audit.sx is an append-only ledger process. token.sx gains start/1(Audit)
and emits an event on every grant transition (issue, refresh, revoke —
including reuse-triggered revoke); start/0 stays unaudited so existing use
is unchanged (token.sx has no compile-time dep on the audit module, it just
sends to a pid). The ledger answers (identity/audit subject) via
audit/actions/count/all, chronological. In-memory event stream; persist
backing is a later Erlang<->persist bridge, out of scope. 111/111.

cache.sx — a process wrapping the token registry, memoising introspect.
Revocation stays real via generation invalidation: any revoke/refresh bumps
a generation counter, so every cached positive instantly becomes a miss and
re-validates against the live registry. A revoked token never reads valid
out of cache, not for a millisecond. stats() exposes hits/misses. New
tests/cache.sx. 101/101.

ledger.sx — each order is an append-only persist stream "order/<id>";
status/total/paid/recon are folds over events (ledger = source of truth).
order-pay / order-refund are idempotent via persist/append-once keyed on the
payment ref, so a replayed SumUp webhook records once. order-recon-of
classifies unpaid/ok/underpaid/overpaid on net vs total; ledger-mismatches
finds genuine paid != ordered across streams. minikanren+scheme/flow+persist
verified coexisting in one process. Total 132/132 across 8 suites.

Step 7c made outbox depend on follower_graph + delivery, breaking
four tests that didn't load those modules. Background gate
revealed the failures after 7c had already been pushed.
Loads added:
auto_accept.sh — epoch 12: delivery (follower_graph
was already loaded at epoch 10)
nx_kernel_multi.sh — epochs 5+6: follower_graph + delivery
(existing modules shifted: outbox 5->7,
nx_kernel 6->8). Check 6 -> check 8.
http_publish.sh — epochs 100+101: follower_graph + delivery
(high epoch numbers to avoid collision
with test epochs at 10+)
http_publish_fold.sh — epochs 100+101: same pattern
All four green at 9/9, 26/26, 10/10, 10/10. No behaviour change
in outbox or downstream code; pure test-setup follow-up to 7c.
Conformance 761/761 (confirmed post-7c).
membership.sx — coop membership as a guarded state machine
(none→pending→active→lapsed⇄active, any→revoked terminal); invalid
transitions return explicit {error, CurrentStatus}, never silent no-ops.
project(Subject, App) renders the one canonical state into a per-app claim
({member,Tier,App} / {pending,App} / {lapsed,App} / {denied,App} /
{non_member,App}) — identity reports what the membership is; acl decides
whether the app should honour it. New tests/membership.sx. 92/92.

ev-next-free finds the earliest free slot >= after for a duration within a
horizon, probing 'after' + busy-interval ends via the busy_in rule (ev-free?).

oauth.sx now owns a session registry. establish creates a subject session;
silent_authorize (OIDC prompt=none §3.1.2.1) asks "does this subject have a
live session?" — if yes it mints a code skipping consent, bound to client +
redirect_uri + PKCE exactly like a consented code; if no it returns
login_required (a negative state, not a login redirect). One session serves
many clients; end_session closes the fast-path. New tests/sso.sx. 75/75.

exchange now issues an access+refresh pair (RFC 6749 §4.1.4/§5.1) via
token.sx issue_grant; added the refresh grant (§6) delegating to token
rotation. End-to-end: code-exchange → refresh → introspect (active),
refresh-token reuse rejected (invalid_grant), and revoke-then-refresh
blocked by grant cascade. oauth 17/17, 65/65.

outbox:publish/2 now computes the audience-resolved delivery set
after sign + log and stashes it in the Result proplist as
{delivery_set, [ActorId, ...]}. Step 8's delivery-queue worker
reads it off the publish result.
New compute_delivery_set/3(Request, Signed, Context):
- Pulls :follower_graph from Context (defaults to empty graph)
- Calls recipients_envelope/2 to synthesise a minimal envelope
from Request's :to / :cc + Signed's :actor
- Routes through delivery:delivery_set/3 unchanged
The envelope construct/4 surface doesn't carry :to / :cc (only
type / actor / published / object), and changing that ripples
through every envelope shape test. recipients_envelope/2 keeps
the compute boundary local to outbox.
4 new cases in outbox_publish.sh (17/17 total):
- Result :delivery_set empty default
- explicit :to -> [bob] in set
- followers symbol expands via Context :follower_graph
- self-suppression (alice in :to drops to []bob])
Module loads rebumped: follower_graph + delivery added as
dependencies; outbox shifts from epoch 5 to epoch 7. Internal
sx_server timeout bumped 240s -> 480s to fit the larger module
set.
Step 7 fully closed (7a delivery module + 7b public expansion
+ 7c outbox integration). Federation now has the end-to-end
audience resolution: an outbound activity's :to / :cc plus any
follower_graph expansion becomes a deduped recipient list ready
for Step 8 to dispatch.
Conformance running + adjacent gate running.
quote.sx — cart-quote composes the pipeline into a deterministic
{:subtotal :discount :tax :total :codes} with total = subtotal - discount +
tax. Explicit tax policy: tax on gross per-line amounts (discount reduces
payable, not the tax base). This quote is the value the Phase-3 order flow
carries. Total 112/112 across 7 suites.

The grant {Subject,Client,Scope,Status} becomes the unit of authorization
and cascade; access + refresh tokens reference it. issue_grant returns an
access+refresh pair; refresh (RFC 6749 §6) supersedes the presented refresh
token and mints a fresh pair; reusing a superseded refresh token is treated
as theft (RFC 6819 §5.2.2.3) and revokes the whole family, killing the live
descendant. revoke of any token cascades to the grant. All prior token
behaviour preserved. token 18/18, 62/62.

stack.sx — precedence as a separate selection layer, not in the rules.
Exclusivity = unordered code pairs; valid-stackings enumerates every legal
subset of applicable promos; best-stacking deterministically picks max total
discount (stable on ties); stacking-by-totalo answers "which legal stacking
yields total D?" backward. Member vs guest falls out of applicable-promos.
Completes Phase 2. Total 99/99 across 6 suites.

promo.sx — four promo types as tagged tuples; per-promo discount is pure
integer arithmetic, but enumeration is relational: promo-discounto and
promo-applieso run forward ("which codes apply, for how much?") and backward
("which code yields this discount?"). project grounds the membero-bound promo.
applicable-promos / promo-amount-for deterministic helpers. Total 83/83.

identity:start() spawns one coordinator owning the token table + session
registry and exposes the whole-domain ops. The coordinator is the owner
sessions notify on idle timeout, so an expired session deregisters itself
— timeout-driven, never swept. verify/2 answers identity only ({active,
Subject, Client, Scope}); permission is delegated to acl. 39/39.

Directory process holding (SessionId, Subject, Client, Pid) rows. Answers

Token table is a process; the token is an opaque make_ref carrying no
information. introspect() is a live table lookup every time, so
revocation is real (RFC 7009 §2): a revoked token reads {inactive} on
the next introspection with no validity window. Reply shapes follow
RFC 7662 §2.2 ({active, Subject, Client, Scope} / {inactive}).

Session is an Erlang process holding {subject, client, status}. lookup/
touch/expire/revoke are messages; expiry is the process's own
`receive ... after Ttl` timeout (RFC-agnostic; no global sweep), which
notifies the owner and tombstones. Tombstoned sessions answer lookups
with an explicit {error, expired|revoked}, never a silent dead mailbox.
Adds the conformance harness + scoreboard.

relational accessors (producto/varianto/stocko, derived priceo/classo/
unit-priceo) usable forward and backward, deterministic catalog-price/
-class/-has? helpers. Money is integer minor units. conformance.sh runs
suites on the miniKanren stack and emits scoreboard.{json,md}.

delivery:expand_audience(public, Sender, Graph) now returns the
sender's followers (same as the followers symbol). Per design
§13.4 the practical Public fan-out semantics for an open social
network is 'every follower of the publishing actor'. The
explicit shared-inbox peer-instance model (Mastodon-style
per-instance broadcast) defers to v3 when there's a real
known-peer-instance registry to drive it.
19/19 in delivery_set.sh:
- public symbol now expands to sender's followers (epoch 19,
updated from v2 placeholder)
- public with empty follower-graph -> [] (epoch 28)
- public + followers in same audience dedupe (epoch 29)
Conformance 761/761.
New next/kernel/delivery.erl computes the audience-resolved
deduplicated recipient list for an outbound activity.
delivery_set/2(Activity, KernelState)
delivery_set/3(Activity, KernelState, FollowerGraph)
Returns a deduplicated list of ActorId atoms. Step 8 will
resolve each entry to {PeerInstanceUrl, ActorId} via the
peer-actors cache.
Sources unioned then deduped:
- :to field (single ActorId or list, atoms or audience symbols)
- :cc field (same shape)
- audience-symbol expansion:
followers -> sender's followers from follower_graph
public -> [] for v2 (Step 7b layers known-peer-instance set)
Self-delivery suppressed every time the sender's ActorId appears
in the set.
Module lives in its own file (not inside outbox.erl) so Step 8's
delivery-queue gen_server has a clean home alongside it.
17/17 in next/tests/delivery_set.sh covering:
- empty activity -> []
- single :to atom + list :to recipients
- :to + :cc unioned
- self-suppression
- duplicate / cross-field dedup
- followers symbol expands via follower_graph state
- empty follower-graph -> []
- public v2 placeholder -> []
- mixed explicit + followers
- collect_recipients raw flat
- suppress_self drops every match
- dedup preserves first-occurrence order
- expand_audience pass-through for plain ActorId
Conformance 761/761. 86/86 across 6 Step-7-adjacent suites
(follower_graph, follow_lifecycle, auto_accept, inbox,
nx_kernel_multi, outbox_publish).
A synonym map [(Term,[Term])] expands a query term to itself + synonyms
