The gate carried a flat RECOMMENDED list ending in `timestamp`. Upstream retired
that field in v0.2: "`timestamp` is superseded by `generated.at`" (okf/SPEC.md
§13.1:802-803, read at frozen 3fcbb9f), one of the version's two breaking
changes — while :804 still lets a consumer "fall back to a legacy `timestamp`
when `generated` is absent".
A version-unconditional list cannot serve both readings. It either nags a
correct v0.2 bundle about a retired field, or goes silent about a field v0.1
still wants. So the list is now chosen by the bundle root's own okf_version:
< 0.2 (or absent/unshaped) keeps `timestamp`, >= 0.2 asks for `generated`.
Absence gets the legacy floor deliberately — §3 echoes a missing marker rather
than failing it, so it still needs a defined list.
Measured, not assumed:
- Every fixture in both corpora and both live emitters (okr, linkedin-studio)
still write `okf_version: 0.1`, so this changes NO verdict today. It is
written now because the upstream reading is fresh and pinned to a commit.
- The parity signature is conceptCount|untyped|okfVersion|okfVersionAccepted
(check-okf-parity.mjs:73-76) — warnings are not in it, so diverging from
okr's list here cannot red the parity gate. Confirmed: 9/9 fixtures pass.
- The compare is component-wise, NOT parseFloat: okf_version is version-SHAPED,
and parseFloat('0.10') is 0.1, which would sort 0.10 before 0.2 and hand a
newer bundle the retired field. Guarded by its own test.
spec §4 is updated in the same commit — a gate and the convention it enforces
must not disagree about which field they want.
Tests 98 -> 103 (okf-check 17 -> 22). All six suites green; check-versions
11 OK / 0 WARN / 0 ERROR.
