The post_* linkage tables from #41177 become embed_* tables keyed by (owner_type, owner_id), because placeholders will also live in user bios and group/category/badge descriptions later. On top of the rename: - quotes carry source coordinates (topic id + post number) and links a typed target, so the importer can resolve both once the id maps exist - new hashtag and emoji linkage tables; mention_type, hashtag_type and link_target become integer enums and the string MentionType is gone - EmbedBuffer records for one owner kind, PlaceholderResolver resolves and renders per owner and reports unresolved embeds and orphaned placeholders - the posts and custom_emojis tables stay ignored until their conversion steps land in a follow-up PR - the lazy source-name lookups (users, groups, categories with their slug paths, synonym-folded tags) live in their own NameResolver, and the resolver spec is split by phase under placeholder_resolver/

# `[quote]` embeds. These point at no Discourse entity; they are just text the
|
|
# importer rewrites once the `original_id -> discourse_id` maps exist. `placeholder`
|
|
# holds the token spliced into the owner's markdown (a post body today, a user bio
|
|
# etc. later); see `Migrations::Placeholder`. `owner_type`/`owner_id` name that
|
|
# owning record. `quoted_username` and `quoted_name` are the source's fallback
|
|
# display, used when the quoted user can't be mapped to a Discourse user. The
|
|
# username doubles as the lookup key: when `quoted_user_id` is nil, the importer
|
|
# resolves it to the user's `original_id` (in memory, never written back).
|
|
#
|
|
# The quoted post is identified either by its source `original_id` (`quoted_post_id`,
|
|
# filled by converters that know it) or by the source coordinates the attribution
|
|
# carries (`quoted_topic_id` + `quoted_post_number`, the source's own numbering).
|
|
# The importer resolves the coordinates to a `quoted_post_id` before rendering.
