From 6dc33d83b7db8bdfff61a180cc7d0a5935b8b4b7 Mon Sep 17 00:00:00 2001 From: JUN <243035832+lidge-jun@users.noreply.github.com> Date: Tue, 27 Oct 2026 22:05:35 +0900 Subject: [PATCH] fix(responses): frame retained requests before portable checkpoints Recognize readable ocx1/ocx2 checkpoints before prompt lowering so retained requests receive the same historical framing as plaintext checkpoints. Keep canonical replay and the existing authorization note unchanged. Add offline default compaction JSON/SSE round trips and replay contracts for external handovers, later user intent, and native passthrough isolation. --- .../content/docs/reference/proxy-formats.md | 4 + scripts/test-layout/layout-replay.json | 1 + src/responses/compaction-history-framing.ts | 19 +- structure/transports/responses.md | 4 +- tests/fixtures/test-layout-expected.json | 1 + .../compaction-continuation-note.test.ts | 5 +- .../compaction-history-framing.test.ts | 3 +- .../compaction-portable-history.test.ts | 162 ++++++++++++++++++ 8 files changed, 189 insertions(+), 10 deletions(-) create mode 100644 tests/responses/compaction-portable-history.test.ts diff --git a/docs-site/src/content/docs/reference/proxy-formats.md b/docs-site/src/content/docs/reference/proxy-formats.md index 61eb7839155..786a56383fb 100644 --- a/docs-site/src/content/docs/reference/proxy-formats.md +++ b/docs-site/src/content/docs/reference/proxy-formats.md @@ -794,6 +794,10 @@ gets its own bearer.
