Override Tier
override tiers, governance tier, configuration tier, token override, governed extension, lockedDefinition
In the Core (the Agentic DS direction), the permission category for a change: configuration (within an existing contract, automated checks and one named reviewer), extension (changes the contract and needs governance review), or locked (no ordinary brand or agent override)
The Agentic DS direction (2026-09-24) derives most permissions from file, category, and action, with per-field metadata for exceptions, pairings, and rationale. Configuration replaces the earlier name Token tier because it also covers non-token choices. No approval system implements them yet. Where cwds provenance records where a value came from, the tier records who may change it and how.
Governance as data, with three tiers: configuration, extension, and locked. Using an existing touchpoint and adding a new one are different actions and may have different tiers even in the same file.
The draft includes locked examples, including base defaults and accessibility requirements. A complete, owner-approved inventory of regulatory locks has not been established. Changing a lock itself is a separate decision involving the owner of its rationale; ordinary extension approval does not remove it.
What is locked, and on whose authority
The accessibility locks in the draft are not all the same kind of lock, and the difference decides who can lift one:
| Lock | Kind | Source |
|---|---|---|
| DOM and focus order match reading order (the media callout's heading, body, call to action) | WCAG requirement | 1.3.2 Meaningful Sequence, 2.4.3 Focus Order |
| No arrow-key navigation between accordion headers | Local policy | The APG makes arrow keys optional; the draft forbids them to keep nested widgets from fighting over the keyboard |
| Nested tabs must look different from each other | Local policy | A usability judgment, not a WCAG success criterion |
A WCAG lock stays locked whatever anyone decides. A policy lock can be lifted, but only with an accessibility specialist's sign-off. The draft already requires that owner for any change to an accessibility lock.
The regulatory locks have no members yet. The nearest thing on record is the ISI tray: cwds's contract calls its summary "regulated copy that stays on screen". That is observed, not ruled. The list is for whoever owns MLR review to write, not for this glossary to infer.
