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.

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.

notify.sx: reminders + digests as durable flows over an injected transport.
A flow requests delivery (suspend); the host dispatch sends and resumes with
the outcome. At-least-once + idempotent (transport dedups by msg id; replay
logs outcomes). Retry rides suspend/resume with distinct per-attempt tags,
bounded by maxn. Digest delivers a batch with per-message outcomes.
182/182 green. Delivery core is the delivery-on-sx extraction seam.

ticket.sx: checkout-request (events->commerce) + payment-result
(commerce->events) wire shapes — commerce imports the contract. ev/request-
ticket! holds a seat + emits a checkout request; ev/settle-payment! confirms
on :paid, releases on failure/expiry. Idempotent; late paid for a vanished
hold -> :paid-but-no-hold (refund signal). 175/175 green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Booking stream gains :hold/:confirm/:release; fold tracks per-actor seat state
(:held/:confirmed). A held seat counts toward capacity so a pending payment
can't be oversold. ev/hold! (capacity-safe), ev/confirm!, ev/release!,
ev/seat-state. Holds race test mirrors the booking race. 144/144 green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Booking stream carries :booking/:cancel events; live roster is the folded
replay so cancelling frees a seat and capacity reopens. ev/cancel! (retrying
append-expect), no-op on unbooked, cancelled actor may re-book. Capacity count
is folded roster size. 110/110 green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
booking.sx: per-occurrence append-only stream, roster = replay. Booking
decided against an observed (roster, last-seq) snapshot, committed via
persist/append-expect — atomic check+append, no overbooking, no lock.
Explicit last-seat race test: two bookers, one booked, one conflict, roster
capped. Idempotent per actor. 97/97 green.

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?).
Finds gaps, skips too-short gaps, half-open at edges. 59/59 green.

New adversarial/cross-phase coverage: diamond resource+group hierarchies
(deny wins per path), chain inheritance + leaf deny, cycle termination,
multi-peer delegation, fact validation, audit snapshot/restore round-trip.
Adds acl-validate-facts/acl-facts-valid? (schema) and acl-audit-snapshot/
restore!/copy (audit). Fixed acl-audit-restore! rebuilding the live log via
map (append! silently no-ops on map-derived lists).
Suite is prover-free: a substrate JIT bug loops the recursive proof
reconstructor on deep chains in warm processes (documented in Blockers);
acl-permit? is unaffected. 145/145.

The shared durable-state substrate (lib/persist) other subsystems build on:
log + kv facets over an injectable backend, projections, subscriptions,
snapshots + compaction, optimistic concurrency, a durable backend over the
kernel perform IO boundary (blobs by reference), plus extensions (materialized
views, kv CAS, stream catalog, query helpers, atomic batch, schema-evolution
upcasters, exactly-once append, global commit ordering) and a worked ACL
reference migration. 201/201 tests across 20 suites. Durability awaits the
host-side storage adapter (tracked in the plan's Blockers; loops/host-persist).

mod-sx (Prolog) and acl-sx (Datalog) converged on the same module shape but run
on different engines. Only the audit log + fed trust/outbox shapes truly share;
extract at the architecture-merge point refactoring both consumers atomically,
not unilaterally from a loop branch.

166/166 across 11 suites, Phases 1-8. Combinators (sequence/parallel/branch/attempt/
map-flow/while/until + retry/timeout/try-catch/recover/tap/fail-model), durable
suspend/resume via deterministic replay (guest call/cc is escape-only), crash
recovery, fed-sx distribution (remote-node/failover/replication/handoff), operational
API + hygiene, and a host integration ABI + reference driver for art-dag / human-in-
the-loop. New lib/flow/** only; imports lib/scheme read-only.
Document the one gap to real durability: a hosts/ servicer for the persist/*
IO ops. Includes the silent-data-loss repro (durable-backend currently no-ops
under sx_server's default resolver), the full op contract table, hard
invariants (monotonic last-seq, etc.), the blob adapter shape, where to
register in sx_server.ml, and an acceptance test (swap transport, run durable +
recovery suites against real storage, survive a real restart).

examples/acl.sx: a tested template migrating an ACL-grants store from a
hand-rolled ephemeral map to persist — grants/revokes as events, current set as
a projection, O(1) checks via a materialized view, audit via read-window.
Header carries the BEFORE->AFTER diff. Proves grants survive restart on the
durable backend (the capability the BEFORE version lacked). The pattern other
subsystem loops copy; does not touch the real lib/acl. 201/201.

global.sx: persist/gappend records a pointer in a reserved $global index whose
seq is the global commit position; read-global/project-global replay every
event in commit order; global-from for incremental consumers. Opt-in (plain
append untouched); $-prefixed streams now reserved + hidden from the public
catalog (streams-all reveals them). Gives feed its unified timeline.
Deterministic across restart. 191/191.

mod/triage-pipeline domain r reports actor composes domain-policy decision →
explanation → AP activity → wire into one bundle. Integration test runs the whole
federated path across 5 modules (decide → wire → peer → trust-gated apply),
confirming the module-by-module subsystem composes end to end. +15 tests.

mod/defrule collects trailing conditions via &rest; mod/ruleset assembles rules.
No macro needed — conditions are plain data, fn supports &rest here. Produces
structurally identical rules to mk-rule (asserted) and works in the engine
unchanged. Closes the roadmap's original defrule surface. +11 tests.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
mod/register-policy! domain rules + mod/decide-in domain r reports give each
rose-ash domain its own rule set; unregistered domains fall back to default-rules
(never unmoderated). Same spam report → remove under a strict market policy, hide
under blog default. Engine already took rules as a param, so this is registry +
fallback, no engine change. +14 tests.

Completes the host ABI from work-queue to driver loop: the host supplies only a
(kind payload) -> answer dispatch fn; flow-drive-host services one tick of pending
requests, flow-run-host ticks until quiescent (bounded). Tested via the art-dag
render -> human-review -> publish pipeline driven entirely by flow-run-host. The
art-dag integration is now: define dispatch, call flow-run-host. 166/166, 11 suites.

mod/decision->activity maps a decision to a moderation verb (remove→Delete,
ban→Block, hide/escalate→Flag, keep→no activity) shaped like an AP activity,
preserving the precise action. mod/decisions->activities batch-exports dropping
keeps. With wire (Ext 14) + fed trust (Phase 4) the federated moderation path is
end-to-end: decide → activity/wire → peer → trust-gate → apply. +17 tests.

idempotency.sx: persist/append-once appends at most once per (stream,
idempotency key), returning the same event on a repeat. The marker lives in the
kv facet, so idempotency holds across a restart (verified on durable).
persist/seen? check. 180/180.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
upcast.sx: register a pure (event -> event) upcaster per type in an immutable
registry; read-upcast/project-upcast lift legacy events to the current shape on
read so projections see one shape (no version branching, no history rewrite).
upcast-data helper merges new :data fields. 171/171.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
batch.sx: persist/append-batch commits (type at data) specs as one contiguous
block; persist/append-batch-expect checks the stream is still at expected
before writing any event, so the batch is all-or-nothing under a concurrent
writer (conflict is a value, not a partial write). 162/162.

The seam for hooking flow to art-dag and human-in-the-loop later. (request kind
payload) suspends with a typed (flow-request kind payload) envelope and returns the
host's resume value; await-human/await-render sugar. (flow-host-requests) is the
host work queue: (id kind payload) for every suspended flow awaiting a host effect;
request?/request-kind/request-payload parse a tag. Tests include the art-dag-shaped
driver loop (render -> human-review -> publish). Host owns IO+persistence; flow only
requests (replay-safe). 162/162 across 11 suites.

(:any (list c1 c2 ...)) compiles to Prolog disjunction (g1 ; g2 ; ...), completing
the condition boolean algebra (AND via :when list, :not, :any). cond->goal
recurses so combinators nest arbitrarily; the proof tree shows the compiled
disjunction verbatim. Maps onto Prolog's control constructs rather than
reimplementing boolean logic in SX. +10 tests.

query.sx: read-between (seq range), read-since/read-window (by :at),
read-by-type, read-where, count-where. Pure scans over persist/read for audit
windows, type filters, since-cursors. 152/152.

New backend op :streams (from seq high-water marks, so compacted streams still
list), threaded through mem-backend + durable serve/io-backend. catalog.sx:
persist/streams, stream-count, stream-exists?, total-events. 143/143.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
kv.sx: persist/kv-cas sets a key only if its current value equals expected,
else returns {:conflict :expected :actual}; persist/kv-put-new is create-only.
The kv analogue of log append-expect — atomic current-state for sessions, acl
grants, stock counts. 133/133.

Replaces the bespoke 116-line conformance.sh with a conformance.conf + 1-line
exec shim, reusing lib/guest/conformance.sh. Surfaced + fixed a silent undercount:
the old awk extractor reported pipeline=40, but pipeline.sx has 152 assertions —
real total is 562/562, not 450/450. Driver reads counter globals directly.

mod/decision->wire emits a versioned pipe-delimited line (MOD1|r1|hide|spam-hide);
mod/wire->decision parses it back (mod/wire-valid? guards). split-char built over
slice/len (loaded env has no split). Integration test runs the full federated
path: serialize → wire → deserialize → fed-receive-decision trust-gating
(untrusted→advisory, trusted→applied). +16 tests.

view.sx: persist/view bundles stream + fold + snapshot name; view-attach
subscribes it to a hub so each publish refreshes the snapshot incrementally,
making view-peek an O(1) current read. view-value always folds the tail so it
is never stale. The consumer read-model abstraction (feed indices, audit
rollups, search counters). 122/122.

recovery.sx: 6-test end-to-end crash/restart of an order ledger (log +
subscription kv read model + snapshot + compaction + invoice blob ref) on the
durable backend; everything survives a restart over the same disk + content
store, seq continues, two restarts converge. Migration notes (mem → durable
under a live subsystem) added to the plan. Roadmap done, 111/111.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
blob.sx: a blob ref is {:cid :size :mime}; the blob store is a separate
injected dependency (perform in prod, mock content store in tests).
persist/blob-store puts bytes and returns only the ref; bytes live in a
content-addressed store (artdag/IPFS). Tests assert refs in log/kv never carry
the bytes + content-address dedup. 105/105.

durable.sx: io-backend with an injectable transport — persist/durable-backend
performs each op as {:op "persist/..." :args (...)} (kernel suspends, host
resumes); persist/mock-durable services via persist/serve over an in-memory
disk. Identical request shapes mean the whole facet/projection/snapshot/
compaction stack runs unchanged on the durable backend. Crash/restart replay
recovers log+kv+snapshot. 91/91.

Composes lifecycle (Phase 3) with time (Ext 12): a timed-case pairs a case with
its state-entry tick; mod/overdue? flags pending cases (open/triaged/appealed)
past a deadline; mod/sla-sweep returns the breached report ids. Terminal states
never breach. Pure overlay — lifecycle stays timeless, caller stamps entry. +15 tests.

Reports gain an :at tick (deterministic, supplied). mod/decide-temporal counts
reports about a subject within [now-window, now], asserts burst_count/2, and a
(:burst-at-least K) rule fires only on a real burst. 3 reports at 10/11/12 → hide;
3 at 1/2/12 (window 5) → keep, while the plain count rule escalates both. Fifth
report field threaded through rebuild helpers, non-breaking. +15 tests.
