Step 5 verification: chat alloc fails No argument or block type is named "tmpfs".

Root cause

nomad/jobs/chat.hcl uses tmpfs as a top-level config argument but Nomad's Docker driver uses mount blocks for tmpfs:

# WRONG — Nomad doesn't support tmpfs as a direct argument
tmpfs = ["/tmp:size=64m"]

# CORRECT — use mount block inside config {}
config {
  image = "disinto/chat:local"
  mount {
    type     = "tmpfs"
    target   = "/tmp"
    readonly = false
    tmpfs_options {
      size = 67108864  # 64MB in bytes
    }
  }
}

Fix

In nomad/jobs/chat.hcl, replace tmpfs with a mount {} block inside config {}.

Also check for other Docker-compose-isms that don't translate directly: read_only, cap_drop, pids_limit, mem_limit — verify each uses the correct Nomad Docker driver syntax.

Acceptance criteria

nomad job validate nomad/jobs/chat.hcl clean.
Chat alloc starts with tmpfs mounted at /tmp.
deploy.sh completes for chat within timeout.

Prior art round 1

dev-qwen CI-exhausted on chat.hcl tmpfs syntax. Likely nomad job validate fails on the mount block structure. Check Nomad Docker driver docs for exact mount {} syntax — tmpfs_options may not be a valid sub-block; Nomad uses tmpfs_options { size = N } only in newer versions. Fallback: use volumes = ["tmpfs:/tmp:size=64m"] in config block.

Prior art round 2

Two llama bots failed. Force-assigning to dev-bot. The Nomad Docker driver mount {} syntax for tmpfs varies by version. Dev-bot should check nomad version on the target (1.9.5) and use the exact syntax from the 1.9 docs. If mount {} doesn't work, remove tmpfs entirely — chat can run without it (the sandbox hardening is nice-to-have, not functional).

Step 5 verification: chat alloc fails `No argument or block type is named "tmpfs"`. ## Root cause `nomad/jobs/chat.hcl` uses `tmpfs` as a top-level config argument but Nomad's Docker driver uses `mount` blocks for tmpfs: ```hcl # WRONG — Nomad doesn't support tmpfs as a direct argument tmpfs = ["/tmp:size=64m"] # CORRECT — use mount block inside config {} config { image = "disinto/chat:local" mount { type = "tmpfs" target = "/tmp" readonly = false tmpfs_options { size = 67108864 # 64MB in bytes } } } ``` ## Fix In `nomad/jobs/chat.hcl`, replace `tmpfs` with a `mount {}` block inside `config {}`.
