New artifacts:
arts/timr — runtime timer scheduler (singleton-per-App, never global).
Engine + Active split. Race-safe via (id, key, version) guard against
stale native callbacks, async tasks resolving after cancel/replace,
interval ticks scheduled after dispose, and ack-style timeouts. Per-
entry AbortController; intervals reuse the signal across ticks.
awaitTask:true (default, no overlap) vs awaitTask:false (fire-and-
forget cadence; failures don't stop the interval — semantic frozen).
Recursive setTimeout for intervals. scheduleAt(past) → delay 0 (no
error). Fake-clock injectable for deterministic tests. Pure
computeBackoffDelay helper. 50 server tests + 7 browser tests + full
README + DESIGN_TIMR + interactive test page at /test/timr.
arts/sess — session lifecycle with three generics
(TUser/TCredential/TData) plus optional SessionActor metadata
(kind/source/confidence — orthogonal axis to identity).
Tagged AdoptResult/RefreshResult/RevokeResult; never void.
Generation guard against stale refresh from local cancel, cross-tab
storage events, or re-adopt. onRefresh contract (null=fatal,
throw=transient). onRevoke replaces revokeUrl (consumer controls
fetch; engine just gets boolean). Default scope: 'global' when
onRevoke configured. INITIAL_SESSION sync dispatch on subscribe.
BroadcastChannel payload: {type, event, generation} only — never
tokens. SSR cookie reader validates invariants. withAutoRefresh
helper, 401-retry hook with applyAuth + loop guard, JWT exp helper.
103 tests (60 server + 5 browser + 38 actor/error/etc) + README +
DESIGN.md + test page at /test/sess.
arts/http — HTTP client with Standard Schema body validation, retry
+ Retry-After, attempt + total timeout via AbortSignal composition,
hooks (beforeRequest/beforeRetry/afterResponse/beforeError),
tagged HttpResult. Test page at /test/http.
arts/conn — DESIGN_CONN.md only (no implementation yet).
aapp:
- App.createActiveSession<TUser, TCredential, TData>(opts) factory
auto-injects App.Logger; throws SessAlreadyCreatedError on second
call. App.Sess getter exposes the active session (undefined until
first call). Auto-disposed by App.dispose().
- App.Timers integration deferred to timr Fase 3.
libs/days:
- toEpochMs(value) — permissive coercion (number | Date | string) →
epoch ms. Exposed alongside the existing day/calendar helpers.
Other:
- sium examples moved to _examples/ (excluded from public surface).
- sium-provider.svelte test removed (port pending; tracked elsewhere).
- libs/env.ts — DEV flag single source of truth.
- Various README touch-ups across artifacts.
All artifacts: 1021 server tests + 12 browser tests; svelte-check + ESLint
clean. The 9 server "errors" are pre-existing jsdom missing — unrelated.
