Phase 1.0AJ: offline primitive source audit
Status: HYBRID_PRIMITIVE_REUSE_CANDIDATE_GAPS_REMAIN_TARGET_CODE_BLOCKED
Date: 2026-07-29
Official shsrv v0.7 remains useful only for the BigApp creation and replacement lineage. Its loader implementation is not reusable: remote calls are unbounded, and several alias-unmap, descriptor-close, host-unmap and rollback results are discarded.
The hash-bound hardened chimera-elfldr fork supplies better candidates for
remote execution and cleanup. Its ptrace calls have monotonic deadlines and a
step ceiling, registers are restored, credential restoration attempts every
field, and acquired breakpoints, descriptors, mappings and children are handled
by centralized cleanup with reported failure bits.
This is not yet a complete BigApp loader. The hardened cleanup state does not model every temporary JIT descriptor, alias and host mirror needed by the v0.7 mapping lineage. It also clears ownership bits after failed cleanup, so a composition must make child termination the fail-closed terminal owner rather than treating failed release as successful release. BigApp identity/correlation, partial remote copy, final protection, sync and full rollback remain unbound as one transaction.
The decision is therefore hybrid reuse by composition, not source copying: retain v0.7 as provenance for BigApp creation, reuse only reviewed hardened primitives, and first extend the Phase-1.0AI host model with every temporary resource and cleanup failure. No target source, build or device action is allowed by this audit.
