transmission, extracted from the platform into its own repository

The sixth plugin out, immediately after photos. A sidecar, a proxy router and
29 web files; no db/ directory, because there are no tables.

── The one thing that is not self-contained ──

The connection lives in `service_connections`, a CORE table, reached through
getServiceConnection/saveServiceConnection/getServiceCredentials. This plugin
declares no schema.

Deliberate: that table is the app store's shared credential store, keyed on
(user_id, service), already encrypted at rest and already read by
app-store/effects.ts. A private copy of the same three columns would be a
second place the same fact could live, and the runbook is explicit that a move
plus a data-format change gives any failure two causes.

The cost, stated rather than hidden: this plugin depends on a core facility it
does not own, and would break if that table changed shape. Photos, by contrast,
owns photos_config outright.

── 38 palette classes paid down, mapped by meaning ──

  blue     downloading / download speed  -> info
  cyan     checking (verifying)          -> busy
  emerald  seeding / complete            -> success
  amber    queued / stalled / warnings   -> warning

Collapsing blue and cyan into one tone would have lost a real distinction in
the status dot, so `checking` went to `busy` — in-progress work, which is what
that tone is for.

── A near-miss worth recording ──

The first copy globbed *.tsx and *.ts and silently missed detail/ and dialogs/
— ten components. tsgo caught it as ten "cannot find module" errors. Worth
stating because it is quiet in the other direction: had those been imported
lazily, the typecheck would have passed and the panels would have broken at
runtime. Check the directory tree, not the file glob.
