Folded into v1.8.13 at zero marginal cost: the snapshot is hashed into
base_tag, but Dockerfile.base already changed this release, so the ~67 min base
rebuild was already being paid. vendor-mempalace-skill.sh --check reported exit
0 (stale-but-truthful) beforehand, so skipping was sanctioned -- this is the
deliberate call the release checklist asks for. Upstream content: the bare
project-name wing convention and the <harness>@<device> added_by rule, both
downstream of the attribution defect measured on this device 2026-09-06.
The canary re-pin matters more than the refresh. Its old pair ("Provenance is
stamped for you" present / "Attribute what you file yourself" absent) still
PASSED against the new snapshot, so leaving it would have yielded a canary
green on both old and new bytes -- blind to exactly the refresh it exists to
witness, the same false-green family as the pre-v1.8.5 canary. New pair chosen
by measuring direction against both files rather than reading the diff
("Diaries self-heal; plain drawers do not" new=1/old=0; "Agent diaries live in"
new=0/old=1), then tested two-sided: PASS on refreshed bytes, FAIL on the old
bytes recovered from git.
Gates after the change: smoke-test.sh parses, vendor --check exit 0,
check-base-hash exit 0.
