+# Reliable Nostr DMs (Frontend)
+
+## Problem
+
+On the nostr-chat page, the DM sidebar could list conversations (kind-4 history existed on relays), but opening a conversation often showed **no messages**. Sending a DM also often failed to appear in the UI until a full refresh — and sometimes not even then.
+
+Logs from the REST2NOSTR proxy showed:
+
+- `GET /req/dms-…` returning multiple kind-4 events (inbox listing worked)
+- `POST /req/dm-{64-char-pubkey}-…` SSE subscriptions finishing immediately after relay `NOTICE` / close (conversation load failed)
+
+The channel-info URL (`kinds:[41]`) is **not** the DM fetch path; it only loads NIP-28 group channel metadata.
+
+## Root cause
+
+[NIP-01](https://nips.nostr.com/1) requires subscription IDs to be at most **64 characters**.
+
+The chat page built SSE subscription IDs like:
+
+```text
+dm-{64-char-peer-pubkey}-{timestamp}-{random}
+```
+
+That alone is already ~90 characters. The same pattern was used for group chat (`group-{channelId}-…`). Relays reject overlong `REQ` subscription IDs, so the SSE stream ended with no events.
+
+Other Nostr pages (`profile`, `user-feeds`, `global-feeds`, likes, follow list) already used short prefixes and were unaffected.
+
+Additionally:
+
+- Conversation history depended entirely on SSE `onEvent` (no GET bootstrap).
+- `selectedChannelIsDm` was inferred from `profiles[ch]`, so opening a DM before the profile finished loading could skip the DM subscription path.
+- Outbound messages were not shown until an SSE echo arrived.
+
+## Changes
+
+### Short opaque subscription IDs
+
+[`src/services/nostr-rest-client.js`](../src/services/nostr-rest-client.js) — `generateSubId(prefix)`:
+
+- Accepts a short semantic prefix (`dm`, `group`, `dm-notify`, `profile`, …).
+- Produces `{prefix}-{timestampBase36}-{random}` capped under a client-safe length.
+- Strips accidental embedded 64-char hex (pubkey / event id) if a caller still embeds one.
+
+Chat call sites now use `generateSubId('dm')` and `generateSubId('group')` instead of embedding hex IDs.
+
+### GET history + live-only SSE
+
+[`src/services/nostr-queries.js`](../src/services/nostr-queries.js):
+
+- `getDmMessages(myPub, peerPub)` — kind-4 conversation history via GET `/req`
+- `getChannelMessages(channelId)` — kind-42 group history via GET `/req`
+
+[`src/components/app-body/nostr-chat/index.js`](../src/components/app-body/nostr-chat/index.js):
+
+1. On channel select, load history with those helpers.
+2. Decrypt / render, then set `loadedMessages`.
+3. Open SSE with `limit: 0` (and `since` when history exists) for live updates only.
+
+### Chat reliability polish
+
+- DM vs group detection uses known DM / group channel membership (not only loaded profiles).
+- After a successful publish, the outbound message is shown immediately via `onMsgRead` (optimistic UI).
+- Subscription cleanup uses a single `subscription.close()` path (avoids double DELETE / abort noise).
+
+## Side effects
+
+| Area | Impact |
+|---|---|
+| Feeds / profile / likes / follow | Unchanged (already short sub-ids; still GET queries) |
+| Publish (`/event`) | Unchanged |
+| Group chat | Same reliability/efficiency pattern as DMs |
+| REST contract | Unchanged paths and response shapes |
