# Complete temperature-control profile recovery and regulation

Status: deferred
Type: campaign
Updated: 2026-08-15
Next Action: reactivate when an actual chamber is scheduled and available, attended heater-safe testing is authorized, quantitative thermal acceptance limits are approved, and the successor firmware scope is ready for chamber qualification
Campaign ID: 017-complete-temperature-control-profile-recovery-and-regulation
Campaign Number: 017
Outcome: In a separate chamber-gated successor-firmware tranche, complete temperature-control profile recovery and prove steady-state stability, overshoot, settling, door recovery, and power-recovery behavior on an actual chamber; dev fixtures may qualify preparatory logic but not thermal-plant behavior. Focus areas: 1 Firmware; 6 Qualification, release, and supply change.
Depends On: none
Decision: Do not hold the SD qualification baseline for this work. Full thermal qualification requires an available actual chamber, attended heater-safe authority, and approved quantitative acceptance limits; any inherited SD qualification for the successor firmware requires reviewed change-impact analysis and focused SD regression.
Detour For: none
Return To: none
Completion Gate: The workpackage is explicitly reactivated, implementation and fixture-level logic checks pass, actual-chamber stability, overshoot, settling, door-recovery, and power-recovery qualification meets approved limits, SD qualification inheritance or requalification is dispositioned, and current temperature-control policy and evidence are documented.
Completion Evidence: none
Disposition: Final temperature stability, overshoot, settling, door-recovery, and power-recovery qualification requires an actual test chamber. Dev fixtures may support preparatory logic work but cannot satisfy the thermal completion gate, and this separate successor-firmware tranche must not hold the SD qualification baseline.
Reactivate When: an actual chamber is scheduled and available, attended heater-safe testing is authorized, quantitative thermal acceptance limits are approved, and the successor firmware scope is ready for chamber qualification

## Request

Primary deferred workpackage:
`work/wp/deferred/wp-temperature-control-profile-recovery-and-steady-state-regulation.md`.

Fixture-only preparation may cover control logic, persistence, fault injection,
and test-plan readiness, but it must not be represented as qualification of
thermal stability or recovery. Reactivate the delivery campaign only when an
actual chamber is scheduled and available, attended heater-safe testing is
authorized, quantitative limits are approved, and the successor firmware scope
is ready for chamber qualification.

## Completion Check

The workpackage is explicitly reactivated, implementation and fixture-level logic checks pass, actual-chamber stability, overshoot, settling, door-recovery, and power-recovery qualification meets approved limits, SD qualification inheritance or requalification is dispositioned, and current temperature-control policy and evidence are documented.
