-   - Write tests in `test/*.test.js` using Node's native test runner (`node:test`, `node:assert/strict`).
+   - Test cases MUST ALWAYS be written in `test/*.test.js` before writing or modifying any functional code (filters, templates, server routes, ingestion pipeline, data loaders, scripts).

+     - **Security & Integrity:** Test path traversals, malformed JSON, unauthorized tokens, malicious payloads.
-   - **Link & Anchor Integrity:** Verify that every compiled page has zero broken internal links and that all Table of Contents anchor links resolve to valid heading IDs.

+  Use this skill sparingly when a new major function or feature has been implemented, when the user explicitly asks to verify standards, or as a debugging tool to analyze code issues. Targets only modified or relevant files via git status/diff and evaluates them against the project standards document.
+---
+
+# Standards Verification Skill
+
+This skill performs targeted architectural and stylistic compliance verification for new or modified code in this repository.
+
+> [!IMPORTANT]
+> **Invocation Policy:** Call this skill **sparingly and only when needed**.
+> **Valid Triggers:**
+> 1. A new major function or architectural feature has been implemented.
+> 2. The user asks to call it or requests standards verification.
+> 3. An error, test failure, or regression has occurred, and you are using this skill as a debugging tool to determine where the code diverges from project standards.
+
+
+---
+
+## 1. Targeted Inspection Scope (Not the Whole Codebase)
+
+Do **NOT** scan or audit the whole codebase unless specifically requested by the user or strictly necessary for whole-system refactors.
+
+Instead, narrow the scope to targeted sections using Git:
+
+1. **Check Modified Files:**
+   ```bash
+   git status -s
+   ```
+2. **Inspect Exact Changes:**
+   ```bash
+   git diff HEAD
+   ```
+   Or for staged changes:
+   ```bash
+   git diff --staged
+   ```
+3. **Identify Changed Sections:**
+   Focus only on the files, functions, templates, or styles touched in the current task.
+
+---
+
+## 2. Standards Evaluation Workflow
+
+To verify compliance, read the dedicated project standards document:
+- Authoritative document: [`.agents/standards.md`](file:///home/venus/code/blog/.agents/standards.md) (or local skill reference: [`references/standards.md`](file:///home/venus/code/blog/.agents/skills/standards-verification/references/standards.md)).
+
+Evaluate the targeted changes against the core standard pillars:
+
+1. **Design System & CSS Rules:**
+   - Are any anti-patterns present? Check for `backdrop-filter`, `box-shadow`, `text-shadow` (other than `none`), gradients, or transitions with delays/curves.
+   - Are border radii strictly bounded between `0px` and `4px`?
+   - Are colors utilizing CSS custom properties from `tokens.css`?
+   - Is styling modularized without inline `<style>` tags?
+
+2. **Templating & Eleventy Architecture:**
+   - Does post rendering adhere to layout inheritance (`base.njk` -> `post.njk`)?
+   - Are collections (`posts`, `tagList`) properly filtered using `isPostPublic`?
+   - If a post is marked `hidden`, does the layout emit `<meta name="robots" content="noindex, nofollow">`?
+
+3. **Content & Frontmatter Contracts:**
+   - Are required frontmatter keys (`title`, `date`, `tags`, `excerpt`) valid and conforming to schema length invariants?
+   - Are wikilinks and Obsidian attachments normalized?
+
+4. **Server & Security Invariants:**
+   - Does `server.js` preserve security headers (`X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`, `Referrer-Policy: strict-origin-when-cross-origin`)?
+   - Is path traversal protection in place for all file-serving and API endpoints?
+
+5. **Test-Driven Development (TDD) Invariants:**
+   - Were automated test cases written *before* functional code was modified?
+   - Are adversarial test cases included (boundary inputs, nulls, invalid configs)?
+   - Do all tests pass (`npm test`)?
+
+---
+
+## 3. Stylistic & Architectural Reporting
+
+Compile a structured report highlighting:
+- **Conformant Highlights:** Key standards cleanly satisfied.
+- **Stylistic Issues & Deviations:** Any formatting inconsistencies, unneeded inline styles, or naming anomalies.
+- **Remediation Steps:** Concrete, minimal code adjustments to bring the implementation into full compliance.
+
+---
+
+## 4. Debugging with Standards Verification
+
+When using this skill as a debugging tool to troubleshoot broken builds, failed tests, or runtime bugs:
+
+1. **Locate the Error:** Inspect test failure outputs or server logs to isolate the failing component.
+2. **Correlate with Standards:** Compare the problematic implementation against [`.agents/standards.md`](file:///home/venus/code/blog/.agents/standards.md).
+3. **Explain the Discrepancy:** Specifically identify where the code is out of touch with project standards (e.g. missing input guards for `null`, collections bypassing `isPostPublic`, un-sanitized slug paths).
+4. **Suggest Root Cause & Fix:** Suggest why those issues cause an error and provide the targeted fix.

+# Technical Blog Project Standards & Architectural Specification
+
+This document is a direct reference for the `standards-verification` skill, mirroring the authoritative project standards defined in [`.agents/standards.md`](file:///home/venus/code/blog/.agents/standards.md).
+
+---
+
+## 1. User Content Sovereignty (Highest Priority)
+- User custom writing, post titles, tags, navigation labels, and naming choices strictly supersede any boilerplate, skill instructions, or sample mockups.
+- Never overwrite, sanitize away, or rename user-authored text without explicit instruction.
+- Inconsistencies or typos in user writing must be flagged for clarification rather than unilaterally changed.
+
+---
+
+## 2. Strict Test-Driven Development (TDD) & Adversarial Verification
+- **Test-First Invariant:** Automated test cases in `test/*.test.js` MUST ALWAYS be written and established *before writing or modifying any functional code* (filters, templates, server routes, ingestion logic, build scripts). Never write functional code before tests.
+- **Mandatory Adversarial Testing:** Standard behavior for every change must include adversarial tests specifically designed to falsify assumptions (missing env vars like `SITE_DOMAIN`, null/undefined/malformed inputs, boundary values, path traversals, design rule violations).
+- **Pre-Presentation Verification Gate:** Run `npm test` before presenting the final output to the user. All test cases must pass before presenting the final output. Delivering unverified or failing code is strictly forbidden.
+
+---
+
+## 3. Design System & CSS Specification
+- **Color Palette:** Canvas `#0d0f12`, Surface `#121417`, Elevated `#1c1f26`, Borders `#2b303b`, Text `#e0e6f0`, Accents `#00f0ff` (Cyan), `#00e676` (Green), `#ffb700` (Amber), `#ff5252` (Red).
+- **Hard Anti-Patterns:**
+  - NO glassmorphism (`backdrop-filter`).
+  - NO drop shadows or glows (`box-shadow`, `text-shadow`).
+  - NO linear or radial gradients.
+  - Border-radius capped at `0px` to `4px` maximum.
+  - Transitions must be instant binary snaps (`none` or `0s`).
+- **Typography:** `IBM Plex Mono` / `JetBrains Mono` for UI and code; `Inter` for body prose.
+- **CSS Modularity:** Zero inline `<style>` tags. Decompose into `tokens.css`, `reset.css`, `layout.css`, `components/*.css`.
+
+---
+
+## 4. Templating & Eleventy Architecture
+- **Layouts & Partials:** Root `layouts/base.njk`, `layouts/post.njk`, `layouts/page.njk`. Isolated partials in `_includes/partials/`.
+- **Collection Filtering:** `collections.posts` and `collections.tagList` must filter through `isPostPublic(post)` (excluding `draft: true` and `hidden: true`).
+- **Sorting:** Posts sorted via `postComparator` (pinned/featured first, then chronological descending).
+- **Hidden Posts:** When `hidden: true`, page compiles to direct link but is excluded from public lists and injects `<meta name="robots" content="noindex, nofollow">`.
+
+---
+
+## 5. Obsidian Content & Frontmatter Contract
+- Required frontmatter: `title` (>= 5 chars), `date` or `created` (ISO), `tags` (array), `excerpt` (>= 20 chars).
+- Optional: `readingTime`, `draft`, `hidden`, `pinned`, `featured`.
+- Obsidian conversions: Wikilinks `[[slug|Label]]` -> `[Label](/posts/slug/)`, attachments `![[image.png]]` -> `![image](/assets/images/posts/image.png)`.
+
+---
+
+## 6. Server & Security Invariants
+- `server.js`: Native Node HTTP, zero external runtime dependencies.
+- Security headers: `X-Content-Type-Options: nosniff`, `X-Frame-Options: DENY`, `Referrer-Policy: strict-origin-when-cross-origin`.
+- Path traversal defense: Sanitize and verify paths remain inside root.
+- Healthcheck: `/healthz` returns 200 OK JSON `{ status: "ok", uptime: ... }`.
+
+---
+
+## 7. Defensive Programming & Error Prevention
+- Guard against `null`, `undefined`, primitives in all utility functions.
+- Docker: `node:22-alpine`, non-root / clean entrypoint script as PID 1.

+# Technical Blog Project Standards & Architectural Specification
+
+This document defines the authoritative engineering, design, templating, and security standards for this technical publication codebase. All new implementations, pull requests, refactors, and debugging tasks must conform to these rules.
+
+---
+
+## 1. User Content Sovereignty (Highest Priority)
+
+1. **User Edits Are Absolute Ground Truth:**
+   - The user's custom writing, post titles, tags, navigation labels, terminology, and naming choices strictly supersede any boilerplate, skill instructions, or sample mockups (`sample-designs/*`).
+2. **No Unsolicited Modifications:**
+   - Never overwrite, sanitize away, or rename user-authored text without explicit instruction.
+3. **Mandatory Clarification Gate:**
+   - Inconsistencies or typos in user writing must be flagged for clarification rather than unilaterally changed.

+   - Never implement or modify production code prior to establishing tests.
+2. **Mandatory Adversarial Testing:**
+   - Every functional implementation must include adversarial tests designed to actively falsify assumptions:
+     - Missing or malformed configuration (e.g., unset `SITE_DOMAIN` must throw).
+     - Corrupt or unexpected inputs (empty strings, `null`, `undefined`, unexpected types, HTML injections, path traversals, giant payloads).
+     - Boundary values and edge cases.
+     - Design rule violation assertions (0 instances of forbidden CSS patterns).
+     - Link and anchor integrity checks.
+3. **Pre-Presentation Verification Gate:**
+   - Before presenting the final output to the user, run `npm test`.
+   - All test cases must pass before presenting the final output. Delivering unverified or failing code is strictly forbidden.
+
+---
+
+## 3. Design System & CSS Specification
+
+Strict adherence to `sample-designs/design-specification.md` is mandatory.
+
+### 3.1 Color Palette & Token Variables
+All colors must use standard CSS custom properties defined in `src/assets/css/tokens.css`:
+- Canvas: `var(--bg-canvas)` (`#0d0f12`)
+- Surface: `var(--bg-surface)` (`#121417`)
+- Elevated: `var(--bg-elevated)` (`#1c1f26`)
+- Borders: `var(--border-color)` (`#2b303b`)
+- Text: `var(--text-primary)` (`#e0e6f0`), `var(--text-muted)` (`#8a95a5`)
+- Accents: `var(--accent-cyan)` (`#00f0ff`), `var(--accent-green)` (`#00e676`), `var(--accent-amber)` (`#ffb700`), `var(--accent-red)` (`#ff5252`)
+
+### 3.2 Hard Anti-Patterns (Forbidden)
+- **NO Glassmorphism:** Never use `backdrop-filter: blur(...)`.
+- **NO Drop Shadows or Glows:** `box-shadow: none;` and `text-shadow: none;` only.
+- **NO Gradients:** Never use `linear-gradient`, `radial-gradient`, or `conic-gradient`. Flat solid surfaces only.
+- **NO Rounded Bubbles:** `border-radius` is strictly capped between `0px` and `4px` maximum.
+- **NO Floaty / Delayed Transitions:** Hover and state transitions must be instant binary snaps (`transition: none;` or `transition: 0s;`).
+
+### 3.3 Typography & Modularity
+- UI & Code: `IBM Plex Mono`, `JetBrains Mono`.
+- Body Prose: `Inter`.
+- CSS Modularity: Zero monolithic inline `<style>` tags in HTML. Decompose styles into `tokens.css`, `reset.css`, `layout.css`, and `components/*.css`.
+
+---
+
+## 4. Templating & Eleventy Architecture
+
+1. **Layout Inheritance (Nunjucks):**
+   - Root layout: `src/_includes/layouts/base.njk`.
+   - Post layout: `src/_includes/layouts/post.njk`.
+   - Page layout: `src/_includes/layouts/page.njk`.
+   - Modular reusable partials in `src/_includes/partials/` (`global-bar.njk`, `hero-tile.njk`, `post-card.njk`, `stats-sidebar.njk`, `code-box.njk`, `footer.njk`).
+2. **Collection Invariants:**
+   - `collections.posts`: Must filter through `isPostPublic(post)` (excluding both `draft: true` and `hidden: true`) and sort using `postComparator` (prioritizing pinned/featured posts, then chronological descending).
+   - `collections.tagList`: Must filter through `isPostPublic(post)` so draft or unlisted tags never leak into public category filters.
+3. **Hidden / Unlisted Post Contract:**
+   - When frontmatter specifies `hidden: true`:
+     - Excluded from public lists, indices, and tag aggregates.
+     - Static page STILL compiles to `/posts/<slug>/index.html` and is accessible via direct URL.
+     - Emits `<meta name="robots" content="noindex, nofollow">` in `<head>` to prevent search indexing.
+
+---
+
+## 5. Obsidian Content & Frontmatter Contract
+
+1. **Frontmatter Schema:**
+   ```yaml
+   title: "Article Title"          # Required: string (>= 5 chars)
+   date: 2026-09-23                 # Required: ISO YYYY-MM-DD (or 'created')
+   tags: ["#tag1", "#tag2"]        # Required: non-empty YAML array
+   excerpt: "Article summary..."   # Required: string (>= 20 chars)
+   readingTime: "5 MIN READ"        # Optional: explicit override
+   draft: false                    # Optional: boolean
+   hidden: false                   # Optional: boolean (share by link only)
+   pinned: false                   # Optional: boolean (prioritized to top)
+   featured: false                 # Optional: boolean (featured pillar)
+   ```
+2. **Obsidian Syntax Normalization:**
+   - Wikilinks: `[[target-slug|Custom Label]]` $\rightarrow$ `[Custom Label](/posts/target-slug/)`.
+   - Wikilinks simple: `[[target-slug]]` $\rightarrow$ `[target-slug](/posts/target-slug/)`.
+   - Attachments: `![[image.png]]` $\rightarrow$ `![image](/assets/images/posts/image.png)`.
+   - Terminal alert callouts for `> [!NOTE]`, `> [!WARNING]`, etc.
+
+---
+
+## 6. Server & Security Invariants
+
+1. **Native Runtime:**
+   - `server.js` uses native Node standard library (`node:http`, `node:fs`, `node:path`) with zero external runtime dependencies.
+2. **Security Headers on All Responses:**
+   - `X-Content-Type-Options: nosniff`
+   - `X-Frame-Options: DENY`
+   - `Referrer-Policy: strict-origin-when-cross-origin`
+3. **Path Traversal Defense:**
+   - Sanitize all requested file paths using `path.resolve` and verify the resolved path remains rooted inside the target directory. Block `..` and malicious slug sequences.
+4. **Healthcheck Telemetry:**
+   - `/healthz` and `/health` must respond with HTTP 200 JSON `{ status: "ok", uptime: <seconds> }`.
+
+---
+
+## 7. Defensive Programming & Error Prevention
+
+1. **Input Guarding:**
+   - Never assume incoming arguments have expected shape. Always guard against `null`, `undefined`, non-objects, and primitive inputs (e.g., `item.data ?? item`).
+2. **Clean Container Contracts:**
+   - Container images must use `node:22-alpine`.
+   - Dynamic entrypoint (`entrypoint.sh`) must build markdown on boot, handle optional watcher (`WATCH=true`), and execute server as PID 1 (`exec node server.js`).

 ### 2.4 Strict Test-Driven Development (TDD) & Adversarial Verification Mandate
-- **Test-First Development:** For all new features, custom filters, template helpers, frontmatter schemas, or configuration changes, write automated tests asserting expected behaviors and edge cases *before* or alongside implementing the code.
+- **Strict Test-First Invariant (Tests Before Code):**
-- **Adversarial Mindset:** Actively design tests to break assumptions:
+  - Test cases MUST ALWAYS be written and established *before writing or modifying any functional code* (filters, templates, server routes, ingestion logic, build scripts).
-  - Missing environment variables (e.g. unset `SITE_DOMAIN` must throw).
+  - Never write or modify functional or production code before the corresponding automated tests are created.
-  - Malformed frontmatter (missing titles, invalid dates, empty tags).
+- **Mandatory Adversarial Testing:**
-  - Edge-case inputs to filters (empty strings, giant numbers, special characters).
+  - Standard behavior for any functional change MUST ALWAYS include adversarial testing specifically designed to falsify assumptions and break the implementation:
-  - Design rule violations (asserting 0 instances of `backdrop-filter`, `box-shadow`, gradients, or floaty animations).
+    - Missing or malformed environment variables (e.g., unset `SITE_DOMAIN` must throw).
-  - Broken internal links and missing anchor tags in generated HTML.
+    - Malformed frontmatter (missing required keys, invalid dates, malformed tags, extra/empty fields).
-- **Verification Gate:** Every code change must be verified by running `npm test`. No feature or commit is considered complete unless 100% of the test suite passes.
+    - Edge-case and malicious inputs to filters and functions (empty strings, undefined/null values, unexpected types, HTML injections, path traversals, giant payloads).
+    - Design rule violations (asserting 0 instances of `backdrop-filter`, `box-shadow`, gradients, or floaty animations).
+    - Broken internal links, missing assets, and broken TOC anchor tags.

+### 2.3 Development Standards: Strict TDD & Adversarial Verification
+This project enforces a strict test-first development lifecycle and verification standard:
+1. **Tests Written Before Functional Code:** Automated test cases in `test/` must always be written before writing or modifying any functional code, filters, templates, server endpoints, or scripts.
+2. **Mandatory Adversarial Testing:** Standard behavior for any functional change must always include adversarial test cases (boundary values, malformed/null inputs, unauthorized requests, path traversals, corrupt frontmatter, and design spec violations).
+3. **Pre-Presentation Verification Gate:** Every change must be verified by running `npm test`. All test cases must pass before presenting the final output or committing code.
