Note

Introduces a comprehensive Unified Logger epic with interfaces and requirements, adds an Interfaces section and constraints to the epic template, and updates plan.md entries.

Planning/Docs:
- New Epic: Add tasks/unified-logger-epic.md defining a unified client/server logging framework.
  - Includes SudoLang interface types, logger options/return types, storage adapter, and event schemas.
  - Outlines requirements for core infrastructure, client/server implementations, event config, security/privacy, client transport, server endpoint, schema validation, testing, and documentation.
- Epic Template Update (ai/rules/task-creator.mdc):
  - Add dedicated Interfaces section with SudoLang examples.
  - Extend constraints to prioritize interfaces and align requirements; add review checklist items for interfaces alignment.
- Plan Update (plan.md):
  - Fix formatting for Context7 GitHub Action epic entries.

+**Requirements**:
+- Given browser is online, should flush batched events immediately in background
+- Given browser is offline, should buffer events to localStorage without data loss
+- Given browser reconnects after offline period, should auto-flush pooled buffers


Corrected spelling of 'pooled' to 'pooled' (likely meant 'queued').

Suggested change

- Given browser reconnects after offline period, should auto-flush pooled buffers

- Given browser reconnects after offline period, should auto-flush queued buffers

Updated requirements and refined logging behavior for both client and server. Modified event handling and transport logic, including consent checks and error handling.

+- Given client online and flushIntervalMs elapsed, should flush on timer
+- Given POST to /api/events/[id] fails, should log error to console and ignore (fire-and-forget)
+- Given batch to flush, should POST to /api/events/[eventId] with Content-Type application/json
+- Given multiple events to flush, should batch into single POST body with events array


Bug: Batching Conflicts with URL Design

The client transport requirements for flushing events are contradictory. The design specifies POSTing to an endpoint with a single event ID in the URL path, but also requires batching multiple events into a single request body. This creates an ambiguous URL structure for batched requests and conflicts with the server's idempotency handling, which expects individual event IDs.

tasks/unified-logger-epic.md

+- Given request method is not POST, should reject with 405 Method Not Allowed
+- Given Content-Type is not application/json, should reject with 415 Unsupported Media Type
+- Given request origin not in allowedOrigins, should reject with 403 Forbidden
+- Given request referer origin does not match origin header, should reject with 400 Bad Request


The requirement mentions checking "referer origin" but the correct HTTP header name is "Referer" (note the misspelling in the HTTP standard is intentional). However, the requirement says "request referer origin does not match origin header" which seems like a security check. Consider clarifying what this check is validating - typically you'd check that the Origin header matches allowed origins, or that Referer matches the request origin, but checking "referer origin does not match origin header" is unclear. This might need to be: "Given request Referer header origin does not match Origin header, should reject with 400 Bad Request" or simply removed if covered by the allowedOrigins check on line 219.

Suggested change

- Given request referer origin does not match origin header, should reject with 400 Bad Request

+// Configuration
+LoggerOptions {
+  endpoint?: string           // POST target (client: '/api/events', server: 'console')


Inconsistent endpoint definition. Line 58 defines the client endpoint as '/api/events' but the Client Transport Layer (line 201, 207) and Server Event Endpoint (line 214) sections describe the endpoint as /api/events/[id] or /api/events/[eventId]. The endpoint should be consistently defined. Based on the idempotent delivery design mentioned in line 201, the endpoint in LoggerOptions should likely be '/api/events' as a base, with the implementation appending /${eventId} when making requests.

Suggested change

endpoint?: string // POST target (client: '/api/events', server: 'console')

endpoint?: string // POST base path (e.g., '/api/events'); implementation appends '/${eventId}' for idempotent delivery (client), or 'console' for server

+**Status**: 📋 PLANNED
+**File**: [`tasks/unified-logger-epic.md`](./tasks/unified-logger-epic.md)
+**Goal**: Create event-driven logging framework for unified telemetry across client and server
+**Tasks**: 9 tasks (core infrastructure, client implementation, server implementation, event configuration, security/privacy, transport, schema validation, testing, documentation)


Incorrect task count and incomplete task list. The summary states "9 tasks" but the epic contains 10 task sections. Additionally, the task list omits "Server Event Endpoint" (which is distinct from the Client Transport Layer). Update to: "10 tasks (core infrastructure, client implementation, server implementation, event configuration, security/privacy, client transport, server endpoint, schema validation, testing, documentation)".

Suggested change

**Tasks**: 9 tasks (core infrastructure, client implementation, server implementation, event configuration, security/privacy, transport, schema validation, testing, documentation)

Inconsistent capitalization of "RxJS". The library name "RxJS" should be consistently capitalized. Line 83 uses lowercase "rxjs pipeable operator" and line 249 uses lowercase "rxjs". These should be "RxJS pipeable operator" and "RxJS" respectively to match the official library name capitalization used in the type name "RxJSOperator".

Suggested change

Inconsistent capitalization of "RxJS". The library name should be "RxJS" (not "rxjs") to match the official library name capitalization used elsewhere in the document (e.g., "RxJSOperator" type name).

Missing interface definition. The Server Event Endpoint requirement (line 219) references allowedOrigins for origin validation, but this configuration option is not defined in the LoggerOptions interface. Add allowedOrigins?: string[] to the LoggerOptions interface to align with this requirement, or clarify how allowed origins are configured.

+  level?: LogLevel               // default: 'info'


Missing interface definition. The Schema Validation requirement (line 238) mentions that developers can "register EventConfig with schema", but the EventConfig interface (lines 81-87) does not include a schema field. Add schema?: object or a more specific JSON schema type to the EventConfig interface to align with this requirement.

Suggested change
