Ports the leaf data-layer modules and validates them: - mschema/ (models, eligibility, merge, render), db/ (connection, sampling, introspect, fetch_ca), rest/client.py -- renamed psdwp3->nsp, verbatim. - L0 (testcontainers, real Postgres): db connection read-only enforcement (psd_ro cannot CREATE/INSERT), introspect against a known schema (tables, columns, types, comments, FKs, enum, composite PK), sampling most-frequent values + truncation reporting. 15 tests, ~4s. - L1 (fake data): rest/client RPC contract (mocked transport -- X-API-Key header, payloads, base_url slash handling, HTTP/network error surfacing), mschema/render 3 formats (markdown, mschema-text, schema-dict) + eligibility rules (wide_text excluded, short_text/numeric/enum/temporal/ boolean eligible, annotation override wins). 25 tests. pyproject registers l0/l2 markers + addopts '-m not l2' (L2 opt-in). Deferred to their dependency-porting tasks: test_rrf.py (search needs vectorstore, B3) and the 11 CLI contract tests (need _guards/session, wired when each command lands). 'Not assumed reliable' now has real teeth for the data layer; CLI/search contracts follow.
