Summary by CodeRabbit

  • Breaking Changes

    • Legacy JSON policy stores are no longer supported and now return migration guidance.
    • Policy store URLs require .cjar archives; local sources support directories and .cjar archives, with YAML retained for test suites.
    • Inline policy configuration supports YAML strings and structured documents; blank values are rejected.
  • Documentation

    • Updated Cedarling, Java, Go, Python, JavaScript, WASM, and UniFFI examples for supported formats.
    • Clarified policy-store requirements and migration guidance.
  • Tests

    • Added coverage for rejecting legacy JSON configurations.
    • Updated scenarios and fixtures for YAML and Cedar Archive formats.

📝 Walkthrough

Walkthrough

Cedarling removes legacy JSON policy-store loading and conversion. Configuration, URI refresh, bindings, fixtures, tests, and documentation now use CJAR archives, directories, or YAML test fixtures.

Changes

Policy-store contracts and loading

Layer / File(s) Summary
Policy-store source contracts and configuration
jans-cedarling/cedarling/src/bootstrap_config/..., jans-cedarling/cedarling-cli/src/..., jans-cedarling/cedarling/config/default_config.yaml
JSON source variants were removed. JSON configuration now returns LegacyJsonNotSupported. Supported sources are YAML, CJAR, directories, and archive URLs.
Archive-only loading and refresh
jans-cedarling/cedarling/src/init/..., jans-cedarling/cedarling/src/lib.rs
URI and Lock Server loading no longer parses JSON responses. Refresh paths accept CJAR ZIP archives and reject legacy JSON.
Validation tests and YAML fixtures
jans-cedarling/cedarling/src/tests/..., jans-cedarling/test_files/..., jans-cedarling/bindings/cedarling_python/tests/...
Validation tests use YAML directly. Error fixtures were migrated to YAML, and retained JSON fixtures cover rejection cases.

Binding migrations

Layer / File(s) Summary
Binding inputs and test resources
jans-cedarling/bindings/cedarling_js/..., jans-cedarling/bindings/cedarling_python/..., jans-cedarling/bindings/cedarling_uniffi/..., jans-cedarling/bindings/cedarling_wasm/...
Bindings accept raw YAML strings, CJAR archive bytes, or YAML resources. Examples and fixtures no longer depend on legacy JSON policy stores.

Documentation

Layer / File(s) Summary
Documentation and examples
docs/cedarling/..., jans-cedarling/bindings/*/README.md
Examples now use CJAR archives or folder-based stores. Documentation identifies YAML as the remaining single-file format for test suites and removes legacy JSON guidance.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 2ae8b

Legacy JSON policy stores may still be accepted through YAML-prefixed input or fail unexpectedly for JavaScript callers passing object policy stores, undermining the format-removal change. Documentation and formatting inconsistencies remain, while archive-byte initialization now handles configured CJAR URLs correctly.

50-60: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Reject object inline documents or serialize them as YAML.

At Line 59, JSON.stringify(snapshot) writes legacy JSON into CEDARLING_POLICY_STORE_LOCAL. The core loader now rejects inline JSON with LegacyJsonNotSupported. Any JavaScript caller that supplies { type: "inline", document: {} } passes this validation and then fails during initialization.

Remove JsonObject support from the public and prepared source types, and reject non-string documents here. Alternatively, convert object input to valid YAML before setting the bootstrap property.

Proposed direction
-      readonly document: JsonObject | string;
+      readonly document: string;
-      let snapshot: JsonObject;
-      try {
-        snapshot = snapshotJsonObject(document, "initialize");
-      } catch {
+      if (typeof document !== "string") {
         return invalid(errorCode.inputInvalidType, [
           "policyStore",
           "document",
         ]);
       }
-      bootstrap.CEDARLING_POLICY_STORE_LOCAL = JSON.stringify(snapshot);
-      return { type, document: snapshot };
+      bootstrap.CEDARLING_POLICY_STORE_LOCAL = document;
+      return { type, document };

Inline comments:
In `@docs/cedarling/quick-start/cedarling-quick-start.md`:
- Line 128: Update the Cedarling quick-start guidance for
CEDARLING_POLICY_STORE_URI to state that the endpoint must return a valid
.cjar/ZIP archive and that raw directory URLs are unsupported; remove the
requirement that the URL itself use a .cjar suffix.

In `@docs/cedarling/reference/cedarling-properties.md`:
- Line 39: Update the CEDARLING_POLICY_STORE_LOCAL documentation to describe
supported non-empty inline YAML values mapped by build_policy_store_config to
PolicyStoreSource::Yaml, rather than stating the property always fails; also
list this property among local sources excluded from refresh.

In `@docs/cedarling/tutorials/javascript.md`:
- Line 116: Update the archive-loading example around init_from_archive_bytes to
call and await initWasm() before invoking any exported binding function,
preserving the existing archive-loading flow.

In `@jans-cedarling/bindings/cedarling_uniffi/README.md`:
- Line 312: Update the load_from_json documentation to include
CEDARLING_POLICY_STORE_LOCAL as a valid inline YAML policy-store source, noting
that the WASM binding uses it directly and inline JSON is rejected.

In `@jans-cedarling/bindings/cedarling-java/README.md`:
- Around line 177-178: Update the configuration example to show
CEDARLING_POLICY_STORE_LOCAL_FN and CEDARLING_POLICY_STORE_URI as separate,
mutually exclusive alternatives rather than setting both together; preserve the
existing local and remote values.

In `@jans-cedarling/cedarling/src/bootstrap_config/decode.rs`:
- Around line 142-143: Update build_policy_store_config to detect and reject
legacy JSON after leading YAML comments or document prefixes, before
deserializing LegacyAgamaPolicyStore; define the format boundary explicitly,
including whether JSON-like flow mappings remain supported. Add regression tests
covering prefixed/commented legacy JSON and the chosen flow-style YAML behavior.

In `@jans-cedarling/cedarling/src/bootstrap_config/policy_store_config.rs`:
- Line 154: Wrap the overlong match arm in the policy-store configuration
decoding logic so it complies with the 100-character limit, while preserving the
existing LegacyJsonNotSupported error behavior and formatting style.

In `@jans-cedarling/cedarling/src/init/policy_store.rs`:
- Line 25: Reformat the long legacy policy store error message near the
initialization error definition so every source line is at most 100 characters,
while preserving the complete existing error text and behavior.
- Around line 244-245: Update the legacy JSON detection around the policy-store
loading logic to skip leading JSON whitespace before checking for `{`,
preserving the LegacyJsonNotSupported error for whitespace-prefixed JSON. Apply
the same detection in policy_store.rs lines 244-245 and policy_store_refresh.rs
lines 381-382; both sites require the direct change.
- Around line 149-152: Update the YAML policy-loading path around
serde_yaml_ng::from_str and the corresponding PolicyStoreSource::FileYaml
handling to detect input whose first non-whitespace content is JSON before YAML
parsing, returning LegacyJsonNotSupported instead of processing it as a legacy
store. Add regression coverage for both inline PolicyStoreSource::Yaml and
file-based JSON inputs.

Convert object-valued inline policy sources to supported YAML.

prepare.ts sends policyStore to policy-source.ts, where JsonObject input becomes JSON text in CEDARLING_POLICY_STORE_LOCAL. Cedarling’s PolicyStoreSource::Yaml path rejects that content with LegacyJsonNotSupported, so current object-based configurations fail during initialization. Convert objects to supported YAML, or reject them at runtime and remove JsonObject from the public contract.

Can we simplify this function to:

Suggested change
/// Checks whether text content represents a JSON document (object or array)

I think we can avoid mapping bytes to string just to check if it's start looks like json

- Line 447: Update is_json_bytes to skip YAML document markers and comment-only
prologue lines before classifying the first document token, so JSON objects or
arrays following a prologue are still recognized as legacy JSON. Add a negative
regression test covering `--- # comment\n{"cedar_version":"v4.0.0"}` and
