Kjell Tore Guttormsen e3b044a476 feat(ost): v5.6 C — output-style scanner (CA-OST, count 13→14)
New orchestrated scanner output-style-scanner.mjs — first new family since
SKL. Three findings, each pinned to a CONFIRMED V-row of the steering-model
plan + re-verified against code.claude.com/docs/en/output-styles:

- CA-OST-001 (medium, V10): user/project custom style missing
  keep-coding-instructions:true (default false) → silently strips built-in
  software-engineering instructions when active. Scoped to user/project.
- CA-OST-002 (low, V11): plugin style with force-for-plugin:true overrides the
  user's selected outputStyle. Verifiseringsplikt correction — the plan bullet
  said "project/user style," but force-for-plugin is plugin-styles-only per the
  docs, so the check keys on source==='plugin'.
- CA-OST-003 (medium): settings outputStyle matching no built-in
  (Default/Explanatory/Learning/Proactive, case-insensitive) nor discovered
  custom style → dead config.

Byte-stability — a scanner addition, not a field addition. Growing the
scanners array + scanners_ok cannot be hidden by a field strip, but re-seeding
frozen v5.0.0 (the SKL precedent) would now bake in B2's hotspot triple +
claudeMd drift. So, per the B2 lesson, frozen v5.0.0 snapshots are PRESERVED
and the OST entry is stripped at compare time via new
tests/helpers/strip-added-scanner.mjs (wired into json/raw-backcompat + the
Step 5/6 humanizer tests); only SC-5 default-output is regenerated (additive
OST entry, diff reviewed). OST is fixture-gated (no output styles on
marketplace-medium / hermetic HOME → silent).

Wiring: orchestrator; humanizer (OST→Configuration mistake) + humanizer-data
OST family (title-coupled); scoring (OST→Settings, keeps 10 areas). Suite
1012→1023 (+11). Badges: scanners 14, tests 1023, TRANSLATIONS families 15.
Lore swept: README, CLAUDE.md, scanner-internals, humanizer.md. self-audit A/A.

/**
* v5.6 C added the OST (Output-Style Validation) scanner — a 14th orchestrated
* scanner. The frozen v5.0.0 byte-equal baselines predate it (13 scanners), so
* this strips the additive OST scanner entry before comparison, the same way
* strip-hotspot-load-pattern.mjs handles B2's additive hotspot fields. Stripping
* (rather than re-seeding the frozen snapshots) keeps the strongest invariant:
* the ORIGINAL 13 scanners still emit byte-identical output, and the frozen
* snapshots stay free of post-v5.0.0 drift (the hotspot triple, ancestor token
* counts) that re-seeding would bake in.
*
* Removing a zero-finding scanner entry only moves `aggregate.scanners_ok`
* (OST is always status 'ok' and emits nothing on the deterministic fixture, so
* total_findings / counts / risk_score / verdict are unchanged). The strip
* decrements scanners_ok to match.
*
* Mutates in place and returns the payload for chaining inside a normalizer:
* return stripAddedScanners(stripHotspotLoadPattern(out));
