Improve site-check quality: fix broken site configs, add diagnostic utilities, and make self-check report-only by default with opt-in auto-disable. (#2301)

- Fix VK and TradingView checkType; add Reddit and Microsoft Learn API-style probes where appropriate; adjust or disable entries that are unreliable under anti-bot protection.
- Self-check: stop aggressive auto-disable; default to reporting issues only; add --auto-disable and --diagnose for optional fixes and deeper output.
- Tooling: add utils/site_check.py and utils/check_top_n.py (and related helpers) to inspect and rank site behavior against the top-N list
- Scope: aligns with fixing top-traffic / high-impact sites and making diagnostics repeatable without silently flipping disabled flags

+## 6. Development utilities
+
+### 6.1 `utils/site_check.py` — Single site diagnostics
+
+A comprehensive utility for testing individual sites with multiple modes:
+
+```bash
+# Basic comparison of claimed vs unclaimed (aiohttp)
+python utils/site_check.py --site "VK" --check-claimed
+
+# Test via Maigret's checker directly
+python utils/site_check.py --site "VK" --maigret
+
+# Compare aiohttp vs Maigret results (find discrepancies)
+python utils/site_check.py --site "VK" --compare-methods
+
+# Full diagnosis with recommendations
+python utils/site_check.py --site "VK" --diagnose
+
+# Test with custom URL
+python utils/site_check.py --url "https://example.com/{username}" --compare user1 user2
+
+# Find a valid username for a site
+python utils/site_check.py --site "VK" --find-user
+```
+
+**Key features:**
+- `--maigret` — Uses Maigret's actual checking code, not raw aiohttp
+- `--compare-methods` — Shows if aiohttp and Maigret see different results (useful for debugging)
+- `--diagnose` — Validates checkType against actual responses, suggests fixes
+- Color output with markers detection (captcha, cloudflare, login, etc.)
+- `--json` flag for machine-readable output
+
+**When to use each mode:**
+
+| Mode | Use case |
+|------|----------|
+| `--check-claimed` | Quick sanity check: do claimed/unclaimed still differ? |
+| `--maigret` | Verify Maigret's actual behavior matches expectations |
+| `--compare-methods` | Debug "works in curl but fails in Maigret" issues |
+| `--diagnose` | Full analysis when a site is broken, get fix recommendations |
+
+### 6.2 `utils/check_top_n.py` — Mass site checking
+
+Batch-check top N sites by Alexa rank with categorized reporting:
+
+```bash
+# Check top 100 sites
+python utils/check_top_n.py --top 100
+
+# Faster with more parallelism
+python utils/check_top_n.py --top 100 --parallel 10
+
+# Output JSON report
+python utils/check_top_n.py --top 100 --output report.json
+
+# Only show broken sites
+python utils/check_top_n.py --top 100 --only-broken
+```
+
+**Output categories:**
+- `working` — Site check passes
+- `broken` — Check fails (wrong status, missing markers)
+- `timeout` — Request timed out
+- `anti_bot` — 403/429 or captcha detected
+- `error` — Connection or other errors
+- `disabled` — Already disabled in data.json
+
+**Report includes:**
+- Summary counts by category
+- List of broken sites with issues
+- Recommendations for fixes (e.g., "Switch to checkType: status_code")
+
+### 6.3 Self-check behavior (`--self-check`)
+
+The self-check command has been improved to be less aggressive:
+
+```bash
+# Check sites WITHOUT auto-disabling (default)
+maigret --self-check --site "VK"
+
+# Auto-disable failing sites (old behavior)
+maigret --self-check --site "VK" --auto-disable
+
+# Show detailed diagnosis for each failure
+maigret --self-check --site "VK" --diagnose
+```
+
+**Behavior changes:**
+
+| Flag | Effect |
+|------|--------|
+| `--self-check` alone | Reports issues but does NOT disable sites |
+| `--auto-disable` | Automatically disables sites that fail (opt-in) |
+| `--diagnose` | Prints detailed diagnosis with recommendations |
+
+**Why this matters:**
+- Old behavior was too aggressive — sites got disabled without explanation
+- New behavior reports issues and suggests fixes
+- Explicit `--auto-disable` required to modify database
+

+
+## 7. Lessons learned (practical observations)
+
+Collected from hands-on work fixing top-ranked sites (Reddit, Wikipedia, Microsoft Learn, Baidu, etc.).
+
+### 7.1 JSON API is the first thing to look for
+
+Both Reddit and Microsoft Learn had working public APIs that solved the problem entirely. The web pages were SPAs or blocked by anti-bot measures, but the APIs worked reliably:
+
+- **Reddit**: `https://api.reddit.com/user/{username}/about` — returns JSON with user data or `{"message": "Not Found", "error": 404}`.
+- **Microsoft Learn**: `https://learn.microsoft.com/api/profiles/{username}` — returns JSON with `userName` field or HTTP 404.
+
+This confirms the playbook recommendation: always check for `/api/`, `.json`, GraphQL endpoints before giving up on a site.
+
+### 7.2 `urlProbe` is a powerful tool
+
+It separates "what we check" (API) from "what we show the user" (human-readable profile URL). Reddit is a perfect example:
+
+```json
+{
+  "url": "https://www.reddit.com/user/{username}",
+  "urlProbe": "https://api.reddit.com/user/{username}/about",
+  "checkType": "message",
+  "presenseStrs": ["\"name\":"],
+  "absenceStrs": ["Not Found"]
+}
+```
+
+The check hits the API, but reports display `www.reddit.com/user/blue`.
+
+### 7.3 aiohttp ≠ curl ≠ requests
+
+Wikipedia returned HTTP 200 for `curl` and Python `requests`, but HTTP 403 for `aiohttp`. This is **TLS fingerprinting** — the server identifies the HTTP library by cryptographic characteristics of the TLS handshake, not by headers.
+
+**Key insight:** Changing `User-Agent` does **not** help against TLS fingerprinting. Always test with aiohttp directly (or via Maigret with `-vvv` and `debug.log`), not just `curl`.
+
+```python
+# This returns 403 for Wikipedia even with browser UA:
+async with aiohttp.ClientSession() as session:
+    async with session.get(url, headers={"User-Agent": "Mozilla/5.0 ..."}) as resp:
+        print(resp.status)  # 403
+```
+
+### 7.4 HTTP 403 in Maigret can mean different things
+
+Initially it seemed Wikipedia was returning 403, but `curl` showed 200. Only `debug.log` revealed the real picture — aiohttp was getting blocked at TLS level.
+
+**Lesson:** Use `-vvv` flag and inspect `debug.log` for raw response status and body. The warning message alone may be misleading.
+
+### 7.5 Dead services migrate, not disappear
+
+MSDN Social and TechNet profiles redirected to Microsoft Learn. Instead of deleting old entries:
+
+1. Keep old entries with `disabled: true` as historical record.
+2. Create a new entry for the current service with working API.
+
+This preserves audit trail and avoids breaking existing workflows.
+
+### 7.6 `status_code` is more reliable than `message` for APIs
+
+Microsoft Learn API returns HTTP 404 for non-existent users — a clean signal without HTML parsing. For JSON APIs that return proper HTTP status codes, `status_code` is often the best choice:
+
+```json
+{
+  "checkType": "status_code",
+  "urlProbe": "https://learn.microsoft.com/api/profiles/{username}"
+}
+```
+
+No need for fragile string matching when the API speaks HTTP correctly.
+
+### 7.7 The playbook classification works
+
+The decision tree from the documentation accurately describes real-world cases:
+
+| Situation | Playbook says | Actual result |
+|-----------|---------------|---------------|
+| Captcha (Baidu) | `disabled: true` | Correct |
+| TLS fingerprinting (Wikipedia) | `disabled: true` (anti-bot) | Correct |
+| Working API available (Reddit, MS Learn) | Use `urlProbe` | Correct |
+| Service migrated (MSDN → MS Learn) | Update URL or create new entry | Correct |
