Evidence

Signed projection - frozen historical calibration record

Signed by the producer and verified here against the configured public key. That check proves these exact bytes are unchanged since signing. It does not prove key provenance beyond this site's configuration, an independent audit of the run, or a re-run of the evaluation - it is a calibration summary frozen on September 11, 2026. Anything missing or invalid renders as unavailable, never as a claim. The static snapshots below remain the reported historical record.

Verify this projection yourself

The projection above is data, not a screenshot. Download it, recompute its digest, and check the signature yourself against the projection public key this site is configured to trust. You need jq, sha256sum and openssl - preinstalled or a package on any macOS or Linux box.

Projection: signed-projection-2026-09-11.json

# Save the projection (also linked above)
curl -sSLO https://madebyapex.dev/evidence/signed-projection-2026-09-11.json

# Recompute the evidence digest: canonical JSON (keys sorted, no
# whitespace) with the signature and evidenceDigest fields removed.
# The result must equal the evidenceDigest field.
jq -cjS 'del(.signature, .evidenceDigest)' signed-projection-2026-09-11.json | sha256sum
jq -r .evidenceDigest signed-projection-2026-09-11.json

# Verify the Ed25519 signature over the signed bytes: canonical JSON
# with only the signature field removed.
jq -cjS 'del(.signature)' signed-projection-2026-09-11.json > canonical.json
jq -r .signature signed-projection-2026-09-11.json | base64 --decode > signature.bin

# Expected: Signature Verified Successfully

What this proves: these exact bytes were signed by the holder of the projection private key this site is configured to trust, and the recomputed digest is the key under which this site files the projection against its receipt record - so the filing provably covers these exact bytes. What it does not prove: key provenance beyond this site's configuration, an independent audit of the run, or the receipt itself. It does not re-run the evaluation. Fresh-clone replay is reported in a separate private account, and this projection is a signed calibration-lane summary, frozen historical. The development-only primary receipts, mirrors and replay tooling are not publicly accessible; access requires separate authorization.

Downloads - take the record with you

The public signed projection, verifier and annotated explanation are downloadable. The underlying governed receipts and mirror remain private, not publicly accessible; access requires separate authorization.

• The offline verifier kit - a single file that recomputes the evidence digest and checks the Ed25519 signature with the published projection key. Runs entirely in your browser, works offline, sends nothing anywhere. Check the published summary yourself; this does not verify the private primary receipts.
• The annotated summary - an annotated explanation of the signed fields and intended workflow, including the reported 26,854-test PASS. It is not an authenticated chronology or a replay of private stage receipts.
• The signed projection itself - the frozen calibration record as raw JSON. Feed it to the verifier kit, or to your own tooling.
• Reproduce the check with Node or download the kit. The zip holds the offline verifier, this signed projection, the pinned public key, and a README. Node only. No network.
