith (cog 37 -> biome ci fail); green-after passes (exit 0). A new permanent characterization in core.test.js pins the contract the decomposition must preserve -- scheme/credential/fragment invariants, the count-cap-before- blank-skip order, and the aggregate-budget-charged-before-dedup semantics (the last two verified to fail under per-entry and charge-after-dedup mutations, so they genuinely discriminate).

The function takes a concrete *wsproto.Conn, so the frame source is injected as a func rather than mocking the relay -- internal DI, no production API added. Behavior-preserving: a transient differential lifted the original loop verbatim (only ReadFrame->readFrame, handlers->getHandlers() swapped) and drove it against runReadLoop over 11 branch/ordering cases (error truthy+falsy, close, text, binary, empty payloads, multi-frame ordering) -> 0 mismatches; harness deleted. RED-before confirmed the gate fired on the original (gocognit 24 -> golangci wasm fail); green-after is 0 issues. A permanent characterization (wsstream_test.go, the first runtime test of this previously //nolint'd membrane function) pins the contract: frame delivery by type, fail-closed stop on close/error, ordering, and that a read error stops the loop even with no handler installed.

Extract its post-fetch half (cookie capture, document transform, policy/challenge-compat header shaping, body-cancellation ownership, ResponseToJS marshal + resolve) into a free deliverResponse() that takes the already-fetched *http.Response, so it is drivable without the engine (no mock), plus three sub-helpers: transformDocumentResponse, applyResponsePolicy, installBodyCancellation. jsHTTP keeps only validate -> ensure -> RequestFromJS -> scheme -> engine.Do -> deliverResponse; releaseOnReturn := true, cancel, and the ownership defer stay byte-identical (deliverResponse RETURNS the resolved flag rather than mutating it across the boundary). //nolint removed. Load-bearing invariants preserved: challengeSub is computed once in applyResponsePolicy and RETURNED, so deliverResponse feeds the SAME value to ResponseToJS (no recompute); releaseOnReturn flips to false only once the body cancel goroutine owns teardown; every fail-closed resolve+return branch is intact. Behavior-preserving: a transient differential drove deliverResponse against the verbatim-lifted inline original over 8 branch cases (transform, body-nil, dynamic-compile on/off, redirect, cookies, armed challengeSub=true, credentials- omit), comparing the full observable tuple — resolved JS Response status+headers+ body, the returned releaseOnReturn, and cookie-jar state -> 0 mismatches; harness deleted. RED-before confirmed gocognit 42 fired on the original (golangci wasm); green-after is 0 issues. Permanent deliver_test.go pins the challenge-subresource cache-preservation security invariant (armed subresource keeps the target Cache-Control verbatim; non-armed and the challenge DOCUMENT both get no-store), releaseOnReturn per path, document transform, and cookie capture / credentials- omit. A recompute-challengeSub mutation is benign here (the classifier inputs are stable across ConstructorPolicy), so the once invariant is correctness rather than an observable divergence; the differential covers equivalence.

This drops fixedCSP's cognitive complexity from 19 (Biome max 15) under budget and removes the last noExcessiveCognitiveComplexity suppression in zp-core.js. The full CSP policy string stays assembled visibly in fixedCSP; only origin gathering moved, so the security-critical directive chain remains auditable in one place. Behavior-preserving, proven by a transient two-VM differential (HEAD vs working tree) over 220 cases -- challengeCompat x allowDynamicCompile x server-shapes x with/without location -- with 0 mismatches including throw-equivalence. The gate was proven red-before at the real path (cog 19 fires on the monolith; decomposed restored byte-identical via md5), not just green-after; nesting context makes a standalone probe under-count, so the real-path test is the only honest one. Adds a permanent connect-src confinement oracle (relay-origin gathering, dedup, no bare wildcard, exactly-one connect-src directive) -- every prior fixedCSP test used empty servers and never exercised buildConnectSrc's core.

So `document.cookie = "sid=attacker"` replaced a server's HttpOnly `sid` session cookie and stripped its HttpOnly protection: session fixation + HttpOnly bypass, a divergence from RFC 6265 §5.3 (real browsers reject a non-HTTP-API write that would overwrite an HttpOnly cookie). Thread the write source through: SetCookies (HTTP/Set-Cookie) stays trusted; SetDocumentCookie routes through setCookies(.., httpAPI=false). A non-HTTP write can neither create an HttpOnly cookie (forced off) nor overwrite an existing one (upsertLocked rejects the collision, keeps the old cookie). Adversarial test pins both directions plus that legitimate non-HttpOnly document writes still work; proven red-before (sid="attacker") -> green. The added guard branch pushed upsertLocked to cyclop 11, so its identity check and the duplicated negative-Max-Age delete test are extracted into sameCookieKey / isCookieDeletion -- reads better and clears the gate without a suppression.

ZeroProxy should avoid -creating contradictions caused by its own rewriting layer. It should not attempt -to forge a different browser identity. - -| Surface | Compatibility concern | -|---|---| -| `navigator.userAgent`, `userAgentData`, platform hints | Should match actual browser/client-hint behavior as much as the browser provides. | -| `navigator.cookieEnabled`, languages, online state | Should not contradict cookie/network behavior. | -| `screen`, `visualViewport`, device pixel ratio | Should remain internally consistent with layout results. | -| `performance.now`, navigation/resource timing | Should not be broken by proxy rewriting. | -| Canvas/WebGL/Audio APIs | Do not block ordinary reads needed by the page; broad anti-fingerprint spoofing is outside scope. | -| `crypto.getRandomValues`, `crypto.subtle` | Must work normally. | -| Storage APIs | Cookies are essential; local/session storage and IndexedDB should not fail unexpectedly if used by the page. | - -### Error and Retry Paths - -Cloudflare documents client-side error callbacks and retry behavior. ZeroProxy -should preserve: - -- `error-callback` invocation with an error code; -- automatic retry behavior unless widget options disable it; -- manual `turnstile.reset()` retry; -- timeout and expiry callback delivery; -- console warnings/exceptions when no callback handles the error. - -Documented error families and examples: - -| Code or family | Meaning | Retry expectation | -|---|---|---| -| `110100` | Invalid sitekey. | No. | -| `110110` | Sitekey not found. | No. | -| `110200` | Domain not authorized. | No. | -| `110600` | Challenge timed out. | Yes. | -| `110620` | Interaction timed out. | Yes. | -| `200100` | Clock or cache problem. | No. | -| `200500` | Iframe load error. | Yes. | -| `300*` | Generic challenge failure. | Yes. | -| `400020` | Invalid sitekey. | No. | -| `400070` | Sitekey disabled. | No. | -| `600*` | Generic challenge failure. | Yes. | - -The exact retry decision belongs to the Turnstile widget. ZeroProxy should avoid -turning a widget error into an unrelated proxy policy error; preserving the -callback path gives the embedding page a chance to recover. - -## Internal VM and Opcode Boundary - -The Managed Challenge runtime may use VM-like bytecode, generated code, -obfuscation, self-checks, and per-request opaque state. The observed page -supports that conclusion because it allows generated script execution, blob -workers/frames, strict challenge metadata, and versioned Cloudflare loaders. - -However, no stable opcode table is part of Cloudflare's public contract. Any -opcode mapping extracted from one request would be: - -- deployment-specific; -- request-bound; -- tied to opaque challenge state; -- subject to rotation; -- directly useful for challenge emulation and bypass. - -ZeroProxy documentation should therefore stop at the execution constraints and -browser compatibility surfaces listed above. It should not publish bytecode -disassembly, opcode semantics, interpreter pseudocode, token synthesis, or -automated challenge-answer procedures. - -## ZeroProxy Implementation Implications - -For legitimate manual compatibility, a Turnstile/Managed Challenge mode would -need to be explicit. The mode should preserve Cloudflare's public behavior while -keeping ZeroProxy's no-direct-egress invariant. - -Required behavior: - -1. Route `https://challenges.cloudflare.com/turnstile/v0/api.js` without - changing the application-visible URL or pinning a stale hashed implementation. -2. Route `/cdn-cgi/challenge-platform/...` same-zone challenge resources through - the target transport path. -3. Preserve challenge CSP semantics for scripts, frames, workers, `connect-src`, - and `blob:` where required. -4. Preserve Cloudflare cookies and client-hint negotiation across follow-up - challenge requests. -5. Preserve documented `window.turnstile` callbacks, hidden form input behavior, - reset, expiry, timeout, error, and remove paths. -6. Preserve user interaction event delivery for interactive challenges. -7. Fail closed when a challenge resource would otherwise escape ZeroProxy's - request classifier. - -Current ZeroProxy friction points to review before expecting challenge -compatibility: - -| ZeroProxy subsystem | Current behavior from repository docs | Turnstile/Challenge impact | -|---|---|---| -| Response CSP/header constructor | Target CSP and many policy headers are stripped and replaced with ZeroProxy CSP. | Managed Challenge pages rely on their CSP, COOP, COEP, CORP, and permissions policy. A compatibility mode would need a carefully scoped exception or equivalent policy projection. | -| Script rewriting | External, inline, worker, and dynamic scripts are laundered/re-written and parse failures fail closed. | Cloudflare challenge scripts are obfuscated, generated, and versioned. Rewriting can break semantics; a compatibility mode needs explicit treatment rather than generic source transformation. | -| Dynamic compilation | ZeroProxy wraps `Function`, `eval`, and string timers under a virtual scope. | Challenge documents explicitly allow `unsafe-eval`; wrapper fidelity and source-string masking can affect execution. | -| Blob workers | Blob/data worker scripts that cannot be synchronously rewritten may fail closed. | Observed challenge CSP allows `worker-src blob:`. Blocking blob workers can cause legitimate manual challenge failure. | -| Frames | Iframe/frame URLs are converted to encrypted `/zp/p` routes and clean realms are instrumented. | Challenge frames from `challenges.cloudflare.com` and `blob:` need compatible origin, postMessage, and policy behavior. | -| Network wrappers | Fetch/XHR/EventSource/sendBeacon are routed through `/zp/api/fetch`; semantics are prototype-level. | Turnstile error/retry paths are sensitive to network, redirect, CORS, cache, credentials, and timing differences. | -| Client hints and UA | Transport UA/client hints must remain internally consistent. | Cloudflare requests many client hints via `Accept-CH` and `Critical-CH`; contradictions can create compatibility failures. | -| Cookies | Go cookie jar owns target cookies and runtime mirrors non-HttpOnly cookies. | Challenge clearance and retry state depend on path/domain/secure/HttpOnly semantics being preserved across requests. | - -Repository code touchpoints: - -| File | Review focus for Turnstile/Challenge compatibility | -|---|---| -| `web/zp-core.js` | `fixedCSP()` currently defines proxy document CSP.

A page with an embedded Turnstile widget loads the exact documented - `api.js` URL. -2. The request is carried through ZeroProxy's controlled transport path. -3. The widget renders inside the target page without direct browser egress. -4. `callback`, `error-callback`, `expired-callback`, and `timeout-callback` - execute in the expected page realm. -5. `cf-turnstile-response` is added to a form and submitted through the normal - target page flow. -6. `turnstile.reset`, `turnstile.getResponse`, and `turnstile.remove` behave - according to Cloudflare's public API. -7. A Managed Challenge page can load its same-zone orchestrator, allowed - Cloudflare resources, permitted frames, permitted workers, and allowed - network endpoints without escaping the classifier. -8. Challenge cookies and client hints remain consistent across reload/retry. -9. Failure paths surface as Turnstile or Cloudflare challenge errors, not as - ZeroProxy policy leaks or direct native fetches. - -These checks validate browser compatibility. They do not validate CAPTCHA -solving or Cloudflare bypass. - -## Implemented: Increment 1 (challenge compatibility mode) - -The compatibility surface described above is partially shipped as an opt-in, -default-OFF "challenge compatibility mode". This section records exactly what was -built, how to turn it on, the guarantees it does and does not make, and the -commits that built it. It is COMPATIBILITY only: it stops ZeroProxy from breaking -a legitimate human's Cloudflare challenge. It is NOT a solver, forger, bypass, or -clearance guarantee. The non-goals at the end of "ZeroProxy Implementation -Implications" remain in force. - -### What it is, in one sentence - -When a real human opts in, and only then, ZeroProxy stops imposing four of its -own hardening defaults on responses it classifies (by header/URL only) as -Cloudflare challenge traffic, so the human's browser can run the challenge it was -already going to run. Nothing about the challenge is interpreted, answered, or -replayed. - -### How to enable it (default OFF) - -The mode is off unless the user explicitly turns it on. There is exactly one user -surface: the "Challenge compatibility mode (Cloudflare Turnstile)" checkbox on the -proxy entry form (`web/index.html`, id `challenge-compat`). The opt-in is read in -`openTarget()` and travels only on the trusted `ZP_OPEN_SHARE` window-to-service- -worker message. - -Scope limit, stated honestly: arming is available ONLY on the entry-form -(`openTarget`) path. The cold share-link recipient path (`handleShare`, for -someone opening a shared `/zp/...` link directly) has no checkbox and stays -unarmed by design. So the mode is something the operator of a tab chooses at tab -creation, not a property a shared link can carry to a third party. - -### How the arm reaches the kernel (trusted hop only) - -The per-tab arm is a BIRTH-ONLY bit, set once when the tab is created and never -again. The trusted flow is: - -1. `web/index.html` `openTarget()` reads the checkbox and includes - `challengeCompat` in the `ZP_OPEN_SHARE` message to the service worker. -2. `web/sw.js` `createTab()` stores it as the per-tab `challengeCompat` arm bit - (birth-only; a live tab is never re-armed). -3. `web/sw.js` `transportFetch()` authoritatively manages the kernel request - header `X-Zp-Challenge-Compat-Arm`: it unconditionally DELETEs any inbound - (page-supplied) value, then SETs `1` only for an armed tab. This is the exact - pattern used for `X-ZP-Tab-Id` / `X-ZP-Runtime-Token`. -4. `cmd/wasm-kernel/main.go` `tabFor()` / `tabFromValues()` reads the arm at TAB - BIRTH ONLY. An already-born tab is returned as-is without touching - `ChallengeCompat`, so a forged inbound arm cannot self-arm a live tab. - -Defense in depth: `web/runtime-prelude.js` `fetchThroughRuntime()` also strips any -inbound `X-Zp-Challenge-Compat-Arm` before issuing a runtime fetch, mirroring the -service worker. The consequence is the load-bearing security property: a proxied -target page CANNOT arm itself. The arm exists only in the trusted -window -> service worker -> kernel hop. - -### The two-signal gate - -No relaxation ever happens on the arm alone. Every relaxation point requires BOTH: - -1. the trusted per-tab arm (above), AND -2. header/URL classification of the specific response as challenge traffic. - -Classification is `cmd/wasm-kernel/challenge.go` `targetIsChallengeDocument()`, a -pure predicate over response HEADERS and the FINAL URL only (it never reads or -sniffs the body): the response header `Cf-Mitigated: challenge`, OR host -`challenges.cloudflare.com`, OR path prefix `/cdn-cgi/challenge-platform/`. On the -default (unarmed) path the gate is always false and behavior is byte-identical to -today. - -### Exactly what is projected when both signals hold - -1. CSP challenge-host allowances (`web/zp-core.js` `fixedCSP({ challengeCompat })`). - When on, ZeroProxy ADDS only the literal host `https://challenges.cloudflare.com` - to `script-src`, `connect-src`, `frame-src`, and `child-src`. It adds NO - wildcard and NO direct-egress capability: target fetches still route through - the proxy transport. The document CSP is projected in `web/sw.js` `addCSP()`; - the script-response CSP in `scriptResponseHeaders()`. - -2. eval is HONORED, never MANUFACTURED. Challenge documents legitimately ship - `'unsafe-eval'`. ZeroProxy's challenge projection never adds `'unsafe-eval'`. - It rides only the pre-existing, target-authoritative `allowDynamicCompile` - grant (`X-ZP-Dynamic-Compile`), which is derived from the target's own CSP. If - the target did not grant eval, the projection does not invent it. - -3. no-store skip for SUBRESOURCES only (`internal/headers/policy.go` - `ConstructorPolicy(..., challengeCompat)`, gated by `cmd/wasm-kernel` - `challengeSubresourceSkip()`). ZeroProxy normally rewrites `Cache-Control` to - `no-store`. This overwrite is skipped ONLY for a classified challenge - SUBRESOURCE so Cloudflare's own cache/update semantics survive (e.g. - `turnstile/v0/api.js`). The skip carries a third, load-bearing term: the - challenge DOCUMENT (the navigation HTML, `isDoc == true`) STAYS on `no-store`. - The same computed boolean feeds both `ConstructorPolicy` passes so the second - pass cannot silently re-impose `no-store`. - -### Internal marker never leaks to the page - -The kernel emits an internal `X-ZP-Challenge-Compat` marker (only when both gate -signals hold, via `cmd/wasm-kernel/challenge.go` `applyChallengeCompat()`) to tell -the downstream service worker to project the challenge CSP. This marker is a -private signal between kernel and service worker; it is consumed and DELETEd in -`web/sw.js` (`addCSP()` and `scriptResponseHeaders()`) before the response reaches -the proxied page. It is distinct from the trusted arm header above. Neither header -ever reaches the target realm. - -### Guarantees - -- Default OFF. With the checkbox unchecked, no tab is armed, the gate is always - false, every projection is inert, and the response path is byte-identical to - the pre-Increment-1 behavior. The frozen membrane/policy invariants stay green. -- No egress escape. Challenge-compat adds host allowances to CSP but no wildcard - and no direct-fetch capability. All target traffic still routes through the - proxy transport; the no-egress invariant is preserved. -- No forgery, no synthesis. ZeroProxy does not read challenge bodies for - classification, does not interpret `_cf_chl_opt`, does not synthesize tokens, - and does not answer or replay the challenge. Classification is header/URL only. -- Honor-not-manufacture eval. `'unsafe-eval'` is only ever passed through from the - target's own grant, never added by challenge-compat. -- A page cannot self-arm. The arm is set exclusively in the trusted - window -> service worker -> kernel hop, deleted on every inbound page-controllable - path, and read birth-only by the kernel. - -### Honest expectations (the non-guarantee) - -This is COMPATIBILITY, not clearance. Enabling the mode stops ZeroProxy from -breaking the legitimate human-solved challenge. It does NOT guarantee the human -will be cleared, and it is NOT a solver, bypass, or token forger. Whether a real -Cloudflare zone issues clearance is server-authoritative: it depends on Cloudflare -risk signals, the human's interaction, cookies, client hints, and IP reputation, -none of which ZeroProxy controls or fabricates. - -Because real-zone clearance is server-authoritative, it cannot be asserted in CI. -What CI validates is the MECHANISM, not clearance: the Increment-1 end-to-end test -(`test/e2e/turnstile-compat.test.js`, B6) drives a real browser against a LOCAL -fixture that mimics a challenge (it emits `Cf-Mitigated: challenge` and a -`/cdn-cgi/challenge-platform/` subresource) and NEVER contacts Cloudflare. It -proves the armed path runs both relaxation points and that the OFF path is -unchanged. Real-zone clearance is left to a human-run live harness, -`scripts/turnstile-live.mjs` (`npm run turnstile:live`), deliberately NOT wired into -CI and not part of any automated gate. It boots the real stack, opens an -instrumented browser at the proxy UI, and prints a REDACTED trace + verdict (the -projected CSP, the internal-marker strip, and an egress-escape count) while a person -solves a real challenge through the proxy. It records no tokens, cookie values, -request bodies, or raw URLs, and asserts no clearance (server-authoritative) — it -surfaces only whether the membrane BREAKS the legitimate flow. Its egress check -observes top-level + popup page requests; cross-origin challenge iframes (OOPIF) and -service-worker-internal traffic are not fully captured, so the browser's own devtools -Network tab is the authoritative cross-check. - -### Known limitations (Increment 1) - -These are documented compatibility gaps, not security gaps. Each is bounded by the -two-signal gate (the tab must be armed) and stays inside the bounded projection. - -- **The service-worker script path classifies on the request URL only.** The kernel - DOCUMENT path (`cmd/wasm-kernel/challenge.go`) classifies on the `cf-mitigated` - header OR the final URL. The service-worker SCRIPT path (`web/sw.js` - `rewriteScriptResponse` / `isChallengeURL`) classifies on the request target - URL's host/path ONLY — it deliberately reads no response header and does not - resolve a follow-redirect final URL. Two bounded mis-classifications follow, both - requiring the arm bit: - - *Under-classify*: a header-only challenge script, or a script request that - redirects TO a challenge URL, receives the restrictive default CSP and the - challenge subresource may fail to execute. Fail-safe; nothing is weakened. - - *Over-classify*: a challenge-looking request URL (`challenges.cloudflare.com` - or `/cdn-cgi/challenge-platform/`) that redirects AWAY to a non-challenge - script receives the challenge projection. That projection adds ONLY the fixed - `challenges.cloudflare.com` host to script/connect/frame/child-src, with - `'unsafe-eval'` present only if the target's own CSP already granted it (never - manufactured). It cannot widen egress or admit an arbitrary origin. - - Closing this gap (consulting the header / final URL on the script path) is - deferred to a future increment driven by live measurement: re-deriving the - classification on the membrane script path without a live signal would add - membrane complexity for an edge that real Cloudflare challenges — served from the - challenge host/path — do not currently exercise. - -### Commits (Increment 1, B1-B6) - -| Step | Commit | Layer | What it added | -|---|---|---|---| -| B1 | `1142523` | `cmd/wasm-kernel` | Challenge classifier (`targetIsChallengeDocument`) + per-tab `ChallengeCompat` birth-only arm opt-in; arm read in `tabFor`/`tabFromValues`. | -| B2 | `b347062` | `internal/headers` | `ConstructorPolicy` skips the `no-store` overwrite for armed challenge SUBRESOURCES (`challengeSubresourceSkip`; document stays `no-store`). | -| B3 | `6081c90` | `web/zp-core.js` | `fixedCSP` projects the challenge host into script/connect/frame/child, honoring the target eval grant (never manufacturing eval). | -| B4 | `c8d9bd5` | `web/sw.js` | Threads the internal `X-ZP-Challenge-Compat` marker into CSP projection and plumbs the trusted `X-Zp-Challenge-Compat-Arm` set/delete; inbound strip in `runtime-prelude.js`. | -| B5 | `edae226` | `web/index.html` | Activates the mode: the opt-in checkbox and the trusted `ZP_OPEN_SHARE` arm sender (final activation of the dormant B1-B4 mechanism). | -| B6 | `e317379` | `test/e2e` | Armed-path challenge-compat trace harness against a local fixture (mechanism validation, no Cloudflare contact). | diff --git a/internal/headers/policy.go b/internal/headers/policy.go index 848edd6..67b4876 100644 --- a/internal/headers/policy.go +++ b/internal/headers/policy.go @@ -18,16 +18,7 @@ var hidden = map[string]struct{}{ // strips target policy/storage/network-control headers and applies ZeroProxy's // no-store default.

This is a correctness bug, not only a compatibility bug. - -Affected code: - -- `web/js-rewriter.js`: scope collection treats block body declarations too uniformly and does not model `var` hoisting to the nearest function/program scope. - -Required Phase 3 behavior: - -- Implement a real scope model: - - program scope; - - function scope; - - block scope; - - catch scope; - - class scope where relevant; - - module import/export bindings; - - `var` and function-declaration hoisting to function/program scope; - - `let`/`const`/class bindings to block scope; - - parameter and function-name scopes. -- Add rewriter unit tests for shadowing across blocks, functions, loops, catch clauses, destructuring, imports, class names, and nested functions. -- Fail closed only for unsupported syntax or ambiguous transformations, not for valid local-shadowing code. - -### 8. Inline classic and event-handler fallback is not strict fail-closed - -Current behavior: - -- External script rewrite failure returns a throwing script. -- Inline module fallback returns a throwing script. -- Inline classic script and event-handler fallback can execute original source wrapped in `__zp_runClassic` / `__zp_runEvent` when the OXC rewriter is unavailable. - -Affected code: - -- `internal/htmltx/transform.go`: `rewriteInlineScript()` and `rewriteEventHandler()` compatibility fallback. -- `cmd/wasm-kernel/main.go`: `rewriteScript()` returns false when the JS rewriter is unavailable or fails. - -Required Phase 3 behavior: - -- Default strict path: inline classic scripts and event handlers must block when OXC rewrite fails. -- If a compatibility mode is retained, it must be explicit, test-named, and documented as lower assurance. -- The default E2E path must prove parse/rewrite failures do not execute original inline source. - -### 9. Compatibility passthrough allowlist remains an acceptance-boundary exception - -Current behavior: - -- `/__zp/api/script` bypasses rewriting for selected third-party challenge/tag-manager hosts. -- This is not a parse-failure fallback, but it is still a strict-mode exception. - -Affected code: - -- `web/sw.js`: `shouldPassthroughScript()`. - -Required Phase 3 behavior: - -- Decide one strict default: - - remove passthrough from strict mode; or - - move passthrough behind an explicit compatibility policy flag with host/path allowlist tests. -- Strict/high-assurance acceptance must not depend on passthrough scripts executing unrewritten. - -### 10. Worker script API compatibility remains partial - -Current behavior: - -- Worker `fetch` and `importScripts` are routed. -- Worker XHR, WebSocket, EventSource, WebRTC/WebTransport, device APIs, and blob/data worker scripts are blocked or prototype-level. - -Required Phase 3 behavior: - -- Keep blocked APIs explicit and test-covered. -- Add compatibility only where it can preserve the transport boundary: - - worker XHR over `${controlPrefix}/api/fetch` if needed; - - worker EventSource over fetch stream if needed; - - worker WebSocket only through the existing `ZP_WS_OPEN`/`__zp_stream` path with per-tab capability. -- Do not silently expose native worker networking. - -### 11. ZeroProxy control artifacts are script-observable through DOM fingerprinting APIs - -Observed behavior: - -ZeroProxy must attach internal attributes and injected boot assets to maintain routing and rewriting state, for example `data-zp-target-url`, `data-zp-blocked-url`, `data-zp-integrity`, `data-zp-blocked-script`, `#__zp-boot`, and injected control-prefix assets such as `/zp/assets/zp-core.js` / `/zp/assets/runtime-prelude.js` after the Gate 1 cutover. Anti-bot and integrity scripts can enumerate these artifacts through: - -- `element.innerHTML` and `element.outerHTML`; -- `getAttribute`, `hasAttribute`, `getAttributeNames`, and `attributes` / `NamedNodeMap`; -- `document.scripts`, `getElementsByTagName('*')`, `getElementsByTagName('script')`, and related count APIs; -- `NodeIterator`, `TreeWalker`, and manual traversal; -- selector APIs such as `querySelectorAll('[data-zp-target-url]')`, `matches()`, and `closest()`. - -Required Phase 3 behavior: - -- Add a stealth membrane that hides ZeroProxy framework artifacts from target-page script-level inspection while preserving internal access through captured native references and private state such as `WeakMap` metadata. -- The membrane must cover at least: - - `Element.prototype.innerHTML` and `outerHTML` getters; - - `Element.prototype.getAttribute`, `hasAttribute`, `getAttributeNames`, `attributes`; - - `NamedNodeMap.length`, numeric indexing, `item()`, `getNamedItem()`, iteration, and property access; - - `Document.prototype.getElementsByTagName` and `Element.prototype.getElementsByTagName` for `*`, `script`, `meta`, `link`, and any tag that can expose injected assets; - - `Document.prototype.scripts` and any available script collection getters; - - `Document.prototype.createNodeIterator` and `createTreeWalker`; - - selector APIs that directly query `data-zp-*` attributes or injected ZeroProxy script IDs/sources. -- The membrane must not hide target-authored attributes that merely contain the substring `zp`; it hides the exact ZeroProxy-reserved namespace `data-zp-*` and exact internal boot assets. -- The membrane must preserve web-compatible collection behavior: stable order, numeric indexing, `length`, `item()`, iteration, and function `this` binding. -- Masked methods must be integrated with the existing native-function stringification layer so `Function.prototype.toString` does not expose wrapper bodies. -- Tests must assert both invisibility to page scripts and continued internal functionality. - -Reference implementation shape for the core membrane: - -```js -(() => { - const mask = (fn, name) => { if (typeof fn === 'function') maskNativeFunction(fn, name); }; - const isZPAttr = name => typeof name === 'string' && name.toLowerCase().startsWith('data-zp-'); - const isZPAsset = node => node && ( - node.id === '__zp-boot' || - (node.localName === 'script' && isZeroProxyAssetURL(Native.getAttribute.call(node, 'src'))) - ); - - const origInnerHTMLGet = Object.getOwnPropertyDescriptor(Element.prototype, 'innerHTML').get; - const origOuterHTMLGet = Object.getOwnPropertyDescriptor(Element.prototype, 'outerHTML').get; - const origGetAttribute = Element.prototype.getAttribute; - const origHasAttribute = Element.prototype.hasAttribute; - const origGetAttributeNames = Element.prototype.getAttributeNames; - const origAttributesGet = Object.getOwnPropertyDescriptor(Element.prototype, 'attributes').get; - - Object.defineProperty(Element.prototype, 'innerHTML', { - get() { return sanitizeSerializedHTML(origInnerHTMLGet.call(this)); }, - configurable: true, - enumerable: true - }); - - Object.defineProperty(Element.prototype, 'outerHTML', { - get() { return sanitizeSerializedHTML(origOuterHTMLGet.call(this)); }, - configurable: true, - enumerable: true - }); - - Element.prototype.getAttribute = function(name) { - if (isZPAttr(name)) return null; - return origGetAttribute.apply(this, arguments); - }; - mask(Element.prototype.getAttribute, 'getAttribute'); - - Element.prototype.hasAttribute = function(name) { - if (isZPAttr(name)) return false; - return origHasAttribute.apply(this, arguments); - }; - mask(Element.prototype.hasAttribute, 'hasAttribute'); - - Element.prototype.getAttributeNames = function() { - return origGetAttributeNames.apply(this, arguments).filter(n => !isZPAttr(n)); - }; - mask(Element.prototype.getAttributeNames, 'getAttributeNames'); - - Object.defineProperty(Element.prototype, 'attributes', { - get() { return filteredNamedNodeMap(origAttributesGet.call(this), attr => !isZPAttr(attr.name)); }, - configurable: true, - enumerable: true - }); - - const filterNodeList = list => filteredLiveCollection(list, node => !isZPAsset(node)); - - const origDocumentGetElementsByTagName = Document.prototype.getElementsByTagName; - const origElementGetElementsByTagName = Element.prototype.getElementsByTagName; - Document.prototype.getElementsByTagName = function(tag) { - const raw = origDocumentGetElementsByTagName.apply(this, arguments); - return shouldFilterTag(tag) ?

They must use captured native descriptors and avoid avoidable string allocation except at API boundaries that are defined to return strings. - -### 12. `WebSocketStream` is blocked instead of mapped onto the proxied WebSocket path - -Current behavior: - -- `web/runtime-prelude.js` blocks `WebSocketStream` with other unsupported networking APIs. -- Some modern browser/anti-bot code checks for `WebSocketStream` or uses the Streams API shape directly. - -Required Phase 3 behavior: - -- Provide a `WebSocketStream` polyfill when native `WebSocketStream` is absent or blocked by ZeroProxy policy. -- The polyfill must use the existing ZeroProxy `WebSocket` constructor/membrane so traffic still routes through `ZP_WS_OPEN` / `__zp_stream` and never through native networking. -- Constructor semantics: - - `new WebSocketStream(url, options = {})` resolves `url` against the virtual location/base URL; - - `options.protocols` is passed to `WebSocket` without inventing unsupported options; - - `opened` is a promise resolving to `{ readable, writable, protocol, extensions }` after WebSocket open; - - `closed` is a promise resolving to `{ closeCode, reason }` after close; - - `readable` enqueues WebSocket messages and closes on socket close; - - `writable.write(chunk)` sends chunks through `ws.send(chunk)`, `close()` closes the socket, and `abort()` closes the socket; - - errors reject `opened` when open has not completed and error/close streams after open as web-compatibly as practical. -- The constructor and methods must be masked through the existing native-stringification layer. - -Reference implementation shape: - -```js -if (!root.WebSocketStream) { - class WebSocketStream { - constructor(url, options = {}) { - const virtualBase = root.__zp_virtualLocation?.href || location.href; - const targetUrl = new URL(url, virtualBase).href; - let socketClosedResolve; - this.closed = new Promise(resolve => { socketClosedResolve = resolve; }); - this.opened = new Promise((resolve, reject) => { - try { - const ws = new root.WebSocket(targetUrl, options.protocols); - ws.binaryType = 'arraybuffer'; - let controllerReadable; - const readable = new ReadableStream({ - start(controller) { controllerReadable = controller; }, - cancel() { ws.close(); } - }); - const writable = new WritableStream({ - write(chunk) { ws.send(chunk); }, - close() { ws.close(); }, - abort() { ws.close(); } - }); - ws.onopen = () => resolve({ readable, writable, protocol: ws.protocol, extensions: ws.extensions || '' }); - ws.onmessage = event => { if (controllerReadable) controllerReadable.enqueue(event.data); }; - ws.onerror = err => reject(err); - ws.onclose = event => { - try { controllerReadable && controllerReadable.close(); } catch {} - socketClosedResolve({ closeCode: event.code, reason: event.reason }); - }; - } catch (err) { - reject(err); - } - }); - } - } - maskNativeFunction(WebSocketStream, 'WebSocketStream'); - root.WebSocketStream = WebSocketStream; -} -``` - -## Phase 3 integration guidelines - -- Treat the route-prefix cutover as a fail-closed scoping change: narrow Service Worker scope only after every shell, document, API, asset, error, and optional relay route lives under the same prefix. -- Treat `server` fragment parameters as control-plane state. They are parsed only by the shell, stored in Service Worker tab/entry context, inherited downward, and never accepted from target-authored document URLs or request parameters. -- Treat the `` / document-navigation rewrite bug as a kernel correctness fix, not a compatibility enhancement. It must land before any E2E fixture relies on target-page navigation. -- Treat dynamic HTML regex removal as a clean cutover for markup transformation. Do not keep a second regex fallback path for malformed HTML; browser parser behavior is the contract. -- Treat the stealth membrane as a consistency layer over ZeroProxy-owned artifacts. Internal code must use captured native APIs or private metadata; page code must see target-authored DOM, not ZeroProxy implementation details. -- Treat `WebSocketStream` as an API facade over the existing proxied `WebSocket` path. Do not add a parallel transport. -- Every new membrane hook must include a test proving both directions: page-observable hiding works, and ZeroProxy internal behavior still works. -- Implementation must avoid redundant string serialization and repeated full-collection materialization where a live-filtered proxy or indexed lazy scan is sufficient. - -## Implementation sequence - -### Gate 0: Add failing fixtures first - -Add tests before changing behavior: - -- Route namespace and relay inheritance tests: - - shell served from `controlPrefix` registers the Service Worker with `scope: controlPrefix`; - - `/p/...`, `/__zp/...`, and root-scoped controlled URLs are absent from newly generated URLs after the cutover; - - unknown same-origin navigation inside `controlPrefix` fails closed; - - unknown same-origin paths outside `controlPrefix` cannot serve target content or runtime APIs; - - `#k=&server=...` parsing validates, normalizes, de-duplicates, bounds, stores, and erases relay server fragments; - - child navigations, iframes, workers, runtime API calls, WebSocket, and `WebSocketStream` inherit the selected server list. -- Go HTML-transform tests: - - ``, ``, `
