StillDone — Done, and still true.

Autonomous outcome verification & drift reconciliation for Alexa+

Evaluation Provenance Disclosure: This self-contained exhibit was generated from StillDone's deterministic mission engine. It replays a canonical fixture execution offline and makes no live AWS or Google API calls for visitors. Authentic historical live integration evidence is preserved separately as RECORDED_LIVE.
Canonical Intent:

“Get my family ready for tomorrow morning. We need to leave by 7:30.”

SIMULATED ALEXA+ RESPONSE — TEXT PREVIEW:

“I noticed your departure moved to 8:00 AM on Google Calendar, so tomorrow morning is no longer ready for 7:30. I have added the backpack-packing task and confirmed it is on your list, and weather is checked.”

Current System-of-Record Truth:
DRIFTED
Canonical Departure Lifecycle: 07:45 AM → 07:30 AM → 08:00 AM
1. Initial State 07:45 AM Seeded on family calendar
2. Target Verified (READY) 07:30 AM Approved update + prep task + receipt
3. External Drift (DRIFTED) 08:00 AM Moved externally → Ready revoked
