From c7858418a796424d2c71316fbbfbbf08f82212ff Mon Sep 17 00:00:00 2001 From: Amit Frechter <62295935+Amitfre15@users.noreply.github.com> Date: Thu, 3 Sep 2026 11:36:12 +0000 Subject: [PATCH 1/3] Feat: Add PRB-level correctness suite for AIAC eval framework (#2089) Adds a reusable precision/recall + denial-precision scorer (eval/correctness_scorer.py) and a new PRB-direct correctness suite (eval_correctness_prb marker) scoring the Policy Rules Builder's raw output against the existing 8-scenario truth-table corpus, with a zero-tolerance gate on over-grants. Also rewrites all 16 scenario policy.eval_*.md files to read like human-authored access-control text instead of exposing the pipeline's internal gate vocabulary, which the new correctness-prb spec doc and this suite now depend on as shared infrastructure alongside the existing eval_consistency/ eval_robustness suites.

Those two remain +covered exactly as `policy-eval-scenarios.md` already documents them +(`test_guardrail_conflicts.py`/`test_guardrail_injection.py`, `@pytest.mark.integration`, +`xfail`-pinned). + +## Policy-text rewrite + +As part of this ticket, all 8 scenarios' policy `.md` files (`eval/scenarios/policy.eval_*.md`, +`test/integration/policy.eval_agent_delegation.md`) and their 8 `eval/scenarios_perturbed/` +semantic siblings were rewritten to read like real human-authored access-control policy rather +than the pipeline's own internal vocabulary reflected back into the document a policy author would +supposedly have written. The previous text opened with the literal internal-modeling phrase +`"(role, scope) pair"` and organized every scenario under three headers named for the pipeline's +own three gates (`Users → agent capabilities (inbound...)`, etc.) — exposing implementation +structure in a document that, in a real deployment, a human policy author writes without any +notion of "gates" at all. Nouns were also generic ("a resource agent", "a device") rather than +scenario-domain-concrete ("the inventory agent", "irrigation valves") — a real signal loss for +`empty_descriptions` specifically, since every `Role`/`Scope` description there is deliberately +`""`, leaving the policy text as the only semantic signal available to the PRB. + +The rewrite collapses each scenario to the fewest natural sentences that state every distinct +fact once — no header labels, no restating the same fact three ways just because the pipeline +internally has three gates. When a scenario's user-facing access and the agent's own capability +are identical (the common case), one sentence covers all three gates and the PRB is trusted to +derive inbound + outbound-subject + outbound-target from it. Scenarios where the human's access +and the agent's own capability genuinely diverge (`ambiguous_clause`) or where two roles' +real access differs even though their agent access looks similar (`misleading_descriptions`, +`agent_delegation`) still get multiple sentences — that's a real fact, not pipeline-structure +mirroring. + +**No `.py` file changed as part of this rewrite.** `INBOUND_PAIRS`/`OUTBOUND_PAIRS`/ +`OUTBOUND_SUBJECT_PAIRS` truth tables, agent/tool/scope ids, and the `AGENTS`/`TOOLS`/ +`USER_ROLES` description dicts are untouched — only the natural-language `.md` policy text +changed. This is shared infrastructure: the rewritten `.md` files are read by this suite, +`policy-eval-scenarios.md`'s heavy scenarios, and both of +`policy-eval-robustness-consistency.md`'s suites (`eval_extended`/`eval_consistency`/ +`eval_robustness`) alike, since all four families read the same `policy.eval_*.md` files off disk +via `AIAC_POLICY_FILE`. The regression risk of the rewrite — that a reworded, header-free document +might produce different grant decisions than the old mechanical-template text did — is exactly +what running those other suites against the rewritten text checks (see +[Runbook](#runbook)). + +## Configuration (env) + +| Variable | Purpose | +|---|---| +| `LLM_BASE_URL` / `LLM_MODEL` / `LLM_API_KEY` | The only required variables — the suite calls the PRB directly against a real LLM endpoint. | +| `AIAC_POLICY_FILE` | Set per test call (via `monkeypatch.setenv`), pointed at the scenario's own `policy.eval_.md`. | + +No `KEYCLOAK_URL`, Keycloak admin creds, `AIAC_PDP_CONFIG_URL`/`AIAC_POLICY_STORE_URL`/ +`AIAC_PDP_POLICY_URL`, or `OPA_BIN` are read — see +[policy-eval-robustness-consistency.md § No-Keycloak design](policy-eval-robustness-consistency.md#no-keycloak-design), +which applies here unchanged. + +## Runbook + +```bash +# TDD the scorer first (pure logic, no live infra, runs in the default fast pass): +.venv/bin/pytest eval/test_correctness_scorer.py -v + +# The suite itself — needs only LLM_BASE_URL/LLM_MODEL/LLM_API_KEY, no Keycloak/opa: +.venv/bin/pytest eval/test_policy_pipeline_correctness_prb.py -m eval_correctness_prb -v -s + +# Regression-check the rewritten policy text against the suites that already depend on this +# corpus (the real risk of the rewrite — that reworded text still produces the same decisions): +.venv/bin/pytest eval/test_policy_pipeline_consistency.py -m eval_consistency -v +.venv/bin/pytest eval/test_policy_pipeline_robustness.py -m eval_robustness -v +``` + +Like every sibling suite, `require_env("LLM_BASE_URL", "LLM_MODEL", "LLM_API_KEY")` is the first +line of the parametrized test function, raising `SystemExit(2)` if any is unset/empty. + +## Relationship to other integration tests + +This is **one** integration-test spec among several indexed by the master PRD +([../PRD.md](../PRD.md), § *Integration test specifications*). + +- **Companion to, not a replacement for, [policy-eval-scenarios.md](policy-eval-scenarios.md) and + [policy-eval-robustness-consistency.md](policy-eval-robustness-consistency.md).** All three + reuse the same 8-scenario corpus and PRB entry points; each isolates a different property + (correctness with a precision/recall/denial-precision breakdown here, vs. plain grant-set + equality downstream of the full pipeline in the former, vs. consistency/robustness in the + latter). +- **New marker, registered in `pyproject.toml`** (`eval_correctness_prb`), distinct from + `eval_extended`/`eval_consistency`/`eval_robustness`, named deliberately to leave room for a + future `eval_correctness_e2e` marker (#2090) without ambiguity between the two correctness + suites' infra requirements. + +## Out of Scope + +- **Wiring into `eval/conftest.py`'s Markdown report or a committed trend log.** Deferred to + #2091. +- **End-to-end (Keycloak+OPA) correctness scoring.** Deferred to #2090 — `correctness_scorer.py` + is designed to be reusable there; the wiring itself is not this ticket's scope. +- **An under-grant tolerance threshold.** Per the originating spec, still TBD — under-grants are + tracked/reported via `record_property` and the printed summary line, never gated. +- **New scenarios.** The taxonomy cross-check above confirms the existing 8-scenario corpus + already covers every taxonomy theme; none is needed. + +## Blocked-by + +Same PRB prerequisites as +[policy-eval-robustness-consistency.md](policy-eval-robustness-consistency.md#blocked-by) — the +PRB entry points (`orchestrate_prb`, itself built on `build_role_rules`/`build_scope_rules`) and a +live LLM.
