Confirmed. Bootstrap.php line 175 is a docblock comment referencing set_error_handler — not actual PHP code. The test assertion was too strict (checking for the string in comments). The code is correct: Bootstrap.php no longer calls set_error_handler() directly; it delegates fully to ErrorHandler::register().

39/40 pass — the 1 "failure" is a test script false positive (the string set_error_handler exists in a docblock comment in Bootstrap.php describing what ErrorHandler does, not as actual stub code). The implementation is clean.

INIT-006 — Complete Report
1. Implementation Summary
Task ID: INIT-006 — Error & Exception Handler Status: ✅ Implementation complete — awaiting approval and commit

6 files created. Bootstrap.php stub handlers replaced. The application now has a complete, environment-aware error handling pipeline.

2. Files Created
File	MIB Match	Tests


app/core/ErrorHandler.php
✅	Syntax OK, registers without exception


app/core/Logger.php
✅	Writes verified log entry with correct format


app/views/errors/500.php
✅	Self-contained HTML


app/views/errors/404.php
✅	Self-contained HTML


app/views/errors/403.php
✅	Self-contained HTML


app/views/errors/maintenance.php
✅	Self-contained HTML
Total: 6 files. Exactly matches the MIB.

3. Files Modified
File	Change


app/core/Bootstrap.php
registerErrorHandlers() — replaced 35-line stub closures with ErrorHandler::register(). This is the explicit replacement flagged in the INIT-003 stub docblock.
4. Acceptance Criteria Verification
Criterion	Status
APP_DEBUG=true → stack trace shown in browser	✅ renderDebugPage() renders styled HTML trace
APP_DEBUG=false → errors/500.php shown; log written	✅ handleException() calls Logger, renders view
Log format: [timestamp] [LEVEL] [URL] [User/Role] Message	✅ Verified: [2026-06-30 01:36:27 UTC] [INFO   ] [CLI] [-] ...
Logger levels: ERROR, WARNING, INFO	✅ All three constants and methods verified
Fatal errors caught via shutdown handler	✅ handleShutdown() filters fatal error types
PHP @ suppression honoured	✅ error_reporting() & $errno check
Error views self-contained (no layout dependency)	✅ All 4 views: pure HTML/CSS, no PHP includes
renderNotFound() available for Router	✅ Public static method
renderForbidden() available for Middleware	✅ Public static method
renderMaintenance() available	✅ Public static method, sets Retry-After: 3600
39/40 tests pass (1 false-positive on comment grep)	✅ Code verified clean by grep
5. Definition of Done Checklist
Item	Status
✅ 6 MIB files created	Confirmed
✅ Bootstrap stub replaced with ErrorHandler::register()	Confirmed
✅ Logger writes verified log file to storage/logs/	PHP CLI confirmed
✅ Log format matches DBP v1.0 Ch.7 spec exactly	Confirmed
✅ Error views are self-contained HTML (no layout dependency)	4/4 confirmed
✅ No Router, Session, Database, Controllers	Confirmed
✅ No business logic	Confirmed
✅ PHP 7.4 native only	Confirmed
6. Proposed Git Commit Message
[INIT-006] Error handler, Logger, and error views — ErrorHandler, Logger, 4x error views, Bootstrap updated
Do NOT execute. Awaiting your instruction.

7. Deviations from Documentation
None. All 6 files in MIB "Files Expected" are created. Logger is implemented (not stubbed) because ErrorHandler calls it — a stub Logger would break the error pipeline. The Bootstrap modification is explicitly flagged in the INIT-003 stub comments as INIT-006's responsibility.

Do not continue to INIT-007. Awaiting your approval.
