fix(chat): conditional fade overlay and opacity for non-preferred panels

- Add preferredIdx !== -1 guard and responses.find() for safer lookups

 ## Full vs Lite Deployments
 
 Code changes must consider both regular Onyx deployments and Onyx lite deployments. Lite deployments disable the vector DB, Redis, model servers, and background workers by default, use PostgreSQL-backed cache/auth/file storage, and rely on the API server to handle background work. Do not assume those services are available unless the code path is explicitly limited to full deployments.

+## SWR Cache Keys — Always Use SWR_KEYS Registry
+
+All `useSWR()` calls and `mutate()` calls in the frontend must reference the centralized `SWR_KEYS` registry in `web/src/lib/swr-keys.ts` instead of inline endpoint strings or local string constants. Never write `useSWR("/api/some/endpoint", ...)` or `mutate("/api/some/endpoint")` — always use the corresponding `SWR_KEYS.someEndpoint` constant. If the endpoint does not yet exist in the registry, add it there first. This applies to all variants of an endpoint (e.g. query-string variants like `?get_editable=true` must also be registered as their own key).

-1. dev_setup.md (start here): gives you a guide to setting up a local development environment.
-2. contribution_process.md: how to ensure you are building valuable features that will get reviewed and merged.
-3. best_practices.md: before asking for reviews, ensure your changes meet the repo code quality standards.
+## Contribution Process
 
 To contribute, please follow the
 ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow.
 
+### 1. Get the feature or enhancement approved
+
+Create a GitHub issue and see if there are upvotes. If you feel the feature is sufficiently value-additive and you would like approval to contribute it to the repo, tag [Yuhong](https://github.com/yuhongsun96) to review.
+
+If you do not get a response within a week, feel free to email yuhong@onyx.app and include the issue in the message.
+
+Not all small features and enhancements will be accepted as there is a balance between feature richness and bloat. We strive to provide the best user experience possible so we have to be intentional about what we include in the app.
+
+### 2. Get the design approved
+
+The Onyx team will either provide a design doc and PRD for the feature or request one from you, the contributor. The scope and detail of the design will depend on the individual feature.
+
+### 3. IP attribution for EE contributions
+
+If you are contributing features to Onyx Enterprise Edition, you are required to sign the [IP Assignment Agreement](contributor_ip_assignment/EE_Contributor_IP_Assignment_Agreement.md).
+
+### 4. Review and testing
+
+Your features must pass all tests and all comments must be addressed prior to merging.
+
+### Implicit agreements
+
+If we approve an issue, we are promising you the following:
+- Your work will receive timely attention and we will put aside other important items to ensure you are not blocked.
+- You will receive necessary coaching on eng quality, system design, etc. to ensure the feature is completed well.
+- The Onyx team will pull resources and bandwidth from design, PM, and engineering to ensure that you have all the resources to build the feature to the quality required for merging.
+
+Because this is a large investment from our team, we ask that you:
+- Thoroughly read all the requirements of the design docs, engineering best practices, and try to minimize overhead for the Onyx team.
+- Complete the feature in a timely manner to reduce context switching and an ongoing resource pull from the Onyx team.
+
+---
+
+## Development Setup
+
+Onyx being a fully functional app, relies on some external software, specifically:
+
+- [Postgres](https://www.postgresql.org/) (Relational DB)
+- [OpenSearch](https://opensearch.org/) (Vector DB/Search Engine)
+- [Redis](https://redis.io/) (Cache)
+- [MinIO](https://min.io/) (File Store)
+- [Nginx](https://nginx.org/) (Not needed for development flows generally)
+
+> **Note:**
+> This guide provides instructions to build and run Onyx locally from source with Docker containers providing the above external software.
+> We believe this combination is easier for development purposes. If you prefer to use pre-built container images, see [Running in Docker](#running-in-docker) below.
+
+### Prerequisites
+
+- **Python 3.11** — If using a lower version, modifications will have to be made to the code. Higher versions may have library compatibility issues.
+- **Docker** — Required for running external services (Postgres, OpenSearch, Redis, MinIO).
+- **Node.js v22** — We recommend using [nvm](https://github.com/nvm-sh/nvm) to manage Node installations.
+
+### Backend: Python Requirements
+
+We use [uv](https://docs.astral.sh/uv/) and recommend creating a [virtual environment](https://docs.astral.sh/uv/pip/environments/#using-a-virtual-environment).
+
+```bash
+uv venv .venv --python 3.11
+source .venv/bin/activate
+```
+
+_For Windows, activate the virtual environment using Command Prompt:_
+
+```bash
+.venv\Scripts\activate
+```
+
+If using PowerShell, the command slightly differs:
+
+```powershell
+.venv\Scripts\Activate.ps1
+```
+
+Install the required Python dependencies:
+
+```bash
+uv sync --all-extras
+```
+
+Install Playwright for Python (headless browser required by the Web Connector):
+
+```bash
+uv run playwright install
+```
+
+### Frontend: Node Dependencies
+
+```bash
+nvm install 22 && nvm use 22
+node -v # verify your active version
+```
+
+Navigate to `onyx/web` and run:
+
+```bash
+npm i
+```
+
+### Formatting and Linting
+
+#### Backend
+
+Set up pre-commit hooks (black / reorder-python-imports):
+
+```bash
+uv run pre-commit install
+```
+
+We also use `mypy` for static type checking. Onyx is fully type-annotated, and we want to keep it that way! To run the mypy checks manually:
+
+```bash
+uv run mypy .  # from onyx/backend
+```
+
+#### Frontend
+
+We use `prettier` for formatting. The desired version will be installed via `npm i` from the `onyx/web` directory. To run the formatter:
+
+```bash
+npx prettier --write .  # from onyx/web
+```
+
+Pre-commit will also run prettier automatically on files you've recently touched. If re-formatted, your commit will fail. Re-stage your changes and commit again.
+
+---
+
+## Running the Application
+
+### VSCode Debugger (Recommended)
+
+We highly recommend using VSCode's debugger for development.
+
+#### Initial Setup
+
+1. Copy `.vscode/env_template.txt` to `.vscode/.env`
+2. Fill in the necessary environment variables in `.vscode/.env`
+
+#### Using the Debugger
+
+Before starting, make sure the Docker Daemon is running.
+
+1. Open the Debug view in VSCode (Cmd+Shift+D on macOS)
+2. From the dropdown at the top, select "Clear and Restart External Volumes and Containers" and press the green play button
+3. From the dropdown at the top, select "Run All Onyx Services" and press the green play button
+4. Navigate to http://localhost:3000 in your browser to start using the app
+5. Set breakpoints by clicking to the left of line numbers to help debug while the app is running
+6. Use the debug toolbar to step through code, inspect variables, etc.
+
+> **Note:** "Clear and Restart External Volumes and Containers" will reset your Postgres and OpenSearch (relational-db and index). Only run this if you are okay with wiping your data.
+
+**Features:**
+- Hot reload is enabled for the web server and API servers
+- Python debugging is configured with debugpy
+- Environment variables are loaded from `.vscode/.env`
+- Console output is organized in the integrated terminal with labeled tabs
+
+### Manually Running for Development
+
+#### Docker containers for external software
+
+You will need Docker installed to run these containers.
+
+Navigate to `onyx/deployment/docker_compose`, then start up Postgres/OpenSearch/Redis/MinIO with:
+
+```bash
+docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d index relational_db cache minio
+```
+
+(index refers to OpenSearch, relational_db refers to Postgres, and cache refers to Redis)
+
+#### Running Onyx locally
+
+To start the frontend, navigate to `onyx/web` and run:
+
+```bash
+npm run dev
+```
+
+Next, start the model server which runs the local NLP models. Navigate to `onyx/backend` and run:
+
+```bash
+uvicorn model_server.main:app --reload --port 9000
+```
+
+_For Windows (for compatibility with both PowerShell and Command Prompt):_
+
+```bash
+powershell -Command "uvicorn model_server.main:app --reload --port 9000"
+```
+
+The first time running Onyx, you will need to run the DB migrations for Postgres. After the first time, this is no longer required unless the DB models change.
+
+Navigate to `onyx/backend` and with the venv active, run:
+
+```bash
+alembic upgrade head
+```
+
+Next, start the task queue which orchestrates the background jobs. Still in `onyx/backend`, run:
+
+```bash
+python ./scripts/dev_run_background_jobs.py
+```
+
+To run the backend API server, navigate back to `onyx/backend` and run:
+
+```bash
+AUTH_TYPE=basic uvicorn onyx.main:app --reload --port 8080
+```
+
+_For Windows (for compatibility with both PowerShell and Command Prompt):_
+
+```bash
+powershell -Command "
+    $env:AUTH_TYPE='basic'
+    uvicorn onyx.main:app --reload --port 8080
+"
+```
+
+> **Note:** If you need finer logging, add the additional environment variable `LOG_LEVEL=DEBUG` to the relevant services.
+
+#### Wrapping up
+
+You should now have 4 servers running:
+
+- Web server
+- Backend API
+- Model server
+- Background jobs
+
+Now, visit http://localhost:3000 in your browser. You should see the Onyx onboarding wizard where you can connect your external LLM provider to Onyx.
+
+You've successfully set up a local Onyx instance!
+
+### Running in Docker
+
+You can run the full Onyx application stack from pre-built images including all external software dependencies.
+
+Navigate to `onyx/deployment/docker_compose` and run:
+
+```bash
+docker compose up -d
+```
+
+After Docker pulls and starts these containers, navigate to http://localhost:3000 to use Onyx.
+
+If you want to make changes to Onyx and run those changes in Docker, you can also build a local version of the Onyx container images that incorporates your changes:
+
+```bash
+docker compose up -d --build
+```
+
+---
+
+## macOS-Specific Notes
+
+### Setting up Python
+
+Ensure [Homebrew](https://brew.sh/) is already set up, then install Python 3.11:
+
+```bash
+brew install python@3.11
+```
+
+Add Python 3.11 to your path by adding the following line to `~/.zshrc`:
+
+```
+export PATH="$(brew --prefix)/opt/python@3.11/libexec/bin:$PATH"
+```
+
+> **Note:** You will need to open a new terminal for the path change above to take effect.
+
+### Setting up Docker
+
+On macOS, you will need to install [Docker Desktop](https://www.docker.com/products/docker-desktop/) and ensure it is running before continuing with the docker commands.
+
+### Formatting and Linting
+
+macOS will likely require you to remove some quarantine attributes on some of the hooks for them to execute properly. After installing pre-commit, run the following command:
+
+```bash
+sudo xattr -r -d com.apple.quarantine ~/.cache/pre-commit
+```
+

+
+## Engineering Best Practices
+
+> These are also what we adhere to as a team internally, we love to build in the open and to uplevel our community and each other through being transparent.
+
+### Principles and Collaboration
+
+- **Use 1-way vs 2-way doors.** For 2-way doors, move faster and iterate. For 1-way doors, be more deliberate.
+- **Consistency > being "right."** Prefer consistent patterns across the codebase. If something is truly bad, fix it everywhere.
+- **Fix what you touch (selectively).**
+  - Don't feel obligated to fix every best-practice issue you notice.
+  - Don't introduce new bad practices.
+  - If your change touches code that violates best practices, fix it as part of the change.
+- **Don't tack features on.** When adding functionality, restructure logically as needed to avoid muddying interfaces and accumulating tech debt.
+
+### Style and Maintainability
+
+#### Comments and readability
+Add clear comments:
+- At logical boundaries (e.g., interfaces) so the reader doesn't need to dig 10 layers deeper.
+- Wherever assumptions are made or something non-obvious/unexpected is done.
+- For complicated flows/functions.
+- Wherever it saves time (e.g., nontrivial regex patterns).
+
+#### Errors and exceptions
+- **Fail loudly** rather than silently skipping work.
+  - Example: raise and let exceptions propagate instead of silently dropping a document.
+- **Don't overuse `try/except`.**
+  - Put `try/except` at the correct logical level.
+  - Do not mask exceptions unless it is clearly appropriate.
+
+#### Typing
+- Everything should be **as strictly typed as possible**.
+- Use `cast` for annoying/loose-typed interfaces (e.g., results of `run_functions_tuples_in_parallel`).
+  - Only `cast` when the type checker sees `Any` or types are too loose.
+- Prefer types that are easy to read.
+  - Avoid dense types like `dict[tuple[str, str], list[list[float]]]`.
+  - Prefer domain models, e.g.:
+    - `EmbeddingModel(provider_name, model_name)` as a Pydantic model
+    - `dict[EmbeddingModel, list[EmbeddingVector]]`
+
+#### State, objects, and boundaries
+- Keep **clear logical boundaries** for state containers and objects.
+- A **config** object should never contain things like a `db_session`.
+- Avoid state containers that are overly nested, or huge + flat (use judgment).
+- Prefer **composition and functional style** over inheritance/OOP.
+- Prefer **no mutation** unless there's a strong reason.
+- State objects should be **intentional and explicit**, ideally nonmutating.
+- Use interfaces/objects to create clear separation of responsibility.
+- Prefer simplicity when there's no clear gain.
+  - Avoid overcomplicated mechanisms like semaphores.
+  - Prefer **hash maps (dicts)** over tree structures unless there's a strong reason.
+
+#### Naming
+- Name variables carefully and intentionally.
+- Prefer long, explicit names when undecided.
+- Avoid single-character variables except for small, self-contained utilities (or not at all).
+- Keep the same object/name consistent through the call stack and within functions when reasonable.
+  - Good: `for token in tokens:`
+  - Bad: `for msg in tokens:` (if iterating tokens)
+- Function names should bias toward **long + descriptive** for codebase search.
+  - IntelliSense can miss call sites; search works best with unique names.
+
+#### Correctness by construction
+- Prefer self-contained correctness — don't rely on callers to "use it right" if you can make misuse hard.
+- Avoid redundancies: if a function takes an arg, it shouldn't also take a state object that contains that same arg.
+- No dead code (unless there's a very good reason).
+- No commented-out code in main or feature branches (unless there's a very good reason).
+- No duplicate logic:
+  - Don't copy/paste into branches when shared logic can live above the conditional.
+  - If you're afraid to touch the original, you don't understand it well enough.
+  - LLMs often create subtle duplicate logic — review carefully and remove it.
+  - Avoid "nearly identical" objects that confuse when to use which.
+- Avoid extremely long functions with chained logic:
+  - Encapsulate steps into helpers for readability, even if not reused.
+  - "Pythonic" multi-step expressions are OK in moderation; don't trade clarity for cleverness.
+
+### Performance and Correctness
+
+- Avoid holding resources for extended periods (DB sessions, locks/semaphores).
+- Validate objects on creation and right before use.
+- Connector code (data to Onyx documents):
+  - Any in-memory structure that can grow without bound based on input must be periodically size-checked.
+  - If a connector is OOMing (often shows up as "missing celery tasks"), this is a top thing to check retroactively.
+- Async and event loops:
+  - Never introduce new async/event loop Python code, and try to make existing async code synchronous when possible if it makes sense.
+  - Writing async code without 100% understanding the code and having a concrete reason to do so is likely to introduce bugs and not add any meaningful performance gains.
+
+### Repository Conventions
+
+#### Where code lives
+- Pydantic + data models: `models.py` files.
+- DB interface functions (excluding lazy loading): `db/` directory.
+- LLM prompts: `prompts/` directory, roughly mirroring the code layout that uses them.
+- API routes: `server/` directory.
+
+#### Pydantic and modeling
+- Prefer **Pydantic** over dataclasses.
+- If absolutely required, use `allow_arbitrary_types`.
+
+#### Data conventions
+- Prefer explicit `None` over sentinel empty strings (usually; depends on intent).
+- Prefer explicit identifiers: use string enums instead of integer codes.
+- Avoid magic numbers (co-location is good when necessary). **Always avoid magic strings.**
+
+#### Logging
+- Log messages where they are created.
+- Don't propagate log messages around just to log them elsewhere.
+
+#### Encapsulation
+- Don't use private attributes/methods/properties from other classes/modules.
+- "Private" is private — respect that boundary.
+
+#### SQLAlchemy guidance
+- Lazy loading is often bad at scale, especially across multiple list relationships.
+- Be careful when accessing SQLAlchemy object attributes:
+  - It can help avoid redundant DB queries,
+  - but it can also fail if accessed outside an active session,
+  - and lazy loading can add hidden DB dependencies to otherwise "simple" functions.
+- Reference: https://www.reddit.com/r/SQLAlchemy/comments/138f248/joinedload_vs_selectinload/
+
+#### Trunk-based development and feature flags
+- **PRs should contain no more than 500 lines of real change.**
+- **Merge to main frequently.** Avoid long-lived feature branches — they create merge conflicts and integration pain.
+- **Use feature flags for incremental rollout.**
+  - Large features should be merged in small, shippable increments behind a flag.
+  - This allows continuous integration without exposing incomplete functionality.
+- **Keep flags short-lived.** Once a feature is fully rolled out, remove the flag and dead code paths promptly.
+- **Flag at the right level.** Prefer flagging at API/UI entry points rather than deep in business logic.
+- **Test both flag states.** Ensure the codebase works correctly with the flag on and off.
+
+#### Miscellaneous
+- Any TODOs you add in the code must be accompanied by either the name/username of the owner of that TODO, or an issue number for an issue referencing that piece of work.
+- Avoid module-level logic that runs on import, which leads to import-time side effects. Essentially every piece of meaningful logic should exist within some function that has to be explicitly invoked. Acceptable exceptions may include loading environment variables or setting up loggers.
+  - If you find yourself needing something like this, you may want that logic to exist in a file dedicated for manual execution (contains `if __name__ == "__main__":`) which should not be imported by anything else.
+- Do not conflate Python scripts you intend to run from the command line (contains `if __name__ == "__main__":`) with modules you intend to import from elsewhere. If for some unlikely reason they have to be the same file, any logic specific to executing the file (including imports) should be contained in the `if __name__ == "__main__":` block.
+  - Generally these executable files exist in `backend/scripts/`.

+is_reachable update policy
+--------------------------
+``is_reachable`` on the Hook row is updated selectively — only when the outcome
+carries meaningful signal about physical reachability:
+
+  NetworkError (DNS, connection refused)  → False  (cannot reach the server)
+  HTTP 401 / 403                          → False  (api_key revoked or invalid)
+  TimeoutException                        → None   (server may be slow, skip write)
+  Other HTTP errors (4xx / 5xx)           → None   (server responded, skip write)
+  Unknown exception                       → None   (no signal, skip write)
+  Non-JSON / non-dict response            → None   (server responded, skip write)
+  Success (2xx, valid dict)               → True   (confirmed reachable)
+
+None means "leave the current value unchanged" — no DB round-trip is made.
+
+DB session design
+-----------------
+The executor uses three sessions:
+
+  1. Caller's session (db_session) — used only for the hook lookup read. All
+     needed fields are extracted from the Hook object before the HTTP call, so
+     the caller's session is not held open during the external HTTP request.
+
+  2. Log session — a separate short-lived session opened after the HTTP call
+     completes to write the HookExecutionLog row on failure. Success runs are
+     not recorded. Committed independently of everything else.
+
+  3. Reachable session — a second short-lived session to update is_reachable on
+     the Hook. Kept separate from the log session so a concurrent hook deletion
+     (which causes update_hook__no_commit to raise OnyxError(NOT_FOUND)) cannot
+     prevent the execution log from being written. This update is best-effort.

 # Overview of Context Management
 
+This document reviews some design decisions around the main agent-loop powering Onyx's chat flow.
+It is highly recommended for all engineers contributing to this flow to be familiar with the concepts here.
+
+> Note: it is assumed the reader is familiar with the Onyx product and features such as Projects, User files, Citations, etc. 
+
 ## System Prompt
+
 The system prompt is a default prompt that comes packaged with the system. Users can edit the default prompt and it will be persisted in the database.
 
 Some parts of the system prompt are dynamically updated / inserted:
+
 - Datetime of the message sent
 - Tools description of when to use certain tools depending on if the tool is available in that cycle
 - If the user has just called a search related tool, then a section about citations is included
 
-
 ## Custom Agent Prompt
+
 The custom agent is inserted as a user message above the most recent user message, it is dynamically moved in the history as the user sends more messages.
 If the user has opted to completely replace the System Prompt, then this Custom Agent prompt replaces the system prompt and does not move along the history.
 
-
 ## How Files are handled
+
 On upload, Files are processed for tokens, if too many tokens to fit in the context, it’s considered a failed inclusion. This is done using the LLM tokenizer.
+
 - In many cases, there is not a known tokenizer for each LLM so there is a default tokenizer used as a catchall.
 - File upload happens in 2 parts - the actual upload + token counting.
 - Files are added into chat context as a “point in time” inclusion and move up the context window as the conversation progresses.
-Every file knows how many tokens it is (model agnostic), image files have some assumed number of tokens.

 access. Note that the project documents are assumed to be quite useful and that they should 1. never be dropped from context, 2. is not just a needle in

+Search tools also give URLs to the LLM so that open_url (a separate tool) can be called on them.
 
 ## Reminders
+
 To ensure the LLM follows certain specific instructions, instructions are added at the very end of the chat context as a user message. If a search related
 tool is used, a citation reminder is always added. Otherwise, by default there is no reminder. If the user configures reminders, those are added to the
 final message. If a search related tool just ran and the user has reminders, both appear in a single message.
 
 If a search related tool is called at any point during the turn, the reminder will remain at the end until the turn is over and the agent has responded.

+As tool call responses can get very long (like an internal search can be many thousands of tokens), tool responses are current replaced with a hardcoded
 string saying it is no longer available. Tool Call details like the search query and other arguments are kept in the history as this is information
 rich and generally very few tokens.
 
+> Note: in the Internal Search flow with query expansion, the Tool Call which was actually run differs from what the LLM provided as arguments.
+> What the LLM sees in the history (to be most informative for future calls) is the full set of expanded queries.
+
 **Possible Future Extension**:
 Instead of dropping the Tool Call response, we might summarize it using an LLM so that it is just 1-2 sentences and captures the main points. That said,
 this is questionable value add because anything relevant and useful should be already captured in the Agent response.

 Turn: User sends a message and AI does some set of things and responds
 Step/Cycle: 1 single LLM inference given some context and some tools
 
-
 ## 1. Top Level (process_message function):
+
 This function can be thought of as the set-up and validation layer. It ensures that the database is in a valid state, reads the
 messages in the session and sets up all the necessary items to run the chat loop and state containers. The major things it does
 are:
+
 - Validates the request
 - Builds the chat history for the session
 - Fetches any additional context such as files and images
 - Prepares all of the tools for the LLM
 - Creates the state container objects for use in the loop
 
-### Wrapper (run_chat_loop_with_state_containers function):
-This wrapper is used to run the LLM flow in a background thread and monitor the emitter for stop signals. This means the top
-level is as isolated from the LLM flow as possible and can continue to yield packets as soon as they are available from the lower
-levels. This also means that if the lower levels fail, the top level will still guarantee a reasonable response to the user.
-All of the saving and database operations are abstracted away from the lower levels.
+### Execution (`_run_models` function):
+
+Each model runs in its own worker thread inside a `ThreadPoolExecutor`. Workers write packets to a shared
+`merged_queue` via an `Emitter`; the main thread drains the queue and yields packets in arrival order. This
+means the top level is isolated from the LLM flow and can yield packets as soon as they are produced. If a
+worker fails, the main thread yields a `StreamingError` for that model and keeps the other models running.
+All saving and database operations are handled by the main thread after the workers complete (or by the
+workers themselves via self-completion if the drain loop exits early).
 
 ### Emitter
-The emitter is designed to be an object queue so that lower levels do not need to yield objects all the way back to the top.
-This way the functions can be better designed (not everything as a generator) and more easily tested. The wrapper around the
-LLM flow (run_chat_loop_with_state_containers) is used to monitor the emitter and handle packets as soon as they are available
-from the lower levels. Both the emitter and the state container are mutating state objects and only used to accumulate state.
-There should be no logic dependent on the states of these objects, especially in the lower levels. The emitter should only take
-packets and should not be used for other things.
+
+The emitter is an object that lower levels use to send packets without needing to yield them all the way back
+up the call stack. Each `Emitter` tags every packet with a `model_index` and places it on the shared
+`merged_queue` as a `(model_idx, packet)` tuple. The drain loop in `_run_models` consumes these tuples and
+yields the packets to the caller. Both the emitter and the state container are mutating state objects used
+only to accumulate state. There should be no logic dependent on the states of these objects, especially in
+the lower levels. The emitter should only take packets and should not be used for other things.
 
 ### State Container
+
 The state container is used to accumulate state during the LLM flow. Similar to the emitter, it should not be used for logic,
 only for accumulating state. It is used to gather all of the necessary information for saving the chat turn into the database.
 So it will accumulate answer tokens, reasoning tokens, tool calls, citation info, etc. This is used at the end of the flow once

 ### Stopping Generation
-A stop signal is checked every 300ms by the wrapper around the LLM flow. The signal itself
-is stored in Redis and is set by the user calling the stop endpoint. The wrapper ensures that no matter what the lower level is
-doing at the time, the thread can be killed by the top level. It does not require a cooperative cancellation from the lower level
-and in fact the lower level does not know about the stop signal at all.
 
+The drain loop in `_run_models` checks `check_is_connected()` every 50 ms (on queue timeout). The signal itself
+is stored in Redis and is set by the user calling the stop endpoint. On disconnect, the drain loop saves
+partial state for every model, yields an `OverallStop(stop_reason="user_cancelled")` packet, and returns.
+A `drain_done` event signals emitters to stop blocking so worker threads can exit quickly. Workers that
+already completed successfully will self-complete (persist their response) if the drain loop exited before
+reaching the normal completion path.
 
 ## 2. LLM Loop (run_llm_loop function)
+
 This function handles the logic of the Turn. It's essentially a while loop where context is added and modified (according what
 is outlined in the first half of this doc). Its main functionality is:
+
 - Translate and truncate the context for the LLM inference
 - Add context modifiers like reminders, updates to the system prompts, etc.
 - Run tool calls and gather results
 - Build some of the objects stored in the state container.
 
-
 ## 3. LLM Step (run_llm_step function)
+
 This function is a single inference of the LLM. It's a wrapper around the LLM stream function which handles packet translations
 so that the Emitter can emit individual tokens as soon as they arrive. It also keeps track of the different sections since they
 do not all come at once (reasoning, answers, tool calls are all built up token by token). This layer also tracks the different
 tool calls and returns that to the LLM Loop to execute.
 
-
 ## Things to know
-- Packets are labeled with a "turn_index" field as part of the Placement of the packet. This is not the same as the backend
-concept of a turn. The turn_index for the frontend is which block does this packet belong to. So while a reasoning + tool call
-comes from the same LLM inference (same backend LLM step), they are 2 turns to the frontend because that's how it's rendered.
 
-- There are 3 representations of "message". The first is the database model ChatMessage, this one should be translated away and
-not used deep into the flow. The second is ChatMessageSimple which is the data model which should be used throughout the code
-as much as possible. If modifications/additions are needed, it should be to this object. This is the rich representation of a
-message for the code. Finally there is the LanguageModelInput representation of a message. This one is for the LLM interface
-layer and is as stripped down as possible so that the LLM interface can be clean and easy to maintain/extend.

-is_reachable update policy
---------------------------
-``is_reachable`` on the Hook row is updated selectively — only when the outcome
-carries meaningful signal about physical reachability:
-
-  NetworkError (DNS, connection refused)  → False  (cannot reach the server)
-  HTTP 401 / 403                          → False  (api_key revoked or invalid)
-  TimeoutException                        → None   (server may be slow, skip write)
-  Other HTTP errors (4xx / 5xx)           → None   (server responded, skip write)
-  Unknown exception                       → None   (no signal, skip write)
-  Non-JSON / non-dict response            → None   (server responded, skip write)
-  Success (2xx, valid dict)               → True   (confirmed reachable)
-
-None means "leave the current value unchanged" — no DB round-trip is made.
-
-DB session design
------------------
-The executor uses three sessions:
-
-  1. Caller's session (db_session) — used only for the hook lookup read. All
-     needed fields are extracted from the Hook object before the HTTP call, so
-     the caller's session is not held open during the external HTTP request.
-
-  2. Log session — a separate short-lived session opened after the HTTP call
-     completes to write the HookExecutionLog row on failure. Success runs are
-     not recorded. Committed independently of everything else.
-
-  3. Reachable session — a second short-lived session to update is_reachable on
-     the Hook. Kept separate from the log session so a concurrent hook deletion
-     (which causes update_hook__no_commit to raise OnyxError(NOT_FOUND)) cannot
-     prevent the execution log from being written. This update is best-effort.
+execute_hook is the public entry point. It dispatches to _execute_hook_impl
+via fetch_versioned_implementation so that:
