Document v1.2.1 platform qualification waivers

[BrettKinny]

Summary

• records Brett Kinny's 2026-08-01 version-scoped waiver for Qualify v1.2 rootless Podman on Fedora SELinux #127, Qualify v1.2 on macOS Docker Desktop #128, Qualify v1.2 Windows PowerShell and Git Bash lifecycle #129, and only the physical-arm64 criterion of Verify final v1.2.1 Candidate and publish #131
• explicitly preserves existing platform support levels and prevents this waiver from transferring to later Releases
• keeps Validate v1.2 Dev Containers and Codespaces #130 UI, final physical amd64, automated Candidate Evidence, approval, attestation, aliases, and non-rewind required

Why

The external hosts are unavailable for v1.2.1 and the release owner chose not to delay publication after the available rc5 automated, Linux, Codespaces, migration, and genuine non-1000 qualification passed. Because #127-#129 will be resolved as wontfix, the triage workflow requires a durable version-specific record; #131 remains open and only its physical-arm64 criterion is waived.

Validation

• git diff --check
• two independent reviews against the .out-of-scope/ format and issues Release v1.2.1 from one qualified Candidate #125, Qualify v1.2 rootless Podman on Fedora SELinux #127, Qualify v1.2 on macOS Docker Desktop #128, Qualify v1.2 Windows PowerShell and Git Bash lifecycle #129, Validate v1.2 Dev Containers and Codespaces #130, and the physical-arm64-only boundary in Verify final v1.2.1 Candidate and publish #131
• corrected review findings so Verify final v1.2.1 Candidate and publish #131 remains open for all non-waived final-Candidate and publication duties

Closing this waiver-only PR. We are not maintaining a per-platform manual qualification matrix for v1.2.1; automated Candidate evidence and the primary release checks remain authoritative. No code change is needed here.
