Breaking down: "How does Keryx Engineering's documented paid research job recovery bind a buyer's approved purchase to its exact job, resource and execution, and preserve it across delayed execution, pending settlement and retries? Compare its documented exact purchase journal and recovery semantics with approval/action binding and retry hazards. Inspect the source-owned Recovering a Keryx paid research job article, distinguish first-party documented behavior from independent safety evidence, and state unsupported dimensions rather than infer them."

Sub-claim "How does Keryx Engineering's documented paid research job re…": 10% covered — No gathered passage documents Keryx's binding of an approved purchase to an exact job, resource, or execution. The only Keryx-related gathered item is the Privacy page preview, which mentions local recovery files containing the question and payment signature and that importing does not send a new payment, but it does not describe job/resource/execution binding. The source-owned 'Recovering a Keryx paid research job' article was skipped and only its title/preview is available, which is insufficient to answer this sub-claim.

Sub-claim "How does the documented recovery preserve that binding acros…": 10% covered — No gathered passage documents Keryx's preservation of purchase-to-job binding across delayed execution, pending settlement, or retries. Generic passages from S1 (Make incomplete executions) and S2 (Effect Agent durability) discuss retry/incomplete-execution concepts but are not Keryx documentation and do not address Keryx's binding semantics. The Keryx Privacy preview only notes that importing a recovery file saves a local copy and does not send a new payment, which is topical context but not an answer.

Sub-claim "What does the source-owned 'Recovering a Keryx paid research…": 10% covered — The source-owned article was skipped; only its title and a one-line preview are available ('How Keryx buyers quote, journal a purchase and resume the original job without signing a second payment'). That preview is topical context but does not document exact purchase journal semantics, recovery semantics, approval/action binding, or retry hazards. No gathered passage supplies the article's content.

Sub-claim "Which dimensions of this binding and recovery are unsupporte…": 10% covered — Because the first-party Keryx recovery article was not read and no independent safety evidence about Keryx recovery was gathered, the set of unsupported dimensions cannot be established from the supplied passages. Generic retry-hazard passages (S1, S2) are not Keryx-specific and cannot ground a claim about which Keryx dimensions lack first-party or independent support.

All four sub-claims are at 0.1 coverage because the source-owned 'Recovering a Keryx paid research job' article was skipped and no gathered passage documents Keryx's purchase-to-job/resource/execution binding, its preservation across delayed execution, pending settlement and retries, its exact purchase journal semantics, or which dimensions lack first-party/independent support. The only affordable skipped source that directly targets the question is the Keryx Engineering first-party article at $0.002, which fits the remaining $0.025 budget. Other skipped sources are either off-topic (Keryx Biopharmaceuticals, construction rework, gardening, retro hardware) or generic durability/retry material that does not answer the Keryx-specific sub-claims. Buying the Keryx article is the highest-priority and only clearly relevant purchase.

Final coverage assessment — The first-party Keryx article (S3) is the only source that directly addresses the requested Keryx paid research job recovery. It documents that buy obtains a fresh quote, rechecks payment policy, writes a durable job journal, signs once and submits once, and that each purchase needs a new private job directory. It also documents receipt snapshots archived by digest, seller-reported settlement, separation of payment evidence and content delivery, and that creator amounts may be settled, pending or unknown. However, the supplied passages do not document how the journal binds the approved purchase to an exact job, resource and execution, nor how that binding is preserved across delayed execution, pending settlement and retries. S1 and S2 are independent general references about incomplete executions, retries, durable execution and recovery, but they are not Keryx-specific and do not document Keryx's exact purchase journal or recovery semantics. Thus the Keryx-specific binding and retry-preservation dimensions remain unsupported by the supplied first-party text, and independent safety evidence for Keryx is absent. The assessment does not establish a complete supported answer for every requested part.
