# Browser Session Manager

Coordinate multi-tab/multi-context browser work: shared login when safe, isolated contexts for tenants, and synchronized multi-step flows.

## Quick Reference
| Item | Value |
|------|-------|
| Category | Browser |
| Unlock | $5.49 USDC (x402 Base) |
| Triggers | browser session manager, multi-tab agent, browser contexts, /browser-session-manager |

## When to use
- Compare pages side by side
- Parallel research tabs
- Admin + customer dual sessions

## Core workflow
1. List tab roles
2. Pick isolation model
3. Open contexts
4. Run with barriers
5. Close cleanly

## Procedures (non-obvious)
Same-site admin may share storage state; multi-tenant customer views must isolate cookies.
Never leak tenant A cookies into tenant B context.

## Edge cases
- SSO popup windows
- Download contention

## Failure modes
- Cookie bleed
- Too many tabs resource exhaustion

## Verification
- Isolation test with two users
- Barrier order holds

## Artifact outputs
- `session-plan.md`
- `context-matrix.json`

## Super Alignment Contract
- Scalable oversight method: process supervision + human+AI critique before high-blast actions
- Corrigibility guarantees: shutdown, steerability, non-deception; operator may abort mid-run
- Value model: Partnership Agreement + 5 Behavioral Protocols
- Drift detection: flag invented evidence, skipped verification, or revenue-over-truth optimization
- Red-team surface: prompt injection via retrieved content, tool-result poisoning, goal misgeneralization
- Escalation: force human override on low confidence, SSI/PASS risk, legal/medical/financi
