docs(10.2-03): complete plan — scope reduction due to n8n static data limitation

Browse Source 
- Created 10.2-03-SUMMARY.md documenting scope reduction and platform limitation
- Updated STATE.md: Phase 10.2 complete (3/3 plans)
- Documented critical finding: n8n static data does not persist between executions
- Final state: 170 nodes (168 baseline + 2 correlation ID generators)
- Correlation ID infrastructure and structured error returns retained

| 10.1-08 | HTTP 304 treated as success | Docker API returns 304 for already-in-state, better UX than error |
| 10.1-09 | /list command as alias for status | Status command already provides list functionality; alias simpler than duplication |
| 10.1-09 | Dynamic predecessor reference pattern | Use $input.item.json for nodes with multiple incoming paths |
- [Phase 10.2-01]: Ring buffer size set to 50 entries for both errors and traces
- [Phase 10.2-01]: Debug mode auto-disables after 100 executions to prevent performance impact
- [Phase 10.2-01]: All 4 debug commands use single unified code node for maintainability
- [Phase 10.2-03]: n8n workflow static data does NOT persist between executions (critical platform limitation)
- [Phase 10.2-03]: Ring buffer + debug commands architecture non-functional due to static data limitation
- [Phase 10.2-03]: Stripped all static-data-dependent features, kept correlation IDs + structured error returns
- [Phase 10.2-02]: Correlation ID uses timestamp + random string (no UUID dependency)
- [Phase 10.2-02]: Use $input.item.json.correlationId pattern for Prepare Input nodes
- [Phase 10.2-02]: Added error detection for 2 high-value paths (reduced from 6 to minimize nodes)
- [Phase 10.2-03]: Final state 170 nodes (168 baseline + 2 correlation generators)

| 10.2-02 | Wire Error Logging to Main Workflow | Complete (error logging removed, correlation IDs kept) |
| 10.2-03 | Add Debug Tracing to Sub-workflow Boundaries | Complete (scope reduced due to static data limitation) |
**Achievements (10.2-01):**
- Ring buffer infrastructure in workflow static data (max 50 errors, 50 traces)
- 4 hidden debug commands: /errors, /clear-errors, /debug, /trace
- Process Debug Command unified handler node with HTML formatting
- Log Error utility node with field truncation and pass-through
- Log Trace utility node with debug mode toggle and auto-disable
- Main workflow: 168 -> 172 nodes (+4 nodes)
**Critical Finding:**
- **n8n workflow static data does NOT persist between executions** (execution-scoped, not workflow-scoped)
- Ring buffer + debug command architecture non-functional due to this limitation
- All static-data-dependent features stripped in Plan 03 cleanup
**Achievements (10.2-02):**
- Structured error returns added to all 7 sub-workflows (success/error fields)
- Correlation ID generation for text and callback paths (timestamp + random)
- 19 Prepare Input nodes modified to pass correlationId to sub-workflows
- 2 error detection IF nodes for Container Action and Inline Action paths
- Error objects include workflow, node, message, httpCode, rawResponse
- Main workflow: 172 -> 176 nodes (+4 nodes)
**Achievements (10.2-01):** [REMOVED in 10.2-03 cleanup]
- Ring buffer infrastructure (non-functional - static data doesn't persist)
- 4 hidden debug commands (removed)
- Log Error and Log Trace utility nodes (removed)
**Achievements (10.2-02):** [PARTIALLY RETAINED]
- Structured error returns in all 7 sub-workflows (KEPT - success/error fields)
- Correlation ID generation for text and callback paths (KEPT - 2 nodes)
- 19 Prepare Input nodes modified to pass correlationId (KEPT)
- Error detection IF nodes (REMOVED - depended on static data logging)
**Final State (10.2-03):**
- Main workflow: 170 nodes (168 baseline + 2 correlation ID generators)
- Correlation ID infrastructure functional (traces requests through n8n execution logs)
- Structured error returns in all sub-workflows (enables better error handling)
- All static-data-dependent features removed cleanly
- No regression to bot functionality
## Next Step
Phase 10.2 in progress. Plans 01-02 complete (ring buffer foundation, error propagation). Next: Plan 03 (add debug tracing to sub-workflow boundaries).
Phase 10.2 complete (3/3 plans). Critical finding: n8n static data does not persist between executions. Correlation ID infrastructure and structured error returns retained. Ready for Phase 11 (Update All & Callback Limits).
