# Release, implement, and close the SD supply change

Status: abandoned
Type: campaign
Updated: 2026-08-26
Next Action: none
Campaign ID: 016-release-implement-and-close-sd-supply-change
Campaign Number: 016
Outcome: Finish the ECR/ECO decision and controlled rollout: settle part/specification treatment, approve and release the ECO, implement purchasing/receiving/BOM/work-instruction changes, align internal and DCS paths, and reconcile project closeout.
Primary Focus Areas: supply-change-rollout
Supporting Focus Areas: qualification-release
Depends On: 015-qualify-intended-retail-sd-breadth-and-approved-pool
Decision: none
Detour For: none
Return To: none
Completion Gate: The released ECO and implementation evidence satisfy every remaining supply-change gate, current docs and Tool Shed state agree, subordinate work is truthfully closed or dispositioned, downstream Marshal is synchronized only after workspace truth, and the project closes with no unresolved release gate.
Completion Evidence: none
Disposition: Superseded by the owner decision to change SD-card qualification direction; preserve all partial results as history without claiming qualification completion or card rejection.; replacement: Replacement roadmap, milestones, and campaigns are pending the owner follow-up discussion; requirements remain captured in work/spikes/spike-firmware-service-code-sd-qualification-direction.md and work/spikes/spike-hpt2-service-life-retrieval-performance-requirements.md.

## Request

Primary checklist: `work/checklists/checklist-sd-card-supply-change-project-closeout.md`.
Canonical truth: `docs/ecr-sd-card-supply-change-resolution.md`.

Complete Gates 5 and 6 only after all engineering and sample gates pass.
Controlled-document, ECO release, purchasing, receiving, BOM, work-instruction,
DCS, rollout, and Marshal writes require their applicable authority and direct
verification. Tool Shed and workspace truth remain authoritative; synchronize
Marshal only as a downstream mirror through the repository runbook.

## Completion Check

The released ECO and implementation evidence satisfy every remaining supply-change gate, current docs and Tool Shed state agree, subordinate work is truthfully closed or dispositioned, downstream Marshal is synchronized only after workspace truth, and the project closes with no unresolved release gate.
