d12f38a9d5 sx-pub Phase 4: anchoring — Merkle trees, OpenTimestamps, verification 
New endpoints:
- POST /pub/anchor — batch unanchored Publish activities into Merkle tree,
  pin tree to IPFS, submit root to OpenTimestamps, store OTS proof on IPFS
- GET /pub/verify/<cid> — verify a CID's Merkle proof against anchored tree

Uses existing shared/utils/anchoring.py infrastructure:
- build_merkle_tree (SHA256, deterministic sort)
- get_merkle_proof / verify_merkle_proof (inclusion proofs)
- submit_to_opentimestamps (3 calendar servers with fallback)

Tested: anchored 1 activity, Merkle tree + OTS proof pinned to IPFS,
verification returns :verified true with full proof chain.

aa1d4d7a67 sx-pub Phase 3: federation — outbox, inbox, follow, delivery, HTTP signatures 
New endpoints:
- GET /pub/outbox — paginated activity feed
- POST /pub/inbox — receive Follow/Accept/Publish from remote servers
- POST /pub/follow — follow a remote sx-pub server
- GET /pub/followers — list accepted followers
- GET /pub/following — list who we follow

Federation mechanics:
- HTTP Signature generation (RSA-SHA256) for signed outgoing requests
- HTTP Signature verification for incoming requests
- Auto-accept Follow → store follower → send Accept back
- Accept handling → update following state
- Publish mirroring → pin remote CID to local IPFS
- deliver_to_followers → fan out signed activities to all follower inboxes
- Publish now records activity in outbox for federation delivery

cf130c4174 sx-pub Phase 2: publish to IPFS, browse collections, resolve by path + CID 
New endpoints:
- POST /pub/publish — pin SX content to IPFS, store path→CID in DB
- GET /pub/browse/<collection> — list published documents
- GET /pub/doc/<collection>/<slug> — resolve path to CID, fetch from IPFS
- GET /pub/cid/<cid> — direct CID fetch (immutable, cache forever)

New helpers: pub-publish, pub-collection-items, pub-resolve-document, pub-fetch-cid

Tested: published stdlib.sx (6.9KB) → QmQQyR3Ltqi5sFiwZh5dutPbAM4QsEBnw419RyNnTj4fFM

7b3d763291 sx-pub Phase 1: DB schema, IPFS wiring, actor + webfinger + collections + status endpoints 
Foundation for the sx-pub federated publishing protocol:

- 6 SQLAlchemy models: actor, collections, documents, activities, followers, following
- Conditional DB enablement in sx_docs (DATABASE_URL present → enable DB)
- Python IO helpers: get_or_create_actor (auto-generates RSA keypair),
  list_collections, check_status, seed_default_collections
- 4 defhandler endpoints returning text/sx (no JSON):
  /pub/actor, /pub/webfinger, /pub/collections, /pub/status
- Alembic migration infrastructure for sx service
- Docker compose: DB + pgbouncer + IPFS + env vars
