Single Gemini call per asset. Prompt assembles attached Source
Messaging summaries + media-plan language context + the asset image.
Returns structured JSON with score, summary, and a findings array
(priority, category, quote, issue, suggested fix, source reference).
Empty findings = clean asset; missing reference -> score 0 with a
clear message rather than running blind.
Mirrors the boots_tandc_wording pattern: subclass FlaskAppTemplate,
expose a static prompt template, let process_single_check inject
reference-asset content and media-plan context at runtime. A
standalone build_prompt() helper mirrors that assembly for unit-
style smoke tests and ad-hoc prompt inspection.

Moves the Dow Jones / MarketWatch / WSJ profile JSONs (4), check apps
(22), and CLAUDE_DOW_JONES.md into backend/_archive/dow_jones/. All
moves use git mv so history follows. Adds a restore-instructions
README. No loader changes needed — the archive lives outside the
scanned directories.

- wsj_capitalization_punctuation: explicit complete-sentence whitelist + soft-flag pattern for Rule 5 price formatting (price_spacing_correct / price_bolded_correct accept needs_manual_check, new price_formatting_caveat field)
- wsj_typography_hierarchy: graphic/illustrative headline awareness — large stylised serif price/number graphics are recognised as the display headline; surrounding sans-serif copy is correctly classified as subhead/body. Stylised price headlines exempt from the period rule.
- wsj_logo_compliance: horizontal logo placement allows anchoring to the copy block on split/asymmetric layouts; mandatory sizing assessment block with worked examples, score capped at 6/10 for logos exceeding 30% of longest side.
Validated on 3 WSJ-NY test assets across 3 iterations.

Three rounds of prompt tuning against the Remington (4p), Easter Overlay
(18p), and Grenade (7p) sample packs. Easter Overlay (the noisiest)
climbed 72.38 → 78.97 → 80.04 across iterations, with strict-grade
violations dropping 27 → 18 → 14. Remaining violations are now genuine
compliance issues — the noise patterns are cleared.
boots_caveat_compliance:
- Superscript guard: vision LLM was flagging every roundel asterisk as
superscript because the * glyph naturally sits high in its line.
Strict two-feature rule now required (raised baseline AND visibly
shrunk ~50-60% of body). Borderline cases → "needs_manual_check"
with new superscript_caveat field. Caveat avg 4.4 → 7.27.
- Same vision-LLM caveat applied to weight_matching (Light vs Regular
at small sizes is below detection threshold) and sizing_compliant
(1-2pt size differences below detection threshold). New weight_caveat
and sizing_caveat fields. Reserved 1-2 score band for unambiguous
critical violations only.
- Explicit scoring principle: "when in doubt, prefer 7-8 with
manual_check flags over a lower confident-violation score".
boots_brand_name_accuracy:
- ALL CAPS retail convention now explicitly acceptable. L'OREAL,
ESTEE LAUDER, MAYBELLINE etc. no longer flagged as casing errors —
only structural element mismatches (accents, hyphens, apostrophes,
special chars) count.
- Stylised brand logotype exception: known logomarks like `17` for
SEVENTEEN, &SISTERS ampersand styling, e.l.f. dot rendering are
Pass — surfaced via new logotype_observations field.
- Brand name avg 5.53 → 7.47 → 6.67 (LLM run-to-run variability).
Strongest real catch in dataset: Easter Overlay page 14 is labelled
for the ROI market in production notes but uses £ instead of € on
the artwork. Exactly the pre-press error worth surfacing. Caught
consistently across all runs by boots_currency_locale.
CLAUDE_BOOTS.md updated with three-pack smoke-test table, vision-LLM
limitations summary, and the four reusable prompt-tuning patterns
that worked on this build.
Local-only — feature/boots-ppack remains unmerged until after Boots
show-and-tell.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

Fixes based on testing 12 WSJ subscription campaign assets across 4
concepts and multiple formats (320x50 to 1080x1920):
- wsj_color_usage: Clarify Pop-on-Jewel is the primary approved
combination, not a tier-mixing violation
- wsj_logo_compliance: Marketing assets use 30% longest side rule
(not 60% standalone rule); fix stacked logotype sizing too
- wsj_capitalization_punctuation: Add explicit decision tree for
Title Case vs Sentence Case — complete sentences use sentence case
- wsj_layout_composition: Add graphic/illustrative as valid design
variation; add format awareness for small banners
- wsj_imagery_expression: Broaden neutral category to explicitly
cover graphic/illustrative campaign assets
- wsj_typography_hierarchy: Add format awareness so small formats
aren't penalised for fewer hierarchy levels

LLM was autocompleting partial words and reading them as full text, missing
the hidden overlap. New approach: explicit "DO NOT AUTOCOMPLETE" instruction,
character-level boundary check (what background is each character on),
spatial proximity check (text touching product = fail regardless), and
concrete example using the actual test case ("para" where "p" is hidden
on dark purple product appears as "ara").
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds Step 4 (Hidden Overlap Detection) that catches text-product overlap
where text colour matches product colour, making overlapping letters
invisible. Instead of trying to see the hidden letter, the LLM detects
that a word is truncated/incomplete near the product edge, proving
overlap exists. E.g. "ragrância" instead of "Fragrância" where the
missing "F" is black on dark purple.

New boots_static profile (5 checks, 2.0 weight each) for retail promotional
artwork compliance: caveat rules, brand name accuracy (~170 names), offer
mechanics, T&C wording, and currency/locale. Strict grading override (any
check <6 = Fail). Guidelines embedded from 7 thematic guidance documents.
Also splits client-specific documentation out of CLAUDE.md into separate
CLAUDE_LOREAL.md, CLAUDE_AMAZON.md, CLAUDE_BOOTS.md, and CLAUDE_DOW_JONES.md
files to reduce main file size.

Callout text was fully exempt from overlap checks, so the perfume
image text crammed against the product scored 10/10. Now callouts
are still checked for direct spatial overlap — being near the product
in clean space is OK (shampoo), but overlapping or touching the
product imagery is still a fail (perfume). Only the headline width
check (Step 4) remains display-text-only.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Marketing copy near the product was being misclassified as exempt
callout text. Now callout exemption requires a visible connector/
pointer line drawn from the text to a product feature. Text without
a connector line is always classified as display text regardless
of size or proximity to the product.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Small feature callouts with connector lines (e.g. "Plástico
reciclado" pointing to bottle cap) are standard cosmetics layout,
not an overlap problem. Shampoo image was false-positive failing
because callout text near the product was flagged.
Now classifies text as DISPLAY (headlines, titles, body — checked
strictly) vs CALLOUT (feature annotations with pointer lines —
exempt). Only display text triggers overlap failures.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
LLM kept passing the mask image because headline is technically
above the densest part of the translucent shape. Added Step 4
(Headline Width Check) that catches wide single-line headlines
extending across the product's horizontal space — even if vertically
above. Includes exact bad/good examples matching the L'Oreal
mask vs shampoo assets.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Shampoo image was incorrectly failing because:
1. Thin connector/callout lines (pointing from text to product features)
were being treated as text overlap — now explicitly excluded
2. Hero zone was too wide — small scattered droplets/bubbles were
extending the zone to cover the full image. Now clarified that
hero zone is the compact cluster around the product only.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Revert text_readability to original (overlap is a layout issue, not a
readability one — LLM kept scoring it Pass because text was readable).
New text_product_overlap check uses a step-by-step approach:
1. Define the product hero zone (including translucent/glass elements)
2. Identify all marketing text
3. Check spatial overlap between text and hero zone
4. Compare good vs bad layout patterns
L'Oreal Static profile now has 4 checks at 2.5 weight each (was 3
checks at 3.33). Total check count: 66.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
LLM was still dismissing translucent 3D shapes as background. Rewrote
the check as a 3-step process (define hero zone, check overlap, score)
with explicit warning not to dismiss transparent elements. Added
concrete example matching the L'Oreal Absolut Repair Molecular mask
asset where the headline crosses the translucent sculpted shape.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
LLM was not recognising translucent/glass decorative elements around
products as part of the product area. Expanded the definition to
explicitly include semi-transparent shapes, artistic renders, and
silhouettes. Added boundary-drawing instruction and concrete
pass/fail examples matching L'Oreal Absolut Repair Molecular assets.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds critical check for marketing text overlapping product or product
packaging (e.g., translucent containers, decorative elements). Text
overlapping product area caps score at 4-5/10, triggering Fail under
L'Oreal's strict grading override.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The prompt was too aggressive about light products on light backgrounds,
causing professional product photography on white backgrounds to fail
(e.g. L'Oreal cream jar on white). Now evaluates whether the product
is actually VISIBLE and DISTINGUISHABLE (via shadows, edges, texture,
contrasting elements) rather than failing on theoretical colour match.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- File queue: add text-overflow ellipsis, min-width:0, flex-shrink:0 to
prevent long filenames from pushing Pending/Remove buttons out of view
- text_readability: product-only images (no marketing text layout) now
score 7/10 neutral instead of 1-2/10 critical fail. Hidden/invisible
text in marketing layouts still scores 1-2.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
New client with embedded brand guidelines for Dow Jones Corporate,
MarketWatch, and Wall Street Journal sub-brands. Guidelines sourced
from live.standards.site scrapes and baked into check prompts.
- dow_jones_static: 5 checks (logo, color, typography, square motif, photography)
- marketwatch_static: 6 checks (logo, color, typography, image treatment, layout, art direction)
- wsj_static: 6 checks (logo, color tiers, typography, imagery, capitalization, layout)
- System now has 7 clients, 12 profiles, 65 QC checks
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
OCR measurements were causing the LLM to over-rely on bounding box numbers
and fail correct assets on minor measurement inaccuracies. Changes:
- All prompts now say "supplementary data" not "authoritative/primary source"
- LLM instructed to prioritise visual assessment, use OCR to confirm/question
- Alignment tolerance widened from 1.5% to 3% of width
- OCR context footer softened with accuracy caveat (~5-10px margin of error)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds Tesseract-based OCR pre-processing that computes pixel-level text
positions, margins, spacing, and alignment before LLM analysis. This
enables detection of subtle layout differences that vision models miss
(e.g. 2.8% vs 6.4% headline margin, 83px vs 39px date gap).
OCR measurements injected into 10 checks across all client profiles:
- Amazon: margins, typography, headline_layout
- Static General: element_alignment, safety_area, visual_hierarchy_general,
text_readability_general, text_edge_clearance
- L'Oreal: text_readability
- Diageo/Unilever KV: visual_hierarchy
Non-blocking: if Tesseract is unavailable, checks run with visual
estimation only. Production requires: sudo apt install tesseract-ocr
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add silent auth check every 5 minutes to detect expired sessions proactively,
showing a "Session Expired" prompt instead of failing silently on next action
- Rename amazon_box_placement to amazon_element_placement across module directory,
profile config, class name, and documentation
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Typography: soften date spacing rule for tall/portrait formats (half cap-height OK)
to fix false positive on DE_Ströer correct file
- Margins: add percentage-based gap estimation to force LLMs to quantify left alignment
differences, improving detection of subtle headline oversizing (IE_BrightSide case)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Box placement: tape cut off by asset edge is now a fail (was passing if tape visible on other edges)
- Margins: left alignment consistency elevated to critical check with step-by-step comparison method
- Typography: headline-to-date spacing uses cap-height reference instead of lenient "only if clearly too tight"
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Fix process queue bug: reset queue items to pending after completion so
reprocessing works without page refresh
- Show report details for 10/10 scores by extracting explanation and
elements_found fields from Amazon check JSON responses, with a fallback
that renders all JSON data as a structured summary
- Add Amazon Static grade override: any individual check scoring below 6
forces overall grade to Fail (same logic as L'Oreal)
- Box placement prompt: relax tape visibility rule from "all edges" to
"at least one edge visible", prevent false positives on landscape formats
where box sits near right edge
- Headline layout prompt: fix LLM misreading one-word-per-line as combined
lines in tall/portrait formats, score multi-sentence headlines in 9:16
as 6/10 (pass with recommendation) instead of fail
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Reverted loreal_static from 2-check (visual_readability_contrast) to
3-check setup (language_consistency, text_readability, background_contrast)
to avoid score dilution. Updated text_readability and background_contrast
prompts from POS-focused to digital marketing, and added critical hidden/
invisible text detection (black-on-black, white-on-white scanning).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Headline layout: prepositions at end of line (di, of, de) are now
acceptable in display typography. Tall format one-word-per-line is
standard. Only fail for sentence endings mid-line or genuinely
confusing breaks.
Typography: spacing check now only flags genuinely cramped/touching
elements, not moderate gaps that provide visible separation.
Box placement: improved tape description to match actual campaign
assets (branded coloured strips on box edges, not plain packing tape).
Only flag tape as missing if cropped by asset edge or genuinely absent.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The margins check was giving 10/10 when headline text was too close to
the left edge and misaligned with the logo/branding below. Added left
alignment consistency section checking that headline, date, and logo
share the same left margin position, with misalignment flagged as a
margin/sizing issue.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The typography check was giving 10/10 when the date text was squeezed
up against the headline with no breathing room. Added explicit element
spacing assessment section with guidance that the gap between headline
and next element should be at least the height of a capital letter in
the date text, and included it in evaluation steps and output JSON.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The LLM was giving 10/10 Pass to boxes with tape completely cut off,
treating aggressive right-side crops as acceptable. Added explicit
step-by-step tape visibility checks, clarified that right-side crop
must not remove tape/flaps, and added guidance to not assume tape is
visible just because the box body is present.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adjusted all 6 Amazon check weights to equal 1.67 each based on test
results showing incorrect scoring. Refined prompts for box placement
(format-aware positioning, better tape description), required elements
(subhead now optional for OOH), logo country (country match as primary
factor), margins (visual assessment over pixel estimates), and headline
layout (natural language break detection, tall format awareness).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add Boots client with static_general profile and Amazon client with
6 new brand-specific QC checks based on ASD 2025 design guidelines:
