Theseus core:
- addons-host: manifest.category ("plugin") propagates through snapshot(); new
addon API surface checkAndStageSelfUpdate() + restartApp() so a plug-in
can offer in-panel "update now → restart to apply" without pushing the
user to Settings.
- main.js: wires the two new hooks into the AddonHost constructor.
- settings.html: Extensions listing filters out category==="plugin"; those
add-ons live in Plug-ins instead, single source of truth.
Aegis 0.6.31:
- BTC picker trimmed to Signet only; testnet3 hidden (adapter kept so any
existing wallet still loads).
- Wallet strip groups by chain, not chain:network; ticker gets a ▾ chevron
and a dropdown listing every subnetwork with its own totals. Mainnet
reads as the plain ticker; testnets carry a small Chipnet/Signet/Sepolia
pill inline.
- Per-unit price sits directly under the ticker; amount + fiat mirror on
the right — one glance covers name/price/holding/value.
- + Add and ⋯ More promoted from the strip into the header's action row,
next to the new ✎ chip (was the redundant top ⋯). Duplicate "Manage
current wallet" entry removed from the More menu.
- Footer update chip is a two-step flow via the new API: stage → restart.
Falls back to opening Settings on any Theseus that lacks the hooks.
- Manifest declares "category": "plugin".

// Theseus add-on framework — loader + API surface.

|
||
// Add-ons live in <userData>/addons/<id>/ as ordinary folders on disk. Each
|
||
// carries an `addon.json` manifest and (per the manifest's `main` field) a
|
||
// CommonJS entry that exports `activate(api)` and optionally `deactivate()`.
|
||
// Nothing about an add-on ships in the Theseus repo or installer — drop a
|
||
// folder, restart Theseus, it's live. This is the same trust model as
|
||
// dev-mode browser extensions: the user is choosing to run local code with
|
||
// the app's full privileges.
|
||
//
|
||
// Loading is synchronous at app-ready time; there is no hot-reload. Failed
|
||
// activations are logged and skipped without breaking the app.
|
||
//
|
||
// Persistence:
|
||
// settings.disabledAddons — ids the user has toggled off
|

// <userData>/addons-data/<id>.json — per-add-on kv store (api.storage)
