What Was Done

Sprint 284 — poly-compiler (steps 1948–1952) ✓

5-phase compiler pipeline: C++(lex) → Haskell(parse) → Rust(typecheck) → Lisp(optimize) → Go(emit)

Header	Description
CompilerPhaseSpec.h	CompilerPhaseSpec struct + CompilerPhaseRegistry (sorted by order field)
CompilerIRNode.h	IRNodeKind enum {Source,Token,AST,TypedAST,OptimizedAST,Bytecode} + IRNodePipeline queue
CompilerPhaseRouter.h	IRNodeKind → phaseId routing with optional fallback
CompilerPipelineRunner.h	Chains PhaseTransform functions in spec.order order; runAll / runUpTo
Sprint284IntegrationSummary.h	stepsCompleted=5, sprintName="Sprint 284: poly-compiler"

Tests: step1948_test.cpp – step1952_test.cpp — 26/26 pass Metrics: 1 call captured (4810 tokens — pipeline calls from prior session missed due to context compaction)

---

Sprint 285 — poly-everything (steps 1953–1957) ✓

Unified polyglot orchestration over 8 languages (C++, Python, Rust, Go, Haskell, TypeScript, Java, Lisp)

Header	Description
PolyglotFunctionMap.h	(language, functionName) → tag registry; lookup/hasFunction/languagesForFunction
PolyglotExecutionContext.h	LanguageConfig{timeout_ms, env, working_dir} per language; get/set/has
PolyglotResultAggregator.h	FunctionResult collection; AggregateReport{passCount,failCount,totalDurationMs,failedLanguages}
PolyglotOrchestrator.h	Ties map + context + aggregator; addFunction/setContext/recordResult/runSummary
Sprint285IntegrationSummary.h	stepsCompleted=5, sprintName="Sprint 285: poly-everything"

Tests: step1953_test.cpp – step1957_test.cpp — 26/26 pass Metrics: 8 calls, 6469 tokens

---

Phase 5 Complete

283	1943–1947	poly-pipeline	COMPLETE
284	1948–1952	poly-compiler	COMPLETE
285	1953–1957	poly-everything	COMPLETE

To Continue

1. Read docs/polyglot_orchestrator_sprint_plan.md for Phase 6 direction
2. Start at step 1958 with the standard workflow: start_recording → architect_intake → generate_taskitems → queue_ready → run_pipeline ×4 → implement → test → get_metrics → commit
