Agent task: bootstrap embedding lab maturity spine and service manifest

[mdheller]

Agent-directed work package.

Target agent: Codex environment for SociOS-Linux/embeddinglab; Copilot coding agent if available.

Context:
embeddinglab is the Linux-native lab workspace for embeddings, rerankers, retrieval preparation, vector evaluation, and semantic indexing experiments for SocioProphet services. It should emit functional service manifests and evidence for governance; it must not self-promote models into production.

Scope:

1. Inspect the live repository before editing.
2. Add README explaining purpose and boundaries.
3. Add repo.maturity.yaml using repo-maturity.v1 semantics.
4. Add lab.manifest.json covering embeddings, rerankers, hybrid retrieval preparation, vector evaluation, and semantic indexing.
5. Add service-manifest/functional-service.v1.json conforming to SocioProphet/functional-model-surfaces semantics.
6. Add datasets/README.md, evals/README.md, adapters/README.md, training-runs/README.md, and examples/.
7. Add Makefile validation.

Acceptance criteria:

• make validate passes.
• Repo states lab-only boundary and governance handoff.
• Manifest can feed Holmes, Sherlock Search, model-router, and model-governance-ledger.
• No large model weights, datasets, secrets, or credentials are committed.

Boundary:
One PR only. Do not touch unrelated repos.

@codex Please take this embeddinglab issue. Implement the scoped lab maturity spine and service manifest in the issue body, then open one PR with validation evidence.

@copilot Please take this embeddinglab issue if available. Implement the scoped lab maturity spine and service manifest, then open one PR with validation evidence.

Summary

• Expanded README.md to define the lab-only purpose, explicit non-production boundaries, governance handoff, and key validation artifacts (repo.maturity.yaml, lab.manifest.json, and functional service manifest). README.mdL3-L43
• Added a scoped maturity spine in repo.maturity.yaml using repo-maturity.v1, including in-scope/out-of-scope definitions, governance handoff controls, and evidence requirements tied to make validate. repo.maturity.yamlL1-L34
• Added lab.manifest.json covering all requested capability areas (embeddings, rerankers, hybrid retrieval preparation, vector evaluation, semantic indexing), plus required downstream consumers and lab boundary flags. lab.manifest.jsonL1-L41
• Added service-manifest/functional-service.v1.json with functional-service.v1 schema semantics, explicit model surfaces, consumer integrations, and governance guardrails (promotion_allowed: false). service-manifest/functional-service.v1.jsonL1-L41
• Added scoped area docs for datasets/evals/adapters/training-runs/examples to establish repository structure and data/weight handling expectations. datasets/README.mdL1-L8 evals/README.mdL1-L3 adapters/README.mdL1-L3 training-runs/README.mdL1-L5 examples/README.mdL1-L3
• Added deterministic validation via Makefile + scripts/validate.py, including required-file checks, manifest capability/consumer checks, schema check, and governance constraint validation evidence output. MakefileL1-L4 scripts/validate.pyL1-L55

Testing
