The sidebar card badged 'Private chat - On' while the MLS tab said 'not created
yet', and led with external apps. Rewrote CrewCoordinatorCard to show two
explicit rows (Chat = NIP-17 always on; Private chat = MLS with real status) and
make the in-app chat the primary CTA (?tab=mls); demoted Cordn web / Staircase
under 'Open in another app'. Panel now gives join feedback + an admin invite
hint. Adds CORDN_UX_AUDIT.md (findings, terminology model, deferred items).
Crews can carry a Cordn group ref (['cordn', <cordn1-ref-or-url>] -> SkateCrew.cordnGroup): CrewForm gains a 'Cordn group' field and CrewCoordinatorCard shows an 'Open crew chat' (cordn.net/chat/<ref>) + 'Copy for Staircase' row. Verified a real ContextVM client (@contextvm/sdk) connects + lists tools against our self-hosted coordinator.
Relabel the cordn.net add-link accurately as 'Cordn (web)' (real MLS in the browser) and add a 'Copy for Staircase' button that copies the coordinator nprofile for the native app. Our coordinator by default; a BYO coordinator's add-link when it has a pubkey.
CrewCoordinatorCard now offers a StaircaseLink in both branches: our coordinator (SKATESPOTS_COORDINATOR add-link) when a crew has none, and the crew's own coordinator add-link when it has a pubkey (falls back to the Cordn home otherwise). Lets crews jump to real MLS chat in the native Cordn client.
The transport treats a crew's wss:// coordinator URL AS A RELAY, and an https://
one falls back to the public wss://relay.contextvm.org. So 'nothing crew-specific
hits a public relay' was false for https coordinators — it put ciphertext +
metadata (crew coord, timing) on a public relay.
- CrewCoordinatorCard: shows the actual relay in use, and states honestly
whether it's the crew's own or the shared public one.
- CrewForm: the coordinator field now says a wss:// endpoint is the crew's own
relay and an https:// one routes over the shared public relay.
- AGENTS.md: record the relay-vs-coordinator transport reality so this isn't
re-derived (and Cordn RPC is not called).
Decision (per Marmot/Concord/Cordn analysis): a semi-public, socially-verified
skate crew fits Concord-style shared-key chat, not MLS. The built-in NIP-17
giftwrap group chat is already the right answer and works with zero setup — so
stop implying a coordinator is required and stop over-claiming MLS guarantees
the code doesn't yet provide.
- CrewCoordinatorCard: default state now reassures that private E2E chat is
already ON (no setup) for everyone, instead of prompting founders to "set up a
coordinator". Founders get a small, honestly-labeled advanced link to the
self-hosted Cordn option. Fixed the "E2E · MLS / forward secrecy" badge — the
coordinator path is NIP-44 group encryption routed over ContextVM, not an MLS
ratchet.
- CrewForm: the coordinator field is now clearly "experimental · self-host",
states you don't need it, and links to the Cordn repo.
- NIP.md: reworded the crew-chat section + tag/profile descriptions to match the
honest crypto seam (NIP-44 group today; MLS a future upgrade), so docs no
longer claim forward secrecy that isn't shipped.

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.

- Extend SkateCrew with `sponsorRef` (sponsoring shop, NIP-15 stall coord) and
`coordinator` (Cordn/MLS encrypted-chat Delivery Service pointer), plus parser.
- CrewSponsorBanner: "Sponsored by [Shop]" banner that resolves and links the
backing shop; renders nothing if the shop can't be resolved.
- CrewCoordinatorCard: surfaces the crew's private-chat coordinator (E2E · MLS),
explains what the coordinator can/can't see, shows the operator, and prompts
the leader to set one up when absent — the UI foundation for Cordn chat.
- Wire the sponsor banner (under hero) and coordinator card (sidebar) into
CrewDetailPage.
- CrewForm: add "Sponsored by" and "Private Chat Coordinator" inputs with
validation; publish `sponsor` and `coordinator` tags.
- NIP.md: document the `sponsor` and `coordinator` tags, the structured invite
kind 36229 (with accept/decline flow), and the Cordn/MLS private-chat model
and why it's the chosen fit for crews.
