## Modules

- [PhoenixKitOG](PhoenixKitOG.md): OpenGraph template + hierarchical assignment plugin for PhoenixKit.
- [PhoenixKitOG.ActivityLog](PhoenixKitOG.ActivityLog.md): Thin wrapper around `PhoenixKit.Activity.log/3` for the OG plugin.
- [PhoenixKitOG.Assignments](PhoenixKitOG.Assignments.md): Context for binding templates to scopes inside a consumer module's
hierarchy.
- [PhoenixKitOG.Errors](PhoenixKitOG.Errors.md): Central mapping from error atoms (returned by `PhoenixKitOG.Templates`,
`PhoenixKitOG.Assignments`, and the render pipeline) to translated,
user-facing strings.
- [PhoenixKitOG.Gettext](PhoenixKitOG.Gettext.md): Gettext backend for OpenGraph-module-specific UI strings.
- [PhoenixKitOG.Migrations](PhoenixKitOG.Migrations.md): Module-owned versioned migrations for `phoenix_kit_og` — the
decentralized-migrations protocol that core's `mix phoenix_kit.update`
discovers via `migration_module/0`. This follows the canonical shape
documented in `phoenix_kit_hello_world`'s README ("Versioned migrations",
"Adopting a table core already creates") and its
`mix phoenix_kit_hello_world.audit_migrations` task: **two readers**
(`migrated_version/1` for migration context, `migrated_version_runtime/1`
for Mix-task context), `up/1` re-reading the version before it changes
anything, and a namespaced `COMMENT ON TABLE` marker on one anchor table.
`PhoenixKitPublishing.Migrations` is this chain's closest sibling in
spirit — same adoption situation, same semantic-guard requirement —
scaled down here to 2 tables, 1 FK, 1 named UNIQUE constraint and 3
indexes (all on the same table), and extended with a new invalid-index
self-heal no sibling chain in this workspace has needed yet.
- [PhoenixKitOG.Paths](PhoenixKitOG.Paths.md): Centralized path helpers — every link routes through
`PhoenixKit.Utils.Routes.path/1` so the configured admin prefix and
locale handling are honored.

- [PhoenixKitOG.Render](PhoenixKitOG.Render.md): Top-level rendering facade. Given a template + binding values,
produces a PNG (cached) and returns its public URL.
- [PhoenixKitOG.Render.Cache](PhoenixKitOG.Render.Cache.md): On-disk cache for rendered OG PNGs.
- [PhoenixKitOG.Render.Media](PhoenixKitOG.Render.Media.md): Media resolution + render-mode pre-processing between the stored scene
and `OpenFresco.render/3`.
- [PhoenixKitOG.Routes](PhoenixKitOG.Routes.md): Route registration for routes that can't be inlined on a `Tab` —
notably the per-template editor at `/admin/open-graph/:uuid/edit`.
- [PhoenixKitOG.SceneEdit](PhoenixKitOG.SceneEdit.md): Editor-side scene mutations the property panel drives — the
counterpart to `OpenFresco.Editor.Ops` (which owns pointer gestures:
move/resize/hit-test/front/delete). Everything here takes untrusted
form input, so every field goes through a whitelist + coercion; an
unknown field or junk value returns the scene unchanged.
- [PhoenixKitOG.SceneStore](PhoenixKitOG.SceneStore.md): Loads/saves `OpenFresco.Scene` documents from the template's `canvas`
JSONB column, with lazy migration from the legacy canvas format.
- [PhoenixKitOG.Schemas.Assignment](PhoenixKitOG.Schemas.Assignment.md): Binds a template to a scope inside a consumer module's hierarchy.
- [PhoenixKitOG.Schemas.Template](PhoenixKitOG.Schemas.Template.md): A reusable OpenGraph design — canvas + ordered elements with variable
bindings. Persisted as JSONB so the structure can evolve (new element
types) without a schema change.
- [PhoenixKitOG.Templates](PhoenixKitOG.Templates.md): Context for managing OpenGraph templates. CRUD only — the editor and
renderer live elsewhere.
- [PhoenixKitOG.Variables](PhoenixKitOG.Variables.md): Registry + resolver for module-exposed variables that templates can
bind their slots to.
- [PhoenixKitOG.Web.AssignmentsLive](PhoenixKitOG.Web.AssignmentsLive.md): Assignments admin — the overview of every template binding + a
single modal for creating **or** editing an assignment.
- [PhoenixKitOG.Web.EditorLive](PhoenixKitOG.Web.EditorLive.md): The OG template editor — OpenFresco's server-authoritative editor
stage on the left, this module's chrome around it: toolbar + insert
menu, slots panel, property panel, and the always-on preview pane.
- [PhoenixKitOG.Web.EditorLive.Template](PhoenixKitOG.Web.EditorLive.Template.md): HEEx render template for the OG editor. Split out from the LV module
so the event-handler code stays scannable.
- [PhoenixKitOG.Web.ImageController](PhoenixKitOG.Web.ImageController.md): Serves rendered OG PNGs from the on-disk cache.
- [PhoenixKitOG.Web.StagePlaceholder](PhoenixKitOG.Web.StagePlaceholder.md): The arrows stand-in image for the editor stage's sample-values mode —
a light-gray square with four arrows radiating to the corners and a
"Placeholder image" caption, shipped as a `data:image/svg+xml` URL.
- [PhoenixKitOG.Web.TemplatesLive](PhoenixKitOG.Web.TemplatesLive.md): Admin landing page for the OG module — lists templates and the
create/delete actions. The visual editor is Phase 2; this page only
carries minimal CRUD scaffolding so the module is interactive end-to-end.
