📄 Description

Problem

Ollama structured JSON generation fails with HTTP 500 errors:

curl -X POST http://localhost:11434/api/generate \
  -d '{"model": "mistral", "format": {"url": "string"}}'
# Response: {"error":"invalid JSON schema in format"}

Impact: 500 errors prevent JSON generation, high retry rate

Root Cause

Passing schema dict to format parameter (Ollama expects "json" string)

Solution

Add format parameter support and use format="json":

# Use format="json" for GBNF grammar constraint
response = self.generate(structured_prompt, system_prompt, format="json")

How it works: Ollama enforces valid JSON at token level via GBNF grammar

Impact

✅ Eliminates 500 errors
✅ Ollama enforces JSON validity
✅ 31/31 tests pass
✅ Cleanup pipeline preserved as fallback

Testing

31/31 unit tests pass
All 4 call sites verified
Exploit rescue mechanism preserved
Line-by-line impact analysis completed

Note

Introduce robust radare2 integration with auto-install and SARIF export, security and disassembly improvements, a Semgrep scan fix, new RADARE2 config, and extensive tests/docs.

Binary analysis (radare2):

Add new radare2_wrapper.py with JSON-based disassembly, decompilation, xrefs, call graphs, strings, imports/exports, and analysis helpers.

Implement address sanitization (command injection prevention), normalization, and backward disassembly dedup/sort.

Provide utilities like format_disassembly_text() and availability check.

CrashAnalyser integration:

Integrate radare2 (prefers r2, falls back to objdump); add background auto-install with CI detection, status (get_install_status), readiness (is_radare2_ready), reload (reload_radare2), and cancellation (cancel_install).

Add SARIF export APIs (crashes_to_sarif_dict, export_crashes_to_sarif).

Static analysis:

Fix Semgrep directory scanning by adding --no-git-ignore in scanner.py.

Config:

Add RADARE2_* settings; default analysis depth aa; size-based timeout.

Docs:

Extensive new/updated docs (architecture, integration, reviews, validation, status, plans, audits).

Tests:

Large test suite additions for radare2 features, security, address handling, backward disassembly, integration workflow, installation logic, performance, and renaming validation.
