From b20ea9a775f75f4c240c4e016be62f0ffe2a65ee Mon Sep 17 00:00:00 2001 From: Dimitris Poulopoulos Date: Sun, 13 Sep 2026 12:16:23 +0300 Subject: [PATCH 01/17] refactor(guardrails): read parameter specs by stage Split the stage filter out of `_parameter_specs` into `_specs_for_stage`, which takes the stage it wants. The validate stage was hardcoded because the guardrails service owns the constructor, so only validate parameters could ever be sent. A catalog of the guardrails this gateway runs itself needs the create stage too. No behavior change. `_parameter_specs` keeps its signature and its validate-only answer.

The registry imports nothing but its own leaves, and a guardrail's backend is probed with `find_spec` rather than constructed, so listing the catalog never loads torch. Both stages, because a guardrail this gateway constructs itself has no operator YAML fixing its constructor. That is where a vendor API key lives. It is also where most of the detail is: only 22 of the 40 guardrails take a validate parameter at all. `runnable` says whether the modules a guardrail needs are installed here, and `missing_extra` names the one extra that would fix it. A guardrail this gateway holds no backend information about reports neither, because a guess about an unknown guardrail is worse than an honest gap. Adds `storable` to the shared parameter model, false for a secret typed json. Upstream uses that shape for a live object, such as a boto3 session or an IBM API client, which cannot be written down. Nothing reads this yet.

Nothing routes to it yet. The store that supplies its arguments and the request path that chooses it come next. Both create and validate are synchronous upstream, and create loads model weights, so both run in a worker thread. The build is shielded: a thread cannot be cancelled, so a model that outlives the deadline is kept rather than reloaded by every later request. Built guardrails are cached by class and a digest of their constructor arguments, and evict() drops one by profile name so a store write can retire a stale instance. Calls go through AnyGuardrail.evaluate rather than validate directly. The 40 guardrails do not share one signature, and evaluate holds the mapping table for all of them. Every failure raises the existing GuardrailsNotReachableError, so the fail-open and fail-closed branch governs an in-process guardrail unchanged and the caller learns only the profile name. A vendor exception's text is not carried, because an SDK can echo the arguments it was handed and those hold the API key.

The runner makes both false. Restate what the dependency is for, keeping the part that still holds: no extra is taken, because the catalog reads an import-free registry and the nine hosted-API guardrails build on the base install alone.

This is the row that replaces it: named by the profile a caller sends, holding the any_guardrail class plus the arguments to build and call it. Constructor arguments are split by the catalog's secret flag rather than by a column per secret. The 40 guardrails do not share a secret shape: bedrock takes three, any_llm none, and one added upstream tomorrow may need four. So the plain ones go in a JSON column and every secret goes in one encrypted map, which costs no migration when that shape changes. Nothing reads the table yet.

A stored guardrail of the same name wins. It is not only a fallback. Hybrid mode skips init_db, mounts no management router and serves no dashboard, so it has no table to read and no page to write one on, yet caller guardrails still run there. The block is the only way a hybrid gateway defines a guardrail it runs itself. Validated at load, because a guardrail that will not build is one a request discovers by failing closed. An argument no guardrail takes is refused, since none of the 40 accepts **kwargs and it would otherwise be a TypeError at build time with nothing naming the typo. An argument upstream reads from the environment when absent is not demanded. The registry is imported inside the validators rather than at module scope: reading it costs about 90ms, core.config is imported by every entry point, and a deployment with no block should not pay for a question it never asks.

It holds asyncio locks and tasks that bind to the loop that first touches them, so an instance built at import would outlive a lifespan restart and fail from inside asyncio under the next loop.

The map is replaced rather than merged on a write, which is what makes a secret removable. A value resubmitted as the redaction mask keeps what is stored, since an editor is shown three asterisks and sends the whole object back. A mask with nothing behind it is refused, because that is the one case where the caller believes they are keeping a secret that does not exist. Changing the class alone re-splits the stored arguments under the new one, so the split can never be left describing the wrong guardrail. No in-memory overlay: nothing on the request path reads a definition yet, so there is no synchronous read to serve from a cache. What this gives that work is a definition builder for each source. The config validator grows the matching rule for a secret typed json, which wants a live object that neither a row nor a YAML file can hold.

Same shape as the search-tool sibling: operator-gated, standalone-only, config entries reported beside the stored rows and read-only there. One thing differs, and it follows from guardrails not sharing a secret shape. A caller sends one create_kwargs map mixing arguments and credentials, and a read gives back the plain half as stored plus a map of secret names to the mask. Every write evicts the profile from the runner. Without that an edited guardrail keeps answering from the instance built out of its old arguments, and the model those arguments loaded is never released, since the runner drops an entry only when no profile resolves to it. The test route answers ok: false with the reason rather than an error status. An operator asked whether the definition works, and "it does not, and here is why" is that answer. A disabled guardrail is still testable, since checking one before turning it on is the point.

A guardrail defined this way is a row Otari owns rather than an entry +in a file the guardrails service reads, so adding one takes no restart. + +`GET /api/v1/tool-settings/guardrails/catalog` lists every guardrail this build +ships, with both stages of arguments: `create` for the constructor, where a +vendor API key lives, and `validate` for the per-call ones.

Send a secret back as `"***"` to keep it, a new value to +rotate it, or leave it out to remove it. `POST /{name}/test` runs the guardrail +once against a sample input, so a definition can be checked before anything +relies on it, including one that is not enabled yet. + +A few arguments cannot be stored. Upstream lets a caller pass an already-built +client object for `boto3_session` or `api_client`, and no database can hold a +live connection, so those are refused.

A stored guardrail wins over a file entry of +the same name. In hybrid mode the file is the only source, because a hybrid +gateway keeps no local database. + +Rotating `OTARI_SECRET_KEY` works the same way it does for providers: set it to +`new,old`, restart, call `POST /api/v1/guardrail-credentials/reencrypt` alongside +the provider and search-tool endpoints, then drop the old key and restart again. +A guardrail whose secrets no longer decrypt is reported with +`"decryptable": false` rather than looking like one with no secrets at all. + ### How the layers compose Three layers can name a guardrail: the caller's request, the caller's From 036a27a0bd606cd1ea80454b356f9ad8badf6c91 Mon Sep 17 00:00:00 2001 From: Dimitris Poulopoulos Date: Mon, 14 Sep 2026 13:10:34 +0300 Subject: [PATCH 12/17] refactor(dashboard): lift the guardrail parameter form into its own module The hook that seeds a parameter form from a spec list, validates it on submit and builds the kwargs back is the same hook a form defining a locally-run guardrail needs.

So the form asks for the task first, and the second control offers only the guardrails that do it. Both lists are derived from the catalog rather than written down, the count in the help line included: this build ships forty guardrails and the next ships more. Two things are written down. The task copy, because 'general_judge' is not a sentence an operator should decode. And the order the tasks are offered in, because sorting by name or by count would shuffle the common ones as the catalog grows. What can run here sorts first. On a default install thirteen of the eighteen prompt-injection guardrails want a Python extra that is not present, so an alphabetical list opens on rows nobody can use. The rest stay in the list, dimmed and naming the extra, because an absent row says nothing at all.
