GLYPH PRODUCT BASELINE v1

Status: LOCKED INDEX CORE

Core locked:

• SA32u format
• BWT format
• FM format
• v5 retrieval semantics
• no chunk_map
• chunk_id = SA[i] >> 14

Validated:

• 4GB physical shard
• 8GB logical segmented prototype
• exact retrieval
• deterministic results

Reference implementation:

• glyph_live_retrieve_v5.py
• glyph_segmented_live_v3.py
• parallel shard fan-out
• warm query latency ~1.3-1.7 ms

Not locked:

• HTTP layer
• daemon layer
• router implementation
• API format
• systemd service
• multi-process scaling

Production safety requirements:

• bind only to 127.0.0.1
• one uvicorn worker initially
• request lock around router stdin/stdout
• timeout required
• health endpoint required
• graceful shutdown required
• systemd MemoryMax required

Do not change without new baseline:

• SA format
• BWT format
• FM format
• v5 retrieval semantics
