Policy and governance

Governance is data, held server-side, edited live, and exportable as one document. It is never a fork of the pack's tool.json - the open-source tool definition stays untouched and the control plane overlays its opinion on top.

Everything on this page is live-editable in the console (This Deploy → Tools / Feature flags, Grants) and reaches connected shells on their next poll.

Tool overlays

One overlay per tool, versioned. PUT /api/v1/policy/overlays/:toolId under policy.edit (admin by default, grantable to a brand group so a brand team can govern inputs without holding the admin role). Saving audits before/after and busts the render cache for exactly the affected renders.

The console preserves saved format restrictions and input defaults when you edit inputs, visibility or watermarking. An unchanged preset or choice keeps its saved type, including strings that look like numbers. Enter a JSON array for choices containing commas or typed values, for example ["blue, green", "42", 42]. Comma-separated simple choices remain supported. An explicitly edited blank preset locks to an empty string. Remove a rule with Remove; clearing its groups is an error rather than an implicit deletion. Group names containing commas can be entered as a JSON array, for example ["Sales, EMEA", "brand"]; unchanged group lists are preserved.

Use Move up and Move down to order an input's rules. New exceptions are inserted before the first rule for everyone, and the editor warns when an earlier rule covers the same groups. Closing, switching tools or navigating away with a draft offers Keep editing or Discard changes. Leaving the page also invokes the browser's unsaved-changes warning. A failed save retains the draft.

Visibility

"visibility": { "groups": ["brand-team", "marketing"] }

A tool with a visibility block is absent from the catalog feed for anyone outside those groups - not greyed out, not hidden client-side. * means everyone.

Per-input access

inputAccess maps an input id (or * as the default) to an ordered rule list; the first group-match wins, and no match means editable.

"inputAccess": {
  "logo": [
    { "groups": ["brand-team"], "level": "editable" },
    { "groups": ["*"], "level": "locked", "value": "acme/logo" }
  ],
  "discount": [
    { "groups": ["sales-managers"], "level": "editable" },
    { "groups": ["*"], "level": "hidden" }
  ]
}

Enforcement is server-side and pre-render: a locked input supplied by a caller is a 422 INPUT_LOCKED, and the locked value is baked into the render regardless of what the request said. The same pure functions filter the schema the shell sees, so the UI and the enforcement can't disagree.

Give the overlay a name and a rule an optional reason and the person meets an answer instead of a dead control: the resolved access carries by (the overlay name) and reason into org-config, where the shell prints them under the input, and into the 422 body as { "error": { "code": "INPUT_LOCKED", "input": "bg", "by": "...", "reason": "..." } }, so an agent driving a render reads the same explanation. Both are optional and an unnamed overlay attributes nothing, exactly as before.

The enforce block

defaults is accepted and stored, but is not applied to initial tool inputs by the current org-config or render paths. Locked presets do enforce values today. Two more keys (c2pa, escalation) are declared in the overlay type but the write paths do not accept them yet - C2PA signing is instance-wide via render.c2pa (c2pa), and chain binding works as approvals describes. See status.

The console offers Always watermark, Never watermark and No rule for new edits. An existing until-approved setting is retained with a warning that it is not enforced. Stored fields the policy writer cannot preserve, such as enforce.escalation, block a console save with an explanation rather than being silently removed. This form does not protect against a concurrent administrator replacing the same policy; the API remains a full replacement.

Profile governance

Identity fields the IdP owns are managed, not editable. claimMap decides which claim fills firstname, lastname, email and title; those fields come back to the shell as mode: locked, source: idp, which is what renders the padlocks in the shell's profile view. The user keeps everything the org has no opinion about.

Feature flags

Managed AI is a service execution switch with an additional deployment approval ceiling; it has no personal override. See managed AI. The other flags below govern personal defaults and visibility.

The control plane governs the shell's per-user toggles it knows about, instance-wide. Two knobs per flag:

Governable today (ids are the shell's own):

GET /api/v1/policy/flags, PUT /api/v1/policy/flags/:flagId, same policy.edit gate. The off + hide combination is how a seasonal surprise ships dark: stage it now, flip the default on the day and it lights up without ever having shown a switch.

Policy-as-code

One canonical document holds the whole governance state, serialized deterministically so logically-equal states hash identically:

• grants
• tool overlays
• approval chains
• catalog-provider config + exposure (never credentials, never runtime state, never the enable kill-switch)
• feature-flag governance
• org-defined catalog metadata definitions (catalogFields) - the fields an org files its assets under (catalog). The definitions are policy; the per-asset values are not, and never appear in the document
• hidden catalog tags (tagRules), one entry per scope: * for the whole catalog or provider:<id> for one provider (catalog). The key is left out when nothing is hidden, so an earlier export hashes the same

lw export --out governance.json                # GET /api/v1/config/export
lw apply governance.json --dry-run             # POST /api/v1/config/apply?dryRun=1 - shows the diff
lw apply governance.json                       # apply
lw apply governance.json --prune               # also delete store-only entries

The diff reports create/update/delete/unchanged per category, and the response carries the document hash. Two guards:

• Applying a document that creates or removes a grant on any owner-only action (instance.config, catalog.provider.credential, catalog.provider.publish, scim.manage, token.manage) requires the owner role (403 OWNER_ONLY_ACTION).
• Entries that a config-managed catalog provider owns are conflicts, not overwrites (409 CONFIG_MANAGED) - edit instance.json and redeploy instead.

Pruning a catalogFields entry removes the definition only. Values already filed under it survive, hidden from every served surface until the definition comes back, so a taxonomy change never destroys the data filed under that field.

Seeding at boot

LW_SEED_CONFIG=./governance.json npm start

Idempotent, so it is safe to leave set. It is trusted (filesystem access), so it bypasses the owner-only HTTP guard and may seed owner-only grants - it still never enables a provider or stores a credential, because neither is in the document. This is what makes a fresh deploy come up already governed, and governance reviewable and promotable staging → prod from git.
