The drift gate's monorepoRoot walk-up looked for workspace-configs-templates/
which is gitignored locally and doesn't exist in this repo at all (the
canonical script lives in molecule-ai-workspace-template-hermes). Test
failed on CI from day one with "could not find monorepo root".
Two layered fixes in one PR:
1. Vendor upstream derive-provider.sh as testdata/ + drop monorepoRoot.
The vendored copy has a header pointing operators at the upstream
source and a one-line cp command for refresh. Test now reads two
files (vendored shell + workspace_provision.go) via package-relative
paths — Go test sets cwd to the package dir, so this is hermetic
without any walk-up gymnastics.
2. Update the case-statement regex to match upstream's renamed variable
(${_HERMES_MODEL} since v0.12.0, the resolved value of
HERMES_INFERENCE_MODEL with a HERMES_DEFAULT_MODEL legacy fallback).
Regex now accepts either spelling so a future rename fails loudly
on the parser-sanity check rather than silently returning empty.
Vendoring upstream surfaced real drift the gate was designed to catch:
upstream v0.12.0 added 12 provider prefixes that deriveProviderFromModelSlug
didn't handle (xai/grok, bedrock/aws, tencent/tencent-tokenhub, gmi,
qwen-oauth, lmstudio/lm-studio, minimax-oauth, alibaba-coding-plan,
google-gemini-cli, openai-codex, copilot-acp, copilot). Without these,
Save+Restart on a workspace using one of those prefixes would persist
LLM_PROVIDER="" and the next boot would fall back to derive-provider.sh's
runtime *=auto branch — losing the user's explicit choice on every restart.
Added all 12 case clauses + 16 new table-driven test cases (covering
both canonical and aliased forms). Drift gate now passes; future
upstream additions will fail loudly with a "DRIFT: ..." message
pointing the engineer at the missing case.
Task: #242
