Verified Service-Wide Defaults: The initial integration test run confirmed that the service-wide default attribution was working as expected. Implemented Per-Node Attribution: The meshes route at flow-service/src/routes/meshes.ts was updated to load node-specific configurations. The logic now correctly prioritizes the conf:attributedTo property from the node's flow-config.jsonld file. Corrected Configuration Path: The getNodeConfigPath() function in flow-core/src/mesh-constants.ts was updated to point to the correct configuration file path. Added Integration Test: A new test case was added to flow-service/tests/integration/meshes-routes.integration.test.ts to specifically test and validate the per-node attribution override. Verified Fallback Behavior: The existing tests also confirm that the system correctly falls back to the service-wide default attribution when a node-specific configuration is not present.
Examine configuration files for default provenance data Examine the integration test for root node creation Check if the API endpoint implementation is missing Verify the current API endpoint generates metadata correctly Test the endpoint functionality to ensure it works as expected Fix hardcoded attribution - add fsvc:defaultAttributedTo configuration Update meshes endpoint to use configurable attribution Update configuration types and tests Locate or create config-flow ontology for per-node attribution Add conf:attributedTo property to config-flow ontology Implement per-node attribution configuration support in API Update node configuration types and loading Test per-node attribution functionality Fix mesh discovery issue - meshes aren't being initialized from config Improve error handling - return 404 Not Found instead of 500 Internal Server Error Test the complete mesh discovery and node creation workflow Fix error response format to return proper JSON instead of plain text

""" WalkthroughThis update introduces mesh management API endpoints to the flow-service, including routes for registering meshes and creating nodes within them. New configuration options for attribution and delegation are added, with corresponding type definitions and accessors. Integration and unit tests are provided for the new mesh routes. Several configuration and guidance files are updated or expanded. Changes

.clinerules/cline-guidance.md (1)
1-1: Clarify & structure the instruction for easier complianceThe single-sentence note is easy to overlook and mixes several actions. Consider converting it into a concise, bulleted checklist and code-formatting the referenced paths. Example patch:
-On every new task, read the .ai-guidance.md file in the workspace root. It mentions two other guidance files and a bunch of ontology files. Make sure those are in the context when you start the task. +On every new task, first read the file `.ai-guidance.md` at the workspace root. +That file references: +1. `sflo-dendron-notes/sflo.contributors.general-guidance.md` +2. `sflo-dendron-notes/sflo.contributors.djradon.ai-guidance.md` +3. All ontologies under the `ontology/` folder + +Ensure the content of these resources is loaded into your context before you begin work..ai-guidance.md (2)
5-5: Grammar & formatting tweak for smoother readingDrop the extra comma and put the path in back-ticks to distinguish it from prose:
-General guidance for all contributors, including synthetic ones, can be found in sflo-dendron-notes/sflo.contributors.general-guidance.md. AI agents must review this general guidance, and suggest improvements, and help keep it up to date. +General guidance for all contributors, including synthetic ones, can be found in `sflo-dendron-notes/sflo.contributors.general-guidance.md`. +AI agents must review this document, suggest improvements, and help keep it up to date.
11-14: Make ontology expectations actionableThe current paragraph tells agents to “keep those ontologies in your context” but doesn’t say how or what to do when they evolve. A short actionable list tightens the guidance:
-There are several ontologies in the "ontology" folder (which is actually its own repo). Keep those ontologies in your context at all times. +The repository maintains multiple domain ontologies under the `ontology/` folder (hosted as a sub-module). +• Ensure these ontologies are loaded into your context at task start. +• When adding or modifying concepts, cross-check against existing ontologies. +• Raise a follow-up PR if an ontology update is required.flow-service/src/routes/health.ts (1)
4-4: Remove unused import.The
Contextimport from'jsr:@hono/hono'is not used anywhere in this file and should be removed to keep imports clean.-import { Context } from 'jsr:@hono/hono';flow-service/tests/unit/meshes-routes.unit.test.ts (3)
31-31: Simplify the Deno.stat stub for better readability.The stat stub contains many unnecessary properties. Since the production code only checks
isDirectory, you can simplify this significantly.- const DenoStatStub = stub(Deno, "stat", () => Promise.resolve({ isDirectory: true, isFile: false, isSymlink: false, size: 0, mtime: new Date(), atime: new Date(), birthtime: new Date(), dev: 0, ino: 0, mode: 0, nlink: 0, uid: 0, gid: 0, rdev: 0, blksize: 0, blocks: 0, ctime: new Date(), isBlockDevice: false, isCharDevice: false, isFifo: false, isSocket: false })); + const DenoStatStub = stub(Deno, "stat", () => Promise.resolve({ isDirectory: true } as Deno.FileInfo));
48-48: Simplify the Deno.stat stub (same as above).Apply the same simplification as suggested for line 31.
- const DenoStatStub = stub(Deno, "stat", () => Promise.resolve({ isDirectory: true, isFile: false, isSymlink: false, size: 0, mtime: new Date(), atime: new Date(), birthtime: new Date(), dev: 0, ino: 0, mode: 0, nlink: 0, uid: 0, gid: 0, rdev: 0, blksize: 0, blocks: 0, ctime: new Date(), isBlockDevice: false, isCharDevice: false, isFifo: false, isSocket: false })); + const DenoStatStub = stub(Deno, "stat", () => Promise.resolve({ isDirectory: true } as Deno.FileInfo));
46-77: Consider validating the content written to files.The test stubs
Deno.writeTextFilebut doesn't validate what content is being written. Consider capturing and asserting the JSON-LD content to ensure correct metadata structure.You could enhance the test by capturing the written content:
let writtenContent: any; const DenoWriteTextFileStub = stub(Deno, "writeTextFile", (path: string, content: string) => { writtenContent = JSON.parse(content); return Promise.resolve(); }); // After the request, assert the content structure assert(writtenContent['@graph']); assertEquals(writtenContent['@graph'][0]['@type'], 'meta:NodeCreation');flow-service/tests/integration/meshes-routes.integration.test.ts (1)
146-149: Consider adding error handling to teardown.The teardown might fail if the directory doesn't exist or if there are permission issues. Consider wrapping in a try-catch to ensure the test suite doesn't fail during cleanup.
await t.step('teardown: remove test mesh directory', async () => { - await Deno.remove(testMeshPath, { recursive: true }); + try { + await Deno.remove(testMeshPath, { recursive: true }); + } catch (error) { + if (!(error instanceof Deno.errors.NotFound)) { + console.warn(`Failed to clean up test directory: ${error}`); + } + } });flow-service/src/routes/meshes.ts (1)
8-8: Remove commented import.Remove the commented Context import if it's not needed.
-//import { Context } from '@hono/hono';
