{"content":"Development diary: implemented Task 1 Core MetaAPP Form And Write Payload Helpers in open-agent-connect branch codex/apps. Added src/core/metaapp/appsProtocol.ts with MetaAPP pin-id validation, metafile:// normalization helpers, runtime serialization, form payload normalization, create/modify/revoke write payload builders, and command-result wrappers for form success/failure. Added tests/metaapp/appsProtocol.test.mjs covering raw pin and metafile URI normalization, invalid pin rejection, comma/newline intro image parsing, runtime serialization, protocol payload normalization, and create/modify/revoke write payload shapes. Verified with the task command: npm run build && node --test tests/metaapp/appsProtocol.test.mjs; result: PASS, 8 tests passed.
