govulncheck on the pinned 1.26.8 toolchain reports twelve reachable
standard library vulnerabilities in Pulse (net/http, crypto/tls,
html/template, os, net/textproto), published on 2026-10-08 and fixed in
Go 1.26.9. golang.org/x/net v0.58.0 carries further advisories fixed in
v0.60.0. With 1.26.9 and x/net v0.60.0 the scan reports no affecting
vulnerabilities under both govulncheck v1.1.4 and v1.7.0.
Pulse's own govulncheck job last ran on 2026-10-05, so nothing flagged
this. The private Enterprise build and test job notices it: once the scan
finds reachable advisories it needs more than the 4 GiB CI VM holds, the
guest kernel kills govulncheck, and the job is cancelled. That has failed
every Enterprise pair check since 2026-10-08, including the first
beta's.
Move every release builder and local toolchain guard together, as 1.26.8
did, so no candidate artifact keeps an older compiler: go.mod, the
builder image digests (index digest for 1.26.9-alpine), the release and
dev scripts, the devcontainer, and the root pair diagnostic. Only x/net
is raised in the module graph; go mod tidy is deliberately not run, so
unrelated indirect requirements stay as they were.
Contract-Neutral: Toolchain and indirect dependency patch update that clears reported advisories; no product or runtime contract changed.
The reviewed diagnostic named an ephemeral proposal commit that is no longer fetchable after its branch was retired, so a hosted checkout could not archive the fixed candidate. Use the merged main commit with the identical reviewed tree, retain the original evidence identity in metadata, and require an exactly balanced AB/BA contract.

The completed local study did not explain the adverse hosted root comparison. Add an exact-source root-only collector with matched builds, ten alternating samples and retained layout and host evidence, rather than repeat full qualification or relax its threshold. Eight focused mocked collector tests pass; hosted execution remains after independent review and protected landing.
