GATE

A workbook edit supplies typed cells, an expected revision and dependency/simulation context.
Required scope, evidence identity, input shape and applicable independent review must be present.

SENTINEL

Preserve immutable revisions, deterministic recalculation, concurrency checks and audit evidence; keep Pearl simulation partitions distinct from measured cells.
Watch stale evidence, changed source roots, unsupported type conversions and requests beyond the named profile.

AUDIT RECEIPT

Record request identity, source version, assumptions, input, proposed result, actual outcome and reasons for HOLD or DENY. One successful stage does not override another's veto.

SPECIFIC CHALLENGE

A stale revision or incompatible unit must not overwrite prior work or coerce missing values to zero.

BOUNDED RESULT

Return a new revision with recalculation evidence, or reject/hold a conflict. Results do not authorize external effects.
