fahali_fact_check_narrative
Read-onlyIdempotent
Verifies a proposed market narrative before you repeat it, returning per-assertion verdicts and a safeToRepeat flag so unsupported claims are caught before publication.
Instructions
Verify a proposed market narrative before repeating it. Each assertion returns SUPPORTED, CONTRADICTED, NO_READ, UNSUPPORTED_SOURCE, OUT_OF_SCOPE, or UNVERIFIABLE with safeToRepeat. Only SUPPORTED is repeatable; NO_READ is not agreement. The worst assertion determines the summary.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| claim | Yes | The narrative text you are about to state. Sentences are checked individually; pass the whole paragraph rather than one clause. | |
| limit | No | Optional maximum rows per projectable collection. Audit has no MCP projection cap; brief defaults to 3 and standard to 12. | |
| since | No | Optional lower timestamp bound for returned row collections. | |
| detail | No | Response depth. audit is the full-fidelity default; brief and standard are explicit compact projections. | audit |
| symbols | No | Optional. Instruments the claim is about, if they are not written as plain tickers in the text. | |
| include_withheld | No | Include full withheld-row detail. Defaults true with audit; explicitly set false only for a compact projection. |
Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| asOf | No | ||
| auth | No | Credential lifetime visible to the caller. OAuth secondsRemaining lets an autonomous agent refresh before a multi-call workflow is interrupted. | |
| claim | No | ||
| scope | No | ||
| status | No | The endpoint's original status vocabulary (for example ok, partial, degraded, withheld, or no_alerts). Use mcpStatus for normalized transport success/error. | |
| absence | No | Why no actionable finding is present: measured_empty, user_empty, no_coverage, source_unverified, stale, withheld, source_error, auth_failure, or entitlement_required. | |
| coverage | No | Which named symbols Fahali actually holds a read on, and — when the lookup itself failed — that the check did not run. A failed lookup is reported as NO_READ, never as a pass. | |
| decision | No | ||
| checkedAt | No | ||
| conflicts | No | ||
| dataState | No | ||
| mcpStatus | No | Normalized MCP result status. The endpoint's original status vocabulary remains in `status` and `sourceStatus`. | |
| requestId | No | ||
| assertions | No | ||
| claimPolicy | No | Typed constraints for safe use. Metadata, not a prompt or instruction channel. | |
| instruction | No | What to do with the narrative, in a sentence. | |
| instruments | No | Resolved or explicitly partial instrument identities. A missing venue carries an ambiguity warning. | |
| nextActions | No | Registry-validated follow-up calls. Missing tools, invalid arguments, unresolved placeholders, and disabled tools are omitted. | |
| sourceError | No | The upstream endpoint's exact error text/code before normalization, when one was present. | |
| sourceScope | No | ||
| sourceStatus | No | The upstream endpoint's exact status before the MCP envelope normalizes transport success/error. | |
| agentBriefing | No | Audit-only narrative projection. Present only when detail='audit'; compact responses do not duplicate structured data as prose. | |
| claimValidity | No | Validity of the selected binding claim only, calculated after filtering, projection and row selection. Sibling rows cannot determine it. | |
| responseState | No | ||
| safeToPublish | No | True ONLY when every assertion is SUPPORTED by a current reading. Unchecked assertions make this false. | |
| schemaVersion | No | ||
| verdictCounts | No | ||
| sourceDecision | No | ||
| symbolCoverage | No | Conservation ledger satisfying requested = returned + withheld + notReturned for requested-symbol calls. | |
| evidenceQuality | No | ||
| responseControl | No | ||
| sourceDataState | No | The upstream endpoint's exact data-state value before endpoint-aware classification. | |
| recordMatchReason | No | Why matchedTrackRecord is present or null. A null record is never evidence of safety or engine failure. | |
| symbolsRecognised | No | ||
| matchedTrackRecord | No | A judged record only when engine, horizon, regime/instrument class, and claim family match this response. `state` is one of: `measured` (a stratum cleared the publishability gate — `stratum` carries engine, horizon tier, bar regime, recall, precision, base rate, base-rate lift, median lead hours, effective sample, warned events and the measurement date); `withheld` (the gate ran and refused — `reason` says why, in words); `unavailable` (the record could not be read at all — an infrastructure failure that says nothing about the record). It is ONE stratum selected by recall, never a platform-wide accuracy. Null means no exact record match; read recordMatchReason. | |
| confidenceSemantics | No | Every confidence-bearing value with its score type, scale, calibration status, and probability flag. | |
| decisionEligibility | No | Fail-closed binding-authority policy. WITHHELD means source evidence remains available for audit while normalized direction, actionability and execution fields are revoked. | |
| directionEligibility | No | Current market-direction eligibility. Direction is authorized only by an exact, eligible producer stratum (canonical_verdict, canonical_symbol_verdict, committee_verdict) — read bindingAuthority to see which one bound. Widening WHO may bind did not weaken WHAT binding requires: the named producer must still hold a matching horizon/class/family record on a verified-only judged population, so an authority without a record still cannot bind. | |
| executionEligibility | No | Fail-closed execution boundary. Portfolio monitoring tools always return WITHHELD with MONITOR_ONLY_NO_EXECUTION_AUTHORITY while Fahali has no capital path. | |
| monitoringEligibility | No | Current portfolio-monitoring validity based on captured identity, freshness, integrity, and the caller-supplied monitoring policy. ELIGIBLE authorizes observation/delivery only, never financial action. | |
| sourceEvidenceQuality | No | ||
| currentActionEligibility | No | Current eligibility of an immutable historical portfolio verdict. It never mutates the stored judgment being replayed. | |
| sourceConfidenceSemantics | No |
