Le 3 radici intra-CLI, portate con rename psdwp3->tht + fix path import (session.phase -> phase). Espongono gli helper condivisi: CONFIG_OPT (config_cmd), _load_config_or_exit/ physical_path/annotations_path (schema_cmd), session_dir/load_session_or_exit (session_cmd). Drift phase fix in session_cmd (7 siti): MAX_PHASE -> wf.max_phase, PHASE_NAMES -> wf.phase_name(), SCHEMA_LINKING_PHASE -> wf.schema_linking_phase(). Le vecchie costanti non esistono piu' in tht.phase (sono metodi su Workflow dalla Onda -1/F2). Check grep-per-file applicato: trovati e fixati 4 residui (config/nsp.yaml, 2x 'nsp schema introspect', 'Sessioni PsdWp3') che il sed psdwp3->tht non tocca. Lesson del fix precedente applicata. session_cmd importa sql_cmd lazy (dentro finalize_cmd) -> non si rompe finche' sql_cmd (Onda 4) non sara' portato. Suite: 161 passed. tht --help ora mostra phase, config, schema, session.
ThothII harness — tht
The self-contained Pi layer of ThothII: a deterministic Python CLI (tht) + a Pi gate
extension (.pi/extensions/tht-gate.js) that runs the 8-phase NL→SQL workflow,
emitting and consuming widget-descriptor JSON. Derived from the reference implementation as a validated
starting point, adapted (not assumed reliable) to the ThothII contract.
Install
cd harness
python -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
The tht command is now on PATH. Node ≥ 20 is needed for the gate JS tests
(npm test).
Configure
.env (gitignored — secrets live ONLY here)
cp .env.example .env
# fill in: THT_PROFILE, THT_DB_*, THT_DWH_API_KEY, THT_VEC_API_KEY,
# THT_VEC_WRITE_API_KEY, THT_SSL_CA, THT_OLLAMA_URL, ...
Keys are never logged; URLs are fine. Rotate any key that appeared in chat.
workspaces/<name>.yaml
A workspace wires the relational DWH + the pgvector (dual-key) + embeddings + evidence.
See workspaces/tht.example.yaml. ${THT_*}} tokens expand from .env.
The workflow
workflow.yaml is the single source of workflow truth (spec F2). Eight phases
(F1 chiarimento → F8 datamart). Edit it to change the workflow; phase.py, the gate,
and the skill all read from it — no mirrored constants to drift.
tht phase meta --json # the gate reads workflow facts from here
tht phase meta # human-readable
Run
The harness runs inside Pi (pi --mode rpc, cwd = harness/):
pi --mode rpc
# in Pi: /nuova-domanda "<your question in natural language>"
The gate (tht-gate.js) presents reviewer widgets (widget-descriptor), the reviewer
decides, and tht persists decisions to the append-only ledger (review_decisions.jsonl).
See docs/testing.md for what each interaction level validates.
Test
pytest # L0 (testcontainers, real Postgres) + L1 (pure logic + gate builders)
npm test # gate widget-builder golden + fuzzy tests (JS)
pytest -m l2 # L2: real GLM 5.2 + remote DWH (pre-release; needs .env + VPN + CA bundle)
L0 needs Docker (present on the dev machine). L2 is manual, non-deterministic, and
skips cleanly without .env. See docs/testing.md for the honest split of what each
level covers and — crucially — does not cover.
