-Implement tasks from an OpenSpec change.
-
-**Input**: Optionally specify a change name (e.g., `/opsx:apply add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - Context file paths (varies by schema)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using `/opsx:continue`
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read the files listed in `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-

-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! You can archive this change with `/opsx:archive`.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-Archive a completed change in the experimental workflow.
-
-**Input**: Optionally specify a change name after `/opsx:archive` (e.g., `/opsx:archive add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Prompt user for confirmation to continue
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, execute `/opsx:sync` logic. Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create the archive directory if it doesn't exist:
-   ```bash
-   mkdir -p openspec/changes/archive
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move the change directory to archive
-
-   ```bash
-   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:

-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm

-- Show clear summary of what happened
-- If sync is requested, use /opsx:sync approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-description = "Archive multiple completed changes at once"
-
-prompt = """
-Archive multiple completed changes in a single operation.
-
-This skill allows you to batch-archive changes, handling spec conflicts intelligently by checking the codebase to determine what's actually implemented.
-
-**Input**: None required (prompts for selection)
-
-**Steps**
-
-1. **Get active changes**
-
-   Run `openspec list --json` to get all active changes.
-
-   If no active changes exist, inform user and stop.
-
-2. **Prompt for change selection**
-
-   Use **AskUserQuestion tool** with multi-select to let user choose changes:
-   - Show each change with its schema
-   - Include an option for "All changes"
-   - Allow any number of selections (1+ works, 2+ is the typical use case)
-
-   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
-
-3. **Batch validation - gather status for all selected changes**
-
-   For each selected change, collect:
-
-   a. **Artifact status** - Run `openspec status --change "<name>" --json`
-      - Parse `schemaName` and `artifacts` list
-      - Note which artifacts are `done` vs other states
-
-   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
-      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
-      - If no tasks file exists, note as "No tasks"
-
-   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
-      - List which capability specs exist
-      - For each, extract requirement names (lines matching `### Requirement: <name>`)
-
-4. **Detect spec conflicts**
-
-   Build a map of `capability -> [changes that touch it]`:
-
-   ```
-   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
-   api  -> [change-c]            <- OK (only 1 change)
-   ```
-
-   A conflict exists when 2+ selected changes have delta specs for the same capability.
-
-5. **Resolve conflicts agentically**
-
-   **For each conflict**, investigate the codebase:
-
-   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
-
-   b. **Search the codebase** for implementation evidence:
-      - Look for code implementing requirements from each delta spec
-      - Check for related files, functions, or tests
-
-   c. **Determine resolution**:
-      - If only one change is actually implemented -> sync that one's specs
-      - If both implemented -> apply in chronological order (older first, newer overwrites)
-      - If neither implemented -> skip spec sync, warn user
-
-   d. **Record resolution** for each conflict:
-      - Which change's specs to apply
-      - In what order (if both)
-      - Rationale (what was found in codebase)
-
-6. **Show consolidated status table**
-
-   Display a table summarizing all changes:
-
-   ```
-   | Change               | Artifacts | Tasks | Specs   | Conflicts | Status |
-   |---------------------|-----------|-------|---------|-----------|--------|
-   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
-   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
-   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
-   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
-   ```
-
-   For conflicts, show the resolution:
-   ```
-   * Conflict resolution:
-     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
-   ```
-
-   For incomplete changes, show warnings:
-   ```
-   Warnings:
-   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
-   ```
-
-7. **Confirm batch operation**
-
-   Use **AskUserQuestion tool** with a single confirmation:
-
-   - "Archive N changes?" with options based on status
-   - Options might include:
-     - "Archive all N changes"
-     - "Archive only N ready changes (skip incomplete)"
-     - "Cancel"
-
-   If there are incomplete changes, make clear they'll be archived with warnings.
-
-8. **Execute archive for each confirmed change**
-
-   Process changes in the determined order (respecting conflict resolution):
-
-   a. **Sync specs** if delta specs exist:
-      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
-      - For conflicts, apply in resolved order
-      - Track if sync was done
-
-   b. **Perform the archive**:
-      ```bash
-      mkdir -p openspec/changes/archive
-      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-      ```
-
-   c. **Track outcome** for each change:
-      - Success: archived successfully
-      - Failed: error during archive (record error)
-      - Skipped: user chose not to archive (if applicable)
-
-9. **Display summary**
-
-   Show final results:
-
-   ```
-   ## Bulk Archive Complete
-
-   Archived 3 changes:
-   - schema-management-cli -> archive/2026-01-19-schema-management-cli/

-
-**Conflict Resolution Examples**
-
-Example 1: Only one implemented
-```
-Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
-
-Checking add-oauth:
-- Delta adds "OAuth Provider Integration" requirement
-- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
-
-Checking add-jwt:
-- Delta adds "JWT Token Handling" requirement
-- Searching codebase... no JWT implementation found
-
-Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
-```
-
-Example 2: Both implemented
-```
-Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
-
-Checking add-rest-api (created 2026-01-10):
-- Delta adds "REST Endpoints" requirement
-- Searching codebase... found src/api/rest.ts
-
-Checking add-graphql (created 2026-01-15):
-- Delta adds "GraphQL Schema" requirement
-- Searching codebase... found src/api/graphql.ts
-
-Resolution: Both implemented. Will apply add-rest-api specs first,
-then add-graphql specs (chronological order, newer takes precedence).
-```
-
-**Output On Success**
-
-```
-## Bulk Archive Complete
-
-Archived N changes:
-- <change-1> -> archive/YYYY-MM-DD-<change-1>/
-- <change-2> -> archive/YYYY-MM-DD-<change-2>/
-
-Spec sync summary:
-- N delta specs synced to main specs
-- No conflicts (or: M conflicts resolved)
-```
-
-**Output On Partial Success**
-
-```
-## Bulk Archive Complete (partial)
-
-Archived N changes:
-- <change-1> -> archive/YYYY-MM-DD-<change-1>/
-
-Skipped M changes:
-- <change-2> (user chose not to archive incomplete)
-
-Failed K changes:

-```
-
-**Output When No Changes**
-
-```
-## No Changes to Archive
-
-No active changes found. Use `/opsx:new` to create a new change.
-```
-
-**Guardrails**
-- Allow any number of changes (1+ is fine, 2+ is the typical use case)
-- Always prompt for selection, never auto-select
-- Detect spec conflicts early and resolve by checking codebase
-- When both changes are implemented, apply specs in chronological order
-- Skip spec sync only when implementation is missing (warn user)
-- Show clear per-change status before confirming

-
-**Artifact Creation Guidelines**
-
-The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
-
-Common artifact patterns:
-
-**spec-driven schema** (proposal → specs → design → tasks):

-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
-**Input**: The argument after `/opsx:explore` is whatever the user wants to think about. Could be:
-- A vague idea: "real-time collaboration"
-- A specific problem: "the auth system is getting unwieldy"
-- A change name: "add-dark-mode" (to explore in context of that change)
-- A comparison: "postgres vs sqlite for this"
-- Nothing (just enter explore mode)
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-If the user mentioned a specific change name, read its artifacts for context.
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create one?"
-  → Can transition to `/opsx:new` or `/opsx:ff`
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Read existing artifacts for context**
-   - `openspec/changes/<name>/proposal.md`
-   - `openspec/changes/<name>/design.md`
-   - `openspec/changes/<name>/tasks.md`
-   - etc.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-   | Insight Type | Where to Capture |
-   |--------------|------------------|
-   | New requirement discovered | `specs/<capability>/spec.md` |
-   | Requirement changed | `specs/<capability>/spec.md` |
-   | Design decision made | `design.md` |
-   | Scope changed | `proposal.md` |
-   | New work identified | `tasks.md` |
-   | Assumption invalidated | Relevant artifact |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----
-
-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into action**: "Ready to start? `/opsx:new` or `/opsx:ff`"
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When things crystallize, you might offer a summary - but it's optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

-
-1. **If no input provided, ask what they want to build**

-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."

-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change at `openspec/changes/<name>/`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash

-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `outputPath`: Where to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "✓ Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-

-Before starting, check if OpenSpec is initialized:
-
-```bash
-openspec status --json 2>&1 || echo "NOT_INITIALIZED"
-```
-
-**If not initialized:**

-## Welcome to OpenSpec!
-
-I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
-
-**What we'll do:**
-1. Pick a small, real task in your codebase
-2. Explore the problem briefly
-3. Create a change (the container for our work)
-4. Build the artifacts: proposal → specs → design → tasks
-5. Implement the tasks
-6. Archive the completed change
-
-**Time:** ~15-20 minutes
-
-Let's start by finding something to work on.
-```
-
----
-
-## Phase 2: Task Selection
-
-### Codebase Analysis
-
-Scan the codebase for small improvement opportunities. Look for:
-
-1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
-2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
-3. **Functions without tests** - Cross-reference `src/` with test directories
-4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
-5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
-6. **Missing validation** - User input handlers without validation
-
-Also check recent git activity:
-```bash
-git log --oneline -10 2>/dev/null || echo "No git history"
-```
-
-### Present Suggestions
-
-From your analysis, present 3-4 specific suggestions:
-
-```
-## Task Suggestions
-
-Based on scanning your codebase, here are some good starter tasks:
-
-**1. [Most promising task]**
-   Location: `src/path/to/file.ts:42`
-   Scope: ~1-2 files, ~20-30 lines
-   Why it's good: [brief reason]
-
-**2. [Second task]**
-   Location: `src/another/file.ts`
-   Scope: ~1 file, ~15 lines
-   Why it's good: [brief reason]
-
-**3. [Third task]**
-   Location: [location]
-   Scope: [estimate]
-   Why it's good: [brief reason]
-
-**4. Something else?**
-   Tell me what you'd like to work on.
-
-Which task interests you? (Pick a number or describe your own)
-```
-
-**If nothing found:** Fall back to asking what the user wants to build:
-> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
-
-### Scope Guardrail
-
-If the user picks or describes something too large (major feature, multi-day work):
-
-```
-That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
-
-For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
-
-**Options:**
-1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
-2. **Pick something else** - One of the other suggestions, or a different small task?
-3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
-
-What would you prefer?
-```
-
-Let the user override if they insist—this is a soft guardrail.
-
----
-
-## Phase 3: Explore Demo
-
-Once a task is selected, briefly demonstrate explore mode:
-
-```
-Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
-```
-
-Spend 1-2 minutes investigating the relevant code:
-- Read the file(s) involved
-- Draw a quick ASCII diagram if it helps
-- Note any considerations
-
-```
-## Quick Exploration
-
-[Your brief analysis—what you found, any considerations]
-
-┌─────────────────────────────────────────┐
-│   [Optional: ASCII diagram if helpful]  │
-└─────────────────────────────────────────┘
-
-Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
-
-Now let's create a change to hold our work.
-```
-
-**PAUSE** - Wait for user acknowledgment before proceeding.
-
----
-
-## Phase 4: Create the Change
-
-**EXPLAIN:**
-```
-## Creating a Change
-
-A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
-
-Let me create one for our task.
-```
-
-**DO:** Create the change with a derived kebab-case name:
-```bash
-openspec new change "<derived-name>"
-```
-
-**SHOW:**
-```
-Created: `openspec/changes/<name>/`
-
-The folder structure:
-```
-openspec/changes/<name>/
-├── proposal.md    ← Why we're doing this (empty, we'll fill it)
-├── design.md      ← How we'll build it (empty)
-├── specs/         ← Detailed requirements (empty)
-└── tasks.md       ← Implementation checklist (empty)
-```
-
-Now let's fill in the first artifact—the proposal.
-```
-
----
-
-## Phase 5: Proposal
-
-**EXPLAIN:**
-```
-## The Proposal
-
-The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
-
-I'll draft one based on our task.
-```
-
-**DO:** Draft the proposal content (don't save yet):
-
-```
-Here's a draft proposal:
-
----
-
-## Why
-
-[1-2 sentences explaining the problem/opportunity]
-
-## What Changes
-
-[Bullet points of what will be different]
-
-## Capabilities
-
-### New Capabilities
-- `<capability-name>`: [brief description]
-
-### Modified Capabilities
-<!-- If modifying existing behavior -->
-
-## Impact
-
-- `src/path/to/file.ts`: [what changes]
-- [other files if applicable]
-
----
-
-Does this capture the intent? I can adjust before we save it.
-```
-
-**PAUSE** - Wait for user approval/feedback.
-
-After approval, save the proposal:
-```bash
-openspec instructions proposal --change "<name>" --json
-```
-Then write the content to `openspec/changes/<name>/proposal.md`.
-
-```
-Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
-
-Next up: specs.
-```
-
----
-
-## Phase 6: Specs
-
-**EXPLAIN:**
-```
-## Specs
-
-Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
-
-For a small task like this, we might only need one spec file.
-```
-
-**DO:** Create the spec file:
-```bash
-mkdir -p openspec/changes/<name>/specs/<capability-name>
-```
-
-Draft the spec content:
-
-```
-Here's the spec:
-
----
-
-## ADDED Requirements
-
-### Requirement: <Name>
-
-<Description of what the system should do>
-
-#### Scenario: <Scenario name>
-
-- **WHEN** <trigger condition>
-- **THEN** <expected outcome>
-- **AND** <additional outcome if needed>
-
----
-
-This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
-```
-
-Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
-
----
-
-## Phase 7: Design
-
-**EXPLAIN:**
-```
-## Design
-
-The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
-
-For small changes, this might be brief. That's fine—not every change needs deep design discussion.
-```
-
-**DO:** Draft design.md:
-
-```
-Here's the design:
-
----
-
-## Context
-
-[Brief context about the current state]
-
-## Goals / Non-Goals
-
-**Goals:**
-- [What we're trying to achieve]
-
-**Non-Goals:**
-- [What's explicitly out of scope]
-
-## Decisions
-
-### Decision 1: [Key decision]
-
-[Explanation of approach and rationale]
-
----
-
-For a small task, this captures the key decisions without over-engineering.
-```
-
-Save to `openspec/changes/<name>/design.md`.
-
----
-
-## Phase 8: Tasks
-
-**EXPLAIN:**
-```
-## Tasks
-
-Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
-
-These should be small, clear, and in logical order.
-```
-
-**DO:** Generate tasks based on specs and design:
-
-```
-Here are the implementation tasks:
-
----
-
-## 1. [Category or file]
-
-- [ ] 1.1 [Specific task]
-- [ ] 1.2 [Specific task]
-
-## 2. Verify
-
-- [ ] 2.1 [Verification step]
-
----
-
-Each checkbox becomes a unit of work in the apply phase. Ready to implement?
-```
-
-**PAUSE** - Wait for user to confirm they're ready to implement.
-
-Save to `openspec/changes/<name>/tasks.md`.
-
----
-
-## Phase 9: Apply (Implementation)
-
-**EXPLAIN:**
-```
-## Implementation
-
-Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
-```
-
-**DO:** For each task:
-
-1. Announce: "Working on task N: [description]"
-2. Implement the change in the codebase
-3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
-4. Mark complete in tasks.md: `- [ ]` → `- [x]`
-5. Brief status: "✓ Task N complete"
-
-Keep narration light—don't over-explain every line of code.
-
-After all tasks:
-
-```
-## Implementation Complete
-
-All tasks done:
-- [x] Task 1
-- [x] Task 2
-- [x] ...
-
-The change is implemented! One more step—let's archive it.
-```

-When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
-
-Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
-```
-
-**DO:**
-```bash
-openspec archive "<name>"
-```
-
-**SHOW:**
-```
-Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
-
-The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
-```

-
-## Phase 11: Recap & Next Steps
-
-```
-## Congratulations!
-
-You just completed a full OpenSpec cycle:
-
-1. **Explore** - Thought through the problem
-2. **New** - Created a change container
-3. **Proposal** - Captured WHY
-4. **Specs** - Defined WHAT in detail
-5. **Design** - Decided HOW
-6. **Tasks** - Broke it into steps
-7. **Apply** - Implemented the work
-8. **Archive** - Preserved the record
-
-This same rhythm works for any size change—a small fix or a major feature.

-## Command Reference
-
-| Command | What it does |
-|---------|--------------|
-| `/opsx:explore` | Think through problems before/during work |
-| `/opsx:new` | Start a new change, step through artifacts |
-| `/opsx:ff` | Fast-forward: create all artifacts at once |
-| `/opsx:continue` | Continue working on an existing change |
-| `/opsx:apply` | Implement tasks from a change |
-| `/opsx:verify` | Verify implementation matches artifacts |
-| `/opsx:archive` | Archive a completed change |
-
----
-
-## What's Next?
-
-Try `/opsx:new` or `/opsx:ff` on something you actually want to build. You've got the rhythm now!
-```
-
----
-
-## Graceful Exit Handling
-
-### User wants to stop mid-way
-
-If the user says they need to stop, want to pause, or seem disengaged:
-
-```
-No problem! Your change is saved at `openspec/changes/<name>/`.
-
-To pick up where we left off later:
-- `/opsx:continue <name>` - Resume artifact creation
-- `/opsx:apply <name>` - Jump to implementation (if tasks exist)
-
-The work won't be lost. Come back whenever you're ready.
-```
-
-Exit gracefully without pressure.
-
-### User just wants command reference
-
-If the user says they just want to see the commands or skip the tutorial:
-
-```
-## OpenSpec Quick Reference
-
-| Command | What it does |
-|---------|--------------|
-| `/opsx:explore` | Think through problems (no code changes) |
-| `/opsx:new <name>` | Start a new change, step by step |
-| `/opsx:ff <name>` | Fast-forward: all artifacts at once |
-| `/opsx:continue <name>` | Continue an existing change |
-| `/opsx:apply <name>` | Implement tasks |
-| `/opsx:verify <name>` | Verify implementation |
-| `/opsx:archive <name>` | Archive when done |
-
-Try `/opsx:new` to start your first change, or `/opsx:ff` if you want to move fast.
-```
-
-Exit gracefully.

-## Guardrails
-
-- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
-- **Keep narration light** during implementation—teach without lecturing
-- **Don't skip phases** even if the change is small—the goal is teaching the workflow
-- **Pause for acknowledgment** at marked points, but don't over-pause
-- **Handle exits gracefully**—never pressure the user to continue
-- **Use real codebase tasks**—don't simulate or use fake examples
-- **Adjust scope gently**—guide toward smaller tasks but respect user choice

-prompt = """
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Input**: Optionally specify a change name after `/opsx:sync` (e.g., `/opsx:sync add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Find delta specs**
-
-   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-3. **For each delta spec, apply changes to main specs**
-
-   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-4. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-description = "Verify implementation matches change artifacts before archiving"
-
-prompt = """
-Verify that an implementation matches the change artifacts (specs, tasks, design).
-
-**Input**: Optionally specify a change name after `/opsx:verify` (e.g., `/opsx:verify add-auth`). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have implementation tasks (tasks artifact exists).
-   Include the schema used for each change if available.
-   Mark changes with incomplete tasks as "(In Progress)".
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifacts exist for this change
-
-3. **Get the change directory and load artifacts**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns the change directory and context files. Read all available artifacts from `contextFiles`.
-
-4. **Initialize verification report structure**
-
-   Create a report structure with three dimensions:
-   - **Completeness**: Track tasks and spec coverage
-   - **Correctness**: Track requirement implementation and scenario coverage
-   - **Coherence**: Track design adherence and pattern consistency
-
-   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
-
-5. **Verify Completeness**
-
-   **Task Completion**:
-   - If tasks.md exists in contextFiles, read it
-   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
-   - Count complete vs total tasks
-   - If incomplete tasks exist:
-     - Add CRITICAL issue for each incomplete task
-     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
-
-   **Spec Coverage**:
-   - If delta specs exist in `openspec/changes/<name>/specs/`:
-     - Extract all requirements (marked with "### Requirement:")
-     - For each requirement:
-       - Search codebase for keywords related to the requirement
-       - Assess if implementation likely exists
-     - If requirements appear unimplemented:
-       - Add CRITICAL issue: "Requirement not found: <requirement name>"
-       - Recommendation: "Implement requirement X: <description>"
-
-6. **Verify Correctness**
-
-   **Requirement Implementation Mapping**:
-   - For each requirement from delta specs:
-     - Search codebase for implementation evidence
-     - If found, note file paths and line ranges
-     - Assess if implementation matches requirement intent
-     - If divergence detected:
-       - Add WARNING: "Implementation may diverge from spec: <details>"
-       - Recommendation: "Review <file>:<lines> against requirement X"
-
-   **Scenario Coverage**:
-   - For each scenario in delta specs (marked with "#### Scenario:"):
-     - Check if conditions are handled in code
-     - Check if tests exist covering the scenario
-     - If scenario appears uncovered:
-       - Add WARNING: "Scenario not covered: <scenario name>"
-       - Recommendation: "Add test or implementation for scenario: <description>"
-
-7. **Verify Coherence**
-
-   **Design Adherence**:
-   - If design.md exists in contextFiles:
-     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
-     - Verify implementation follows those decisions
-     - If contradiction detected:
-       - Add WARNING: "Design decision not followed: <decision>"
-       - Recommendation: "Update implementation or revise design.md to match reality"
-   - If no design.md: Skip design adherence check, note "No design.md to verify against"
-
-   **Code Pattern Consistency**:
-   - Review new code for consistency with project patterns
-   - Check file naming, directory structure, coding style
-   - If significant deviations found:
-     - Add SUGGESTION: "Code pattern deviation: <details>"
-     - Recommendation: "Consider following project pattern: <example>"
-
-8. **Generate Verification Report**
-
-   **Summary Scorecard**:
-   ```
-   ## Verification Report: <change-name>
-
-   ### Summary
-   | Dimension    | Status           |
-   |--------------|------------------|
-   | Completeness | X/Y tasks, N reqs|
-   | Correctness  | M/N reqs covered |
-   | Coherence    | Followed/Issues  |
-   ```
-
-   **Issues by Priority**:
-
-   1. **CRITICAL** (Must fix before archive):
-      - Incomplete tasks
-      - Missing requirement implementations
-      - Each with specific, actionable recommendation
-
-   2. **WARNING** (Should fix):
-      - Spec/design divergences
-      - Missing scenario coverage
-      - Each with specific recommendation
-
-   3. **SUGGESTION** (Nice to fix):
-      - Pattern inconsistencies
-      - Minor improvements
-      - Each with specific recommendation
-
-   **Final Assessment**:
-   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
-   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
-   - If all clear: "All checks passed. Ready for archive."
-
-**Verification Heuristics**
-
-- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
-- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
-- **Coherence**: Look for glaring inconsistencies, don't nitpick style
-- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
-- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
-
-**Graceful Degradation**
-
-- If only tasks.md exists: verify task completion only, skip spec/design checks
-- If tasks + specs exist: verify completeness and correctness, skip design
-- If full artifacts: verify all three dimensions
-- Always note which checks were skipped and why
-
-**Output Format**
-
-Use clear markdown with:
-- Table for summary scorecard
-- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
-- Code references in format: `file.ts:123`
-- Specific, actionable recommendations
-- No vague suggestions like "consider reviewing"

-Implement tasks from an OpenSpec change.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **Select the change**
-
-   If a name is provided, use it. Otherwise:
-   - Infer from conversation context if the user mentioned a change
-   - Auto-select if only one active change exists
-   - If ambiguous, run `openspec list --json` to get available changes and use the **AskUserQuestion tool** to let the user select
-
-   Always announce: "Using change: <name>" and how to override (e.g., `/opsx:apply <other>`).
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifact contains the tasks (typically "tasks" for spec-driven, check status for others)
-
-3. **Get apply instructions**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns:
-   - Context file paths (varies by schema - could be proposal/specs/design/tasks or spec/tests/implementation/docs)
-   - Progress (total, complete, remaining)
-   - Task list with status
-   - Dynamic instruction based on current state
-
-   **Handle states:**
-   - If `state: "blocked"` (missing artifacts): show message, suggest using openspec-continue-change
-   - If `state: "all_done"`: congratulate, suggest archive
-   - Otherwise: proceed to implementation
-
-4. **Read context files**
-
-   Read the files listed in `contextFiles` from the apply instructions output.
-   The files depend on the schema being used:
-   - **spec-driven**: proposal, specs, design, tasks
-   - Other schemas: follow the contextFiles from CLI output
-
-5. **Show current progress**
-
-   Display:
-   - Schema being used
-   - Progress: "N/M tasks complete"
-   - Remaining tasks overview
-   - Dynamic instruction from CLI
-
-6. **Implement tasks (loop until done or blocked)**
-
-   For each pending task:
-   - Show which task is being worked on
-   - Make the code changes required
-   - Keep changes minimal and focused
-   - Mark task complete in the tasks file: `- [ ]` → `- [x]`
-   - Continue to next task
-
-   **Pause if:**
-   - Task is unclear → ask for clarification
-   - Implementation reveals a design issue → suggest updating artifacts
-   - Error or blocker encountered → report and wait for guidance
-   - User interrupts
-
-7. **On completion or pause, show status**
-
-   Display:
-   - Tasks completed this session
-   - Overall progress: "N/M tasks complete"
-   - If all done: suggest archive
-   - If paused: explain why and wait for guidance
-
-**Output During Implementation**
-
-```
-## Implementing: <change-name> (schema: <schema-name>)
-
-Working on task 3/7: <task description>
-[...implementation happening...]
-✓ Task complete
-
-Working on task 4/7: <task description>
-[...implementation happening...]
-✓ Task complete
-```
-
-**Output On Completion**
-
-```
-## Implementation Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 7/7 tasks complete ✓
-
-### Completed This Session
-- [x] Task 1
-- [x] Task 2
-...
-
-All tasks complete! Ready to archive this change.
-```
-
-**Output On Pause (Issue Encountered)**
-
-```
-## Implementation Paused
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Progress:** 4/7 tasks complete
-
-### Issue Encountered
-<description of the issue>
-
-**Options:**
-1. <option 1>
-2. <option 2>
-3. Other approach
-
-What would you like to do?
-```
-
-**Guardrails**
-- Keep going through tasks until done or blocked
-- Always read context files before starting (from the apply instructions output)
-- If task is ambiguous, pause and ask before implementing
-- If implementation reveals issues, pause and suggest artifact updates
-- Keep code changes minimal and scoped to each task
-- Update task checkbox immediately after completing each task
-- Pause on errors, blockers, or unclear requirements - don't guess
-- Use contextFiles from CLI output, don't assume specific file names
-
-**Fluid Workflow Integration**
-
-This skill supports the "actions on a change" model:
-
-- **Can be invoked anytime**: Before all artifacts are done (if tasks exist), after partial implementation, interleaved with other actions
-- **Allows artifact updates**: If implementation reveals design issues, suggest updating artifacts - not phase-locked, work fluidly

-Archive a completed change in the experimental workflow.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show only active changes (not already archived).
-   Include the schema used for each change if available.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check artifact completion status**
-
-   Run `openspec status --change "<name>" --json` to check artifact completion.
-
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used
-   - `artifacts`: List of artifacts with their status (`done` or other)
-
-   **If any artifacts are not `done`:**
-   - Display warning listing incomplete artifacts
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-3. **Check task completion status**
-
-   Read the tasks file (typically `tasks.md`) to check for incomplete tasks.
-
-   Count tasks marked with `- [ ]` (incomplete) vs `- [x]` (complete).
-
-   **If incomplete tasks found:**
-   - Display warning showing count of incomplete tasks
-   - Use **AskUserQuestion tool** to confirm user wants to proceed
-   - Proceed if user confirms
-
-   **If no tasks file exists:** Proceed without task-related warning.
-
-4. **Assess delta spec sync state**
-
-   Check for delta specs at `openspec/changes/<name>/specs/`. If none exist, proceed without sync prompt.
-
-   **If delta specs exist:**
-   - Compare each delta spec with its corresponding main spec at `openspec/specs/<capability>/spec.md`
-   - Determine what changes would be applied (adds, modifications, removals, renames)
-   - Show a combined summary before prompting
-
-   **Prompt options:**
-   - If changes needed: "Sync now (recommended)", "Archive without syncing"
-   - If already synced: "Archive now", "Sync anyway", "Cancel"
-
-   If user chooses sync, execute /opsx:sync logic (use the openspec-sync-specs skill). Proceed to archive regardless of choice.
-
-5. **Perform the archive**
-
-   Create the archive directory if it doesn't exist:
-   ```bash
-   mkdir -p openspec/changes/archive
-   ```
-
-   Generate target name using current date: `YYYY-MM-DD-<change-name>`
-
-   **Check if target already exists:**
-   - If yes: Fail with error, suggest renaming existing archive or using different date
-   - If no: Move the change directory to archive
-
-   ```bash
-   mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-   ```
-
-6. **Display summary**
-
-   Show archive completion summary including:
-   - Change name
-   - Schema that was used
-   - Archive location
-   - Whether specs were synced (if applicable)
-   - Note about any warnings (incomplete artifacts/tasks)
-
-**Output On Success**
-
-```
-## Archive Complete
-
-**Change:** <change-name>
-**Schema:** <schema-name>
-**Archived to:** openspec/changes/archive/YYYY-MM-DD-<name>/
-**Specs:** ✓ Synced to main specs (or "No delta specs" or "Sync skipped")
-
-All artifacts complete. All tasks complete.
-```
-
-**Guardrails**
-- Always prompt for change selection if not provided
-- Use artifact graph (openspec status --json) for completion checking
-- Don't block archive on warnings - just inform and confirm
-- Preserve .openspec.yaml when moving to archive (it moves with the directory)
-- Show clear summary of what happened
-- If sync is requested, use openspec-sync-specs approach (agent-driven)
-- If delta specs exist, always run the sync assessment and show the combined summary before prompting

-   - Include an option for "All changes"
-   - Allow any number of selections (1+ works, 2+ is the typical use case)
-
-   **IMPORTANT**: Do NOT auto-select. Always let the user choose.
-
-3. **Batch validation - gather status for all selected changes**
-
-   For each selected change, collect:
-
-   a. **Artifact status** - Run `openspec status --change "<name>" --json`
-      - Parse `schemaName` and `artifacts` list
-      - Note which artifacts are `done` vs other states
-
-   b. **Task completion** - Read `openspec/changes/<name>/tasks.md`
-      - Count `- [ ]` (incomplete) vs `- [x]` (complete)
-      - If no tasks file exists, note as "No tasks"
-
-   c. **Delta specs** - Check `openspec/changes/<name>/specs/` directory
-      - List which capability specs exist
-      - For each, extract requirement names (lines matching `### Requirement: <name>`)
-
-4. **Detect spec conflicts**
-
-   Build a map of `capability -> [changes that touch it]`:
-
-   ```
-   auth -> [change-a, change-b]  <- CONFLICT (2+ changes)
-   api  -> [change-c]            <- OK (only 1 change)
-   ```
-
-   A conflict exists when 2+ selected changes have delta specs for the same capability.
-
-5. **Resolve conflicts agentically**
-
-   **For each conflict**, investigate the codebase:
-
-   a. **Read the delta specs** from each conflicting change to understand what each claims to add/modify
-
-   b. **Search the codebase** for implementation evidence:
-      - Look for code implementing requirements from each delta spec
-      - Check for related files, functions, or tests
-
-   c. **Determine resolution**:
-      - If only one change is actually implemented -> sync that one's specs
-      - If both implemented -> apply in chronological order (older first, newer overwrites)
-      - If neither implemented -> skip spec sync, warn user
-
-   d. **Record resolution** for each conflict:
-      - Which change's specs to apply
-      - In what order (if both)
-      - Rationale (what was found in codebase)
-
-6. **Show consolidated status table**
-
-   Display a table summarizing all changes:
-
-   ```
-   | Change               | Artifacts | Tasks | Specs   | Conflicts | Status |
-   |---------------------|-----------|-------|---------|-----------|--------|
-   | schema-management   | Done      | 5/5   | 2 delta | None      | Ready  |
-   | project-config      | Done      | 3/3   | 1 delta | None      | Ready  |
-   | add-oauth           | Done      | 4/4   | 1 delta | auth (!)  | Ready* |
-   | add-verify-skill    | 1 left    | 2/5   | None    | None      | Warn   |
-   ```
-
-   For conflicts, show the resolution:
-   ```
-   * Conflict resolution:
-     - auth spec: Will apply add-oauth then add-jwt (both implemented, chronological order)
-   ```
-
-   For incomplete changes, show warnings:
-   ```
-   Warnings:
-   - add-verify-skill: 1 incomplete artifact, 3 incomplete tasks
-   ```
-
-7. **Confirm batch operation**
-
-   Use **AskUserQuestion tool** with a single confirmation:
-
-   - "Archive N changes?" with options based on status
-   - Options might include:
-     - "Archive all N changes"
-     - "Archive only N ready changes (skip incomplete)"
-     - "Cancel"
-
-   If there are incomplete changes, make clear they'll be archived with warnings.
-
-8. **Execute archive for each confirmed change**
-
-   Process changes in the determined order (respecting conflict resolution):
-
-   a. **Sync specs** if delta specs exist:
-      - Use the openspec-sync-specs approach (agent-driven intelligent merge)
-      - For conflicts, apply in resolved order
-      - Track if sync was done
-
-   b. **Perform the archive**:
-      ```bash
-      mkdir -p openspec/changes/archive
-      mv openspec/changes/<name> openspec/changes/archive/YYYY-MM-DD-<name>
-      ```
-
-   c. **Track outcome** for each change:
-      - Success: archived successfully
-      - Failed: error during archive (record error)
-      - Skipped: user chose not to archive (if applicable)
-
-9. **Display summary**
-
-   Show final results:
-
-   ```
-   ## Bulk Archive Complete
-
-   Archived 3 changes:
-   - schema-management-cli -> archive/2026-01-19-schema-management-cli/
-   - project-config -> archive/2026-01-19-project-config/
-   - add-oauth -> archive/2026-01-19-add-oauth/
-
-   Skipped 1 change:
-   - add-verify-skill (user chose not to archive incomplete)
-
-   Spec sync summary:
-   - 4 delta specs synced to main specs
-   - 1 conflict resolved (auth: applied both in chronological order)
-   ```
-
-   If any failures:
-   ```
-   Failed 1 change:
-   - some-change: Archive directory already exists
-   ```
-
-**Conflict Resolution Examples**
-
-Example 1: Only one implemented
-```
-Conflict: specs/auth/spec.md touched by [add-oauth, add-jwt]
-
-Checking add-oauth:
-- Delta adds "OAuth Provider Integration" requirement
-- Searching codebase... found src/auth/oauth.ts implementing OAuth flow
-
-Checking add-jwt:
-- Delta adds "JWT Token Handling" requirement
-- Searching codebase... no JWT implementation found
-
-Resolution: Only add-oauth is implemented. Will sync add-oauth specs only.
-```
-
-Example 2: Both implemented
-```
-Conflict: specs/api/spec.md touched by [add-rest-api, add-graphql]
-
-Checking add-rest-api (created 2026-01-10):
-- Delta adds "REST Endpoints" requirement
-- Searching codebase... found src/api/rest.ts
-
-Checking add-graphql (created 2026-01-15):
-- Delta adds "GraphQL Schema" requirement
-- Searching codebase... found src/api/graphql.ts
-
-Resolution: Both implemented. Will apply add-rest-api specs first,
-then add-graphql specs (chronological order, newer takes precedence).
-```
-
-**Output On Success**
-
-```
-## Bulk Archive Complete
-
-Archived N changes:
-- <change-1> -> archive/YYYY-MM-DD-<change-1>/
-- <change-2> -> archive/YYYY-MM-DD-<change-2>/
-
-Spec sync summary:
-- N delta specs synced to main specs
-- No conflicts (or: M conflicts resolved)
-```
-
-**Output On Partial Success**
-
-```
-## Bulk Archive Complete (partial)
-
-Archived N changes:
-- <change-1> -> archive/YYYY-MM-DD-<change-1>/
-
-Skipped M changes:
-- <change-2> (user chose not to archive incomplete)
-
-Failed K changes:
-- <change-3>: Archive directory already exists
-```
-
-**Output When No Changes**
-
-```
-## No Changes to Archive
-
-No active changes found. Use `/opsx:new` to create a new change.
-```
-
-**Guardrails**
-- Allow any number of changes (1+ is fine, 2+ is the typical use case)
-- Always prompt for selection, never auto-select
-- Detect spec conflicts early and resolve by checking codebase
-- When both changes are implemented, apply specs in chronological order
-- Skip spec sync only when implementation is missing (warn user)
-- Show clear per-change status before confirming
-- Use single confirmation for entire batch
-- Track and report all outcomes (success/skip/fail)
-- Preserve .openspec.yaml when moving to archive
-- Archive directory target uses current date: YYYY-MM-DD-<name>
-- If archive target exists, fail that change but continue with others

-Continue working on a change by creating the next artifact.
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes sorted by most recently modified. Then use the **AskUserQuestion tool** to let the user select which change to work on.
-
-   Present the top 3-4 most recently modified changes as options, showing:
-   - Change name
-   - Schema (from `schema` field if present, otherwise "spec-driven")
-   - Status (e.g., "0/5 tasks", "complete", "no tasks")
-   - How recently it was modified (from `lastModified` field)
-
-   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check current status**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand current state. The response includes:
-   - `schemaName`: The workflow schema being used (e.g., "spec-driven")
-   - `artifacts`: Array of artifacts with their status ("done", "ready", "blocked")
-   - `isComplete`: Boolean indicating if all artifacts are complete
-
-3. **Act based on status**:
-
-   ---
-
-   **If all artifacts are complete (`isComplete: true`)**:
-   - Congratulate the user
-   - Show final status including the schema used
-   - Suggest: "All artifacts created! You can now implement this change or archive it."
-   - STOP
-
-   ---
-
-   **If artifacts are ready to create** (status shows artifacts with `status: "ready"`):
-   - Pick the FIRST artifact with `status: "ready"` from the status output
-   - Get its instructions:
-     ```bash
-     openspec instructions <artifact-id> --change "<name>" --json
-     ```
-   - Parse the JSON. The key fields are:
-     - `context`: Project background (constraints for you - do NOT include in output)
-     - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-     - `template`: The structure to use for your output file
-     - `instruction`: Schema-specific guidance
-     - `outputPath`: Where to write the artifact
-     - `dependencies`: Completed artifacts to read for context
-   - **Create the artifact file**:
-     - Read any completed dependency files for context
-     - Use `template` as the structure - fill in its sections
-     - Apply `context` and `rules` as constraints when writing - but do NOT copy them into the file
-     - Write to the output path specified in instructions
-   - Show what was created and what's now unlocked
-   - STOP after creating ONE artifact
-
-   ---
-
-   **If no artifacts are ready (all blocked)**:
-   - This shouldn't happen with a valid schema
-   - Show status and suggest checking for issues
-
-4. **After creating an artifact, show progress**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After each invocation, show:
-- Which artifact was created
-- Schema workflow being used
-- Current progress (N/M complete)
-- What artifacts are now unlocked
-- Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
-
-**Artifact Creation Guidelines**
-
-The artifact types and their purpose depend on the schema. Use the `instruction` field from the instructions output to understand what to create.
-
-Common artifact patterns:
-
-**spec-driven schema** (proposal → specs → design → tasks):
-- **proposal.md**: Ask user about the change if not clear. Fill in Why, What Changes, Capabilities, Impact.
-  - The Capabilities section is critical - each capability listed will need a spec file.
-- **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
-- **design.md**: Document technical decisions, architecture, and implementation approach.
-- **tasks.md**: Break down implementation into checkboxed tasks.
-
-For other schemas, follow the `instruction` field from the CLI output.
-
-**Guardrails**
-- Create ONE artifact per invocation
-- Always read dependency artifacts before creating a new one
-- Never skip artifacts or create out of order
-- If context is unclear, ask the user before creating
-- Verify the artifact file exists after writing before marking progress
-- Use the schema's artifact sequence, don't assume specific artifact names
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output

-name: openspec-explore
-description: Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.1.1"
----
-
-Enter explore mode. Think deeply. Visualize freely. Follow the conversation wherever it goes.
-
-**IMPORTANT: Explore mode is for thinking, not implementing.** You may read files, search code, and investigate the codebase, but you must NEVER write code or implement features. If the user asks you to implement something, remind them to exit explore mode first (e.g., start a change with `/opsx:new` or `/opsx:ff`). You MAY create OpenSpec artifacts (proposals, designs, specs) if the user asks—that's capturing thinking, not implementing.
-
-**This is a stance, not a workflow.** There are no fixed steps, no required sequence, no mandatory outputs. You're a thinking partner helping the user explore.
-
----
-
-## The Stance
-
-- **Curious, not prescriptive** - Ask questions that emerge naturally, don't follow a script
-- **Open threads, not interrogations** - Surface multiple interesting directions and let the user follow what resonates. Don't funnel them through a single path of questions.
-- **Visual** - Use ASCII diagrams liberally when they'd help clarify thinking
-- **Adaptive** - Follow interesting threads, pivot when new information emerges
-- **Patient** - Don't rush to conclusions, let the shape of the problem emerge
-- **Grounded** - Explore the actual codebase when relevant, don't just theorize
-
----
-
-## What You Might Do
-
-Depending on what the user brings, you might:
-
-**Explore the problem space**
-- Ask clarifying questions that emerge from what they said
-- Challenge assumptions
-- Reframe the problem
-- Find analogies
-
-**Investigate the codebase**
-- Map existing architecture relevant to the discussion
-- Find integration points
-- Identify patterns already in use
-- Surface hidden complexity
-
-**Compare options**
-- Brainstorm multiple approaches
-- Build comparison tables
-- Sketch tradeoffs
-- Recommend a path (if asked)
-
-**Visualize**

----
-
-## OpenSpec Awareness
-
-You have full context of the OpenSpec system. Use it naturally, don't force it.
-
-### Check for context
-
-At the start, quickly check what exists:
-```bash
-openspec list --json
-```
-
-This tells you:
-- If there are active changes
-- Their names, schemas, and status
-- What the user might be working on
-
-### When no change exists
-
-Think freely. When insights crystallize, you might offer:
-
-- "This feels solid enough to start a change. Want me to create one?"
-  → Can transition to `/opsx:new` or `/opsx:ff`
-- Or keep exploring - no pressure to formalize
-
-### When a change exists
-
-If the user mentions a change or you detect one is relevant:
-
-1. **Read existing artifacts for context**
-   - `openspec/changes/<name>/proposal.md`
-   - `openspec/changes/<name>/design.md`
-   - `openspec/changes/<name>/tasks.md`
-   - etc.
-
-2. **Reference them naturally in conversation**
-   - "Your design mentions using Redis, but we just realized SQLite fits better..."
-   - "The proposal scopes this to premium users, but we're now thinking everyone..."
-
-3. **Offer to capture when decisions are made**
-
-   | Insight Type | Where to Capture |
-   |--------------|------------------|
-   | New requirement discovered | `specs/<capability>/spec.md` |
-   | Requirement changed | `specs/<capability>/spec.md` |
-   | Design decision made | `design.md` |
-   | Scope changed | `proposal.md` |
-   | New work identified | `tasks.md` |
-   | Assumption invalidated | Relevant artifact |
-
-   Example offers:
-   - "That's a design decision. Capture it in design.md?"
-   - "This is a new requirement. Add it to specs?"
-   - "This changes scope. Update the proposal?"
-
-4. **The user decides** - Offer and move on. Don't pressure. Don't auto-capture.
-
----
-
-## What You Don't Have To Do
-
-- Follow a script
-- Ask the same questions every time
-- Produce a specific artifact
-- Reach a conclusion
-- Stay on topic if a tangent is valuable
-- Be brief (this is thinking time)
-
----

-## Ending Discovery
-
-There's no required ending. Discovery might:
-
-- **Flow into action**: "Ready to start? /opsx:new or /opsx:ff"
-- **Result in artifact updates**: "Updated design.md with these decisions"
-- **Just provide clarity**: User has what they need, moves on
-- **Continue later**: "We can pick this up anytime"
-
-When it feels like things are crystallizing, you might summarize:
-
-```
-## What We Figured Out
-
-**The problem**: [crystallized understanding]
-
-**The approach**: [if one emerged]
-
-**Open questions**: [if any remain]
-
-**Next steps** (if ready):
-- Create a change: /opsx:new <name>
-- Fast-forward to tasks: /opsx:ff <name>
-- Keep exploring: just keep talking
-```
-
-But this summary is optional. Sometimes the thinking IS the value.
-
----
-
-## Guardrails
-
-- **Don't implement** - Never write code or implement features. Creating OpenSpec artifacts is fine, writing application code is not.
-- **Don't fake understanding** - If something is unclear, dig deeper
-- **Don't rush** - Discovery is thinking time, not task time
-- **Don't force structure** - Let patterns emerge naturally
-- **Don't auto-capture** - Offer to save insights, don't just do it
-- **Do visualize** - A good diagram is worth many paragraphs
-- **Do explore the codebase** - Ground discussions in reality
-- **Do question assumptions** - Including the user's and your own

----
-
-Fast-forward through artifact creation - generate everything needed to start implementation in one go.
-
-**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
-
-**Steps**
-
-1. **If no clear input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   This creates a scaffolded change at `openspec/changes/<name>/`.
-
-3. **Get the artifact build order**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to get:
-   - `applyRequires`: array of artifact IDs needed before implementation (e.g., `["tasks"]`)
-   - `artifacts`: list of all artifacts with their status and dependencies
-
-4. **Create artifacts in sequence until apply-ready**
-
-   Use the **TodoWrite tool** to track progress through the artifacts.
-
-   Loop through artifacts in dependency order (artifacts with no pending dependencies first):
-
-   a. **For each artifact that is `ready` (dependencies satisfied)**:
-      - Get instructions:
-        ```bash
-        openspec instructions <artifact-id> --change "<name>" --json
-        ```
-      - The instructions JSON includes:
-        - `context`: Project background (constraints for you - do NOT include in output)
-        - `rules`: Artifact-specific rules (constraints for you - do NOT include in output)
-        - `template`: The structure to use for your output file
-        - `instruction`: Schema-specific guidance for this artifact type
-        - `outputPath`: Where to write the artifact
-        - `dependencies`: Completed artifacts to read for context
-      - Read any completed dependency files for context
-      - Create the artifact file using `template` as the structure
-      - Apply `context` and `rules` as constraints - but do NOT copy them into the file
-      - Show brief progress: "✓ Created <artifact-id>"
-
-   b. **Continue until all `applyRequires` artifacts are complete**
-      - After creating each artifact, re-run `openspec status --change "<name>" --json`
-      - Check if every artifact ID in `applyRequires` has `status: "done"` in the artifacts array
-      - Stop when all `applyRequires` artifacts are done
-
-   c. **If an artifact requires user input** (unclear context):
-      - Use **AskUserQuestion tool** to clarify
-      - Then continue with creation
-
-5. **Show final status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-
-**Output**
-
-After completing all artifacts, summarize:
-- Change name and location
-- List of artifacts created with brief descriptions
-- What's ready: "All artifacts created! Ready for implementation."
-- Prompt: "Run `/opsx:apply` or ask me to implement to start working on the tasks."
-
-**Artifact Creation Guidelines**
-
-- Follow the `instruction` field from `openspec instructions` for each artifact type
-- The schema defines what each artifact should contain - follow it
-- Read dependency artifacts for context before creating new ones
-- Use `template` as the structure for your output file - fill in its sections
-- **IMPORTANT**: `context` and `rules` are constraints for YOU, not content for the file
-  - Do NOT copy `<context>`, `<rules>`, `<project_context>` blocks into the artifact
-  - These guide what you write, but should never appear in the output
-
-**Guardrails**
-- Create ALL artifacts needed for implementation (as defined by schema's `apply.requires`)
-- Always read dependency artifacts before creating a new one
-- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
-- If a change with that name already exists, suggest continuing that change instead
-- Verify each artifact file exists after writing before proceeding to next

-
-Start a new change using the experimental artifact-driven approach.
-
-**Input**: The user's request should include a change name (kebab-case) OR a description of what they want to build.
-
-**Steps**
-
-1. **If no clear input provided, ask what they want to build**
-
-   Use the **AskUserQuestion tool** (open-ended, no preset options) to ask:
-   > "What change do you want to work on? Describe what you want to build or fix."
-
-   From their description, derive a kebab-case name (e.g., "add user authentication" → `add-user-auth`).
-
-   **IMPORTANT**: Do NOT proceed without understanding what the user wants to build.
-
-2. **Determine the workflow schema**
-
-   Use the default schema (omit `--schema`) unless the user explicitly requests a different workflow.
-
-   **Use a different schema only if the user mentions:**
-   - A specific schema name → use `--schema <name>`
-   - "show workflows" or "what workflows" → run `openspec schemas --json` and let them choose
-
-   **Otherwise**: Omit `--schema` to use the default.
-
-3. **Create the change directory**
-   ```bash
-   openspec new change "<name>"
-   ```
-   Add `--schema <name>` only if the user requested a specific workflow.
-   This creates a scaffolded change at `openspec/changes/<name>/` with the selected schema.
-
-4. **Show the artifact status**
-   ```bash
-   openspec status --change "<name>"
-   ```
-   This shows which artifacts need to be created and which are ready (dependencies satisfied).
-
-5. **Get instructions for the first artifact**
-   The first artifact depends on the schema (e.g., `proposal` for spec-driven).
-   Check the status output to find the first artifact with status "ready".
-   ```bash
-   openspec instructions <first-artifact-id> --change "<name>"
-   ```
-   This outputs the template and context for creating the first artifact.
-
-6. **STOP and wait for user direction**
-
-**Output**
-
-After completing the steps, summarize:
-- Change name and location
-- Schema/workflow being used and its artifact sequence
-- Current status (0/N artifacts complete)
-- The template for the first artifact
-- Prompt: "Ready to create the first artifact? Just describe what this change is about and I'll draft it, or ask me to continue."
-
-**Guardrails**
-- Do NOT create any artifacts yet - just show the instructions
-- Do NOT advance beyond showing the first artifact template
-- If the name is invalid (not kebab-case), ask for a valid name
-- If a change with that name already exists, suggest continuing that change instead
-- Pass --schema if using a non-default workflow

-description: Guided onboarding for OpenSpec - walk through a complete workflow cycle with narration and real codebase work.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.1.1"
----
-
-Guide the user through their first complete OpenSpec workflow cycle. This is a teaching experience—you'll do real work in their codebase while explaining each step.
-
----
-
-## Preflight
-
-Before starting, check if OpenSpec is initialized:
-
-```bash
-openspec status --json 2>&1 || echo "NOT_INITIALIZED"
-```
-
-**If not initialized:**
-> OpenSpec isn't set up in this project yet. Run `openspec init` first, then come back to `/opsx:onboard`.
-
-Stop here if not initialized.
-
----
-
-## Phase 1: Welcome
-
-Display:
-
-```
-## Welcome to OpenSpec!
-
-I'll walk you through a complete change cycle—from idea to implementation—using a real task in your codebase. Along the way, you'll learn the workflow by doing it.
-
-**What we'll do:**
-1. Pick a small, real task in your codebase
-2. Explore the problem briefly
-3. Create a change (the container for our work)
-4. Build the artifacts: proposal → specs → design → tasks
-5. Implement the tasks
-6. Archive the completed change
-
-**Time:** ~15-20 minutes
-
-Let's start by finding something to work on.
-```
-
----
-
-## Phase 2: Task Selection
-
-### Codebase Analysis
-
-Scan the codebase for small improvement opportunities. Look for:
-
-1. **TODO/FIXME comments** - Search for `TODO`, `FIXME`, `HACK`, `XXX` in code files
-2. **Missing error handling** - `catch` blocks that swallow errors, risky operations without try-catch
-3. **Functions without tests** - Cross-reference `src/` with test directories
-4. **Type issues** - `any` types in TypeScript files (`: any`, `as any`)
-5. **Debug artifacts** - `console.log`, `console.debug`, `debugger` statements in non-debug code
-6. **Missing validation** - User input handlers without validation
-
-Also check recent git activity:
-```bash
-git log --oneline -10 2>/dev/null || echo "No git history"
-```
-
-### Present Suggestions
-
-From your analysis, present 3-4 specific suggestions:
-
-```
-## Task Suggestions
-
-Based on scanning your codebase, here are some good starter tasks:
-
-**1. [Most promising task]**
-   Location: `src/path/to/file.ts:42`
-   Scope: ~1-2 files, ~20-30 lines
-   Why it's good: [brief reason]
-
-**2. [Second task]**
-   Location: `src/another/file.ts`
-   Scope: ~1 file, ~15 lines
-   Why it's good: [brief reason]
-
-**3. [Third task]**
-   Location: [location]
-   Scope: [estimate]
-   Why it's good: [brief reason]
-
-**4. Something else?**
-   Tell me what you'd like to work on.
-
-Which task interests you? (Pick a number or describe your own)
-```
-
-**If nothing found:** Fall back to asking what the user wants to build:
-> I didn't find obvious quick wins in your codebase. What's something small you've been meaning to add or fix?
-
-### Scope Guardrail
-
-If the user picks or describes something too large (major feature, multi-day work):
-
-```
-That's a valuable task, but it's probably larger than ideal for your first OpenSpec run-through.
-
-For learning the workflow, smaller is better—it lets you see the full cycle without getting stuck in implementation details.
-
-**Options:**
-1. **Slice it smaller** - What's the smallest useful piece of [their task]? Maybe just [specific slice]?
-2. **Pick something else** - One of the other suggestions, or a different small task?
-3. **Do it anyway** - If you really want to tackle this, we can. Just know it'll take longer.
-
-What would you prefer?
-```
-
-Let the user override if they insist—this is a soft guardrail.
-
----
-
-## Phase 3: Explore Demo
-
-Once a task is selected, briefly demonstrate explore mode:
-
-```
-Before we create a change, let me quickly show you **explore mode**—it's how you think through problems before committing to a direction.
-```
-
-Spend 1-2 minutes investigating the relevant code:
-- Read the file(s) involved
-- Draw a quick ASCII diagram if it helps
-- Note any considerations
-
-```
-## Quick Exploration
-
-[Your brief analysis—what you found, any considerations]
-
-┌─────────────────────────────────────────┐
-│   [Optional: ASCII diagram if helpful]  │
-└─────────────────────────────────────────┘
-
-Explore mode (`/opsx:explore`) is for this kind of thinking—investigating before implementing. You can use it anytime you need to think through a problem.
-
-Now let's create a change to hold our work.
-```
-
-**PAUSE** - Wait for user acknowledgment before proceeding.
-
----
-
-## Phase 4: Create the Change
-
-**EXPLAIN:**
-```
-## Creating a Change
-
-A "change" in OpenSpec is a container for all the thinking and planning around a piece of work. It lives in `openspec/changes/<name>/` and holds your artifacts—proposal, specs, design, tasks.
-
-Let me create one for our task.
-```
-
-**DO:** Create the change with a derived kebab-case name:
-```bash
-openspec new change "<derived-name>"
-```
-
-**SHOW:**
-```
-Created: `openspec/changes/<name>/`
-
-The folder structure:
-```
-openspec/changes/<name>/
-├── proposal.md    ← Why we're doing this (empty, we'll fill it)
-├── design.md      ← How we'll build it (empty)
-├── specs/         ← Detailed requirements (empty)
-└── tasks.md       ← Implementation checklist (empty)
-```
-
-Now let's fill in the first artifact—the proposal.
-```
-
----
-
-## Phase 5: Proposal
-
-**EXPLAIN:**
-```
-## The Proposal
-
-The proposal captures **why** we're making this change and **what** it involves at a high level. It's the "elevator pitch" for the work.
-
-I'll draft one based on our task.
-```
-
-**DO:** Draft the proposal content (don't save yet):
-
-```
-Here's a draft proposal:
-
----
-
-## Why
-
-[1-2 sentences explaining the problem/opportunity]
-
-## What Changes
-
-[Bullet points of what will be different]
-
-## Capabilities
-
-### New Capabilities
-- `<capability-name>`: [brief description]
-
-### Modified Capabilities
-<!-- If modifying existing behavior -->
-
-## Impact
-
-- `src/path/to/file.ts`: [what changes]
-- [other files if applicable]
-
----
-
-Does this capture the intent? I can adjust before we save it.
-```
-
-**PAUSE** - Wait for user approval/feedback.
-
-After approval, save the proposal:
-```bash
-openspec instructions proposal --change "<name>" --json
-```
-Then write the content to `openspec/changes/<name>/proposal.md`.
-
-```
-Proposal saved. This is your "why" document—you can always come back and refine it as understanding evolves.
-
-Next up: specs.
-```
-
----
-
-## Phase 6: Specs
-
-**EXPLAIN:**
-```
-## Specs
-
-Specs define **what** we're building in precise, testable terms. They use a requirement/scenario format that makes expected behavior crystal clear.
-
-For a small task like this, we might only need one spec file.
-```
-
-**DO:** Create the spec file:
-```bash
-mkdir -p openspec/changes/<name>/specs/<capability-name>
-```
-
-Draft the spec content:
-
-```
-Here's the spec:
-
----
-
-## ADDED Requirements
-
-### Requirement: <Name>
-
-<Description of what the system should do>
-
-#### Scenario: <Scenario name>
-
-- **WHEN** <trigger condition>
-- **THEN** <expected outcome>
-- **AND** <additional outcome if needed>
-
----
-
-This format—WHEN/THEN/AND—makes requirements testable. You can literally read them as test cases.
-```
-
-Save to `openspec/changes/<name>/specs/<capability>/spec.md`.
-
----
-
-## Phase 7: Design
-
-**EXPLAIN:**
-```
-## Design
-
-The design captures **how** we'll build it—technical decisions, tradeoffs, approach.
-
-For small changes, this might be brief. That's fine—not every change needs deep design discussion.
-```
-
-**DO:** Draft design.md:
-
-```
-Here's the design:
-
----
-
-## Context
-
-[Brief context about the current state]
-
-## Goals / Non-Goals
-
-**Goals:**
-- [What we're trying to achieve]
-
-**Non-Goals:**
-- [What's explicitly out of scope]
-
-## Decisions
-
-### Decision 1: [Key decision]
-
-[Explanation of approach and rationale]
-
----
-
-For a small task, this captures the key decisions without over-engineering.
-```
-
-Save to `openspec/changes/<name>/design.md`.
-
----
-
-## Phase 8: Tasks
-
-**EXPLAIN:**
-```
-## Tasks
-
-Finally, we break the work into implementation tasks—checkboxes that drive the apply phase.
-
-These should be small, clear, and in logical order.
-```
-
-**DO:** Generate tasks based on specs and design:
-
-```
-Here are the implementation tasks:
-
----
-
-## 1. [Category or file]
-
-- [ ] 1.1 [Specific task]
-- [ ] 1.2 [Specific task]
-
-## 2. Verify
-
-- [ ] 2.1 [Verification step]
-
----
-
-Each checkbox becomes a unit of work in the apply phase. Ready to implement?
-```
-
-**PAUSE** - Wait for user to confirm they're ready to implement.
-
-Save to `openspec/changes/<name>/tasks.md`.
-
----
-
-## Phase 9: Apply (Implementation)
-
-**EXPLAIN:**
-```
-## Implementation
-
-Now we implement each task, checking them off as we go. I'll announce each one and occasionally note how the specs/design informed the approach.
-```
-
-**DO:** For each task:
-
-1. Announce: "Working on task N: [description]"
-2. Implement the change in the codebase
-3. Reference specs/design naturally: "The spec says X, so I'm doing Y"
-4. Mark complete in tasks.md: `- [ ]` → `- [x]`
-5. Brief status: "✓ Task N complete"
-
-Keep narration light—don't over-explain every line of code.
-
-After all tasks:
-
-```
-## Implementation Complete
-
-All tasks done:
-- [x] Task 1
-- [x] Task 2
-- [x] ...
-
-The change is implemented! One more step—let's archive it.
-```
-
----
-
-## Phase 10: Archive
-
-**EXPLAIN:**
-```
-## Archiving
-
-When a change is complete, we archive it. This moves it from `openspec/changes/` to `openspec/changes/archive/YYYY-MM-DD-<name>/`.
-
-Archived changes become your project's decision history—you can always find them later to understand why something was built a certain way.
-```
-
-**DO:**
-```bash
-openspec archive "<name>"
-```
-
-**SHOW:**
-```
-Archived to: `openspec/changes/archive/YYYY-MM-DD-<name>/`
-
-The change is now part of your project's history. The code is in your codebase, the decision record is preserved.
-```
-
----
-
-## Phase 11: Recap & Next Steps
-
-```
-## Congratulations!
-
-You just completed a full OpenSpec cycle:
-
-1. **Explore** - Thought through the problem
-2. **New** - Created a change container
-3. **Proposal** - Captured WHY
-4. **Specs** - Defined WHAT in detail
-5. **Design** - Decided HOW
-6. **Tasks** - Broke it into steps
-7. **Apply** - Implemented the work
-8. **Archive** - Preserved the record
-
-This same rhythm works for any size change—a small fix or a major feature.

----
-
-## Guardrails
-
-- **Follow the EXPLAIN → DO → SHOW → PAUSE pattern** at key transitions (after explore, after proposal draft, after tasks, after archive)
-- **Keep narration light** during implementation—teach without lecturing
-- **Don't skip phases** even if the change is small—the goal is teaching the workflow
-- **Pause for acknowledgment** at marked points, but don't over-pause
-- **Handle exits gracefully**—never pressure the user to continue
-- **Use real codebase tasks**—don't simulate or use fake examples
-- **Adjust scope gently**—guide toward smaller tasks but respect user choice

-description: Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.1.1"
----
-
-Sync delta specs from a change to main specs.
-
-This is an **agent-driven** operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have delta specs (under `specs/` directory).
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Find delta specs**
-
-   Look for delta spec files in `openspec/changes/<name>/specs/*/spec.md`.
-
-   Each delta spec file contains sections like:
-   - `## ADDED Requirements` - New requirements to add
-   - `## MODIFIED Requirements` - Changes to existing requirements
-   - `## REMOVED Requirements` - Requirements to remove
-   - `## RENAMED Requirements` - Requirements to rename (FROM:/TO: format)
-
-   If no delta specs found, inform user and stop.
-
-3. **For each delta spec, apply changes to main specs**
-
-   For each capability with a delta spec at `openspec/changes/<name>/specs/<capability>/spec.md`:
-
-   a. **Read the delta spec** to understand the intended changes
-
-   b. **Read the main spec** at `openspec/specs/<capability>/spec.md` (may not exist yet)
-
-   c. **Apply changes intelligently**:
-
-      **ADDED Requirements:**
-      - If requirement doesn't exist in main spec → add it
-      - If requirement already exists → update it to match (treat as implicit MODIFIED)
-
-      **MODIFIED Requirements:**
-      - Find the requirement in main spec
-      - Apply the changes - this can be:
-        - Adding new scenarios (don't need to copy existing ones)
-        - Modifying existing scenarios
-        - Changing the requirement description
-      - Preserve scenarios/content not mentioned in the delta
-
-      **REMOVED Requirements:**
-      - Remove the entire requirement block from main spec
-
-      **RENAMED Requirements:**
-      - Find the FROM requirement, rename to TO
-
-   d. **Create new main spec** if capability doesn't exist yet:
-      - Create `openspec/specs/<capability>/spec.md`
-      - Add Purpose section (can be brief, mark as TBD)
-      - Add Requirements section with the ADDED requirements
-
-4. **Show summary**
-
-   After applying all changes, summarize:
-   - Which capabilities were updated
-   - What changes were made (requirements added/modified/removed/renamed)
-
-**Delta Spec Format Reference**
-
-```markdown
-## ADDED Requirements
-
-### Requirement: New Feature
-The system SHALL do something new.
-
-#### Scenario: Basic case
-- **WHEN** user does X
-- **THEN** system does Y
-
-## MODIFIED Requirements
-
-### Requirement: Existing Feature
-#### Scenario: New scenario to add
-- **WHEN** user does A
-- **THEN** system does B
-
-## REMOVED Requirements
-
-### Requirement: Deprecated Feature
-
-## RENAMED Requirements
-
-- FROM: `### Requirement: Old Name`
-- TO: `### Requirement: New Name`
-```
-
-**Key Principle: Intelligent Merging**
-
-Unlike programmatic merging, you can apply **partial updates**:
-- To add a scenario, just include that scenario under MODIFIED - don't copy existing scenarios
-- The delta represents *intent*, not a wholesale replacement
-- Use your judgment to merge changes sensibly
-
-**Output On Success**
-
-```
-## Specs Synced: <change-name>
-
-Updated main specs:
-
-**<capability-1>**:
-- Added requirement: "New Feature"
-- Modified requirement: "Existing Feature" (added 1 scenario)
-
-**<capability-2>**:
-- Created new spec file
-- Added requirement: "Another Feature"
-
-Main specs are now updated. The change remains active - archive when implementation is complete.
-```
-
-**Guardrails**
-- Read both delta and main specs before making changes
-- Preserve existing content not mentioned in delta
-- If something is unclear, ask for clarification
-- Show what you're changing as you go
-- The operation should be idempotent - running twice should give same result

-name: openspec-verify-change
-description: Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.
-license: MIT
-compatibility: Requires openspec CLI.
-metadata:
-  author: openspec
-  version: "1.0"
-  generatedBy: "1.1.1"
----
-
-Verify that an implementation matches the change artifacts (specs, tasks, design).
-
-**Input**: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
-
-**Steps**
-
-1. **If no change name provided, prompt for selection**
-
-   Run `openspec list --json` to get available changes. Use the **AskUserQuestion tool** to let the user select.
-
-   Show changes that have implementation tasks (tasks artifact exists).
-   Include the schema used for each change if available.
-   Mark changes with incomplete tasks as "(In Progress)".
-
-   **IMPORTANT**: Do NOT guess or auto-select a change. Always let the user choose.
-
-2. **Check status to understand the schema**
-   ```bash
-   openspec status --change "<name>" --json
-   ```
-   Parse the JSON to understand:
-   - `schemaName`: The workflow being used (e.g., "spec-driven")
-   - Which artifacts exist for this change
-
-3. **Get the change directory and load artifacts**
-
-   ```bash
-   openspec instructions apply --change "<name>" --json
-   ```
-
-   This returns the change directory and context files. Read all available artifacts from `contextFiles`.
-
-4. **Initialize verification report structure**
-
-   Create a report structure with three dimensions:
-   - **Completeness**: Track tasks and spec coverage
-   - **Correctness**: Track requirement implementation and scenario coverage
-   - **Coherence**: Track design adherence and pattern consistency
-
-   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.
-
-5. **Verify Completeness**
-
-   **Task Completion**:
-   - If tasks.md exists in contextFiles, read it
-   - Parse checkboxes: `- [ ]` (incomplete) vs `- [x]` (complete)
-   - Count complete vs total tasks
-   - If incomplete tasks exist:
-     - Add CRITICAL issue for each incomplete task
-     - Recommendation: "Complete task: <description>" or "Mark as done if already implemented"
-
-   **Spec Coverage**:
-   - If delta specs exist in `openspec/changes/<name>/specs/`:
-     - Extract all requirements (marked with "### Requirement:")
-     - For each requirement:
-       - Search codebase for keywords related to the requirement
-       - Assess if implementation likely exists
-     - If requirements appear unimplemented:
-       - Add CRITICAL issue: "Requirement not found: <requirement name>"
-       - Recommendation: "Implement requirement X: <description>"
-
-6. **Verify Correctness**
-
-   **Requirement Implementation Mapping**:
-   - For each requirement from delta specs:
-     - Search codebase for implementation evidence
-     - If found, note file paths and line ranges
-     - Assess if implementation matches requirement intent
-     - If divergence detected:
-       - Add WARNING: "Implementation may diverge from spec: <details>"
-       - Recommendation: "Review <file>:<lines> against requirement X"
-
-   **Scenario Coverage**:
-   - For each scenario in delta specs (marked with "#### Scenario:"):
-     - Check if conditions are handled in code
-     - Check if tests exist covering the scenario
-     - If scenario appears uncovered:
-       - Add WARNING: "Scenario not covered: <scenario name>"
-       - Recommendation: "Add test or implementation for scenario: <description>"
-
-7. **Verify Coherence**
-
-   **Design Adherence**:
-   - If design.md exists in contextFiles:
-     - Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
-     - Verify implementation follows those decisions
-     - If contradiction detected:
-       - Add WARNING: "Design decision not followed: <decision>"
-       - Recommendation: "Update implementation or revise design.md to match reality"
-   - If no design.md: Skip design adherence check, note "No design.md to verify against"
-
-   **Code Pattern Consistency**:
-   - Review new code for consistency with project patterns
-   - Check file naming, directory structure, coding style
-   - If significant deviations found:
-     - Add SUGGESTION: "Code pattern deviation: <details>"
-     - Recommendation: "Consider following project pattern: <example>"
-
-8. **Generate Verification Report**
-
-   **Summary Scorecard**:
-   ```
-   ## Verification Report: <change-name>
-
-   ### Summary
-   | Dimension    | Status           |
-   |--------------|------------------|
-   | Completeness | X/Y tasks, N reqs|
-   | Correctness  | M/N reqs covered |
-   | Coherence    | Followed/Issues  |
-   ```
-
-   **Issues by Priority**:
-
-   1. **CRITICAL** (Must fix before archive):
-      - Incomplete tasks
-      - Missing requirement implementations
-      - Each with specific, actionable recommendation
-
-   2. **WARNING** (Should fix):
-      - Spec/design divergences
-      - Missing scenario coverage
-      - Each with specific recommendation
-
-   3. **SUGGESTION** (Nice to fix):
-      - Pattern inconsistencies
-      - Minor improvements
-      - Each with specific recommendation
-
-   **Final Assessment**:
-   - If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
-   - If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
-   - If all clear: "All checks passed. Ready for archive."
-
-**Verification Heuristics**
-
-- **Completeness**: Focus on objective checklist items (checkboxes, requirements list)
-- **Correctness**: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
-- **Coherence**: Look for glaring inconsistencies, don't nitpick style
-- **False Positives**: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
-- **Actionability**: Every issue must have a specific recommendation with file/line references where applicable
-
-**Graceful Degradation**
-
-- If only tasks.md exists: verify task completion only, skip spec/design checks
-- If tasks + specs exist: verify completeness and correctness, skip design
-- If full artifacts: verify all three dimensions
-- Always note which checks were skipped and why
-
-**Output Format**
-
-Use clear markdown with:
-- Table for summary scorecard
-- Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
-- Code references in format: `file.ts:123`
-- Specific, actionable recommendations
-- No vague suggestions like "consider reviewing"

-## Context
-
-目前项目采用 CH32V30x 微控制器的 DVP (Digital Video Port) 外设，结合 DMA 进行红外图像数据的采集。
-为保证后续的图像处理或网络传输顺利进行，必须确认目前的 DVP 和 DMA 的配置是正确的，能够稳定、及时、无损地将红外图像帧搬运到 RAM 区，并正确处理帧中断。
-
-## Goals / Non-Goals
-
-**Goals:**
-- 验证 DVP 引脚配置、时序极性和中断设置是否符合所搭配红外传感器输出时序要求。
-- 验证 DMA 数据搬运目标地址是否正确分配且对齐，大小是否匹配一帧红外数据。
-- 确认 DMA/DVP 中断服务程序（ISR）中能有效判断帧结束和 DMA 传输完成，不发生漏帧或混乱。
-- 添加必要的轻量级日志或断点测试方法来确认取到的数据。
-
-**Non-Goals:**
-- 不涉及深度的图像识别或处理算法的开发。
-- 不涉及改变传感器本身的输出模式配置（除非影响获取数据的基础正确性）。
-
-## Decisions
-
-- **检查代码而不是立即重写**: 首先静态走查相关的配置（如 `dvp.c`, `dvp.h`），与 CH32 参考手册进行比对。
-- **内存块分配策略验证**: 确定 DVP DMA 配置的两块（双缓冲或单缓冲）地址机制，确认没有指针越界风险。
-- **测试方法**: 在帧结束中断或主循环中计算短时间内获取的有效帧数，并提取部分像素输出串口打印。
-
-## Risks / Trade-offs
-
-- [Risk] 数据量大可能引起总线或者处理迟滞 → 中断处理要足够短小，不能阻塞下一次 DMA。
-- [Risk] 直接修改中断服务可能会影响原有稳定的网络栈通信延时 → 在验证阶段避免添加过多阻塞的 printf 等操作。

-## Why
-
-The current project utilizes the DVP peripheral along with DMA to acquire infrared image data. It is crucial to verify that this configuration operates normally, correctly buffers the frames without corruption, and properly handles interrupts. Ensuring this functionality is fundamental to any downstream vision processing or data transmission.
-
-## What Changes
-
-- Comprehensive review of the DVP and DMA initialization configuration.
-- Verification of memory allocation, frame buffer sizes, and alignment for IR data.
-- Validation of the DMA complete/error interrupts and data handling routines.
-- If necessary, adding or enabling diagnostic outputs (logs) or tests to confirm data integrity.
-
-## Capabilities
-
-### New Capabilities
-- `dvp-dma-ir-capture`: Verifying and ensuring the reliable capture of infrared image data via the CH32V30x DVP peripheral and DMA channels.
-
-### Modified Capabilities
-
-## Impact
-
-- DVP and DMA initialization code (`prj/TCPClient/Debug/dvp.c`, `prj/TCPClient/Debug/dvp.h`).
-- Interrupt service routines for DMA/DVP (`prj/TCPClient/User/ch32v30x_it.c`, `prj/TCPClient/User/main.c`).
-- System memory and buffering allocations.

-
-#### Scenario: User checks IR camera status from terminal
-- **WHEN** 持续采集数据
-- **THEN** 主循环能够根据完成标志打印当前帧率及简易采集信息进行调试。

-## Context
-
-目前的系统已经具备了以太网 TCP Socket 基础和 DVP+DMA 红外数据矩阵的采集能力。然而主程序目前仅仅是将 DVP 采集到的流进行无差别循环上报，没有执行复杂的预处理逻辑。
-根据给定的架构设计文档 (`CH32二维运行结构概览.md` 与 `函数调用指南.md`)，我们需要：
-1. 导入由第三方或算法工程师提供的闭源/封装好的预处理算法库 (`Preprocess_`) 和底层 TCP 控制流协议封装 (`TcpLogic_`)。
-2. 废弃当前无差别的整帧暴力上传阻塞逻辑。
-3. 利用 `TcpTxBuffer` 的带有 offset 缓冲池机制实现零拷贝的网络流装配上传。
-4. 提供上位机参数回调和错误处理功能（如通过 `TcpLogic_RegisterConfigCallback` 和 NG 控制逻辑）。
-
-## Goals / Non-Goals
-
-**Goals:**
-- 在 `main.c` 和 `dvp.c` 中成功注册、初始化并接入 `Preprocess_xxx` 与 `TcpLogic_xxx` 的 API 生命周期。
-- 实现一个不产生内存额外拷贝 (Zero-Copy) 的缓冲区数据流，由预处理根据特定感兴趣区域截取有效温度点后，送入 TCP 模块利用预留位添加封包帧头发出。
-- 加入上位机动态热更新配置和外部气缸硬件IO回调处理。
-
-**Non-Goals:**
-- 具体的红外滑窗滤波或 TCP 报文组装的底层逻辑编写（这部分属于已封装库，只做 API 调用层面的业务整合）。
-
-## Decisions
-
-- **API 包装策略**: 为了避免 DVP 中断卡死主线程流，将 DVP 完成一帧（软触发）的逻辑校验放到业务主循环 `main` 之内。DVP 中断仅仅传递 `Line_Ready_Flag` 或全局的缓冲区双指针结束标志给主循环去执行高耗时的 `Preprocess_CheckInternalTrigger2D` 操作。
-- **内存池预分配模型**: 在全局申请两个支持偏移量设定的发送大缓存 (`TcpTxBuffer_t`) 并常驻内存，确保网络封装只需向 Buffer 首部写入 TLV 标头而无需搬运大块图像数据。
-- **配置与剔除反馈同步**: 所有与上位机的异步通信指令解析都由 `TcpLogic` 完成，主程序在此阶段只需挂载好 callback 并使用 `volatile` 配置影寄存器或标志位与主循环交互即可。
-
-## Risks / Trade-offs
-
-- [Risk] 零拷贝模型的数组越界风险 → 确保 `Preprocess` 的目标裁断 Buffer 的尺寸 > (`Target Width*Height*2 + HeadOffset`) 且首字节地址分配精确。
-- [Risk] DMA 和 主循环取图并发导致冲突 (Tearing) → 要求 DVP 在更新下一帧时利用乒乓机制避免同址同时写读，主逻辑处理时需进行资源锁屏。

-## Why
-
-当前 CH32V30x 项目已经实现了基础的 ETH 和 DVP DMA 数据采集，但缺乏核心的业务逻辑运转。根据《CH32二维运行结构概览》和《函数调用指南》，我们需要将采集到的原始图像数据进行“掩膜过滤 - 滑窗极值捕捉 - 预处理裁切”，然后通过自定义的 TCP 栈进行零拷贝封装与双流（5511控制流、5512数据流）通信，形成完整的闭环机制。
-
-## What Changes
-
-- 引入并使用 `Preprocess_` 相关 API 进行内部软触发判定与数据裁切（滑窗算法）。
-- 引入外部分配缓冲内存池 `TcpTxBuffer_t`。
-- 修改主循环/中断，加入触发判断。
-- 采用 `TcpLogic_` 库提供的封包方法替换现有的普通 TCP 发送。
-- 加入上位机动态参数热更新的更新回调 `TcpLogic_RegisterConfigCallback` 机制和 NG 外部继电器 (DO) 控制逻辑。

-

-
-### Modified Capabilities

-- 内存分配策略改变（需要保留 `HeadOffset` 并在全局开辟外部分配预留池）。
-- 依赖网络基础模块提供的 `qdx_port_tcp_send` 接口和硬件 IO 库（若要驱动剔除气缸/报警灯）。

-## Context
-
-当前 TCPClient 工程运行在裸机模式下，主循环直接轮询 WCHNET 和 DVP 任务。QDX 网络栈的 `qdx_tcp_logic` 被设计为多线程架构（3 个后台线程：1 个连接管理 + 2 个接收线程），依赖 `qdx_port.h` 定义的 11 个 HAL 函数（线程、互斥锁、延时、TCP socket），但这些函数在 `qdx_port_template.c` 中全部为空 stub。
-
-关键约束：
-- CH32V307 拥有 64KB SRAM，FreeRTOS 堆配置为 12KB
-- WCHNET 是 WCH 私有 TCP/IP 协议栈，**非 BSD socket 模型**——采用中断回调通知 + 同步轮询接收的混合模式
-- WCHNET 必须周期性调用 `WCHNET_MainTask()` 和全局中断处理才能驱动协议栈运转
-- 当前 `net_config.h` 中 `WCHNET_NUM_TCP = 1`，但双流架构（5511 控制流 + 5512 数据流）需要 2 个 TCP socket
-- FreeRTOS 的 RISC-V 移植已存在于 `prj/FreeRTOS_Core/FreeRTOS/portable/GCC/RISC-V/`
-
-## Goals / Non-Goals
-
-**Goals:**
-- 实现 `qdx_port.c` 全部 11 个 HAL 函数，使 `qdx_tcp_logic` 三线程架构实际运行
-- 将裸机主循环迁移为 FreeRTOS 多任务模型
-- 桥接 WCHNET 回调模型与 `qdx_port_tcp_recv` 的阻塞/半阻塞语义
-- 补全 `OnConfigUpdate` 和 `OnDetectionResult` 回调逻辑
-
-**Non-Goals:**
-- 不修改 `qdx_tcp_logic.c`、`qdx_protocol.c`、`qdx_preprocess.c` 的内部逻辑
-- 不实现外部硬件 DI 触发模式和连拍功能（属于后续 change）
-- 不移植到 LwIP 或其他 TCP/IP 协议栈
-
-## Decisions
-
-### Decision 1：FreeRTOS 任务划分
-
-将系统拆分为 4+3 个 FreeRTOS 任务：
-
-| 任务 | 优先级 | 栈大小 | 职责 |
-|------|--------|--------|------|
-| `task_wchnet` | 6 (高) | 1024 words | 周期调用 `WCHNET_MainTask()` + 全局中断处理 |
-| `task_business` | 5 | 1024 words | DVP 采集轮询 + 触发判定 + 预处理 + 封包发送 |
-| `tcp_mgr` | 3 | 512 words | 由 `TcpLogic_Start()` 创建，连接管理与心跳 |
-| `tcp_rx_c` | 4 | 512 words | 由 `TcpLogic_Start()` 创建，控制流接收 |
-| `tcp_rx_d` | 4 | 512 words | 由 `TcpLogic_Start()` 创建，数据流接收 |
-
-**理由**：`task_wchnet` 优先级最高，因为 WCHNET 协议栈需要及时处理底层以太网帧和 TCP 状态机；`task_business` 次之，确保 DVP 帧不丢失；TCP 后台线程优先级最低，属于非实时任务。
-
-**备选方案**：将 WCHNET 轮询放在定时器回调中而非独立任务——但 `WCHNET_MainTask()` 执行时间不确定，不适合放在中断上下文。
-
-### Decision 2：WCHNET 接收桥接方案——信号量 + 环形缓冲
-
-WCHNET 通过 `SINT_STAT_RECV` 中断通知数据到达，而 `qdx_port_tcp_recv` 被调用方期望为可阻塞/超时返回。桥接方案：
-
-1. 为每个 socket 维护一个**接收环形缓冲区**（`RxRingBuf`，2920 字节）和一个**二值信号量**（`xSemaphoreRx`）
-2. 在 `WCHNET_HandleSockInt` 的 `SINT_STAT_RECV` 分支中：调用 `WCHNET_SocketRecv()` 将数据读入 `RxRingBuf`，然后 `xSemaphoreGiveFromISR(xSemaphoreRx)`
-3. `qdx_port_tcp_recv()` 实现：先检查 `RxRingBuf` 是否有数据，有则直接拷贝返回；无则 `xSemaphoreTake(xSemaphoreRx, pdMS_TO_TICKS(100))` 阻塞等待最多 100ms，超时返回 0
-
-**理由**：这种方式让 recv 线程在无数据时让出 CPU（通过信号量阻塞），同时避免了忙等 10ms 轮询的 CPU 浪费。环形缓冲解耦了中断上下文读取和应用层消费的速率差异。
-
-**备选方案**：FreeRTOS Stream Buffer——语义更匹配但引入额外依赖，且 WCHNET 的 `SocketRecv` 已提供了长度信息，环形缓冲更简单可控。
-
-### Decision 3：Socket 映射管理
-
-WCHNET 使用 `uint8_t socketid`（0~30）标识 socket，而 `qdx_port.h` 使用 `void* qdx_socket_t` 不透明句柄。映射方案：
-
-- 维护一个静态数组 `SocketCtx_t g_sock_ctx[MAX_SOCKETS]`（MAX_SOCKETS = 2），每个元素包含：
-  - `uint8_t wchnet_sock_id` — WCHNET socket ID
-  - `uint8_t connected` — 是否已连接
-  - `RxRingBuf_t rx_ring` — 接收环形缓冲
-  - `SemaphoreHandle_t rx_sem` — 接收通知信号量
-- `qdx_port_tcp_connect()` 分配空闲的 `SocketCtx_t`，调用 `WCHNET_SocketCreat` + `WCHNET_SocketConnect`，返回 `&g_sock_ctx[i]` 作为句柄
-- `qdx_port_tcp_send/recv/close()` 从句柄中提取 `wchnet_sock_id` 操作 WCHNET API
-
-**Config 变更**：`WCHNET_NUM_TCP` 从 1 改为 2，`WCHNET_MAX_SOCKET_NUM` 相应变为 2。
-
-### Decision 4：TIM2 共享——FreeRTOS Tick + WCHNET Timer
-
-当前 TIM2 以 10ms 周期驱动 `WCHNET_TimeIsr()`。FreeRTOS 需要 2ms tick（`configTICK_RATE_HZ = 500`）。方案：
-
-- 将 TIM2 周期改为 **2ms**（匹配 FreeRTOS tick）
-- TIM2 ISR 中每次调用 `xPortSysTickHandler()`（FreeRTOS tick）
-- 设软件计数器，每累计 5 次（= 10ms）调用一次 `WCHNET_TimeIsr(WCHNETTIMERPERIOD)`
-
-**理由**：共用一个硬件定时器节省外设资源，软件分频几乎无开销。
-
-### Decision 5：`qdx_port_tcp_connect` 中的连接等待
-
-WCHNET 的 `WCHNET_SocketConnect()` 是异步的——它发起三次握手后立即返回，连接完成通过 `SINT_STAT_CONNECT` 中断通知。但 `qdx_port_tcp_connect` 语义是阻塞直到连接建立。
-
-方案：在 `SocketCtx_t` 中增加 `SemaphoreHandle_t connect_sem`。调用 `WCHNET_SocketConnect` 后 `xSemaphoreTake(connect_sem, pdMS_TO_TICKS(5000))` 阻塞。在 `SINT_STAT_CONNECT` 回调中 `xSemaphoreGive(connect_sem)`。超时返回 NULL。
-
-## Risks / Trade-offs
-
-**[RAM 占用偏紧]** → FreeRTOS 堆 12KB + 5 个任务栈约 9KB + WCHNET 内部约 10KB + 2×2920 socket 缓冲 + 2×2920 环形缓冲 + 2×10KB 发送缓冲区 ≈ 52KB / 64KB。**缓解**：严格控制任务栈大小，使用 `uxTaskGetStackHighWaterMark` 运行时监测；发送缓冲保持 10KB 不变（已经预分配）。如仍紧张可将 FreeRTOS 堆缩减至 8KB。
-
-**[WCHNET 非线程安全]** → WCHNET API 未声明线程安全性，多个 FreeRTOS 任务可能并发调用 send/recv。**缓解**：所有 WCHNET API 调用（send、recv、socket 操作）统一通过 `task_wchnet` 任务的消息队列委托执行，或者使用全局互斥锁保护。初期采用互斥锁方案，复杂度更低。
-
-**[中断上下文限制]** → `WCHNET_HandleSockInt` 在中断上下文被调用（通过 `WCHNET_HandleGlobalInt` → TIM2/ETH ISR 链），其中调用 `WCHNET_SocketRecv` 和 `xSemaphoreGiveFromISR` 必须确保安全。**缓解**：将 `WCHNET_HandleGlobalInt` 移出 ISR，改为在 `task_wchnet` 中轮询调用 `WCHNET_QueryGlobalInt`，这样 recv 回调运行在任务上下文，可安全使用 FreeRTOS API。
-
-**[双 Socket 内存增长]** → `WCHNET_NUM_TCP` 从 1 变为 2，`WCHNET_MEM_HEAP_SIZE` 和 `WCHNET_NUM_POOL_BUF` 相应增加约 3KB。**缓解**：CH32V307 有 64KB SRAM，增量可接受。

-## Why
-
-当前 QDX 网络栈的硬件抽象层 (`qdx_port_template.c`) 全部 11 个函数均为空 stub，导致 `qdx_tcp_logic` 的双流管理、心跳重连以及 `qdx_preprocess` 的并发互斥等核心功能无法真正运行。该 port 层需要对接 CH32V307 平台的 WCHNET 协议栈和 FreeRTOS 操作系统原语，使整条"采集→预处理→TCP 封包发送"的业务流水线实际贯通。
-
-## What Changes
-
-- 将 FreeRTOS 内核合入 TCPClient 工程（源码已存在于 `prj/FreeRTOS_Core/`），完成编译链接集成。
-- 新增 `qdx_port.c`（基于 `qdx_port_template.c`），使用 FreeRTOS + WCHNET API 实现全部 port 函数：
-  - 时间与延时：`qdx_port_get_tick_ms` / `qdx_port_delay_ms` → `xTaskGetTickCount` / `vTaskDelay`。
-  - 互斥锁：`qdx_port_mutex_*` → `xSemaphoreCreateMutex` / `xSemaphoreTake` / `xSemaphoreGive`。
-  - 线程：`qdx_port_thread_create` → `xTaskCreate`。
-  - TCP Socket：`qdx_port_tcp_connect` / `send` / `recv` / `close` → 封装 WCHNET 的 socket 创建、`WCHNET_SocketSend`、接收回调缓冲与 `WCHNET_SocketClose`。
-- **BREAKING**：`main.c` 主循环重构为 FreeRTOS 任务调度模型，`main()` 末尾调用 `vTaskStartScheduler()` 替代裸机 `while(1)` 轮询。
-- 补全 `OnConfigUpdate` 回调，联级调用 `Preprocess_Settings_Change` 使上位机参数热更新生效。
-- 补全 `OnDetectionResult` 回调，实现 NG 剔除 GPIO DO 输出及定时器延时复位。
-
-## Capabilities
-
-### New Capabilities
-- `freertos-wchnet-port`: 基于 FreeRTOS 和 WCHNET 实现 `qdx_port.h` 定义的全部硬件/OS 抽象接口（时间、延时、互斥锁、线程、TCP socket），使 QDX 网络栈在 CH32V307 上实际运行。
-
-### Modified Capabilities
-- `tcp-stream-logic`: 回调实现补全——`ConfigUpdateCallback_t` 内联级调用 `Preprocess_Settings_Change`；`DetectionResultCallback_t` 内驱动 DO GPIO 执行 NG 剔除动作及定时复位。
-
-## Impact
-
-- **构建系统**：TCPClient 工程需链接 FreeRTOS 源文件（tasks.c、queue.c、list.c、timers.c、port.c、heap_4.c）和对应的 include 路径。
-- **main.c**：从裸机 `while(1)` 重构为 RTOS 多任务——主业务任务（DVP 采集 + 预处理 + 发送）、WCHNET 轮询任务、以及 `qdx_tcp_logic` 创建的 3 个后台线程。
-- **内存**：FreeRTOS 内核 + 任务栈额外占用约 8-12 KB RAM，需确认 CH32V307 64KB SRAM 余量充足。
-- **中断**：TIM2 中断需同时服务 FreeRTOS tick 和 WCHNET 定时器。
-- **依赖**：`FreeRTOSConfig.h` 需要适配 CH32V307 时钟频率与中断优先级。

-- [x] 5.3 实现 `qdx_port_tcp_connect`：分配空闲 SocketCtx → 填充 SOCK_INF（PROTO_TYPE_TCP、目标 IP/Port）→ `WCHNET_SocketCreat` → `WCHNET_SocketConnect` → `xSemaphoreTake(connect_sem, 5000ms)` 阻塞等待连接完成
-- [x] 5.4 实现 `qdx_port_tcp_send`：校验句柄有效性 → 互斥锁保护 → `WCHNET_SocketSend(ctx->wchnet_sock_id, data, &len)`
-- [x] 5.5 实现 `qdx_port_tcp_recv`：检查 rx_ring 有数据直接读取返回；否则 `xSemaphoreTake(rx_sem, 100ms)` 阻塞 → 唤醒后再次检查 rx_ring → 返回数据或 0（超时）或 <0（连接断开）
-- [x] 5.6 实现 `qdx_port_tcp_close`：`WCHNET_SocketClose(ctx->wchnet_sock_id, 0)` → 清空 rx_ring → 标记 ctx 为空闲
-
-## 6. WCHNET 中断回调改造
-
-- [x] 6.1 修改 `WCHNET_HandleSockInt` 的 `SINT_STAT_RECV` 分支：通过 wchnet_sock_id 查找对应 SocketCtx → `WCHNET_SocketRecv` 读数据写入 rx_ring → `xSemaphoreGive(rx_sem)` 通知接收线程
-- [x] 6.2 修改 `SINT_STAT_CONNECT` 分支：查找对应 SocketCtx → 标记 `connected = 1` → `xSemaphoreGive(connect_sem)` 唤醒等待线程
-- [x] 6.3 修改 `SINT_STAT_DISCONNECT` 和 `SINT_STAT_TIM_OUT` 分支：标记 `connected = 0` → `xSemaphoreGive(rx_sem)` 确保阻塞中的 recv 能被唤醒退出
-
-## 7. main.c 重构为 RTOS 多任务
-
-- [x] 7.1 新增 `task_wchnet_entry` 函数：循环调用 `WCHNET_MainTask()` + `WCHNET_QueryGlobalInt` / `WCHNET_HandleGlobalInt`，周期约 5ms
-- [x] 7.2 新增 `task_business_entry` 函数：将原 `while(1)` 中的 DVP_Task + Frame 触发判定 + 预处理 + 封包发送逻辑迁入
-- [x] 7.3 修改 `main()` 函数：保留硬件初始化（SystemCoreClockUpdate、USART、DVP_Init、TIM2_Init、ETH_LibInit）→ Preprocess_Init → TcpLogic_Init → TcpLogic_RegisterCallbacks → `xTaskCreate(task_wchnet)` → `xTaskCreate(task_business)` → `vTaskStartScheduler()`
-- [x] 7.4 删除 `main()` 中的 `while(1)` 裸机主循环
-
-## 8. 回调逻辑补全
-
-- [x] 8.1 补全 `OnConfigUpdate`：内部调用 `Preprocess_Settings_Change(cfg2d, cfg1d, common)` 将新参数同步至预处理模块
-- [x] 8.2 补全 `OnDetectionResult`：当 `isOK == 0` 时拉高 NG DO GPIO 引脚，启动 FreeRTOS 软件定时器（`xTimerCreate`）延时 `NGioDelay` ms 后在回调中拉低复位
-- [x] 8.3 初始化 NG DO GPIO 引脚为推挽输出（在 main 硬件初始化阶段添加）
-
-## 9. 验证与调试
-
-- [ ] 9.1 编译整个 TCPClient 工程，修复链接错误
-- [ ] 9.2 使用 `uxTaskGetStackHighWaterMark` 验证各任务栈余量，防止溢出
-- [ ] 9.3 连接上位机测试控制流(5511)与数据流(5512)双连接建立、心跳和重连
-- [ ] 9.4 触发一帧图像，验证完整链路：DVP 采集 → 触发判定 → 预处理提取 → TCP 封包发送 → 上位机收到数据
-- [ ] 9.5 测试上位机下发参数更新，验证 Preprocess 参数热更新生效

-## ADDED Requirements
-
-### Requirement: DVP configuration verification
-系统必须具备按预期传感器时序要求正确初始化的外设 DVP，并在捕捉时确保引脚映射和控制极性符合期望。
-
-#### Scenario: DVP Peripheral correctly starts capture
-- **WHEN** 系统启动且开启红外捕捉模式
-- **THEN** DVP 能够捕捉到有效场同步和行同步信号并进行同步
-
-### Requirement: DMA memory transport correctness
-DMA 通道必须绑定至 DVP 数据寄存器，并以与图像帧空间匹配（甚至双缓冲）的配置分配目的内存区域，地址不得非法越界。
-
-#### Scenario: Frame mapped successfully to RAM buffer
-- **WHEN** DVP 传输满一整帧
-- **THEN** DMA 完整将其写入指定的 RAM buffer 并生成 DMA 满完成中断。
-
-### Requirement: Diagnostic outputs for infrared data validation
-应当包含不阻塞中断流的轻微日志来输出当前捕捉到的前 N 个像素或帧计数，以在运行时供检查验证。
-
-#### Scenario: User checks IR camera status from terminal
-- **WHEN** 持续采集数据
-- **THEN** 主循环能够根据完成标志打印当前帧率及简易采集信息进行调试。

-memory allocators as described on the https://www.FreeRTOS.org WEB site.
-
-+ The other directories each contain files specific to a particular
-microcontroller or compiler, where the directory name denotes the compiler
-specific files the directory contains.
-
-
-
-For example, if you are interested in the [compiler] port for the [architecture]
-microcontroller, then the port specific files are contained in
-FreeRTOS/Source/Portable/[compiler]/[architecture] directory.  If this is the
-only port you are interested in then all the other directories can be
-ignored.

- * An event group is a collection of bits to which an application can assign a

- * the status of various CAN bus related events in which bit 0 might mean "A CAN
- * message has been received and is ready for processing", bit 1 might mean "The
- * application has queued a message that is ready for sending onto the CAN
- * network", and bit 2 might mean "It is time to send a SYNC message onto the
- * CAN network" etc.  A task can then test the bit values to see which events
- * are active, and optionally enter the Blocked state to wait for a specified
- * bit or a group of specified bits to be active.  To continue the CAN bus
- * example, a CAN controlling task can enter the Blocked state (and therefore
- * not consume any processing time) until either bit 0, bit 1 or bit 2 are
- * active, at which time the bit that was actually active would inform the task
- * which action it had to take (process a received message, send a message, or
- * send a SYNC).
- *
- * The event groups implementation contains intelligence to avoid race
- * conditions that would otherwise occur were an application to use a simple
- * variable for the same purpose.  This is particularly important with respect
- * to when a bit within an event group is to be cleared, and when bits have to
- * be set and then tested atomically - as is the case where event groups are
- * used to create a synchronisation point between multiple tasks (a

- * Internally, within the FreeRTOS implementation, event groups use a [small]
- * block of memory, in which the event group's structure is stored.  If an event
- * groups is created using xEventGroupCreate() then the required memory is
- * automatically dynamically allocated inside the xEventGroupCreate() function.
- * (see https://www.FreeRTOS.org/a00111.html).  If an event group is created
- * using xEventGroupCreateStatic() then the application writer must instead
- * provide the memory that will get used by the event group.
- * xEventGroupCreateStatic() therefore allows an event group to be created
- * without using any dynamic memory allocation.
- *
- * Although event groups are not related to ticks, for internal implementation
- * reasons the number of bits available for use in an event group is dependent
- * on the configUSE_16_BIT_TICKS setting in FreeRTOSConfig.h.  If

- * Create a new event group.
- *
- * Internally, within the FreeRTOS implementation, event groups use a [small]
- * block of memory, in which the event group's structure is stored.  If an event
- * groups is created using xEventGroupCreate() then the required memory is
- * automatically dynamically allocated inside the xEventGroupCreate() function.
- * (see https://www.FreeRTOS.org/a00111.html).  If an event group is created
- * using xEventGroupCreateStatic() then the application writer must instead
- * provide the memory that will get used by the event group.
- * xEventGroupCreateStatic() therefore allows an event group to be created
- * without using any dynamic memory allocation.
- *
- * Although event groups are not related to ticks, for internal implementation
- * reasons the number of bits available for use in an event group is dependent
- * on the configUSE_16_BIT_TICKS setting in FreeRTOSConfig.h.  If
- * configUSE_16_BIT_TICKS is 1 then each event group contains 8 usable bits (bit
- * 0 to bit 7).  If configUSE_16_BIT_TICKS is set to 0 then each event group has
- * 24 usable bits (bit 0 to bit 23).  The EventBits_t type is used to store
- * event bits within an event group.
- *
- * @param pxEventGroupBuffer pxEventGroupBuffer must point to a variable of type
- * StaticEventGroup_t, which will be then be used to hold the event group's data
- * structures, removing the need for the memory to be allocated dynamically.
- *
- * @return If the event group was created then a handle to the event group is
- * returned.  If pxEventGroupBuffer was NULL then NULL is returned.
- *
- * Example usage:
- * @code{c}
- *  // StaticEventGroup_t is a publicly accessible structure that has the same
- *  // size and alignment requirements as the real event group structure.  It is
- *  // provided as a mechanism for applications to know the size of the event
- *  // group (which is dependent on the architecture and configuration file
- *  // settings) without breaking the strict data hiding policy by exposing the
- *  // real event group internals.  This StaticEventGroup_t variable is passed
- *  // into the xSemaphoreCreateEventGroupStatic() function and is used to store
- *  // the event group's data structures
- *  StaticEventGroup_t xEventGroupBuffer;

- * This is the list implementation used by the scheduler.  While it is tailored
- * heavily for the schedulers needs, it is also available for use by
- * application code.
- *
- * list_ts can only store pointers to list_item_ts.  Each ListItem_t contains a
- * numeric value (xItemValue).  Most of the time the lists are sorted in
- * ascending item value order.
- *
- * Lists are created already containing one list item.  The value of this
- * item is the maximum possible that can be stored, it is therefore always at
- * the end of the list and acts as a marker.  The list member pxHead always
- * points to this marker - even though it is at the tail of the list.  This
- * is because the tail contains a wrap back pointer to the true head of
- * the list.
- *
- * In addition to it's value, each list item contains a pointer to the next
- * item in the list (pxNext), a pointer to the list it is in (pxContainer)
- * and a pointer to back to the object that contains it.  These later two
- * pointers are included for efficiency of list manipulation.  There is
- * effectively a two way link between the object containing the list item and
- * the list item itself.

- * Message buffers build functionality on top of FreeRTOS stream buffers.
- * Whereas stream buffers are used to send a continuous stream of data from one
- * task or interrupt to another, message buffers are used to send variable
- * length discrete messages from one task or interrupt to another.  Their
- * implementation is light weight, making them particularly suited for interrupt
- * to task and core to core communication scenarios.
- *
- * ***NOTE***:  Uniquely among FreeRTOS objects, the stream buffer
- * implementation (so also the message buffer implementation, as message buffers
- * are built on top of stream buffers) assumes there is only one task or
- * interrupt that will write to the buffer (the writer), and only one task or
- * interrupt that will read from the buffer (the reader).  It is safe for the
- * writer and reader to be different tasks or interrupts, but, unlike other
- * FreeRTOS objects, it is not safe to have multiple different writers or
- * multiple different readers.  If there are to be multiple different writers
- * then the application writer must place each call to a writing API function
- * (such as xMessageBufferSend()) inside a critical section and set the send
- * block time to 0.  Likewise, if there are to be multiple different readers
- * then the application writer must place each call to a reading API function
- * (such as xMessageBufferRead()) inside a critical section and set the receive
- * timeout to 0.
- *
- * Message buffers hold variable length messages.  To enable that, when a
- * message is written to the message buffer an additional sizeof( size_t ) bytes
- * are also written to store the message's length (that happens internally, with
- * the API function).  sizeof( size_t ) is typically 4 bytes on a 32-bit
- * architecture, so writing a 10 byte message to a message buffer on a 32-bit
- * architecture will actually reduce the available space in the message buffer
- * by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length
- * of the message).

- * Interrupt safe version of the API function that sends a discrete message to

- *
- * ***NOTE***:  Uniquely among FreeRTOS objects, the stream buffer
- * implementation (so also the message buffer implementation, as message buffers
- * are built on top of stream buffers) assumes there is only one task or
- * interrupt that will write to the buffer (the writer), and only one task or
- * interrupt that will read from the buffer (the reader).  It is safe for the
- * writer and reader to be different tasks or interrupts, but, unlike other
- * FreeRTOS objects, it is not safe to have multiple different writers or
- * multiple different readers.  If there are to be multiple different writers
- * then the application writer must place each call to a writing API function
- * (such as xMessageBufferSend()) inside a critical section and set the send
- * block time to 0.  Likewise, if there are to be multiple different readers
- * then the application writer must place each call to a reading API function
- * (such as xMessageBufferRead()) inside a critical section and set the receive
- * block time to 0.
- *
- * Use xMessageBufferSend() to write to a message buffer from a task.  Use
- * xMessageBufferSendFromISR() to write to a message buffer from an interrupt
- * service routine (ISR).
- *
- * @param xMessageBuffer The handle of the message buffer to which a message is
- * being sent.
- *
- * @param pvTxData A pointer to the message that is to be copied into the
- * message buffer.
- *
- * @param xDataLengthBytes The length of the message.  That is, the number of
- * bytes to copy from pvTxData into the message buffer.  When a message is
- * written to the message buffer an additional sizeof( size_t ) bytes are also
- * written to store the message's length.  sizeof( size_t ) is typically 4 bytes
- * on a 32-bit architecture, so on most 32-bit architecture setting
- * xDataLengthBytes to 20 will reduce the free space in the message buffer by 24
- * bytes (20 bytes of message data and 4 bytes to hold the message length).
- *
- * @param pxHigherPriorityTaskWoken  It is possible that a message buffer will
- * have a task blocked on it waiting for data.  Calling
- * xMessageBufferSendFromISR() can make data available, and so cause a task that
- * was waiting for data to leave the Blocked state.  If calling
- * xMessageBufferSendFromISR() causes a task to leave the Blocked state, and the
- * unblocked task has a priority higher than the currently executing task (the
- * task that was interrupted), then, internally, xMessageBufferSendFromISR()
- * will set *pxHigherPriorityTaskWoken to pdTRUE.  If
- * xMessageBufferSendFromISR() sets this value to pdTRUE, then normally a
- * context switch should be performed before the interrupt is exited.  This will
- * ensure that the interrupt returns directly to the highest priority Ready
- * state task.  *pxHigherPriorityTaskWoken should be set to pdFALSE before it
- * is passed into the function.  See the code example below for an example.
- *
- * @return The number of bytes actually written to the message buffer.  If the
- * message buffer didn't have enough free space for the message to be stored
- * then 0 is returned, otherwise xDataLengthBytes is returned.
- *
- * Example use:
- * @code{c}
- * // A message buffer that has already been created.
- * MessageBufferHandle_t xMessageBuffer;
- *
- * void vAnInterruptServiceRoutine( void )
- * {
- * size_t xBytesSent;

- * memory.  The first block is used to hold the queue's data structures.  The
- * second block is used to hold items placed into the queue.  If a queue is
- * created using xQueueCreate() then both blocks of memory are automatically
- * dynamically allocated inside the xQueueCreate() function.  (see
- * https://www.FreeRTOS.org/a00111.html).  If a queue is created using
- * xQueueCreateStatic() then the application writer must provide the memory that
- * will get used by the queue.  xQueueCreateStatic() therefore allows a queue to
- * be created without using any dynamic memory allocation.
- *
- * https://www.FreeRTOS.org/Embedded-RTOS-Queues.html
- *
- * @param uxQueueLength The maximum number of items that the queue can contain.
- *
- * @param uxItemSize The number of bytes each item in the queue will require.
- * Items are queued by copy, not by reference, so this is the number of bytes
- * that will be copied for each posted item.  Each item on the queue must be
- * the same size.
- *
- * @param pucQueueStorage If uxItemSize is not zero then
- * pucQueueStorage must point to a uint8_t array that is at least large
- * enough to hold the maximum number of items that can be in the queue at any
- * one time - which is ( uxQueueLength * uxItemsSize ) bytes.  If uxItemSize is
- * zero then pucQueueStorage can be NULL.
- *
- * @param pxQueueBuffer Must point to a variable of type StaticQueue_t, which
- * will be used to hold the queue's data structure.
- *
- * @return If the queue is created then a handle to the created queue is
- * returned.  If pxQueueBuffer is NULL then NULL is returned.
- *
- * Example usage:
- * @code{c}
- * struct AMessage
- * {
- *  char ucMessageID;
- *  char ucData[ 20 ];

- *
- * Note 2:  Blocking on a queue set that contains a mutex will not cause the

- *
- * Note 3:  An additional 4 bytes of RAM is required for each space in a every

- * @endcode
- *
- * In many usage scenarios it is faster and more memory efficient to use a
- * direct to task notification in place of a binary semaphore!
- * https://www.FreeRTOS.org/RTOS-task-notifications.html
- *
- * This old vSemaphoreCreateBinary() macro is now deprecated in favour of the
- * xSemaphoreCreateBinary() function.  Note that binary semaphores created using
- * the vSemaphoreCreateBinary() macro are created in a state such that the
- * first call to 'take' the semaphore would pass, whereas binary semaphores
- * created using xSemaphoreCreateBinary() are created in a state such that the
- * the semaphore must first be 'given' before it can be 'taken'.
- *
- * <i>Macro</i> that implements a semaphore by using the existing queue mechanism.
- * The queue length is 1 as this is a binary semaphore.  The data size is 0
- * as we don't want to actually store any data - we just want to know if the
- * queue is empty or full.
- *
- * This type of semaphore can be used for pure synchronisation between tasks or
- * between an interrupt and a task.  The semaphore need not be given back once
- * obtained, so one task/interrupt can continuously 'give' the semaphore while
- * another continuously 'takes' the semaphore.  For this reason this type of
- * semaphore does not use a priority inheritance mechanism.  For an alternative
- * that does use priority inheritance see xSemaphoreCreateMutex().
- *
- * @param xSemaphore Handle to the created semaphore.  Should be of type SemaphoreHandle_t.
- *
- * Example usage:
- * @code{c}
- * SemaphoreHandle_t xSemaphore = NULL;
- *

- * Creates a new binary semaphore instance, and returns a handle by which the

- * https://www.FreeRTOS.org/RTOS-task-notifications.html
- *
- * Internally, within the FreeRTOS implementation, binary semaphores use a block
- * of memory, in which the semaphore structure is stored.  If a binary semaphore
- * is created using xSemaphoreCreateBinary() then the required memory is
- * automatically dynamically allocated inside the xSemaphoreCreateBinary()
- * function.  (see https://www.FreeRTOS.org/a00111.html).  If a binary semaphore
- * is created using xSemaphoreCreateBinaryStatic() then the application writer
- * must provide the memory.  xSemaphoreCreateBinaryStatic() therefore allows a
- * binary semaphore to be created without using any dynamic memory allocation.
- *
- * The old vSemaphoreCreateBinary() macro is now deprecated in favour of this
- * xSemaphoreCreateBinary() function.  Note that binary semaphores created using
- * the vSemaphoreCreateBinary() macro are created in a state such that the
- * first call to 'take' the semaphore would pass, whereas binary semaphores
- * created using xSemaphoreCreateBinary() are created in a state such that the
- * the semaphore must first be 'given' before it can be 'taken'.
- *
- * This type of semaphore can be used for pure synchronisation between tasks or
- * between an interrupt and a task.  The semaphore need not be given back once
- * obtained, so one task/interrupt can continuously 'give' the semaphore while
- * another continuously 'takes' the semaphore.  For this reason this type of
- * semaphore does not use a priority inheritance mechanism.  For an alternative
- * that does use priority inheritance see xSemaphoreCreateMutex().
- *
- * @return Handle to the created semaphore, or NULL if the memory required to
- * hold the semaphore's data structures could not be allocated.

- * Stream buffers are used to send a continuous stream of data from one task or

- * multiple different readers.  If there are to be multiple different writers
- * then the application writer must place each call to a writing API function
- * (such as xStreamBufferSend()) inside a critical section and set the send
- * block time to 0.  Likewise, if there are to be multiple different readers

- * Create a new task and add it to the list of tasks that are ready to run.
- *
- * Internally, within the FreeRTOS implementation, tasks use two blocks of
- * memory.  The first block is used to hold the task's data structures.  The
- * second block is used by the task as its stack.  If a task is created using
- * xTaskCreate() then both blocks of memory are automatically dynamically
- * allocated inside the xTaskCreate() function.  (see
- * https://www.FreeRTOS.org/a00111.html).  If a task is created using
- * xTaskCreateStatic() then the application writer must provide the required
- * memory.  xTaskCreateStatic() therefore allows a task to be created without
- * using any dynamic memory allocation.
- *
- * See xTaskCreateStatic() for a version that does not use any dynamic memory
- * allocation.
- *
- * xTaskCreate() can only be used to create a task that has unrestricted
- * access to the entire microcontroller memory map.  Systems that include MPU
- * support can alternatively create an MPU constrained task using
- * xTaskCreateRestricted().
- *
- * @param pxTaskCode Pointer to the task entry function.  Tasks
- * must be implemented to never return (i.e. continuous loop).
- *
- * @param pcName A descriptive name for the task.  This is mainly used to
- * facilitate debugging.  Max length defined by configMAX_TASK_NAME_LEN - default
- * is 16.
- *
- * @param usStackDepth The size of the task stack specified as the number of
- * variables the stack can hold - not the number of bytes.  For example, if
- * the stack is 16 bits wide and usStackDepth is defined as 100, 200 bytes
- * will be allocated for stack storage.
- *
- * @param pvParameters Pointer that will be used as the parameter for the task
- * being created.
- *
- * @param uxPriority The priority at which the task should run.  Systems that
- * include MPU support can optionally create tasks in a privileged (system)
- * mode by setting bit portPRIVILEGE_BIT of the priority parameter.  For
- * example, to create a privileged task at priority 2 the uxPriority parameter
- * should be set to ( 2 | portPRIVILEGE_BIT ).
- *
- * @param pxCreatedTask Used to pass back a handle by which the created task
- * can be referenced.
- *
- * @return pdPASS if the task was successfully created and added to a ready
- * list, otherwise an error code defined in the file projdefs.h

- * Create a new task and add it to the list of tasks that are ready to run.
- *
- * Internally, within the FreeRTOS implementation, tasks use two blocks of
- * memory.  The first block is used to hold the task's data structures.  The
- * second block is used by the task as its stack.  If a task is created using
- * xTaskCreate() then both blocks of memory are automatically dynamically
- * allocated inside the xTaskCreate() function.  (see
- * https://www.FreeRTOS.org/a00111.html).  If a task is created using
- * xTaskCreateStatic() then the application writer must provide the required
- * memory.  xTaskCreateStatic() therefore allows a task to be created without
- * using any dynamic memory allocation.
- *
- * @param pxTaskCode Pointer to the task entry function.  Tasks
- * must be implemented to never return (i.e. continuous loop).
- *
- * @param pcName A descriptive name for the task.  This is mainly used to
- * facilitate debugging.  The maximum length of the string is defined by
- * configMAX_TASK_NAME_LEN in FreeRTOSConfig.h.
- *
- * @param ulStackDepth The size of the task stack specified as the number of
- * variables the stack can hold - not the number of bytes.  For example, if
- * the stack is 32-bits wide and ulStackDepth is defined as 100 then 400 bytes
- * will be allocated for stack storage.
- *
- * @param pvParameters Pointer that will be used as the parameter for the task
- * being created.
- *
- * @param uxPriority The priority at which the task will run.
- *
- * @param puxStackBuffer Must point to a StackType_t array that has at least
- * ulStackDepth indexes - the array will then be used as the task's stack,
- * removing the need for the stack to be allocated dynamically.
- *
- * @param pxTaskBuffer Must point to a variable of type StaticTask_t, which will
- * then be used to hold the task's data structures, removing the need for the
- * memory to be allocated dynamically.
- *
- * @return If neither puxStackBuffer nor pxTaskBuffer are NULL, then the task
- * will be created and a handle to the created task is returned.  If either
- * puxStackBuffer or pxTaskBuffer are NULL then the task will not be created and
- * NULL is returned.
- *
- * Example usage:
- * @code{c}
- *
- *  // Dimensions of the buffer that the task being created will use as its stack.
- *  // NOTE:  This is the number of words the stack will hold, not the number of
- *  // bytes.  For example, if each stack item is 32-bits, and this is set to 100,
- *  // then 400 bytes (100 * 32-bits) will be allocated.

- * Sends a direct to task notification to a task, with an optional value and
- * action.
- *
- * Each task has a private array of "notification values" (or 'notifications'),
- * each of which is a 32-bit unsigned integer (uint32_t).  The constant
- * configTASK_NOTIFICATION_ARRAY_ENTRIES sets the number of indexes in the
- * array, and (for backward compatibility) defaults to 1 if left undefined.
- * Prior to FreeRTOS V10.4.0 there was only one notification value per task.
- *
- * Events can be sent to a task using an intermediary object.  Examples of such
- * objects are queues, semaphores, mutexes and event groups.  Task notifications
- * are a method of sending an event directly to a task without the need for such
- * an intermediary object.
- *
- * A notification sent to a task can optionally perform an action, such as
- * update, overwrite or increment one of the task's notification values.  In
- * that way task notifications can be used to send data to a task, or be used as
- * light weight and fast binary or counting semaphores.
- *
- * A task can use xTaskNotifyWaitIndexed() or ulTaskNotifyTakeIndexed() to
- * [optionally] block to wait for a notification to be pending.  The task does
- * not consume any CPU time while it is in the Blocked state.
- *
- * A notification sent to a task will remain pending until it is cleared by the
- * task calling xTaskNotifyWaitIndexed() or ulTaskNotifyTakeIndexed() (or their
- * un-indexed equivalents).  If the task was already in the Blocked state to
- * wait for a notification when the notification arrives then the task will
- * automatically be removed from the Blocked state (unblocked) and the
- * notification cleared.
- *
- * **NOTE** Each notification within the array operates independently - a task
- * can only block on one notification within the array at a time and will not be
- * unblocked by a notification sent to any other array index.
- *
- * Backward compatibility information:
- * Prior to FreeRTOS V10.4.0 each task had a single "notification value", and
- * all task notification API functions operated on that value. Replacing the
- * single notification value with an array of notification values necessitated a
- * new set of API functions that could address specific notifications within the
- * array.  xTaskNotify() is the original API function, and remains backward
- * compatible by always operating on the notification value at index 0 in the
- * array. Calling xTaskNotify() is equivalent to calling xTaskNotifyIndexed()
- * with the uxIndexToNotify parameter set to 0.
- *
- * @param xTaskToNotify The handle of the task being notified.  The handle to a
- * task can be returned from the xTaskCreate() API function used to create the
- * task, and the handle of the currently running task can be obtained by calling
- * xTaskGetCurrentTaskHandle().
- *
- * @param uxIndexToNotify The index within the target task's array of
- * notification values to which the notification is to be sent.  uxIndexToNotify
- * must be less than configTASK_NOTIFICATION_ARRAY_ENTRIES.  xTaskNotify() does
- * not have this parameter and always sends notifications to index 0.
- *
- * @param ulValue Data that can be sent with the notification.  How the data is
- * used depends on the value of the eAction parameter.
- *
- * @param eAction Specifies how the notification updates the task's notification
- * value, if at all.  Valid values for eAction are as follows:
- *
- * eSetBits -
- * The target notification value is bitwise ORed with ulValue.
- * xTaskNotifyIndexed() always returns pdPASS in this case.
- *
- * eIncrement -
- * The target notification value is incremented.  ulValue is not used and
- * xTaskNotifyIndexed() always returns pdPASS in this case.
- *
- * eSetValueWithOverwrite -
- * The target notification value is set to the value of ulValue, even if the
- * task being notified had not yet processed the previous notification at the
- * same array index (the task already had a notification pending at that index).
- * xTaskNotifyIndexed() always returns pdPASS in this case.
- *
- * eSetValueWithoutOverwrite -
- * If the task being notified did not already have a notification pending at the
- * same array index then the target notification value is set to ulValue and
- * xTaskNotifyIndexed() will return pdPASS.  If the task being notified already
- * had a notification pending at the same array index then no action is
- * performed and pdFAIL is returned.
- *
- * eNoAction -
- * The task receives a notification at the specified array index without the
- * notification value at that index being updated.  ulValue is not used and
- * xTaskNotifyIndexed() always returns pdPASS in this case.
- *
- * pulPreviousNotificationValue -
- * Can be used to pass out the subject task's notification value before any

- *
- * A version of xTaskNotifyIndexed() that can be used from an interrupt service
- * routine (ISR).
- *
- * Each task has a private array of "notification values" (or 'notifications'),
- * each of which is a 32-bit unsigned integer (uint32_t).  The constant
- * configTASK_NOTIFICATION_ARRAY_ENTRIES sets the number of indexes in the
- * array, and (for backward compatibility) defaults to 1 if left undefined.
- * Prior to FreeRTOS V10.4.0 there was only one notification value per task.
- *
- * Events can be sent to a task using an intermediary object.  Examples of such
- * objects are queues, semaphores, mutexes and event groups.  Task notifications
- * are a method of sending an event directly to a task without the need for such
- * an intermediary object.
- *
- * A notification sent to a task can optionally perform an action, such as
- * update, overwrite or increment one of the task's notification values.  In
- * that way task notifications can be used to send data to a task, or be used as
- * light weight and fast binary or counting semaphores.
- *
- * A task can use xTaskNotifyWaitIndexed() to [optionally] block to wait for a
- * notification to be pending, or ulTaskNotifyTakeIndexed() to [optionally] block
- * to wait for a notification value to have a non-zero value.  The task does
- * not consume any CPU time while it is in the Blocked state.
- *
- * A notification sent to a task will remain pending until it is cleared by the
- * task calling xTaskNotifyWaitIndexed() or ulTaskNotifyTakeIndexed() (or their
- * un-indexed equivalents).  If the task was already in the Blocked state to
- * wait for a notification when the notification arrives then the task will
- * automatically be removed from the Blocked state (unblocked) and the
- * notification cleared.
- *
- * **NOTE** Each notification within the array operates independently - a task
- * can only block on one notification within the array at a time and will not be
- * unblocked by a notification sent to any other array index.
- *
- * Backward compatibility information:
- * Prior to FreeRTOS V10.4.0 each task had a single "notification value", and
- * all task notification API functions operated on that value. Replacing the
- * single notification value with an array of notification values necessitated a
- * new set of API functions that could address specific notifications within the
- * array.  xTaskNotifyFromISR() is the original API function, and remains
- * backward compatible by always operating on the notification value at index 0
- * within the array. Calling xTaskNotifyFromISR() is equivalent to calling
- * xTaskNotifyIndexedFromISR() with the uxIndexToNotify parameter set to 0.
- *
- * @param uxIndexToNotify The index within the target task's array of
- * notification values to which the notification is to be sent.  uxIndexToNotify
- * must be less than configTASK_NOTIFICATION_ARRAY_ENTRIES.  xTaskNotifyFromISR()
- * does not have this parameter and always sends notifications to index 0.
- *
- * @param xTaskToNotify The handle of the task being notified.  The handle to a
- * task can be returned from the xTaskCreate() API function used to create the
- * task, and the handle of the currently running task can be obtained by calling
- * xTaskGetCurrentTaskHandle().
- *
- * @param ulValue Data that can be sent with the notification.  How the data is
- * used depends on the value of the eAction parameter.
- *
- * @param eAction Specifies how the notification updates the task's notification
- * value, if at all.  Valid values for eAction are as follows:
- *
- * eSetBits -
- * The task's notification value is bitwise ORed with ulValue.  xTaskNotify()
- * always returns pdPASS in this case.
- *
- * eIncrement -
- * The task's notification value is incremented.  ulValue is not used and
- * xTaskNotify() always returns pdPASS in this case.
- *
- * eSetValueWithOverwrite -
- * The task's notification value is set to the value of ulValue, even if the
- * task being notified had not yet processed the previous notification (the
- * task already had a notification pending).  xTaskNotify() always returns
- * pdPASS in this case.
- *
- * eSetValueWithoutOverwrite -
- * If the task being notified did not already have a notification pending then
- * the task's notification value is set to ulValue and xTaskNotify() will
- * return pdPASS.  If the task being notified already had a notification
- * pending then no action is performed and pdFAIL is returned.
- *
- * eNoAction -
- * The task receives a notification without its notification value being
- * updated.  ulValue is not used and xTaskNotify() always returns pdPASS in
- * this case.
- *
- * @param pxHigherPriorityTaskWoken  xTaskNotifyFromISR() will set
- * *pxHigherPriorityTaskWoken to pdTRUE if sending the notification caused the
- * task to which the notification was sent to leave the Blocked state, and the
- * unblocked task has a priority higher than the currently running task.  If
- * xTaskNotifyFromISR() sets this value to pdTRUE then a context switch should
- * be requested before the interrupt is exited.  How a context switch is
- * requested from an ISR is dependent on the port - see the documentation page
- * for the port in use.
- *
- * @return Dependent on the value of eAction.  See the description of the
- * eAction parameter.

- * macro, or xTaskNotifyIndex() function with the eAction parameter set to

- *
- * ulTaskNotifyTakeIndexed() can either clear the task's notification value at
- * the array index specified by the uxIndexToWaitOn parameter to zero on exit,
- * in which case the notification value acts like a binary semaphore, or
- * decrement the notification value on exit, in which case the notification
- * value acts like a counting semaphore.
- *
- * A task can use ulTaskNotifyTakeIndexed() to [optionally] block to wait for
- * a notification.  The task does not consume any CPU time while it is in the

- * Where as xTaskNotifyWaitIndexed() will return when a notification is pending,

- * compatible by always operating on the notification value at index 0 in the
- * array. Calling ulTaskNotifyTake() is equivalent to calling
- * ulTaskNotifyTakeIndexed() with the uxIndexToWaitOn parameter set to 0.
- *
- * @param uxIndexToWaitOn The index within the calling task's array of
- * notification values on which the calling task will wait for a notification to
- * be non-zero.  uxIndexToWaitOn must be less than
- * configTASK_NOTIFICATION_ARRAY_ENTRIES.  xTaskNotifyTake() does
- * not have this parameter and always waits for notifications on index 0.
- *
- * @param xClearCountOnExit if xClearCountOnExit is pdFALSE then the task's

- *
- * @param xTicksToWait The maximum amount of time that the task should wait in

- * Creates a new software timer instance, and returns a handle by which the
- * created software timer can be referenced.
- *
- * Internally, within the FreeRTOS implementation, software timers use a block
- * of memory, in which the timer data structure is stored.  If a software timer
- * is created using xTimerCreate() then the required memory is automatically
- * dynamically allocated inside the xTimerCreate() function.  (see
- * https://www.FreeRTOS.org/a00111.html).  If a software timer is created using
- * xTimerCreateStatic() then the application writer must provide the memory that
- * will get used by the software timer.  xTimerCreateStatic() therefore allows a
- * software timer to be created without using any dynamic memory allocation.
- *
- * Timers are created in the dormant state.  The xTimerStart(), xTimerReset(),
- * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
- * xTimerChangePeriodFromISR() API functions can all be used to transition a
- * timer into the active state.
- *
- * @param pcTimerName A text name that is assigned to the timer.  This is done
- * purely to assist debugging.  The kernel itself only ever references a timer
- * by its handle, and never by its name.
- *
- * @param xTimerPeriodInTicks The timer period.  The time is defined in tick
- * periods so the constant portTICK_PERIOD_MS can be used to convert a time that
- * has been specified in milliseconds.  For example, if the timer must expire
- * after 100 ticks, then xTimerPeriodInTicks should be set to 100.
- * Alternatively, if the timer must expire after 500ms, then xPeriod can be set
- * to ( 500 / portTICK_PERIOD_MS ) provided configTICK_RATE_HZ is less than or
- * equal to 1000.  Time timer period must be greater than 0.
- *
- * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
- * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter.
- * If uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
- * enter the dormant state after it expires.
- *
- * @param pvTimerID An identifier that is assigned to the timer being created.
- * Typically this would be used in the timer callback function to identify which
- * timer expired when the same callback function is assigned to more than one
- * timer.
- *
- * @param pxCallbackFunction The function to call when the timer expires.
- * Callback functions must have the prototype defined by TimerCallbackFunction_t,
- * which is "void vCallbackFunction( TimerHandle_t xTimer );".
- *
- * @return If the timer is successfully created then a handle to the newly
- * created timer is returned.  If the timer cannot be created because there is
- * insufficient FreeRTOS heap remaining to allocate the timer
- * structures then NULL is returned.
- *
- * Example usage:
- * @verbatim
- * #define NUM_TIMERS 5
- *
- * // An array to hold handles to the created timers.
- * TimerHandle_t xTimers[ NUM_TIMERS ];
- *
- * // An array to hold a count of the number of times each timer expires.
- * int32_t lExpireCounters[ NUM_TIMERS ] = { 0 };
- *
- * // Define a callback function that will be used by multiple timer instances.
- * // The callback function does nothing but count the number of times the
- * // associated timer expires, and stop the timer once the timer has expired
- * // 10 times.
- * void vTimerCallback( TimerHandle_t pxTimer )
- * {
- * int32_t lArrayIndex;
- * const int32_t xMaxExpiryCountBeforeStopping = 10;
- *
- *     // Optionally do something if the pxTimer parameter is NULL.
- *     configASSERT( pxTimer );
- *
- *     // Which timer expired?
- *     lArrayIndex = ( int32_t ) pvTimerGetTimerID( pxTimer );
- *
- *     // Increment the number of times that pxTimer has expired.
- *     lExpireCounters[ lArrayIndex ] += 1;

- *
- * A version of xTimerReset() that can be called from an interrupt service
- * routine.
- *
- * @param xTimer The handle of the timer that is to be started, reset, or
- * restarted.
- *
- * @param pxHigherPriorityTaskWoken The timer service/daemon task spends most
- * of its time in the Blocked state, waiting for messages to arrive on the timer
- * command queue.  Calling xTimerResetFromISR() writes a message to the timer
- * command queue, so has the potential to transition the timer service/daemon
- * task out of the Blocked state.  If calling xTimerResetFromISR() causes the
- * timer service/daemon task to leave the Blocked state, and the timer service/
- * daemon task has a priority equal to or greater than the currently executing
- * task (the task that was interrupted), then *pxHigherPriorityTaskWoken will
- * get set to pdTRUE internally within the xTimerResetFromISR() function.  If
- * xTimerResetFromISR() sets this value to pdTRUE then a context switch should
- * be performed before the interrupt exits.
- *
- * @return pdFAIL will be returned if the reset command could not be sent to
- * the timer command queue.  pdPASS will be returned if the command was
- * successfully sent to the timer command queue.  When the command is actually
- * processed will depend on the priority of the timer service/daemon task
- * relative to other tasks in the system, although the timers expiry time is
- * relative to when xTimerResetFromISR() is actually called.  The timer service/daemon
- * task priority is set by the configTIMER_TASK_PRIORITY configuration constant.
- *
- * Example usage:
- * @verbatim
- * // This scenario assumes xBacklightTimer has already been created.  When a
- * // key is pressed, an LCD back-light is switched on.  If 5 seconds pass
- * // without a key being pressed, then the LCD back-light is switched off.  In

- * void vBacklightTimerCallback( TimerHandle_t pxTimer )

- *                                          void *pvParameter1,
- *                                          uint32_t ulParameter2,
- *                                          BaseType_t *pxHigherPriorityTaskWoken );
- *
- *
- * Used from application interrupt service routines to defer the execution of a
- * function to the RTOS daemon task (the timer service task, hence this function
- * is implemented in timers.c and is prefixed with 'Timer').
- *
- * Ideally an interrupt service routine (ISR) is kept as short as possible, but
- * sometimes an ISR either has a lot of processing to do, or needs to perform
- * processing that is not deterministic.  In these cases
- * xTimerPendFunctionCallFromISR() can be used to defer processing of a function
- * to the RTOS daemon task.
- *
- * A mechanism is provided that allows the interrupt to return directly to the
- * task that will subsequently execute the pended callback function.  This
- * allows the callback function to execute contiguously in time with the
- * interrupt - just as if the callback had executed in the interrupt itself.
- *
- * @param xFunctionToPend The function to execute from the timer service/
- * daemon task.  The function must conform to the PendedFunction_t
- * prototype.
- *
- * @param pvParameter1 The value of the callback function's first parameter.
- * The parameter has a void * type to allow it to be used to pass any type.
- * For example, unsigned longs can be cast to a void *, or the void * can be
- * used to point to a structure.
- *
- * @param ulParameter2 The value of the callback function's second parameter.
- *
- * @param pxHigherPriorityTaskWoken As mentioned above, calling this function
- * will result in a message being sent to the timer daemon task.  If the
- * priority of the timer daemon task (which is set using
- * configTIMER_TASK_PRIORITY in FreeRTOSConfig.h) is higher than the priority of
- * the currently running task (the task the interrupt interrupted) then
- * *pxHigherPriorityTaskWoken will be set to pdTRUE within
- * xTimerPendFunctionCallFromISR(), indicating that a context switch should be
- * requested before the interrupt exits.  For that reason
- * *pxHigherPriorityTaskWoken must be initialised to pdFALSE.  See the
- * example code below.
- *
- * @return pdPASS is returned if the message was successfully sent to the
- * timer daemon task, otherwise pdFALSE is returned.
- *
- * Example usage:
- * @verbatim
- *
- *  // The callback function that will execute in the context of the daemon task.
- *  // Note callback functions must all use this same prototype.
- *  void vProcessInterface( void *pvParameter1, uint32_t ulParameter2 )
- *  {
- *      BaseType_t xInterfaceToService;
- *
- *      // The interface that requires servicing is passed in the second
- *      // parameter.  The first parameter is not used in this case.
- *      xInterfaceToService = ( BaseType_t ) ulParameter2;
- *
- *      // ...Perform the processing here...
- *  }
- *
- *  // An ISR that receives data packets from multiple interfaces
- *  void vAnISR( void )
- *  {
- *      BaseType_t xInterfaceToService, xHigherPriorityTaskWoken;
- *
- *      // Query the hardware to determine which interface needs processing.
- *      xInterfaceToService = prvCheckInterfaces();
- *
- *      // The actual processing is to be deferred to a task.  Request the
- *      // vProcessInterface() callback function is executed, passing in the
- *      // number of the interface that needs processing.  The interface to
- *      // service is passed in the second parameter.  The first parameter is
- *      // not used in this case.
- *      xHigherPriorityTaskWoken = pdFALSE;
- *      xTimerPendFunctionCallFromISR( vProcessInterface, NULL, ( uint32_t ) xInterfaceToService, &xHigherPriorityTaskWoken );

- *      // switch should be requested.  The macro used is port specific and will

+## 1. 系统架构概述
+
+本系统基于 CH32V307WCU6 (RISC-V) 微控制器，运行 FreeRTOS 实时操作系统，通过 WCHNET TCP/IP 协议栈与上位机通信。系统行为完全由运行时服务器配置驱动——服务器下发 Config2D/Config1D 并设置 `Enabled=1` 后，MCU 自主执行触发检测和数据采集上报。
+
+### 硬件资源
+
+| 资源 | 配置 |
+|------|------|
+| MCU | CH32V307WCU6 (RISC-V, 144MHz) |
+| FLASH | 128KB |
+| SRAM | 192KB (Option Bytes [7:5]=110) |
+| 传感器 | Mini212G2 (256×192, Y16 原始温度) |
+| 网络 | 10M 以太网 (WCHNET) |
+| 串口波特率 | 921600 |
+
+### 软件组件
+
+| 组件 | 说明 |
+|------|------|

+| 预处理模块 | 滑窗 ROI 搜索 + 温度统计 + 自动降尺寸 |
+
+---
+
+## 2. 运行模式说明
+
+系统仅保留一个编译期宏开关 `TEST_PATTERN_MODE`，控制数据来源。所有业务功能（触发、采集、NG 输出、心跳）在两种模式下均始终启用，行为由服务器运行时配置驱动。
+
+### 两种模式对比
+
+| 对比项 | 测试模式 (`TEST_PATTERN_MODE=1`) | 正常模式 (`TEST_PATTERN_MODE=0`) |
+|--------|------|------|
+| **数据来源** | 软件生成模拟热图 (~10 FPS) | Mini212G2 传感器 DVP/DMA 采集 |
+| **硬件依赖** | 仅需网口，无需传感器 | 需连接 Mini212G2 + DVP 线缆 |
+| **初始化** | 跳过 `DVP_Init()` | 执行 DVP 初始化 |
+| **帧生成** | `task_test_pattern_entry` 任务周期填充 | DVP 行中断逐行 DMA 搬运 |
+| **默认配置** | 自动注入测试配置（2D Enabled=1, 内部触发, 80°C） | 等待服务器下发，默认不使能 |
+| **自主触发** | ✅ 立即工作（无需服务器） | ✅ 需服务器下发 Enabled=1 后激活 |
+| **TEMP_REQ** | ✅ 可用（需对应模式 Enabled=1） | ✅ 可用 |
+| **NG GPIO** | ✅ PA8 始终初始化 | ✅ PA8 始终初始化 |
+| **外部触发 GPIO** | ✅ PA0/EXTI0 始终初始化 | ✅ PA0/EXTI0 始终初始化 |
+

+
+## 4. 自主触发架构详解
+
+### 4.1 核心设计原则
+
+系统的所有业务行为由运行时服务器配置驱动，不再使用编译期功能开关：
+
+```
+服务器下发 Config2D (Enabled=1) → MCU 自主执行 2D 触发/连拍/上报
+服务器下发 Config1D (Enabled=1) → MCU 自主执行 1D 采集/上报
+两者互斥：Config2D.Enabled 优先级高于 Config1D.Enabled
+```
+
+### 4.2 主循环逻辑流程
+
+```
+task_business_entry (优先级 5, 2ms 轮询)
+    │
+    ├── [1] NG 脉冲超时检查 → 到期则拉低 PA8
+    │
+    ├── [2] DVP_Task() (仅正常模式)
+    │       ├── 行 DMA 完成 → 复制到 FrameBuffer
+    │       └── 最后一行 → Frame_Ready_Flag=1
+    │
+    ├── [3] TEMP_REQ 辅助通道（服务器按需截图）
+    │       ├── 前提：对应模式 Enabled=1
+    │       ├── is2D=1 → Preprocess_Execute() → TCP 发送 (frameType=0x02)
+    │       └── is2D=0 → send_1d_snapshot() → 30 点空间采样
+    │
+    └── [4] 自主触发主管线
+            │ 前提：Frame_Ready_Flag=1 && TcpLogic_GetLatestConfig OK
+            │
+            ├── Config2D.Enabled=1 → handle_2d_trigger()
+            │   （2D 触发状态机：消抖 → 延迟 → 连拍）
+            │
+            └── Config1D.Enabled=1 → handle_1d_trigger()
+                （1D 采集状态机：IDLE → DEBOUNCE → COLLECTING）
+```
+
+### 4.3 回调注册
+
+| 回调 | 注册函数 | 触发时机 | 处理 |
+|------|---------|---------|------|
+| `OnConfigUpdate` | `TcpLogic_RegisterConfigCallback` | 服务器下发配置 | → `Preprocess_Settings_Change()` |
+| `OnDetectionResult` | `TcpLogic_RegisterDetectionCallback` | 服务器返回检测结果 (resultStatus=0 为 NG) | → PA8 NG 脉冲 |
+| `OnTempFrameRequest` | `TcpLogic_RegisterTempFrameRequestCallback` | 服务器请求截图 | → 设置 `g_temp_req_pending` |
+

+### 5.2 关键 Config2D 字段

+```
+
+### 6.2 1D 温度采样方式
+
+每个 DVP 帧产生一个温度样本：取中心行所有像素的最大温度值（`get_1d_sample()`）。
+
+### 6.3 内部触发预环形缓冲
+
+内部触发模式维护长度为 3 的环形缓冲：
+- 每帧写入一个样本到环形缓冲
+- 当 3 个样本全部 ≥ `TriggerTempLimit` → 进入 COLLECTING 状态
+- 环形缓冲内容（最旧在前）写入采集数组前 3 位
+- 从第 4 位起继续采集
+
+### 6.4 关键 Config1D 字段
+
+| 字段 | 类型 | 1D 采集中的作用 |
+|------|------|----------------|
+| `Enabled` | u8 | 1=启用 1D 管线 |
+| `RunMode` | u8 | 0=STOP, 1=RUN, 2=NOP, 3=DEBUG |
+| `TriggerType` | u8 | 1=内部(温度), 2=外部(GPIO) |
+| `BufferSize` | u16 | 单次采集最大样本数（停止条件） |
+| `TriggerTempLimit` | i16 | 触发/采集温度阈值 (0.1°C/LSB) |
+| `HighTimerLimit` | u16 | 外部触发消抖时间 (ms) |
+| `NgCountLimit` | u8 | 连续冷点数→停止采集 |
+| `LSizeStart` | u16 | 切片左起始偏移 |
+| `RSizeStart` | u16 | 切片右侧移除点数 |
+
+### 6.5 1D 数据打包格式
+
+每个样本点 4 字节 (Little-Endian)：
+
+| 偏移 | 类型 | 说明 |
+|------|------|------|
+| 0-1 | u16 LE | TimeOffset (距采集开始的毫秒偏移) |
+| 2-3 | u16 LE | Temperature (0.1°C/LSB) |
+
+---
+
+## 7. TEMP_REQ 辅助通道
+
+TEMP_REQ 是服务器主动请求的按需截图通道，与自主触发管线独立工作：
+
+- **2D 截图**：`Preprocess_Execute()` → 滑窗搜索 → 发送 `frameType=0x02`（MASKED）
+- **1D 截图**：`send_1d_snapshot()` → 从中心行等间距采样 30 点 → 发送
+
+前提：对应模式 `Enabled=1`，否则请求被忽略并打印 `TEMP_REQ ignored`。
+
+---
+
+## 8. 测试模式详解
+
+### 8.1 启用方式
+
+```c
+#define TEST_PATTERN_MODE    1
+```
+
+编译烧录即可，**无需连接任何传感器硬件**，仅需以太网连接。
+
+### 8.2 测试图案
+
+系统自动循环生成 4 种测试图案（256×192 Y16 格式）：
+
+| 图案 | 持续帧数 | 温度范围 | 是否触发 | 用途 |
+|------|---------|---------|---------|------|
+| **对角渐变** | 20 帧 | 25.0°C → 45.0°C | 否 | 基线测试 |
+| **中心热点** | 5 帧 | 背景 28~32°C, 中心 90.0°C | 是 (>80°C) | 触发测试 |
+| **均匀温场** | 10 帧 | 35.0°C | 否 | 无触发验证 |
+| **棋盘格** | 5 帧 | 28.0°C / 85.0°C 交替 | 是 (>80°C) | ROI 搜索测试 |
+
+总周期：40 帧 ≈ 4 秒循环一次。
+
+### 8.3 自动注入测试配置
+
+测试模式启动时通过 `TcpLogic_InjectTestConfig()` 注入以下配置（走标准缓存+回调路径）：
+
+```
+Config2D:
+  Enabled       = 1           # 自动启用 2D 管线
+  TriggerMode   = 0           # 内部触发（温度检测）
+  TargetWidth   = 64          # 预处理输出 64×64
+  TargetHeight  = 64
+  TriggerRoiX/Y = 0, 0        # 全幅扫描
+  TriggerRoiW/H = 256, 192
+  TriggerCondition = 1        # 最大温度
+  TriggerTemperatureThreshold = 800   # 80.0°C
+  TriggerBurstCount = 3       # 3 帧连拍
+  TriggerInternalIntervalMs = 200
+  NGioDelay     = 200
+```
+
+> **注入路径**：`TcpLogic_InjectTestConfig()` → 内部缓存 + `has_valid_config=1` → 触发 `OnConfigUpdate` 回调 → `Preprocess_Settings_Change()`。与服务器下发配置走完全相同的路径。
+
+### 8.4 启动串口输出示例
+
+```
+TCPClient
+SystemClk:144000000

+```
+
+---
+
+## 9. 正常模式详解
+
+### 9.1 启用方式
+
+```c
+#define TEST_PATTERN_MODE    0
+```
+
+需要：
+1. Mini212G2 传感器正确连接 DVP 接口
+2. 传感器已通过 USB 预配置为 CMOS/DVP Y16 输出

+
+### 9.4 正常模式注意事项
+
+- **无默认配置**：正常模式不注入测试配置，`Preprocess_Init()` 仅设置 `TargetWidth=1, TargetHeight=1`。必须等服务器下发 Config2D/Config1D 后才能工作。
+- **传感器初始化**：模组已通过 USB 预配置，`mini212g2.h` 中 UART 配置已关闭。
+- **帧率取决于传感器**：Mini212G2 在 DVP 模式下的帧率由传感器内部配置决定。

+
+### 11.3 缓冲区容量约束
+
+```
+MAX_TCP_PAYLOAD_SIZE = 10240 字节
+HeadOffset           = 64 字节（协议头预留）
+可用像素空间         = 10240 - 64 = 10176 字节
+最大像素数           = 10176 / 2 = 5088 像素
+
+推荐安全目标尺寸:
+  64 × 64 = 4096 像素 = 8192 字节  ✓
+  71 × 71 = 5041 像素 = 10082 字节 ✓
+  72 × 72 = 5184 像素 = 10368 字节 ✗ (触发降尺寸)
+```
+
+### 11.4 自动降尺寸保护
+
+TargetWidth × TargetHeight × 2 超过可用缓冲区时，自动等比减半：
+
+```
+示例：服务器设 185×70 → 185×70×2=25900 > 10176 → 减半 → 93×35
+日志：PP: target clamped 185x70 -> 93x35 (buf=10176)
+```
+
+### 11.5 配置传递链
+
+```
+服务器 TCP 下发 TLV
+    → qdx_tcp_logic.c: parse_and_dispatch_tlv()
+    → 反序列化 → cached_cfg{2d,1d,common}
+    → OnConfigUpdate() 回调
+    → Preprocess_Settings_Change() 互斥锁更新
+    → 下次帧处理使用新配置
+```

+
+## 15. 已知注意事项
+
+### 15.1 温度单位
+
+系统统一使用 **0.1°C/LSB**：
+- 温度值 350 = 35.0°C
+- 温度值 900 = 90.0°C
+- `TEMP_RAW(deg_c) = (uint16_t)(deg_c * 10)`
+
+### 15.2 Config2D 字段区分
+
+- **Width / Height**：设备分辨率标识（如 256×192），不影响 MCU 预处理
+- **TargetWidth / TargetHeight**：预处理实际输出尺寸，**必须正确设置**
+
+### 15.3 正常模式默认目标尺寸
+
+`TargetWidth=1, TargetHeight=1`（最小默认），必须等服务器下发 Config2D 后才能正常输出。
+
+### 15.4 IP 与端口硬编码
+
+网络参数为编译期常量，更改需修改源码并重新编译：
+- MCU IP：`main.c` → `IPAddr[]`
+- 服务器 IP：`qdx_tcp_logic.c` → `SERVER_IP`
+- 端口号：`qdx_tcp_logic.c` → `CONTROL_PORT` / `DATA_PORT`
+
+### 15.5 printf 限制
+
+使用 newlib-nano，仅支持 `%d, %x, %s` 格式。所有 `uint32_t` 必须 `(int)` 强转后打印，否则 HardFault。不支持 `%u, %lu, %f`。
+
+### 15.6 双缓冲发送
+
+系统使用 A/B 交替 `TcpTxBuffer_t`，避免发送过程中缓冲区被覆盖。`use_buffer_A` 标志在每次发送后翻转。
+
+### 15.7 2D/1D 互斥
+
+主循环中 `Config2D.Enabled` 优先级高于 `Config1D.Enabled`。若两者同时 Enabled=1，仅 2D 管线运行。
