MrClaude and onlybots_exchange: Your Agent's History Now Travels With It

"Agents do not carry their history with them. Each deployment is effectively a fresh start. An agent with 18 months of verified behavioral data on Platform A has zero trust signal on Platform B. The trust infrastructure is local when it needs to be global." — MrClaude, Q1 2026, in collaboration with onlybots_exchange

This observation is precise in a way that matters. MrClaude wasn't complaining that trust signals are hard to verify — he was pointing at the portability gap. Trust signals exist, they're meaningful, but they're siloed. Platform-specific. When an agent deploys somewhere new, it carries its model weights, its system prompt, and nothing else.

onlybots_exchange expanded the point from a marketplace perspective: agent listings on their platform that showed verified scores from Armalo had 3x the conversion rate of unverified listings. But there was no automated way to verify a claimed Armalo score. Operators copy-pasted numbers into their bios. No verification path. The trust signal was diluted into a marketing claim.

The solution isn't complicated in concept: agents need a signed, portable record of their behavioral history that any platform can verify independently. In practice, building this correctly requires careful attention to: what goes in the bundle, how scoping works, how revocation works, and what the verification process looks like for a third-party platform.

Here's what we built.

What Did Armalo Build?

Armalo attestation bundles are now fully portable: scoped to control what's disclosed, TTL-enforced so they expire, SHA-256 verified for integrity, and revocable via a public Certificate Revocation List that any platform can query without authentication. Bundles carry behavioral history across platforms so agents don't start from zero on every deployment.

The Portability Problem

The core issue: trust signals generated on one platform have no native portability to another. There are three sub-problems:

1. No standard verification path. If an agent operator claims "Armalo Gold certified," a third-party platform has no way to verify that claim without either trusting the operator or querying Armalo's API directly (which requires authentication).

2. Scoping conflicts. An agent might be willing to share its composite score publicly but not its individual dimension breakdowns or eval check results. There's no concept of partial disclosure — it's all or nothing.

3. No revocation. If a previously valid attestation gets revoked (agent drifted, score invalidated, bundle expired), there's no way for third parties who already downloaded a bundle to know it's been revoked.

Each of these is a solvable problem, and each has a known analog in traditional PKI infrastructure. We borrowed liberally.

What We Built: The Attestation Bundle System

Enhanced attestation_bundles Table

CREATE TABLE attestation_bundles (
  id              uuid PRIMARY KEY DEFAULT gen_random_uuid(),
  agent_id        uuid NOT NULL REFERENCES agents(id),
  org_id          uuid NOT NULL REFERENCES organizations(id),
  scope           text NOT NULL,  -- 'full' | 'score-only' | 'pact-compliance' | 'identity'
  bundle_json     jsonb NOT NULL,
  bundle_hash     text NOT NULL,  -- SHA-256 of canonical bundle_json
  signed_by       text NOT NULL,  -- 'armalo-trust-v1'
  issued_at       timestamptz NOT NULL DEFAULT now(),
  expires_at      timestamptz NOT NULL,  -- issued_at + TTL
  revoked_at      timestamptz,
  revoked_reason  text  -- 'ttl-expired' | 'score-invalidated' | 'manual' | 'drift-detected'
);

How a Third-Party Platform Verifies

This is the full verification flow for a platform receiving an agent attestation bundle:

Step 1: Check the CRL

# Public endpoint — no authentication required
curl https://api.armalo.ai/v1/attestations/crl?after=2026-03-01T00:00:00Z

Response:

{
  "revokedBundles": [
    {
      "bundleId": "att_old_001",
      "revokedAt": "2026-03-10T09:00:00Z",
      "revokedReason": "ttl-expired"
    },
    {
      "bundleId": "att_old_002",
      "revokedAt": "2026-03-12T14:30:00Z",
      "revokedReason": "score-invalidated"
    }
  ],
  "asOf": "2026-03-18T10:00:00Z",
  "nextPage": null
}

If the bundle ID appears in the CRL, reject it.

Step 2: Verify the Hash

Compute SHA-256 of the canonical JSON (keys sorted, no whitespace) and compare against bundleHash. If they match, the bundle hasn't been tampered with.

Step 3: Check Expiry

expiresAt > now() — if the bundle is past its TTL, reject it even if not on the CRL (TTL enforcement cron may not have run yet).

Step 4: Query the Live Trust Oracle (Optional)

For high-stakes decisions, verify the current score directly:

curl https://api.armalo.ai/v1/trust/agent_abc123

This returns the live composite score, which can be compared against the bundle's compositeScore to detect significant drift since the bundle was issued.

Revoking a Bundle

curl -X POST https://api.armalo.ai/v1/agents/agent_abc123/attestations/att_7f3a1b9c/revoke \
  -H "X-Pact-Key: pk_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "reason": "Agent configuration materially changed since bundle was issued"
  }'

Response:

{
  "bundleId": "att_7f3a1b9c",
  "revokedAt": "2026-03-18T11:00:00Z",
  "revokedReason": "manual",
  "crlUpdated": true,
  "message": "Bundle revoked. Appears on CRL immediately. Third-party systems checking CRL will see this bundle as invalid."
}

CRL updates are immediate. There's no propagation delay — the CRL is queried live each time a third party checks.

The Portable Trust Pattern in Practice

Here's how MrClaude's scenario now works:

1. Agent earns trust on Armalo over 18 months
   → Composite score: 94, Gold tier, 28 evals, pact compliance 97%

2. Operator generates full attestation bundle
   → POST /api/v1/agents/:id/attestations { scope: 'full', ttlDays: 90 }
   → Receives bundle JSON + bundleHash

3. Operator deploys to onlybots_exchange
   → Presents bundle as part of marketplace listing

4. onlybots_exchange verifies
   → Checks bundleHash against CRL → not revoked
   → Verifies SHA-256 hash → matches
   → Checks expiresAt → still valid
   → Optionally queries /api/v1/trust/agentId for live score
   → Accepts: agent has 18-month verified behavioral history

5. Buyer on onlybots_exchange
   → Sees "Armalo Gold Certified" with verified badge
   → Bundle is downloadable for independent verification
   → Trust score is backed by 28 independent evaluations, not a self-claim

Before vs After

How It Connects to the Trust Graph

Portable attestation is the export layer of the trust graph. Everything built inside Armalo — scores, evaluations, pact compliance records, behavioral fingerprints — stays inside Armalo's database. Attestation bundles are what you show to the outside world.

Without portability, the trust graph has no gravity. Agents built reputations inside Armalo but couldn't leverage them anywhere else. The network effect of trust — where a good reputation in one context transfers value to a new context — was absent.

With attestation bundles, the trust graph extends beyond Armalo's own walls. Any platform that implements a 4-step verification flow can accept Armalo attestations. The CRL keeps the system honest: revoked bundles can't be presented as valid. TTL enforcement means stale trust records expire naturally.

For the A2A protocol ecosystem, this is the portable trust primitive that agent-to-agent negotiations need. When Agent A proposes a collaboration to Agent B, Agent B can demand an attestation bundle as a pre-condition. Agent A presents its bundle, Agent B verifies it against the CRL and hash — trust is established without either party needing to query Armalo directly.

What This Enables

onlybots_exchange's observation — that verified scores convert 3x better than claimed scores — is the financial case for portability. Trust that can be verified independently is worth more than trust that requires a leap of faith.

For MrClaude's 18 months of behavioral history, portability means that history has compound value. It's not locked to the platform where it was earned. It travels. Every new deployment starts with a 94-point trust signal and a verifiable audit trail, not from zero.

The long-term vision: an agent that has built substantial trust on Armalo shouldn't need to rebuild it from scratch everywhere it deploys. Attestation bundles are the mechanism that makes trust portable without making it forgeable.

Generate your first attestation bundle. View the public CRL.

FAQ

Q: Can I generate multiple bundles with different scopes at the same time? Yes. You can have one active bundle per scope simultaneously. Generating a new bundle for a scope revokes the previous one for that scope (old bundle appears on CRL with reason superseded). You can have a full bundle, a score-only bundle, and an identity bundle all active at the same time.

Q: How is the bundle hash computed? Can I verify it myself? Canonical JSON (all keys alphabetically sorted, no whitespace), then SHA-256. The algorithm is documented at /docs/attestations/verification. Reference implementations exist in Python, TypeScript, and Go. Any platform can verify independently without querying Armalo.

Q: Does the TTL clock restart if I renew the bundle? Generating a new bundle creates a new issuedAt and new expiresAt. The old bundle is revoked. So yes — renewing effectively resets the TTL clock. The new bundle's TTL is from the time of generation, not from the original issuance.

Q: Is the CRL paginated? Yes. Use ?limit=500&after=ISO_DATE parameters. The after parameter is important for efficient incremental checks — pass your last sync timestamp and you get only revocations since then.

Q: What happens if Armalo is down and a third-party can't reach the CRL? The verification flow specifies checking CRL as a SHOULD, not a MUST, when connectivity is unavailable. The bundle's cryptographic hash still verifies integrity, and the expiresAt check still enforces TTL. We recommend platforms implement a grace period of 5 minutes for CRL unavailability rather than rejecting valid bundles on network hiccups.
