   Plan

   Observations

   The codebase structure supports binary parsing via goblin for ELF, PE, and Mach-O formats. FoundString in src/types.rs lacks a referenced field, and ContainerInfo needs relocation_targets. Container parsers extract sections, imports, and exports but not relocations. Extraction and classification modules are stubs. Goblin provides relocation APIs: elf::reloc for ELF, pe::relocation for PE, mach::relocation for Mach-O. Tests exist but need relocation-specific cases. Documentation in docs/src/ requires ranking updates.

   Approach

   1. Extend types: Add referenced: Option<bool> to FoundString and relocation_targets: Vec<u64> to ContainerInfo.\n2. Create src/container/relocation.rs for shared utilities.\n3. Implement extract_relocations in each parser, populating relocation_targets.\n4. In src/extraction/mod.rs, add mark_referenced_strings to flag matching strings.\n5. In src/classification/mod.rs, add scoring boost for referenced strings.\n6. Update JSON output in src/output/ to include the flag.\n7. Add unit/integration tests for relocation extraction and flagging.\n8. Document in docs/src/ranking.md and string-extraction.md.

   Reasoning

   I examined the project directory structure to understand the codebase layout. I reviewed the core types in src/types.rs to identify necessary extensions. I analyzed the container parsers in src/container/ (elf.rs, pe.rs, macho.rs) to see existing extraction logic. I checked the empty extraction and classification modules. I searched goblin documentation for relocation parsing capabilities across formats. This confirmed the feasibility of adding relocation-based hinting with minimal changes.

   Proposed File Changes

   📄 src/types.rs ^(MODIFY) 🔗

   Add referenced: Option<bool>, defaulting to None, to the FoundString struct after the source field. Ensure it implements Serialize/Deserialize with #[serde(skip_serializing_if = "Option::is_none")].

   Add relocation_targets: Vec<u64> to the ContainerInfo struct after the exports field. This will store RVAs/virtual addresses referenced by relocations, populated by parsers.

      --body "## Overview
    
    Parse relocation entries from supported binary formats (ELF .rela/.rel, PE relocation table, Mach-O LC_DYLD_INFO) to identify data addresses that are directly referenced by code. Mark extracted strings at these addresses with a \"referenced\" flag and boost their relevance scores.
    
    ## Context
    
    When binaries are compiled with position-independent code (PIE/PIC) or are relocatable, the linker generates relocation entries that map virtual addresses to their actual runtime locations. These relocation entries provide a **high-confidence signal** that specific data addresses (including string literals) are actively used by the code, without requiring expensive disassembly or control-flow analysis.
    
    By parsing these relocation tables, we can:
    - Identify strings that are **definitely** referenced by code (zero false positives)
    - Prioritize these strings in the ranking algorithm
    - Provide this metadata to analysts for focused triage
    - Improve signal-to-noise ratio in stripped binaries where symbol tables are unavailable
    
    This is particularly valuable because relocation data persists even in stripped binaries, making it a reliable source of ground truth about what data the code actually uses.
    
    ## Benefits
    
    - **Zero-cost analysis**: No disassembly or emulation required for this subset
    - **High confidence signal**: Relocation entries are ground truth from the linker
    - **Works on stripped binaries**: Relocation info survives stripping
    - **Format-agnostic approach**: Applicable to ELF, PE, and Mach-O
    - **Improves ranking**: Dramatically reduces false positives in string extraction
    
    ## Technical Details
    
    ### ELF Relocations
    
    ELF binaries contain relocation sections (`.rela.dyn`, `.rela.plt`, `.rel.dyn`, `.rel.plt`) that specify:
    - `r_offset`: Virtual address where the relocation applies
    - `r_info`: Type and symbol index
    - `r_addend`: Constant addend (for RELA-type relocations)
    
    Relevant relocation types:
    - `R_*_RELATIVE`: Adjust for base address (common in PIE)
    - `R_*_GLOB_DAT`: Global offset table entries
    - `R_*_JUMP_SLOT`: Procedure linkage table entries
    - `R_*_64/32`: Direct address references
    
    **Implementation**: Use `goblin::elf::reloc::Reloc` to parse relocation entries and extract target addresses.
    
    ### PE Relocations
    
    PE binaries contain a Base Relocation Table (IMAGE_DIRECTORY_ENTRY_BASERELOC) that groups relocations by 4KB pages:
    - Each entry specifies a page RVA and a list of offsets within that page
    - Type field indicates relocation type (most commonly `IMAGE_REL_BASED_HIGHLOW` or `IMAGE_REL_BASED_DIR64`)
    
    **Implementation**: Parse the `.reloc` section via `goblin::pe::relocation` to identify relocated addresses.
    
    ### Mach-O Relocations
    
    Mach-O binaries use the `LC_DYLD_INFO` or `LC_DYLD_INFO_ONLY` load commands to store compressed relocation data:
    - Rebase opcodes: Adjust pointers for ASLR
    - Binding opcodes: Link to external symbols
    - Lazy binding opcodes: Deferred symbol resolution
    
    **Implementation**: Parse dyld info via `goblin::mach::exports` and process rebase/bind opcodes to extract referenced addresses.
    
    ## Proposed Solution
    
    ### 1. Extend `FoundString` type
    
    Add a `referenced` flag to the `FoundString` struct in `src/types.rs`:
    
    \`\`\`rust
    #[derive(Debug, Clone, Serialize, Deserialize)]
    pub struct FoundString {
        // ... existing fields ...
        
        /// Whether this string is directly referenced by code via relocations
        #[serde(skip_serializing_if = \"Option::is_none\")]
        pub referenced: Option<bool>,
    }
    \`\`\`
    
    ### 2. Add relocation parsing to container parsers
    
    Extend `ContainerInfo` to include relocation data:
    
    \`\`\`rust
    pub struct ContainerInfo {
        // ... existing fields ...
        
        /// Addresses referenced by relocations
        pub relocation_targets: Vec<u64>,
    }
    \`\`\`
    
    Implement relocation parsing in:
    - `src/container/elf.rs`: Parse `.rela.dyn`, `.rela.plt`, `.rel.dyn`, `.rel.plt` sections
    - `src/container/pe.rs`: Parse `.reloc` section (Base Relocation Table)
    - `src/container/macho.rs`: Parse `LC_DYLD_INFO` load command rebase and bind entries
    
    ### 3. Cross-reference strings with relocation targets
    
    During string extraction in `src/extraction/mod.rs`:
    1. Extract all strings as usual
    2. Build a set of relocation target addresses from `ContainerInfo`
    3. For each extracted string, check if its RVA/offset is in the relocation target set
    4. Set `referenced = true` for matches
    
    ### 4. Update scoring algorithm
    
    In `src/classification/mod.rs`, boost the score for strings with `referenced = true`:
    
    \`\`\`rust
    if found_string.referenced == Some(true) {
        score += 50; // Significant boost for code-referenced strings
    }
    \`\`\`
    
    ### 5. Update output formats
    
    Include the `referenced` flag in JSON output and consider adding a visual indicator (e.g., `*` prefix) in human-readable output for referenced strings.
    
    ## Acceptance Criteria
    
    - [ ] `FoundString` struct includes `referenced: Option<bool>` field
    - [ ] `ContainerInfo` includes `relocation_targets: Vec<u64>` field
    - [ ] ELF parser extracts relocation entries from `.rela.*` and `.rel.*` sections
    - [ ] PE parser extracts relocation entries from `.reloc` section
    - [ ] Mach-O parser extracts rebase/bind targets from `LC_DYLD_INFO`
    - [ ] Extraction pipeline cross-references string addresses with relocation targets
    - [ ] Scoring algorithm boosts referenced strings significantly
    - [ ] Unit tests for each relocation parser with test binaries
    - [ ] Integration tests verify referenced strings are correctly flagged
    - [ ] Documentation updated with examples of relocation-based ranking

    - Issue #62: DWARF Debug Information (alternative metadata for symbols)
    - Issue #63: Mach-O Load Command Strings (format-specific extraction)
    
    ## Implementation Notes
    
    - Start with ELF as it has the most straightforward relocation format
    - Consider using `goblin` crate's built-in relocation parsing where available
    - For stripped binaries, this may be the **only** reliable signal about string usage
    - Relocation data can be large in some binaries; consider streaming or filtering to reduce memory usage
    - Not all strings will be referenced (e.g., embedded data, resources, error messages in unused paths)

    I have updated the Implementation Plan to reflect the recent changes in the ticket.

    Previous Plan

    Observations

    The codebase is well-structured with a clear separation of concerns. The container parsers (ELF, PE, Mach-O) are fully implemented and use the goblin library for binary parsing. The FoundString struct in src/types.rs currently has fields for text, encoding, offset, RVA, section, length, tags, score, and source, but lacks a "referenced" flag. The extraction, classification, and ranking modules are currently empty stubs awaiting implementation. The goblin library provides relocation parsing APIs for all three binary formats: goblin::elf::reloc for ELF, goblin::pe::relocation for PE, and goblin::mach::relocation for Mach-O.

    Approach

    Add relocation-based hinting by:

    1. Extending FoundString with a referenced boolean field
    2. Creating a new relocation module to parse and extract relocation target addresses from each binary format
    3. Extending each container parser to extract relocation information
    4. Adding ContainerInfo field to store referenced addresses
    5. Creating address matching logic to mark strings as referenced
    6. Updating the ranking documentation to include the referenced boost (when ranking is implemented)

    This approach is minimal, format-agnostic, and integrates cleanly with the existing architecture without requiring disassembly.

    Reasoning

    I explored the codebase structure by listing directories, reading the core type definitions in src/types.rs, examining all three container parsers (src/container/elf.rs, pe.rs, macho.rs), reviewing the documentation (docs/src/ranking.md, string-extraction.md, architecture.md), checking integration tests, and searching the web for goblin's relocation parsing capabilities. This revealed that the infrastructure is ready for relocation-based hinting with minimal changes needed.

    Proposed File Changes

    📄 src/types.rs ^(MODIFY) 🔗

    Add a referenced boolean field to the FoundString struct (around line 143-163). This field will indicate whether the string's address is referenced by code through relocation entries. Initialize it to false by default. This field should be included in the Serialize/Deserialize traits already present on the struct.
    Add a new field referenced_addresses to the ContainerInfo struct (around line 78-88). This should be a Vec<u64> or HashSet<u64> containing the set of addresses (RVAs or virtual addresses) that are referenced by relocation entries. This will be populated by the container parsers and used later to mark strings as referenced.

    📄 src/container ^(MODIFY) 🔗

    Create a new module file relocation.rs that defines common relocation-related types and utilities. This module should include:

    • A RelocationInfo struct with fields for source address, target address, and relocation type
    • Helper functions for extracting target addresses from relocations
    • Documentation explaining the purpose of relocation-based hinting

    This module will be used by all three format-specific parsers to handle relocations in a consistent way.

    📄 src/container/mod.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/relocation.rs

    Add pub mod relocation; declaration (around line 8, after the existing module declarations for elf, macho, and pe) to expose the new relocation module. Also re-export key types from the relocation module for easier access by other parts of the codebase.

    📄 src/container/elf.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/relocation.rs
    • 📄 src/types.rs ^(MODIFY)

    Add a new private method extract_relocations to the ElfParser implementation (around line 317, after the extract_exports method). This method should:

    • Use goblin::elf::reloc::RelocSection to iterate through relocation sections (.rela.dyn, .rela.plt, .rel.dyn, .rel.plt)
    • Extract target addresses from each relocation entry using the r_offset field
    • Handle both RELA (with addend) and REL (without addend) relocation types
    • Return a Vec<u64> of referenced addresses
    • Include error handling for malformed relocation data

    Then modify the parse method in the ContainerParser trait implementation (around line 324) to call extract_relocations and populate the referenced_addresses field in the returned ContainerInfo.

    📄 src/container/pe.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/relocation.rs
    • 📄 src/types.rs ^(MODIFY)

    Add a new private method extract_relocations to the PeParser implementation (around line 121, after the extract_exports method). This method should:

    • Access the base relocation table through pe.header.optional_header data directories
    • Parse base relocation blocks manually (goblin provides the directory location but not a high-level iterator)
    • Extract target RVAs from each relocation entry by combining the block's page RVA with individual entry offsets
    • Handle different relocation types (IMAGE_REL_BASED_HIGHLOW for 32-bit, IMAGE_REL_BASED_DIR64 for 64-bit)
    • Return a Vec<u64> of referenced RVAs
    • Include error handling for invalid relocation data

    Then modify the parse method in the ContainerParser trait implementation (around line 128) to call extract_relocations and populate the referenced_addresses field in the returned ContainerInfo.

    📄 src/container/macho.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/relocation.rs
    • 📄 src/types.rs ^(MODIFY)

    Add a new private method extract_relocations to the MachoParser implementation (around line 253, after the is_writable_section method). This method should:

    • Iterate through segments and their sections to find relocation entries
    • Use goblin::mach::relocation::RelocationInfo to parse relocation data
    • For LC_DYLD_INFO load commands, parse the rebase and binding information to identify referenced addresses
    • Extract target addresses from relocation entries, adjusting for segment base addresses
    • Return a Vec<u64> of referenced virtual addresses
    • Include error handling for malformed relocation data

    Then modify the parse_single_macho method (around line 181) to call extract_relocations and populate the referenced_addresses field in the returned ContainerInfo.

    📄 src/extraction/mod.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/types.rs ^(MODIFY)

    Add a public function mark_referenced_strings that takes a mutable slice of FoundString and a reference to ContainerInfo. This function should:

    • Extract the referenced_addresses from ContainerInfo
    • For each string in the slice, check if its RVA (or offset if RVA is not available) matches any address in the referenced set
    • Set the referenced field to true for matching strings
    • Use efficient lookup (e.g., convert Vec to HashSet if not already)
    • Include documentation explaining the purpose and usage

    This function will be called after string extraction to mark strings that are referenced by code through relocations.

    📄 docs/src/ranking.md ^(MODIFY) 🔗

    Add a new section titled "Relocation-Based Boost" after the "Semantic Boost" section (around line 147). This section should document:

    • The purpose of relocation-based hinting (identifying strings referenced by code)
    • The boost value for referenced strings (suggest +15 points, similar to file paths)
    • An explanation that this is a zero-cost signal for stripped binaries with relocation info
    • A note that no disassembly is required for this subset of strings
    • Example code showing how the boost is applied in the scoring algorithm

    Also update the "Complete Scoring Implementation" section (around line 259) to include the relocation boost in the score calculation formula.

    📄 tests/integration_elf.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/elf.rs ^(MODIFY)
    • 📄 src/types.rs ^(MODIFY)

    Add a new test function test_elf_relocation_extraction (around line 448, after the existing tests). This test should:

    • Load the ELF test fixture from tests/fixtures/test_binary_elf
    • Parse it using ElfParser
    • Verify that container_info.referenced_addresses is not empty (the test binary should have relocations)
    • Print the number of relocations found for debugging
    • Assert that at least some relocations were extracted
    • Include comments explaining what relocations are expected in the test binary

    This test validates that the ELF relocation extraction is working correctly.

    📄 tests/integration_pe.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/pe.rs ^(MODIFY)
    • 📄 src/types.rs ^(MODIFY)

    Add a new test function test_pe_relocation_extraction (around line 118, after the existing tests). This test should:

    • Load the PE test fixture from tests/fixtures/test_binary_pe.exe
    • Parse it using PeParser
    • Check if container_info.referenced_addresses contains any entries
    • Print the number of relocations found (PE executables may or may not have base relocations depending on compilation flags)
    • Include a comment noting that PE executables compiled with /FIXED may not have relocations
    • Assert that the parsing completes successfully even if no relocations are found

    This test validates that the PE relocation extraction handles both cases (with and without relocations) gracefully.

    📄 tests/integration_macho.rs ^(MODIFY) 🔗

    
    

    References

    • 📄 src/container/macho.rs ^(MODIFY)
    • 📄 src/types.rs ^(MODIFY)

    Add a new test function test_macho_relocation_extraction (around line 111, after the existing tests). This test should:

    • Load the Mach-O test fixture from tests/fixtures/test_binary_macho
    • Parse it using MachoParser
    • Verify that container_info.referenced_addresses is populated
    • Print the number of relocations found for debugging
    • Assert that at least some relocations were extracted (Mach-O binaries typically have dyld info)
    • Include comments explaining the expected relocation sources (LC_DYLD_INFO, section relocations)

    This test validates that the Mach-O relocation extraction is working correctly.

    I have created the following plan after thorough exploration and analysis of the codebase. Follow the below plan verbatim. Trust the files and references. Do not re-verify what's written in the plan. Explore only when absolutely necessary. First implement all the proposed file changes and then I'll review all the changes together at the end.

    ## Proposed File Changes
    
    ### src/types.rs(MODIFY)
    
    Add a `referenced` boolean field to the `FoundString` struct (around line 143-163). This field will indicate whether the string's address is referenced by code through relocation entries. Initialize it to `false` by default. This field should be included in the Serialize/Deserialize traits already present on the struct.
    Add a new field `referenced_addresses` to the `ContainerInfo` struct (around line 78-88). This should be a `Vec<u64>` or `HashSet<u64>` containing the set of addresses (RVAs or virtual addresses) that are referenced by relocation entries. This will be populated by the container parsers and used later to mark strings as referenced.
    
    ### src/container(MODIFY)
    
    Create a new module file `relocation.rs` that defines common relocation-related types and utilities. This module should include:
    - A `RelocationInfo` struct with fields for source address, target address, and relocation type
    - Helper functions for extracting target addresses from relocations
    - Documentation explaining the purpose of relocation-based hinting
    
    This module will be used by all three format-specific parsers to handle relocations in a consistent way.
    
    ### src/container/mod.rs(MODIFY)
    
    References: 
    
    - src/container/relocation.rs
    
    Add `pub mod relocation;` declaration (around line 8, after the existing module declarations for elf, macho, and pe) to expose the new relocation module. Also re-export key types from the relocation module for easier access by other parts of the codebase.
    
    ### src/container/elf.rs(MODIFY)
    
    References: 
    
    - src/container/relocation.rs
    - src/types.rs(MODIFY)
    
    Add a new private method `extract_relocations` to the `ElfParser` implementation (around line 317, after the `extract_exports` method). This method should:
    - Use `goblin::elf::reloc::RelocSection` to iterate through relocation sections (.rela.dyn, .rela.plt, .rel.dyn, .rel.plt)
    - Extract target addresses from each relocation entry using the `r_offset` field
    - Handle both RELA (with addend) and REL (without addend) relocation types
    - Return a `Vec<u64>` of referenced addresses
    - Include error handling for malformed relocation data
    
    Then modify the `parse` method in the `ContainerParser` trait implementation (around line 324) to call `extract_relocations` and populate the `referenced_addresses` field in the returned `ContainerInfo`.
    
    ### src/container/pe.rs(MODIFY)
    
    References: 
    
    - src/container/relocation.rs
    - src/types.rs(MODIFY)
    
    Add a new private method `extract_relocations` to the `PeParser` implementation (around line 121, after the `extract_exports` method). This method should:
    - Access the base relocation table through `pe.header.optional_header` data directories
    - Parse base relocation blocks manually (goblin provides the directory location but not a high-level iterator)
    - Extract target RVAs from each relocation entry by combining the block's page RVA with individual entry offsets
    - Handle different relocation types (IMAGE_REL_BASED_HIGHLOW for 32-bit, IMAGE_REL_BASED_DIR64 for 64-bit)
    - Return a `Vec<u64>` of referenced RVAs
    - Include error handling for invalid relocation data
    
    Then modify the `parse` method in the `ContainerParser` trait implementation (around line 128) to call `extract_relocations` and populate the `referenced_addresses` field in the returned `ContainerInfo`.
    
    ### src/container/macho.rs(MODIFY)
    
    References: 
    
    - src/container/relocation.rs
    - src/types.rs(MODIFY)
    
    Add a new private method `extract_relocations` to the `MachoParser` implementation (around line 253, after the `is_writable_section` method). This method should:
    - Iterate through segments and their sections to find relocation entries
    - Use `goblin::mach::relocation::RelocationInfo` to parse relocation data
    - For LC_DYLD_INFO load commands, parse the rebase and binding information to identify referenced addresses
    - Extract target addresses from relocation entries, adjusting for segment base addresses
    - Return a `Vec<u64>` of referenced virtual addresses
    - Include error handling for malformed relocation data
    
    Then modify the `parse_single_macho` method (around line 181) to call `extract_relocations` and populate the `referenced_addresses` field in the returned `ContainerInfo`.
    
    ### src/extraction/mod.rs(MODIFY)
    
    References: 
    
    - src/types.rs(MODIFY)
    
    Add a public function `mark_referenced_strings` that takes a mutable slice of `FoundString` and a reference to `ContainerInfo`. This function should:
    - Extract the `referenced_addresses` from `ContainerInfo`
    - For each string in the slice, check if its RVA (or offset if RVA is not available) matches any address in the referenced set
    - Set the `referenced` field to `true` for matching strings
    - Use efficient lookup (e.g., convert Vec to HashSet if not already)
    - Include documentation explaining the purpose and usage
    
    This function will be called after string extraction to mark strings that are referenced by code through relocations.
    
    ### docs/src/ranking.md(MODIFY)
    
    Add a new section titled "Relocation-Based Boost" after the "Semantic Boost" section (around line 147). This section should document:
    - The purpose of relocation-based hinting (identifying strings referenced by code)
    - The boost value for referenced strings (suggest +15 points, similar to file paths)
    - An explanation that this is a zero-cost signal for stripped binaries with relocation info
    - A note that no disassembly is required for this subset of strings
    - Example code showing how the boost is applied in the scoring algorithm
    
    Also update the "Complete Scoring Implementation" section (around line 259) to include the relocation boost in the score calculation formula.
    
    ### tests/integration_elf.rs(MODIFY)
    
    References: 
    
    - src/container/elf.rs(MODIFY)
    - src/types.rs(MODIFY)
    
    Add a new test function `test_elf_relocation_extraction` (around line 448, after the existing tests). This test should:
    - Load the ELF test fixture from `tests/fixtures/test_binary_elf`
    - Parse it using `ElfParser`
    - Verify that `container_info.referenced_addresses` is not empty (the test binary should have relocations)
    - Print the number of relocations found for debugging
    - Assert that at least some relocations were extracted
    - Include comments explaining what relocations are expected in the test binary
    
    This test validates that the ELF relocation extraction is working correctly.
    
    ### tests/integration_pe.rs(MODIFY)
    
    References: 
    
    - src/container/pe.rs(MODIFY)
    - src/types.rs(MODIFY)
    
    Add a new test function `test_pe_relocation_extraction` (around line 118, after the existing tests). This test should:
    - Load the PE test fixture from `tests/fixtures/test_binary_pe.exe`
    - Parse it using `PeParser`
    - Check if `container_info.referenced_addresses` contains any entries
    - Print the number of relocations found (PE executables may or may not have base relocations depending on compilation flags)
    - Include a comment noting that PE executables compiled with /FIXED may not have relocations
    - Assert that the parsing completes successfully even if no relocations are found
    
    This test validates that the PE relocation extraction handles both cases (with and without relocations) gracefully.
    
    ### tests/integration_macho.rs(MODIFY)
    
    References: 
    
    - src/container/macho.rs(MODIFY)
    - src/types.rs(MODIFY)
    
    Add a new test function `test_macho_relocation_extraction` (around line 111, after the existing tests). This test should:
    - Load the Mach-O test fixture from `tests/fixtures/test_binary_macho`
    - Parse it using `MachoParser`
    - Verify that `container_info.referenced_addresses` is populated
    - Print the number of relocations found for debugging
    - Assert that at least some relocations were extracted (Mach-O binaries typically have dyld info)
    - Include comments explaining the expected relocation sources (LC_DYLD_INFO, section relocations)
    
    This test validates that the Mach-O relocation extraction is working correctly.

    New Plan

    Observations

    The codebase structure supports binary parsing via goblin for ELF, PE, and Mach-O formats. FoundString in src/types.rs lacks a referenced field, and ContainerInfo needs relocation_targets. Container parsers extract sections, imports, and exports but not relocations. Extraction and classification modules are stubs. Goblin provides relocation APIs: elf::reloc for ELF, pe::relocation for PE, mach::relocation for Mach-O. Tests exist but need relocation-specific cases. Documentation in docs/src/ requires ranking updates.

    Approach

    1. Extend types: Add referenced: Option<bool> to FoundString and relocation_targets: Vec<u64> to ContainerInfo.\n2. Create src/container/relocation.rs for shared utilities.\n3. Implement extract_relocations in each parser, populating relocation_targets.\n4. In src/extraction/mod.rs, add mark_referenced_strings to flag matching strings.\n5. In src/classification/mod.rs, add scoring boost for referenced strings.\n6. Update JSON output in src/output/ to include the flag.\n7. Add unit/integration tests for relocation extraction and flagging.\n8. Document in docs/src/ranking.md and string-extraction.md.

    Reasoning

    I examined the project directory structure to understand the codebase layout. I reviewed the core types in src/types.rs to identify necessary extensions. I analyzed the container parsers in src/container/ (elf.rs, pe.rs, macho.rs) to see existing extraction logic. I checked the empty extraction and classification modules. I searched goblin documentation for relocation parsing capabilities across formats. This confirmed the feasibility of adding relocation-based hinting with minimal changes.

    Proposed File Changes
