From d75ed505d7dd1e73d58defae19b1c2dc1f3e1da6 Mon Sep 17 00:00:00 2001 From: felixxia-oai Date: Mon, 7 Sep 2026 21:09:17 +0000 Subject: [PATCH] Move Guardian REPL evidence rendering into the shared context registry (#43602) ## What changed Move completed REPL response rendering into `codex-guardian-context` and register a synchronous-only `NodeReplEvidence` section. Core supplies a borrowed view of its evidence snapshot and retains responsibility for capture, storage eviction, and the delivery cursor. Preserve the existing text and multimodal layouts, rendering bounds, omission markers, image ordering, and deduplication. Exclude evidence payloads from the rendered section's debug output. ## Testing Adapt the existing evidence tests to exercise the shared renderer. Extend registry coverage to verify synchronous-only inclusion, rendered content, and omission of evidence payloads from debug output.
