+## [0.5.3] - 2026-08-26
+
+### Fixed
+- `Modules\Core\Search\ProductIndexer::toSearchableArray()` threw `column reference "id" is ambiguous` on Postgres when computing `channel_ids` — `$model->channels()->wherePivot('enabled', true)->pluck('id')` joins `lunar_channels` and `lunar_channelables`, both of which have an `id` column, and the unqualified `pluck('id')` left Postgres unable to resolve which table's column to select (SQLite/MySQL tolerated the ambiguity). Qualified as `pluck('lunar_channels.id')`.
