Migrate the container relations write actions onto lib/relations: POST
/internal/actions/attach-child + /detach-child dispatch to relations/relate
and relations/unrelate over the same "type:id" node model, behind the
auth+ACL pipeline (wrap-errors . require-auth . require-permission), mirroring
POST /feed. Closed-loop test: attach -> visible via get-children -> detach ->
gone; 401/403/400 guards. Ledger now models the full relations surface (7
endpoints): container reads+writes migrated, typed relate/unrelate/can-relate
proxied (registry+cardinality validation not in lib/relations). Off-Quart
coverage 45% -> 50%.

Migrate the two internal relations read queries onto lib/relations: GET
/internal/data/get-children + /get-parents dispatch to relations/children
and relations/parents. Bridge the Quart (type,id) node key to a graph atom
symbol "type:id" with relation-type as the edge kind; optional child/parent
-type params filter by "type:" prefix. Golden tests pin each endpoint to
subsystem-call + envelope. Ledger entries flipped to :migrated (off-Quart
coverage 27% -> 45%).

lib/host/sxtp.sx implements the host<->subsystem wire format per
applications/sxtp/spec.sx:
- message algebra (request/response/condition/event + status helpers
ok/created/not-found/forbidden/invalid/fail) as string-keyed dicts;
verb/status/type stored as symbols (ride the wire bare)
- codec: sxtp/serialize (dict -> text/sx list form, deterministic top-level
field order, nested messages emitted in their own list form, no :msg leak)
and sxtp/parse (text/sx -> dict via a deep keyword-token->string normaliser)
- Dream bridge: sxtp/from-dream (HTTP req -> SXTP req, method->verb,
query->params) and sxtp/to-dream (SXTP resp -> HTTP resp, status->code,
body serialised to text/sx)
- 39-test suite covering algebra, serialise/parse round-trip, mappings, bridge
Runtime notes: serialize renders string-keyed dicts as {:k v} and symbols
bare; parsed keyword tokens are a distinct type (not = to string literals) so
parse normalises; unquote-splicing is unreliable so the emitter is str-based.

Composable handler->handler layers over Dream's primitives, with auth and
permission POLICY injected so the layer is policy-free and testable:
- middleware.sx: host/wrap-errors (JSON 500 via dream-catch-with),
host/require-auth (bearer->principal via dream-bearer-token, JSON 401,
injected token resolver), host/require-permission (lib/acl acl/permit? gate,
JSON 403, injected resource extractor), host/pipeline (first = outermost)
- feed.sx: POST /feed via host/feed-write-routes — auth ∘ ACL(post,feed) ∘
wrap-errors over host/feed-create (parse JSON body -> feed/post -> 201;
non-object -> 400). Created activity reads back via GET /feed.
- middleware suite (9) + feed write tests (6 new); conformance preloads now
include the Datalog engine + ACL subsystem + Dream auth/error.
ACL works with string atoms (no symbol coercion). Mute/prefs layer and sxtp.sx
deferred to the next tick.

First migrated endpoint onto the SX host. lib/host is a thin wiring layer:
a host handler is a Dream handler (request->response) that calls a subsystem
public API and serialises via a shared JSON envelope.
- handler.sx: host/ok, host/ok-status, host/error, host/json-status (Dream's
dream-json is 200-only), host/query-int
- router.sx: host/make-app assembles per-domain route groups + /health probe
into one dream-router (reuses dr/flatten-routes)
- feed.sx: GET /feed reads feed/all + stream combinators, recent-first, with
?actor= filter and ?limit= cap
- 3 test suites incl. a golden test (body == subsystem recent stream + envelope)
- conformance.sh mirrors lib/dream's runner
Builds on dream-on-sx (merged, gate green 480/480) rather than a throwaway
native request model; collapses most of plan Phase 4 into Phase 1.
