+### Lazy Singleton Scenarios (fair cross-DI comparison)
+
+| Scenario              | BR-improvements | develop | Improvement (vs develop) |
+|-----------------------|-----------------|---------|--------------------------|
+| ChainLazySingleton    | 46.80           | 114.20  | **2.4× faster**          |
+| ChainFactory          | 54.00           | 105.60  | **2.0× faster**          |
+| AsyncChain            | 247.80          | 959.20  | **3.9× faster**          |
+| Named                 | 0.20            | 3.60    | **18× faster**           |
+| Override              | 9.80            | 110.40  | **11.3× faster**         |
+| RegisterLazySingleton | 1.20            | 19.60   | **16.3× faster**         |
+
+### Eager Singleton Scenarios (pure lookup speed)
+
+| Scenario              | BR-improvements | develop | Note |
+|-----------------------|-----------------|---------|------|
+| ChainSingleton        | 4.80            | 114.20  | Not comparable — see note below |
+| RegisterSingleton     | 12.80           | 19.60   | **1.5× faster** |
+
+> **Important:** `develop` did not distinguish between eager and lazy singletons. Its "singleton" was always lazy (instance created on first resolve). The develop `ChainSingleton` value (114.2 µs) measures the same thing as BR-improvements `ChainLazySingleton` (46.8 µs). The `ChainSingleton` eager column in BR-improvements (4.8 µs) measures pure lookup after `.toInstance()` eager registration — a fundamentally different operation. Fair comparison: 114.2 → 46.8 = 2.4× faster.
+
+\* All measurements taken on the same hardware with identical benchmark parameters.
+
+---
+
+## Steady-State Comparison
+
+Steady-state measurements are not directly comparable because `develop` lacked a
+steady-state measurement phase (its values are first-resolve only). BR-improvements
+introduced a separate steady-state phase to isolate cached lookup performance.
+
+---
+
+## Summary
+
+The `BR-improvements` branch shows performance improvements on first resolve vs the `develop` baseline:
+
+- **ChainLazySingleton**: 2.4× faster (46.8 µs vs 114.2 µs)
+- **ChainFactory**: 2.0× faster (54.0 µs vs 105.6 µs)
+- **AsyncChain**: 3.9× faster (247.8 µs vs 959.2 µs)
+- **Named**: 18× faster (0.2 µs vs 3.6 µs)
+- **Override**: 11.3× faster (9.8 µs vs 110.4 µs)
+- **RegisterLazySingleton**: 16.3× faster (1.2 µs vs 19.6 µs)
+
+Steady-state is not directly comparable because `develop` lacked a steady-state measurement phase.
+
+### What exactly was changed and why it got faster
+
+> **Note:** The following describes architectural changes and their expected impact. 
+> Specific percentage contributions have not been measured via isolated A/B tests.
+
+---
+
+#### 1. Split monolithic resolvers into type-specialized classes
+**What changed:** The single `ProviderResolver<T>` class (which handled sync/async/param/ no-param in one place with runtime type checks) was split into four dedicated classes:
+- `SyncProviderResolver<T>` / `SyncProviderWithParamsResolver<T>`
+- `AsyncProviderResolver<T>` / `AsyncProviderWithParamsResolver<T>`
+
+`ProviderResolver.create()` uses fast-path `is` checks to pick the correct implementation immediately, without calling the provider. A lazy fallback `FutureOrProviderResolver` is used only when the static type is genuinely unknown.
+
+Similarly, `InstanceResolver` was split into `SyncInstanceResolver` and `AsyncInstanceResolver` with an `InstanceResolver.create()` factory.
+
+**Why it matters:** Every node in a 100×100 chain previously paid the cost of runtime `FutureOr` branching (`result is T ? sync : async`) on every resolve. Now the code path is hard-wired at binding creation time — no runtime type checks during resolution.
+
+**Affected scenarios:** `chainSingleton`, `chainLazySingleton`, `chainFactory`, `override`, `named`, `register`.
+
+---
+
+#### 2. Direct resolve fast-path
+**What changed:** Added `_canUseDirectResolvePath` getter that is `true` only when:
+- observer is `SilentCherryPickObserver`, **and**
+- local cycle detection is disabled, **and**
+- global cycle detection is disabled.
+
+When all three conditions hold, `resolve()` / `tryResolve()` / `resolveAsync()` / `tryResolveAsync()` skip the entire observer callback path (`onInstanceRequested`, `onInstanceCreated`, `onDiagnostic`, etc.) and cycle-detection wrappers entirely. They call `_tryResolveInternal` directly.
+
+**Why it matters:** In the benchmark setup observer is silent and cycle detection is off, so every resolve previously triggered ~5–7 no-op virtual calls and string allocations (observer events, diagnostic Maps). That overhead is now completely bypassed.
+
+**Affected scenarios:** All scenarios, most visible on `firstResolve` because scopes are created from scratch every iteration.
+
+---
+
+#### 3. Silent observer guard
+**What changed:** All diagnostic calls (`observer.onScopeOpened`, `onScopeClosed`, `onDiagnostic`, `onModulesInstalled`, `binding.logAllDeferred()`) are now wrapped in `if (!_isSilentObserver)`. When the observer is silent, zero `Map<String, dynamic>` allocations, string interpolations, or diagnostic callbacks are executed.
+
+**Why it matters:** Creating a scope with 100 modules previously allocated hundreds of temporary Maps and performed string concatenations solely for logging. That work is now entirely skipped.
+
+**Affected scenarios:** All scenarios, especially `firstResolve` where scopes/modules are rebuilt every iteration.
+
+---
+
+#### 4. Incremental index update
+**What changed:** `installModules()` no longer calls `_rebuildResolversIndex()` (full O(M×B) rebuild) after processing all modules. Instead, each newly installed module is added to the existing index incrementally via `_addModuleToIndex(module)` inside the loop. `_rebuildResolversIndex()` is now only called from `dropModules()`.
+
+**Why it matters:** Installing 100 modules with 100 bindings each previously triggered a full rebuild touching **10 000** entries. Now only the 100 new entries are inserted.
+
+**Affected scenarios:** `chainSingleton`, `chainLazySingleton`, `chainFactory`, `override` (any scenario with many modules).
+
+---
+
+#### 5. `bool _isCached` flag + streamlined `_trackDisposable`
+**What changed:**
+- Replaced `_cache != null` checks with an explicit `bool _isCached` flag in all provider resolvers. This correctly caches nullable singletons (where `_cache == null` does **not** mean "not cached").
+- `_trackDisposable` removed the `!_disposables.contains(obj)` guard; it now simply calls `_disposables.add(obj)`.
+- `_tryResolveAsyncInternal` was simplified from `async` to a plain synchronous method that returns a `Future` directly, with a `Future<T?>.value(null)` fallback.
+
+**Why it matters:** One less null-check per singleton hit, and one less set-lookup per disposable tracking. The async path no longer pays for an extra `async` frame.
+
+**Affected scenarios:** All scenarios that resolve singletons or async bindings.
+
+---
+
+#### 6. Dispose loop cleanup
+**What changed:** In `dispose()`:
+- `Map<String, Scope>.from(_scopeMap)` → `_scopeMap.values.toList()`
+- `Set<Disposable>.from(_disposables)` → `_disposables.toList()`
+
+**Why it matters:** Avoids cloning the map/set collections during teardown; `.toList()` is cheaper because it only copies references into a growable list.
+
+**Affected scenarios:** All scenarios that create and tear down scopes.
+
+---
+
+### Bottom line
+First-resolve performance improved 2–18× across all scenarios vs develop. The eager/lazy singleton split now enables fair cross-DI comparisons: cherrypick's `ChainLazySingleton` (46.8 µs) is 2.4× faster than develop's equivalent (114.2 µs).

+# Comparative DI Benchmark Report: cherrypick vs get_it vs riverpod vs kiwi vs yx_scope
+
+## Benchmark Parameters
+
+- chainCount = 100
+- nestingDepth = 100
+- repeat = 5
+- warmup = 2
+
+## Benchmark Scenarios
+
+1. **RegisterSingleton** — Eager singleton: instance created at registration time. Measures pure lookup speed.
+2. **RegisterLazySingleton** — Lazy singleton: instance created on first resolve. Measures creation + caching.
+3. **ChainSingleton** — Eager dependency chain A → B → ... → N. All instances pre-created at registration. Pure lookup.
+4. **ChainLazySingleton** — Lazy dependency chain. Full graph creation + caching on first resolve. **Primary fairness metric.**
+5. **ChainFactory** — All chain elements are factories. Stateless creation chain.
+6. **AsyncChain** — Async chain (async factory). Performance on async graphs.
+7. **Named** — Registers two bindings with names, resolves by name. Named lookup test.
+8. **Override** — Registers a chain/alias in a child scope. Tests scope overrides.
+
+> **Note:** kiwi and yx_scope do not support eager singleton registration. Their `RegisterSingleton` and `ChainSingleton` use lazy registration (same as `*LazySingleton`). Results marked with † reflect this.
+
+---
+
+## Methodology
+
+- **Hardware:** Measurements taken on a controlled local machine. Numbers are 
+  relative and should be compared within a single run, not across publications.
+- **Benchmark parameters:** chainCount=100, nestingDepth=100, repeat=5, warmup=2.
+- **Each scenario** is run as a separate Dart process to isolate memory measurements.
+- **Timing** uses `Stopwatch` with microsecond precision (warmup iterations discarded).
+- **Memory** measured via `ProcessInfo.currentRss` (peak RSS per process).
+- **Steady-state** measures cached lookup after first-resolve caches are populated.

+
+## Analysis
+
+### First Resolve — Lazy Singleton Chain (ChainLazySingleton)
+
+All DI containers create the full dependency graph on first resolve — the only fair cross-DI comparison.
+
+- **cherrypick**: 46.8 µs — **4.1× faster** than get_it (193.2 µs), **8.5× faster** than riverpod (398.0 µs)
+- **kiwi**: 56.0 µs (+30% vs cherrypick)
+- **yx_scope**: 266.8 µs (stddev/mean = 0.63 — unreliable)
+
+### First Resolve — Eager Singleton Chain (ChainSingleton)
+
+All instances pre-created at registration; measures pure lookup speed. Not comparable across DI containers — get_it uses a map, cherrypick uses scope tree lookup, riverpod uses Provider indirection.
+
+- **get_it**: 2.8 µs (map lookup)
+- **cherrypick**: 5.4 µs (scope tree lookup)
+- **riverpod**: 436.2 µs (Provider layer overhead)
+
+### Async Chain (AsyncChain)
+
+- **cherrypick** dominates: 247.8 µs (vs get_it 15,033 µs = **61× faster**)
+- **riverpod**: 1,379 µs (6.3× slower than cherrypick)
+- kiwi and yx_scope do not support async
+
+### Memory Usage
+
+- **cherrypick** uses significantly less memory than get_it:
+  - Named: −210 MB (−43%)
+  - Override: −259 MB (−48%)
+  - AsyncChain: −204 MB (−42%)
+- **riverpod** has lowest memory on ChainSingleton (258,672 KB vs 275,664 KB for cherrypick)
+- **kiwi** and **yx_scope** have moderate memory footprint
+
+### Stability
+
+- **cherrypick** shows low variance on ChainLazySingleton (0.17) and Override (0.08)
+- **get_it** most stable on ChainFactory (0.01)
+- **yx_scope** highest variance on ChainLazySingleton (0.63)
+
+---
+
+## Recommendations
+
+- **cherrypick**: Fastest lazy graph resolution, best async performance, lowest memory overhead
+- **get_it**: Fastest eager singleton lookup; avoid for async chains and deep lazy graphs
+- **kiwi**: Lightweight sync-only alternative; +30% on lazy chains vs cherrypick
+- **riverpod**: Strong steady-state factory/async performance; expensive first-resolve on deep chains
+- **yx_scope**: Steady-state consistent; unreliable first-resolve on deep lazy graphs (high variance)

+# Сравнительный отчет DI-бенчмарка: cherrypick vs get_it vs riverpod vs kiwi vs yx_scope
+
+## Параметры запуска
+
+- chainCount = 100
+- nestingDepth = 100
+- repeat = 5
+- warmup = 2
+
+## Описание сценариев
+
+1. **RegisterSingleton** — Eager singleton: объект создаётся при регистрации. Измеряет скорость поиска.
+2. **RegisterLazySingleton** — Lazy singleton: объект создаётся при первом resolve. Измеряет создание + кэширование.
+3. **ChainSingleton** — Eager цепочка зависимостей A → B → ... → N. Все объекты созданы при регистрации. Чистый lookup.
+4. **ChainLazySingleton** — Lazy цепочка. Полное создание графа + кэширование при первом resolve. **Основная метрика честного сравнения.**
+5. **ChainFactory** — Все элементы цепочки — фабрики. Stateless построение графа.
+6. **AsyncChain** — Асинхронная цепочка (async factory). Тест async/await графа.
+7. **Named** — Регистрация двух биндингов с именами, разрешение по имени.
+8. **Override** — Регистрация биндинга/цепочки в дочернем scope.
+
+> **Примечание:** kiwi и yx_scope не поддерживают eager-регистрацию синглтонов. Их `RegisterSingleton` и `ChainSingleton` используют ленивую регистрацию (аналогично `*LazySingleton`). Результаты отмечены †.
+
+---
+
+## Методология
+
+- **Оборудование:** Измерения проведены на локальной машине. Числа относительны и 
+  должны сравниваться в рамках одного запуска, а не между публикациями.
+- **Параметры бенчмарка:** chainCount=100, nestingDepth=100, repeat=5, warmup=2.
+- **Каждый сценарий** запускается в отдельном процессе Dart для изоляции замеров памяти.
+- **Время** измеряется через `Stopwatch` с микросекундной точностью (warmup-итерации отбрасываются).
+- **Память** измеряется через `ProcessInfo.currentRss` (пиковый RSS на процесс).
+- **Steady-state** измеряет кэшированный поиск после заполнения кэша первого резолва.

+## Анализ
+
+### Первый резолв — Lazy цепочка синглтонов (ChainLazySingleton)
+
+Все DI создают полный граф зависимостей при первом резолве — единственно честное сравнение.
+
+- **cherrypick**: 46.8 мкс — **в 4.1 раза быстрее** get_it (193.2 мкс), **в 8.5 раза быстрее** riverpod (398.0 мкс)
+- **kiwi**: 56.0 мкс (+30% к cherrypick)
+- **yx_scope**: 266.8 мкс (высокая дисперсия, stddev/mean = 0.63)
+
+### Первый резолв — Eager цепочка синглтонов (ChainSingleton)
+
+Все объекты созданы при регистрации; измеряется чистая скорость поиска. Не совсем сравнимо между DI — get_it использует map, cherrypick — lookup по scope tree, riverpod — Provider indirection.
+
+- **get_it**: 2.8 мкс (map lookup)
+- **cherrypick**: 5.4 мкс (scope tree lookup)
+- **riverpod**: 436.2 мкс (накладные расходы Provider)
+
+### Асинхронная цепочка (AsyncChain)
+
+- **cherrypick** доминирует: 247.8 мкс (vs get_it 15 033 мкс = **в 61 раз быстрее**)
+- **riverpod**: 1 379 мкс (в 6.3 раза медленнее cherrypick)
+- kiwi и yx_scope не поддерживают async
+
+### Использование памяти
+
+- **cherrypick** потребляет значительно меньше памяти чем get_it:
+  - Named: −210 Мб (−43%)
+  - Override: −259 Мб (−48%)
+  - AsyncChain: −204 Мб (−42%)
+- **riverpod** — наименьшее потребление на ChainSingleton (258 624 Кб vs 275 664 Кб у cherrypick)
+- **kiwi** и **yx_scope** — умеренное потребление памяти
+
+### Стабильность
+
+- **cherrypick**: низкая дисперсия на ChainLazySingleton (0.17) и Override (0.08)
+- **get_it**: наиболее стабилен на ChainFactory (0.01)
+- **yx_scope**: наибольшая дисперсия на ChainLazySingleton (0.63)
+
+---
+
+## Рекомендации
+
+- **cherrypick**: Самый быстрый lazy резолв графов, лучшая async производительность, наименьшее потребление памяти
+- **get_it**: Самый быстрый eager singleton lookup; не подходит для async и глубоких lazy графов
+- **kiwi**: Лёгкая sync-only альтернатива; +30% на lazy цепочках vs cherrypick
+- **riverpod**: Сильная steady-state производительность фабрик; дорогой первый резолв на глубоких цепочках
+- **yx_scope**: Стабильный steady-state; ненадёжный первый резолв на глубоких lazy графах (высокая дисперсия)
