 *   **Cookies:** The `httpx.Client` (used internally) handles cookies automatically, which are essential for maintaining a YouTube session.
 *   **Continuation Token:** A complex, encoded parameter generated using a custom Protocol Buffers-like encoding and various timestamps. This token is extracted from the `metadata` of the previous response.
 *   **Channel ID Discovery:** Performs lightweight scraping of YouTube's `embed` or `m.youtube.com` pages to extract the `channelId` using regular expressions.
-*   **Polling Interval:** Uses the `timeoutMs` from the response metadata to determine the next polling interval.
 
 **Implications (Reconfirmed):**
 *   **Fragility:** The reliance on dynamically generated `clientVersion`, extracted `visitorData`, regex-based scraping for `channelId`, and the undocumented internal API structure makes `pytchat` highly susceptible to breaking if YouTube changes its web client or internal API structure.

 2.  **`pytchat` Internal Mechanism Analysis:**
     *   **Action:** Investigate how `pytchat` manages session/authentication internally (e.g., does it require a logged-in browser session, or does it generate necessary headers?).
     *   **Action:** Understand how `pytchat` handles the `continuation` token and polling.
-    *   **Status:** **COMPLETED.** Analysis of `pytchat` source code (`api.py`, `core/__init__.py`, `core/pytchat.py`, `config/__init__.py`, `paramgen/liveparam.py`, `paramgen/enc.py`, `util/__init__.py`, `parser/live.py`) has provided a comprehensive understanding of its internal mechanisms.
