The package exported six functions, four of them shaped by one SDK's
transport each: a dispatcher factory, a `node:http` agent factory, a
proxy-URL lookup, and a policy accessor. Review asked whether the call
sites could converge instead of the package growing an export per SDK.
They could, and each removal took a whole shape with it:
- The OTLP exporter moves to the SDK's `fetch` delegate, retiring
`createNodeHttpAgent`. Its Node-version floor goes too: `proxyEnv` on
an `http.Agent` needs 22.21 or 24.5, inside the engines range, so
telemetry was direct on 22.19, 22.20, and 24.0-24.4. The cost is
`compression`, a Node-transport option; the plugin now refuses it,
`keepAlive`, and `httpAgentOptions` at load instead of ignoring them.
- `web-fetch-http` builds its own address-pinning agent under an
annotated `proxy-exempt:` exemption, retiring `createDispatcher`.
Pinning is per-request state a process-wide dispatcher cannot hold.
- E2B reads `route.proxy`, retiring `proxyUrlFor`.
What remains is `installProxyFromEnvironment`, `proxyRouteFor`,
`proxyEnvironmentForChild`, and `clearedProxyEnv` — one per way a caller
can need the policy. Installation absorbs resolution and diagnostic
reporting, which no caller needed apart.
`proxyRouteFor` also closes a defect the old accessor made expressible:
`web-fetch-http` read the policy to decide whether to pin, then read it
again to build a transport, so an unmount between the two returned a
direct, unpinned agent for a URL the first read had cleared as proxied.
A route carries the answer and the transport that answer assumed.
Every egress spec now installs through `installProxyFromEnvironment`, so
no test asserts a policy object a real launch could not produce.
Master moved 212 commits. Conflicts were eight `package.json` and nine
`tsconfig.json` files, all dependency-and-reference unions: master dropped the
`runtime-diagnostics/invariants` reference across packages while this branch
added `util/http-proxy`. The lockfile, `tsconfig.base.json`, and the module
graph were regenerated rather than merged by hand.
Master also brought `verify-package-invariants`, which rejects an empty
invariant companion. This package's companion was empty by design, so it is
gone with its publication wiring — the export, the `files` entry, the project
reference, the `dsh-invariants` peer, and the test. Master did the same across
`util/`. The README carries the reason sentence that gate requires.
Carried in the same commit, because the review arrived while the merge was open:
`e2bApiUrl` moves out of the `dsh-e2b` entry into `src/api-url.ts`. Code Entropy
flagged it as a public name with no consumer outside its own package; the seam
keeps its URL-precedence test, which is worth having directly — getting that
order wrong hands a proxy the control-plane traffic and its API key.
A jump clicked while the Load-earlier pull was in flight fell through the
settle effect's nearest-turn fallback and landed on the wrong row. The
effect now keeps the pending jump (busy pulse stays) while loadingOlder is
true and a retry tick re-issues loadThrough when the pull settles.
Also repins the long-interactions e2e rail block to the outline-rail
semantics (fixed mark pitch, load-and-jump labels) and covers the
loadThrough forwarding paths in apply-inject and the client-runtime stub.
Outline entries gain the turn's final text-bearing assistant preview:
each assistant message overwrites a state draft and turn/end commits
the survivor, matching the loaded rail's findLast semantic; the bare-
array wire keeps its identity across draft changes, so pushes stay at
three per turn. Preview budgets shrink to the rail card's clamps — one
50-character prompt line, up to three 120-character response lines,
ellipsis on clip — on loaded and unloaded turns alike (stateVersion 2
discards v1 cache rows).
A mid-paging landing keeps the jump armed with the target row as its
paging anchor, so later chunks and the load-earlier button's unmount
cannot drift the landing; the loader's completion runs one final
correction unless the reader already scrolled off the target. Adds the
browser contract: full outline ladder, keyboard jump on an unloaded
mark, landing geometry, and rail fades.
