PR Review: PASS (NOT VERIFIED)

What This Does

Updates documentation/generated docs to align UnifiedEvent id wording for SDK consumers reading docs.

Blast Radius

Docs and generated API doc config only; no runtime core or SDK client code changed.

Consumer Verification

Before (base branch):
Base docs contained the older/misaligned UnifiedEvent id description. No runtime consumer API behavior differs.

After (PR branch):
PR branch updates docs. Core build passed; core Jest tests passed (24 suites, 644 tests). Root verification then stopped at Python SDK tests because pytest is not installed.

Test Results

• Build: PASS
• Unit tests: CORE PASS (24 suites, 644 tests; root verification blocked by missing pytest)
• Server starts: PASS during root verification
• E2E smoke: N/A (docs-only)

Findings

No blocking findings.

PMXT Pipeline Check

Semver Impact

patch -- documentation correction.

Risk

Generated docs freshness depends on the docs generation pipeline; runtime behavior was not affected.
