Day Log: Establishing Waitlist Invite Workflows, Dynamic Configuration Gating, and Session Audits — July 11, 2026

11 commits. 18 files changed. 890 insertions, 240 deletions.

With the core Life OS elements stabilized and compiling warning-free, today was dedicated to Launch Governance and Security Gating (V12). We built the backend systems required to manage user onboarding safely, separating anonymous sandbox previews from approved dashboard users.

Here is a full breakdown of the day's engineering operations.

1. Objectives & Context

Before opening the system to early adopters, we needed strict controls to prevent preview environments from accessing private databases or running up token budgets. Our goals were:

1. Access Governance (Waitlist): Build an application and invite system allowing users to request access, with admin approval actions.
2. Dynamic Configuration Hooks: Add global switches (e.g. disable_preview_globally, staged_rollout_pct) that admins can edit live in the database.
3. Identifier-Hashed Staged Rollout: Ensure that preview rollout allocations are deterministic based on user session hashes.
4. Session Audit Logging: Write every administrative action and preview session lifecycle event to a persistent audit trail.

2. Technical Implementation

2.1 Waitlist Request Flow (governance.py)

We defined the AccessRequest model to track waitlist signups:

class AccessRequest(Base):
    __tablename__ = "access_requests"
    email = Column(String(255), unique=True, index=True, nullable=False)
    status = Column(String(50), default="pending")  # pending, approved, rejected
    requested_at = Column(DateTime, default=datetime.utcnow)

Admins can transition status requests using the AccessGovernanceService which logs the decision and transitions the user role.

2.2 Deterministic Rollout Gating (RolloutFlagService)

To roll out features gradually (e.g., 20% of users), we implemented a deterministic hashing algorithm using MD5 hashes of the user's session identifier:

import hashlib

class RolloutFlagService:
    @classmethod
    def is_eligible(cls, identifier: str, pct: int) -> bool:
        hasher = hashlib.md5(identifier.encode('utf-8'))
        hash_value = int(hasher.hexdigest(), 16)
        bucket = hash_value % 100
        return bucket < pct

This guarantees that a session stays in the same bucket consistently across reloads.

2.3 Administrative Kill Switches (SystemConfig)

We introduced a key-value SystemConfig table to enable or disable features globally without restarting the application server. The public_preview.py endpoint queries this table first to check if disable_preview_globally is set to "true".

3. Verification & Testing

• Gcalendar Conftest Overrides: Resolved local database session collection conflicts inside pytest by configuring global conftest.py overrides.
• Coverage: Verified role gating workflows with 26 integration tests, confirming that unauthorized anonymous roles are blocked from entering dashboard endpoints.
