AXA's accessibility QC team uses axes4 PAC (PDF/UA-1 / Matterhorn Protocol)
as their compliance gate, but our existing 9-criterion deterministic check
runs surface-level only and would pass documents PAC fails. Wired up the
existing _run_verapdf() stub so veraPDF — the open-source Matterhorn
implementation — runs as a subprocess and drives the score when available.
Verified locally: veraPDF on EAA_v1.pdf reports the exact same Content (86)
and Metadata (1) failure counts as PAC's report on the same document family,
confirming protocol parity.
Falls back cleanly to the deterministic layer when veraPDF isn't installed,
so deploys are safe before the binary lands on dev/prod servers.

New profile boots_ppack for QCing multi-page Boots production packs
(PowerPoint-exported PDFs, 4-18 pages each). Built on top of AXA's
document-mode infrastructure — branched off feature/axa-document-mode
because it reuses the dispatcher, ingest, and result writer.
New checks:
- boots_logo_compliance — three-path scoring (master wordmark / partner
lock-up / no branding) so OLIVER x BOOTS-style footer lock-ups aren't
scored against master wordmark rules. Conservative without a formal
Boots logo guideline.
- boots_colour_palette — verifies CMYK/RGB/Hex spec values on creative-
guidance pages against canonical Boots Blue / Health Primary Blue /
Offer Red, plus visual sanity-check on artwork pages.
Existing checks tuned:
- boots_brand_name_accuracy: closed-world list semantics. Brands not on
the approved list now go to names_not_on_list (manual review) instead
of failing — the list is sourced from the original 7 docs and is known
incomplete (Remington, Imodium, Maybelline etc. are legitimate Boots-
stocked brands not on it).
- boots_tandc_wording: explicit font-weight caveat — Boots Sharp Regular
vs Light isn't reliably distinguishable by vision LLM at small sizes.
Surfaced via font_weight_caveat field + needs_manual_check value.
Page classifier (document_mode/page_classifier.py):
Heuristic tags each page as cover / checklist / palette / notes /
artwork. Validated on all 10 sample packs.
Strict-grade exemption (Profile.strict_grade flag):
Only artwork-classified pages count towards Pass/Fail. Cover, checklist,
palette, and notes pages are still QC'd and reported as Informational
but cannot trigger a Fail. Banner shows exactly which artwork-page
checks fell below 6.
Result writer extended:
- Per-page table with score + page_type pill for any page_each-scope
check (auto-applied as fallback)
- Strict-grade banner (red on violation, green when clean)
- Page_type pills throughout the per-page strip
Smoke-test result (Remington 4-page pack, 2026-05-05):
Overall 70.75/100, strict-grade Fail. After two iterations of prompt
tuning, all three remaining strict-grade violations are real catches:
orphan asterisk in T&Cs, "they may not be stocked" wording deviation,
missing "Charges may apply". brand_name_accuracy 7.0 (was 3.0 before
list fix), logo_compliance 9.5 (was 1.5 before lock-up path fix).
Local-only — not pushed to dev or merged to develop until after Boots
show-and-tell. Same posture as feature/axa-document-mode.
