preflight: rocm7-0-34-4-dynres for the v0.34.4 fold, measured on gfx1151

[glennneuber]

This PR adds gate 5's rocm7 profile for the v0.34.4 fold. It targets #375's branch, not main. I measured and ran it on gfx1151 only, and it touches no other platform's profile.

What

rocm7-0-34-4-dynres in expectations.toml. Until now, no rocm7 profile admitted a version after 0.34.1, so preflight on the ROCm host could not resolve the fold at all (exit 2).

• Pin. llama_cpp_build = "161755f29" (b11081), read through the container route preflight: read llama-server's sha from its version line, not by position #376 fixed.
• Toolchain. toolchain_build = "rocm-7.2.4". The image is built with Dockerfile.rocm on rocm/dev-ubuntu-24.04:7.2.4-complete (ADR 0042).
• Patch set. 001 002 004 005 801 802 903. There is no 906: upstream's own HIP revert shipped by b10969, and 906 was retired with it.
• Version pattern. ^0\.34\.[34]-dynres-\d+-g… matches the fold's gate images before v0.34.4-dynres is cut and after. A 0.34.3 build on b10969 also matches, and then fails payload_pin, which is the right answer for it.
• Ladders. measure_ladder.py measured them on the fold image, and I pasted its output whole (ADR 0012 rule 8). They equal rocm-0-34-1-dynres's exactly: nemotron [266, 266, 578, 2306, 3270], gemma4 [1102]×5, qwen35 [1034, 1034, 1034, 2306, 4082]. That is expected, because tools/mtmd changed between b10969 and b11081 by one error-handling hunk only.

First run: VERDICT PASS

preflight.py --platform rocm7 --quality against maxusai-ollama:0.34.3-dynres-5-g29ae523-rocm7-gfx1151 (built from 29ae52351), on a container of its own, gave PASS=20 SKIP=12:

• payload_pin, toolchain_pin, image_tag and go_patch_marker;
• the three token ladders 5/5, the three payload proofs, and the text baselines 19/19/13;
• the pinned budgets: nemotron 3328 → 3270 and gemma4 560 → 529;
• think_format on all three archs through the fold's single pass: valid JSON after thinking, in 1401, 127 and 273 tokens;
• endpoint_exclusive: no contention.

All the skips predate this profile. No rocm7 profile has recorded a poison-probe, aspect or extraction-quality expectation. The run record is committed as runs/preflight-rocm7-0344-fold-g29ae523.json. It is force-added past the runs/ ignore, as the other cited records are.

Verification

• python3 test_verdicts.py passes: 196 tests OK, 6 skipped.
• tomllib loads the file.
• To reproduce on gfx1151, start the fold image on a free port and run:

  preflight.py --host <it> --platform rocm7 --container <it> --quality
