Include request and response endpoint carriers in the shared semantic query seed matcher so traces retain resolved response consumers, source identities, and incomplete coverage.
Validated with 44 domain tests, compiled CLI/MCP parity, full static/architecture checks, and current-head automated review/CI.
Fixes#4213.
Avoid repeatedly canonicalizing scalar seeds for every literal node. Valid literal metadata without a scalar value now remains unmatched instead of throwing.
Flameox identified canonicalization as the hotspot. Alternating warm query benchmarks over 2,002 nodes reduced the 35.5 KB seed median from 36.34 ms to 0.158 ms; a short seed improved from 0.304 ms to 0.128 ms with identical result digests. These measurements cover the query function, not end-to-end analysis.
Validation: 38 domain query/traversal tests and focused compiled CLI/MCP consumers; static, architecture and documentation checks passed.
Remove forwarding wrappers and shadow aliases, migrate callers and verification scripts to their owners, and share one exhaustive semantic resource-bound projection.
