-Проверяй если код обрабатывает множество ассетов.
+Run through every item before merging code that calls `AssetDatabase.StartAssetEditing`, creates more than ten assets at once, or writes an `AssetPostprocessor`. Each bullet includes a verification command.
 
-- [ ] `AssetDatabase.StartAssetEditing()` обёрнут в `try/finally { StopAssetEditing(); Refresh(); }`
-- [ ] Progress bar для >10 ассетов: `EditorUtility.DisplayCancelableProgressBar()`
-- [ ] `ClearProgressBar()` в `finally`-блоке
-- [ ] Нет `AssetDatabase.Refresh()` внутри цикла — только после батча
-- [ ] `AssetPostprocessor` имеет bypass-множество (`HashSet<string>`) против рекурсии
-- [ ] `GetPostprocessOrder()` указан явно (не дефолтный 0)
-- [ ] Нет `AssetDatabase.ImportAsset()` внутри постпроцессора без bypass-защиты
+## Pre-batch
 
-## Эталонные реализации
+- [ ] A fresh `git status` shows no unrelated working-tree drift. Verify: `git status --porcelain`.
+- [ ] Every code path that opens a batch has a paired close in a `finally`. Verify: `grep -n "StartAssetEditing" path/to/file.cs` and confirm the same file contains the matching `StopAssetEditing` inside a `finally` block within the same method.
+- [ ] On Unity 6 or newer, prefer `using (new AssetDatabase.AssetEditingScope())` over manual Start/Stop. Verify: `grep -n "StartAssetEditing\|AssetEditingScope" .` and confirm the disposable form is used where `#if UNITY_6000_0_OR_NEWER` applies.
+- [ ] Queries against `AssetDatabase.LoadAssetAtPath`, `FindAssets`, or `GUIDToAssetPath` happen *before* opening the batch. Verify manually by reading the method top-to-bottom.
 
-- **Батчинг с try/finally:** prefabdoctor/Editor/Core/ProjectScanActions.cs — `BatchCreateWrappers()`, `BatchRemoveMissingScripts()`
-- **AssetPostprocessor с bypass:** unitymeshlab/Editor/Uv2AssetPostprocessor.cs
+## Mid-batch
+
+- [ ] No `AssetDatabase.Refresh()` appears inside the loop. Verify: `grep -n "Refresh()" path/to/file.cs` and confirm calls are outside the loop or removed entirely.
+- [ ] Progress bar (`EditorUtility.DisplayCancelableProgressBar`) is shown for any loop that iterates over more than ten assets. Verify by reading the loop body.
+- [ ] The user's cancel signal (`EditorUtility.DisplayCancelableProgressBar` return value) aborts the batch cleanly, still calling `StopAssetEditing` in `finally`.
+
+## Post-batch
+
+- [ ] `StopAssetEditing` is the first statement of the `finally` block; `ClearProgressBar` is second. Verify by reading.
+- [ ] A single `AssetDatabase.Refresh()` call occurs after the batch if new assets were written. Verify: `grep -c Refresh path/to/file.cs`.
+- [ ] Any generated asset path is reported via `UvtLog.Info` (or the package's logger) so the user can locate it. Verify: `grep -n "Log\|Debug.Log" path/to/file.cs`.
+
+## AssetPostprocessor-specific
+
+- [ ] The postprocessor declares a static `HashSet<string>` recursion guard populated in `try` and cleared in `finally`. Verify: `grep -n "HashSet<string>" path/to/*Postprocessor.cs`.
+- [ ] `GetPostprocessOrder()` returns an explicit integer, not the default `0`. Verify: `grep -n "GetPostprocessOrder" path/to/*Postprocessor.cs`.
+- [ ] `GetVersion()` returns an integer that increments whenever the postprocessor's behavior changes. Verify by reading and comparing to the previous git SHA.
+- [ ] No `AssetDatabase.ImportAsset` is called from inside the postprocessor without passing the path through the recursion guard.
+- [ ] On Unity 2021.2+, the `OnPostprocessAllAssets` overload accepts `bool didDomainReload`. Verify: `grep -n "OnPostprocessAllAssets" path/to/*Postprocessor.cs`.

+# Checklist: UPM package release
+
+Run through every item before tagging a release. Each bullet includes a verification command.
+
+## SemVer decision
+
+Choose exactly one bump based on the highest-impact change in the release:
+
+| Bump | Trigger |
+|---|---|
+| PATCH | Bug fixes, documentation, internal refactors. No public API change. |
+| MINOR | New public API, new asmdef, new sample, additive versionDefines. No breaking change. |
+| MAJOR | Any removed or renamed public type/member, Unity minimum bump, namespace change, asmdef name change. |
+
+- [ ] The SemVer bump matches the highest-impact change. Verify: `git log --oneline <previous-tag>..HEAD` and read every entry.
+- [ ] `package.json` `version` has been updated and committed. Verify: `jq -r .version package.json`.
+
+## CHANGELOG
+
+- [ ] `CHANGELOG.md` follows Keep-a-Changelog format with sections `Added` / `Changed` / `Deprecated` / `Removed` / `Fixed` / `Security`. Verify: `head -30 CHANGELOG.md`.
+- [ ] Every commit since the previous tag has a CHANGELOG entry, or is explicitly excluded as internal. Verify: diff `git log <previous-tag>..HEAD --oneline` against `CHANGELOG.md`.
+- [ ] The new version header matches `package.json` `version` exactly. Verify: `grep -n "^## \[" CHANGELOG.md | head -1`.
+
+## package.json
+
+- [ ] `name` is `com.sasharx.<package>` and matches the repository folder name. Verify: `jq -r .name package.json`.
+- [ ] `unity` field matches the declared minimum; `unityRelease` is set if a specific patch is required. Verify: `jq -r '.unity, .unityRelease' package.json`.
+- [ ] `repository.url` points to the canonical `https://github.com/SashaRX/<Repo>.git` URL. Verify: `jq -r .repository.url package.json` and compare to `git remote get-url origin`.
+- [ ] `dependencies` entries resolve in the latest Unity Package Manager. Verify: open in Unity and watch `Window > Package Manager` for resolve errors.
+- [ ] `samples` array entries correspond one-to-one to folders under `Samples~/`. Verify: `jq -r '.samples[].path' package.json | sed 's|^Samples~/||'` matches `ls Samples~`.
+- [ ] No non-standard fields (`type`, `main`, `module`) are present. Verify: `jq 'keys' package.json`.
+
+## Asmdef audit
+
+- [ ] Runtime asmdef has empty `includePlatforms` and empty `excludePlatforms`. Verify: `jq '.includePlatforms, .excludePlatforms' Runtime/*.asmdef`.
+- [ ] Editor asmdef has `includePlatforms: ["Editor"]`. Verify: `jq '.includePlatforms' Editor/*.asmdef`.
+- [ ] Test asmdef has `defineConstraints: ["UNITY_INCLUDE_TESTS"]`. Verify: `jq '.defineConstraints' Tests/**/*.asmdef`.
+- [ ] No Runtime asmdef references an Editor asmdef. Verify: `jq '.references' Runtime/*.asmdef` and confirm none end in `.Editor`.
+- [ ] `rootNamespace` of every asmdef matches the namespace used in the files under it. Verify by reading.
+
+## Documentation and license
+
+- [ ] `README.md` install-via-git-URL section points at the current default branch or tag. Verify: `grep -n "git\+https" README.md`.
+- [ ] `LICENSE` exists at the package root and its SPDX identifier matches `license` in `package.json`. Verify: `jq -r .license package.json` and `head -3 LICENSE`.
+- [ ] `Documentation~/` renders (index.md or TableOfContents present). Verify: `ls Documentation~` if present.
+
+## Build and tests
+
+- [ ] Compile passes on the declared minimum Unity version. Verify: CI result on the matrix minimum job.
+- [ ] Compile passes on the current LTS. Verify: CI result.
+- [ ] Every `#if UNITY_*` gate has an `#else` branch that compiles. Verify: `grep -rn "^#if UNITY_" Editor Runtime` and read each site.
+- [ ] EditMode tests pass. Verify: CI result, or `Window > General > Test Runner > Run All` in the editor.
+
+## Tag and publish
+
+- [ ] The git tag name matches `v<version>` exactly (e.g., `v1.2.3`). Verify: `git tag -l | tail`.
+- [ ] The tag points at HEAD of the default branch after CHANGELOG + version bump commits. Verify: `git log --oneline <tag> | head -1`.
+- [ ] Installation via `https://github.com/SashaRX/<Repo>.git` resolves the tagged version in a consumer project's `Packages/manifest.json`. Verify in a scratch Unity project.
