# Drogheda Hackathon — Run-of-Show, Backlog & Gantt

> A weekend push to stabilize the fleet and de-risk the production build. Dates
> below assume a **Fri-evening → Sun** weekend; **adjust to your chosen weekend.**
> Goal: leave Monday with the backend fixed, firmware v2 bench-validated, the 4
> pulled units triaged, the thermal number measured, and the PCB schematic started.

## 1. Objectives (definition of success)

1. **Backend stops killing healthy units** — anti-jump hotfix + cell_id identity
   deployed; 500-unit slow-upstream load test passes; secrets rotated.
2. **Firmware v2 bench-validated** — recovery/backoff/LIMP/thermal verified on a
   real Blackpill + simpleRTK2B; flash candidate signed off.
3. **The 4 pulled units classified** — hardware-dead vs backend-victim; RCA updated.
4. **Thermal quantified** — a real cabinet-interior temperature from a soak test;
   battery + thermal-path decisions made.
5. **Production kicked off** — watchdog schematic → first PCB schematic draft;
   BOM + SRS signed off; Notion board live.

## 2. Tracks & suggested owners

| Track | Focus | Suggested owner |
|---|---|---|
| A — Backend | anti-jump hotfix, cell_id identity, load test, deploy, secrets | Gibran + Leo |
| B — Firmware | bench-test v2, recovery/thermal validation, flash candidate | Leo |
| C — Hardware/Thermal | soak test, battery & thermal-path decisions, conduction mock-up, fuse check | Daniel |
| D — Diagnostics | triage 4 pulled units (remote-hands/shipped), classify, RCA update | Gibran |
| E — PCB/Docs | schematic from watchdog spec, BOM/SRS sign-off | Leo + Daniel |
| F — PM/Integrations | Notion board, Drive sync, client comms, run-of-show | Adriana |

## 3. Run-of-show

| When | Block | Output |
|---|---|---|
| **Fri PM** | Kickoff; assign tracks; **backend historical triage** (htracker-online vs Wialon-offline); bench setup | which "dead" units are backend victims; benches ready |
| **Sat AM** | A: anti-jump hotfix + cell_id · B: v2 bench bring-up · C: start thermocouple soak · D: unit power-on + current-draw | hotfix in test; v2 booting; soak logging; first unit classified |
| **Sat PM** | A: 500-unit slow-upstream load test · B: forced-outage recovery test · C: battery/thermal-path decision · E: PCB schematic start | load test result; recovery proven; material decisions; schematic skeleton |
| **Sun AM** | A: deploy fixed retranslator + rotate secrets · D: finish triage + RCA update · E: BOM/SRS sign-off | backend live; 4 units classified; docs frozen |
| **Sun PM** | Integrate; **demo**; definition-of-done checklist; retro; next-week plan | go/no-go; backlog for week +1 |

## 5. Prioritized backlog (pull into Notion)

| P | Item | Track | DoD |
|---|---|---|---|
| P0 | Anti-jump hotfix (time-aware + self-heal + clear on TTL) | A | healthy unit can't be permanently dropped; unit test |
| P0 | cell_id identity (drop source-IP keying) | A | CGNAT-safe pairing; verified with 2 sims behind 1 IP |
| P0 | v2 forced-outage recovery test | B | recovers via power-cycle within backoff, no loop |
| P0 | Thermocouple soak (measure cabinet interior) | C | a real °C number over a sunny shift |
| P0 | Classify the 4 pulled units | D | each tagged dead/backend-victim; RCA updated |
| P1 | 500-unit slow-upstream load test | A | no unit dropped; metrics captured |
| P1 | Confirm ASA case survives soak (expected OK) | C | sample part survives soak |
| P1 | Battery decision (drop/LiFePO4/supercap) | C | FR-7 closed |
| P1 | Rotate MSSQL secret + purge from git | A | secret out of repo + history |
| P1 | PCB schematic from watchdog spec | E | reviewable schematic |
| P2 | Front-panel SIM / MFF2 | E | maintainability path chosen |
| P2 | Verify cabinet blade fuse | C | rated vs worst-case + inrush |

## 6. Logistics / pre-reqs

- Benches: 24 V supply with **current limit + meter**, Blackpill + simpleRTK2B +
  4G master + antennas with sky view, USB-serial laptop.
- The **4 pulled units** in QRO (ship) or remote-hands in VER —
  [[06-Testing-Validation/remote-diagnostic-protocol|protocol]].
- htracker repo + a staging caster/Wialon endpoint for the load test.
- Notion workspace + Drive access for the team.
