"""AgentLongBench x Flash Next, banco v2 (BRIEF-BENCH-ALB-V2): UNA domanda con UNA politica di contesto.
venv/bin/python scripts/run_alb_v2.py --file alb/data/benchmark/kf-c/64k/tool_response/find_duplicates_tool.jsonl \\
--qid 38_i13_j22_a_0031 --policy B --engine-url http://127.0.0.1:18797 --window 16384 --out runs/x
Politiche (stesso modello, campionamento, budget di risposta M e di ragionamento):
A finestra piena: i messaggi ufficiali (build_prompt) interi al motore.
T troncamento: via gli scambi più vecchi (anche tutti) finché prompt + M + MARGIN <= W; nota fissa al loro posto.
B compattazione: storia riletta scambio per scambio; quando lo scambio non entra, Flash Next riassume (system di
sola sintesi, senza ragionamento, budget = summary_max sempre garantito) e il contesto diventa system + riassunto.
D mnemonic-proxy installato (0.3.4), config proxy-cfg-D.json; la storia è rigiocata attraverso il proxy con una
richiesta max_tokens=1 (senza reasoning_budget_tokens) prima di ogni messaggio assistant; poi la domanda.
E D senza lo strumento recall offerto (inject_recall false).
Garanzie v2:
- A/T/B: ogni richiesta al motore è contata in modo esatto (template + tokenizer del pack) PRIMA dell'invio e parte
solo se prompt + max_tokens + MARGIN <= W; altrimenti nessun invio, status WindowRefused (mai uno sforamento).
- Tutte le chiamate al motore (anche quelle interne del proxy) passano dal contatore meter.py: costi completi in
engine_calls.jsonl e result["engine"], con il controllo a posteriori del margine anche per D/E.
- Esito della risposta finale classificato: vuota, chiamate residue, troncata (length), formato non valido.
