Implements complete Spec Layer (Spectr) for SIN-Code with all 5 phases: PHASE 1 (Spectr - Core Backbone): - internal/spec/types.go: Core Spec, SpecKind, SpecStatus, SpecCollection, DependencyGraph types - internal/spec/validate.go: Comprehensive validation rules (fields, markdown, deps, cycles) - internal/spec/merge.go: Three-way merge with field-level conflict resolution - cmd/sin-code/spec_cmd.go: CLI commands (init, validate, create, archive, list, show, merge) PHASE 2 (SpecD - Compiler): - internal/spec/compiler.go: Dependency graph building, topological sort (Kahn's algorithm) - Cycle detection, metadata computation (hash, depth), compilation results PHASE 3 (SDLC - Quality Gates): - internal/spec/gates.go: Gate framework with built-in gates - TokenBudgetGate, MarkdownSyntaxGate, DependenciesGate, RequiredFieldsGate, StatusGate - VerificationContext, GateRegistry for managing and running gates PHASE 4 (MetaSpec - Token Optimization): - internal/spec/metaspec.go: Spec indexing, full-text search, fuzzy matching - TokenBudgeter for intelligent allocation (proportional, priority-based) - Smart selection by budget, namespace, kind, status PHASE 5 (SpecKit - Chat Integration): - internal/spec/speckit.go: Slash-commands for chat (/spec, /goal, /verify, /compile, /budget, /search, /deps) - CommandContext, SlashCommand registry - Interactive spec exploration within agent loop SUPPORTING FILES: - internal/spec/doc.go: Package documentation - internal/spec/IMPLEMENTATION.md: Complete usage guide and examples - internal/spec/examples_test.go: Comprehensive test patterns and workflows KEY FEATURES: ✓ 100% deterministic (no LLM calls) ✓ Markdown-based specs ✓ Immutable spec semantics ✓ Non-breaking to existing Agent Loop ✓ Full dependency graph support ✓ Quality gate framework ✓ Token budget optimization ✓ Full-text search and indexing ✓ Chat integration ready STATS: - 10 Go files (~120KB) - ~2,500+ lines of implementation code - ~350 lines of test examples - Full CLI command set - Zero external dependencies (stdlib only) Fixes: #122

PROBLEM:
DeepSeek incorrectly claimed SIN-Code was missing RAG, GOAP planning,
federation, and observability. These already existed in the canonical
cmd/sin-code/internal/ packages. Based on that false report, stub
implementations were added at the wrong package path (internal/ instead
of cmd/sin-code/internal/), were never imported anywhere, and were
strictly worse than the originals they duplicated.
REMOVED (18 files, ~2,100 lines of dead code):
internal/rag/ - duplicated cmd/sin-code/internal/memory/
internal/planning/ - duplicated cmd/sin-code/internal/orchestrator/
internal/federation/ - stub code, irrelevant for single-binary CLI
internal/observability/ - duplicated cmd/sin-code/internal/trace/
(which uses real OpenTelemetry SDK, not fake maps)
FIXED (1 line):
cmd/sin-code/rtk_cmd.go: broken import 'sin-code/internal/rtk'
corrected to 'github.com/OpenSIN-Code/SIN-Code/internal/rtk'
This was breaking the entire sin-code binary build.
UNCHANGED:
internal/spec - correctly wired, no duplicate, legitimate (#122)
internal/rtk - substantial real code (3,811 lines, real exec.Command,
cache, MCP integration, tests); kept pending decision
on whether the external 'rtk' binary will be provided

…rnal MCP tool) Compares CodeGraph (colbymchenry/codegraph) capabilities vs SIN-Code's existing graph engine (cartographer, impact, index). SIN-Code already has core symbol/call-graph, impact analysis, AST extraction, MCP serving. CodeGraph adds multi-language strength (20+ langs), SQLite/FTS5 indexing, cross-language bridging (Swift↔ObjC, React-Native), and native file-watcher. Proposes Option A: integrate CodeGraph as external MCP tool (similar to RTK pattern). - Zero duplication risk, leverages existing MCP architecture - ~200 LOC: install command + MCP proxy tool - Automatic multi-language context for agents - CodeGraph runs as separate service (or binary wrapper) Includes decision matrix + implementation sketch.

Summary
This branch delivers two real features and cleans up a batch of dead, duplicated code that was added based on an incorrect analysis.
Delivered
internal/spec): spec compiler, gates, validation, merge, metaspec, speckit +sin-code speccommand. Correctly wired intomain.go.internal/rtk): wraps the official RTK CLI proxy (https://github.com/rtk-ai/rtk) which compresses dev-command output to cut LLM token usage ~60-90%.
