Phase 3, Task 10: SensorML Index

Status: COMPLETED — commit d2a2139

Deliverables

File	Lines	Description
index.ts	143	Barrel file: 8 runtime exports (parseSensorML30, SensorMLParseError, 5 shared helpers, SENSORML_PROCESS_TYPES) + 42 type-only exports covering all public interfaces
index.spec.ts	94	12 tests: runtime export verification, constructability, integration

Test Results

• 6 suites, 233 tests pass (all SensorML tests)
• Zero regressions

Design Decisions

• Explicit named export { X } from / export type { Y } from — no export * for tree-shaking clarity
• Sub-parser internals (parseSimpleProcess, etc.) intentionally NOT re-exported — they are implementation details consumed by parser.ts
• Type exports grouped by category (primitives, metadata, capabilities, I/O, settings, frames, positions, events, process hierarchy, components)"

📋 Required Reading: Phase 3 Lessons Learned

Before starting work on this issue, review the Phase 3 Lessons Learned document:

👉 docs/governance/phase-3-lessons-learned.md

Instructions:

1. Read the lessons learned document first — before reading the issue body
2. Read phase-2-lessons-learned.md second — Lessons 8 (multi-server) and 10 (read-only smoke tests) remain mandatory
3. Review AI_OPERATIONAL_CONSTRAINTS.md as always

Key lessons applicable to all Phase 3 work:

• Lesson 1: Upstream audit check — before building new layers
• Lesson 2: Postel's Law — never gate extraction on validation
• Lesson 10: Type naming rules when defining types from external specs
