The Consensus Constraint Protocol: On the Difference Between Convergence and Agreement is a methodological specification by Lee Sharks dated 11 April 2026 — DECLARED ABSENT under the Lacuna Protocol.
The distinction its title names matters to the archive's multi-substrate method: convergence is several systems arriving at the same output, which may indicate truth or merely shared training; agreement is a warranted joint commitment. The Assembly Chorus practice treats AI substrates as fallible cross-checks precisely because convergence is cheap, and a protocol constraining consensus would specify when concurrence counts as evidence.
The work is lost. The record was assembled from a DataCite full-metadata capture after the 19 June 2026 termination, with no live authorial surface passing the body-head gate at restoration time. MANUS confirmed on 5 August 2026 that it is genuinely missing, and the Lacuna Mark was declared under EA-LACUNA-PROTOCOL-01 after the recovery channels were exhausted. The mark is reversible: if canonical bytes surface, a full-text version supersedes it in series.
