Segmented Real 1GB Retrieval — GLYPH v0.2

Branch:

• feature/segmented-v0.2

Setup:

• HDFS 1GB corpus
• split into 2 independent 512MB shards
• independent SA/BWT/FM built per shard

Manifest:

• manifests/segmented_1gb_real.json

Query:

• blk_-100000266894974466

Result:

• shard0 count: 18
• shard1 count: 0
• merged total_count: 18

Latency:

• query_time_sec: ~0.000319

Interpretation:

This is the first real segmented retrieval validation.

Each shard has an independent corpus and independent FM index.

The segmented query layer:

• dispatches queries across shards
• merges deterministic counts
• preserves exact retrieval semantics
