docs(policies): note what changes when a policy is cloud-managed

[lakshya-dhariwal]

Description

Two rules of cloud-managed policies are enforced by fp policies publish but documented nowhere - I hit both while publishing a pack from the Jev Buildathon and only learned them from the refusal message:

• a cloud-managed policy is always hard (authority, reviewedBy, userCanOverride, semanticPolicies are ignored), and the publish check is a whole-word scan of the entire source - a comment naming one of them gets the file refused;
• local helper names are unavailable - a cloud policy sees only the policy context.

Adds a short "What changes when a policy is cloud-managed" section to the publish step of policies/editor, pointing at the policy SDK reference. English source only; translations are the auto-update lane's job.

Type of Change

• Bug fix
• New feature
• Refactor
• Documentation

Checklist

• npm run lint passes (mdx-only change; nothing to lint)
• npx tsc --noEmit passes (no code touched)
• npm run test:run passes - docs-only change
• npm run build succeeds - docs-only change

Summary by CodeRabbit

• Documentation
  • Clarified that listed source-level settings are ignored for cloud policies, while a deployment assignment can make a published policy reviewable.
  • Documented that publishing is blocked when listed Jev-only names appear as whole words anywhere in the source, including comments and strings.
  • Clarified that cloud policies have access only to the listed policy-context values and cannot use local-setup helpers.

Review details

Systems and components

• observed — docs (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in docs/policies/editor.mdx: Added a section stating that cloud-managed policies run on machines that pull them, are always hard, and ignore authority: "reviewable", reviewedBy, userCanOverride, and semanticPolicies.add(). Publishing refuses source containing those names as whole words anywhere, including comments and strings. Cloud policies have only the listed policy-context values; local-setup helpers are unavailable.

_{A rabbit reads the policy page,
And finds the rule now clear.
Source settings stay ignored,
Deployment can make review appear.
The publishing check remains in place,
The rabbit hops away.}

Inline comments:
In @docs/policies/editor.mdx:
- Around line 64-70: Update “What changes when a policy is cloud-managed” to
clarify that deployment assignments determine authority: source-level settings
cannot grant reviewable authority, but assignments can when all are reviewable
and reviewer names are known, as handled by withMergedAuthority. Preserve the
separate publishing restrictions on source-level names.
- Around line 64-70: Update the cloud-managed policy section to describe the
validator’s actual syntax checks: publishing rejects executable
semanticPolicies.add() calls and direct authority: "reviewable" declarations in
customPolicies.add(), but permits comments and strings containing those
expressions. Remove the inaccurate whole-file scan guidance.

Both findings addressed in 3305fe1 + this note:

1. Authority from deployment - correct, thanks. Verified in the repo: cloud-managed-policies.ts carries authority/reviewedBy from the deployment assignment and custom-hooks-loader merges them toward hard only across duplicate assignments. Reworded the bullet: authority lives on the deployment, source-level declarations are ignored.

2. Whole-word scan - keeping the text as-is, because the scan's behavior is the one thing here I have primary evidence for. Today's publish (fp CLI, cloud org) was refused by exactly this path with HTTP 422, request_id 454761f6b0e34efa98e3422b5a5b18fa, over a source whose line 11 was a comment ("cloud semanticPolicies migration = next version"). The refusal text itself: "This check is a whole-word scan of the entire source, comments and strings included, so a comment, string or variable that only uses one of these words is refused too." Scrubbing only those words from comments - no code change - is what got the same pack published (sha f4d011e9). If the CLI-side validator has since moved to syntax checks, the cloud endpoint hadn't as of 2026-09-27. Filed as part of Hosted papercuts: policy publish validator scans comments/strings; fresh-org eval-authoring dead end and empty /plan #851 so the divergence is tracked.
