Consume the governed read boundary¶

The stable current consumer boundary is PR11.11 CurrentStateGovernedPlayerWindow.

It is designed for a product that needs to present governed capability state and advisory progression without becoming a new state-selection or capability-update authority.

What a consumer receives¶

A governed product/read snapshot binds:

the complete current-selection history head portfolio;
the current selected state set;
the freshly governed PR11.9 progression frontier;
exact digests that bind those sources to the rendered snapshot;
governance metadata required to distinguish meanings such as SELECT, CLEAR, and ABSENT.

The raw presentation window exposes every and only current SELECT state. Governance history remains available outside the raw presentation surface so that omission from display does not erase meaning.

What the consumer does not get¶

The request surface does not accept:

caller-selected state_id
caller-selected subject
prebuilt current portfolio
prebuilt governed frontier
selected_state_ids
selected frontier object
write-back command

That absence is intentional. A product may ask for a view; it may not decide what the governed current state should be simply by choosing convenient inputs.

Fresh validation is part of consumption¶

A canonical JSON round-trip is useful for transport and audit, but serialization does not create authority.

serialized snapshot != live authority

Before relying on a restored snapshot as current, validate it against the live governed source history and authority bases. PR12.14 proves that historical appends stale older PR11.10/PR11.11 artifacts even when a new governance act is timestamped no later than the old snapshot's generation time.

Time semantics¶

The product boundary distinguishes semantic time from derivation time.

A current state may have been derived later while representing an earlier epistemic state.as_of. A product request earlier than the selected state's semantic state.as_of fails closed rather than silently filtering the state from view.

Malformed generated_at < as_of requests and governance acts from after the product generation time are also rejected by the owning layers.

Consumer invariants¶

VISIBLE != CURRENT
HIDDEN != DELETED
CLEAR != ABSENT
PRESENTATION != AUTHORITY
PROGRESSION != READINESS
PROGRESSION != PERMISSION
CURRENT != MASTERY
PRODUCT VIEW != CAPABILITY WRITE-BACK

These are not UI slogans; they are the integration contract.
