README documented ErrorHandler.php as a "global error/exception
handler", but ErrorHandler::init() had exactly one caller app-wide
(api/get_template.php). 13 endpoints never called
ini_set('display_errors', 0) at all, relying on the server's global
php.ini default, and index.php never registered any handler — a
genuine PHP fatal during a page render fell through to PHP's raw
default handling with no app-level 500 response, styled or otherwise.
Investigating the "13 endpoints" claim turned up that 9 of them
(assign_ticket.php, audit_log.php, check_duplicates.php,
get_comments.php, get_users.php, notifications.php, saved_filters.php,
user_preferences.php, watch_ticket.php) already require
api/bootstrap.php as their first statement, which itself calls
ini_set('display_errors', 0) — so they were never actually exposed;
the static grep just couldn't see through the require. The 3 that
were genuinely unprotected (bulk_operation.php, download_attachment.php,
health.php) are fixed here. ticket_dependencies.php already has its
own complete hand-rolled equivalent (shutdown handler, error handler,
exception handler, output-buffer aware) and was deliberately left
alone rather than risk double-registering handlers.
Rather than duplicate the fix 30+ times, wired ErrorHandler::init()
directly into api/bootstrap.php (covering all 9 files above at once)
and into each of the other endpoints' own ini_set/error_reporting
pair, replacing it in place — additive only: existing try/catch blocks
in every endpoint still handle what they already handled identically,
this only adds a safety net for genuinely uncaught fatals that fell
through everything else. Before doing this app-wide, removed
ErrorHandler::init()'s override of PHP's 'error_log' ini setting: it
redirected every error_log() call in the request to a fixed /tmp file,
which would have silently diverted logs away from wherever the server
is actually configured to send them the moment this got wired into
more than one endpoint. That override only existed to support
getRecentErrors(), which has zero callers app-wide.
For index.php (page views, not JSON), added an 'html' response mode to
ErrorHandler that renders a new views/error_500.php instead of a JSON
body. That view is deliberately self-contained (no layout_header.php,
no $GLOBALS/session/DB dependency) since a genuine fatal can happen
before config.php finishes loading or mid-session-start.
Verified: a real uncaught error with no prior output correctly
produces a clean JSON 500 (API mode) or the styled HTML page (page
mode) to the client while the full stack trace goes to error_log, not
the response; normal (non-fatal) requests through both a
bootstrap.php-based endpoint and index.php are byte-for-byte
unaffected. Full project phpcs pass is clean.

api/bootstrap.php's centralized CSRF handling echoes
CsrfMiddleware::getToken() on a 403 rejection specifically so
lt.api's client-side resync (assets/js/base.js) can recover once
window.CSRF_TOKEN goes stale (token expiry, or a write in another tab
rotating the shared session-scoped token). 12 endpoints duplicate
CsrfMiddleware::validateToken() inline instead of routing through
bootstrap.php, and their 403 body omitted csrf_token entirely —
custom_fields.php, clone_ticket.php, delete_comment.php,
delete_attachment.php, bulk_operation.php, generate_api_key.php,
manage_templates.php, manage_recurring.php, revoke_api_key.php,
manage_workflows.php, ticket_dependencies.php, and
upload_attachment.php.
Once a client's token drifted out of sync, the next write to any of
these 12 endpoints returned a 403 with no way to self-heal — every
subsequent write to any endpoint kept failing until a manual reload,
since the resync mechanism was only wired up on a minority of the
app's write surface. Took the minimal fix the issue names as
sufficient (add 'csrf_token' => CsrfMiddleware::getToken() to each
rejection body) rather than restructuring all 12 through bootstrap.php,
to avoid behavioral risk from rewiring each endpoint's differing
auth/bootstrapping. generate_api_key.php and revoke_api_key.php threw
a generic Exception for this case (swallowed into a plain error-message
response with no room for extra fields), so those two now short-circuit
with a direct JSON response instead, matching the other 10.
Verified end-to-end against real running endpoints with a real
session and real MariaDB: sent a wrong CSRF token to one endpoint of
each response shape (plain json_encode, ResponseHelper::error, and the
formerly exception-based path) and confirmed all three now return the
current valid csrf_token in the 403 body.

- ticket_dependencies.php: pass current user id/groups/is_admin into the
visibility-filtered DependencyModel methods; drop (int) casts that
stripped leading zeros from varchar ticket_ids
- update_ticket.php: authorize visibility changes (admin or creator only);
enforce requires_comment transitions server-side (400 + requires_comment
flag so the client can prompt-and-retry); return proper 401/400/403
- add_comment.php: take commenter name from the session not the client
(anti-spoofing); validate parent_comment_id belongs to the ticket;
reject empty comments; pass ticket visibility to notifications so
non-public comment bodies aren't leaked
- add_comment/update_comment/bulk_operation: validate CSRF for all
state-changing methods, not just POST
- bootstrap.php: return the current CSRF token on rejection and never
rotate it on a rejected request, so a desynced client can auto-recover
- correct auth->401 and validation->400 status codes across these endpoints

- TicketModel::getAllTickets() now accepts optional $user param and applies
getVisibilityFilter() so non-admin users cannot see internal/confidential
tickets they lack access to from the dashboard listing
- DashboardController passes $GLOBALS['currentUser'] to getAllTickets()
- clone_ticket.php: move Content-Type header to top so all error paths send
correct JSON content type
- AuthMiddleware: filter group names from HTTP header to [a-z0-9_-] only,
preventing header injection via malformed group names
- add_comment.php: return HTTP 201 on success, 500 in catch block
- update_comment.php, delete_comment.php: return 500 in catch blocks

Security:
- Fix IDOR in delete/update comment (add ticket visibility check)
- XSS defense-in-depth in DashboardView active filters
- Replace innerHTML with DOM construction in toast.js
- Remove redundant real_escape_string in check_duplicates
- Add rate limiting to get_template, download_attachment, audit_log,
saved_filters, user_preferences endpoints
Bug fixes:
- Session timeout now reads from config instead of hardcoded 18000
- TicketController uses $GLOBALS['config'] instead of duplicate .env parsing
- Add DISCORD_WEBHOOK_URL to centralized config
- Cleanup script uses hashmap for O(1) ticket ID lookups
Dead code removal (~100 lines):
- Remove dead getTicketComments() from TicketModel (wrong bind_param type)
- Remove dead getCategories()/getTypes() from DashboardController
- Remove ~80 lines dead Discord webhook code from update_ticket API
Consolidation:
- Create api/bootstrap.php for shared API setup (auth, CSRF, rate limit)
- Convert 6 API endpoints to use bootstrap
- Extract escapeHtml/getTicketIdFromUrl into shared utils.js
- Batch save for user preferences (1 request instead of 7)
