Seed the institutional essay the page defers. The thread installs elite pacts as a second object next to the dyadic implicit treaty, and names a discriminator against an explicit constitution: can you cite a section number, and can a court name the clause? Spain's pacto del olvido (informal among parties; Ley 46/1977 as proxy; not in the 1978 Constitution) versus South Africa's sunset clauses (written into Act 200 of 1993) versus Chile's 1980 lock-in (constitution plus binomial organic law) versus the corporate implicit bargain Shleifer and Summers treat as unwritten and breakable by hostile takeover. Author dispositions stay author-owned.
