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.

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 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.
