Configuration

The durable section is resolved through the best backing the running composition offers:

Backing	When it is chosen	Where the values live
settings namespace	the settings service exposes register(namespace, schema)	the platform's own settings document, under stock-ticker:
JSON document	otherwise (the normal case on the 0.2 line)	$DSH_HOME/stock-ticker.json, mode 0600
process memory	a read-only harness home	for the session only

The browser half never touches the settings RPC. The Host's Web settings surface serves an allowlist of in-box namespaces, so an out-of-tree namespace answers settings-not-exposed; configuration therefore travels over this plugin's own /api/stock-ticker/config route, and the settings page and the mini-window are two views of one shared mirror.

Settings fields

Field	Default	Meaning
watchlist	[]	Instruments, in display order. At most 24.
maxCurves	6	How many rows get an intraday curve (1–24).
refreshMs	15000	Poll cadence during trading hours (5000–300000).
visible	true	Whether the panel is mounted.
opacity	1	Panel opacity, 0.35–1.
pinned	null	{ left, top } once the panel has been placed.

Each watchlist entry is { code, name, market }, where code is six digits and market is one of sh, sz, bj.

Writes are strict: an unknown key or a wrongly-typed value is refused with 400 rather than silently merged, because a silently-dropped field looks to the user like a save that did not stick.
