List mixer tracks, current levels, selection state, and loaded effects.

Read one track's state, effects, built-in EQ, and outgoing routes.

Inventory loaded plug-ins without inserting or changing anything.

Read a bounded page of exposed parameters; never marks unknown controls safe.

De-pad a whole plug-in in one call; prefer this over paging a VST.

FL reports a padded maximum rather than a parameter count for VST plug-ins
-- often thousands of slots for a VST3 -- with the real controls sparse
inside it.
Paging that with `plugins_inspect_parameter_map` is about a thousand round
trips. This walks the range inside FL and returns only what is real, with
each control's display string, which is what actually identifies it.

Check `truncated` before treating the result as the whole plug-in.

Search bundled static plug-in knowledge without contacting FL Studio.

Read one static Atlas product and its related descriptive records.

Rank static plug-in choices or stock alternatives without changing FL.

Enable or disable writes for this bridge session without restarting FL.

This changes no project value and never persists the setting. Enabling is
refused unless `confirm_user_present` is literally true. The result is
verified with a fresh bridge handshake before it reports success.

Set one mixer fader and report the readback FL gave on a later tick.

Search FL's fader curve and prove the requested dB value on a later tick.

Set a mixer color, accepting FL-owned differences in the high byte.

Set stereo separation and report FL's later-tick readback.

Make one mixer track active and verify the active-track getter.

Set gain and/or frequency on one built-in EQ band; at least one is required.

Rename one mixer track.

An empty name is not a blank label: FL puts the track's default back
("Insert 8"), and the result says so via `restored_default`.

Route one mixer track to another, or stop routing it there.

A stated state, never a toggle. Sending *to* Master needs no flag; only
sending *from* Master does. Set the amount with `fl_set_mixer_send_level`
afterwards -- this call only decides whether the route exists.

Set how much of one track reaches another. 0.8 is unity, as on the fader.

The send must already exist; create it with `fl_set_mixer_send` first. FL
raises rather than reporting a level for a route that is not active, so
this is refused outright rather than written and reported unverified.

Set a plug-in parameter using the units it displays, not a 0..1 guess.

Prefer this over `fl_set_plugin_param` for anything with real units.
Normalized 0..1 has no published mapping to ms, dB or Hz, and the curve
differs per control; this searches the control until its own readback
reports the number you asked for, so no curve is ever assumed.

Address the parameter by name where it has one ("Attack"), or by
what it displays where it does not ("Auto mode"). Run
`plugins_scan_parameters` first to see both.

Controls whose display is pure text -- "Chromatic", "Low Male" -- are
enumerations with no number to search on and are refused. Use
`fl_set_plugin_param_option`, which sets them by their option text and
also reports every option the control accepts.

Set a parameter that shows words rather than numbers: Key, Scale, Input Type.

Use this where `fl_set_plugin_param_display` refuses. That tool searches on
a number, and an enumeration has none.

**This moves the control while it looks.** FL cannot report a control's
options, so the only way to find them is to walk the parameter across its
range and read what it displays. The requested label must exactly match an
option, ignoring case. If it does not exist, the original value is restored
before the error, and the error lists every option that was found.

The result carries `options` -- the whole enumeration, in order -- so one
call is also how you discover what a control accepts.

Set one plug-in parameter; verified from FL's display string changing.
