…folder Move COMPETITIVE_ANALYSIS.md into generated/competitive/ and add a comprehensive feature-by-feature comparison against joernio/joern (our #1-ranked competitor). Covers parsing, graph model, query language, performance, installation, AI/MCP integration, security analysis, developer productivity, and ecosystem across 100+ individual features. Update FOUNDATION.md reference to the new path.
Impact: 12 functions changed, 28 affected
README.md and docs/roadmap/BACKLOG.md still referenced the old path at generated/COMPETITIVE_ANALYSIS.md after the file was moved to generated/competitive/COMPETITIVE_ANALYSIS.md in #260.
Append a new "Joern-Inspired Feature Candidates" section to the Joern competitive deep-dive. Lists 11 actionable features extracted from Parsing & Language Support, Graph Model & Analysis Depth, and Query Language & Interface sections — assessed with the same tier/grading system used in BACKLOG.md (zero-dep, foundation-aligned, problem-fit, breaking). Tier 1 non-breaking: call-chain slicing, type-informed resolution, error-tolerant parsing, regex filtering, Kotlin, Swift, script execution. Tier 1 breaking: expanded node/edge types, intraprocedural CFG, stored AST. Not adopted: 9 features with FOUNDATION.md reasoning. Cross-references BACKLOG IDs 14 and 7.
Comprehensive comparison across 10 dimensions: parsing (32 vs 11 languages), graph model (CFG/DFG/type inference vs complexity/roles/ communities), search (similarity/chunking vs RRF hybrid), security (147 rules vs none), queries (90 tools vs 21 + compound commands), performance (cold start vs incremental), install, MCP integration, developer productivity, and ecosystem. Feature candidates section covers all comparison sections: - Tier 1 non-breaking (10): MCP presets, AST chunking, code similarity, git blame/symbol history, remote repo indexing, config wizard, Kotlin, Swift, Bash, Scala language support - Tier 1 breaking (1): export map per module - Tier 2 (2): interactive HTML viz, multiple embedding backends - Tier 3 (2): OWASP patterns, SBOM generation - Not adopted (10): taint, type inference, SPARQL/RDF, CCG, in-memory arch, 90-tool surface, browser WASM, Forgemax, LSP, license scanning - Cross-references to BACKLOG IDs 7, 8, 10, 14 and Joern candidates J4, J5, J8, J9

Implements feature N11 from the Narsil competitive analysis. The new command provides a focused export map showing which symbols a file exports and who calls each one, filling the gap between `explain` (public/internal split without consumers) and `where --file` (just export names). Adds exportsData/fileExports to queries.js, CLI command, MCP tool, batch support, programmatic API, and integration tests. Impact: 7 functions changed, 15 affected

Phase 1: Root Cause Analysis ✅Problem Being Solved: This PR implements feature N11 from the competitive analysis against Narsil-MCP. The specific gap identified is that the existing Why This Approach: The implementation follows established patterns in the codebase:

The scoped_rebuild tool is not mentioned in the PR description and appears to be a separate feature bundled into this PR. Additionally, it calls buildGraph with scope and noReverseDeps options that don't exist in builder.js. This feature has no test coverage.

Calling buildGraph with scope and noReverseDeps options that aren't implemented. The builder.js file doesn't support these options (check: grep "opts.scope\|opts.noReverseDeps" src/builder.js returns no matches).
There was a problem hiding this comment.
Fixed in 651ddb2. Removed the leaked scoped_rebuild handler and its buildGraph call with non-existent options.
Extract purgeFilesFromGraph() from the inline deletion cascade in buildGraph() for reuse. Add opts.scope and opts.noReverseDeps to buildGraph() so agents can surgically rebuild only their changed files without nuking other agents' graph state. - `--scope <files...>` on `build` skips collectFiles/getChangedFiles - `--no-reverse-deps` skips reverse-dep cascade (safe when exports unchanged) - New `scoped_rebuild` MCP tool for multi-agent orchestration - purgeFilesFromGraph exported from programmatic API - Unit tests for purge function, integration tests for scoped rebuild - Documented agent-level rollback workflow in titan-paradigm.md Impact: 3 functions changed, 20 affected
