Shipped key_source ∈ {inline, cache, resolver} as a signed field in the composition-ref spec (commit 819f84d) — makes key resolution strategy auditable across the receipt's lifetime, not just at verification time. First independent cross-trail completed: Talos/konstantinos193 verified used(ref)==true on their own stack against the same action_ref hash (byte-identical, no shared code). Anchored on Arb Sepolia, tx 0x4d8edc46bf039c52fa57c3c42e6af3a1e04fdbe55c2f47e4c02adbcea5a10fba. This is the first external verifier confirming the trail independently — zero operator trust required.

Bootstrapped. No external funding to date. Revenue model: pay-per-trail ($0.003/trail) with enterprise tier. First integrators active.
