Upstream (~/repos/_okf-upstream @ 3fcbb9f, okf/SPEC.md) is unambiguous: a bundle-root
index.md MAY carry okf_version in a FRONTMATTER block, "the only place frontmatter is
permitted in an index.md" (§8:509-510 + §12:773-775). Through 0.2 this convention said
the opposite — no frontmatter, marker in body text. The divergence was OURS against
upstream, so 0.3 removes it rather than documenting it. Operator ruling, 2026-07-31.
Measured before deciding (date pinned to every number):
- emitters: okr (body, okf-index.mjs:204) · linkedin-studio (body, scaffold.ts:38)
· commons (FRONTMATTER, examples/nav-golden-*/bundle/index.md)
- this repo already carried BOTH forms, both green: okf-parity-corpus (9, body) and
nav-golden-corpus (4, frontmatter, byte-exact from commons @ b641741). Invisible
because the marker regex was unanchored /m, i.e. placement-blind.
THE READER IS TRANSITIONAL BY DESIGN, NOT BY OMISSION. check-okf-parity.mjs:36-39 runs
okr's LIVE checker and compares conceptCount|untyped|okfVersion|okfVersionAccepted. A
frontmatter-only reader reports null here and 0.1 there, splitting the signature on all
9 body-text fixtures — a red gate produced by a doc change, with no bundle having become
less conformant. So both placements are read, one is canonical, and placement is
DECLARED, NOT ENFORCED — the same shape §3 presence has carried since 07-23.
QUOTING WAS UPSTREAM'S OWN FORM, NOT A CORNER CASE. §12:773 is the only place in the
upstream spec showing the key with a value, and it is quoted: okf_version: "0.2". The
0.2 gate ran the shape regex on the RAW string and failed upstream's canonical example.
Fixed by unquoting BEFORE the shape check. Implemented by reusing okf-frontmatter.mjs's
existing get(), which already unquoted (lines 22-26) — no new parsing code.
okf_layout STAYS IN BODY TEXT (§12). Upstream's exception is enumerated to one key, so
the block exists by upstream's leave and for upstream's key; our own extension marker
stays outside it. Asymmetric on purpose: it survives either construction of upstream's
parenthesis — a question okr has flagged as open and we do not own.
MEASURED CONSEQUENCE, REPORTED NOT HIDDEN: okr v1.8.2 fixed their PRODUCER, not their
checker (rootMarkers/pick returns the raw string). On a quoted fixture the two impls now
diverge on the VALUE — catalog 0.2 vs okr "0.2" — measured directly via evaluateBundle.
No existing gate is affected because the corpus carries no quoted fixture, which also
means the parity gate's green does NOT cover the quoting axis: "not run", not "as
expected". The shared unquote-before-compare decision has to reach okr's CHECKER too.
Verification: suite 90 -> 98/98 (8 new; written red first — 6 genuinely failed, 2 were
regression guards already correct). Parity 9/9, red-marker-layout still diverging per
its manifest. nav-golden 2/2. git status test/ clean: NO fixture migrated — the 9
body-text fixtures are now the coverage for the transitional path.
