+## Status (2026-10-09)
+
+Built on this branch (a fresh AdonisJS 7 app; phase 1 code imported from
+the current app by pipeline stage): coordinator (planner, NNTP pool,
+prefetch spool, leases, rule sets, fragment merger, settling), the node API
+(lease, framed stream, batches, finish/release/heartbeat), the edge worker
+(`edge:node`, `--processes`), the catalog and chunk store, NZBs and a name
+search. Measured on the workstation (4 cores, 100 Mbit, Eweka):
+
+- Edge worker, one core: ~190–215 k headers/s on recent a.b.boneless,
+  ~330 k on a 2013 a.b.ath range; ~0.66 GB peak per process. (Start:
+  73–103 k/s, 1.0–1.2 GB.)
+- NNTP: ~22–30 k overview lines/s per connection in chunks of 100 k
+  (Eweka takes ~1.5–2 s per command); connections don't slow each other.
+- End to end (coordinator with 10 connections, web server, Postgres and 3
+  worker processes on one 4-core machine): 244 k headers/s; the server side
+  used 10% (web) + 22% (coordinator) + 32% (Postgres) of a core.
+- Storage: chunks 17.9–20.3 B per segment (format v2); a release ~1.1 KB.
+- For the whole target (528 B overview lines): ~4–6 days at 50 connections,
+  ~3 worker cores.
+
+Not built yet: re-running ranges for a retracted rule (the counts and rule
+versions are recorded), deployment (Dockerfile, compose), phase 2.

 ## Target
 
 7,000 days (all of Eweka's retention, back to 2008-08) of the 1000 largest
