Picks a channel, tests it right.
Shadow plans and policies grow,
Safe fallbacks keep streams aglow.
The requested name stays bright—
While billing follows work done right.

Guard coldStartQualityPrior against an out-of-range tier.

The function indexes a fixed four-element array with policy.Tier. A tier below 0 or above 3 panics inside the relay request path. routingsetting.Normalize bounds Tier to 0..3, but Catalog accepts any routingsetting.Config, including a config that never passed through Normalize. NewCatalog has no such precondition in its signature.

Clamp the index.

97-114: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Bound the request body before decoding the policy document.

common.DecodeJson(c.Request.Body, &request) reads the whole body into memory. ValidatePolicyDocument checks len(raw) > routingsetting.MaxPolicyDocumentBytes only after the decode completes, so the size limit does not protect the decode step. The design document docs/superpowers/specs/2026-08-20-multi-instance-admin-intelligent-routing-design.md line 324 requires explicit size limits on all request bodies.

The endpoint requires root authorization, so this is a hardening gap rather than an open attack surface. Wrap the body with http.MaxBytesReader before decoding in CreateIntelligentRoutingPolicy and UpdateIntelligentRoutingPolicy.

Return explicit DTOs instead of database models.

ListIntelligentRoutingPolicies, GetIntelligentRoutingPolicy, and GetIntelligentRoutingRollout marshal model.IntelligentRoutingPolicy and model.IntelligentRoutingRollout straight into the response. The design document docs/superpowers/specs/2026-08-20-multi-instance-admin-intelligent-routing-design.md line 297 requires explicit DTOs. dto/intelligent_routing.go already defines request DTOs but no response DTOs.

The practical risk is drift: any later column added to the model becomes part of the administrator API contract without review. Add response DTOs in dto/intelligent_routing.go and map the fields explicitly.

Confirm the final-attempt fallback is intended to ignore both budgets.

When withinTime or withinCost is false, lines 39-43 return finalIndex without any cost or time check. The design document docs/superpowers/specs/2026-08-17-cost-optimized-intelligent-routing-design.md line 193 describes exactly one final attempt after a budget is reached, so the behavior matches the design. The guard is finalUsed, and both the in-budget branch (lines 34-36) and the fallback branch set it, so at most one final attempt runs.

One gap remains: SelectAttempt trusts that the nodes slice matches the slice passed to NewExecutionBudget, because maxCost derives only from nodes[0]. Store the node costs, or store maxCost alongside a plan identifier, so a mismatched slice cannot silently disable the cost budget.

Review the tie behavior of the strongest-candidate search.

strongest starts at the last index and only moves on a strictly greater PredictedSuccess. qualified is sorted by ascending expected cost. When every candidate has the same PredictedSuccess, strongest stays at the last index, which is the most expensive candidate. The planner then reserves the final attempt slot for it, and it can displace a cheaper candidate with identical predicted success.

If the intent is to reserve the highest predicted success at the lowest cost, break ties toward the lower index.

Extract the node-building loop and use a typed dedup key.

The two branches repeat the same loop: dedup by model and channel, enforce MaxEndpointsPerModel, and cap at MaxAttempts. The only differences are the attempt cap and the reserved strongest candidate.

map[[2]interface{}]struct{} also boxes both fields on every insert and lookup. A typed struct key removes the allocation and the type ambiguity.

Accumulate the validation issues instead of returning the first one.

ValidatePolicyDocument returns []ValidationIssue, but every path returns exactly one element. An administrator who submits a policy with several errors must fix them one at a time.

The Normalize failure at Line 54 is the weakest case. It collapses tier errors, price errors, context-limit errors, duplicate models, the model-count limit, and budget errors into one generic policy.invalid code with no field. The caller cannot show the administrator which model or which field is wrong.

Collect the field-level issues in a slice, and continue checking after each failure. For the Normalize step, replicate the field-level checks before you call it so each failure carries its own code and field.

Reserve quota when any route node is billable.

If the first node is free and a fallback node is billable, firstPrice.FreeModel stays true. Lines 202-208 then skip PreConsumeBilling, even though Line 461 sets a positive maximum quota. A failed free node can therefore route to a paid fallback without a pre-consume.

Track whether all planned nodes are free. Set the returned FreeModel value to false when any node requires billing. Add a test with a free first node and a paid fallback.

## Rollback

Set `intelligent_routing_setting.enabled=false`. The existing channel selector resumes immediately without a restart or frontend change. Historical routing audit retains its policy version.

Serialize and constrain policy version allocation.

Publish and rollback compute the next version from a FOR UPDATE query that locks only the latest row, and the empty-table case locks nothing. Concurrent administrators can therefore commit the same version. Because Version has no unique constraint, duplicate versions persist and version lookup becomes ambiguous, allowing a refresh to activate an unintended policy.

Add a database uniqueness constraint for published versions while allowing multiple drafts, and handle unique-constraint conflicts with retry or an explicit revision conflict in both publish and rollback paths.

Use an explicit integer revision for draft updates.

Draft optimistic concurrency currently exposes UpdatedAt as the revision. PostgreSQL stores timestamptz with lower precision than the in-memory time.Time, so a revision returned after creation can differ from the persisted value and cause a subsequent valid update to fail with a revision conflict.

Add a portable monotonic revision column and compare/increment it atomically for draft updates.

Do not swallow the normalization error.

Line 632 already wrote the raw value into the registered intelligent_routing_setting config before this branch runs. If UpdateAndSync then rejects the value, three effects follow:

  1. handleConfigUpdate returns true and updateOptionMap returns nil, so the administrator API reports success. The invalid value also stays in the Option table.
  2. The registered config keeps the invalid value. UpdateAndSync reads registeredConfig, so every later update of any key in this settings group fails normalization again. The setting becomes unupdatable until the process restarts or an administrator writes a value that normalizes.
  3. Only the log records the failure.

Return the error to the caller so UpdateOption rejects the value, and reset the registered config to the last published snapshot.

🐛 Proposed direction
 	} else if configName == "intelligent_routing_setting" {
 		if err := intelligent_routing_setting.UpdateAndSync(); err != nil {
 			common.SysError("failed to normalize intelligent routing setting: " + err.Error())
+			// Restore the last published snapshot so later updates are not blocked
+			// by the rejected value.
+			_ = config.UpdateConfigFromMap(cfg, map[string]string{configKey: previousValue})
 		}
 	}

handleConfigUpdate returns only a bool, so error propagation needs a signature change. Prefer validating the value in validateOptionValue at Line 209 instead. That check runs before the database write and before the in-memory mutation, so it rejects the value with no rollback.

Preserve unknown stream-event fields during model normalization.

When routing changes the model, common.Marshal(streamResponse) drops fields absent from the DTOs, such as sequence_number, trace_id, service_tier, and prompt_cache_key. Use map[string]json.RawMessage for the event and nested response, replace only response.model, and marshal with the common JSON wrappers.

Enforce the complete supported JSON Schema contract.

validateJSONSchemaValue accepts values that violate schema constraints it does not inspect. For example, it accepts an undeclared property when additionalProperties is false, and it accepts a value outside an enum.

Use a complete validator for the supported schema dialect, or reject schemas that contain unsupported constraints. Add regression cases for additionalProperties and enum.

Validate every Responses API function call.

When allowedTools is empty, the len(allowedTools) > 0 condition accepts an undeclared function call. The early return nil also skips validation of later function calls in the same response.

Reject every undeclared function call, including when the request declares no tools. Validate all function-call outputs before accepting the response. Add regression cases for an unsolicited call and for a valid first call followed by an invalid second call.

Synchronize the registered configuration through a shared update boundary.

config.UpdateConfigFromMap mutates the registered &registeredConfig pointer without this package’s lock. UpdateAndSync can read it at the same time. A mutex around Update and UpdateAndSync does not protect that external mutation because it uses only ConfigManager.mutex. Use one lock for both paths, or stop exposing registeredConfig and apply option updates through a package-owned copy-on-write API.

A snapshot refresh failure reports the rollout mutation as failed.

UpdateRollout commits the rollout through control.repository.UpdateRollout, then calls RefreshSnapshot. If the refresh fails, the method returns the error. UpdateIntelligentRoutingRollout in controller/intelligent_routing.go (lines 232-235) maps that error to HTTP 503 and skips recordManageAudit.

The durable mutation already succeeded. The administrator sees a failure, retries with the same revision, and receives a revision conflict. The audit record is also missing for a change that took effect.

Treat the refresh as best-effort. Log the refresh error, record the audit, and return success. Periodic refresh in StartPolicyRefresh repairs the stale snapshot.

♻️ Proposed change
 	updated, err := control.repository.UpdateRollout(revision, rollout)
 	if err != nil {
 		return model.IntelligentRoutingRollout{}, nil, err
 	}
-	if err := control.RefreshSnapshot(ctx); err != nil {
-		return updated, nil, err
-	}
+	if refreshErr := control.RefreshSnapshot(ctx); refreshErr != nil {
+		common.SysError("failed to refresh intelligent routing snapshot after rollout update: " + refreshErr.Error())
+	}
 	return updated, nil, nil

The same pattern applies to Publish (lines 1005-1007) and Rollback (lines 1019-1021), which already ignore only ErrIntelligentRoutingRolloutNotFound and surface every other refresh error after a committed publication.

shopspring decimal NewFromFloat NaN Inf panic behavior v1.4.0

💡 Result:

In version 1.4.0 of the shopspring/decimal library, the NewFromFloat function is explicitly designed to panic when provided with NaN (Not-a-Number), +Inf (positive infinity), or -Inf (negative infinity) as an input [1]. The library's internal implementation uses a check at the beginning of the conversion process to detect these special floating-point values [1]: if math.IsNaN(value) || math.IsInf(value, 0) { panic(fmt.Sprintf("Cannot create a Decimal from %v", value)) } This behavior has been a longstanding design choice in the library [2][3]. While there have been community requests to return an error instead of panicking to improve safety and interoperability with systems that support these values (such as PostgreSQL), maintainers have historically maintained the panic behavior to avoid breaking backward compatibility for existing users [2][3]. Users who require support for NaN or infinity must perform their own validation checks on the float64 value before passing it to NewFromFloat [4][2][3].

Reject non-finite routing values in Normalize.

NaN bypasses range checks for MaxCostMultiplier, model prices, and quality thresholds. A NaN multiplier or price reaches decimal.NewFromFloat and panics. A NaN threshold makes every candidate fail the threshold check, so the planner falls back to all eligible candidates.

Reject non-finite values before range validation.
