From 1892a67fd8f570cb1fc81251d316d70e3a5dde29 Mon Sep 17 00:00:00 2001 From: pelikhan Date: Sun, 8 Nov 2026 16:02:38 -0800 Subject: [PATCH 1/9] Add AWF invocation skip decision gate Evaluate advisory skip questions before eligible built-in and declarative engine invocations inside AWF. Preserve deterministic retry safeguards and abstain on evaluation failures. Record sanitized outcomes in unified sessions and audit artifacts.

serialization utilities for safe expression handling and complete-document decoding. ## Overview The `jsonutil` package provides a thin wrapper around Go's standard `encoding/json` encoder to produce compact JSON output without HTML escaping. This is essential for serializing GitHub Actions expressions (e.g. `${{ env.X && env.Y }}`) that contain characters such as `&`, `<`, and `>` which the standard `json.Marshal` would otherwise encode as `\u0026`, `\u003c`, and `\u003e`. +It also decodes JSON strings without copying the input into a byte slice.
