Gmer4Lfe dfe4c0d495 Toggle the script in the orchestrator you clicked, not the first one that lists it
docker_update.sh runs bare in daily, --weekly in weekly and --remainder in
monthly, so switching it off in monthly disabled the daily run and reported
success.

// ═══════════════════════════════════════════════════════════════════════════════════════════════
// PURPOSE
// Orchestrator membership toggle. Comments or uncomments one script's entry inside the
// *_SCRIPTS arrays in master.conf, so the scheduler page can take a script out of an
// orchestrator's run list without deleting it.
//
// OPERATIONAL MODEL
// This is not the same switch as the scheduler's enable/disable. Scheduler state controls
// whether a *cron entry* fires; this controls whether an orchestrator *calls a child
// script* during its own run. A script can be disabled here and still run, if another
// orchestrator lists it — unraid_api_key_renew.sh is deliberately in two arrays.
//
// The edit is a comment marker, not a deletion. The line stays in master.conf with its
// arguments and its position intact, so re-enabling restores exactly what was there before
// and a diff shows an intent change rather than a removal.
//
// DESIGN PRINCIPLES
// Only the first match is toggled.
// vv_conf_toggle_script() breaks after the first array entry it matches. A script
// listed in two orchestrators is not silently changed in both by one click.
//
// No match is success, not failure.
// A script that is not in any array has nothing to toggle and the conf is already in
// the requested state. Returning an error there would make the UI report a problem
// where none exists.
//
// OPERATIONAL SAFEGUARDS
// POST only, checked before any parameter is read.
//
// The id is pattern-matched and traversal-checked separately.
// ^[a-zA-Z0-9_./\-]+\.sh$ permits the Category/script.sh form the arrays actually use,
// so the slash cannot simply be banned — str_contains($id, '..') is therefore a second,
// explicit check rather than something folded into the pattern.
//
// The id is never used as a path.
// It reaches vv_conf_toggle_script() only as a preg_quote()d needle matched against
// existing lines in master.conf. Nothing is opened, executed, or created from it, so a
// value that slipped past validation still has no file to reach.
//
// The scope of the edit is bounded to array bodies.
// The library tracks whether it is inside a `*_SCRIPTS=(` block and skips every line
// outside one, so a matching string in a comment or an unrelated variable cannot be
// rewritten.
//
// The write is atomic, backed up, verified and logged.
// vv_conf_toggle_script() goes through vv_conf_edit(), the one guarded conf write path:
// an exclusive lock, a timestamped copy into CONF_BACKUP_DIR, bash -n on the candidate,
// tmp + rename to install it, then the installed file is sourced to prove it still loads.
// There is no single key to read back for a commented array member, so a clean source is
// the whole assertion. Every script sources master.conf; a truncated or unparseable write
// here would be a system-wide outage rather than a lost toggle.
//
// A script in no array writes nothing at all.
// The rewrite returns the contents unchanged, which reports success without taking a
// backup or touching the file. "Already in the requested state" is not a write.
//
// REQUEST
// POST id=<Category/script.sh> enabled=0|1
//
// RESPONSE
// {"ok":true,"error":null}
// {"ok":false,"error":"POST only"|"Invalid id"|"Failed to write master.conf"}
//
// DEPENDS ON
// include/scheduler.php vv_conf_toggle_script() → vv_conf_edit() → vv_write_conf_raw()
// Configurations/master.conf the *_SCRIPTS arrays
