Claude.md tweaks

Aspire assigned random ports and an auto-generated Postgres password on each
run, so the fixed targets baked into local.runsettings and docker-compose
(localhost:5000/5173/5432, miccheck/password) didn't work when developing via
Aspire instead of docker compose. Pins Postgres user/password/port and the
api/admin HTTP endpoints so either workflow hits the same local addresses.

-Guidance for Claude Code (claude.ai/code) when working in this repo.
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
 
 ## Project
 
-MicCheck: open source. asp.net, c#, typescript, VueJS. Manages feature flags, projects, environments.
+MicCheck is an open source project written in asp.net, c#, typescript and VueJS that manages feature flags, their projects, and their environments. 
 
 ## Planned Structure
 
-- `src/admin/` — VueJS admin components
+- `src/admin/` — administrative components in VueJS
-- `src/api/` - .NET API + REST endpoints
+- `src/api/` - api and restful endpoints in .NET
 - `tests/` — test suite
 - `docs/` — documentation
 
 ## Best Practices
 
-- Use latest LTS .NET + latest supported nuget packages for that version
+- Ensure all projects are using the latest LTS version of .NET as well as the latest supported nuget packages for that .NET version
-- Set `langVersion` to latest in all csproj files; enable nullable
+- Ensure that langVersion is set to latest in all csproj files and nullable is enabled
-- Organize code by feature/area, not type (e.g. `features` namespace)
+- Code in all projects should be organized by feature or area instead of type.  (e.g. a features namespace with all feature related code in it or in child namespaces of it)
-- New features need unit tests covering as much logic as possible (both nunit and jest)
+- All new feature requests should include corresponding unit tests that cover as much of the logic as possible.
-- Any modified file: evaluate for missing test coverage and that all tests pass
+- Any file modified should be evaluated for potential test cases and missing coverage areas.
 
 # Coding

+- Use descriptive names for all classes and method created.  Avoid generic names like Provider, Manager, Helper
-- Match formatting/style from `.editorconfig`
+- Coding should match formating and style rules in the .editorconfig file
-- Wrap lines at 220 characters, leave single line if fewer
-- Place interfaces that are implemented by a single class at the bottom of the class file.  An interface with multiple implementations of an interface should be in a seperate file.
-- Do not use tuples for return types.  Prefer records or classes for multiple values
-- Do not use `sealed` 
-- Use `record` for data objects, `class` for objects with behavior. Avoid mutable state where possible.
 
 ## Testing
-- Require a minimum of 70% code coverage with a target of 90%.  Unit tests should focus on end-user scenarios first.
+- Write unit tests in a BDD style, testing as much code end-to-end as possible without without touching external resources like databases or file systems (e.g. WhenAUserDoesSomething_ThenAThingAppears)
-- Do not write tests for just to increase code coverage.  Call out lack of test coverage rather than covering something that isn't valuable to the end user.
+- Mock any external dependencies using Moq.
-- Code that can not be cleanly unit tested should be marked with [ExcludeFromCodeCoverage] or have it's namespace excluded from code coverage.
+- Do not name any mocked objects with the word Mock in them
-- BDD-style unit tests, end-to-end as possible, no external resources (DB, filesystem). e.g. `WhenAUserDoesSomething_ThenAThingAppears`
+- Do not include any Arrange / Act / Assert comments in the code

 ## Claude

+- Create all plans as .md file located in the `docs/` folder.  Admin in `docs/admin/` and API in `docs/api/`
-- Split large plans into discrete chunks — each buildable + committable independently
+- Divide up large plans into discrete chucks of functionality so each can be built and committed independently.
-- Plan generated from `docs/plans/<name>.md` → save as `docs/plans/<name>_plan.md`
