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.

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 may set a bounded environment (loader variables denied) and up to 8 small
data files under .demo/; the reason step sees conclusions and may not re-propose
them; a task spend limit concludes its intent, not the search; finish wins over
stray tool calls.

The agent passes a manifest file or project directory; pip uses -r for
requirements files and the directory for pyproject/setup, npm ci/install runs in
the directory, composer/maven/gradle likewise. Build and verify failures carry
phase, exit code and a sanitised stderr tail.

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.

budget_spent carries end_detail (spend, task_spend, reason_rounds, ...); a task
whose allowance cannot cover the next call finishes with its facts; per-task
metrics in pilot records; input reservation bytes/2 + 1024 per message (measured
3-4x over-reservation before).

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.

20 development pairs, one per repository, 4 per language, 5 per family; identities
in a gitignored manifest, counts and digest committed. Executor smoke drives one
executor task end to end without a model and fails loudly on an unread clone.
kube-ax operator constraints as steering.

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.
