Problem: Anthropic API didn't support thinking blocks or signatures for reasoning models.
Solution: Added thinking content blocks support to Anthropic Messages API. Fixed missing signature fields and duplicate content_block_start events in streaming. Tested with DeepSeek-R1 and Qwen3-Thinking.

Problem: Tool call chunks without index failed to merge properly in streaming, causing 422 errors.
Solution: Fixed bug where tool_call_chunks without valid index failed to merge properly in streaming with stream_mode="messages". Modified merge_lists() function to merge chunks by shared id or sequentially. Added unit tests.

Problem: Chat templates crashed when applying |length filter on Undefined type in minja engine.
Solution: Full flow trace through minja engine: missing keys return Undefined (not None), so `is not none` evaluates True and `|length` fails on Undefined. Audited all templates in models/templates/, identified 4 vulnerable (Apriel, DeepSeek-R1-Distill-Qwen-32B, DeepSeek-R1-Distill-Llama-8B, llama-cpp-deepseek-r1) and 8 fragile. Proposed template fix (`is defined` guard) and engine fix (register length on value_undefined_t).

Problem: Inverse hyperbolic functions (sinh^-1, cosh^-1) errored with values > 10^100 due to incorrect validation.
Solution: Bug analysis where IsCurrentTooBigForTrig() applied the 10^100 limit indiscriminately to all trigonometric and hyperbolic functions. Inverse hyperbolics are logarithms in disguise (sinh^-1(x) = ln(x + sqrt(x^2 + 1))), with no periodicity issues. Proposed fix: check m_bInv flag before rejecting large values to exempt inverse hyperbolics.

Problem: CVE-2026-26335: RCE in Calero VeraSMART due to hardcoded ASP.NET machine keys.
Solution: Template request to detect CVE-2026-26335 (CVSS 9.8) in Calero VeraSMART (pre-2022 R1). Shared ASP.NET cryptographic keys across installations allow forging malicious ViewState and achieving unauthenticated remote code execution via deserialization.

Problem: Missing sourcemaps caused build tool errors like SWC.
Solution: Identified that .npmignore excluded .map files despite tsconfig.json generating them. OpenAI includes 844 and Anthropic 296 sourcemaps in their SDKs. Proposed solution to include the 652 .map files.

Problem: xinclude-injection template generated false positives due to overly permissive regex.
Solution: The regex `root:.*?:[0-9]*:[0-9]*:` matched minified JavaScript content like `PEAM_root:config:123:456:`. Fixed to `root:[^:]*:\d+:\d+:` to restrict to non-colon characters and require at least one digit in UID/GID.

Problem: DocumentBlock incorrectly coerced empty strings to None in optional fields.
Solution: Fixed bug where DocumentBlock class converted empty strings to None using Python truthiness evaluation. Changed `or` logic to explicit `is None` checks in document_mimetype and title fields. Added unit tests.

Problem: Vulkan Docker couldn't detect GPUs due to missing libglvnd libraries.
Solution: Mesa Vulkan ICD couldn't initialize properly and vkEnumeratePhysicalDevices() returned empty list. Added libglvnd0, libgl1, libglx0, libegl1 and libgles2 libraries to Dockerfile.

Problem: CVE-2025-34291: CORS vulnerability in Langflow AI allowing token theft.
Solution: Template to detect CVE-2025-34291 in Langflow AI (≤1.6.9). Misconfigured CORS reflects any origin with credentials allowed, chained with RCE via /api/v1/validate/code.
