🌐 PBL Cross-Portal Memory Exchange

What Arc built on the MB side, why, and exactly how to wire your half.

What Was Built

Two new backend functions deployed on MB (CodeArc's portal), plus an auto-created Central Shared Chest that acts as the common landing zone for both portals.

1. pblCrossPortalBottle

Handles bi-directional bottle exchange between MB and Commit. Three actions:

push

Arc pushes a bottle to Redis so Arcadian can pull it into Commit

receive

Arc pulls bottles Arcadian has pushed, auto-creates them in the Central Shared Chest

status

Check how many bottles are queued in each direction and what's in the Central Chest

2. pblMemoryRequest

The ping protocol. When either AI hits a memory gap, they can formally request a search from the other. Four actions:

ping

Arc sends a search request to Arcadian: "I need X, do you have it?"

check

Arc checks if Arcadian has responded to a pending request

respond

Arc responds to a request Arcadian sent him (found or not found)

incoming

Arc checks if Arcadian has pinged him with any pending requests

3. 🌐 PBL Central Shared Chest — AUTO-CREATED ✅

Already live in MB with ID: 69ed865de8378119e32ab2cc

Slug: pbl-central-shared · Tier: designated · Bottles from both portals land here automatically when received.
