+# PE Metadata Expansion (v0.6.0)
+
+IOCX v0.6.0 introduces a deterministic, static metadata extraction layer for Portable Executable (PE) files.
+This feature expands IOCX’s visibility into binary structure while maintaining strict security guarantees:
+
+- No dynamic analysis
+- No unpacking or emulation
+- No network access
+- No heavy dependencies
+- Fully deterministic and offline
+
+This metadata is used to provide analysts with richer context and to support future heuristic layers (v0.7.0).
+
+## What IOCX Extracts
+
+### 1. Import Table
+
+IOCX extracts:
+
+- DLL names
+- Imported functions
+- Ordinal imports
+- Delayed imports
+- Bound imports
+
+This information helps analysts understand API usage and identify unusual import patterns.
+
+### 2. Export Table
+
+IOCX extracts:
+
+- Exported function names
+- Ordinals
+- Forwarded exports
+
+This is useful for triaging DLLs and identifying suspicious export structures.
+
+### 3. Resource Directory
+
+IOCX extracts:
+
+- Resource types (icons, dialogs, version info, RCDATA)
+- Resource sizes
+- Resource entropy
+- Language codes (mapped to region-locale)
+
+High‑entropy resources may indicate embedded payloads or obfuscation.
+
+> Language codes are mapped to human‑readable locale identifiers using a minimal, safe lookup table. Only well‑defined primary language IDs and a small set of explicit region codes are resolved; ambiguous or non‑standard values are returned as "unknown" to avoid misclassification.
+
+### 4. Extended PE Metadata
+
+IOCX surfaces:
+
+- Timestamp
+- Subsystem
+- Machine type
+- Characteristics flags
+- Optional header fields
+- Entry point
+- Image base
+- Section alignment
+- Compiler/toolchain hints
+- Digital signature presence (raw only)
+- TLS directory (raw only)
+
+This metadata provides a structural overview of the binary without making behavioural claims.
+
+### Security Considerations
+
+- All analysis is read‑only and non‑invasive
+- No code execution occurs at any stage
+- All parsing is wrapped in defensive exception handling
+- No external lookups or network calls are performed
+- All entropy and size calculations are deterministic
+
+This ensures IOCX remains safe to use on untrusted or malicious binaries.
+
+### Relationship to v0.7.0
+
+v0.6.0 is descriptive only.
+It extracts facts but does not interpret them.
+
+Heuristics such as:
+
+- packer detection
+- anti‑debug detection
+- TLS callback analysis
+- import anomaly scoring
+- signature anomaly detection
+- control‑flow hints
+
+are explicitly reserved for v0.7.0, which will build on the metadata introduced here.

+# IOCX PE Analysis Pipeline
+
+IOCX includes a deterministic, static, offline analysis pipeline for Portable Executable (PE) files.
+The pipeline is designed to safely process untrusted binaries without executing them, unpacking them, or performing any dynamic analysis.
+
+This document describes the full PE pipeline as of v0.6.0, including:
+
+- PE parsing
+- metadata extraction
+- obfuscation heuristics
+- deep metadata analysis
+- IOC detection
+
+It also outlines how future versions (v0.7.0+) will extend this pipeline with behavioural heuristics.
+
+## 1. Pipeline Overview
+
+The IOCX PE pipeline consists of the following ordered stages:
+
+- File Type Detection
+- PE Parsing
+- Core Metadata Extraction
+- String Extraction
+- Obfuscation Heuristics (v0.5.0)
+- PE Metadata Expansion (v0.6.0)
+- IOC Detection
+- Output Assembly
+
+Each stage is deterministic, offline, and safe to run on malicious or malformed binaries.

+
+## 2. File Type Detection
+
+IOCX uses signature‑based detection (via python-magic) to determine whether a file is a PE.
+
+- No execution
+- No sandboxing
+- No heuristics
+- Purely structural detection
+
+If the file is not a PE, the PE pipeline is skipped.
+
+## 3. PE Parsing
+
+IOCX uses pefile to parse the binary safely:
+
+- DOS header
+- NT headers
+- Optional header
+- Section table
+- Data directories
+
+All parsing is wrapped in defensive exception handling to prevent crashes on malformed samples.
+
+No dynamic loading or execution occurs.
+
+## 4. Core Metadata Extraction
+
+The engine extracts a minimal set of metadata used by downstream components:
+
+- section names
+- section sizes
+- virtual vs raw size
+- entry point
+- timestamp
+- machine type
+- characteristics flags
+
+This metadata is passed to both the obfuscation heuristics (v0.5.0) and the deep metadata module (v0.6.0).
+
+## 5. String Extraction
+
+IOCX extracts printable ASCII and UTF‑16LE strings from:
+
+- `.text`
+- `.rdata`
+- `.data`
+- entire file (fallback)
+
+Strings are used by:
+
+- obfuscation heuristics
+- IOC detectors
+- future anti‑debug heuristics (v0.7.0)
+
+Extraction is deterministic and bounded.
+
+## 6. Obfuscation Heuristics (v0.5.0)
+
+Introduced in v0.5.0, this module provides lightweight static hints about potential packing or obfuscation.
+
+Heuristics include:
+
+- suspicious section names (.upx, .aspack, .mpress, etc.)
+- high‑entropy sections
+- abnormal section layout
+- basic string‑obfuscation patterns
+
+### Output
+
+Each heuristic emits a structured Detection object:
+
+```json
+{
+  "type": "obfuscation_hint",
+  "value": "high_entropy_section",
+  "metadata": {
+    "section": ".upx0",
+    "entropy": 7.89,
+    "threshold": 7.2
+  }
+}
+```
+
+These hints are contextual, not behavioural.
+
+## 7. PE Metadata Expansion (v0.6.0)
+
+v0.6.0 introduces a comprehensive metadata extraction layer that surfaces rich PE structural information.
+
+This module is descriptive only — no scoring, no heuristics, no packer detection.
+
+### 7.1 Import Table Extraction
+
+Extracts:
+
+- DLL names
+- imported functions
+- ordinals
+- delayed imports
+- bound imports
+
+### 7.2 Export Table Extraction
+
+Extracts:
+
+- exported names
+- ordinals
+- forwarded exports
+
+### 7.3 Resource Directory Extraction
+
+Extracts:
+
+- resource types (ICON, VERSION, RCDATA, etc.)
+- resource sizes
+- resource entropy
+- language codes and region-locale mapping
+
+### 7.4 TLS Directory (Raw Only)
+
+Extracts:
+
+- start/end addresses
+- callback table pointer
+- No heuristics are applied in v0.6.0.
+
+### 7.5 Extended Header Metadata
+
+Extracts:
+
+- timestamp
+- subsystem
+- machine type
+- characteristics
+- entry point
+- image base
+- section alignment
+- compiler/toolchain hints
+- digital signature presence (raw only)
+
+**Output**
+
+Metadata is returned as structured Detection objects of type `pe_metadata`.
+
+## 8. IOC Detection
+
+After metadata and heuristics are complete, IOCX runs its IOC detectors:
+
+- file hashes
+- suspicious strings
+- URLs
+- IPs
+- domains
+- registry paths
+- file paths
+- email addresses
+- cryptographic constants
+- malware‑family‑specific patterns
+
+Detectors operate on:
+
+- raw bytes
+- extracted strings
+- metadata
+- section data
+
+This stage is deterministic and purely static.
+
+## 9. Output Assembly
+
+The engine merges:
+
+- obfuscation hints
+- PE metadata
+- IOC detections
+
+into a single structured JSON output.
+
+### Example
+
+```json
+{
+  "detections": [
+    { "type": "pe_metadata", "value": "import", ... },
+    { "type": "obfuscation_hint", "value": "high_entropy_section", ... },
+    { "type": "ioc", "value": "url", ... }
+  ]
+}
+```
+
+No network access, no external lookups, no dynamic behaviour.
+
+## 10. Security Model
+
+The PE pipeline is designed to be safe for untrusted input:
+
+- no execution
+- no unpacking
+- no emulation
+- no dynamic imports
+- no network calls

+The diagram shows a single forward path from input to output. The analysis stages sit in the middle of the pipeline, but whether they contribute to the final output depends entirely on the selected analysis level.
+
+The pipeline always performs metadata extraction, string extraction, IOC detection, and result assembly. The analysis level determines which additional stages contribute data to the final output. Basic analysis includes only section layout and entropy. Deep analysis adds obfuscation heuristics that rely on both section information and extracted text. Full analysis adds the extended module, which uses the PE object, metadata, and combined text to produce richer structural insights. IOC detection always runs, and the final JSON includes core metadata plus whichever analysis results were enabled.

-The diagram shows a single forward path from input to output. The analysis stages sit in the middle of the pipeline, but whether they contribute to the final output depends entirely on the selected analysis level.
-
-The pipeline always performs metadata extraction, string extraction, IOC detection, and result assembly. The analysis level determines which additional stages contribute data to the final output. Basic analysis includes only section layout and entropy. Deep analysis adds obfuscation heuristics that rely on both section information and extracted text. Full analysis adds the extended module, which uses the PE object, metadata, and combined text to produce richer structural insights. IOC detection always runs, and the final JSON includes core metadata plus whichever analysis results were enabled.
+The pipeline is structured as a straight, deterministic sequence of stages, but only some of them contribute data depending on the selected analysis level. File‑type detection, PE parsing, unified core metadata extraction, string extraction, IOC detection, and JSON assembly always run. Section‑level analysis, obfuscation heuristics, and the extended metadata summary are conditional: basic analysis includes only section layout and entropy; deep analysis adds obfuscation heuristics; full analysis adds the extended metadata summary, which incorporates core metadata, strings, and obfuscation hints into a richer structural view. The final output merges the always‑present core metadata and IOC detections with whichever analysis components were enabled.

 ## Version Highlights
 
+### v0.6.0 — Stable Output Schema, Deterministic PE Metadata, Contract‑Safe Analysis Levels
+
+- Introduced a fully stable JSON schema across all analysis levels
+- Added strict structural guarantees for `iocs`, `metadata`, and `analysis` blocks
+- Normalised PE metadata fields for deterministic output (headers, TLS, optional header, signatures)
+- Ensured **all IOC categories always exist** (empty arrays when no matches)
+- Formalised analysis‑level behaviour:
+  - core behaviour → no analysis block
+  - basic → section layout + entropy
+  - deep → adds obfuscation heuristics

 ### v0.5.0 — Analysis Levels, PE Section Analysis, Obfuscation Hints

 Static analysis ensures **safety**, **determinism**, and **CI‑friendly operation**. No sandboxing, no execution, and no risk of triggering malware behaviour.
 
+## Output Schema (v0.6.0)
+
+IOCX v0.6.0 defines a stable, deterministic JSON schema designed for DFIR, SOC automation, and threat‑intel pipelines. The schema is intentionally simple, predictable, and safe for long‑term integrations.
+
+The top‑level structure contains three blocks:
+
+- `iocs` — extracted indicators
+- `metadata` — structural information about the artifact
+- `analysis` — optional deeper inspection depending on analysis level
+
+This structure is identical across all input types, with PE‑specific fields populated only when applicable.
+
+### IOC Categories
+
+The `iocs` block always contains the same keys, regardless of analysis level:
+
+- `urls`
+- `domains`
+- `ips`
+- `hashes`
+- `emails`
+- `filepaths`
+- `base64`
+- `crypto.btc`
+- `crypto.eth`
+
+Each category is always an array. Empty categories are returned as empty arrays to ensure predictable downstream parsing.
+
+### Metadata Categories
+
+The metadata block contains structural information about the file. For PE files, this includes:
+
+- Imports and import details
+- Sections
+- Resources and resource strings
+- TLS directory
+- Header and optional header
+- Rich header
+- Signatures
+
+These fields are always present, even when empty. Metadata is **independent of analysis level** and is always returned in full.
+
+### Analysis Levels
+
+The `analysis` block is the only part of the schema that changes based on the selected analysis level.
+
+- **basic** — section layout + entropy
+- **deep** — adds obfuscation heuristics
+- **full** — adds extended metadata summaries
+
+This tiered design allows users to trade off performance vs. depth without changing their downstream parsing logic.
+
+### Deterministic Output
+
+IOCX v0.6.0 guarantees:
+
+- Stable keys
+- Stable types
+- No volatile values in minimal modes
+- Deterministic behaviour across runs and platforms
+
+This makes IOCX safe for SIEM/SOAR ingestion, CI/CD pipelines, and large‑scale batch processing.
+
+### Schema stability
+
+IOCX guarantees a stable JSON schema, not a guaranteed ordering of keys within objects. JSON objects are defined as unordered maps, so consumers should rely on field presence and structure rather than positional ordering. All fields, types, and structural relationships remain consistent across versions, even if internal key order changes.
