Fresh installs could sit on 'can't reach the servers' forever: the offers
cubit captured the transport once at build time, the shared connection only
retried on a connectivity CHANGE, and a silently-filtered relay could stall
the pool for minutes.
- SocialConnection: retry with backoff after a failed attempt while started
and not knowingly offline (injectable schedule for tests)
- OffersCubit: follow connection.sessions, re-attach the transport and re-run
the last discovery on (re)connect; announce drops via connectionEpoch
- market _init: record the wanted area on the cubit even while offline
- NostrOfferTransport.discoverPage: sort a copy (channel lists may be
unmodifiable)
Bound market memory and let large areas page instead of loading everything:
- DiscoveryQuery gains an until cursor; OfferTransport gains discoverPage()
(one-shot, EOSE-bounded, newest-first) alongside the existing live discover()
stream, which now accepts since so it only carries NEW offers going forward.
- NostrOfferTransport.discoverPage sorts by created_at desc and derives the
next cursor from the oldest event seen (not the oldest type-matched one, so
filtering never skips a page).
- OffersCubit: discover() fetches the first page + opens a since=now live sub;
loadNextPage() pages further back; the in-memory list is capped at 400
offers (each can carry a ~40KB inline photo thumbnail, so unbounded growth in
a busy area was a real OOM risk).
- market_screen: infinite scroll via a scroll-position trigger + footer
spinner, instead of a single unbounded ListView.
- Added discoverPage unit tests (commons_core) and cubit pagination tests
(first page/cursor, accumulation, cap, cross-page dedup).
Extract the market's query/type/category/organic filter chain into
SavedSearch.matchesFilters so live results and saved-search alerts can
never disagree. OffersState.visibleOffers now delegates to it.
The bilateral signed Plantaré's transport layer — the "formulario
bilateral firmado" from plantare-bilateral.md — as a new interface
alongside the other *Transport contracts, on the shared NostrConnection.
- PlantarePledge: the canonical, byte-stable core (debtor/creditor keys,
seed label, return kind, dates) plus the two Schnorr stubs. Any edit
changes the signing hash, so an accept is always over an immutable
payload.
- PlantareCrypto: BIP-340 signing/verification over SHA-256 of the core,
reusing the same primitive Nostr uses for events — a pubkey both
identifies a party and verifies their stub.
- PlantareTransport + NostrPlantareTransport: propose → accept →
counter-sign (and decline), private end-to-end. Rides the existing
NIP-17 gift wrap carrying a tagged JSON payload, so the relay sees only
ciphertext and an ephemeral author. Offline QR/NFC is the same payload
without a relay.
- Message transport skips Plantaré payloads on the shared kind-1059
channel (and vice-versa), so moves never surface as chat.
Tests: pure pledge/crypto + full handshake over a hermetic relay,
including no-leak and no-chat-bleed. commons_core 101/101 green.
Public name is now Tane (種, "seed"); Tanemaki (種まき, "to scatter seeds")
is kept only as etymology in the About screen and onboarding.
App not yet distributed, so format tokens rename cleanly with no migration:
backup extension .tanemaki→.tane, QR scheme tanemaki://→tane://, file
prefixes tane-*. Website link and species-catalog User-Agent →
tane.comunes.org. Android label capitalised to "Tane".
Identity/crypto constants already use org.comunes.tane (derivation, HKDF
backup, sync namespace, TANE1 recovery tag) — left untouched, so keys,
backups and sync are unaffected. Tests updated; analyze + full suite green.
Wallapop-style reputation primitive next to trust: Rating (1..5 stars +
optional comment), RatingTransport (rate/retract/ratingsOf/myRatingOf)
and a Nostr implementation on the shared channel. Addressable kind
30778, d = subject: one live rating per (rater, subject) — re-rating
replaces (a single author can never pile up reviews) and retracting
overwrites in place. Client-side dedupe mirrors NIP-01 replacement
order for relays that keep history.
The most foundational Block-2+ gap: the data model was built CRDT-ready
(HLC, tombstones, LWW, append-only Movement) and the import reconciler
proves the merge — but nothing replicated a device's inventory to your
OTHER devices. Only manual file backup/restore moved data between devices.
This lands the transport foundation in commons_core (seed-agnostic, on the
shared connection — the 'one connection, N interfaces' shape):
- SyncTransport: moves an opaque, encrypted snapshot blob between ONE
identity's own devices. The core carries bytes + does the crypto; the app
decides what the bytes are and how to merge them.
- NostrSyncTransport: NIP-78 app-data (kind 30078, addressable/replaceable
per device via the d-tag), content NIP-44-encrypted TO SELF, discovery
filtered to your own author key. Each device keeps one replaceable record.
Tests (MiniRelay, pure Dart): a snapshot replicates to the identity's other
device; the relay only ever sees ciphertext; another identity neither
receives nor could decrypt; re-push replaces; two devices keep their own.
Confirms the open-decisions §D.4 guarantee (sync leaks neither the key nor
plaintext). NEXT slice (app): a SyncService that serializes the inventory
(reusing ExportImportService), pushes on mutation, and runs the existing
idempotent importInventory on receive; a stable per-install device id;
wire sync into SocialSession.
Slice 4 of Block 2. The pure rule was already parameterised; this adds the
policy, cold-start and UI around it.
- commons_core: WotParams (sigQty/stepMax/sigValidity, Duniter defaults) +
WebOfTrust.membersWith; npubToHex helper (NIP-19 decode) for adding roots.
- WotSettings (keystore): the active parameters, configurable — a young
network loosens them and tightens as it grows, as Ğ1 did. Defaults Duniter.
- TrustReferents: the bootstrap 'seeds' membership is measured from — a
bundled asset (empty until real founders are curated, no invented keys)
unioned with referents the user adds by npub/QR. Honest cold-start.
- TrustCubit: computes the full membership verdict against referents+params
alongside the personal circle, and exposes a TrustTier (networkMember >
inYourCircle > vouched > unknown). Certifications issued with the active
validity (they expire and renew, Duniter rule).
- UI: chat trust badge by tier; a 'Network of trust' screen (manage roots +
advanced params) reached from the profile. i18n en/es/pt/ast.
Tests: WotParams/membersWith, npubToHex, TrustReferents, WotSettings, and
TrustCubit tiers/membership. Resolves the WoT-parameters decision
(open-decisions §B). Trust net stays empty/undetermined until seeded — by
design; users bootstrap their own roots.
The vecino/market view had three gaps:
- Publishing inventory duplicated the listing. discover() appended every
offer the relay streamed, but relays legitimately resend an addressable
NIP-99 event (stored copy + live echo on publish). Merge by
(authorPubkeyHex, id) so each offer appears once; two authors reusing a
lot id stay distinct.
- No product detail. Tapping a card jumped straight to chat. Add a
read-only "product page" (MarketOfferDetailScreen) with title, mode,
category, eco badge, coarse location, price, a "Shared by" seller
section (profile fetched by pubkey) and the message button. Reached via
a new /market/offer route; cards are now fully tappable. Shows only what
the network already carries — no photos/description added to the wire.
- No filters. Add a filter bar (type, category, eco) mirroring inventory,
each chip group shown only when a discovered offer can match it. To make
the eco filter real, publish the organic flag on the wire: Offer.isOrganic
-> NIP-99 'organic' tag -> OfferMapper -> ShareableLot.
Tests: commons_core organic round-trip; app-side dedup, two-author
separation, filter logic, mapper passthrough; detail-screen widget tests.
i18n keys added to en/es/pt/ast and slang regenerated.
The optional Ğ1 (free currency) integration, per g1-integration.md.
- Profile: an optional 'Ğ1 address' field, persisted locally and published in
your NIP-01 kind:0 metadata (separate from the Nostr key).
- commons_core: UserProfile/ProfileTransport carry a 'g1' field (round-trip
tested).
- Chat: when the peer published a Ğ1 address, a 'Pay in Ğ1' app-bar action opens
their wallet (url_launcher) so value moves in the wallet, not the app — copies
the address as a fallback. No payment rails in-app (sharing-model §4.3).
NOTE (vjrj): the wallet deep-link uses the Cesium web wallet as a universal
fallback; swap the URI in chat_screen._payG1 for the Ğ1nkgo/Ğecko scheme you
prefer. Analyzer clean (both packages); profile transport test covers g1.
Drawer 'Profile' is now live.
- commons_core: ProfileTransport + UserProfile + NostrProfileTransport (kind:0
publish/fetch), exposed as SocialSession.profile. Round-trip tested against the
in-process relay (fast dart test).
- app: ProfileStore (local name/about, keystore) + ProfileScreen — shows your
shareable npub with copy, edits display name + 'about', saves locally and (when
online) publishes kind:0 so peers can recognise you instead of a raw key.
- Drawer 'Profile' -> /profile (gated like Market/Chat).
- i18n en/es/pt. ProfileStore + profile transport covered by plain/dart tests.
Analyzer clean (both packages).
Relay-strategy hardening (network-trust §3): don't hang on one relay.
- NostrChannel interface: what the transports need (sign, publish, subscribe,
reqOnce). Implemented by NostrConnection (single relay) and the new RelayPool.
- RelayPool: connects to all configured relays (skips unreachable ones, throws
only when none are reachable), publishes to every live relay (accepted if any
accepts), merges discovery deduped by event id, and survives a relay dropping.
- Transports now depend on NostrChannel, not a concrete connection.
- SocialService.openSession takes ALL configured relays (was relays.first);
createOffersCubit passes the whole list.
commons_core 63 tests green (3 new pool tests over two in-process relays);
app_seeds social/market 18 green.
Pure Dart lat/lon -> low-precision geohash (public-domain algorithm), the piece
the coarse-area capture needs so people never type a code. Precision-controlled
(5 chars ~ ±2.4 km). Tested against the canonical u4pruydqqvj vector + prefix/
proximity properties. 5 tests green.
Second production slice: the concrete Nostr backend on the shared connection,
using the vetted nostr package's crypto (NIP-44 spec-vector tested, gift wrap).
- NostrConnection: one dart:io WebSocket + identity + EVENT/OK, REQ/EOSE via
the library's Event/Filter/Request. Pure Dart, no Flutter.
- NostrOfferTransport (NIP-99 kind 30402) + Nip99Codec: geohash coarsened to a
NIP-52 prefix ladder on the wire; Offer stays inventory/location-agnostic.
- NostrMessageTransport (NIP-17): send/inbox via the library's DirectMessage
gift-wrap onion.
- NostrTrustTransport (custom addressable kind 30777): certify/revoke/discover.
- MiniRelay test support + integration tests: offers, messaging (metadata
privacy), WoT membership + revoke, and trust-filters-offers — all over ONE
shared connection, hermetic in-process relay.
Renamed the core offer lifecycle enum OfferStatus -> OfferLifecycle to avoid
colliding with app_seeds' sharing-intent OfferStatus (no Block 1 code touched;
app_seeds analyzes clean, 0 errors). commons_core: 55 tests green.
