Greenfield SX-native pivot (NOT a strangler): the host speaks SX/SXTP end to end;
JSON only at the future ActivityPub federation edge.
- OUTPUT: host/json-status -> host/sx-status — every host/ok/host/error response is
text/sx via the serialize primitive (NOT application/json). Flips feed, relations,
blog reads. Tests assert the SX envelope ({:ok true :data ...}).
- DELETE the blog JSON CRUD /posts (POST/PUT/DELETE) + bearer-based host/blog--protect:
a pure old-contract REST mirror. Create/edit go through the HTML editor forms;
programmatic writes speak SXTP. FOLLOW-UP: no browser delete route yet (was JSON-only,
no UI) — add POST /:slug/delete + cascade edge cleanup when the metamodel UI needs it.
- INPUT: host/sx-body (sxtp.sx) parses a text/sx request body to a string-keyed dict
(parse-safe + sxtp/-normalize). feed POST + relations attach/detach read it.
- UNIFIED field reader host/fields / host/field: text/sx body OR urlencoded form by
content-type. The blog form handlers (new/edit/relate/unrelate) + login read through
it — additive, urlencoded still works (no-engine / bootstrap fallback).
Conformance 290/290 (11 suites). Retires the strangler framing in the plan; adds the
'SX all the way out' wire table. The engine half (browser posts text/sx) follows.

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.
