# ammfast: execution infrastructure failure No implementation was delivered. No source or foundation configuration was changed. The required first real-workload benchmark could not start because the machine repeatedly failed to create processes, threads, and sandbox namespaces. This is a machine failure, not missing requester input; no `.imd-blocked.json` was created. Commands attempted (all returned or were polled to completion within seconds): 1. `pwd; rg --files -g '!lib/**' -g '!scratch/**' -g '!artifacts/**' | head -80`: `rg` panicked at `/rust/lib/rustlib/src/rust/library/std/src/thread/functions.rs:131:29`, unable to spawn a thread: `Resource temporarily unavailable` (OS error 11). The pipeline returned zero despite the failed search. 2. `rg --threads 1 --files -g '!lib/**' -g '!scratch/**' -g '!artifacts/**' | head -100`: shell reported repeated `fork: retry: Resource temporarily unavailable`; a later poll returned the repository file listing and exit zero. 3. `printf '%s\n' * docs/* reference/*`: exit 1, `bwrap: Creating new namespace failed: Resource temporarily unavailable`. 4. `cat docs/contracts.md reference/materialize.py`: succeeded; read the API contract and offline materializer. No materialization was performed. 5. `cat setup_fast.sh bootstrap/smoke_replica.py`: exit 1, same sandbox namespace failure. 6. Retried the preceding `cat`: exit 101, panic at `linux-sandbox/src/linux_run_main.rs:302:39`, `failed to prepare host proxy routing bridge: Resource temporarily unavailable (os error 11)`. Execution attempts started at approximately 06:37 UTC on 2026-11-10 and failed within the first few minutes, well below the 55-minute item cap and 480-second command limit. No installs, downloads, engine simulations, baseline generation, source modifications, or reference-byte changes were performed. Validation: 0 tests, 0/384 parity comparisons, 0 benchmark runs, no measured throughput, no input hashes computed, no baseline/spot-check runtime estimates available. Linux execution was attempted but could not be validated. macOS was not tested. No resumable simulation checkpoint exists because no simulation started. Resume by rerunning this assignment on a machine able to start sandboxed processes. Inspect `setup_fast.sh` and its documented arguments, use its pinned setup with `--cache scratch/cache`, materialize references with `reference/materialize.py`, and benchmark a small real workload before implementation. No functioning ammfast CLI or package was created, so there is no package resume command to report.
