+**gclo** is a Windows 11 desktop app (WinUI 3) plus a CLI that clone and update every
+repository of a GitHub organization or user account. It conforms to the
 [KofTwentyTwo standards](https://github.com/KofTwentyTwo/standards) (Product tier);
 this file is the agent instruction file those standards ask for (K22-AI-40).
 
 ## Build, test, lint

-Line coverage must stay at 100% on `gclo.Engine`, `gclo.ViewModels`, and `gclo` (the
-CLI). Tests stay offline (fakes in `gclo.Engine.Tests/Fakes.cs`; the UI suite uses the
-`GCLO_UITEST_FIXTURE` seam).
+One class or one test (xunit 2, VSTest filter):
+
+```powershell
+dotnet test gclo.Engine.Tests --filter "FullyQualifiedName~OrgSyncEngineTests"
+dotnet test gclo.Cli.Tests --filter "FullyQualifiedName~SyncCommandTests.<MethodName>"
+```
+
+- The engine, view models, CLI, and their tests need only the .NET 10 SDK (`global.json`);
+  the app needs the Windows App SDK / WinUI workload. Run the CLI from source with
+  `dotnet run --project gclo.Cli -- <command>`.
+- The app is always built unpackaged and self-contained: `gclo.csproj` fixes
+  `WindowsPackageType=None` and `WindowsAppSDKSelfContained=true`, so the
+  `-p:WindowsPackageType=None` seen in older docs and CI is a no-op. Do not add APIs
+  that need package identity.
+- CI also runs PSScriptAnalyzer over `packaging/chocolatey/tools`.
+- Git hooks: `pre-commit install --hook-type pre-commit --hook-type commit-msg` (secrets,
+  workflow lint, format gate, Conventional Commit header, DCO sign-off, no commit to `main`).
+
+### Local build traps
+
+- **CRLF working tree breaks the build.** Text is LF (`.gitattributes`, `.editorconfig`).
+  A checkout whose `.cs` files are CRLF (`git ls-files --eol` shows `w/crlf`) fails with
+  `IDE0055: Fix formatting` on multi-line expressions. A fresh `git worktree` checks out
+  LF. Edits from scripts must not re-introduce CRLF; a new file written by a Windows
+  tool is CRLF until it is checked out again from the index.
+- **Lock files and the SDK.** `Directory.Build.targets` pins the implicit
+  `Microsoft.NET.ILLink.Tasks` package (the single-file analyzer), which would
+  otherwise follow the installed SDK patch and break the locked restore on every SDK
+  update. Keep the pin at the version bundled with the SDK named in `global.json`,
+  never newer. A restore that still rewrites `packages.lock.json` means a real
+  dependency change: commit it deliberately or revert it.
+
+### Tests
+
+- `gclo.Engine.Tests` covers **both** `gclo.Engine` and `gclo.ViewModels`;
+  `gclo.Cli.Tests` covers the CLI, whose assembly is named `gclo` (it ships as
+  `gclo.exe`), so it appears as package `gclo` in coverage reports.
+- Line coverage must stay at **100%** on those three assemblies (`coverage.runsettings`
+  scopes it; the CI gate reads the cobertura reports). The only exclusions are
+  source-generated code and types marked `[ExcludeFromCodeCoverage(Justification = ...)]`:
+  the thin adapters over things that cannot run offline (`LibGit2GitClient`,
+  `OctokitGateway`, `ProcessRunner`) and the CLI composition roots. Do not widen that
+  set to pass the gate; put logic behind a seam and test it.
+- Tests stay offline: fakes in `gclo.Engine.Tests/Fakes.cs`, real on-disk git fixtures
+  via `GitTestHelpers` (Windows-invalid tree entries are forged through the object
+  database), console capture in `gclo.Cli.Tests/CliTestSupport.cs`. No network, no real
+  tokens.
+- `gclo.UiTests` drives the built `gclo.exe` out of process with FlaUI/UIA and needs an
+  interactive desktop. It has no project reference to the app: build the app first, or
+  set `GCLO_UITEST_EXE`. Each session launches with a temp `GCLO_DATA_DIR` and
+  `GCLO_UITEST_FIXTURE=1`; all tests run sequentially in shared-session collections
+  (`[Collection(nameof(UiSessionTests))]`, which xunit does not inherit from the base
+  class). Elements are found by `AutomationId`. The suite needs the desktop to itself:
+  runs made while someone uses the machine time out in unrelated tests. Under the
+  fixture the app opens no email program and leaves the clipboard alone, because
+  both belong to the machine the suite runs on.
+
+## Architecture
+
+```
+gclo (WinUI 3 shell) ─┐
+                      ├─> gclo.ViewModels ─> gclo.Engine ─> Octokit, LibGit2Sharp
+gclo.Cli (gclo.exe) ──┘
+```
+
+Flat layout, no `src/` or `tests/` (ADR 0005). `gclo.Engine` + `gclo.ViewModels`
+together are the "Core": all logic lives there, under the coverage gate.
+
+- **`gclo.Engine`** is a published NuGet library, so its public surface and namespace
+  are a compatibility contract, every public member is documented (CS1591 is on), and
+  `ConfigureAwait(false)` is required (MA0004 is an error here only). `OrgSyncEngine`
+  takes an `IRepositoryLister` and an `IGitClient`, resolves every target folder
+  through `RepositoryPathResolver` (a repo name must be exactly one safe path segment),
+  then runs the set through `Parallel.ForEachAsync`. **Per-repo failure isolation is
+  exception-based**: the loop body catches everything except cancellation, so each repo
+  ends in exactly one terminal `SyncStatus` (Done, Failed, Canceled) reported through
+  `IProgress<RepoProgress>`. Pulls are fast-forward only.
+- **GitHub access** is layered: `GitHubRepositoryLister` / `GitHubOrganizationLister`
+  (paging and translation of Octokit exceptions into `GitHubAccessException`, which is
+  the tested logic) over the internal `IGitHubGateway` seam, implemented by the
+  uncovered `OctokitGateway`.
+- **Windows-invalid paths**: `LibGit2GitClient` validates the incoming tree with
+  `WindowsPathValidator` *before* checkout. On a hit it throws
+  `InvalidRepositoryPathsException`, keeps the fetched `.git`, and leaves a
+  pending-checkout marker inside it so a partial tree is never taken for up to date.
+  `IGitClient.ApplyRecoveryAsync` then materializes the tree with a `PathRecovery`
+  (renames and skips), which is persisted and re-applied on later pulls. `WslCloner`
+  (over `IProcessRunner`) is the alternative recovery.
+- **`gclo.ViewModels`** is UI-framework-free (CommunityToolkit.Mvvm, partial-property
+  form). `WorkspaceViewModel` is one workspace (Quick Sync or a saved account): load,
+  filter and select, sync, retry, path recovery. Engine progress reaches it through
+  `BatchedRepoProgress` (a few deliveries a second, the latest report per repository;
+  one dispatcher callback per report froze the window on large runs). The table the
+  view binds is `FilteredRepos`, kept in order row by row (`PlaceInTable`,
+  `CompareForTable`): the user's column, or the default order that follows a sync
+  (in flight, failed, finished latest first, waiting; idle: failed, then by name).
+  `TableOrderTests` states that rule independently; change both together.
+  `SyncAllCoordinator` runs account workspaces one at a time and drives
+  `SyncAllStatus`, which the shell shows above the workspace.
+  `ResponsivenessMonitor` writes to the activity log when the window did not respond.
+  `ShareInvitation` builds the Help > Share email. Persistence also lives here: `GcloPaths.DataRoot` is the
+  single seam for per-user data (`%LOCALAPPDATA%\KofTwentyTwo\gclo`, overridden by
+  `GCLO_DATA_DIR`, and deliberately not the Velopack install root, which Setup.exe
+  deletes); `AppSettings` → `settings.json`; `AccountsStore` → `accounts.json`
+  (metadata only) with tokens in an `ITokenVault` (`CredentialManagerVault`, or
+  `InMemoryVault`). The file and the vault have no shared transaction, so every
+  operation touching both has a fixed order and a compensating step: keep that when
+  changing `AccountsStore`.
+- **`gclo.Cli`**: `Program` dispatches to `SyncCommand`, `ReposCommand`, `OrgsCommand`,
+  `AccountsCommand`. Each has a thin public entry that wires the real collaborators
+  (excluded from coverage) and an `internal` core that takes them as parameters, which
+  is what the tests call. Exit codes are in `ExitCodes` and documented in `docs/CLI.md`.
+  JSON output goes through source-generated contexts (`CliJsonContext`), so a new
+  serialized type must be registered there.
+- **`gclo`** (the app) holds XAML, dialogs, pickers, and update plumbing only.
+  `MainWindow.xaml.cs` is the composition root: it builds the vault, the store, and
+  every `WorkspaceViewModel`, wrapping the real listers and git client in
+  `UiTestFixture`, which answers from a fixed offline organization only when
+  `GCLO_UITEST_FIXTURE=1` **and** the token is the fixture's magic token. `Program.cs`
+  replaces the XAML-generated `Main` so `VelopackApp.Build().Run()` executes first, and
+  switches `GcloPaths.Edition` to `dev` for the `gclo-dev` app id (the dev channel
+  installs beside stable with its own data root). `ImplicitUsings` is off in this
+  project only. Handlers and `x:Bind` targets look unused to analyzers; the relaxations
+  in `.editorconfig` for `gclo/**.cs` exist so `dotnet format` does not delete them.
+- **Releases** are tag-driven (`v*`) through the standards' shared Velopack workflow:
+  see `docs/RELEASING.md`. `bucket/gclo.json` (this repo is its own Scoop bucket) and
+  `packaging/chocolatey` are regenerated by the release's `packages` job.
