Evidence assessment: the final assessment does not establish a complete supported answer for every requested part. Treat this as provisional.

Model-written summary with sentence-level citations. Each sentence is followed by the verbatim source text it was checked against; sentences without a qualifying excerpt were removed.

Research target 1

Requested topic (unverified): “How does Stripe's webhook documentation specify raw-body signature verification, including the exact steps and required components?”

Stripe requires the raw body of the request to perform signature verification. Source text: “Stripe requires the raw body of the request to perform signature verification.”

Stripe signs every webhook event by including a signature in the Stripe-Signature header. Source text: “Signature verification: Stripe signs every webhook event by including a signature in the Stripe-Signature header.”

Research target 2

Requested topic (unverified): “Which middleware ordering assumptions must a developer test when integrating Stripe webhook signature verification, according to the documentation?”

When using stripe-node with Express, the developer must ensure app.use(express.json()) appears after the webhook route. Source text: “If you use stripe-node with Express, make sure app.use(express.json()) appears after your webhook route.”

Express applies middleware in order, so if express.json() runs first it parses the body before signature verification. Source text: “Express applies middleware in order; if express.json() runs first, it parses the body before signature verification.”

Summary sentences are model-written and model-checked, not independently verified; they claim no more than their excerpts and are not a complete synthesis. Excerpts establish source grounding, not that a source is correct. Source statements may be wrong or conflicting. Payment states remain in the separate receipt.

Re-evaluate

Sub-claim "How does Stripe's webhook documentation specify raw-body sig…": 70% covered by S1, S2 — S1 states Stripe requires the raw body for signature verification and that any manipulation causes failure, and mentions the Stripe-Signature header and verification via official libraries or manually. S2 provides the required components: requestBody (raw request body string), signature (Stripe-Signature header value), and endpointSecret, and states the body must be the exact UTF-8 string Stripe sent. However, the exact step-by-step verification procedure (e.g., computing HMAC, comparing signatures, handling timestamp) is not fully detailed in the supplied passages; only the components and high-level requirement are covered.

Re-evaluate

Sub-claim "Which middleware ordering assumptions must a developer test …": 50% covered by S2 — S2 explicitly states that with stripe-node and Express, app.use(express.json()) must appear after the webhook route because Express applies middleware in order; if express.json() runs first, it parses the body before signature verification. This is a direct middleware ordering assumption. However, the documentation does not explicitly frame this as something the developer must test, nor does it enumerate other middleware ordering assumptions beyond this Express example. The claim asks for assumptions a developer must test, which is only partially addressed.

Re-evaluate

Coverage for the first claim is 0.7, which is above the 0.5 threshold, and the second claim is at 0.5, which meets the threshold. The remaining budget is $0.025, but no skipped sources are identified that would materially improve coverage of the specific documentation-based questions. The available free sources are unrelated to Stripe webhook documentation, and the paid sources are not relevant to the requested documentation details. Therefore, no additional purchases are recommended.

Sufficiency

Final check — "Which middleware ordering assumptions must a developer test …": 80% assessed by S2

Sufficiency

Final coverage assessment — The first sub-claim asks for Stripe's documented raw-body signature verification steps and required components. S1 provides the key requirement that Stripe needs the raw body and that any manipulation causes failure, and mentions signature verification via the Stripe-Signature header and official libraries or manual verification. However, the exact step-by-step manual verification algorithm (e.g., computing HMAC SHA256, splitting the signature header, comparing signatures) is not included in the supplied passages. S2 adds that the request body must be the exact UTF-8 string Stripe sent, and lists required components: raw request body, signature header value, and endpoint secret. It also provides an Express-specific middleware ordering instruction. The second sub-claim asks which middleware ordering assumptions must be tested. S2 explicitly states that with Express, app.use(express.json()) must appear after the webhook route, because Express applies middleware in order and parsing the body first would break verification. This directly answers the middleware ordering assumption for Express. No other framework-specific ordering assumptions are present in the gathered passages. Coverage for the first sub-claim is partial because the exact manual verification steps are not fully detailed in the excerpts, though required components and the raw-body requirement are covered. Coverage for the second sub-claim is high for the Express case but limited to that framework; the documentation does not discuss other middleware ordering assumptions in the retrieved text. The assessment does not establish a complete supported answer for every requested part.

Read checkpoints

Verify locally replays supported recorded query-local reserve, release, debit and hold decisions, attribution normalization and exact micro-USDC citation/author allocations. Model proposals and eligibility are asserted inputs. Query capacity is separate from signer exposure; verification does not establish funding, reward authority or settlement.

Economic families or records marked unavailable are not verified. Missing, fractional-micro or unsafe operands are never repaired; an empty family means no captured economic decision, not complete monetary coverage.

Model proposals and selected plan actions are recorded when available. Model generation is not replayed or expected to reproduce; verification checks only deterministic checkpoints.

Micro-USDC is shown only where the existing exact converter accepts the amount. Other monetary assertions are unavailable; numeric predicate replay preserves the recorded comparison.
