Owner

The blocker after the bicep fix (#151). Diagnosed from Forgejo's action-log storage and reproduced on the runner: even with nixpkgs#bicep on PATH and use_binary_from_path=true, az deployment group create crashes on the NixOS runner:

ERROR: 'NoneType' object has no attribute '__name__'

The nixpkgs azure-cli's az deployment command module is broken (same class as the az aks nodepool add SDK crash documented in aks-cost-experiment.md). Confirmed on vxrail that BOTH the .bicep and a pre-compiled .json crash identically and early → it's the command module, not bicep. az rest against the ARM deployments API works (validated on the runner: provisioningState: Succeeded).

Fix (deploy/azure/gate.sh + workflow):

deploy() helper: compile the bicep to ARM JSON with nix bicep, submit via az rest PUT, poll provisioningState; dep_output() reads outputs via az rest GET. Both vms + aks deploy sites use it.
Off-NixOS laptops (no bicep on PATH) keep using az deployment group create unchanged.
workflow: add nixpkgs#python3 (deploy() builds the ARM payload with it).

Note: this supersedes Ben's #153 (which is the same bicep fix already merged as #151) — #153 can be closed. This one goes a layer deeper to the actual deploy crash.

Even with bicep on PATH (#151), 'az deployment group create' crashes on the
NixOS runner with 'NoneType object has no attribute __name__' — the nixpkgs
azure-cli's deployment command module is broken (same class as the az aks
nodepool add crash in the ops runbooks). Proven on the runner: 'az rest'
against the ARM deployments API works.

gate.sh: a deploy() helper compiles the bicep to ARM JSON (nix bicep) and
submits it via 'az rest' PUT, polling provisioningState; dep_output() reads
outputs via 'az rest' GET. Laptops without bicep on PATH keep using
'az deployment group create'. Both vms + aks deploy sites use the helper.
workflow: add nixpkgs#python3 (deploy() builds the ARM payload with it).

Diagnosed from Forgejo's own action-log storage (job-log API 404s) and
reproduced/fixed directly on the vxrail runner via az rest validate.
