Pre-fix, every caller of `PolicyEngine::load(path, graph_id)` passed *some* `graph_id` argument — even when the policy was server-scoped and Cedar's resolution would never touch a Graph entity. The server-level loader at lib.rs passed the meaningless sentinel `"server"`. A graph policy file containing a `graph_list` rule compiled fine; a server policy file containing a `read` rule compiled fine. Both silently no-op'd at request time because the engine kind and the rule's resource kind disagreed. Correct-by-design fix: replace `load` with two kind-typed loaders. * `PolicyEngine::load_graph(path, graph_id)` — for per-graph policy files. Rejects any rule whose action `resource_kind()` is `Server`. * `PolicyEngine::load_server(path)` — for server-level policy files. Takes no `graph_id`: server-scoped actions resolve against the singleton `Omnigraph::Server::"root"` entity, never a Graph. Rejects any rule whose action `resource_kind()` is `Graph`. The old `load` is hard-deleted in the same commit because every in-tree consumer migrates here (no semver promise on the workspace crate, no external pinners). New `PolicyEngineKind` enum types the loader's intent; `validate_kind_alignment` is the load-time check that closes the "wrong action, wrong file, silent no-op" class — operators get a load-time error instead of confused-and- silent behavior at request time. Callsites migrated: * server lib.rs:374 (single-mode per-graph) → load_graph * server lib.rs:1065 (multi-mode server) → load_server * server lib.rs:1103 (multi-mode per-graph) → load_graph * CLI main.rs:732 (resolve_policy_engine) → load_graph * tests/server.rs ×5 (4 graph, 1 server) → load_graph/load_server * policy_engine_chassis.rs → load_graph Four new in-source tests pin the contract: both rejection paths and both positive paths. Closes the "operator puts an action in the wrong file and the rule silently never matches" class. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
