Edits across all 13 EGGs to remove implementer guesswork. After this an
implementer can build a listener and speaker without reading our source.
README:
- Conventions section: hex casing rule (lowercase, 64 chars, no 0x),
NIP-01 foundations, `a`-tag form, created_at tie-break, JSON / time.
- Joining sequence: numbered end-to-end walkthrough from `kind:30312`
to first audio frame, referencing each EGG.
EGG-01 (room event):
- `relays` tag is one tag with multiple values (not multi-tag).
- `service` URL trailing-slash normalization.
- `private` status: gate is implementation-defined, not "render as open".
- `d`-tag charset locked to [A-Za-z0-9._-] so it interpolates safely
into the moq-auth namespace.
- Relay-discovery rule: publish to `relays` tag ∪ NIP-65 outbox.
- Tie-break on identical created_at via smallest event id.
EGG-02 (auth):
- JWT signing pinned: ES256 over P-256, JWKS at /.well-known/jwks.json,
5-minute relay cache.
- NIP-98 tags pinned: u / method / payload, base64 RFC 4648 standard
(not base64url).
- Error taxonomy: full HTTP status + `error` slug table for /auth, plus
WebTransport CONNECT 200/401/403/404 table.
EGG-03 (audio):
- Pin moq-lite Lite-03 to kixelated/moq-rs `rs/moq-lite/src/lite/`.
- One Opus packet per moq Frame (no container, no timestamp).
- Pubkey hex casing reaffirmed at the suffix / broadcast slots.
- AnnouncePlease prefix="" for speaker discovery.
- Mute = stop publishing (not silence frames, not Announce Ended).
- Mid-stream join: discard pre-skip per RFC 7845.
EGG-04 (presence):
- Heartbeat jitter ±5 s required (anti-thundering-herd).
- "0"/"1" are strings, not booleans.
- Single-room rule via replaceable-event semantics.
EGG-05 (chat): 8 KB suggested, 64 KB hard cap, 3 msg/s render rate.
EGG-06 (reactions): 30s window measured against created_at, drop-on-arrival
if already stale.
EGG-07 (moderation): replay protection — dedupe kicks by id within 120 s.
EGG-08 (scheduling): planned rooms MUST 403 at the auth sidecar.
EGG-10 (theming): bg image caps (1 MB / 4096 px soft, 8 MB / 8192 px hard).
Deferred (per review): EGG-00 (Conventions as a standalone spec), EGG-13
(capability advertisement), EGG-14 (discovery), test vectors corpus.
The "Conventions" section in README covers EGG-00's most urgent content
inline.

# EGG-06: Reactions (`kind:7`)
|
|
|
|
`status: draft`
|
|
`requires: EGG-01`
|
|
`category: optional`
|
|
|
|
## Summary
|
|
|
|
Audience-side ephemeral feedback (👏 ❤️ 🎉 ...) is carried on standard
|
|
NIP-25 `kind:7` reaction events, scoped to the room via an `a`-tag.
|
|
Clients render these as a short-lived floating overlay over the
|
|
participant grid.
|
|
|
|
A reaction is NOT durable state. Clients SHOULD NOT page through
|
|
historical reactions; only the recent window matters.
|
|
|
|
## Wire format
|
|
|
|
```json
|
|
{
|
|
"kind": 7,
|
|
"pubkey": "<reactor pubkey hex>",
|
|
"tags": [
|
|
["a", "30312:<host pubkey hex>:<room d>", "<relay hint>"],
|
|
["p", "<target pubkey hex>"]?,
|
|
["emoji", "<shortcode>", "<image url>"]?
|
|
],
|
|
"content": "<emoji glyph or :shortcode:>",
|
|
...
|
|
}
|
|
```
|
|
|
|
`content` carries the reaction itself. Standard Unicode emoji glyphs are
|
|
used directly. Custom emoji follow NIP-30: `content = ":shortcode:"` with
|
|
a sibling `["emoji", shortcode, url]` tag.
|
|
|
|
A reaction MAY include a `["p", target]` tag scoping the reaction to a
|
|
specific speaker (renders over their avatar). With no `p` tag, the reaction
|
|
is room-wide (renders centered on the room canvas).
|
|
|
|
## Behavior
|
|
|
|
1. Reactors MUST emit `kind:7` events with at least one `a`-tag matching
|
|
EGG-01 and a non-empty `content` field.
|
|
2. Receivers MUST apply a 30-second sliding window measured against the
|
|
reaction's `created_at`: a reaction is rendered from the moment it is
|
|
observed until `created_at + 30 s` (wall-clock unix seconds), then
|
|
dropped from the floating overlay. A reaction that arrives already
|
|
older than 30 s MUST be dropped on receipt without ever being shown.
|
|
3. Receivers SHOULD throttle their reaction-overlay updates to at most 4 Hz
|
|
(250 ms minimum between repaints). At ~30 reactions per second a naive
|
|
recomposition can starve the audio decoder.
|
|
4. Receivers MUST tolerate unknown `content` values (e.g. a Unicode glyph
|
|
without a font fallback) by falling back to a generic indicator rather
|
|
than dropping the reaction.
|
|
5. Receivers MUST NOT auto-fetch the `["emoji", _, url]` image at the
|
|
moment of receipt — that opens an animated-emoji-driven DDoS vector.
|
|
Image fetch SHOULD be batched and rate-limited.
|
|
6. A reactor MAY include the same `a`-tagged reaction more than once
|
|
(e.g. spamming claps). Receivers MUST NOT de-duplicate by content
|
|
alone; events with different ids are always distinct.
|
|
|
|
## Example
|
|
|
|
A clap reaction targeted at a speaker:
|
|
|
|
```json
|
|
{
|
|
"kind": 7,
|
|
"pubkey": "ghi...audience",
|
|
"created_at": 1714003220,
|
|
"tags": [
|
|
["a", "30312:abchost:office-hours-2026-04"],
|
|
["p", "def...co"]
|
|
],
|
|
"content": "👏",
|
|
"id": "...",
|
|
"sig": "..."
|
|
}
|
|
```
|
|
|
|
A custom-emoji reaction (NIP-30):
|
|
|
|
```json
|
|
{
|
|
"kind": 7,
|
|
"pubkey": "ghi...audience",
|
|
"created_at": 1714003221,
|
|
"tags": [
|
|
["a", "30312:abchost:office-hours-2026-04"],
|
|
["emoji", "amethyst", "https://example/amethyst.png"]
|
|
],
|
|
"content": ":amethyst:",
|
|
"id": "...",
|
|
"sig": "..."
|
|
}
|
|
```
|
|
|
|
## Compatibility
|
|
|
|
EGG-06 is independent from EGG-05 (chat). A peer MAY implement either,
|
|
both, or neither without affecting interop on EGG-01 through EGG-04.
|
|
|
|
Future EGGs MAY introduce paid reactions (`kind:9735` zap receipts at the
|
|
same `a`-tag). Implementers SHOULD be prepared to source the reaction
|
|
overlay from both `kind:7` and `kind:9735` streams.
