Context culling, tier routing, and redaction
blocked_externalRead-only shell for Caster A1 context culling, tier routing, prompt cache prefix, diff-only preference, and secret redaction policy.

Caster Model
Caster Model is the standalone Caster OS model governance shell for Caster A1 context culling, tier routing, secret redaction, local eval work orders, deterministic checks, non-promotion holds, training-disabled receipts, serving-disabled receipts, provider-read blocks, robotics safety, QStorage, event log, and rollback evidence. This fallback is live for navigation and verification only. Model training, serving, promotion, provider reads, dataset reads, model API calls, eval acceptance, production datastore mutation, QStorage writes, event-log appends, rollback, wallet signatures, and public announcements stay blocked_external until deterministic evidence passes.
Read-only shell for Caster A1 context culling, tier routing, prompt cache prefix, diff-only preference, and secret redaction policy.
Local model eval work orders, redacted eval contracts, benchmark classes, deterministic checkers, and non-promotion holds are referenced but not accepted as live evidence.
Model training, serving, promotion, model API calls, provider reads, dataset reads, and endpoint calls remain disabled until strict receipts pass.
Robotics safety dependency, QStorage publication, append-only Caster event log, and rollback require accepted evidence before public claims.
