Summary by CodeRabbit
Documentation
Updated the Cedarling component diagram and descriptions to clarify the roles of its interfaces, policy and context services, Cedar Engine, and observability.
Clarified policy-store sources, signature verification and refresh; token signature and claim validation and revocation checks; and optional time-to-live settings for pushed context data.
Documented TRACE-signed decision evidence and the optional Lock Server’s role in centrally storing logs, telemetry, and evidence, as well as providing the policy store in enterprise deployments.

The Cedarling README replaces its component diagram and descriptions. A new Python script defines the diagram, renders it as SVG, and can use headless Chrome or Chromium to create a PNG.

Summary
Diagram rendering and documentation jans-cedarling/scripts/render_components_diagram.py, docs/cedarling/README.md
The README describes the updated Cedarling components and connections. The script defines the diagram and renders it as SVG.
PNG capture and command-line options jans-cedarling/scripts/render_components_diagram.py
The script accepts PNG output, optional SVG output, and a scale. It locates Chrome or Chromium, captures a PNG, and reports browser errors or timeouts.

Explanation
The title "docs(jans-cedarling): redraw outdated Cedarling components diagram" matches the main change. The PR replaces the outdated components diagram and its descriptions, and adds a script that renders the diagram. It follows the docs: commit convention and is concise and specific.
Full details: Description check
Explanation
The description follows the repository template and fills in the target issue (closes #15531) and the documentation checkbox, which is checked. It leaves the Implementation Details section empty, although the template's comment suggests adding a high-level approach for involved fixes. The static analysis and unit/integration test checkboxes are unchecked, and the docs-impact checkbox is unchecked. Those unchecked items are not clearly required for a documentation-only change, but the author should confirm them. The PR does add a Python script, and no tests are mentioned for it.
Full details: Docstring Coverage
Explanation
Docstring coverage is 12.50% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 8 functions across 1 files.
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.
Full details: Linked Issues check
Explanation
The available evidence supports part of #15531. It shows the new Python renderer and the updated Cedarling Components section. The generated PNG is excluded from review, and the evidence does not independently confirm its contents or confirm removal of the obsolete JPG. The exact diagram flows therefore cannot be fully assessed.
Resolution
Provide reviewable evidence for the generated docs/assets/cedarling/cedarling-components.png, including the required components and data flows, and for removal of docs/assets/cedarling/lock-cedarling-rust-core-components.jpg.

⚠️Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Add a timeout and surface Chrome failures.
subprocess.run has no timeout. A hung headless Chrome process blocks the script forever. The call also sends stderr to DEVNULL, so a failure gives only a bare exit code.
Chrome does not create parent directories. If --output points to a missing directory, the screenshot fails and the script gives no reason. The script does not check that the PNG exists after the run.
Apply these changes:
Add a timeout and handle subprocess.TimeoutExpired.
Capture stderr and print it on a non-zero exit code.
Create the output directory with os.makedirs(os.path.dirname(os.path.abspath(output)), exist_ok=True) before the call.
Return a failure code if the output file is missing after a zero exit code.
The command is a list and does not use shell=True. CHROME comes from the invoking user's environment. The ast-grep command-injection hints are therefore not a vulnerability.
🛠️ Proposed fix
- return subprocess.run(command, stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL).returncode+ try:+ result = subprocess.run(+ command, stdout=subprocess.DEVNULL, stderr=subprocess.PIPE,+ text=True, timeout=120, check=False,+ )+ except subprocess.TimeoutExpired:+ print("Chrome timed out while rendering the diagram", file=sys.stderr)+ return 1+ if result.returncode != 0:+ print(result.stderr, file=sys.stderr)+ return result.returncode

Link the interfaces reference instead of pointing at text above that does
not cover metrics or policy annotations. Bound the Chrome run with a
timeout and print its stderr on failure, so a broken browser does not
hang the script or fail silently.

alongside logs and telemetry.

The decision edge ends at Observability. The diagram therefore does not show the Cedar Engine returning the allow/deny result to Authorize, although the README documents that return.
Keep the existing observability edge and add a routed edge to the Authorize node:

Reverse the inspection edges so data flows from Observability and Policy Store Manager to Inspect & Observe.
The Inspect & Observe edges point the wrong way. Per the README, the interface reads logs, metrics, and policy annotations from Cedarling components. Both edges instead send an arrow from the interface to the component:
Line 102 draws an arrowhead into Observability at its left edge (380, 658).
Line 107 draws a dotted policy annotations arrowhead into Policy Store Manager at its top edge (560, 140).
Swap the point order of both edges. The final point carries the arrowhead, so the arrow then points at Inspect & Observe. Regenerate docs/assets/cedarling/cedarling-components.png after the edit.

⚠️Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Make the SVG string construction explicit.
Ruff reports ISC004 because adjacent f-strings are implicitly concatenated inside the parts list. Assign the concatenated value in parentheses before adding it to the list. This preserves the SVG output and removes the ambiguous collection syntax. (raw.githubusercontent.com)

Manager to the interface, since it reads logs, metrics and annotations

undecodable output cannot raise after a successful screenshot.
