+-- Fix pending_queue_actions schema mismatches
+--
+-- The original migration created id as UUID, but the enqueue edge function
+-- inserts a sha256 hex string (not a valid UUID), causing every enqueue call
+-- to return 500. subreddit_name and verdict_hash were also missing columns
+-- that the handler inserts, producing the same error.
+--
+-- The poller in extension-bridge.ts was also querying subreddit_id ILIKE
+-- subredditName, but the handler stores the t5_ Reddit ID in subreddit_id
+-- and the display name in subreddit_name, so the query never matched.
+-- That code fix is in collab-guard/src/server/core/extension-bridge.ts.
+
+-- 1. Change id from UUID to TEXT (handler inserts sha256 hex, not a UUID)
+ALTER TABLE public.pending_queue_actions ALTER COLUMN id TYPE TEXT USING id::TEXT;
+ALTER TABLE public.pending_queue_actions ALTER COLUMN id DROP DEFAULT;
+
+-- 2. Add subreddit_name (handler inserts body.subredditName here)
+ALTER TABLE public.pending_queue_actions ADD COLUMN IF NOT EXISTS subreddit_name TEXT;
+
+-- 3. Add verdict_hash (handler inserts body.verdictHash here)
+ALTER TABLE public.pending_queue_actions ADD COLUMN IF NOT EXISTS verdict_hash TEXT;
