The per-document isolation refactor (one doc per entity) broke every @data
round-trip against the real broker (0 events readable) — fake-ng unit tests
missed it. Root causes + fixes:
- ngSet.add cannot write to an empty subscription scope ("Set is readonly
because scope is empty") → write each entity DIRECTLY into its own document via
SPARQL (new data/entityWrites.ts: writeEntity/updateEntityField), typing each
field with the correct RDF term per the SHEX shape (else the ORM drops the
entity on read). Reactive set stays read-only; the doc NURI is registered into
useShape({graphs}) for reactive reads.
- Current principal made STABLE and username-derived (urn:festipod:user:<name>),
available immediately at login and invariant — so a Participation's mandatory
fp:user is never empty and identity/cap-owner/connections all key on the same
value.
- Discovery deposits AS the current identity (harness sets current user first).
- Idempotence/deregistration checks made authoritative against the broker;
participantCount persisted via SPARQL. rule_document-per-entity enriched with
these write/read + stable-principal lessons.
Round-trip restored (seed readable, inscription+notif, persistent deregistration,
public discovery all pass in isolation). NOT yet stably green as a full suite:
@data oscillates 15–20/21 — residual failures are environmental (participation-
read fan-out lag on an accumulating persistent test wallet), same class as the
Chromium saturation; not a logic bug. Durable fix (follow-up): non-fan-out
materialized read + per-scenario test-wallet isolation. app build+tsc + lib 89
tests green.
