Archives are gzipped and uploaded in parts of at most 90 MB with per-part
digests (edge request limit); pip installs ignore the task venv so transitive
dependencies land in products; the verifier sets NODE_PATH and the Java
classpath from products when starting the app.

HTTP start waits up to 90 s (CLI 30 s) with TCP then HTTP probing; app stdout
and stderr tails are recorded; tool-call turns get 4096 output tokens with one
retry on truncation; tasks get 40 steps with reminders.

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.

Demos declare their oracle within the family allowed set (injection: sql or
command; output_encoding: xss; untrusted_destination: ssrf; path: path);
builds and app starts use the search memory budget instead of the 256 MB tool
limit (npm died with SIGTRAP); malformed tool-call JSON is fed back once.

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.
