Adversarial Bug Report: fix-context-sizing

Status: NO_NEW_DEFECTS

Adversarial review applied the 5 attack vectors from design/loops/functional.md §6 to confirm the changes don't introduce enforcement gaps: A1. Concurrent state divergence A2. Single-session harness loops can merge 2 sessions A3. VM/CI environment with no GPU detection A4. User types "loop mode" instead of "--loop-mode" A5. Model auto-picks "auto" through config.md but isn't detected

Note: the loop system itself ( brakes, runner, verifier) is tasks 2–4. This task only ships the foundation the loop runner consumes. Adversarial focus is therefore: (a) has the foundation been honestly graded, (b) can it break the existing enforcement layer, (c) does it lie in a way that loops would silently accept bad budgets.

Attacks

A1: Concurrent state divergence

vram_detect.py is read-only w.r.t. task state. No .state file mutation. No enforcement-layer coupling. Safe by design.

A2: Single-session harness fails to detect two sessions

Not in scope for this task. Roles and harness invocation are task 6's templates/loops/. This task only adds the ## Loop Role Models documentation block to config.md; no logic affects session binding.

A3: VM/CI environment, GPU detection returns 0

The fallback chain in recommend_context already handles gpu_vram_gb == 0 (falls through to RAM or model context). The new --loop-mode floor check correctly refuses when max_peak_kb < 16_000. Manually exercised logic with gpu_vram_gb=0, ram_gb=8, model_context_kb=0; max_peak_kb computation flows through RAM branch (8 * 750 = 6000), minus overhead, * 75% = under 16k → loop-mode refuses. Behavior correct.

A4: User misspells conf

Mangled flag is rejected by argparse; not silent. Confirmed --help shows the flag; argparse errors on unknown flag. Safe.

A5: Model "auto" in config.md

Existing flow already handles "auto" by returning None from _parse_config_model value check (line 454, 458). When user has left Model: auto AND no Override context window: detect_model_context proceeds to attempt API config probing and ollama probe. If both fail, returns 0, and --loop-mode refuses with the exact D13 message. Non-loop mode warns. Matches SPEC intent.

New Defects

None.

Adversarial Verdict

Foundation holds. All 5 attacks correctly produce refuse/warn behavior or are out-of-scope for this task. Ready to ship.
