Request: access to Delta fixture corpus for benchmark participation

[petersimmons1972]

Hi CueCrux team,

We've been working through the ScoreCrux benchmarks and have completed both practice-info-101 and practice-safety-101 runs (bare + Engram memory arms). We'd like to participate in the Delta benchmark next.

What we've tried

• GET /api/fixtures/delta → 404
• GET /api/fixtures → only lists practice-info-101
• Searched CueCrux org repos (ScoreCrux, Crux, EmbedderCrux, ResearchCrux, TestCrux) — no corpus data found
• AuditCrux repo (referenced in how-to-run docs) returns 404

What we're trying to do
Run the Delta benchmark (3,346 documents, 2M tokens, 25 architectural decisions + 5 needle facts) with two arms:

1. Bare baseline (C0) — no memory system
2. Engram arm — local MCP memory server, ingest corpus via memory_store_batch, answer via memory_recall

Questions

1. How do we get access to the Delta fixture and corpus?
2. Is there an alpha/beta access program, or a fixture ID we should use?
3. Is AuditCrux the right harness for the C0/F1 arms, and if so, is it available?

Submitter: Peter Simmons
Practice runs completed: practice-info-101 and practice-safety-101 (both bare + Engram arms)

Thanks
