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/

# Upload embeds. `upload_id` points at a row in the `uploads` table. The importer
|
|
# reads that upload's `upload://...` markdown from the uploads store and puts it in
|
|
# the owner's markdown. `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.
|
|
#
|
|
# `original_markdown` is the verbatim source snippet for an upload referenced by a
|
|
# full URL (e.g. `/uploads/.../<sha1>.png`), nil for a short `upload://` reference.
|
|
# When the sha1 maps to no Discourse upload, the importer puts this snippet back
|
|
# unchanged instead of dropping the embed — a hotlink to another forum's upload then
|
|
# survives as-is.
|
|
#
|
|
# NOTE: `upload_id` is `:text`, not `:numeric`. Upload `original_id`s in the
|
|
# IntermediateDB are content hashes (see `uploads.id`, also `:text`). This matches
|
|
# the global `.*upload.*_id$ => :text` convention, so the reference must be text too.
|
|
# `original_markdown` is not an id, so the convention does not apply to it.
