From 52ea2c27e276d6e4844a22021f7f95af54b6f67f Mon Sep 17 00:00:00 2001 From: Madeuss Date: Tue, 1 Sep 2026 21:55:02 -0300 Subject: [PATCH] feat(api): let one suspect answer a question MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit E2's first half. A turn runs end to end, guarded at every step, and none of it needs an API key: dossier, prompt, schema, scope, canary, stance machine and turn accounting all work against the fake model. Only the words are synthetic. The order is the design: dossier -> prompt -> model -> schema -> scope -> canary -> stance -> statement Everything before the model is projection; everything after it is verification. The model produces one thing, a line of dialogue, and every consequence of that line is decided by code around it (RN-022, RN-023, RN-042). Building it found a hole the rules had anticipated and the code had not. The culprit was alone with the victim, so no presence fact was ever written about them at that hour, and nothing in their own dossier incriminates them — a culprit would have answered with the same easy conscience as an innocent without an alibi, and the mystery would have had no centre. RN-011 already allowed for this: the Solution entity stays out, but "o culpado sabe apenas da própria culpa". So the dossier became the boundary. It is the one place that reads the solution, and what crosses is a single bit about oneself — never the means, the motive, the chain, or who else might have done it. The stance machine takes the model's suggestion and overrules it when the move is illegal, silently for the player and reported for the evals. `broken` is unreachable from a suggestion: a suspect breaks when confronted with evidence, which is a computed game event and not a mood a model may adopt because the question felt intense. A rejected reply still costs the turn. A budget that only charged for answers the system liked would be a budget to farm by provoking failures. Also fixes the fake to omit optional fields rather than invent them. It was filling fact_referenced with a synthetic id, which the scope guard correctly rejected — an invented id is precisely what that guard exists to catch. --- Makefile | 5 +- README.md | 10 +- apps/api/src/firenze/cli.py | 50 +++- apps/api/src/firenze/domain/__init__.py | 6 + apps/api/src/firenze/domain/models.py | 59 ++++ .../api/src/firenze/interrogation/__init__.py | 16 ++ apps/api/src/firenze/interrogation/dossier.py | 60 ++++ apps/api/src/firenze/interrogation/guard.py | 72 +++++ apps/api/src/firenze/interrogation/models.py | 31 ++ apps/api/src/firenze/interrogation/stance.py | 37 +++ apps/api/src/firenze/interrogation/turn.py | 144 ++++++++++ apps/api/src/firenze/model/fake.py | 16 +- apps/api/src/firenze/prompts.py | 16 ++ apps/api/src/firenze/veneer/writer.py | 11 +- apps/api/tests/test_interrogation.py | 269 ++++++++++++++++++ apps/api/tests/test_model_port.py | 2 + docs/08-achados.md | 22 ++ prompts/npc/v1.md | 69 +++++ 18 files changed, 876 insertions(+), 19 deletions(-) create mode 100644 apps/api/src/firenze/interrogation/__init__.py create mode 100644 apps/api/src/firenze/interrogation/dossier.py create mode 100644 apps/api/src/firenze/interrogation/guard.py create mode 100644 apps/api/src/firenze/interrogation/models.py create mode 100644 apps/api/src/firenze/interrogation/stance.py create mode 100644 apps/api/src/firenze/interrogation/turn.py create mode 100644 apps/api/src/firenze/prompts.py create mode 100644 apps/api/tests/test_interrogation.py create mode 100644 prompts/npc/v1.md diff --git a/Makefile b/Makefile index 6ea27b4..d04d3fa 100644 --- a/Makefile +++ b/Makefile @@ -2,7 +2,7 @@ COMPOSE := docker compose -f infra/compose/docker-compose.yml API := apps/api .DEFAULT_GOAL := help -.PHONY: help dev down logs psql install api case openapi lint fmt typecheck test check migrate evals +.PHONY: help dev down logs psql install api case ask openapi lint fmt typecheck test check migrate evals help: ## lista os alvos @grep -hE '^[a-z-]+:.*?## ' $(MAKEFILE_LIST) | sed 's/:.*## /\t/' | expand -t 14 @@ -29,6 +29,9 @@ api: ## roda a API local com reload (sem container) case: ## gera um caso (make case SEED=42 [LOCALE=en] [REVEAL=1] [VENEER=1]) cd $(API) && uv run firenze generate --seed $(or $(SEED),1) --locale $(or $(LOCALE),pt-BR) $(if $(REVEAL),--reveal,) $(if $(VENEER),--veneer,) +ask: ## pergunta a um suspeito (make ask SEED=42 WHO=sus-1 Q="onde voce estava?") + cd $(API) && uv run firenze ask --seed $(or $(SEED),1) --suspect $(or $(WHO),sus-1) --question "$(Q)" --locale $(or $(LOCALE),pt-BR) + openapi: ## regenera apps/api/openapi.json cd $(API) && uv run python scripts/dump_openapi.py diff --git a/README.md b/README.md index 9256d09..bda00f2 100644 --- a/README.md +++ b/README.md @@ -9,8 +9,9 @@ character has no way of knowing. ![CI](https://github.com/Madeuss/firenze/actions/workflows/ci.yml/badge.svg) -> **Status: phase 1 of 8.** The case generator and its solver work.
