-# Web of Trust — implementation plan
-
-A plan for scoring strangers by the user's follow graph, based on how Amethyst
-implements web of trust. The goal is to make the screening dialog and the chat
-requests list more useful: "3 of your contacts follow this person" instead of a
-bare npub, and a way to let trusted strangers skip screening.
-
-## 1. How Amethyst does it
-
-Amethyst (vitorpamplona/amethyst) has two independent WoT layers:
-
-**Layer 1 — follow-graph score (`WoTService`)**, in
-`commons/src/commonMain/kotlin/com/vitorpamplona/amethyst/commons/wot/WoTService.kt`:
-
-- For every pubkey `X`, the score is the number of people the user follows who
-  also follow `X` (friends-of-friends, computed only from kind 3 contact lists).
-- The user's own follow set and each followed user's kind 3 feed the graph; the
-  service keeps a reverse index `target -> {followers}` and derives scores from
-  set sizes.
-- Purely in memory, rebuilt on start; a single writer coroutine serializes
-  updates via an op channel and diffs each follower's list on republish, so a
-  changed kind 3 only touches the entries it added/removed.
-- Guardrails: WoT is disabled when the user follows more than `MAX_FOLLOWS`
-  (2000) accounts, and each ingested contact list is capped
-  (`MAX_FOLLOWS_PER_EVENT`, 5000) to bound hostile publishers.
-- A `ready` flag (set on first EOSE) tells the UI when scores are usable.
-- Consumers sort people follows-first, then by score (`PeopleOrder.kt`) and show
-  a desktop badge.
-
-**Layer 2 — NIP-85 trust-provider index**, in
-`commons/.../wot/network/` and `quartz/.../nip85TrustedAssertions/users/index/`:
-
-- The user names a "trust provider" (e.g. Brainstorm/GrapeRank) in a kind 10040
-  event; the provider publishes a signed rank card (kind 30382) for every member
-  of the user's extended network (~150–300k events).
-- The client downloads the whole set once, verifies every signature, and stores
-  a compact binary index (~6 MB: 128-bit key prefixes + rank/hops/followers
-  arrays) with cursor-based incremental sync (NIP-45 COUNT + NIP-77 negentropy).
-- The gate is `accepted(pk) = pk == me || pk in follows || rank(pk) >= minScore`
-  and it drives the DM Known/New split, the "Curated" notification filter, push
-  filtering, and collapsing out-of-network replies. Exemptions live in one
-  predicate (`TrustVerdicts.kt` / `CuratedTrustFilter.kt`) so in-app and push
-  can't drift: zaps always pass, chats follow the DM rule, everything else is
-  gated on network membership.
-
-### What we take, what we skip
-
-| Amethyst piece | Take? |
-|---|---|
-| Friends-of-friends score, reverse index, diffing, caps, ready flag | Yes — this is the whole feature for coop |
-| Follows-first ordering helper | Only if we ever list non-contacts; not needed now |
-| NIP-85 provider onboarding, kind 30382 index, negentropy sync, binary files | No — massive sync + storage complexity for a DM client |
-| One shared exemption predicate per surface | Yes as a principle: gate requests in one place |
-
-Layer 2 exists because Amethyst gates a 300k-user social graph. Coop gates
-incoming DMs; the follow graph (one hop of contact lists) is enough signal and
-needs no new events, relays, or storage formats.
-
-## 2. Design: `WebOfTrust` in the `person` crate
-
-One new logical component, one new file: `crates/person/src/wot.rs`, re-exported
-from `crates/person/src/lib.rs` and initialized in `person::init` as a global
-entity, exactly like `PersonRegistry`.
-
-### State
-
-```rust
-pub struct WebOfTrust {
-    /// The signed-in user's contacts (latest kind 3)
-    follows: HashSet<PublicKey>,
-    /// The current user, excluded from credit
-    self_key: Option<PublicKey>,
-    /// Per-follower cached follow set, for diffing on republish
-    lists: HashMap<PublicKey, HashSet<PublicKey>>,
-    /// Reverse index: target -> contacts who follow them
-    reverse: HashMap<PublicKey, HashSet<PublicKey>>,
-    /// Disabled when the follow set exceeds MAX_FOLLOWS
-    disabled: bool,
-    ready: bool,
-    tasks, subscriptions, ...
-}
-```
-
-API (all reads are plain methods; writes go through the entity):
-
-```rust
-pub fn score(&self, key: &PublicKey) -> usize        // reverse[key].len()
-pub fn is_in_network(&self, key: &PublicKey) -> bool // follows || score >= 1
-pub fn mutuals(&self, key: &PublicKey) -> Vec<PublicKey> // who vouches, for the dialog
-pub fn is_ready(&self) -> bool
-pub fn is_disabled(&self) -> bool
-```
-
-Events: `WoTEvent::Updated` and `WoTEvent::Ready`, emitted after hydration and
-on every graph change; consumers subscribe like they do to `PersonRegistry`.
-
-### Data flow — reuses the existing pattern end to end
-
-Same shape as `PersonRegistry::new` (background listener -> flume channel ->
-entity update -> `cx.emit`):
-
-1. **Hydrate from the local database** on creation and on
-   `StateEvent::SignerChanged`:
-   - own kind 3 (newest event, `limit(1)` like `Directory::track` and
-     `query_chat_rooms` do) -> `follows`;
-   - applied immediately so the dialog has data before the relays respond.
-2. **Stay fresh with NIP-77** (`WebOfTrust::sync`, no persistent subscription):
-   - `client.sync(Filter::new().kind(Kind::ContactList).authors(follows + self))`
-     reconciles with every relay in the pool and downloads only the contact
-     lists the local database is missing (negentropy items come from the
-     database, direction is down-only);
-   - after each reconcile, the newest stored list per covered author is applied
-     to the graph and a `Ready`/`Updated` event marks what changed;
-   - triggers: hydrate, a 15-minute timer (Amethyst's D10 cadence), and a
-     follow-set change; when a reconcile grows the follow set (fresh install),
-     it re-syncs once more to cover the new authors.
-3. **Rules ported from `WoTService`**:
-   - exclude the follower and `self_key` from every ingested list;
-   - on follow-set change, un-credit removed followers from the reverse index;
-   - `MAX_FOLLOWS = 2000` disables the service (clear state, emit ready);
-   - `MAX_TAGS_PER_LIST = 5000` caps one follower's ingested list;
-   - reset everything on sign-out / account switch.
-
-No persistence: the graph rebuilds from the LMDB cache on every start, the same
-way `ChatRegistry` rebuilds rooms. No new relay events, no settings file, no new
-dependencies. Relays without NIP-77 fail their reconcile (logged); the graph
-then reflects whatever the database already holds.
-
-## 3. Consumers (in order)
-
-### Phase 1 — screening dialog (`crates/workspace/src/dialogs/screening.rs`)
-
-Status: **implemented**. The `WebOfTrust` registry lives in `crates/person/src/wot.rs` and
-is initialized in `person::init`.
-
-Replace `check_wot`'s database query (which only sees contact lists that happen
-to be cached, so "mutual contacts" is usually empty) with the registry:
-
-- `mutual_contacts = wot.mutuals(&public_key)` — the people **the user follows**
-  who follow the stranger, which is the correct WoT semantic and matches
-  Amethyst's score.
-- The existing "Mutual contacts" dialog keeps working unchanged: it already
-  renders a `Vec<PublicKey>` through a `Directory`.
-- When `wot.is_disabled()` or not ready, fall back to the current query so the
-  dialog degrades to today's behavior.
-
-### Phase 2 — requests list badge
-
-Status: **partially implemented**. Request rooms whose members are all outside
-the web of trust show a `SPAM` badge in the sidebar
-(`Room::is_spam` + `WebOfTrust::is_outside`, rendered in
-`crates/workspace/src/sidebar/rows.rs`; the sidebar subscribes to `WoTEvent` so
-badges update when the graph loads). The profile dialog shows the score as a
-"Web of Trust" field (`crates/workspace/src/dialogs/profile.rs`, other users
-only). The mutual-count caption below is still open and will follow a
-different flow.
-
-Where request rooms are rendered, show the mutual count for the sender:
-
-- `crates/workspace/src/sidebar/inbox.rs` (`requests_rows`) and
-  `crates/workspace/src/panels/greeter.rs` (`load`): one caption
-  `"N mutual contacts"` under the request preview, via the room's other member.
-- Subscribe to `WoTEvent::Updated` where `PersonEvent` is already subscribed so
-  rows re-render when the graph changes.
-
-### Phase 3 — opt-in auto-trust (behind a setting)
-
-Status: **implemented** (Phase 2 skipped for now; it will follow a different
-flow).
-
-The payoff: strangers vouched for by the user's contacts can skip screening.
-
-- `pub wot_auto_trust: bool` in `setting_accessors!` in
-  `crates/settings/src/lib.rs` (enabled out of the box: `Default` is `true` and
-  a `#[serde(default = "default_true")]` fallback covers settings files saved
-  before the field existed) and a "Web of trust" toggle in
-  the preferences screen (`crates/workspace/src/dialogs/settings.rs`).
-- The rule lives in one predicate — `Room::auto_trusted(me, cx)` in
-  `crates/chat/src/room.rs`: the setting is on and every member other than the
-  current user is inside the web of trust (`is_in_network`, so followed
-  senders always pass and strangers need at least one mutual contact).
-  It's applied at every point a room's kind is decided so the states can't
-  drift: `ChatRegistry::add_room` (incoming first message),
-  `ChatRegistry::new_message` (live promotion next to the existing
-  I-sent-it rule), and `ChatRegistry::extend_rooms` (rooms loaded from the
-  database, so the split survives a restart).
-
-Deliberately not planned: sorting contacts (the new-chat dialog lists only
-follows already), notification feeds (coop has none), muting/spam scoring.
-
-## 4. Non-goals
-
-- NIP-85 trust providers (kind 10040/30382), Brainstorm onboarding, rank
-  thresholds — revisit only if coop ever needs a network-scale gate.
-- Persisting the graph or multi-hop (3+) scores — kind 3s are one LMDB query
-  away on restart, and negentropy keeps them current.
-
-## 5. Testing
-
-- Unit tests for the pure graph logic in `wot.rs` (no `cx` needed): seeding,
-  per-follower diffing, follow-set removal un-crediting, self/follower
-  exclusion, both caps and the disabled transition.
-- One GPUI test for hydration ordering (newest kind 3 wins) using
-  `TestAppContext`; use `cx.background_executor().timer(...)` for any waits per
-  the project guidelines.
