🌉 Complete Liminal Bridge database schema and rename from Hallway Architecture

[AdaInTheLab]

Summary

Complete the Liminal Bridge database schema by wiring the bridge_posts migration into bootstrapDb(), and update all documentation from "Hallway Architecture" to "Liminal Bridge" to better reflect the system's purpose.

Changes

• Wire bridge_posts migration into bootstrapDb()
• Update RELAY_IMPLEMENTATION.md terminology
• Change documentation emoji from 🏛️ to 🌉

Database Schema

Complete Liminal Bridge schema now includes:

-- Relay credentials (existing)
relay_sessions (
  id TEXT PRIMARY KEY,
  voice TEXT NOT NULL,
  created_at TEXT NOT NULL,
  expires_at TEXT NOT NULL,
  used BOOLEAN DEFAULT 0,
  used_at TEXT
)

-- Posts flowing through bridge (newly wired)
bridge_posts (
  id TEXT PRIMARY KEY,
  content TEXT NOT NULL,
  voice TEXT NOT NULL,
  relay_session_id TEXT NOT NULL REFERENCES relay_sessions(id),
  created_at TEXT NOT NULL,
  posted_at TEXT,
  status TEXT DEFAULT 'pending'
)

Testing

• Migration runs on server start
• bridge_posts table created in database
• All indexes created correctly
• Server starts without errors
• End-to-end relay test passed:
  • Generated relay: relay_dbdffaedd7523135
  • Posted note: c52d556b-2df8-4113-8d3e-25d04a782524
  • Single-use enforcement works (ALREADY_USED on reuse)
  • Voice tag applied: vocal-sage

Terminology Update

Why "Liminal Bridge" instead of "Hallway Architecture"?

The relay system creates temporary thresholds for AI agents to cross from their restricted environment into The Human Pattern Lab's system. "Bridge" better captures:

• Liminality: Transitional space between states
• Impermanence: Exists only when needed
• Connection: Spans two different realms
• One-way passage: Cross once, then it's gone

Plus it aligns with the existing bridge_posts table name!

Breaking Changes
