New evidence/formula_store.py: ConceptFormula (concept, columns, sql, status,
sources) as a frontmatter-YAML + SQL-body unit, stored one-file-per-formula under
<formulas>/<slug>-<n>.sql.md. save_formula is append-only (competing drafts and
reviewed versions coexist); retrieve_formula(concept) returns all of them so the
gate can surface candidates and let the reviewer choose.
concept_formula_approved / concept_formula_rejected added to DecisionType
(records the reviewer's choice; approved formulas travel with schema-linking).
L1: test_formula (7 tests) -- retrieval by concept, save/reload roundtrip (SQL
body preserved, frontmatter well-formed), multiple formulas per concept, empty
on no-match / missing dir, decision-type existence, default draft status.
Deferred: --kind formula on nsp search (needs search_cmd porting) wires
retrieve_formula into the CLI; lands with the search command.
Ports vectorstore/{rest_client,rest_writer,store,reader,embeddings,records},
evidence/model (leaf dep of records), and cli/_guards (require_vector_write_allowed
workstation write-guard). Renamed psdwp3->nsp, verbatim.
VectorRestClient gains an api_key property so reader/writer clients carry their
distinct keys visibly (spec D11: vector_reader / vector_writer on the same endpoint).
scripts/create_vector_reader_rpc.sql is NEW: the reader RPCs (search_similar,
list_tables) lived server-side in Supabase and were never versioned. Authored now
mirroring the writer allowlist pattern (table allowlist, security definer, revoke
from anon/authenticated, grant to vector_reader only). Writer RPC ported verbatim.
L1: test_vector_dual_key (7 tests) pins the dual-key construction + the workstation
write-guard (exit 4 without writer key).
