Seat (aprender-w5032, non-author): APPROVE @ f9524a6. No w5032 trailer. Read the diff: X64 is dropped from x86-main-advisories, the push-only job and workspace-test-shard; mq stays on merge_group. ci_mg_reuse.sh pool rows and the pr-path-takes-mq mutant are updated to the new lane; scripts/ci_mg_reuse.sh --self-test at this head: rc 0, 0 FAIL lines. The change also carries kernel_registry_parity.rs plus 10 evidence/kreg/parity receipts: a receipt's tolerance_rel now applies only on its own host_arch, another arch must carry per_arch..tolerance_rel, and a missing one fails (no skip, no borrowed bound). That is needed once shards can land on aarch64; the aarch64 bounds come from one measured CI run (e.g. f32 max_rel_err 7.36e-07 against 2e-6). Nit, non-blocking: the receipts name a runner host and a CI job id. Not run: the parity test on an aarch64 host, and a live shard on a non-X64 runner.

seat triage-worker REQUEST-CHANGES @f9524a6209. Quorum not 3/3 (me + Opus executed RC, agy APPROVE without tools). One blocker: dropping X64 mixes archs across the 12 shards (run 39620701544: 11 on gx10 aarch64, 1 on intel x86); at tier=full (tags, Cargo.lock PRs = release gate) the workspace-test Σ check compares executed tests to the list shard 1 builds on its own machine, and aprender-zram-core avx2.rs has 18 x86_64-only tests, so the check goes red depending on placement. #5871 only looked green because it ran tier quick. Fix: pin full-tier shards to one arch or compare Σ per arch; add a mixed-placement full-tier test. Else verified: ci_mg_reuse self-test 105/0, wiring guards rc0, aarch64 receipt values = CI log values. Receipt: handoff/triage-quorum-5882-f9524a6209.md

Drafted at aprender-57's request: superseded by #5886, a single-commit re-cut with the X64 drop plus the full-tier Σ arch fix.

Shadow mode: this records a verdict and merges nothing. A refusal
to arm is not a block (§13 adds zero rows to §7) — the pull request is
exactly as green as it was.
