Kjell Tore Guttormsen 44e2b31afd test(okf): pin the two boundary classes the new carriers introduced 
Probed after 1.3.0 landed, on advisor challenge. Both came back clean --
these pin them so they cannot regress silently.

1. A `- ` item whose text begins with a YAML indicator AND carries a `": "`
   could in principle route into the block-mapping path with a
   half-validated key instead of into `_reject_dangerous_value`. It does
   not: `&anchor id` fails `_KEY_RE` on the key side, so the item falls
   through intact and raises on the indicator. One row each for & * ! %
   backtick, plus the merge key inside an entry.

2. `_consume_block_mapping` ends at a blank line and at column zero, and
   hands an index back to `_consume_block_list`, which hands one back to
   `_parse_flat`. A line orphaned by that boundary -- a `resource:` left
   over from a mapping that closed early -- must RAISE, not be dropped. A
   pointer that vanishes rather than failing is this repo's failure class,
   so it gets a test rather than a probe. Plus the return-index contract:
   a top-level key after a multi-entry list is neither swallowed nor
   re-read as an item.

868 green (was 859), 130/130 classes. Test-only; no source change.

"""Tests for the OKF adapter (v0.2 stream 1).
The adapter sits *on top of* the format-agnostic core: the core stays
`text -> findings`; the adapter knows OKF structure and feeds scannable text
regions into the existing machinery. No YAML/format awareness leaks into core.
T2 — frontmatter parse-safety gate. A *strict, reject-by-default* loader for the
minimal OKF frontmatter subset (flat `key: value` scalars + block `- item`
lists). Every construct the "block anchor/alias DoS + dangerous type coercion"
requirement names is a hard reject, by construction — you cannot suffer a
billion-laughs expansion if anchors are refused before parsing.
OKF spec facts used here (verified against okf/SPEC.md, 2026-07-06):
- `type` is the only REQUIRED frontmatter key; `title`/`description`/`resource`/
`tags`/`timestamp` are recommended; producers MAY add arbitrary keys.
- frontmatter is minimal by design — a flat block of scalars plus a `tags` list.
