Everything built so far targets OKF v0.1. Upstream published v0.2 on
2026-07-25, so the plan records how the library relates to it and, more
importantly, who owns each decision.
Read from the spec itself rather than secondhand, which corrected two
readings that a summary had gotten wrong:
- STRICT_V1's `timestamp` is NOT a defect. Section 13.1 grants consumers a
documented fallback to legacy `timestamp` precisely when `generated` is
absent, and STRICT_V1 emits no `generated`. Nothing is asked of the wiki.
- The one measured shape problem is DEFAULT's `generated: "true"`, because
v0.2 requires `generated.by` within `generated`. That key was not reserved
in v0.1, so it was legal when written; v0.2 claimed the name. DEFAULT
states commons' ingest-spec section 5 layer, so the fix is commons' call
and is raised there as open question V1 rather than patched locally.
Two findings shrink the work. The canonical form for `generated` and a
single `verified` is an inline flow mapping, which the existing scalar
parser already round-trips as an opaque string, so block-list support is
only needed for `sources` and multi-verifier `verified` -- and only if a
named consumer asks. And the collision degrades safely: `_is_ingest_owned`
returns False for a v0.2 mapping, so a foreign concept is refused rather
than overwritten.
The track sits between Phases 3 and 4 because Phase 4 freezes the
cross-runtime contract. Freezing a v0.1 shape into two runtimes would let
the shared fixture suite certify the drift instead of catching it.
Self-imposed rule, since the spec does not require it: conform first, claim
after. Declaring `okf_version: "0.2"` is a MAY with no conformance
checkpoint, so claiming it early would be permitted -- and would be the same
class of true-sounding misleading claim as reporting a 0.2.0 measurement
under a 0.3.1 heading.
Also moves the guard 0.3.1 measurement procedure out of session state and
into execution-order.md, where it belongs.
