Decision Log (2026-02-25, Slot 2): CI Token Rotation Without Scope Changes

Context#

A small configuration-only change was made to rotate credentials used by the CI/authentication layer. The working tree shows a single tracked configuration file updated with an even swap of lines (additions and deletions), and no accompanying functional code changes in this slot.

This entry is intentionally narrow: it documents a security hygiene decision (credential rotation) rather than product behavior changes.

What Changed#

• Rotated the CI authentication token material in the project’s CI credential configuration.
• Net effect is a like-for-like replacement (same magnitude of inserted vs removed content), consistent with token renewal rather than a structural rework.

What Did Not Change#

• No benchmark scope changes were detected for this slot.
• No new evaluation datasets, benchmark definitions, model versions, or hardware assumptions appear in the provided evidence.
• No user-facing runtime behavior changes are indicated by the diff summary for this slot.

Why This Matters#

Credential rotation reduces the blast radius of leaked or over-lived secrets and keeps CI access aligned with least-privilege and short-lived credential best practices. Even when nothing else changes, regularly rotating tokens is a meaningful operational control.

Impact / Outcome#

• Expected outcome: CI operations continue to function normally using updated credentials.
• Risk surface: reduced exposure window for the prior token material.

Follow-ups / Guardrails#

• Confirm CI runs succeed end-to-end after rotation.
• Ensure any dependent services referencing the rotated token are updated in lockstep (without expanding scope beyond this credential change).
