Add Link compute APIs to the SDK (#156)

OP OpenVibers committed 4 days ago · bd1b2cfa92 · 37 files, +348 −277

* Expose Link and compute picker in SDK

* Merge remote-tracking branch 'origin/main' into rename/link-1109-SDK

* Release 0.118.0: Link is the SDK's machine module

ov.node is ov.link and the types, bundle, surface and README name 0.118.0. A
link principal token is not a user token, the copied contract types carry the
link actor_type, and the browser-entry list has ./link in place of ./node.

* Release 0.124.0: Link is the SDK's machine module

Merges main, keeps ov.link in place of ov.node (exports, types, esm, browser
entries and jwt principal rule), pins openvibe-contracts v0.372.0, regenerates
the bundle and surface, and bumps to 0.124.0.

++## 0.124.0 (2026-11-09)
++
++- OpenVibe Link: `openvibe-sdk/node` is `openvibe-sdk/link` (`ov.node` is `ov.link`), building

  It has no runtime dependencies. It needs Node ≥ 20, or any browser with `fetch`, Web Crypto and `TextDecoder`. There is no build step. The package is CommonJS with ESM entry points (`import` works). Each subpath has its own `.d.ts`. For a page with no bundler, `browser/openvibe-sdk.mjs` is one self-contained ES module of the browser-safe subpaths (see [Browser without a bundler](#browser-without-a-bundler)). It does not depend on `openvibe-contracts` at runtime: it copies the contract types it uses (from the temporary Contracts sharing branch, a devDependency the tests check them against).

  `ref` is `{ service, kind, id }`. Subjects follow `identity.subject-ref@1`; the common user case is `{ type: 'user', id: 'usr_<ULID>' }`. Members and transfer recipients must be active **user** subjects: a `guest`, `app`, `mod`, `agent`, `service` or `system` subject is refused, and a user subject is checked against Network (batched, cached 60 s) so unknown, banned and deleted accounts cannot be added. A bare subject-id string is never an identity projection. Expiry timestamps are absolute RFC3339 timestamps in the future. Viewer/editor membership is effective for **people** only. Public/link grant viewing to everyone but never grant editing to strangers; private is owner-only. Active pending transfer recipients may preview in every audience. Staff view/edit overrides append audit records even on public resources; staff cannot start/accept/decline another person's transfer. A staff member who is not the owner may narrow access only — set the audience to `private` and remove members — never widen, add a member or raise a role; anything else is a generic 404 like any other non-owner. Owners and trusted staff may manage share settings. Generic 404 responses reveal no resource title or existence through share settings.
