test(realizar): M32c.2.2.2.1.4 — live apr run falsifier pinning FALSIFY-QW3-MOE-FORWARD-003

[noahgift]

Summary

Adds a live integration test (F-QW3-MOE-C22214-001) that invokes
the user-facing apr binary as a subprocess against the cached
Qwen3-Coder-30B-A3B-Instruct-Q4_K_M.gguf and asserts:

1. exit 0
2. stdout contains ≥1 non-whitespace character

This pins the M32c.2.2.2.1.3 dispatch flip (PR #1126, squash
a902eea93) in CI / regression-prevention. Without it, a future
regression that re-routed qwen3_moe back to the dense
run_gguf_generate path (which produces garbage on MoE weights)
would slip through CI silently — there'd be no signal at the
apr run user-facing surface.

Live evidence (lambda-vector RTX 4090, 2026-04-29)

test f_qw3_moe_c22214_001_apr_run_emits_at_least_one_non_whitespace_char ...
F-QW3-MOE-C22214-001: elapsed = 130.945370974s
  stdout: === APR Run === ... Output: . ... Completed in 130.83s (cached)
F-QW3-MOE-C22214-001: PASS
test result: ok. 1 passed

The single emitted character . (period) is enough to discharge
FALSIFY-QW3-MOE-FORWARD-003 — quality vs llama.cpp Q4_K (cosine on
logits) is M32d's job.

Skip path

CI runners (no cached GGUF) print
F-QW3-MOE-C22214-001: SKIP — no cached Qwen3-Coder GGUF at any of [...]
and return success. Same skip pattern as
crates/aprender-serve/tests/qwen3_moe_forward_one_token.rs
(M32c.2.2.2.1.1 in-process forward primitive).

Contract chain status

Slice	Status	PR
M32a — contract scaffold	SHIPPED	#1099
M32b — arch-aware FFN load refuses qwen3_moe	SHIPPED	#1100
M32c.1+ — MoE descriptor load + byte slicer	SHIPPED	—
M32c.2.2.2.1.1 — forward_qwen3_moe method	SHIPPED	#1124
M32c.2.2.2.1.2 — run_qwen3_moe_generate	SHIPPED	#1125
M32c.2.2.2.1.3 — dispatch flip + Q4_K_M qtype	SHIPPED	#1126
M32c.2.2.2.1.4 — live apr run falsifier	THIS PR
M32d — numerical parity vs llama.cpp	PENDING

After M32d, qwen3-moe-forward-v1 flips DRAFT → ACTIVE_RUNTIME,
unblocking the companion-repo FALSIFY-CCPA-013 measured
tool-dispatch parity gate.

Test plan

• cargo test -p apr-cli --test qwen3_moe_apr_run_live_falsifier --no-run — compiles
• cargo clippy -p apr-cli --test qwen3_moe_apr_run_live_falsifier -- -D warnings — clean
• Live run on lambda-vector against cached 17.3 GB GGUF — PASS (130.83s, emitted ".")
• CI workspace-test — passes via SKIP path (no GGUF on runners)
• Lambda-vector full workspace test post-merge
