P15 (order 20260912T220951Z). okf._frontmatter_from_text was linewise
last-write-wins over EVERY line regardless of indentation, so a curated
concept's own top-level `title:` got silently overwritten by the nested
`sources:\n - title: ...` block's title. Fix: a top-level (unindented)
key always wins over an indented one of the same name; a nested line
with no top-level counterpart is still preserved (SPEC §4).
Red-before/green-after: new test
test_parse_frontmatter_top_level_title_survives_nested_sources_title
(tests/test_okf.py) failed on 45edbf5 (fm["title"] == "N500:2024",
expected the concept's own), green after the fix.
Re-measured on all four vegnormal-okf bases (concept files / distinct
titles): n100-2023 446/446 (was 1) - n200-2024 1133/1133 (was 1) -
n500-2024 270/270 (was 1) - r761-2025 2756/2407 (genuine repeated
process names, not a collapse). directory_listing on krav/N500:
269 documents / 269 distinct titles (was 1).
tests/test_context_sets_loadbearing.py:
- The P14 tripwire test (asserting parse_frontmatter DID collapse
titles) is INVERTED, not deleted, per the order: it now asserts the
fix holds, as a live regression guard.
- own_frontmatter() stays (not replaced by parse_frontmatter): measured
29,500 field reads (type/title/req_number/prosessnr, all four bases)
agree exactly except for quote-stripping (2,728/29,500, zero value
mismatches) - own_frontmatter unquotes for fasit comparison,
parse_frontmatter deliberately doesn't (D1/(a)/(i): unquote_scalar is
the ONE unquoting rule).
docs/2026-09-12-p14-kontekstsett.md Part B correction: the "22 of 22
cost words absent from n100/n200/n500" claim was false - n500-2024
carries `kroner` as a false positive (substring match inside
"borkroner", drill bits, not money). The original 22-word list was
never persisted, so only ~9 of the 22 survive named. Replaced with a
newly named, persisted 22-word list and the actual re-measured count:
n100 22/22 absent - n200 22/22 - n500 21/22 (kroner via borkroner) -
r761 18/22 (4 genuine cost words). No gate touched (no fasit anchor is
`kroner`).
Verification: full suite 1643 passed / 5 skipped (was 1642/5 on
45edbf5, +1 new test, 0 removed) - `uv run pytest -q`. ruff check +
ruff format --check clean on the three changed source/test files.

No version bump, no push (both forbidden by the order).
