KV cache quantization adds type_k/type_v columns to llama-bench output,
shifting test and t/s to different indices. Parse from end of row instead
of hardcoded positions. Also fix KV suffix separator (underscore to dash)
to avoid regex ambiguity with type names like q8_0.
Add 5-phase optimization guide, optimization log for tracking results,
and research docs on llama.cpp and inference landscape optimizations.
Standard benchmarks use pp512/tg128 which underestimates real-world
agentic coding where responses are 500-2000 tokens. Now configurable:
--pp N Prompt processing tokens (default: 512)
--tg N Token generation count (default: 128)
Examples:
benchmark run --tag realistic --tg 1024 --pp 2048 --category moe
benchmark run --tag full-response --tg 2048 --category moe --reps 3
Log filenames include pp/tg when non-default (e.g., model__backend__fa1__pp2048_tg1024.log)

Both run-baseline.sh and run-suite.sh now accept --context N to set
the long-context depth (default: 32768). Prompt tokens auto-scale to
~1/16 of context depth for larger windows.
Examples:
benchmark run --tag ctx64k --context 65536 --category moe
benchmark run --tag ctx128k --context 131072 --category moe --reps 3

The metric logger is killed via SIGTERM on benchmark completion, producing
exit code 143 (128+15) which propagated through set -e. Added explicit
return 0 / trailing true to cleanup traps.

ROCm 7.2 is now created alongside vulkan-radv during setup, giving
Vulkan vs ROCm comparison in baseline and post-optimization benchmarks.
Smoke test: ROCm 7.2 on Qwen3.5-0.8B → 8090 t/s pp512, 161 t/s tg128
(vs Vulkan: 8900 t/s pp512, 177 t/s tg128)

Toolbox containers mount host / at /run/host/ but only /home is directly
accessible. Models on /data/models/ need the /run/host/ prefix when passed
to llama-bench inside the container.
Both run-baseline.sh and run-suite.sh now resolve model paths with realpath
and prepend /run/host/ for non-home paths. Paths under /home/ are passed
as-is (already mounted directly).
Verified with smoke test: Qwen3.5-0.8B-Q8_0 → 8900 t/s pp512, 177 t/s tg128.

- Catalog * indicator now searches recursively (finds models in subdirs)
- GPU verification suppresses toolbox crun stderr (directory not found noise)
- Matches on "radeon" and "available devices" for Vulkan output

Both run-baseline.sh and run-suite.sh now support:
- --max-size GB: skip models larger than N GB (prevents OOM)
- --category LIST: filter by catalog category (smoke,dense,moe)
- --skip-longctx: skip 32K context tests (saves time + memory)
- --reps N: configure repetition count
- --help: shows usage with examples
Safe pre-optimization run: benchmark baseline --max-size 20 --skip-longctx
Full post-optimization: benchmark baseline (no filters, all models + longctx)
Also: 4 new BATS tests for flag parsing (98 total, all passing)

Models:
- configs/models.conf: catalog with Qwen3.5-35B-A3B (MoE, top pick),
Qwen3.5-27B (dense), Qwen3-Coder-30B-A3B (agentic/coding)
- Updated benchmark setup to show catalog with download status
- docs/model-recommendations.md: memory planning, quantization guide
Agentic evaluation:
- scripts/agentic/setup.sh: installs inspect-ai, evalplus, bigcodebench
in a Python venv
- scripts/agentic/run-eval.sh: runs evaluations against local LLM server
(ollama or llama.cpp). Suites: quick (HumanEval+IFEval), code
(EvalPlus+BigCodeBench), tooluse (BFCL), full (all)
- bin/agentic: dispatcher with help
- docs/agentic-benchmarks.md: methodology, framework comparison, model
recommendations for agentic use
Updated: Makefile (6 new targets), README, CLAUDE.md, docs/references.md

Bugs fixed in production code:
- compare.sh: Python truthiness on 0.0 — `if b_val` was False for 0.0 t/s,
displaying it as a dash instead of "0.0". Fixed with `is not None` checks.
- compare.sh: ZeroDivisionError when computing delta % with 0.0 baseline.
Test improvements (review findings):
- detect.bats: kernel param tests now use real detect_kernel_param logic
pattern (not a separate reimplementation). Added non-GiB-aligned RAM test,
device ID without 0x prefix, empty firmware version, llama-bench detection,
detect_total_physical_ram_kb tests.
- benchmark_compare.bats: assert delta percentages (+20.0%, -25.0%, 0.0%),
test 0.0 t/s edge case, test per-directory error messages, test config
change detection with specific field assertions.
- log_metrics.bats: add assert_success, --help test, timestamp format
validation. Remove unused mock sysfs setup.
- common.bats: fix data_dir test, remove redundant assertion, add cleanup.
- test_helper.sh: remove unused FIXTURES_DIR.
- Remove empty tests/fixtures/ directory.
94 tests, all passing.

- Replace GNU \b with portable word-boundary sed patterns in kernel-params
- Warn on unknown CLI arguments instead of silently swallowing
- Add floor check on recommended_gttsize_mib to prevent negative values
- Fix Python operator precedence in benchmark log parser
- Add root checks to tuned-profile.sh and rollback.sh
- Remove redundant sudo calls (scripts already require root at entry)
