+### Phase 1012: Tag Pipeline — raw files to per-tag MAT via registry, batch and live
+
+**Goal:** Deliver a MATLAB pipeline that ingests arbitrary delimited raw files (.csv/.txt/.dat) and emits per-tag .mat files keyed off TagRegistry, in two modes: BatchTagPipeline (synchronous one-shot) and LiveTagPipeline (timer-driven incremental append via modTime+lastIndex, mirroring MatFileDataSource). Outputs round-trip through the existing SensorTag.load() contract unchanged; MonitorTag/CompositeTag remain lazy per MONITOR-03. Binding lives on a new RawSource struct property on SensorTag + StateTag (Tag base untouched per Pitfall 1). Per-tag try/catch isolation + end-of-run TagPipeline:ingestFailed throw. Shared delimited-text parser (textscan-based, Octave 7+ compatible — no readtable/readmatrix).
+**Requirements**: No exclusive REQ-IDs (v2.0 closed at Phase 1011 MIGRATE-03); scope captured by CONTEXT.md decisions D-01..D-19 (see 1012-CONTEXT.md).
+**Depends on:** Phase 1011
