fix(ci): decompress release manifest download

A no-op re-publish produced new manifest bytes and checksum for
identical content, which raced the CDN cache and failed verification.
Compare against the existing manifest verbatim and keep its updated_at
when the merged result is unchanged.

+# Yakit Browser Agent Architecture
+
+## Goals
+
+- Reuse a user's real, authenticated browser session without exporting a complete browser profile.
+- Let an AI agent inspect a deliberately shared tab and request human takeover for QR codes, MFA, CAPTCHA, or device confirmation.
+- Keep proxy, Cookie, User-Agent, page-context, page-function, recording, Chromium debugger and browser transform capabilities behind one typed command boundary.
+- Make grants short lived, tab scoped, visible, and revocable.
+
+## Layers
+
+### Capability layer
+
+The background service owns browser capabilities. Every remote command passes through one router before it reaches browser APIs.
+
+| Method | Required scope | Effect |
+| --- | --- | --- |
+| `browser.tabs` | `browser.tabs.read` | Lists only tabs included in the active grant |
+| `browser.frames` | `browser.tabs.read` | Lists main, same-origin, and cross-origin frames for a granted tab |
+| `browser.context` | `browser.dom.read` | Captures a bounded structured snapshot and diff; Storage and Cookie require their own scopes |
+| `browser.node.inspect` | `browser.dom.read` | Inspects a document-bound node without returning the current input value |
+| `browser.node.action` | `browser.dom.write` | Clicks, focuses, scrolls, or writes a value through a current node reference |
+| `browser.cookies` | `browser.cookies.read` | Reads cookies for a granted tab |
+| `browser.takeover` | `browser.tab.activate` | Focuses a granted tab for a human step |
+| `browser.handoff.request` | `browser.human.takeover` | Starts a visible QR/MFA/CAPTCHA/device-confirmation handoff |
+| `browser.handoff.status` | `browser.human.takeover` | Reads the current task's handoff state |
+| `browser.network.status/list` | `browser.network.read` | Reads capture state and request metadata |
+| `browser.network.start/stop/clear` | `browser.network.capture` | Controls a bounded capture session for a granted document |
+| `browser.network.export` | `browser.network.sensitive.read` | Builds a replay packet from explicitly captured headers/body |
+| `browser.invoke` | `browser.page.invoke` | Calls an existing page-world function by path |
+| `browser.eval` expression | `browser.page.eval.expression` | Executes one parenthesized expression in a granted page world |
+| `browser.eval` program | `browser.page.eval.program` | Executes statements and side effects under an independent high-risk scope |
+| `browser.recording.status/get` | `browser.recording.read` | Reads bounded business Traces, Pipeline events and value links for a granted document |
+| `browser.recording.start/stop/clear` | `browser.recording.control` | Controls the document-bound MAIN-world recorder |
+| recording value previews | `browser.recording.sensitive.read` | Includes bounded short-lived input/output previews; off by default |
+| `browser.callable.list` | `browser.recording.read` | Lists callable metadata retained by the current granted document |
+| `browser.callable.create/execute/delete` | `browser.callable.execute` | Creates or invokes a recorded call or captured business closure without exporting keys; deep-capture creation also requires debugger control |
+| `browser.deep_capture.status` | `browser.debugger.read` | Reads bounded pause state, frames and scopes |
+| `browser.deep_capture.start/keepalive/resume/detach` | `browser.debugger.control` | Controls a one-shot Chromium function/request breakpoint and its pause lifecycle |
+| `browser.transform.profile.list` | `browser.transform.read` | Lists document-bound plaintext/wire transform profiles visible to the active grant |
+| `browser.transform.profile.save/delete` | `browser.transform.manage` | Creates, updates or removes a validated transform pipeline for a granted document |
+| `browser.transform.execute` | `browser.transform.execute` | Runs one request or response through the selected live-page function pipeline |
+| `proxy.list` | `browser.proxy.read` | Lists extension proxy profiles |
+| `proxy.switch` | `browser.proxy.write` | Switches the browser proxy profile |
+
+The transport never calls browser APIs directly.
+
+### Grant layer
+
+A grant contains:
+
+- an unpredictable session ID;
+- a task ID;
+- one or more explicit tab, frame, and document IDs with their origin and grant-time URL;
+- an explicit set of capability scopes;
+- creation and expiration timestamps.
+
+Expired grants are rejected and removed. Reloading or navigating a document returns `stale_document`; navigation to a different origin returns `origin_changed`. Neither condition silently retargets an operation. The UI still offers read/control presets, but those presets only create concrete scope sets and are not stored as authorization levels. A remote caller cannot expand a grant. Only extension UI initiated by the user can create or replace one.
+
+### Transport layer
+
+Bridge v3 supports authenticated loopback WebSocket and optional Native Messaging:
+
+```text
+Browser extension -> ws://127.0.0.1:<port>/extension -> Yak engine / AI session
+```
+
+The Yak gRPC process owns this listener and starts it on `127.0.0.1:64333` by default. Yakit controls it through the existing `RequestYakURL` RPC with the `browser-extension://` schema, so pairing, approval, device rename and revocation do not add dedicated gRPC methods.
+
+First-time pairing uses `/pairing`. The extension generates an origin-bound ECDSA P-256 installation identity and keeps its non-extractable private key in IndexedDB. Yak keeps a persistent engine identity under the Yakit home directory with owner-only file permissions. The plugin and Yakit derive the same six-digit code from both nonces, identities, origin and public keys; the user approves only after comparing that code. No bearer token is stored or copied.
+
+The browser-profile `installationId` is stable across disconnects and local unpairing; clearing a pairing destroys the local signing key but does not manufacture a new browser installation. A later approved pairing with the same installation ID rotates the public credential in place while preserving the Yak `deviceId`, user-visible name and creation time. If browser storage was actually erased and a new installation ID is unavoidable, Yakit must explicitly choose whether to replace a matching offline identity or add a separate browser profile. Replacement is restricted to the same extension origin and client, so a shared Chrome extension ID is never used as an unsafe global deduplication key.
+
+Every `/extension` connection starts with a signed engine challenge. The extension verifies the approved engine public key and replies with a signature from its paired installation key. Yak verifies both the installation ID and browser extension Origin before returning `hello_ack`. The connection is not reported ready until that acknowledgement confirms protocol, capabilities, engine identity, engine instance, connection and session identities. The authentication message also carries the current task/grant identity. A disconnected installation can resume its logical session while each physical connection receives a new ID. Revoking a device immediately closes its active connection. Heartbeats carry sequence/timestamps and expose round-trip latency.
+
+Request IDs allow concurrent calls in both directions. The extension accepts at most eight engine-initiated in-flight requests, rejects duplicate IDs, supports cancellation, and applies a 16 MiB aggregate limit. Messages above 512 KiB are split into bounded 256 KiB chunks with transfer count/timeout limits. Yak forwards context cancellation and buffers extension events in a bounded queue exposed as `browser.ExtensionWaitEvent`.
+
+### Yakit device tasks
+
+Pairing and device CRUD remain on `RequestYakURL`. Executable work uses one server-streaming RPC, `ExecuteBrowserExtensionTask`, with stable routing fields (`task_id`, `device_id`, `schema`, JSON payload and timeout). The stable schemas are:
+
+- `capability.call`: invokes one extension capability with `{method, params}` and returns its JSON result;
+- `yak.script`: executes Yak in the owning gRPC process and injects a request-bound `browser.ExtensionCall` and `browser.ExtensionStatus` for the selected device.
+
+Yakit treats `capability.call` as a schema-controlled command channel rather than adding one gRPC method per browser feature. Its selected-device workspace defaults to a browser-workflow view with Plaintext Gateway, Recorder and Deep Capture modes; raw capability JSON and Yak scripts remain advanced modes. Recording, `browser.callable.*`, `browser.deep_capture.*` and `browser.transform.*` calls therefore use the same streamed task lifecycle, cancellation, device routing and output limits as every other extension capability.
+
+The engine supports multiple simultaneous browser connections. Calls are routed by paired device ID, pending responses are bound to the target WebSocket, and a disconnect immediately fails that device's outstanding calls. A schema handler cannot silently fall back to another online browser.
+
+Task events use a small common vocabulary (`queued`, `running`, `log`, `result`, `warning`, `error`, `cancelled`, `completed`) with monotonic sequence and timestamp fields. The RPC bounds payload size, timeout, concurrent scripts, per-event data and aggregate output; cancelling the stream propagates through the Yak context to the extension request.
+
+The Yak runner is a controlled in-process context, not an operating-system sandbox. It prevents process exit, recovers VM panics and enforces resource bounds, but only trusted operator-authored code should use it. Untrusted or remotely supplied scripts require a future isolated worker. The generic `ExecYakScript` path is intentionally not reused because its child process does not own the parent process's live Bridge manager.
+
+Native Messaging uses the same Bridge v3 challenge/auth envelope and paired identity contract:
+
+```text
+Browser extension -> registered Yakit Native Host -> loopback Yak Bridge -> running Yak engine
+```
+
+The Yak repository contains `common/browser/nativehostcmd`, a stdio framing proxy with loopback/origin validation. `native-host/install.sh` and `install.ps1` register per-user Chrome/Chromium/Edge/Brave/Firefox manifests. `nativeMessaging` is optional and requested only when the user explicitly saves Native mode.
+
+## Human takeover
+
+Agent workflows treat human participation as an explicit, persisted state transition:
+
+1. The agent detects a QR code, MFA prompt, CAPTCHA, or device confirmation.
+2. It calls `browser.handoff.request` for a document in the active control grant.
+3. The extension focuses the tab, shows a badge, expands the target page panel, and displays the same request in Popup and Options.
+4. The Agent pauses without polling sensitive content.
+5. The user chooses **操作已完成** or **取消任务**.
+6. The extension emits `browser.handoff.changed`; Yak receives it through `ExtensionWaitEvent`.
+7. The Agent matches the handoff ID, captures a fresh context, and continues only after `completed`.
+
+`browser.takeover` remains a short-lived focus action without a completion lifecycle.
+
+## Network capture
+
+Network capture uses the browser `webRequest` API rather than page-world Fetch/XHR monkey patches. This preserves the actual outgoing request headers, browser-added Cookie header, request body, redirect status, cache state, and timing. The listener is filtered to Fetch/XHR, ping, and related programmatic requests; images, stylesheets, scripts, fonts, and media are not collected.
+
+Each capture session is bound to one tab, frame, and document. Chrome MV3 stores the bounded session in `storage.session`, so Service Worker suspension does not move sensitive records into persistent settings. Firefox MV2 keeps the same data in background memory. Defaults are metadata-only, 100 entries, and no request headers or body. Explicit sensitive capture is capped at 200 entries and 64 KiB per request body; the UI currently uses 100 entries and 32 KiB.
+
+Generating a replay packet requires captured request headers. The packet is reconstructed as HTTP/1.1 with the observed header values and bounded body bytes. Truncated or omitted bodies produce an explicit limitation warning. Sending to Yakit is a confirmed Bridge request: Yak validates a maximum 2 MiB packet, saves a Web Fuzzer page configuration in the current project database, broadcasts the new tab to Yakit, and returns its `pageId` before the extension reports success.
+
+## Browser recording and page callables
+
+The independent `page-recorder-main-world.js` entrypoint temporarily wraps user-visible interactions, Fetch, XHR, form submission, Beacon, WebSocket, Worker/SharedWorker/MessagePort boundaries, a crypto-adapter registry, `btoa`, and `atob`. WebCrypto, CryptoJS, JSEncrypt, sm-crypto, and node-forge feed one open-but-bounded `crypto` event contract rather than library-specific event kinds. Worker and MessagePort round trips inherit their originating Trace through a bounded channel context, but are explicitly labeled `correlated` rather than being misrepresented as exact value equality. It does not replace `webRequest`: recording explains page-side data flow, while network capture preserves the browser's actual outbound request.
+
+Each click or submit begins a five-second business Trace. Nested and subsequent events share that Trace. Inputs and outputs are reduced to bounded evidence paths, byte lengths, encodings, and a randomly seeded 64-bit correlation fingerprint. The seed remains inside one page document and is regenerated for every document observer, so fingerprints cannot be compared across document boundaries. Matching an earlier output fingerprint to a later input fingerprint creates an exact Pipeline link. This is evidence of value equality inside one document segment, not proof of semantic causality.
+
+Raw previews are disabled by default. Enabling them requires `browser.recording.sensitive.read` and caps each preview at 8 KiB. A user-started recording is a tab/frame-scoped Session: the current document keeps live hooks and handles, while the background merges bounded document segments into extension-only `storage.session`. A full navigation is recorded as a first-class Trace event; the previous segment is sealed, the destination document receives a new observer with the same Session identity and a synchronized global sequence, and recording continues until explicit stop, expiry, clear, or tab close. The single per-target Session is removed by a new recording, explicit clear, tab close, or browser-session end. Previews are never written to persistent storage or included in audit or AI request-analysis payloads. Recording is bounded to 500 aggregate events, 48 evidence items per side, 1,000 links, and 64 live callable handles per document.
+
+Navigation is both a business event and a strict execution-context boundary. Full document navigation, reload, browser Back/Forward, same-document History changes and fragment changes are distinguished. If Back/Forward restores the original document from BFCache, its recorder, handles and callables are resumed without clearing earlier evidence; if the browser performs a hard reload, the historical evidence remains but the destroyed closure heap is truthfully unavailable. MAIN-world lifecycle and the tab-scoped Session are separate states, so a temporary document transition no longer appears as a completed recording. A grant-owned recording remains document-bound and stops at navigation instead of silently extending an Agent's authority into a new document.
+
+When an observed stateless or receiver-bound operation can be replayed, the recorder retains an opaque reference to the original function, actual receiver, argument template, and non-extractable `CryptoKey` or library key object. Stateful and streaming node-forge sessions instead expose correlated create/init/update/final evidence and direct the user to retain their one-shot business wrapper. Creating a `BrowserPageCallable` places only metadata and a named data slot in the shared current-document registry; key material remains in the retained call template. Library adapters expose only key kind, modulus size, and a document-salted fingerprint—never PEM/private-key material, modulus, exponent, or an instance. Retained call handles are bounded by count, a 2 MiB per-handle limit, and an 8 MiB aggregate limit; oversized calls remain visible as metadata but cannot pin their arguments as replay handles. A manual stop restores wrapped APIs but keeps callables usable in the same live document. Navigation or refresh destroys the page heap and intentionally invalidates every handle. Clear, grant expiry, and grant revocation restore APIs and destroy events, retained handles, and recorded-call entries.
+
+Inference is request-centered. One exact crypto-output-to-request-field edge plus a live handle can produce a ready profile directly, including JSEncrypt RSA into form, JSON, header, query, or raw body destinations. Multiple crypto outputs in one request become one request-level candidate. Even when every edge is exact, those primitives are not replayed separately because AES keys, RSA-wrapped keys, IVs, nonces, signatures, and timestamps may share one dynamic business context; Deep Capture is required to retain that higher-level callable. Known-library adapters are semantic accelerators rather than the generality boundary: ESM/bundler closures, Worker/WASM paths and unknown business wrappers must remain usable through request/message boundary evidence and business-callable capture even when the algorithm cannot yet be named. The adapter refactor, high-value provider order and anti-fixture acceptance matrix are defined in [`docs/FRONTEND_CRYPTO_GENERALIZATION_ROADMAP.md`](docs/FRONTEND_CRYPTO_GENERALIZATION_ROADMAP.md).
+
+Options and Yakit expose the same Session -> Trace -> event/evidence/callable model. The UI uses one oldest-to-newest recording timeline, numbered execution cards and relative timestamps. A neutral vertical rail communicates execution order; exact value links use a separate success treatment so temporal order is never mistaken for data-flow proof. Navigation cards show source, destination, lifecycle phase and document availability. The workspace validates a callable with new arguments before it is used by a Yak or AI workflow.
+
+## Chromium Deep Capture and business callables
+
+The Recorder remains the low-overhead discovery layer. When a Trace identifies the relevant unified crypto call or request, Chromium Deep Capture attaches through `chrome.debugger`, enables the Runtime/Debugger/DOMDebugger domains and installs one one-shot breakpoint. Crypto matching uses `Debugger.setBreakpointOnFunctionCall` on the real installed adapter wrapper function, so production minification and page CSP cannot remove or block the breakpoint. Request matching uses a bounded XHR/fetch URL substring.
+
+Pause processing is two-stage. The background publishes at most 14 call-frame skeletons immediately, schedules a 45-second alarm watchdog, then reads up to six local/closure/module scopes for the first eight frames in parallel. UI keepalive extends the deadline; loss of all control surfaces resumes the page. Status, keepalive, resume, detach and adapter creation use only grant identity, `webNavigation`, session state and CDP while paused. They never inject a script into the paused document, avoiding a control-plane deadlock.
+
+`browser.callable.create` with `source: deep-capture` defaults to a backend-trusted `selected-frame` strategy. Multi-source stack hints and deterministic CDP inspection select a unique page business frame, resolve its real function object from the frame name, receiver descriptor or scope binding, verify its function location and block network/DOM/navigation/storage side effects. A user expression is an advanced fallback and passes the same gate. The resulting function and receiver enter the same page-owned callable registry used by recorded calls; metadata alone crosses the extension boundary. Formal parameters, including those after default values, become ordered input slots. Options can use exact same-name values already present in the authorized paused scope to initialize a non-persistent local replay sample and `body.<parameter>` guide. After resume, `browser.callable.execute` invokes that closure with at most 64 JSON arguments and returns a bounded structured result. Non-extractable keys, key promises and other closure objects remain in the page. Navigation destroys every callable.
+
+Debugger read, debugger control and callable execution are separate scopes. A grant cannot control a local or different grant's debugger session. Replacement, expiry, revocation and tab closure release owned sessions. Firefox does not request `debugger` or advertise Deep Capture, but it can retain recorder-created page callables. Detailed invariants and real AES-GCM/HMAC acceptance criteria are in [`docs/DEEP_CAPTURE_ARCHITECTURE.md`](docs/DEEP_CAPTURE_ARCHITECTURE.md).
+
+## Browser Transform Gateway
+
+The Transform Gateway turns retained page callables into a native Web Fuzzer data plane. Yakit keeps the request and response editor in plaintext. The owning Yak gRPC process calls the selected paired browser after the user's `beforeRequest` hot patch and before network transmission, then calls it again immediately after receiving a response and before the user's `afterRequest` hot patch. `RequestRaw`/`ResponseRaw` remain logical plaintext; `WireRequestRaw`/`WireResponseRaw` preserve the actual transmitted packets for side-by-side inspection and history.
+
+Profiles are bound to one current `tabId + frameId + documentId + origin`, route-filtered by HTTP method and wildcard URL, and composed as a Pipeline v2 ordered DAG of `context.read`, whitelisted `builtin`, `page.call` and `output.write` nodes. Nodes may reference only earlier results. After the background validates route, origin and document identity, the complete bounded DAG executes in the target MAIN world with one extension-to-page round trip rather than one round trip per node. Outputs support complete/field-level bodies, headers and query parameters. Paths reject prototype traversal, header mappings reject CR/LF injection, and Yak independently rejects any returned URL that changes scheme, host, port or path. Execution values are lossless within an 8 MiB body limit and fail explicitly outside their structural bounds. A bounded per-profile gate protects page functions that are not safely re-entrant.
+
+Request conversion is fail-closed: no error path sends the plaintext packet. Response conversion failure returns an explicit synthetic failure while retaining the wire response for diagnosis. Navigation, refresh, grant expiry, callable loss, route mismatch and browser disconnect never silently retarget or fall back. Chromium exposes the workspace because Deep Capture can retain business closures; Firefox hides the unavailable Gateway/Deep Capture modes.
+
+The complete product contract, schema, ordering and acceptance fixture are documented in [`docs/BROWSER_TRANSFORM_GATEWAY.md`](docs/BROWSER_TRANSFORM_GATEWAY.md).
+
+## Page-world code
+
+### Structured context and node references
+
+`browser.context` no longer returns a full HTML document. A snapshot contains a 20 KiB body-text excerpt, bounded headings/forms, up to 400 actionable nodes discovered while scanning at most 10,000 elements, a full frame inventory, optional bounded Web Storage values, optional IndexedDB database/store/key metadata, optional CacheStorage names, bounded document/SPA lifecycle events, optional Cookie values, authentication signals, and a diff against the preceding snapshot for the same tab/frame. IndexedDB and Cache values are never collected. Open Shadow Roots are traversed recursively; the extension's own edge-panel Shadow Root is excluded.
+
+Each actionable element is registered in the page's MAIN world and identified by `captureId + tabId + frameId + documentId + nodeId`. `browser.node.inspect` and `browser.node.action` resolve the registered `Element` directly instead of re-running a CSS selector. A new capture replaces the registry, a detached element is rejected, and a changed document fails target resolution. These paths return `stale_node` or `stale_document`; they never silently retarget a similar element.
+
+Frame inventory combines `webNavigation.getAllFrames` with a bounded packaged probe in every accessible frame. Grants store an explicit target for each selected `tabId + frameId + documentId + origin`; selecting a tab authorizes only its main frame until the user separately selects child frames. `webNavigation.getFrame` verifies each remote operation against the current frame URL and document. Cross-origin navigation returns `origin_changed`, while same-origin document replacement returns `stale_document`.
+
+Node inspection returns bounded identity, safe attributes, visibility, state, and viewport bounds. It deliberately excludes the current input value. Node actions support `click`, `focus`, `scroll`, and `setValue`; `setValue` uses native value setters plus input/change events, rejects file inputs, requires `browser.dom.write`, and never sends the supplied value to the audit writer. Programmatic click is a page-world click and is not represented as a trusted physical mouse event.
+
+The authentication classification is a heuristic based on bounded DOM controls plus explicitly requested Cookie names and Storage keys. It is useful for workflow routing, but it is not proof that the server accepts the current session.
+
+`PageExecutionAdapter` selects an execution mechanism at build time. Production/store Chrome builds use the Web Store-permitted User Scripts API:
+
+```text
+Background capability router
+    -> userScripts.execute({ world: "MAIN" })
+    -> structured { ok, result | error }
+```
+
+The default production build declares Chrome 138+, requires the user to enable Allow User Scripts, and physically omits `page-main-world.js`. It never silently falls back to direct Eval.
+
+User Scripts receive the selected expression or program as direct script source; the Store path never calls `eval` on Bridge-provided text. Expression mode automatically returns its expression. Program mode is an async function body and requires an explicit `return` to produce a value; without one it returns `undefined`.
+
+Development and local Firefox MV2 builds use WXT's packaged injection pattern. Enterprise Chrome prefers User Scripts and retains this pattern only as a managed fallback:
+
+```text
+Background capability router
+    | tabs.sendMessage (extension-only)
+Isolated content script
+    | correlated CustomEvent on the injected script element
+Unlisted page-main-world script
+    | indirect eval / function invocation
+The page's real window context
+```
+
+The old extension established the essential behavior by injecting `inject.js` and forwarding `CONTENT_EVAL_CODE` through `window.postMessage`. The current bridge preserves that capability while adding request IDs, Promise resolution, response timeouts, error propagation, cycle-safe result serialization, output limits, and content-script lifecycle cleanup. A timeout stops the extension from waiting for an asynchronous result; JavaScript cannot safely interrupt synchronous code, so an infinite loop can still block the target page.
+
+Both adapters share the same expression/program return rules, result serializer, Promise behavior, timeout bounds, and error envelope. Local Eval is initiated by an explicit user action. Remote expression and program modes require separate scopes and a target whose tab, frame, document and origin still match. Because the page controls its JavaScript environment, all results remain untrusted input.
+
+The public Firefox MV3 AMO channel is invoke-only at the extension boundary: it requests neither `userScripts` nor general page invocation/Eval, does not package `page-main-world.js`, and advertises neither Bridge capability. This follows Mozilla's current restriction of `userScripts` to user-script managers. Structured context, stable node commands, network capture, browser recording and human handoff remain available.
+
+The same page bridge supports `browser.invoke` for the narrower case where the Agent already knows a concrete global function path. Browser recording uses the same target/grant boundary through a separately packaged, bounded MAIN-world recorder and does not depend on general Eval.
+
+## Proxy routing
+
+Proxy routing is a compile-and-apply subsystem, not an extension-side per-request rules engine. Durable endpoint/rule/source summaries remain in `settings.proxy.v1`; downloaded source revisions, normalized 512-rule chunks, and the eight newest compiled artifacts live in `yakit-proxy-rules` IndexedDB. Large exact/suffix host sets compile to PAC tries, while wildcard and regex conditions are instantiated once outside `FindProxyForURL`.
+
+Automatic order is manual rules, ordered sources, then the default endpoint. Source exclusions run before positive rules unless a SwitchyOmega `@with result` list explicitly owns file order. Rule-source updates stage a new revision and only replace the state reference after parse, compilation, `browser.proxy.settings`, and serialized state commit succeed. The last live PAC and source revision remain active on failure.
+
+Yakit MITM is a built-in fixed endpoint, not a remotely managed MITM process. Popup keeps two operations visually and behaviorally separate: a current-hostname assignment can target any Direct or fixed HTTP(S)/SOCKS endpoint and atomically enables automatic routing, while the global mode list changes the entire browser without creating a rule. “Automatic” clears the exact-host override so subscriptions and the default endpoint resume control. The extension does not control Yak MITM lifecycle or downstream interception policy. Full formats, budgets, failure behavior, and verification requirements are documented in `docs/PROXY_ARCHITECTURE.md`.
+
+## Popup and Options tool boundary
+
+The popup is the current-tab command surface. It uses a fixed 48px icon rail with four modules: overview, proxy, Cookie Editor and User-Agent. The Yak SVG mark remains visible in the header without repeating the full product name. Bridge state is represented by a focusable status dot with a tooltip and explicit accessible label; green means connected, amber means connecting/negotiating, gray means unpaired or offline, and red means an error.
+
+Cookie Editor and User-Agent are exposed as rail modules for actions that should complete in one or two steps:
+
+- Cookie values are masked by default and only revealed by an explicit click; the quick editor supports the common name/value/path/SameSite/flag fields and preserves existing partition metadata.
+- User-Agent quick switching offers browser default, built-in device templates and saved custom profiles, then applies the selected header to the current hostname and reloads the target tab.
+- Both quick views report the current target hostname and link to the full Options tool. They never implement a second browser API path; all reads and mutations use the typed runtime request map.
+
+Options is the durable management surface. Its `常用工具` navigation group contains the full Cookie Editor and User-Agent manager, including filtering, import/export, CHIPS fields, per-host assignments, custom profile editing and deletion. This split keeps the popup small enough for repeated use while retaining the security controls and information density required for deep workflows.
+
+## Page UI loading
+
+The content script is a roughly 10-12.2 KiB native DOM shell. It owns the Yak launcher, bridge indicator, drag position, left/right snapping, and handoff-triggered expansion. React, Radix, and the floating workbench are loaded in `floating.html` only after the user expands the launcher or a handoff targets that tab; the iframe is released after 60 seconds collapsed. Build auditing reports the content-script size as an advisory trend; lazy loading and the 60-second release policy are verified from runtime behavior rather than enforced through a fixed bundle-size gate.
+
+Popup, Options, and the floating workbench share one token-based design system in `src/styles/`: `tokens.css` defines the palette, type scale (11-20px), radii, and shadows, including a full dark set under `[data-theme='dark']`; `ui.css` styles the shared Radix-backed components. The vivid brand orange is reserved for non-text accents; filled primary buttons and text links use a deeper AA-contrast orange. All surfaces are light-first — the orange yak mark is shown bare without a backing tile. The theme preference (`system`/`light`/`dark`) lives in its own `settings.appearance.v1` local-storage key, is written only from extension UI, and is applied to `<html data-theme>` by each entrypoint through `src/platform/storage/appearance.ts`; the content-script launcher reads the same key in-page (falling back to the OS scheme) to theme its shadow-DOM shell.
+
+## Audit boundary
+
+Audit events live under a separate storage key and are serialized independently from settings and active session state. The bounded log retains the latest 500 events. It records category, method/action, outcome, task ID, tab ID, duration, error code, and a fixed safe summary where applicable. Capability parameters and results are never passed to the audit writer. The Options activity view reads the latest 200 entries and lets the user clear them locally.
+
+## Production operations
+
+- State v7 uses separate durable proxy/UA/Bridge/panel keys and separate session grant/Bridge/action keys; mutation is serialized across domains and no legacy migration path exists.
+- Agent actions have a session timeline and user pause/resume/revoke controls. Persistent audit remains metadata-only.
+- Managed storage can lock transport, endpoint/host, grant duration/origins, program Eval and panel availability. Enforcement is in background handlers.
+- Aggregate Service Worker, Bridge, heartbeat and capability metrics stay local. Explicit diagnostics export omits URLs, values, payloads, Eval code and task/grant identifiers.
+- Public review artifacts live under `docs/store-review`; privacy, permission and enterprise deployment contracts live under `docs/`.
+- Store/Enterprise Chromium E2E covers 320/390/desktop UI, service-worker restart, frame/document/origin boundaries, request/recording workflows, exact value and correlated channel links, document callable replay, all five crypto adapters, node-forge stateful sessions, independent SM2/SM4/RSA/AES/digest/HMAC/signature validation, randomized non-global ESM + WebAssembly closure recovery, Worker holdout, recorder load/memory budgets, JSEncrypt RSA receiver retention and guided form-field profiles, distinct WebCrypto operation breakpoints, real closure-held AES-GCM/HMAC request encryption, encrypted-response restoration and server validation, handoff, audit/diagnostic redaction and state concurrency. Go tests cover Bridge v3 pairing, code derivation, signed challenge/auth, revocation, YakURL control, chunking/session recovery, transform URL confinement and Native Messaging proxy framing.

+# Design System: Yakit Browser Agent
+**Project ID:** yakit-chrome-client (derived from codebase design tokens, `src/styles/tokens.css` — no Stitch project)
+
+## 1. Visual Theme & Atmosphere
+
+A **focused security instrument panel**: utilitarian, information-dense, and calm. The aesthetic philosophy is "console first, chrome second" — content surfaces stay quiet and neutral so that state (connection, capture, risk) can carry all the visual signal. The mood is airy-but-dense: compact 13px typography and tight 8px-rhythm spacing, balanced by generous card padding and breathing room between functional groups.
+
+The brand presence is deliberately restrained: a light, continuous surface carries every view, signed by the bare orange yak mark and a single ember-orange accent reserved for moments of genuine emphasis. Nothing glows, nothing gradients, no black slabs; depth comes from whisper-soft shadows and hairline separators, not borders. The system ships in twin themes — a cool light canvas and a true-dark console — with identical geometry and hierarchy, switched by a user preference (`system` / `light` / `dark`).
+
+## 2. Color Palette & Roles
+
+### Light theme (default)
+
+- **Canvas Mist (#f3f4f6)** — application background; lets white cards float without borders.
+- **Card White (#ffffff)** — primary content surfaces: cards, tables, panels, inputs.
+- **Inset Pebble (#eceef1)** — recessed fills: stat tiles, code-free inset areas, toggle-off track.
+- **Ink (#1d232a)** — primary text and strong values.
+- **Slate Note (#68727d)** — secondary text, descriptions, timestamps.
+- **Label Slate (#474f59)** — field labels, section labels, ghost-button text.
+- **Hairline (#e1e4e8)** — non-structural separators (table rows, list dividers); used sparingly.
+- **Frame Line (#c8cfd6)** — input strokes and secondary-button outlines.
+- **Yak Orange (#ee7815)** — brand accent for *non-text* signal only: toggle-on tracks, active nav indicator, icon highlights, focus halo. Never carries text.
+- **Ember (#b54f08)** — the accessible action orange: filled primary buttons (white text, 5.1:1 AA) and text links on light surfaces.
+- **Ember Deep (#9e4607)** — hover state for filled primary buttons.
+- **Ember Wash (#fdf0e1)** — soft selection tint: active list rows, selected table lines.
+- **Pine (#1e7f52)** on **Mint Mist (#e4f3eb)** — connected, captured, success states.
+- **Umber (#94650d)** on **Parchment (#fcf2d9)** — warning states and the human-handoff surface.
+- **Brick (#bf3d3d)** on **Blush (#fbeaea)** — destructive actions, errors, failed states.
+- **Bare Yak (the orange brand mark, #f97a04 family)** — shown directly on the surface with no backing tile; it is the only persistent brand signature.
+
+### Dark theme (`[data-theme='dark']`)
+
+- **Deep Space (#0e1116)** — application background; true console dark, not navy.
+- **Panel Slate (#161b21)** — cards and surfaces.
+- **Raised Slate (#1e242c)** — inset fills and hover states.
+- **Fog Text (#e2e7ec)** — primary text; **Ash (#8a949f)** secondary; **Mist Strong (#b2bcc5)** labels.
+- **Ember Glow (#f5832a)** — filled primary buttons with **Roasted Ink (#201205)** text (7.5:1 AA); brighter than light theme to hold contrast on dark.
+- **Ember Light (#f7a15c)** — text links and code accents on dark surfaces.
+- Semantic tints deepen to translucent darkness: **Pine Glow (#45b981 / #122a1f)**, **Amber Glow (#d9a441 / #2c2311)**, **Coral Glow (#e06e6e / #2f1b1b)**.
+
+## 3. Typography Rules
+
+- **Family:** A system-native sans stack (Inter falling back to ui-sans-serif, system-ui, PingFang SC, Hiragino Sans GB, Microsoft YaHei, Noto Sans CJK SC) — chosen for crisp CJK rendering at small sizes without bundling font files. Code and packets use a mono stack (ui-monospace, SF Mono, Consolas).
+- **Scale (six steps, no more):** 11px for uppercase micro-labels only, 12px secondary/description, **13px as the reading base**, 14px emphasized values, 16px section titles, 20px page titles.
+- **Weight hierarchy:** 500 for navigation, 600 for interactive text and labels, 650 for card titles and strong values, 700 reserved for page titles and hero numerals.
+- **Micro-labels:** 11px, weight 650, letter-spacing .04em, uppercase, Slate Note color — the "eyebrow" voice used above data.
+- **Rhythm:** line-heights stay tight (16–18px for body); Chinese text is never set below 12px except uppercase micro-labels.
+
+## 4. Component Stylings
+
+* **Buttons:** 36px tall with gently squared corners (6px radius) and 13px semibold labels. The *filled primary* is Ember (light) / Ember Glow (dark) with contrasting text — strictly one per view. *Secondary* buttons are Card White with a Frame Line stroke. *Ghost* buttons are transparent until hovered. *Danger* is a Brick outline that fills with Blush on hover. Small (30px) and icon (34px square) variants share the same geometry.
+* **Cards/Containers:** Generously rounded corners (12px radius), Card White fill, and a whisper-soft two-layer shadow (a 1px key line of shade plus a faint 4px lift) — no borders. Recessed stat tiles inside cards use Inset Pebble with softly rounded corners (8px). Nothing nests a shadowed card inside another.
+* **Inputs/Forms:** 36px tall, 6px corner radius, 1px Frame Line stroke on Card White; textareas keep the same stroke. Focus never shows a hard outline — instead a soft ember halo (3px of translucent Yak Orange). Field labels are 12px semibold Label Slate; hints in 12px Slate Note.
+* **Toggles:** Pill-shaped switches (40×22px), Pebble track when off, Yak Orange track when on, white 16px thumb gliding on a short ease.
+* **Navigation rail:** A 238px rail in the same surface as the workspace, separated by a single hairline. Items are 40px rows with softly rounded corners (8px); the active item shows a subtle raised fill plus a 3px inset Yak Orange indicator bar on its leading edge, with its icon tinted orange.
+* **Status pills:** Fully rounded (pill-shaped, 999px) badges pairing each semantic color with its soft wash — connected/capturing in Pine-on-Mint, waiting/warning in Umber-on-Parchment, error in Brick-on-Blush.
+* **Code & packets:** Deep slate panels (#171b20, light mono text) with 8px rounded corners; they remain dark in both themes as "terminal territory."
+* **Handoff surface:** A Parchment card with a 3px Umber leading edge and the warning icon — the single interruptive pattern in the system, reserved for QR/MFA/CAPTCHA human takeover.
+
+## 5. Layout Principles
+
+- **Shell:** A fixed 238px dark rail plus a fluid workspace. The workspace column is capped at a comfortable 1440px reading width and **horizontally centered**, so ultra-wide monitors frame the console instead of stretching tables into unreadability.
+- **Grid alignment:** The 60px sticky topbar shares the exact content grid — its padding is computed from the same 1440px cap (`max(28px, (100% − 1440px)/2 + 28px)`), keeping the target-tab chip and the page content on one vertical line.
+- **Spacing rhythm:** An 8px base unit; 16px gaps between cards, 16–20px inner card padding, 22–28px page padding. Groups are separated by space and shadow, not rules.
+- **Two-column workbenches:** Data pages (network, cookies, context, engine) use a fluid primary column with a 320–440px inspector column that sticks below the topbar; below 1080px they stack to a single column.
+- **Grid discipline:** Every single-column vertical grid declares an explicit `minmax(0, 1fr)` track, so long URLs and code strings truncate with ellipses instead of overflowing narrow (320–390px) viewports.
+- **Popup:** A fixed 390px single-sheet column — sections divided by hairlines, not floating cards — designed to a strict 600px height budget, keeping every action including the bottom primary capture button visible without scrolling.
+- **Floating panel:** A 46px edge launcher — a white stadium orb with the bare yak mark (dark in dark theme, theme-aware in-page) — that expands to a 326px rounded workbench over the page; its header shares the panel surface with a single hairline seam.
+- **Motion:** Short (140–180ms) ease transitions on color and slide only; `prefers-reduced-motion` collapses all animation.

+
+## 项目定位
+
+Yakit Browser Agent 是 Yak / Yakit 生态中的浏览器执行端。它运行在用户真实使用的浏览器里，在用户明确授权后，将特定标签页的页面上下文、安全测试能力和人工交互能力提供给 Yak 引擎、Yakit 工作区以及 AI Agent。
+
+它重点解决传统安全测试工具难以自然处理的几类问题：
+
+- 目标功能依赖已经登录的浏览器环境，无法仅靠离线 HTTP 请求复现；
+- 请求参数由混淆后的前端代码、闭包状态、动态密钥、`CryptoKey`、Worker 或 WebAssembly 现场生成；
+- 测试者希望编辑明文，但目标服务器只接受页面产生的密文、签名或动态请求封装；
+- 流程包含扫码、MFA、CAPTCHA、设备确认等必须由用户参与的步骤；
+- 双身份授权测试需要可靠隔离登录态、复用真实请求并保留可复核证据；
+- AI Agent 需要浏览器提供真实、结构化、受控的上下文，而不是依赖截图猜测或导出完整浏览器配置。
+
+本项目并不是只针对某个靶场编写的加解密脚本，也不是一个简单的 JS-RPC 转发器。它以通用的调用证据、业务 Trace、请求边界、页面 Callable 和类型化 Pipeline 为基础：能由确定性证据完成的步骤交给代码验证，证据不足或语义复杂的部分再交给用户与 AI 辅助分析。
+
+## 设计原则
+
+| 原则 | 说明 |
+| --- | --- |
+| 真实现场优先 | 复用页面正在运行的函数、receiver、闭包和浏览器状态，不要求先把密钥或完整算法导出到外部。 |
+| 证据驱动 | 通过值指纹、调用顺序、业务 Trace、请求字段关联和响应归属建立结论，不因“发现某个加密库”就直接猜测转换逻辑。 |
+| 用户明确授权 | 所有远程能力绑定具体标签页、Frame、文档、来源、任务、权限范围和有效期，授权可见、可暂停、可撤销。 |
+| 确定性验证与 AI 协作 | AI 用于解释、归纳和提出方案；协议校验、Profile 编译、真实回放和结果比较由确定性代码完成。 |
+| 通用能力优先 | 对库、算法和业务形态建立适配层，不以固定字段名、固定接口或单一靶场流程作为产品逻辑。 |
+| 本地与性能优先 | 大型代理规则使用 IndexedDB 分块存储和编译缓存；敏感页面数据默认短时保留，诊断与审计只记录必要元数据。 |

+
+## 核心能力
+
+### 1. 前端加解密录制与明文网关
+
+这是 Yakit Browser Agent 的核心工作流。测试者只需要在真实页面完成一次尽可能短的业务操作，扩展会从页面输入、密码调用、编码转换、通信边界和最终请求中还原数据流。
+
+主要能力包括：
+
+- 录制 Fetch、XHR、表单导航、Beacon、WebSocket、Worker、SharedWorker 和 MessagePort 等业务边界；
+- 记录加解密调用的输入、输出指纹、调用栈、receiver、固定参数模板与请求先后关系；
+- 将同一业务动作组织为按时间排序的 Trace，区分页面原始函数与扩展注入的观测 Hook；
+- 自动推断明文来源、密码调用和线上请求字段之间的关联；
+- 在证据充分时直接生成请求或响应方向的明文网关；
+- 在普通录制无法保留状态时，使用 Chromium Deep Capture 捕获闭包、模块脚本、`CryptoKey`、WebAssembly 实例或多调用请求事务；
+- 将捕获到的业务调用保存为文档绑定的页面 Callable，无需向外导出页面密钥；
+- 使用类型化 Pipeline 组合上下文读取、页面调用、白名单转换、字段装配和输出写入；
+- 在本地回放中使用录制的短时样本验证转换关系；
+- 与 Yakit Web Fuzzer 联动：编辑逻辑明文，由真实页面生成线上密文或签名，同时并排查看“明文 / 线上”报文。
+
+当前观测与推断适配层覆盖：
+
+- Web Crypto API；
+- CryptoJS；
+- JSEncrypt；
+- jsrsasign；
+- node-forge；
+- sm-crypto；
+- JOSE；
+- libsodium；
+- TweetNaCl；
+- Noble；
+- OpenPGP。
+
+适配器用于识别通用调用语义，并不意味着所有混淆代码都可以无条件自动还原。自动化程度取决于录制证据是否能够证明“明文输入 → 页面调用 → 请求字段”或“线上响应字段 → 页面调用 → 明文输出”的完整链路；证据不足时，界面会明确展示缺失环节，并引导进入深度捕获或 AI 辅助分析。
+
+### 2. 登录态上下文与 AI Agent 协作
+
+扩展可以把用户明确共享的浏览器页面转换为适合 Agent 使用的结构化上下文，而不是直接导出完整 HTML 或浏览器 Profile。
+
+- 采集页面文档信息、认证信号、表单、交互元素、开放 Shadow DOM、Storage 与 Cookie 清单；
+- 使用文档绑定的节点引用执行检查、点击、聚焦、滚动和输入等操作；
+- 追踪上下文差异，帮助 Agent 判断登录、跳转和业务状态变化；
+- 在独立权限下调用页面已有函数，或执行表达式与程序级 Eval；
+- 捕获已授权文档的真实网络请求，并生成可在 Yakit 中重放的报文；
+- 将录制 Trace、Callable、Transform Profile、请求事务和验证结果作为 Agent 工具能力；
+- 在 Agent 遇到扫码、MFA、CAPTCHA 或设备确认时创建“人工接管”任务，聚焦目标标签页并等待用户完成后继续。
+
+程序级 Eval、敏感网络字段、深度捕获和页面控制均属于高风险 Scope，不会被只读共享会话隐式包含。
+
+### 3. 双身份水平与垂直授权测试
+
+授权测试工作区用于组织两个真实登录身份，并以可复核的方式验证资源访问或权限动作。
+
+- 在普通窗口、无痕窗口或其他受支持的隔离上下文中选择身份 A / B；
+- 校验 Cookie Store、认证材料和页面上下文是否真正隔离；
+- 自动读取双方最近的同类业务请求，建立 A/B 正常基线；
+- 从 Query、Path、Header、表单或结构化 Body 中提取资源候选；
+- 水平授权测试使用固定请求预算构造 A-own、B-own、A-to-B、B-to-A 四项矩阵；
+- 垂直授权测试对比低权限控制请求与高权限目标动作，并明确提示潜在副作用；
+- 对状态码、响应结构、业务字段和目标身份正常响应进行差异比较；
+- 对时间戳、请求 ID 等易变噪声进行归一化，保留可解释的业务差异；
+- 将短时证据包交给 Yakit 与 AI Agent 深入分析，同时避免用插件预判结论暗示 AI；
+- 由确定性证据给出“观察到什么”，由用户、业务规则和独立 AI 复核决定是否构成真实授权缺陷。
+
+扩展不会因为交叉请求返回 `200` 就直接判定越权，也不会绕过真实身份隔离要求。
+
+### 4. 自动代理与规则系统
+
+代理模块面向日常安全测试和多出口切换，交互方式接近现代化的 SwitchyOmega / ZeroOmega 工作流，但针对大规则集和扩展运行时做了重新设计。
+
+- 创建并管理多个代理出口；
+- 为不同域名、URL 模式或规则条件选择指定出口；
+- 支持直连、代理和自动切换情景；
+- 在 Popup 中快速切换当前出口，或为当前站点建立规则；
+- 导入和更新远程规则订阅；
+- 将规则编译为 PAC，并在应用前完成规范化和错误检查；
+- 使用 IndexedDB 按块保存大型规则源，避免把完整订阅反复塞入同步状态；
+- 缓存有限数量的编译产物，并清理过期 Revision；
+- 通过分页与搜索读取规则，不要求一次渲染全部内容。
+
+该模块只决定浏览器请求应当走哪个代理出口。Yak MITM 可以作为其中一个代理出口使用，但扩展不会替用户控制或改变 MITM 内部规则。
+
+### 5. Cookie Editor 与 User-Agent 快速切换
+
+Popup 提供针对当前站点的高频操作，Options 提供完整管理界面。
+
+- 查看、添加、编辑和删除当前站点 Cookie；
+- 支持 Domain、Path、SameSite、安全标记与分区 Cookie 元数据；
+- 支持 Cookie 过滤、导入与导出；
+- 提供常用设备 User-Agent 模板；
+- 创建、保存和删除自定义 User-Agent；
+- 将 User-Agent 分配给指定 Hostname，并立即作用于真实网络请求头。
+
+User-Agent 工具只修改网络请求头，不伪装 `navigator`、Client Hints、屏幕信息、Canvas、TLS 或其他浏览器指纹。界面会明确提示这一边界。
+
+### 6. 安全配对与浏览器共享会话
+
+Yak gRPC 进程内置 Browser Bridge v3，扩展无需额外启动桥接脚本，也不依赖手工复制的长期 Token。
+
+- 首次配对显示六位校验码，由用户同时在扩展与 Yakit 中确认；
+- 扩展生成不可导出的 ECDSA P-256 安装身份，Yak 保存独立引擎身份；
+- 后续连接通过双向身份、签名挑战、扩展 Origin 和安装 ID 完成认证；
+- 支持多个浏览器设备同时在线，并按设备 ID 精确路由任务；
+- 共享会话绑定标签页、Frame、文档、Origin、Task、Scope 和过期时间；
+- 页面刷新、文档替换或跨来源导航不会静默继承原授权；
+- 用户可以随时暂停 Agent、撤销共享会话或在 Yakit 中撤销整个浏览器设备；
+- 审计日志只记录方法、目标类型、耗时、结果和错误码等元数据，不保存 Cookie 值、页面正文、Eval 源码、请求载荷或执行结果。
+
+## 产品界面
+
+| 界面 | 主要用途 |
+| --- | --- |
+| Popup | 查看当前页面与引擎状态；快速切换代理、Cookie 和 User-Agent；进入完整工作区。 |
+| Options | 运行概览、授权测试、代理出口、自动切换、规则订阅、网络活动、Cookie Editor、UA 管理、登录态工作区、引擎连接与操作记录。 |
+| 页面悬浮面板 | 贴近当前页面的轻量操作入口，可吸附屏幕边缘，并在需要时展开代理、接管和任务状态。 |
+| Yakit 浏览器集成 | 管理已配对设备、执行浏览器任务、查看录制与明文网关，并与 Web Fuzzer 联动。 |
+| Yak AI Agent | 调用经过授权的浏览器能力，分析证据、编排流程，并在必须人工参与时等待用户接管。 |
+
+## 快速开始
+
+### 环境准备
+
+完整能力需要以下组件：
+
+- Chrome / Chromium / Edge，或受支持的 Firefox；
+- Node.js 与 pnpm；
+- 包含 Browser Bridge v3 的 Yak 引擎；
+- 包含“浏览器集成”工作区的 Yakit。
+
+仅使用代理、Cookie、User-Agent 等本地工具时，不要求连接 Yak 引擎。
+
+### 安装依赖并启动开发模式
+
+```bash
+git clone https://github.com/yaklang/yaklang-chrome-extension.git
+cd yaklang-chrome-extension
+pnpm install
+pnpm dev
+```
+
+如果浏览器没有自动加载扩展：
+
+1. 打开 `chrome://extensions`；
+2. 开启“开发者模式”；
+3. 选择“加载已解压的扩展程序”；
+4. 加载 `.output/chrome-mv3-dev`。
+
+### WSL 开发
+
+WXT 在 WSL 环境中不会自动打开浏览器。项目提供了单独的启动器：
+
+```bash
+pnpm dev:wsl
+```
+
+开发 Profile 位于 `.wxt/chrome-wsl-profile`。当前稳定版 Chrome 不接受无人值守的 `--load-extension` 参数时，首次仍需在 `chrome://extensions` 手动加载 `.output/chrome-mv3-dev`；之后该 Profile 会记住扩展。
+
+如需指定 Chromium 或 Chrome for Testing：
+
+```bash
+CHROME_PATH=/path/to/chromium pnpm dev:wsl
+```
+
+## 连接 Yak 与 Yakit
+
+在 Yak 仓库中启动 gRPC 引擎：
+
+```bash
+go run common/yak/cmd/yak.go grpc --host 0.0.0.0
+```
+
+标准启动会在 `127.0.0.1:64333` 自动启动 Browser Bridge，无需额外参数。
+
+首次配对：
+
+1. 在 Yakit 打开“系统设置 → 浏览器集成”；
+2. 在扩展 Options 打开“引擎连接”；
+3. 点击“查找本机 Yakit”；
+4. 对比扩展与 Yakit 显示的六位校验码；
+5. 确认一致后，在 Yakit 批准待配对浏览器。
+
+配对完成后，设备身份会持久保存，后续通过签名挑战自动认证。若在 Yakit 中撤销设备，当前连接会立即关闭，浏览器必须重新配对。
+
+非默认部署可以使用：
+
+- `--browser-extension-bridge-port`：修改 Bridge 监听端口；
+- `--disable-browser-extension-bridge`：显式关闭 Browser Bridge；
+- Native Messaging：在浏览器无法直接访问回环 Bridge，或需要受管部署时使用。
+
+Native Host 的构建与注册方式见 [native-host/README.md](./native-host/README.md)。
+
+## 典型工作流
+
+### 从真实页面生成明文网关
+
+1. 打开目标页面，在扩展中选择对应标签页；
+2. 进入“网络活动”，在“录制”中开始一次操作；
+3. 回到目标页面，完成一次登录、查询、提交或解密操作；
+4. 停止录制，查看按时间排序的业务 Trace 与自动推断 Profile；
+5. 证据充分时直接生成明文网关；证据不足时按提示进入“深度捕获”，再执行一次最小业务动作；
+6. 在“明文网关”查看数据流、页面函数、字段映射和本地回放结果；
+7. 保存后创建或复用浏览器共享会话；
+8. 在 Yakit Web Fuzzer 选择对应的浏览器明文网关，编辑明文并发送。
+
+页面刷新或跨文档导航后，依赖旧页面闭包的 Callable 可能失效。扩展会保留录制证据，但不会把旧函数静默绑定到新文档。
+
+### 进行双身份授权测试
+
+1. 准备两个已经登录不同账号、且认证上下文真正隔离的页面；
+2. 在“授权测试”中分别选择身份 A 与身份 B；
+3. 执行身份校验并开始双方请求捕获；
+4. 在两个页面分别完成同类业务动作；
+5. 让扩展自动选择正常基线，或手动确认请求；
+6. 选择资源字段或权限动作，审阅确定性测试计划；
+7. 确认请求预算与潜在副作用后执行；
+8. 查看四项矩阵、报文、结构化差异和业务归属证据；
+9. 将短时证据包交给 Yakit / AI Agent 做独立复核。
+
+同一浏览器普通窗口中的两个标签页通常共享 Cookie，不能仅凭“两个 Tab”证明身份隔离。Chromium 推荐使用普通窗口与无痕窗口，Firefox 可使用受支持的隔离上下文。
+
+### 让 Agent 使用登录后的页面
+
+1. 在“引擎连接”中勾选需要共享的 Tab 与 Frame；
+2. 选择只读或控制权限预设，并设置 15 分钟至 4 小时的有效期；
+3. 如确有必要，单独开启程序级 Eval；
+4. 创建浏览器共享会话；
+5. 在 Yakit 或 Yak AI Agent 中选择对应设备执行任务；
+6. 随时在扩展中暂停、恢复或撤销会话。
+
+## 构建与验证
+
+### 常用命令
+
+| 命令 | 用途 |
+| --- | --- |
+| `pnpm dev` | 启动 Chromium 开发模式。 |
+| `pnpm dev:wsl` | 使用持久 Profile 启动 WSL 开发环境。 |
+| `pnpm dev:firefox` | 启动 Firefox 开发模式。 |
+| `pnpm compile` | 运行 TypeScript 类型检查，不生成文件。 |
+| `pnpm test` | 运行 Vitest 测试。 |
+| `pnpm build:store` | 构建 Chrome Store 包。 |
+| `pnpm build:enterprise` | 构建本地或企业受管部署包。 |
+| `pnpm build:firefox` | 构建 Firefox MV2 包。 |
+| `pnpm build:firefox:amo` | 构建 Firefox MV3 AMO 包。 |
+| `pnpm verify:production` | 运行测试、类型检查、多目标构建和生产策略审计。 |
+| `pnpm verify:ui:store` | 验证 Chrome Store 运行路径。 |
+| `pnpm verify:ui:enterprise` | 验证 Enterprise User Scripts 路径。 |
+| `pnpm verify:ui:enterprise:fallback` | 验证 Enterprise 注入回退路径。 |
+| `pnpm verify:native` | 验证 Native Messaging Host 与 Bridge 链路。 |
+
+`verify:production` 会连续执行测试、类型检查和多个浏览器目标构建，资源占用明显高于单项命令。日常开发建议先运行与改动相关的测试和 `pnpm compile`，发布前再执行完整验证。
+
+### 构建差异
+
+| 构建 | 页面执行通道 | 适用场景 |
+| --- | --- | --- |
+| Chrome Store | User Scripts MAIN，不包含直接 Eval 注入回退 | 商店策略兼容分发。 |
+| Chrome Enterprise | User Scripts MAIN，并提供受控的打包回退通道 | 本地安装、企业受管与高级测试。 |
+| Firefox MV2 | Firefox 页面注入通道 | 本地与企业 Firefox 环境。 |
+| Firefox MV3 AMO | Invoke-only 公共分发包 | Firefox AMO 策略兼容分发。 |
+
+Chrome Store 构建声明 Chrome 138+。用户需要在扩展详情页开启“允许用户脚本”，页面主世界能力才能正常工作；未开启时扩展会明确报告原因，不会静默降级为直接 Eval。
+
+### 发布与下载
+
+发布由 GitHub Actions 的 **Build and Release** workflow（手动触发）完成：执行 `verify:production` 全量校验后，将四个变体打包为不可变的版本化产物上传到 OSS，再发布机器可读的 manifest，并从公网侧回读验证。CI 在每次 push / PR 时运行同一套构建与审计。
+
+**下载入口**（不要硬编码版本号）：
+
+```
+https://aliyun-oss.yaklang.com/chrome-extension/manifest.json
+```
+
+manifest 的 `latest` 指向最新版本，`versions[0]` 为完整记录，最多保留 10 个历史版本。每个版本按 `variant`（`chrome-store` / `chrome-enterprise` / `firefox` / `firefox-amo`）匹配 artifact，字段包括 `url`、`filename`、`sha256`、`size` 与 `checksum_url`；manifest 自身的 SHA-256 在同目录的 `manifest.json.sha256.txt`。
+
+推荐的消费流程：
+
+1. 拉取 `manifest.json`（缓存 5 分钟），按需选择版本与变体；
+2. 下载 artifact（版本化 URL 永不变更，缓存一年）到临时文件；
+3. 校验 `size` 与 `sha256`（或对比 `checksum_url` 内容）后，解压并安装；
+4. 变体用途见上表“构建差异”。
+
+**发布契约**：
+
+- 版本化产物不可变：URL 形如 `…/chrome-extension/<version>/<variant>-<version>.zip`，重复发布同版本时内容一致则跳过、不一致则流水线报错拒绝覆盖；
+- `manifest.json` 可变、缓存 5 分钟，先发布 manifest 再发布其校验文件，消费方可用校验文件识别中间态；
+- 发布 job 结束前有独立的 verify job 从公网下载全部产物，复核 sha256、缓存头与 zip 内 `manifest.json` 版本。
+
+## 权限与数据边界
+
+扩展声明 `tabs`、`scripting`、`cookies`、`proxy`、`webRequest`、`webNavigation`、`debugger` 等权限，是为了在用户主动选择的目标页面上提供对应安全测试能力。`nativeMessaging` 是可选权限，仅在用户选择 Native 模式时请求。
+
+默认数据策略：
+
+- Cookie、Storage、表单值、请求 Header / Body 和录制值预览分别受独立 Scope 控制；
+- 敏感网络字段与录制短时样本默认关闭或仅在当前会话保留；
+- 页面上下文采用有界结构化快照，不导出完整页面 HTML；
+- Deep Capture 可以保留页面内对象引用，但不会主动导出不可提取密钥；
+- 操作审计与诊断导出不包含 URL 参数值、Cookie、载荷、Eval 代码、调用参数或结果；
+- 远程订阅、代理配置和浏览器状态保存在扩展本地存储或 IndexedDB；
+- 撤销 Grant、关闭目标文档或断开设备会终止相关远程能力。
+
+更完整的 Capability、Grant、Bridge、Native Messaging、网络捕获、Recorder、Deep Capture 和 Transform Gateway 设计见 [ARCHITECTURE.md](./ARCHITECTURE.md)。视觉与交互规范见 [DESIGN.md](./DESIGN.md)。
+
+## 浏览器支持与已知边界
+
+- Chromium 系浏览器提供完整 Deep Capture 调试能力；Firefox 不提供完全相同的 Debugger 协议能力；
+- Store、Enterprise、Firefox MV2 与 Firefox AMO 构建的页面执行通道和权限不同；
+- 页面导航可能使文档绑定节点、Grant、Callable 和 Transform Profile 失效，扩展不会跨文档静默复用高权限引用；
+- 前端代码严重混淆、动态加载、原生模块、远程证明或服务端参与的算法不保证全自动还原；
+- 自动推断只在证据满足约束时生成 Profile，必要时仍需要测试者选择业务函数、确认字段语义或使用 AI 分析；
+- User-Agent 修改不等于完整设备指纹伪装；
+- 浏览器会话能够复用登录态，但不能替代目标授权、业务理解和测试人员的最终判断。

+
+## 负责任地使用
+
+浏览器真实上下文能够显著降低复杂登录态、前端加密和授权测试的操作成本，也意味着错误操作可能读取敏感数据、发送真实请求或改变业务状态。请在执行前确认目标范围、账号权限、请求预算和副作用，并保留必要的人工复核。
+
+Yakit Browser Agent 的目标不是替用户隐藏风险，而是把风险、证据、权限和执行现场放在同一个可理解、可控制的工作流中。

+# Yakit Browser Agent Native Host
+
+The Native Host is a small stdio-to-loopback-WebSocket transport. It does not store pairing credentials and does not execute browser commands itself. It forwards the normal Bridge v3 server challenge and extension authentication messages; Yak validates the origin-bound paired device signature and returns the engine identity, engine instance, connection, session, task, grant, protocol, and capability identity.
+
+Build from the Yak repository:
+
+```bash
+go build -o yakit-browser-agent-host ./common/browser/nativehostcmd
+```
+
+Install for Linux or macOS, using the ID shown by `chrome://extensions` for an unpacked build:
+
+```bash
+./native-host/install.sh \
+  --host-binary /absolute/path/to/yakit-browser-agent-host \
+  --extension-id YOUR_CHROME_EXTENSION_ID
+```
+
+On Windows, run PowerShell without administrator privileges:
+
+```powershell
+.\native-host\install.ps1 -HostBinary C:\path\yakit-browser-agent-host.exe -ExtensionId YOUR_CHROME_EXTENSION_ID
+```
+
+The installer registers Chrome, Chromium, Edge, Brave, and Firefox per-user locations. Chrome supplies its extension origin to the host. Firefox supplies the Native Host manifest path and add-on ID; the host verifies that ID against `allowed_extensions` before deriving its Bridge origin. It writes only the loopback endpoint to the user configuration directory. Run with `--uninstall` on POSIX or `-Uninstall` on Windows to remove the registrations; uninstall does not require an extension ID. When Chrome runs on Windows and development runs in WSL, build/install the Windows host with `install.ps1`; a Linux Native Host cannot be launched by Windows Chrome.
