"""The product test: the bake-off driven through CG Agent Harness, not straight at Ollama.

Every probe is one console turn (POST /api/chat over SSE) on a real `cgagentharness serve`: the harness's own
system prompt, history, compaction, token budgets, auto_tune, reasoning_effort "none" wire, web_search / web_fetch
loop, URL allowlist and grounding. The .app's webview calls this same backend.

Usage (keep bakeoff_7.py in the same folder; this file imports its prompts and graders):
  python3 bakeoff_harness.py --self-test --bin PATH        # disposable harness + bakeoff_7's fake Ollama
  python3 bakeoff_harness.py --dry-run
  python3 bakeoff_harness.py [--models substr ...] [--repeat N] [--quick] [--out DIR] [--bin PATH] [--port 8795]
         [--ollama http://127.0.0.1:11434] [--hvac json|prose|both|none] [--no-research] [--grant-file FILE]
         [--keep-home] [--no-contract-gate] [--allow-app]
  python3 bakeoff_harness.py --attach https://127.0.0.1:8790 [--home ~/.CGagentHarness]   # smoke only

Disposable is the comparison mode: fresh home on its own port (like scripts/smoke-ollama.sh), admin login, forced
password replacement, an "hvac" allowlist group, then deleted. --attach is a "my home still answers" smoke: your
notes, memory and persona confound the model, so its rows are marked not comparable and run three probes only.

Per model the lane:
  1. reads the tag contract directly (load with no num_ctx, /api/ps, /api/show) and calibrates chars/token;
  2. selects the tag, waits for auto_tune, and ABORTS unless /api/ollama/profile reports this tag at window 32768
     (the harness sends no num_ctx and will not raise the window for you);
  3. sends the /v1 body the harness sends and audits every reply for thinking (field, inline, hidden tokens);
  4. runs chat probes, a multi-turn session filled toward the loaded window with a needle in turn one (it records
     the measured prompt tokens and whether compaction kept the needle), web injection, HVAC research, and the
     dedicated /api/web/research pipeline whose 28000-token budget is what requires 32768;
  5. gates on: window contract, thinking off, no tool call on the injection note plus a real summary, research
     without budget warnings, no swap growth. Everything else is a profile. No model code is executed here.
