Summary

  • 3 bug fixes: cached object mutation, secrets_dir misclassification, missing super().post_init() call
  • 3 simplifications: removed namespace field, collapsed merge framework (10 classes -> 1 method), removed SettingsUtils facade
  • 2 cleanups: kwargs normalization, dead code removal
  • Net -1583 lines (480 added, 2063 removed), test suite 283/283 passing, 99% coverage
  • Architecture evaluation spec and implementation plan documented

Bug Fixes

  • SettingsManager.get_settings_object() now copies before applying runtime overrides (prevents cache mutation)
  • secrets_dir promoted to structural parameter in __hash__/__eq__ (was silently ignored)
  • super().post_init() restored in AppSettings (was commented out)

Breaking Changes

  • namespace field removed from SettingsParameters and MountainAshBaseSettings
  • SettingsUtils class removed — use SettingsFileHandler, SettingsKwargsHandler, and SettingsParameters.merge() directly
  • Merge framework classes removed (SettingsParameterMerger, FieldMergeUtils, GenericMerger, MergePriority) — use SettingsParameters.merge() instead

New

  • SettingsParameters.merge() classmethod replaces the entire merge framework
  • Design principles documented in mountainash-central (16 documents across architecture, usage, development)

Test plan

  • Full test suite: 283 passed, 0 failed
  • Coverage: 99%
  • Verify no downstream packages import SettingsUtils or namespace
  • Verify no downstream packages use SettingsParameterMerger or GenericMerger

This commit adds a new function called `clone_and_checkout` to the `.devcontainer/clone_repos.sh` script. This function is responsible for cloning and checking out branches of repositories. It takes two parameters: the repository owner and the repository name.

The function clones the repository using the provided owner and name, and then checks out the `develop` branch if it exists. If the `develop` branch is not found, it checks out the `main` branch instead. If neither branch is found, it stays on the default branch.

This function is used to clone and checkout a list of repositories specified in the script. Currently, only the `mountainash-utils-os` repository is being cloned and checked out.

This commit also adds a message to indicate that all repositories have been cloned and the appropriate branches have been checked out.

Removes outdated test files that have been superseded by the new comprehensive
test suite structure:

Removed Files:
- tests/test_settings_parameters.py (replaced by test_settings_parameters/ package)
- tests/database/_test_base_auth.py (deprecated auth testing)
- tests/secrets/test_*.py (5 files - deprecated secret management tests)
- tests/storage/_test_auth_storage_*.py (deprecated storage auth tests)
- src/mountainash_settings/settings/auth/__init__.py (empty deprecated file)

Rationale:
- Old test files used outdated patterns and fixtures
- New test suite provides superior coverage with better organization
- Deprecated auth/secrets/storage tests no longer align with current architecture
- Centralized fixtures eliminate need for scattered test implementations

Test coverage maintained and improved through new comprehensive test suite.

Update version from 25.5.1 to 25.8.0 to reflect new dotfile support feature.
Enhance FileTypeRegistry.identify() to recognize dotfiles (e.g., .env, .bashrc)
by checking if the filename starts with a dot and has no extension. This allows
proper identification of .env dotfiles without requiring a file extension.
Add temp_dotenv_file fixture and extensive unit and integration tests for:
- Dotfile identification (.env without extension)
- Dotfile vs extension file handling (.env dotfile vs .env extension)
- File separation and grouping with dotfiles
- Complete workflow integration tests
Replace platform-specific path handling with UPath cross-platform solution.
Removes dependency on mountainash-utils-os (get_platform_slash) in favor
of universal_pathlib UPath for better cross-platform path templating.

This commit adds a new function called `clone_and_checkout` to the `.devcontainer/clone_repos.sh` script. This function is responsible for cloning and checking out branches of repositories. It takes two parameters: the repository owner and the repository name.

The function clones the repository using the provided owner and name, and then checks out the `develop` branch if it exists. If the `develop` branch is not found, it checks out the `main` branch instead. If neither branch is found, it stays on the default branch.

This function is used to clone and checkout a list of repositories specified in the script. Currently, only the `mountainash-utils-os` repository is being cloned and checked out.

This commit also adds a message to indicate that all repositories have been cloned and the appropriate branches have been checked out.

Evaluates four architectural layers (caching, parameter split, merge framework,
template resolution) against correctness, predictability, and simplicity.
Identifies two P0 bugs and three P1 simplification opportunities.

Seven tasks covering P0 bugs (cached object mutation, secrets_dir
misclassification), P1 simplifications (namespace removal, merge
framework collapse, SettingsUtils removal), and P2 cleanup (kwargs
normalization, dead code removal).

…ngs_object()

Copy the cached instance before applying runtime override kwargs,
preventing silent data corruption where one caller's overrides
permanently alter the cached object for all subsequent callers.

secrets_dir is a configuration source (pydantic-settings reads from it),
not a runtime override. Two parameter sets with different secrets_dir
values must produce different cache entries.

Remove the legacy `namespace` field which served only as a cache
discriminator with no behavioral effect on settings loading. Cache
identity is now determined solely by config_files, settings_class,
env_prefix, and secrets_dir -- the parameters that actually affect
what values are produced.

Changes:
- Remove `namespace` from SettingsParameters dataclass, hash, eq,
  create(), to_dict(), and _init_namespace() static method
- Remove SETTINGS_NAMESPACE field from MountainAshBaseSettings
- Remove settings_namespace parameter from get_settings() functions
- Remove namespace from merge framework (merger and FieldMergeUtils)
- Remove namespace from SettingsUtils
- Rename is_namespace_initialised to is_initialised in SettingsManager
- Update all tests to use env_prefix for cache differentiation

Replace SettingsParameterMerger, FieldMergeUtils, GenericMerger,
MergePriority, get_merger, and 4 module-level functions with a single
SettingsParameters.merge() classmethod. Same per-field strategies
preserved: combine config files, validate class compatibility,
last-wins for scalars, merge dicts for kwargs.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Replace all SettingsUtils method calls with direct calls to
SettingsFileHandler, SettingsKwargsHandler, and SettingsParameters.merge().
SettingsUtils was a facade with only one-line delegations.

Remove defensive re-unwrapping of nested 'kwargs' key from merge logic.
Normalization now happens exactly once in create() via
SettingsKwargsHandler.format_kwargs_dict().

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Remove unreachable build_path_template(), commented-out legacy methods
from SettingsManager, and commented-out get_app_settings(). Clean up
docstrings and stale comments.

12 principle documents across 3 categories (architecture, usage,
development), following the established mountainash-expresions pattern.
Agent-first readability with reading order guidance.

The call was commented out (likely during debugging), causing
two test failures. The post_init hook chain requires subclasses
to call super().
