# Fingerprint Qualification Target Gate

Status: programming gate approved and candidate loaded; destructive configuration/flash fault and controlled power-interruption authority granted 2026-07-16; physical safety gate remains
Type: evidence
Updated: 2026-07-15
Next Action: confirm and record disconnected/simulated loads, independent over-temperature protection, accessible power disconnect, and recovery procedure before the first mutation
Campaign Reason: Historical record from campaign 009-complete-clean-contract-bound-a-b-qualification; retained independently after campaign closure and requires no separate owner-queue execution.
Campaign: standalone

## Read-only inventory

- J-Link hardware V9.60, serial `69664082`, J-Flash license.
- Target Renesas R7FS7G27H / Cortex-M4 over SWD at 4 MHz.
- Target voltage was 3.308--3.309 V.
- Attachment used memory reads only; no reset, erase, flash programming,
  VEEPROM write, register write, or power interruption was requested.
- The existing target image was running normally enough to report a main
  setpoint near 37.0 C, measured temperature near 36.6 C, and nonzero heater
  demand (snapshot value `0x95`).
- The connected unit is therefore a live thermal controller, not an approved
  expendable fault-injection fixture.

## Gate disposition

The owner confirmed on 2026-07-15 that the controller was safe for candidate
programming. Pre-load program, VEEPROM, and option-memory recovery images were
captured before programming. The candidate load and cold-power-cycle check
passed; see `work/evidence/setup-a/fingerprint-candidate-load-20260715.md`.

That programming approval was not treated as separate authority to manufacture
corrupt/ambiguous VEEPROM, interrupt flash writes, or repeatedly interrupt
power. The owner granted that separate Setup A authority in the Codex thread on
2026-07-16. The physical heater/output, independent protection, accessible
disconnect, and recovery checks remain mandatory before the first mutation.
