QuantumOS v0.4.0
Immutable
release. Only release title and notes can be modified.
The agent-native arc completed and battle-tested. PRs #151–#183.
Added
- Quantum stack (epics #148/#149/#150, PRs #151–#155):
qsv, an exact Gaussian-integer
quantum state-vector citizen (zero rounding, digest-vs-host-mirror CI gate); a capability-gated
kernel QPU job broker (SYS_QPU, opaque circuits only, per-manifestqsubquota); a COM2
quantum-submit transport over the attested bridge; a host gateway dispatching
PennyLane lightning.qubit / lightning.gpu (cuQuantum) / CUDA-Q / qBraid real QPUs, all
cross-oracled against the exact engine (≤1e-9). - Agent society arc (PRs #171–#179): the end-to-end agent-native showcase (
agentdemoboot
token) — an orchestrator citizen delegates narrowed field capabilities to sub-agents it spawns
itself over spawn-time parent↔child IPC channels; content-consensus digests verified per
kernel-vouched sender; division-of-labor private field workspaces; a society of
societies — two kernels exchanging verified society results over the field-sync wire; the
ring-3 roster refactored tokernel/src/citizens.c. - CI gates: qsh singleton-IPC-cap invariant (#176), disk upgrade path — frozen audit-ledger
home survives field growth (#183), qseed-handoff smoke incl. the errno-collision gate (#168).
Fixed
- Adversarial bug-hunt campaign (PRs #156–#167): ~31 real bugs across quantum, networking,
trust-core, process/memory, and lifecycle code — 0 false positives across 8 hunts. Highlights:
closed a ring-3 → whole-OS DoS in syscall copy-in/out (#158→#160,COPYGUARDgate); DNS answers
bound to their query (on-link poisoning, #162); spawn error paths reclaim address spaces (#164);
argv buffer cleared between spawns (#165).
