Module 3 — Post-Event

The ride is over. The troopers have the guy. Now the system has two jobs left — one for the courtroom, one for Maria. One holds up legally. The other holds up as a human being. This module does both.

Why this module exists

The 30-second emergency is the marketing. The 30-day aftercare is the company. This is the part competitors can't copy, regulators can't dismiss, and drivers actually remember.

⚖️

Evidence that holds up in court

UC-12 doesn't just give a detective a video file. It gives her a notarized chain-of-custody PDF, a SHA-256 manifest, and a chain-of-custody log signed under Fed. R. Evid. 901 & 902. The recording has to win a motion in limine before a Fulton County judge.

🩹

Care that holds up in life

UC-13 converts a one-time trauma into a five-year subscription. Free therapy, lost-fare reimbursement, workers'-comp paperwork already filled. The driver who feels supported in the first 24 hours doesn't churn at 90 days.

The lever nobody talks about

PTSD-driven churn is the silent killer of every safety app. Mayday's aftercare is built to halve it — same measurable outcome as the capture loop, but quieter, slower, and worth more per user than any of the emergency features.

UC-12

Evidence handoff

Actor: Maria + Mayday + Detective Alvarez (case #2026-GA-048812) + Fulton County DA

1Detective Alvarez (case #2026-GA-048812) requests the recording. Maria consents in-app: 4-digit PIN + biometric.
2
Mayday generates the Evidence Bundle:
- One-page incident PDF
- Original MP4 (encrypted; decrypted server-side for review)
- SHA-256 manifest of every chunk
- GPS + IMU + barometer log
- Full operator transcript (Jordan + AI + Maria)
- Append-only chain-of-custody log
3Detective receives a one-time signed URL (24h) to download, plus a notarized chain-of-custody PDF — Mayday is an authorized e-notary in Georgia.
4Passenger arrested 9 days later, identified via Lyft's facial-recognition partnership (with warrant). Recording is admitted as evidence at trial.
5Mayday retains the original 1 year (or per Maria's preference — she picks 1y), then auto-deletes per privacy policy.

Compliance anchors:
• Fed. R. Evid. 901 (authentication) — chain-of-custody PDF + notarized hash.
• Fed. R. Evid. 902(13)/(14) — certified records from a digital process.
• GA two-party consent (OCA §16-11-66) — recording disclosed on AI/human handoff (per UC-9 step 2).

UC-13

Post-incident care (aftercare)

Actor: Maria + Mayday + partner orgs · The highest-impact part of the product for actual user recovery

1Within 1 hour: Mayday sends "Maria, are you okay? Tap here if you want to talk." — passive check-in, no nag.t = +1h
2Within 24 hours: Mayday prompts Maria — "How are you feeling?" Quick-reply chips:
😟 I'm shaken but OK 💬 I want to talk to someone 🌙 I want to take the night off ✅ I'm fine, back to driving
3If she picks "shaken" or "talk to someone" → Mayday books a free 30-min session with a partner therapist (Lyft Healthcare for Lyft drivers, RAINN for non-Lyft users). Slot opened inside the app; no forms to fill.
4Workers'-comp paperwork pre-filled for Lyft (assault-on-driver is covered in most states — CA, NY, IL first to mandate). Maria reviews in-app, e-signs, Lyft processes.
5Mayday offers free shift-cash reimbursement: $250 Lyft credit for lost fares that night. Auto-applied to Maria's Lyft driver wallet within 5 minutes.
6Optional — anonymous story sharing (with explicit consent) for Mayday PR and future audio-event ML training. Off by default; never required.t = +72h
730-day check-in: "Are you still driving? Want us to tune your trigger phrase to be more sensitive / less sensitive?" Drill re-prompted if she hasn't done one this month.t = +30d

Why it matters:
Aftercare is the lever that turns a one-time user into a 5-year subscriber. It also reduces PTSD-driven churn — and is the highest-impact part of the product for the user's actual recovery. Drivers who feel supported in the first 24h churn at less than 1/3 the rate of those who feel abandoned.

Outcome of Module 3

Two outcomes, two timescales. In court: the man who grabbed her arm is convicted on a recording with a notarized chain of custody and admissible under Georgia two-party consent. In life: Maria talks to a therapist on Sunday, takes Monday off, drives again on Tuesday with a trigger phrase tuned to her voice. She stays subscribed. She tells another driver. They install.
