Replaces silent error-suppressed @file_get_contents('/proc/...') calls with an explicit is_proc_readable() check that respects open_basedir restrictions. This eliminates suppressed errors and avoids undefined behavior when PHP runs with restricted filesystem access.

Core changes:

1. Monitor module (admin/modules/monitor.php):

2. Added is_proc_readable(string \$path): bool helper function

   • Validates path starts with /proc/
   • Checks against open_basedir entries if set
   • Returns is_readable() result only when access is permitted

3. Replaced @file_get_contents('/proc/meminfo') with guarded call

   • Suppressor removed; function handles restriction transparently
4. Replaced @file_get_contents('/proc/net/dev') with guarded call
5. Replaced @file_get_contents('/proc/uptime') with guarded call

6. Added missing ':' presence check before explode() in meminfo parser

   • Prevents "Undefined offset" warnings on empty/malformed lines

Benefits:

• Eliminates error suppression antipattern for /proc reads
• Correct behavior under open_basedir=restricted environments
• Prevents PHP warnings from malformed /proc/meminfo lines

Technical notes:

• open_basedir path separator is PATH_SEPARATOR (OS-aware)
• Fallback: if open_basedir is empty, only is_readable() is checked

Align documentation, static analysis config, and tests with the renamed config files and the \$afile variable that replaced \$aroute.

Core changes:

1. CONTRIBUTING.md / UPGRADING.md:
2. Replace all \$aroute references with \$afile (current variable name)
3. .gitignore:
4. Remove /config/lang.php exclusion (lang config is now tracked)
5. phpstan.neon:
6. Remove outdated ignore rule for config/config_uploads.php path
7. templates/index.html:
8. Update meta-refresh URL: http://www.slaed.net -> https://slaed.net
9. tests/ConfigValidationTest.php:
10. Rename camelCase properties/methods to snake_case (\$basePath -> \$base_path)

11. Update scanConfigFiles -> scanconfig_files; testRequiredConfigFilesExist -> testRequiredconfig_filesExist (PSR-consistent project style)

12. config/security.php / config/users.php:
13. Cosmetic alignment of => operators for readability

Benefits:

• Docs reflect the actual current variable name (\$afile)
• PHPStan no longer reports false positives for removed paths
• Tests use consistent naming convention with the rest of the project

Technical notes:

• No functional changes; docs, config cosmetics, and test naming only

The legacy end_chmod() helper performed chmod tests by writing a test file to config/chmod.php, which relied on a dedicated config entry and Linux-specific uname/chmod logic. It has been replaced by the modern checkPerms() function that handles permission checks uniformly.

Core changes:

1. core/admin.php:
2. Delete end_chmod() function (~20 lines) marked # DELETE OLD

3. Update fav_aliste(): replace include('config/config_media.php') with $confm = $conf['media'] ?? [] (uses global $conf)

4. admin/modules/blocks.php:

5. Replace 3 end_chmod() calls with checkPerms() equivalents: fileadd(): end_chmod('blocks/', 777) -> checkPerms('blocks/', 1) filecode(): same for directory and per-file permission check

Benefits:

• Removes OS-specific chmod probe that relied on config/chmod.php
• checkPerms() provides consistent, testable permission reporting
• Reduces dead code surface in core/admin.php

Technical notes:

• config/chmod.php remains as an empty return [] placeholder
• No user-facing behaviour change; only internal permission checking

Drop the redundant config_ prefix from all module config files, aligning naming with the unified config bootstrap introduced in core/system.php. The new names match the module names directly.

Core changes:

1. Deleted (23 files) (config/config_*.php):

2. config_auto_links, config_comments, config_contact, config_content, config_faq, config_files, config_forum, config_global, config_help, config_jokes, config_links, config_media, config_money, config_news, config_order, config_pages, config_privat, config_rewrite, config_shop, config_templ, config_users, config_voting, config_whois

3. Added (20 files) (config/*.php):

4. auto_links, contact, content, faq, files, forum, help, jokes, lang, links, media, money, news, order, pages, privat, rewrite, shop, voting, whois

Benefits:

• Simpler, predictable naming: config/{module}.php
• Eliminates the inconsistent config_ prefix across all modules
• lang.php added as a new first-class config file

Technical notes:

• Git detected renames automatically (rename detection enabled)

• config_global, config_templ, config_users, config_comments removed (merged into global config or no longer needed as separate files)

Replace the deprecated \$prefix variable in all SQL snippets shown in project documentation with the PREFIX_DB constant, keeping examples consistent with the actual codebase after the refactor.

Core changes:

1. README.md:
2. SQL example: '.\$prefix.'_users → '.PREFIX_DB.'_users
3. CONTRIBUTING.md (2 occurrences):
4. SQL examples in "Correct - Safe" and function sample updated
5. SECURITY.md:
6. Prepared-statement example updated
7. UPGRADING.md:
8. Migration guide example for 6.3.x updated

Benefits:

• Documentation reflects current coding standard
• New contributors see the correct pattern from the start

Technical notes:

• No functional code changed; documentation only
