Pages bridgic creates via `_new_page()` are owned unconditionally. *Whether `opener()` returns a parent depends on Chromium's navigation disposition, not on who clicked: foreground-tab navigations (programmatic click, user plain left-click, `window.open()` with user gesture) preserve `openerId`; background-tab navigations (Cmd/Ctrl+click, middle-click, Cmd+T, address bar) clear it at the browser-process level. `rel="noopener"` only suppresses JS-level `window.opener` and does NOT prevent adoption. bridgic itself can bypass adoption by holding `Meta` via `key-down` before click (CDP `Input.dispatchMouseEvent.modifiers` propagates the held key) — role-agnostic, behavior-driven. Full matrix in [`docs/INTERNALS.md#adoption-truth-table-cdp-borrowed-mode`](docs/INTERNALS.md#adoption-truth-table-cdp-borrowed-mode).* +- **Popup follow**: when `auto_follow_popups=True` (default) and the popup's opener is `self._page`, `self._page` moves to the popup (mirrors Chrome's "new tab takes foreground" UX). Disable by passing `auto_follow_popups=False` to the constructor or via the same key in the config file. +- **Close fallback**: `_close_page` resolves a successor via `_select_fallback_page` in four tiers — `closed_page.opener()` → `_focus_stack` top — `get_pages()[0]` → `None`. `closed_page.opener()` is queried *before* `page.close()` is awaited so the opener relationship is still resolvable. -`StealthConfig` (default enabled) applies Chrome arguments and a JS init script to evade bot detection.

See [empirically-tried alternatives](#empirically-tried-alternatives-for-cdp-borrowed-downloads) below. | -Key distinction: -- `Browser._headless` — **user's intent** (hide the window?) -- `options["headless"]` passed to Playwright — **binary selection** (which binary to pick?) +#### Effective download path -`StealthArgsBuilder.build_args(headless_intent=True, locale=None)`: -- `headless_intent=True` (default, headless mode): uses `CHROME_STEALTH_ARGS` (50+ flags) + `CHROME_DISABLED_COMPONENTS` (28 features). Injects `--headless=new`, `--hide-scrollbars`, `--mute-audio`, and `--blink-settings=...` explicitly (Playwright normally adds these when `headless=True`, but since we pass `headless=False`, we add them manually). -- `headless_intent=False` (headed mode): uses `CHROME_STEALTH_ARGS_HEADED` (~11 flags) + `CHROME_DISABLED_COMPONENTS_HEADED` (3 features). Uses `--lang={locale}` (not hardcoded `en-US`). Never adds `--headless=new`. Goal: fingerprint indistinguishable from a real Chrome user — excessive disable-* flags in headed mode create a detectable anomaly and can break Cloudflare Turnstile's AJAX challenge requests. +`Browser._effective_cdp_downloads_path(client_cwd=None)` resolves the path in CDP-borrowed mode: -This redirect is skipped when: -- `StealthConfig.use_new_headless=False` (opt-out to restore old headless-shell) -- System Chrome is used (`channel` or `executable_path` set) — system Chrome manages its own binary +1. Explicit `Browser(downloads_path=...)` constructor arg or `bridgic-browser.json` config — always wins. +2. `client_cwd` (per-command) or `self._pending_client_cwd` (set by the daemon before `_start()`). The CLI client puts `os.getcwd()` in every socket request; the daemon sets the hint pre-dispatch so the first lazy-start L1 sees it too. Gives `bridgic-browser` `curl -O`-style ergonomics — files land where the user ran the command. +3. `~/Downloads` fallback. -**Headed mode auto-switches to system Chrome**: -Playwright's bundled "Google Chrome for Testing" binary is blocked by Google OAuth (login rejected as "unsafe browser") and shows a "test" label in the macOS Dock. In headed mode, when stealth is enabled and system Chrome is detected (`_detect_system_chrome()`), bridgic automatically sets `channel="chrome"` to use the real system Chrome binary. This is transparent to the user. The headed stealth args (~11 flags) are still applied; `--test-type=` is added to suppress Chrome's "unsupported flag" warning banner for `--disable-blink-features=AutomationControlled`. If system Chrome is not installed, bridgic falls back to Chrome for Testing. +In non-CDP / CDP-owned modes the path is `self._downloads_path` only (CWD plumbing doesn't apply because DownloadManager is the pipeline). The CLI daemon **skips** its auto-default `downloads_path=~/Downloads` when `BRIDGIC_CDP` is set — otherwise that default would be indistinguishable from a user-explicit value and silently win over the CWD priority above. -**JS init script** (`_STEALTH_INIT_SCRIPT_TEMPLATE` in `_stealth.py`) — **headless mode only**. Skipped entirely in headed mode (`self._headless=False`) because `context.add_init_script()` runs in ALL frames including Cloudflare Turnstile's challenge iframe; patching `window.chrome` (`configurable:false`), `navigator.permissions.query`, and WebGL prototype inside the iframe causes detectable API inconsistencies that fail the challenge. Playwright CLI injects nothing and passes Turnstile; bridgic matches that behaviour in headed mode. +#### CDP-borrowed flow detail -When active (headless mode), patches these navigator/window properties before any page script runs: +**L1 (post-connect, `_set_cdp_download_behavior` with `session=`)**: after creating bridgic's tab, send `Browser.setDownloadBehavior(allowAndName, downloadPath=, eventsEnabled=true)` via `self._cdp_download_session = await self._context.new_cdp_session(self._page)`. Same session attaches `CdpDownloadRenamer`. Only runs in CDP-borrowed mode (`not self._cdp_context_owned`). -**Anti-toString-detection (`_mkNative` framework)**: -All patched functions are registered in a `WeakSet` (`_nativeFns`) via `_mkNative(fn, name)`. `Function.prototype.toString` is itself intercepted to return `"function foo() { [native code] }"` for any registered function. This closes the entire class of "call `.toString()` on a function to detect monkey-patching" attacks used by DataDome, PerimeterX, and Cloudflare bot detectors. +**Per-command `cwd-update` (`update_cdp_downloads_path`)**: re-sends the same command (still via the page session) when the daemon's `client_cwd` resolves to a different effective path than `self._current_cdp_download_path`.

The defense covers downloads from the user's other tabs that Playwright captured into its tempdir (per-context override on the borrowed default context still routes there); skips trace/video/HAR artifacts and files DownloadManager already saved. Mostly a no-op now that bridgic's own tab uses page-session routing, but kept as defense in depth. -**Patched properties**: -- `navigator.webdriver` → **conditionally** `undefined`; checks `Object.getOwnPropertyDescriptor(Navigator.prototype, 'webdriver')` first and patches the prototype descriptor. Falls back to instance property only if the prototype has no descriptor but the value is non-undefined. Avoids creating an own-property (which makes `'webdriver' in navigator` = true — detectable in real Chrome where the property is absent). -- `navigator.plugins` / `navigator.mimeTypes` → realistic PDF Viewer entries (5 plugins, 2 MIME types); each plugin holds its own per-plugin mime copies so `enabledPlugin` refs are correct -- `navigator.languages` → derived from `Browser(locale=...)` to keep `navigator.language === navigator.languages[0]` (e.g. `["zh-CN", "zh", "en"]` for `locale="zh-CN"`); defaults to `["en-US", "en"]` -- `window.chrome` → complete object with `runtime`, `csi()`, `loadTimes()` (all wrapped with `_mkNative`) -- `navigator.permissions.query` → returns `"default"` for notifications (not `"denied"`); wrapped with `_mkNative` -- `window.outerWidth/Height` → matches `innerWidth/Height` when zero (guard for edge cases; with `--headless=new` + `screen` context option these are already correctly set by Chrome) -- `navigator.deviceMemory` → `8` (headless environments may return `undefined`) -- `navigator.hardwareConcurrency` → `8` when value is 0 or 1 (headless may report fewer cores) -- `navigator.connection` → `{ effectiveType: '4g', downlink: 10, rtt: 100, saveData: false }` when absent -- `WebGLRenderingContext` / `WebGL2RenderingContext` → `getParameter(37445/37446)` **conditionally** returns `'Intel Inc.'` / `'Intel Iris OpenGL Engine'` only when the real vendor contains `'Google'` or `'SwiftShader'` (masks SwiftShader which is a well-known bot signal). On headed Apple Silicon Mac the real `'Apple Inc.'` value is preserved so the WebGL fingerprint stays consistent with DPI, Canvas, and font rendering signals. `getParameter` is wrapped with `_mkNative`. -- `document.hasFocus()` → always returns `true` (headless tabs return `false` by default; Cloudflare and DataDome probe this); wrapped with `_mkNative` -- `document.hidden` → always `false` (via `Object.defineProperty`) -- `document.visibilityState` → always `'visible'` (via `Object.defineProperty`); headless tabs default to `'hidden'` which is a strong bot signal -- `Notification.permission` → guarded: only patched if `Notification` exists and its permission is `'denied'`; returns `'default'` - -`get_init_script(locale=None)` accepts the locale and performs the `__BRIDGIC_LANGS__` substitution before returning the script.

Chrome reverts to its native prefs for any post-disconnect downloads on the user's tabs. -### CLI architecture +#### Filename preservation (CdpDownloadRenamer) -The `bridgic-browser` CLI uses a **daemon + Unix socket** pattern so the Playwright `Browser` instance persists across multiple short-lived CLI invocations. +`allowAndName` writes files as `/` (e.g. `08d0c134-9231-478e-aca1-08b3e0ec1798`). `_cdp_download_renamer.py:CdpDownloadRenamer`: -``` -bridgic-browser click @8d4b03a9 - │ - ▼ - _client.py Unix socket _daemon.py - send_command("click",...) ~/.bridgic/bridgic-browser/run/bridgic-browser.sock asyncio server - │──── JSON request ─────────────────────────────► + Browser instance - │◄─── JSON response ──────────────────────────── dispatch → tool fn() -``` - -Key implementation details: -- **`_client.py`**: `send_command()` auto-starts the daemon if no socket exists. `_spawn_daemon()` uses `select.select()` + `os.read()` for the 30-second ready timeout (avoids blocking `proc.stdout.read()`). `start_if_needed=False` prevents auto-start for the `close` command. -- **`_daemon.py`**: `run_daemon()` creates a `Browser()` instance directly (lazy start — Playwright does **not** launch immediately; `Browser.__init__` auto-loads config from `_config.py`), writes `BRIDGIC_DAEMON_READY` to stdout, and serves one JSON command per connection. The browser's Playwright process starts on the first command that calls `_ensure_started()` (e.g. `navigate_to`). `asyncio.wait_for(reader.readline(), timeout=60)` prevents hanging on idle connections. Signal handling uses `loop.add_signal_handler()` (asyncio-safe). -- **`_commands.py`**: 67 Click commands in 15 sections via `SectionedGroup`. `scroll` uses `--dy`/`--dx` options (not positional) to support negative values. `screenshot`/`pdf`/`upload`/`storage-save`/`storage-load`/`trace-stop` call `os.path.abspath()` on the client side before sending (daemon cwd may differ). `snapshot` supports `-i`/`--interactive`, `-f/-F`/`--full-page/--no-full-page`, `-l`/`--limit` (default 10000), and `-s`/`--file` (overflow file path); it delegates to `browser.get_snapshot_text()`. When content exceeds limit or `--file` is provided, full snapshot is saved to a file (auto-generated under `~/.bridgic/bridgic-browser/snapshot/` when over limit, or the specified path). - - **`wait`**: argument is named `SECONDS_OR_TEXT`. When the argument parses as a float it always takes the time-wait path (`wait_seconds`); when it is a string it takes the text-wait path (`text` or `text_gone` with `--gone`). The `--gone` flag is **only** meaningful with a string argument — a numeric argument with `--gone` is ignored (number always → time). Unit is **seconds**, not milliseconds. This is documented explicitly in the command docstring and in `_cli_catalog.py` to prevent LLM confusion. Text search traverses **all frames** (main + iframes) via polling, so text inside iframes is detectable. - - **`type`**: docstring explicitly states the text goes into the **currently focused element** and that the user must `click` or `focus` the target first. - - **`mouse-move` / `mouse-click` / `mouse-drag`**: coordinates are **viewport pixels from the top-left corner**; documented in both docstrings and `_cli_catalog.py`. - - **`eval-on`**: CODE must be an arrow function or named function that receives the element as its argument (e.g. `"(el) => el.textContent"`); this calling convention is documented in the docstring with examples. -- **Config loading**: `Browser.__init__` auto-loads config via `_config.py:_load_config_sources()`. The `--headed` CLI flag merges `{"headless": false}` into `BRIDGIC_BROWSER_JSON` before spawning the daemon. The `--clear-user-data` CLI flag merges `{"clear_user_data": true}` into `BRIDGIC_BROWSER_JSON`. -- **`close` command fast-path**: the daemon calls `browser.inspect_pending_close_artifacts()` to pre-allocate a session dir, trace path, and video paths (all grouped under `~/.bridgic/bridgic-browser/tmp/close--/`), responds to the client immediately with those paths, then sets `stop_event`. Actual `browser.close()` runs after the client disconnects. After close, `_write_close_report()` writes `close-report.json` in the session dir with status (`"success"`, `"success_with_timeouts"`, `"error"`, or `"timeout"`), artifact paths, and any errors. -- **Daemon cleanup ownership guard**: after `browser.close()` finishes, `run_daemon()` reads the run-info file and compares its `pid` field to `os.getpid()` before calling `transport.cleanup()` / `remove_run_info()`. This prevents the outgoing daemon from deleting the new daemon's socket when a `close` is followed immediately by a new command (which starts a new daemon before the old one's shutdown completes). If the run-info is gone (`None`) the old daemon is still the owner and cleans up normally. +1. On `Browser.downloadWillBegin`, records `{guid → (sanitized suggestedFilename, target_dir)}` — target dir snapshotted so a concurrent CWD swap doesn't retarget files mid-flight. +2. On `Browser.downloadProgress.state="completed"`, renames `/` → `/`. Conflicts resolve to `name (1).ext`, `name (2).ext` (Chrome's scheme). +3. On `state="canceled"`, removes the GUID stub. -Socket path: `BRIDGIC_SOCKET` env var (default `~/.bridgic/bridgic-browser/run/bridgic-browser.sock`). -The directory is created with `0o700` permissions on first use. Users upgrading from an older version that used `/tmp/bridgic-browser.sock` should stop any running daemon first (`bridgic-browser close`) before upgrading. +`sanitize_filename()` strips path separators, Windows-forbidden chars (`< > : " | ? *`), control bytes, and truncates to 255 bytes while preserving the extension. Empty result → `"download"`. -Snapshot overflow: `get_snapshot_text(limit=10000, file=None, ...)` — when content exceeds `limit` or `file` is explicitly provided, full snapshot is written to `file` (auto-generated if `None` and over limit) and only a notice with the file path is returned. `limit` must be ≥ 1. `file` is validated: empty/whitespace-only paths, null bytes, and existing directories raise `InvalidInputError`. +#### Empirically-tried alternatives for CDP-borrowed downloads -## Key Implementation Details & Playwright Internals +Verified against Chrome 138, macOS, with "Ask where to save each file" preference **on** (the default in many regions): -### Two Co-existing Ref Systems (Foundation for Understanding the Entire Chain) - -bridgic has **two distinct ref systems** that must not be confused: - -| | bridgic ref | playwright_ref | +| Attempt | Result | Verdict | |---|---|---| -| Example | `"8d4b03a9"` | `"e369"` / `"f1e5"` | -| Generated in | `_snapshot.py:_compute_stable_ref()` | Playwright injected script `computeAriaRef()` | -| Format | SHA-256(namespace+role+name+frame_path+nth) first 4 bytes hex | `{refPrefix}e{lastRef}` incrementing integer | -| Stability | **Stable across snapshots** (same element, same ref) | **Resets after each snapshot** (valid only within current snapshotForAI) | -| Purpose | Exposed to LLM / tool calls / CLI | O(1) DOM pointer lookup for aria-ref fast path | -| Stored in | `EnhancedSnapshot.refs: Dict[str, RefData]` | `RefData.playwright_ref` | - ---- - -### Playwright Source: Ref Generation Rules - -All source paths are under `.venv/lib/python3.10/site-packages/playwright/driver/package/lib/`. - -#### 1. `lastRef` Counter and `computeAriaRef()` -**File**: `generated/injectedScriptSource.js` (this script is injected into each frame; each frame has its own independent instance) - -```javascript -// injectedScriptSource.js — module-level variable in injected script (independent per frame) -var lastRef = 0; - -function computeAriaRef(ariaNode, options) { - if (options.refs === "none") return; - // when mode="ai", refs="interactable" — only assigns refs to visible elements that receive pointer events - if (options.refs === "interactable" && (!ariaNode.box.visible || !ariaNode.receivesPointerEvents)) - return; - - let ariaRef = ariaNode.element._ariaRef; // cache on the DOM element - if (!ariaRef || ariaRef.role !== ariaNode.role || ariaRef.name !== ariaNode.name) { - // cache miss (first time / role or name changed) → generate new ref - ariaRef = { - role: ariaNode.role, - name: ariaNode.name, - ref: (options.refPrefix ??

However, `locator.evaluate()`'s JS execution context is **not affected** — it always runs in the frame that **owns the locator's scope** (see below). +#### Caveats ---- +- **bridgic's tab gets the override; user's tabs keep their normal Chrome UX** (intentional — the page-session scope is bridgic's tab only). User-initiated downloads in their other tabs still go to their Chrome's configured directory and obey their "Ask where to save" pref. This is by design and matches the "I gave you full control of *my agent's* tab via `--cdp`" semantics — user's private workspace is untouched. +- **DownloadManager is not attached in CDP-borrowed mode.** Chrome writes directly to the final path; Playwright's per-context `download` event doesn't fire when the file is routed away from `artifactsDir`. `wait_for_download()` is correspondingly **unsupported in CDP-borrowed mode** — use CDP-owned or non-CDP for that. +- **The renamer is best-effort.** If a CDP event is missed or the OS rename fails (cross-FS, permission, etc.) the file stays at its GUID path with a warning logged. It never deletes content. +- **`last_close_artifacts()`** exposes a `rescued_downloads` list when L2 actually moved anything. +- **"Show in Folder"** in Chrome's download bubble is broken whenever `setDownloadBehavior(allowAndName, eventsEnabled=true)` is active. This is a Chromium bug (`#324282051`) affecting all CDP-using tools. See [docs/KNOWN_LIMITATIONS.md](docs/KNOWN_LIMITATIONS.md). -### bridgic Source: Ref Generation Rules - -#### 7.

The coordinate systems differ, so `elementFromPoint` finds the wrong element (typically the child iframe node), triggering a false "covered" report. After skipping, `locator.click()` lets Playwright handle coordinate transformation internally. +1. Does the patch live in `_STEALTH_INIT_SCRIPT_TEMPLATE` (runs in all frames)? If yes, ask: would patching this in a cross-origin Cloudflare iframe create an inconsistency vs. what Cloudflare's server logged for the parent page request? +2. Does the patch use a CDP override (`Emulation.*`, `Network.*`, `Page.*`)? CDP overrides apply to the whole target including all its frames. Gate to `self._headless` unless you've verified iframe consistency. +3. Does the patch hook `page.on('worker')` / `context.on('serviceworker')`? Workers can be spawned by any frame in the page tree — same rule. +4. Does the patch wrap a global constructor like `Worker`, `WebSocket`, `RTCPeerConnection`? Wrap inside `if (window === window.top) { ... }` if the wrap result is observably different from the original. +5. Run the 3-site headed verification (`bash scripts/qa/...` or manual): a Cloudflare-Turnstile-protected page (Cloudflare), `https://x.com` (server-side detection), `https://blog.aepkill.com/demos/devtools-detector/` (devtools probe).

All paths chain `frame_locator("iframe").nth(n)` per `frame_path` level for iframe support. -Impact on `get_snapshot(interactive=True)`: a small icon with only a CSS class (no `data-action`, no `aria-label`, no `cursor:pointer`) will **not** appear in the interactive snapshot. If an icon is missing, add `data-action` or `aria-label` to the element. +Key constraints: +- `frame_path` (per-level local indices) is unrelated to Playwright's `frame.seq` (page-level global counter). +- **Covered-element check** uses `window.parent !== window` (not `window.frameElement !== null`) to detect iframes — the latter returns `null` under `file://` protocol. Iframe elements skip the check entirely because `bounding_box()` returns main-viewport coordinates while `elementFromPoint()` uses iframe-local coordinates. +- **Small icon rule**: icons 10–50 px are interactive only with `data-action` or `aria-label` (not `classAndId` — too many false positives). ---- +For complete source-level documentation of Playwright internals, ref generation, lookup strategies, and iframe handling, see [`docs/INTERNALS.md`](docs/INTERNALS.md). -### Debug Logging +## Debug Logging ```bash BRIDGIC_LOG_LEVEL=DEBUG bridgic-browser snapshot -i @@ -526,14 +260,9 @@ BRIDGIC_LOG_LEVEL=DEBUG bridgic-browser click ``` Key DEBUG log points (`_browser.py`): -- `[get_element_by_ref] aria-ref fast-path hit: ref=... playwright_ref=... frame_path=...` -- `[get_element_by_ref] aria-ref stale (count=N), falling through to CSS: ...` -- `[get_element_by_ref] aria-ref exception (...), falling through to CSS: ...` -- `[get_element_by_ref] CSS path: ref=... role=... name=... nth=... frame_path=...` -- `[click_element_by_ref] covered at (x, y), clicking intercepting element` -- `_click_checkable_target: covered at (x, y), clicking intercepting element` - ---- +- `[get_element_by_ref] aria-ref fast-path hit/stale/exception` — ref lookup phase transitions +- `[get_element_by_ref] CSS path: ref=... role=... name=... nth=... frame_path=...` — fallback strategy +- `[click_element_by_ref] covered at (x, y), clicking intercepting element` — covered-element redirect ## Testing notes diff --git a/README.md b/README.md index 3410228..9ede40f 100644 --- a/README.md +++ b/README.md @@ -12,8 +12,8 @@ - **Python-based Tools** - Used for agent / workflow code generation; Easier integration with [Bridgic](https://github.com/bitsky-tech/bridgic) - **Snapshot with Semantic Invariance** - A representation of page snapshot based on accessibility tree and a specially designed ref-generation algorithm that ensures element refs remain unchanged across page reloads - **Skills** - Used for guided exploration and code generation; Compatible with most of coding agents -- **Stealth Mode (Enabled by Default)** - Mode-aware anti-detection: 50+ Chrome args + JS patches in headless mode; minimal ~11 flags in headed mode to match real Chrome fingerprint -- **Persistent & Ephemeral Sessions** - Persistent profile by default (`~/.bridgic/bridgic-browser/user_data/`); pass `clear_user_data=True` for an ephemeral session with no profile +- **Stealth Mode (Enabled by Default)** - Mode-aware anti-detection covering 24+ JS/CDP fingerprint vectors.

The whole point of these three steps is to delegate + parsing to V8 itself. An AST pre-pass in Python would (a) duplicate work + V8 already does correctly, (b) introduce a second source of truth that + can drift from V8's spec, and (c) add a parser dependency.

Workaround: have the + user's expression ``JSON.stringify`` an explicit shape, or convert + to a JSON-safe form before returning. + * **Built-in collections** (``Map``, ``Set``, ``NodeList``, etc.) + serialize to ``{}`` because their entries live behind iterators, + not enumerable properties. Workaround: ``Array.from(...).map(...)``. + + Everything that *is* JSON-safe round-trips with byte-identical parity to + Playwright — verified end-to-end against real Chrome ``Runtime.evaluate`` + in the integration suite.

This is the configuration validated on +2026-04-21; any command regression here is a real regression. + +### V2 — Persistent × Headed × Stealth=on +- In headed mode the stealth JS init script is skipped (see the Stealth section + of `CLAUDE.md`), so `verify-*` commands that depend on animation/render + timing can be flaky: + - `wait_text` / `wait_gone` (depend on the `Show Text Later` animation) + - `verify-visible` assertions can time out under slow rendering +- `search` depends on the live search engine; headed mode can also surface + consent banners / popups that affect success rate. + +### V3 — Ephemeral × Headless × Stealth=on +- `storage-load`: the `storage-state.json` has just been produced by the + preceding `storage-save` and should replay successfully. However, in + ephemeral mode every `launch()` creates a brand-new context, so if + `storage-load` is called before a `navigate_to` (which is the current script + order) its effect may be limited. +- `cookies-domain` filter: under ephemeral mode `example.com` cookies may not + exist; the command should still return an empty list rather than error. + +### V4 — Ephemeral × Headed × Stealth=on +Inherits all risks from V2 and V3. Headed + ephemeral is the combination +closest to how an end user actually uses the tool. + +### V5 — CDP × Headless × Stealth=on +**Expected N/A commands** (CDP-borrowed-context limitations): +- `video-start` / `video-stop`: in a borrowed CDP context `start_video` + spins up its own CDP screencast session, which can conflict with the + DevTools session held by the external Chrome — needs human review. +- `storage-save` / `storage-load`: in borrowed mode these go through the + DOMStorage CDP protocol; if the origin has no active frame Playwright + raises `Frame not found`. +- `close`: in CDP mode this only detaches; it does not kill the external + Chrome. The CLI command itself should still return 0 and be PASS. +- The inline `open --cdp` smoke is auto-marked `N/A (already covered by variant V5)`. + +**Expected behavioral differences**: +- Stealth launch args cannot be applied to an already-running Chrome; only + the JS init script gets injected. +- `navigate_to --wait-for networkidle` may be slower than in persistent mode + because the external Chrome has unrelated background traffic. + +### V6 — CDP × Headed × Stealth=on +Inherits every risk from both V5 and V2. It is the most fragile combination; +its main purpose is to cover the "user already has Chrome open, let the agent +take it over" usage scenario. + +### V7 — Persistent × Headless × Stealth=off (smoke) +Runs only 8 core commands: `open → info → snapshot -i → reload → eval → +screenshot → verify-title → close`. +- Purpose: quickly verify that the `{"stealth": false}` code path does not + crash. +- Expected: **all PASS**. A FAIL here means the stealth-off path has a real + bug — priority L0. + +--- + +## Known cross-variant systemic risks (from `cr_pr21_cdp_url_findings.md`) + +Watch these closely in any CDP-related variant (V5/V6): + +1. **Scattered timeout constants**: `navigate_to`, `close`, `start_video`, + etc. each hardcode their own timeout. If a command FAILs under V5/V6, + check the log for a "timeout" exception. +2. **Post-CDP-reconnect latency**: prior CRs repeatedly hit "reconnect + succeeded but the first subsequent command hangs". Review V5/V6 logs for + any command taking unusually long (>15 s). +3. **Snapshot prefetch pollution**: under V3/V5 if the refs returned by + `snapshot` do not match the current page, the usual cause is that the + ephemeral/CDP prefetch logic failed to notice a page reload. + +## Known limitations (must be surfaced in the report) + +- **Headed variants require a macOS GUI**: on a headless CI they are skipped + wholesale. +- **CDP variants depend on `QA_CHROME_BIN`**: if the system Chrome cannot be + found the whole variant is skipped. +- **Network-dependent commands** (`search`, `wait-network`, + `open_for_network`, …) are affected by network flakiness; a sporadic FAIL + is not necessarily a regression and needs log-based human judgment. +- **`video-start` / `video-stop`** require ffmpeg; when `which ffmpeg` is + empty these commands will FAIL. +- **`get_element_by_prompt`** requires `OPENAI_API_KEY + OpenAILlm`; the SDK + differential pass marks it N/A explicitly. +

The trigger path matters: + - ✅ **Adopted**: bridgic-initiated click, programmatic `page.click()`, **user plain left-click** on `` or `window.open()`. `rel="noopener"` / `rel="noreferrer"` / `window.open(...,'noopener')` do not disable this — they suppress JS-level `window.opener` but not the CDP-level opener relationship. + - ❌ **Not adopted**: user **Cmd+click** (macOS) / **Ctrl+click** (Win/Linux) / **middle-click** on a link, or any tab the user opens via Cmd+T / address bar / history. Chromium severs the opener at the browser-process level for these "background tab" navigations, so the CDP `openerId` is genuinely empty and bridgic cannot see them. + +Only owned pages appear in `get_tabs` / `switch_tab` / `close_tab`. The user's pre-existing tabs — and any pop-ups they trigger via Cmd-click or open via Cmd+T / address bar — remain invisible to bridgic. This is a privacy boundary: it prevents the LLM / CLI from inadvertently switching to, reading, or closing the user's private work tabs. + +If you need to operate on a page the user already has open, navigate to it through bridgic instead (`bridgic-browser navigate-to ` or `new-tab `). bridgic cannot reach across into the user's existing tab. + +When `close()` runs (or the daemon shuts down), bridgic **only disconnects** — no tabs are closed. The remote Chrome continues running exactly as the user left it. + +The daemon log records which Chrome instance was joined and how many user tabs were preserved — useful with `--cdp auto` to confirm you attached to the expected browser: + +``` +[CDP] connected; created new bridgic tab (borrowed_context=True, preserved_existing_tabs=3) +``` + +### Popup-follow behavior + +By default, when a popup is spawned from `self._page` (the tab bridgic is currently driving), bridgic's active page automatically follows the popup — mirroring Chrome's UX where the just-spawned tab takes the foreground. To keep `self._page` fixed on the original tab, pass `auto_follow_popups=False` to the `Browser(...)` constructor (or the same key in your config file).
