Your first Zambo run: What actually happened (vs. what you hoped for)\n\nYou asked for source-backed prospects in Austin for web design. The tool returned zero results.\n\nThat is not a failure; it is a data point. The LeadSignal tool scanned the current free tier database for your specific query and found no matches. It did not guess. It did not hallucinate a list of names to please you. It reported the truth: right now, there are no source-backed leads in that specific pocket for that specific service on the free plan.\n\nThis is the core of Zambo’s value proposition. We do not hide behind \"I hope this helps.\" We provide receipts.\n\nThe receipt for that search is here: https://zambo.dev/run/1cea9031-c6e0-4fac-8075-f35d29594de3\n\nClick it. You will see the query, the tool used, the zero count, and the exact timestamp. This link is your proof that the system functioned as designed, even when the design yielded an empty set. A receipt proves the bytes saved; it does not prove the market is saturated, only that your current parameters returned nothing.\n\nYour next step is not to demand a list. It is to widen the net.\n\n1.  **Change the City:** Try Dallas or Houston.\n2.  **Change the Service:** Broaden \"web design\" to \"digital marketing\" or \"local SEO.\"\n3.  **Check Your Quota:** You have 3 free LeadSignal calls remaining on this tier. You do not want to waste them on narrow, high-probability-of-zero queries.\n\nZambo works with your host AI, not instead of it. It gives you the concrete route. If the route leads to a dead end, the tool tells you so immediately, saving you hours of manual searching that would have led to the same empty folder.\n\nStop guessing. Start verifying.\n\n**Your move:** Pick a broader city/service combo. Run the search. Share the new receipt. If you find a lead, we’ll talk about how to convert it. If you don’t, we’ll adjust the strategy.\n\nNo fluff. Just data.\n\n[Your Name]\n[Your Title]\n[Company Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:67356afa18a664bab959b08c640ce5b61d3dbcd4ee2f81cb5b935207d04b9fbc","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:ba37de193f8915856b22d27812cd5f89b2131c34db86472c2b55b0bba318772c","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:043858d1a0c6902355dce1e06dcb48a45ddfea60e0ab4a38c98bb04a9916b700","anchor":{"event_id":"e317c204743526a87d3805133e38d36e8fd27a7e30930529083c068b3a7af62a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-30T15:40:41.264Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-30T15:40:40.695Z","evidence_url":null,"receipt_uuid":"537eb5b4-cbce-4b35-891f-c3cc3c77e461","output_sha256":"sha256:6d7d98382ffcbe81390ed9ea2a65eface7cc3add67c9848328aaf03d743906c6","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-30T15:40:40.695Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:6d7d98382ffcbe81390ed9ea2a65eface7cc3add67c9848328aaf03d743906c6\",\"receipt_uuid\":\"537eb5b4-cbce-4b35-891f-c3cc3c77e461\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-30T15:40:40.695Z","detail":"The receipt store reports 2026-10-30T15:40:40.695Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
