Execution mapping (implemented work)

Completed in tooling/code:

• Step 1859: Added strictness audit utility

  • tools/mcp/audit_grammar_strictness.py

• Step 1860: Added canonical schema normalizer

  • tools/mcp/schema_normalizer.py

• Step 1861: Refactored grammar generator to normalized-schema recursive flow

  • tools/mcp/generate_tool_grammars.py

• Step 1862: Added strictness policy gate

  • tools/mcp/grammars/strictness_policy.json
  • tools/mcp/check_strictness_policy.py

• Step 1863: Added sprint 163 integration summary artifact

  • editor/src/Sprint163IntegrationSummary.h

• Step 1864: Implemented recursive object/array grammar rule generation

  • tools/mcp/generate_tool_grammars.py

• Step 1865: Added union handling in strict generation flow

  • tools/mcp/generate_tool_grammars.py

• Step 1866: Added constraint-aware scalar/object handling (where representable)

  • tools/mcp/generate_tool_grammars.py

• Step 1867: Added strict grammar CI runner and reproducible checks

  • tools/mcp/run_grammar_ci_checks.sh

• Step 1868: Added sprint 164 integration summary artifact

  • editor/src/Sprint164IntegrationSummary.h

• Step 1869: Enforced strictness policy checking

  • tools/mcp/check_strictness_policy.py
  • tools/mcp/grammars/strictness_policy.json

• Step 1870: Added artifact fingerprinting and lock verification

  • tools/mcp/grammars/manifest.json
  • tools/mcp/grammars/manifest.lock
  • tools/mcp/verify_grammar_manifest.py

• Step 1871: Added CI integration script for strict grammar pipeline

  • tools/mcp/run_grammar_ci_checks.sh

• Step 1872: Added runtime strict grammar verification path

  • tools/mcp/validate_slm_runtime.sh (STRICT_GRAMMARS=1)

• Step 1873: Added sprint 165 integration summary artifact

  • editor/src/Sprint165IntegrationSummary.h

Verification

Executed:

• ./tools/mcp/run_grammar_ci_checks.sh

Result: PASS

Coverage status:

• Tool schemas: 347
• Per-tool GBNF files: 347
• Dispatch schema oneOf entries: 347

Current strictness report:

• unwaived_fallback_count: 390
• unsupported_schema_entry_count: 1

Policy is configured to fail on any regression beyond this baseline.
