# Quantum and hardware model contracts

This bounded source publication adds twelve existing contracts and their English
knowledge cards, regression fixtures and MasterSuite fields. Nine sources retain their exact bytes; three early modules receive only the
standard five-line license header. Their remaining source bytes are unchanged. No private Git history, raw conversations, working logs or
grant documents are exported. The machine-readable [source manifest](quantum-series-export.json)
records module hashes and the [check summary](quantum-series-checks.json) records
checks on this public tree. The later independent whole-stack audit is separate.

The contracts cover quaternion algebra, ideal MZI maps, discrete skyrmion weights,
NV population/Pauli models, phenomenological organoid STDP and fungal conductance,
mean optospintronic momentum accounting, a Boolean IVC ledger, polynomial DAS,
ideal teleportation and entanglement swapping, binary-label filtering, and the
Steane code. Their equations and assumptions do not compose automatically into
a physical device, authenticated protocol or certified quantum memory.

Steane recovery covers canonical single X/Z/Y errors with ideal checks; the
distance excludes global Pauli phases. Purification is a conditional independent
binary-phase filter, not a complete BBPSSW/Deutsch implementation. DAS assumes
static authentic distinct shares and independent uniform requests. The IVC ledger
does not authenticate low-level cryptographic proofs. Biological viability,
thermal safety, physical coherence, hardware admission and authorization are
not established. The Third Obligation remains OPEN.

This publication preserves the previous full-validation checkpoint. It does not
promote historical private verification into a new public beta checkpoint.
