-## ADL-006: AGPL-3.0 Core + GPLv3 Plugin SDK for Licensing
-
-**Date:** 2025-12-20  
-**Updated:** 2025-12-28 (superseded)  
-**Status:** Superseded by ADL-013  
-**Context:**
-- EmberDocs aims to be free-to-self-host (core framework) with strong copyleft protection
-- Plugins (themes, integrations) should be community-extensible; encourage open-source contributions
-- Need to ensure network service providers share source code modifications
-
-**Decision:**
-- **Core framework:** AGPL-3.0 license, open source with strong copyleft (ensures network service providers share source code)
-- **Plugin SDK:** GPLv3 license; plugins must be open-source, but can integrate with proprietary code
-- **Licensed integrations:** Separate paid tier for official plugins/themes (future)
-
-**Alternatives Considered:**
-- Fully open-source (MIT): Strong community, but harder to monetize; no revenue for maintenance
-- Fully proprietary: Limits adoption and community plugins; not developer-friendly
-- Dual licensing (AGPL + commercial): Stronger copyleft, but can discourage enterprise adoption
-
-**Consequences:**
-- ✅ Free core appeals to developers and small teams
-- ✅ GPL plugins encourage community contributions while protecting against forks
-- ✅ Clear path to monetization via paid plugins/themes
-- ⚠️ GPL licensing may deter some commercial users (need clear legal guidance)
-- ⚠️ Requires discipline to categorize code as core vs. plugin

-## ADL-008: Plugin System — Minimal Hooks for MVP (4 Hooks)
-
-**Date:** 2025-12-23
-**Status:** Accepted
-**Context:**
-- EmberDocs needs extensibility for themes, custom transformers, and integrations
-- Risk: Too many hooks = scope creep; too few = plugins can't do useful things
-- MVP Phase 02 (Week 2) allocates limited time for plugin system design
-
-**Decision:**
-Implement 4 lifecycle hooks for MVP: `onBuild`, `onParseMD`, `onSearchIndex`, `onRender`.
-- `onBuild`: Runs at start of build; can generate assets or config
-- `onParseMD`: Transforms parsed Markdown AST (e.g., inject metadata, custom syntax)
-- `onSearchIndex`: Enriches search index (e.g., boost certain docs, add custom fields)
-- `onRender`: Post-processes rendered HTML (e.g., theme variants, inject analytics)
-
-**Design for Extensibility:** Use a hook registry pattern so v1.0 can add more hooks without breaking existing plugins. Example: `plugin.hooks.register('onBuild', callback)` instead of `plugin.onBuild = callback`.
-
-**Alternatives Considered:**
-- Minimal (2 hooks): Too restrictive; couldn't support common use cases
-- Rich (8+ hooks): Scope creep; delays Phase 02; overkill for MVP
-- None (no plugins yet): Misses extensibility opportunity; harder to retrofit later
-
-**Consequences:**
-- ✅ Covers 80% of plugin use cases (themes, metadata, search, rendering)
-- ✅ Scoped and shippable in Phase 02
-- ⚠️ Defers CLI commands, real-time webhooks, component system to v1.0
-- ⚠️ Requires sample plugins to validate design adequacy
-
-**Deferred to v1.0:** CLI hooks, theme system, component registration, real-time indexing.
