- Line 354: Update the “Runbook / oncall implications” heading to use the
correctly hyphenated “Runbook / on-call implications”; leave the surrounding
content unchanged.
- Line 187: When implementing the Granite Guardian client, enforce the TLS
credential rule around the verify_ssl and api_key configuration: require
certificate verification or a trusted CA bundle whenever api_key is set, and
reject configurations that disable verification while supplying the key. Allow
verify_ssl false only when no api_key is configured.

…d design The prompt guardrails spec described a standalone `guardrails:` config section with separate detectors and rules, a `src/guardrails/` package, a `DetectorBackend` protocol and a structured `ScreeningItem` payload. The detector framework that shipped under LCORE-3389 (PR lightspeed-core#2580) took a different route: Granite Guardian is a shield type in the existing `shields:` list, configured through `GraniteGuardianShieldConfiguration`, `GraniteGuardianConfig` and `RiskDefinition`, and evaluated by an `AbstractSafetyCapability`. The spec was not updated at the time, so the tickets implementing the input and output points were being reviewed against a design that no longer matched the code. Rewrite the What, Requirements, Architecture, acceptance test surface, aspect-specific concerns and implementation suggestions sections to describe the shipped design: the shield's risk selection by point, the Granite Guardian 4.1 judge prompt, logprob-based scoring against the per-risk threshold, the two evaluation paths (run_shield_moderation_v2 before RAG on the Responses-based endpoints, agent capabilities on the agent-based endpoints), and the fail-closed error handling as implemented. Keep the requirements that still apply and name the ticket that covers each open one: concurrent evaluation and per-risk latency (LCORE-3390), advisory risks via a new `blocking` flag and streaming checkpoints (LCORE-3391), the validation-error metric that currently has no callers (LCORE-4089), and skipping RAG, the main LLM call and the topic-summary call for input-blocked requests on /v1/query and /v1/streaming_query (LCORE-4090). R6 is extended to cover topic-summary calls and RAG documents in the response, because the in-agent path currently returns both for blocked queries. Move capabilities of the original design that the shipped configuration does not provide into a new "Deferred from the original design" section: the separate config section and backend protocol, the openai_moderations and llama_stack_shields backends, out-of-the-box risk ids, the boolean verdict without a threshold, fail-open and refusal-shaped detector failures, api_key_path, the concurrent input execution mode and a global violation message. Record model selection and guardian token accounting as open questions, note that the `enable_thinking` docstring points at a `ModerationConfig.thinking_enabled` setting that does not exist, and add a changelog row explaining the revision.
Advisory (non-blocking) risks were listed as requirement R4e, to be added under LCORE-3391 through a new `blocking` flag on RiskDefinition. Ask Red Hat, the consumer the output point was designed around, runs blocking-only screening, and no current consumer needs risks that record an outcome without altering the response. LCORE-3391 now covers block and pass only. Remove R4e and its acceptance-test row, drop the `blocking` flag from the key-files table, stop tying the tool point's behaviour to a per-risk blocking posture, and list advisory risks under "Deferred from the original design" together with the one field needed to add them later.
… the guardrails spec Two review nits on the spec realignment: - The configuration example now states that verify_ssl must not be false when api_key is set. The Granite Guardian client sends the key as a bearer token, so disabling certificate validation on a credentialed endpoint would let an on-path attacker capture it. The constraint is documented here so the client implementation enforces it. - "Runbook / oncall implications" is spelled "on-call".

Description
Aligns the prompt guardrails spec (
docs/design/prompt-guardrails/prompt-guardrails.md) with the design that actually shipped.The spec described a standalone
guardrails:config section with separate detectors and rules, asrc/guardrails/package and aDetectorBackendprotocol. The detector framework merged under LCORE-3389 (#2580) instead makes Granite Guardian a shield type in the existingshields:list (GraniteGuardianShieldConfiguration,GraniteGuardianConfig,RiskDefinition). The spec was not updated then, so the input and output point tickets were being reviewed against a design that no longer matched the code.What changes:
run_shield_moderation_v2before RAG on/v1/responsesand/rlsapi; agent capabilities on/v1/queryand/v1/streaming_query).blockingflag and streaming checkpoints (LCORE-3391), the validation-error metric, which currently has no callers (LCORE-4089), and skipping RAG / main LLM / topic summary for input-blocked requests on the agent-based endpoints (LCORE-4090).openai_moderationsandllama_stack_shieldsbackends, out-of-the-box risk ids, a threshold-less boolean verdict, fail-open and refusal-shaped detector failures,api_key_path, the concurrent input execution mode and a global violation message.enable_thinkingdocstring references aModerationConfig.thinking_enabledsetting that does not exist; a changelog row.Type of change
