docs(okf-v0.2): V-A8 executed green, and the two premises it falsified

V-A8 was scheduled to be WEAKENED to parse-and-render on the standing claim
that "there is no validator in okf/". Enumerating the repository tree instead
of that one subdirectory falsified it: OKFDocument.validate() sits at
okf/src/reference_agent/bundle/document.py:58 inside a working v0.2 reader.

So V-A8 ran as written, and passed 13/13 against
examples/ingest-golden-okf-v0-2/ at pinned 3fcbb9f. It needs nothing installed
-- document.py imports only yaml -- so .venv and the one-runtime-dependency
rule are untouched. The load-bearing assertion is not validate() (which checks
a single key, `type`); it is that a REAL yaml parser recovers our inline flow
forms as structures: `generated` as a mapping, `sources` as a list of mappings.
Our own parser is line-oriented and reads both as opaque strings, so no test of
ours could ever have answered this.

Second falsified premise, in the A-E6 rationale itself: "yaml.safe_load returns
"0.2" whether or not it was quoted". Measured against PyYAML 6.0.3 (the version
upstream requires), unquoted loads as float 0.2 and quoted as str '0.2'. The
BOM half of the same sentence is true. Correcting it surfaces what it hid --
unquoted `0.10` loads as `0.1`, indistinguishable from v0.1, and the type is
not stable across version shapes (`0.2` float, `0.2.1` str). Upstream's only
written instance, SPEC.md:773, is quoted.

That changes nothing today and D5 is NOT requoted: at 0.2 both forms are
unambiguous, and neither consumer reading the key parses YAML. It is recorded
because okf_version's value belongs to catalog (E1), so it is a constraint we
owe them, not a choice we may make for them.

Runbook: Step 2 now enumerates the REPOSITORY root, not okf/ -- the same
mistake this step already warned about, repeated one level up (toolbox/ and
samples/ sit outside okf/; 265 tracked files, 48 py + 43 ts, none of it on any
list). New Step 3a carries the V-A8 procedure per upstream release, including
that it can never be a pytest test and why.

Both are asserted on **raw bytes**, never on a parsed value: `yaml.safe_load`

Both are asserted on **raw bytes**, never on a parsed value. **The reason given
here was half wrong, measured 2026-07-31 under V-A8, and the correction matters
more than the sentence did.**
*What it said:* "`yaml.safe_load` returns `"0.2"` whether or not it was quoted
and strips a BOM before any caller sees it, so a parsed assertion masks precisely
these two defects."
*Measured against PyYAML 6.0.3 — the version upstream's own `pyproject.toml`
requires:*
| Input | `safe_load` returns | Type |
|---|---|---|
| `okf_version: 0.2` | `0.2` | **float** |
| `okf_version: "0.2"` | `'0.2'` | str |
| BOM + `okf_version: 0.2` | `{'okf_version': 0.2}` | BOM stripped, key clean |
So the **BOM half is true** — a parsed assertion genuinely cannot see a BOM, and
that is the whole reason the BOM expectation is a byte assertion. The **quoting
half is false**: the two forms are not merely distinguishable after parsing, they
come back as *different types*. Raw-byte assertion remains the right call for
quoting too — the two consumers that actually read this key parse line-oriented,
so bytes are what they see — but it is right for that reason, not because parsing
cannot tell.
**The correction carries a finding the original claim was hiding**, and it is
about the value space rather than about this fixture:
- Unquoted, `okf_version: 0.10` loads as `0.1` — **indistinguishable from v0.1**
to any YAML-parsing consumer. Quoted, `'0.10' != '0.1'`.
- Unquoted, the *type* is not even stable across version shapes: `0.2` is a
float, `0.2.1` is a str.
- Upstream's only written instance of the key (`SPEC.md:773` @ `3fcbb9f`) is
**quoted**: `okf_version: "0.2"`. None of its four shipped bundles emit the key
at all, so the spec line is the entire prior art.
**This changes nothing today and is not a reason to requote D5.** At `0.2` both
forms are unambiguous, and neither consumer that reads the key parses YAML:
commons is line-oriented (`method-spec.md:90`) and catalog's gate unquotes before
a text-shape regex (`1ca27f6`). The exposure is latent and bounded — it opens at a
two-digit minor or a three-segment version. It is recorded here because
`okf_version`'s **value** belongs to catalog (decision E1), which makes this a
constraint we owe them before such a version exists rather than a choice we may
make for them.

V-A8 is the one that keeps this honest. Every other test asks whether we agree
with ourselves.
**Executed 2026-07-31, and it was nearly weakened on a false premise.** The
standing note said V-A8 had to be re-scoped to parse-and-render because "there is
no validator in `okf/`". Enumerating the tree instead of the subdirectory showed
`OKFDocument.validate()` at `okf/src/reference_agent/bundle/document.py:58`, inside
a working v0.2 reader. The claim was a negative derived from a partial enumeration,
which is the failure mode runbook Step 2 now names explicitly.
The test ran unweakened. `document.py` imports only `yaml`, so upstream's reader
runs standalone against the pinned clone with nothing installed and `.venv`
untouched. **13/13 green** over `examples/ingest-golden-okf-v0-2/`:
- Both files parse under a real `yaml.safe_load`.
- `generated` arrives as a **mapping** — `{'by': 'process:okf-ingest', 'at':
datetime(2026, 7, 16, 12, 0, tzinfo=utc)}` — and `sources` as a **list of
mappings** carrying `id` and `resource`. This is the assertion no test of ours
could make: our parser is line-oriented and reads both as opaque strings.
- `validate()` passes, `trust_tier``unverified`, `normalize_verified``[]`,
`is_stale``False`, and `serialize()``parse()` preserves frontmatter
semantics and body bytes.
Two measured facts worth carrying, neither of them failures:
1. **`generated.at` type-coerces to `datetime`** under a real YAML parser while our
parser keeps the string. Same one-way asymmetry po-claude reported from the
other side on 2026-07-31 (their line-oriented parser sees the whole mapping as
one opaque string). Neither is wrong; ownership recognition
(`OwnershipPolicy.owns`) is a string prefix test and is unaffected by either.
2. **`serialize()` reflows our inline flow forms to block form.** An upstream
round-trip therefore yields bytes our own parser cannot read — the exact
pollution `test_a_block_list_pollutes_the_scalar_parsers_key_space`
characterizes. Expected, one-directional, and not a reason to emit block form.
**V-A8 cannot become a pytest test**, and that is not a gap: it needs PyYAML and
upstream's source, and this package has exactly one runtime dependency with a
packaging test enforcing it. It is a per-release runbook procedure (Step 3a), which
is also where an upstream reader change would be caught.
