Check 9 shipped in #130 to close#118, but three defects meant it could not do the job it was
added for.
Why:
- It is INFO-only, so it always exits 0 — and SKILL.md graded exit 0 "a genuine pass" and said the
script "prints nothing on success". Every check-9 INFO was discarded before it reached a report,
behind three further doors that only opened on a non-zero exit.
- `parse_field_raw()` matched `(.+)`, which does not span newlines, so only the first physical line
of a wrapped value was compared. Rewriting only the continuation line of a wrapped Description
from a hedge to a confident claim produced no finding at all — verbatim the regression #118 was
filed about. The bullet branch had the same shape: a wrapped bullet broke the loop and dropped
every later entry.
- A `git show` failure at the base ref was treated as "creation, nothing to flag" and skipped the
whole skill with no output, collapsing "absent at that ref" with "not tracked under that name".
A gitignored `.claude/skills/` copy reported clean while the authoring path reported four changed
claims. The script's own usage text promises this is "never a silent skip".
Implementation notes:
- Exit-code guidance re-keyed on output as well as code: 0-and-silent passes, 0-with-output is
INFO-only findings, 1 is FAILs, 2 never ran.
- `parse_field_raw()` is line-based and joins continuation lines; `normalize_field_text()`'s
docstring is now true rather than aspirational. A reorder deliberately fires: the two fields share
one parser, and order-insensitivity would mean splitting a prose Description on commas.
- The discarded `show_err` is now surfaced as one whole-check INFO naming both readings.
- `--base-ref=` given empty now beats the env var, as the usage text always claimed.
`validate.sh` gains an ADR-0022 `metadata.version` check at FAIL tier, because any lower tier lets
skill-author Step 4 report done on a file the commit gate then refuses. Its `read` heuristic now
skips here-doc bodies — reflowing the one offending line would have cleared the finding and left
the cause, since every usage() heredoc is one wrap from putting the English verb in column 0.
Impact: provenance tests 73 -> 82, validate tests 64 -> 72. Test 72 previously deleted origin/main
before asserting the override, so it proved the flag works with no default rather than that it beats
one; it now moves origin/main forward first.
