K3-22. SPEC SS 11 point 1: "Every non-reserved `.md` file in the tree
contains a parseable YAML frontmatter block." Measured with PyYAML 6.0.3,
okf's own default K2 bundle failed safe_load on 41 of 455 blocks and the
R761 build on 1 of 2 763, every one a block scalar written verbatim.
Block (the profile emitter, every key): a value the K3-19 rule refuses as
plain is written double-quoted, `\` and `"` escaped; every other value keeps
its bytes, and a flow collection or an empty value is written as it stands.
The rule, now `profiles.yaml_block_plain`, agrees with PyYAML on every
top-level value in eleven measured trees (0 refused that it reads verbatim,
0 kept that it does not). Double, never single: 0 values in those trees are
`"`-wrapped and 11 193 are `'`-wrapped.
Flow (`sources`, Door A and Door B, and a run-stated flow value): the pinned
guard refuses ANY quote in a flow mapping (1.3.0, measured), so a leaf PyYAML
needs quoted has no form both read. `yaml_flow_plain` refuses it instead:
`,[]{}`, `?`, a quote, ": ", " #", a trailing `:`, a leading indicator -- a
leading `-` before a non-space excepted, which both readers take. The file
name is checked too, because it is the entry's `title` when the document
declares none. Existing codes: inbox_source_file_unaddressable,
inbox_source_title_unaddressable, source_reference_unquotable,
run_frontmatter_invalid.
Readers: parse_frontmatter, profiles' and structure's copies, and both
read_sources branches unquote a `"`-wrapped value (`\"` and `\\` decoded,
nothing else); `'`-wrapped values are untouched, and structure keeps the
single-quote rule it already had. The flow-mapping split is quote-aware, so
`{ title: "a, b" }` is one pair. The generated SKILL.md header goes through
the same block rule.
TWO K3-19 TESTS MOVED, deliberately: test_run_frontmatter built with
`sources=[{ resource: ...?languageCode=nb, ... }]`, the exact form PyYAML
refused on 2 761 of 2 761 frontmatters of K3-19's flagged build. The two
build tests now write an address without `?`; the flag-grammar test keeps
the `?` address (it only splits), and a new test holds that the build
refuses it with exit 2 and writes nothing.
1753 passed, 1 skipped (OKF_HTML_CORPUS, known). No golden moved.

Red first (K3-19 b). A consumer's own build of the same kind of source
carries `description`, an edition key and a `sources` entry addressing the
publisher's URL -- eight keys of its own, `okf check` 0 findings -- and
`okf build` could carry none of them without a line of Python. SPEC SS 4.1
"Extensions" lets a producer add any key; SS 11 forbids a consumer to reject
one.
30 of 30 red on ee8d5b5, measured before any implementation: the flag does
not exist, nor `cli.frontmatter_from_flags`, nor `build(frontmatter=...)`.
They pin the form (split on the FIRST '=', one verbatim line, readable back
through parse_frontmatter and consume.read_sources), the precedence (a
stated `sources` replaces the derived one and never adds a second line), that
the flag adds exactly its line and moves nothing else, and the refusals
before anything is written: every key the door writes itself, and every pair
that would not read back as stated.
