Project belongs to another company or does not exist: ${proj

Error message

Project belongs to another company or does not exist: ${projectId}

What it means

Thrown during profile validation when ctx.projects.get(projectId, companyId) returns nullish for a project id listed in a 'selected_projects' scope. The projects.get helper is company-scoped, so a null result means the id is unknown or belongs to a different company. This guards ingestion from binding to projects outside the company boundary.

Solutions

1. Call listPaperclipIngestionCandidates first and restrict the picker to ids it returns for the current company.
2. Strip project ids that no longer exist before submitting, or surface them to the user for re-selection.
3. Verify the companyId passed into the profile update matches the company that owns every projectId.
4. If a project was just created, wait for it to be readable before adding it to the scope.

Example fix

// before
profile.sourceScopes = [{ kind: "selected_projects", projectIds: rawProjectIds }];

// after
const candidates = await listPaperclipIngestionCandidates(ctx, { companyId, wikiId });
const valid = new Set(candidates.projects.map((p) => p.id));
profile.sourceScopes = [{
  kind: "selected_projects",
  projectIds: rawProjectIds.filter((id) => valid.has(id)),
}];

async function filterExistingProjects(ctx, companyId, projectIds) {
  const candidates = await listPaperclipIngestionCandidates(ctx, { companyId, wikiId: DEFAULT_WIKI_ID });
  const valid = new Set(candidates.projects.map((p) => p.id));
  return projectIds.filter((id) => valid.has(id));
}

function isLikelyProjectId(id) {
  return typeof id === "string" && id.length > 0 && /^[a-zA-Z0-9_-]+$/.test(id);
}

try {
  await updatePaperclipIngestionProfile(ctx, { companyId, spaceSlug, profile });
} catch (err) {
  if (/Project belongs to another company or does not exist/.test(err.message)) {
    const id = err.message.split(": ").pop();
    profile.sourceScopes = profile.sourceScopes.map((s) =>
      s.kind === "selected_projects" ? { ...s, projectIds: s.projectIds.filter((p) => p !== id) } : s);
    return updatePaperclipIngestionProfile(ctx, { companyId, spaceSlug, profile });
  }
  throw err;
}

When it happens

Trigger: Submitting a 'selected_projects' scope whose projectIds includes an id that was deleted, mis-typed, copied from another company, or pending creation. The lookup happens inside validatePaperclipIngestionProfile, reached via updatePaperclipIngestionProfile.

Common situations: Stale project id cached in a UI form after the project was archived/deleted; cross-company copy-paste of ids; test fixtures referencing a project from a different tenant; race between project creation and profile save.
