Feat: Policy Model ALLOW/DENY (positive + negative) rules

[anatolykoyfman]

Summary

Adds negative (DENY) role→scope rules alongside the existing positive (ALLOW) ones, end-to-end across the AIAC policy stack. Until now the stack was a pure allowlist: a PolicyRule(role, scope) was always a grant and everything ungranted was implicitly unreachable (default allow := false). There was no first-class way to say "this role must not reach this scope."

Policy rules are now two-sided: every (role, scope) tuple carries an effect (Allow/Deny, default Allow), and both kinds are stored side by side as first-class facts. A DENY rule is a durable prohibition that subtracts from what the ALLOW rules grant, honored at every gate (inbound subject, inbound source, outbound subject, outbound target). Generated Rego applies deny-overrides: a request is allowed only if some ALLOW gate passes and no DENY gate matches.

The two-layer model (SPM source-of-truth → derived APM → generated Rego) keeps its shape; each layer gains a parallel deny track.

What changed, by layer

• Policy model (policy/model/models.py) — new RuleEffect string enum; PolicyRule gains effect (dedup identity becomes (role.id, scope.id, effect)). ServicePolicyModel splits inbound_rules into parallel inbound_allow_rules / inbound_deny_rules. AgentPolicyModel splits into the 8 entity×effect rule lists and target_{allow,deny}_scopes, and gains a per-agent default_effect (defaults to DENY, reproducing today's least-privilege behavior).
• Policy Computation Engine (policy/computation/engine.py) — routes and derives rules by effect, threading default_effect from the PCE onto the derived APMs.
• Policy Model Store + transport (policy/model_store/) — split-field references across library API and service.
• PDP OPA Rego generator (pdp/service/policy/opa/rego.py) — emits separate ALLOW/DENY gates with deny-overrides at every gate, plus the per-agent default_effect (rendered into each generated policy), with an identifier rename and refreshed fixtures.
• Policy Rules Builder — teaches the PRB to extract DENY rules from natural-language policy text while keeping the ALLOW grant path clean; PRB itself stays allow-only for storage (deny-extraction wiring is a deferred follow-up).
• Onboarding / event-bus / controller — default_effect threaded through the onboarding orchestrator, event-bus consumer, and controller routes.
• Docs — specs, PRDs, and the Policy Model Store state-reset runbook reconciled to the two-sided model and the per-agent default_effect.

Design notes

• No-conflict assumption: no (role, scope) is ever both ALLOW and DENY for the same subject, so there's no precedence/tie-break — DENY simply removes.
• default_effect terminology: there is one field. It lives on AgentPolicyModel (hence "per-agent"); the PDP renders it into each generated OPA policy (hence "per-policy" in the writer bullet). Same concept, one authority — not a second knob. Distinct from PolicyRule.effect's own ALLOW default (that only labels an explicitly-constructed-but-unlabeled rule; default_effect decides the fallback for pairs no rule mentions).
• Source-side deny reach (security property): the inbound source_allow_ok platform/no-client_id bypass sets only the allow gate; allow still requires not source_deny_ok and not subject_deny_ok, so a bypassed source is not immune to a subject-side deny. The one structural limit: a caller presenting no client_id (pure end-user traffic) can never trip the source-side deny (source_roles[client_id] is undefined), so DENY cannot revoke source-side trust there. Deliberate — dropping the bypass would deny platform-fronted end-user traffic. Documented in pdp-policy-writer-opa.md.
• No back-compat: the Policy Model Store state is nuked & re-seeded (ConfigDict(extra='ignore') would silently drop renamed fields on an old record). See the state-reset runbook.

Testing

• .cortex/bin/python -m pytest test/ -m "not integration" → 602 passed, 155 deselected (includes the new DENY cases).
• Generated Rego enforces DENY alongside ALLOW (deny-overrides) at every gate; covered by the OPA writer and aiac.pdp.library unit tests plus the denyworld integration scenario.

Scope

Net diff is confined to aiac/ (56 files). The feature is built on top of unreleased AIAC phase-2 foundations (OPA plugin integration, event broker) present on this branch; those land together here as part of the same aiac incremental change.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 6b347

The PR adds deny-overrides policy behavior, but a conflicting role/scope pair can still be generated and cause incorrect denials, while some onboarding and rebuild paths can ignore or reset the configured default behavior. These are bounded but concrete merge-readiness risks that need fixes or explicit owner acceptance; the remaining issues are localized documentation, lint, and test-fixture cleanup.

Clarification regarding defaults and allow vs deny behavior:

There are two completely separate concepts in this PR that both happen to use the word "default". They apply at different levels of the system.

1. PolicyRule.effect default → Allow

What it answers: "If someone writes a PolicyRule(role, scope) without specifying an effect, what do they get?"

This is a backward-compatibility default for the Python object, not a security posture. Every existing caller in the codebase that constructs a PolicyRule today only ever means a grant. So effect: RuleEffect = RuleEffect.ALLOW just means "old code that doesn't know about DENY yet keeps producing exactly the grants it always produced." It has nothing to do with what happens to unmentioned roles/scopes — it only decides what an explicitly-constructed-but-unlabeled rule means.

2. AgentPolicyModel.default_effect default → Deny

What it answers: "For a (role, scope) pair that has no rule at all — neither an ALLOW nor a DENY — what does the deployed Rego do?"

This is the actual security posture / fail-safe default, applied at the OPA policy-generation level. The doc spells out three states per pair:

• explicitly ALLOWed → allowed
• explicitly DENYed → denied
• unspecified (no rule mentions it) → resolves to default_effect

default_effect = Deny (the default) reproduces today's default allow := false — nothing is reachable unless some rule grants it. This is least-privilege and is what the system does today, unchanged. default_effect = Allow is an opt-in mode where everything is reachable unless an explicit DENY rule blocks it — a permissive posture, only used deliberately (e.g. the "denyworld" test scenario).

So: rule 1's default only affects rules you write without an explicit effect (defaults to grant). Rule #2's default affects everything you don't write a rule for at all (defaults to deny). They're not in tension — they answer different questions, one about an individual object's implicit label, the other about the whole system's fallback when no rule exists.

3. "Deny-overrides" — not a default at all

This is just the conflict-resolution rule applied whenever both an ALLOW and a DENY gate are present for the same request: DENY always wins over ALLOW. It's orthogonal to both defaults above — it only matters once you already have competing rules in play, regardless of what default_effect is set to. That's why the summary phrases it as "allowed only if some ALLOW gate passes and no DENY gate matches" — that's the per-request evaluation logic, not a fallback value.

Putting it together with an example

For a role/scope pair under the default configuration (default_effect = Deny):

• No rule at all → DENY (rule 2's fallback)
• Only an ALLOW rule → ALLOW
• Only a DENY rule → DENY
• Both ALLOW and DENY rules → DENY (deny-overrides wins) — though per the PR's "no-conflict assumption," this case is treated as a contradiction and normally shouldn't happen if rules go through the Policy Rules Builder.

The "per-policy default_effect" and "per-agent default_effect" phrasing in the PR body both refer to the same field (§2 above) — it's called "per-agent" because it lives on AgentPolicyModel, and "per-policy" loosely because each agent's policy can independently choose its own fallback. That's not a third concept, just imprecise phrasing across two sections of the PR description — worth flagging as a documentation nit, since a reader skimming the summary vs. the "design notes" section could reasonably come away confused.

[abigailgold]

Suggestions (non-blocking)

#	File	Area	Finding
1	aiac/src/aiac/policy/computation/engine.py (_decommission, _derive)	Design gap, documented	_decommission() calls _derive(agent_id, spm) without passing default_effect, so any agent re-derived as a side effect of an unrelated service's decommission silently resets from ALLOW back to DENY (least-privilege). This is explicitly documented as a known "non-durability caveat" (comment + 3 doc references) rather than a silent bug, and the real fix (persisting default_effect on the SPM) is called out as future work. Still, this is a genuine operational trap: an admin who set default_effect=ALLOW on an agent could see it silently flip back to DENY after an unrelated tool decommission elsewhere in the system, with no warning or audit log entry at the point of the reset. Recommend: at minimum, log a warning when _derive resets a previously-ALLOW agent's default_effect to DENY during an unrelated recompute, so operators have a signal rather than a silent security-posture change.
2	aiac/src/aiac/pdp/service/policy/opa/rego.py (inbound source gate)	Security-relevant design choice	The inbound-source ALLOW gate's platform-client bypass (not input.identity.client_id / platform_clients membership) is not subject to DENY override — a DENY rule against a platform client's role would never fire, since the bypass short-circuits before the role-based allow/deny gates are consulted. This is commented as intentional but is a meaningful trust decision (system/platform clients are always allowed regardless of any DENY rule targeting them). Recommend the PR description or a spec doc explicitly state this as a documented security property (i.e., "DENY rules cannot revoke platform-client trust") so it isn't discovered as a surprise later — right now it's only in a code comment inside rego.py.
3	Policy Rules Builder / PCE / model layer boundary	Documented but worth surfacing	The "no-conflict" invariant ((role, scope) is never both ALLOW and DENY) is enforced only by the PRB's LLM-audited pipeline. Any code path that constructs PolicyRule objects directly and calls compute_and_apply/PCE APIs without going through the PRB (e.g., a future admin API, a migration script, or a test helper) has zero validation against contradictory rules — the PCE and Rego generator both silently trust the invariant and "never reconcile" a violation. Since this is explicitly listed as a deferred follow-up in the PR body, no action is required now, but recommend opening/linking a tracking issue (if not already covered by "ALLOW/DENY conflict/precedence resolution" in the tracker) specifically for hardening the PCE/model layer itself, not just the PRB's authoring path — so any non-PRB caller is protected too.

[clawgenti]

Solid implementation of deny-overrides ALLOW/DENY across the full policy stack — PolicyRule.effect, split SPM/APM rule lists, PCE routing and derivation, Rego generator, PRB contradiction detection, and the schema-break runbook. All CI checks pass. Two notes below.

default_effect non-durability: no tracking issue linked.

The caveat is documented clearly, but the consequence is operationally significant: if AIAC_DEFAULT_EFFECT=Allow is set at onboarding time and a later, unrelated role-update recompute hits the same agent, its APM silently reverts to DENY until the next onboarding. Consider opening a follow-up issue to evaluate persisting default_effect on ServicePolicyModel (or an equivalent SPM-level field), or at least adding a log warning in _derive when it stamps a DENY over an APM that may have previously been ALLOW — as-is there's no observable signal when the revert happens.

[clawgenti]

_derive_outbound_subject called inside the per-effect loop — double-scan when both allow and deny edges exist for the same (role, scope).

_derive_outbound iterates over (ALLOW, ...) then (DENY, ...). For a role that has edges in both lists for the same target scope, _derive_outbound_subject is called twice with identical (apm, stored, scope). It re-scans all of stored's user edges for that scope both times; _add_rule deduplication keeps correctness, but the second scan is pure overhead. Since _derive_outbound_subject is effect-agnostic over stored (it splits by effect internally), it could be hoisted above the for effect, ... loop and called once per matched scope. Functionally fine as-is, but worth tidying.

[clawgenti]

AIAC_DEFAULT_EFFECT env var has no corresponding entry in Helm values or k8s manifests.

This is the operator-facing toggle for permissive-default onboarding, but it appears only in routes.py and in comments — there's no values.yaml entry or ConfigMap key that makes it discoverable. Operators relying on the integration harness approach (#149) will need out-of-band knowledge that this env var exists and what values it accepts ("Allow" / "Deny"). Consider adding a commented-out or defaulted entry in the relevant Helm chart / ConfigMap to make the knob self-documenting at the deployment level.

[clawgenti]

Substantial and well-architected feature: adds a RuleEffect enum (Allow/Deny) throughout the policy model stack — PolicyRule, ServicePolicyModel (split inbound_allow_rules/inbound_deny_rules), AgentPolicyModel (eight entity×effect rule lists, split target maps), PCE routing/derivation, Rego generator (deny-overrides with symmetric gates), and PRB (explicit/exclusive deny extraction, PolicyContradictionError). Backward-compatibility is preserved via pydantic defaults and the DENY-defaulted default_effect parameter. Two observations worth addressing before merge:

Finding 1 — NATS path silently ignores AIAC_DEFAULT_EFFECT: The HTTP /apply/service/{id} route consults _default_effect_from_env() and threads the result to onboard_service. The NATS consumer (_handle, consumer.py:54) calls onboard_service(subject[...]) with no parameter, so it always uses the DENY default regardless of the env var. The env var name and the surrounding comment imply a deployment-wide setting, but a NATS-triggered onboarding in the same pod will silently produce DENY-default Rego even when the operator set AIAC_DEFAULT_EFFECT=Allow. The asymmetry is operational but not obvious — at minimum the env var comment and/or the runbook should call out that this setting only applies to the HTTP-triggered onboarding path.

Finding 2 — test_handle_routes_service_subject_to_onboard_service uses RuleEffect.ALLOW as mock return but consumer.py:54 will always yield DENY in production: The test asserts _handle passes the 3-tuple verbatim from onboard_service, which is the right contract to check. However, using ALLOW as the mock value means the test doesn't catch a future regression where someone adds an env-var lookup inside _handle for the NATS path and accidentally does the wrong thing. A second parametrized test variant with the real no-arg call signature (verifying onboard.assert_called_once_with("svc-1") and result[2] == RuleEffect.DENY) would pin the intended NATS-always-DENY behavior.

This calls onboard_service with no default_effect parameter, so the NATS-triggered onboarding path always uses RuleEffect.DENY regardless of the AIAC_DEFAULT_EFFECT env var set on the controller pod. The HTTP route reads the env via _default_effect_from_env(), but this path never does — making the env var a per-path (not deployment-wide) setting. Worth a comment here noting the intentional asymmetry, and a mention in the runbook or env var doc so operators aren't surprised.

[clawgenti]

Using RuleEffect.ALLOW as the mock return value correctly tests 3-tuple passthrough, but it does not pin the real production behavior: the live NATS call at consumer.py:54 passes no default_effect and therefore always yields DENY. Consider adding a second assertion or a complementary test that calls _handle with a real (non-mocked) onboard_service stub that returns ([], False, RuleEffect.DENY) and asserts result[2] is RuleEffect.DENY, to document that NATS-triggered onboarding is always least-privilege regardless of env.

[anatolykoyfman]

Thanks @clawgenti and @abigailgold — helpful review. Dispositions below; addressed in 6b347d8 + PR-body updates.

Done in this PR

• Source-side deny / platform bypass (abigail point 2): Promoted to an explicit security property in pdp-policy-writer-opa.md and the PR body. One clarification on the mechanism: the bypass only sets source_allow_ok — the final allow still requires not source_deny_ok and not subject_deny_ok, so a bypassed source is not immune to a subject-side deny. The single structural limit is narrower than "platform clients are always allowed": a caller presenting no client_id (pure end-user traffic) can never trip the source-side deny, because source_roles[client_id] is undefined. That's deliberate (dropping the bypass would deny platform-fronted end-user traffic).
• AIAC_DEFAULT_EFFECT discoverability (clawgenti point 3): Added a commented-out env entry + note in agent-deployment.yaml. Framed as the integration-harness knob (feat: migrate demo-ui.md from demo realm to kagenti realm #149) rather than a first-class operator feature, and noting it isn't persisted on the SPM — so it's discoverable at the deployment level without over-promising support.
• "per-policy" vs "per-agent" phrasing (abigail): Unified in the PR body — one field on AgentPolicyModel, rendered per generated policy by the PDP; added a design note distinguishing it from PolicyRule.effect's own default.

Tracked as follow-ups (not in this PR)

• default_effect non-durability (clawgenti point 1 / abigail point 1): Agreed it's an operational trap — worth stressing it fails closed (reverts toward DENY/least-privilege), so it's operability, not a security hole. On the "log a warning on revert" suggestion: _derive rebuilds the APM from scratch and has no knowledge of the prior default_effect, so detecting a revert means an extra PDP read-back on every recompute; I'd rather do the real fix. Opened Follow-up: Persist default_effect on ServicePolicyModel (durability across re-derivation) rossoctl#2475 to persist default_effect on ServicePolicyModel.
• PCE/model-layer conflict hardening for non-PRB callers (abigail point 3): Already tracked by Follow-up: ALLOW/DENY conflict + precedence resolution rossoctl#2435 (ALLOW/DENY conflict + precedence resolution), whose scope explicitly spans model, PCE derivation, and generated Rego — i.e. the layer itself, not only the PRB authoring path. Linked from the PR body.

Declined

• _derive_outbound_subject double-scan (clawgenti point 2): The second scan only occurs when the same (role, scope) has both an ALLOW and DENY outbound edge — precisely the case the no-conflict invariant precludes — and _add_rule dedups, so it's correct and effectively unreachable. Leaving as-is to avoid churn.

Use both target scope maps to select the target service.

A policy with only target_deny_scopes has no target_allow_scopes key. This code then aborts before it can validate the explicit deny.

Keep only one AuthorizationPolicy document.

The file continues with a second top-level policy after this added resource. This duplicates keys such as apiVersion, kind, metadata, and spec in one YAML document. YAML linting rejects duplicate keys, and a permissive parser can retain the obsolete policy instead.

Remove the trailing legacy policy block. As per coding guidelines, “Ensure YAML configuration is valid and passes YAML linting.”

Correct the APM compatibility claim.

Line 151 says that the AgentPolicyModel shape is unchanged. This PR replaces rule-list and target-map fields with split fields and documents hard renames without aliases. A consumer that sends legacy fields can have them silently ignored and produce an incomplete policy. State that consumers must migrate to the split schema.

Guard the approved-overlap path so no pair is emitted as both ALLOW and DENY.

_audit raises only when verdict.contradictions is non-empty. If the auditor returns approved=True with an empty contradictions list while state["conflict_names"] is non-empty, the graph proceeds to build. build then emits PolicyRule(..., effect=ALLOW) and PolicyRule(..., effect=DENY) for the same (role, scope) pair, because granted and denied both contain that candidate name.

The specification states the PRB must guarantee this never happens (aiac/docs/specs/components/aiac-agent/policy-rules-builder.md, lines 248-249). Deny-overrides makes the runtime outcome fail-closed, so the impact is a broken producer invariant rather than a permissive bypass.

Treat an approval that still carries unresolved conflict names as a contradiction, or reject it back into the retry loop.

Remove the duplicated module header.

This block repeats the module docstring and the json / MagicMock imports that already exist above line 22. Two effects follow:

• The triple-quoted string at lines 23-39 is not a docstring. import pytest at line 22 precedes it, so it is a dead string expression.
• Ruff reports E402 for lines 41 and 42, so the lint gate fails on this file.

Delete the duplicated docstring and the duplicate imports. Add pytest to the existing import block at the top of the file.

🧹 Proposed fix

-import pytest
-"""Unit tests for aiac.pdp.service.policy.opa.main.
-
-Targets the always-on Custom Resource writer. The module builds a
-``CustomObjectsApi`` at import (kube-config load is guarded, so import needs no
-cluster); every test patches that module-level ``_api`` with a ``MagicMock`` so
-no real Kubernetes API is contacted. The additive ``POLICY_WRITER_DUMP_REGO``
-local-dump toggle is covered here too (it never gates or replaces the CR write).
-
-Note on the delete-by-id endpoint: its route param ``{agent_id}`` is a single
-path segment, and a valid namespaced id (``<ns>/<name>`` or a SPIFFE URI) carries
-slashes. The library client percent-encodes them and the ASGI server decodes the
-segment back, but the ``TestClient``/httpx transport collapses ``%2F`` -> ``/``
-before the request is sent, so a namespaced id cannot reach the param through
-``TestClient``. Those cases therefore call the route handler function directly
-(the FastAPI decorators leave the functions callable), which still exercises the
-full write + error-mapping path through the mocked ``_api``.
