Codex task: normalize NLPLab for Holmes language fabric and Prophet service manifests

[mdheller]

Mission

Normalize nlplab as the SociOS lab for classical NLP, linguistic primitives, entity/relation extraction, topic modeling, semantic parsing, and Holmes language pipeline evaluation.

This issue is designed for a Codex agent because it must align with Holmes, Sherlock Search, and Prophet Core Query. Keep the change bounded and open a PR.

Scope

Add a minimal lab skeleton without pulling heavy NLP/model dependencies:

• docs/LAB_SURFACE.md
• docs/PROPHET_INTEGRATION.md
• examples/functional-service.json
• examples/eval-fixture.json
• tools/validate_examples.py
• Makefile
• optional .github/workflows/validate.yml

Required Make targets

make validate
make emit-service-manifest
make emit-eval-fixture
make release-dry-run

Required semantics

• NLPLab is a lab surface for language pipeline experiments, not Holmes runtime service.
• Holmes owns the product language intelligence surface.
• Sherlock Search owns discovery/retrieval.
• Prophet Core Query owns shared governed query contracts.
• Platform service promotion belongs to SocioProphet/prophet-platform and governance ledgers.

Acceptance criteria

• make validate passes with no network or model downloads.
• make emit-service-manifest writes or prints the functional service manifest.
• make emit-eval-fixture writes or prints the eval fixture.
• Docs explain integration with holmes, sherlock-search, prophet-core-query, functional-model-surfaces, and prophet-platform.

Do not

• Do not download spaCy/Stanza/HF models.
• Do not vendor corpora or datasets.
• Do not implement real training jobs.
• Do not move Holmes product responsibilities into this lab.
