+## `src/scanner.py` — UniversalResource, ScanResult, StarryScanner
+
+### `UniversalResource` (dataclass)
+
+```python
+@dataclass
+class UniversalResource:
+ file_path: str # Absolute path to the file
+ mime_type: str # MIME type (e.g., 'image/jpeg', 'application/pdf')
+ raw_data: Any # Path reference for downstream processing
+ size_bytes: int = 0 # File size in bytes
+```
+
+**Purpose:** Immutable container for a discovered file. The `StarryEngine` uses `mime_type` to route the file to the correct analyzer (`_analyze_image`, `_analyze_pdf`, or `_analyze_text`).
+
+**Design Decision:** `raw_data` is set to the file path rather than the file contents because images and PDFs can be very large. Loading them eagerly would exhaust memory. Instead, each analyzer loads the file on demand.
+
+---
+
+### `ScanResult` (dataclass)
+
+```python
+@dataclass
+class ScanResult:
+ resources: List[UniversalResource] # All discovered files
+ total_bytes: int = 0 # Sum of all file sizes
+ skipped_count: int = 0 # Files/dirs skipped by filter
+ error_count: int = 0 # Files that failed to scan
+ errors: List[str] = [] # Error messages
+```
+
+**Purpose:** Aggregated output from a directory scan. Provides statistics for the TUI (total bytes, file count) and error tracking for robustness.
+
+**Property:**
+- `count` → `int`: Returns `len(self.resources)`.
+
+---
+
+### `StarryScanner`
+
+#### `__init__(skip_patterns: Optional[Set[str]] = None)`
+
+**Purpose:** Initializes the MIME detection engine (`python-magic`) and sets up skip patterns.
+
+**Default Skip Patterns:** `Instructions`, `.venv`, `venv`, `__pycache__`, `.git`, `.DS_Store`, `.idea`, `.pytest_cache`, `node_modules`, `.github`, `models`, `.env`
+
+**Parameter:** `skip_patterns` overrides the defaults if provided.
+
+---
+
+#### `should_skip(path: str) -> bool`
+
+**Purpose:** Returns `True` if any skip pattern appears anywhere in the path string.
+
+**Algorithm:** Simple substring matching — `any(s in path for s in self.skip_patterns)`.
+
+**Tradeoff:** Substring matching is fast but imprecise (e.g., a file named `modelsummary.txt` would match `models`). For this use case, false positives in skip logic are acceptable.
+
+---
+
+#### `scan_directory(root_path: str) -> List[UniversalResource]`
+
+**Purpose:** Backward-compatible wrapper around `scan()`. Returns just the resource list.
+
+**When to use:** When you only need the file list and don't care about stats/errors.
+
+---
+
+#### `scan(root_path: str, apply_filter: bool = True) -> ScanResult`
+
+**Purpose:** Full DFS traversal with statistics, error tracking, and optional filtering.
+
+**Algorithm:**
+1. Validate `root_path` is a directory
+2. Walk with `os.walk()` (DFS order)
+3. **Prune:** Remove skip-pattern directories from `dirs[:]` in-place (prevents `os.walk` from descending)
+4. For each file: detect MIME type, get size, create `UniversalResource`
+5. Catch `OSError`/`PermissionError` per file and log to `errors`
+
+**Performance Note:** Directory pruning (`dirs[:] = [...]`) is O(n) per directory but prevents the walker from entering massive skip directories like `node_modules/`, which can contain 100k+ files.
+
+**Parameter:** `apply_filter=False` disables all filtering — useful for testing.
+
+---
+
+## `src/template_loader.py` — TemplateLoader
+
+### `TemplateLoader`
+
+#### `__init__(template_dir: str = None)`
+
+**Purpose:** Loads `master_template.md` from the specified directory (or auto-resolves from `../templates/`).
+
+**Behavior:**
+1. Reads the raw template file
+2. Generates `cleaned` version (HTML comments stripped)
+3. Generates `compacted` version (comments stripped + duplicate placeholders collapsed)
+4. If the file is missing, activates **Recovery Mode** with a minimal fallback template
+
+---
+
+#### `clean(template: str) -> str` (static method)
+
+**Purpose:** Strips ALL HTML comments (``) and collapses 3+ consecutive newlines to 2.
+
+**Regex:** `re.sub(r'', '', template, flags=re.DOTALL)` — the `DOTALL` flag ensures multi-line comments are matched.
+
+**Important:** This is the foundation of the "no instruction leakage" guarantee. By stripping every HTML comment, we ensure no `` markers ever reach the model.
+
+---
+
+#### `make_compact(template: str) -> str` (class method)
+
+**Purpose:** Aggressively reduces template size for minimal token usage.
+
+**Additional Operations (beyond `clean`):**
+1. Collapses consecutive `**{{PLACEHOLDER}}**` table rows into a single row
+2. Collapses consecutive `${{VAR}}$` rows
+3. Collapses consecutive `{{CODE_LINE_N}}` placeholders
+
+**Use Case:** When the model's context window is limited and every token counts.
+
+---
+
+#### Properties
+
+| Property | Type | Description |
+|:---------|:-----|:------------|
+| `raw` | `str` | Original, unmodified template content |
+| `cleaned` | `str` | Template with HTML comments stripped |
+| `compacted` | `str` | Aggressively minimized template |
+| `path` | `str` | Absolute path to the template file |
+
+---
+
+## `src/prompt_builder.py` — PromptBuilder
+
+### `PromptBuilder`
+
+#### Class Constants
+
+| Constant | Value |
+|:---------|:------|
+| `MERMAID_CLASSDEF_DEFAULT` | `classDef default fill:#1a1a1a,stroke:#bc13fe,...` |
+| `MERMAID_CLASSDEF_HIGHLIGHT` | `classDef highlight fill:#2a0a3a,stroke:#00f3ff,...` |
+
+These are the **canonical source of truth** for cyberpunk Mermaid styling. Used by both `PromptBuilder` (injected into system prompt) and `MermaidFixer` (auto-injected into output).
+
+---
+
+#### `build(template: str, raw_content: str, is_image: bool = False) -> str` (class method)
+
+**Purpose:** Constructs the complete prompt: system rules + template + source input.
+
+**Structure:**
+```
+[System Rules: Core Directives, Section Rules, Mermaid Rules, Output Rules]
+--- MASTER TEMPLATE START ---
+[Template Markdown]
+--- MASTER TEMPLATE END ---
+SOURCE INPUT TO SYNTHESIZE:
+[Raw Content]
+```
+
+**Parameter `is_image`:** When `True`, the context label changes from "structured data" to "visual architecture", which subtly shifts the model's interpretation of the input.
+
+---
+
+#### `_build_rules(context_label: str) -> str` (class method, internal)
+
+**Purpose:** Generates the complete set of Knowledge Architect rules as a single string.
+
+**Rule Categories:**
+1. **CORE DIRECTIVES** (4 rules): Authorship, Synthesis > Summary, Formatting, Academic Tone
+2. **SECTION-SPECIFIC RULES** (8 sections): Document Record, Core Concepts, Visual Knowledge Graph, Technical Deep Dive, Annotated Glossary, Exam Preparation, Curated Study, Quick Reference, Metacognitive Calibration
+3. **OUTPUT RULES** (3 rules): Clean Markdown only, replace placeholders, generate all 10 sections
+
+**Design Decision:** All rules are in one method rather than spread across multiple files. This makes it trivial to audit, modify, or extend the rule set.
+
+---
+
+## `src/model_engine.py` — MimeClassifier, TextExtractor, StarryEngine
+
+### `MimeClassifier`
+
+**Purpose:** Maps any MIME type to one of 6 processing strategies.
+
+#### `classify(mime_type: str) -> str` (class method)
+
+**Returns** one of: `'image'`, `'pdf'`, `'office'`, `'structured'`, `'text'`, `'binary'`
+
+**Classification Priority:**
+1. Check if MIME is in `IMAGE_TYPES` or starts with `image/` → `'image'`
+2. Check if MIME is in `PDF_TYPES` → `'pdf'`
+3. Check if MIME is in `OFFICE_TYPES` → `'office'`
+4. Check if MIME is in `STRUCTURED_TYPES` → `'structured'`
+5. Check if MIME is in `BINARY_TYPES` or matches binary heuristic → `'binary'`
+6. Default fallback → `'text'` (safest: most unknown types are readable)
+
+**Covered MIME Types:**
+
+| Category | MIME Types |
+|:---------|:-----------|
+| **Image** | jpeg, png, gif, bmp, tiff, webp, svg+xml, heic, heif, x-icon |
+| **PDF** | application/pdf |
+| **Office** | docx, pptx, xlsx, odt, ods, odp, doc, xls, ppt |
+| **Structured** | json, csv, xml, yaml, tab-separated-values |
+| **Text** | plain, html, css, javascript, python, java, c, c++, go, rust, ruby, perl, shell, markdown, rst, tex, latex, diff, patch, log, config |
+| **Binary** | octet-stream, zip, gzip, tar, 7z, rar, jar, exe, mach-binary, sharedlib, wasm, sqlite, audio/*, video/*, font/* |
+
+#### `_is_binary_mime(mime_type: str) -> bool` (static, internal)
+
+**Purpose:** Heuristic for detecting likely binary MIME types not in the explicit set.
+
+**Checks:** `audio/`, `video/`, `font/` prefixes, and keywords like `octet-stream`, `executable`, `archive`, `compressed`.
+
+---
+
+### `TextExtractor`
+
+**Purpose:** Reads content from any file format, gracefully handling encoding issues and size limits.
+
+#### `read_text_file(file_path, max_chars=12000) -> str` (static)
+
+**Encoding Fallback Chain:** UTF-8 → Latin-1 → UTF-8 with error replacement.
+
+**Truncation:** Files exceeding `max_chars` are truncated with a `[...truncated...]` marker.
+
+**Design Decision:** Triple encoding fallback ensures no file crashes the pipeline. Latin-1 accepts any byte sequence (0x00–0xFF), so it never fails. The error replacement encoding is the final safety net.
+
+#### `read_json_file(file_path, max_chars=12000) -> str` (static)
+
+**Purpose:** Parses JSON and pretty-prints it with 2-space indent for model readability.
+
+**Fallback:** Falls back to `read_text_file()` on JSON decode errors.
+
+#### `read_csv_file(file_path, max_rows=100) -> str` (static)
+
+**Purpose:** Reads CSV and formats rows as pipe-delimited text.
+
+**Truncation:** Stops at `max_rows` with a truncation marker.
+
+#### `read_office_file(file_path, max_chars=12000) -> str` (static)
+
+**Purpose:** Extracts text from Office documents (.docx, .pptx, .xlsx) by reading their internal XML files.
+
+**Algorithm:** Office documents are ZIP archives containing XML. This method:
+1. Opens as ZipFile
+2. Finds XML files matching `document`, `slide`, `sheet`, or `content` patterns
+3. Strips XML tags with regex
+4. Joins extracted text
+
+**Limitations:** Cannot read encrypted documents or extract formatting. For encrypted docs, returns a descriptive message instead of crashing.
+
+#### `read_binary_preview(file_path, max_bytes=2000) -> str` (static)
+
+**Purpose:** Generates a metadata summary for binary files.
+
+**Output:** File name, extension, size in bytes, and a prompt asking the model to generate a study guide about the file type itself.
+
+---
+
+### `StarryEngine`
+
+#### `__init__(model_path: str = "google/gemma-3-4b-it")`
+
+**Purpose:** Loads the Gemma 3 model into Apple Silicon unified memory.
+
+**Initialization Steps:**
+1. Call `mlx_lm.load(model_path)` → returns `(model, tokenizer)`
+2. Create `TemplateLoader()` → loads and processes the master template
+3. Store `master_template` (raw) and `_prompt_template` (cleaned)
+
+**Memory:** The Gemma 3 4B model uses ~5 GB of unified memory. The 12B variant needs ~16 GB.
+
+---
+
+#### `process_resource(resource: UniversalResource, on_token=None) -> str`
+
+**Purpose:** Routes a `UniversalResource` to the correct analyzer using `MimeClassifier`.
+
+**Routing Table:**
+
+| Strategy | Analyzer | File Types |
+|:---------|:---------|:-----------|
+| `image` | `_analyze_image()` | JPEG, PNG, GIF, BMP, TIFF, WebP, HEIC |
+| `pdf` | `_analyze_pdf()` | PDF (with OCR fallback) |
+| `office` | `_analyze_office()` | DOCX, PPTX, XLSX, ODT, etc. |
+| `structured` | `_analyze_structured()` | JSON, CSV, XML, YAML |
+| `binary` | `_analyze_binary()` | ZIP, audio, video, fonts, executables |
+| `text` | `_analyze_text()` | Python, Java, C, HTML, CSS, Markdown, shell scripts, etc. |
+
+---
+
+#### `_analyze_image(image_path, on_token=None) -> str`
+
+**Pipeline:** PIL open → RGB convert → multimodal prompt → stream → PostProcessor
+
+---
+
+#### `_analyze_pdf(file_path, on_token=None) -> str`
+
+**Pipeline:** PyMuPDF extract → OCR fallback (if <100 chars) → prompt → stream → PostProcessor
+
+**Performance:** Text capped at 12,000 chars. OCR renders first 2 pages at 150 DPI.
+
+---
+
+#### `_analyze_office(file_path, on_token=None) -> str`
+
+**Pipeline:** TextExtractor.read_office_file() → prompt → stream → PostProcessor
+
+**New in v2.1:** Handles .docx, .pptx, .xlsx, .odt by extracting XML text from the ZIP archive.
+
+---
+
+#### `_analyze_structured(file_path, mime_type, on_token=None) -> str`
+
+**Pipeline:** TextExtractor (JSON/CSV/text fallback) → prompt → stream → PostProcessor
+
+**New in v2.1:** Pretty-prints JSON, formats CSV as pipe-delimited tables.
+
+---
+
+#### `_analyze_binary(file_path, on_token=None) -> str`
+
+**Pipeline:** TextExtractor.read_binary_preview() → prompt → stream → PostProcessor
+
+**New in v2.1:** Instead of crashing on binary files, generates a metadata summary and asks the model to explain the file type.
+
+---
+
+#### `_analyze_text(file_path, on_token=None) -> str`
+
+**Pipeline:** TextExtractor.read_text_file() → prompt → stream → PostProcessor
+
+**Improved in v2.1:** Now uses encoding fallback (UTF-8 → Latin-1 → replace) and caps content at 12,000 characters.
+
+---
+
+## `src/postprocessor.py` — MermaidFixer, OutputCleaner, OutputValidator, PostProcessor
+
+### `MermaidFixer`
+
+**Purpose:** Repairs common Mermaid diagram issues in LLM output.
+
+#### `fix(text: str) -> str` (class method)
+
+**Pipeline:**
+1. `_replace_forbidden_types()` → sequenceDiagram/mindmap/classDiagram → graph TD
+2. `_inject_classdef()` → adds cyberpunk classDef lines if missing
+3. `_remove_inline_styles()` → strips `style NodeID fill:...` directives
+4. `_remove_semicolons()` → strips trailing `;` from mermaid lines
+
+**Regex Pattern for blocks:** `r'```mermaid\n.*?```'` with `re.DOTALL` — matches the entire mermaid code fence.
+
+**classDef Injection Logic:** Only injects if `classDef default` is NOT already present. Finds the diagram type line (e.g., `graph TD`) and inserts classDef on the next line.
+
+---
+
+### `OutputCleaner`
+
+**Purpose:** Removes instruction markers that leak from the template into the output.
+
+#### `clean(text: str) -> str` (class method)
+
+**Leak Patterns Detected:**
+1. `` (HTML comment format)
+2. `[[AI INSTRUCTION]] ...` (bracket format)
+3. `**RULES:** ...` (bold marker)
+4. `**DIAGRAM SELECTION:** ...` (selection marker)
+5. `**BLOCK SELECTION:** ...` (block marker)
+6. `**HARD RULES ...` (hard rules marker)
+7. `{{UPPERCASE_PLACEHOLDER}}` (unfilled placeholders)
+
+---
+
+### `OutputValidator`
+
+**Purpose:** Checks that generated output meets structural requirements.
+
+#### `validate(text: str) -> ValidationResult` (class method)
+
+**Checks Performed:**
+1. All 10 required sections present (case-insensitive search)
+2. Mermaid code fence exists
+3. Exam questions exist (`QUESTION 01` or `QUESTION 1`)
+4. No leaked instruction markers
+5. No unfilled placeholders
+
+**Validity Criteria:** Output is valid if:
+- At most 2 sections are missing AND
+- Mermaid diagram is present AND
+- Exam questions are present
+
+---
+
+### `ValidationResult` (dataclass)
+
+```python
+@dataclass
+class ValidationResult:
+ is_valid: bool
+ sections_found: List[str]
+ sections_missing: List[str]
+ has_mermaid: bool
+ has_exam_questions: bool
+ has_source_archive: bool
+ warnings: List[str]
+```
+
+---
+
+### `PostProcessor`
+
+**Purpose:** Orchestrates the full post-processing pipeline.
+
+#### `process(raw_output: str) -> str` (class method)
+
+**Pipeline:**
+1. `OutputCleaner.clean()` — strip leaked instructions
+2. `MermaidFixer.fix()` — repair diagrams
+3. Whitespace normalization — collapse 3+ newlines
+4. `OutputValidator.validate()` — log warnings (non-blocking)
+
+**Design Decision:** Validation is non-blocking — it logs warnings but does not reject output. This is intentional: a study guide missing 1-2 sections is still valuable. The warnings help with debugging and quality tracking.
+
+---
+
+## `src/formatter.py` — StarryFormatter
+
+### `StarryFormatter`
+
+#### `__init__(current_execution_dir: str)`
+
+**Purpose:** Creates the `Instructions/` output directory.
+
+**Behavior:** Uses `os.makedirs(exist_ok=True)` — idempotent, safe to call multiple times.
+
+---
+
+#### `save_guide(original_filepath: str, content: str, post_process: bool = True) -> str`
+
+**Purpose:** Post-processes and saves a study guide.
+
+**Naming Convention:** `{original_name}_StudyGuide.md` with spaces replaced by underscores.
+
+**Post-Processing:** When `post_process=True` (default), runs `PostProcessor.process()` before writing. This is the **final safety net** — even if the engine produces dirty output, the saved file will be clean.
+
+---
+
+#### `validate_guide(file_path: str) -> ValidationResult`
+
+**Purpose:** Reads a saved guide and runs `OutputValidator.validate()` on it.
+
+**Use Case:** Automated quality checks on previously generated guides.
+
+---
+
+## `main.py` — TUI Pipeline
+
+### TUI Utility Functions
+
+#### `_icon(mime: str) -> str`
+
+Maps MIME type substrings to emoji icons. Falls back to 📦 for unknown types.
+
+#### `_sz(n: int) -> str`
+
+Formats byte counts as human-readable strings (B, KB, MB, GB, TB).
+
+#### `_density(input_bytes: int, output_len: int) -> str`
+
+Calculates the knowledge amplification ratio and renders it as 1-5 colored stars.
+
+#### `_should_skip(path: str) -> bool`
+
+Checks if a path matches any skip pattern. Used in the TUI's Phase 2 to filter resources.
+
+#### `_phase(n: int, title: str, glyph: str)`
+
+Prints a phase header with consistent styling.
+
+### `run()`
+
+**Purpose:** The main pipeline orchestrator.
+
+**4-Phase Flow:**
+1. **Neural Initialization:** Load Gemma 3, init scanner and formatter
+2. **Deep Scan:** Traverse CWD, filter, display resource table
+3. **Knowledge Synthesis:** Process each file with live progress bars and token callbacks
+4. **Mission Report:** Display results table and constellation footer

## III. VISUAL KNOWLEDGE GRAPH
-**DIAGRAM SELECTION:** Choose EXACTLY ONE Mermaid diagram type based on content:
-- Algorithm / Decision Tree → `graph TD`
-- System Architecture → `graph TD` or `flowchart LR`
-- Concept Clustering / Overview → `graph TD`
-- Protocol / Interaction Flow → `flowchart LR`
-- Horizontal Process Flow → `flowchart LR`
-
-**HARD RULES FOR ALL DIAGRAMS:**
-- ONLY use `graph` or `flowchart` (Do NOT use `sequenceDiagram` or `mindmap` as they break styling)
-- Node labels: maximum 5 words, no quotation marks inside labels
-- Node IDs: alphanumeric and underscores only (e.g., `bin_search_node`)
-- MUST include the cyberpunk `classDef` lines shown in the template below
-- Do NOT use per-node `style` directives — use only `classDef`
-- Do NOT add semicolons at end of Mermaid lines
-- Use only valid Mermaid.js v10.x syntax
