This PR mathematically locks down the GitGalaxy COBOL modernization pipeline with 76 invariants.

Key components validated:

  • ETL Unpacker (EBCDIC to UTF-8/CSV translation & COMP-3 hex decoding)
  • Graveyard Reaper & Microservice Slicer (IR context shielding, recursive taint tracking)
  • Cloud Schema Forge (Legacy PIC to PostgreSQL DDL & JSON Schema routing)
  • AI Agent Task Forge (Anomaly to JSON ticket generation)
  • Compiler Forge (Dialect-aware compiler routing and cyclic recursion failsafes)

…der routing

Expands the test suite to secure the AST-free COBOL JCL templating engine:

- Intent Extractor: Proves column-7 comment stripping, UT-S- DD isolation, and transactional (CICS/SQL) block counting.

- Zero-Trust Templating: Mathematically verifies job card generation and safe data disposition (DISP=NEW/SHR) routing.

- Hygienic Defaults: Asserts that the E2E CLI securely partitions forged JCLs into isolated, timestamped output directories.
Expands the test suite to validate the static COBOL memory and logic analyzer:

- Copybook Shapeshifter: Proves the resolver accurately injects local .cpy files and executes strict word-boundary REPLACING substitutions.

- AST Math: Mathematically verifies the set-difference logic for calculating orphaned variables and unreachable phantom paragraphs.

- E2E Summary: Asserts the CLI correctly recurses file structures to aggregate the estimated LOC bloat removed.
…y deflection

Expands the test suite to validate the GitGalaxy Data Lineage Orchestrator:

- Ghost Deflector: Proves the IR-context engine successfully blanks out dead paragraphs to prevent hallucinated data dependencies.

- Topological Sort: Mathematically verifies Kahn's Algorithm accurately maps Producers -> Consumers to determine flawless execution order.

- Cycle Trap: Asserts the engine correctly halts and identifies circular data deadlocks before generating an impossible pipeline.
Expands the test suite to mathematically lock down the GitGalaxy Data Bridge:

- Schema Calculator: Proves the engine accurately parses PIC clauses to calculate physical byte boundaries and COMP-3 compression logic.

- Hexadecimal Decoder: Mathematically verifies that IBM packed decimal bytes are correctly parsed into Python floats with perfect sign and decimal precision.

- E2E Binary Pipeline: Asserts the script flawlessly slices an EBCDIC byte stream, converts cp037 to UTF-8, and outputs clean CSV data.
…bypass

Expands the test suite to validate the GitGalaxy pre-processor AST sanitization:

- Dialect Sensor: Proves the regex accurately dates compilers based on COBOL-85 scope terminators (END-IF, EVALUATE).

- COBOL-85 Modernization: Mathematically verifies the dangerous NEXT SENTENCE trap is safely rewritten to CONTINUE.

- COBOL-74 Strict Mode: Asserts that legacy code strictly normalizes spacing without injecting crash-inducing modern syntax.

- Fast-Exit Guard: Proves the I/O system cleanly bypasses safe files without triggering disk writes.
…ation

Expands the test suite to mathematically lock down the GitGalaxy Cloud Schema Forge:

- Translation Engine: Proves the regex accurately converts COBOL PIC boundaries to PostgreSQL types (VARCHAR, SMALLINT, DECIMAL).

- Bloat Cutter: Mathematically verifies the IR context drops dead variables, FILLER padding, and 88-level conditions from the cloud schema.

- Honesty Sensor: Asserts the engine correctly intercepts dynamic legacy footprints (COMP-3, DEPENDING ON) and injects architectural warnings into the DDL.
… agents, and compiler routing

Relocated test files to the correct directory and finalized the validation of the COBOL modernization pipeline:

- Cloud Schema Forge: Validated PIC to SQL translation.

- Agent Task Forge: Validated JSON ticket generation.

- Compiler Forge: Validated dialect routing.
…lsafe

Finalizes the GitGalaxy testing suite by locking down the Pre-Compiler Forge:

- Dialect Router: Proves the generation engine dynamically switches between legacy (COBUCL) and modern (IGYWCL) compilers based on AST syntax analysis.

- Cyclic Failsafe: Mathematically verifies the MAX_RECURSION_DEPTH limit successfully breaks infinite copybook loops without crashing the pipeline stack.

- Pipeline Integrity: Asserts the E2E script successfully inlines dependencies, provisions physical IEFBR14 disk space, and exports an executable JCL payload.
Adds integration tests for the master GitGalaxy orchestrator:

- Scale Sensor: Proves dynamic toggling between RAM and SQLite based on repo mass.

- State Parity: Mathematically verifies identical read/write behaviors across hybrid mediums.

- Payload Integrator: Asserts seamless handoffs between the Graveyard, Schema, and Lineage tooling.
