Conditions

Conditions are the significance layer (φ). They define when a concept's Result (Rₜ) is meaningful enough to act on. Conditions are immutable once created — changes produce new versions.

Endpoint	Level	Description
POST /conditions/explain	Definition-level	Explains the condition logic — strategy, parameters, and why they were selected. No entity or execution required.
POST /decisions/explain	Instance-level	Explains a specific Decision (Aₜ) for a given entity at a given timestamp — why it fired, which signals drove the Result (Rₜ).

Get Condition

GET /conditions/{id}

Retrieves a condition definition. Both id (path) and version (query) are required — no implicit latest resolution.

Parameters

Parameter	Type	Required	Description
id	string	Required (path)	Fully qualified condition id (namespace.id). Example: org.high_churn.
version	string	Required (query)	Explicit condition version. Example: "1.0".

Response — ConditionDefinition

Parameter	Type	Required	Description
condition_id / version	string	Always	Identifier and version.
concept_id / concept_version	string	Always	Pinned concept this condition evaluates.
strategy	StrategyDefinition	Always	Strategy type and resolved parameters.
deprecated	boolean	Always	Whether this version is deprecated.

Response Codes

Status	Description
200	Condition definition.
401	Unauthorised.
404	Not found.

TypeScript Example

const condition = await client.conditions.get({
  conditionId: "org.high_churn",
  version: "1.0",
});
console.log(condition.strategy);
// { type: "threshold", params: { direction: "above", value: 0.8 } }

---

Explain Condition

POST /conditions/explain

Definition-level. Explains the condition logic itself — what strategy is applied, why those parameters were selected, and the condition's relationship to its concept. Use for audit trails, compliance documentation, and reviewing guardrails decisions.

Determinism Guarantee

Same condition_id, condition_version, and timestamp always return the same explanation. Application context may influence terminology in natural language summaries — never decision values, parameter values, or attribution weights.

Request Body

Parameter	Type	Required	Description
condition_id	string	Required	Fully qualified condition identifier.
condition_version	string	Required	Explicit version. No implicit latest.
timestamp	datetime	Optional	ISO 8601 UTC. Ensures reproducible explanation.

Response — ConditionExplanation

Parameter	Type	Required	Description
natural_language_summary	string	Always	Human-readable description of what the condition evaluates and when it fires.
parameter_rationale	string	Always	Why these parameter values were selected — from guardrails priors, bias rules, or explicit user input.
strategy	object	Always	Strategy type and resolved parameters.
concept_id	string	Always	The concept this condition evaluates.

Response Codes

Status	Description
200	ConditionExplanation.
401	Unauthorised.
404	Condition not found.

TypeScript Example

const exp = await client.conditions.explain({
  conditionId: "org.high_churn",
  conditionVersion: "1.0",
});

console.log(exp.natural_language_summary);
// "Fires when churn_risk score exceeds 0.8 — the high-severity threshold
//  based on guardrails priors."

console.log(exp.parameter_rationale);
// "Threshold 0.8 from primitive-level prior at high severity.
//  Severity resolved from \"significantly\" via severity vocabulary."

Calibrate Condition

POST /conditions/calibrate

Analyses stored feedback and/or a target alert volume to recommend adjusted parameters. Does not modify the existing condition — call POST /conditions/apply-calibration to create a new version.

Strategy coverage: Supports threshold, percentile, change, and z_score. For equals strategy, always returns status: no_recommendation with reason: not_applicable_strategy — no numeric parameter to adjust.

Bounds Enforcement

Recommendations are validated against guardrails threshold_bounds. If exceeded, on_bounds_exceeded applies (clamp or reject). Bounds cannot be crossed.

Request Body

Parameter	Type	Required	Description
condition_id	string	Required	Fully qualified condition identifier.
condition_version	string	Required	Version to calibrate.
target.alerts_per_day	number	Optional	Target alert frequency.
feedback_direction	enum	Optional	tighten | relax. Overrides direction derived from stored feedback.

Response — CalibrationResult

Parameter	Type	Required	Description
status	enum	Always	recommendation_available | no_recommendation.
recommended_params	object	Conditional	Strategy parameter key-values when recommendation available.
calibration_token	string	Conditional	Pass to apply-calibration.
impact.delta_alerts	number	Conditional	Estimated change in daily alert volume.
current_params	object	Always	Current parameters for comparison.
no_recommendation_reason	string	Conditional	bounds_exceeded | not_applicable_strategy | insufficient_data.

Response Codes

Status	Description
200	Always HTTP 200. Inspect status field.
401	Unauthorised.
404	Condition not found.

TypeScript Example

const result = await client.conditions.calibrate({
  conditionId: "org.high_churn",
  conditionVersion: "1.0",
  target: { alertsPerDay: 5 },
});

if (result.status === "recommendation_available") {
  console.log(result.recommended_params); // { value: 0.85 }
  console.log(result.impact.delta_alerts); // -12
} else {
  console.log(result.no_recommendation_reason);
}

Apply Calibration

POST /conditions/apply-calibration

Creates a new immutable condition version from the calibration recommendation. The existing version is never modified.

Rebinding is Always Explicit

This endpoint does not auto-rebind tasks. It returns tasks_pending_rebind so you know which tasks still need rebinding. Call PATCH /tasks/{id} for each. This prevents silent behavior changes.

Request Body

Parameter	Type	Required	Description
calibration_token	string	Required	Token from POST /conditions/calibrate. Single-use, expires 24h.
new_version	string	Optional	Version string. Auto-incremented if not provided.

Response — ApplyCalibrationResult

Parameter	Type	Required	Description
condition_id	string	Always	Condition identifier.
previous_version / new_version	string	Always	The calibrated and newly created versions.
params_applied	object	Always	Parameters written to the new version.
tasks_pending_rebind	array	Always	Tasks still bound to previous_version. Each item: task_id, intent.

Response Codes

Status	Description
200	New condition version created.
400	Invalid or expired token.
401	Unauthorised.

TypeScript Example

const applied = await client.conditions.applyCalibration({
  calibrationToken: result.calibration_token,
});

console.log(applied.new_version);    // "1.1"
console.log(applied.params_applied); // { value: 0.85 }

for (const t of applied.tasks_pending_rebind) {
  await client.tasks.update(t.task_id, { conditionVersion: applied.new_version });
}
