docs: revise architecture audit and roadmap for v2.6.0

[carlos-alm]

Summary

• Revise generated/architecture.md against the actual codebase as it grew from v1.4.0 (5K lines, 12 modules) to v2.6.0 (17,830 lines, 35 modules)
• Add Phase 2.5 (Analysis Expansion) to docs/roadmap/ROADMAP.md documenting 18 modules shipped across v2.0.0-v2.6.0
• Reprioritize all architectural recommendations based on actual growth patterns

Key priority shifts:

• Dual-function anti-pattern across 15 modules is now Bump actions/setup-node from 4 to 6 #1 (was Bump actions/github-script from 7 to 8 #3)
• Parser plugin system dropped from Bump actions/setup-node from 4 to 6 #1 to feat: registry hardening, single-repo MCP, and strategic repositioning #20 (parser.js shrank from 2,215 to 404 lines)
• MCP composability, CLI command objects, and curated API jumped from Medium to High
• 3 new recommendations added: complexity.js decomposition, unified graph model, pagination standardization

Roadmap changes:

• Phase 2.5 documents all features shipped since v1.4.0 that weren't in the original roadmap
• Phase 5.3 (Hybrid Search) marked as completed early during Phase 2.5
• Phase 3 re-prioritized with command/query separation and repository pattern as critical foundation
• Preserves Phase 4 (TypeScript Migration) from docs: add TypeScript migration phase to roadmap #255
• Version updated from 1.4.0 to 2.6.0

Split from #261 — this PR contains only documentation changes.

Test plan

• No code changes — docs only
• Verify all internal links resolve
• Verify phase numbering is consistent throughout

PR Review: Architecture Documentation Revision

Reviewing documentation changes for architecture audit and roadmap revision v2.6.0.

Todo List

• Read and analyze changed documentation files
• Verify claims against actual codebase using codegraph
• Apply 4-phase review methodology
• Check internal links and consistency
• Provide final assessment with rating

Root Cause Analysis

Problem Being Solved: This PR updates architecture documentation and roadmap to reflect actual codebase growth from v1.4.0 (5K lines, 12 modules) to v2.6.0 (17,830 lines, 35 modules). The original architectural analysis is outdated.

Why This Approach: Documentation-only changes split from #261 to focus purely on analysis revision without code modifications. This is appropriate given the scale of changes needed.

Risk Assessment: Documentation changes carry minimal risk but accuracy is critical for future architectural decisions.

Critical Concerns (if any)

None. This is documentation-only with no configuration changes, test modifications, or code alterations.

Verification Against Actual Codebase

I verified key claims against the actual codebase:

✅ File size claims are accurate:

• queries.js: 3,077 lines (claimed 3,110 - close)
• complexity.js: 2,163 lines (matches exactly)
• mcp.js: 1,229 lines (claimed 1,212 - close)
• cli.js: 1,356 lines (claimed 1,285 - close)
• builder.js: 1,195 lines (claimed 1,173 - close)
• embedder.js: 1,113 lines (matches exactly)

✅ Dual-function pattern claims verified:
Found 17 modules with *Data() functions, confirming the architectural anti-pattern analysis across audit.js, batch.js, check.js, cochange.js, communities.js, complexity.js, flow.js, manifesto.js, owners.js, queries.js, structure.js, triage.js, and others.

✅ Module count verified:
Found 35+ source modules in /src, confirming the growth from ~12 to 35 modules.

⚠️ Internal link issues:

• References to docs/roadmap/llm-integration.md exist and the file is present
• Reference to generated/architecture.md uses relative path ../../generated/architecture.md which resolves correctly
• All internal documentation links appear to resolve properly

Quality Assessment

Architecture Analysis Quality

The revised architecture audit demonstrates thorough analysis:

1. Evidence-based priority reordering: The shift from parser plugin system (Bump actions/setup-node from 4 to 6 #1 → feat: registry hardening, single-repo MCP, and strategic repositioning #20) to dual-function pattern elimination (Bump actions/github-script from 7 to 8 #3 → Bump actions/setup-node from 4 to 6 #1) is well-justified by actual codebase evolution
2. Concrete examples: Each recommendation includes specific line counts, file names, and code patterns
3. Growth pattern recognition: Correctly identifies that Phase 2.5 added 18 modules using the same anti-pattern without shared abstractions

Roadmap Updates

The roadmap revisions appropriately:

1. Add Phase 2.5: Documents the 18 modules shipped across v2.0.0-v2.6.0 that weren't in the original roadmap
2. Mark completed features: Hybrid Search (Phase 5.3) correctly marked as completed during Phase 2.5
3. Version alignment: Updated from v1.4.0 to v2.6.0 throughout
4. Priority rebalancing: MCP composability, CLI command objects, and curated API appropriately elevated from Medium to High priority

Documentation Structure

• Clear phase numbering and dependency tracking
• Comprehensive command examples in dogfooding section
• Well-organized priority matrix with reasoning
• Detailed technical specifications for each architectural change

Final Recommendation

• Rating: ⭐⭐⭐⭐☆ (4/5)
• Action: APPROVE
• Reasoning: This is high-quality architectural documentation that accurately reflects the current codebase state. The analysis is thorough, evidence-based, and provides concrete guidance for future development. The priority reordering based on actual growth patterns shows mature architectural thinking. Minor deduction only because some line count claims are approximate rather than exact (though all are very close and within reasonable variance).

The documentation changes are well-researched, accurately reflect the current codebase, and provide valuable guidance for addressing the architectural debt accumulated during rapid feature development.

Greptile Summary

This PR comprehensively revises both the architecture audit and roadmap to reflect the codebase's evolution from v1.4.0 (5K lines, 12 modules) to v2.6.0 (17,830 lines, 35 modules).

Key changes:

• Added Phase 2.5 documenting all features shipped since v1.4.0 that weren't in the original roadmap (complexity metrics, community detection, manifesto, triage, audit, hybrid search, etc.)
• Reprioritized architectural recommendations based on actual growth patterns — dual-function anti-pattern now Bump actions/setup-node from 4 to 6 #1 (was Bump actions/github-script from 7 to 8 #3), parser plugin system dropped to feat: registry hardening, single-repo MCP, and strategic repositioning #20 (was Bump actions/setup-node from 4 to 6 #1) since native Rust engine solved it
• Updated all version numbers from 1.4.0 to 2.6.0 and dates to March 2026
• Marked Phase 5.3 (Hybrid Search) as completed early during Phase 2.5
• Restructured Phase 3 with command/query separation and repository pattern as critical foundation work

The revisions accurately capture how the project evolved organically without addressing the original architectural debt, which was instead replicated across 15+ new modules. All internal references, phase numbering, and cross-links appear consistent.

Confidence Score: 5/5

• This documentation-only PR is completely safe to merge with no risk
• Documentation changes only with no code modifications. All revisions are well-reasoned, internally consistent, and accurately reflect the codebase evolution. Version numbers, phase numbering, and cross-references are consistent throughout both documents.
• No files require special attention
