Merge Risk: 🟠 High · up to This PR adds Web Audio Modules support, letting users load third-party audio plugins by URL. A previously raised concern that loading an untrusted or attacker-supplied plugin URL could run arbitrary code in the application has not been confirmed fixed. A minor GUI-sizing inconsistency in an unrelated file and a possible aspect-ratio distortion in the WAM GUI scaling also remain unconfirmed. Separately, the change unintentionally removes the existing 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Inline comments:
In `@ui/src/objects/wam`~/wam-community-plugins.ts:
- Around line 43-46: Update parseWamCommunityPlugins to resolve registry URLs
through a safe helper that catches invalid URL construction. Skip entries when
path resolution fails, while treating invalid thumbnail values as absent without
aborting valid plugin parsing; preserve URL resolution against
WAM_COMMUNITY_PLUGIN_BASE_URL.
In `@ui/src/objects/wam`~/wam-gui-scale.test.ts:
- Around line 24-27: Update getWamGuiScale to calculate a single fit factor and
apply it to both x and y, preserving the GUI aspect ratio despite independent
scale usage and minimum size handling. Update the corresponding test assertion
to expect x: 0.5 and y: 0.5.
In `@ui/src/objects/wam`~/wam-midi.ts:
- Line 31: Update the normalized pitch-bend conversion in the visible
conditional so a value of -1 maps to MIDI 0, using 8192 steps below center and
8191 steps above center while preserving the existing range validation and
rounding behavior.
In `@ui/src/objects/wam`~/WamAudioNode.ts:
- Around line 322-326: Update the asynchronous state persistence in saveState
and replaceState, around getState, to capture the active this.instance or
loadToken before awaiting plugin code and verify it remains current after
resolution. Only then update runtimeData and call binding.update; otherwise
discard the stale state.
- Around line 172-174: Update the host caching flow around hosts.set and the
returned host promise so a rejected host removes its AudioContext entry from
hosts, allowing later WAM loads to retry; preserve successful host caching.
- Line 468: Update the dynamic import flow in WamAudioNode to prevent untrusted
persisted or message-supplied URLs from reaching import(url) directly. Validate
the URL against an approved-origin policy before module evaluation, or load
untrusted WAM modules through an isolated sandbox origin, while preserving the
existing default-export validation.
- Around line 429-430: Update mountGui() and unmountGui() to increment a shared
GUI-generation token at the start of each operation, and have the asynchronous
createGui flow capture and validate that token before assigning or mounting.
When the token is stale, destroy the newly created GUI instead of storing or
appending it, while preserving the existing instance checks.
In `@ui/static/content/objects/wam`~.md:
- Line 104: Complete the sentence in the WAM entry URL warning by adding the
missing verb while preserving its meaning and the existing trusted-source
guidance.
- Around line 12-16: Update the WAM documentation to use the exact UI labels:
replace “Browse WAMs” with “Browse community WAMs,” “Use a custom WAM URL” with
“Load from URL,” “Save WAM state” with “Save state,” and “Copy WAM state” with
“Copy state.”

Restore the gm~ shorthand or provide a migration.
This change removes the existing gm~ shorthand. Users can no longer create the General MIDI instrument through that shorthand. The WAM objective does not require this removal.
Restore the entry unless the PR intentionally removes gm~ support. If removal is intentional, update affected tests and user documentation.
