-- Adds embed + thread-context columns to `posts`.

--

-- Why
|

--
|
||||
-- Phase 4 (indexer) only stored `text` + `parent_uri` + `root_uri`, which
|
||||
-- was enough to render plain-text timelines. Phase 5 wants embeds (images,

--
|
||||
-- Columns
|

-- embed JSONB, nullable — the full AT-Protocol embed
|
||||
-- object as it appears in the record value. We
|
||||
-- store the whole thing verbatim rather than
|
||||
-- normalising into a separate `embeds` table so
|
||||
-- the UI can decode it without a second round
|
||||
-- trip, and so a future lexicon change doesn't
|
||||
-- require a schema migration.
|
||||
-- reply_parent_handle TEXT, nullable — display handle for
|
||||
-- `parent_uri`'s author. Backfilled by the
|
||||
-- handle-sync worker. Nullable because the
|
||||
-- sync worker hasn't seen the row yet, OR
|
||||
-- because the parent isn't in our index.
|
||||
-- reply_root_handle TEXT, nullable — display handle for
|
||||
-- `root_uri`'s author. Same semantics.
|
||||
-- reply_root_uri TEXT, nullable — duplicate of `root_uri`
|

-- for the "show full thread" link target.
|
||||
-- Kept as its own column so the index covers

-- the existing `root_uri`.
|

-- AppView migration 0004: like/repost counter cache + uniqueness
|
||||
--
|
||||
-- Phase 5b review identified two issues:
|
||||
-- H3 — Users could spam `feed.like.create` against the same post because
|
||||
-- the `likes` PK is just `uri` (the like's own rkey). Adding a
|
||||
-- partial unique index lets us short-circuit "already liked" at the
|
||||
-- DB layer instead of relying on caller discipline.
|
||||
-- H6 — `SELECT COUNT(*) FROM likes WHERE post_uri = $1` on every post fetch
|
||||
-- doesn't scale. We add a denormalized counter on `posts` that's
|
||||
-- kept consistent by the AppView's own ingest path. Jetstream-driven
|
||||
-- upserts touch this too. The PDS path goes through ingest-commit
|
||||
-- which routes through the same code.
|
||||
--
|
||||
-- Idempotent: dedup likes/reposts first (real-world Jetstream replays can
|
||||
-- leave duplicates). Keep only the oldest row per (did, post_uri).
