-# Module Organization Summary
+# Frontend Module Organization Summary
 
-## Purpose
-This document describes what each JavaScript module is responsible for.
-
-> **Note:** This file is a partial, historical overview — not a complete authoritative
-> inventory. The authoritative module set is the current `static/js/` tree plus the
-> scripts loaded by `static/index.html`. As of this writing that tree holds **65 `.js`
-> files** across **8 subdirectories** (`calendar/`, `color/`, `compare/`, `editor/`,
-> `emailLibrary/`, `markdown/`, `research/`, `util/`), and `static/index.html` loads
-> **35** `/static…` script tags. The catalog below covers only the original core
-> modules and is not kept in sync with every module.
+> **Scope:** This document describes the architecture of the Odysseus no-build
+> frontend. The app is a collection of native ES6 modules loaded from
+> `static/`. The authoritative source is the current `static/js/` tree and the
+> top-level orchestrator `static/app.js`.
 
 ---
 
-## Core Modules (in static/js/)
+## 1. Top-level Application Orchestrator
 
-### 1. **ui.js**
-- UI helper functions and utilities
-- Toast notifications (`showToast`, `showError`)
-- Element getter (`el()`)
-- Clipboard operations (`copyToClipboard`)
-- Scroll management (`scrollHistory`, `setAutoScroll`)
-- Auto-resize textarea
-- Debounce utility
+### `static/app.js`
+*Main application entry point.*
 
-### 2. **markdown.js**
-- Markdown processing and rendering
-- Convert markdown to HTML (`mdToHtml`)
-- Code block handling with syntax highlighting
-- Content rendering for message arrays
-- Text cleanup (`squashOutsideCode`)
+- Imports all feature modules.
+- Exposes a few modules on `window` for legacy inter-module reachability
+  (`themeModule`, `sessionModule`, `uiModule`, `adminModule`, `cookbookModule`).
+- Patches `fetch` so any `401` redirects the user to `/login`.
+- Fetches the default chat configuration and handles deep-link route openers
+  (`/notes`, `/calendar`, `/email`, `/memory`, `/gallery`, `/cookbook`, `/library`, `/tasks`).
+- Wires global event listeners: chat-history scrolling, popups, Escape handling,
+  drag-and-drop/paste attachment handling, transcription export, sidebar toggles,
+  rail/tool buttons, and session sorting.
+- Loads auth status and applies per-user privilege restrictions.

+## 3. Chat Pipeline
+
+The largest and most central subsystem. Chat submission → backend SSE → progressive rendering of text, tools, research, documents, and UI events.
+
+| Module | Responsibility |
+|---|---|
+| **`chat.js`** | Main chat controller. Handles `handleChatSubmit`, stops/continues, builds `FormData`, posts to `/api/chat_stream`, reads the SSE stream, and dispatches each JSON event to the appropriate renderer. Tracks background streams, stalls, auto-recovery, and multi-round agent state. |
+| **`chatStream.js`** | Helpers shared between streaming consumers: browser notifications, background-stream completion toasts, and `ui_control` event handling. |
+| **`chatRenderer.js`** | Message DOM construction: `addMessage`, role labels, model route labels, color coding, footers, metrics, code blocks, sources boxes (`web`/`research`/`RAG`), findings box, images, report links, ask-user cards, welcome screen, and transcript utilities. |
+| **`streamingRenderer.js`** | Incremental streaming renderer used by `chat.js`. Freezes finalized DOM blocks and only re-renders the growing tail to avoid flicker and O(N²) re-parsing. |
+| **`streamingSegmenter.js`** | Splits a token stream into display units (text vs code fences) for `streamingRenderer.js`. |
+| **`slashCommands.js`** | Slash-command registry (`/help`, `/setup`, etc.), parsing, and dispatch handlers. Exported functions are consumed by `chat.js` and `slashAutocomplete.js`. |
+| **`slashAutocomplete.js`** | Composer autocomplete popup for `/` commands. |
+| **`composerArrowUpRecall.js`** | Recall last user message with `↑` on an empty composer. |
+| **`assistant.js`** | Assistant/persona behaviors and message styling helpers. |
+| **`tts-ai.js`** | AI text-to-speech manager, enqueueing, streaming TTS, and playback button injection. |
+| **`voiceRecorder.js`** | Voice recording from the composer microphone. |
+| **`fileHandler.js`** | Attachment picker, paste/drop handling, upload, attachment strip rendering, pending-file management. |
+| **`codeRunner.js`** | Client-side execution affordances for code blocks returned by the model. |

+
+---
+
+## 12. Frontend Event Streaming Flow
+
+```
+User submits composer
+  └── chat.js::handleChatSubmit() builds FormData
+        ├── fileHandler.uploadPending() for attachments
+        ├── document.js saved (if a document panel is open)
+        └── POST /api/chat_stream
+
+Server responds with SSE stream
+  └── chat.js reads chunks via res.body.getReader() + TextDecoder
+        ├── Lines starting with "event:" set next-error state
+        └── Lines starting with "data:" carry JSON payloads
+
+JSON events are dispatched by "type":
+  delta              → streamingRenderer → markdown → live reply text
+  agent_prep         → update spinner label
+  tool_start         → finalize text bubble; create agent-thread node with wave animation
+  tool_progress      → append/update live stdout/stderr tail
+  tool_output        → mark node done/failed, render output, diffs, screenshots
+  agent_step         → finalize tool thread; create new msg-continuation bubble
+  doc_stream_open    → document.js opens a live document
+  doc_stream_delta   → document.js appends content to that document
+  research_progress  → researchSynapse visualization + spinner timer
+  research_sources   → build sources box for research
+  research_done      → reload session history to show the report
+  web_sources        → build web-search sources box
+  model_info         → update role header with requested/actual model
+  fallback           → show fallback model toast + update role label
+  metrics            → collect/display token/cost metrics
+  message_saved      → store database id on the message element
+  budget_exceeded    → show budget banner
+  rounds_exhausted   → show Continue button for step-limit hits
+  teacher_takeover   → insert escalation banner, reset round state
+  skill_saved        → show skill-learned banner
+```
+
+Foreground vs background streams:
+- If the user switches sessions while a stream is running, `chat.js` pauses DOM
+  updates and stores the state in `_backgroundStreams`. Completion is signaled
+  with a sidebar dot/notifications, and the history is reloaded when the user
+  returns.
+
+---
+
+## 13. What Changed from the Previous Summary
+
+- The frontend is now exclusively ES6-module based; the old `<script>` tag load
+  order is no longer authoritative.
+- `chat.js` is the streaming controller, but message rendering has been split
+  into `chatRenderer.js`, `streamingRenderer.js`, `chatStream.js`, and `researchSynapse.js`.
+- New major subsystems added since the original summary: compare mode
+  (`compare/`), document editor streaming (`document.js`), research UI
+  (`research/`), model cookbook (`cookbook*.js`), group chat (`group.js`),
+  voice/TTS (`voiceRecorder.js`, `tts-ai.js`), skill UI (`skills.js`), and
+  slash autocomplete (`slashAutocomplete.js`).
+- `sessions.js` now owns sidebar session state, streaming/research indicators,
+  and the library/archive modals.
