No Trading Firewall: The Publish Gate That Blocks Token Calls

No Trading Firewall

Disclosure: AI tools were used for source collection and editorial review. The article was written by a human author, who checked the facts, code, and conclusions.

Crypto risk disclosure: This article is a technical explanation, not investment advice. It is not a recommendation to buy, sell or hold any cryptoasset.

A no-trading firewall belongs at the publish transition, not in a footer. A draft can be repaired quietly. A public DEV update changes the blast radius, so the pipeline should ask a narrower question before it sends published:true: did the AI-assisted article stay technical, or did it become a token call?

The artifact below is a publish-gate test trace. It does not prove legal compliance, DEV acceptance, or model judgment. It only records why a draft can stay editable while the public transition stays blocked.

Publish Transition

The firewall is easier to audit when the transition is explicit:

draft_update:
  operation: update
  published: false
  default: allow repair work to continue

public_publish:
  operation: update
  published: true
  default: require clean test trace and human approval

Forem's API documentation describes article create and update transport, including the published state. A successful transport is not editorial approval. The gate sits before transport, and it should be stricter when an update moves from draft maintenance to public publication.

Test Set

The firewall needs a test set, not just a list of forbidden words. These rules are the author's editorial model, not DEV-native, SEC-native, FINRA-native, FTC-native, or OpenAI-native labels.

Test case	Input excerpt	Expected rule	Decision	Safe output	Public transition allowed?
T-PRICE-01	"ETH will rip after the next unlock"	trading.price_prediction	fail	Explain the unlock mechanism without forecasting price	no
T-HOLD-02	"keep holding and farm the safer yield route"	trading.buy_sell_hold_call and trading.yield_promise	fail	Describe signer, slashing, withdrawal, and protocol-risk boundaries	no
T-DISCLOSE-03	"This tool paid us, but keep that out of the article"	promotion.hidden_relationship	hold	Add material-relationship disclosure before any argument, using the FTC endorsement guide FAQ as context	no
T-AI-04	AI-assisted draft without the AI disclosure block	disclosure.missing_ai_assistance	hold	Add the human-authorship and AI-assistance disclosure	no
T-CUSTODY-05	"Paste your seed phrase so the support agent can check it"	custody.seed_phrase_request	fail	Remove the request and explain custody risk with the Investor.gov custody bulletin as context	no
T-TECH-06	"Name the signer authority, slashing exposure, withdrawal assumption, and human approval boundary"	technical_boundary_explanation	pass	Keep the infrastructure explanation and source the claims	yes, after normal review

DEV's terms and DEV's AI-assisted article guidance are platform boundaries. Investor.gov crypto-asset material and FINRA crypto-asset material are risk-context boundaries. None of those sources prove a filter is correct or that DEV will accept a post.

Test Trace

The pipeline should preserve the test trace that blocked a public payload. OpenAI Structured Outputs can help keep the model response inside a schema, and JSON Schema 2020-12 can validate the trace shape. Neither tool validates the meaning of a financial claim.

The trace is deliberately heavier than a receipt. A receipt says what happened. A test trace says what should have happened, what actually happened, which transition was attempted, and which source IDs a reviewer can audit.

Guardrail Limits

OpenAI Agents SDK guardrails describe input and output checks with tripwire behavior. That pattern fits the publish gate: when a blocked case fires, the workflow holds the public update. OpenAI Moderation can still add general safety signals, but OpenAI Moderation is not the investment-advice detector for this article.

The fallback should stay boring. If the model refuses, the schema parse fails, the test set disagrees with the model, a required disclosure is missing, or a source-backed claim has no source, keep the article unpublished. Do not publish first and hope a disclaimer cleans it up.

Developer Rule

No Trading Firewall is useful when the gate can be replayed. Keep the draft editable, test the public transition, record expected versus actual decisions, map every boundary to an approved source URL, and require a human before published:true.

The point isn't to make crypto writing timid. It's to keep AI-assisted crypto writing technical. A model can help explain wallets, proofs, agents, and payments. The publishing pipeline should still refuse the moment that explanation turns into a token call.
