Overview of Changes

This PR closes PROJ-1 by finalizing PHP 8.5 runtime baseline stability with verified QA and deploy evidence.

Implemented fixes:

• Added idempotent migration to ensure legacy user_logs table exists:
  • db/migrate/20260218221000_ensure_user_logs_table_exists.php
• Synced canonical schema/state artifacts:
  • db/schema.sql
  • db/table_schema/production/user_logs.php
• Hardened tag subscription user partial to avoid PHP 8.5 warning-to-exception failures in account edit flow:
  • app/views/tag_subscription/_user_listing.php

QA / Verification

• composer run ci:lint: pass
• composer run test: pass (15 tests / 72 assertions)
• composer run analyse: pass (project script skipped: no phpstan config)
• composer run cs-check: pass (project script skipped: no php-cs-fixer config)
• composer run assets:verify: pass
• Manual checks (VPS):
  • GET / -> 200
  • GET /post -> 200
  • GET /post/show/1 -> 404 (expected on empty dataset; no fatal)
  • GET /help -> 200
  • GET /static/more -> 200
  • GET /user/login -> 200
  • GET /user/edit anonymous -> 302
  • POST /user/authenticate (qa user) -> 302
  • GET /user/edit authenticated -> 200
  • Log delta scan: no new fatal/parse/class-not-found warnings in smoke scope
  • Schema check: user_logs table + FK fk_user_logs__user_id present

Deployment Impact

• No deploy impact
• Requires deploy runbook update
• Requires environment/config changes
• Requires migration
• Rollback notes:
  • Revert app commit and deploy previous release.
  • Migration is additive and backward-compatible; rollback can keep user_logs table.

Reviewer Focus

• Migration idempotency and FK creation safety in mixed environments.
• Partial fix in app/views/tag_subscription/_user_listing.php under PHP 8.5 warning/error behavior.
• Consistency between migration, schema, and table schema cache artifacts.

Checklist

• Scope matches linked PROJ / issue
• No secrets or credentials committed
• Docs updated where needed
• Backward compatibility considered
• Ready to merge

Pull request overview

This PR finalizes the PHP 8.5 runtime baseline by adding an idempotent migration for the user_logs table, syncing canonical schema artifacts, and hardening a view partial to prevent PHP 8.5 warnings in the account edit flow. The changes address infrastructure gaps and PHP 8.5 compatibility issues discovered during deployment verification.

Changes:

• Added idempotent migration to ensure user_logs table exists with proper foreign key constraints
• Synced canonical schema artifacts (schema.sql and table_schema cache)
• Hardened tag subscription user listing partial with defensive null checks
