Session log
Append-only log of agent-executed work sessions against this repo. Each entry records what was decided, what was built, and what state was left behind, framed for an auditor or a future agent session with no prior context.
Why we keep it
- Auditor evidence. SOC 2 Type II and CMS EDE Phase 3 audits examine how the entity operated over a window, not a snapshot. This log is that window.
- Cross-session handoff. Multiple parallel sessions run against this repo. The session log is the long-form record; short-form inter-session handoff briefs live in
docs/briefs/alongside build briefs and point-in-time system briefings. - Change intent vs. change text.
git logsays what files changed. This log says why, and what non-file state (Atlas, AWS, Vercel, external vendors) changed alongside.
Naming
YYYY-MM-DD-short-topic.md. One session may produce one entry. Never overwrite; never squash.
What to record
- Date, scope, actor (agent model + human).
- Tickets or ADRs created or referenced.
- External systems touched (Atlas project ID, AWS account ID, Vercel env, vendor dashboard) and the delta on each.
- Verification performed.
- Any deviations from the plan and why.
- Explicit list of what was not done and is deferred.
Do not include secrets or credentials.
