Reconfigure the aiac/ engineering-skills issue tracker from upstream rossoctl/cortex back to the s-and-p-team/cortex fork (origin). Rewrite docs/agents/issue-tracker.md to scope gh operations to the fork, record the fork's deleteIssue/createPullRequest account limitation, and drop the rossoctl AIAC Project #11 references. Update the CLAUDE.md Agent skills one-liner to match. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>

Update the Policy Rules Builder spec with the settled error-handling design (handoff 03): - Add an Exceptions section covering the five graph exceptions plus the externally-raised PolicyConflictError, with single-entity HTTP status, async retry class, and sanitization; state the HTTP-vs-retry-class decoupling explicitly. - Rewrite LLM + retries with dedicated knobs (LLM_MAX_RETRIES, LLM_RETRY_BACKOFF_MIN, LLM_RETRY_BACKOFF_MAX) and the two _structured_call raise outcomes (LLMAccessError vs UnparseableLLMResponseError); keep LLM_REQUEST_TIMEOUT and the max_retries=0 client note. - Point the Contradiction contract at the UC1 aggregation into PolicyConflictError / ConflictReport. - Update the Configuration table with the new LLM_* knobs.

Document the net-new teardown + disable capability the UC1 compensating rollback depends on, per issue #174 (handoff 05). library-idp.md: add Configuration.delete_service_role, delete_service_scope, unset_service_type, and set_service_enabled with contracts (unmap-then-delete order; read-merge unset; enabled writer); a Shared-object safety note (create-or-reuse-by-name -> delete only what this service created and nothing else references); and the Service.enabled writer/read path. idp-configuration-service.md: add DELETE /services/{id}/roles/{roleId}, DELETE /services/{id}/scopes/{scopeId}, unset-type behavior, and POST /services/{id}/enabled, each mapped to its Keycloak admin op with shared-object safety called out. Spec-only; implementation + tests are handoff 06. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>

Single-call HTTP wrappers on the existing _request/run_upstream transport: delete_service_role, delete_service_scope, unset_service_type (empty-string clear), set_service_enabled (writer for Service.enabled). Per the authoritative specs the library is a thin client, so unmap-then-delete ordering and the shared-object guard are enforced service-side (#177/#178). 21 unit tests at the Configuration seam.

Four endpoints on the IdP Configuration Service backed by Keycloak admin: DELETE /services/{id}/roles/{roleId} and .../scopes/{scopeId} (unmap-then-delete order), POST /services/{id}/type accepting empty-string clear, POST /services/{id}/enabled. Keycloak errors -> 502; missing/invalid bodies -> 422. 12 endpoint tests at the route-handler seam mocking the admin client. Shared-object guard deferred to #178.

Service-side guard between unmap and delete in both DELETE handlers: after unmapping the caller, skip deleting the realm role / client scope when it is still referenced by another subject/client (via get_realm_role_members / the scope-owner index); solely-owned objects still deleted. 2 new tests; 2 of #177's ordering tests updated to stub the reference-check as solely-owned.

Add UnparseableLLMResponseError(PolicyRulesBuilderBaseError). On transient exhaustion raise LLMAccessError (was dead); on non-transient parse/validation error raise UnparseableLLMResponseError. Both use static messages (no endpoint/host/key leak) with the original chained via __cause__. Retry cadence, is_transient, LLM_REQUEST_TIMEOUT and client max_retries=0 unchanged. New seam tests + 2 stale transport tests updated to the typed behavior. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>
_llm_retry_config() reads LLM_MAX_RETRIES (3), LLM_RETRY_BACKOFF_MIN (1), LLM_RETRY_BACKOFF_MAX (30) via a tolerant _env_number helper mirroring _request_timeout. _structured_call's Retrying loop now uses them and no longer reads the shared UPSTREAM_MAX_RETRIES, which stays for the IdP/MCP/K8s seams. #165's typed-raise/reraise semantics untouched; its cadence tests migrated to LLM_MAX_RETRIES. Decoupling proven by test. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>
Add LLM_MAX_RETRIES (3), LLM_RETRY_BACKOFF_MIN (1), LLM_RETRY_BACKOFF_MAX (30) to the aiac-agent-config ConfigMap, consumed by the PRB seam (graph._llm_retry_config from #166). UPSTREAM_MAX_RETRIES retained and kept scoped to the IdP/MCP/K8s transport seams (no conflation). Manifest-only (no central settings loader exists).

…ld (#168) build() no longer aborts on the first PolicyContradictionError: a _guarded() helper catches contradictions per focal and continues the fan-out, then unions them (report_from_contradictions rows, withheld focals as Conflict rows) with detect_conflicts' structural survey into one ConflictReport via from_survey; non-empty -> best-effort enrich_report -> raise the existing PolicyConflictError(report). Hard failures (PolicyRulesBuilderError/LLMAccessError/UnparseableLLMResponseError) short-circuit and propagate for Orchestrator rollback. Clean run returns rules unchanged.

New src/aiac/agent/shared/error_logging.py: log_by_type(exc) routes each PRB exception to its per-persona named logger (aiac.onboarding.builder / llm_access / llm_response / contradiction) at ERROR with full context via exc_info (traceback + chained cause) to stdout; MRO walk so subclasses route to an ancestor, unmapped falls back to aiac.onboarding. Both PolicyContradictionError and the report-carrying PolicyConflictError route to aiac.onboarding.contradiction.

Replace the blanket except Exception in _dispatch with isinstance type classification: permanent {PolicyConflictError, PolicyContradictionError, PolicyRulesBuilderError, UnparseableLLMResponseError} -> DLQ (aiac.apply.dlq) + term() immediately (no redelivery); retryable {LLMAccessError} and unknown/transient -> left unacked to redeliver up to MAX_DELIVER (5), then DLQ. Every failure logged exactly once via log_by_type. Reuses the existing jetstream publish + term primitives.

…-enable (#171) onboard_service wraps provision -> build; on any of {PolicyConflictError, PolicyRulesBuilderError, LLMAccessError, UnparseableLLMResponseError} it runs a compensating rollback (delete created roles/scopes, unset client type, then set_service_enabled(service, False) as the failed-service marker last), logs the actions at info, then re-raises. Success path sets enabled=true (idempotent). provision_service now returns a created-manifest (created_roles/created_scopes via a pre-create name snapshot) so rollback deletes only what this run created; reused-by-name entities survive. Rollback/disable are UC1-only; provision (pre-build) failures propagate without rollback. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>

The compensating-rollback log records interpolated the user-controlled service_id (and created role/scope names) with %s, so a crafted value carrying CR/LF could forge or inject extra log lines. Route every user-influenced value through a _loggable() helper that strips \r and \n before logging. Addresses CodeQL alerts py/log-injection rossoctl#198-rossoctl#201.

- Around line 4-5: Update the instructions around the `gh` CLI so `-R
s-and-p-team/cortex` is used only for repository-scoped issue and label
operations; use `--owner s-and-p-team` for project discovery, `--project-id` for
documented project item updates, and `gh auth refresh -s project` for account
authentication.
In `@aiac/docs/specs/components/idp-configuration-service.md`:
- Line 30: Remove the unsupported DELETE alternative from the service-type
endpoint specification, leaving POST as the documented method unless a
corresponding DELETE route is implemented in main.py.
In `@aiac/k8s/agent-deployment.yaml`:
- Around line 25-31: Update the retry configuration comment above
LLM_MAX_RETRIES, LLM_RETRY_BACKOFF_MIN, and LLM_RETRY_BACKOFF_MAX so it
explicitly identifies LLM_MAX_RETRIES as the LLM retry limit and distinguishes
it from UPSTREAM_MAX_RETRIES, which only governs transport retries.
In `@aiac/src/aiac/agent/uc/onboarding/orchestrator.py`:
- Around line 70-77: Update _rollback so each teardown
operation—delete_service_role, delete_service_scope, and unset_service_type—runs
as best effort without preventing later cleanup; preserve the original build
error when teardown raises, and ensure set_service_enabled(service, False)
executes in a finally path even if teardown fails.
- Around line 110-111: Remove the client re-enablement from onboard_service, and
add it only after compute_and_apply completes successfully in both the HTTP
route and the NATS service consumer. Preserve the existing failure behavior so
PCE errors leave the client disabled.
In `@aiac/src/aiac/agent/uc/onboarding/provision/nodes.py`:
- Around line 290-291: Serialize the complete onboarding lifecycle per service
by adding a per-service lock around onboard_service, covering policy building,
provisioning, and rollback. Ensure concurrent calls for the same service_id
cannot overlap, while allowing independent services to proceed concurrently; do
not limit the lock to provision_service.
In `@aiac/src/aiac/idp/service/configuration/keycloak/main.py`:
- Around line 428-429: Update the role teardown flow around get_realm_role_by_id
and delete_realm_roles_of_user to treat KeycloakGetError with response_code 404
as a successful idempotent result, continuing _rollback so client.type is unset
and the client is disabled; preserve propagation of other errors.
- Around line 506-507: Update the teardown endpoint around the Keycloak delete
calls so 404 KeycloakDeleteError responses from both
delete_client_default_client_scope() and delete_client_scope() are treated as
successful no-ops, allowing unset_service_type() and set_service_enabled(...,
False) to run. Preserve the existing 502 response for other Keycloak errors.

…bit) Addresses CodeRabbit review on PR rossoctl#884: - delete_role_from_service / delete_scope_from_service now treat a Keycloak 404 (already-gone role/scope/mapping) as idempotent success instead of 502, so a UC1 rollback retry proceeds to unset-type + disable rather than aborting. The spec already documented this idempotency; the code now matches. (+tests) - Spec: drop the unimplemented 'DELETE /services/{id}/type' alternative (only POST-empty is registered). - ConfigMap: fix the LLM_REQUEST_TIMEOUT comment to cite LLM_MAX_RETRIES, not UPSTREAM_MAX_RETRIES (the LLM seam no longer uses the shared knob). - issue-tracker doc: clarify -R is for repo-scoped issue/label ops; Projects commands are account-scoped (--owner / --project-id, project token scope).

Previously onboard_service re-enabled the Keycloak client on the build-success path, before the caller ran compute_and_apply (the PCE). A PCE failure then left the client enabled with no applied policy. Move the re-enable out of the orchestrator into a new UC1-only, idempotent reenable_service(service_id) that the caller invokes AFTER a successful compute_and_apply — in the Controller /apply/service route and, for the service-onboarding subject only, in the NATS consumer. The rollback-on-failure disable path is unchanged. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>
Guard the full onboard_service provision->build->rollback lifecycle with a per-service_id threading.Lock (lazily created under a module-level guard lock). Same-service runs now run one at a time so a concurrent run cannot corrupt the created-manifest or roll back a shared entity; different service_ids stay concurrent. reenable_service stays outside the lock. In-process lock only (single replica); cross-replica coordination is out of scope. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Oleg Blinder <oblinder@gmail.com>

Good PR. Coderabbit comments addressed. Please wait for clawgenti review results as well.
Problem
During service onboarding (UC1), a failure in the policy build step (
provision → ServicePolicyBuilder.build) left partial state behind: roles/scopes created by Provision were not undone, the Keycloak client stayed enabled with no failure marker, LLM failures escaped as untyped500s, and the NATS path treated every error the same (blind redelivery). Policy authors also saw contradictions one at a time instead of all at once.Solution
Implements a six-part error-handling & teardown effort across three layers:
Consumer layer (AIAC Agent / UC1)
ServicePolicyBuilder.build: accumulate-and-merge — catchPolicyContradictionErrorper PRB call, continue the fan-out, then union withdetect_conflictsinto oneConflictReport(all conflicts at once); hard failures short-circuit.client.type, and disable the client (enabled=false) as a visible failed-service marker; success path re-enables (idempotent).
