Network-callable Mem0-style trace memory at :3217, fronted by gateway /v1/pathway/*. Closes the ADR-004 wire-up: store substrate landed in 2a6234f, this lands the HTTP surface + [pathwayd] config + acceptance gate. Smoke proves the architecturally distinctive properties: Revise → History walks the predecessor chain backward (audit trail), Retire excludes from Search default but stays Get-able, AddIdempotent bumps replay_count without replacing — and all survive kill+restart via JSONL log replay.

// gateway is the Lakehouse-Go HTTP ingress. D6 promotes the D1
|
|
// stub endpoints into real reverse-proxies fronting all four backing
|
|
// services (storaged, catalogd, ingestd, queryd) on a single bind.
|
|
//
|
|
// Routes:
|
|
// /v1/storage/* → storaged
|
|
// /v1/catalog/* → catalogd
|
|
// /v1/ingest → ingestd
|
|
// /v1/sql → queryd
|
|
//
|
|
// The /v1 prefix lives at the edge — internal services route on
|
|
// /storage, /catalog, /ingest, /sql. Per Kimi K2 finding from the
|
|
// D1 plan review: httputil.NewSingleHostReverseProxy preserves the
|
|
// inbound path by default, so the proxy helper strips /v1 in its
|
|
// Director before forwarding.
