From 13f719f137115d838ac585502941b2b1a33b3292 Mon Sep 17 00:00:00 2001 From: linhdmn Date: Mon, 21 Sep 2026 17:11:36 +0700 Subject: [PATCH 1/4] feat(systemone): the loop screens every step through a System One client (#8) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit agentloop had the guardrail *policy* (internal/experiments.Route, strict / permissive) and no transport: NewRunnerWithTypeSafeScreen existed but nothing in the service ever called it, so no run was screened and no run could say so. The transport is added where the policy already lives, as the third thin client next to internal/onegw and internal/leankg: one POST, no retry ladder, no key pool, no backend switch. The backend choice is a URL (AGENTLOOP_SYSTEMONE_URL): onegw's POST /v1/systemone by default — PRD §4.3 unchanged, onegw still owns combo/fallback/usage — or TypeSafe / a Laya sidecar directly when an operator names one. A Jev/Laya generation-provider abstraction is deliberately not built: Jev and Laya are evaluation models, not chat models, and the wire that fits both is the decision wire. - internal/systemone: Evaluate (any battery) + Screen (the guardrail battery, the same five questions typesafe_experiments.sh sends, so Go and shell score the same corpus). Both answer envelopes are read — TypeSafe's `noul` and Laya's probabilities["1"] — with no caller-side branch on which answered. - Every failure is an error, never a zero: a missing hazard or a missing severity Score would route as "pass", which is the false negative a guardrail must not produce. - internal/loop: RunnerConfig.Guardrail + RunnerConfig.Policy, the screen at the step boundary, and the verdict recorded on the step (the hazard that fired, plus the severity when the severity is what escalated it). - New exit guardrail_unavailable: a screen that could not be evaluated fails closed, and "the screen said no" is reported differently from "there was no screen". - cmd/agentloop: AGENTLOOP_SYSTEMONE_URL/_KEY/_MODEL + AGENTLOOP_GUARDRAIL_POLICY. Screening is off until a URL is set; off records no verdicts, so an unscreened deploy is distinguishable from a clean one. Verified: go test ./... and make check (fmt, vet, test, lint, prd) green; a stub /v1/systemone driven through the real binary blocks a run with exit_reason=guardrail_block and the hazard row on the step, and an unreachable URL exits guardrail_unavailable rather than passing. --- README.md | 2 +- cmd/agentloop/main.go | 58 ++++ cmd/agentloop/server_env_test.go | 53 +++- docs/JEV-INTEGRATION.md | 52 +++- docs/PRD.md | 12 +- docs/USAGE.md | 5 + internal/loop/exitreason.go | 9 +- internal/loop/runner.go | 125 ++++++--- internal/loop/runner_test.go | 9 +- internal/loop/screen.go | 68 +++++ internal/loop/screen_test.go | 173 ++++++++++++ internal/systemone/systemone.go | 381 +++++++++++++++++++++++++++ internal/systemone/systemone_test.go | 215 +++++++++++++++ 13 files changed, 1113 insertions(+), 49 deletions(-) create mode 100644 internal/loop/screen.go create mode 100644 internal/loop/screen_test.go create mode 100644 internal/systemone/systemone.go create mode 100644 internal/systemone/systemone_test.go diff --git a/README.md b/README.md index 2756b26..24ee9a7 100644 --- a/README.md +++ b/README.md @@ -12,7 +12,7 @@ goal + budget in, answer / handoff / escalation out. | What | Where | |---|---| | **How to build, run, and operate it** | [`docs/USAGE.md`](docs/USAGE.md) | -| **System One (Jev hosted · Laya local)** | [`docs/JEV-INTEGRATION.md`](docs/JEV-INTEGRATION.md) | +| **System One (Jev hosted · Laya local) — client + guardrail screen** | [`docs/JEV-INTEGRATION.md`](docs/JEV-INTEGRATION.md) | | The PRD (23 sections, 4 appendices) | [`docs/PRD.md`](docs/PRD.md) | | The canonical architecture this PRD summarizes | [`../design.md`](../design.md) — at repo root | | The runnable check the ten review loops were run by | [`docs/check-prd.py`](docs/check-prd.py) | diff --git a/cmd/agentloop/main.go b/cmd/agentloop/main.go index b2c6d37..77ba0e8 100644 --- a/cmd/agentloop/main.go +++ b/cmd/agentloop/main.go @@ -18,14 +18,23 @@ import ( "github.com/FreePeak/agentloop/internal/budget" "github.com/FreePeak/agentloop/internal/eval" + "github.com/FreePeak/agentloop/internal/experiments" "github.com/FreePeak/agentloop/internal/leankg" "github.com/FreePeak/agentloop/internal/loop" "github.com/FreePeak/agentloop/internal/onegw" "github.com/FreePeak/agentloop/internal/planner" + "github.com/FreePeak/agentloop/internal/systemone" "github.com/FreePeak/agentloop/internal/tools" "github.com/FreePeak/agentloop/internal/xdev" ) +// GuardrailClient is the loop's screening surface, redeclared here so the +// server can hold one without importing the loop package's runner types. +// internal/systemone.Client satisfies both this and loop.GuardrailClient. +type GuardrailClient interface { + Screen(ctx context.Context, state any) (map[string]float64, float64, error) +} + // Server holds the in-memory run store, the runner/gate registry, // the tool registry, the M6 eval runner that gates deploys, and the // M8 model transport shared by every run. @@ -37,6 +46,10 @@ type Server struct { tools tools.ToolRegistry evalRunner *eval.Runner model *onegw.Client + // screen is the System One guardrail transport (nil = screening off). + // One client shared by every run: it holds an HTTP connection pool, + // not per-run state. + screen GuardrailClient // sandboxDir is the workspace sandboxed turns run in; empty when no // executor is configured. sandboxDir string @@ -73,6 +86,7 @@ func NewServer() *Server { os.Getenv("AGENTLOOP_ONEGW_KEY"), envOr("AGENTLOOP_ONEGW_COMBO", "dev"), ), + screen: systemoneFromEnv(), evalRunner: eval.NewRunner(func(cfg loop.RunnerConfig) (*loop.LoopRunner, *budget.Guard, tools.ToolRegistry, error) { // Same runner the service builds, minus the model: the gate and // the planner are part of what the cases exercise, so building a @@ -112,6 +126,45 @@ func leankgFromEnv() *leankg.Client { return leankg.New(envOr("AGENTLOOP_LEANKG_URL", "http://127.0.0.1:8090")) } +// systemoneFromEnv wires the System One guardrail transport from the +// environment. +// +// AGENTLOOP_SYSTEMONE_URL endpoint root; empty disables screening +// (default when set: onegw's root) +// AGENTLOOP_SYSTEMONE_KEY bearer key; empty sends no Authorization +// header (what onegw and a local sidecar want) +// AGENTLOOP_SYSTEMONE_MODEL evaluation model, default jev-latest +// +// The URL is the whole backend choice, which is the point (PRD §4.3): point +// it at onegw (http://127.0.0.1:8080) and it owns the combo, the fallback +// chain and usage accounting; point it straight at a backend +// (https://api.typesafe.ai for Jev, http://127.0.0.1:8091 for a local Laya +// sidecar) and the same client screens without any code change. +// +// Screening is OFF until a URL is given, and off is not "pass": a run with +// no screen has no verdicts recorded, so an operator reading a trajectory +// can tell an unscreened deployment from a clean one.

Updated 2026-09-21. - **How this document is verified:** `docs/check-prd.py` asserts the PRD's own load-bearing promises (every internal § reference resolves, all 100 App. B patterns are accounted for, every FR/NFR carries a sourced why, no default row has a vague source, §6 exposes the shapes a builder needs, the parity harness behind M3 exists, the provenance sweeps are recorded). Run it before committing a change to this file; `--selftest` proves the checks can actually fail. - Deep read of both source documents for this PRD was done on 2026-09-18; all 40+ numeric figures reproduced here were taken from the report's *Numbers to know* table and the PDF's chapter bodies, not recalled. - **QC pass (2026-09-18):** a second, independent read-only sweep re-checked every claim in this PRD against the four repositories and `design.md` — endpoints, routes, config sections, tool names, role model, protocol constant and section pointers. 16 of 18 claim groups confirmed at file:line; the four that were wrong are fixed in the text and recorded in the footer.
