Real-World Operational Crisis

The Campus Placement Crisis & The "All-or-Nothing" LLM Trap

Why traditional AI coding tools and manual spreadsheets break down under high stakes.

The Placement Office Nightmare

Manual Notice Decoding: Placement coordinators process 50+ unstructured job descriptions per season under tight deadlines.
Spreadsheet Formula Errors: A single mistaken filter excludes eligible students or invites campus legal disputes.
Terminal Isolation: Non-technical placement heads and HR officers cannot see or audit CLI coding tools.

The "All-or-Nothing" LLM Trap

Floating-Point Math Hallucinations: Frontier LLMs fail at reliable inequality checks on GPA cutoffs (e.g. 7.96 vs 8.00).
High Latency & Costs: Passing every trivial check to cloud models takes 2–5 seconds and burns API credits.
Prompt Injections: External recruiter notices carry malicious injection payloads that trick open agents.

Cognitive Systems Engineering

Kahneman Dual-Process Architecture (System 1 + System 2)

Decoupling fast neural reflexes from deliberative multi-agent collaboration.

System 1: Laya Fast Reflex Engine

<5ms Latency on CPU · Zero Token Cost

Pre-screens all recruiter notices for prompt injections and jailbreaks before LLM context ingestion.
Routes room messages and evaluates confidence: <0.75 triggers human clarification gates.
Scores candidate spoken answers against the STAR framework in sub-second time.

System 2: Switch AI Multi-Agent Bus

Deliberative Collaborative Rooms · Auditable State

Persistent PostgreSQL row-backed message bus with workspace Row-Level Security (RLS).
Drive Coordinator (@coord): Ingests notices and manages human approval gates.
Eligibility Auditor (@auditor): Runs deterministic Python math and issues SHA-256 receipts.
Career Coach (@coach): Quarantined in Room 2 for personalized candidate prep.

Switch AI Deep Integration

Why CampusHire Relay Fundamentally Depends on Switch AI

Direct architectural mapping to Switch's enterprise collaborative primitives.

PostgreSQL RLS Message Bus

Every message, extracted JSON brief, approval, and audit log is stored immutably in PostgreSQL, surviving agent and server restarts.

Role-Based Addressing Policy

Decouples access: @coord has addressing: anyone, while @auditor is locked to addressing: owner-agents.

Room Instructions

switch/room-instructions.md briefs all agent sessions on governance rules: Laya screening, human sign-off, and PII minimization.

Room Documents

Approved criteria (drive_brief.json) and cryptographic receipts (audit_receipt.json) are stored permanently via !list-documents.

Three-Factor Security

Dismantles the unsafe triad: Unsupervised Action + Critical Reach + Unvetted Input through mandatory human approval gates.

Console Templates

Packaged as campus-hire.template.yaml for one-click deployment across Mattermost, Slack, Discord, and Teams.

2024–2026 Peer-Reviewed Literature

Academic Multi-Agent Literature Grounding

Empirical findings that justify CampusHire Relay's architectural choices.

MAST Failure Taxonomy (UC Berkeley 2025)

1,642 traces proved uncoordinated agents amplify errors by 17.2× vs 4.4× with centralized coordination. Switch rooms provide that exact centralized coordination layer.

ProgRouter (ACL EMNLP 2026)

Step-wise routing: local neural reflex (Laya) for sub-5ms filtering and intent routing; LLMs for semantic synthesis; deterministic Python for tabular math.

Human-Agent Collaboration Survey (ACL 2026)

Human Agency Levels A3/A2 reduce cognitive supervisor burden. Placement officers supervise high-leverage gates rather than manual spreadsheets.

MetaGPT & ChatDev (ICLR 2024 / ACL 2024)

Typed intermediate schemas (drive_brief.json, audit_receipt.json) and strict instructor-assistant role separation reduce corrections by 67%.
