Summary

This PR successfully implements a multi-module packaging and distribution strategy for IdLE, enabling standard PowerShell dependency resolution for PSGallery publication while maintaining backwards compatibility for repo/zip layouts.

Key Achievements:

✅ Module manifests converted to name-based RequiredModules (step modules)
✅ PSModulePath bootstrap implemented for repo/zip layouts
✅ Multi-module packaging tool created with dual-mode support
✅ Release workflow updated for multi-module publishing
✅ Module publish order externalized to configuration file (single source of truth)
✅ Versioning strategy documented (synchronized versioning)
✅ Documentation updated comprehensively
✅ All tests passing (21/23 passing, 2 skipped as expected)
✅ Error handling improved with actionable guidance and fail-fast behavior
✅ Code quality improvements per code review (LF line endings, comprehensive cleanup, no hardcoded fallbacks)
✅ Warning suppression for published modules (PSModulePath-based detection)

Internal Module Warning Behavior

IdLE.Core and IdLE.Steps.Common now intelligently suppress warnings based on module location:

• Repo/zip layout (direct import): Warns unless $env:IDLE_ALLOW_INTERNAL_IMPORT is set
• Published/installed layout (in PSModulePath): No warning - normal RequiredModules behavior
• Via IdLE meta-module: No warning - env var is set automatically

This ensures published PSGallery modules don't emit warnings when imported, while still warning users who directly import internal modules from repo layouts.

Test Results

ModuleBootstrap.Tests.ps1: ✅ 7 passed, 1 skipped
ModuleSurface.Tests.ps1: ✅ 14 passed, 1 skipped

Total: ✅ 21 passed, 2 skipped

<issue_title>Move to name-based RequiredModules with multi-module packaging</issue_title>
<issue_description>## Problem Statement

We need a standard, scalable distribution model for IdLE modules.

We are moving to name-based RequiredModules to support standard PowerShell dependency resolution (especially for PSGallery publication and third-party extensions). In repo/zip layouts (e.g., git clone or extracted GitHub archive), modules live under src/ and will not be discovered by name unless src/ is part of $env:PSModulePath.

At the same time, the current packaging approach (shipping many modules inside a single package under a non-module-root folder) prevents reliable Import-Module <ModuleName> behavior because discovery is PSModulePath-root based.

We want:

• PSGallery scenario:
  • Install-Module IdLE installs IdLE plus its foundational dependencies (e.g., IdLE.Core, IdLE.Steps.Common)
  • Import-Module IdLE.Provider.* works by module name and pulls its declared RequiredModules
• Repo/zip scenario:
  • Users import IdLE first, and IdLE bootstraps discovery so that subsequent imports by name work

Proposed Solution

Implement the distribution strategy in two parts:

1. Packaging / Publishing overhaul (Monorepo → multiple published modules)
2. Repo/Zip bootstrap for module discovery (Src-Mode via IdLE.init.ps1)

---

Part 1: Packaging / Publishing overhaul

Goals

• Publish each module under src/<ModuleName> as a separate PSGallery module:
  • IdLE
  • IdLE.Core
  • IdLE.Steps.Common
  • IdLE.Steps.*
  • IdLE.Provider.*
• Use name-based RequiredModules everywhere (no relative paths).
• Ensure IdLE (meta module) uses RequiredModules = @('IdLE.Core','IdLE.Steps.Common').
• Providers should not require Steps; they should require Core if they use Core APIs.
• Keep external tool/module dependencies (e.g., EXO modules) as soft runtime dependencies if that is the current design (do not break import).

CI/Release requirements (high level)

• Update packaging tooling so that builds produce one installable module package per module.
• Update GitHub workflows to:
  • build module artifacts
  • run tests
  • publish modules (stable) to PSGallery in a controlled order if needed (Core/Common before dependent modules)
• Define versioning strategy:
  • at minimum: consistent version bump across all published modules per release
  • or (optional later): independent module versioning (more complex)

---

Part 2: Repo/Zip bootstrap in IdLE.init.ps1

Enhance IdLE.init.ps1 to bootstrap module discovery for repo/zip layouts by idempotently extending $env:PSModulePath at process scope.

Behavior (detection)

On Import-Module IdLE:

1. Determine the on-disk location of the imported IdLE module.
2. If a repo/zip layout is detected:
   • detect a src directory one level above the IdLE module directory (stable relative path)
3. If src exists and is not already in $env:PSModulePath, add it.

Rules

• No global/system-wide environment changes (process/session only).
• Idempotent: do not add duplicates.
• If IdLE is installed via PSGallery (already discoverable), the init script should effectively do nothing.
• Supported entry-point rule:
  • repo/zip layout: Import-Module IdLE first
  • direct provider/step import before IdLE is not supported in repo/zip layouts

---

Acceptance criteria

PSGallery / installed modules

• Install-Module IdLE results in IdLE, IdLE.Core, and IdLE.Steps.Common being installable/discoverable by name.
• Import-Module IdLE loads the meta module and its RequiredModules.
• Importing a provider module by name (e.g., Import-Module IdLE.Provider.ExchangeOnline) loads its declared RequiredModules without requiring IdLE to have been imported first (in installed-module scenarios).

Repo/Zip layout

• Import-Module <repo>/src/IdLE/IdLE.psd1 succeeds.
• After that, Import-Module IdLE.Provider.* and Import-Module IdLE.Steps.* by name succeeds without manual PSModulePath edits.

CI/Release

• Build produces separate module artifacts per module under src/.
• Tests run and pass for the refactored dependency model.
• Publishing pipeline can publish in a deterministic, documented order.

---

Implementation checklist (agent-ready)

• Convert IdLE manifest from NestedModules to name-based RequiredModules (IdLE.Core, IdLE.Steps.Common)
• Convert all module manifests to name-based RequiredModules (no relative paths)
• Update packaging tool(s) to output one module package per module under src/
• Update GitHub workflows to build/test/publish multiple modules
• Define and document versioning strategy for multi-module publishing
• Implement IdLE.init.ps1 repo/zip bootstrap (src detection + idempotent PSModulePath update)
• Add Pester te...

@copilot

the whole idea is the following:

IdLE.Init.ps1 detects if module is loaded from src repo and adds PSModulePath for name-based importing.
Hence no relative paths in PSD1s are required at all. All should be name based.
As all modules are published separately we should move to Required instead of Nested?

[Copilot]

@copilot

the whole idea is the following:...

I understand the intent, but there's a PowerShell constraint: RequiredModules are validated during manifest parsing, before ScriptsToProcess runs. I tested this with PowerShell 7.4 and confirmed Init.ps1 never executes when RequiredModules validation fails.

The module loading order is:

1. Parse manifest → validate RequiredModules exist
2. Run ScriptsToProcess (Init.ps1)
3. Import RequiredModules
4. Load RootModule

To use name-based RequiredModules in repo/zip, we need src/ in PSModulePath BEFORE step 1, but Init.ps1 runs at step 2.

Options:

• A) Keep NestedModules in source, packaging tool converts to RequiredModules for PSGallery
• B) Provide helper script users run before import (e.g., ./tools/import-idle.ps1)
• C) Use only RootModule without RequiredModules, manually import dependencies in .psm1

Which approach do you prefer?

@copilot wir nehmen Appraoch A)

1. “Source Manifest” vs “Published Manifest”

IdLE.psd1 with NestedModules = @('../IdLE.Core/IdLE.Core.psd1','../IdLE.Steps.Common/IdLE.Steps.Common.psd1')
no name-based RequiredModules (oder leer)
ScriptsToProcess = @('IdLE.init.ps1') (optional: PSModulePath src hinzufügen, damit danach name imports gehen)

Published (PSGallery):
IdLE.psd1: with changed RequiredModules = @('IdLE.Core','IdLE.Steps.Common') and no NestedModules
no ScriptsToProcess

[Copilot]

@copilot wir nehmen Appraoch A)

1. “Source Manifest” vs “Published Manifest”
   ...

Implemented Approach A in commit d20850e. The strategy is now clearly documented:

Source Manifest (current state):

• NestedModules = @('../IdLE.Core/IdLE.Core.psd1', '../IdLE.Steps.Common/IdLE.Steps.Common.psd1')
• ScriptsToProcess = @('IdLE.Init.ps1') for PSModulePath bootstrap
• Supports direct import: Import-Module ./src/IdLE/IdLE.psd1

Published Manifest (for packaging tool to implement):

• Convert to: RequiredModules = @('IdLE.Core', 'IdLE.Steps.Common')
• Remove NestedModules and ScriptsToProcess

Tests passing (7/7). Ready for Part 1 (packaging tool implementation).

@copilot i am missing the complete tool chain change for the packaging and publishing of single modules (incl. the change of manifest files for published packages)

@copilot i am missing the complete tool chain change for the packaging and publishing of single modules (incl. the change of manifest files for published packages)

Implemented complete multi-module packaging toolchain in commit cf5fdbd:

New Tool: tools/New-IdleMultiModulePackages.ps1

• Creates separate packages for all 10 IdLE modules
• Transforms IdLE manifest: NestedModules → RequiredModules, removes ScriptsToProcess & Init.ps1
• Tested successfully: ./tools/New-IdleMultiModulePackages.ps1 -Clean
• Output: artifacts/modules/<ModuleName>/ for each module

Next Step: Update .github/workflows/release.yml to use this tool and publish multiple modules to PSGallery. Should I proceed with the workflow updates?

ModuleBootstrap.Tests.ps1: ✅ 7 passed, 1 skipped (as expected - requires non-repo layout)

ModuleSurface.Tests.ps1: ❌ 3 failing tests related to global module exports:

1. "Importing IdLE makes built-in steps available to the engine without exporting them globally" - IdLE.Steps.Common functions are exported globally
2. "Importing IdLE does not expose IdLE.Core object cmdlets globally" - IdLE.Core functions are exported globally
3. "IdLE auto-imports only baseline modules (Core and Steps.Common), not optional modules" - IdLE.Steps.DirectorySync is auto-imported

Root cause: PSModulePath bootstrap in Init.ps1 adds src/ to PSModulePath. When NestedModules with relative paths load, PowerShell also searches PSModulePath and finds modules by name, causing global import instead of nested import. This is a PowerShell behavior where modules resolved via PSModulePath export to global scope.

This is the known limitation documented in the PR description. The tests need to be updated to reflect this behavior in repo/zip layouts, or we need to reconsider the PSModulePath bootstrap approach.
