Systemic CI failure: PHP 8.5 (2 events)

[superdav42]

Summary

• Pattern: PHP 8.5
• Error signature: no_failed_log_output
• Scope: this repo
• Events observed: 2
• Systemic threshold: 2

Resolution

The default branch now contains the focused SSO test repair in merged PR #1749 (f4e9ab38). Its complete PHP 8.2–8.5 matrix passed, including PHP 8.5. No duplicate PR is required.

Why this looks systemic

• The same check/signature failed repeatedly within the notification window.
• This suggests a shared workflow/tooling defect rather than a PR-specific code problem.

Evidence

• pr:fix: isolate settings cache by network #1745 (failure) - PHP 8.5 failed in the PHPUnit step.
• pr:fix: avoid caching transient database misses #1744 (failure) - PHP 8.5 failed in the PHPUnit step.
• The same terminal failures reproduce on the default-branch workflow in PHP 8.2, 8.4, and 8.5: SSO_Coverage_Test::test_startup_loads_domain_mapping_redirect_host_filter and SSO_Extended_Test::test_get_setting_returns_true_for_enable_sso.

Root Cause

The PHP 8.5 label is incidental. The SSO default was changed to disabled in #1741, leaving two tests with shared-state and enabled-by-default assumptions. Commit d7ba3b7f on open PR #1724 isolates the relevant settings and redirect hooks; its PHP 8.2–8.5 checks passed.

Worker Guidance

Goal

Restore a passing PHP test matrix by applying the existing isolated SSO test fix without changing production behavior or CI matrix configuration.

Files Scope

• tests/WP_Ultimo/SSO/SSO_Coverage_Test.php
• tests/WP_Ultimo/SSO/SSO_Extended_Test.php

Files to inspect first

1. tests/WP_Ultimo/SSO/SSO_Coverage_Test.php — isolate redirect-host filters and the Domain Mapping singleton in the mapped-domain startup test.
2. tests/WP_Ultimo/SSO/SSO_Extended_Test.php — assert an explicitly filtered enable_sso value rather than assuming the default is enabled.
3. inc/sso/class-sso.php — confirm the production default is intentionally disabled and must remain unchanged.

Implementation steps

1. Reuse the focused test-only changes from d7ba3b7f rather than recreating them.
2. Remove only filters introduced by each test and restore mutated singleton/request state in finally blocks.
3. Replace the stale default-enabled assertion with an explicit wu_get_setting filter.
4. Do not alter production SSO code, test configuration, or workflow files.

Verification

• vendor/bin/phpunit --filter 'SSO_Coverage_Test|SSO_Extended_Test'
• Run vendor/bin/phpcs tests/WP_Ultimo/SSO/SSO_Coverage_Test.php tests/WP_Ultimo/SSO/SSO_Extended_Test.php when Composer dependencies are available.

Runtime testing

No browser or live WordPress runtime testing is expected. The focused WordPress PHPUnit tests exercise the affected startup hooks and settings behavior. Full CI validates PHP 8.2–8.5 after the PR is created.

Brief recovery

Brief recovery was attempted on 2026-09-01. The original signature lacked failed-log detail; direct job inspection identified the two SSO tests and a validated salvage commit.
