bcae483 made the cache a delivery scheduler (tickets, _deliveryGate turn
waits, per-thread delivery queues). It deadlocked inside CultLib: a load's
delivery reaching a CultNetDatabaseSubscriptionServer observer that needs
_lifecycleGate, while a subscribe's demand handler holding that gate writes
the cache and waits for the delivery's turn.
The cache now owns order as data. Every admitted change takes the next value
of a per-cache in-memory sequence under the gate, published as
CultCacheDocumentChange<T>.Sequence. Delivery is the 544c087/b653f68 rule:
each call publishes its own changes on its own thread after releasing the
gate; nothing waits on another call's delivery. Cross-thread delivery order is
not guaranteed.
Deleted: ticket counter, _delivered, _deliveryGate, Monitor.Wait turns,
per-thread delivery queues, per-ticket catch-all, and the save-order contract
text with its observer-must-not-block rule.
Consumer: a cache-backed CultMesh document handle hands its observed and
reactive mirrors each snapshot's Sequence; ApplyCanonicalSnapshot drops one
not newer than the last applied.
Tests: SequenceIncreasesInAdmissionOrder,
ObserverWritingTheSameCacheDoesNotWaitOnOtherDeliveries,
SubscriptionDemandHandlerWritingCacheDuringDeliveryDoesNotDeadlock,
WatchRecordIgnoresStaleSequence. The last three time out on bcae483.

- NetworkingTests.CultNetPutInsideCommitPublishesOnlyAfterCommit: a record
staged in a batch reaches no CultNet observer before the store commits; a
put made while staging is its own write. Chosen over refusing CultNet writes
inside a batch, which would need ambient "inside a batch" state.
- Interop peer mode write-routed <catalog.cc> <run.cc>: cultcache.interop-note
routes to the catalog file, cultcache.interop-run-note to the run file, one
record each.
- store-composition contract: the C# column reads implemented for routing,
attach, schema, lookups, globals, batch and conditional commit; overwriting
a store is open, remove, upsert, flush. persistence-format: C# implements
batch and conditional commit.
- tests README lists the new suites.

ExecuteTransactionAsync (both overloads), RequireTransactionsForAuthoritativeWrites,
EnsureAuthoritativeTransaction and the AfterCommit deferral had no consumer
outside CultNetDatabase_RequiredTransaction_DefersRawPutPublicationUntilCommit,
deleted with them. Writes publish immediately, as they already did outside a
transaction. The cache's own transaction machinery stays until Cut 3 replaces
it with the explicit batch commit.
