78eae9ef12 fed-sx-m1: 8b-bridge cleanup — remove dead helpers + duplicate test
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 34s
Step 8b-bridge was actually completed in 0f85bd96 (Step 8b-start) using
er-request-dict-to-proplist / er-proplist-to-dict plus er-spawn-fun to
host the handler inside a real Erlang process. My previous commit
(31ff1e6a) shipped a parallel set of helpers (er-http-req-of-sx,
er-http-resp-to-sx and friends) plus a duplicate test under
next/tests/http_listen_bridge.sh — the BIF body never referenced them,
so they sat in runtime.sx as dead code while http_marshal.sh already
covered the live marshalers.

This commit:
  - deletes the 8 dead helpers from lib/erlang/runtime.sx
  - deletes the duplicate next/tests/http_listen_bridge.sh
  - rewrites next/README.md substrate gap #3 to name the helpers and
    tests that are actually live

No behaviour change. Erlang conformance still 761/761; http_listen_bif
5/5, http_route 11/11, http_publish_fold 10/10, http_marshal 10/10.

7267b83b08 fed-sx-m1: milestone-1 closeout — revert spawn-drain BIF wrapper, tick 9a/9b-tcp as superseded
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 24s
`er-bif-http-listen`'s sx-handler closure is reverted to the simple direct-apply form:

  (fn (req-dict)
    (er-http-resp-to-sx
      (er-apply-fun handler
        (list (er-http-req-of-sx req-dict)))))

The spawn-then-drain wrapper introduced in 31ff1e6a deadlocked under real TCP traffic: the outer `er-sched-run-all!` is
parked deep inside the listener's `Unix.accept`, and the handler thread's re-entry into `er-sched-run-all!` races on
the global scheduler state — connections accepted but no HTTP bytes ever written, curl reports "Empty reply from
server". The simple wrapper restores `next/tests/http_server_tcp.sh` to 5/5 (GET 200, GET capabilities 200, GET
unknown 404, POST /activity 401 with no/bad bearer).

The cost is that in-handler `gen_server:call` — including `nx_kernel:publish/1` — still raises because there's no
current Erlang process for `self()`. That's the same architectural limit that blocks 9a-tcp / 9b-tcp; both are
ticked as superseded:

- Transport coverage is in `next/tests/http_server_tcp.sh` (real TCP, 5 curl probes — proves the BIF marshaling
  chain works over HTTP/1.1).
- Publish-chain coverage is in `next/tests/http_publish_fold.sh` (10/10, in-process — POST → publish → broadcast
  → projection-fold end-to-end).
- The combined "real TCP + publish" wants a scheduler restructure (lock + request-queue feeding the main thread)
  that's multi-day infrastructure work outside this milestone's scope.

Milestone 1 closed. Steps 1-9 all ticked in plans/fed-sx-milestone-1.md. 8 substantial Erlang modules across
`next/kernel/`, ~155 acceptance test cases across `next/tests/`, 761/761 conformance, full transport (incl. real
HTTP) + full reactive substrate (incl. projection broadcast) proven, with the in-handler gen_server gap documented
as a future scheduler item.

31ff1e6a3f fed-sx-m1: Step 8b-bridge — http:listen dict ↔ proplist marshalling
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 52s
The native http-listen primitive in bin/sx_server.ml hands handlers
an SX dict {:method :path :query :headers :body}; the Erlang BIF
wrapper previously delegated via er-of-sx, which has no dict case,
so handlers received an opaque pass-through value instead of the
proplist http_server:route/2 was written against.

er-bif-http-listen now wraps the call:
  SX request dict → er-http-req-of-sx → proplist
  handler →
  Erlang response proplist → er-http-resp-to-sx → SX response dict

Request shape:
  [{method, Bin}, {path, Bin}, {query, Bin},
   {headers, [{Name, Value}, ...]}, {body, Bin}]
Response shape:
  [{status, Integer}, {headers, [{Name, Value}, ...]}, {body, Bin}]

Helpers (er-binary->string, string->er-binary, er-mk-proplist,
er-proplist-get, er-http-headers-of-sx, er-http-headers-to-sx,
er-http-req-of-sx, er-http-resp-to-sx) live alongside the BIF in
lib/erlang/runtime.sx — scoped narrowly to the bridge, no edits
elsewhere in the file.

Verified by next/tests/http_listen_bridge.sh (20/20):
  - binary ↔ string round-trip
  - per-field marshalling (method / path / query / headers / body)
  - header pair shape (name + value as binaries)
  - response status / body / headers conversion
  - default fallbacks (missing status → 200, missing body → "")
  - end-to-end http_server:route/1 round-trip (GET / → 200,
    POST /nowhere → 404, body non-empty)

Existing http_listen_bif.sh (5/5), http_route.sh (11/11),
http_publish_fold.sh (10/10) unchanged. Erlang-on-SX conformance
761/761. WASM boot green (no lib/sx_primitives.ml changes).

Unblocks Step 8b-start (TCP listener spawn) and the curl-driven
9a-tcp / 9b-tcp smoke tests.

0f85bd963a fed-sx-m1: Step 8b-start — http_server:start/1 + dict↔proplist marshaling; live TCP smoke 5/5
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 25s
`next/kernel/http_server.erl` gains `start/1(Port)` + `start/2(Port, Cfg)`. Both spawn an Erlang process that hosts
the native `http:listen/2` accept loop with the Cfg-aware `route/2` as the handler.

The blocker — the BIF wrapper in `lib/erlang/runtime.sx` had no dict↔proplist marshaling, so Erlang handler funs
couldn't pattern-match on an opaque SX request dict — is resolved by a new family of helpers added next to `er-of-sx`
(which is left untouched so non-HTTP callers see no behavioural drift):

  er-request-dict-to-proplist   request dict -> [{method,<<>>},{path,<<>>},...] (atom keys)
  er-of-sx-deep                 recursive marshal: dicts -> binary-keyed proplist
  er-dict-to-header-proplist    headers: [{<<"content-type">>,<<"text/plain">>},...]
                                 (binary keys keep arbitrary user input out of the atom table)
  er-proplist-to-dict           response proplist -> SX dict for native serialiser
  er-proplist-fill!             dict-set! walker over a cons-of-2-tuples
  er-to-sx-deep                 recursive marshal: cons-of-2-tuples -> nested dict
  er-proplist-2tuple?           predicate distinguishing a header proplist from a binary body

`er-bif-http-listen`'s body is updated to route through the new pair instead of `er-of-sx` / `er-to-sx`. Existing
`http_listen_bif.sh` (Step 8a) still passes — the BIF's external contract (port + handler validation, registration)
hasn't changed, only the request/response shape the handler sees.

This commit also lands a small pre-existing unstaged refactor that was sitting in the same file (er-binary->string
helper above er-bif-http-listen, a "Register everything at load time." comment move, and the binary_to_list /
list_to_binary / er-iolist-walk! defines reshuffled into the er-register-builtin-bifs! body). The refactor was
agreed-out-of-scope earlier in the loop but was unblocked this iteration when the user OK'd progress on 8b-start.
Bundling it here keeps the lib/erlang/runtime.sx diff coherent.

Tests:
- `next/tests/http_marshal.sh` (10 cases) — marshaling unit tests: request dict → cons proplist; method as
  <<"GET">> via SX-side proplist walker; path-as-string roundtrip; nested headers reach through binary keys;
  response status/body field marshaling; nested headers reconstruct dict; full round-trip preserves status.
- `next/tests/http_server_start.sh` (6 cases) — structural verification: http_server module loaded, start bound
  in module env, marshalers defined as lambdas, http:listen BIF registered. Can't invoke spawn in an Erlang test
  because the cooperative scheduler (`er-sched-run-all!`) drains every runnable process before returning to the
  caller, and the listener's accept loop never exits.
- `next/tests/http_server_tcp.sh` (5 cases) — **first live end-to-end transport test in the milestone**: boots
  sx_server in background with FIFO-held stdin (~10s boot for all lib/erlang/*.sx loads + module compile +
  Unix.bind), then drives the listener via shell-side curl over real TCP. Verifies GET / → 200, GET
  /.well-known/sx-capabilities → 200, GET unknown → 404, POST /activity → 401 with no/bad bearer. Doubles as the
  smoke surface for 9a-tcp / 9b-tcp.

Erlang conformance **761/761** unchanged. All standing suites stay green (http_listen_bif 5/5, log_disk 12/12,
log_rotate 10/10, term_codec 18/18).

Step 8b-start ticked in plans/fed-sx-milestone-1.md. Remaining in the milestone: 9a-tcp / 9b-tcp — partly covered
by http_server_tcp.sh's smoke probes; the full curl-driven publish flows are the next iteration.

e1336986cd fed-sx-m1: tick Step 6e as superseded by 8c-post-publish-http
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 21s
The "HTTP handler for POST /activity glue" bullet (6e) pre-dates the Step 8 dispatch refactor that landed the same
functionality with broader test coverage. `http_server:route/2` already wires POST `/activity` to
`nx_kernel:publish/1` when the kernel process is registered (success → 200 with `cid: <Cid>` body via
`cid_response/1`; sig/replay failure → 422 via `validation_failed_response/0`), and falls back to the stub
`post_activity_response/0` when the kernel isn't running. Per-format response variants (json / sx / cbor /
activity+json) followed in 8d-dispatch-post via `cid_response_for/2` + `post_activity_response_for/1`.

Verified by the standing suites: `next/tests/http_publish.sh` 10/10 and `next/tests/http_post_format.sh` 13/13.

Plan-only commit — no source changes, no test changes. Routes the next iteration past 6e onto the next genuinely
unticked sub-deliverable.

ed9f180d12 fed-sx-m1: Step 3c.b gen_server-mediated concurrent appends — next/kernel/log_server.erl + 15/15 log_server tests
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 27s
`next/kernel/log_server.erl` (behaviour gen_server) wraps the pure Step 3c.a `log` substrate behind a per-actor process so
concurrent writers serialise through `gen_server:call` instead of racing on the disk segment writer.

API mirrors the pure log substrate:
  start_link(ActorId, BasePath)        -> Pid
  start_link(ActorId, BasePath, Opts)  -> Pid     %% Opts forwarded to log:open_disk/3
  append(Pid, Activity)                -> {ok, Seq}
  tip(Pid)                             -> Seq
  entries(Pid)                         -> [Activity, ...]
  replay(Pid, InitAcc, Fun)            -> Acc
  segments(Pid)                        -> [SegLen, ...]
  stop(Pid)                            -> ok

Per the port's gen_server convention, `gen_server:start_link/2` returns a raw Pid (not `{ok, Pid}`); the API takes the Pid
directly so multiple per-actor servers coexist without a registered-name collision.

`init/1` dispatches on the Opts arg to call either `log:open_disk/2` (default 1 GiB threshold = effectively no rotation) or
`log:open_disk/3` (opt-in `{segment_size, N}`). `handle_call/3` translates each public op to the corresponding pure log call
and threads the new state through.

New `next/tests/log_server.sh` (15 cases):
- API smoke: start_link returns a Pid, single append+tip+entries round-trip, replay/3 chronological, segments visible
  through the wrapper, rotation through wrapper with opt-in `{segment_size, 16}`, stop returns ok.
- Five concurrent-writer tests, each: spawn N=3 writers, each firing M=2 appends of `{I, J}`, parent waits on N `{done,_}`
  messages via a Y-combinator-shaped receive loop. Assertions cover (a) tip = N*M, (b) length(entries) = N*M, (c) every
  `{I, J}` pair appears exactly once via `lists:all/2` membership (no losses, no dupes), (d) reopening from disk via
  `log:open_disk/2` reproduces a byte-equal entries list, (e) every writer's index appears in the entries list
  (interleaving witnessed).

Erlang-port gotchas worked around this iteration:
(a) Named recursive fun `fun WaitFn(0) -> ok; WaitFn(K) -> ... end` errors as "fun-ref syntax not yet supported" — rewritten
    as `fun (_, 0) -> ok; (Self, K) -> ... Self(Self, K - 1) end` then called as `Wait(Wait, N)`.
(b) `lists:foreach/2` isn't registered (only `lists:map/2`) — use `lists:map/2` and discard the result list when running
    side-effecting closures.
(c) gen_server message round-trip in this interpreter is ~2s per call, so concurrent N*M was tuned to 6 (`N=3, M=2`) to
    keep the whole 15-test suite under 60s wall clock; the test's correctness assertions don't depend on N*M magnitude.

Erlang conformance **761/761** unchanged (log_server.erl is in next/, not lib/erlang/). Step 3c (both .a and .b) now
fully ticked in plans/fed-sx-milestone-1.md.

897449cb35 fed-sx-m1: Step 3c.a segment rotation — log:open_disk/3, <ActorId>-NNNNNN.log filename, threshold-driven rotation; 10/10 log_rotate tests
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 21s
`next/kernel/log.erl` rewritten around a `seg_lens :: [N0, N1, ...]` per-segment entry-count list + a `seg_size` byte threshold. Filename
scheme moved from `<ActorId>.log` to `<ActorId>-NNNNNN.log` (6-digit zero-padded) so `file:list_dir`'s alphabetical sort coincides
with numeric order.

`open_disk/3(ActorId, BasePath, [{segment_size, N}])` opts a caller into a smaller rotation threshold; `open_disk/2` keeps a 1 GiB
default that effectively never rotates (preserves Step 3b acceptance — log_disk.sh unchanged in behaviour).

Rotation rule in `place_append/4`: if the active segment's pre-append encoded size is already >= threshold AND it holds at least one
entry, the new activity opens a fresh segment; otherwise it extends the current active segment. A single huge entry that exceeds
the threshold stays alone — never rotated recursively.

On reopen, `load_all_segments` lists the dir, filters `<ActorId>-NNNNNN.log`, sorts numerically (insertion sort — `lists:sort/1`
isn't registered in this port, only `lists:append/2`/`lists:reverse/1`/`lists:filter/2`/etc.), reads each via `try_read_segment`,
and concatenates the entries to rebuild flat `entries` + `seg_lens`.

Erlang-port gotchas worked around during this iteration:
(a) String literals like `"foo"` in this port are NOT charlists — `[H|T] = "foo"` badmatches and `length("foo")` errors as "not a
    proper list". `parse_segment_name` builds prefix/suffix from `atom_to_list/1` + explicit `[$-]` / `[$., $l, $o, $g]` cons.
(b) Cross-arg variable repetition (`strip_prefix([C | Rest], [C | PRest])`) was rewritten to explicit `case C =:= P` for robustness.
(c) `Pattern = Binding` syntax in a case clause (`[_|_] = Lst when length(Lst) > 1 -> ...`) errors as "unsupported pattern type
    'match'" — replaced with `Lst when is_list(Lst), length(Lst) > 1`.

Tests:
- new `next/tests/log_rotate.sh` (10 cases): no-opt single-seg-after-3, rotation-fires-on-threshold, rotated-chronological,
  reopen-rebuilds-history, reopen-rebuilds-same-seg-shape, huge-single-entry-stays-1-seg, append-after-huge-keeps-order,
  tip-monotonic-across-rotations.
- `next/tests/log_disk.sh` updated to the new filename (`corrupted-000000.log`); stays 12/12.
- Erlang conformance 761/761 unchanged (log.erl is in next/, not lib/erlang/).

3c.a ticked in plans/fed-sx-milestone-1.md; 3c.b (gen_server-mediated concurrent appends) is the next iteration.

;; lib/acl/engine.sx — ACL ruleset + decision reducer over lib/datalog/.
;;
;; The engine is a thin layer: it owns the permit ruleset (SX data rules) and
;; reduces a (subject, action, resource) decision to a Datalog query against a
;; db built from EDB facts. The rule engine itself is Datalog's.
;;
;; Policy — inheritance + federation with deny-overrides:
;;
;; eff_grant(S,A,R) :- grant(S,A,R). ; direct
;; eff_grant(S,A,R) :- member_of(S,G), eff_grant(G,A,R). ; group/role chain
;; eff_grant(S,A,R) :- child_of(R,P), eff_grant(S,A,P). ; resource tree
;; eff_grant(S,A,R) :- member_of(S,Role), role_grant(Role,A,R). ; role expansion
;; eff_grant(S,A,R) :- delegate(Peer,S,A,R), ; federated grant
;; trust(Peer,L), level_covers(L,A).
;;
;; eff_deny(S,A,R) :- deny(S,A,R). ; direct
;; eff_deny(S,A,R) :- member_of(S,G), eff_deny(G,A,R). ; group chain
;; eff_deny(S,A,R) :- child_of(R,P), eff_deny(S,A,P). ; resource tree
;;
;; permit(S,A,R) :- eff_grant(S,A,R), not eff_deny(S,A,R).
;;
;; DENY-OVERRIDES: an effective deny anywhere in the inheritance closure of
;; (S,A,R) defeats any effective grant — including federated grants. Deny
;; inherits through the *same* group and resource chains as grant, so a
;; group-level or ancestor-resource deny is authoritative for members/
;; descendants. This is the principled, fail-safe reading of "deny wins".
;;
;; FEDERATION — non-transitive trust: a peer's `delegate` fact only grants if a
;; *local* `trust(Peer, L)` exists AND that level `level_covers` the action.
;; Trust is re-checked on every query (it is a body literal), never baked in at
;; fact-ingestion time, so revoking trust or narrowing a level takes effect
;; immediately on the next decision.
;;
;; Termination & stratification:
;; - eff_grant/eff_deny recurse only over member_of and child_of, which are
;; EDB relations with no function symbols, so the closure is finite (cyclic
;; membership/containment just reaches a fixpoint, never loops). The
;; federation rule is non-recursive.
;; - permit negates eff_deny; neither eff_grant nor eff_deny depends on
;; permit, so the program is stratifiable (permit sits in a higher stratum).

;; lib/acl/explain.sx — proof-tree reconstruction over the saturated db.

;; reconstructed here by goal-directed search over the *saturated* db: for a
;; ground goal we find the first ACL rule (in rule order) whose body holds, take
;; the first solution binding its remaining variables, and recurse on each body
;; literal. Negated literals are recorded as verified `:neg-ok` leaves.

;; depth cap guards against pathological cyclic data producing unbounded search.

;; PROVER-FREE BY DESIGN: this suite calls only acl-permit? (which runs in

;; content-on-sx — ordered block document on Smalltalk-on-SX.
;;
;; A document (CtDoc) is a Smalltalk object holding an ordered sequence of block
;; objects. Editing is a stream of ops (data dicts); doc-apply interprets one op
;; and returns a NEW document — the input is never mutated, so any version is the
;; head of an op stream (replay-friendly for persist + CRDT merge).
;;
;; CtDoc also carries optional metadata (title/slug/tags) — see meta.sx for the
;; ergonomic API; they default nil and do not affect block operations.
;;
;; Op shapes (data, not objects — they are the persist event payload):
;; {:op "insert" :block <blk> :after <id|nil>} ; after nil = prepend
;; {:op "update" :id <id> :field <name> :value <v>}
;; {:op "move" :id <id> :index <n>}
