Implements step 1 of Move the Desktop bridge types back to Comfy-Desktop (approved). Desktop reclaims ownership of @comfyorg/comfyui-desktop-bridge-types; the paired frontend PR deletes its copy and depends on 0.2.0 from npm.

Three copies of this contract existed and none matched the runtime bridge: this repo's source (openTerminal, ComfyDownloadProgress.id), the frontend's unpublished 0.1.4 (openModelAccessPage, doc comments), and npm, stale at 0.1.2. This consolidates them.

Changes

  • src/types/comfyDesktopBridge.ts gains openModelAccessPage and the frontend's doc comments — it already had everything else. Package regenerated from it and bumped to 0.2.0.
  • Both preloads now import that source directly instead of the published build of themselves. comfyPreload's ComfyDesktop2RuntimeBridge intersection existed only to re-add members npm 0.1.2 was missing, so it's gone; satisfies ComfyDesktop2BridgeImplementation now binds preload and contract in whichever commit changes either.
  • bridge-types:gen runs prettier, making its output reproducible. The committed .d.ts had been hand-formatted, so regenerating it produced a 145-line whitespace diff. New bridge-types:check regenerates and fails on any diff; CI runs it.
  • Publish workflows ported from the frontend: workflow_dispatch for prereleases, plus on-merge when packages/comfyui-desktop-bridge-types/package.json changes. Both re-verify the generated types before publishing and skip if the version is already on npm.
  • README so the npm page isn't empty.

Preload behaviour is unchanged — nothing on window.__comfyDesktop2 moves.

Verification

typecheck, lint, format:check, test (4341 passed) all green. Both new guardrails were probed against deliberate breakage: adding a member to the type source fails bridge-types:check, and dropping openTerminal from the preload literal fails typecheck.

Before merging

NPM_TOKEN must exist as a repo secret here — 0.1.0–0.1.2 were published by hand, so this repo has never run an npm publish in CI. The token needs write access covering @comfyorg/comfyui-desktop-bridge-types; the package already exists, so scope-create access isn't needed.

Paired frontend PR: Comfy-Org/ComfyUI_frontend#15320 (draft, blocked on this one publishing 0.2.0).

Fold the frontend copy's additions (openModelAccessPage, doc comments) into
src/types/comfyDesktopBridge.ts, the file the preload implements, and
regenerate the package from it at 0.2.0.

Both preloads now import that source directly instead of the stale npm
build of themselves, so comfyPreload's hand-written intersection is gone
and `satisfies ComfyDesktop2BridgeImplementation` binds the preload to the
contract in the same commit that changes either.

A CI check regenerates the package and fails on any diff, and merging a
version bump publishes.

Changes

Bridge type synchronization and publishing

Layer / File(s) Summary
Bridge contract and local type ownership
packages/comfyui-desktop-bridge-types/*, src/types/comfyDesktopBridge.ts, src/preload/*
The bridge contract adds optional openModelAccessPage. Preload code uses local bridge types. The README documents package usage and generation provenance.
Generated declaration and version validation
package.json, packages/comfyui-desktop-bridge-types/package.json, .github/workflows/ci.yml
Generation formats declarations and checks for differences. CI checks bridge type synchronization and requires a higher package version when bridge contracts change. The package version is 0.2.0.
Bridge package publishing automation
.github/workflows/publish-bridge-types*.yml
Reusable and merge-triggered workflows validate versions, skip existing npm versions, and publish missing versions with the selected dist-tag.

Merge Risk: 🔵 Low · up to 090d7

The published bridge contract documents a fallback that does not run when openModelAccessPage rejects, so consumers may not receive the behavior the README promises. The PR is otherwise mergeable with explicit owner awareness of this bounded contract mismatch.

Comment thread packages/comfyui-desktop-bridge-types/README.md
The publish workflow only fires on changes to the package's package.json,
so a PR that edited the contract and regenerated it without bumping would
pass bridge-types:check and merge, leaving npm on the old contract. CI now
fails that PR.

Also fixes the README example, which awaited openModelAccessPage outside a
try and so skipped the fallback the doc comment promises on rejection.
The gate compared against pull_request.base.sha, which is the base tip as
of the PR's last sync rather than the fork point, so main's later commits
were attributed to the PR. Use the merge base, and widen the watched set
to index.d.ts/index.js — both ship in the package's `files`, so either can
change the published entrypoint without the old gate noticing.

semver excludes prereleases from a `>x.y.z` range, so any prerelease bump
failed the gate and the publish workflow's `next` dist-tag path was
unreachable. Pass -p. Dropping to npx also removes a full dev-dependency
install (with native rebuilds) from every PR.

Publishing now fails instead of skipping when the version is already on
npm and the run came from a merge, so a green publish job means it
published; manual dispatch keeps the idempotent skip. Trigger on push to
main rather than pull_request: closed, which passes no secrets for
fork-authored PRs and needs a merge_commit_sha guard. Drop github.workflow
from the concurrency group — inside a called workflow it resolves to the
caller, so dispatch and on-merge runs of one version never serialised.

README: isRemote() is required, not optional; add noopener to the fallback
example; say that the version bump is what publishes.
