Operator GO 2026-08-23. Two findings outrank the change that triggered
the round.
OKF moved to GoogleCloudPlatform/open-knowledge-format (6265173). The
tree this repo pinned, knowledge-catalog path okf/, is now a frozen
snapshot by upstream's own notice, and the runbook's Trigger step named
it. The two trees have already diverged: the frozen copy carries a fix
(38c713f, eight tags: values as sequences rather than one plain scalar)
that the canonical repo does not.
The spec tightened without a version bump. SPEC.md still declares
Version 0.2, but every timestamp-valued key is now an ISO 8601 datetime
with an explicit offset, so a value that conformed in July does not
conform now under the same version number. Step 4 gained a fifth diff
class for it.
Our exposure is zero, measured: 10 of 10 timestamp values across the
four goldens already carry a Z offset, gated by _INGESTED_AT_RE. The
three tightened keys (stale_after, last_modified, usage_window) are
named but never written by any door. V-A8 at the new pin: 9/9 of our
bundle documents parse, 78/78 of upstream's do.
Two reference-reader behaviour changes recorded. A date-only
stale_after now reads as never stale rather than as stale -- silent,
fails open, and the class the black box cannot absorb. Timestamps now
survive a parse as written, so our ingested_at arrives as str where it
used to arrive as datetime.
No new profile: there is no new version to express. The pin move and
consumer notification are named as deliverables and deliberately not
taken here.
