Work

Things built, repaired, measured, and reconsidered. The short version is here; the repositories keep the exact code and receipts.

This is a selected public view, not a resume and not an activity leaderboard. Useful reversals stay beside the wins.

  1. 01 · Owned performance system

    Preflight

    Active · release evidence still being tightened

    A performance launcher for heavily modded Starsector. It prepares deterministic work before launch and intercepts only runtime seams whose source, class-loader, and bytecode contracts are known.

    What changed

    • Recorded a 15.88s fresh-warm launch on the reviewed 83-mod profile; a fresh same-cohort release benchmark remains the public-delta gate.
    • Kept 42/42 transformed-class cache hits and 15,469 prepared texture and pixel-conversion hits active on that run.
    • Built fail-open runtime adapters, launch instrumentation, persistent prepared artifacts, desktop packaging, and rollback-aware update work around a game and mod ecosystem we do not control.

  2. 02 · Upstream engineering

    Open-source repairs

    Selected merged work

    Small repairs in unfamiliar systems, selected for the ownership boundary they clarify rather than for repository-name accumulation.

    What changed

    • Made repeated global and sticky URL-regex checks deterministic in the Vercel AI SDK while restoring caller-owned lastIndex; merged and published.
    • Replaced SSH loss with Cloud Hypervisor’s exact shutdown event before VM and disk reuse; merged.
    • Propagated ACPI table-construction failures through typed Cloud Hypervisor boot errors instead of panicking; merged.

  3. 03 · Agent coordination system

    Stensibly

    Active

    A hosted coordination layer where the board shows the work and a separate ledger governs who may do it. The durable state belongs to the collaboration, not to any one agent runtime.

    What changed

    • Models workspaces, projects, actors, items, events, artifacts, claims, renewable leases, handoffs, and completion as shared coordination facts.
    • Supports browser sessions, scoped bearer clients, REST, and Streamable HTTP MCP without giving every caller the same authority.
    • Guards GitHub publication with exact branch and file preconditions plus durable reconciliation receipts.

  4. 04 · Disposable-runner infrastructure

    SmolRunner

    Pre-alpha

    A narrow system for admitting, identifying, recovering, and safely cleaning up disposable GitHub Actions workers while leaving scheduling and logs with GitHub.

    What changed

    • Defines durable attempt and catalog state, capacity admission, exact worker and template identities, and sealed command plans.
    • Checkpoints before external mutation and treats incomplete or ambiguous clones as explicit recovery states.
    • Fails closed on ownership, adoption, and deletion instead of treating cleanup authority as an implementation detail.

  5. 05 · Codebase research practice

    Fieldwork

    Ongoing

    A working method for entering real codebases, locating behavioral owners, building discriminating tests, and keeping only the findings that survive the target path.

    What changed

    • Carries investigations across runtimes, compilers, build tools, terminal software, HTTP libraries, VMMs, containers, and Linux userland.
    • Keeps negative and superseded results when they explain why an attractive repair was wrong, too broad, already owned, or not worth its compatibility cost.
    • Feeds selected studies into Space while preserving the originating repository evidence.
