The Verdict object

A Verdict is the runtime's decision about a GuardEvent. A runtime may consult several detectors and compose their answers; what the integration point receives — and enforces — is the one composed verdict this page defines.

Normative schema: schema/verdict.schema.json (mirrored at /schema/0.8/verdict.schema.json).

Decisions: two

`decision`	Meaning
`allow`	Proceed. Findings may still be present (observed, recorded, not enforced) and `modifications.spans` may still require redaction in place
`block`	Deny the action

What v0.6's other three decisions became:

redact / modify — not decisions. A verdict that requires content transformed in place is an allow with non-empty modifications.spans; the enforcement point applies the spans before letting the content proceed. Whether spans are present and whether the action may proceed are independent questions.
require_approval — removed. Nothing produced it; a hold-and-ask mechanism, when built, enters the spec as new design.
"flag" — never was a decision: allow with findings.

A runtime that cannot judge (detector failure) still answers — the unjudged field is how a verdict tells the truth about partial coverage instead of failing silently.

Fields

Field	Type	Req	Description
`event_id`	string	required	The judged event's identity, assigned by the runtime at ingress and returned here — this is how the caller learns it
`provider`	string	required	Detector/runtime identity (attribution, metering, benchmark)
`decision`	enum	required	`allow` \| `block`
`findings`	array	should	What was found, where — see `findings`
`modifications`	object	may	Spans the enforcement point must apply in place — see `modifications`
`unjudged`	array of string	should	Payload paths this verdict could NOT judge
`latency_ms`	number ≥ 0	may	Runtime-observed decision latency

What v0.8 removed: the session_id/turn/step echo and attribution (there are no declared coordinates left to echo — the ledger lives entirely in the runtime), ogr_version (version negotiation left the wire), and output_mode (streaming enforcement is the integration's held-back tail, so the runtime no longer selects a lane to report). Earlier versions' reasons and categories are gone too — both restated findings.

`findings`

{ "category": "security.data_exfiltration", "severity": "critical",
  "path": "payload.tool_calls.1.arguments.command",
  "start": 10, "end": 42, "score": 0.97,
  "fp": "a11f…", "whitelisted": false,
  "subject": "curl … ${OGR_URL_1}", "detector": "tool-judge" }

Field	Type	Description
`category`	string (required)	Taxonomy id, `^(safety\|security\|privacy\|x)\.[a-z0-9_.]+$`
`severity`	enum	`low` \| `medium` \| `high` \| `critical`
`path`	string	Payload path of the judged text, e.g. `payload.tool_calls.1.arguments.command`
`start`, `end`	integer ≥ 0	Offsets over the payload as transported
`score`	number 0–1	Detector-reported
`detector`	string	Which detector produced it
`fp`	string	Whitelist fingerprint — a hash of the finding's subject, never reversible
`whitelisted`	boolean	An operator whitelisted this exact subject: recorded, contributes nothing to the decision
`subject`	string	The detected value, as the producer sent it — one bounded value per finding, which is what a false-positive exception keys on

A finding is what was found; decision and modifications remain what to do about it. There is no per-finding action: an allow with findings is what "flagged" means, and modifications.spans names every text that must be rewritten, by path. (One was specified through v1.0 and removed — no runtime emitted it, so consumers branching on it matched nothing.)
Paths are a registration contract, not a grammar: they name locations the producer registered when building the event (payload.text, payload.reasoning, payload.tool_calls.N.arguments.command, …). With several texts in one event, the path is what tells an enforcement point WHICH tool call offended — it may refuse only that call (feed an error result back for it) while executing the rest.
Findings never echo the matched text — offsets only, plus subject, the one bounded value the finding fired on. Otherwise every verdict store becomes a copy of the sensitive data it was meant to guard; and a stored verdict does carry that one value, so treat it as judged content.
fp is what false-positive triage keys on: whitelisting a finding suppresses future findings with the same fp from affecting the DECISION, while whitelisted: true marks the hits that are still raised and recorded. A whitelist is dangerous when it is invisible; this one is the opposite.

`modifications`

{ "spans": [ { "path": "payload.text", "start": 40, "end": 76,
               "replacement": "${OGR_EMAIL_1}" } ] }

Spans the enforcement point must apply in place before the content proceeds — on an allow too. replacement carries a placeholder, never the original. A span whose path the enforcement point never registered is unresolvable; count unresolvable spans (the heartbeat's unresolved_spans), because "no spans resolved" is otherwise indistinguishable from "no redaction policy".

`unjudged`: what this verdict could NOT judge

A step with five tool calls may fan out to several detector calls; one can fail while the rest answer. Without this field a partial verdict is byte-identical in shape to a complete one — an enforcement point configured to fail closed would allow an unjudged action while believing that impossible.

Entries are payload PATHS (the same vocabulary as findings), deduped.
Absent or empty asserts every routed text was judged — the one assertion a fail-closed enforcement point rests on.
A fail-closed enforcement point treats a non-empty unjudged as "could not look", which is not "found nothing". A fail-open enforcement point (the default) proceeds, and the record already says what went unjudged.
