A consumer measured our frontmatter gate against 0.2.0 and asked us to confirm
against a newer guard, correctly noting that a divergence would be a version
difference rather than a contradiction. Measured at 0.3.1: no divergence. Both
their results reproduce exactly.
Two things are sharper than what we documented yesterday:
ALL THREE ROUTES TO A MAPPING FAIL, each on a different rule -- flow {k: v} on the
disallowed value-start indicator, block on the nested-mapping check, dotted keys on
the key pattern. So the mapping CLASS has no expressible form; it is not a choice
between two shapes where one is better. That matters because OKF v0.2's `generated`
IS a mapping (`by` is required when it is present), so it cannot be expressed at
all. Pinned by a test asserting the three failures stay distinct.
T2 RUNS ON DOOR C ONLY. parse_frontmatter is referenced nowhere in the door A/B
persist path, so the same frontmatter that FAIL_SECUREs through import_bundle
passes screen_output unremarked. The grammar bounds what a consumer can RECEIVE,
never what a producer can EMIT -- which is the question a consumer's emitter design
was blocked on.
Also corrects one of our own rows: we reported "sources block list" as a single
FAIL_SECURE case. The parser distinguishes three shapes -- flat scalars parse
correctly, one key per item misparses silently to a string, two keys per item hard-
rejects. A one-element `verified:` block list passes today.
631 -> 642 passed. README item count synced.
