fed-sx-m1: 8b-bridge cleanup — remove dead helpers + duplicate test

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.

-;; The engine is a thin layer: it owns the permit ruleset (SX data rules) and

-;; 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).

-;;
-;;   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/tests/harden.sx — adversarial / cross-phase hardening.
-;;
-;; Diamond hierarchies, conflict resolution where deny must win through every
-;; path, chain inheritance, cycle termination, multi-peer delegation, fact
-;; validation, and audit save/restore.
-;;
-;; PROVER-FREE BY DESIGN: this suite calls only acl-permit? (which runs in
-;; compiled Datalog, safe at any depth) plus pure data ops — never acl-explain /
-;; acl-prove-d. The SX-side proof reconstructor recurses, and once the kernel
-;; JIT-compiles it (after the explain/fed suites warm the process) it loops on
-;; chains deeper than ~3 (substrate JIT bug — see plan Blockers). Proof
-;; reconstruction is covered by tests/explain.sx (and federated proofs by
-;; tests/fed.sx), both of which stay under the warm-process depth threshold.

-# flow — durable DAG workflows on Scheme
-
-`flow` is a workflow engine for rose-ash: content pipelines (write → review →
-publish → federate), scheduled jobs, and multi-step user flows (signup, confirm,
-onboard) that **survive process restarts**. It is a thin Scheme prelude over the
-Scheme-on-SX guest (`lib/scheme/`); a flow runs *inside* the interpreter.
-
-Run the suite: `bash lib/flow/conformance.sh` → **151/151 across 10 suites**.
-
-## Model
-
-A **flow** is just a Scheme procedure of one argument — the upstream value:
-
-```
-node : input -> output
-```
-
-Combinators build composite nodes out of child nodes. A node that ignores its
-argument is effectively a thunk. There is no separate "graph" object: composition
-*is* function composition, so flows are values you can name, pass, and nest.
-
-```scheme
-(defflow publish
-  (sequence
-    (lambda (draft) (string-append draft "!"))
-    (branch (lambda (post) (>= (string-length post) 3))
-            (remote-node 'fed 'publish)
-            (flow-const 'rejected))))
-
-(flow/start publish "hello")   ; => federated, or a (flow-suspended id tag) state
-```
-
-## Building blocks (`spec.sx`)
-
-| Combinator | Meaning |
-|---|---|
-| `(flow-node f)` / `(flow-id x)` / `(flow-const v)` | leaf nodes |
-| `(sequence n ...)` | thread input left-to-right |
-| `(parallel n ...)` | fan input to every child, join results into a list (sequential eval) |
-| `(map-flow node)` | run `node` over each item of a list input, join results |
-| `(flow-while pred body max)` / `(flow-until ...)` | bounded iteration (cap `max` steps) |
-| `(defflow name body)` | bind + register a named flow (so it survives restart) |
-
-## Control flow + errors (`spec.sx`)
-
-| Combinator | Meaning |
-|---|---|
-| `(branch pred then else)` | `pred` on input selects `then`/`else` (`cond` is a Scheme special form) |
-| `(retry n node)` | re-run on a *raised exception*, up to `n` attempts |
-| `(timeout budget node)` | cooperative **step budget**: nodes call `(tick)`; the `(budget+1)`-th tick raises `flow-timeout` |
-| `(try-catch node handler)` | catch a raised exception → `(handler error)` |
-| `(fail reason)` / `(failed? x)` / `(fail-reason x)` | explicit failure *values* (flow downstream as data) |
-| `(recover node handler)` | the fail-VALUE counterpart of try-catch |
-| `(attempt n ...)` | railway sequence: stop at the first node returning a `(fail ...)` |
-| `(tap effect)` | run a side effect, return input unchanged |
-
-**Two error channels, on purpose.** Raised exceptions are for *bugs/transients*
-(caught by `retry`/`try-catch`). `(fail reason)` values are for *expected business
-outcomes* (validation rejected, declined) and compose via `attempt`/`recover`.
-
-## Suspend / resume — the durable core (`spec.sx`, `store.sx`)
-
-The guest Scheme's `call/cc` is **escape-only** — re-invoking a captured
-continuation after it returns *hangs* the runtime. So flow does **not** serialize
-continuations. Instead it uses **deterministic replay**:
-
-- `(suspend tag)` — if `tag` is already in the replay log, return its logged value;
-  otherwise escape to the driver as `(flow-suspended tag)`.
-- `resume` appends `(tag value)` to the log and **re-runs the flow from the start**.
-  Already-resolved suspends replay their values; the first unresolved one escapes
-  again (or the flow completes).
-
-The entire persisted state is the replay log — plain data. No live continuation is
-ever stored, so flows survive process restarts and even moves between instances.
-
-> **Author contract:** suspend `tag`s must be unique and deterministic across
-> replays, and **all** non-determinism / side effects must go through suspend
-> points (so their results are logged) — otherwise they re-run on every replay.
-
-### Lifecycle (`store.sx`)
-
-```scheme
-(flow/start flow input)   ; raw result if it completes, else (flow-suspended id tag)
-(flow/resume id value)    ; inject value at the waiting tag, continue
-(flow/cancel id)          ; terminate; a later resume is rejected
-```
-
-### Introspection & hygiene
-
-```scheme
-(flow/status id)   ; done | suspended | cancelled | unknown
-(flow/result id)   ; result if done, else (flow-error reason)
-(flow/list)        ; ((id status) ...)
-(flow/pending)     ; ((id waiting-tag) ...) — what each suspended flow awaits
-(flow/gc)          ; drop terminal records, keep live ones; returns count removed
-(flow/forget id)   ; drop one terminal record (refuses live flows)
-```
-
-### Crash recovery
-
-```scheme
-(flow-store-export)      ; the store as plain data (live procs nulled)
-(flow-store-import! d)   ; restore the store from exported data
-(flow-resumable-ids)     ; ids of suspended flows to wake on restart
-```
-
-On restart the flow definitions are reloaded (`defflow` re-registers names) and the
-exported store reimported; `resume` re-resolves each flow's procedure **by name**.
-
-## Distribution via fed-sx (`remote.sx`)
-
-```scheme
-(flow-peer-register! addr table)      ; mock a peer's exposed functions (fed-sx boundary)
-(remote-node addr fn)                 ; run a node on a peer
-(remote-failover addrs fn local)      ; try peers in order, fall through to a local node
-(flow-replicate-to addr)              ; copy this store to a peer's replica slot
-(flow-restore-from addr)              ; import a peer's replica (handoff)
-```
-
-**Handoff** is crash recovery across instances: replicate → local instance dies →
-peer restores the (plain-data) store and resumes. The replay log carries over, so
-all resolved suspends survive the move.
-

-
-## Notes on the substrate
-
-The guest Scheme (`lib/scheme/`, imported read-only) lacks dotted-rest params
-`(a . rest)` and named `let`; combinators use `(lambda args ...)` variadics + top-
-level recursion. `cons` is list-only (no dotted pairs), so log/assoc entries are
-2-element lists. Strings box as `{:scm-string "..."}`. Timeout is a step budget
-because there is no wall clock; `parallel` is sequential for the same reason.

-;;
-;; `suspend` is flow's seam to the outside world, but a bare (suspend tag) is just a
-;; signal — every author would invent their own tag shape. This layer defines a
-;; stable request/response contract so a host (e.g. an art-dag driver, or a human
-;; review UI) can hook in WITHOUT reverse-engineering ad-hoc tags.
-;;
-;; A flow asks the host to do something and waits for the answer:
-;;   (request kind payload)  — suspend with a typed envelope (flow-request kind
-;;     payload); evaluates to the host's resume value.
-;;   (await-human prompt)    — request kind=human (a decision point)
-;;   (await-render recipe)   — request kind=render (e.g. an art-dag job)
-;;   (await-effect kind p)   — request of an arbitrary kind
-;;
-;; The host drives flows by polling its work queue and resuming:
-;;   (flow-host-requests)    — ((id kind payload) ...) for every SUSPENDED flow whose
-;;     waiting tag is a host request. The host dispatches by kind (render -> submit a
-;;     Celery job; human -> show UI), then calls (flow/resume id answer).
-;;   (request? tag) / (request-kind tag) / (request-payload tag) — parse one tag.
-;;
-;; Reference driver — the host only supplies `dispatch`, a (kind payload) -> answer:
-;;   (flow-drive-host dispatch)        — one tick: service every CURRENTLY pending
-;;     request (snapshot), resuming each with (dispatch kind payload); returns the
-;;     count serviced. Resumes may create new requests — serviced on the next tick.
-;;   (flow-run-host dispatch maxticks) — tick until quiescent (no pending requests)
-;;     or maxticks reached; returns total requests serviced. Bounded for determinism.

-;;
-;;   (flow-peer-register! addr table) — register a mock peer. table is a list of

-;;     (flow-remote-unreachable) if the addr is unknown, (flow-remote-no-fn) if the
-;;     peer does not expose fn.
-;;   (remote-node addr fn)            — a node that runs fn on the peer at addr.

-;;     raised error move to the next peer; if every peer fails, run the `local`

-;;
-;; Persistence across instances + handoff. Each instance runs the same flow

-## Architecture
-
-Flow combinators are a **Scheme prelude** (`lib/flow/spec.sx`) loaded onto
-`scheme-standard-env`. A flow is a Scheme procedure `input -> output`. The whole
-flow executes inside the Scheme interpreter, so Phase 3's `suspend` (call/cc) will
-capture the flow continuation directly.
-
-- `lib/flow/spec.sx` — combinators: `flow-node`, `flow-id`, `flow-const`,
-  `sequence`, `parallel`, `defflow`; `flow-load-combinators!`.
-- `lib/flow/api.sx` — `flow/start` (Scheme); `flow-make-env`, `flow-run`,
-  `flow-run-in` (SX helpers).
-- `lib/flow/tests/basic.sx` — 18 cases.
-- `lib/flow/conformance.sh` — loads substrate + flow layer, runs suites.
-
-## Semantics notes
-
-- **node** = 1-arg Scheme procedure; the upstream value is the argument. A node
-  ignoring its argument is effectively a thunk.
-- **sequence** threads left-to-right; empty sequence = identity.
-- **parallel** fans the same input to every branch and joins results into a list.
-  Evaluation is **sequential** for now; true concurrency arrives in Phase 3.
-
-## Phases
-
-- [x] Phase 1 — Declarative DAG + sequential execution (combinators + 18 tests, `flow/start`)
-- [x] Phase 2 — Control flow + error handling (branch, error model, try-catch, retry, timeout)
-- [x] Phase 3 — Suspend/resume (suspend/resume/cancel + crash recovery via deterministic replay)
-- [x] Phase 4 — Distributed nodes via fed-sx (remote-node, failover, replication + handoff)
-- [x] Phase 5 — Operational API + combinators (introspection, tap, recover, map-flow)
-- [ ] Phase 3 — Suspend / resume (the showcase)
-- [ ] Phase 4 — Distributed nodes via fed-sx

-;; lib/flow/spec.sx — flow combinators as a Scheme prelude.
-;;
-;; A flow is a Scheme procedure of one argument: the upstream value.
-;;   node : input -> output
-;; A leaf node ignoring its argument is effectively a thunk. Combinators
-;; build composite nodes out of child nodes. The whole flow runs INSIDE the
-;; Scheme interpreter.
-;;
-;; Phase 1 combinators (flow-combinators-src):
-;;   flow-node / flow-id / flow-const / sequence / parallel / defflow
-;;   defflow both binds the flow and registers it by name (flow-register!, in
-;;   store.sx) so it can be re-resolved after a process restart.
-;;   map-flow (Phase 5): run a node over each item of a list input, join results.
-;;   flow-while / flow-until (Phase 5): bounded iteration — re-run body, threading
-;;   the value, while/until pred holds, up to `max` steps (deterministic bound; no
-;;   unbounded loops in pure SX).
-;;
-;; Phase 2 combinators (flow-control-src):
-;;   branch / fail / failed? / fail-reason / try-catch / retry / timeout / tick
-;;   tap (Phase 5): side-effecting pass-through (returns input unchanged).
-;;   recover (Phase 5): the fail-VALUE counterpart of try-catch.
-;;   attempt (Phase 6): railway sequence — thread nodes left-to-right but stop at
-;;     the first node that returns a (fail ...) value, returning that failure.
-;;
-;; Phase 3 suspend core (flow-suspend-src):
-;;   The guest Scheme's call/cc is ESCAPE-ONLY (re-invoking a captured k after it
-;;   returns hangs the runtime), so suspend/resume CANNOT re-enter a continuation.
-;;   Instead, durability uses DETERMINISTIC REPLAY: a flow re-runs from the start
-;;   on each resume; suspend points that have already been resolved replay their
-;;   logged value, and the first unresolved suspend escapes back to the driver.
-;;   The entire persisted state is the replay log (plain (tag value) data), which
-;;   survives process restart — no live continuation is ever serialized.
-;;
-;;   (suspend tag)  — if tag is in the replay log, return its value; else escape
-;;     to the driver as (flow-suspended tag). tags must be unique & deterministic
-;;     across replays. ALL effects/non-determinism must go through suspend so their
-;;     results are logged (otherwise they re-run on every replay).
-;;   (flow-drive flow input log) — run flow with the given replay log; returns
-;;     (flow-done result) or (flow-suspended tag).

-;; This is **the independent implementation** referenced by

-;; the eventual sister kit; this file's structures are the Phase 5
-;; "first-consumer" cut.
-;;
-;; v0 concurrency model — IMPORTANT
-;;
-;; SX has no first-class continuations exposed to guest code, so we
-;; can't suspend a goroutine mid-statement. v0 runs `go f()` SYNCHRO-
-;; NOUSLY (it's an immediate call whose return value is dropped). This
-;; preserves the right semantics for patterns where the spawned
-;; goroutine simply pushes to a channel that the main goroutine then
-;; receives — because the spawned goroutine runs to completion first
-;; and leaves the value in the channel buffer.
-;;
-;; True preemption with blocking sends/recvs is a Phase 5b refinement.
-;; The sister-plan diary tracks the design insight (single
-;; sched-spawn primitive, channel-op direction tag) so the eventual
-;; kit doesn't bake in v0's synchronous limitation.
-;;
-;; Channel representation
-;;
-;;   (list :go-chan ACCESSORS-FN-LIST)
-;;
-;; ACCESSORS-FN-LIST is a list of closures sharing a mutable buffer
-;; and a closed flag. The closures expose:
-;;   index 1: send-fn     — (lambda (val) ...)
-;;   index 2: recv-fn     — (lambda () val-or-:empty)
-;;   index 3: closed?-fn  — (lambda () bool)
-;;   index 4: close!-fn   — (lambda () ...)
-;;
-;; Channel identity: distinct calls to go-make-chan produce closures
-;; with distinct identity — `(= ch1 ch2)` is false for distinct
-;; channels, matching Go spec § Channel types.

-;; lib/go/std/strings.sx — Go's `strings` package, v0 subset.
-;;
-;; Exposed as `go-std-strings`, a (:go-package "strings" ENTRIES) value.
-;; Register with `(go-env-extend env "strings" go-std-strings)` to make
-;; `strings.X(...)` call sites work in evaluated Go code.
-;;
-;; Each entry is (FIELD-NAME (list :go-fn PARAMS BODY)) — the same
-;; shape user-defined Go functions get. Bodies are written in SX
-;; directly via go-builtin closures wrapping host-level string ops
-;; for speed, OR as parsed Go source for fidelity. v0 uses
-;; go-builtin wrappers — simpler and fast.

-;; lib/go/types.sx — Go bidirectional type checker.
-;;
-;; Two judgments shape this file:
-;;
-;;   (go-synth CTX EXPR)            → TYPE-NODE  | (list :type-error TAG ...)
-;;     Given a context and an expression, produce a type.
-;;
-;;   (go-check CTX EXPR EXPECTED)   → :ok        | (list :type-error TAG ...)
-;;     Given a context, expression, and expected type, verify compatibility.
-;;
-;; The two judgments are mutually recursive. Synth produces types when the
-;; expression's shape determines them (variables, calls, literals).
-;; Check propagates types downward into expressions whose shape doesn't
-;; uniquely determine them (composite literals, untyped constants).
-;;
-;; Type representations reuse the parser's :ty-* AST nodes from
-;; lib/go/parse.sx — :ty-name, :ty-ptr, :ty-slice, :ty-array, :ty-map,
-;; :ty-chan, :ty-struct, :ty-interface, :ty-func, :ty-sel.
-;;
-;; Context: an association list of (NAME TYPE) bindings. Per-block scope
-;; via a fresh extension on entry.
-;;
-;; **Independent implementation.** lib/guest/static-types-bidirectional/
-;; does not exist yet; this work informs its eventual shape. Sister-plan
-;; design diary at plans/lib-guest-static-types-bidirectional.md tracks
-;; the chiselling insights as Phase 3 progresses.

-;; identity/cache.sx — a delegated grant-verification cache, mirroring the
-;; Redis-cache pattern apps use in front of grant verification.
-;;
-;; The cache is a process wrapping a token registry. introspect() is
-;; memoised; issue/issue_grant/refresh/revoke pass through. The danger
-;; with any cache is staleness: a revoked token must NOT keep reading
-;; valid out of the cache, not even for a millisecond (the loop's hard
-;; rule). We get that for free with GENERATION invalidation:
-;;
-;;   - each cache entry records the generation it was written at;
-;;   - a hit requires entry.generation == current generation;
-;;   - any state-changing op that can invalidate an existing token
-;;     (revoke — which cascades to a grant; refresh — whose reuse cascades)
-;;     bumps the generation.
-;;
-;; So a single revoke instantly invalidates every cached positive: the
-;; next introspect is a miss and re-validates against the live registry,
-;; which returns {inactive}. Revocation stays real; the cache only ever
-;; accelerates the steady state, never overrides a revocation.
-;;
-;; stats() -> {Hits, Misses} so callers can see the cache is live.

-;; This is the loop's central architectural rule made concrete:
-;; AUTHENTICATION is identity's job; AUTHORIZATION is acl's. A request is
-;; checked in two stages, and the order matters:
-;;
-;;   1. identity proves WHO via the opaque token (introspect). If the token
-;;      is inactive, the answer is {error, unauthenticated} — a 401. acl is

-;;      question.
-;;   2. only for an authenticated subject does identity construct the
-;;      permission query {Subject, Scope, Action, Resource} and HAND IT OFF
-;;      to acl. acl returns permit | deny; deny is {error, forbidden} — a
-;;      403. identity itself never decides permission.
-;;
-;; The real decider is acl-on-sx (Datalog), which runs as a different
-;; guest language on SX and is wired in at the integration layer. Here the

-;; identity/device.sx — the device authorization grant (RFC 8628).
-;;
-;; For input-constrained devices (TVs, CLIs): the device gets a device_code
-;; + user_code, the user approves out-of-band on another device, and the
-;; device polls the token endpoint until it flips. The poll status machine
-;; is RFC 8628 §3.5:
-;;
-;;   authorize(ClientId, Scope) -> {ok, DeviceCode, UserCode}
-;;   approve(UserCode, Subject) -> ok | {error, ...}   (the human's browser)
-;;   deny(UserCode)             -> ok | {error, ...}
-;;   poll(DeviceCode) ->
-;;     pending  -> {error, authorization_pending}
-;;     denied   -> {error, access_denied}
-;;     approved -> {ok, Token}        (device code is then single-use)
-;;     consumed -> {error, invalid_grant}
-;;     unknown  -> {error, invalid_grant}
-;;
-;; Tokens are grant-backed (token.sx) so revocation stays real. Device-code
-;; expiry and slow_down (poll-rate limiting) are deferred — the substrate
-;; has no wall clock and the core status machine is the security-relevant
-;; part; introspect via token.sx already honours token TTL.
-;;

-;;   [{DeviceCode, UserCode, ClientId, Scope, Status}]
