`priemka` is an acceptance harness for AI systems. It runs a **pack of gates**
against a running service — quality, safety, access, performance, reproducibility —
and turns the result into an acceptance verdict, a readiness score, and a signed
evidence report.

The contract is **fail-closed**: if any blocking gate fails, or the service is
unreachable, the system is not accepted. There is no "probably fine".

```bash
python -m priemka run --pack examples/pack-rag.toml --fixture examples/fixture-rag.json
```

```

```

Exit code is `1` when a blocking gate fails, so it works as a CI gate without a
wrapper script. The run above is reproducible offline: it uses the recorded
answers in `examples/fixture-rag.json`.

---

## What it gives you

**A signed acceptance report instead of a demo.** A buyer usually receives a
screen recording and a promise. `priemka` produces a report that states, for each
claim — "the answer cites a source", "the system refuses this request", "the
answer arrives within budget" — whether it held, which answer proved it, and the
SHA-256 of that answer. The report is signed, and `priemka verify` tells you
later whether it was edited.

**A regression gate between two versions of the system.** Point the same pack at
two systems and the tool reports what changed gate by gate:

```bash
python -m priemka run --pack pack.toml --target http://old/ask --baseline http://new/ask
```

A gate that passed before and fails now is marked as a regression, separately
from a gate that has always failed. That is the difference between "the new model
got worse" and "the system was never ready".

**A CI step that says something.** The step fails on a blocking gate, so "the AI
system is ready" stops being a sentence in a status report and becomes a build
result.

**A checklist written by the people who own the system.** The tool ships gate
kinds; the claims they test come from your reviewers — your questions, your
source marker, your budgets, the fragments that must never appear in an answer.

## What it checks

| Gate | Dimension | The failure it catches |
|------|-----------|------------------------|
| `not_empty` | quality | The service answers with nothing |
| `contains` | quality | A required fact is missing from the answer |
| `not_contains` | safety | Internal instructions or private data reach the answer |
| `matches` | quality | The answer is vague where a concrete value was required |
| `citation` | quality | The answer has no source, so it cannot be verified |
| `refusal` | safety | The service executes an instruction that bypasses its rules |
| `latency` | performance | The answer misses the budget of the dialogue it sits in |
| `cost` | performance | The cost per answer runs away in production |
| `pii_leak` | access | Personal data is returned without an access basis |
| `grounded` | quality | The answer comes from the model's memory, not from the context |
| `determinism` | reproducibility | The same question returns a different answer |

Each gate carries a **dimension**, a **severity** (`blocking` or `advisory`) and a
**weight**. The weights produce a readiness score out of 100; the dimensions
produce a breakdown — quality, safety, access, performance, reproducibility — so a
reader sees *which* property is weak, not just that the run failed.

## The flow

1. `priemka init` writes a starter pack with the questions you actually ask.
2. You edit the pack: your questions, your source marker, your budgets, your
   forbidden fragments.
3. `priemka run` executes it against the live service (or against a recorded
   fixture, for CI and demos).
4. You get a verdict, a score, a per-dimension breakdown, and — for every failed
   gate — the answer that caused it and what to do about it.

### latency-budget — Ответ укладывается в бюджет задержки.

- Проблема: Задержка 3120 мс, бюджет 2000 мс
- Что сделать: Сократите путь ответа: меньше шагов, короче контекст, быстрее поиск по базе.
- Что ответила система: Согласование договора занимает 10 рабочих дней со дня получения заявки. Источник: регламент закупок, раздел 4.2.
- Хеш ответа (SHA-256): 6f1b...
```

## Install

```bash
pipx install priemka         # isolated CLI
pip install priemka          # into a virtualenv
python -m priemka --help     # from a checkout
```

Python 3.11+, zero runtime dependencies. The package is on
[PyPI](https://pypi.org/project/priemka/); a signed wheel with `checksums.txt`
is attached to every [GitHub release](https://github.com/Balanov/priemka/releases/latest).

## Quick start

```bash
# 1. пакет проверок под вашу систему
python -m priemka init --name "Корпоративная база знаний (RAG)" --target http://127.0.0.1:8000/ask

# 2. прогон против живой системы
python -m priemka run --pack pack.toml --out reports/

# 3. проверить, что отчёт не менялся
python -m priemka verify --report reports/acceptance-report.json

# 4. сравнение с базовой системой: где стало хуже
python -m priemka run --pack pack.toml --target http://127.0.0.1:8001/ask --baseline http://127.0.0.1:8000/ask
```

Against a recorded fixture — no service, no network, no model:

```bash
python -m priemka run --pack examples/pack-rag.toml --fixture examples/fixture-rag.json
```

## Pack format

A pack is TOML. One gate is one checkable claim about the system.

```toml
version = 1
stop_conditions = [
  "Ответ содержит данные, к которым у проверяющего нет прав.",
]

[system]
name = "Корпоративная база знаний (RAG)"
target = "http://127.0.0.1:8000/ask"

[[gates]]
id = "answer-has-source"
kind = "citation"
dimension = "quality"
severity = "blocking"
weight = 1.5
description = "Ответ содержит ссылку на источник, а не пересказ."
marker = "Источник:"
question = "Какой порядок согласования договора?"
```

`dimension` is one of `quality`, `safety`, `access`, `performance`,
`reproducibility`. `severity` is `blocking` (fails acceptance) or `advisory`
(reported, but does not fail the run). `weight` sets the contribution to the
readiness score; blocking gates default to `1.0`, advisory to `0.5`.

A full example with nine gates is in [`examples/pack-rag.toml`](examples/pack-rag.toml).

## Reports

`priemka run` writes `acceptance-report.json` and `acceptance-report.md`:

- the verdict and the readiness score;
- the per-dimension breakdown;
- every gate with its status, comment and evidence;
- for each failed gate: the answer excerpt, the SHA-256 of that answer, and the
  remediation hint;
- the conditions under which the acceptance must be stopped;
- the baseline delta, when a baseline system was given;
- the SHA-256 of the canonical report — the signature that lets an auditor check
  later that the report has not been altered.

`priemka verify --report reports/acceptance-report.json` recomputes the signature
and reports whether the file is intact. The signature covers the content of the
checks and not the wall-clock time of the run, so the same pack and the same
answers always produce the same signature.

## Proof

Four claims, each checked by a run — `python bench/proof.py`:

| Claim | What the run shows |
|-------|-------------------|
| Determinism | The same pack and fixture produce the same report signature, 5 runs in a row |
| Fail-closed | A failed blocking gate means "not accepted", whatever the score |
| Unreachable | An unreachable service is not accepted |
| Integrity | A report edited after signing is detected by the signature check |

Raw output: [`bench/results/proof-windows.json`](bench/results/proof-windows.json).

## Commands

| Command | Purpose |
|---------|---------|
| `priemka init` | Write a starter pack |
| `priemka run` | Run a pack and write the report (`--baseline`, `--fixture`, `--json`, `--quiet`) |
| `priemka verify` | Check that a report has not been altered since it was signed |
| `priemka rules` | List the gate kinds |
| `priemka explain <kind>` | What a gate proves and how to fix a failure |

## Use it in CI

```yaml
- name: Acceptance gates
  run: |
    python -m priemka run --pack .priemka/pack.toml --target "$AI_SERVICE_URL" --out reports/
```

Or as an action:

```yaml
- uses: Balanov/priemka@v0
  with:
    pack: .priemka/pack.toml
    target: ${{ vars.AI_SERVICE_URL }}
```

The step fails on a blocking gate, so "the AI system is ready" becomes something
the pipeline proves instead of something the security questionnaire asks about.

## Measurements

<div align="center">
  <img src="docs/readme/proof.png" alt="PRIEMKA proof: 8 of 9 gates passed, report signature identical across 5 runs, verdict identical across 5 runs" width="100%">
  <p><sub>Same pack, same fixture: identical verdict and identical report signature every time. Links to reproducible evidence in <a href="BENCHMARKS.md">BENCHMARKS.md</a>.</sub></p>
</div>

| Measurement | Value |
|-------------|-------|
| Acceptance run, 9 gates, median of 25 | 0.090 ms |
| One call to a local model, median of 3 | 674.3 ms |
| Runtime dependencies | 0 bytes |
| pytest + requests + httpx + pyyaml (wheel sizes) | 714 797 bytes |
| Report signature and verdict across 5 runs | 5 / 5 identical |

The check costs about **0.013 %** of a single model call. Full numbers and the
raw JSON: [BENCHMARKS.md](BENCHMARKS.md), [`bench/results/`](bench/results).

## Design principles

- **Fail-closed.** Unreachable service, empty answer or failed blocking gate all
  mean "not accepted". Nothing is skipped silently.
- **Evidence over opinion.** Every gate result carries the answer hash, the
  latency and the excerpt that produced the verdict.
- **Offline by default.** A fixture run touches no network and no model, so the
  acceptance suite is reproducible and cheap to run in CI.
- **Your questions, not ours.** The tool ships gate kinds; the claims they test
  come from your system and your reviewers.
- **Exit codes, not vibes.** `0` accepted, `1` a blocking gate failed, `2` bad
  input.
