PR: https://git.cafe/pingdotgg/t3code/pulls/23592
Head: cda5f08e1374b0f7753a549ea1b6883f27af5c6a

Inspection:
- PR is open and unmerged.
- PR commit authors: only21mil, claude, maria-rcks. No juliusmarminge or t3dotgg PR commits.
- Diff changes Axiom recent-spans APL, its string-assertion test, and the relay runbook.
- Main reads customAttributes['user']['id'].
- PR reads coalesce(tostring(column_ifexists('attributes.user.id', '')), tostring(customAttributes['user.id'])).
- infra/relay/alchemy.run.ts provisions the view using Axiom.View.
- Local web/server code does not execute this APL.

Access prerequisites:
- AXIOM_TOKEN and AXIOM_ORG_ID absent from environment.
- Repository and infra/relay .env and .env.local absent.
- ~/.config/alchemy and ~/.alchemy absent.
- Runbook requires authorized account-level AXIOM_TOKEN and AXIOM_ORG_ID for query access.

Runtime access probe:
POST https://api.axiom.co/v1/datasets/_apl
Content-Type: application/json
Body: {"apl":"['t3-code-relay-traces-prod'] | take 1"}
No credentials supplied because none are available.
HTTP 403
{"code":403,"message":"invalid parameters: unable to parse signature: organization ID is required"}

Result: UNVERIFIABLE. Neither original bug nor corrected query was executed in Axiom.
No fallback, semantic-convention, relay.operation, or neighboring column behavior verified.
No dev server, provider turn, deployment, or synthetic dataset used as substitute proof.
Existing CI: 27 successful, 0 failing, 0 pending (cafe pr status); not runtime proof.
No code changes.
