Release claims, with receipts.
We sell cryptographic receipts for agent work, so our own release claims come with them. Every entry below is committed to the log.traceseal.io transparency log, whose checkpoints are cosigned by an independent witness. Don't take our word for any of it.

One script checks the full chain: entry hashes, the RFC 6962 Merkle root, the log's Ed25519 checkpoint signature, and the witness cosignature — then any single receipt against its log entry. Download it, read it (it's ~230 lines), then run it:
curl -sO https://traceseal.io/changelog/verify.py $ python3 verify.py # the whole log, checkpoint and witness $ python3 verify.py 24 # plus the receipt for entry 24

Alibi repo: python3 -m lib.tlog_witness
Independent verifier for the witnessed log
lib/tlog_witness.py shipped in the open-source Alibi repository: a standalone verifier for the log's signed checkpoint and the witness cosignature/v1, pinned to both public keys. Commit 9aee9fb.
The log gains an independent witness
witness.markovianprotocol.com (Markovian Protocol) pinned our log key and now cosigns log.traceseal.io checkpoints after verifying each new tree is an append-only extension of everything it previously cosigned. First cosignature: 2026-08-17T14:17:40Z. From this point the log cannot show different readers different histories without the split view becoming provable.
Signed checkpoint endpoint
The transparency log publishes a signed c2sp.org/tlog-checkpoint note at log.traceseal.io/checkpoint. Leaves are the raw lines of the published entries.jsonl (RFC 6962), so anyone can recompute the tree root from public data alone.
Security-hardening releases: traceseal-verify 1.0.2, traceseal-observe 1.3.2
Both packages republished to PyPI resolving the four HIGH findings of the 2026-06-07 security audit: manifest omission not detected and unbounded signature input (verify); unbundle returning an unverified payload and error messages that could leak credentials (observe). Wheel and sdist digests are pinned in the receipts. These releases predate the log, so their receipts were logged retrospectively on 18 August 2026 — the receipt states both dates.
Transparency log genesis
The first 19 entries of the log: signed publication receipts for agent skills, hash-chained back to genesis. These entries are their own receipt — they are the leaves the signed checkpoint commits to.
