-                      Version 3, 29 June 2007
-
-Copyright (C) 2007 Free Software Foundation, Inc. &lt;https://fsf.org/&gt;
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-
-                           Preamble
-
- The GNU General Public License is a free, copyleft license for</code></pre>
-
-<p>software and other kinds of works.</p>
-
-<pre class="code ruby"><code class="ruby">The licenses for most software and other practical works are designed</code></pre>
-
-<p>to take away your freedom to share and change the works.  By contrast, the
-GNU General Public License is intended to guarantee your freedom to share
-and change all versions of a program–to make sure it remains free software
-for all its users.  We, the Free Software Foundation, use the GNU General
-Public License for most of our software; it applies also to any other work
-released this way by its authors.  You can apply it to your programs, too.</p>
-
-<pre class="code ruby"><code class="ruby">When we speak of free software, we are referring to freedom, not</code></pre>
-
-<p>price.  Our General Public Licenses are designed to make sure that you have
-the freedom to distribute copies of free software (and charge for them if
-you wish), that you receive source code or can get it if you want it, that
-you can change the software or use pieces of it in new free programs, and
-that you know you can do these things.</p>
-
-<pre class="code ruby"><code class="ruby">To protect your rights, we need to prevent others from denying you</code></pre>
-
-<p>these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.</p>
-
-<pre class="code ruby"><code class="ruby">For example, if you distribute copies of such a program, whether</code></pre>
-
-<p>gratis or for a fee, you must pass on to the recipients the same freedoms
-that you received.  You must make sure that they, too, receive or can get
-the source code.  And you must show them these terms so they know their
-rights.</p>
-
-<pre class="code ruby"><code class="ruby">Developers that use the GNU GPL protect your rights with two steps:</code></pre>
-
-<p>(1) assert copyright on the software, and (2) offer you this License giving
-you legal permission to copy, distribute and/or modify it.</p>
-
-<pre class="code ruby"><code class="ruby">For the developers&#39; and authors&#39; protection, the GPL clearly explains</code></pre>
-
-<p>that there is no warranty for this free software.  For both users&#39; and
-authors&#39; sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.</p>
-
-<pre class="code ruby"><code class="ruby"><span class='const'>Some</span> <span class='id identifier rubyid_devices'>devices</span> <span class='id identifier rubyid_are'>are</span> <span class='id identifier rubyid_designed'>designed</span> <span class='id identifier rubyid_to'>to</span> <span class='id identifier rubyid_deny'>deny</span> <span class='id identifier rubyid_users'>users</span> <span class='id identifier rubyid_access'>access</span> <span class='id identifier rubyid_to'>to</span> <span class='id identifier rubyid_install'>install</span> <span class='kw'>or</span> <span class='id identifier rubyid_run'>run</span>
-</code></pre>
-
-<p>modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of protecting
-users&#39; freedom to change the software.  The systematic pattern of such
-abuse occurs in the area of products for individuals to use, which is
-precisely where it is most unacceptable.  Therefore, we have designed this
-version of the GPL to prohibit the practice for those products.  If such
-problems arise substantially in other domains, we stand ready to extend
-this provision to those domains in future versions of the GPL, as needed to
-protect the freedom of users.</p>
-
-<pre class="code ruby"><code class="ruby">Finally, every program is threatened constantly by software patents.</code></pre>
-
-<p>States should not allow patents to restrict development and use of software
-on general-purpose computers, but in those that do, we wish to avoid the
-special danger that patents applied to a free program could make it
-effectively proprietary.  To prevent this, the GPL assures that patents
-cannot be used to render the program non-free.</p>
-

-
-<pre class="code ruby"><code class="ruby">&quot;The Program&quot; refers to any copyrightable work licensed under this</code></pre>

-<p>License.  Each licensee is addressed as “you”.  “Licensees” and

-
-<pre class="code ruby"><code class="ruby">To &quot;modify&quot; a work means to copy from or adapt all or part of the work</code></pre>
-
-<p>in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a “modified version” of the
-earlier work or a work “based on” the earlier work.</p>
-
-<pre class="code ruby"><code class="ruby">A &quot;covered work&quot; means either the unmodified Program or a work based</code></pre>

-
-<p>permission, would make you directly or secondarily liable for infringement
-under applicable copyright law, except executing it on a computer or
-modifying a private copy.  Propagation includes copying, distribution (with
-or without modification), making available to the public, and in some
-countries other activities as well.</p>
-
-<pre class="code ruby"><code class="ruby">To &quot;convey&quot; a work means any kind of propagation that enables other</code></pre>
-

-
-<p>to the extent that it includes a convenient and prominently visible feature
-that (1) displays an appropriate copyright notice, and (2) tells the user
-that there is no warranty for the work (except to the extent that
-warranties are provided), that licensees may convey the work under this
-License, and how to view a copy of this License.  If the interface presents
-a list of user commands or options, such as a menu, a prominent item in the
-list meets this criterion.</p>
-
-<pre class="code ruby"><code class="ruby">1. Source Code.
-
-The &quot;source code&quot; for a work means the preferred form of the work</code></pre>
-
-<p>for making modifications to it.  “Object code” means any non-source form of
-a work.</p>
-
-<pre class="code ruby"><code class="ruby">A &quot;Standard Interface&quot; means an interface that either is an official</code></pre>
-
-<p>standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that is
-widely used among developers working in that language.</p>
-
-<pre class="code ruby"><code class="ruby">The &quot;System Libraries&quot; of an executable work include anything, other</code></pre>

-packaging a Major Component, but which is not part of that Major Component,
-and (b) serves only to enable use of the work with that Major Component, or
-to implement a Standard Interface for which an implementation is available
-to the public in source code form.  A “Major Component”, in this context,
-means a major essential component (kernel, window system, and so on) of the
-specific operating system (if any) on which the executable work runs, or a
-compiler used to produce the work, or an object code interpreter used to
-run it.</p>
-
-<pre class="code ruby"><code class="ruby">The &quot;Corresponding Source&quot; for a work in object code form means all</code></pre>
-
-<p>the source code needed to generate, install, and (for an executable work)
-run the object code and to modify the work, including scripts to control
-those activities.  However, it does not include the work&#39;s System
-Libraries, or general-purpose tools or generally available free programs
-which are used unmodified in performing those activities but which are not
-part of the work.  For example, Corresponding Source includes interface
-definition files associated with source files for the work, and the source
-code for shared libraries and dynamically linked subprograms that the work
-is specifically designed to require, such as by intimate data communication
-or control flow between those subprograms and other parts of the work.</p>

-facilities for running those works, provided that you comply with the terms
-of this License in conveying all material for which you do not control
-copyright.  Those thus making or running the covered works for you must do

-
-You may convey a work based on the Program, or the modifications to</code></pre>
-
-<p>produce it from the Program, in the form of source code under the terms of
-section 4, provided that you also meet all of these conditions:</p>
-
-<pre class="code ruby"><code class="ruby">  a) The work must carry prominent notices stating that you modified
-  it, and giving a relevant date.
-
-  b) The work must carry prominent notices stating that it is
-  released under this License and any conditions added under section
-  7.  This requirement modifies the requirement in section 4 to
-  &quot;keep intact all notices&quot;.
-
-  c) You must license the entire work, as a whole, under this
-  License to anyone who comes into possession of a copy.  This
-  License will therefore apply, along with any applicable section 7
-  additional terms, to the whole of the work, and all its parts,
-  regardless of how they are packaged.  This License gives no
-  permission to license the work in any other way, but it does not
-  invalidate such permission if you have separately received it.
-
-  d) If the work has interactive user interfaces, each must display
-  Appropriate Legal Notices; however, if the Program has interactive
-  interfaces that do not display Appropriate Legal Notices, your
-  work need not make them do so.
-
-A compilation of a covered work with other separate and independent</code></pre>
-
-<p>works, which are not by their nature extensions of the covered work, and
-which are not combined with it such as to form a larger program, in or on a
-volume of a storage or distribution medium, is called an “aggregate” if the
-compilation and its resulting copyright are not used to limit the access or
-legal rights of the compilation&#39;s users beyond what the individual
-works permit.  Inclusion of a covered work in an aggregate does not cause
-this License to apply to the other parts of the aggregate.</p>
-
-<pre class="code ruby"><code class="ruby">6. Conveying Non-Source Forms.
-
-You may convey a covered work in object code form under the terms</code></pre>
-
-<p>of sections 4 and 5, provided that you also convey the machine-readable
-Corresponding Source under the terms of this License, in one of these ways:</p>
-
-<pre class="code ruby"><code class="ruby">  a) Convey the object code in, or embodied in, a physical product
-  (including a physical distribution medium), accompanied by the
-  Corresponding Source fixed on a durable physical medium
-  customarily used for software interchange.
-
-  b) Convey the object code in, or embodied in, a physical product
-  (including a physical distribution medium), accompanied by a
-  written offer, valid for at least three years and valid for as
-  long as you offer spare parts or customer support for that product
-  model, to give anyone who possesses the object code either (1) a
-  copy of the Corresponding Source for all the software in the
-  product that is covered by this License, on a durable physical
-  medium customarily used for software interchange, for a price no
-  more than your reasonable cost of physically performing this
-  conveying of source, or (2) access to copy the
-  Corresponding Source from a network server at no charge.
-
-  c) Convey individual copies of the object code with a copy of the
-  written offer to provide the Corresponding Source.  This
-  alternative is allowed only occasionally and noncommercially, and
-  only if you received the object code with such an offer, in accord
-  with subsection 6b.
-
-  d) Convey the object code by offering access from a designated
-  place (gratis or for a charge), and offer equivalent access to the
-  Corresponding Source in the same way through the same place at no
-  further charge.  You need not require recipients to copy the
-  Corresponding Source along with the object code.  If the place to
-  copy the object code is a network server, the Corresponding Source
-  may be on a different server (operated by you or a third party)
-  that supports equivalent copying facilities, provided you maintain
-  clear directions next to the object code saying where to find the
-  Corresponding Source.  Regardless of what server hosts the
-  Corresponding Source, you remain obligated to ensure that it is
-  available for as long as needed to satisfy these requirements.
-
-  e) Convey the object code using peer-to-peer transmission, provided
-  you inform other peers where the object code and Corresponding
-  Source of the work are being offered to the general public at no
-  charge under subsection 6d.
-
-A separable portion of the object code, whose source code is excluded</code></pre>

-a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular

-or common use of that class of product, regardless of the status of the
-particular user or of the way in which the particular user actually uses,
-or expects or is expected to use, the product.  A product is a consumer

-(regardless of how the transaction is characterized), the Corresponding
-Source conveyed under this section must be accompanied by the Installation

-
-<pre class="code ruby"><code class="ruby">The requirement to provide Installation Information does not include a</code></pre>

-

-  Notices displayed by works containing it; or

-  any liability that these contractual assumptions directly impose on
-  those licensors and authors.
-
-All other non-permissive additional terms are considered &quot;further</code></pre>

-<p>restrictions“ within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is

-you may remove that term.  If a license document contains a further
-restriction but permits relicensing or conveying under this License, you

-
-<pre class="code ruby"><code class="ruby">9. Acceptance Not Required for Having Copies.
-
-You are not required to accept this License in order to receive or</code></pre>
-
-<p>run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission to
-receive a copy likewise does not require acceptance.  However, nothing
-other than this License grants you permission to propagate or modify any
-covered work.  These actions infringe copyright if you do not accept this
-License.  Therefore, by modifying or propagating a covered work, you

-
-<pre class="code ruby"><code class="ruby">10. Automatic Licensing of Downstream Recipients.
-
-Each time you convey a covered work, the recipient automatically</code></pre>

-<pre class="code ruby"><code class="ruby">An &quot;entity transaction&quot; is a transaction transferring control of an</code></pre>

Добавлен новый калькулятор PositionAware, который гарантирует,
что обменник займёт позицию внутри целевого диапазона, а не перепрыгнет выше.

Реализованные use cases:
- UC-1..UC-4: Базовая логика без перепрыгивания позиций выше
- UC-6: Адаптивный GAP для плотных рейтингов
- UC-8: Исключение своего обменника из расчёта (Gera.our_exchanger_id)
- UC-9: Защита от манипуляторов с аномальными курсами

Архитектура:
- Паттерн Strategy: Legacy (старое поведение) и PositionAware (новое)
- Выбор калькулятора через поле calculator_type в ExchangeRate
- Обратная совместимость: по умолчанию используется Legacy

Конфигурация:
- Gera.our_exchanger_id - ID обменника для исключения из расчёта
- Gera.anomaly_threshold_percent - порог аномалий (по умолчанию 50%)

Closes #69

+```ruby
 Gera.configure do |config|
   config.cross_pairs = { kzt: :rub, eur: :rub }
+
+  # Автокурс: ID нашего обменника в BestChange (для исключения из расчёта позиции)

+### Autorate Calculator Types
+
+Для каждого направления обмена (`ExchangeRate`) можно выбрать тип калькулятора автокурса:
+
+```ruby
+# Legacy (по умолчанию) - старый алгоритм
+exchange_rate.update!(calculator_type: 'legacy')
+
+# PositionAware - новый алгоритм с защитой от перепрыгивания позиций
+exchange_rate.update!(calculator_type: 'position_aware')
+```
+
+**PositionAware** гарантирует, что обменник займёт позицию внутри целевого диапазона (`position_from..position_to`), а не перепрыгнет выше. Поддерживает:
+- Адаптивный GAP для плотных рейтингов
+- Исключение своего обменника из расчёта
+- Защиту от манипуляторов с аномальными курсами

+## Алгоритм расчета комиссии
+
+### Ключевой сервис: `Gera::RateComissionCalculator`
+
+**Файл:** `vendor/gera → gera/app/services/gera/rate_comission_calculator.rb`
+
+Итоговая комиссия складывается из трех компонентов:
+
+```ruby
+def commission
+  auto_comission_by_external_comissions + auto_comission_by_reserve + comission_by_base_rate
+end
+```
+
+---
+
+### Компонент 1: Комиссия по позиции в BestChange
+
+**Метод:** `auto_comission_by_external_comissions`
+
+**Логика:**
+1. Загружаются данные обменников из `BestChange::Repository`
+2. Фильтруются по диапазону позиций `position_from..position_to`
+3. Из них выбираются те, чья комиссия попадает в диапазон `autorate_from..autorate_to`
+4. Берется первый обменник, из его комиссии вычитается `AUTO_COMISSION_GAP` (0.01)
+
+```ruby
+# Строки 161-172
+def auto_comission_by_external_comissions
+  return 0 unless could_be_calculated?
+
+  external_rates_in_target_position = external_rates[(position_from - 1)..(position_to - 1)]
+  return autorate_from unless external_rates_in_target_position.present?
+
+  external_rates_in_target_comission = external_rates_in_target_position.select { |rate|
+    ((autorate_from)..(autorate_to)).include?(rate.target_rate_percent)
+  }
+  return autorate_from if external_rates_in_target_comission.empty?
+
+  target_comission = external_rates_in_target_comission.first.target_rate_percent - AUTO_COMISSION_GAP
+end
+```
+
+---
+
+### Компонент 2: Комиссия по резервам
+
+**Метод:** `auto_comission_by_reserve`
+
+**Логика:**
+1. Для income и outcome платежных систем ищутся `AutoRateSetting` с `direction: 'income'/'outcome'`
+2. Сравнивается текущий резерв (`reserve`) с базовым резервом (`base`)
+3. Определяется направление: `'plus'` если резерв >= базы, иначе `'minus'`
+4. Рассчитывается процент отклонения: `(max - min) / min * 100`
+5. Ищется checkpoint с `checkpoint_type: 'reserve'` и подходящим `value_percents`
+6. Усредняются `min_boundary` и `max_boundary` от обеих платежных систем
+
+```ruby
+# Строки 96-110
+def income_reserve_checkpoint
+  income_auto_rate_setting.checkpoint(
+    base_value: income_auto_rate_setting.reserve,
+    additional_value: income_auto_rate_setting.base,
+    type: 'reserve'
+  )
+end
+
+# AutoRateSetting#checkpoint (app/models/auto_rate_setting.rb:18-21)
+def checkpoint(base_value:, additional_value:, type:)
+  direction = base_value >= additional_value ? 'plus' : 'minus'
+  find_checkpoint(reserve_ratio: calculate_diff_in_percents(base_value, additional_value), direction: direction, type: type)
+end
+```
+
+---
+
+### Компонент 3: Комиссия по базовому курсу
+
+**Метод:** `comission_by_base_rate`
+
+**Логика:**
+1. Получается текущий курс валют (`current_base_rate`)
+2. Получается средний курс за последние 24 часа (`average_base_rate`)
+3. Сравниваются значения
+4. Ищется checkpoint с `checkpoint_type: 'by_base_rate'`
+5. Усредняются границы
+
+```ruby
+# Строки 54-63
+def current_base_rate
+  return 1.0 if same_currencies?
+  Gera::CurrencyRateHistoryInterval
+    .where(cur_from_id: in_currency.local_id, cur_to_id: out_currency.local_id)
+    .last.avg_rate
+end
+
+def average_base_rate
+  return 1.0 if same_currencies?
+  Gera::CurrencyRateHistoryInterval
+    .where('interval_from > ?', DateTime.now.utc - 24.hours)
+    .where(cur_from_id: in_currency.local_id, cur_to_id: out_currency.local_id)
+    .average(:avg_rate)
+end
+```
+
+---
+
+## Применение комиссии к курсу
+
+### 1. Получение итоговой комиссии
+
+**Файл:** `gera/app/models/gera/exchange_rate.rb:159-161`
+
+```ruby
+def final_rate_percents
+  @final_rate_percents ||= auto_rate? ? rate_comission_calculator.auto_comission : rate_comission_calculator.fixed_comission
+end
+```
+
+### 2. Расчет конечного курса
+
+**Файл:** `gera/app/models/gera/direction_rate.rb:139-145`
+
+```ruby
+def calculate_rate
+  self.base_rate_value = currency_rate.rate_value
+  raise UnknownExchangeRate unless exchange_rate
+
+  self.rate_percent = exchange_rate.final_rate_percents  # ← Берется auto или fixed комиссия
+  self.rate_value = calculate_finite_rate(base_rate_value, rate_percent)
+end
+```
+
+### 3. Формула расчета конечного курса
+
+**Файл:** `gera/app/models/concerns/gera/mathematic.rb`
+
+```ruby
+def calculate_finite_rate(base_rate, comission_percents)
+  base_rate * (1 - comission_percents / 100.0)

+
+1. **Настройки:**
+   - `position_from: 3`, `position_to: 5`
+   - `autorate_from: 1.0`, `autorate_to: 3.0`
+
+2. **Данные BestChange (позиции 2-4):**
+   - Позиция 3: комиссия 2.5%
+   - Позиция 4: комиссия 2.8%
+   - Позиция 5: комиссия 3.1%
+
+3. **Расчет `auto_comission_by_external_comissions`:**
+   - Фильтр по позиции: [2.5, 2.8, 3.1]
+   - Фильтр по комиссии (1.0-3.0): [2.5, 2.8]
+   - Первый: 2.5%
+   - Результат: 2.5 - 0.01 = **2.49%**
+
+4. **Добавляются корректировки по резервам и курсу (если настроены)**
+
+5. **Итоговая комиссия применяется к курсу:**
+   ```
+   finite_rate = base_rate * (1 - 2.49 / 100)
+   ```

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Gera is a Rails engine for generating and managing currency exchange rates for crypto changers and markets. It collects rates from external sources, builds currency rate matrices, and calculates final rates for payment systems with commissions.
+
+## Core Architecture
+
+### Rate Flow Hierarchy
+1. **ExternalRate** - Raw rates from external sources (EXMO, Bitfinex, Binance, CBR, etc.)
+2. **CurrencyRate** - Basic currency rates calculated from external rates using different modes (direct, inverse, cross)
+3. **DirectionRate** - Final rates for specific payment system pairs with commissions applied
+4. **ExchangeRate** - Configuration for commissions between payment systems
+
+### Key Models
+- **RateSource** - External rate providers with STI subclasses (RateSourceExmo, RateSourceBitfinex, etc.)
+- **PaymentSystem** - Payment systems with currencies and commissions
+- **CurrencyPair** - Utility class for currency pair operations
+- **Universe** - Central repository pattern for accessing rate data
+
+### Worker Architecture
+- **RatesWorker** concern for fetching external rates
+- Individual workers for each rate source (ExmoRatesWorker, BitfinexRatesWorker, etc.)
+- **CurrencyRatesWorker** - Builds currency rate matrix from external rates
+- **DirectionsRatesWorker** - Calculates final direction rates with commissions
+- **CreateHistory_intervalsWorker** - Aggregates historical data
+
+## Development Commands
+
+### Running Tests
+```bash
+# Run all tests
+bundle exec rake spec
+
+# Run specific test file
+bundle exec rspec spec/models/gera/currency_rate_spec.rb
+
+# Run with focus
+bundle exec rspec --tag focus
+```
+
+### Building and Development
+```bash
+# Install dependencies
+bundle install
+
+# Run dummy app for testing
+cd spec/dummy && rails server
+
+# Generate documentation
+bundle exec yard
+
+# Clean database between tests (uses DatabaseRewinder)
+```
+
+### Code Quality
+```bash
+# Lint code
+bundle exec rubocop
+
+# Auto-correct linting issues
+bundle exec rubocop -a
+```
+
+## Configuration
+
+Create `./config/initializers/gera.rb`:
+```ruby
+Gera.configure do |config|
+  config.cross_pairs = { kzt: :rub, eur: :rub }
+  config.default_cross_currency = :usd
+end
+```
+
+## Key Business Logic
+
+### Rate Calculation Modes
+- **direct** - Direct rate from external source
+- **inverse** - Inverted rate (1/rate)
+- **same** - Same currency (rate = 1)
+- **cross** - Calculated through intermediate currency
+
+### Supported Currencies
+RUB, USD, BTC, LTC, ETH, DSH, KZT, XRP, ETC, XMR, BCH, EUR, NEO, ZEC
+
+### External Rate Sources
+- EXMO, Bitfinex, Binance, GarantexIO
+- Russian Central Bank (CBR)
+- Manual rates and FF (fixed/float) sources
+
+## Testing Notes
+
+- Uses dummy Rails app in `spec/dummy/`
+- Factory Bot for test data in `factories/`
+- VCR for HTTP request mocking
+- Database Rewinder for fast test cleanup
+- Sidekiq testing inline enabled
+
+## File Organization
+
+- `app/models/gera/` - Core domain models
+- `app/workers/gera/` - Background job workers
+- `lib/gera/` - Core engine logic and utilities
+- `lib/builders/` - Rate calculation builders
+- `spec/` - Test suite with dummy app

-# Система Автокурса (AutoRate)
+# Система Автокурса (AutoRate) — Legacy
+
+> **Внимание:** Это документация **legacy-системы** расчёта курсов. Данная система используется в текущей production-версии, но планируется к замене.
+
+---
+
+## Краткое описание для бизнес-аналитика
+
+### Что это
+Система автоматически рассчитывает комиссию обменного направления, чтобы поддерживать конкурентную позицию в рейтинге BestChange.
+
+### Как формируется комиссия
+
+Итоговая комиссия = **Базовая** + **Корректировка по резервам** + **Корректировка по курсу**
+
+---
+
+**1. Базовая комиссия (по позиции в BestChange)**
+
+Оператор задаёт:
+- Целевой диапазон позиций (например, 3–5 место)
+- Допустимый диапазон комиссии (например, 1–3%)
+
+Система смотрит, какую комиссию ставят конкуренты на этих позициях, и ставит **на 0.01% ниже** первого подходящего — чтобы быть чуть выгоднее.
+
+---
+
+**2. Корректировка по резервам**
+
+Если резервов много → можно снизить комиссию (привлечь больше клиентов)
+Если резервов мало → повысить комиссию (снизить нагрузку)
+
+Настраивается через контрольные точки: "при отклонении резерва на X% — изменить комиссию на Y%"
+
+---
+
+**3. Корректировка по динамике курса**
+
+Сравнивается текущий курс со средним за 24 часа.
+При резких скачках курса комиссия корректируется для снижения рисков.
+
+---
+
+### Пример
+
+| Параметр | Значение |
+|----------|----------|
+| Целевая позиция | 3–5 место |
+| Допустимая комиссия | 1–3% |
+| Комиссия конкурента на 3 месте | 2.5% |
+| **Наша комиссия** | **2.49%** |
+
+Плюс корректировки по резервам и курсу, если настроены.
+
+---
+
+### Итог
+
+Система позволяет автоматически удерживать заданную позицию в рейтинге, при этом учитывая внутренние ограничения (резервы) и рыночные условия (волатильность курса).

Исправлена проблема с плавающей точкой при расчёте комиссии.
После вычитания GAP получались числа вида -2.8346999999999998.

- Добавлена константа COMMISSION_PRECISION = 4
- Добавлен метод round_commission() в Base
- Применено округление в PositionAware калькуляторе
- Добавлены тесты на округление
- Версия: 0.3.3 → 0.4.0

При position_from=1 если курс первой позиции совпадает с курсом
второй позиции — не вычитаем GAP. Позволяем BestChange определить
позицию по резервам/времени обновления.

- Добавлен метод should_skip_gap?
- Добавлена проверка в метод call
- Добавлены тесты для UC-12 и UC-11
- Версия: 0.4.0 → 0.4.1

Closes #77

Добавлено debug-логирование для отладки UC-11 на stage:
- Логирование входных параметров и промежуточных значений в call()
- Логирование в calculate_adaptive_gap() с выводом diff и выбранного GAP
- Логирование в adjust_for_position_above() с сравнением комиссий
- Логирование в find_non_anomalous_rate_above() с deviation для каждого курса

Конфигурация: Gera.autorate_debug_enabled = true (по умолчанию)
Логи помечены тегом [PositionAware] для удобного поиска.

- Исправлена логика UC-12: теперь работает для position_from > 1
- При одинаковых курсах на позициях position_from и position_from-1
  GAP не вычитается (BestChange определит позицию по резервам)
- Добавлены тесты UC-12 для position_from=1,2,3,5 в isolated_spec.rb
- Исправлены тесты: GAP = 0.0001 (не 0.001)
- Добавлен stub для PaymentServices::Base::Client (issue #78)
- Документация по запуску изолированных тестов в CLAUDE.md
- Bump version to 0.4.3

+### Запуск изолированных тестов автокурсов
+
+Для тестов автокурсов (PositionAware, Legacy калькуляторы) используются изолированные тесты,
+которые не загружают Rails и spec_helper. Это позволяет быстро тестировать логику без полной
+загрузки приложения.
+
+```bash
+# Переименовать .rspec чтобы не загружался spec_helper
+mv .rspec .rspec.bak
+
+# Запустить изолированные тесты
+mise exec -- bundle exec rspec spec/services/gera/autorate_calculators/isolated_spec.rb --no-color
+
+# Вернуть .rspec обратно
+mv .rspec.bak .rspec
+```
+
+Или используйте Makefile (требует БД):
+```bash
+make test  # запускает isolated_spec.rb и exchange_rate_spec.rb
+```
+
+**Важно:** Файл `isolated_spec.rb` самодостаточен и содержит все необходимые стабы для Gera модуля.
+

Тесты использовали неправильное значение GAP (0.001) вместо
фактического AUTO_COMISSION_GAP = 0.0001 из base.rb.

Изменения:
- position_aware_spec.rb: 0.001 → 0.0001 (9 мест)
- legacy_spec.rb: 0.001 → 0.0001 (2 места)
- standalone_spec.rb: 0.001 → 0.0001 (5 мест)

Обновлены комментарии для соответствия реальной логике.

Subject: [PATCH 136/156] fix: Simplify anomaly detection - UC-9 cancelled,
 UC-13 added
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #83

UC-9 (median-based anomaly filtering) has been cancelled because:
- Doesn't work correctly with negative commission rates
- Negative rates are now normal for competitive directions
- Median-based deviation was marking all top positions as anomalous

UC-13 (Protection from jumping above position_from - 1) is a simpler
approach that:
- Only compares with the immediate position above target range
- Prevents jumping above position_from - 1 regardless of "anomalies"
- Doesn't require complex median calculations

Когда позиция выше целевого диапазона отсутствует (rate_above = nil),
калькулятор теперь использует курс первой целевой позиции если он
в допустимом диапазоне autorate_from..autorate_to.

Это гарантирует что обменник не выйдет за пределы position_from
даже при отсутствии данных для позиций выше.

Closes #83

- Добавлен .compact перед .select для обработки nil в rates_in_target_position
- Удалён неиспользуемый параметр target_rate из fallback_to_first_target_position
- Исправлен комментарий UC-14: уточнено что fallback только для position_from > 1
- Исправлено имя теста: "корректирует до первой целевой позиции"

Критические исправления:
- Добавлен safe navigation (rate&.exchanger_id) в filtered_external_rates
- Добавлен try-catch в RateComissionCalculator с логированием и fallback
- Добавлен .compact в debug_log для rates_in_target_position

Важные улучшения:
- autorate_debug_enabled = false по умолчанию (избегаем спама в production)
- Исправлен комментарий "Гарантирует" → описание реального поведения
- Добавлен тест для случая first_target_rate = nil

 calculator_type validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add .compact before .select in Base#external_rates_in_target_comission
  to prevent NoMethodError on nil elements (fixes Legacy calculator edge case)
- Restore allow_nil: true for calculator_type validation to match
  autorate_calculator_class behavior which treats nil as 'legacy'

Subject: [PATCH 145/156] chore: Add missing UC tests and update documentation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add UC-6 tests (adaptive GAP) to isolated_spec.rb
- Add UC-8 tests (exclude our exchanger) to isolated_spec.rb
- Add UC-13 tests (prevent position jumping) to isolated_spec.rb
- Update doc/autorate_system.md with correct AUTO_COMISSION_GAP value (0.0001)

Test coverage now includes all UC cases in isolated tests:
- UC-1 through UC-5: basic scenarios
- UC-6: adaptive GAP for dense ratings
- UC-8: exclude our exchanger from calculation
- UC-12: skip GAP on equal rates
- UC-13: prevent jumping above target position
- UC-14: fallback to first target position

29 examples, 0 failures

Fixes #86

При position_from > 1 и rate_above = nil теперь ВСЕГДА возвращаем
first_target_rate.target_rate_percent, без условной проверки.

Изменения:
- fallback_to_first_target_position теперь всегда возвращает курс первой целевой позиции
- При first_target_rate = nil возвращаем autorate_from (было target_comission)
- Добавлено warn_log для отслеживания fallback событий
- MIN_GAP уменьшен до 0.00001 для корректной работы адаптивного GAP

- Добавить raise ArgumentError в filtered_external_rates при nil external_rates
- Добавить raise ArgumentError в round_commission при nil value
- Раскомментировать after_commit :update_direction_rates (регрессия)
- Убрать allow_nil: true из валидации calculator_type (противоречит NOT NULL)
- Удалить неиспользуемый could_be_calculated? из RateComissionCalculator

Subject: [PATCH 155/156] fix(issue-2291): allow same-to-same payment system
 directions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the `income_payment_system_id <> outcome_payment_system_id` filter
from ExchangeRate.available scope. This legacy restriction prevented 35
crypto same-to-same directions (e.g. USDT TRC20 → USDT TRC20) from
appearing in cs.json, making them unavailable on the frontend despite
being enabled in the admin panel and visible in valuta.xml/BestChange.

Unify available_for_parser as alias of available since both scopes are
now identical.

Fixes alfagen/mercury#2291
Issue: https://github.com/alfagen/mercury/issues/2291
