Summary

The thin-edge.io client (tedge-zephyr/) moves to its own repository, thin-edge/tiny-edge, with its history (thin-edge/tiny-edge#1). This repository becomes the example of applications built with it. tiny-edge is laid out as a portable core plus one port per RTOS, so it can later support FreeRTOS, ThreadX, QNX, and VxWorks.

Its board profiles (lib/common/tedge-boards/), the Smart Functions, the client's own DTM sets (zephyr_tedge, zephyr_tedge_remote_access), its OpenSpec specs and archived changes, and the tedge-zephyr CI workflow move with it.

Changes

• west.yml adds tiny-edge as a west project at modules/lib/tiny-edge. West adds it as a Zephyr module, so the four apps no longer list it in ZEPHYR_EXTRA_MODULES.
• release/devices.yml refers to the profiles as "{tiny-edge}/ports/zephyr/profiles/...". matrix.py resolves those paths with west list. Where west is missing (the release workflow's matrix job), it skips the existence check. package.py reads tiny-edge's VERSION the same way.
• scripts/measure_tedge.sh, the READMEs, SCOPE.md, DEVICES.md, and the OpenSpec config point at tiny-edge.
• cumulocity/ keeps the applications' DTM sets and points at tiny-edge for the Smart Functions.

Unchanged: Kconfig, the tedge_* API, every message a device sends, and the release JSON keys (tedgeZephyrVersion included).

For developers: run west update once to fetch tiny-edge. To work on the client and an app together, mount a tiny-edge clone over /ws/modules/lib/tiny-edge (README, "First-time workspace setup").

Testing

Four release images were built from main and from this branch against tiny-edge 48a42201 (now released as v0.1.0): tedge-agent-tedge-full-esp32c6-devkitc, modbus-server-tedge-ota-esp32-devkitc, snmp-agent-tedge-ota-esp32-cam, and opcua-server-tedge-ota-qtpy-esp32s3.

• The sorted .config is identical for all four.
• C6: every loadable section is identical.
• Xtensa: no symbol changed size in the Modbus image. Two Zephyr networking functions in the OPC-UA image changed by 4 bytes each. .text changed by 16 B and 144 B, smaller in both. This comes from the new link order (west modules now link before the app's extra modules), not from the client.
• The client's unit tests (native_sim) and the 29 Kconfig checks pass from tiny-edge.
• The release-script unit tests pass (43), including a new test for {project}/ paths. matrix.py validates release/devices.yml with west.

Not flashed to hardware: the client's code compiles the same, and the only differences are link-order placement.

Release

west.yml pins tiny-edge v0.1.0, the first release from its own repository (thin-edge/tiny-edge#1, thin-edge/tiny-edge#2). Its code is the same as 48a42201, which the testing above used. The only differences are VERSION (0.0.2 → 0.1.0) and the new changelog.
