One-second cases are mixed and all two-second missions fail. Later prediction and landing-guard studies still report accepted: false. Engineering note https://louijiecompo.com/updates/ludoweave-replay-controls/ https://louijiecompo.com/updates/ludoweave-replay-controls/ Wed, 30 Sep 2026 00:00:00 GMT M242 through M244 add pause/step, seek/resume and a current/final tick panel with playback state and contextual hints. Recorded world input stays authoritative. Engineering note https://louijiecompo.com/updates/omniweft-worker-recovery/ https://louijiecompo.com/updates/omniweft-worker-recovery/ Wed, 30 Sep 2026 00:00:00 GMT Merged worker lifecycle and restart-expiry handling preserve terminal proposals and the exact prepared request. Uncertain delivery can recover a receipt; expired retention requires reconciliation. Engineering note https://louijiecompo.com/writing/how-long-can-a-drone-controller-fly-blind/ https://louijiecompo.com/writing/how-long-can-a-drone-controller-fly-blind/ Wed, 30 Sep 2026 00:00:00 GMT AeroLoop's retained simulation study recovers from 500 ms missing captures under the tested conditions. One- and two-second gaps expose a failure boundary that prediction and a landing guard do not close. Article https://louijiecompo.com/writing/retrying-ai-workers-without-duplicating-actions/ https://louijiecompo.com/writing/retrying-ai-workers-without-duplicating-actions/ Wed, 30 Sep 2026 00:00:00 GMT Omniweft keeps mutation authority in the parent and policy host. A crashed or superseded worker cannot revive a proposal, and explicit retry preserves the exact request when delivery is uncertain. Article https://louijiecompo.com/updates/aeroloop-rotors-wind-and-landing/ https://louijiecompo.com/updates/aeroloop-rotors-wind-and-landing/ Mon, 21 Sep 2026 00:00:00 GMT Explore measured rotor envelopes, five matched wind comparisons and a calm mission's liftoff, touchdown and motor-disarm events. Engineering note https://louijiecompo.com/updates/omniweft-bounded-native-queries/ https://louijiecompo.com/updates/omniweft-bounded-native-queries/ Mon, 21 Sep 2026 00:00:00 GMT Inspect retained tag and region query pages, compare a stable snapshot with a fresh query, and see the empty result from a session without read permission. Engineering note https://louijiecompo.com/updates/aeroloop-verified-replay/ https://louijiecompo.com/updates/aeroloop-verified-replay/ Sun, 20 Sep 2026 00:00:00 GMT Compare three CPU response plots, scrub their recorded motion and inspect the separate saved-policy reproduction evidence. Engineering note https://louijiecompo.com/updates/omniweft-native-hierarchy/ https://louijiecompo.com/updates/omniweft-native-hierarchy/ Sun, 20 Sep 2026 00:00:00 GMT Retained CPU snapshots show preserve-world reparenting, descendant movement and complete rollback after a rejected cycle. Engineering note https://louijiecompo.com/updates/omniweft-room-showcase/ https://louijiecompo.com/updates/omniweft-room-showcase/ Sat, 19 Sep 2026 00:00:00 GMT A scripted Python client assembles five blocks, rejects a forbidden edit and rearranges the room. The portfolio now includes retained Windows GPU frames from the merged showcase. Engineering note https://louijiecompo.com/updates/omniweft-local-control/ https://louijiecompo.com/updates/omniweft-local-control/ Mon, 14 Sep 2026 00:00:00 GMT The merged PR-005 SDK adds private local sessions, capability negotiation, typed object transactions and explicit recovery after uncertain responses. Optional Vulkan presentation is also implemented, with separate Windows GPU evidence. Engineering note https://louijiecompo.com/writing/from-python-agent-to-vulkan-frame/ https://louijiecompo.com/writing/from-python-agent-to-vulkan-frame/ Mon, 14 Sep 2026 00:00:00 GMT How Omniweft separates authenticated local control, atomic world changes and optional presentation, with explicit limits on what each test establishes. Article https://louijiecompo.com/updates/verified-replay-presentation/ https://louijiecompo.com/updates/verified-replay-presentation/ Sun, 13 Sep 2026 00:00:00 GMT M241 adds visible playback of verified Clockwork Arena recordings. A full headless check precedes presentation; recorded transactions and inputs remain authoritative, while live gameplay input is ignored. Engineering note https://louijiecompo.com/writing/a-replay-is-more-than-a-list-of-inputs/ https://louijiecompo.com/writing/a-replay-is-more-than-a-list-of-inputs/ Sat, 12 Sep 2026 00:00:00 GMT How consumed input snapshots, world transactions and independent verification make a recording useful evidence. Article https://louijiecompo.com/writing/determinism-with-optional-rendering-and-audio/ https://louijiecompo.com/writing/determinism-with-optional-rendering-and-audio/ Sat, 12 Sep 2026 00:00:00 GMT Separate the reproducibility of a canonical world from the behavior of the devices that present it. Article https://louijiecompo.com/writing/pci-driver-vs-platform-driver/ https://louijiecompo.com/writing/pci-driver-vs-platform-driver/ Sat, 12 Sep 2026 00:00:00 GMT Compare two explicit virtual-device contracts across discovery, MMIO, interrupts and evidence without confusing CPU architecture with bus type. Article https://louijiecompo.com/updates/recording-real-play/ https://louijiecompo.com/updates/recording-real-play/ Thu, 10 Sep 2026 00:00:00 GMT Clockwork Arena can record the input snapshots its play loop consumes and verify them in a fresh headless process. Recording is opt-in, capped at 3,600 requested ticks, and keeps rendering and audio outside the artifact. Engineering note https://louijiecompo.com/updates/cogniform-september-2026/ https://louijiecompo.com/updates/cogniform-september-2026/ Wed, 09 Sep 2026 00:00:00 GMT The CLI now documents inherited-stream sessions and a local MCP adapter for queries, imagination, atomic patches, and revision-linked observations. These adapters add no network listener or remote security boundary. Engineering note https://louijiecompo.com/updates/ludoweave-engine-september-2026/ https://louijiecompo.com/updates/ludoweave-engine-september-2026/ Wed, 09 Sep 2026 00:00:00 GMT Clockwork Arena now documents optional synthesized effects through an explicitly pumped, callback-free audio path. The default Null audio mode remains headless and unpaced; device playback and human listening require separate verification. Engineering note https://louijiecompo.com/updates/makopa-os-september-2026/ https://louijiecompo.com/updates/makopa-os-september-2026/ Wed, 09 Sep 2026 00:00:00 GMT The retained BIOS example is now accompanied by a freestanding Rust kernel and thin UEFI loader. Fixed workloads exercise task isolation, capability-mediated IPC, a bounded approval broker, and a supervisor-readable effect journal. Engineering note https://louijiecompo.com/updates/yocto-qemu-edu-lab-september-2026/ https://louijiecompo.com/updates/yocto-qemu-edu-lab-september-2026/ Wed, 09 Sep 2026 00:00:00 GMT Closed lab manifests now separate x86-64 PCI MSI/INTx and bounded DMA from an ARM64 Device Tree and platform-driver path. The ARM64 peripheral has its own hardware contract and does not expose DMA. Engineering note https://louijiecompo.com/writing/observations-need-world-revisions/ https://louijiecompo.com/writing/observations-need-world-revisions/ Wed, 09 Sep 2026 00:00:00 GMT What Cogniform's revision-linked observations clarify about agent feedback, local transport and evidence. Article https://louijiecompo.com/writing/optional-audio-and-deterministic-worlds/ https://louijiecompo.com/writing/optional-audio-and-deterministic-worlds/ Wed, 09 Sep 2026 00:00:00 GMT A source-based reading of LudoWeave's optional sample audio and the difference between simulation evidence and device evidence. Article https://louijiecompo.com/writing/what-qemu-driver-evidence-can-establish/ https://louijiecompo.com/writing/what-qemu-driver-evidence-can-establish/ Wed, 09 Sep 2026 00:00:00 GMT Reading the independent PCI and ARM64 lab contracts without turning virtual-device evidence into physical-hardware claims.
