Evidenced brief · 4 findings · credit-first
The highest $/tonne deal in Frontier's book, two distinct but equally honest 404 responders, no agent manifest, and the field-labor angle around a limestone site.
No jargon. Heirloom's record is real and credited below; the one fresh gap is worth naming plainly — here's what closing it is worth.
Only a 51-byte robots.txt is published for agents today, so an assistant asked who delivers durable DAC at Heirloom's quality has no machine-legible surface and paraphrases scraped pages instead of Heirloom's own record and its Frontier offtake.
Credit-first: real capability and honesty are named before any gap. Every claim below carries a plain reverify command — run it yourself.
$26.6M for 26,900 tonnes by 2030, an implied $989/tonne, announced Nov 2023 (2023 vintage): the single priciest ton among all 18 named Frontier offtakes reviewed in EcoWealth's own recon.

curl -s -o /dev/null -w "%{http_code}:%{size_download}\n" https://www.heirloomcarbon.com/robots.txtTray spreading/turning, sampling support, and site restoration are bounded, repeatable field tasks around the plant: the exact shape EWP packet-prices (fund→claim→prove→settle), distinct from the calcination chemistry itself.
internal working notes: EWP's fund/claim/prove/settle packet lifecycleHeirloom does not need EcoWealth; nothing here claims a relationship, a gap in their operations, or a pitch. What follows is a concept: the bounded, photo+GPS+signature-proven field tasks EWP already prices per-packet, mapped onto the kind of physical plant/field work a limestone DAC operation runs day to day.
Concept only: not a proposal to Heirloom, not a claim they lack this capability internally, and not evidence any EWP packet has ever been posted for this pathway. EWP's own proof (photo+GPS+one-time signature) is a task-completion layer, not a carbon-quantification or registry-issuance layer: durable-CDR crediting requires accredited MRV far heavier than a single field packet, as EcoWealth's own Carbonfuture recon (2026-07-16) already found in detail.
