S08.03 slice 7: wire Origin SD into FreeRTOS example (untag origin.feature)

[DavidCozens]

Parent epic: #268 (S08.03 — UDP syslog from FreeRTOS reaches the oracle)

Background

Slice 5 left the FreeRTOS example wiring no structured data (SolidSyslogConfig.sd = NULL); slice 6 (#307) closed the cmdline-flag gap so prival / message_fields / udp_mtu Full delivery now run on the FreeRTOS BDD runner. Slice 7 wires the first SD — Origin — bringing 4 of origin.feature's 5 scenarios into the green column.

Scope

Wire SolidSyslogOriginSd_Create into Example/FreeRtos/SingleTask/main.c::InteractiveTask using the same fixture pattern as the Linux/Windows examples:

• software = "SolidSyslogExample" — hardcode in main.c, matching Example/SingleTask/SolidSyslogExample.c
• swVersion = "0.7.0" — same; the BDD assertion is byte-exact
• enterpriseId = EXAMPLE_ENTERPRISE_ID — from Example/Common/ExampleEnterpriseId.h
• IP getters: reuse Example/Common/ExampleIps.c by adding it (and its include path) to the FreeRTOS source list in Example/FreeRtos/SingleTask/CMakeLists.txt. Same fake "192.0.2.1" as Linux/Windows.

Wire originSd into a sdList[1] and update SolidSyslogConfig.sd / .sdCount. Add destroy calls in reverse order in InteractiveTask.

Tag movement: drop the feature-level @freertoswip from origin.feature; keep scenario-level @freertoswip on scenario 5 only (All standard structured data present — also asserts sequenceId and tzKnown, which need meta SD + timeQuality SD wired in subsequent slices).

Out of scope

• Real-IP enumeration via FreeRTOS_GetEndPoints / getifaddrs / GetAdaptersAddresses. Tracked as a follow-up to revisit at S08.03 (S08.03: UDP syslog from FreeRTOS reaches the oracle #268) closure.
• Lifting software / swVersion to a shared Example/Common constant. Linux/Windows currently hardcode in their own main.c too; consistency wins for now.
• Wiring meta SD or timeQuality SD. Subsequent slices.

Acceptance

• behave --tags='not @wip and not @freertoswip and @udp' Bdd/features/origin.feature against syslog-ng-freertos: 4 of 5 scenarios pass, 1 skipped (All standard structured data present).
• Full FreeRTOS BDD sweep: 5 features green, 14 scenarios passing (slice 6 baseline 4 / 10 plus slice 7's +1 / +4).
• cmake --build --preset freertos-cross --target SolidSyslogFreeRtosSingleTask clean.
• clang-format --dry-run --Werror on touched C files clean.
• DEVLOG appended.
