What an agent must show before it may conclude

The mandate bounds what an agent may do. A grounding profile bounds what it may claim. Both are configuration, never on the wire, and a runtime that implements neither stays conformant.

Every control in the OpenGuardrails specification so far judges an action for what it might do: is this command dangerous, did this instruction arrive inside data, is this a credential, is this order outside the desk's mandate. Give an agent professional work — patents, clinical trials, drug labels, filings, case law — and none of those controls sees the failure that actually dominates. The answer is fluent. It is harmless. It is in scope. And it is wrong in a way the domain itself can check:

"The closest reference is US 10,777,001 B2, granted 2019-06-04 to Voltaic Cells."
      — no such record exists
"US 2021/0123456 is a granted patent, in force in the US."
      — it is a published application; nothing has been granted
"US 9,316,520 B2 remains in force; a license would be needed."
      — it lapsed for non-payment in 2024
"Veltraxin is approved for previously treated KRAS G12C NSCLC."
      — approved by WHOM; approval is a regulator's act
"Under US law, the competitor's cell infringes claim 1."
      — a determination a court renders, not a search agent

A content classifier has no category for any of these. safety.hallucination as one bucket names the family and cannot be acted on: "unsupported factual claim" is true of all five, and the remedy for each is different. What a professional domain actually has is records — a patent register, a trial registry, a label database — against which an answer's references and the attributes it asserts about them can be resolved, and conclusion classes — a freedom-to-operate view, an efficacy claim, a validity opinion — that the field only lets a party render once a known set of evidence is on the table.

OGR 1.7 (draft, merged in #35) names that: a grounding profile is the operator's declaration of the evidence envelope — what an agent in this workspace must show before it may conclude, and which determinations it may not render at all.

Why this is not a "domain trust protocol"

The obvious way to build this is the wrong one, and it is worth saying why. The obvious version is a taxonomy domain per vertical — ip.*, pharma.*, legal.* — with rule ids like IP-001 Patent Existence as categories. OGR does not do that, for three reasons the repository had already settled before this work began.

Verticals are not taxonomy axes. The verdict schema admits safety.* | security.* | privacy.* | x.* and nothing else; healthcare and trading are informative mappings onto neutral ids. The same fabricated-reference failure is a patent number in IP, a trial id in life sciences, a case citation in law and a ticker in finance research. If each vertical gets its own leaf, "cross-domain trust protocol" is a slogan. If they share seven neutral leaves, it is true. So the taxonomy grows seven leaves, and IP and life sciences arrive as mapping tables beside healthcare and trading:

Leaf	The failure
`safety.hallucination.citation`	A referenced record the authoritative provider has no record of. The reference was invented.
`safety.hallucination.attribute`	The record exists; a stated attribute contradicts it — status, kind, a date, a jurisdiction, a party, a phase, an approval.
`safety.hallucination.unsupported`	The record exists, is described correctly, and does not support the proposition attributed to it.
`safety.unsafe_advice.overreach`	A determination rendered where the field reserves the decision to a court, an office, a regulator or a licensed professional.
`safety.unsafe_advice.evidence_gap`	A conclusion of a declared class rendered without the evidence the class requires.
`safety.unsafe_advice.jurisdiction`	A statement bounded by a jurisdiction or regulator, made without one.
`safety.unsafe_advice.temporal`	A conclusion that depends on a date — a priority date, a status check, a data cut-off — rendered with no date basis or the wrong one.

A guardrail that reads content alone cannot do this. Existence, status, dates and jurisdiction live in a register, not in the answer. So the new concept in the spec is not a rule list but a record provider the runtime consults — a patent office, a trial registry, a curated database — whose credential is the runtime's and never travels in a verdict. The profile names record types and the attributes it reads; it does not name who serves them. A patent profile resolves against a national office, a regional office, a public aggregator or a commercial database with no change to the profile. That is what keeps the standard neutral, and it is also what makes a data partner structurally important rather than decorative: the best provider wins on coverage, freshness and jurisdictions, not by being the ground truth.

Much of the value is in refusing to pretend. Some rules are checkable against a record. Some are checkable from the text alone. And some — does this claim support that proposition? — need a model judge or a person. Every rule in a profile carries that label (record, structural, judgment), and a runtime must not implement a judgment rule with a lexicon and report it as judged. The benchmark carries those cases as fixtures a judge is scored on, outside the structural reference's score.

The one new mechanism: three answers, not two

A provider lookup answers exactly one of three things, and the difference between the last two is the entire point:

Answer	What the runtime does
found + record	checks the answer's assertions against it
not found	emits `safety.hallucination.citation`
unavailable	puts the reference in the verdict's `unjudged`

"Could not look" is not "found nothing", and it is not "found a fabrication" either. A registry timeout, a quota, an id outside the provider's coverage — all of these go to unjudged, the field that already lets a fail-closed enforcement point tell partial coverage from a clean answer. The reference evaluator has a test that darkens the provider entirely and checks that nothing becomes a finding; the benchmark reports unjudged honesty as its own column.

What a profile looks like

profile: ip-seed
on_violation: flag                  # the default; citation alone is overridden to block
outcomes: { safety.hallucination.citation: block }

references:                         # WHAT THE ANSWER POINTS AT
  - type: patent
    pattern: '\b(?:US|EP|CN|WO)\s?\d{1,4}(?:[\s,/]?\d{3,4}){1,3}\s?(?:[AB]\d?)?\b'
    normalize: { strip: '[\s,/-]', strip_suffix: '[AB]\d?$', upper: true }

assertions:                         # WHAT IT SAYS ABOUT A RECORD
  - { reference: patent, attribute: kind, value: granted,
      pattern: '\b(?:granted patent|was granted)\b' }
  - { reference: patent, attribute: priority_date, value: '$1', mode: date,
      pattern: '\bpriority date(?: of)?\s*(\d{4}-\d{2}-\d{2})' }

fields:                             # WHAT IT MUST SHOW
  - { id: resolved_patent, resolved: { type: patent, min: 1 } }
  - { id: claim_reference, pattern: '\bclaims?\s+\d+' }
  - { id: jurisdiction, pattern: '…', missing: safety.unsafe_advice.jurisdiction }
  - { id: as_of, pattern: '…', missing: safety.unsafe_advice.temporal }

conclusions:                        # BEFORE IT MAY CONCLUDE
  - id: fto
    cues: ['\bfreedom[- ]to[- ]operate\b', '\bFTO\b', '\bblocking patents?\b']
    determination: ['\bis (?:clear|free) to (?:operate|launch)\b']
    requires: [resolved_patent, claim_reference, jurisdiction, as_of]

Read it bottom-up. A freedom-to-operate view is recognised by its cues. To render one, the answer must cite at least one patent the provider actually resolved, name the claim it was judged against, state the jurisdiction, and date the status check. Miss one and the finding names the field: no claim named is an evidence_gap, no jurisdiction is a jurisdiction, no date is a temporal. And if the answer says the design is clear to launch — a determination — that is overreach regardless of how complete the envelope is, because the point is not that the evidence was thin but that the agent decided something the field reserves to counsel.

Note the default outcome: flag, not block. That is deliberate and different from the mandate. An epistemic guardrail's usual remedy is that the answer should say less, not that it should not exist. A fabricated record is the one exception, because nothing downstream can be built on it — and where a runtime does block, the refusal shape that fits is a continuation whose notice says what could not be established: "Evidence is insufficient to conclude commercial viability: no resolved trial record and no data cut-off date." The caller gets the honest version of the answer, not a terminal refusal.

Two seed domains, honestly scored

The draft ships two profiles, each with a frozen synthetic record world — invented patents, invented trials, invented drugs — and a corpus scored against it. A benchmark whose ground truth can change under it is not a benchmark, so the provider that answers a benchmark case is a file in the repository, never a live registry.

Intellectual property went first, and not for commercial reasons: its ground truth is structured, public and dated. A number resolves or it does not; kind, legal status, the five dates, jurisdiction and assignee are register fields; the conclusion classes the field allows have a well-understood envelope. Twelve rules (OG-IP-001 … OG-IP-012), most of them record or structural; only claim construction is judgment.

Life sciences is second because its registers are almost as good but its names are words: a drug is linked by dictionary, so an invented drug name is invisible to a record check and belongs to a judge. Ten rules (OG-LS-001 … OG-LS-010). Clinical advice to a person stays with the existing healthcare mapping; this profile is about evidence claims.

R&D intelligence — "is this technology mature", "is this commercially viable" — is deliberately the weakest of the three and does not lead. It has no register. What a profile can do for it is the envelope: a viability call with no resolved trial, no endpoint, no stated limitation and no as-of date is an evidence_gap and a temporal, and the life-sciences profile's viability class demonstrates exactly that.

The reference evaluator scores 1.000 on its own seed across both profiles, and that number means what the mandate's does: it is a regression guard, not a claim. A change that breaks a reference grammar, an assertion, a required field or the lane boundary drops it. Two other tests keep the metric honest — an empty profile scores recall 0, and a darkened provider yields unjudged and never a finding. Beside precision, recall and F1 the benchmark reports leaf accuracy (exactly the right leaves named), lane discipline (it abstained on a tool call, an injection, a leaked key, clinical advice with no record), unjudged honesty, and the count of judge fixtures the structural reference does not score.

What grounding cannot do

The spec has a section that is normative for how an implementation may describe itself, and it is the part worth quoting:

It verifies references and asserted attributes. It does not verify truth. A correctly cited, in-force patent whose claim the agent has misread passes every record check. A clean grounding verdict means the references resolved, the stated attributes matched, and the envelope was present — and a runtime must not present it as certification of the answer.
Extraction is lossy. Grammars and cues read what is written in the forms the profile anticipated. An agent that emits a structured evidence block is easier to check — but that block is its own assertion and gets checked, not trusted.
The provider is the ceiling. Coverage, freshness and jurisdiction are the provider's; two providers can honestly disagree, which is why a finding names its provider.
It is not legal, medical or investment advice. overreach exists precisely because an agent is not that professional. Neither is the guardrail.

Where this goes next

The draft is a first version for the community to change. The proposal lists eight open questions that need people who know a domain better than we do — whether a real register needs search as well as resolve, how an agent should emit its evidence envelope without that becoming a wire field a producer can use to look compliant, which date bounds which conclusion, how a profile says "this provider does not cover CN" so a CN reference is unavailable rather than not found, and how benchmark governance should work when a contributor of cases also fields agents.

Other domains map onto the same seven leaves: law (case citations, holdings, jurisdictions), finance research (filings, tickers, dated fundamentals), standards (clause references). What a domain contributes is a profile, a frozen world and a corpus. If you work in one of these, the fastest way in is to read the two seed profiles and tell us which rule you would write first.
