- Line 115: Update the readiness validation around the ready variable so that
when readiness is not achieved, it prints the fixture diagnostics from
"$RUNNER_TEMP/isolated-hermes-smoke.log" before exiting with failure; retain
successful continuation when ready equals 1.
In `@scripts/install_hermes.py`:
- Around line 33-41: Update checkout to verify the existing repository’s origin
matches HERMES_REPOSITORY before fetching or checking out ref. Retrieve the
origin URL using the existing subprocess utilities, reject mismatches with
SystemExit, and leave the fetch and detached checkout flow unchanged for
matching repositories.
In `@src/avo_harness/gitops.py`:
- Line 42: Strip inherited Git repository-location variables from the copied
environment before configuring Git subprocesses, including GIT_DIR,
GIT_WORK_TREE, GIT_COMMON_DIR, GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY,
GIT_ALTERNATE_OBJECT_DIRECTORIES, and GIT_PREFIX. Add a regression test that
sets these variables and verifies fake_run does not receive them.

Security Misconfiguration
Reachability: Internal
Exploitability: Difficult
CWE: CWE-15
Strip inherited command-scope Git configuration variables.
_trusted_repo_env copies the process environment. The CLI and child launchers inherit that environment, and _git passes it to git commit. GIT_CONFIG_COUNT, GIT_CONFIG_KEY_n, GIT_CONFIG_VALUE_n, and GIT_CONFIG_PARAMETERS take precedence over the temporary GIT_CONFIG_GLOBAL, so an untrusted parent environment can set core.hooksPath. The API request itself does not set these variables.
Remove these variables and test that they are absent.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Why
The existing fixes made the Docker image capable of resolving
nvidia.fabric.hermes, but the documented local install still installed only.[web]. Worse,avo-harness doctortreatedimport nemo_fabricas proof that the worker was usable, so an environment withavailable adapters: []could report healthy and fail only when a request actually ran.What changed
doctorresolve each configured NeMo adapter and runFabric.doctor()without contacting the modelinit+doctorADAPTER_PYTHON, fixing an environment leakage race between concurrent workersPython 3.11-3.13, source Hermes,.[web,nemo])ADAPTER_PYTHONisolationAcceptance
A fresh supported install must fail CI unless:
nvidia.fabric.hermesresolves through NeMo Fabric.avo-harnessCLI can generate the default config anddoctorit from outside the source tree.pip checkpasses in both the clean package environment and final Docker image.The smoke path intentionally makes no model/API call.
