# GramPilot Architecture

Welcome to the internal workings of **GramPilot** (formerly GramAddict). This document outlines the radical shift from fixed-state deterministic scripting to our current **Vision-Language-Action (VLA)** architecture that powers our "Full Self-Driving" behavior.

## Core Design Philosophy
We treat the Instagram Android App like a dynamic, partially-observable environment. Instead of maintaining thousands of fragile XPaths, the bot relies on a **Cognitive Stack** to infer intent, learn layouts dynamically, and mathematically avoid detection.

---

## 1. The Telepathic Engine (3-Stage Resolution Cascade)
At the center of UI interactions is the `TelepathicEngine` which resolves semantic intent ("tap the like button") into precise screen coordinates via a strictly enforced performance cascade:
- **Stage 1.5: Deterministic Keyword Fast Path**. Over 90% of interactions are handled by a high-performance string matcher that costs 0 API tokens and executes in `<2ms`.
- **Stage 2: Vector Similarity Engine**. If keywords fail, an Ollama Semantic Embedding of the intent is generated and compared (Cosine Similarity) against cached UI vectors via Qdrant. Highly reliable for semantic synonyms.
- **Stage 3: Agentic Fallback**. The ultimate safety net. If visual confidence drops `<0.82`, it falls back to an OpenRouter LLM (e.g., `gemini-3.1-flash-lite-preview`) which parses the raw XML to structurally guarantee a hit without hallucination.

## 2. Telepathic Memory & Autonomy
When Stage 3 successfully resolves an unknown interaction, the bot records the semantic signature into its positive memory (`telepathic_memory.json`). The next time the bot requires this action, it is instantly resolved via the local cache, guaranteeing that expensive LLM operations are only ever performed once per UI permutation.

## 3. The Cognitive Stack

### ⚖️ Active Inference (Shadow Mode)
Found in `active_inference.py`. Based on the free-energy principle, the bot calculates "Surprise" (prediction errors).
- **Shadow Mode**: Before transitioning screens, the bot predicts the target UI. If it lands somewhere unexpected (a popup), it registers a prediction error, hits "Back", and averts a crash.

### 🛡️ Honeypot Radome & Anti-Trap Sensors
Found in `sensors/honeypot_radome.py`.
- **Topological Traps**: Instagram deploys 1x1 pixel or 0x0 traps to detect bots. The Radome strictly strips these nodes prior to processing.
- **The Interceptor Sentinel**: Detects and purges full-screen invisible `clickable="true"` overlays that act as touch traps (e.g., bounds >= 90% with no content description).
- **Ghost Engagement Guard**: Strips DOM nodes explicitly tagged with `visible-to-user="false"` to prevent triggering Accessibility Hooks.
- **VLM Sanity Guard**: Woven into `telepathic_engine.py`, it sends semantic matches for destructive actions (Like/Follow) through a Vision Language Model step to prevent executing semantic "Bait and Switch" tricks.

### 🧠 Situational Awareness Engine (SAE)
Found in `situational_awareness.py`. Handles autonomous obstacle detection, recovery, and learning without hardcoded rules.
- **3-Layer Modal Fast-Path**: Eliminates LLM hallucination traps for Instagram-internal modals (surveys, rating prompts) via O(1) deterministic structural checks:
  1. **Resource-ID Guard**: Detects internal blocking overlays (e.g., `survey_overlay_container`, `nux_overlay`).
  2. **Dismiss-Button Heuristic**: Cross-validates typical negative actions ("Not Now", "Take Survey") with overlay structures to prevent false positives in post captions.
  3. **Zero-Deception Fallback**: If structural markers fail, falls back to `ScreenMemoryDB` and ultimately the LLM. Structured invariants always override the semantic cache.

### 🦾 Biometric Facade (Gaussian Clicks)
Found in `device_facade.py`.
- Human touches do not follow a flat mathematical uniform grid. The GramPilot simulates genuine **biometric dispersion** using `random.gauss(mu, sigma)`, strictly centering clicks inside a thumb-bias radius (bottom-left skew for right-handers). In tests, this hits a 68% standard deviation precision.

### 💉 Dopamine Engine & Resonance Oracle
Instead of hardcoding limits like `max_likes = 50`, the bot stops interacting based on **simulated boredom**.
- The `ResonanceEngine` calculates the aesthetic score of content.
- The `DopamineEngine` uses this score to modulate pace. High resonance = engagement. Low resonance over multiple posts = early session termination (simulating human fatigue).

## 4. The 100% Autonomy Directive (Zero Hardcoding)
GramPilot is designed as a true agent, not a state-machine script. It operates on **absolute zero hardcoded UI states or edge cases**.
- **No Manual Guards**: Features like `if "row_feed_button_like" not in xml:` or `if state == "ReelsFeed":` are strictly prohibited. The bot must understand the screen via its Vision-Language-Action (VLA) pipeline.
- **No Hand-Holding**: If the LLM makes a mistake (e.g., clicking the wrong button in a DM), the solution is to improve the VLM prompt, the system architecture, or the Visual Critic. We never insert `if is_dm_thread:` hacks.
- **Smart like a human**: The bot navigates by visually confirming targets, detecting obstacles when the UI organically stops responding, and inferring context precisely like a real user scrolling.
