Sending to a crew fired every recipient's gift wrap in parallel (Promise.all),
and the sealed-relay crew chat encrypted to the whole roster in parallel. Amber
is a single foreground activity: concurrent nostrsigner: intents mean only one is
answered and the rest sit until the 60s native timeout rejects with 'Amber didn't
respond'. Both paths now go sequentially for an interactive signer (parallel kept
for silent signers). Also corrected the approval hint (2 per member: encrypt +
sign, not 1 per recipient).
- DirectMessagesPage gains a 'Crews' block listing the viewer's crews with an
Open/Set-up badge (from one local IndexedDB read via useCordnGroupGids),
linking into /crew/<pk>/<id>?tab=mls.
- Crew page tabs are now URL-addressable (?tab=events|chat|mls); an explicit
param wins over the auto-default. useUserCrews + cordnGroupGids added.
- Crew page defaults to the Private-chat (MLS) tab when this device already has
the group (useCordnGroupExists reads the IndexedDB snapshot — local only, no
signer prompt); a manual tab click always wins.
- Founder/admin banner ('Set up') points at the tab when the crew has no group.
- Bump 1.6.0 -> 1.6.1 and add release notes for everything since 1.6.0 (private
crew chat/MLS, self-hosted relay + media, marketplace close-the-deal, trust
controls, map/weather, Clothing Designer, UI fixes).
- scripts/cordn-browser-probe.mjs: headless-Chromium proof that the built
native chunk runs in a real browser — imports the chunk, runs a session
against the coordinator (publish kp, create group, send), then reopens from
the Dexie/IndexedDB store. Not part of npm test (needs network + Chromium).
- Group ref: the panel shows/copies the group's cordn1... ref
(encodeGroupRef from the crew coordinate + coordinator), so it can be opened
in Staircase/cordn-web. Computed in the hook via the lazy native import.
- Images: attach button uploads to Blossom (useUploadFile) and sends the URL
inside the encrypted MLS envelope (['image', url]); CordnChatMessage.imageUrl
+ ImageWithFallback rendering. Covered by the live test.
- Unread badge deliberately not built (needs a background signed request).
npm test + smoke + browser probe + 3 live scenarios all pass.
Milestone 2 for the native Cordn client.
- Session now runs on the viewer's own signer (NIP-07/Amber/nsec) instead of a
raw key, so the Cordn identity is the user's pubkey. Added idbStore.ts
(Dexie 'SkateSpotsCordnDB', one snapshot per account) so MLS state survives a
reload, plus membership delivery: requestJoin / fetchJoinRequests /
fetchWelcomes / acceptWelcome / addMemberByIdentifier, and addMember now also
stores the Welcome on the coordinator for the target.
- useCordnNative owns the session lifecycle and lazy-imports the native module,
keeping @contextvm/sdk + ts-mls in a separate ~678 kB async chunk (entry
bundle unchanged at 1.9 MB).
- CordnNativePanel: a third 'Private chat' tab on the crew page — founder/admin
create the group and approve join requests; members ask to join and check for
an invite; live message list + composer (polling only for silent signers).
- Strings in i18n/legacy/cordnUi.ts (en/es).
Verified live against our coordinator with a new scenario
(join-request -> approve -> welcome) plus the existing two; npm test + smoke
pass. Not yet exercised in a real browser (browser tooling was offline this
session) — the dynamic-import failure path degrades to an inline error.
Add src/lib/cordn/native/ — a browser-safe Cordn client doing real RFC 9420
MLS over a ContextVM coordinator, mirroring Cordn's wire contract (reimplemented,
not copied from @cordn/cli).
- mls.ts: identity, key packages, group create/add/join, application messages,
the ChaCha20-Poly1305 coordinator wrapper, causal prev tags.
- coordinator.ts: ContextVM/MCP-over-Nostr client on @contextvm/sdk, validated
with @cordn/core schemas.
- session.ts: CordnSession (key packages, createGroup, addMember->Welcome,
joinGroup, send, fetch) with persistence behind an injectable CordnStore
(MemoryCordnStore today; IndexedDB adapter TODO).
- Verified end-to-end against our own coordinator: a two-member round trip
(CORDN_LIVE=1 vitest run native.live.test.ts) — create, add, join, and
bidirectional encrypted messages with proven senders.
Deps: @cordn/core, @contextvm/mcp-sdk, @noble/ciphers pinned 2.2.0 (fixes the
previously invalid tree: ts-mls wants 2.2.0, a stale root copy was 0.5.3).
src/test/setup.ts is now guarded for node-environment test files. Not wired to
any UI yet; nothing imports the module, so the web bundle is unchanged.
Close the metadata gap: the outer kind-4497 envelope was signed with the
sender's real key, so a coordinator/relay could see exactly who was talking.
- buildEnvelope now signs each envelope with a fresh ephemeral key (NIP-59
style) — the coordinator never learns the sender.
- Authorship moves inside the ciphertext: a new v2 sealed payload
(`nip44-group-v2`) carries a fully-signed inner author-proof event (kind 4498)
bound to the crew via an `a` tag. openGroupMessage verifies the signature,
author, content match, and group binding — so authorship stays unforgeable and
a proof can't be replayed into another crew.
- Transport trusts the verified v2 proof and surfaces the real sender; legacy
v1 envelopes remain readable (outer-key binding) for back-compat.
- NIP.md updated with the v2 format + an honest note on the residual
verbatim-replay caveat (full replay/forward-secrecy hardening lands with MLS).
Scope decision: kept to crew chat only. Regular 1:1/group DMs already use NIP-17
gift wrap (ephemeral keys, sealed per recipient) and have no coordinator, so
they need no change and stay idiot-proof.

The crew coordinator is no longer just a pointer — when a crew configures one,
the Chat tab runs through it for real.
- src/lib/cordn: clean transport/crypto split so an MLS (ts-mls) upgrade is a
drop-in swap of the crypto layer only.
- types.ts: CordnMessage/CordnEndpoint + envelope kind 4497 + app tag.
- crypto.ts: sealGroupMessage/openGroupMessage — real NIP-44 group encryption
(per-recipient sealing), the exact seam MLS encrypt-to-epoch slots into.
- client.ts: buildEnvelope/publishEnvelope/fetchGroupMessages with per-group
cursor ordering and ciphertext→author sender binding (anti-spoof).
- endpoint.ts: resolve a crew's `coordinator` to a usable relay endpoint
(wss/ws direct; https falls back to the ContextVM relay).
- useCordnChat: fetch-then-poll hook mirroring the NIP-17 chat API.
- CrewChat: uses Cordn when the crew has a coordinator, NIP-17 fallback
otherwise; header badge shows the active transport (Cordn vs Private).
- CrewCoordinatorCard: reflects that private chat is live.
- NIP.md: document envelope kind 4497, delivery (fetch-then-poll + cursors),
the nip44-group sealed content, and the honest crypto→MLS seam.
Real encryption, real coordinator routing, non-breaking (fallback intact),
with the MLS ratchet as a clearly-marked next step.
