Guard the Option-B owner-materializer against overlay-form drift: match inbox
deposits to owned events on the CANONICAL base repo id (canonicalEventId strips any
✌️<overlay> suffix), applied at the matching boundary in materializeAttendance /
readRegistrationNotifications and to dedup ownedEventIds (ownedKey). The count is
still WRITTEN on the real owned NURI — a stripped id is never a write/anchor target.
Honest framing: this is DEFENSIVE, not a fix for an active bug. On the current tree
create-time, listMyEntityDocs and the read @id already carry the identical NURI
(readUnion pins the subject to the input NURI, 63ecfee) — verified: the count
converges for an event owned via listMyEntityDocs. A prior investigation's 'never
matches' reading was the seeded-but-not-owned artifact (a prior-run identity owned
the seed → reached via discovery, not ownedEventIds — correct behavior).
Un-@wip the @data convergence scenario (asserts the just-joined uid enters the
owner-derived active set — deterministic despite shared-inbox accumulation); it
now passes. Fix authParticipationCount already landed separately. Doctrine:
knowledge_context-internals (canonical id-form invariant). Build + tsc clean.

Remove the write-isolation violation: joinEvent/leaveEvent no longer write
participantCount on the event doc (a non-owner writing the owner's public doc —
illegitimate in NextGraph). The joiner/leaver only write their own protected
participation doc and DEPOSIT a marker into the event inbox (depositRegistration /
depositLeave).
The event OWNER's session materializes: it subscribes (inbox.watch, doc_subscribe —
no polling) to the inboxes of its OWNED events (ownedEventIds), and on each deposit
recomputes participantCount on its OWN event doc. The count is DERIVED, not
incremented: materializeAttendance derives the SET of distinct active registrations
(new-participant deduped by uid, MINUS leave-participant by regUid/fallback
eventId+userId), count = 1 (host self) + |active set|. A pure function of the inbox
→ broker re-syncs converge, never double-count nor resurrect (idempotent); the write
is guarded (only on change → no loop). Authoritative deleteParticipation preserved
(caveat_participation-deletion).
Because the owner writes its own PUBLIC event doc and every session subscribes to it
(P3), the count round-trips reactively to all — no reload. Owner-offline = eventual
(V1; a future @ng-eventually/service materializes on the owner's behalf).
Real 2-browser e2e (e2e-multibrowser.feature): B registers → A materializes → count
1→2 reactively (no reload) + unknown participant; B leaves → count →1. 14/14 green.
Gates: @data auth 4/4, @data isolation 4/4, build + tsc clean. Doctrine:
knowledge_context-internals (Option B section).

The lib e2e harness proves that on the current broker an anchored
INSERT DATA { GRAPH <plainNuri> {…} } DOES round-trip — the earlier 'explicit GRAPH
writes a phantom named graph the read never sees' claim was false; the '0 entity'
symptom was actually the wallet-bloat hang (caveat_wallet-bloat-hang), not a graph
mismatch. Reframe the no-GRAPH default-graph rule as a simplicity/safety convention,
not a round-trip necessity. Lib/app inline comments asserting the phantom-graph
claim remain to reconcile.

Wire the app read path to the lib's per-doc reactive subscription so a change made
in ANOTHER session propagates without a reload or local action:
- useNgData subscribes the by-need set via subscribeDocs(allReadDocs, bumpRead) —
one doc_subscribe per NURI, per-doc error isolation (never the ORM fan-out). Any
patch (own write or broker-synced from a remote peer) re-runs readUnion.
- Reactive discovery: watchDiscoveredEvents(relist) subscribes the global index →
a new public event from another session enters the read set (and gets its own sub).
- Loop-safe: the sub effect is keyed on a stable sorted-NURI key (readDocKey); a
fire→bumpRead→read never changes the doc set, so no re-subscribe loop. Identity
switch empties the set → clean unsubscribe → rebuild → re-subscribe (no leak).
- readUnion stays the one-shot tolerant reader; subscriptions only trigger re-reads.
Real 2-browser e2e (e2e-multibrowser.feature): B registers → A's EventDetailScreen
shows participantCount 1→2 and an 'unknown' participant WITHOUT A reloading, via A's
doc_subscribe on the public event doc (event-driven). Isolated run 12/12 green.
Count mechanism unchanged (P4/Option-B is next); the joiner still writes the public
event doc's participantCount — which is exactly what the observer sees change live.
Gates: @data auth 4/4, @data isolation 4/4, build + tsc clean.

P1/P2 (lib subscribeDoc + drop polling) landed in @ng-eventually/client c0498a6.
Owner-offline count = eventual for V1, a future @ng-eventually/service takes over
when the owner is disconnected. Reactive hooks are useShape + useDiscrete (no
useQuery); the union-of-N-docs read stays subscribeDocs + re-readUnion (useShape
fan-out hangs). Next: P3 (wire per-doc subscription into the app read path).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Implementation design brief (grounded in current code): reactive reads via a typed
per-doc doc_subscribe wrapper (no polling, no ORM fan-out -> avoids the historical
hang); participant count via option B (joiner deposits into the event inbox, the
event owner materializes into its own event doc's count; option A ruled out --
non-owner append is impossible in NextGraph). Connection-gated identity (else
'inconnu'). Test plan: polyfill low-level doc_subscribe + real 2-browser e2e
reactivity. Phased P1-P6. Open product question: owner-offline eventual count.

Add a pointer in knowledge_nextgraph-stack: the SDK's recommended read is its
reactive useShape hook (subscribe/push, one-shot is the exception); full contract
in @ng-eventually/client packages/client/docs/sdk-reference.md. No NextGraph
internals copied into the app repo — just the pointer.

The shared-wallet stopgap keeps ONE React tree across a faux-logout + re-login
under a different identifier (AccountContext.login only rewrites a localStorage
id; AuthGate never remounts, no page reload). FestipodDataContext's by-need read
set accumulates the current identity's scope docs and was never reset on identity
change, so the PREVIOUS identity's PROTECTED docs (its participations) survived in
the new identity's read set and leaked through the union read — the in-memory cap
gate can't filter a doc it doesn't govern this session. Symptom: user B saw A's
participation, and A's event surfaced on B's home (home = getUserEvents(currentUserId)).
Treat every identifier change as a fresh session: a ref-guarded useEffect([username])
clears publicDocs/protectedDocs, resetCaps(), resetRegistryCache(), then bumps the
read tick so the listing effect rebuilds the set bounded to the new identity.
Isolation stays per-document/emulated; the reset only drops cross-identity carryover.
Documented in knowledge_context-internals.
Validated (@data, real broker): after an A→B switch, B does not participate and
does not read A's participation; protected-isolation/read-filter/auth scenarios pass.
tsc + build green; lib untouched.

Consumer-side of the @ng-eventually/client fidelity pass, plus the identifier UX:
- Identity: the user types an IDENTIFIER at the access barrier (AccessGateScreen),
in the same act that opens the shared wallet — the separate 'pick a username'
screen (ConnexionScreen) is removed. The identifier is a technical id (a pseudo
in practice, not a Festipod username), normalized (trim, @-stripped, lowercased)
and persisted before the broker redirect, then handed to the SDK as the identity.
AccountContext keeps its API but its stored value is now this normalized id.
- Relationship/connections are app-owned: new src/shared/utils/connections.ts holds
the bilateral registry and maps each link to the SDK's directed grantRead(doc,
grantee); the lib no longer carries a connection concept. Rewired FestipodData
and the @data harness to it.
- Login removed: accounts use the SDK's IdentityStore (set/clear/get); no faux
login/logout framing in the SDK boundary.
Doctrine reconciled: app-security (knowledge_authentication flow, knowledge_trust-model
directed grants, decision_2026-07-06_identifier-at-access-barrier), data-layer
(knowledge_context-internals: stable id principal + single-seed), app-architecture
(knowledge_screens auth inventory), bdd-testing (caveat_wallet-bloat-hang).
App gates: tsc no new errors, build OK. @data path unaffected (harness bypasses the
gate and sets identity directly; login() is not on that path).

Multiple compounding defects kept the connected @data read at 0 entities:
- writeEntity/updateEntityField and registration helpers wrote into an explicit
GRAPH <plainNuri> named graph, invisible to the anchored default-graph read
(read-model.readDoc) after the read switched to per-doc anchored. Drop the
wrapper so writes land in the repo's default graph (matches the read).
- Seed entities are now owned by the CURRENT account, so protected seed docs
(user profiles) pass the per-document ReadCap gate and round-trip.
- Suppress the double seed (explicit loadTestData + 3s dev auto-seed) and add a
re-list signal so freshly-seeded protected docs enter the read set.
- @data step awaits the seed result and waits for events AND users > 0.
Documents the anchored-default-graph write pitfall in rule_document-per-entity.
Validated: connexion-nextgraph.feature @data = 4 scenarios / 13 steps green.
NB: the shared test wallet's private store bloats across runs and makes anchored
queries hang (>15s); a fresh .playwright-profile restores ~1.5s — durable wallet
hygiene is a follow-up.

- @data Before hook sets a UNIQUE virtual-wallet id (username) per scenario so each
scenario starts on a fresh, empty virtual wallet — isolation without touching the
physical wallet; "le portefeuille est vide" is now a fast check, not a full scan.
resetDataState / clearWallet fan-out dropped.
- bootstrapWallet now submits each seeded PUBLIC event to the discovery index
(mirrors the product createEvent), so a fresh virtual wallet can see seeded events
through discovery rather than as its own docs.
Note: @data still red — seeded/published events do not surface in the discovery
read (submit→readIndex round-trip against the real broker), and some publish steps
time out. The 75s ORM hang is gone; this is a distinct discovery-index integration
issue, still under diagnosis.
Read each by-need entity document with its own anchored query (bounded to the
current account's virtual wallet), never an anchorless scan of the physical shared
wallet. The 75s ORM hang stays gone; a non-empty PHYSICAL wallet now costs nothing
(never scanned). Removed the throwaway anchorless-union probe.
Known remaining (test-infra, not the product): the @data suite still times out
because THIS test account's VIRTUAL wallet is bloated (hundreds of docs
accumulated across this session's many runs) → per-doc reads are O(my docs), and
`clearWallet` still enumerates all accounts. Needs per-scenario test isolation
(fresh/small virtual wallet) + a virtual-wallet-scoped clear to validate green.

Replace the reactive-ORM per-entity fan-out read (which HUNG 75s: orm_start_graph
opened every scope graph and RepoNotFound on any fresh/unsynced doc aborted the
subscription) with the read model:
- readEntities.ts → lib readUnion: resolve the by-need doc set (my own scope docs
via listMyEntityDocs + public events via the discovery index — NOT all-accounts
fan-out), then ONE anchorless union sparql_query (GRAPH ?g, VALUES-pinned). Map
to app types. Re-query on a change signal (no reactive union query).
- countUserParticipations no longer fans out over all accounts (own docs only).
- await loadTestData in the seed step; deleted orphaned useShapeWithDefaults;
removed the old multistore-stopgap fan-out scenarios; added the read-model-probe.
- Doctrine: rule_document-per-entity read half + _overview rewritten to the union
model (write half unchanged).
Result: the 75s ORM hang is ELIMINATED (0 hangs; build/tsc/lib-93-tests green;
boundary clean). @data is NOT yet fully green: remaining failures are 90s step
timeouts in the test-harness broker data ops (clearWallet / runUnionProbe / seed)
this run — a harness/broker-op issue, not the read path. To finish separately.

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.

Festipod persists each entity as its own document (via the SDK), placed in its
scope. The document is the SDK's unit of sharing/permission, so per-document
isolation (private→owner, protected→owner+connections, public→all) is only
possible when each entity has its own document. Writing several entities into a
store-level document defeats per-scope isolation. Framed as SDK usage; the SDK
owns enforcement (app-security/knowledge_trust-model).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Enforce the boundary in code-comments and doctrine (adversarial-review cleanup):
- App comments in the data plane no longer narrate the SDK's internals: "emulated
curator"→"the inbox read", "fan-out"→"discovered", removed store-placement
reasoning and "polyfill/shim/mono-store" wording (FestipodDataContext,
registration, storeRegistry, ngSession, AccountContext, isolation, sharedWallet,
AccessGateScreen). Executable logic unchanged.
- Removed dangling references to the dissolved `nextgraph-platform` concept and
`brief_2026-06-15_shared-wallet-shim` from app code.
- knowledge_nextgraph-stack: dropped "mécanique d'émulation" from the boundary note.
- Settled and deleted all concept _debt.md (confirmatory; target leaves clean).
(Test-infra under workshop/ + generated features.ts still carry some simulation
vocabulary — parked as a separate below-SDK decision.)

Festipod now treats @ng-eventually/client as a finished NextGraph SDK: the app
decides only each entity's logical scope (events/PdR public, profiles/
participations protected, settings private) and calls the lib by scope. The old
mono-store default and the FESTIPOD_MULTISTORE path collapse into ONE scope path.
Removed every physical-store leak from the app data-plane (ngGraph, registration,
FestipodDataContext, NextGraphContext, useShapeWithDefaults): no more
did🆖${store_id} construction. The session is handed to the lib only at the
sanctioned injection point (ngSession/configureStoreRegistry). Product behavior
unchanged. @data 20/20; build + tsc clean.
(_debt.md included; the T03.e doctrine pass settles accumulated doc-debt.)

Enforce the project boundary: Festipod is written as if NextGraph were a mature,
finished SDK; @ng-eventually/client IS that SDK. NO current-NextGraph-state,
simulation, polyfill, shim, mono-store, store-id or broker-internal knowledge
remains in this repo — it now lives in the @ng-eventually/client repo.
- Dissolved the `nextgraph-platform` concept entirely (12 leaves — all
current-state/simulation, now in the lib's docs/). Rescued the genuine domain
parts into functional-domain/knowledge_data-scopes-and-discovery.md (which
entity → which scope; product-level discovery/notification intent), framed as
SDK usage with no mechanism.
- data-layer re-anchored to "how Festipod persists via the SDK": stripped
mono-store/private_store_id/RepoNotFound/DataCloneError/FESTIPOD_MULTISTORE.
Deleted the current-SDK compensation leaves (private-store-scope, multistore,
the 2026-03-17 ADRs, conditional-ng-init). Kept/reworded the domain + app
leaves; caveat_participation-deletion reduced to the domain contract.
- app-security reworded (isolation delegated to the SDK; app trusts it).
- AGENTS.md: dropped the nextgraph-platform row, reworded data-layer/
functional-domain/app-security, added the "Frontière SDK NextGraph" note.
- Fixed dangling [[links]]; concept lint clean (43 leaves).

- data-layer/caveat_multistore-is-multi-document (new): the recurring store vs
document confusion. Two axes — (A) which native store, (B) documents within a
store. FESTIPOD_MULTISTORE toggles axis B (multi-document), not multi-store.
Isolation (ReadCap) is per-document. As of T02.h the default path writes
shareable entities to the real protected store (axis A, step 1).
- rule_private-store-scope: rewritten — shareable entities now scope/@graph the
protected store; private anchors the shim/inbox + settings; "never did:ng:i"
kept. decision_2026-03-17 marked partially superseded.
- knowledge_stores-permissions: ⚠️ store↔document callout.
- knowledge_entities: MeetingPoint/Notification now persisted (not local-only).
- nextgraph-platform: decision_2026-06-17 records the emulated inbox; fork-inbox
brief marked short-circuited; discovery-model divergence (shipped fan-out vs
global-index target) flagged for confirmation.
- functional-domain/knowledge_roadmap, bdd-testing leaves updated. All doc-debt
settled; lint clean (60 leaves).

The "Se désinscrire" e2e wasn't obsolete: verified against the broker that
join reflects in the UI but leave does NOT — the button stays "✓ Je participe"
(>10s). DeepSignalSet.delete() does fire reactivity (touchIterable), so the
real cause is downstream: the deletion doesn't propagate / the item resurrects
via broker sync (the documented CRDT limitation).
- cycle-de-vie-evenement.feature: rewrite the désinscription scenario to be
self-contained (join → leave → "J'y serai" in one session, no cross-scenario
/ persistence dependency), and tag it @wip with an accurate comment.
- cucumber.json: add tags "not @wip" so known-incomplete scenarios document an
expectation without failing the suite (default run: 146 scenarios).
- docs: caveat_participation-deletion records the e2e finding (leave doesn't
reflect in the UI; delete fires reactivity but the item resurrects via sync);
knowledge_cucumber-setup documents @wip = excluded from the default run.

Captures the design worked out this session:
- decision: ng-eventually generic polyfill library (external repo) encapsulates all
multi-user compensation; @ng-eventually/client is SDK-identical, app depends only on it.
- decision: discovery via a single global index fed through its inbox (owned doc,
materialized) — no Group store; index owner = open question (singleton app, deferred).
- knowledge: NextGraph apps/services are mono-user with no global data (corrects the
earlier 'index service with its own wallet' model).
- reconciled shared-wallet-shim brief (per-entity docs, login flow, polyfill terminology),
authorization-matrix (no Group store), data-layer stack (ng-eventually indirection).
