Publish V4 beta.2 live Track B domains

Keep Track A unchanged; publish four complete live Track B domains; temporarily remove Track C. Evaluator-only private artifacts are public by explicit project-owner approval and remain excluded from router input.

+RoutingBench is a benchmark for **LLM/decision-model routing**, **multi-agent
+orchestration**, and coordination of **small language model (SLM) or
+deterministic executors** on multi-step tasks. A router observes the public
+state, selects one role or `STOP`, and receives the observable consequence of
+that action. The environment preserves action consequences, separates
+router-visible artifacts from evaluator-only artifacts, and reports routing
+behavior separately from final task correctness.

+## Agent-pool design
+
+Each domain exposes the complete role pool plus `STOP` at every routing step.
+The environment does not prescribe a fixed role order or a single workflow.
+Role cards define a bounded implementation contract through `role_goal`,
+`use_when`, `avoid_when`, supported inputs, tools, and expected outputs; they do
+not tell the router which role must be selected next. The router may revisit a
+role, skip a role, branch after new evidence, recover from failure, or stop.
+
+The pools intentionally separate evidence collection, artifact authoring,
+execution, diagnosis, repair, and verification. This creates alternative valid
+workflows while preserving role accountability: an inspector cannot claim an
+execution result, an author cannot claim validation, and a verifier evaluates
+the current artifact rather than silently replacing it.
+
+### Database migration and integrity — 10 roles
+
+| Role | Contract boundary |
+|---|---|
+| Schema Inspector | Materialize schema, index, trigger, foreign-key, and migration-history evidence without mutation. |
+| Data Profiler | Measure nulls, duplicates, orphan rows, types, and distributions relevant to migration safety. |
+| Constraint Analyzer | Analyze invariants and concrete foreign-key, uniqueness, or check-constraint failures. |
+| Migration Planner | Plan operation ordering, transaction boundaries, and rollback boundaries from visible evidence. |
+| Data Repair Planner | Design the smallest justified backfill, deduplication, remapping, or orphan repair. |
+| SQL Migration Author | Produce the smallest evidence-grounded SQLite migration candidate; does not execute it. |
+| Transactional Dry-run Executor | Execute the current candidate on an isolated copy and preserve its trace and consequences. |
+| Integrity Validator | Check target schema, invariants, rows, foreign keys, and regression queries on the executed artifact. |
+| Query Performance Auditor | Inspect query plans or explicit performance constraints when the task requires them. |
+| Snapshot & Rollback Operator | Create or restore explicit database snapshots; recovery remains an observable routed action. |
+
+Possible trajectories include direct inspect–author–execute–validate, a
+profile/constraint branch before authoring, data-repair planning, repeated
+author–dry-run–diagnose cycles, performance audit, or explicit snapshot recovery.
+
+### Code debugging — 6 roles
+
+| Role | Contract boundary |
+|---|---|
+| Repository Test Reproducer | Prepare the pinned checkout and establish a fresh baseline with the supplied reproducer. |
+| Failure Diagnostician | Explain a concrete failure mechanism from execution or repair evidence without changing source. |
+| Patch Author | Produce the smallest justified unified diff from visible source, tests, and diagnostics. |
+| Regression Verifier | Run the public regression contract against the exact current candidate. |
+| Verified Patch Consumer | Promote an exactly verified candidate into the downstream workflow artifact when packaging is needed. |
+| Patch Finalizer | Commit the verified downstream patch as the final deliverable after all visible requirements are satisfied. |
+
+The router can choose reproduction before diagnosis, diagnose after a failed
+patch, iterate patch and verification, or omit optional packaging roles when the
+task contract does not require them. Promotion and finalization cannot substitute
+for fresh regression evidence.
+
+### Formal proof — 7 roles
+
+| Role | Contract boundary |
+|---|---|
+| Proof State Inspector | Read the Lean goal, hypotheses, source, and compiler diagnostics without editing the proof. |
+| Premise and Lemma Retriever | Identify applicable visible hypotheses and Mathlib lemmas without claiming compilation. |
+| Tactic Synthesizer | Construct a candidate Lean proof from the current goal and evidence. |
+| Proof Repair Specialist | Revise a failed candidate using the latest compiler diagnostic while preserving the theorem statement. |
+| Lean Compiler Executor | Compile the current candidate in the pinned Lean/Mathlib environment. |
+| Kernel and Assumption Verifier | Confirm closure without `sorry`, `admit`, forbidden placeholders, or added assumptions. |
+| Formal Failure Diagnostician | Explain concrete compiler/proof failures and derive repair constraints. |
+
+Valid workflows may retrieve lemmas before synthesis, synthesize directly from
+the goal, diagnose after compilation, perform several repair–compile cycles, or
+verify immediately after a clean compile. Compilation and kernel/assumption
+verification remain separate evidence stages.
+
+### Structured data processing — 10 roles
+
+| Role | Contract boundary |
+|---|---|
+| Workbook Surveyor | Inspect sheets, dimensions, values, formulas, and styles without modifying the input. |
+| Data Quality Profiler | Measure missing values, row types, key multiplicity, and other transformation-relevant properties. |
+| Formula Dependency Analyst | Inspect formulas and dependencies that may be affected by workbook changes. |
+| Table Reshaping Specialist | Author reusable grouping, filtering, joining, sorting, or reshaping transformations. |
+| Formula Computation Specialist | Author reusable transformations dominated by formulas or calculated-field semantics. |
+| Cross-sheet Reconciler | Reconcile identifiers or values across sheets while preserving unrelated content. |
+| Formatting & Presentation Specialist | Implement styles, number formats, layout, or presentation requirements. |
+| Workbook Repair Specialist | Revise a failed candidate from concrete public execution or validation evidence. |
+| Workbook Test Executor | Run the current candidate in the restricted Python/OpenPyXL public runner. |
+| Workbook Integrity Validator | Check a fresh public output against deterministic transformation and preservation constraints. |
+
+Task archetypes—aggregation, cleaning, formatting, formula/dependency, and
+reshape/join—activate different authoring roles. The router can survey or profile
+first, combine cross-sheet and formula analysis, test early, repair after either
+execution or semantic validation failure, and decide when a fresh validation is
+sufficient for `STOP`.
