128 - [ ] Manage Repo Root in `repos` table.
129 - [ ] Implement Atomic Repo Transactions.
130 - [ ] Ensure `blocks` write, `repo_root` update, `records` index update, and `sequencer` event are committed in a single transaction.
131 - [ ] Implement concurrency control (row-level locking on `repos` table) to prevent concurrent writes to the same repo.
132- [ ] DID Cache

134 - [ ] Handle cache invalidation/expiry.
135- [ ] Background Jobs
136 - [ ] Implement background queue for async tasks (crawler notifications, discord/telegram 2FA sending instead of email).
137 - [ ] Implement `Crawlers` service (debounce notifications to relays).
138- [ ] Mailer equivalent
139 - [ ] Implement code/notification sending service as a replacement for the mailer because there's no way I'm starting with email. :D

142- [ ] IPLD & MST
143 - [ ] Implement Merkle Search Tree logic for repo signing.
144 - [ ] Implement CAR (Content Addressable Archive) encoding/decoding.
145- [ ] Validation
146 - [ ] DID PLC Operations (Sign rotation keys).
