Each module has SUMMARY.md and NATS.md (who sends/receives, subject addresses, payload). Tests: splitter 3, worm 3, aggregator 2. Forgejo repos pushed separately; this commit keeps them in the monorepo.

# Modules and NATS message contracts
|
||
|
||
Master map of every service in the Zapier ↔ middleware ↔ chain ↔ WORM-archive path.
|
||
|
||
Zapier cloud **never** connects to NATS. Only middleware workers and archives do.
|
||
|
||
## Who talks to whom (HTTPS vs NATS)
|
||
|
||
```text
|
||
[Zapier Platform app] HTTPS [zappier-edge] HTTPS [middleware-http]
|
||
|
|
||
NATS JetStream (NS1 loopback :4222) |
|
||
+------------------+------------------+-------------+
|
||
| | |
|
||
[job-poller] [webhook-deliver] [archive-aggregator]
|
||
| |
|
||
| HTTPS | NATS query/reply
|
||
[verae-chain-client] |
|
||
[archive-worm × N]
|
||
bloom miss = silence
|
||
```

## Completed job JSON (back to Zapier)
|
||
|

See `docs/02-architecture/archive-nats.md`. Seal receipts from chain; extra receipts and `files[]` from archive aggregation when `includeAttached` is true.
