What did we decide about the auth refactor?

You are reconstructing the decision history of the auth refactor.

Using Sentra:

1. Resolve "auth refactor" as a Value Object — match against project names, code paths, doc titles, and channel names Sentra has indexed.
2. Pull every Decision Sentra extracted that is scoped to this Value Object, ordered by date.
3. For each Decision, return: the Decision statement, the Rationale, the Actor who made or led it, the Interaction it was made in (with quoted excerpts), and any subsequent Decision that revised or reversed it.

Output:

- A chronological timeline, one row per Decision, with citations.
- A short "current state" paragraph: what is decided, what is open, what was reversed and why.
- Three named open questions Sentra detected in the last 30 days that no Decision has yet resolved.
