HTTPS enforced sitewide + HSTS (≥ 6-month max-age)https-and-hsts-enforcedHSTS

Enforce HTTPS sitewide and ship a Strict-Transport-Security header with max-age ≥ 6 months

Why this matters: AI agents and payment flows refuse plain HTTP; weak HSTS is treated as effectively no HSTS by trust-and-safety scanners.

RFC 6797 — HTTP Strict Transport Security (HSTS)

−2.9impact

Findings (1)

Confirmed the homepage is HTTPS (status 200), probed http://lepetitballon.com/ for redirect behaviour, and parsed the Strict-Transport-Security header (value: "max-age=7889238").

How: URL scheme + homepage status check, an http://host/ redirect probe through politeFetch, and a Strict-Transport-Security max-age parse (RFC 6797; ≥ 180-day threshold).

HSTS max-age is below the 6-month minimumCRITICAL
/parsed max-age = 7889238s (need ≥ 15552000s = 180 days)
What we found
```
max-age=7889238
```
What we expected
```
Strict-Transport-Security: max-age=31536000; includeSubDomains
```
Bump max-age to at least 15552000 (180 days). 31536000 (1 year) is required for preload-list inclusion.

GTIN coverage on PDPsproduct-gtin-populatedSchema.orgMerchant

Populate gtin on every branded Product node

Why this matters: GTINs let agents match your product to the same item elsewhere; without them you lose cross-catalog matching.

schema.org/Product.gtin

−1.9impact

Findings (11)

Checked 20 sampled product pages for a GTIN in the Product JSON-LD (1 carry a valid GTIN, 5%).

How: Extract gtin / gtin8 / gtin12 / gtin13 / gtin14 from the first Product JSON-LD node on each PDP; validate digit length.

Offer JSON-LD carries shippingDetails (OfferShippingDetails)offer-shipping-details-presentSchema.orgShipping

Emit shippingDetails (OfferShippingDetails) on Offer JSON-LD

Why this matters: Without shippingDetails, AI agents fall back to vague defaults — they can't quote your rates, destinations, or delivery windows in shopping cards.

schema.org/OfferShippingDetails

−1.7impact

Findings (11)

Inspected shippingDetails on Product/Offer JSON-LD across 20 sampled PDPs (0 present, 0%).

UCP profile carries all four required top-level keysucp-profile-required-keysUCP

Add every required top-level key to the UCP profile

Why this matters: A profile missing one of the four required keys is treated as non-conformant — agent runtimes fall back to default behaviour and may skip the merchant.

UCP overview — required profile keys

−1.6impact

Findings (1)

Profile is missing required key(s): signing_keys.

How: Read the profile root (or top-level ucp wrapper) and verify the presence of version, services, capabilities, and signing_keys keys.

Findings (4)

Read the image field on Product JSON-LD across 20 sampled product pages (16 resolve at least one URL, 80%).

UCP profile Cache-Control is shared-cacheable with max-age ≥ 60sucp-cache-headers-validUCP

Skipped — the runner did not surface transport metadata

Context: If your UCP profile says `no-cache`, agent runtimes re-fetch on every interaction — brittle at scale and prone to rate-limit failures.

UCP overview — profile caching

Not scoredimpact

Why this was skipped

Wanted to inspect the UCP profile's Cache-Control header, but the runner did not surface transport metadata.

How: Parse the Cache-Control header on the /.well-known/ucp response; require public, max-age ≥ 60, and no no-store/no-cache/private.

Transport metadata not available — runner update pendingLOW
/.well-known/ucp
This check activates once the runner (Task I1) populates ctx.wellKnownUcp.cacheControl.

NAHIGH

Every signing_keys[] entry is a valid JWKucp-signing-keys-validJWKS

Skipped — Profile declares no signing_keys; JWK validation has no entries to evaluate.

Context: Malformed JWK entries are rejected silently by agents — signed payloads cannot be verified and the merchant loses trust signal.

RFC 7517 — JSON Web Key (JWK)

Not scoredimpact

Why this was skipped

Profile declares no signing_keys; JWK validation has no entries to evaluate.

How: Walk signing_keys[] and validate each entry per RFC 7517 §4.1 (kty required) + RFC 7518 §6 (kty-specific required parameters). kid is OPTIONAL per RFC 7517 §4.5 and not enforced here.

HSTS policy carries the includeSubDomains directivehsts-include-subdomainsHSTS

Add includeSubDomains to your Strict-Transport-Security header

Why this matters: Without includeSubDomains, an HTTP subdomain (staging, mail, …) can be used to attack the apex's cookies.

RFC 6797 — HSTS `includeSubDomains` directive

−1.1impact

Findings (1)

Inspected the homepage Strict-Transport-Security header ("max-age=7889238") and the includeSubDomains directive is absent.

MerchantReturnPolicy merchantReturnLink URL is reachablemerchant-return-link-reachableReturns

Skipped — No MerchantReturnPolicy node carried a `merchantReturnLink` URL, so reachability has nothing to evaluate.

Context: A broken return-link makes Option B policies invisible — agents can't render or follow the link.

Google return-policy SD — merchantReturnLink reachability

Not scoredimpact

Why this was skipped

No MerchantReturnPolicy node carried a merchantReturnLink URL, so reachability has nothing to evaluate.

How: Collect every unique merchantReturnLink URL across all MerchantReturnPolicy nodes; probe each once via politeFetch (failSoft). 2xx counts as reachable.

NAMEDIUM

OfferShippingDetails shippingDestination is a valid DefinedRegionoffer-shipping-destination-validShipping

Skipped — No OfferShippingDetails node carried `shippingDestination`, so the DefinedRegion check has nothing to evaluate.

Context: Without a valid destination region, your shipping rate has no scope — Google can't decide whether to render it for a given shopper's country.

Google shipping-policy SD — shippingDestination as DefinedRegion

Not scoredimpact

Why this was skipped

No OfferShippingDetails node carried shippingDestination, so the DefinedRegion check has nothing to evaluate.

How: On each OfferShippingDetails node where shippingDestination is set, require it to be a DefinedRegion (or array) and every entry to carry addressCountry matching /^[A-Z]{2}$/i.

NAMEDIUM

OfferShippingDetails shippingRate is a valid MonetaryAmountoffer-shipping-rate-validShipping

Skipped — No OfferShippingDetails node carried `shippingRate`, so the MonetaryAmount check has nothing to evaluate.

Context: An invalid rate object is silently dropped; agents can't quote your shipping cost in shopping cards.

Google shipping-policy SD — shippingRate as MonetaryAmount

Not scoredimpact

Why this was skipped

No OfferShippingDetails node carried shippingRate, so the MonetaryAmount check has nothing to evaluate.

How: On each OfferShippingDetails node where shippingRate is set, require an object with numeric value/maxValue (typed or numeric string) and a 3-letter ISO 4217 currency.

Context: Capabilities missing version/spec/schema can't be matched against agent support tables — agents skip them silently.

Why this was skipped

Profile declares no capabilities; required-field checks have nothing to evaluate.

How: For each capabilities[] entry, require non-empty string values for version, spec, and schema.
