- Duration literals now accept s/m/h/d/w (was m/h/d/w): 'BEHAVES { ttl 30s }'
is 30s, and 'within 30s' temporal expressions parse.
- Definition fields are REQUIRED by default ('field: type'); 'field: type?'
marks a field optional. addNode enforces presence on insert, getSchema
exposes per-field requiredness, and updateNodeData still validates the
provided fields' types.
- Provider-returned edges are validated against the fact's declared typing:
a value-carrying fact must return { value, possibility } with a value of the
declared type (bare-number shorthand is rejected); a non-value fact must not
carry a value; and every possibility must lie in [0, 1]. Violations throw a
clear provider-authoring error instead of silently injecting malformed edges.
Tests: DSLRuntimeTyping (duration units, required-field enforcement, schema
requiredness, value-type + shape + possibility validation).
- check() gains cacheProviderResults (per-check option + policy default): the
provider cache is a STORE-RETRIEVAL cache (wall-clock), independent of the
caller's decision { now }; callers who pin time or want fresh retrieval can
opt out per-check or globally.
- The generator now rejects a comparator evidence referenced at a NON-final
chain position (a comparator compares values at (src, candidate) but
provides no candidate set, so it cannot enumerate intermediate nodes).
Final-position comparators still lower to condition steps.
Tests: cache bypass (per-check + policy), comparator final OK / intermediate
error.
Automatically-retrieved facts (balances, sessions, etc.) are now cached with
a time expiry so repeated checks don't re-invoke the underlying data store.
- check(): registered providers cache their normalized edges per
(relation, subject, object) with a TTL; a fresh entry is reused without
re-invoking the provider. Per-check factProviders are one-off observations
and stay cache-transparent (no read, no write).
- TTL resolution: DSL-declared 'BEHAVES { ttl <duration> }' on a fact >
setFactTTL(relation, ms) > policy.providerCacheTTL (default 30s; 0 disables).
- Grammar: facts may now declare a freshness window via
'fact balance(user, amount) BEHAVES { ttl 1h }' (previously BEHAVES only
accepted 'AS edge|transitive|hierarchical|symmetrical_graph'). The runtime
indexes it as the fact's ttlMs.
- registerFact/unregisterFact, graph mutations (add/update/remove node or
relation), and invalidateProviderCache(relation?) keep the cache consistent.
- Injectable clock (default wall clock) drives cache freshness, mirroring the
core's unpinned-clock contract.
Tests: DSLRuntimeCache (reuse within TTL, expiry re-invoke, per-check
override transparency, registerFact invalidation, mutation invalidation,
per-relation/all invalidation, policy default, DSL-declared 1h TTL).
