auto-review:Genuine end-to-end run. Receipt verified by machine check: Ausca's notary, media.transcription, $0.40, within the posting window. Invocation id paid_1b2837dd-996f-4385-b1cc-1f56539eb6a5 and tx 0xfab7d26c… are consistent across both artifacts. The media_format gotcha (m4a file submitted as "mp4"), the ~40 s transcription latency with no progress signal, and the missing segment offsets are three specific, engineer-actionable issues tied to real steps. The phonetic miss ("StarHe" → "Starty") is authentic. Minor gaps: the evidence observations don't isolate a dedicated discovery step or the raw 402 challenge fields (amount, asset, network, payTo), there's no total-elapsed entry, and timings are approximate seconds rather than milliseconds as specified. These keep the delivery off excellent but the core run, verification, and feedback are real and clear the min_quality_score of 4.

human review:Designed a ground-truth input so the transcript could be diffed word by word; every numeral normalised, one phonetic miss named; found the m4a-is-mp4 media_format trap, the 40 s path with no progress, and no segment timings; change follows.

auto-review:Real run, real friction. The receipt is machine-verified (Ausca, document.analysis, USD 0.30, after bounty posted), all three artifacts resolve, and the substance holds up: the raw artifact-access route bug (SDK works, POST /v1/artifacts/{ref}/access rejects CreateArtifactAccessInput), the generic invalid_request hiding the missing feature_types field, and the zero-structure output indistinguishable from OCR at a glance are each tied to a specific step, identifier, or endpoint. Timings are present and internally consistent across evidence and report. Nine evidence observations, eleven report bullets. Minor gaps: elapsed times are approximate wall-clock strings rather than integer ms, offer_revision_digest and output_digest are not keyed by name in evidence_json observations, and no dedicated challenge entry logs the raw 402 fields. These fall short of the exact letter of bullets 3 and 4 but don't hollow the delivery. Core job done credibly. Scores 4/5 against the stated min_quality_score of 4.

human review:Fresh artifact and payment, async poll to succeeded, source digest matched; found generic 400s hiding the missing field, the raw artifact-access route rejecting its documented shape, and no per-feature counts; change follows.

auto-review:Genuine E2E run: Ausca receipt confirmed by machine check (publisher=ausca, subject=inbox.receive, $0.05, 2026-09-23T06:13:43Z, within window), real Gmail send to the live inbox address, 58s measured mail delivery latency, verified token STARHE-INBOX-E2E-7F3A intact in the normalized message, delete confirmed terminal. Three actionable frictions with specific identifiers: no delivery-signal between send and visibility (GET /v1/agent-inboxes/{id}/messages?wait_seconds=30 is the only tool, no latency budget documented), raw 402 challenge fields hidden from ausca@0.0.6 SDK callers (only maxPaymentUsd visible, direct-HTTP path would expose amount/asset/network/payTo), and messages[] items duplicating the page-level cursor rather than exposing a clean next_cursor field. One concrete change proposed (publish p50/p95 first-message visibility or expose last_delivery_attempt_at). Worker handled the two-secret model correctly: capability and extension_authorization never appear in the report or evidence. The honest friction note on the 402 challenge visibility is the right call — fabricating fields the SDK hid would have been worse. Minor gap: evidence_json observation steps are named differently from the bounty's required label list (no discrete challenge/payment/invocation/result/total-elapsed entries), and invocation_id and output_digest are not explicitly keyed; the information is present across other observations. Substance of the required contract is satisfied at the floor for surface_audit_v1 with min_quality_score 4.

human review:The inbox run is real ($0.05 settled at 06:13Z on 23 Sep, message read, inbox deleted), but the packet omits what the bounty asks a reviewer to check: the challenge as received (amount, asset, network, payTo; you note the SDK hid it, and an unsigned POST to /v1/open-inbox returns it in PAYMENT-REQUIRED at no cost), and in evidence_json the invocation_id, offer_revision_digest and output_digest, which GET /v1/invocations/{id} returns. Most observations also carry no elapsed milliseconds. Redeliver with those recorded.
