Thoth (tht) è il prodotto, PSD è il cliente. Nessun riferimento al contesto
clinico nel codice.
Rinomine:
- comando+package nsp→tht (dir nsp/→tht/, 46 import, pyproject entry point)
- gate nsp-gate.js→tht-gate.js (+ rewrite token, relayIfNspFails→relayIfThtFails)
- workspace chirone.{example,test}.yaml→tht.{example,test}.yaml (generici)
- env THOTH_→THT_ (19 var) + NSP_ stragglers (NSP_HARNESS_ROOT, NSP_SESSION)
- commenti/docstring chirone/psdwp3/policlinico neutralizzati ('the reference
implementation', 'the DWH')
Aggiunto [tool.setuptools.packages.find] include=['tht*'] (necessario: l'auto-
discovery rompeva con tht/ + workspaces/ come top-level multipli).
.env operatore aggiornato in-place (prefissi THT_, valori preservati, gitignored).
Verifica: pytest 109 passed, npm test 14 pass, tht phase meta --json OK, zero
residui nsp/THOTH_/NSP_/chirone nel package.

"""SQL concept->formula evidence store (spec D14b, §4.7).
|
|
|
|
A concept (e.g. 'fascia pediatrica', 'ablazione') maps to a reusable SQL formula
|
|
(a CASE WHEN ...) that derives it from physical columns. These are reviewable
|
|
units: the gate surfaces a candidate formula, the reviewer approves or rejects it
|
|
(decision types concept_formula_approved / concept_formula_rejected), and approved
|
|
formulas travel with the schema-linking artifact.
|
|
|
|
Storage: one file per formula, frontmatter YAML + SQL body (same shape as
|
|
EvidenceDoc.parse). Directory layout: <root>/formulas/<slug>-<n>.sql.md.
|
|
Retrieve is by concept (may return several, e.g. competing drafts vs reviewed).
