From f079020128170a0b44fa9d2aad38af2da69bb266 Mon Sep 17 00:00:00 2001 From: Vance Ingalls Date: Tue, 16 Jun 2026 21:33:27 -0700 Subject: [PATCH] =?UTF-8?q?feat(studio):=20stage=207=20step=203c=20?= =?UTF-8?q?=E2=80=94=20sdk=20cutover=20for=20inline-style=20ops?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces sdkCutoverPersist(): when STUDIO_SDK_CUTOVER_ENABLED is set, inline-style PatchOps are routed through the SDK session's in-memory document model instead of the server patch-element API. The SDK serialize() result is written back through the same writeProjectFile + editHistory.recordEdit path, so the on-disk output is identical to the legacy route. - packages/studio/src/utils/sdkCutover.ts (new): sdkCutoverPersist() + shouldUseSdkCutover() guard; domEditSaveTimestampRef.current is stamped on each write to suppress the echo file-change reload. - packages/studio/src/components/editor/manualEditingAvailability.ts: adds STUDIO_SDK_CUTOVER_ENABLED flag (default false); changes STUDIO_SDK_SHADOW_ENABLED default to false now that cutover is available. - packages/studio/src/hooks/useSdkSession.ts: adds optional domEditSaveTimestampRef param; self-write suppress window (SELF_WRITE_SUPPRESS_MS) gates file-change reloads so SDK writes don't echo back as external edits. - packages/studio/src/App.tsx: passes domEditSaveTimestampRef to useSdkSession so the suppress window can gate reloads triggered by SDK cutover writes. - Test coverage: sdkCutover.test.ts (new, 141 lines) + useDomEditSession.test.ts (new, 50 lines) — guard function + happy-path assertions.
