-- For Gemini: files are re-read (updating the `file_items` list in place) but cannot be injected into tool results due to Gemini's structured function response format
+- After the last tool call in each round, all project files from `file_items` are re-read from disk via `_reread_file_items()`. The `file_items` variable is reassigned so subsequent rounds see fresh content.
+- For Anthropic: the refreshed file contents are injected as a `text` block appended to the `tool_results` user message, prefixed with `[FILES UPDATED]` and an instruction not to re-read them.
+- For Gemini: refreshed file contents are appended to the last function response's `output` string as a `[SYSTEM: FILES UPDATED]` block. On the next tool round, stale `[FILES UPDATED]` blocks are stripped from history and old tool outputs are truncated to `_history_trunc_limit` characters to control token growth.
 - `_build_file_context_text(file_items)` formats the refreshed files as markdown code blocks (same format as the original context)
 - The `tool_result_send` comms log entry filters out the injected text block (only logs actual `tool_result` entries) to keep the comms panel clean
 - `file_items` flows from `aggregate.build_file_items()` → `gui.py` `self.last_file_items` → `ai_client.send(file_items=...)` → `_send_anthropic(file_items=...)` / `_send_gemini(file_items=...)`

-- First user message content[0] is the `<context>` block with `cache_control: ephemeral`; content[1] is the user question without cache control
+- System prompt + context are combined into one string, chunked into <=120k char blocks, and sent as the `system=` parameter array. Only the LAST chunk gets `cache_control: ephemeral`, so the entire system prefix is cached as one unit.
+- Last tool in `_ANTHROPIC_TOOLS` (`run_powershell`) has `cache_control: ephemeral`; this means the tools prefix is cached together with the system prefix after the first request.
+- The user message is sent as a plain `[{"type": "text", "text": user_message}]` block with NO cache_control. The context lives in `system=`, not in the first user message.
+- The tools list is built once per session via `_get_anthropic_tools()` and reused across all API calls within the tool loop, avoiding redundant Python-side reconstruction.
+- `_strip_cache_controls()` removes stale `cache_control` markers from all history entries before each API call, ensuring only the stable system/tools prefix consumes cache breakpoint slots.

 ### Gemini Context Management
-- Investigating ways to prevent context duplication in _gemini_chat history, as currently <context>{md_content}</context> is prepended to the user message on every single request, causing history bloat.
-- Discussing explicit Gemini Context Caching API (client.caches.create()) to store read-only file context and avoid re-reading files across sessions.
+- Gemini uses explicit caching via `client.caches.create()` to store the `system_instruction` + tools as an immutable cached prefix with a 1-hour TTL. The cache is created once per chat session.
+- When context changes (detected via `md_content` hash), the old cache is deleted, a new cache is created, and chat history is migrated to a fresh chat session pointing at the new cache.
+- If cache creation fails (e.g., content is under the minimum token threshold — 1024 for Flash, 4096 for Pro), the system falls back to inline `system_instruction` in the chat config. Implicit caching may still provide cost savings in this case.
+- The `<context>` block lives inside `system_instruction`, NOT in user messages, preventing history bloat across turns.
+- On cleanup/exit, active caches are deleted via `ai_client.cleanup()` to prevent orphaned billing.

+Instead of sending every file to the AI raw (which blows up tokens), this uses a pipeline:
+1. Resolve paths (handles globs and absolute paths).
+2. Build file items (raw content).
+3. If 'summary_only' is true (which is the default behavior now), it pipes the files through

+# Manual Slop
+
+A GUI orchestrator for local LLM-driven coding sessions, built to prevent the AI from running wild and to provide total transparency into the context and execution state.
+
+## Core Management Panels
+
+### Projects Panel
+
+The heart of context management. 
+
+> **Note:** The Config panel has been removed. Output directory and auto-add history settings are now integrated into the Projects and Discussion History panels respectively.
+
+- **Configuration:** You specify the Git Directory (for commit tracking) and a Main Context File (the markdown file containing your project's notes and schema).
+- **Word-Wrap Toggle:** Dynamically swaps text rendering in large read-only panels (Responses, Comms Log) between unwrapped (ideal for viewing precise code formatting) and wrapped (ideal for prose).
+- **Project Switching:** Switch between different <project>.toml profiles to instantly swap out your entire active file list, discussion history, and settings.
+
+### Discussion History
+
+Manages your conversational branches, preventing context poisoning across different tasks.
+
+- **Discussions Sub-Menu:** Allows you to create separate timelines for different tasks (e.g., "Refactoring Auth" vs. "Adding API Endpoints"). 
+- **Git Commit Tracking:** Clicking "Update Commit" reads HEAD from your project's git directory and stamps the discussion. 
+- **Entry Management:** Each turn has a Role (User, AI, System). You can toggle entries between **Read** and **Edit** modes, collapse them, or hit [+ Max] to open them in the Global Text Viewer.
+- **Auto-Add:** If toggled, anything sent from the "Message" panel and returned to the "Response" panel is automatically appended to the current discussion history.
+
+### Files & Screenshots
+
+Controls what is explicitly fed into the context compiler.
+
+- **Base Dir:** Defines the root for path resolution and tool constraints.
+- **Paths:** Explicit files or wildcard globs (e.g., src/**/*.rs). 
+- When generating a request, these files are summarized symbolically (summarize.py) to conserve tokens, unless the AI explicitly decides to read their full contents via its internal tools.
+
+## Interaction Panels
+
+### Provider
+
+Switch between API backends (Gemini, Anthropic) on the fly. Clicking "Fetch Models" queries the active provider for the latest model list.
+
+### Message & Response
+
+- **Message:** Your input field. 
+- **Gen + Send:** Compiles the markdown context and dispatches the background thread to the AI.
+- **MD Only:** Dry-runs the compiler so you can inspect the generated <project>_00N.md without triggering an API charge.
+- **Response:** The read-only output. Flashes green when a new response arrives. 
+
+### Global Text Viewer & Script Outputs
+
+- **Last Script Output:** Whenever the AI executes a background script, this window pops up, flashing blue. It contains both the executed script and the stdout/stderr.
+- **Text Viewer:** A large, resizable global popup invoked anytime you click a [+] or [+ Maximize] button in the UI. Used for deep-reading long logs, discussion entries, or script bodies.
+
+## System Prompts
+
+Provides two text inputs for overriding default instructions:
+
+1. **Global:** Applied across every project you load.
+2. **Project:** Specific to the active workspace.
+These are concatenated onto the strict tool-usage guidelines the agent is initialized with.

+# Guide: Architecture
+
+Overview of the package design, state management, and code-path layout.
+
+---
+
+The purpose of this software is to alleviate the pain points of using AI as a local co-pilot by encapsulating the workflow into a resilient, strictly controlled state machine. It manages context generation, API throttling, human-in-the-loop tool execution, and session-long logging.
+
+There are two primary state boundaries used:
+
+* The GUI State (Main Thread, Retained-Mode via Dear PyGui)
+* The AI State (Daemon Thread, stateless execution loop)
+
+All synchronization between these boundaries is managed via lock-protected queues and events.
+
+## Code Paths
+
+### Lifetime & Application Boot
+
+The application lifetime is localized within App.run in gui.py.
+
+1. __init__ parses the global config.toml (which sets the active provider, theme, and project paths).
+2. It immediately hands off to project_manager.py to deserialize the active <project>.toml which hydrates the session's files, discussion histories, and prompts.
+3. Dear PyGui's dpg contexts are bootstrapped with docking_viewport=True, allowing individual GUI panels to exist as native OS windows.
+4. The main thread enters a blocking while dpg.is_dearpygui_running() render loop.
+5. On shutdown (clean exit), it performs a dual-flush: _flush_to_project() commits the UI state back to the <project>.toml, and _flush_to_config() commits the global state to config.toml. The viewport layout is automatically serialized to dpg_layout.ini.
+
+### Context Shaping & Aggregation
+
+Before making a call to an AI Provider, the current state of the workspace is resolved into a dense Markdown representation. 
+This occurs inside aggregate.run.
+
+If using the default workflow, aggregate.py hashes through the following process:
+
+1. **Glob Resolution:** Iterates through config["files"]["paths"] and unpacks any wildcards (e.g., src/**/*.rs) against the designated base_dir.
+2. **Summarization Pass:** Instead of concatenating raw file bodies (which would quickly overwhelm the ~200k token limit over multiple rounds), the files are passed to summarize.py.
+3. **AST Parsing:** summarize.py runs a heuristic pass. For Python files, it uses the standard ast module to read structural nodes (Classes, Methods, Imports, Constants). It outputs a compact Markdown table.
+4. **Markdown Generation:** The final <project>_00N.md string is constructed, comprising the truncated AST summaries, the user's current project system prompt, and the active discussion branch. 
+5. The Markdown file is persisted to disk (./md_gen/ by default) for auditing.
+
+### AI Communication & The Tool Loop
+
+The communication model is unified under ai_client.py, which normalizes the Gemini and Anthropic SDKs into a singular interface send(md_content, user_message, base_dir, file_items).
+
+The loop is defined as follows:
+
+1. **Prompt Injection:** The aggregated Markdown context and system prompt are injected. For Gemini, the system_instruction and tools are stored in an explicit cache via `client.caches.create()` with a 1-hour TTL; if cache creation fails (under minimum token threshold), it falls back to inline system_instruction. When context changes mid-session, the old cache is deleted and a new one is created. For Anthropic, the system prompt + context are sent as `system=` blocks with `cache_control: ephemeral` on the last chunk, and tools carry `cache_control: ephemeral` on the last tool definition.
+2. **Execution Loop:** A MAX_TOOL_ROUNDS (default 10) bounded loop begins. The tools list for Anthropic is built once per session and reused.
+3. The AI provider is polled.
+4. If the provider's stop_reason is tool_use:
+   1. The loop parses the requested tool (either a read-only MCP tool or the destructive PowerShell tool).
+   2. If PowerShell, it dispatches a blocking event to the Main Thread (see *On Tool Execution & Concurrency*).
+   3. Once the last tool result in the batch is retrieved, the loop executes a **Dynamic Refresh** (`_reread_file_items`). Any files currently tracked by the project are pulled from disk fresh. The `file_items` variable is reassigned so subsequent tool rounds see the updated content.
+   4. For Anthropic: the refreshed file contents are appended as a text block to the tool_results user message. For Gemini: the refreshed contents are appended to the last function response's output string. In both cases, the block is prefixed with `[FILES UPDATED]` / `[SYSTEM: FILES UPDATED]`.
+   5. On subsequent rounds, stale file-refresh blocks from previous turns are stripped from history to prevent token accumulation. For Gemini, old tool outputs exceeding `_history_trunc_limit` characters are also truncated.
+5. Once the model outputs standard text, the loop terminates and yields the string back to the GUI callback.
+
+### On Tool Execution & Concurrency
+
+When the AI calls a safe MCP tool (like read_file or search_files), the daemon thread immediately executes it via mcp_client.py and returns the result.
+
+However, when the AI requests run_powershell, the operation halts:
+
+1. The Daemon Thread instantiates a ConfirmDialog object containing the payload and calls .wait(). This blocks the thread on a threading.Event().
+2. The ConfirmDialog instance is safely placed in a _pending_dialog_lock.
+3. The Main Thread, during its next frame cycle, pops the dialog from the lock and renders an OS-level modal window using dpg.window(modal=True).
+4. The user can inspect the script, modify it in the text box, or reject it entirely.
+5. Upon the user clicking "Approve & Run", the main thread triggers the threading.Event, unblocking the Daemon Thread.
+6. The Daemon Thread passes the script to shell_runner.py, captures stdout, stderr, and exit_code, logs it to session_logger.py, and returns it to the LLM.
+
+### On Context History Pruning (Anthropic)
+
+Because the Anthropic API requires sending the entire conversation history on every request, long sessions will inevitably hit the invalid_request_error: prompt is too long.
+
+To solve this, ai_client.py implements an aggressive pruning algorithm:
+
+1. _strip_stale_file_refreshes: It recursively sweeps backward through the history dict and strips out large [FILES UPDATED] data blocks from old turns, preserving only the most recent snapshot.
+2. _trim_anthropic_history: If the estimated token count still exceeds _ANTHROPIC_MAX_PROMPT_TOKENS (~180,000), it slices off the oldest user/assistant message pairs from the beginning of the history array.
+3. The loop guarantees that at least the System prompt, Tool Definitions, and the final user prompt are preserved.
+
+### Session Persistence
+
+All I/O bound session data is recorded sequentially. session_logger.py hooks into the execution loops and records:
+
+- logs/comms_<ts>.log: A JSON-L structured timeline of every raw payload sent/received.
+- logs/toolcalls_<ts>.log: A sequential markdown record detailing every AI tool invocation and its exact stdout result.
+- scripts/generated/: Every .ps1 script approved and executed by the shell runner is physically written to disk for version control transparency.

+# Guide: Tooling
+
+Overview of the tool dispatch and execution model.
+
+---
+
+The agent is provided two classes of tools: Read-Only MCP Tools, and a Destructive Execution Loop.
+
+## 1. Read-Only Context (MCP Tools)
+
+Implemented in mcp_client.py. These tools allow the AI to selectively expand its knowledge of the codebase without requiring the user to dump entire 10,000-line files into the static context prefix.
+
+### Security & Scope
+
+Every filesystem MCP tool passes its arguments through _resolve_and_check. This function ensures that the requested path falls under one of the allowed directories defined in the GUI's Base Dir configurations. 
+If the AI attempts to read or search a path outside the project bounds, the tool safely catches the constraint violation and returns ACCESS DENIED.
+
+### Supplied Tools:
+
+* read_file(path): Returns the raw UTF-8 text of a file.
+* list_directory(path): Returns a formatted table of a directory's contents, showing file vs dir and byte sizes.
+* search_files(path, pattern): Executes an absolute glob search (e.g., **/*.py) to find specific files.
+* get_file_summary(path): Invokes the local summarize.py heuristic parser to get the AST structure of a file without reading the whole body.
+* web_search(query): Queries DuckDuckGo's raw HTML endpoint and returns the top 5 results (Titles, URLs, Snippets) using a native HTMLParser to avoid heavy dependencies.
+* fetch_url(url): Downloads a target webpage and strips out all scripts, styling, and structural HTML, returning only the raw prose content (clamped to 40,000 characters).
+
+## 2. Destructive Execution (run_powershell)
+
+The core manipulation mechanism. This is a single, heavily guarded tool.
+
+### Flow
+
+1. The AI generates a 'run_powershell' payload containing a PowerShell script.
+2. The AI background thread calls confirm_and_run_callback (injected by gui.py).
+3. The background thread blocks completely, creating a modal popup on the main GUI thread.
+4. The user reads the script and chooses to Approve or Reject.
+5. If Approved, shell_runner.py executes the script using -NoProfile -NonInteractive -Command within the specified base_dir.
+6. The combined stdout, stderr, and EXIT CODE are captured and returned to the AI in the tool result block.
+
+### AI Guidelines
+
+The core system prompt explicitly guides the AI on how to use this tool safely:
+
+* Prefer targeted replacements (using PowerShell's .Replace()) over full rewrites where possible.
+* If a file is large and complex (requiring specific escape characters), do not attempt an inline python -c script. Instead, use a PowerShell here-string (@'...'@) to write a temporary python helper script to disk, execute the python script, and then delete it.
+
+### Synthetic Context Refresh
+
+After the **last** tool call in each round finishes (when multiple tools are called in a single round, the refresh happens once after all of them), ai_client runs `_reread_file_items`. It fetches the latest disk state of all files in the current project context. The `file_items` variable is reassigned so subsequent tool rounds within the same request use the fresh content.
+
+For Anthropic, the refreshed contents are injected as a text block in the `tool_results` user message. For Gemini, they are appended to the last function response's output string. In both cases, the block is prefixed with `[FILES UPDATED]` / `[SYSTEM: FILES UPDATED]`.
+
+On the next tool round, stale file-refresh blocks from previous rounds are stripped from history to prevent token accumulation. This means if the AI writes to a file, it instantly "sees" the modification in its next turn without having to waste a cycle calling `read_file`, and the cost of carrying the full file snapshot is limited to one round.

I will now implement the two pending features: adding a global word-wrap toggle to the project settings and making the discussion entry text boxes maximizable.\n\nFirst, I'll add the `word_wrap` setting to the default project configuration so that all new projects have this option available.\nI will start by adding the `word_wrap` setting to the project configuration. I'll edit `project_manager.py` to include `word_wrap = True` in the `default_project` function. This ensures that all newly created projects will have this setting enabled by default.\n\nExcellent. Now I will modify `gui.py` to add the user interface elements and logic for both the word-wrap toggle and the maximizable discussion entries.\n\nThis involves several targeted changes:\n1.  **App State**: I'll add a list to the `App` class to keep track of all text widgets that need to have their wrapping toggled.\n2.  **UI Construction (`_build_ui`)**: A new checkbox for \"Word-Wrap\" will be added to the \"Projects\" panel.\n3.  **Callback Logic (`cb_word_wrap_toggled`)**: This new function will iterate through the tracked widgets and apply the word-wrap setting. I will also make sure that dynamically created text elements (like in the tool and comms logs) respect this setting upon being rendered.\n4.  **Discussion History (`_rebuild_disc_list`)**: I'll add a `[+ Max]` button next to each discussion entry's text box, hooking it up to the existing text viewer popup.\n\nI will write a Python script to perform these modifications.\n\nThe previous attempt to modify `gui.py` failed due to a syntax error in the helper script. PowerShell misinterpreted a backslash in a regular expression. I will correct this by writing a new, more robust Python script to perform the necessary edits.\n\nThis new script will:\n1.  Add a `[+ Max]` button to each discussion history entry, allowing its content to be opened in the global text viewer.\n2.  Add the \"Word-Wrap\" checkbox to the project settings panel.\n3.  Implement the logic for the word-wrap toggle, ensuring it correctly shows/hides wrapped and non-wrapped text panels and redraws dynamic content like the comms and tool logs.\n4.  Update the text viewer popup so that its own wrapping behaviour is also controlled by the new project setting.\n\nI will now execute this corrected script.\n\nExcellent. The script has successfully modified `gui.py` to implement the requested features.\n\nHere is a summary of the final changes:\n\n1.  **Global Word-Wrap Toggle (`gui.py`, `project_manager.py`)**:\n    *   A new setting, `word_wrap`, has been added to the project configuration (`.toml` files) and defaults to `true`.\n    *   A checkbox labeled \"Word-Wrap (Read-only panels)\" is now present in the **Projects** panel.\n    *   Toggling this checkbox will dynamically change the wrapping behavior for most multi-line text displays in the interface, including the main AI response, script outputs, the global text viewer, and the comms log.\n\n2.  **Maximizable Discussion Entries (`gui.py`)**:\n    *   Each entry in the **Discussion History** panel now has a `[+ Max]` button.\n    *   Clicking this button will open the full content of that specific entry in the large **Text Viewer** popup, making it much easier to read and review long conversation segments.\n\nI have completed all the requested tasks. I will now update `MainContext.md` to document these new UI enhancements.\n\nI have now implemented all the requested features and updated the documentation.\n\n1.  **Word-Wrap Feature**: A \"Word-Wrap\" checkbox is now available in the **Projects** panel. This setting is saved with your project and controls the text wrapping for most read-only text panels throughout the application, allowing you to toggle between wrapped text for readability and non-wrapped text for viewing code.\n\n2.  **Maximizable Discussion Entries**: Every entry in the **Discussion History** now has a `[+ Max]` button, enabling you to open its contents in the large text viewer for easier reading and copying.\n\n3.  **Documentation Updated**: `MainContext.md` has been updated to include details about these new quality-of-life features.\n\nAll tasks are complete. You will need to restart the application to see and use the new features. Let me know if you have any other requests",

Which c++ imgui supports. I think there might be a python package that supports this.\n\nWorst case I might have to use a different language that has a dear imgui package with multi-viewporting support that may make ai codegen performance far worse.",
+    "@2026-02-22T01:15:32\nAI:\nAlright, I've done extensive research on this. Here's my assessment:\n\n## The Multi-Viewport Situation in Python\n\n### The Problem with DearPyGui\nDearPyGui wraps Dear ImGui but **does not expose the multi-viewport feature** (dragging imgui windows out as independent OS windows). It has its own docking implementation but the C++ multi-viewport backend plumbing was never wired through to Python. You've already discovered this the hard way.\n\n### The Best Option: `imgui-bundle` (pip: `imgui-bundle`)\n\n**This is the package you want.** It's by Pascal Thomet (pthom) and wraps:\n- **Dear ImGui** (docking branch — which includes multi-viewport support)\n- **Hello ImGui** (application framework on top of Dear ImGui)\n- 20+ additional libraries (plots, markdown, node editors, etc.)\n\nKey facts:\n- `pip install imgui-bundle` — binary wheels for Windows/macOS/Linux\n- It tracks Dear ImGui's **docking branch** closely, which is the branch that contains `ImGuiConfigFlags_ViewportsEnable`\n- Full Python bindings with type hints\n- The API uses `imgui.config_flags` to set `ImGuiConfigFlags_ViewportsEnable`, then Dear ImGui handles creating/managing OS windows automatically when you drag an imgui window outside the main viewport\n- Has its own layout/docking system via Hello ImGui's dock spaces\n\n### What the Port Involves\n\nThis is a **massive** rewrite. The entire `gui.py` (2094 lines) and `theme.py` (415 lines) are completely DearPyGui-specific. Every single widget call, every tag system, every callback pattern is different. Here's the mapping:\n\n| DearPyGui | imgui-bundle |\n|---|---|\n| `dpg.add_text(...)` | `imgui.text(...)` |\n| `dpg.add_input_text(tag=..., ...)` | State variable + `imgui.input_text(...)` |\n| `dpg.add_button(label=..., callback=...)` | `if imgui.button(\"label\"): do_thing()` |\n| Tag-based widget identity | Immediate mode — no tags, state lives in your code |\n| `dpg.does_item_exist(tag)` | Not needed — immediate mode |\n| `dpg.configure_item(tag, ...)` | Just change the variable and it renders next frame |\n| `dpg.create_viewport()` + render loop | `hello_imgui.run(gui_func, params)` |\n| `dpg.enable_docking()` | `runner_params.imgui_window_params.enable_viewports = True` |\n| Theme via `dpg.add_theme_color()` | `imgui.push_style_color()` / `imgui.get_style()` |\n\nThe immediate-mode paradigm is actually **simpler** conceptually — no tags, no \"does item exist\" checks, no callback registration. But it means a full rewrite of all rendering code.\n\n### My Recommendation\n\n**Do the port to `imgui-bundle`.** Here's why:\n1. It definitively supports multi-viewporting (the whole point)\n2. The immediate-mode API is actually cleaner and more maintainable\n3. Better AI codegen compatibility (pthom specifically calls this out — readable code)\n4. You stay in Python — no language switch needed\n5. Active maintenance tracking upstream Dear ImGui\n\n### How I'd Structure the Port\n\n1. **Phase 1**: Install `imgui-bundle`, create a minimal proof-of-concept with multi-viewporting enabled (verify it works on your machine)\n2. **Phase 2**: Port `theme.py` → new imgui-bundle theming\n3. **Phase 3**: Port `gui.py` — the big one. Rewrite all panels as immediate-mode rendering functions\n4. **Phase 4**: Wire up the threading/callbacks (confirmation dialogs, background sends, etc.)\n\n**Want me to start with Phase 1 — a minimal proof-of-concept** that creates a window with viewports enabled, a couple of dockable panels, and verifies you can drag a panel out as an independent OS window? That way we confirm the foundation works before committing to the full rewrite.\n\nOr if you want me to just go all-in and start the full port, I can do that too. Your call.",
+    "@2026-02-22T01:18:08\nUser:\nYeah lets do the port, lets make a gui_2.py for this port so you don't have to worry about gui.py modifications directly. You can be incremental about it as well and have me test between steps. and I can keep the old ui as we progress.\nIf you can somedhow do the entire thing in one go congrats. \nMake a theme_2.py as well for gui_2.py if it needs a port as well.\nWhen we're done we'll make these the main scripts (rename to gui.py and theme.py, delete old ones, etc).",
+    "@2026-02-22T01:22:47\nAI:\nOK, this is a massive port. Let me first read the existing `theme.py` and `MainContext.md`, then I'll build both `theme_2.py` and `gui_2.py` as complete files.\nThis is a massive port. Let me start by understanding the full picture, then I'll write both `theme_2.py` and `gui_2.py` as complete files. First let me install `imgui-bundle` and verify it works, then write the files.\nLet me first check if imgui-bundle is installed:\nGood, `imgui-bundle` is installed and working with ImGui 1.92.5 (docking branch). Now let me build the two files. This is a massive port so I'll write them as Python helper scripts to disk.\nLet me start with `theme_2.py` since it's simpler and `gui_2.py` depends on it:\nGood, `theme_2.py` is written. Now I need to write the massive `gui_2.py`. This is the big one — a complete port from DearPyGui's retained-mode tag-based system to imgui-bundle's immediate-mode paradigm. I'll write it as a Python helper script since it's too large and complex for a PowerShell here-string.\nLet me write the helper script that creates `gui_2.py`:",

Please save the following code manually as `gui_2.py` in your project folder. \n\nThis is the massive port completing the transition to `imgui-bundle`.
