- `n8n-batch-ui.json` -- Batch UI sub-workflow (17 nodes: 16 baseline + 1 Fetch Containers For Exec) -- ID: `ZJhnGzJT26UUmW45`
- `n8n-status.json` -- Container Status sub-workflow (11 nodes) -- ID: `lqpg2CqesnKE2RJQ`
- `n8n-confirmation.json` -- Confirmation Dialogs sub-workflow (16 nodes) -- ID: `fZ1hu8eiovkCk08G`
- `n8n-update.json` -- Container Update sub-workflow (34 nodes) -- ID: `7AvTzLtKXM2hZTio92_mC`
- `n8n-actions.json` -- Container Actions sub-workflow (11 nodes) -- ID: `fYSZS5PkH0VSEaT5`
- `n8n-logs.json` -- Container Logs sub-workflow (9 nodes) -- ID: `oE7aO2GhbksXDEIw`
- `n8n-matching.json` -- Container Matching sub-workflow (23 nodes) -- ID: `kL4BoI8ITSP9Oxek`
- `DEPLOY-SUBWORKFLOWS.md` -- Full architecture docs, contracts, and node analysis

## Technical Notes

**n8n typeVersion 1.2 requirement:**
```json
"workflowId": { "__rl": true, "mode": "list", "value": "<id>" }
```

**Docker API success detection:**
- 204 No Content = success (empty response body)
- Check `!response.message && !response.error`

**Sub-workflow input contracts:**
- Container Update: containerId, containerName, chatId, messageId, responseMode
- Container Actions: containerId, containerName, action, chatId, messageId, responseMode
- Container Logs: containerId/containerName, lineCount, chatId, messageId, responseMode
- Batch UI: chatId, messageId, queryId, callbackData, action, batchPage, selectedCsv, toggleName, batchAction
- Container Status: chatId, messageId, action, containerId, containerName, page, queryId, searchTerm
- Confirmation: chatId, messageId, action, containerId, containerName, confirmAction, confirmationToken, expired, responseMode
- Matching: action, containerList, searchTerm, selectedContainers, chatId, messageId

**Sub-workflow output patterns:**
- Batch UI returns `action` field (keyboard/execute/cancel)
- Container Status returns `action` field (list/status/paginate)
- Confirmation returns `action` field (show_stop/show_update/confirm_stop_result/confirm_update/cancel/expired)
- Matching returns `action` field (matched/multiple/no_match/error/suggestion/batch_matched/disambiguation/not_found + update variants)
- Main workflow routes based on action to appropriate Telegram response handler

**Data chain pattern (10-07):**
- Use `$('Build Progress Message').item.json` to reference data across async nodes
- Do not rely on `$json` after Telegram API calls (response overwrites data)

**Dynamic input pattern (10-09):**
- Use `$input.item.json` for nodes with multiple predecessors
- Matching sub-workflow returns both `action` (routing label) and `actionType` (user's requested action)

## Accumulated Decisions

| Phase | Decision | Rationale |
|-------|----------|-----------|
| 10-05 | Use placeholder workflow ID for logs sub-workflow | ID assigned by n8n on import |
| 10-05 | Retain Parse Logs Command in main workflow | Handles error cases before sub-workflow call |
| 10-06 | Remove old batch inline path | Migrated to bexec: callback format, uses sub-workflow |
| 10-06 | Defer aggressive modularization to 10.1 | Core goals achieved, deeper work needs separate phase |
| 10-07 | Timestamp on logs refresh | Prevents "message not modified" error, shows freshness |
| 10-07 | Fuzzy matching in logs sub-workflow | Simpler than duplicating Docker query infrastructure |
| 10.1-01 | Realistic target 115-125 nodes (not 50-80) | 58 Telegram response nodes locked to main workflow |
| 10.1-01 | Wave 2: Batch UI + Container List extraction | Highest-value domains with clear boundaries |
| 10.1-02 | Partial batch UI extraction (UI only, not loop) | Batch execution loop cannot be in sub-workflow due to n8n limitations |
| 10.1-02 | Action-based sub-workflow routing | Sub-workflow returns action field, main routes to Telegram handlers |
| 10.1-03 | Minimal net node reduction due to integration overhead | Removed 10 nodes but added 9 integration nodes; value is complexity reduction |
| 10.1-04 | Return confirm_update action to main workflow | Update flow tightly integrated with existing update sub-workflow |
| 10.1-04 | Call n8n-actions.json for stop execution | Reuse existing action execution instead of duplicating Docker API calls |
| 10.1-06 | Downstream nodes reference original parse nodes for action type | Sub-workflow doesn't carry user's requested action (stop/start) through return data |
| 10.1-06 | Text-mode status needs keyboard strip + messageId routing | Pre-existing bug exposed by testing; text commands have no message to edit |
| 10.1-06 | Batch text needs Prepare Batch Execution transform | Sub-workflow returns matchedContainers/batch_matched, downstream expects allMatched/stop |
| 10.1-07 | No further Code node extraction viable | 2 candidates yield net-negative extraction (-50% efficiency) |
| 10.1-07 | 168 nodes is near-minimal (structural minimum: 166) | Evidence-based analysis of all 168 nodes by category |
| 10.1-07 | 115-125 target was unrealistic | Based on incomplete extraction overhead analysis |
| 10.1-08 | Status code checks before message-based fallback | Explicit HTTP response handling before message parsing |
| 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 10.2-03]: 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 10.2-04]: Fixed connection keys to use node names per n8n resolution protocol
- [Phase 10.2-04]: Accepted debug/errors routing behavior as minor (commands removed, no real users)
- [Phase 10.2-04]: Final state 168 nodes (includes 2 correlation ID generators, 2 orphans removed)
- [Phase 10.2-04]: Fixed connection keys to use node names per n8n resolution protocol
- [Phase 10.2-04]: Accepted debug/errors routing behavior as minor (commands removed, no real users)
- [Phase 11-01]: Use base36 BigInt encoding for bitmaps (supports 50+ containers, max ~20 bytes callback size)
- [Phase 11-01]: Retain old batch parsers for graceful migration of in-flight messages (<1 minute window)
- [Quick 1-1]: Removed 6 orphan callback nodes (no incoming connections after Phase 10 modularization)
- [Quick 1-1]: Achieved structural minimum of 166 nodes (per Phase 10.1-07 analysis)

## Phase 10.1 Progress

| 10.1-09 | UAT Gap Closure: Data Flow Fixes | Complete |

**Node count progress:**
- Start: 192 nodes
- After 10.1-02: 179 nodes (-13)
- After 10.1-03: 178 nodes (-1)
- After 10.1-04: 168 nodes (-10)

- Confirmation: -10 nodes (16 nodes in sub-workflow)
- Matching: net 0 (23 nodes in sub-workflow, complexity reduction)
- Total reduction: 24 nodes (192 -> 168, -12.5%)

## Phase 10.1 Sub-workflows

All 7 sub-workflows deployed and operational:
- n8n-update.json -- `7AvTzLtKXM2hZTio92_mC`
- n8n-actions.json -- `fYSZS5PkH0VSEaT5`
- n8n-logs.json -- `oE7aO2GhbksXDEIw`
- n8n-batch-ui.json -- `ZJhnGzJT26UUmW45`
- n8n-status.json -- `lqpg2CqesnKE2RJQ`
- n8n-confirmation.json -- `fZ1hu8eiovkCk08G`
- n8n-matching.json -- `kL4BoI8ITSP9Oxek`

## Phase 10.2 Progress

| Plan | Description | Status |
|------|-------------|--------|
| 10.2-01 | Error Ring Buffer Foundation and Hidden Debug Commands | Complete (infrastructure later removed) |
| 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) |
| 10.2-04 | Gap Closure: Correlation ID Wiring | Complete (UAT gaps 1-3 closed) |

**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 (10.2-01):** [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 (10.2-04):**
- Main workflow: 168 nodes (includes 2 correlation ID generators, 2 orphans removed)
- Correlation ID infrastructure wired and functional (text + callback paths)
- Correlation IDs flow to all sub-workflows via Prepare Input nodes
- Structured error returns in all sub-workflows (enables better error handling)
- All static-data-dependent features removed cleanly
- UAT gaps 1-3 closed (correlation ID wiring), gap 4 accepted as minor
- No regression to bot functionality

## Phase 11 Progress

| Plan | Description | Status |
|------|-------------|--------|
| 11-01 | Bitmap encoding for batch selection | Complete |
| 11-02 | Update All button with confirmation | Pending |

**Achievements (11-01):**
- Bitmap-encoded batch selection eliminates 64-byte Telegram callback limit
- Supports unlimited container selection (max ~20 bytes for 50+ containers)
- Base36 BigInt encoding: `b:0:1a3:5` vs old CSV `batch:toggle:0:plex,sonarr:jellyfin`
- Graceful migration: old parsers retained as fallback for in-flight messages
- Batch stop confirmation works with bitmap via resolution flow
- n8n-batch-ui.json: 17 nodes (16 + 1 Fetch Containers For Exec)
- n8n-workflow.json: 166 nodes (structural minimum achieved)
