fault.sx run-safe: a node op may return (artdag/fail reason); failure is confined
to that node + downstream dependents while independent branches compute, and failed
results are never cached, so retry after a fix recomputes only the failed closure
and hits the good nodes. fault 14/14, total 158/158.

stats.sx reports hit-ratio, cost-weighted work-recomputed/work-saved,
savings-ratio, and exec-summary over an execution record. Verifies cold (0
saved), warm (all saved), and incremental (saved = unchanged, ran = dirty
closure). stats 12/12, total 144/144.

artdag/optimize entries outputs fusible? fuses the entry list then DCEs against
the output names — sinks survive fusion (never absorbed), so output-equivalent
with fewer nodes. optimize 22/22, total 132/132.

serialize.sx emits a topo-ordered (id op inputs params commutative) record list
that survives write/read (string-keyed node dicts do not; empty inputs read back
as nil and are normalized). wire->dag reconstructs a runnable dag by content-id;
wire-verify recomputes ids to reject tampering. dag->string/string->dag for text
transport. serialize 13/13, total 128/128.

optimize.sx adds three result-preserving passes: dce (keep outputs + ancestors,
preserve ids), cse (==build; structural sharing is free from content addressing),
and fuse (collapse 1-to-1 fusible unary chains into an artdag/pipeline node fed by
the chain head's input; leaves/fan-out/non-fusible ops never fuse). fusing-runner
replays pipeline stages, output-equivalent to the unfused dag. optimize 18/18,
total 87/87.

execute.sx folds a plan, runs each node via an injected runner (perform in
prod, op-table in tests), and memoizes results in a lib/persist kv backend
keyed by content-id. Incremental recompute falls out of content addressing:
a leaf change reassigns ids across its dirty closure, so re-running hits the
unchanged nodes and recomputes only the closure (cold 5 -> rerun 0 -> change 3).
Cross-dag subgraph sharing verified. execute 15/15, total 69/69.

plan.sx schedules a dag into Kahn-wave batches (parallel-safe), splits waves
wider than a cap into sub-batches, and plans incrementally over the dirty
closure only (out-of-set deps treated as satisfied cache hits). plan 18/18,
total 54/54.

analyze.sx projects DAG edges to (edge in out) facts and runs recursive
reachable rules for deps-of/dependents-of/reachable-from/ancestors-of, plus
dirty-closure (dirty(Y):-edge(X,Y),dirty(X)) for incremental recompute. Keystone:
changing a mid node dirties only it + downstream. analyze 16/16, total 36/36.

timezone.sx: wall-clock LOCAL <-> absolute UTC. :fixed + :dst zones (std/dst
offsets + UTC transition rules, EU-style, no IANA DB) computed via calendar
helpers. ev-event-tz authors in local time; ev-expand expands tz events in
LOCAL time then converts each occurrence to UTC, so a 09:00 weekly meeting
stays 09:00 across a DST change (UTC instant shifts). Predefined utc/london/
paris. Plain events unaffected. 295/295 green.

Reading lib/mod (Prolog) and lib/acl (Datalog) side by side shows the convergence
is in module names only. Federation: opposite trust models (SX registry + decision
sharing vs in-engine Datalog trust facts + fact replication), zero shared code.
Audit: only a ~5-fn core overlaps and it diverges (entry shapes, seq base 0 vs 1,
op sets, mutation idiom) — not worth a shared module under two restricted envs.
Outcome: keep them parallel; revisit only on a third same-model consumer.

fetch abstracts how a peer's agenda arrives: (fetch peer-id ws we) ->
{:status :ok :occurrences} | {:status :error}. ev/federated-agenda-via merges
local + trusted peers fetched via the transport; unreachable peers degrade
gracefully. ev/peer-fetch = in-process adapter; ev/federation-status reports
reachability. A real fed-sx transport drops in unchanged. 278/278 green.

identity_tokens:revoke_app(Subject, Client) revokes every grant a subject
holds for one client at once (audited one revoke per grant), exposed at the
facade as identity:revoke_app. The action counterpart to the grants view —
completing the account-security view+action pairs (sessions/logout_all,
grants/revoke_app, history). Other subjects' same-client grants are
untouched. account 11/11, 233/233.

ev/reschedule-notifications: when an event carries per-occurrence overrides,
reads the roster at each overridden occurrence's original occ-key and emits a
reschedule message per booked attendee (old-start/new-start/new-duration).
Idempotency key = original-key/reschedule/new-start. 272/272 green.

booking-notify.sx walks the booking stream into ordered notifications by kind
(booked/promoted/held/confirmed/released/cancelled/waitlisted). Promotion
detected by folding the waitlist (a booking for a waitlisted actor is a
promotion). id=occ-key/seq -> idempotent re-derivation, no double-ping.
Connects ticketing to the delivery layer. 265/265 green.

ev-with-override re-times/re-sizes a single instance of a series (keyed by
original start). ev-expand applies overrides after EXDATE/RDATE: agenda
re-sorts, instance moved out of window is dropped (slot vacated), no-op for a
non-occurring start. assoc for immutable event update. 254/254 green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
When full, ev/waitlist! queues actors FIFO (:waitlist/:unwaitlist on the
booking stream; waiting fold independent of the seat fold). ev/waitlist,
ev/waitlist-position, ev/leave-waitlist!. ev/cancel-promote! frees a seat and
auto-promotes the head of the queue to a confirmed booking. Idempotent.
240/240 green.

identity_tokens:grants_for(Subject) lists a subject's active grants as
[{Client, Scope}] (revoked excluded), exposed through the facade as
identity:grants(Subject). Completes the per-subject account-security trio:
sessions (where logged in), grants (which apps have access), history (what
happened). New tests/account.sx. Conformance internal timeout raised to
1200s (22 suites, ~10min — run in background). 229/229.

federation.sx: a peer publishes a schedule; ev/federated-agenda merges local
(origin :local) with trusted peers' agendas, sorted by start, tagged with
:origin provenance. Trust is a peer-id set re-checked per merge; untrusted
peers contribute nothing. Real transport slots behind ev/peer-agenda.
209/209 green — all four plan phases implemented.

register_dynamic generates a client_id + secret server-side and registers
the client, returning {ok, ClientId, Secret} — self-service onboarding
distinct from the manual register_client. A dynamic confidential client can
then use client_credentials; a dynamic public client stays
unauthorized_client. New tests/dynreg.sx. 222/222.

push_authorization_request lodges the authorization params under a
single-use request_uri; authorize_pushed redeems it into the normal consent
flow. Pushed requests reuse the pending store ({pushed, Rec} keyed by the
request_uri ref — distinct from consent req_ids, so no collision and no new
loop state). The pushed binding (client + redirect + PKCE) is still enforced
at exchange. New tests/par.sx. 217/217.
