pnpm pack produces a 12 KB tarball with only the two halves and the bundle
patch; it was installed into a throwaway profile to prove it works and
that both halves parse. The notes make the composition step explicit,
because a package can sit in a profile without ever loading -- which is
the state dsh-bottom-info-bar is in on this machine.
The plugin manager accepts an absolute local path, so the package can be
installed from this workspace. Two requirements make or break it: a DSH
peer range (runtime is 0.2.0-rc.2) and a declared bundle patch. Notes that
HMR is absent from the desktop profile, so a restart is required and the
restart is therefore the last step.
Spike proves response.body.tee() splits a real routerai SSE stream: the
consumer sees chunks progressively (first at 1ms of 1643ms) and our branch
still recovers the generation id and usage.cost. It also found a real
defect -- a rebuilt Response loses url, which the OpenAI SDK reads -- and
that Object.defineProperty is the only way to restore it.
Records what was verified against the live routerai API and the harness
code: the provider reports usage.cost on every response, the harness
discards it in mapUsage, and the cost can still be recovered by wrapping
globalThis.fetch while session attribution rides the llm/stream seam.
