ObjectStoreExecutor.submit re-PUT the identical command.json on every
0.2s result poll, so a task running minutes wrote ~1,500 versions of one
engine-queue/search-exec/<id>/command.json. On the versioned memory
bucket that was the dominant growth: 109,715 versions, 10.3 GB (91% of
the bucket). retry_mailbox already retries a lost PUT acknowledgement
internally, so one upload per task is the correct delivery guarantee.
Guard the PUT with an `uploaded` flag: upload once (still retried on
transient failure), then poll only the result. One command.json version
per task instead of ~1,500. All submit semantics preserved.
59 executor tests pass, ruff clean.

A lockless npm project (e.g. glance, 2015) resolved an unpinned transitive range to the
latest major ([email protected] -> mime@4, which dropped .lookup()), so the built app crashed
serving files -- a build-reproducibility defect, not an app or agent fault. The executor
now, for the npm-install (no-lock) case only and only when .git is present, resolves
dependencies as of the checkout's HEAD commit date via `npm install --before <date>`,
giving era-appropriate, compatible versions. npm ci (lockfile present) is untouched, and
any git/date failure falls back to plain install. demo.py also recognizes
npm-shrinkwrap.json as a lock for the ci-vs-install choice.
Tests: executor + smoke 75 passed, demo 107 passed; ruff clean; mypy clean on executor.py.
Executor-side change -> image rebuild required.

Built projects spool to /workspace without package caches (cap 1 GiB, both
sides); a plain-text model reply is fed back once; mailbox PUT/GET retry for up
to 90 s with idempotent re-send by seq; executor tasks are deleted on every exit
path.

Reasons carry type plus a sanitised message tail; command failures carry phase,
exit code and bounded stderr. Scratch walk tolerates directories pip removes
mid-walk; writable /workspace/home and runtime paths. Capacity retries delete a
possibly created task before resubmitting. Docker smoke checks the image first.

Demos are data the verifier executes (fixed build recipes, runtime+path start,
HTTP/CLI steps with captures; the canary is never referable). The agent loop with
the key never runs repository code: executor tasks without a key exchange commands
and results through presigned objects. AX capacity errors are back-pressure with at
most 2 tasks in flight; caches and builds under /workspace with a 2 GiB guard;
verifiers take one presigned archive per side. Launcher fix: private /dev in bwrap.
190 tests on the host; probe 5/5 demonstrated.
